[0032] The pressing assembly includes a fixing plate 3, which provides support. The fixing plate 3 is fixedly connected to the top of the support frame 5. The inner wall of the fixing plate 3 is provided with a slide groove 36, which provides support for the support block 35 to slide and provide support.

[0033] Reference Figure 1 , Figure 3 A limit assembly is provided on the inner wall of the filter screen 9, and the limit assembly includes a card plate 7, which supports a limit rod 12 and a spring 24. The card plate 7 is fixedly connected to the front surface of the feed hopper 8, and the front surface of the card plate 7 passes through and is slidably connected to the limit rod 12. The limit rod 12 slides into the limit groove 11 to limit the limit block 10 and limit the filter screen 9 at the same time. The limit rod 12 is elastically connected to the card plate 7 through the spring 24. When the limit rod 12 is pulled out of the limit groove 11, the spring 24 can be stretched and the limit of the limit block 10 can be released. At the same time, when the filter screen 9 is installed, the limit rod 12 can be reset and slide into the limit groove 11 by the reverse force of the stretching spring 24 to limit the filter screen 9.

[0034] Furthermore, a limiting rod 12 passes through and is slidably connected to the front surface of the feed hopper 8 near the top of the filter screen 9. The top of the filter screen 9 is fixedly connected to a limiting block 10. The limiting block 10 cooperates with the limiting groove 11 and the limiting rod 12 to limit the filter screen 9. The front surface of the limiting block 10 is provided with a limiting groove 11. The limiting rod 12 is inserted into the inner wall of the limiting groove 11, which can cooperate to limit the filter screen 9.

The filter screen 9 is clamped at the bottom end of the clamping block 6. The filter screen 9 can be taken out by moving the filter screen 9 to slide out of the bottom end of the clamping block 6, which is convenient for cleaning the filter screen 9, thereby improving the subsequent processing of silicon micropowder and improving the processing quality.

[0035] Reference Figure 1 - Figure 3 The inner wall of the slide groove 36 is slidably connected with a support block 35, and the front surface of the support block 35 is fixedly connected with a guide block 31, the support block 35 supports the guide block 31, and the guide block 31 is slidably connected to the front surface of the fixed plate 3, and the guide block 31 is elastically connected to the support frame 5 through a spring 34. By pressing the pressure plate 32, the guide block 31 can be driven to move and squeeze the spring 34. At the same time, the reverse force of the spring 34 can drive the guide block 31 and the pressure plate 32 to reset. The front surface of the guide block 31 is fixedly connected with a pressure plate 32, and the pressure plate 32 can drive the pressure rod 33 to move downward. The bottom end of the pressure plate 32 is fixedly connected with a pressure rod 33 and multiple groups are provided.

[0036] Working principle: When in use, the guide block 31 and the support block 35 are driven to move by pressing the pressure plate 32 downward, and the support block 35 slides in the slide groove 36 to provide support, and the spring 34 is squeezed downward by the guide block 31, and the pressure rod 33 is driven to move downward by the pressure plate 32. At the same time, the pressure rod 33 is aligned with the through hole at the top of the filter screen 9 below, so that the pressure rod 33 moves to squeeze and disperse the silicon micropowder that is difficult to be vibrated and accumulated on the filter screen 9. After the accumulated silicon micropowder that is difficult to be vibrated is dispersed by the cooperation of multiple groups of pressure rods 33, it is sieved through the filter screen 9 and enters the drying box 1 for processing, thereby preventing the silicon micropowder from accumulating and improving the silicon micropowder. The processing efficiency is improved. When the processing is completed, the spring 24 can be stretched by pulling the limit rod 12, so that the limit rod 12 slides out of the limit groove 11 to release the limit block 10. At this time, the limit block 10 can be pulled to drive the filter screen 9 to move and slide out of the bottom end of the block 6, and the filter screen 9 can be removed for cleaning, thereby improving the quality of subsequent silicon micropowder processing. When the cleaning is completed, the filter screen 9 can be stuck into the bottom end of the block 6, and the limit rod 12 can be pulled to cooperate with the reverse force of the spring 24 to reset the limit rod 12 and slide into the limit groove 11 to limit the limit block 10, so as to complete the installation of the filter screen 9, thereby improving the installation efficiency.
