Description

TECHNICAL FIELD

[0001] The utility model relates to a dust recovery device for mineral processing. BACKGROUND

[0002] Minerals often need to be crushed for subsequent extraction when producing related metal ingots. A crushing device is needed during crushing. Since some minerals are rare, there are a few rare elements in the dust generated during actual crushing. The dust needs to be recovered.

[0003] A dust recovery device for mineral processing is disclosed in Chinese patent CN220195875U, with an application date of June 13, 2023. This device collects dust generated during mineral processing in two ways. One way is to set a suction port on the top of the mineral processing device. The dust generated during processing is sucked by the suction port in the air, filtered by the filter plate and collected in the cloth bag. The other way is to use a dust collector connected by a flexible hose to suck the dust scattered on the ground, which is also collected in the cloth bag. The cloth bag uses a pull-out structure, which is convenient for replacing the cloth bag and recycling the dust collected in the cloth bag. However, the filter screen used in the above device filters the dust, which quickly spreads over the surface of the filter screen, affecting the filtering effect. If the filter screen is removed and cleaned, it is too troublesome and needs to be cleaned frequently. Therefore, the present inventor provides a dust recovery device for mineral processing to solve the problems in the background technology. SUMMARY

[0004] The purpose of the utility model is to provide a dust recovery device for mineral processing, which can automatically clean the surface of the filter screen.

When the ore processing device is used, a large amount of ore dust will be splashed, and the ore dust can be recycled. Therefore, the negative pressure fan can be started through an external power supply. The input end of the negative pressure fan sucks the air in the cavity above the treatment box through the connecting pipe, so that the treatment box is in a negative pressure state and the ore dust and external air are sucked through the dust inlet pipe, the folding pipe and the dust suction box. The ore dust is blocked by the filter cartridge after entering the inside of the treatment box, and the air is discharged through the connecting pipe.
