Description

Technical Field

[0001] The present invention relates to the technical field of sludge treatment, and in particular to an underground water tank sludge treatment device and process. Background Art

[0002] Cleaning sludge in the bottom silo of a coal mine is an important maintenance task, which aims to ensure the normal operation of the silo and prevent overflow and blockage caused by sludge accumulation. Effective sludge cleaning helps improve the safety of coal mines and reduce environmental pollution. By converting the bottom sludge in the silo into blocky coal sludge, a plate filter press is required to separate the sludge into solid and liquid. The plate filter press mainly uses a hydraulic system to press the filter plates together tightly to form a sealed chamber. Under pressure, the liquid is discharged through the filter cloth, and the solid particles are trapped and gradually form a filter cake. When the filter cake reaches a certain thickness, it needs to be shut down and the filter plate is loosened so that the filter cake falls by gravity to complete the cleaning. Due to the high organic content or a large amount of hydrophilic substances in the coal-containing sludge, the viscosity of the sludge is increased, making it difficult for the filter cake after filtration to completely fall off the filter cloth. In addition, the sludge in the sewage injection channel in the middle of the filter plate cannot be separated from the filter cloth by gravity due to the support of the filter plate, resulting in substandard sludge cleaning on the filter cloth and shortening the single working time of the filter press.

[0037] The second motor is fixedly connected to the second fixing frame, the output shaft of the second motor is fixedly connected to the third gear, and the third gear is butt-engaged with the rack frame.

[0038] A process for treating underground water tank sludge, using the above-mentioned underground water tank sludge treatment equipment, comprises the following steps:

[0039] Step 1: When the filter cake inside the filter press needs to be cleaned, the two plate pulling trolleys are turned on to dock the plate pulling trolleys with the sliding racks, and the filter plates are driven to slide to an open position through the two sliding racks. At this time, part of the mud plate falls due to gravity, and then the rotating gear is docked with the first gear;

[0040] Step 2: During the process of the rotating gear and the first gear docking, the first fixed frame pushes the trigger rod, so that the trigger rod drives the plug shaft to release the limit between the sliding frame and the filter plate, so that the filter plate can rotate freely;

[0041] Step 3: When the limit between the sliding frame and the filter plate is released and the rotating gear is connected to the first gear, the first motor is turned on, so that the output end of the first motor drives the filter plate to deflect 90° clockwise through the first gear and the rotating gear, and then resets to deflect 90° counterclockwise, so that the impurities on the filter cloth fall due to gravity;

[0042] Step 4: After the filter plate rotates 90°, the third gear is connected to the rack rack, and the second motor is turned on to make the rack rack drop the filter cloth downward through the sliding shaft. Then the output end of the second motor quickly rotates in the opposite direction to quickly reset the filter cloth and tighten it, so that the impurities on it fall off due to the tightening force of the filter cloth.

[0043] Step 5: When the sliding shaft drives the filter cloth to fall, the sliding shaft pulls two adjacent pull ropes, so that the pull ropes drive several fixed blocks thereon to adapt to the falling state of the filter cloth, limit the side of the filter cloth, and disperse the force inside the filter cloth;

[0044] Step 6: After cleaning the filter cloth on one filter plate, repeat the above steps to clean the filter cloth on the remaining filter plates in turn until all the filter cloths are cleaned.

[0045] The present invention has the following advantages: 1. The present invention makes the filter plate in a horizontal state, thereby reducing the support force of the filter cloth on the sludge, and at the same time switches the sewage injection hole on the filter plate from a horizontal state to a vertical state, so that the sludge in the sewage injection hole on the filter plate falls downward due to its own gravity, thereby improving the cleaning effect of the filter cloth on the filter plate.

[0046] 2. The sliding frame and the filter plate are limited by the insertion shaft, so that the filter plate is always in a vertical state while being driven by the plate pulling trolley, avoiding the deviation of the filter plate due to uneven distribution of internal impurities, which affects the subsequent rotation angle of the filter plate.

[0047] 3. By allowing the filter cloth to sag loosely and then quickly rolling up the two ends of the filter cloth, the filter cloth is quickly tightened. In this cycle, the tension of the filter cloth itself is used to separate the impurities attached to it from the filter cloth, further improving the cleaning degree of the filter cloth.

[0048] 4. By cooperating with the pull rope and several fixing blocks, the fixing points on the side of the filter cloth are increased, and the force of the filter cloth to overcome the twisting of the second elastic element is dispersed. At the same time, the fixing blocks limit the side of the filter cloth to avoid curling of the side of the filter cloth when it is restored from a loose state to a tight state.

DETAILED DESCRIPTION

[0060] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the components in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words "connection" in this application include direct and indirect connections unless otherwise specified.

[0061] When treating coal-containing sludge, the sludge contains a high proportion of organic matter and a large amount of hydrophilic components, which leads to its high viscosity and adhesion. This makes it difficult for the filter cake formed during the filtration process to fall off naturally from the filter cloth after the filtration is completed, especially near the sewage injection hole in the middle of the filter plate. The sludge in this area cannot be separated from the filter cloth by gravity because it is supported by the filter plate structure, resulting in incomplete cleaning of the sludge on the surface of the filter cloth. This condition not only reduces the cleaning effect of the filter press, but also forces the equipment to be frequently shut down for manual cleaning, significantly shortening the actual effective working time of the filter press.

[0062] An underground water tank sludge treatment equipment, such as Figure 1-Figure 5 As shown, it includes: a filter press body 1; two plate-pulling trolleys 2, which are slidably connected to the filter press body 1, and the filter press body 1 is provided with two electric slide rails, which are respectively used to drive the adjacent plate-pulling trolleys 2 to move; a plurality of filter units, which are arranged on the filter press body 1 and are used to be spliced ​​with each other to filter the water-containing sludge; a rotating assembly, which is arranged on one of the two plate-pulling trolleys 2, and is used to drive the filter unit to rotate; the filter unit includes: a sliding frame 3, a filter plate 4, a filter cloth 5, Rotating gear 6, contraction assembly and self-locking assembly; two sliding frames 3, slidably connected to the filter press body 1, both sliding frames 3 are rotatably connected to the filter plate 4; filter cloth 5, arranged on the filter plate 4, the filter plate 4 is provided with a sewage injection hole, the filter cloth 5 passes through the sewage injection hole; rotating gear 6, the filter plate 4 is fixedly connected with a transmission shaft, the rotating gear 6 is fixedly connected to the transmission shaft of the filter plate 4; the contraction assembly is arranged on the filter plate 4, for contracting the filter cloth 5; the self-locking assembly is arranged on the filter plate 4, for stabilizing the state of the filter plate 4.

[0063] In the above scheme, the filter press body 1 is composed of a main frame, a thrust plate, a clamping plate, a feeding system and a discharging system. The above components are all prior arts and are common knowledge among personnel in this field, and will not be described in detail here. The plate pulling trolley 2 is prior art and can be docked with two sliding frames 3 and drive them to move synchronously, so as to separate two adjacent filter plates 4 and make the filter cake therebetween fall naturally. A sewage injection channel is provided in the middle of the filter plate 4 for injecting sewage to be filtered. The filter cloth 5 is composed of two rectangular cloths and one cylindrical cloth, and the cylindrical cloth is located in the sewage injection channel of the filter plate 4. The filter cloth 5 is made of nylon and has extremely strong mechanical strength, wear resistance and temperature resistance. By making the filter plate 4 in a horizontal state, the supporting force of the filter cloth 5 on the sludge is weakened, and at the same time, the sewage injection channel on the filter plate 4 is switched from a horizontal state to a vertical state, so that the sludge in the sewage injection channel on the filter plate 4 falls downward under its own gravity, thereby improving the cleaning effect of the filter cloth 5 on the filter plate 4.

[0064] Specifically, Figure 4 and Figure 5As shown, the rotating assembly includes: a first slide rail 201, fixedly connected to the plate pulling trolley 2; a first fixed frame 202, fixedly connected to the slider of the first slide rail 201; a first motor 203, fixedly connected to the first fixed frame 202, and the output shaft of the first motor 203 is fixedly connected to the first gear 204, and the first gear 204 is used to dock and engage with the rotating gear 6.

[0065] In the above scheme, the first slide rail 201 is used to drive the first fixed frame 202 to slide up and down. The first fixed frame 202 is fixedly connected to the telescopic end of the electric push rod or the slider of the electric slide rail. The first motor 203 can be a servo motor or an electric swivel, which is used to rotate the first gear 204. In the initial state, the slider of the first slide rail 201 drives the first fixed frame 202 to be at the bottom, so that the first gear 204 and the rotating gear 6 are misaligned to avoid the first gear 204 directly docking with the rotating gear 6 and getting stuck. The first slide rail 201 and the first motor 203 are both sealed to prevent external water vapor from entering the interior and causing damage to the internal electronic components. The outside of the first gear 204 and the rotating gear 6 are both provided with an anti-rust coating, such as a chrome coating.

[0066] Specifically, Figure 4 and Figure 5 As shown, the self-locking component includes: an insertion shaft 301, which is slidably connected to the sliding frame 3, and the insertion shaft 301 is slidably connected to the transmission shaft of the filter plate 4, and is used to lock the state of the filter plate 4 and the sliding frame 3; a first elastic element 302, which is arranged between the sliding frame 3 and the insertion shaft 301; a trigger rod 303, which is fixedly connected to the insertion shaft 301, and the first fixed frame 202 is used to drive the trigger rod 303 to move synchronously.

[0067] In the above scheme, the plug shaft 301 is made of high-strength steel with high shear strength, which improves the stability of the filter plate 4 and the sliding frame 3. The first elastic element 302 is a tension spring and has been rust-proofed. The first elastic element 302 is used to drive the plug shaft 301 to reset, and the trigger rod 303 is in contact with the first fixed frame 202. In the initial state, the height difference between the first gear 204 and the rotating gear 6 is greater than the depth of the plug shaft 301 entering the transmission shaft of the filter plate 4, which is used to separate the plug shaft 301 from the transmission shaft of the filter plate 4 when the first gear 204 is docked with the rotating gear 6.

[0068] Working principle: The filter press needs to be cleaned of impurities inside regularly to ensure the normal movement of the filter press. When it is necessary to clean the impurities inside the filter press, the filter press is stopped and the squeezing and fixing of several filter plates 4 are released at the same time. Then, the two electric slide rails thereon are opened to make the two plate pulling trolleys 2 move along the filter press body 1 until the two plate pulling trolleys 2 are respectively docked with the adjacent sliding frames 3. Then, the two plate pulling trolleys 2 drive the filter plate 4 to slide along the filter press body 1 through the two sliding frames 3. At this time, the filter plate 4 is separated from the adjacent filter plates 4, and most of the mud plates between the two are not subject to the squeezing force and fall downward due to their own gravity, until the filter plate 4 moves to an empty position (a position convenient for the filter plate 4 to be flipped). Then, the movement of the plate pulling trolley 2 is stopped and the first slide rail 201 is opened at the same time to make the first slide rail 201 The slider drives the first fixed frame 202 to move upward, and at the same time, the first fixed frame 202 squeezes the trigger rod 303, and the trigger rod 303 drives the plugging shaft 301 to slide along the transmission shaft on the sliding frame 3 and the filter plate 4, and at the same time, the first elastic element 302 is stretched, until the plugging shaft 301 is separated from the transmission shaft on the filter plate 4, and the limit of the plugging shaft 301 on the sliding frame 3 and the filter plate 4 is released. At this time, the filter plate 4 can rotate freely along the two sliding frames 3. The sliding frame 3 and the filter plate 4 are limited by the plugging shaft 301, so that the filter plate 4 is always in a vertical state to avoid tilting due to center offset caused by internal impurities, which affects the subsequent rotation angle of the filter plate 4. At the same time, the first fixed frame 202 drives the first gear 204 on its output shaft to complete docking with the rotating gear 6 through the first motor 203, and then closes the first slide rail 201 and turns on the first motor 203.

[0069] When the first gear 204 is connected with the rotating gear 6, the first motor 203 is turned on, so that the output shaft of the first motor 203 drives the rotating gear 6 to rotate 90° clockwise through the first gear 204, so that the rotating gear 6 drives the filter plate 4 to rotate 90° synchronously, and then the first motor 203 is turned off. At this time, the filter plate 4 drives the rectangular cloth of the filter cloth 5 to switch to a horizontal state, and are respectively located on the upper and lower sides of the filter plate 4, so as to weaken the supporting force of the rectangular cloth under the filter plate 4 on the sludge, and at the same time, the sludge in the sewage injection channel on the filter plate 4 is not supported by the filter plate 4. The sludge on the filter plate 4 falls downward under its own gravity, and then the first motor 203 is turned on, so that the output shaft of the first motor 203 drives the filter plate 4 to rotate 180° counterclockwise through the first gear 204 and the rotating gear 6, so that the upper rectangular cloth is switched to the bottom of the filter plate 4, and the gravity force of the sludge on the rectangular cloth is enhanced, so that it falls downward under gravity. By making the filter plate 4 alternately in a horizontal state, the gravity force of the sludge on the filter cloth 5 is enhanced, and at the same time, the sludge located in the sewage injection hole on the filter plate 4 falls downward under its own gravity, thereby improving the cleaning effect of the filter cloth 5 on the filter plate 4.

[0070] When the filter cloth 5 on the filter plate 4 is cleaned, the first motor 203 is turned on, so that the output shaft of the first motor 203 drives the filter plate 4 to rotate 90° clockwise through the rotating gear 6 and the first gear 204 and reset to the initial state, and then the first motor 203 is turned off, and the first slide rail 201 is turned on, so that the slider of the first slide rail 201 drives the first fixed frame 202 to reset downward to the initial state, so that the rotating gear 6 and the first gear 204 are separated, and at the same time, the first elastic element 302 drives the trigger rod 303 to move downward synchronously, so that the trigger rod 303 drives the insertion shaft 301 to slide into the rotating shaft of the sliding frame 3, so that the sliding frame 3 limits the filter plate 4, and then the two pulling plate trolleys 2 are controlled to separate from the sliding frame 3, and dock with the sliding frame 3 of the next filter plate 4, and the above steps are repeated until the filter cloth 5 on all filter plates 4 are cleaned, that is, the cleaning of the filter press body 1 is completed.

[0071] In this embodiment, the connection relationship between the filter cloth 5 and the filter plate 4 is a fixed connection, but it is limited to this embodiment. In other subsequent embodiments, the filter cloth 5 is arranged on the filter plate 4. Please refer to the specific description in the subsequent embodiments.

[0072] In a further embodiment, Figure 6-Figure 10 As shown, it also includes: four rotating shafts 401, all of which are rotatably connected to the filter plate 4, the filter cloth 5 is fixedly connected between the four rotating shafts 401, the filter cloth 5 is wound around the outside of the four rotating shafts 401, a second elastic element 402 is arranged between the rotating shaft 401 and the filter plate 4, four sliding shafts 403 are fixedly connected to the middle of the filter cloth 5, the filter plate 4 is fixedly connected to a connecting frame, and the sliding shaft 403 is slidably connected to the connecting frame on the filter plate 4; there are two trigger components, which are respectively arranged on both sides of the filter plate 4, and are used to drive the sliding shaft 403 to slide along the filter plate 4.

[0073] In the above scheme, the two rotating shafts 401 on the upper and lower sides of the filter plate 4 are respectively divided into a group, and the upper and lower sides of the two rectangular cloths of the filter cloth 5 are respectively wound around the two adjacent rotating shafts 401, and the second elastic element 402 is a torsion spring and has been rust-proofed, which is used to drive the adjacent rotating shafts 401 to reset, and the sliding shaft 403 is fixedly connected to the middle part of the rectangular cloth of the filter cloth 5, so that the filter cloth 5 can hang down and become loose. The filter cloth 5 and the sliding shaft 403 are both detachably fixedly connected, which is convenient for the replacement of the filter cloth 5.

[0074] Specifically, Figure 8-Figure 10As shown, the trigger assembly includes: a rack frame 404, a filter plate 4 is fixedly connected to a connecting frame, and the rack frame 404 is slidably connected to the connecting frame of the filter plate 4; a push plate 405, fixedly connected to the rack frame 404, and the push plate 405 is in contact with two adjacent sliding shafts 403; a third elastic element 406, which has two parts and is arranged between the sliding shaft 403 and the connecting frame of the filter plate 4; a pull rope 407 is fixedly connected between the sliding shaft 403 and two adjacent rotating shafts 401, and the pull rope 407 is wound around the outside of the rotating shaft 401, and a plurality of fixed blocks 408 are fixedly connected between the pull rope 407 and the filter cloth 5; the fixed blocks 408 on both sides of the filter plate 4 are staggered and distributed, so as to evenly disperse the internal force of the filter cloth 5; the winding directions of the filter cloth 5 on the rotating shafts 401 on both sides are opposite, and the winding directions of the pull rope 407 and the filter cloth 5 on the same rotating shaft 401 are the same, so as to make the pull rope 407 adapt to the shape change of the filter cloth 5.

[0075] In the above scheme, the rack frame 404 is provided with an anti-rust coating, such as a chrome coating, and the third elastic element 406 is a spring and has been treated with anti-rust, and is used to drive the sliding shaft 403 to reset. The pull rope 407 is made of metal and has a certain structural strength. The pull rope 407 is initially in a vertical state, so that the sliding shaft 403 can directly pull the rotating shaft 401 to rotate through the pull rope 407. Figure 6 The fixing blocks 408 on the front and rear sides of the filter plate 4 are staggered and used to fix the filter cloth 5 by staggering the fixing blocks 408, so as to further disperse the force in the filter cloth 5. Meanwhile, the fixing blocks 408 and the filter cloth 5 are both detachably fixedly connected, so as to facilitate the removal and replacement of the filter cloth 5. The upper and lower sides of the rectangular cloth of the filter cloth 5 are respectively opposite to the winding directions on the two adjacent rotating shafts 401, so as to facilitate the loose hanging of the filter cloth 5. The filter cloth 5 on the rotating shaft 401 and the pull rope 407 have the same winding directions, so as to adapt to the position change of the side of the filter cloth 5.

[0076] Specifically, Fig. 9 and Fig.10 As shown, it also includes: a driving component, having two, respectively arranged on the two plate pulling trolleys 2, for driving the rack 404 to move, the driving component includes: a second slide rail 501, fixedly connected to the plate pulling trolley 2; a second fixed frame 502, fixedly connected to the slider of the second slide rail 501; a second motor 503, fixedly connected to the second fixed frame 502, the output shaft of the second motor 503 is fixedly connected to the third gear 504, and the third gear 504 is connected and meshed with the rack 404.

[0077] In the above scheme, the second slide rail 501 and the second motor 503 are both sealed to prevent external moisture from entering the interior and causing damage. The second slide rail 501 is used to drive the second fixed frame 502 to slide left and right. The outside of the third gear 504 is provided with an anti-rust coating, such as a chrome coating. In the initial state, there is a height difference between the rack frame 404 and the third gear 504, which facilitates the docking of the rack frame 404 and the third gear 504.

[0078] Working principle: when the filter plate 4 is in a horizontal state, the two second slide rails 501 are opened, and the slider of the second slide rail 501 drives the second fixing frame 502 to move horizontally, so that the second fixing frame 502 drives the third gear 504 on the output shaft of the second motor 503 to dock with the rack frame 404, and then the second motor 503 is turned on, so that the output shaft of the second motor 503 drives the third gear 504 to rotate, and the third gear 504 drives the rack frame 404 to slide downward along the connecting frame on the filter plate 4, at this time, the third elastic element 406 located below is compressed, and the rack frame 404 drives the push plate 405 to move downward synchronously, and the push plate 405 pushes the sliding shaft 403 below to move downward synchronously, and the two sliding shafts 403 below drive the middle part of the rectangular filter cloth 5 to move downward synchronously, and the rectangular filter cloth 5 The middle part of the filter cloth 5 moves downward to pull its two ends, and the filter cloth 5 pulls the rotating shafts 401 on both sides to rotate along the filter plate 4, and the two second elastic elements 402 are twisted at the same time, until the two second elastic elements 402 are twisted to the limit state, at which time the output shaft of the second motor 503 quickly rotates in the opposite direction to reset to the initial state, and the two second elastic elements 402 immediately rewind the two ends of the filter cloth 5, and at the same time the third elastic element 406 drives the middle part of the filter cloth 5 to reset through the sliding shaft 403, and so on. By making the filter cloth 5 loosely droop, and then quickly rewinding the two ends of the filter cloth 5, the filter cloth 5 is quickly tightened, and so on. The tightening force of the filter cloth 5 itself separates the impurities attached to it from the filter cloth 5, and the cleaning degree of the filter cloth 5 is further improved.

[0079] After the filter cloth 5 is cleaned, the second slide rail 501 is opened, and the slider of the second slide rail 501 drives the third gear 504 to reset to the initial state through the second fixed frame 502, and then the second slide rail 501 is closed, and then the output shaft of the first motor 203 drives the filter plate 4 to rotate 180° in the opposite direction, and the first motor 203 is turned off and the second slide rail 501 is opened, so that the slider of the second slide rail 501 moves in the opposite direction horizontally, so that the third gear 504 is meshed with the rack frame 404 again, and the above steps are repeated again to shrink and tighten another rectangular cloth. After cleaning, the second slide rail 501 is opened, and the slider of the second slide rail 501 drives the third gear 504 to reset to the initial state, and the cycle is repeated until the filter cloth 5 on all filter plates 4 is cleaned.

[0080] When the sliding shaft 403 drives the middle part of the rectangular cloth of the filter cloth 5 to droop downward, the sliding shaft 403 pulls the two adjacent pull ropes 407, so that the pull ropes 407 pull the adjacent rotating shaft 401, so that the rotating shaft 401 rotates along the filter plate 4 under the joint action of the rectangular cloth of the filter cloth 5 and the pull ropes 407, reducing the force of the rectangular cloth of the filter cloth 5 to overcome the torsion of the second elastic element 402, and at the same time, the pull ropes 407 drive the fixed blocks 408 of the linear array thereon to move synchronously, and the pull ropes 407 change synchronously with the side of the filter cloth 5 and present an inclined state, so that the pull ropes 407 adapt to the loose shape of the rectangular cloth of the filter cloth 5, and at the same time, several fixed blocks 408 fix the side of the rectangular cloth of the filter cloth 5 at multiple points, further disperse the internal force of the rectangular cloth of the filter cloth 5, and extend the service life of the filter cloth 5. At the same time, several fixed blocks 408 limit the side of the filter cloth 5 to prevent the side of the filter cloth 5 from curling when it is restored to a tight state from a loose state.

[0081] In a further embodiment, Figure 1-Figure 10 As shown, a process for treating sludge in underground water tanks, using the above-mentioned equipment for treating sludge in underground water tanks, comprises the following steps:

[0082] Step 1: When the filter cake inside the filter press needs to be cleaned, the two plate-pulling trolleys 2 are opened to dock the plate-pulling trolleys 2 with the sliding racks 3, and the filter plates 4 are driven to slide to an empty position through the two sliding racks 3. At this time, part of the mud plate falls due to gravity, and then the rotating gear 6 is docked with the first gear 204;

[0083] Step 2: During the docking process between the rotating gear 6 and the first gear 204, the first fixing frame 202 pushes the trigger rod 303, so that the trigger rod 303 drives the plugging shaft 301 to release the limit between the sliding frame 3 and the filter plate 4, so that the filter plate 4 can rotate freely;

[0084] Step 3: When the limit between the sliding frame 3 and the filter plate 4 is released and the rotating gear 6 is connected to the first gear 204, the first motor 203 is turned on, so that the output end of the first motor 203 drives the filter plate 4 to deflect 90° clockwise through the first gear 204 and the rotating gear 6, and then resets to deflect 90° counterclockwise, so that the impurities on the filter cloth 5 fall due to gravity;

[0085] Step 4: After the filter plate 4 rotates 90°, the third gear 504 is docked with the rack frame 404, and the second motor 503 is turned on, so that the rack frame 404 causes the filter cloth 5 to drop downward through the sliding shaft 403, and then the output end of the second motor 503 quickly rotates in the opposite direction, so that the filter cloth 5 is quickly reset and tightened, so that the impurities on the filter cloth 5 fall due to the tightening force of the filter cloth 5;

[0086] Step 5: When the sliding shaft 403 drives the filter cloth 5 to fall, the sliding shaft 403 pulls two adjacent pull ropes 407, so that the pull ropes 407 drive the fixed blocks 408 thereon to adapt to the falling state of the filter cloth 5, limit the side of the filter cloth 5, and disperse the force inside the filter cloth 5;

[0087] Step 6: After the filter cloth 5 on one filter plate 4 is cleaned, the above steps are repeated to clean the filter cloths 5 on the remaining filter plates 4 in turn, until all the filter cloths 5 are cleaned.

[0088] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
