The inner walls of each slide rail 31 are slidably connected with a vertical rod 35 for connecting a horizontal plate 36. The vertical rod 35 located on the front side is threadedly connected to the screw rod 32, and the vertical rod 35 located on the rear side is slidably connected to the auxiliary rod 34. The bottom surfaces of the two vertical rods 35 are commonly fixedly connected to the horizontal plate 36. The bottom surface of the horizontal plate 36 is fixedly connected to a brush plate 37 for pushing the silicon micropowder on the filter screen 62 to assist in filtering. The top of the horizontal plate 36 is fixedly connected to a cylinder 39 for pushing the connecting plate 381 to move. The upper part of the cylinder 39 is provided with an auxiliary component 38 for cooperating with the wave plate 75 to push the fixed frame 7 to vibrate and assist in filtering.

[0038] Specifically, the auxiliary component 38 includes a connecting plate 381 for connecting to the cylinder 39. The connecting plate 381 is fixedly connected to the cylinder 39. The front and rear sides of the bottom of the connecting plate 381 are fixedly connected with mounting plates 382 for connecting a push block 383.

[0040] Furthermore, the filter assembly 6 includes a mounting frame 61 for connecting various components. The mounting frame 61 is movably connected to the fixed frame 7 by bolts.

[0041] Working principle: When in use, the silicon micropowder is fed into the housing 1 through the feed pipe 2, and then the motor 33 is turned on. The motor 33 will drive the screw 32 to rotate, and the screw 32 will drive the vertical rod 35 connected thereto to move. The vertical rod 35 will drive the vertical rod 35 on the other side to slide along the auxiliary rod 34 through the horizontal plate 36 connected thereto. When the horizontal plate 36 moves, it will drive the brush plate 37 to push the silicon micropowder on the filter screen 62 to assist its filtration, and can clean the sieve holes on the filter screen 62 to a certain extent. When the horizontal plate 36 moves, it will also drive the auxiliary component 38 to move. The push block 383 will push the wave plate 75 when it moves horizontally. Since the wave plate 75 is uneven, the push block 383 will push the fixed frame 7 to move downward intermittently through the wave plate 75, and the spring 73 will assist the fixed frame 7 to reset, thereby causing the filter component 6 to shake, further improving the filtration efficiency.

[0042] When it is necessary to clean the impurities on the filter assembly 6, the cylinder 39 is turned on to push the connecting plate 381 upward, thereby driving the push block 383 away from the wave plate 75 through the mounting plate 382, ​​and then the pull plate 5 is opened and the motor 33 is turned on. As in the above steps, the motor 33 will drive the screw 32 to rotate, thereby driving the brush plate 37 to push the impurities out of the housing 1 through the opening of the pull plate 5.

[0043] When the filter screen 62 needs to be repaired or replaced, open the pull plate 5, then loosen the bolts between the filter assembly 6 and the fixed frame 7, pull the installation frame 61 to disengage it from the installation groove 76, and drive the slide frame 63 to disengage from the slide groove 77. When the filter assembly 6 needs to be installed, align the slide frame 63 with the slide groove 77, then install the slide frame 63 into the slide groove 77, install the installation frame 61 into the installation groove 76, and then connect the filter assembly 6 to the fixed frame 7 by bolts.
