[0002] During the cement production process, the air will contain a large amount of dust, which will cause physical harm to the workers and pollute the environment. Therefore, the dust needs to be processed and collected.

[0003] When the existing dust removal device cleans the collected cement dust, in order to prevent the collected dust from overflowing, it is usually necessary to turn off the fan for processing. For example, the utility model patent with application number CN202321269466.2 discloses a dust removal device for clean cement production. When cleaning the dust inside the dust collector casing, if the dust suction fan is not turned off, the external airflow will enter the dust collector casing through the exhaust pipe, affecting the discharge and cleaning of the dust. If the fan is turned off, the dust in the air cannot be processed during the dust discharge and cleaning time, which reduces the dust removal efficiency. In addition, the dust removal device is not convenient for cleaning the dust adhered to the dust filter cartridge. The filtering effect will be reduced when used for a long time, which has certain disadvantages. Utility Model Content
