Dust removal device

Abstract

The invention belongs to the technical field of dust removal equipment, and discloses a dust removal device. The dust removal device is arranged on a top plate, and comprises a filter device installing plate, a rotating shaft, a driving device, an upper skew gear and a lower skew gear, wherein the driving device drives the rotating shaft to rotate; the upper skew gear and the lower skew gear are mutually engaged; the upper part of the rotating shaft passes through the top plate; the upper part of the rotating shaft is provided with upper screw threads and lower screw threads in a way of respectively corresponding to the upper side and the lower side of the top plate; a conical roller bearing is arranged between the upper screw threads of the rotating shaft and the top plate; the outer circle of the conical roller bearing is fixed to the top plate; an upper locking screw nut is assembled on the upper screw threads; a plane bearing is arranged between the lower screw threads of the rotating shaft and the top plate; the outer circle of the plane bearing is fixed to the top plate; a lower locking screw nut is assembled on the lower screw threads. The upper skew gear is fixedly arrangedon the filtering device installing plate; the lower part of the rotating shaft passes through the filtering device installing plate and the upper skew gear; a position between the rotating shaft andthe filtering device installing plate is sealed; the lower skew gear is fixed on the lower end of the rotating shaft; at least one guide post is arranged on the filtering device installing plate; a slide sleeve slidingly matched with the guide post is arranged on the top plate.

Description

technical field [0001] The invention belongs to the technical field of dust removal equipment, and in particular relates to a dust removal device. Background technique [0002] During the production and processing of existing metal workpieces, some workpieces need to be subjected to a surface treatment process such as shot blasting in a shot blasting machine. When the shot blasting machine is working, a large amount of dust will be generated when the projectile hits the surface of the workpiece. In order to ensure the safety of the operator's working environment, a dust removal device is often used to filter the dusty gas in the shot blasting machine. It is easy to accumulate on the dust removal device and the filter element needs to be replaced frequently, which causes inconvenience to production and processing. Contents of the invention [0003] The present invention aims at the deficiencies in the above-mentioned prior art, and provides a dust removal device capable of...
