Description

Technical Field

[0001] The invention belongs to the technical field of dust treatment, and in particular relates to an environmentally friendly filtering device for dust treatment. Background Art

[0002] In the fields of mining, metallurgy, power plants and chemical manufacturing, the working environment of workers is full of a lot of dust. This dust not only harms the health of workers, but also some dusts may explode when the concentration is too high. Therefore, dust treatment equipment is usually needed to deal with this dust.

[0003] The Chinese patent with the authorization announcement number CN219502262U discloses an environmentally friendly filtering device for industrial dust, which connects the air inlet pipe with the dust outlet of the dust collecting device. After the connection is completed, the dusty air discharged by the dust collecting device enters the inside of the filter box, and then passes through the multiple filter plates inside the filter box for multi-layer filtration, thereby achieving the filtering and dust removal effect. While filtering the dust, the filter plate reciprocates and rubs the surface of the filter plate through the bristles on one side of the mobile frame, thereby shaking off the dust on the surface of the filter plate. The above device has the following disadvantages: although the above device shakes off the dust on the surface of the filter plate through the bristles, due to the unidirectional fluidity of the air in the filter box, the dust will still adhere to the surface of the filter plate again, thereby affecting the filtering effect and efficiency of the filter plate, resulting in poor dust air treatment efficiency. Therefore, it is urgent to study an environmentally friendly filtering device for dust treatment in order to solve the above problems. Summary of the invention

During use, when the roller brush component 4 cleans a filter cartridge 201, the cylindrical box 605 is directly above the filter cartridge 201. At this time, the third servo - motor 602 drives the rope - winding wheel 603 to rotate, causing the pull rope 604 to be released, so that the cylindrical box 605 slowly descends into the above - mentioned filter cartridge 201. At the same time, positive - pressure air is input into the cylindrical box 605 through the positive - pressure air supply pipe 607, causing the air - blowing holes 606 to blow the positive - pressure air onto the filter cartridge 201, accelerating the shedding of the dust on the outer wall of the filter cartridge 201, thereby further improving the cleaning effect of the filter cartridge 201.
