Description

Technical Field

[0001] This invention relates to the field of filter press equipment technology, specifically to a device for cleaning filter plates that stick to filter presses. Background Technology

[0002] To separate sludge from liquids in wastewater or oily wastewater, filter presses are often used. The sludge accumulates in filter plates to form a filter cake, thus separating and filtering the liquid. The working principle of a current filter press is as follows: An oil pump is started, causing the piston rod to move the filter plates inwards, gradually compressing them. Then, a feed pump is started to deliver the liquid to the filter plates. During filtration, the liquid flows out of the filter plates, while solid residue is blocked by the plates, remaining between the two plates to form a filter cake. A plate-pulling machine is then started to open the filter plates, and the filter cake falls downwards under gravity. When filtering highly viscous sludge or oily wastewater, due to the viscosity and liquid flow, some sludge is directly squeezed out. When sludge is pressed onto the filter plate, the molecular density between sludge particles increases, causing it to adhere to the filter plate and become unable to detach. During the operation of the plate-pulling machine, the lower part of the sludge detaches due to gravity, while the upper part remains stuck due to its stickiness. Alternatively, the lower part may remain stuck due to viscosity, resulting in the entire clump adhering to the filter plate. This requires manual removal, and the plate-pulling machine can only open the filter plates one by one, leading to a longer cleaning time and increased operating time. Furthermore, the sludge adsorbed on the filter plate can clog the pores, causing the filtration efficiency to gradually decrease after a period of use. This significantly reduces the filtration effect of the sludge, thus affecting the overall working efficiency of the equipment.

[0003] Therefore, we propose a filter plate sticking removal device for filter presses. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a filter plate clump cleaning device for filter presses, which solves the problem of long cleaning time for clumps on filter plates in current filter presses, leading to a reduction in the overall working efficiency of the filter press.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a filter plate sticking cleaning device for a filter press, comprising a filter press box and a slag discharge box located at the bottom of the filter press box, wherein an installation groove is provided at the bottom of the inner wall of the filter press box, and a movable bottom plate is provided inside the installation groove; wherein a plurality of filter pressing mechanisms are provided inside the filter press box, and the plurality of filter pressing mechanisms are all located at the top of the movable bottom plate and are equidistantly distributed.

[0008] The filter press mechanism includes a fixed frame, a filter press frame, and a filter plate. The fixed frame is located at the top of the inner wall of the filter press box, and the filter press frame is located at the bottom of the fixed frame. A connecting block is located at the top of the filter press frame, and both ends of the connecting block are rotatably located inside the fixed frame. A filter plate is located on one side inside the filter press frame, and a cleaning mechanism is also located inside the filter press frame, and the cleaning mechanism is movably located on one side of the filter plate.

[0009] The cleaning mechanism includes a cleaning frame and a cleaning brush. Electric sliding tables are provided on both sides of the inner wall of the filter press frame, and mounting blocks are provided on one side of each of the two electric sliding tables. The cleaning frame is provided between the two mounting blocks, and the cleaning brush is provided inside the cleaning frame. An air guide frame is also provided on the top of the cleaning frame, and an air guide channel is provided inside the air guide frame. Miniature air pumps are provided on both sides of the top of the cleaning frame, and the air outlets of the two miniature air pumps are connected to the interior of the air guide channel through air guide pipes. Several pressurizing nozzles are provided on one side of the air guide frame, and the interiors of the pressurizing nozzles are connected to the interior of the air guide channel.

[0010] Two electric sliding platforms drive the cleaning frame to move up and down on one side of the filter plate. The cleaning brush, which is in contact with one side of the filter plate, removes the sticky residue on the filter plate. A micro air pump introduces air into the air guide frame, and then a pressurized nozzle sprays the air from inside the air guide frame onto one side of the filter plate to blow off the sticky residue, further improving the cleaning effect on the filter plate.

[0011] Preferably, both sides of the filter press are provided with conveying pipes, and the interior of both conveying pipes is connected to the interior of the filter press. A slag outlet is also provided on one side of the bottom of the slag discharge box, and the bottom of the inner wall of the slag discharge box is set as a slope with the left side higher than the right side.

[0012] Preferably, the filter press frame has movable grooves on both sides inside, and movable blocks are slidably arranged inside the two movable grooves. A first fixed rod is arranged inside the two movable grooves, and a first spring is sleeved on the surface of the two first fixed rods.

[0013] Preferably, each of the two movable blocks has a through hole that mates with the first fixed rod, and one end of each of the two first fixed rods is slidably connected to the interior of the two through holes.

[0014] Preferably, both movable blocks are provided with sliders at their bottoms, and the movable base plate has a groove inside that cooperates with the slider, with the bottom of the slider sliding inside the groove.

[0015] Preferably, servo electric cylinders are provided on both sides of the inner wall of the slag discharge box, and two fixed blocks are provided on one side of the bottom of the movable base plate. The drive ends of the two servo electric cylinders are respectively rotatably connected to the inside of the two fixed blocks. The drive ends of the servo electric cylinders drive one side of the movable base plate to move downward, so that the movable base plate is in an inclined state. At the same time as the movable base plate moves downward, the slider at the bottom of the movable block slides to one side inside the slide groove. At this time, the connecting block at the top of the filter press rotates inside the fixed frame, so that the filter press always maintains a right angle with the movable base plate. The filter press is in an inclined state, and the side of the filter plate with the filter cake sticky block is facing down.

[0016] Preferably, hexagonal blocks are provided on both sides of the inner wall of the cleaning frame, and one side of each hexagonal block is rotatably connected to the inner wall of the cleaning frame. A torsion spring is provided on one side of each hexagonal block, and one end of each torsion spring is connected to the inner wall of the cleaning frame.

[0017] Preferably, a servo motor is installed inside the mounting block, and the output end of the servo motor extends into the interior of the hexagonal block. An internal gear ring is installed inside the hexagonal block, and a gear block is installed at the output end of the servo motor. The surface of the gear block meshes with the inner wall of the internal gear ring, wherein the gear block is a quarter gear. The output end of the servo motor drives the gear block to rotate inside the hexagonal block. When the surface of the gear block meshes with the inner wall of the internal gear ring, the hexagonal block rotates under the drive of the gear block. At this time, the torsion spring twists, generating elastic potential energy. Then, the gear block disengages from the internal gear ring. Under the action of the elastic potential energy of the torsion spring, the hexagonal block rotates in the opposite direction to reset. Therefore, when the servo motor is working, the hexagonal block rotates periodically at a fixed angle on one side of the inner wall of the cleaning frame.

[0018] Preferably, the cleaning brush has grooves on both sides, and each of the two grooves has a locking block inside, and each of the two locking blocks has a slot that matches the hexagonal block.

[0019] Preferably, a second fixing rod is also provided on one side of the inner wall of the groove, and a second spring is sleeved on the surface of the second fixing rod. One end of the second fixing rod is slidably connected to the inside of the locking block, wherein one end of the second spring is connected to one side of the inner wall of the groove, and the other end of the second spring is connected to one side of the locking block. When assembling the cleaning brush and the cleaning frame, the locking block is pressed into the groove of the groove to allow the hexagonal block to enter the slot inside the locking block. Then the locking block is released, and the locking block is reset under the action of the second spring, thus completing the quick assembly between the cleaning brush and the cleaning frame. The hexagonal block drives the cleaning brush to swing up and down on one side of the filter plate, which not only avoids the adhesion of sticky objects on the cleaning brush, but also improves the cleaning effect of the cleaning brush on the sticky objects on the filter plate.

[0020] (III) Beneficial Effects

[0021] This invention provides a device for cleaning filter plate clumps in a filter press. Compared with the prior art, it has the following advantages:

[0022] (1) By setting a rotatable filter press frame inside the filter press box, the bottom of the filter press frame is driven by a movable base plate. When cleaning the filter plate clumps, the movable base plate is controlled to flip downwards. The bottom of the two movable blocks in the filter press frame extends out from the inside of the filter press frame, so that a material passage gap is created between the bottom of the filter press frame and the upper end of the movable base plate. At the same time, the movable base plate drives the filter press frame to tilt inside the filter press box. Under the action of the clumps' own weight, the clumps on the filter plate on the filter pressing side automatically fall down. The cleaning mechanism set on the other side of the filter plate is used to efficiently clean the clumps on the filter plate. The cleaning brush that contacts one side of the filter plate removes the clumps attached to the filter plate. Air is introduced into the air guide frame with a micro air pump. Then, the air inside the air guide frame is sprayed to one side of the filter plate with a booster nozzle to blow off the clumps on the filter plate, further improving the cleaning effect of the clumps on the filter plate.

[0023] (2) By changing the position of the filter plate, the adhesive blocks on the filter plate are quickly cleaned by the gravity of the adhesive blocks themselves, the contact cleaning by the cleaning brush, and the air blowing treatment by the pressurized nozzle. The adhesive blocks that are cleaned off fall onto the movable base plate and slide into the slag discharge box along the upper surface of the inclined movable base plate. Finally, the adhesive blocks are collected through the slag outlet. Through the combined treatment of multiple methods, the adhesive blocks on the filter plate are cleaned efficiently, which greatly shortens the cleaning time of the filter plate and ensures that the filter plate maintains a good filtration effect during the working process, thus significantly improving the working efficiency of the entire filter press.

[0024] (3) By controlling the cleaning brush to swing up and down at a fixed angle inside the cleaning frame periodically, the sticky block is prevented from adhering to the surface of the cleaning brush, and the cleaning effect of the cleaning brush on the filter plate can be effectively improved; by using the flexible assembly between the card block and the hexagonal block, the cleaning brush can be easily replaced inside the cleaning frame.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 3As shown, the present invention proposes a technical solution: a filter plate clumping cleaning device for a filter press, comprising a filter press chamber 10 and a slag discharge box 20 located at the bottom of the filter press chamber 10. An installation groove 30 is formed at the bottom of the inner wall of the filter press chamber 10, and a movable bottom plate 40 is provided inside the installation groove 30. One side of the movable bottom plate 40 is rotatably connected to the inner wall of the installation groove 30, and a sealing ring is fitted around the periphery of the movable bottom plate 40 to ensure that the material can undergo normal filter pressing treatment inside the filter press chamber 10. The internal structure is equipped with several filter pressing mechanisms, which are equidistantly distributed on the top of the movable base plate 40. Both sides of the filter pressing box 10 are equipped with conveying pipes 50, and the interior of both conveying pipes 50 is connected to the interior of the filter pressing box 10. The bottom of the slag discharge box 20 is also equipped with a slag outlet 60. The bottom of the inner wall of the slag discharge box 20 is set as a slope with the left side higher than the right side. When the filter cake sticky block enters the interior of the slag discharge box 20, under the action of gravity, the filter cake sticky block slides along the slope to the interior of the slag outlet 60.

[0038] It should be noted that when the material is fed into the filter press box 10 through two conveying pipes 50 for filter pressing, the material moves from one side to the other inside the filter press box 10 and passes through multiple filter pressing mechanisms to complete the filter pressing process. At this time, filter cake clumps are left in the filter pressing mechanism, and the clumps in the filter pressing mechanism need to be cleaned in time to ensure that the filter pressing mechanism can achieve normal and efficient filter pressing effect on the material.

[0039] Please see Figure 4 As shown, the filter press mechanism includes a fixed frame 11, a filter press frame 12, and a filter plate 13. The fixed frame 11 is located at the top of the inner wall of the filter press box 10, and the filter press frame 12 is located at the bottom of the fixed frame 11. A connecting block 14 is located at the top of the filter press frame 12, and both ends of the connecting block 14 are rotatably located inside the fixed frame 11. A filter plate 13 is located on one side inside the filter press frame 12. A cleaning mechanism is also located inside the filter press frame 12, and the cleaning mechanism is movably located on one side of the filter plate 13.

[0040] Please see Figure 6As shown, the cleaning mechanism includes a cleaning frame 21 and a cleaning brush 22. Electric sliding tables 23 are provided on both sides of the inner wall of the filter press 12, and mounting blocks 24 are provided on one side of each of the two electric sliding tables 23. The cleaning frame 21 is positioned between the two mounting blocks 24, and the cleaning brush 22 is installed inside the cleaning frame 21. One side of the cleaning brush 22 contacts one side of the filter plate 13, and the movement of the cleaning brush 22 on one side of the filter plate 13 enables rapid cleaning of the adhering clumps on the filter plate 13. An air guide frame 25 is also provided on the top of the cleaning frame 21, and the air guide frame 25... The unit is equipped with an air guide channel. Both sides of the top of the cleaning frame 21 are equipped with micro air pumps 26, and the air outlets of the two micro air pumps 26 are connected to the interior of the air guide channel through air guide pipes. Several pressurized nozzles 27 are provided on one side of the air guide frame 25, and the interiors of the pressurized nozzles 27 are connected to the interior of the air guide channel. The air outlets of the pressurized nozzles 27 are all facing one side of the filter plate 13. The air sprayed from the pressurized nozzles 27 blows off the sticky blocks on the filter plate 13, further improving the cleaning effect of the sticky blocks on the filter plate 13.

[0041] Please see Figure 5 As shown, movable grooves 15 are provided on both sides inside the filter press frame 12, and movable blocks 16 are slidably arranged inside the two movable grooves 15. First fixed rods 17 are provided inside the two movable grooves 15, and first springs 18 are sleeved on the surface of the two first fixed rods 17. One end of the first spring 18 is connected to the top of the inner wall of the movable groove 15, and the other end of the first spring 18 is connected to the top of the movable block 16. Through holes 19 that cooperate with the first fixed rods 17 are provided inside the two movable blocks 16, and one end of the two first fixed rods 17 is slidably connected to the inside of the two through holes 19 respectively.

[0042] Both movable blocks 16 are provided with sliders 110 at their bottoms. The movable base plate 40 has a groove 111 inside that cooperates with the sliders 110, and the bottom of the sliders 110 is located inside the groove 111 and slides.

[0043] Please see Figure 7 As shown, servo cylinders 28 are provided on both sides of the inner wall of the slag discharge box 20. Two fixed blocks 29 are provided on one side of the bottom of the movable base plate 40. The drive ends of the two servo cylinders 28 are respectively rotatably connected to the inside of the two fixed blocks 29. The drive ends of the two servo cylinders 28 drive one side of the movable base plate 40 to rotate downward through the fixed blocks 29, so that the movable base plate 40 is tilted as a whole. At this time, the inside of the filter press box 10 and the inside of the slag discharge box 20 are connected to each other through the mounting groove 30.

[0044] It should be noted that after the material is filtered by the filter press mechanism, the drive end of the servo electric cylinder 28 drives one side of the movable base plate 40 to move downward, so that the movable base plate 40 is in an inclined state. At the same time as the movable base plate 40 moves downward, the slider 110 at the bottom of the movable block 16 slides to one side inside the slide groove 111. At this time, the connecting block 14 at the top of the filter press frame 12 rotates inside the fixed frame 11, so that the filter press frame 12 always maintains a right angle with the movable base plate 40. The filter press frame 12 is in an inclined state, and the side of the filter cake adhering to the filter plate 13 faces downward.

[0045] Furthermore, since the top of the filter press frame 12 is limited by the fixed frame 11, when the movable base plate 40 is flipped downwards, the bottom of the two movable blocks 16 in the filter press frame 12 extends out from the inside of the filter press frame 12, and a material passage gap is generated between the bottom of the filter press frame 12 and the upper end face of the movable base plate 40. Under the action of the weight of the sticky block itself, the sticky block on the filter plate 13 on the filter pressing side automatically falls down, and the cleaning mechanism on the other side of the filter plate 13 efficiently cleans the sticky block on the filter plate 13.

[0046] Two electric sliding tables 23 drive the cleaning frame 21 to move up and down on one side of the filter plate 13. The cleaning brush 22, which is in contact with one side of the filter plate 13, removes the sticky residue on the filter plate 13. The micro air pump 26 introduces air into the air guide frame 25. Then, the pressurized nozzle 27 sprays the air inside the air guide frame 25 towards one side of the filter plate 13 to blow off the sticky residue on the filter plate 13, further improving the cleaning effect on the sticky residue on the filter plate 13.

[0047] By utilizing the gravity of the sticky blocks themselves, the contact cleaning of the cleaning brush 22, and the air blowing treatment of the pressurized nozzle 27, the sticky blocks on the filter plate 13 are quickly cleaned. The cleaned-off sticky blocks fall onto the movable base plate 40 and slide along the upper surface of the inclined movable base plate 40 into the slag discharge box 20. Finally, the sticky blocks are collected through the slag outlet 60. Through the combined treatment of multiple methods, the sticky blocks on the filter plate 13 are efficiently cleaned, the cleaning time of the filter plate 13 is greatly shortened, the filter plate 13 is guaranteed to maintain a good filtration effect during operation, and the working efficiency of the entire filter press is significantly improved.

[0048] Furthermore, to further improve the cleaning effect of the cleaning mechanism on the adhering clumps on filter plate 13, please refer to... Figures 8 to 10As shown, hexagonal blocks 31 are provided on both sides of the inner wall of the cleaning frame 21, and one side of each hexagonal block 31 is rotatably connected to the inner wall of the cleaning frame 21. A torsion spring 32 is provided on one side of each hexagonal block 31, and one end of each torsion spring 32 is connected to the inner wall of the cleaning frame 21. A servo motor 33 is installed inside the mounting block 24, and the output end of the servo motor 33 extends into the interior of the hexagonal block 31. An internal gear ring 34 is installed inside the hexagonal block 31, and a gear block 35 is installed at the output end of the servo motor 33. The surface of the gear block 35 meshes with the inner wall of the internal gear ring 34 for transmission. The gear block 35 is a quarter gear. The output end of the servo motor 33 drives the gear block 35 to rotate inside the hexagonal block 31. When the surface of the gear block 35 meshes with the inner wall of the internal gear ring 34, the hexagonal block 31 rotates under the drive of the gear block 35. At this time, the torsion spring 32 is twisted, generating elastic potential energy. Then the gear block 35 disengages from the internal gear ring 34. Under the action of the elastic potential energy of the torsion spring 32, the hexagonal block 31 rotates in the opposite direction to reset. Therefore, when the servo motor 33 is working, the hexagonal block 31 rotates periodically at a fixed angle on one side of the inner wall of the cleaning frame 21.

[0049] The cleaning brush 22 has grooves 36 on both sides, and each groove 36 contains a locking block 37. Each locking block 37 has a slot 38 that mates with a hexagonal block 31. A second fixing rod 39 is also provided on one side of the inner wall of the groove 36, and a second spring 310 is fitted onto the surface of the second fixing rod 39. One end of the second fixing rod 39 is slidably connected to the inside of the locking block 37, while one end of the second spring 310 is connected to one side of the inner wall of the groove 36, and the other end of the second spring 310 is connected to one side of the locking block 37. When assembling the cleaning brush 22 and the cleaning frame 21, the hexagonal block 31 is inserted into the slot 38 inside the hexagonal block 37 by pressing the locking block 37 into the groove 36. Then, the locking block 37 is released and reset under the action of the second spring 310, thus completing the quick assembly between the cleaning brush 22 and the cleaning frame 21. The hexagonal block 31 drives the cleaning brush 22 to swing up and down on one side of the filter plate 13, which not only prevents the cleaning brush 22 from having any sticky residue, but also improves the cleaning effect of the cleaning brush 22 on the sticky residue on the filter plate 13.

[0050] For further details, please refer to Figures 1 to 10 As shown, this invention also discloses a method for operating a filter plate sticking removal device for a filter press, the specific steps of which are as follows:

[0051] Step 1: The material is fed into the filter press box 10 through two conveying pipes 50 for filter pressing. The material moves from one side to the other inside the filter press box 10, and the filter cake clumps are left on one side of the filter plate 13.

[0052] Step 2: The drive end of the servo electric cylinder 28 drives one side of the movable base plate 40 to move downward, so that the movable base plate 40 is in an inclined state. At the same time, the slider 110 at the bottom of the movable block 16 slides to one side inside the slide groove 111. At this time, the connecting block 14 at the top of the filter press frame 12 rotates inside the fixed frame 11, so that the filter press frame 12 always maintains a right angle with the movable base plate 40. The filter press frame 12 is in an inclined state, and the side of the filter cake sticky block on the filter plate 13 faces downward.

[0053] Step 3: When one side of the movable base plate 40 is flipped downward, the bottom of the two movable blocks 16 in the filter press frame 12 extends out from the inside of the filter press frame 12, and a material passage gap is generated between the bottom of the filter press frame 12 and the upper end face of the movable base plate 40. Under the action of the weight of the sticky block itself, the sticky block on the filter plate 13 on the filter pressing side automatically falls down.

[0054] Step 4: The cleaning frame 21 is driven by two electric sliding tables 23 to move up and down on one side of the filter plate 13. At the same time, the output end of the servo motor 33 drives the cleaning brush 22 to rotate 90° periodically inside the cleaning frame 21 through the hexagonal block 31. The cleaning brush 22, which is in contact with one side of the filter plate 13, removes the sticky residue on the filter plate 13. The micro air pump 26 introduces air into the air guide frame 25. Then, the pressurized nozzle 27 sprays the air inside the air guide frame 25 towards one side of the filter plate 13 to blow off the sticky residue on the filter plate 13.
