DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1~Figure 5 As shown, this embodiment proposes to include:

[0028] A processing box 1, a feeding hopper 26 with a flip cover is embedded in the top of the processing box 1, the flip cover is opened, and the fluorite powder to be processed is introduced into the processing box 1 from the feeding hopper 26;

[0029] A filter frame 2 is connected to the inner wall of the treatment box 1. The filter frame 2 is tilted. A filter screen 3 for filtering the fluorite powder is connected to the top of the filter frame 2.

[0030] The two vertical inner walls of the processing box 1 are connected to the hollow plate 5 through multiple connecting blocks 4. The inner cavity of the hollow plate 5 is provided with a movable plate 6. The bottom end of the hollow plate 5 is connected to a connecting plate 7. Multiple springs 8 are connected between the connecting plate 7 and the movable plate 6. The design of the spring 8 prevents the rotation of the eccentric wheel 10 from damaging the filter screen 3, thereby protecting the filter screen 3. The movable plate 6 is rotatably connected to multiple rotating rods 9 with the same inclination angle as the filter frame 2. The outer periphery of the rotating rod 9 is connected to an eccentric wheel 10 for improving the filtration efficiency. The outer periphery of the movable plate 6 is equipped with multiple dust-proof motors 11 for providing power to the rotating rod 9. The fluorite powder falls onto the filter screen 3 of the filter frame 2. At this time, the dust-proof motor 11 drives the rotating rod 9 to rotate, so that the eccentric wheel 10 intermittently excites the filter screen 3, thereby improving the filtration effect of the filter screen 3, and finally the fluorite powder falls into the gas gathering frame 13 along the filter screen 3.

[0031] A storage passage for the filter frame 2 to pass through is opened on the side of the processing box 1, and an inclined baffle 12 is connected to the inner wall of the processing box 1 away from the storage passage.

[0032] A gas gathering frame 13 corresponding to the position of the storage channel is installed on the side of the processing box 1, and multiple first fans 14 are installed on the inner wall of the gas gathering frame 13. The air blowing of the first fans 14 prevents dust from flowing out of the gas gathering frame 13. The height of the first fans 14 ensures that the fluorite powder will not be affected when unloading.

[0033] The top of the processing box 1 is connected to the installation barrel 16 through multiple connecting rods 15. The top and bottom of the installation barrel 16 are respectively installed with a second fan 17 and a sealing plate 18. The sealing plate 18 is connected to the processing box 1 through multiple ventilation pipes 19. The second fan 17 blows air and the auxiliary ventilation pipes 19 blow air downward to improve the filtration effect of the filter screen 3.

[0034] A dustproof frame 20 is embedded in the side of the processing box 1 away from the storage channel, and the inner wall of the dustproof frame 20 is connected to a dustproof net. Two linear motors 21 with dustproof function are installed on the inner wall of the processing box 1, and a cleaning brush 22 for cleaning the dustproof net is connected between the two linear motors 21. The inner wall of the processing box 1 is connected to an inclined auxiliary frame 23 corresponding to the position of the dustproof frame 20, and a plurality of third fans 24 are installed on the inner wall of the auxiliary frame 23. The inner wall of the auxiliary frame 23 is connected to a spray device 25 for dust reduction. The exhaust of the third fan 24 assists the air in the processing box 1 to enter the auxiliary frame 23, and the spray device 25 carries out dust reduction.

[0035] The first fan 14, the second fan 17 and the third fan 24 have the same wind direction.

[0036] This application is for a dusty environment, and all structures and instruments are dust-proof and dust-resistant, and undergo regular maintenance to ensure that the work is carried out safely.

[0037] In this embodiment, the flip cover is opened, and the fluorite powder to be processed is introduced from the feeding hopper 26 into the processing box 1, and falls on the filter screen 3 of the filter frame 2. At this time, the dustproof motor 11 drives the rotating rod 9 to rotate, so that the eccentric wheel 10 intermittently excites the filter screen 3, thereby improving the filtration effect of the filter screen 3, and finally the fluorite powder falls into the gas gathering frame 13 along the filter screen 3;

[0038] During this process, the first fan 14, the second fan 17 and the third fan 24 blow air. The first fan 14 blows air to prevent dust from flowing out from the air gathering frame 13. The second fan 17 blows air downward through the auxiliary ventilation pipe 19 to improve the filtration effect of the filter 3. The third fan 24 exhausts air from the auxiliary treatment box 1 into the auxiliary frame 23 and is subjected to dust reduction by the spray equipment 25.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
