How to reduce the energy consumption of emulsified asphalt production equipment?

Asphalt melting equipment follows the continuous development of urbanization. Whether in rural areas or in big cities, you can see a lot of construction sites, among which it is inevitable that asphalt melting equipment is set up nearby. Asphalt melting equipment manufacturers, whether large or small asphalt melting equipment or relatively large and small, although it is just a simple mechanical equipment, but to move or transport it, it is a small matter, and there are many places that require attention.
The technical level of the asphalt melting equipment disassembly and assembly team directly affects the disassembly and assembly progress of the asphalt melting equipment; improve on-site supervision, reasonably organize disassembly and assembly machinery and equipment and workers, try to avoid cross-operation, and promote the disassembly and assembly process to consume less manpower and machinery shifts to do a good job in the transportation of asphalt melting equipment; ensure that the asphalt melting equipment is not damaged and the prefabricated components are not missed.

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.

Here is an introduction to the knowledge on construction quality control of modified rubber asphalt equipment. Let’s introduce this knowledge from three aspects. The details are as follows: The viscosity of the modified asphalt mixture of modified rubber asphalt equipment is relatively high, and the construction temperature of each process is The construction temperature requirements are higher than those of ordinary asphalt mixtures.

Synchronized gravel sealing is to use special equipment, namely a synchronous gravel sealing truck and bonding materials (modified asphalt or modified emulsified asphalt) to be spread simultaneously on the road surface, and then formed into a single layer through natural traffic rolling or tire roller rolling. A layer of asphalt gravel wearing layer, which is mainly used as the surface layer of the road, and can also be used for the surface layer construction of low-grade highways.

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.

Asphalt spreading trucks are used to spread the permeable oil layer, waterproof layer and bonding layer of the bottom layer of asphalt pavement on high-grade highways. It can also be used in the construction of county and township-level highway asphalt roads that implement layered paving technology. It consists of a car chassis, an asphalt tank, an asphalt pumping and spraying system, a thermal oil heating system, a hydraulic system, a combustion system, a control system, a pneumatic system, and an operating platform.

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.

What is the overall operation process of bitumen (composition: asphaltene and resin) drum melting equipment?
The bitumen (composition: asphaltene and resin) drum melting equipment produced by our company mainly uses barrel debarking and melting of large barrels of bitumen (definition: the transformation process of materials from solid to liquid), using high-temperature thermal oil as the material (playing a decision-making role substance), used in supporting facilities of high-temperature thermal oil heating equipment. Bitumen drum melter equipment has the functions of barrel delivery, barrel removal, storage, temperature raising, slag discharge, etc. It is an essential product for high-grade highway construction companies. Bitumen drum melter equipment can be used for resin barrel removal. The bitumen drum melter equipment mainly consists of barrel removal shell, hoisting mechanism, hydraulic booster and electrical control system.

The equipment of each part is used as follows: Water treatment system: Mechanical filtration of ordinary tap water absorbs resin exchange reactions, turning high-hardness tap water into pure soft water and reducing water tension. , enhance the emulsification effect of asphalt or modified asphalt.

The slurry seal truck is mainly used for preventive maintenance of municipal pavement. It can improve the quality of the seal, effectively improve the integrity and crack resistance of the seal, extend the service life, and the construction process is simple without adding too many construction links. It is a kind of road maintenance equipment that has become quite popular in recent years.

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.

How to reduce the energy consumption of emulsified asphalt production equipment is a concern of many users, and is also an issue that many manufacturers attach great importance to. Therefore, today Sinoroader, as a manufacturer of emulsified asphalt production equipment, would like to take this opportunity to share with you how to reduce the production of emulsified asphalt. Equipment energy consumption method.
Since emulsified asphalt appears as a finished product in emulsified asphalt production equipment, and the outlet temperature of ordinary emulsified asphalt is about 85°C, the outlet temperature of emulsified modified asphalt is above 95°C, so there is a lot of latent heat in emulsified asphalt, but emulsified asphalt The production equipment does not make good use of them, but directly enters the finished product tank, allowing the heat to be lost at will, resulting in a waste of energy.

For users of equipment, the amount of material used is the focus of every user. We should attach great importance to this link in the production process. The following is an analysis of the amount of emulsifier used by Gaoyuan manufacturers.
When emulsified asphalt equipment is emulsifying asphalt, the asphalt temperature is better controlled at above 130°C to have better fluidity; 2. The amount of emulsifier is generally 8-14‰ of emulsified asphalt, that is, 8-14kg per ton of emulsified asphalt (asphalt content is more than 50%), and the temperature is 60-70°C. The emulsifier should be used in the middle and upper limit of the production, 10 kg per ton of emulsified asphalt, or 20 kg per ton of water (asphalt content is 50%); the amount of BE-3 emulsifier is generally 18-25‰ of emulsified asphalt, that is, 18-25kg per ton of emulsified asphalt (asphalt content is more than 50%), and the emulsifier solution temperature is 60-70°C. The emulsifier should be used in the upper and middle limits in the first production to ensure successful production. Use 24 kg per ton of emulsified asphalt, or 48 kg per ton of water (asphalt content is 50%). After the production goes smoothly, the dosage can be reduced according to actual conditions.

The engine is the source of power for the vehicle. If the synchronous sealing vehicle wants to perform normal construction operations, it must ensure that the engine is in good condition. Routine maintenance is an important means to effectively prevent engine failure. How to maintain it is determined by Xinxiang Junhua Special Vehicle Vehicles Co., Ltd. will take everyone to understand.

Emulsified asphalt is an aqueous suspension of asphalt particles with high interfacial energy. This suspension state is thermodynamically unstable and has the potential to reduce its interfacial area (i.e., through the coagulation process) to a stable state. Preventing this coagulation state (dispersion destruction) is the stabilization effect of the emulsifier protective layer. The stability of emulsified asphalt refers to the ability of asphalt particles to aggregate and cause phase separation, and also refers to the time required for emulsified asphalt to reach equilibrium. That is, the time for asphalt particles to aggregate and separate from water. How can we increase this time? How to prevent emulsified asphalt from demulsifying?

Precautions during the production of emulsified bitumen equipment. How much do you know about this information? Let’s learn more about it:
When the emulsified bitumen equipment is in production, the viscosity of the bitumen decreases with the increase of temperature. For every 12℃ increase, its dynamic viscosity decreases by about one time. During production, the base bitumen should be heated to liquid state before emulsification. In addition, in order to adapt to the emulsification capacity of the colloid mill, the base bitumen dynamic viscosity is generally controlled to be about 200cst. The lower the temperature, the higher the viscosity, which increases the burden on the bitumen pump and the colloid mill, making it difficult to emulsify; but on the other hand, in order to prevent the demulsification caused by excessive vaporization and evaporation of water in the finished product during the production of emulsified bitumen, it is impossible to heat the base bitumen temperature too high. Generally, the finished product temperature at the outlet of the colloid mill should be controlled to be less than 85℃.

Technical features of fiber sealing equipment:
1. Zero starting strong injection technology
With more than ten years of manufacturing history of asphalt spreading trucks and asphalt gravel synchronous sealing trucks, the zero-start strong spraying technology has been accumulated for many years. The combination of time-reliable hydraulic transmission components and Meitong’s control system can make the equipment instantly start from zero. Spraying starts in line, stable and reliable.
2. Duplex sealing structure

Asphalt sealant is a material specially used for road crack repair. The following is a detailed introduction to asphalt sealant:
1. Definition and composition
Asphalt sealant is a road repair material made of asphalt or modified asphalt as the base material, with a certain amount of additives and fillers added, and processed by special technology. It usually has a black or dark brown appearance and is in a solid or semi-solid form.
2. Main characteristics
High adhesion: Asphalt sealant can firmly bond to the crack wall of the road surface to form a tight sealing layer to prevent moisture and other harmful substances from invading the road surface structure.
High elasticity: It has a certain elastic recovery ability and can adapt to the expansion and contraction changes of the road surface to prevent further expansion of cracks.
Weather resistance: After special process treatment, it has good weather resistance and can maintain its stable performance for a long time.
Convenient construction: The construction operation is simple and fast, without complex construction machinery, which reduces the construction cost.
3. Scope of application
Asphalt sealant is widely used in crack repair of various asphalt pavements, including highways, urban roads, airport runways, etc. At the same time, it can also be used for the maintenance and repair of asphalt surfaces such as bridges, tunnels, and parking lots.

Each F1 track must be paved with three layers of asphalt, middle and lower, of which the lowest layer is 10 cm coarse asphalt concrete bearing layer, its flatness is less than 8 mm; In the middle is a 4 cm medium grained asphalt concrete bond layer, its flatness is less than 5 mm; The top layer uses 4 cm modified asphalt mixture as the surface wear layer, and the flatness is less than 2 mm.

The paved F1 track cannot have more than 3 points per kilometer of flatness detection, which is much higher than the highway.

Emulsified asphalt equipment is a special equipment for producing emulsified asphalt. The emulsified asphalt produced by emulsified asphalt equipment is used in many industries. I wonder how much you know about the emulsified asphalt produced by emulsified asphalt equipment. Let’s take a look at them one by one:
Slurry seal is a cold mix asphalt mixture with the advantages of aggregate and asphalt mixing. Under normal circumstances, similar graded slurry seal has a higher modulus than hot mix asphalt mixture, so it is often used to fill road rutting. The higher stability has a higher resistance to deformation. The mixture is usually composed of harder fine aggregate grading and wear-resistant aggregate with high sand equivalent, especially micro-seal and polymer-modified seal. This greatly increases the strength and integrity of the road surface. This makes the road surface have high wear resistance and excellent deformation resistance. Emulsified asphalt emulsion is also easy to use on a mobile slurry seal paver, where mixing and admixtures are used for chemical control to meet maintenance needs.

In the cold winter, the following points should be noted when using bitumen melter equipment:
