[0010] By adopting the above technical scheme, the main function of the vacuum pump is to extract gas from the high-pressure area to the low-pressure area. In applications such as air purification, gas detection, and vacuum technology, the vacuum pump can help to achieve gas extraction and processing. The filters are primary filter and HEPA filter.

The rotating stirring rod can fuse the material inside the mixing box. The spiral blade installed on the outer side of the bottom of the stirring rod can make the material at the bottom be output upward due to the spiral blade design, thereby achieving a sufficient stirring and fusing effect on the material accumulated at the bottom.

[0017] Preferably, a material discharge port is provided on the outside of the mixing box of the mixing mechanism, and a baffle is slidably connected to the outside of the material discharge port.

[0023] Preferably, support columns are fixedly mounted on the bottom of the mixing box of the mixing mechanism and the bottom of the filtering box of the filtering mechanism respectively.

[0024] By adopting the above technical solution, the support columns respectively fixed to the bottom of the mixing box and the bottom of the filter box can disperse the load, increase the load-bearing capacity of the parts, and ensure that the parts will not be deformed due to pressure.

[0046] Working principle: the material to be mixed enters the feeding mechanism 2 through the inlet 1. The material entering the feeding mechanism 2 passes through the first support frame 22 fixed on the inner wall of the feeding box 21. The first servo motor 23 fixed on the end face of the first support frame 22 drives the rotating dispersion plate 24 fixed on the output end to rotate.

[0049] The material entering the mixing mechanism 3 is connected to the output end of the second servo motor 32 inside the mixing box 31 by rotation. The second servo motor 32 drives the stirring rod 33 fixed at the output end to rotate. The rotating stirring rod 33 can fuse the material inside the mixing box 31. The spiral blade 34 installed on the outer side of the bottom of the stirring rod 33 can make the material at the bottom output upward due to the design of the spiral blade 34, so that the material accumulated at the bottom is fully stirred and fused. The top of the stirring rod 33 is rotatably connected to the second support frame 35. The second support frame 35 plays the effect of effectively fixing the working position of the stirring rod 33.
