The first side plate 160 is connected to a first baffle 110 extending toward the second side plate 170 and tilted downward, a second baffle 120 tilted upward is arranged above the first baffle 110, a third baffle 130 is arranged between the first baffle 110 and the second baffle 120, the second side plate 170 is provided with a fourth baffle 140 parallel to the first baffle 110 and a fifth baffle 150 parallel to the second baffle 120, the first baffle 110 and the fourth baffle 140 constitute a first channel 107, the second baffle 120 and the fifth baffle 150 constitute a second channel 108, the first channel 107 is connected to the second channel 108, and the upper part of the separation box 100 is provided with a first channel 108. 07, an electrostatic eliminator 105 is arranged at the feed port 103, a discharge port 104 connected to the second channel 108 is arranged at the bottom of the separation box 100, the first baffle 110, the second baffle 120, the third baffle 130 and the first side plate 160 form an air inlet area 109, the first air port is arranged in the air inlet area 109, the first air outlet 102 is arranged at the upper part of the separation box 100 and connected to the first channel 107, the first baffle 110 includes a support frame and a detachable plate body 500 placed on the support frame, a plurality of through holes are arranged on the plate body 500, and the separation box 100 is provided with an opening 180 for taking the plate body 500 out of the box body. An electrostatic eliminator 105 is provided at the feed port 103. The material enters from the feed port 103, passes through the first channel 107 and the second channel 108, and then flows out from the discharge port 104. During this period, the airflow flows from the first air inlet 101 to the first air outlet 102 through the through holes on the plate body 500 and takes out the dust in the material, thereby separating the material from the dust. At the same time, the plate body 500 can be taken out from the opening 180, which is convenient for replacing and cleaning the plate body 500, thereby reducing the blockage of the through holes on the plate body 500 and ensuring the separation efficiency.

[0023] The support frame includes a first support frame 400 connected to the first side plate 160 and a second support frame connected to the third baffle 130.

An elastic component is provided at one end of the guide groove 410 away from the opening 180, and the elastic component includes a contact block 412 that can move along the guide groove 410. A spring 411 is provided between the contact block 412 and the end of the guide groove 410 away from the opening 180 to limit the plate body 500 from fully extending into the separation box 100. When the plate body 500 is inserted into the opening 180, it contacts the contact block 412. Under the action of the spring 411, the plate body 500 protrudes slightly outward, making it impossible for the plate body 500 to be fully inserted into the separation box 100. The part of the plate body 500 that extends out of the opening 180 provides a force point for removing the main body, thereby facilitating the removal of the plate body 500 from the separation box 100.

[0024] A sealing plate 600 capable of covering the opening 180 is disposed at one end of the plate body 500 near the opening 180, and a limiting assembly for fixing the sealing plate 600 is disposed on the separation box 100.

A sealing strip 620 is disposed on one side of the sealing plate 600 facing the opening 180. The telescopic rod is able to be extended and retracted on the separation box 100 through the spring 411 structure. When in use, the main body is pushed into the separation box 100 so that the limit hole 610 corresponds to the position of the limit rod 700, and then the limit rod 700 is inserted into the limit hole 610. At this time, the sealing strip 620 is squeezed to seal the four sides of the opening 180, thereby fixing the plate body 500 while also ensuring the sealing of the opening 180. When the plate body 500 needs to be replaced, the limit rod 700 is pulled out of the limit hole 610, and the plate body 500 pops out under the action of the spring 411 to facilitate replacement.
