Description

Technical Field

[0001] This invention relates to the field of paint waste treatment technology, and in particular to a UV paint waste filtration device. Background Technology

[0002] UV coatings are coatings that are cured using UV radiation. UV-cured coatings can be applied to ink printing and exposed to UV irradiation. Their solid content can be as high as 100%, therefore they have no volatile components and do not pollute the environment. The high solid content also allows them to be used in very thin films. Coating residue is an emission product of coating glass, plastics, wood, aluminum beverage bottles, and other objects.

[0003] The existing technology for treating coating residue still has the following problems:

[0004] 1. In the existing technology, when the filter screen is clogged during the filtration of paint residue, it is impossible to stop the injection of paint residue in time and clean the filter screen in time, resulting in a large accumulation of paint residue on the filter screen. This not only affects the cleaning of the filter screen later but also reduces the filtration efficiency of the paint residue.

[0005] 2. In the process of filtering paint residue, it can only filter the filter residue, which is a single function and cannot be further processed by washing the filter residue.

[0006] To address the above-mentioned problems, this invention proposes a UV coating waste filtration device. Summary of the Invention

[0007] This invention provides a UV coating waste filtration device, which solves the shortcomings of the prior art, which cannot stop the injection of coating residue in time when the filter screen is clogged and cannot clean the filter screen in time, and can only filter the residue, resulting in a single function.

[0008] This invention provides the following technical solution:

[0009] A UV coating waste filtration device includes: a filter box, a filter residue box fixedly connected to one side of the filter box, and a liquid inlet pipe fixedly passing through the side of the filter box away from the filter residue box.

[0010] The filter structure, located inside the filter box, is used to filter the filter residue liquid;

[0011] A sealing structure is installed inside the filter box to promptly seal the inlet pipe;

[0012] The cleaning structure, located inside the filter box, is used to collect filter residue.

[0013] In one possible design, the filtration structure includes multiple inclined plates fixedly connected within a filter box, rising sequentially from left to right. A base plate is located at the top of each inclined plate, and a filter plate is fixedly connected to the top of the base plate. Each filter plate has multiple filter holes. A fixing pin is fixedly connected within the filter box. Sliding grooves are provided on the inner walls of the filter box on opposite sides. Sliding rods are slidably connected within two of the sliding grooves. A collar is fitted onto the outer walls of both the sliding rods and the fixing pin. A fine gauze layer is detachably attached to the side of the two collars closest to each other. Filter liquid is continuously injected into the filter box through an inlet pipe. The filter liquid moves to the left along the inclined plates, and the inner diameter of the filter holes on the multiple filter plates gradually decreases. Thus, as the filter liquid passes through the multiple inclined plates and filter plates, the filter residue in the filter liquid is filtered step by step. The filtered liquid falls onto the fine gauze layer for further filtration.

[0014] In one possible design, the sealing structure includes a fixed block slidably connected to the inner wall of the filter box on the side away from the filter cake box. A sliding plate is fixedly connected to the side of the fixed block near the fixed pin, and the top of the sliding plate slides through the rightmost inclined plate. A protrusion is fixedly connected to the inner wall of the filter box on the side away from the filter cake box. The top of the protrusion is elastically connected to the bottom of the fixed block by multiple springs. A connecting rod is rotatably connected to the side of the sliding plate near the filter cake box, and the bottom end of the connecting rod is rotatably connected to the sliding rod. A pusher is fixedly connected to the side of the sliding plate near the filter cake box. When multiple filter plates are blocked, the liquid falling on the fine gauze layer gradually decreases. When the speed of the liquid flowing into the fine gauze layer is less than the speed of the liquid passing through the fine gauze layer, the elastic force of the spring pushes the sliding plate upward. The sliding plate drives the connecting rod to rotate, and the connecting rod drives the sliding rod to move away from the fixed pin. As the sliding plate moves upward, the sliding plate gradually blocks the liquid inlet pipe, and the amount of filter cake liquid entering the filter box through the liquid inlet pipe gradually decreases.

[0015] In one possible design, the cleaning structure includes a rotating groove on one side of the filter box, a first rotating shaft rotatably connected within the rotating groove, a rotating plate fixedly sleeved on the outer wall of the first rotating shaft, and two torsion springs sleeved on the outer wall of the first rotating shaft. The ends of the two torsion springs that are close to each other are fixedly connected to the rotating plate, and the ends of the two torsion springs that are far apart from each other are respectively fixedly connected to the inner wall of one side of the rotating groove. The bottom of the rotating plate is fixedly connected to the top of multiple filter plates. Lifting plates are slidably connected to the inner walls of the filter cake box on the far side. Multiple L-shaped striking plates are fixedly connected to the top of the lifting plates, and the multiple L-shaped striking plates correspond to the corresponding bottom plates. An arc hook releases the brake on the rotating plate, and the rotating plate rotates counterclockwise under the stored force of the torsion spring. The rotating plate drives the multiple filter plates and bottom plates to rotate above the filter cake box until the bottom plates collide with the tops of the L-shaped striking plates, initially striking the filter plates and bottom plates and shaking off the filter cake on the filter plates and bottom plates.

[0016] In one possible design, the bottom of the rightmost inclined plate is provided with a groove, and a rotating rod is rotatably connected in the groove. An arc-shaped hook is fixedly connected to the end of the rotating rod away from the liquid inlet pipe. The bottom of the rotating plate is provided with a hook groove that engages with the arc-shaped hook. A tension spring is fixedly connected to the inner wall of the top of the groove, and the bottom end of the tension spring is fixedly connected to the top side of the rotating rod. When the sliding plate and the push block move upward, the push block pushes the rotating rod to rotate counterclockwise, the tension spring begins to stretch, and the rotating rod drives the arc-shaped hook to disengage from the hook groove, releasing the brake on the rotating plate. This facilitates the rotating plate to drive the filter plate and the bottom plate to rotate counterclockwise, shaking the filter residue on the filter plate and the bottom plate into the filter residue box.

[0017] In one possible design, a rotating shaft rotates through the filter cake box. Two cams located below a lifting plate are fixedly fitted onto the outer wall of the rotating shaft, and the cams cooperate with the lifting plate. A U-shaped plate is fixedly connected inside the filter cake box, and two slide rails are fixedly connected inside the U-shaped plate. A movable frame is slidably connected to the top of the slide rails, and the movable frame has a rectangular hole. A pin that mates with the rectangular hole is fixedly connected to the side of the cam that is off-center. Fixed plates are fixedly connected to both rectangular holes, and a second rotating shaft is fixedly connected to the side of the two fixed plates that are close to each other. The two rotating shafts are rotatably connected to the same crushing wheel at their close ends. A drive motor is fixedly connected to one side of the filter cake box, and the output shaft of the drive motor is fixedly connected to one end of the rotating shaft. When the drive motor is started, it drives the cam to rotate through the rotating shaft. The cam pushes the lifting plate and the L-shaped striking plate to move up and down reciprocally, further causing the filter plate and the bottom plate to vibrate and shake the filter cake off the filter plate. In addition, the cam drives the moving frame to move back and forth through the pin shaft. The moving frame drives the crushing wheel to roll back and forth on the U-shaped plate through the fixed plate, thereby crushing the filter cake on the U-shaped plate, which is convenient for further processing of the filter cake later.

[0018] In one possible design, a guide plate is fixedly connected to the inner wall of the filter box near the filter cake box. The guide plate can guide the filter cake liquid left on the inclined plate, so that the fine gauze layer can filter the filter cake liquid again.

[0019] In one possible design, a pressure sensor is fixedly connected to the top of each L-shaped striking plate, and the pressure sensor is electrically connected to the drive motor. When the bottom plate collides with the top of the L-shaped striking plate, it initially strikes the filter plate and the bottom plate, which can shake off the filter residue on the filter plate and the bottom plate. At this time, the pressure sensor on the top of the L-shaped striking plate receives the pressure signal and transmits the signal to the drive motor, which starts the drive motor and further drives the filter plate and the bottom plate to vibrate, shaking off the filter residue on the filter plate.

[0020] In one possible design, the inner diameter of the filter holes in multiple filter plates gradually decreases from right to left. The filter residue liquid can be filtered step by step through the filter holes with different inner diameters in multiple filter plates, avoiding the filter residue liquid from clogging the filter plates all at once.

[0021] In one possible design, a nut is fixedly connected inside the filter box, and a round rod passes through the nut. The outer wall of the round rod has external threads, which are threaded to the nut. Multiple stirring rods located inside the filter box are fixedly connected to the outer wall of the round rod, and the stirring rods are located below the fine gauze layer. The end of the round rod away from the filter box extends into the filter cake box and is fixedly connected to a U-shaped connecting frame. The end of the U-shaped connecting frame away from the filter box is fixedly connected to two movable frames. When the movable frames move back and forth to crush the filter cake, the movable frames drive the round rod to move back and forth. Since the external threads are threaded to the nut, the round rod and the stirring rods can rotate when the round rod moves back and forth. Thus, the stirring rods can drive the fine gauze layer to vibrate up and down, further accelerating the drying of the fine gauze layer. In addition, it can also shake off the filter cake attached to the fine gauze layer, making it easier to remove the fine gauze layer from the collar and clean the filter cake on the fine gauze layer later. The fine gauze layer can be reused.

[0022] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0023] In this invention, a sliding plate is fixedly connected to the side of the fixed block near the fixed pin. The protrusion is elastically connected to the fixed block by multiple springs. A connecting rod is rotatably connected to the side of the sliding plate near the filter cake box, and the bottom end of the connecting rod is rotatably connected to the sliding rod. A pusher is fixedly connected to the side of the sliding plate near the filter cake box. When multiple filter plates are blocked, the liquid on the fine gauze layer gradually decreases. The elastic force of the spring pushes the sliding plate to move upward, and the connecting rod drives the sliding rod to move away from the fixed pin. As the sliding plate moves upward, the sliding plate gradually blocks the liquid inlet pipe, and the amount of filter cake liquid entering the filter box through the liquid inlet pipe gradually decreases.

[0024] In this invention, a rotating rod is rotatably connected inside the groove, and an arc-shaped hook is fixedly connected to one end of the rotating rod. The bottom of the rotating plate is provided with a hook groove, and a tension spring is fixedly connected to the top inner wall of the groove. The bottom end of the tension spring is fixedly connected to one side of the top of the rotating rod. When the sliding plate and the push block move up to block the liquid inlet pipe, the push block pushes the rotating rod to rotate counterclockwise, the tension spring begins to stretch, and the rotating rod drives the arc-shaped hook to disengage from the hook groove, releasing the brake on the rotating plate. This facilitates the rotating plate to drive the filter plate and the bottom plate to rotate counterclockwise, shaking the filter residue on the filter plate and the bottom plate into the filter residue box, thus automatically completing the cleaning task of the filter plate.

[0025] In this invention, a fixing pin is fixedly connected inside the filter box. Sliding grooves are provided on the inner walls of the filter box on opposite sides. A sliding rod is slidably connected within each of the two sliding grooves. A collar is fitted onto the outer walls of both the sliding rod and the fixing pin. A fine gauze layer is detachably mounted on the side of the two collars that are close to each other. The sliding rod and the sliding plate are rotatably connected via a connecting rod. When the filter plate is unobstructed, a large amount of filter residue accumulates on the fine gauze layer, which in turn moves the sliding rod to the left, causing the sliding plate to move downwards and release the blockage of the inlet pipe. Conversely, when there is little filter residue on the fine gauze layer, the sliding rod resets under the elastic force of the spring, and the sliding plate gradually closes the inlet pipe. The amount of filter residue entering the filter box gradually decreases, facilitating subsequent cleaning of the filter plate.

[0026] In this invention, two cams located below the lifting plate are fixedly sleeved on the outer wall of the rotating shaft. A movable frame is slidably connected to the top of the slide rail. A pin that mates with a rectangular hole is fixedly connected to the side of the cam that is offset away from the cam. A fixed plate is fixedly connected to each of the two rectangular holes. A crushing wheel is rotatably connected between the two fixed plates through a second rotating shaft. The rotating shaft drives the cam to rotate, and the cam pushes the lifting plate and the L-shaped striking plate to move up and down reciprocally, causing the filter plate and the bottom plate to vibrate and shake off the filter residue on the filter plate. In addition, the cam drives the movable frame to move back and forth through the pin. The movable frame drives the crushing wheel to roll back and forth on the U-shaped plate through the fixed plate, thereby crushing the filter residue on the U-shaped plate, which is convenient for further processing of the filter residue later.

[0027] In this invention, during the filtration of the filter residue liquid, when the filter plate becomes clogged, the amount of filter residue liquid accumulated on the fine gauze layer gradually decreases to gradually close the inlet pipe. This facilitates the cleaning of the filter plate later, preventing excessive filter residue liquid from remaining on the inclined plate. In addition, when the inlet pipe is blocked, the brake on the rotating plate is automatically released, allowing the filter plate and the bottom plate to rotate to the top of the filter residue box, facilitating the cleaning of the filter plate and the one-step processing of the filter residue.

[0045] Example 1

[0046] Reference Figure 1 and Figure 2This embodiment of a UV coating waste filtration device includes: a filter box 1, a filter residue box 2 fixedly connected to one side of the filter box 1 by bolts, an inlet pipe 3 fixedly passing through the side of the filter box 1 away from the filter residue box 2, a filtration structure, set inside the filter box 1, used to filter the filter residue liquid, a sealing structure, set inside the filter box 1, used to promptly seal the inlet pipe 3, a cleaning structure, set inside the filter box 1, used to collect the filter residue, and a guide plate 8 fixedly connected to the inner wall of the side of the filter box 1 near the filter residue box 2 by bolts. The guide plate 8 can guide the filter residue liquid left on the inclined plate 4, so that the fine gauze layer 13 filters the filter residue liquid again.

[0047] Reference Figure 3 and Figure 4 The filtration structure includes multiple inclined plates 4 that are bolted together and rise sequentially from left to right within the filter box 1. A base plate 6 is located at the top of each inclined plate 4, and a filter plate 5 is bolted to the top of the base plate 6. Multiple filter holes 7 are located within the filter plate 5. A fixing pin 9 is bolted to the filter box 1. Sliding grooves 10 are provided on the inner walls of the sides of the filter box 1 that are far apart from each other. Sliding rods 11 are slidably connected within the two sliding grooves 10. A collar 12 is fitted onto the outer walls of both the sliding rod 11 and the fixing pin 9. A fine gauze layer 13 is detachably attached to the side of the two collars 12 that are close to each other. Filter residue liquid is continuously injected into the filter box 1 through the inlet pipe 3. The filter residue liquid moves to the left along the inclined plates 4, and the inner diameter of the filter holes 7 on the multiple filter plates 5 gradually decreases. Thus, as the filter residue liquid passes through the multiple inclined plates 4 and the filter plates 5, the filter residue in the filter residue liquid is filtered step by step. The filtered liquid falls onto the fine gauze layer 13 for further filtration.

[0048] Reference Figure 3 and Figure 4 The inner diameter of the filter holes 7 in the multiple filter plates 5 gradually decreases from right to left. The filter residue liquid can be filtered step by step through the filter holes 7 with different inner diameters in the multiple filter plates 5, so as to avoid the filter residue liquid clogging the filter plates 5 at one time.

[0049] Reference Figure 6The sealing structure includes a fixed block 16 slidably connected to the inner wall of the filter box 1 on the side away from the filter cake box 2. A sliding plate 14 is bolted to the side of the fixed block 16 near the fixed pin 9, and the top of the sliding plate 14 slides through the rightmost inclined plate 4. A protrusion 17 is bolted to the inner wall of the filter box 1 on the side away from the filter cake box 2. The top of the protrusion 17 is elastically connected to the bottom of the fixed block 16 by multiple springs 18. A connecting rod 15 is rotatably connected to the side of the sliding plate 14 near the filter cake box 2, and the bottom end of the connecting rod 15 is rotatably connected to the sliding rod 11. A pusher block 19 is bolted to the side of the filter cake box 2. When multiple filter plates 5 are blocked, the liquid falling on the fine gauze layer 13 gradually decreases. When the speed of the liquid flowing into the fine gauze layer 13 is less than the speed of the liquid passing through the fine gauze layer 13, the elastic force of the spring 18 pushes the sliding plate 14 to move upward. The sliding plate 14 drives the connecting rod 15 to rotate. The connecting rod 15 drives the sliding rod 11 to move away from the fixed pin 9. As the sliding plate 14 moves upward, the sliding plate 14 gradually blocks the liquid inlet pipe 3, and the amount of filter cake liquid entering the filter cake box 1 through the liquid inlet pipe 3 gradually decreases.

[0050] Reference Figure 3 , Figure 4 and Figure 7 The cleaning structure includes a rotating groove 23 located on one side of the filter box 1. A first rotating shaft 24 is rotatably connected within the rotating groove 23. A rotating plate 25 is fixedly sleeved on the outer wall of the first rotating shaft 24. Two torsion springs 26 are sleeved on the outer wall of the first rotating shaft 24. The ends of the two torsion springs 26 that are close to each other are fixedly connected to the rotating plate 25, and the ends of the two torsion springs 26 that are far apart from each other are fixedly connected to the inner wall of one side of the rotating groove 23. The bottom of the rotating plate 25 is fixedly connected to the top of multiple filter plates 5 by bolts. The inner wall of the filter cake box 2 on the side that is far apart from each other... A lifting plate 28 is slidably connected to each other. Multiple L-shaped striking plates 29 are fixedly connected to the top of the lifting plate 28 by bolts. The multiple L-shaped striking plates 29 correspond to the corresponding bottom plates 6. The arc hook 22 releases the brake on the rotating plate 25. The rotating plate 25 rotates counterclockwise under the stored force of the torsion spring 26. The rotating plate 25 drives multiple filter plates 5 and bottom plates 6 to rotate above the filter cake box 2 until the bottom plate 6 collides with the top of the L-shaped striking plates 29, initially striking the filter plates 5 and bottom plates 6 and shaking off the filter cake on the filter plates 5 and bottom plates 6.

[0051] Reference Figure 5The bottom of the rightmost inclined plate 4 is provided with a groove 20. A rotating rod 21 is rotatably connected in the groove 20. The end of the rotating rod 21 away from the liquid inlet pipe 3 is fixedly connected to an arc hook 22 by bolts. The bottom of the rotating plate 25 is provided with a hook groove 27 that engages with the arc hook 22. A tension spring 45 is fixedly connected to the top inner wall of the groove 20, and the bottom end of the tension spring 45 is fixedly connected to the top side of the rotating rod 21. When the sliding plate 14 and the push block 19 move upward, the push block 19 pushes the rotating rod 21 to rotate counterclockwise, the tension spring 45 begins to stretch, and the rotating rod 21 drives the arc hook 22 to disengage from the hook groove 27, releasing the brake on the rotating plate 25. This facilitates the rotating plate 25 to drive the filter plate 5 and the bottom plate 6 to rotate counterclockwise, shaking the filter residue on the filter plate 5 and the bottom plate 6 into the filter residue box 2.

[0052] Reference Figure 7 and Figure 8 A rotating shaft 30 is rotatably inserted inside the filter cake box 2. Two cams 32 located below the lifting plate 28 are fixedly fitted on the outer wall of the rotating shaft 30, and the cams 32 cooperate with the lifting plate 28. A U-shaped plate 33 is fixedly connected inside the filter cake box 2 by bolts. Two slide rails 34 are fixedly connected inside the U-shaped plate 33 by bolts. A movable frame 35 is slidably connected to the top of the slide rails 34. The movable frame 35 has a rectangular hole 36. A pin 37 that cooperates with the rectangular hole 36 is fixedly connected to the side of the cam 32 that is off-center by bolts. A fixed plate 38 is fixedly connected to each of the two rectangular holes 36 by bolts. A second rotating shaft 39 is fixedly connected to the side of the two fixed plates 38 that is close to each other by bolts. The two second rotating shafts 39 are close to each other. One end of the filter cake box 2 is rotatably connected to the same crushing wheel 40. The drive motor 31 is fixedly connected to one side of the filter cake box 2 by bolts. The output shaft of the drive motor 31 is fixedly connected to one end of the rotating shaft 30 by a coupling. When the drive motor 31 is started, the drive motor 31 drives the cam 32 to rotate through the rotating shaft 30. The cam 32 pushes the lifting plate 28 and the L-shaped striking plate 29 to move up and down reciprocally, which further drives the filter plate 5 and the bottom plate 6 to vibrate, shaking off the filter cake on the filter plate 5. In addition, the cam 32 drives the moving frame 35 to move back and forth through the pin 37. The moving frame 35 drives the crushing wheel 40 to roll back and forth on the U-shaped plate 33 through the fixed plate 38, thereby crushing the filter cake on the U-shaped plate 33, which is convenient for further processing of the filter cake in the later stage.

[0053] Reference Figure 7 Each L-shaped striking plate 29 has a pressure sensor fixedly connected to its top by bolts, and the pressure sensor is electrically connected to the drive motor 31. When the bottom plate 6 collides with the top of the L-shaped striking plate 29, it initially strikes the filter plate 5 and the bottom plate 6, which can shake off the filter residue on the filter plate 5 and the bottom plate 6. At this time, the pressure sensor on the top of the L-shaped striking plate 29 receives the pressure signal and transmits the signal to the drive motor 31, which starts the drive motor 31 and further drives the filter plate 5 and the bottom plate 6 to vibrate, shaking off the filter residue on the filter plate 5.

[0055] Reference Figure 1 and Figure 2 This embodiment of a UV coating waste filtration device includes: a filter box 1, a filter residue box 2 fixedly connected to one side of the filter box 1 by bolts, an inlet pipe 3 fixedly passing through the side of the filter box 1 away from the filter residue box 2, a filtration structure, set inside the filter box 1, used to filter the filter residue liquid, a sealing structure, set inside the filter box 1, used to promptly seal the inlet pipe 3, a cleaning structure, set inside the filter box 1, used to collect the filter residue, and a guide plate 8 fixedly connected to the inner wall of the side of the filter box 1 near the filter residue box 2 by bolts. The guide plate 8 can guide the filter residue liquid left on the inclined plate 4, so that the fine gauze layer 13 filters the filter residue liquid again.

[0056] Reference Figure 3 and Figure 4 The filtration structure includes multiple inclined plates 4 that are bolted together and rise sequentially from left to right within the filter box 1. A base plate 6 is located at the top of each inclined plate 4, and a filter plate 5 is bolted to the top of the base plate 6. Multiple filter holes 7 are located within the filter plate 5. A fixing pin 9 is bolted to the filter box 1. Sliding grooves 10 are provided on the inner walls of the sides of the filter box 1 that are far apart from each other. Sliding rods 11 are slidably connected within the two sliding grooves 10. A collar 12 is fitted onto the outer walls of both the sliding rod 11 and the fixing pin 9. A fine gauze layer 13 is detachably attached to the side of the two collars 12 that are close to each other. Filter residue liquid is continuously injected into the filter box 1 through the inlet pipe 3. The filter residue liquid moves to the left along the inclined plates 4, and the inner diameter of the filter holes 7 on the multiple filter plates 5 gradually decreases. Thus, as the filter residue liquid passes through the multiple inclined plates 4 and the filter plates 5, the filter residue in the filter residue liquid is filtered step by step. The filtered liquid falls onto the fine gauze layer 13 for further filtration.

[0057] Reference Figure 3 and Figure 4 The inner diameter of the filter holes 7 in the multiple filter plates 5 gradually decreases from right to left. The filter residue liquid can be filtered step by step through the filter holes 7 with different inner diameters in the multiple filter plates 5, so as to avoid the filter residue liquid clogging the filter plates 5 at one time.

[0058] Reference Figure 6The sealing structure includes a fixed block 16 slidably connected to the inner wall of the filter box 1 on the side away from the filter cake box 2. A sliding plate 14 is bolted to the side of the fixed block 16 near the fixed pin 9, and the top of the sliding plate 14 slides through the rightmost inclined plate 4. A protrusion 17 is bolted to the inner wall of the filter box 1 on the side away from the filter cake box 2. The top of the protrusion 17 is elastically connected to the bottom of the fixed block 16 by multiple springs 18. A connecting rod 15 is rotatably connected to the side of the sliding plate 14 near the filter cake box 2, and the bottom end of the connecting rod 15 is rotatably connected to the sliding rod 11. A pusher block 19 is bolted to the side of the filter cake box 2. When multiple filter plates 5 are blocked, the liquid falling on the fine gauze layer 13 gradually decreases. When the speed of the liquid flowing into the fine gauze layer 13 is less than the speed of the liquid passing through the fine gauze layer 13, the elastic force of the spring 18 pushes the sliding plate 14 to move upward. The sliding plate 14 drives the connecting rod 15 to rotate. The connecting rod 15 drives the sliding rod 11 to move away from the fixed pin 9. As the sliding plate 14 moves upward, the sliding plate 14 gradually blocks the liquid inlet pipe 3, and the amount of filter cake liquid entering the filter cake box 1 through the liquid inlet pipe 3 gradually decreases.

[0059] Reference Figure 3 , Figure 4 and Figure 7 The cleaning structure includes a rotating groove 23 located on one side of the filter box 1. A first rotating shaft 24 is rotatably connected within the rotating groove 23. A rotating plate 25 is fixedly sleeved on the outer wall of the first rotating shaft 24. Two torsion springs 26 are sleeved on the outer wall of the first rotating shaft 24. The ends of the two torsion springs 26 that are close to each other are fixedly connected to the rotating plate 25, and the ends of the two torsion springs 26 that are far apart from each other are fixedly connected to the inner wall of one side of the rotating groove 23. The bottom of the rotating plate 25 is fixedly connected to the top of multiple filter plates 5 by bolts. The inner wall of the filter cake box 2 on the side that is far apart from each other... A lifting plate 28 is slidably connected to each other. Multiple L-shaped striking plates 29 are fixedly connected to the top of the lifting plate 28 by bolts. The multiple L-shaped striking plates 29 correspond to the corresponding bottom plates 6. The arc hook 22 releases the brake on the rotating plate 25. The rotating plate 25 rotates counterclockwise under the stored force of the torsion spring 26. The rotating plate 25 drives multiple filter plates 5 and bottom plates 6 to rotate above the filter cake box 2 until the bottom plate 6 collides with the top of the L-shaped striking plates 29, initially striking the filter plates 5 and bottom plates 6 and shaking off the filter cake on the filter plates 5 and bottom plates 6.

[0060] Reference Figure 5The bottom of the rightmost inclined plate 4 is provided with a groove 20. A rotating rod 21 is rotatably connected in the groove 20. The end of the rotating rod 21 away from the liquid inlet pipe 3 is fixedly connected to an arc hook 22 by bolts. The bottom of the rotating plate 25 is provided with a hook groove 27 that engages with the arc hook 22. A tension spring 45 is fixedly connected to the top inner wall of the groove 20, and the bottom end of the tension spring 45 is fixedly connected to the top side of the rotating rod 21. When the sliding plate 14 and the push block 19 move upward, the push block 19 pushes the rotating rod 21 to rotate counterclockwise, the tension spring 45 begins to stretch, and the rotating rod 21 drives the arc hook 22 to disengage from the hook groove 27, releasing the brake on the rotating plate 25. This facilitates the rotating plate 25 to drive the filter plate 5 and the bottom plate 6 to rotate counterclockwise, shaking the filter residue on the filter plate 5 and the bottom plate 6 into the filter residue box 2.

[0061] Reference Figure 7 and Figure 8 A rotating shaft 30 is rotatably inserted inside the filter cake box 2. Two cams 32 located below the lifting plate 28 are fixedly fitted on the outer wall of the rotating shaft 30, and the cams 32 cooperate with the lifting plate 28. A U-shaped plate 33 is fixedly connected inside the filter cake box 2 by bolts. Two slide rails 34 are fixedly connected inside the U-shaped plate 33 by bolts. A movable frame 35 is slidably connected to the top of the slide rails 34. The movable frame 35 has a rectangular hole 36. A pin 37 that cooperates with the rectangular hole 36 is fixedly connected to the side of the cam 32 that is off-center by bolts. A fixed plate 38 is fixedly connected to each of the two rectangular holes 36 by bolts. A second rotating shaft 39 is fixedly connected to the side of the two fixed plates 38 that is close to each other by bolts. The two second rotating shafts 39 are close to each other. One end of the filter cake box 2 is rotatably connected to the same crushing wheel 40. The drive motor 31 is fixedly connected to one side of the filter cake box 2 by bolts. The output shaft of the drive motor 31 is fixedly connected to one end of the rotating shaft 30 by a coupling. When the drive motor 31 is started, the drive motor 31 drives the cam 32 to rotate through the rotating shaft 30. The cam 32 pushes the lifting plate 28 and the L-shaped striking plate 29 to move up and down reciprocally, which further drives the filter plate 5 and the bottom plate 6 to vibrate, shaking off the filter cake on the filter plate 5. In addition, the cam 32 drives the moving frame 35 to move back and forth through the pin 37. The moving frame 35 drives the crushing wheel 40 to roll back and forth on the U-shaped plate 33 through the fixed plate 38, thereby crushing the filter cake on the U-shaped plate 33, which is convenient for further processing of the filter cake in the later stage.

[0062] Reference Figure 7 Each L-shaped striking plate 29 has a pressure sensor fixedly connected to its top by bolts, and the pressure sensor is electrically connected to the drive motor 31. When the bottom plate 6 collides with the top of the L-shaped striking plate 29, it initially strikes the filter plate 5 and the bottom plate 6, which can shake off the filter residue on the filter plate 5 and the bottom plate 6. At this time, the pressure sensor on the top of the L-shaped striking plate 29 receives the pressure signal and transmits the signal to the drive motor 31, which starts the drive motor 31 and further drives the filter plate 5 and the bottom plate 6 to vibrate, shaking off the filter residue on the filter plate 5.

[0063] Reference Figure 9 and Figure 10 A nut 43 is bolted into the filter box 1, through which a round rod 41 passes. The outer wall of the round rod 41 has an external thread 44, which is threaded into the nut 43. Multiple stirring rods 42 located within the filter box 1 are bolted to the outer wall of the round rod 41, positioned below the fine gauze layer 13. The end of the round rod 41 away from the filter box 1 extends into the filter cake box 2 and is bolted to a U-shaped connecting frame 46. The end of the U-shaped connecting frame 46 away from the filter box 1 is fixedly connected to two movable frames 35. When the filter cake is crushed by moving back and forth, the moving frame 35 drives the round rod 41 to move back and forth. Since the external thread 44 is threadedly connected to the nut 43, the round rod 41 and the stirring rod 42 can rotate when the round rod 41 moves back and forth. Thus, the stirring rod 42 can drive the fine gauze layer 13 to vibrate up and down, further accelerating the drying of the fine gauze layer 13. In addition, it can also shake off the filter cake attached to the fine gauze layer 13, making it easier to remove the fine gauze layer 13 from the collar 12 and clean the filter cake on the fine gauze layer 13 later. The fine gauze layer 13 can be reused.

[0064] Working principle: Filter liquid is continuously injected into the filter box 1 through the inlet pipe 3. The filter liquid moves to the left along the inclined plate 4, and the inner diameter of the filter holes 7 on the multiple filter plates 5 gradually decreases. Thus, as the filter liquid passes through the multiple inclined plates 4 and filter plates 5, the filter residue in the filter liquid is filtered step by step. The filtered liquid is guided by the guide plate 8 and falls onto the fine gauze layer 13. Since the filter holes 7 were not blocked before, the liquid flow rate on the fine gauze layer 13 is relatively high, and a large amount of liquid accumulates on the fine gauze layer 13. The fine gauze layer 13 begins to fall downwards, and the liquid is further filtered through the fine gauze layer 13. In addition, when falling downwards, it drives the slide rod 11 to move along the trajectory of the slide groove 10 towards the fixed pin 9. The slide rod 11 drives the connecting rod 15 to rotate. Link 15 drives sliding plate 14 and fixed block 16 to move downwards, and spring 18 begins to compress. When sliding plate 14 moves downwards, it can release the blockage of inlet pipe 3. At this time, the outlet of inlet pipe 3 gradually expands, and the amount of filter residue liquid entering the filter box 1 through inlet pipe 3 gradually increases. When multiple filter plates 5 are blocked, the filter residue liquid entering the filter box 1 through inlet pipe 3 is gradually blocked by filter plates 5, and the liquid falling on fine gauze layer 13 gradually decreases. When the speed of liquid flowing into fine gauze layer 13 is less than the speed of liquid passing through fine gauze layer 13, the liquid on fine gauze layer 13 gradually decreases. The elastic force of spring 18 pushes fixed block 16, sliding plate 14 and push block 19 upwards. Sliding plate 14 drives link 15 to rotate, and link 15 drives slide rod 11 to move away from the filter box 13. As the fixed pin 9 moves upward, and the sliding plate 14 moves upward, it gradually blocks the inlet pipe 3, thus reducing the amount of filter residue liquid entering the filter box 1 through the inlet pipe 3. Additionally, as the sliding plate 14 and push block 19 move upward, push block 19 pushes the rotating rod 21 to rotate counterclockwise, and tension spring 45 begins to stretch. The rotating rod 21 drives the arc-shaped hook 22 to disengage from the hook groove 27, releasing the brake on the rotating plate 25. The rotating plate 25 then rotates counterclockwise under the stored force of the torsion spring 26. The rotating plate 25 drives multiple filter plates 5 and the bottom plate 6 to rotate above the filter residue box 2 until the bottom plate 6 collides with the top of the L-shaped striking plate 29, initially striking the filter plates 5 and the bottom plate 6, shaking off the filter residue. At this point, the top of the L-shaped striking plate 29... The pressure sensor receives the pressure signal and transmits it to the drive motor 31, activating the drive motor 31. The drive motor 31 drives the cam 32 to rotate via the rotating shaft 30. The cam 32 pushes the lifting plate 28 and the L-shaped striking plate 29 to move up and down reciprocally, further causing the filter plate 5 and the bottom plate 6 to vibrate, shaking off the filter residue on the filter plate 5. In addition, the cam 32 drives the moving frame 35 to move back and forth via the pin shaft 37. The moving frame 35 drives the rolling wheel 40 to roll back and forth on the U-shaped plate 33 via the fixed plate 38, thereby crushing the filter residue on the U-shaped plate 33 for further processing. The back and forth movement of the moving frame 35 drives the round rod 41 to move back and forth via the U-shaped connecting frame 46. Since the external thread 44 is threadedly connected to the nut 43,As the circular rod 41 moves back and forth, both the circular rod 41 and the stirring rod 42 can rotate. This allows the stirring rod 42 to drive the fine gauze layer 13 to vibrate up and down, further accelerating the drying of the fine gauze layer 13. Additionally, it shakes off the filter residue adhering to the fine gauze layer 13, making it easier to remove the fine gauze layer 13 from the collar 12 and clean the filter residue. The fine gauze layer 13 can be reused.
