[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] Example 1, by Figure 1 , Figure 2 and Figure 3 The present invention includes a screening box body 1, a diversion plate 2 is provided inside the screening box body 1, a first discharge hopper 3 and a second discharge hopper 4 adapted to the diversion plate 2 are fixedly connected to both sides of the screening box body 1, and an angle adjustment component adapted to the diversion plate 2 is installed on the screening box body 1.

[0037] Two side plates 5 are arranged above the diversion plate 2. Several screens 6 are arranged obliquely between the two side plates 5. Support rings 15 are fixedly fitted around the screens 6. The side plates 5 are equipped with a flipping cleaning structure adapted to the support rings 15. The screening box body 1 is equipped with a vibration mechanism adapted to the two side plates 5. A third discharge hopper 7 and a feed hopper 8, adapted to the side plates 5, are fixedly connected to both sides of the screening box body 1. The flipping cleaning structure drives the support rings 15 and screens 6 to flip 180 degrees, so that the side of the screens 6 with material blockage faces downwards. An angle adjustment component drives the diversion plate 2 to rotate, so that the lower end of the diversion plate 2 faces the first discharge hopper 3. The vibration mechanism... The drive side plate 5 and the screen 6 vibrate relative to the screening box body 1, causing the material blocked on the screen 6 to fall onto the diversion plate 2. The cleaned material rolls down through the diversion plate 2 onto the first discharge hopper 3 and is discharged through the first discharge hopper 3. After the screen 6 is cleaned, the angle adjustment component drives the diversion plate 2 to rotate in the opposite direction to the initial position so that the lower end of the diversion plate 2 faces the second discharge hopper 4. The material to be screened can then be added back into the screening box body 1 through the feed hopper 8, and the next round of material screening can begin. This facilitates the screening of fluorite concentrate without the need for repeated disassembly and reassembly of the screen 6. The cleaning of the screen 6 can be completed inside the screening box body 1, improving convenience.

[0038] Example 2, based on Example 1, is... Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The tilting and cleaning structure includes a movable frame 9 disposed within the screening box body 1, side plates 5 located below the movable frame 9, and a pushing unit adapted to the movable frame 9 mounted on the side plates 5. Several baffles 10 are disposed between the two side plates 5, and the baffles 10 and the movable frame 9 are fixedly connected by several connecting columns 11. The bottom of each baffle 10 contacts the top of two adjacent support rings 15. An inclined surface for guiding material is provided on each baffle 10. A tilting component adapted to the support rings 15 is mounted on each side plate 5. The pushing unit includes a support part 12 fixedly mounted on the side plate 5, and a first hydraulic telescopic rod 13 fixedly mounted on the support part 12. The telescopic end of the first hydraulic telescopic rod 13 and the movable frame 9 are fixedly connected by a first connecting plate 14. The tilting component includes a first rotating shaft 16 fixedly mounted on both sides of the support rings 15. The first rotating shaft 16 passes through the corresponding side plate 5 and is rotatably connected to the side plate 5. Sliding seats 18 are respectively provided on the opposite sides of the two side plates 5. A plurality of mounting seats 20 are fixedly installed on the 5. A second hydraulic telescopic rod 21 is fixedly installed on the mounting seat 20. The telescopic end of the second hydraulic telescopic rod 21 and the sliding seat 18 are fixedly connected through a second connecting plate 22. A mesher adapted to the sliding seat 18 is installed on the first rotating shaft 16. A plurality of guide sleeves 23 are provided on the outer sliding sleeve of the sliding seat 18. The guide sleeves 23 are fixedly connected to the side plate 5. The mesher includes a gear 17 fixedly installed on the end of the first rotating shaft 16 away from the support ring 15. A plurality of toothed plates 19 are fixedly installed on the sliding seat 18. The gear 17 and the corresponding toothed plates 19 mesh with each other. The vibration mechanism includes a plurality of vibration motors 24 respectively fixedly installed on the side of the two side plates 5 away from each other. A plurality of first fixing plates 25 are fixedly connected on the side of the two side plates 5 away from each other. A second fixing plate 26 is provided below the first fixing plate 25. The second fixing plate 26 is fixedly connected to the inner wall of the screening box body 1. The second fixing plate 26 and the first fixing plate 25 are connected by a plurality of first springs 27.

[0039] The baffle plate 10 blocks the connection between two adjacent support rings 15 to prevent material from rolling into the gap between the two support rings 15. When it is necessary to drive the support rings 15 and the screen 6 to rotate 180 degrees, the first hydraulic telescopic rod 13 drives the first connecting plate 14 and the movable frame 9 to move relative to the side plate 5. The movable frame 9 drives the baffle plate 10 to move relative to the support rings 15 through the connecting column 11, so that the baffle plate 10 no longer contacts the support rings 15, avoiding interference with the rotation of the support rings 15 and the screen 6. Then, the second hydraulic telescopic rod 21 drives the second connecting plate 22 and the sliding seat 18 to move, and the sliding seat 18 moves relative to the guide. The guide sleeve 23 and the side plate 5 slide. The design of the guide sleeve 23 allows the sliding seat 18 to move smoothly relative to the side plate 5. The sliding seat 18 drives the gear 17 and the first rotating shaft 16 to rotate through the toothed plate 19. The first rotating shaft 16 can drive the support ring 15 and the screening screen 6 to flip. Through the design of the first fixed plate 25, the second fixed plate 26 and the first spring 27, the side plate 5 is elastically connected relative to the screening box body 1. The vibration motor 24 is started. The vibration motor 24 drives the screening screen 6 and the first fixed plate 25 to vibrate relative to the second fixed plate 26 and the screening box body 1, so that the material rolls on several screening screens 6 and is screened through the screening screens 6.

[0040] Example 3, based on Example 1, is... Figure 1 , Figure 2 , Figure 7 and Figure 8 The angle adjustment assembly includes movable seats 28 symmetrically arranged on both sides of the diversion plate 2. Second rotating shafts 29 are fixedly connected to both sides of the diversion plate 2, and the second rotating shafts 29 and corresponding movable seats 28 are rotatably connected. The screening box body 1 is equipped with guide members that cooperate with the movable seats 28. Two movable plates 33 are symmetrically arranged below the diversion plate 2. Several third hydraulic telescopic rods 34 are fixedly connected to the bottom of the screening box body 1. The telescopic ends of the third hydraulic telescopic rods 34 are fixedly connected to the bottom of the corresponding movable plates 33. Elastic supports adapted to the diversion plate 2 are provided on the movable plates 33. Several support frames 38 are fixedly connected to the bottom of the screening box body 1. The bottom of the support frames 38... The unit is fixedly connected with an elastic pad 39. The guide includes a fixing strip 31 respectively set above and below the movable seat 28. The fixing strip 31 is fixedly connected to the inner wall of the screening box body 1. Two adjacent fixing strips 31 are fixedly connected by a guide plate 30, and the guide plate 30 passes through the movable seat 28. The elastic support includes a support strip 32 set above the movable plate 33. Several guide posts 35 are fixedly connected to the bottom of the support strip 32. The bottom end of the guide post 35 passes through the movable plate 33, and the bottom end of the guide post 35 is fixedly connected to a fixing plate 37 located below the movable plate 33. A second spring 36 is sleeved on the outside of the guide post 35. The two ends of the second spring 36 abut against the support strip 32 and the movable plate 33 respectively.

[0041] The movable plate 33 is driven to move upward by the third hydraulic telescopic rod 34. The movable plate 33 supports the bottom of the diversion plate 2 by the second spring 36 and the support bar 32. The movable seat 28 contacts a fixed bar 31 located above it. The movable seat 28 is in its highest position. The movable plate 33 is driven to move by the third hydraulic telescopic rod 34. By changing the height difference between the two support bars 32, the tilt angle of the diversion plate 2 can be adjusted. The diversion plate 2 and the second rotating shaft 29 rotate relative to the movable seat 28. Since the support bar 32 and the movable plate 33 are connected by the third hydraulic telescopic rod 34, the movable plate 33 moves upward by the third hydraulic telescopic rod 34. The two springs 36 are elastically connected. When the diversion plate 2 is subjected to the impact force generated by the downward movement of the material, the diversion plate 2, the second rotating shaft 29 and the movable seat 28 slide relative to the guide plate 30 and the screening box body 1. The diversion plate 2 drives the support bar 32 and the guide column 35 to slide relative to the movable plate 33. The second spring 36 can provide elastic buffering. The design of the support frame 38 supports the screening box body 1. The design of the elastic pad 39 prevents the support frame 38 from directly colliding with the ground when the internal components of the screening box body 1 vibrate.

[0042] This embodiment of a fluorite concentrate screening method uses the fluorite concentrate screening equipment described above and includes the following steps:

[0043] Step 1: Add the material to be screened into the screening box body 1 through the feed hopper 8. The material enters between the two side plates 5. The vibration mechanism drives the side plates 5 and the screening screen 6 to vibrate relative to the screening box body 1.

[0044] Step 2: Materials that meet the requirements are screened through the screening screen 6. The screened materials fall onto the diversion plate 2 and are discharged sequentially through the diversion plate 2 and the second discharge hopper 4.

[0045] Step 3: Materials that fail to pass through the screening screen 6 will eventually roll off the screening screen 6 and the support ring 15 onto the third discharge hopper 7, where they will be discharged.

[0046] Step 4: When it is necessary to clean the screen 6, the support ring 15 and the screen 6 are rotated 180 degrees by the flip cleaning structure so that the side of the screen 6 with material blockage is facing down. The flow divider plate 2 is rotated by the angle adjustment component so that the lower end of the flow divider plate 2 faces the first discharge hopper 3.

[0047] Step 5: The side plate 5 and the screen 6 are driven to vibrate relative to the screen box body 1 by the vibration mechanism. The material blocked on the screen 6 is shaken off onto the diversion plate 2. The cleaned material is discharged sequentially through the diversion plate 2 and the first discharge hopper 3.

[0048] Working Principle: During operation, the material to be screened is added to the screening box body 1 through the feed hopper 8. The material enters between the two side plates 5. The vibration mechanism drives the side plates 5 and the screening screen 6 to vibrate relative to the screening box body 1. The material rolls on several screening screens 6 and support rings 15. The material that meets the requirements is screened through the screening screens 6. The screened material falls onto the diversion plate 2, which transports the screened material to the second discharge hopper 4. The material that meets the requirements is discharged through the second discharge hopper 4. The material that does not pass through the screening screens 6 finally rolls from the screening screens 6 and support rings 15 to the third discharge hopper 7. The material that does not meet the requirements is discharged through the third discharge hopper 7. When it is necessary to clean the screening screens 6, the support rings 15 and the screening screens 6 are rotated 180 degrees by the flipping cleaning structure, so that the side of the screening screens 6 that is blocked with material faces down. The angle adjustment component drives the diversion plate 2 to rotate so that the lower end of the diversion plate 2 faces the first discharge hopper 3. The vibration mechanism drives the side plate 5 and the screen 6 to vibrate relative to the screening box body 1. The material blocked on the screen 6 is shaken off onto the diversion plate 2. The cleaned material rolls down the diversion plate 2 onto the first discharge hopper 3 and is discharged through the first discharge hopper 3. After the screen 6 is cleaned, the angle adjustment component drives the diversion plate 2 to rotate in the opposite direction to the initial position so that the lower end of the diversion plate 2 faces the second discharge hopper 4. The material to be screened can then be added back into the screening box body 1 through the feed hopper 8 to start the next round of material screening. This facilitates the screening of fluorite concentrate without the need for repeated disassembly and assembly of the screen 6. The cleaning of the screen 6 can be completed inside the screening box body 1, improving convenience.

[0049] The baffle plate 10 blocks the connection between two adjacent support rings 15 to prevent material from rolling into the gap between the two support rings 15. When it is necessary to drive the support rings 15 and the screen 6 to rotate 180 degrees, the first hydraulic telescopic rod 13 drives the first connecting plate 14 and the movable frame 9 to move relative to the side plate 5. The movable frame 9 drives the baffle plate 10 to move relative to the support rings 15 through the connecting column 11, so that the baffle plate 10 no longer contacts the support rings 15, avoiding interference with the rotation of the support rings 15 and the screen 6. Then, the second hydraulic telescopic rod 21 drives the second connecting plate 22 and the sliding seat 18 to move, and the sliding seat 18 moves relative to the guide. The guide sleeve 23 and the side plate 5 slide. The design of the guide sleeve 23 allows the sliding seat 18 to move smoothly relative to the side plate 5. The sliding seat 18 drives the gear 17 and the first rotating shaft 16 to rotate through the toothed plate 19. The first rotating shaft 16 can drive the support ring 15 and the screening screen 6 to flip. The design of the first fixed plate 25, the second fixed plate 26 and the first spring 27 allows the side plate 5 to be elastically connected relative to the screening box body 1. The vibration motor 24 is started. The vibration motor 24 drives the screening screen 6 and the first fixed plate 25 to vibrate relative to the second fixed plate 26 and the screening box body 1, so that the material can roll on several screening screens 6 and be screened through the screening screens 6.

[0050] The movable plate 33 is driven to move upward by the third hydraulic telescopic rod 34. The movable plate 33 supports the bottom of the diversion plate 2 by the second spring 36 and the support bar 32. The movable seat 28 contacts a fixed bar 31 located above it. The movable seat 28 is in its highest position. The movable plate 33 is driven to move by the third hydraulic telescopic rod 34. By changing the height difference between the two support bars 32, the tilt angle of the diversion plate 2 can be adjusted. The diversion plate 2 and the second rotating shaft 29 rotate relative to the movable seat 28. Since the support bar 32 and the movable plate 33 are connected by the third hydraulic telescopic rod 34, the movable plate 33 moves upward by the third hydraulic telescopic rod 34. The two springs 36 are elastically connected. When the diversion plate 2 is subjected to the impact force generated by the downward movement of the material, the diversion plate 2, the second rotating shaft 29 and the movable seat 28 slide relative to the guide plate 30 and the screening box body 1. The diversion plate 2 drives the support bar 32 and the guide column 35 to slide relative to the movable plate 33. The second spring 36 can provide elastic buffering. The design of the support frame 38 supports the screening box body 1. The design of the elastic pad 39 prevents the support frame 38 from directly colliding with the ground when the internal components of the screening box body 1 vibrate.
