Description

Technical Field

[0001] This invention relates to the field of filter press technology, specifically a filter cloth rotating suspension device. Background Technology

[0002] Filter cloth is a key component of a filter press, used for filtering solid particles and separating liquids. The selection and use of filter cloth directly affect the filtration efficiency and effect of the filter press. Filter cloth materials include: Polyester: abrasion-resistant and corrosion-resistant, suitable for most industrial applications. Polypropylene: acid and alkali-resistant, suitable for the chemical industry. Nylon: high strength, suitable for high-pressure and high-temperature environments. Polytetrafluoroethylene (PTFE): high-temperature and corrosion-resistant, suitable for extreme environments. Cotton cloth: suitable for low-pressure, low-temperature, and low-corrosion environments. During use, the following points should be noted for the installation and maintenance of filter cloth: Installation: Ensure the filter cloth is flat, wrinkle-free, and securely installed. Cleaning: Clean the filter cloth regularly to remove blockages and restore filtration efficiency. Replacement: Replace the filter cloth promptly according to usage and wear. Inspection: Regularly inspect the filter cloth for wear and damage, and repair or replace it as needed.

[0003] The existing patent authorization number is CN217526496U, which discloses a filter cloth suspension device for a fully automatic chamber filter press. The device is installed on the chamber plate of the fully automatic chamber filter press and includes: a suspension frame, filter cloth, adjustment components, and hanging rods. The suspension frames are rotatably mounted in pairs between adjacent chamber plates, and a hanging rod is hung between each pair of suspension frames. The hanging rod body is detachably connected to one side of the filter cloth. A pair of filter cloths is sandwiched between two adjacent chamber plates, and the filter cloth has a connecting hole with an embedded elastic element in the center, used to connect with the water inlet in the center of the chamber plate when the two adjacent chamber plates are attached. Adjustment components are arranged in pairs between each pair of suspension frames, and each adjustment component is coupled to the surface of a filter cloth, used to flatten and separate the two filter cloths when the two adjacent chamber plates are separated. The device detachably connects the filter cloth to a pair of hanging rods suspended within a suspended frame. When replacing the filter cloth, simply remove the hanging rod from the suspended frame and detach the filter cloth from the rod for quick replacement. Analysis of this device reveals that its main function is to improve the ease of filter cloth replacement by using a detachable connection method for each component. However, in practical use, firstly, the size of the filter cloth installed is fixed, requiring the removal and replacement of a new cloth each time, making it impossible to adjust according to the required filtration area; thus, each filter cloth has a short lifespan. Secondly, it cannot automatically clean impurities from the filter cloth, often requiring external tools or manual handling, which severely impacts the normal operation of the filter press. Finally, the complex structure makes it difficult to quickly fix and separate the filter cloth, resulting in high operational difficulty. Therefore, in view of the above-mentioned problems, this technical solution proposes a filter cloth rotation suspension device. Summary of the Invention

[0004] The purpose of this invention is to provide a filter cloth rotation suspension device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a filter cloth rotation suspension device, comprising a filter cloth, a suspension frame I, and a suspension frame II; the filter cloth is suspended on the outside of a filter plate by an external auxiliary component, which controls the filter cloth to detach from the filter plate and to rotate up and down. The external auxiliary component includes suspension frames I and II with adjustable angles. The filter cloth is rolled and connected in series between the outside of suspension frames I and II. A top swinging component mounted on a filter press plate is rotatably connected to the top of suspension frames I and II. A bottom adjusting component is rotatably connected between the bottom of suspension frames I and II. The bottom adjusting component horizontally extends and retracts in coordination with the top swinging component to adjust the angle between suspension frames I and II, thereby adjusting the tilt filtration angle of the filter cloth suspended on suspension frames I or II. The first and last ends of the filter cloth are respectively detachably connected to upper connecting rods via filter cloth fasteners, located on suspension frames I and II. The lower filter cloth is wound around and passed through the lower connecting rod, pivot I, pivot II, and the upper connecting rod located inside the suspension frame I and suspension frame II. A transmission chain top swing component is connected between the upper and lower connecting rods. The top of the transmission chain top swing component on the suspension frame I is connected to a rotating power component. The rotating power component drives the transmission chain top swing component below it to rotate. Then, with the rotation of the filter cloth, upper connecting rod, lower connecting rod, pivot I, and pivot II, the rotational position of the filter cloth is adjusted. This allows for the selection of a suitable size filter cloth to be placed on the outside of the filter plate at the suspension frame II when filtering different amounts of filter material. At the same time, according to the wear and tear of the filter cloth, the filtration position is continuously changed by rotating the filter cloth, thereby increasing the service life of each filter cloth. Furthermore, by adjusting the angle between the suspension frame I and suspension frame II, the appropriate tilt angle of the filter cloth can be controlled for filtration, thereby increasing the filtration accuracy and the scope of application. The vibration cleaning mechanism is located inside the filter cloth. The inner end of the vibration cleaning mechanism is rotatably connected to a rotating shaft on one side. The rotating shaft includes pivot I, pivot II, and chain teeth connected to the top of the suspension frame II and rotatably connected to the top swing component of the transmission chain. When the rotating power component controls the filter cloth to rotate and move, it synchronously drives the vibration cleaning mechanism to run, performing lateral vibration and rolling cleaning on the moving filter cloth. This achieves a certain degree of vibration cleaning of impurities adhering to the filter cloth during filtration each time the filter cloth is repositioned, thereby improving the efficiency of subsequent filtration. Thus, this device realizes the function of simultaneously vibrating and cleaning the filter cloth when it is rotated and adjusted, thereby further improving the service life of the filter cloth.

[0006] Compared with the prior art, the beneficial effects of the present invention are: by setting up a bottom adjustment component, it is easy to adjust the angle of the suspension frame I and the suspension frame II, thereby adjusting the filtration angle of the filter cloth. At the same time, the filter cloth fasteners are used to wrap and suspend a single filter cloth between the suspension frame I and the suspension frame II. While not affecting its normal filtration use, the filtration position of the filter cloth can be adjusted as needed, so as to increase the service life of a single filter cloth and reduce the cost of use. At the same time, the automatic rotation adjustment is simple to operate and highly practical. By controlling the rotation and movement of the filter cloth, and using the transmission action of the transmission belt to control the operation of the vibrating plate and cleaning roller brush in contact with the filter cloth, the filter cloth is subjected to cyclic vibration and rolling cleaning. This achieves automated cleaning of the filter cloth during operation, reduces its wear, increases its service life, and further reduces the cost of filtration. By using a single filter cloth for winding and suspension, and fixing it with filter cloth fasteners, the system achieves easy installation, disassembly, replacement, and flexible use.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Please see Figure 1 A filter cloth rotation suspension device includes a filter cloth 2, a suspension frame I 11, and a suspension frame II 12. The filter cloth 2 is suspended from the outside of a filter plate by external auxiliary components. The external auxiliary components control the filter cloth 2 to detach from the filter plate and control the filter cloth 2 to rotate up and down. The external auxiliary components include suspension frames I 11 and II 12 with adjustable angles. The filter cloth 2 is rolled and connected in series between the outside of suspension frames I 11 and II 12. The top of suspension frames I 11 and II 12 is rotatably connected to a mounting device. The top swing member 14 on the filter press plate and the bottom of the suspended frame I 11 and the suspended frame II 12 are rotatably connected by a bottom adjusting member 19. The bottom adjusting member 19 horizontally extends and retracts in coordination with the top swing member 14, thereby adjusting the included angle between the suspended frame I 11 and the suspended frame II 12, and thus adjusting the tilt filtration angle of the filter cloth suspended on the suspended frame I 11 or the suspended frame II 12. The first and last ends of the filter cloth 2 are respectively detachably connected to the upper connecting rod 1 by the filter cloth fastener 35, located on the suspended frame I 11 and the suspended frame II 12. The filter cloth 2 at the lower part of the 12 is wound through and rotated through the lower connecting rod 3, pivot I 4, and pivot II 5 located on the lower side of the suspended frame I 11 and suspended frame II 12. A transmission chain 13 is connected between the upper connecting rod 1 and the lower connecting rod 3 located on the inner side of the suspended frame I 11 and suspended frame II 12. A rotating power component is connected to the top of the transmission chain 13 located on the suspended frame I 11. The rotation power component drives the transmission chain 13 below it to rotate. Then, the filter cloth, upper connecting rod 1, lower connecting rod 3, pivot I 4, and pivot II 5 are connected. With the rotation of 5, the position of the filter cloth 2 can be adjusted by rotation. This allows for the selection of a suitable size of filter cloth 2 to be placed on the outside of the filter plate at the suspension frame II 12 when filtering different amounts of filter material. At the same time, the filter cloth 2 can be rotated to continuously change the filtration position according to its wear and tear, thereby increasing the service life of each filter cloth 2. Furthermore, by adjusting the angle between the suspension frame I 11 and the suspension frame II 12, the filter cloth 2 can be controlled to have a suitable tilt angle for filtration, thereby increasing the filtration accuracy and the scope of application. The vibration cleaning mechanism 23 is located inside the filter cloth 2. The inner end of the vibration cleaning mechanism 23 is rotatably connected to a rotating shaft on one side. The rotating shaft includes a pivot I 4, a pivot II 5, and a chain tooth 55 connected to the top of the suspension frame II 12 and rotatably connected to the transmission chain 13. When the rotating power component controls the rotation of the filter cloth 2, it synchronously drives the vibration cleaning mechanism 23 to run, performing lateral vibration and rolling cleaning on the moving filter cloth. This achieves a certain degree of vibration cleaning of impurities adhering to the filter cloth 2 during filtration each time the position of the filter cloth is adjusted, thereby improving the efficiency of subsequent filtration. Thus, this device realizes the function of simultaneously vibrating and cleaning the filter cloth 2 when it is rotated and adjusted, thereby further improving the service life of the filter cloth 2.

[0019] In this embodiment of the invention, the top end of the transmission chain 13 is engaged with the chain teeth 55, and the bottom end is fixedly connected to the end of the filter cloth 2 through a connecting rod. That is, when the rotating power component is running, it drives the transmission chains 13 on both sides to move synchronously, thereby rotating and adjusting the position of the filter cloth 2. The rotating power component includes a set of servo motors 10 located at the top of the suspended frame I11. The output end of the servo motors 10 is connected to a bevel gear I16. A bevel gear II17 is vertically meshed on one side of the bevel gear I16. A chain tooth 55 is mounted on the rear side of the bevel gear II17 via a connecting rod. Simultaneously, a set of chain teeth 55 is also located at the same height at the top of the suspended frame II12. The chain teeth 55 on both sides are respectively meshed with and connected to a transmission chain 13. The filter cloth 2 is positioned below the bottom of the suspended frame I11. Starting from connecting rod 3, it rolls through pivot I4 on the lower side of suspended frame I11 and pivot II5, then upwards through upper connecting rod 1 on the upper side of suspended frame I11, and then continues downwards through pivot I4 and lower connecting rod 3 on the lower side of suspended frame II12. Then it passes through pivot II5 upwards and connects with upper connecting rod 1 on the upper side of suspended frame II12, thus forming a rotational movement of filter cloth 2 between suspended frame I11 and suspended frame II12. At the same time, the filtration position of filter cloth 2 is adjusted according to the filtration requirements.

[0020] In one embodiment of the present invention, see [reference] Figure 1 , Figure 7 The top swing component 14 includes two fixed blocks that are fixedly installed at the top center of the suspension frame I11 and the suspension frame II12. Each fixed block is rotatably connected to two swing rods I15. The top ends of the swing rods I15 are rotatably connected to a fixed base through a rotating shaft. That is, the top of the suspension frame I11 and the top of the suspension frame II12 are rotatably connected by the two sets of swing rods I15. Specifically, the bottom adjustment component 19 includes a set of horizontally distributed cylinders 20. The output end of the cylinders 20 is connected to a piston rod. The end of the piston rod and the end of the cylinders 20 away from the piston rod are rotatably connected to a swing shaft 21. The two swing shafts 21 are rotatably connected to the connecting posts 18 on the bottom ends of the suspension frame I 11 and suspension frame II 12. That is, by utilizing the rotatable connection between the swing shafts 21 and the connecting posts 18, and in conjunction with the lateral extension and retraction of the cylinders 20, the angle of the bottom sides of the suspension frame I 11 and suspension frame II 12 is adjusted. At the same time, in conjunction with the swing rod I 15 on the top of the suspension frame I 11 and suspension frame II 12, the placement position of the filter cloth 2 on the outside of the suspension frame I 11 and suspension frame II 12 is adjusted, and its adaptability to the filtration of filter media of different contents or particle sizes is controlled.

[0021] Among them, the top of the filter cloth 2 is connected to the upper connecting rod 1 by a winding method, and the filter cloth fastener 35 is placed on the lower side of the upper connecting rod 1 to directly clamp and fix the filter cloth 2. See Figure 6The filter cloth fastener 35 includes L-shaped clamping plates 45 symmetrically distributed on both sides. The filter cloth 2 to be fastened is placed between the two L-shaped clamping plates 45 for clamping and fixing. The side of the L-shaped clamping plate 45 that contacts the filter cloth 2 is provided with clamping mouth 48. The staggered clamping of the clamping mouth 48 increases the fastening and clamping stability of the filter cloth 2. The ends of the L-shaped clamping plates 45 on both sides are provided with shrinkable connecting assemblies. The shrinkable connecting assemblies include a slide groove 52 opened on the side wall of the L-shaped clamping plate 45. A movable end rod 54 is slidably connected inside the slide groove 52. The two ends of the movable end rod 54 extend to the outside of the slide groove 52. A positioning end rod is rotatably connected to the end wall of the L-shaped clamping plate 45 located on the upper side of the slide groove 52. The movable end rods 54 and the fixed end rods on both sides are rotatably connected with swing rods II 50 in an alternating manner. The two sets of swing rods II 50 are rotatably connected in the middle through a central rotating shaft 53. When the L-shaped clamping plates 45 on both sides are controlled to move relative to each other, the two sets of swing rods II 50 swing relative to each other. At the same time, the movable end rods 54 are controlled to move inside the slide groove 52, thereby keeping the L-shaped clamping plates 45 on both sides able to run synchronously and smoothly. A manual drive assembly is located inside the L-shaped clamping plates 45 on both sides near the shrink connector. The rotation of the manual drive assembly causes the L-shaped clamping plates 45 on both sides to move relative to each other. The manual drive assembly includes a fastening screw 49 threadedly connected to the side wall of one of the L-shaped clamping plates 45. The end of the fastening screw 49 facing the other L-shaped clamping plate 45 is connected to a rotating rod 47 that interacts with and passes through the wall of the L-shaped clamping plate 45. A positioning ring is fitted on the outside of the rotating rod 47 to control the movement of the fastening screw 49, causing the L-shaped clamping plates 45 on both sides to move closer or further apart. A handle 46 is installed on the outer end of the rotating rod 47. The rotating rod 47 is rotated by manually rotating the handle 46. In conjunction with the positioning ring, the distance between the L-shaped clamping plates 45 on both sides is adjusted, thereby clamping and fixing the filter cloth 2 placed between the clamping nozzles 48.

[0022] As a preferred embodiment of the present invention, see [reference]. Figures 1-5The vibration cleaning mechanism 23 includes a set of drive shafts 24. One end of the drive shaft 24 is rotatably connected to the rotating shaft via a transmission belt 22. Two positioning blocks 25 move through both sides of the drive shaft 24. The positioning blocks 25 are mounted on the suspension frame I 11 or suspension frame II 12 via connecting rods or other structures. A central shaft 26 is provided in the middle of the drive shaft 24. The central shaft 26 rotates synchronously with the rotation of the drive shaft 24. Two swing plate frames 27 are symmetrically installed on the outer circumferential walls of both sides of the central shaft 26. A shaft is rotatably connected between the swing plate frames 27. A connecting bushing 28 is fitted on the shaft. A telescopic component is connected to the outer circumferential wall of the connecting bushing 28. A U-shaped connecting frame 29 is swayably connected to the end of the telescopic component via the shaft. A buffer is installed on the side of the U-shaped connecting frame 29 away from the connecting bushing 28. A sleeve 31 is fitted onto the punch rod 30 and the buffer rod 30. A vibrating plate 34 is fixedly installed at the end of the sleeve 31. A central spring 32 is elastically connected inside the sleeve 31 between the end of the buffer rod 30 and the vibrating plate 34. At the same time, two sets of side springs 33 are symmetrically elastically connected between the positioning blocks 25 on both sides and the vibrating plate 34. When the central shaft 26 rotates and drives the swing plate frame 27 to rotate, it generates a swing amplitude. Then, under the connection of the telescopic component, it drives the buffer rod 30 to generate a reciprocating swing within a certain stroke of the central spring 32 inside the sleeve 31, thereby controlling the vibrating plate 34 to vibrate continuously. At this time, the outer side of the vibrating plate 34 contacts the filter cloth 2, thereby realizing that the filter cloth 2 is vibrated during the rotation and movement, thereby shaking and removing the impurities adhering to its surface. To further improve the ability of the filter cloth 2 to clean surface impurities during rotation, a rotating sleeve 36 is fitted at one end of the drive shaft 24. A cleaning roller brush 39 is rotatably connected to one end of the rotating sleeve 36 via a central transmission belt 38. Multiple sets of cleaning roller brushes 39 are provided, and guide rods 37 are installed at both ends. One side of the guide rods 37 is rotatably connected to each other via a side transmission belt 40. The cleaning roller brushes 39 are distributed in contact with the filter cloth 2. That is, when the drive shaft 24 rotates, it synchronously drives the rotating sleeve 36 to rotate. Then, under the rotational connection of the central transmission belt 38, it drives one set of cleaning roller brushes 39 to rotate. Then, under the rotational connection of the side transmission belt 40, it drives multiple sets of cleaning roller brushes 39 to rotate simultaneously, thereby rolling and cleaning the moving filter cloth 2. Then, in conjunction with the vibration of the vibrating plate 34, the filter cloth 2 is thoroughly cleaned. Specifically, the telescopic component includes a rotating block 44 located inside the side wall of the connecting bushing 28. The rotating block 44 has a rotating hole 43 rotatably connected inside, and a screw cylinder 41 is connected to the outside of the rotating hole 43. A screw rod 42 is threadedly connected inside the screw cylinder 41. The top of the screw rod 42 is rotatably connected to the end of the U-shaped connecting frame 29. By manually rotating the screw cylinder 41, the rotating block 44 is controlled to rotate inside the rotating hole 43, thereby controlling the depth of the screw rod 42 inside the screw cylinder 41. This adjusts the length of the U-shaped connecting frame 29 from the connecting bushing 28, and adjusts the squeezing force of the centering spring 32 when the central shaft 26 rotates, thereby adjusting the vibration amplitude of the vibrating plate 34. The vibrating plate 34 is provided with perforated plates 56 evenly to ensure that the vibrating plate 34 does not affect the normal filtration of the filter cloth 2 when it vibrates in contact with the filter cloth 2. It should be noted that the contact amplitude between the cleaning roller brush 39 and the filter cloth 2 is greater than the amplitude of the vibration plate 34 controlling the vibration of the filter cloth 2, ensuring that the cleaning roller brush 39 can perform real-time contact cleaning of the filter cloth 2.

[0023] The working principle of this invention is as follows: In the idle state of this device, all the aforementioned driving components, referring to power elements, electrical components, and compatible power supplies, are connected via wires. The electrical connections are completed in sequence between the working components. The detailed connection methods are well-known in the art. The following mainly describes the working principle and process, without further explanation of the electrical control. During use, the suspended frame I 11 and suspended frame II 12 are pre-installed on the filter press. Then, the first and last ends of the filter cloth 2 are clamped and fixed to the upper connecting rod 1 on the upper part of the suspended frame I 11 and suspended frame II 12 using filter cloth fasteners 35. Next, the filter cloth 2 is wound around the pivot I 4, pivot II 5, and chain teeth 55 on the suspended frame I 11 and suspended frame II 12 in a complete circle. Simultaneously, the filter cloth 2 is placed outside the filter plate. Then, during use, the filter cloth 2... According to the required filtration angle, the piston rod at the end of the filter cloth 2 can be extended and retracted by starting the cylinder 20. Then, under the rotational connection of the swing shaft 21 and the connecting column 18, the placement angle of the filter cloth 2 can be adjusted to fully filter the filter material. At the same time, when the filter cloth 2 rotates and moves, the size of its straight-face filtration can be adjusted according to the usage and consumption of the filter cloth 2 and the area required for filtration. During the rotation and movement, the drive shaft 24 is driven to rotate by the transmission connection of the transmission belt 22. Then, under the swing operation of the structure such as the central shaft 26, buffer rod 30, central spring 32, and side spring 33, the vibrating plate 34 is driven to circulate and vibrate the filter cloth 2. Under the connection of the rotating sleeve 36, multiple cleaning roller brushes 39 are driven to roll and clean the inner side of the filter cloth 2. This allows for quick and convenient cleaning of the filter cloth 2, thereby improving its service life.

[0024] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
