Description

Technical Field

[0001] This invention relates to a cleaning device, and more particularly to a vertical plate filter cloth cleaning device. Background Technology

[0002] In processes such as solid-liquid separation, wastewater treatment, and chemical production, filter cloth, as a core component of filtration equipment, directly affects filtration efficiency and the quality of the final product. Over long-term use, filter cloth easily absorbs particulate impurities, colloidal substances, and other difficult-to-remove residues. Failure to clean it promptly and effectively can not only reduce filtration efficiency but also lead to deterioration of effluent quality or a decrease in product purity. In severe cases, it can even cause equipment blockage or malfunctions, affecting the continuity and stability of production. Therefore, regular cleaning of filter cloth is necessary.

[0003] Currently, filter cloth cleaning systems typically employ vertical plate-type filter cloth cleaning systems. These systems usually rely on multiple cleaning units mounted on a mobile truss. These units share a single suction pump to periodically perform synchronized pumping backwashing operations on multiple rows of filter cloth. This method aims to remove impurities trapped on the filter cloth surface during filtration through the negative pressure generated by the pump, preventing filter cloth clogging. However, in actual cleaning operations, due to the high adhesiveness of contaminants, the suction provided by the pump alone is often insufficient to thoroughly clean the impurities on the filter cloth, resulting in poor cleaning performance. Summary of the Invention

[0004] In view of this, the present invention provides a vertical plate filter cloth cleaning device.

[0005] The technical solution of the present invention is as follows: a vertical plate filter cloth cleaning device, comprising a pool body, guide rails, filter cloth frame, sludge discharge trough, water outlet pipe, sludge discharge pipe, suction mechanism, and striking mechanism. Multiple sets of guide rails are installed on both sides of the top of the pool body, with two guide rails in each set. The guide rails are detachable. A filter cloth frame is installed at the bottom of the guide rail, and filter cloth can be installed on both sides of the filter cloth frame. Several sludge discharge troughs are connected to both sides of the top of the pool body, the number of sludge discharge troughs being the same as the number of guide rail sets. Multiple sludge discharge troughs are located between two guide rails in multiple sets. A water outlet pipe is connected to the pool body, and a sludge discharge pipe is connected between two sludge discharge troughs. Valves are installed at both the sludge discharge pipe and the water outlet pipe. A suction mechanism for absorbing impurities is provided on the guide rails, and a striking mechanism for striking the filter cloth is provided between the guide rails and the filter cloth frame.

[0006] As a further preferred embodiment, the suction mechanism includes a suction frame, a connecting plate, an electric roller, and rollers. Suction frames are provided on both sides of the guide rail, and connecting plates are connected to the top two sides of the suction frames. An electric roller is installed in the middle of the connecting plate, and rollers are connected to the electric rollers. The rollers press against the rails of the guide rail.

[0007] As a further preferred embodiment, the sludge suction mechanism also includes a water pump, a water suction pipe, and a sewage discharge pipe. A water pump is installed between the tops of the suction frames on both sides of the same guide rail. The water pump's suction end is connected to two water suction pipes, which are respectively connected to two suction frames that are close to it. The water pump's outlet end is connected to a sewage discharge pipe, and the sewage discharge end is aligned with the top of the sludge discharge trough.

[0008] As a further preferred embodiment, the striking mechanism includes a mounting plate, a drive motor, a sliding frame, a pressing cam, a striking frame, and elastic elements. The mounting plate is rotatably connected to four electric rollers on the same guide rail. The drive motor is mounted on the top center of the mounting plate. The sliding frame is slidably connected inside the filter cloth frame. The output shaft of the drive motor passes through the sliding frame and is connected to the pressing cam. The top of the sliding frame is connected to the bottom of the mounting plate. Striking frames are slidably connected to both sides of the sliding frame. The striking frames can move to strike the filter cloth. Two elastic elements are connected between the striking frames and the sliding frame.

[0009] As a further preferred embodiment, a cleaning mechanism is also included, which comprises a large bevel gear, a cleaning roller brush, and a small bevel gear. The large bevel gear is connected to the electric roller shaft, and the cleaning roller brushes are rotatably connected to both sides of the suction frame. The small bevel gear is connected to the top of the cleaning roller brush, and the small bevel gear meshes with the large bevel gear adjacent to it.

[0010] As a further preferred embodiment, a rinsing mechanism is also included, comprising an inner tube, an outer tube, and a piston block. Multiple inner tubes are evenly spaced along the inner side of the striking frame, and multiple outer tubes are evenly spaced along both sides of the sliding frame. The number of outer tubes and inner tubes is the same. The inner tubes pass through the sliding frame and are located inside the outer tubes. A piston block is connected to the end of each inner tube, and the piston block slides and seals against the outer tube. Multiple communicating holes are evenly spaced along the portion of the inner tube located within the outer tube. A spray groove is provided on the striking frame, and the inner tubes communicate with the spray groove.

[0011] As a further preferred embodiment, a folding sealing gasket is also included, with the top center of the guide rail connected to the folding sealing gasket.

[0012] As a further preferred option, each row of filter cloth is equipped with a cleaning mechanism that can perform individual cleaning of each row of filter cloth.

[0013] The present invention has the following advantages: 1. In the process of cleaning the filter cloth, the present invention can use a tapping frame to tap the filter cloth, causing the filter cloth to vibrate and help shake off the impurities attached to the filter cloth. At the same time, the suction frame generates suction to adsorb the impurities, thereby cleaning the filter cloth and achieving a better cleaning effect.

[0014] 2. During the cleaning process, the present invention can also control the rotation of the cleaning roller to assist in brushing the filter cloth. At the same time, water can be added into the outer cylinder by moving the tapping frame, and then the water is sprayed onto the filter cloth through the spray tank to improve the cleaning effect of the filter cloth, thus achieving a better cleaning effect.

Detailed Implementation

[0026] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0027] A vertical plate filter cloth cleaning device, such as Figures 1-3 As shown, the system includes a pool body 1, guide rails 2, filter cloth frame 3, sludge discharge trough 4, water outlet pipe 5, sludge discharge pipe 6, a suction mechanism, and a striking mechanism. Two guide rails 2 are installed on the top left and right sides of the pool body 1. The guide rails 2 are detachable. A filter cloth frame 3 is installed at the bottom of the guide rails 2, and filter cloths 100 can be installed on both sides of the filter cloth frame 3 for cleaning. Sludge discharge troughs 4 are connected to the top left and right sides of the pool body 1, located between the two guide rails 2 on each side. A water outlet pipe 5 is connected to the lower front of the pool body 1, and a sludge discharge pipe 6 is connected between the front sides of the two sludge discharge troughs 4. Valves are installed at both the sludge discharge pipe 6 and the water outlet pipe 5. A suction mechanism for absorbing impurities is provided on the guide rails 2, and a striking mechanism for striking the filter cloth 100 is provided between the guide rails 2 and the filter cloth frame 3.

[0028] like Figures 1-3 As shown, the suction mechanism includes a suction frame 71, a connecting plate 72, an electric roller 73, rollers 74, a water pump 75, a water suction pipe 76, and a sewage discharge pipe 77. Suction frames 71 are provided on both the left and right sides of the guide rail 2. Connecting plates 72 are connected to the top front and rear sides of each suction frame 71. An electric roller 73 is installed in the middle of the connecting plate 72, and rollers 74 are connected to the electric roller 73. The rollers 74 press against the rails of the guide rail 2, so that when the electric roller 73 drives the rollers 74 to rotate... The roller 74 can move along the guide rail 2. When the roller 74 moves, it can drive the suction frame 71 to move through the electric roller 73 and the connecting plate 72. A water pump 75 is installed between the tops of the suction frames 71 on both sides of the same guide rail 2. The water pump 75 is connected to two water pump pipes 76 at the water pump end. The two water pump pipes 76 are respectively connected to the two suction frames 71 that are close to them. The water pump 75 is connected to a sewage pipe 77 at the water outlet end. The sewage pipe 77 is aligned with the top of the sludge discharge trough 4.

[0029] like Figures 1-3 As shown, the striking mechanism includes a mounting plate 81, a drive motor 82, a sliding frame 83, a pressing cam 84, a striking frame 85, and elastic elements 86. The mounting plate 81 is rotatably connected to four electric rollers 73 on the same guide rail 2. The drive motor 82 is mounted in the middle of the top of the mounting plate 81. The sliding frame 83 is slidably connected inside the filter cloth frame 3. The sliding frame 83 slides back and forth with the filter cloth frame 3 and the mounting plate 81 respectively. The output shaft of the drive motor 82 passes through the sliding frame 83 and is connected to the pressing cam 84. The top of the sliding frame 83 is connected to the bottom of the mounting plate 81. The striking frames 85 are slidably connected to both sides of the sliding frame 83. The striking frames 85 can move to strike the filter cloth 100. Two elastic elements 86, which are connecting springs, are connected between the striking frames 85 and the sliding frame 83.

[0030] When the filter cloth 100 needs to be cleaned, this cleaning device can be used. During cleaning, first remove the guide rail 2 and filter cloth frame 3. Then, hang the filter cloth 100 to be cleaned on both sides of the filter cloth frame 3. The hung filter cloth 100 is located inside the suction frame 71. After the operation is complete, put the guide rail 2 and filter cloth 100 back into the tank 1. Once placed, the cleaning work can begin. During cleaning, the water pump 75 is operated to create negative pressure inside the suction frame 71 through the water pipe 76, thereby removing the filter cloth. Dust and impurities adhering to the filter cloth 100 are sucked into the suction frame 71. During the extraction process, because the pool 1 contains water, the suction frame 71 generates negative pressure, drawing water into the suction frame 71. This water flows through the filter cloth 100, assisting in rinsing the filter cloth 100. Impurities in the suction frame 71 are then pumped into the water pump 75 through the suction pipe 76, and finally discharged into the sludge discharge tank 4 through the sewage discharge pipe 77. The sludge discharge tank 4 collects impurities and wastewater. During the cleaning process, [the following text is incomplete and likely refers to a separate process:] The electric roller 73 drives the roller 74 to rotate, thereby moving the suction frame 71 back and forth along the guide rail 2 to suction impurities at different positions on the filter cloth 100. During the suction process, the drive motor 82 can also be controlled to operate. When the drive motor 82 operates, it can drive the extrusion cam 84 to rotate. When the extrusion cam 84 rotates, it can contact the two sides of the striking frame 85 in turn, thereby repeatedly squeezing the two sides of the striking frame 85, causing the striking frame 85 to strike the filter cloth 100. The elastic element 86 is compressed. When the extrusion cam 84 separates from the striking frame 85 when it rotates, the striking frame 85 is squeezed back to its original position under the action of the elastic element 86. This is repeated to continuously strike the filter cloth 100, causing the filter cloth 100 to vibrate and help shake off the impurities attached to the filter cloth 100. In this way, the filter cloth 100 can be cleaned. In addition, the filter cloth 100 can be continuously shaken during the cleaning process to help shake off the impurities attached to the filter cloth 100, thereby achieving the cleaning of the filter cloth 100.

[0031] like Figure 4 and Figure 5 As shown, it also includes a cleaning mechanism. Each row of filter cloths is equipped with a cleaning mechanism that can perform single-group cleaning of each row of filter cloths. The cleaning mechanism includes a large bevel gear 91, a cleaning roller brush 92, and a small bevel gear 93. The large bevel gear 91 is connected to the electric roller 73. The cleaning roller brush 92 is rotatably connected to both the front and rear sides of the suction frame 71. The small bevel gear 93 is connected to the top of the cleaning roller brush 92. The small bevel gear 93 meshes with the large bevel gear 91, so that when the electric roller 73 rotates, it can drive the cleaning roller brush 92 to rotate through the large bevel gear 91 and the small bevel gear 93.

[0032] When the electric roller 73 rotates, it can drive the large bevel gear 91 to rotate. When the large bevel gear 91 rotates, it can drive the small bevel gear 93 to rotate. When the small bevel gear 93 rotates, it can drive the cleaning roller brush 92 to rotate. When the cleaning roller brush 92 rotates, it can brush and wash the impurities on the filter cloth 100, assisting in cleaning the filter cloth 100 and improving the cleaning effect.

[0033] like Figures 6-8 As shown, it also includes a rinsing mechanism, which includes an inner tube 101, an outer tube 102, and a piston block 103. Multiple inner tubes 101 are evenly spaced on the inner side of the striking frame 85. Multiple outer tubes 102 are evenly spaced on both the left and right sides of the sliding frame 83. The number of outer tubes 102 and inner tubes 101 is the same. The inner tubes 101 pass through the sliding frame 83 and are located inside the outer tubes 102. The piston block 103 is connected to the end of the inner tube 101. The piston block 103 slides and seals with the outer tube 102. Multiple communicating holes are evenly spaced on the part of the inner tube 101 located in the outer tube 102. A spray groove 851 is provided on the striking frame 85. The inner tube 101 is connected to the spray groove 851. The water flow sprayed from the spray groove 851 can spray onto the inner wall of the filter cloth 100, thereby assisting in rinsing the filter cloth 100 and achieving the effect of assisting in cleaning the filter cloth 100.

[0034] When the striking frame 85 moves, it can drive the inner tube 101 to move together. When the inner tube 101 moves, it can drive the piston block 103 to move together. When the piston block 103 moves into the sliding frame 83, it can generate negative pressure in the outer tube 102, thereby drawing water from the pool 1 into the inner tube 101 and the outer tube 102 through the connecting hole and the spray tank. When the piston block 103 moves out of the sliding frame 83, it can inject water from the outer tube 102 into the inner tube 101 through the connecting hole, and finally spray it out through the spray tank, thereby spraying water onto the filter cloth 100, assisting in rinsing the filter cloth 100 and improving the cleaning effect of the filter cloth 100.

[0035] like Figure 9 and Figure 10 As shown, it also includes a folded sealing gasket 12. The top center of the guide rail 2 is connected to the folded sealing gasket 12. The sliding frame 83 passes through the folded sealing gasket 12. The folded sealing gasket 12 can block the gap in the middle of the guide rail 2 to prevent impurities from entering the filter cloth frame 3 through the gap in the middle of the guide rail 2. When the sliding frame 83 moves, it can drive the folded sealing gasket 12 to adjust the folded position. The foldable setting of the folded sealing gasket 12 ensures the sealing effect of the guide rail 2.

[0036] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
