Description

Technical Field

[0001] This utility model relates to the field of filter plate cleaning for filter presses, and in particular to a filter plate cleaning device for filter presses. Background Technology

[0002] As a core piece of equipment in the field of solid-liquid separation, filter presses are widely used in various industries such as chemical, mining, wastewater treatment, and food processing. Their filtration efficiency is directly related to the cleanliness of the filter plates. During long-term use, filter cloth pores and the surface of the filter plates easily accumulate filter residue, sticky impurities, and other contaminants. If not cleaned thoroughly and promptly, this can lead to blockage of the filtration channels and increased filtration resistance. This not only reduces the filter press's processing efficiency but also causes deformation and damage to the filter plates due to uneven stress, significantly shortening their lifespan. Furthermore, it affects the purity of subsequent filtered products and can even lead to product defects. Therefore, efficient and thorough cleaning of the filter plates has become a crucial factor in ensuring the stable operation of the filter press.

[0003] Existing cleaning devices mostly use high-pressure rinsing or fixed brushing. The residual moisture on the surface of the filter plate and the gaps in the filter cloth after cleaning becomes a new hidden danger. Micron-sized mud particles that are not completely removed will dissolve in the residual moisture. As the moisture evaporates during the natural drying process, these mud particles will solidify in the pores of the filter cloth and on the surface of the filter plate, forming secondary hardening. Because this type of hardening is more tightly bonded to the surface of the filter material, higher pressure or longer treatment is required in the next cleaning, which directly leads to a decrease in the air permeability of the filter cloth in subsequent filtration stages. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a filter plate cleaning device for a filter press, which aims to improve the problem in the prior art where mud particles on the surface of the cleaned filter plate and in the gaps of the filter cloth form secondary hardening after the residual moisture dries.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A filter plate cleaning device for a filter press, specifically, includes a filter press frame, a filter plate translation device installed on the filter press frame, a gantry cleaning frame slidably connected to the filter press frame, a lifting device installed on the inner wall of the gantry cleaning frame, and a lifting mounting plate at the bottom end of the lifting device; The bottom of the lifting mounting plate is provided with two flip plates. The inner side wall of the flip plate is fixedly connected with water-absorbing cotton. The outer side wall of the flip plate has several bristles. A flipping mechanism is provided between the flip plate and the lifting mounting plate. A spray washing mechanism is provided at the bottom of the lifting mounting plate.

[0006] As a further description of the above technical solution, the two flip plates are placed on both sides below the lifting mounting plate, and the distance between them is adapted to the filter plate. The two flip plates are symmetrically distributed.

[0007] As a further description of the above technical solution, the flipping mechanism includes two connecting frames, which are fixed to both sides of the lifting mounting plate, and one side wall of the flipping plate is rotatably connected to the connecting frame on the same side.

[0008] As a further description of the above technical solution, a drive unit is installed at one end of another of the connecting frames, and the output shaft of the drive unit is connected to the other side wall of the flip plate in a transmission connection.

[0009] As a further description of the above technical solution, the drive unit is specifically a waterproof motor.

[0010] As a further description of the above technical solution, the spraying mechanism includes fixed plates fixed to both sides of the bottom end of the lifting mounting plate, and spray pipes are fixedly connected to both sides between the two fixed plates. Several nozzles are obliquely installed on the outer side of the spray pipes.

[0011] As a further description of the above technical solution, a conveying pipe is installed in the middle between the two fixed plates. The conveying pipe is connected to the inner cavity of the two nozzles through a pipe, and one end of the conveying pipe is connected to an external water supply device.

[0012] This utility model has the following beneficial effects: In this invention, by setting up a rotating plate with brush bristles and absorbent cotton, and coordinating it with a spraying mechanism and a lifting device, efficient phased cleaning of the filter plate can be achieved. First, the brush bristles on the outside of the rotating plate are used to brush the surface of the filter plate from top to bottom under the drive of the lifting device, effectively softening the hardened dirt and laying the foundation for subsequent cleaning. Then, the spraying nozzles of the spraying mechanism immediately rinse the brushed area, improving the dirt removal effect. After rinsing, the rotating mechanism drives the rotating plate to rotate, so that the absorbent cotton on the inside contacts the filter plate. Then, the lifting device drives it to move from bottom to top to wipe away residual moisture on the surface of the filter plate and the gaps in the filter cloth, avoiding secondary hardening due to residual moisture, ensuring the air permeability of the filter cloth and the subsequent use effect of the filter plate, and improving the cleaning efficiency and effect.

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] Please see Figures 1 to 4 A preferred embodiment of this utility model provides a filter plate cleaning device for a filter press, which mainly includes a filter press frame 1, a filter plate translation device 2, and a gantry cleaning frame 3.

[0020] The filter press frame 1 serves as the basic support component of the entire cleaning device, undertaking the installation and load-bearing functions of core components such as the filter plate translation device 2 and the gantry cleaning frame 3.

[0021] The filter plate translation device 2 is located on both sides of the upper end face of the frame of the filter press frame 1. It is used for the automated conveying and positioning of the filter plates to be cleaned. It can accurately move the filter plates to the cleaning area of ​​the gantry cleaning frame 3 and fix them directly below the gantry cleaning frame 3. After one side of the filter plate is cleaned, it is moved by the filter plate translation device 2 to the rear of the gantry cleaning frame 3 and stacked. The above steps are repeated to clean both sides of the filter plate. Specifically, the filter plate translation device 2 is a filter plate moving trolley in the prior art. The moving trolley is equipped with a buckle structure. The buckle structure fixes a single filter plate on the moving trolley. As the moving trolley moves, the filter plate on it is separated from the adjacent filter plates, thereby providing space for cleaning the filter plate surface.

[0022] The gantry cleaning frame 3 is located on both sides of the upper end of the frame of the filter press frame 1. A lifting device 4 is installed on the inner wall of the gantry cleaning frame 3, providing vertical power. Specifically, the lifting device 4 is a scissor lift, which is a lifting platform formed by connecting rods with a scissor-like structure. Multiple sets of connecting rods are cross-hinged and stacked in an "X" shape. Lifting is achieved by changing the included angle of the "X". The bottom end of the lifting device 4 is provided with a lifting mounting plate 5, which is driven to move vertically by the lifting device 4. The length of the lifting mounting plate 5 is adapted to the width of the filter plate. Two flip plates 6 are provided at the bottom of the lifting mounting plate 5. The two flip plates 6 are placed on both sides below the lifting mounting plate 5, and the distance between them is adapted to the filter plate. The two flip plates 6 are symmetrically distributed and can closely fit the corresponding sides of two adjacent filter plates. The outer side wall of the flip plate 6 is provided with bristles 61. During the cleaning stage, the lifting mounting plate 5 can be driven to move the flip plates 6 from top to bottom, so that the bristles 61 on the outer side of the flip plates 6 can fully brush the surface of the filter plate and soften the hardened soil.

[0023] The bristles 61 on the outer wall of the flip plate 6 are used to directly contact the filter plate surface. Driven by the lifting device 4, they brush from top to bottom, physically softening the hardened soil. The inner wall of the flip plate 6 is fixedly connected with absorbent cotton 7, which can tightly cover the filter plate surface and filter cloth gaps. Through the movement from bottom to top or bottom to top, residual moisture is wiped away. A flipping mechanism 8 is provided between the flip plate 6 and the lifting mounting plate 5. A spray washing mechanism 9 is provided at the bottom of the lifting mounting plate 5. The spray washing mechanism 9 includes fixed plates 91 fixed to both sides of the bottom end of the lifting mounting plate 5. Spray pipes 92 are fixedly connected to both sides between the two fixed plates 91. Several spray pipes are obliquely installed on the outer side of the spray pipes 92. A nozzle 94 is installed with its tilt angle at 45 degrees to the surface of the filter plate, which can achieve precise coverage of the brushing area by the water flow. A conveying pipe 93 is installed in the middle between the two fixed plates 91. Multiple nozzles 94 are distributed along the axial direction of the conveying pipe 93. The water spray direction of the nozzles 94 is outward and tilted downward. The conveying pipe 93 is connected to the inner cavity of the two spray pipes 92 through the pipe. One end of the conveying pipe 93 is connected to an external water supply device. The external water supply device can provide high-pressure water flow, which is distributed to the spray pipes 92 through the conveying pipe 93 and then sprayed out by the nozzles 94 to rinse the surface of the brushed filter plate in time, effectively removing the softened mud. The flipping mechanism 8 includes two connecting frames 81, which are fixed to both sides of the lifting mounting plate 5. One side wall of the flipping plate 6 is rotatably connected to the connecting frame 81 on the same side. A drive unit 82 is installed at one end of the other connecting frame 81. The output shaft of the drive unit 82 is connected to the other side wall of the flipping plate 6. The drive unit 82 is a waterproof motor. After the brushing and spraying processes are completed, the waterproof motor drives the flipping plate 6 to rotate 180° around the connecting frame 81, causing the inner absorbent cotton 7 to flip and contact the filter plate surface. The lifting device 4 drives the lifting mounting plate 5 to move the flipping plate 6 up and down. The absorbent cotton 7 tightly adheres to the filter plate surface and filter cloth gaps, wiping away residual moisture and preventing the mud particles from solidifying and forming secondary pollution after the moisture evaporates. The spraying mechanism 9 has nozzles 94 that are distributed obliquely on the outside of the spray pipe 92. The spraying direction corresponds to the action area of ​​the brush bristles 61 of the flipping plate 6. After the brush bristles 61 have finished brushing the filter plate surface, the area can be immediately rinsed with high-pressure water to improve the removal effect of mud and dirt. The flip plate 6 is rotatably connected to the lifting mounting plate 5 via a connecting frame 81. The bristles 61 on its outer side wall and the absorbent cotton 7 on its inner side wall correspond to different cleaning stages. Under the action of the drive unit 82, it can achieve a 180° flip. When brushing and spraying are performed, the bristles 61 face the filter plate. After completion, it flips so that the absorbent cotton 7 contacts the filter plate. In conjunction with the lifting action of the lifting device 4, the residual moisture on the surface of the filter plate is wiped away. In an exemplary embodiment, preferably, the absorbent cotton 7 first moves upward with the lifting device 4, and then moves downward with the lifting device 4, performing two wiping operations.Considering that the absorbent cotton 7 contains a certain amount of moisture, when wiping upwards, the water in the absorbent cotton 7 is squeezed out and flows downwards along the filter plate. At this time, the absorbent cotton 7 is moved downwards again with the lifting device 4 for another wipe, which can achieve a cleaner wipe. It is understandable that when using the absorbent cotton 7 to wipe the filter plate, the spray washing mechanism 9 stops spraying water. When using the brush bristles 61 to brush the surface of the filter plate, the spray washing mechanism 9 sprays water simultaneously, so that when the brush bristles 61 brush the surface of the filter plate, water is sprayed through the spray washing mechanism 9 to achieve cleaning. The water sprayed by the spray washing mechanism 9 can be sprayed onto the absorbent cotton 7 (at this time, the absorbent cotton 7 is facing the spray washing mechanism 9), and the absorbent cotton 7 is cleaned simultaneously.

[0024] During implementation, firstly, the filter plate translation device 2 accurately transports the two adjacent filter plates to be cleaned to the gantry cleaning frame 3 on the filter press frame 1 and positions them so that the facing surfaces of the two adjacent filter plates are directly opposite the flip plate 6. Then, the drive unit 82 of the flipping mechanism 8 controls the flip plate 6 to keep the outer bristles 61 facing outward. Because the distance between the two flip plates 6 is adapted to the filter plates and they are symmetrically distributed, they can tightly fit the facing surfaces of the two adjacent filter plates respectively. Next, the lifting device 4 drives the lifting mounting plate 5, along with the tilting plate 6 and the spraying mechanism 9, to descend to the corresponding height (slightly higher than the filter plates). Then, the lifting mounting plate 5 moves from top to bottom. At this time, the bristles 61 on the outer side of the tilting plate 6 brush the facing surfaces of the two adjacent filter plates, softening the hardened dirt on the facing surfaces through physical action. Simultaneously, the conveying pipe 93 of the spraying mechanism 9 delivers water from the external water supply equipment to the spray pipe 92. The angled nozzles 94 on the outer side of the spray pipe 92 spray water onto the facing surfaces of the two adjacent filter plates, promptly rinsing away the softened dirt after brushing. After the brushing and spraying of the facing surfaces are completed, the driving part 82 of the tilting mechanism 8 drives the tilting plate 6 to rotate around the connecting frame 81. The water-absorbing cotton 7 on the inner side of the flip plate 6 is switched to face the two adjacent filter plates. The lifting device 4 then drives the lifting mounting plate 5 to move from bottom to top. The water-absorbing cotton 7 tightly covers the two adjacent filter plates and the corresponding filter cloth gaps, wiping away the residual moisture on the face surfaces of the filter plates. In order to remove moisture more thoroughly, the lifting device 4 can drive the lifting mounting plate 5 to move from top to bottom, so that the water-absorbing cotton 7 wipes away the residual moisture on the two adjacent filter plates and the corresponding filter cloth gaps again. After wiping, the filter plate translation device 2 moves the filter plates to both sides, and the lifting device 4 drives the lifting mounting plate 5 to move upward, completing the cleaning of the two facing surfaces of the two filter plates.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
