Description

Technical Field

[0001] The invention belongs to the technical field of disk filters, and specifically relates to a sediment prevention device for a disk filter. Background Art

[0002] A disk filter is an efficient solid-liquid separation device widely used in fields such as chemical industry, pharmaceuticals, food, and environmental protection. It forms a filtering unit through multiple parallelly arranged filter disks (usually fan-shaped or circular). The suspension passes through the filter cloth under the action of a pressure difference (vacuum or pressure). Solid particles are retained on the surface of the filter cloth to form a filter cake, and the clarified liquid passes through the filter cloth and is discharged. In order to ensure the filtering effect of the disk filter, a sediment prevention device is required to prevent solid impurities in the water from precipitating at the bottom of the tank.

[0003] A Chinese patent with the publication number CN202237497U discloses a sediment prevention device for a disk filter. This utility model uses a water spray pipe instead of a stirring shaft and stirring rake teeth. The stirring effect of blowing the water is better than mechanical stirring, which can effectively improve the utilization rate of the filter, stabilize the quality of the product, reduce the floor area, save electric energy, reduce production costs, avoid ore leakage, and improve the working environment.

[0004] The above patent uses a water spray pipe instead of a stirring shaft, and drives solid impurities to move through the water column ejected by the water spray pipe to prevent the fixed impurities from precipitating. However, since the water spray pipe extends into the tank, it means that the water spray pipe itself is in the water. When the water column is ejected, it will be affected by the resistance of the water in the tank, resulting in a short ejection distance of the water column. At the same time, when the water column is ejected, the flow velocity is too high near the water spray pipe and insufficient far from the water spray pipe. Therefore, the sediment prevention effect is poor.

[0005] Therefore, the present invention provides a sediment prevention device for a disk filter. Summary of the Invention

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] As Figures 1 to 6As shown in the figure, a sediment prevention device for a disk filter according to an embodiment of the present invention includes a tank body 1. A sealing plate 2 is fixedly installed on the inner wall of the tank body 1. A plurality of air outlet check valves 3 are fixedly installed on the inner wall of the sealing plate 2. A plurality of air inlet check valves 4 are fixedly installed on the inner wall of the back surface of the tank body 1. A push-pull plate 5 and a piston 6 are slidably installed on the inner wall of the tank body 1. The top of the push-pull plate 5 is fixedly connected to the bottom of the piston 6. A lifting assembly is arranged at the bottom of the push-pull plate 5. The inner wall of the tank body 1 is arc-shaped. The sealing plate 2 is fixed inside the tank body 1 to form a sealed cavity inside the tank body 1. When the disk filter is performing a filtering operation, the lifting assembly will drive the push-pull plate 5 to reciprocally lift. When the push-pull plate 5 lifts and lowers, it will drive the piston 6 to lift and lower in the sealed cavity. When the piston 6 descends, the pressure inside the sealed cavity decreases, and external air will enter the inside of the sealed cavity through the air inlet check valve 4. When the piston 6 ascends, the air inside the sealed cavity will be squeezed and discharged through the air outlet check valve 3. Both the air outlet check valve 3 and the air inlet check valve 4 are check valves. Therefore, gas and liquid can only move in one direction and will not flow back to ensure the normal operation of the device. Since the air outlet check valve 3 is located at a position close to the bottom of the tank body 1 and the inner wall of the tank body 1 is arc-shaped, impurities will approach the middle, that is, the position of the air outlet check valve 3 after descending. When the gas is discharged through the air outlet check valve 3, bubbles will be formed. Under the action of buoyancy, the bubbles will rise. When the bubbles rise, they will drive the water to move, generating a water flow and breaking the static state of the water. This kind of disturbance can prevent particle sedimentation. The water flow movement keeps the particles in a suspended state. At the same time, when the bubbles rise, they will directly rise to the top of the water and will not dissipate as the distance increases, thereby effectively preventing sedimentation. In addition, when the bubbles rise, they will adhere to the surface of the particles, reducing their overall density. Through the buoyancy of the bubbles, the solid particles in the water will float, making the sediment prevention effect better.

[0024] As Figures 1 to 7 shown, the lifting assembly includes a lifting block 7. The lifting block 7 is fixedly installed at the bottom of the push-pull plate 5. The lifting block 7 penetrates through the bottom of the tank body 1. A drive shaft 8 is arranged below the tank body 1. One end of the drive shaft 8 is fixedly installed with a rotating wheel 9. A rotating shaft 10 is fixedly installed on the outer wall of the rotating wheel 9. A transmission member 11 is rotatably installed on the outer wall of the rotating shaft 10. A transmission shaft 12 is rotatably installed between the transmission member 11 and the inner wall of the lifting block 7. A drive assembly is arranged outside the tank body 1. When the lifting assembly is working, the drive assembly will drive the rotating wheel 9 to rotate through the drive shaft 8. When the rotating wheel 9 rotates, it will drive the rotating shaft 10 to rotate. When the rotating shaft 10 rotates, it will drive the transmission shaft 12 to lift and lower through the transmission member 11. When the transmission shaft 12 lifts and lowers, it will drive the push-pull plate 5 to lift and lower through the lifting block 7, so as to realize the gas delivery work by lifting and lowering the piston 6 in the sealed cavity.

[0025] As Figures 1 to 7As shown in the figure, the driving component includes a driving motor 13. The driving motor 13 is located on the back of the trough body 1. A driving wheel 14 is fixedly installed on the outer wall of the output shaft of the driving motor 13. One end of the driving shaft 8 away from the rotating wheel 9 is fixedly installed with a driven wheel 15. A transmission belt 16 is installed between the outer walls of the driven wheel 15 and the driving wheel 14 in a transmission manner. After the driving motor 13 is started, it will drive the driving wheel 14 to rotate. When the driving wheel 14 rotates, it will drive the driven wheel 15 to rotate through the transmission belt 16. When the driven wheel 15 rotates, it will drive the driving shaft 8 to rotate, thereby providing power for the rotation of the driving shaft 8.

[0026] As Figures 1 to 3 and Figures 7 to 8 shown in the figure, scraping plates 17 are symmetrically and slidably installed on the inner wall of the trough body 1. A counterweight block 18 is fixedly installed on the inner wall of the scraping plate 17. A pulling component is arranged at the bottom of the trough body 1. When the rotating wheel 9 rotates, it will drive the scraping plates 17 to reciprocally slide along the inner wall of the trough body 1 through the pulling component. The scraping plates 17 increase their weight through the counterweight blocks 18 and keep in contact with the inner wall of the trough body 1. When the scraping plates 17 slide on the inner wall of the trough body 1, they can clean the inner wall of the trough body 1 to prevent impurities from adhering to the inner wall of the trough body 1. When the scraping plates 17 move, they can disturb the water flow near the inner wall in the trough body 1, thereby achieving the effect of preventing sedimentation. In addition, when the scraping plates 17 slide downward, they can push the impurity particles near the inner wall of the trough body 1 towards the middle position of the trough body 1. When the impurity particles move towards the middle, they will float under the action of the rising bubbles, thereby improving the anti-sedimentation effect.

[0027] As Figures 1 to 3 and Figures 7 to 8 shown in the figure, the pulling component includes two connecting belts 19. One end of each of the two connecting belts 19 is wound around the outer wall of the rotating wheel 9. The ends of the two connecting belts 19 away from the rotating wheel 9 are respectively fixedly connected to the outer walls of the two scraping plates 17. Two groups of guide wheels 20 are fixedly installed on the outer wall of the trough body 1. The two groups of guide wheels 20 are respectively in transmission connection with the two connecting belts 19. Three partition plates 21 are fixedly installed on the outer wall of the rotating wheel 9. When the driving motor 13 rotates, it will rotate reciprocally. When the driving motor 13 rotates forward, the rotating wheel 9 will rotate forward accordingly. When the rotating wheel 9 rotates forward, it will loosen the connecting belt 19 wound around it above, and the scraping plate 17 at the other end of the connecting belt 19 will slide down along the inner wall of the trough body 1 under the action of gravity, thereby performing the cleaning work. When the driving motor 13 rotates in reverse, the rotating wheel 9 will rotate in reverse accordingly. By reversing the rotating wheel 9, the connecting belt 19 is wound up, thereby pulling the scraping plate 17 to move upward. Through the reciprocating rotation of the driving motor 13, the scraping plates 17 reciprocally move up and down, realizing continuous cleaning of the trough body 1. The outer side of the rotating wheel 9 is divided into two areas by the partition plates 21, and the two areas are respectively used to store the two connecting belts 19 to prevent the connecting belts 19 from getting disordered.

[0028] As Figure 2 and Figure 5As shown in the figure, a stirring shaft 22 is rotatably installed on the inner wall of the tank body 1. The output shaft of the driving motor 13 is fixedly connected to one end of the stirring shaft 22. A plurality of stirring plates 23 are fixedly installed on the outer wall of the stirring shaft 22. When the driving motor 13 rotates, it will drive the stirring shaft 22 to rotate reciprocally. When the stirring shaft 22 rotates reciprocally, it will drive the stirring plates 23 to rotate. Through the rotation of the stirring plates 23, the water body can be driven to flow. At the same time, the stirring plates 23 are located above the air outlet check valve 3. When the air outlet check valve 3 forms bubbles, the bubbles will rise and pass through the stirring plates 23. During the rising process, the bubbles will drive the surrounding liquid to move together. This helps to resuspend the solid particles that are about to precipitate in the liquid. The rotation of the stirring plates 23 will increase the movement form of the water, further strengthening this suspension effect and making it more difficult for the particulate matter to form sediment. In addition, when the stirring plates 23 rotate, they will agitate the rising bubbles. The rising bubbles will form more small bubbles under the action of the stirring plates 23. After the large bubbles become small bubbles, the surface area will increase, and the collision probability with the particles will be improved, thereby significantly improving the anti-sedimentation effect of the device.

[0029] As Figures 5 to 6 and Figure 9 shown in the figure, positioning seats 24 are symmetrically and fixedly installed on the top of the sealing plate 2. A torsion spring shaft 25 is fixedly installed on the inner wall of the positioning seat 24. A guide plate 26 is fixedly installed on the outer wall of the torsion spring shaft 25. Since the guide plate 26 is inclined and located above the outermost air outlet check valve 3, when the outermost air outlet check valve 3 generates bubbles, the bubbles will rise under the action of buoyancy until they contact the upper guide plate 26. When the bubbles contact the guide plate 26, due to the blockage of the guide plate 26, they cannot move directly upward, but move obliquely upward along the inclined surface of the guide plate 26. When the bubbles cross the highest point of the guide plate 26, they will no longer be directly blocked by the guide plate 26. At this time, buoyancy will once again dominate the movement of the bubbles, making them continue to move upward. Through the action of the inclined surface of the guide plate 26, the bubbles will expand to both sides. In addition, when the stirring plates 23 rotate, the stirring plates 23 will squeeze the guide plate 26, and the guide plate 26 will flip to both sides around the torsion spring shaft 25. While the guide plate 26 flips, the bubbles rising along the guide plate 26 can rise evenly within the flipping range of the guide plate 26, enabling the bubbles to evenly cover a larger area and improving the anti-sedimentation effect of the device.

[0030] As Figures 5 to 6 and Figure 9As shown, arc-shaped bumps 27 are fixedly installed on the outer walls of the two guide plates 26 close to each other, and porous sieve plates 28 are fixedly installed on the outer walls of the two guide plates 26 away from each other; when the stirring plate 23 presses against the guide plate 26, it will press against the arc-shaped bump 27 along the surface of the guide plate 26. The arc-shaped bump 27 can increase the turning angle of the guide plate 26, thereby increasing the coverage area of the bubbles. When the bubbles rise along the inclined surface of the guide plate 26, they will pass through the porous sieve plate 28. After passing through the porous sieve plate 28, the bubbles can form more small bubbles, thereby increasing the anti-settling effect by increasing the surface area of the bubbles.

[0031] As Figures 5 to 6 and Figure 9 shown, inner baffles 29 are fixedly installed on the outer walls of the two positioning seats 24 close to each other. The outer walls of the two inner baffles 29 are respectively in contact with the outer walls of the two guide plates 26. Outer baffles 30 are fixedly installed on the outer walls of the two positioning seats 24 away from each other; the inner baffle 29 blocks the guide plate 26 to prevent the guide plate 26 from rotating in the reverse direction and jamming with the stirring plate 23. The outer baffle 30 blocks the guide plate 26 to prevent the guide plate 26 from over-turning due to inertia and colliding with the air outlet one-way valve 3.

[0032] As Figure 1 and Figure 3 shown, a mounting frame 31 is fixedly installed on the back of the tank body 1. The driving motor 13 is fixedly installed inside the mounting frame 31. A shaft seat 32 is fixedly installed at the bottom of the tank body 1. The driving shaft 8 is rotatably installed on the inner wall of the shaft seat 32. A base 33 is fixedly installed at the bottom of the tank body 1; the mounting frame 31 fixes the driving motor 13 and provides a fulcrum for the driving motor 13, so that the driving motor 13 can stably provide power for the operation of the device. The shaft seat 32 limits the driving shaft 8 to ensure the stability of power transmission. The base 33 is used to support the entire device, ensuring the stability of the device and making the device at a suitable working height.

[0033] Working principle: The sealing plate 2 is fixed inside the trough body 1 to form a sealed cavity inside the trough body 1. When the disk filter is performing the filtering operation, the lifting assembly will drive the push-pull plate 5 to reciprocate up and down. When the push-pull plate 5 moves up and down, it will drive the piston 6 to move up and down in the sealed cavity. When the piston 6 descends, the pressure inside the sealed cavity decreases, and external air will enter the sealed cavity through the intake check valve 4. When the piston 6 ascends, the air inside the sealed cavity is squeezed and will be discharged through the outlet check valve 3. Both the outlet check valve 3 and the intake check valve 4 are check valves. Therefore, gas and liquid can only move in one direction and will not flow back to ensure the normal operation of the device. Since the outlet check valve 3 is located near the bottom of the trough body 1 and the inner wall of the trough body 1 is arc-shaped, impurities will approach the middle, that is, the position of the outlet check valve 3 after descending. When the gas is discharged through the outlet check valve 3, bubbles will be formed. Under the action of buoyancy, the bubbles will rise. When the bubbles rise, they will drive the water to move and generate water flow, breaking the static state of the water. This disturbance can prevent particle sedimentation. The water flow movement keeps the particles in a suspended state. At the same time, when the bubbles rise, they will directly rise to the top of the water and will not dissipate as the distance increases, thus effectively preventing precipitation. In addition, when the bubbles rise, they will adhere to the surface of the particles, reducing their overall density. The buoyancy of the bubbles makes the solid particles in the water float, making the anti-sedimentation effect better. When the lifting assembly is working, the driving assembly will drive the rotating wheel 9 to rotate through the driving shaft 8. When the rotating wheel 9 rotates, it will drive the rotating shaft 10 to rotate. When the rotating shaft 10 rotates, it will drive the transmission shaft 12 to move up and down through the transmission member 11. When the transmission shaft 12 moves up and down, it will drive the push-pull plate 5 to move up and down through the lifting block 7, so that the piston 6 moves up and down in the sealed cavity to realize the gas delivery work. After the driving motor 13 is started, it will drive the driving wheel 14 to rotate. When the driving wheel 14 rotates, it will drive the driven wheel 15 to rotate through the transmission belt 16. When the driven wheel 15 rotates, it will drive the driving shaft 8 to rotate, thus providing power for the rotation of the driving shaft 8.

[0034] When the rotating wheel 9 rotates, it will drive the scraper 17 to reciprocate and slide along the inner wall of the trough 1 through the pulling component. The scraper 17 increases its weight through the counterweight 18 and keeps in contact with the inner wall of the trough 1. When the scraper 17 slides on the inner wall of the trough 1, it can clean the inner wall of the trough 1 to prevent impurities from adhering to the inner wall of the trough 1. When the scraper 17 moves, it can disturb the water flow near the inner wall in the trough 1, thus achieving the effect of preventing sedimentation. In addition, when the scraper 17 slides downward, it can push the impurity particles near the inner wall of the trough 1 towards the middle position of the trough 1. When the impurity particles move towards the middle, they will float under the action of the rising bubbles, thereby improving the anti-sedimentation effect. When the driving motor 13 rotates, it will rotate reciprocally. When the driving motor 13 rotates forward, the rotating wheel 9 will rotate forward accordingly. When the rotating wheel 9 rotates forward, it will loosen the connecting belt 19 wound above it, and the scraper 17 located at the other end of the connecting belt 19 will slide down along the inner wall of the trough 1 under the action of gravity, thus performing the cleaning work. When the driving motor 13 rotates in reverse, the rotating wheel 9 will rotate in reverse accordingly. By reversing the rotating wheel 9, the connecting belt 19 is wound up, thereby pulling the scraper 17 upward. Through the reciprocating rotation of the driving motor 13, the scraper 17 reciprocates up and down, realizing the continuous cleaning of the trough 1. When the driving motor 13 rotates, it will drive the stirring shaft 22 to rotate. When the stirring shaft 22 rotates, it will drive the stirring plate 23 to rotate. Through the rotation of the stirring plate 23, the water body can be driven to flow, and the water flow drives the particles to move and keeps them suspended, thus preventing the particles from settling. In addition, when the stirring plate 23 rotates, it will stir the rising bubbles. The rising bubbles will form more small bubbles under the action of the stirring plate 23. After the large bubbles turn into small bubbles, the surface area will increase, and the collision probability with the particles will be improved, thereby significantly improving the anti-sedimentation effect of the device.

[0035] Since the guide plate 26 is inclined and located above the outermost air outlet check valve 3, when the outermost air outlet check valve 3 generates bubbles, the generated bubbles will move along the inclined surface of the guide plate 26 towards both sides, enabling the bubbles to expand towards both sides. In addition, when the stirring plate 23 rotates, the stirring plate 23 will squeeze the guide plate 26, and the guide plate 26 will flip towards both sides around the torsion spring shaft 25. While the guide plate 26 flips, the bubbles rise along the guide plate 26 and can rise evenly within the flipping range of the guide plate 26, enabling the bubbles to evenly cover a larger area and improving the anti-sedimentation effect of the device. When the stirring plate 23 squeezes the guide plate 26, it will squeeze the arc-shaped convex block 27 along the surface of the guide plate 26. Through the arc-shaped convex block 27, the flipping angle of the guide plate 26 can be increased, thereby increasing the coverage area of the bubbles. When the bubbles rise along the inclined surface of the guide plate 26, they will pass through the porous sieve plate 28. After passing through the porous sieve plate 28, the bubbles can form more small bubbles, thereby increasing the anti-sedimentation effect by increasing the surface area of the bubbles.
