Detailed introduction to modified asphalt tank equipment

With the rapid development of our country’s social development and the continuous development of economic and information technology, modern highway construction is also developing rapidly, and the requirements for ground structural materials are becoming higher and higher, and Asphalt concrete bonding raw materials are inseparable from modified asphalt equipment. So besides these influencing factors, what other reasons does the company have that people don’t understand? Let’s analyze it together.
There are some asphalt concrete equipment on the market, because they have not solved the problem of asphalt clogging before grinding, there are not enough preparation equipment and grinding equipment, the structure is unscientific, and the entire grinding process cannot achieve a certain particle size, resulting in modification. The product productivity of asphalt equipment is low and the product quality is unstable. It requires continuous grinding for a long time, creating problems. This will not only greatly increase energy consumption, increase costs, make product quality unstable, and affect the speed of highway construction.

In addition to being used according to regulations, modified bitumen equipment should also be maintained regularly in order to effectively extend the service life of modified bitumen equipment. The delivery pump of modified bitumen equipment, as well as its motor and reducer, need to be maintained in accordance with the specifications of the instructions. If the modified bitumen equipment is parked for a long time, the liquid in the tank and pipeline needs to be drained, and each moving component also needs to be filled with grease. The dust in the control box of the modified bitumen equipment needs to be cleaned once every six months. A dust blower can be used to remove dust to prevent dust from entering the machine and damaging parts. The micro powder machine needs to add unsalted butter once for every 100 tons of emulsified bitumen produced.

Abstract: Asphalt melting equipment is one of the indispensable equipment in modern road construction. Its main function is to heat a large amount of cold hard asphalt to a suitable working temperature at the construction site. Advanced asphalt melting equipment can greatly improve construction efficiency, reduce human resources and time costs, and ensure pavement quality at the same time.

Bitumen emulsifier is a surfactant. A surfactant is a compound that reduces the surface tension between two liquids, a gas and a liquid, or a solid and a liquid. Surfactants are mainly used in: detergents, detergents, fabric softeners, wetting agents, emulsifiers, foaming agents, dispersants, adhesives, etc.

How to reduce energy consumption of emulsified asphalt machinery is a concern of many users and many manufacturers. Therefore, today, Sinosun Company, as a manufacturer of emulsified asphalt equipment, would like to take this opportunity to share with you the method of reducing energy consumption of emulsified asphalt machinery.
Since emulsified asphalt appears as a finished product in emulsified asphalt machinery, and the outlet temperature of ordinary emulsified asphalt is about 85℃, and the outlet temperature of emulsified modified asphalt is above 95℃, there is a lot of latent heat in emulsified asphalt, but the emulsified asphalt equipment does not make good use of them, but directly enters the finished product tank, allowing heat to be lost at will, resulting in energy waste.

Asphalt melting equipment is a mechanical equipment specially used to heat and melt asphalt. Our company’s products have been widely recognized and applied in the market.
Our main production process is: transporting the high-temperature oil and gas generated after high-temperature cracking of raw materials (such as petroleum) in the combustion chamber to high-speed rotating heat-conducting oil tankers for heat transfer, melting, cooling and other processes, and finally obtaining the required finished materials or Semi-finished materials. The advantage is that it can make the best use of raw materials and reduce energy consumption; at the same time, it can also customize products of different specifications according to different needs to meet the different requirements of customers. In addition, we provide after-sales service and technical support to protect the interests and safety of our customers.

Friends who are ready to get started have a surprise today. The editor will give you a brief introduction on how to produce emulsified asphalt.

What is an bitumen colloid mill used for? Everyone knows about colloid mill, but what about bitumen colloid mill?
Bitumen colloid mill is a high-tech multifunctional crushing and grinding equipment. The motor drives the rotating teeth and fixed teeth to rotate at high speed, generating a sharp speed gradient, which causes the boring to be strongly sheared, rubbed and turbulent, and finally achieves emulsification and dispersion. and homogenizing effect equipment.

I believe everyone is familiar with the relevant knowledge about modified bitumen equipment. As users continue to increase its application, we have also talked about it a lot in the above articles and learned that it is mainly engaged in the production of modified bitumen. Production, in order to further enhance users’ understanding of it, professionals summarize its relevant characteristics as follows:

Everyone has a side of themselves that they don’t want others to know. As a preventive road maintenance technology, slurry sealing has some shortcomings. do you think so?
Slurry seal is a kind of road protection that uses special equipment to mix emulsified asphalt, water, additives, aggregates, fillers and other ingredients in a certain proportion, and then mixes the slurry mixture onto the original road surface to form a thin layer. Maintenance technology. These are all well known. The editor will not go into details on this.

Emulsified asphalt can be spread by mechanical spreading and manual spreading. Different spreading methods will have different effects on pavement performance, so it is very important to choose the right spreading method. At the same time, maintenance and management after spreading are equally important to ensure the safety and durability of the pavement.
Emulsified asphalt is a common pavement material that is widely used in road construction and maintenance. There are two main ways to spread emulsified asphalt: mechanical spreading and manual spreading. Mechanical spreading generally uses a special spreading vehicle that can quickly and evenly spread emulsified asphalt. Manual spreading is carried out by workers using tools such as brushes or rollers, which is suitable for pavement treatment in small areas or special areas.
Different spreading methods also have different effects on pavement performance. Mechanical spreading can quickly complete large-area treatment and spread evenly, which is conducive to ensuring the flatness and anti-skid properties of the pavement. Manual spreading can more finely treat special areas such as shoulders and intersections to improve the overall performance of the pavement.

For the relevant knowledge of modified asphalt equipment, we have more or less introduced it in the above articles. I believe that most users also have some simple understanding of it. Today we also mastered:
In order to meet the different requirements of customers, the configuration and process of the equipment produced by the manufacturers of modified asphalt equipment are diversified. There are fixed production types, mobile types, and imported main machines, but the imported main machines are expensive, so most customers configure domestic pipeline emulsifiers or colloid mills. In terms of the degree of automation, there are fully automatic production and semi-automatic production. Regardless of the form of production, each has its own advantages and disadvantages. What kind of process and configuration is used depends on the annual production volume and the customer’s requirements for equipment, product performance requirements and other factors. I hope that these introductions can help users choose to a certain extent.

There are many types of emulsified bitumen, and PC-2 is one of them, which is a spray-type emulsified bitumen. It is used for spraying oil through the base layer of granular materials and health care spraying on semi-rigid base layers. There is also the PA-2 type, which has the same purpose as the PC-2 type. The difference is that the PC-2 type is a cation, while the PA-2 type is an anion.

Microsurfacing is a thin layer of overlay placed on old asphalt pavement and is a type of preventive maintenance process. The purpose of microsurfacing is road maintenance. After micro-surface paving, it can repair cracks in the original road surface, waterproof and beautify the road surface.
The construction method of micro surfacing is: using a micro surfacing paver to evenly spread modified emulsified asphalt, a certain grade of mineral materials, water and other additives on the road surface in a certain proportion.

The bitumen (composition: asphaltene and resin) drum melting machine adopts a self-heating integrated structure, which integrates the thermal oil boiler used in the old asphalt drum melting machine and the barrel removal equipment itself, reducing the volume of the entire equipment and significantly It reduces equipment investment (actual significance: it is the accumulation of future profits), saves the space occupied by the equipment and the logistics cost of switching sites. The combustion chamber is placed inside the equipment itself, which greatly reduces thermal damage and improves heat utilization.

In our daily life, we can often see emulsified asphalt equipment. Its appearance has brought us great convenience. So what is the difference between its modification process? Below, the editor will give you a brief introduction to the relevant knowledge points.
1. Emulsified asphalt equipment first emulsifies and then modifies: This is a relatively simple way to make modified emulsified asphalt. The production process is to grind hot asphalt and emulsifier soap together through a colloid mill to make ordinary emulsified asphalt, and then add latex-like modifiers to the emulsified asphalt through mechanical stirring to make modified emulsified asphalt. The characteristic of this method is that it does not require high equipment.

The heating principle of asphalt decanter equipment is to heat, melt and decanter the asphalt through the heating plate. It is mainly composed of de-barreling box, lifting system, propeller and electrical control system.
The box of asphalt decanter plant is divided into upper and lower chambers. The upper chamber is the asphalt melting chamber, which is densely covered with heat transfer oil heating coils or hot air heating pipes. The asphalt is melted and removed from the barrel by heat. The hoisting hook is installed on the gantry, and a barrel grabber is hung. The asphalt barrel is lifted by the electric winch, and then the asphalt barrel is placed on the guide rail by horizontal movement. Then the propeller pushes the barrel into the upper chamber through two guide rails, and an empty barrel is pushed out at the rear end outlet.
An anti-drip oil tank is provided at the entrance of the asphalt barrel. The asphalt enters the lower chamber of the box and is continuously heated to a temperature of about 100 to be transported, and then pumped into the asphalt tank by the asphalt pump. The lower chamber can also be used as an asphalt heating tank.
The asphalt decanter plant has the characteristics of not being restricted by the construction environment, strong adaptability and extremely low failure rate. If large production is required, multiple units can be assembled.

From the current point of view, road construction machinery has bottomed out and asphalt meltering equipment has risen rapidly. In recent years, highway construction and maintenance departments have a strong awareness of using asphalt mixing equipment, especially in developed coastal areas such as Beijing, Shanghai, Jiangsu, Zhejiang, etc. In addition, these regions have a fast economic growth rate, relatively developed industry, and strong comprehensive economic strength. Therefore, the consumption of asphalt mixing equipments in these regions has always been at the forefront of the country. With the rapid development of highway construction and the increase in demand for asphalt, barreled asphalt has been widely used for its convenient transportation and easy storage. In particular, most of the high-performance imported asphalt used in high-grade highways is in barrel form, which requires an asphalt meltering equipment with fast melting speed, clean de-barreling, and can prevent asphalt aging. my country’s highway construction has achieved remarkable results, among which mechanized production has contributed greatly. Different types of asphalt mixers and bitumen meltering equipment are selected for the characteristics of large highway pavement construction and tight construction period. With the rapid development of my country’s economy, the further extension of expressways, and the large-scale development of western construction, the central and western regions have become new investment hotspots. While paying attention to the market in the developed eastern regions, domestic road construction machinery manufacturers have also increased their efforts to develop the central and western markets, creating new highlights for the domestic asphalt mixing plants consumer market. In summary, my country’s asphalt mixing plant sales market has begun to move westward with the westward movement of investment hotspots. As the market center of gravity gradually shifts westward, the market in the western region is gradually heating up. The self-heating integrated structure, hot air barrel melting and bitumen barrel flipping technology in the asphalt barrel removal equipment are our company’s self-heating integrated structure. The thermal oil furnace used in the old equipment is perfectly integrated with the asphalt barrel removal equipment body, which reduces the volume of the entire set of equipment, greatly reduces equipment investment, saves equipment space and transfer transportation costs.

Some of the equipment of emulsified modified bitumen equipment are as follows. The specially made bitumen filter can effectively filter the residues and dirt in the high-temperature culture medium bitumen to avoid damage to the subsequent equipment. The emulsified modified bitumen equipment adopts a spiral plate type or a shell and tube heat exchanger to quickly heat the culture medium bitumen through high-temperature heat transfer oil to meet the needs of the production process. The emulsified modified bitumen equipment is heated in the storage tank to prevent the bitumen from aging due to long-term high-temperature heating and exposure to the air. The sulfate generated during the production process of the emulsified modified bitumen equipment is very limited, reducing air pollution.
The emulsified modified bitumen equipment sends the modified material manually poured into the dumping bin to the bitumen batching tank by wind or spiral. It can be equipped with a metering and calibration system. The emulsified modified bitumen equipment thickener is automatically or manually added. The emulsified modified bitumen equipment can be equipped with a metering and calibration system. Emulsified modified bitumen equipment transportation and metering and calibration system, the emulsified modified bitumen equipment adds the set bitumen amount to the batching tank through the frequency converter and computer interlock. The emulsified modified bitumen equipment and bitumen steam flowmeter use big brand products to ensure the preparation.

The base layer of asphalt pavement is divided into semi-rigid and rigid. Since the base layer and the surface layer are materials of different properties, good bonding and continuity between the two are the key requirements for this type of pavement. In addition, when the asphalt surface layer seeps water, most of the water will be concentrated at the joint between the surface layer and the base layer, causing damage such as slurry, looseness, and potholes to the asphalt pavement. Therefore, adding a lower seal layer on top of a semi-rigid or rigid base layer will play a vital role in enhancing the strength, stability and waterproofing capabilities of the pavement structural layer. The more commonly used one is to use asphalt gravel synchronous sealing technology.
So let’s take a look at how the construction of the asphalt gravel synchronous sealing truck is carried out:

Emulsified asphalt is an emulsion that disperses asphalt into the water phase to form a liquid at room temperature. This determines that emulsified asphalt has many technical and economic advantages over hot asphalt and diluted asphalt. We know that modified asphalt equipment is a road engineering machinery. In order to better promote users’ understanding of it, today the editor will introduce its characteristics to you so that users can better understand that modified asphalt equipment is used for modified asphalt.

Asphalt mixture mixing equipment is a factory-style complete set of equipment that mixes dry and heated aggregates of different particle sizes, fillers and asphalt according to the designed mix ratio at a specified temperature into a uniform mixture. It is widely used in high-grade highways and urban roads. , airports, docks, parking lots and other engineering construction. It is a key equipment for asphalt pavement construction, and its performance directly affects the quality of asphalt pavement.
Generally, there are two types of asphalt concrete mixing equipment: intermittent type and continuous type. The continuous process flow is simple and the equipment is simplified. As for the intermittent forced mixing equipment, due to the secondary screening of aggregates, various components are measured in batches, and forced stirring and mixing can reliably ensure gradation, and the measurement of powder and asphalt can also achieve very high accuracy; so the mixing equipment The asphalt mixture produced is of high quality and can meet various construction requirements.

1. Preparation before construction
2. Mix
3. Paving
4. Leveling
5. Shutdown
6. Overlap
7. Crush

Due to the incorporation of a certain proportion of water into the slurry sealing mixture, it is easy to evaporate in the air. After the water is evaporated, it will become dry and hardened. Therefore, after the slurry is formed, it not only looks very similar to fine-grained asphalt concrete, but does not affect the visual appearance of the road. It also has the same technical properties as fine-grained concrete in terms of wear resistance, anti-skid, waterproofing, and smoothness. Slurry seal technology is used in highway pavement maintenance because of its simple construction technology, short construction period, low cost, high quality, wide application, strong adaptability, etc. It is an asphalt with both economy and high efficiency. Pavement maintenance technology is worthy of application and promotion.
