Description

Technical Field

[0001] This invention relates to the field of filter press cleaning technology, specifically to a filter plate rinsing and cleaning structure for a filter press. Background Technology

[0002] A filter press is a machine that applies mechanical force to one side of the filter medium to achieve filtration. It is mainly used for solid-liquid separation of sludge (water) and is suitable for sludge dewatering in wastewater treatment processes in urban sewage treatment plants, pharmaceuticals, electroplating, papermaking, leather, printing and dyeing, metallurgy, chemical industry, slaughtering, food, brewing and environmental protection projects. It can also be used for solid-liquid separation in industrial production and is an ideal equipment for environmental management and resource recycling.

[0003] After filtration, the filter cake adheres tightly to the surface of the filter plates in a plate and frame filter press. While most of the filter cake can be removed by tapping and vibration, a small amount remains, affecting the overall filtration efficiency. Therefore, after a period of use, the filter plates require deep cleaning. Due to limited space on the plate and frame filter press frame and the small distance each filter plate can move, only one filter plate can be moved at a time between its two adjacent plates. Then, a brush and high-pressure nozzle are used to spray the filter cake from the upper part of the plate towards the filter plate. The filter plate is moved down to the lower side to clean both sides of the filter plate. At this point, the filter residue remaining on the surface of the filter plate is cleaned by the brushes and high-pressure nozzles. However, the filter plate cannot be moved from its position between the brushes and high-pressure nozzles on both sides. Therefore, the brushes and high-pressure nozzles on both sides need to be driven up to the upper side of the filter plate before the filter plate can be moved away and the next filter plate can be moved to the cleaning position. In this way, although the filter plates on both sides can be cleaned, the second cleaning is not very necessary. At the same time, it takes time to drive the brushes and high-pressure nozzles to reset, resulting in low efficiency of filter plate cleaning. Summary of the Invention

[0008] The second drive mechanism includes a second motor, which is fixedly connected to the sliding frame, and a first synchronous pulley is fixedly connected to the front end of the output shaft of the second motor. A first synchronous belt is provided on the surface of the first synchronous pulley, and second synchronous pulleys are symmetrically arranged on the upper and lower sides of the first synchronous pulley.

[0010] A fixing ring is fixedly connected to the surface of the first connecting rod. Second locking blocks are symmetrically rotatably connected to the front and rear sides of the fixing ring. Elastic ropes are fixedly connected to the surfaces of the second locking blocks, with the other end of the elastic ropes fixedly connected to the fixing ring. A rotating ring is rotatably connected to the inner side of the fixing ring. Multiple grooves are evenly distributed on the surface of the rotating ring in a circular array.

[0011] Multiple inclined blocks are uniformly fixedly connected to the surfaces of the upper and lower rotating rings on opposite sides. These inclined blocks are arranged in a circular array on the surface of the rotating rings, and the number of inclined blocks is twice the number of grooves. Semicircular frames are fixedly connected to the surfaces of the first sliding plates on both sides, one above the upper rotating ring and the other below the lower rotating ring.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] In this invention, when cleaning the filter plate, the filter plate to be cleaned is first moved to the inside of the sliding frame. Then, the first drive mechanism and the cleaning mechanism on both the upper and lower sides are activated. The first drive mechanism can drive the cleaning mechanism to move downward from the upper side of the filter plate or upward from the lower side of the filter plate through the docking mechanism. When the upper first drive mechanism drives the cleaning mechanism to the middle position of the filter plate through the docking mechanism on its surface, the cleaning mechanism will dock with the docking mechanism on the surface of the lower first drive mechanism. At this time, the docking mechanism on the upper side that docked with the cleaning mechanism will directly release the cleaning mechanism. At this time, the first drive mechanisms on both the upper and lower sides will begin to reset, and the lower first drive mechanism will drive the cleaning mechanism to move downward to the bottom position of the filter plate, while the upper first drive mechanism will move downward. The cleaning mechanism moves to the top position of the filter plate, and after moving from the top position to the bottom position, it completes one cleaning of the filter plate. At this time, the cleaned filter plate can be driven to move away, and at the same time, the first motor drives the threaded rod to rotate. When the threaded rod rotates, it drives the sliding frame to slide to the right, and then drives the next filter plate to move to the left to the cleaning position. When the next filter plate is in the cleaning position, the first motor stops, and then the first drive mechanism and the cleaning mechanism on the upper and lower sides are driven again to clean the filter plate. This device completes the cleaning of the filter plate by driving the cleaning mechanism to move from one side of the filter plate to the other side. At the same time, the first drive mechanism that drives the cleaning mechanism to move the cleaning does not obstruct the movement of the filter plate, so as to achieve the effect of quickly cleaning the next filter plate and effectively improve the cleaning efficiency of the filter plate.

[0015] When the water spray pipe moves to clean the filter plate, the second motor drives the first synchronous wheel to rotate. The first synchronous wheel, via the first synchronous belt, drives the second synchronous wheels on both sides to rotate. The rotation of the second synchronous wheels drives the telescopic rod to rotate, which in turn drives the first bevel gear to rotate. The first bevel gear, in turn, drives the reciprocating screw at the rear position to rotate via the second bevel gear. The rotation of the reciprocating screw at the rear position drives the third synchronous wheel connected to it to rotate. The rotation of the third synchronous wheel, via the second synchronous belt, drives the third synchronous wheel at the front to rotate. The third synchronous wheel at the front drives the reciprocating screw at the front position to rotate. The rotation of the reciprocating screws on both sides drives the second sliding plate to move up and down. When the third synchronous wheels on both sides rotate, the third synchronous wheels, via the connecting rods on their surfaces, drive the first sliding plate to slide back and forth continuously on the surface of the sliding frame. The back and forth movement of the first sliding plate drives the second sliding plate to move back and forth via the sliding rods. The second sliding plate drives the water spray pipe and the brush to move back and forth, thereby further improving the cleaning effect of the brush and the rinsing effect of the high-pressure nozzle.

[0031] Please see Figures 1-13 This invention provides a technical solution: a filter plate rinsing and cleaning structure for a filter press, comprising a frame 1, filter plates 2, and a base plate 3. Multiple filter plates 2 are provided, and all filter plates 2 are slidably disposed on the surface of the frame 1. The base plate 3 is located at the rear of the frame 1. A support frame 4 is fixedly connected to the upper surface of the base plate 3. A sliding frame 5 is slidably connected to the surface of the support frame 4. A first motor 6 is fixedly connected to the left side of the support frame 4. A threaded rod 7 is fixedly connected to the right end of the output shaft of the first motor 6. The threaded rod 7 is rotatably connected to the support frame 4 and threadedly engaged with the sliding frame 5. A cleaning mechanism is provided inside the sliding frame 5. The cleaning mechanism is used to clean the filter plate 2 located inside the sliding frame 5; the sliding frame 5 is symmetrically provided with a first drive mechanism on the upper and lower sides of the surface. The first drive mechanism is used to drive the cleaning mechanism to move vertically from one side of the filter plate 2 to the other side to complete the cleaning of the filter plate 2; the surface of the first drive mechanism is provided with a docking mechanism. The docking mechanism is used to dock the cleaning mechanism with the first drive mechanism. When the first drive mechanism drives the cleaning mechanism to dock with the docking mechanism on the other side, the cleaning mechanism is released from the first drive mechanism. When the first drive mechanism is reset, it can move the filter plate 2 on the surface of the frame 1 without affecting the movement of the filter plate 2.

[0032] During operation, after filtration, filter residue adheres to the surface of the filter plates in a plate and frame filter press, making it difficult to remove and affecting the overall filtration efficiency. Therefore, after a period of use, the filter plates require deep cleaning. Due to the limited space on the frame of the plate and frame filter press, each filter plate can only move one plate at a time between its two adjacent plates. Then, the brushes and high-pressure nozzles are driven from the upper side of the filter plate downwards to the lower side to clean both sides of the filter plate. At this point, the remaining filter residue on the surface of the filter plate is cleaned by the brushes and high-pressure nozzles. However, at this time, the brushes and high-pressure nozzles on both sides of the filter plate... Since the filter plate cannot be moved from its current position, the brushes and high-pressure nozzles on both sides need to be moved upwards to the upper part of the filter plate before the filter plate can be moved away and the next filter plate can be moved to the cleaning position. Although this can clean the filter plates on both sides, the second cleaning is not very necessary, and it also takes time to drive the brushes and high-pressure nozzles to reset, resulting in low efficiency of filter plate cleaning. When cleaning filter plate 2, the device first moves the filter plate 2 to be cleaned into the sliding frame 5, and then starts the first drive mechanism and cleaning mechanism on both sides. The first drive mechanism can drive the cleaning mechanism to move downwards from the upper part of the filter plate 2 or downwards from the lower part of the filter plate 2 through the docking mechanism. The side position moves upward; when the upper first drive mechanism drives the cleaning mechanism to the middle position of the filter plate 2 through the docking mechanism on its surface, the cleaning mechanism will dock with the docking mechanism on the surface of the lower first drive mechanism, and the docking mechanism on the upper position that docks with the cleaning mechanism will directly release the cleaning mechanism; at this time, the upper and lower first drive mechanisms will start to reset, and the lower first drive mechanism will drive the cleaning mechanism to move downward to the bottom position of the filter plate 2, while the upper first drive mechanism will move to the upper position of the filter plate 2. After the cleaning mechanism moves from the upper position to the bottom position of the filter plate 2, it completes one cleaning of the filter plate 2; at this time, it can be driven The cleaned filter plate 2 is removed, and at the same time, the first motor 6 drives the threaded rod 7 to rotate. When the threaded rod 7 rotates, it drives the sliding frame 5 to slide to the right, and then drives the next filter plate 2 to move to the cleaning position to the left. When the next filter plate 2 is in the cleaning position, the first motor 6 is stopped, and then the first drive mechanism and cleaning mechanism on the upper and lower sides are driven again to clean the filter plate 2. This device cleans the filter plate 2 by driving the cleaning mechanism to move from one side of the filter plate 2 to the other side. At the same time, the first drive mechanism that drives the cleaning mechanism to move the cleaning does not obstruct the movement of the filter plate 2, so as to achieve the effect of quickly cleaning the next filter plate 2, which can effectively improve the cleaning efficiency of the filter plate 2.

[0033] As a further embodiment of the present invention, the cleaning mechanism includes a water tank 8, a water spray pipe 9, and a brush 10. The brush 10 is fixedly connected to the water spray pipe 9. Multiple high-pressure nozzles 11 are evenly fixedly connected to the surface of the water spray pipe 9 on both the upper and lower sides of the brush 10, and first connectors 12 are symmetrically fixedly connected to the upper and lower sides of the water spray pipe 9. The water tank 8 is fixedly connected to the sliding frame 5, and water supply pipes 13 are symmetrically fixedly connected to the upper and lower surfaces of the water tank 8. During operation, when the filter plate 2 needs to be cleaned, the water spray pipe 9 can be moved by the first driving mechanism on both the upper and lower sides and the docking mechanism on the surface of the first driving mechanism. When the water spray pipe 9 moves, it will drive the brush 10 on its surface to move. When the brush 10 moves to the position of contacting the filter plate 2, the water tank 8 is activated. The water tank 8 will fill the water supply pipes 13 on both the upper and lower sides with water. The water is transported to the water spray pipe 9 through the water supply pipe 13 and finally sprayed out through the high-pressure nozzles 11 on the surface of the water spray pipe 9. With the help of the brush 10, the filter plate 2 can be cleaned.

[0034] As a further embodiment of the present invention, the first driving mechanism includes a first sliding plate 14, which is slidably connected to the sliding frame 5, and a reciprocating lead screw 15 is symmetrically rotatably connected to the front and rear sides of the surface of the first sliding plate 14; a sliding rod 16 is symmetrically fixedly connected to the front and rear sides of the surface of the first sliding plate 14, and a second sliding plate 17 is slidably connected to the surface of the sliding rod 16, with the second sliding plate 17 threadedly engaged with the reciprocating lead screw 15; a second driving mechanism is provided on the surface of the first sliding plate 14, which is used to drive the brush 10 to move laterally reciprocally when the brush 10 moves vertically to clean the filter plate 2, thereby improving the cleaning effect of the cleaning mechanism; during operation, by driving the upper and lower sides... When the reciprocating screw 15 rotates on the surface of the first sliding plate 14, the upper reciprocating screw 15 will drive the second sliding plate 17 on its surface to move downward, and the lower reciprocating screw 15 will drive the second sliding plate 17 on its surface to move upward. When the upper second sliding plate 17 moves downward, it will drive the water spray pipe 9 and the brush 10 to move downward through the docking mechanism. When the water spray pipe 9 docks with the docking mechanism on the surface of the lower second sliding plate 17, the upper docking mechanism is released from the water spray pipe 9. At the same time, the upper and lower second sliding plates 17 begin to reset under the action of the reciprocating screw 15. The lower second sliding plate 17 drives the water spray pipe 9 to move downward to the bottom position of the filter plate 2.

[0035] As a further embodiment of the present invention, the second driving mechanism includes a second motor 18, which is fixedly connected to the sliding frame 5, and a first synchronous pulley 19 is fixedly connected to the front end of the output shaft of the second motor 18. A first synchronous belt 20 is provided on the surface of the first synchronous pulley 19, and second synchronous pulleys 21 are symmetrically arranged on the upper and lower sides of the first synchronous pulley 19. The second synchronous pulleys 21 are rotatably connected to the sliding frame 5, and the first synchronous belt 20 simultaneously meshes with the first synchronous pulley 19 and the two second synchronous pulleys 21. A telescopic rod 22 is fixedly connected to the front end of the second synchronous pulley 21, and a first bevel gear 23 is fixedly connected to the front end of the telescopic rod 22. The reciprocating lead screw 15 at the rear position...

Two third synchronous pulleys 25 are rotatably connected to the upper and lower surfaces of the first sliding plate 14, respectively. The two third synchronous pulleys 25 are fixedly connected to two reciprocating lead screws 15. A second synchronous belt 26 is provided on the surface of the third synchronous pulley 25, and the second synchronous belt 26 meshes with both third synchronous pulleys 25 simultaneously. A connecting rod 27 is rotatably connected to the edge of the surface of the third synchronous pulley 25, and the other end of the connecting rod 27 is rotatably connected to the sliding frame 5. During operation, when it is necessary to drive the water spray pipe 9 to move for cleaning... When filter plate 2 is in operation, starting the second motor 18 can drive the first synchronous pulley 19 to rotate. The first synchronous pulley 19, through the first synchronous belt 20, can drive the second synchronous pulleys 21 on both sides to rotate. When the second synchronous pulleys 21 rotate, they will drive the telescopic rod 22 to rotate. The telescopic rod 22 will drive the first bevel gear 23 to rotate. The first bevel gear 23 will drive the reciprocating screw 15 at the rear position to rotate through the second bevel gear 24. When the reciprocating screw 15 at the rear position rotates, it will drive the third synchronous pulley 25 connected to it to rotate. When the third synchronous pulley 25 rotates, it will drive the third synchronous pulley 25 at the front side to rotate through the second synchronous belt 26. The step wheel 25 drives the reciprocating screw 15 at the front to rotate. When the reciprocating screws 15 on both the front and rear sides rotate, they drive the second sliding plate 17 to move up and down. When the third synchronous wheel 25 on both the front and rear sides rotates, the third synchronous wheel 25 can drive the first sliding plate 14 to slide back and forth on the surface of the sliding frame 5 through the connecting rod 27 on its surface. When the first sliding plate 14 moves back and forth, it will drive the second sliding plate 17 to move back and forth through the sliding rod 16. The second sliding plate 17 will drive the water spray pipe 9 and the brush 10 to move back and forth, thereby further improving the cleaning effect of the brush 10 and the rinsing effect of the high-pressure nozzle 11.

[0036] As a further embodiment of the present invention, the docking mechanism includes four first connecting rods 28, which are distributed in the front, back, left, and right positions on the surface of the second sliding plate 17 and are all fixedly connected to the second sliding plate 17. A sleeve 29 is slidably connected to the upper and lower first connecting rods 28, close to each other on one side. A first spring 30 is fitted onto the surface of the sleeve 29, with one end of the first spring 30 fixedly connected to the sleeve 29 and the other end fixedly connected to the first connecting rod 28. A first slot 31 is formed on the surface of the sleeve 29, and a second connecting rod 32 is slidably connected inside the sleeve 29. The second connecting rod 32 is fixedly connected to the water spray pipe 9. A first locking block 33 is slidably connected to the surface of the second connecting rod 32. The first locking block 33 is open to... The second spring 34 is connected to the second connecting rod 32, and the first locking block 33 is engaged with the first locking groove 31. During operation, when the second sliding plate 17 at the upper position moves downward, it will drive the four first connecting rods 28 on its surface to move downward. When the first connecting rods 28 move downward, they will drive the sleeve 29 to move downward through the first spring 30. When the sleeve 29 moves downward, the sleeve 29 at the bottom position will drive the water spray pipe 9 to move upward. When the sleeve 29 at the bottom position drives the water spray pipe 9 to the middle position of the filter plate 2, the sleeve 29 at the upper position is just fitted onto the second connecting rod 32 on the upper surface of the water spray pipe 9, and the first locking block 33 on the surface of the second connecting rod 32 is just locked in the first locking groove 31 on the surface of the upper sleeve 29.
