Description

Technical Field

[0001] The present invention relates to the technical field of cleaning tools, and in particular to a device for quickly cleaning the screen of an ash milk rotary screen and a method for cleaning the screen of an ash milk rotary screen using the device. Background Art

[0002] In order to improve the production capacity of soda ash during the production process, the concentration of ash milk needs to be increased and the amount of sand returned in the ash milk needs to be reduced. In the current soda ash production, in order to reduce the amount of sand returned in the ash milk, the method usually adopted is to add an ash milk rotary screening process after the ash dissolution machine in the ash dissolution process, and the sand returned in the ash milk is washed and filtered again through the ash milk rotary screen. However, during continuous use, the ash milk rotary screen mesh suffers from severe clogging, resulting in a reduction in the production capacity of the equipment. Secondly, the clogging on the ash milk rotary screen mesh is difficult to clean. When cleaning the clogging attached to the surface of the ash milk rotary screen mesh, due to the hardness of the clogging, there is currently no better tool for cleaning the ash milk rotary screen mesh, and manual cleaning or high-pressure cleaning can only be used.
