Description

Technical Field

[0001] This utility model relates to the field of silica pressure filtration technology, specifically to a sedimentation pressure filtration device for silica processing. Background Technology

[0002] A sedimentation and filtration device for silica processing is a type of equipment used for solid-liquid separation during silica processing. It utilizes the principle of pressure filtration to separate liquid and solid particles through a filter cloth, forming a filter cake and a filtrate. This device is widely used in the wet production of silica and is one of the key pieces of equipment for achieving high-quality and high-efficiency production of silica products.

[0003] Existing patent CN220834331U discloses a sedimentation filter press device, including a filter press tank. Limiting frames are fixedly installed on both sides of the filter press tank. A lead screw is rotatably installed inside the limiting frame, and a slider is threaded on the outside of the lead screw. However, the feeding position of the above-mentioned sedimentation filter press device is fixed during use, which easily causes solid particles to accumulate on a certain area of ​​the filter cloth. This results in some areas of solid particles being over-compressed during filter pressing, while solid particles in other areas are not fully compressed, thus affecting the filter pressing effect and the quality of the filter cake. Therefore, a sedimentation filter press device for processing silica is proposed. Utility Model Content

[0022] like Figures 1 to 3 As shown, a sedimentation and filtration device for processing silica includes a filter box 1, which is a hollow rectangular box with open top and bottom. Four support legs 2 are fixedly installed at the bottom of the filter box 1, and a funnel 3 is fixedly installed at the bottom of the filter box 1. A filter plate 4 is fixedly installed inside the filter box 1, and a detachable square frame 6 is provided on the surface of the filter plate 4. A filter cloth 5 is fixedly installed inside the square frame 6. A frame 7 is provided on the top of the filter box 1, with open top and bottom. A feeding pipe 8 is provided inside the frame 7, and a flexible hose 9 is fixedly connected to the top end of the feeding pipe 8. A transmission assembly 10 for moving the feeding pipe 8 is provided on the frame 7. A strip plate 11 is fixedly installed on the side wall of the frame 7. A hydraulic rod 12 is fixedly installed at the bottom of the filter box 1, and a pressure plate 13 is fixedly connected to the output end of the hydraulic rod 12. A linear guideway for moving the frame 7 is provided on the side wall of the filter box 1. The reciprocating drive assembly 14 is used in the following process: During filter pressing, the silica slurry is first injected into the feed pipe 8 through the hose 9. At the same time, the transmission assembly 10 is activated, which drives the feed pipe 8 to move back and forth in a serpentine pattern inside the box frame 7. This allows the silica slurry to be evenly distributed on different positions on the surface of the filter cloth 5. At this time, the solid particles are evenly distributed on the surface of the filter cloth 5, while the liquid passes through the filter cloth 5 and the filter plate 4 and is discharged through the funnel 3. Then, the drive assembly 14 is controlled to move the box frame 7 away from the top of the filter box 1, so that the pressure plate 13 moves to the top of the filter box 1. Then, the hydraulic rod 12 is controlled to move the pressure plate 13 downward, using the pressure plate 13 to press the fixed particles on the filter cloth 5. Finally, the hydraulic rod 12 is controlled to move the pressure plate 13 upward, and the pressed filter cake can be removed.

[0023] like Figure 1 , Figure 3As shown, the transmission assembly 10 includes a strip-shaped hole 1001. A strip-shaped hole 1001 is formed on the side wall of the box frame 7. A lead screw 1002 is movably installed inside the strip-shaped hole 1001. A servo motor 1003 for driving the lead screw 1002 is fixedly installed on the side wall of the box frame 7. A moving block 1004 is threaded onto the lead screw 1002. A U-shaped frame 1005 is fixedly installed on the side wall of the moving block 1004. Slide grooves 1006 are formed on the two side walls inside the U-shaped frame 1005. A rectangular frame 1007 is provided inside the U-shaped frame 1005. The rectangular frame 1007 is movably installed inside the two slide grooves 1006. An injection pipe 8 is fixedly installed inside the rectangular frame 1007. An L-shaped plate 1008 is fixedly installed on the side wall of the rectangular frame 1007. A servo motor 1009 is fixedly installed inside the L-shaped plate 1008. The output end of the second machine 1009 is fixedly connected to a gear 1010. A rack 1011 is fixedly installed on the inner side wall of the U-shaped frame 1005. The rack 1011 and the gear 1010 are meshed together. It should be noted that after the first servo motor 1003 is started, it can drive the lead screw 1002 to rotate back and forth. The reciprocating rotation of the lead screw 1002 can cause the moving block 1004 to move linearly back and forth. While the moving block 1004 moves, it drives the U-shaped frame 1005 to move synchronously. After the second servo motor 1009 is started, it can drive the gear 1010 to rotate back and forth. The reciprocating rotation of the gear 1010 can drive the second servo motor 1009, the L-shaped plate 1008, and the rectangular frame 1007 to move linearly back and forth. While the rectangular frame 1007 moves, it slides inside the corresponding two slide grooves 1006, so that the injection pipe 8 can move back and forth in a serpentine path inside the box frame 7.

[0024] like Figure 1 , Figure 3 As shown, the transmission assembly 10 also includes an elongated hole 1012. The side wall of the box frame 7 has an elongated hole 1012. A stabilizing block 1013 is movably installed inside the elongated hole 1012. The stabilizing block 1013 and the U-shaped frame 1005 are fixedly connected. It should be noted that when the U-shaped frame 1005 moves linearly back and forth, it will drive the stabilizing block 1013 to slide back and forth inside the elongated hole 1012. The stabilizing block 1013 and the elongated hole 1012 limit the movement trajectory of the U-shaped frame 1005 on the one hand, and ensure the movement stability of the U-shaped frame 1005 on the other hand.

[0025] like Figure 1 , Figure 2As shown, the drive assembly 14 includes a strip frame 1401. The strip frame 1401 is fixedly installed on the side wall of the filter box 1. A threaded rod 1402 is movably installed inside the strip frame 1401. A servo motor 1403 for driving the threaded rod 1402 to rotate is fixedly installed on the side wall of the strip frame 1401. A movable block 1404 is threadedly connected to the threaded rod 1402. A bending frame 1405 is fixedly installed on the top of the movable block 1404. The bending frame 1405 is fixedly connected to the box frame 7. It should be noted that after the servo motor 1403 is started, it can drive the threaded rod 1402 to rotate back and forth. The back and forth rotation of the threaded rod 1402 can cause the movable block 1404 to move linearly back and forth. The movement of the movable block 1404 simultaneously drives the bending frame 1405, the filter box 1, the strip plate 11, the hydraulic rod 12, and the pressure plate 13 to move synchronously.

[0026] like Figure 1 , Figure 2 As shown, two U-shaped frames 15 are fixedly installed on the top of the frame 6. The inner side walls of the filter box 1 are respectively provided with slots 16. Each slot 16 has a movable block 17 installed inside. Each block 17 is fixedly connected to the frame 6. It should be noted that by holding the U-shaped frame 15 and pulling it upward, the frame 6 can be removed from the inside of the filter box 1, and the two blocks 17 can be disengaged from the corresponding slots 16.

[0027] like Figure 1 , Figure 2 As shown, a connecting rod 18 is fixedly installed at the bottom of the strip plate 11, and a limiting frame 19 is fixedly installed at the bottom of the connecting rod 18. It should be noted that when the pressure plate 13 is placed directly above the filter box 1, the limiting frame 19 will also be placed at the top of the filter box 1. The limiting frame 19 can restrict the card block 17 from moving upward from inside the card slot 16.

[0028] In summary:

[0029] During filter pressing, the silica slurry is first injected into the feed pipe 8 through the hose 9. At the same time, the transmission assembly 10 is activated, which drives the feed pipe 8 to move back and forth in a serpentine pattern inside the box frame 7, so that the silica slurry can be evenly fed onto different positions on the surface of the filter cloth 5. At this time, the solid particles are evenly distributed on the surface of the filter cloth 5, while the liquid passes through the filter cloth 5 and the filter plate 4 and is discharged through the funnel 3. Then, the drive assembly 14 is controlled, which moves the box frame 7 away from the top of the filter box 1, so that the pressure plate 13 moves to the top of the filter box 1. Then, the hydraulic rod 12 is controlled, which moves the pressure plate 13 downward, using the pressure plate 13 to press the fixed particles on the filter cloth 5. Then, the hydraulic rod 12 is controlled to move the pressure plate 13 upward, so that the pressed filter cake can be taken out.
