Description

Technical Field

[0001] This utility model belongs to the field of plate and frame filter technology, and specifically relates to a plate and frame filter device. Background Technology

[0002] Plate and frame filters are a type of pressurized intermittent filtration equipment with a long history. Their origins can be traced back to simple ancient filter presses, such as those used in Chinese winemaking during the Han Dynasty to separate wine and lees. Modern plate and frame filters mainly consist of filter plates and frames arranged alternately to form filter chambers, which are sealed by a clamping device. During operation, the slurry enters the filter chamber under pump pressure, the filtrate passes through the filter cloth and other filter media, and the solids are trapped to form a filter cake, thus achieving solid-liquid separation. It is particularly suitable for liquids with a concentration below 50%, low viscosity, and low residue content, and can achieve fine or semi-fine filtration requirements such as clarification, purification, and sterilization. It is widely used in the pharmaceutical, food, chemical, and environmental protection industries.

[0003] Chinese patent, publication number CN206549249U, discloses a plate and frame filter device. The device uses a guide block to slide back and forth on a guide rod through a guide device. The guide rod limits the range of motion of the guide rod through a central suspension, thereby limiting the range of motion of the filter plate. This prevents the filter plate from shaking due to excessive range of motion during the filtration or rinsing process.

[0004] In industrial production, plate and frame filters, widely used in industrial processes, accumulate a large amount of solid particles and impurities on their filter plate surfaces during operation, requiring regular cleaning and maintenance. Traditional cleaning methods primarily employ backwashing, where high-pressure water is injected backwards into the filtration system through pre-drilled channels in the filter plates. However, this method has significant limitations: because the water flow mainly follows the channels, the scouring effect on the large surfaces of the filter plates is weak, especially in structurally complex areas such as the edges and corners, where the water flow struggles to effectively cover the surfaces, resulting in incomplete removal of contaminants. Furthermore, the uneven texture of the filter plate surface hinders the uniform distribution of water flow, further reducing cleaning effectiveness. This incomplete cleaning not only affects the subsequent performance of the filter but may also shorten the lifespan of the filter plates. Utility Model Content

[0005] To address the problem of incomplete cleaning of filter plate surfaces in existing technologies, this invention provides a plate and frame filter device that uses a cleaning frame combined with cleaning components to achieve thorough cleaning of the filter plate surface.

[0016] The plate and frame filter device of this utility model has the following advantages compared with the prior art: 1. This plate and frame filter device adopts an innovative cleaning mechanism design. By incorporating a movable cleaning frame, after the plate and frame filter completes its filtration operation, the cleaning frame can be automatically controlled to move smoothly along a slide rail, allowing it to thoroughly clean the surface of each filter plate in turn. This design not only significantly improves the cleaning effect of the filter plates, ensuring no residue remains on the surface, but also effectively extends the service life of the filter plates and reduces equipment maintenance costs.

[0017] 2. The movement of the cleaning frame is precisely controlled by a second motor. This motor drives a meshing gear to rotate, which in turn meshes with a rack fixed to the frame, enabling the cleaning frame to reciprocate along the slide rails. This transmission method ensures the cleaning frame can be accurately positioned to the preset cleaning location, providing reliable positioning for subsequent cleaning operations. When the cleaning frame moves to the target filter plate position, the intelligent clamping component automatically and securely clamps the side plate of the filter plate. The cleaning frame then moves the clamped filter plate smoothly, completely separating the filter plate to be cleaned from the other filter plates. This separation process creates an ideal working space for subsequent deep cleaning.

[0018] 3. After the filter plates are separated, the cleaning unit immediately starts to clean the filter plate surface from all angles. During the cleaning process, the first motor drives the two high-pressure water pipes to make precise angle adjustments, ensuring that the water pipes are aimed at the filter plate surface at the optimal spray angle. At the same time, the sliding box's movement function allows the two water pipes to cover different areas of the filter plate, ensuring that the high-pressure water flow thoroughly rinses every corner of the filter plate. This multi-directional, multi-angle cleaning method achieves comprehensive and deep cleaning of the filter plate surface, greatly improving cleaning efficiency and quality. The entire cleaning process is highly automated, easy to operate, and has significant cleaning effects, providing a strong guarantee for the long-term stable operation of the plate and frame filter unit.

[0020] The following are specific implementation cases and appendices. Figures 1-5This invention provides a further explanation of the present invention, but it is not limited to these embodiments. The present invention provides a technical solution: a plate and frame filter device. This structure mainly includes a first mounting plate 1 and a second mounting plate 2 arranged in parallel, with a third mounting plate 7 positioned between these two mounting plates. Specifically, two parallel first sliding rods 8 are symmetrically installed in the area between the third mounting plate 7 and the second mounting plate 2. Multiple sets of movable filter plates 9 are slidably connected to these two first sliding rods 8. Simultaneously, two slide rails 3 are symmetrically arranged between the first mounting plate 1 and the second mounting plate 2, and slidable cleaning frames 4 are installed on the slide rails 3. Clamping components 5 are provided on both inner walls of the cleaning frame 4, specifically for securely clamping the filter plates 9. Furthermore, a cleaning component 6 is provided on the top of the cleaning frame 4, the main function of which is to effectively clean the filter plates 9. Through this structural design, the entire device achieves stable installation, flexible movement, and efficient cleaning of the filter plates 9.

[0021] As a preferred embodiment, furthermore, multiple sets of connecting chains 10 are evenly installed sequentially on the sidewalls of adjacent filter plates 9. These connecting chains 10 are arranged at equal intervals along the sidewalls of the filter plates 9. Whenever the filter plate 9 in front moves a certain distance, the connecting chain 10 will drive the filter plate 9 behind to move accordingly, achieving the effect of preemptively breaking up the tightly pressed filter plates 9. Sturdy side plates 11 are symmetrically installed on both sides of the filter plates 9, and these side plates 11 are firmly connected to the main structure of the filter plates 9. Each clamping component 5 precisely corresponds to the position of a side plate 11. The clamping component 5 adopts a special design to firmly and stably clamp the corresponding side plate 11, ensuring the stable operation of the entire filtration system. A reliable connection structure is formed between the clamping component 5 and the side plate 11, providing necessary support and fixation for the filter plates 9.

[0022] As a preferred option, further in the equipment structure, the third mounting plate 7 serves as a crucial supporting component, with the cylinder 12, the power unit, securely mounted on its surface. The output rod of the cylinder 12 is made of high-strength material, and its length is precisely calculated to fully extend through the pre-drilled holes in the third mounting plate 7. At the end of the output rod, a push plate 13, an actuator, is specially designed and installed. The size and shape of the push plate 13 are optimized to ensure that a uniform and effective compressive force is applied to the filter plate 9. This structural design allows the cylinder 12 to perform precise compressive operations on the filter plate 9 via the push plate 13, thereby ensuring the stable operation of the entire filtration system.

[0023] As a preferred embodiment, the clamping component 5 is further composed of key components such as a fixing plate 51, a connecting box 52, a first clamping block 53, and a second clamping block 55. Specifically, two fixing plates 51 are symmetrically installed on the outer walls of both sides of the cleaning rack 4, located on the left and right sides of the cleaning rack 4, respectively. Simultaneously, two connecting boxes 52 are also installed on the inner walls of both sides of the cleaning rack 4, and these connecting boxes 52 are securely connected to the outer fixing plates 51 by welding or bolts. Each connecting box 52 has a rotating connection structure at its top, connecting to the first clamping block 53 and the second clamping block 55 respectively, allowing the two clamping blocks to rotate freely within a certain angle range. To ensure clamping stability and automatic reset function, a first spring 54 is specially provided between the first clamping block 53 and the connecting box 52, and a second spring 56 is also installed between the second clamping block 55 and the connecting box 52. Both springs are fixed by welding, ensuring both reliable connection and providing necessary elastic support.

[0024] As a preferred embodiment, the cleaning component 6 is further composed of key components such as the mounting cavity 62, the second slide bar 63, the sliding box 64, the first water pipe 612, and the second water pipe 613. Specifically, a rectangular mounting cavity 62 is specially designed and opened at the inner top of the cleaning frame 4, providing a stable mounting space for the entire cleaning mechanism. Inside the mounting cavity 62, a robust second slide bar 63 is precisely installed horizontally. This slide bar is made of high-quality steel and its surface is specially treated to ensure good sliding performance. A freely sliding sliding box 64 is fitted onto the second slide bar 63. This sliding box 64 adopts a lightweight design, ensuring both mobility and sufficient structural strength. Of particular note is that two sets of four water pipe systems are symmetrically installed on both sides of the sliding box 64, including two first water pipes 612 and two second water pipes 613. The first water pipe 612 is mainly responsible for high-pressure rinsing of the surface of the filter plate 9 to ensure thorough removal of surface dirt; while the second water pipe 613 is specifically designed for precise cleaning of the openings in the filter plate 9, and its specially designed nozzle can effectively remove blockages inside the openings. This dual-pipe design ensures a comprehensive cleaning effect for the filter plate 9.

[0025] As a preferred option, a further step involves securely mounting a metal outer casing 61 on the top sidewall of the cleaning rack 4. This casing 61 is manufactured using a rust-proof treatment process, resulting in a smooth and flat outer surface. A high-performance drive motor with waterproof and dustproof characteristics is precisely mounted on the front of the casing 61. The internal space of the casing 61 is precisely designed, in which a precision worm gear 67 is rotatably connected via bearing housings. The surface of the worm gear 67 undergoes a special hardening treatment to improve wear resistance. The output shaft of the drive motor extends into the interior of the casing 61 via a coupling, achieving a reliable mechanical connection with one end of the worm gear 67. The helical teeth of the worm gear 67 form a precise meshing transmission relationship with a specially designed worm wheel 66, which is made of a high-strength alloy material. A precision lead screw 65 is fixedly mounted at the center of the worm gear 66. One end of the lead screw 65 is rotatably connected to the inner wall of the housing 61 via a rolling bearing, while the other end extends through a sealing device into the mounting cavity 62 and is rotatably connected to the inner wall of the mounting cavity 62 via a bearing seat. A specially designed sliding box 64 is precisely fitted onto the lead screw 65 via internal threads, forming a stable threaded transmission connection. The entire transmission system is rationally laid out, and the components fit tightly together, ensuring the smoothness and reliability of the transmission process.

[0026] As a preferred option, the bottom structure of the sliding box 64 is ingeniously designed, with two sets of slots for different functions symmetrically opened on its left and right sides, including two first side slots 68 and two second side slots 69. The arrangement of these slots fully considers space utilization and functional requirements. Inside the sliding box 64, rotatable first rotating pipes 610 and second rotating pipes 612 are installed respectively. These two rotating pipes can rotate flexibly through bearings and other connecting parts. Among them, the two first water pipes 612 are firmly connected to the first rotating pipes 610 by flanges or welding, while the two second water pipes 613 are fixed to the second rotating pipes 612 in the same way. This arrangement achieves a reliable connection between the water pipes and the rotating pipes. It is particularly noteworthy that the first water pipes 612 and the first side slots 68 are arranged in a one-to-one correspondence, with each first water pipe 612 precisely embedded in the corresponding first side slot 68; similarly, the second water pipes 613 and the second side slots 69 are also in a one-to-one correspondence, with each second water pipe 613 accurately installed in the corresponding second side slot 69. To ensure the flexible movement of the water pipes, the sides of the first side groove 68 and the second side groove 69 are specially designed to extend into the side wall of the sliding box 64. This structural feature allows the first water pipe 612 and the second water pipe 613 to rotate horizontally as needed, either extending outwards for use or being completely retracted into the internal space of the sliding box 64, thus achieving efficient use of space and convenient operation of the equipment.

[0027] As a preferred embodiment, a first motor 17 is securely mounted on the outer wall of the sliding housing 64, with its power output shaft extending through the housing wall into the interior space of the sliding housing 64. A precision third gear 16 is fixedly mounted at the end of the output shaft of the first motor 17. Simultaneously, a first gear 14 is mounted on the outer circumferential surface of the first rotating tube 610 located inside the sliding housing 64, secured by welding or bolts; similarly, a matching second gear 15 is also fixedly mounted on the outer circumferential surface of the second rotating tube 612. These three gears form a precise meshing relationship: the third gear 16 maintains a stable meshing state with both the first gear 14 and the second gear 15, ensuring the synchronicity and accuracy of power transmission.

[0028] The front end of the first rotating tube 610 extends through the front wall of the sliding box 64 and protrudes outward; similarly, the front end of the second rotating tube 612 also extends out of the sliding box 64 in the same manner. At the extended end of the first rotating tube 610, a first water inlet pipe 18 is connected via a flange or threaded connection; while at the extended end of the second rotating tube 612, a second water inlet pipe 19 is connected. A long, narrow through-hole 20 is provided horizontally on the front side panel of the cleaning rack 4. This elongated hole 20 allows the first water inlet pipe 18 and the second water inlet pipe 19 to slide freely through while maintaining a sealing performance.

[0029] The entire piping system forms two independent but interconnected fluid channels: the first inlet pipe 18, the first rotating pipe 610, and the connected first water pipe 612 constitute the first complete fluid passage; while the second inlet pipe 19, the second rotating pipe 611, and the connected second water pipe 613 form the second independent fluid passage. These two passage systems maintain independent operation while achieving synchronous control through a gear transmission system, ensuring the coordinated operation of the entire device.

[0030] As a preferred option, the top structure of the cleaning rack 4 is rationally designed and fully functional, with three important components installed sequentially on top: a water tank 21, a water pump 22, and a support frame 23. The water tank 21, acting as a water storage device, is seamlessly connected to the water pump 22 via pipes. The water pump 22, through a branch design, is simultaneously connected to the first inlet pipe 18 and the second inlet pipe 19, forming a complete water supply system. Regarding the overall frame, the tops of the first mounting plate 1 and the second mounting plate 2 jointly support a sturdy top plate 25, providing stable upper support for the entire device. Particularly noteworthy is the dedicated installation of the starting end of a cable chain 24 on the top of the support frame 23. The other end of the cable chain 24 is securely fixed to the top of the top plate 25. This meticulously designed cable chain system effectively protects the internal wiring, preventing damage from movement or friction during equipment operation and ensuring long-term stable operation of the equipment.

[0031] As a preferred embodiment, the cleaning rack 4 is further equipped with symmetrical first connecting plates 26 on both sides. These first connecting plates 26 are made of high-strength metal to ensure structural stability. Four rotating shafts 27 are evenly distributed at equal intervals on the plane of the first connecting plates 26. These rotating shafts 27 are rotatably connected to the first connecting plates 26 via precision bearings. One end of each rotating shaft 27 extends into the internal space of the cleaning rack 4, and a wear-resistant rubber roller 28 is fixedly fitted at the end. These rollers 28 maintain close rolling contact with the surface of the slide rail 3. To enhance the overall structural support, a second connecting plate 29 is also fixedly installed at the bottom of the first connecting plate 26. This connecting plate adopts an L-shaped design to increase the force-bearing area. A high-performance second motor 30 is installed on one side of the second connecting plate 29. This motor is equipped with a reduction gear to improve torque output. The output end of the second motor 30 is connected to a dynamically balanced output shaft 31. This output shaft 31 passes through the interior of the cleaning rack 4 via a sealed bearing, and a high-precision meshing gear 32 is fixedly fitted at its end. Meanwhile, a rack 33 that has undergone quenching treatment is fixedly installed at the bottom of the slide rail 3. The rack 33 and the meshing gear 32 form a precise meshing transmission relationship to ensure the smoothness and reliability of power transmission.

[0032] The filter plate, cylinder, motor, water pump, and water pipe in this case are existing technologies, and any filter plate, cylinder, motor, water pump, and water pipe that meet the requirements of this case are acceptable.

[0033] The specific types or circuit structures of the controllers for the electrical components mentioned in this application, as well as the circuit connection relationships between the electrical components and the accurate coordinated control of multiple power components, are all prior art. Therefore, the above content will not be elaborated upon in this application.

[0034] Working Principle: All electrical components in this application are externally connected to a power supply and control switch during use. After installation, first check the installation, fixation, and safety precautions before use. During operation, the cylinder 12 drives the push plate 13 to apply uniform pressure to the filter plate 9, forming a series of well-sealed filter chambers. To ensure reliable sealing under high pressure, all critical sealing parts are sealed with high-quality silicone rubber rings. During operation, a high-pressure pump delivers the suspension to be treated into the filter chamber. Under system pressure, the filtrate passes through the filter medium pre-installed on the filter plate, while solid particles in the suspension are efficiently trapped on the surface of the filter medium, gradually forming a dense filter cake layer. The filtered clear liquid is collected through a carefully designed groove channel system on the filter plate and finally discharged from the outlet. After completing the filtration process, the pressure of the cylinder 12 is released to return the push plate 13 to its original position, and then the dedicated cleaning rack 4 is activated to thoroughly clean the filter plate 9.

[0035] The specific operation of the cleaning process is as follows: First, the second motor 30 is started, driving the meshing gear 32 to rotate through its output shaft 31. The meshing action of the meshing gear 32 and the rack 33 drives the cleaning frame 4 to move smoothly along the slide rail 3. When the cleaning frame 4 moves to the position of the first filter plate 9, the second clamping block 55 on it will rotate downwards due to the squeezing action of the side plate 11. After the cleaning frame 4 continues to move forward and the second clamping block 55 completely passes the first side plate 11, the second clamping block 55 automatically springs back to its original position under the elastic restoring force of the second spring 56. Then, the second motor 30 is controlled to reverse, causing the meshing gear 32 to drive the cleaning frame 4 to move back a certain distance. At this time, the side plate 11 pushes the filter plate 9 forward under the action of the second clamping block 55, and the adjacent filter plates 9 gradually separate through the linkage action of the connecting chain 10. After the first filter plate 9 is moved to the predetermined cleaning position by the cleaning frame 4, the first motor 17 is immediately started, driving the third gear 16 to rotate. The third gear 16 simultaneously drives the first gear 14 and the second gear 15 to rotate. The first gear 14 drives the first rotating tube 610 to rotate, while the second gear 15 drives the second rotating tube 611 to rotate synchronously, so that the first water pipe 612 and the second water pipe 613 on both sides can be accurately rotated to the vertically downward working position.

[0036] Next, the dedicated motor installed on the outside of the outer casing 61 is started, which drives the worm gear 67 to rotate. The meshing transmission between the worm gear 67 and the worm wheel 66 drives the lead screw 65 to rotate, which in turn drives the sliding box 64 to slide smoothly along the second slide rod 63. When the sliding box 64 moves to the opening position on the left side of the filter plate 9, it stops moving. At this time, water is supplied to the second water inlet pipe 19 by the water pump 22, so that the second water pipe 613 can perform directional spray washing on the opening on the left side of the filter plate 9. After cleaning this part is completed, the lead screw 65 is controlled to rotate to move the sliding box 64 to the right. During the movement, water is continuously supplied to the first water inlet pipe 18 by the water pump 22, and the first water pipe 612 is used to perform a comprehensive high-pressure rinse on the entire surface of the filter plate 9. When the sliding box 64 moves to the opening position on the right side of the filter plate 9, it stops moving again, and water is supplied to the second water pipe 613 for a final rinsing operation to ensure that the opening on the right side of the filter plate 9 is thoroughly cleaned.

[0037] After cleaning a single filter plate 9, the meshing gear 32 is restarted to move the cleaning frame 4 forward, pushing the cleaned filter plate 9 to a position where it is fully in contact with the push plate 13. During this process, the first clamping block 53 on the cleaning frame 4 is squeezed downward by the push plate 13 and rotates downward. Then, the cleaning frame 4 is controlled to move backward. When the first clamping block 53 passes the side plate 11 of the first filter plate 9, the first spring 54 rebounds the first clamping block 53, and the same cleaning operation can begin for the second filter plate 9. The entire cleaning process is automated, ensuring that each filter plate 9 receives thorough and efficient cleaning.
