Description

Technical Field

[0001] The utility model belongs to the technical field of chemical filtering devices, and in particular relates to a filtering device. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] When feeding the raw materials of powdered chemicals, it is necessary to intercept and filter out some crystallized or sticky materials, because the agglomerated raw materials cannot be used and need to be reprocessed and separated before they can be used again. Filtering can be done during the feeding process. Based on the above, the filtering device currently used mainly adopts the principle of filter screen interception to filter the agglomerates in the powdered raw materials, but long-term use of too many agglomerates will cause blockage or obstruction, affecting the passage of the raw materials, and it is inconvenient to continuously remove the filtered materials.

[0004] In the prior art, Chinese utility model patent CN208032046U discloses a conveyor belt type filter device, in which when the motor drives the conveyor filter belt to rotate, the scraper scrapes the impurities on the surface of the conveyor filter belt into the receiving hopper, so that the filter holes remain unobstructed, thereby improving the filtering efficiency of the filter device; however, the structure of the device has the following problems, when the material has a certain viscosity, the scraper will enter the filter holes under the action of the scraper during the process of scraping the surface of the filter belt, causing the filter holes to be blocked. Therefore, the above structure still needs to disassemble and clean the filter plug after a period of time, and still cannot solve the problem of filter hole blockage. Utility Model Content

[0005] The utility model aims to provide a filtering device to solve the problem that the existing filtering device mentioned above mainly adopts the principle of filtering the agglomerates in the powdered raw materials by intercepting the passage of the filter screen, but too many agglomerates intercepted after long-term use may cause blockage or obstruction, thus affecting the passage of the raw materials and making it inconvenient to continuously remove the filtered materials.
