[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0029] As Figure 1-2 shown, the present invention provides a technical solution: an aluminum fluoride filtering device, including a box body 1, a feed inlet 2 is arranged at the top of the box body 1, and a filter cylinder 3 that can be lifted and rotated is arranged in the box body 1.
[0030] As Figure 1-3 shown, a lifting assembly, the lifting assembly can drive the filter cylinder 3 to lift in the box body 1, the lifting assembly includes two groups of rotatable lead screws 4, the lead screws 4 are driven by an external lifting motor 5, and a liftable seat body 6 is threadedly fitted on the lead screws 4, and the seat body 6 is movably connected to the filter cylinder 3.
[0031] As Figure 3 shown, a support plate 24 is arranged at the top of the filter cylinder 3, and the support plate 24 is slidably connected to the seat body 6. The purpose of setting the support plate 24 is that it can bear the load of the filter cylinder 3.
[0032] As Figure 3 shown, a rotating assembly, which is located on the lifting assembly, the rotating assembly can drive the filter cylinder 3 to rotate horizontally, the rotating assembly includes a tooth ring 7 fixedly arranged at the top of the filter cylinder 3, and a rotating motor 8 arranged on the seat body 6, a rotating rod 9 is installed at the output end of the rotating motor 8, and a gear 10 is arranged on the rotating rod 9, and the gear 10 meshes with the tooth ring 7.
[0033] As Figure 1 shown, a stirring assembly, including a stirring motor 11 and a stirring shaft 12, the stirring shaft 12 is located inside the filter cylinder 3, and the stirring shaft 12 rotates in the opposite direction to the filter cylinder 3.
[0034] As Figure 4As shown in the figure, it includes a vibration assembly. The vibration assembly includes a sleeve 21 fixedly arranged at the bottom of a rotating rod 9. A second spring 22 is arranged inside the sleeve 21. One end of the second spring 22 is connected to a vibration rod 23. The vibration rod 23 can collide with the filter cylinder 3 during rotation, so that the filter cylinder 3 generates vibration, ensuring that the fine materials are smoothly screened out.
[0035] As Figure 1 shown in the figure, the bottom of the filter cylinder 3 is integrally formed with a first screen mesh 13 that slopes outward. The purpose of the inclined setting is to facilitate discharging.
[0036] As Figure 1 shown in the figure, a second screen mesh 14 that can jump is arranged at the bottom of the inner cavity of the box body 1. The second screen mesh 14 is located below the first screen mesh 13. The bottom of the second screen mesh 14 is connected to the inner wall of the box body 1 through a first spring 15.
[0037] As Figure 1 shown in the figure, a knocking rod 20 is arranged at the bottom of the filter cylinder 3. The knocking rod 20 can strike the second screen mesh 14 during the up and down movement.
[0038] As Figure 1 shown in the figure, a first discharge port 16, a second discharge port 17 and a third discharge port 18 are respectively opened on the box body 1. Figure 1 In the figure, the filter cylinder 3 is in the upper limit position. At this time, the first screen mesh 13 is located above the first discharge port 16, and the first screen mesh 13 is not communicated with the first discharge port 16. Similarly, the second screen mesh 14 is not communicated with the second discharge port 17 either. When the filter cylinder 3 moves downward, the channel between the first screen mesh 13 and the first discharge port 16 is slowly opened, and the materials can be discharged through the first discharge port 16 at this time. The second screen mesh 14 is the same process. The lower limit position of the filter cylinder 3 is the position where the bottom of the first screen mesh 13 is flush with the first discharge port 16.
[0039] As Figure 1 shown in the figure, a discharge pipe 19 is arranged at the bottom of the filter cylinder 3. The discharge pipe 19 penetrates through the second screen mesh 14 and can extend to the outside of the box body 1.
[0040] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
[0041] During use, coarse aluminum fluoride particles are poured into the filter cylinder 3 through the feed port 2. The stirring motor 11 is started to drive the stirring shaft 12 to rotate, so as to stir the coarse particles. At the same time, the lifting motor 5 and the rotating motor 8 are synchronously started. The lifting motor 5 drives the lead screw 4 to rotate, and then drives the seat body 6 and the filter cylinder 3 to jump up and down in the vertical direction. The rotating motor 8 drives the gear 10 to rotate, and then drives the filter cylinder 3 to rotate (in the opposite direction to the stirring shaft 12) through the meshing relationship between the gear 10 and the gear ring 7.
[0042] In this way, under the stirring action of the stirring shaft 12, the rotation of the filter cylinder 3 itself can generate centrifugal force, so that the fine materials in the coarse materials can be quickly screened out through the filter cylinder 3. Combined with the up-and-down jumping action of the filter cylinder 3 itself, the qualified fine materials can be completely screened out from the filter cylinder 3. This primary screening effect fully ensures the subsequent qualified rate.
[0043] The coarse materials in the filter cylinder 3 are directly discharged through the discharge pipe 19. The screened fine materials fall onto the first screen 13 below. The first screen 13 rotates and jumps up and down synchronously with the filter cylinder 3, so as to further screen the fine materials sufficiently to obtain sub-nanometer particles. The screened particles are discharged through the first discharge port 16. The sub-nanometer particles fall onto the second screen 14 below. During the up-and-down jumping process of the filter cylinder 3, the second screen 14 is impacted by the knocking rod 20 at its bottom, causing the second screen 14 to vibrate, so as to screen the sub-nanometer particles again. The qualified nanometer particles are discharged through the third discharge port 18, and the unqualified particles are discharged through the second discharge port 17.
[0044] In summary, the aluminum fluoride filtering device realizes the purpose of step-by-step screening by setting a multi-stage screening mechanism, and gradually obtains aluminum fluoride particles with finer particle sizes. Further, in order to ensure the qualified rate of the finished product, we set up a liftable centrifugal filtering mechanism. This filtering mechanism utilizes the centrifugal force generated by rotation and combines with the up-and-down jumping action of the filter cylinder, so that the aluminum fluoride particles can be fully screened and separated, thus ensuring the qualified rate of the finished product.
