1. Working principle of vacuum cleaner truck:
The working principle of the vacuum cleaner truck is actually very simple. It is the same as an ordinary vacuum cleaner. Ordinary vacuum cleaners have a motor, a vacuum bucket, and a filter screen.
The vacuum cleaner truck corresponds to a sub-engine, a vacuum box and eight filter cartridges. The auxiliary engine of the vacuum vehicle provides power to drive the fan to rotate, and the fan draws out the air in the vacuum box to form a negative pressure suction cup and connects the vacuum box with a hose to suck up ground garbage.
The vacuum cleaner truck is different from the road sweeper and the sweeper. It is equipped with a dust filter bucket inside the dustbin.
This design is the essence of the vacuum cleaner, and it determines the specificity of the vacuum cleaner. Because of the dust filter system, the vacuum vehicle can adapt to the cleaning environment with a large amount of fine dust.
2. Functional structure of vacuum cleaner truck:
- The vacuum cleaner truck adopts the principle of negative pressure pure suction, one-way air intake (no back-blowing air flow), to achieve dust only in and out, no dust, and achieve PM2.5 zero emission. It is suitable for the mechanized cleaning operation of cement concrete pavement and asphalt pavement such as urban roads, viaducts, squares, airports, docks, factories, etc.
- The center-mounted wide suction nozzle is composed of main suction + left and right suction nozzles. The left and right suction nozzles also have the function of collision avoidance.
- The wide suction nozzle is lifted and lowered by a hydraulic cylinder, and the use of hydraulic floating technology can greatly increase the service life of the rubber wheel
- With a unique box structure, the filter cartridge is simple and convenient to disassemble and maintain. The garbage bin adopts an inclined plate structure, which is convenient for unloading without manual intervention.
- The circular filter cartridge is equipped with an air pulse filter cartridge dust removal device, which can effectively separate the dust on the dust collector’s filter cartridge, avoiding the blockage and secondary pollution of the filter cartridge, thereby greatly improving the life of the filter cartridge and dust collection The overall performance of the vehicle greatly improves the dust removal effect of the filter cartridge; the large-capacity trash can is configured to improve the work efficiency.
- The electrical system adopts integrated modular control, and the panel has video functions such as fault diagnosis, digital test, real-time display and monitoring of auxiliary engine speed, water temperature, operating conditions, etc., and the operating status is clear at a glance and easy maintenance.
