Working principle of thermal oil heating bitumen device
A local heater is installed in the storage tank, which is suitable for bitumen storage and heating in transportation and municipal systems. It uses organic heat carrier (heat-conducting oil) as the heat transfer medium, coal, gas or oil-fired furnace as the heat source, and forced circulation by the hot oil pump to heat the bitumen to the use temperature.

The output of bitumen decanter is 6-10t/h. It adopts an automatic telescopic sealed container structure. The barrel loading method is to lift the asphalt barrel by an electric hoist and place it on the guide rail at the entrance. The hydraulic propeller forward button is activated to push the barrel into the barrel removal device. (Push and slide into the barrel), the hydraulic cylinder stroke is 1300mm, and the maximum pushing force is 7.5 tons. The bitumen decanter has beautiful appearance, reasonable and compact arrangement, and stable performance, and is suitable for production under various industrial and mining conditions.

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.

With the rapid development of our country's economy and technology, our country's road traffic conditions have also been greatly improved. However, the load capacity of vehicles is also increasing rapidly, and the number of large trucks is also increasing, which has brought huge pressure to transportation. Therefore, highway The maintenance work has gradually attracted people's attention.

In highway maintenance, the main material of slurry seal technology is emulsified asphalt, and its main functions are as follows:
First, slurry sealing technology improves the waterproofing function of the road surface. This function is inseparable from the diverse composition and small particle size of the slurry mixture. These features allow it to form a tight surface after paving. Materials with smaller particle sizes can improve the bonding degree of the original pavement to a greater extent and better prevent rain or snow from penetrating into the pavement base layer. In short, because the materials of the slurry sealing technology not only have smaller particle sizes but also have a certain gradation, the stability of the pavement base layer and soil layer is greatly improved, and the permeability coefficient of the pavement is reduced.

Certain failures cannot be avoided during the use of the asphalt mixing plant. For example, a malfunction of the cold material feeding device may cause the asphalt mixing plant to shut down. This may be due to a malfunction in the asphalt mixing plant or due to gravel or foreign matter being trapped under the cold material belt. If it is stuck, if it is a circuit failure, first check whether the motor control inverter of the asphalt mixing station is faulty and whether the line is connected or open.
