2results about How to "Stable dust removal" patented technology

The utility model discloses a dust removal device under a mine, and relates to the technical field of dust removal equipment in the mine. The device comprises a dry-type dust collector which is arranged in a mine, an air outlet of the dry-type dust collector is located at an air outlet of the mine, an air inlet of the dry-type dust collector is connected with an air pipe, a hanging bracket is installed at the free end of the air pipe, the two ends of the hanging bracket are respectively provided with a back shore supporting foot, the hanging bracket is provided with two sections, and the two sections of the hanging bracket are connected through a telescopic assembly. And one end of the supporting arm assembly is rotationally connected with the hanging bracket, the other end of the supporting arm assembly is rotationally connected with a positive pressure fan, and an air outlet of the positive pressure fan corresponds to an air inlet of the air pipe. According to the utility model, the two telescopically connected hanging brackets are connected through the telescopic assembly, so that the length can be adjusted according to the caliber change of different areas of a mine; the supporting arm assembly moves to the side far away from the air pipe, dust is blown to the air pipe, the dust removal rate is increased, and the air quality in a mine and the operation safety of miners are guaranteed.

This utility model relates to the field of dust collector bag technology, specifically a dust collector bag that is easy to connect and fix. It includes a bag body fitted onto a bag frame. The bag body is characterized by a steel wire ring at its top, and multiple sets of rubber strips fixed to the inner wall of the bag body, with grooves on the surface of the rubber strips. The beneficial effect is that by integrally forming a cloth cover around the top of the bag body, and setting steel wire rings on the top and bottom surfaces of the inner wall of the cloth cover, during installation, after fitting the bag body onto the bag frame, pulling downwards causes the cloth cover to fit over the top of the frame. Using pliers, the steel wire rings are twisted through the cloth cover, tightly securing them to the top ring of the bag frame. Simultaneously, the rubber sleeve on the inner ring of the cloth cover increases the friction between it and the top ring of the frame, further strengthening the connection and effectively preventing the bag body from falling off during use, ensuring stable dust collection.
