Description
Technical Field
[0001] The present invention relates to the technical field of wastewater treatment, and in particular to industrial desulfurization wastewater treatment equipment and process. Background Art
[0002] In the process of industrial desulfurization wastewater treatment, filter press is a common solid-liquid separation equipment, which is widely used in the treatment of desulfurization wastewater. Among them, diaphragm filter press is a device used for solid-liquid separation. Its working principle is to filter and press through a diaphragm to improve the dryness and filtration efficiency of the filter cake.
[0003] When the diaphragm filter press starts working, the filter plate and filter cloth in the filter chamber are tightly pressed together to form a closed filter chamber; the suspension to be treated (such as industrial desulfurization wastewater) is pumped into the filter chamber, the liquid passes through the filter cloth, and the solid particles are trapped on the surface of the filter cloth, gradually forming a filter cake; as the solid-liquid separation proceeds, the filter cake in the filter chamber gradually becomes thicker, and the filtrate is discharged through the filter cloth. At this time, the moisture content in the filter cake is still high and needs further dehydration; after the initial filtration is completed, the diaphragm filter press starts the pressing function of the diaphragm. The diaphragm is usually located inside the filter plate. When the system starts the diaphragm pressing, compressed air or hydraulic oil is injected behind the diaphragm to expand the diaphragm and apply additional pressure to the filter cake; this process can further squeeze the moisture in the filter cake, thereby increasing the dryness of the filter cake; after the pressing is completed, the filter press opens the filter plate, and the filter cake is discharged or pushed out of the filter chamber by a mechanical device. At this time, the moisture content of the filter cake has been significantly reduced, which is suitable for further treatment or direct disposal.
[0004] The traditional diaphragm filter press applies pressure to allow the liquid to pass through the filter cloth, and the solid particles are trapped on the filter cloth to form a filter cake. However, the solid matter in the filter cake may have a certain viscosity. These substances may have a strong adhesion to the surface of the filter cloth during the filtration process, making it difficult to completely separate from the filter cloth during unloading. As a result, some materials are likely to adhere to the filter cloth during unloading. On the one hand, the adhered materials are likely to cause the filter cloth to be blocked. On the other hand, if the adhered materials are located in the fitting position between two adjacent filter plates, the filter chamber may not be sealed tightly during the filtration process, causing material leakage or mud inclusion. In addition, in order to prevent the filter cloth from being blocked, the filter cloth needs to be cleaned. However, the traditional diaphragm filter press usually needs to be shut down to clean the filter cloth on the filter plate, which is likely to affect the operating efficiency and unloading effect of the diaphragm filter press. Summary of the invention
[0005] In view of the fact that some materials are easily adhered to the filter cloth during unloading in the prior art, if the adhered materials are located at the fitting position between two adjacent filter plates, the filter chamber may not be sealed tightly during the filter press process, thereby causing material leakage or mud inclusion, an industrial desulfurization wastewater treatment equipment and process are proposed.
[0006] In one aspect of the present application, an industrial desulfurization wastewater treatment device is provided, the purpose of which is to effectively treat the material adhering to the filter cloth by shaking the filter plate left and right and intermittently scraping the filter cloth, so as to effectively separate the filter cake from the filter cloth.

[0008] Furthermore, the connecting assembly includes a threaded hole opened on one side of the filter plate, a T-shaped stud arranged inside the threaded hole, a sleeve frame sleeved on the rod wall of the T-shaped stud, a mounting groove opened on the outer wall of the sleeve frame, a T-shaped block elastically installed inside the mounting groove, a slot opened on the outer wall of the sleeve frame for inserting the T-shaped block, and a pull rod arranged on the outer wall of the T-shaped block.
[0009] Furthermore, the connecting assembly also includes a compression spring arranged on the inner wall of the mounting groove, and one end of the compression spring is fixedly connected to the inner wall of the mounting groove, and the other end of the compression spring is fixedly connected to the outer wall of the T-shaped block.
[0010] Furthermore, a guide block is provided on the rod wall of the connecting rod, and a guide groove for the guide block to slide is provided on the movable end of the electric push rod.
[0011] Furthermore, the control component includes a first fixed plate arranged on the wall of the connecting rod, a first rotating rod arranged on the outer wall of the cross rod, a first cam arranged at one end of the first rotating rod for pushing the first fixed plate, and a first driving motor arranged on the outer wall of the cross rod, and the output shaft of the first driving motor is fixedly connected to the other end of the first rotating rod; the control component also includes a second fixed plate arranged on the wall of the sealing cylinder, a second rotating rod arranged on the outer wall of the cross rod, a second cam arranged at one end of the second rotating rod for pushing the second fixed plate, and a second driving motor arranged on the outer wall of the cross rod, and the output shaft of the second driving motor is fixedly connected to the other end of the second rotating rod.
[0012] Furthermore, the control component also includes a mounting frame arranged on the top surface of the cross bar, a reciprocating screw arranged inside one of the mounting frames, a sliding rod arranged inside the remaining mounting frames, and a connecting frame arranged on the outer wall of the scraper, and multiple scrapers are connected by the connecting frame, the outer wall of the connecting frame is threadedly connected to the outer wall of the reciprocating screw, and the outer wall of the connecting frame is slidably connected to the rod wall of the sliding rod, and the connecting frame can be driven to realize reciprocating lifting by controlling the rotation of the reciprocating screw.
[0013] Furthermore, a third rotating rod is provided on the outer wall of the cross rod, and the rod wall of the first rotating rod is connected to the rod wall of the third rotating rod through gear transmission, and the bottom end of the reciprocating screw rod is connected to the rod wall of the third rotating rod through a bevel gear transmission.
[0014] Furthermore, the scraper includes a first sharp portion, a curved portion, and a second sharp portion.
[0015] Furthermore, the present invention also provides an industrial desulfurization wastewater treatment process, comprising the following steps:
[0016] By controlling the active end of the electric push rod to extend, multiple filter plates are pushed in sequence until the sealing cylinder and the baffle come into conflict, and the filter cloths between the multiple filter plates are tightly fitted, the industrial desulfurization wastewater is injected into the grouting pipe to perform solid-liquid separation treatment on the industrial desulfurization wastewater;
[0017] After the wastewater treatment is completed, the active end of the electric push rod is controlled to retract, and the multiple filter plates are pulled apart to the maximum distance in sequence. After the filter cake falls from the middle of the multiple filter plates, it falls on the material conveying mechanism for transmission;
[0018] Through the control component, multiple filter plates can be synchronously driven to slide left and right. At the same time, the control component drives the scraper to move up and down. When the scraper scrapes on the surface of the filter cloth, the shaking of the filter plate can more effectively peel off the material attached to the surface of the filter cloth.
[0019] After the filter cloth surface is cleaned, the control component controls the multiple filter plates and scrapers to return to their initial positions.
[0020] Beneficial effects of the present invention:
[0021] 1. The control components are used to control multiple filter plates to slide left and right synchronously, which can effectively loosen the materials adhering to the filter cloth. There are two scrapers arranged back to back between two adjacent filter plates, one of which is in contact with the surface of the filter cloth, and the other is not in contact with the surface of the filter cloth, providing sliding space for multiple filter plates. By shaking the filter plates left and right and intermittently scraping the filter cloth, the materials adhering to the filter cloth can be effectively handled, the filter cake can be effectively separated from the filter cloth, and the particles attached to the surface of the filter cloth can be more effectively peeled off.
[0022] 2. When the scraper is scraping on the surface of the filter cloth, the left and right shaking of the filter plate can make the force of the scraper on the filter cloth more impactful and joint, and simultaneously exert force in the up and down and left and right directions on the particles attached to the surface of the filter cloth, so as to more effectively peel off the particles attached to the surface of the filter cloth. Compared with the prior art that directly uses a scraper for scraping, the part of the attached material embedded in the holes of the filter cloth is still easy to remain inside the filter cloth, and the present device is conducive to peeling off the part of the attached material embedded in the holes of the filter cloth. Compared with the prior art that directly uses a high-pressure water gun to wash the filter cloth, it is necessary to shut down the wastewater treatment equipment and dry the filter cloth, which is not convenient for frequent use. When the present device is in use, the material attached to the filter cloth can be processed after the unloading is completed, and there is no need to frequently wash and dry the filter cloth, which effectively improves the operation efficiency and unloading effect of the diaphragm filter press.
[0023] 3. When the scraper descends, the first sharp portion is used to help the scraper scrape up the material attached to the surface of the filter cloth from top to bottom. The inverted portion can apply downward pressure to the scraped material, which is conducive to the scraped material falling downward. When the scraper rises, the second sharp portion is used to help the scraper scrape up the material attached to the surface of the filter cloth from bottom to top.
[0024] 4. When people need to disassemble and replace one of the filter plates, by pulling the pull rod, the T-shaped block can be driven into the inside of the installation groove, and then the T-shaped block squeezes the compression spring, so that the compression spring is compressed to store elastic force. At this time, people can remove the sleeve frame from the T-shaped stud. By removing the sleeve frame on one of the filter plates, one of the filter plates can be separated, and then one of the filter plates can be taken out upwards for disassembly and replacement.

DETAILED DESCRIPTION
[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0042] Example 1, reference Figure 1-Figure 14 , which is the first embodiment of the present invention, provides an industrial desulfurization wastewater treatment equipment, including a support base 1, a cross bar 2 fixedly installed on the top of the support base 1, and a filter plate 3 with through holes slidably installed on the top surface of the cross bar 2, and a plurality of filter plates 3 are provided, and also include a filter cloth 6 fixedly installed on the opposite surfaces of two adjacent filter plates 3, a drainage pipe 5 fixedly installed on one side of the filter plate 3, filter holes 4 opened on the opposite surfaces of two adjacent filter plates 3 and connected with the inside of the drainage pipe 5, an air hole 8 opened on the side of the filter plate 3 away from the drainage pipe 5, and a diaphragm 7 fixedly installed on the opposite surfaces of two adjacent filter plates 3 and connected with the inside of the air hole 8, and the outer wall of the filter cloth 6 is fixedly connected to the inner wall of the through hole of the filter plate 3.
[0043] Specifically, in actual use, a material conveying mechanism is installed at the bottom of the cross bar 2. The material conveying mechanism can be a conveyor belt. When the filter cake falls from the middle of the filter plate 3, it falls on the material conveying mechanism for transmission. The air hole 8 conveys compressed air through the air pipe and the valve, and the compressed air is injected into the diaphragm 7 through the air hole 8 to expand the diaphragm 7, which can apply additional pressure to the filter cake and further squeeze the moisture in the filter cake. The two sides of the filter plate 3 are fixedly installed with mounting plates, so that the filter plate 3 can be mounted on the top surface of the two cross bars 2 to slide.
[0044] When two adjacent filter plates 3 are squeezed against each other, the filter cloth 6 between the two adjacent filter plates 3 fits tightly, and the industrial desulfurization wastewater is injected into the middle of the two adjacent filter cloths 6, and then the solid particles in the industrial desulfurization wastewater are trapped in the two adjacent filter cloths 6, gradually forming a filter cake, and the filtered water can be discharged from the drain pipe 5 through the filter holes 4. Then, after the preliminary filtration is completed, compressed air is injected into the diaphragm 7 through the air holes 8, so that the diaphragm 7 expands and applies additional pressure to the filter cake, further squeezing the moisture in the filter cake, thereby improving the dryness of the filter cake.
[0045] Reference Figure 1-Figure 4An electric push rod 10 is fixedly installed on the top of the support seat 1, and a connecting rod 11 is slidably installed on the movable end of the electric push rod 10, and the end of the connecting rod 11 away from the electric push rod 10 is fixedly connected to the outer wall of one of the filter plates 3 located on the outside, a grouting pipe 9 is fixedly installed on the top of the support seat 1, and a sealing cylinder 12 is slidably installed on the end of the grouting pipe 9, and the end of the sealing cylinder 12 away from the grouting pipe 9 is fixedly connected to the outer wall of another filter plate 3 located on the outside, a baffle 34 for blocking the sealing cylinder 12 is fixedly installed on the top of the support seat 1, and multiple filter plates 3 are connected by a connecting assembly 13.
[0046] Specifically, by setting the baffle 34, when the device is treating industrial desulfurization wastewater, under the push of the electric push rod 10, the sealing cylinder 12 and the baffle 34 collide with each other, and the sealing cylinder 12 cannot continue to move away from the electric push rod 10, which further improves the stability of the device when in use and ensures the tight squeezing between the multiple filter plates 3. Since the position of the grouting pipe 9 is fixed and the grouting pipe 9 is interlocked with the sealing cylinder 12, the distance that the sealing cylinder 12 can move toward the electric push rod 10 is fixed, and the sealing cylinder 12 is slidably fitted with the grouting pipe 9 to ensure the sealing of material flow. The electric push rod 10 can be a linear electric push rod in the prior art. By controlling the active end of the electric push rod 10 to contract, multiple filter plates 3 can be pulled apart in turn. By controlling the active end of the electric push rod 10 to extend, the electric push rod 10 can push the connecting rod 11, and the connecting rod 11 pushes the multiple filter plates 3 in turn until the sealing cylinder 12 conflicts with the baffle 34. The filter cloth 6 between the multiple filter plates 3 fits tightly, and industrial desulfurization wastewater can be injected into the grouting pipe 9.
[0047] Reference Figure 1-Figure 14 A scraper 15 for scraping the outer wall of the filter cloth 6 is slidably installed on the top of the support seat 1; a control component 14 is provided on the top of the support seat 1. The function of the control component 14 is to synchronously drive multiple filter plates 3 to shake left and right to loosen the solid particles attached to the filter cloth 6, and at the same time drive the scraper 15 to rise and fall to intermittently scrape the outer wall of the filter cloth 6, so as to effectively peel off the particles attached to the surface of the filter cloth 6.
[0048] Specifically, there are two scrapers 15 arranged back to back between two adjacent filter plates 3. The multiple filter plates 3 are connected by a connecting assembly 13. The multiple filter plates 3 are controlled by a control component 14 to slide left and right synchronously, which can effectively loosen the material adhered to the filter cloth 6. In order to adapt to the left and right sliding of multiple filter plates 3, one of the two scrapers 15 arranged back to back between two adjacent filter plates 3 contacts the surface of the filter cloth 6, and the other does not contact the surface of the filter cloth 6, thereby providing sliding space for multiple filter plates 3.
[0049] Reference Figure 5-Figure 7The connecting component 13 includes a threaded hole 16 opened on one side of the filter plate 3, a T-shaped stud 17 installed inside the threaded hole 16 through internal and external threads, a sleeve frame 18 sleeved on the rod wall of the T-shaped stud 17, a mounting groove 19 opened on the outer wall of the sleeve frame 18, a T-shaped block 20 elastically installed inside the mounting groove 19, a slot 22 opened on the outer wall of the sleeve frame 18 for inserting the T-shaped block 20, and a pull rod 21 fixedly installed on the outer wall of the T-shaped block 20. The connecting component 13 also includes a compression spring 23 fixedly installed on the inner wall of the mounting groove 19, and one end of the compression spring 23 is fixedly connected to the inner wall of the mounting groove 19, and the other end of the compression spring 23 is fixedly connected to the outer wall of the T-shaped block 20.
[0050] Specifically, a plurality of threaded holes 16 are provided on one side of the filter plate 3. By tightening or unscrewing the T-shaped studs 17, the number and position of the T-shaped studs 17 on the filter plate 3 can be flexibly changed. By pulling the pull rod 21, the T-shaped block 20 can be driven into the interior of the mounting groove 19, and then the T-shaped block 20 squeezes the compression spring 23, so that the compression spring 23 is compressed to store elastic force. At this time, people can remove the sleeve frame 18 from the T-shaped stud 17. When people need to disassemble and replace one of the filter plates 3, by completely removing the sleeve frame 18 on one of the filter plates 3, one of the filter plates 3 can be made independent, and then one of the filter plates 3 can be taken out upwards for disassembly and replacement.
[0051] Reference Figure 8 The rod wall of the connecting rod 11 is fixedly connected with a guide block 24, and the movable end of the electric push rod 10 is provided with a guide groove 25 for the guide block 24 to slide.
[0052] Specifically, through the cooperation between the guide block 24 and the guide groove 25, it can be ensured that the connecting rod 11 will not deflect and only slide in a straight line direction, thereby further improving the stability of the device in use.
[0053] Example 2, reference Figure 1-Figure 12 ,as well as Fig.14 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the control component 14 includes a first fixed plate 26 fixedly mounted on the rod wall of the connecting rod 11, a first rotating rod 27 rotatably mounted on the outer wall of the cross bar 2, a first cam 28 fixedly mounted at one end of the first rotating rod 27 for pushing the first fixed plate 26, and a first driving motor 29 fixedly mounted on the outer wall of the cross bar 2, and the output shaft of the first driving motor 29 is fixedly connected to the other end of the first rotating rod 27.
[0054] Specifically, the first drive motor 29 can be a servo motor or a stepper motor commonly used in the prior art. By controlling the output shaft of the first drive motor 29 to rotate, the first rotating rod 27 can be driven to rotate. The rotation of the first rotating rod 27 drives the first cam 28 to rotate. The counterclockwise rotation of the first cam 28 can intermittently push the first fixed plate 26 to move toward the direction close to the electric push rod 10.
[0055] The control component 14 also includes a second fixed plate 30 fixedly mounted on the wall of the sealing cylinder 12, a second rotating rod 31 rotatably mounted on the outer wall of the cross bar 2, a second cam 32 fixedly mounted on one end of the second rotating rod 31 for pushing the second fixed plate 30, and a second drive motor 33 fixedly mounted on the outer wall of the cross bar 2, and the output shaft of the second drive motor 33 is fixedly connected to the other end of the second rotating rod 31.
[0056] Specifically, the second drive motor 33 can be a servo motor or a stepper motor commonly used in the prior art. By controlling the output shaft of the second drive motor 33 to rotate, the second rotating rod 31 can be driven to rotate. The rotation of the second rotating rod 31 drives the second cam 32 to rotate. The second cam 32 rotates clockwise and can intermittently push the second fixed plate 30 to move away from the electric push rod 10. The output shafts of the first drive motor 29 and the second drive motor 33 have the same rotation speed and opposite rotation directions.
[0057] Through the cooperation between the second cam 32 and the first cam 28, the multiple filter plates 3 can be synchronously driven to slide left and right. Because under the connection of the connecting component 13, the multiple filter plates 3 are always at the longest distance, and there is friction between the filter plates 3 and the cross bar 2, the inertial sliding of the multiple filter plates 3 is negligible here, which will not affect the normal use of the device.
[0058] Reference Figure 1 The control component 14 also includes a mounting frame 36 fixedly mounted on the top surface of the cross bar 2, a reciprocating screw rod 37 rotatably mounted inside one of the mounting frames 36, a sliding rod 39 fixedly mounted inside the remaining mounting frames 36, and a connecting frame 38 fixedly mounted on the outer wall of the scraper 15, and multiple scrapers 15 are connected by the connecting frame 38, the outer wall of the connecting frame 38 is threadedly connected to the outer wall of the reciprocating screw rod 37, and the outer wall of the connecting frame 38 is slidably connected to the rod wall of the sliding rod 39.
[0059] Specifically, by controlling the rotation of the reciprocating screw rod 37, the connecting frame 38 can be driven to perform reciprocating lifting and lowering. The setting of the slide rod 39 can ensure that the connecting frame 38 performs lifting and lowering movement in the vertical direction without deflection, thereby improving the stability of the scraper 15 when it is lifted and lowered.
[0060] Reference Fig.12The outer wall of the cross bar 2 is rotatably mounted with a third rotating rod 35, and the rod wall of the first rotating rod 27 is connected to the rod wall of the third rotating rod 35 through a gear transmission, and the bottom end of the reciprocating screw rod 37 is connected to the rod wall of the third rotating rod 35 through a bevel gear transmission.
[0061] Specifically, the rod wall of the first rotating rod 27 is sleeved with a first gear, the rod wall of the third rotating rod 35 is sleeved with a second gear, the first gear and the second gear are meshed with each other, wherein the number of teeth of the first gear is multiple times smaller than the number of teeth of the second gear, thereby achieving a deceleration effect of the third rotating rod 35, and the specific deceleration multiple can be determined according to actual usage requirements. The rod wall of the third rotating rod 35 is sleeved with a first bevel gear, and the bottom end of the reciprocating screw rod 37 is sleeved with a second bevel gear, and the first bevel gear and the second bevel gear are meshed with each other.
[0062] Therefore, when the first rotating rod 27 rotates, it can drive the first cam 28 and the reciprocating screw 37 to rotate at the same time, and the rotation speed of the reciprocating screw 37 is less than the rotation speed of the first cam 28, thereby realizing the left and right shaking of multiple filter plates 3 and the lifting and lowering movement of the scraper 15, and the intermittent scraping between the scraper 15 and the filter cloth 6. The number of reciprocating lifting and lowering times of the scraper 15 and the frequency of the left and right shaking of multiple filter plates 3 driven by the first cam 28 and the second cam 32 can be determined according to actual usage requirements, ultimately ensuring that the scraper 15 can fully scrape the surface of the filter cloth 6.
[0063] Reference Fig.14 When the scraper 15 scrapes the surface of the filter cloth 6, in conjunction with the left and right shaking of the filter plate 3, the force exerted by the scraper 15 on the filter cloth 6 can be more impactful and connected, and the particles attached to the surface of the filter cloth 6 can be simultaneously exerted in the up and down and left and right directions, so that the particles attached to the surface of the filter cloth 6 can be more effectively peeled off.
[0064] The remaining structures are the same as those of Example 1.
[0065] Example 3, reference Fig.13 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that the scraper 15 includes a first sharp portion 40, a bend portion 41, and a second sharp portion 42.
[0066] Specifically, when the scraper 15 descends, the first sharp portion 40 is provided, which is conducive to the scraper 15 scraping up the material attached to the surface of the filter cloth 6 from top to bottom, and the inverted portion 41 is provided to apply downward pressure to the scraped material, which is conducive to the scraped material falling downward, and when the scraper 15 rises, the second sharp portion 42 is provided, which is conducive to the scraper 15 scraping up the material attached to the surface of the filter cloth 6 from bottom to top. The rest of the structure is the same as that of Example 2.
[0067] Example 4, reference Figure 1-Figure 14, which is a fourth embodiment of the present invention, provides: an industrial desulfurization wastewater treatment process, comprising the following steps:
[0068] Step 1: By controlling the movable end of the electric push rod 10 to extend, the electric push rod 10 can push the connecting rod 11, and the connecting rod 11 pushes the multiple filter plates 3 in turn until the sealing tube 12 conflicts with the baffle 34, and the filter cloth 6 between the multiple filter plates 3 fits tightly, and the industrial desulfurization wastewater is injected into the grouting pipe 9, and then the solid particles in the industrial desulfurization wastewater are trapped in the two adjacent filter cloths 6, gradually forming a filter cake, and the filtered water can be discharged from the drain pipe 5 through the filter hole 4, and then when the preliminary filtration is completed, the compressed air is injected into the diaphragm 7 through the air hole 8, so that the diaphragm 7 expands to apply additional pressure to the filter cake, further squeezing the moisture in the filter cake.
[0069] Step 2: By controlling the active end of the electric push rod 10 to retract, the multiple filter plates 3 can be pulled apart in sequence. After the filter cake falls from the middle of the multiple filter plates 3, it falls on the material conveying mechanism for transmission. Under the action of the connecting component 13, when the distance between the multiple filter plates 3 is pulled to the maximum distance, the active end of the electric push rod 10 stops retracting.
[0070] Step three: By controlling the output shaft of the first drive motor 29 to rotate, the first rotating rod 27 can be driven to rotate, and the rotation of the first rotating rod 27 drives the first cam 28 to rotate. The counterclockwise rotation of the first cam 28 can intermittently push the first fixed plate 26 to move toward the electric push rod 10. By controlling the output shaft of the second drive motor 33 to rotate, the second rotating rod 31 can be driven to rotate. The rotation of the second rotating rod 31 drives the second cam 32 to rotate. The clockwise rotation of the second cam 32 can intermittently push the second fixed plate 30 to move away from the electric push rod 10. Through the cooperation between the second cam 32 and the first cam 28, multiple filter plates 3 can be synchronously driven to slide left and right.
[0071] Step 4: When the first rotating rod 27 rotates, it can drive the reciprocating screw 37 to rotate at the same time. The rotation of the reciprocating screw 37 can drive the scraper 15 to reciprocate and rise and fall. When the scraper 15 scrapes the surface of the filter cloth 6, it cooperates with the shaking of the filter plate 3 to more effectively peel off the material attached to the surface of the filter cloth 6.
[0072] Step 5: After the surface of the filter cloth 6 is cleaned, the control component 14 controls the plurality of filter plates 3 and the scraper 15 to return to the initial position.
[0073] Step 6: When people need to disassemble and replace one of the filter plates 3, by pulling the pull rod 21, the T-shaped block 20 can be driven into the interior of the installation groove 19, and then the T-shaped block 20 squeezes the compression spring 23, so that the compression spring 23 is compressed to store elastic force. At this time, people can remove the sleeve frame 18 from the T-shaped stud 17. By completely removing the sleeve frame 18 on one of the filter plates 3, one of the filter plates 3 can be made independent, and then one of the filter plates 3 can be taken out upwards, and one of the filter plates 3 can be disassembled and replaced.
