Description

Technical Field

[0001] The utility model relates to the technical field of metallurgy, in particular to an automatic dust cleaning system for the surface of a vehicle. Background Art

[0002] In the daily production of the metallurgical industry, there are many vehicles transporting metallurgical raw materials. When the rear eight-wheeled mining truck transports the ore mud, most of them directly use excavators to dig the ore mud and then load it into the mining truck for loading. During the loading process, the dust and fine particles generated by the dry ore mud will adhere to the surface of the vehicle body, and the ore mud on the tires will be sprinkled on the road during the transportation of the vehicle, causing the dust on the vehicle body to be blown into the air and on the road with the wind, which has a great impact on the company's production environment. In addition, when it rains, the ore mud left on the road is easy to slip, which is easy to cause traffic accidents, and it is very difficult to clean. For this kind of cleaning, the conventional practice is to use a water gun to wash the road surface or fog cannons and other equipment to clean and reduce dust. Some metallurgical factories also use simple car washers for cleaning. Due to the large number of vehicles, special personnel are required to clean, the silt on the ground flows everywhere, the waste of water resources is also relatively large, and the cleaning is not clean, which is time-consuming and laborious.

[0003] Therefore, the utility model provides a vehicle surface dust automatic cleaning system for fully automatically cleaning fine mineral mud dust on the vehicle body surface. Utility Model Content

[0012] Furthermore, an automatic flushing nozzle for flushing sediment in the channel is provided inside one end of the channel. A flushing pump connected to the input end of the automatic flushing nozzle is set with an automatic operation interval. When the set time is reached, the flushing pump starts to operate, and the sludge and the like settled on the bottom of the channel are flushed by the water flow sprayed from the automatic flushing nozzle.
