Technical Field

[0001] The utility model relates to the technical field of agricultural drying and dust removal, and specifically relates to an automatic dust removal filter screen. Background Technique

[0002] Grain drying is an important post-treatment process for agricultural products. The main purpose is to reduce the moisture content in the grain to prevent mildew, extend the storage time and maintain the grain quality. Grain dust will be generated during the grain drying process. The commonly used filter screens are industrial filter screens composed of physical nylon filter screens and stainless steel support skeletons. The grain dust will adhere to the outer side of the filter screen and block the filter holes, which requires manual disassembly and cleaning, consuming time and effort. Secondly, the disassembly and installation steps of the filter screen outside the stainless steel support skeleton are cumbersome, increasing the cleaning workload and resulting in low cleaning efficiency. In view of the above problems, the inventor proposes an automatic dust removal filter screen to solve the above problems. Content of the Utility Model
