Description

Technical Field

[0001] This utility model relates to the field of vacuum filter technology, and in particular to a ceramic vacuum filter with zoned filtration. Background Technology

[0002] A vacuum filter is a general-purpose device that uses vacuum negative pressure to achieve solid-liquid separation. The core principle is to create negative pressure on one side of the filter medium by a vacuum pump, so that the liquid in the slurry to be filtered passes through the filter medium under the action of pressure difference, and the solid particles are trapped to form a filter cake, thereby completing the separation. It is widely used in mining, chemical, environmental protection and food industries. Common types include rotary drum, disc and belt. Among them, the rotary drum is the most widely used in industry because it can operate continuously and has a large processing capacity. The equipment usually includes core components such as slurry tank, filter element, vacuum system and unloading mechanism.

[0003] Existing equipment mostly uses a single rigid scraper to remove filter cake. The scraper is in rigid contact with the ceramic plate surface, which can easily scratch the micropores of the ceramic membrane due to uneven contact pressure. Moreover, for filter cakes with strong viscosity or containing fibers, incomplete scraping often occurs. The preload of the spring can be used to push the scraper to always stick to the ceramic surface. In addition, a high-pressure nozzle at a certain angle to the ceramic can be used to ensure that the filter cake on the ceramic surface is cleaned. At the same time, the internal negative pressure control stability of existing ceramic vacuum filters with zoned filtration is insufficient. The solid-liquid ratio and flow rate of the material in different areas of the suction zone and the filtration zone are different, which will cause fluctuations in the load of the vacuum system and thus adsorption failure. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a ceramic vacuum filter with zoned filtration, aiming to improve the problem in the prior art where uneven contact pressure can easily scratch the micropores of the ceramic membrane.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a ceramic vacuum filter with zoned filtration, comprising a water tank, protruding grooves fixedly connected to the front and rear sides of the water tank, a rotating column rotatably connected to the top of the water tank, a support plate fixedly connected to the outer wall of the rotating column, ceramic blocks fixedly connected to the outer wall of the support plate, fixed rods fixedly connected to the front and rear sides of the top of the water tank, scraper blades slidably connected to the left and right sides of the inner walls of the multiple fixed rods, scraper blades slidably connected to the opposite sides of the inner walls of the multiple fixed rods, columnar protrusions fixedly connected to the opposite sides of the multiple fixed rods, springs provided on the inner walls of the multiple fixed rods, and compensation mechanisms provided on the inner walls of the multiple ceramic blocks, the compensation mechanisms being used to compensate for the instability of the negative pressure inside the ceramic blocks.

[0006] As a further description of the above technical solution:

[0007] The compensation mechanism includes multiple fixed blocks. Each adjacent side of the multiple fixed blocks is fixedly connected to the inner wall of the ceramic block. Each opposite side of the multiple fixed blocks is fixedly connected to a support ring. Each inner wall of the multiple support rings is slidably connected to a sliding cover I. Each inner wall of the multiple sliding cover I is fixedly connected to a piston. Each inner wall of the multiple support rings is slidably connected to a sliding cover II. Each inner wall of the multiple sliding cover II is fixedly connected to a hollow block. The inner wall of the hollow block is provided with a disc spring.

[0008] As a further description of the above technical solution:

[0009] Each of the protruding slots has a support block fixedly connected to its top, and the top of each of the support blocks has two main water pipes fixedly connected to its top.

[0010] As a further description of the above technical solution:

[0011] Each of the two main water pipes is connected to a branch water pipe on one adjacent side, and each of the multiple branch water pipes is connected to a high-pressure nozzle on one adjacent side.

[0012] As a further description of the above technical solution:

[0013] A protective shell is fixedly connected to the right side of the water tank, and a motor is fixedly connected to the right side of the protective shell.

[0014] As a further description of the above technical solution:

[0015] The output end of the motor is fixedly connected to a rotating rod, and the left end of the rotating rod is fixedly connected to a gear.

[0016] As a further description of the above technical solution:

[0017] The right end of the rotating column is fixedly connected to a gear two, and each of the multiple ceramic blocks is connected to a connecting pipe on an adjacent side.

[0018] As a further description of the above technical solution:

[0019] Both sliding cover one and sliding cover two have spherical protrusions fixedly connected to their opposite sides, and the outer wall of the piston is slidably connected to the inner wall of the hollow block.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the ceramic block is driven to rotate by a motor, and the filter cake on the surface of the ceramic block is scraped off by scraper blade one and scraper blade two. The high-pressure nozzle sprays clean water at a small angle to the ceramic surface to perform high-pressure rinsing on the ceramic surface, so that the residue attached to the surface of the ceramic micropores falls off. When the ceramic surface becomes uneven, it will push scraper blade one and scraper blade two to slide inward into the fixed rod, and the cylindrical protrusion will squeeze the internal spring.

[0022] 2. In this utility model, under normal circumstances, the negative pressure causes the sliding cover one and the sliding cover two to slide along the inner wall of the support ring and move away from each other. The piston and the hollow block compress the disc spring. When the negative pressure decreases, the disc spring pushes the piston and the hollow block, causing the piston and the hollow block to drive the sliding cover one and the sliding cover two to move closer to each other, thereby increasing the internal space of the ceramic block and thus compensating for the instability of the negative pressure.

The ceramic block 6 is fixedly connected to the outer wall of the support plate 5. The surface of the ceramic block 6 has numerous micropores, which utilize capillary effect to achieve solid-liquid separation, allowing liquid to pass through and trapping solid particles to form a filter cake. Fixed rods 7 are fixedly connected to the front and rear sides of the top of the water tank 1, providing sliding tracks and mounting bases for scraper blade 8 and scraper blade 9.

Compensation mechanisms 2 are provided on the inner walls of multiple ceramic blocks 6.

[0033] Please see the appendix Figure 2 - Appendix Figure 4 The compensation mechanism 2 includes multiple fixing blocks 201. The fixing blocks 201 are important components that fix the entire compensation mechanism 2 inside the ceramic block 6. The adjacent sides of the multiple fixing blocks 201 are fixedly connected to the inner wall of the ceramic block 6. The opposite sides of the multiple fixing blocks 201 are fixedly connected to support rings 202.

The disc spring 207 is located between the piston 204 and the left inner wall of the hollow block 206.

[0034] Specifically, the compensation mechanism 2 includes multiple fixed blocks 201. The fixed blocks 201 are crucial components that fix the entire compensation mechanism 2 inside the ceramic block 6, ensuring that the compensation mechanism 2 moves synchronously with the ceramic block 6. Adjacent sides of the multiple fixed blocks 201 are fixedly connected to the inner wall of the ceramic block 6. Support rings 202 are fixedly connected to the opposite sides of the multiple fixed blocks 201.

Sliding cover 1 203 is slidably connected to the left side of the inner wall of the multiple support rings 202. The sliding cover 1 203 can slide left and right along the inner wall of the support rings 202 to change the internal volume. A piston 204 is fixedly connected to the right side of each sliding cover 203. The piston 204 moves with the sliding cover 203 and slides within the hollow block 206. A sliding cover 205 is slidably connected to the right side of the inner wall of each of the multiple support rings 202. The sliding cover 205 can slide left and right along the inner wall of the support ring 202 to adjust the space in conjunction with the sliding cover 203. A hollow block 206 is fixedly connected to the left side of each of the multiple sliding covers 205. The hollow block 206 provides a sliding channel for the piston 204 and accommodates the disc spring 207. The inner wall of the hollow block 206 is provided with the disc spring 207, which is located between the piston 204 and the left inner wall of the hollow block 206. The disc spring 207 pushes the piston 204 and the sliding cover 203 through its own elastic deformation to counteract the effects of negative pressure fluctuations.

[0035] Please see the appendix Figure 3 - Appendix Figure 5 Support blocks 12 are fixedly connected to the top of multiple protruding slots 3. Two main water pipes 13 are fixedly connected to the top of multiple support blocks 12. The left end of the main water pipes 13 is connected to the water source and water pump. The other side of the top of the two main water pipes 13 is connected to the branch water pipes 14. The branch water pipes 14 are responsible for guiding water to multiple high-pressure nozzles 15. The adjacent side of the multiple branch water pipes 14 is connected to the high-pressure nozzles 15. A protective shell 16 is fixedly connected to the right side of the water tank 1. A motor 17 is fixedly connected to the right side of the protective shell 16. The motor 17 is used for the rotation drive of the entire ceramic vacuum filter.

[0036] Specifically, a support block 12 is fixedly connected to the top of each of the multiple protruding grooves 3. The support block 12 is used to fix and support the main water pipe 13 to keep it stable. Two main water pipes 13 are fixedly connected to the top of the multiple support blocks 12. The left end of the main water pipe 13 is connected to the water source and water pump to deliver high-pressure water to the distribution pipe 14. The other side of the top of the two main water pipes 13 is connected to the distribution pipe 14. The distribution pipe 14 is responsible for guiding the water to multiple high-pressure nozzles 15 to realize the diversion and precise delivery of water. The adjacent side of the multiple distribution pipes 14 is connected to the high-pressure nozzle 15. The high-pressure nozzle 15 sprays high-pressure water onto the surface of the ceramic block 6 to wash away residual filter cake impurities. A protective shell 16 is fixedly connected to the right side of the water tank 1. The protective shell 16 is used to protect the internal gear 19 and gear 20 from external pollution and collision. A motor 17 is fixedly connected to the right side of the protective shell 16. The motor 17 is used to drive the rotation of the entire ceramic vacuum filter and provides power for the rotation of the rotating column 4.

[0037] Please see the appendix Figure 1 - Appendix Figure 3 The output end of the motor 17 is fixedly connected to a rotating rod 18. The left end of the rotating rod 18 is fixedly connected to a gear 19. The right end of the rotating column 4 is fixedly connected to a gear 20. Gear 20 and gear 19 are meshed together. A connecting pipe 21 is connected to each adjacent side of the multiple ceramic blocks 6. The connecting pipe 21 is used to connect the interior of the ceramic block 6 to the evacuation device and the water-air separation device. Spherical protrusions 22 are fixedly connected to the opposite sides of the sliding cover 1 203 and the sliding cover 2 205. The spherical protrusions 22 prevent the sliding cover 1 203 and the sliding cover 2 205 from directly sticking to the inner wall of the ceramic block 6 and causing blockage of the micropores on the ceramic surface. The outer wall of the piston 204 is slidably connected to the inner wall of the hollow block 206.

[0038] Specifically, a rotating rod 18 is fixedly connected to the output end of motor 17. The rotating rod 18 transmits the power of motor 17 to gear 19. Gear 19 is fixedly connected to the left end of rotating rod 18. Gear 19 drives gear 20 to rotate through meshing, realizing the transmission of power and adjustment of speed. Gear 20 is fixedly connected to the right end of rotating column 4. Gear 20 meshes with gear 19 and transmits power to rotating column 4 to make it rotate. Connecting pipes 21 are connected to adjacent sides of multiple ceramic blocks 6. Connecting pipes 21 are used to connect ceramic blocks 6 to connecting ceramic blocks 6. The interior of ceramic block 6 is connected to the vacuum device and the water-air separation device to establish a negative pressure environment and export the filtrate. Spherical protrusions 22 are fixedly connected to the opposite sides of sliding cover 1 203 and sliding cover 205. The spherical protrusions 22 prevent sliding cover 1 203 and sliding cover 205 from directly sticking to the inner wall of ceramic block 6 and blocking the micropores on the ceramic surface, thus ensuring the normal filtration function of the micropores. The outer wall of piston 204 is slidably connected to the inner wall of hollow block 206 to ensure that piston 204 moves smoothly in hollow block 206 to achieve negative pressure compensation.

[0039] Working principle: The motor 17 drives the gear 19 to rotate through the rotating rod 18. The gear 19 drives the gear 20 to rotate, which in turn drives the rotating column 4 to rotate. The rotating column 4 drives the ceramic block 6 to rotate through the support plate 5. The filter cake on the surface of the ceramic block 6 is scraped off by the scraper blades 8 and 9. The high-pressure nozzle 15 sprays clean water at a small angle to the ceramic surface to perform high-pressure rinsing, causing the residue attached to the surface of the ceramic micropores to fall off. When the ceramic surface becomes uneven, it will push the scraper blades 8 and 9 to slide inward into the fixed rod 7, and the cylindrical protrusion 10 will compress the internal spring 11.

[0040] Under normal circumstances, the negative pressure causes the sliding cover 203 and the sliding cover 205 to slide along the inner wall of the support ring 202 and move away from each other. The piston 204 and the hollow block 206 exert pressure on the disc spring 207. When the negative pressure decreases, the disc spring 207 generates a thrust on the piston 204 and the hollow block 206, causing the piston 204 and the hollow block 206 to drive the sliding cover 203 and the sliding cover 205 to move closer to each other, thereby increasing the internal space of the ceramic block 6 and compensating for the instability of the negative pressure.
