In another embodiment, it also includes an air blowing device, the air blowing device is arranged on the connecting plate, the air blowing device includes an air pump, a main air pipe, a bronchus and an L-shaped plate, and the air pump is arranged on the On the connecting plate, the air pump is connected to the bronchus through the main air pipe, the main air pipe is a flexible hose, the bronchus is installed on the L-shaped plate, and the L-shaped plate is fixedly connected with the linkage plate, Thus, the bronchi extend into the rotating filter cartridge 202 , and the bronchi include a plurality of first bronchi blowing upwards and a plurality of second bronchials blowing downwards. After the drum-type multi-layer filter device in the present invention works for a period of time, the material is easily blocked in the filter holes of the rotating filter cartridge 202 and the fixed filter cartridge 201, and the first bronchus and the second bronchus of the air blowing device The bronchus can be aligned with the filter holes of the rotating filter cartridge 202 to blow air, and the high-pressure airflow can also blow air through the filter holes of the fixed filter cartridge 201 through the rotating filter cartridge 202, thereby blowing the filter holes through the high-pressure gas. After the material is filtered, the air pump is turned on, and the high-pressure gas is ejected through the bronchus, while the rotating filter cartridge 202 continues to idle, and the rotating filter cartridge 202 can be filtered through the first bronchus and the second bronchus. Cartridge 202 and the filter holes of the fixed filter cartridge 201 in the circumferential direction are blown to remove impurities, and at the same time, because the bronchus is installed on the linkage plate through the L-shaped plate, the first bronchus and the second bronchus Driven by the threaded tube, the linkage plate can move back and forth in the horizontal direction, so as to blow air and remove impurities in the filter holes in the axial direction of the rotating filter cartridge 202 and the fixed filter cartridge 201 .

Working principle: when in use, the material is put into the feeding port 43 and conveyed to the rotating filter cartridge 202 through the screw conveying blade 42, and the material in the rotating filter cartridge 202 is tumbling by rotating the rotating filter cartridge 202 to realize the first filtration. The final material slides between the fixed filter cartridge 201 and the rotating filter cartridge 202, and the rotation of the rotating filter cartridge 202 will drive the four stirring plates 205 to rotate to roll the materials between the fixed filter cartridge 201 and the rotating filter cartridge 202, so as to speed up the fixed filtration process. The filtration rate of the material by the cylinder 201, the material after multiple filtrations will slide to the bottom of the screening box 1, when the materials in the fixed filter cylinder 201 and the rotating filter cylinder 202 need to be collected, the rotating and rotating filter cylinder 202 will make the The slide block 212 moves to the position corresponding to the moving slide rail 38, the rotating threaded pipe 32 drives the threaded rod 35 to move, the threaded rod 35 moves to drive the linkage plate 36 to move, and the linkage plate 36 moves through the moving slide rail 38 and the baffle plate 39 respectively Drive the first drawing plate 207 and the second drawing plate 210 away from the screening box 1, so that the bottom of the fixed filter cartridge 201 and the rotating filter cartridge 202 are opened, so that the materials in the fixed filter cartridge 201 and the rotating filter cartridge 202 slide down to the screening The bottom of the box 1 completes the collection of the materials in the fixed filter cylinder 201 and the rotating filter cylinder 202. Through this linkage mechanism, the material is effectively prevented from being squeezed and the filter hole is blocked by the material, thereby reducing the filtering effect of the filter and screening cylinder.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection of the present invention. within range.
