Abstract
Description
Technical fields:
[0002] This utility model belongs to the technical field of conveyor belt cleaning and mineral powder recovery equipment, and more specifically relates to a cleaning type washing and dust removal device. Background technology:
[0004] After use, belts are usually cleaned to extend their service life. However, existing cleaning and dust removal boxes can only clean the dust on the belt surface through a single cleaning structure, so the belt is difficult to clean thoroughly, resulting in belt damage and corrosion, and waste of transported materials.
[0005] The utility model patent with patent number 202323340654.2 discloses a belt cleaning box. By setting up a scraper, the adhesive material on the surface of the belt is scraped off during the belt return process, and the material falls into the collection box. By setting up a cleaning pipe, water or gas is introduced into the cleaning pipe to clean or blow away the belt, making it easier for the material adhering to the belt to fall off; thus, the above problems are effectively solved.
[0006] However, the residual mineral powder adhering to the conveyor belt generally has recycling value, especially when the mineral powder contains high-value metals (such as copper and lithium) or can be used as building material raw materials, the recycling benefits are significant. Existing cleaning and dust collection boxes only clean the carbon powder adhering to the surface of the conveyor belt and then discharge it immediately after cleaning, resulting in a waste of resources. Utility Model Content:

[0027] The beneficial effects of this utility model are:
[0028] One advantage of this invention is the inclusion of a coal powder recovery filter plate and a brush that moves back and forth along the filter plate. This allows the mineral powder adhering to the conveyor belt swept down by the cleaning component to be intercepted and filtered. At the same time, the brush cleans the mineral powder on the coal powder recovery filter plate and pushes it into the coal powder recovery boxes at both ends. The powder is then collected in the recovery boxes through the recovery port. Furthermore, the filter plate can be thoroughly cleaned by the reciprocating drive component, effectively preventing mineral powder from accumulating and clogging the filter plate, and ensuring solid-liquid separation efficiency.
