Description

A high-efficiency and energy-saving cleaning system for floor washing vehicles

technical field

Background technique

Dust pollution directly threatens people's lives, especially living in a dust-polluted environment can cause a variety of cardiovascular and respiratory diseases. Dust pollution has the greatest impact on the elderly and children, and too much dust is easy to breed germs and viruses, which is extremely harmful to health, and it will also have great harm to skin health. Sweeping and dust removal measures are usually used to remove dust pollution and other garbage deposited on the road surface. Sweeping vehicles usually have the dual functions of suction and sweeping, and are the main tool for modern road cleaning. At the same time, the sweeper is a complex device integrating water source, power supply and gas source. Existing sweeping vehicles usually use wide suction nozzles with rear high-pressure spray booms to clean the road surface. The water flow of the rear high-pressure spray booms overlaps linearly. After cleaning, the sewage is recovered through the suction ports. The overlapping parts of the high-pressure spray booms are easy to form obvious water marks. , the dirty water mark is more obvious after the blockage, and the suction port cannot pass through the rear part of the suction port, and if there is oil on the road surface, it cannot be cleaned, and the sewage cannot be recycled, resulting in waste of water resources and short continuous operation time.
