Description

Technical Field

[0001] The utility model provides a cement mill dust removal device for a cement production line, and relates to the field of dust removal devices. Background Art

[0002] Cement mill is the key equipment for crushing materials after they are broken. Cement mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, glass and ceramics and other production industries to grind various ores and other grindable materials by dry or wet method.

[0003] In cement production lines, the exhaust gas from cement grinding systems can only be discharged after being treated by the dust removal device of the cement grinding system. Most existing dust removal devices use bag dust collectors. When the bag dust collector is in use, after a period of time, a lot of dust adheres to the bag. It is necessary to use a blowing device to blow a large amount of air into the inside of the bag to make the bag expand and deform and shake off the dust. However, the back-blowing method has the problem of poor cleaning effect of the bag. Some dust adheres firmly and is not easy to fall off. For this reason, we propose a cement production line cement grinding dust removal device. Utility Model Content

[0010] Preferably, the fixing rod is fixed between the mounting sleeve and the fixing ring.

[0011] Beneficial effects of the utility model:

[0012] Through the setting of the shaking component, the bag body can be driven to shake when the bag dust collector is in normal use and during dust removal and backblowing. Therefore, when the bag dust collector is in normal use, dust can be continuously shaken off to prevent dust from adhering and accumulating on the surface of the bag body, thereby extending the interval of backblowing dust removal of the bag body. During backblowing dust removal, the dust can also be shaken off by continuously shaking the bag body, thereby improving the dust removal effect. BRIEF DESCRIPTION OF THE DRAWINGS
