Description

Technical Field

[0001] This application relates to the field of filter press technology, and more particularly to a filter press that facilitates material removal. Background Technology

[0002] A filter press is a device used for solid-liquid separation. By applying pressure, solid particles in a suspension are trapped on the surface of a filter cloth, while the liquid is discharged through the filter cloth, ultimately forming a filter cake with low moisture content. It is widely used in chemical, mining, sewage treatment, food processing and other fields, and is a key dewatering equipment in industrial production. However, in filter press operation, some materials are highly viscous and easily adhere to the surface of the filter cloth or filter plate, making dewatering difficult and requiring manual dewatering. During manual dewatering, operators need to be in close contact with the filter press and the filter cake, which poses a certain safety risk. In addition, the speed of manual dewatering is relatively slow, causing intermittent stops in the entire production process, prolonging the production cycle and reducing production efficiency. Utility Model Content

Supports are provided on both sides of the machine body and displacement drive components are installed. The displacement drive components include supports, and two sets of supports are provided and distributed opposite to each other on the two sets of supports. The supports have cavities and are rotatably provided with lead screw components. One end of the lead screw components extends to the outside of the supports and is connected to a first motor component.

[0006] A mounting base is connected to the lead screw assembly. A support plate is set between two sets of mounting bases and a push rod assembly is installed thereon. The piston end of the push rod assembly passes through the support plate and is connected to a bearing seat. The bearing seat has a cavity for accommodating the filter plate. Elastic support components are set on both sides of the cavity. The elastic support components include elastic elements. One end of the elastic element is connected to the cavity and the other end is connected to a clamping plate. An inclined part is set at the bottom of the clamping plate. When the filter plate is located in the cavity, the clamping plate abuts against the filter plate. Through the cooperation of the lead screw assembly and the first motor assembly, the push rod assembly drives the filter plate to move relative to each other.

[0007] Scraper components are provided on both sides of the bottom of the support base. The scraper components include scraper plates, which abut against the sides of the filter plate. Through the cooperation of the push rod components, the scraper components can move relative to the filter plate along its length.

[0008] In one embodiment, the scraper component further includes a receiving plate disposed at the bottom of the support seat. The receiving plate has a groove, and a shaft is rotatably disposed in the groove. The scraper has an opening and is fixed on the shaft. When the shaft rotates, the scraper rotates relative to the shaft, so that the scraper and the receiving plate are parallel or form an angle.

[0009] In one embodiment, flushing components are provided on both sides of the support base. The flushing components include support rod components, one end of which is connected to the support base, and the other end is connected to a pipe body. One end of the pipe body is provided with a liquid inlet interface connected to an external water source.

[0010] The pipe body is equipped with several spaced nozzles, with the output ends of the nozzles facing the filter plate. Through the cooperation of the push rod component, the carrier seat drives the rinsing assembly to move relative to each other.

[0011] In one embodiment, the scraper component further includes a second motor component, which is disposed on one side of the receiving plate. One end of the shaft is connected to the output end of the second motor component via a coupling. Through the cooperation of the second motor component, the shaft can drive the scraper to rotate.

[0012] In one embodiment, the support base has a receiving groove, and a portion of the receiving plate is movably disposed within the receiving groove;

[0013] The support base has mounting holes, and the receiving plate is provided with limiting holes that match the mounting holes. Several limiting holes are provided and are distributed at intervals along the length direction of the receiving plate.

[0014] By moving the receiving plate within the receiving groove, the mounting hole is aligned with one of the set of limiting holes. When the mounting hole and the limiting hole are aligned, a pin is connected to fix the receiving plate onto the bearing seat.

[0015] In one embodiment, the support rod component includes a fixed rod and a movable rod. The fixed rod is disposed on the base, and the movable rod is connected to the tube body. The fixed rod has a placement groove, and a portion of the movable rod is movable within the placement groove.

[0018] This application discloses a filter press device for easy material removal. After filtration, adjacent filter plates are separated. A push rod component mounted on the support seat moves above the filter plate to be removed, in cooperation with a displacement drive assembly. The push rod component drives the support seat to move, so that part of the filter plate is located within the support seat and clamped from both sides by an elastic support component. Subsequently, the displacement drive assembly drives the support seat to reciprocate, thereby causing the filter cake on the filter plate to fall off, achieving initial material removal. Simultaneously, a scraper component is provided at the bottom of the support seat. The scraper plate in the scraper component abuts against the filter cloth of the filter plate. With the cooperation of the push rod component, the scraper plate can move along the length of the filter plate, thereby scraping off the residual material on the filter plate. By shaking and scraping the filter plate, the filter press device can perform material removal, solving the problem that existing filter press devices are prone to failure to remove sticky materials, thus improving processing efficiency.

[0036] Reference Figures 1-4A filter press device for easy material removal includes a filter press body 1, which includes a machine body 11. Several filter plates 12 are movably arranged on the machine body 11 at intervals, forming a filter press chamber for extruding materials. The surface of the filter plates 12 is provided with filter holes and guide grooves for solid-liquid separation. Supports 111 are provided on both sides of the machine body 11 and displacement drive components 2 are installed. The displacement drive components 2 include supports 21, and two sets of supports 21 are provided and distributed opposite to each other on the two sets of supports 111. The supports 21 have cavities and are rotatably provided with lead screw components 22. One end of the lead screw component 22 extends to the outside of the support 21 and is connected to a first motor component 23. The first motor component 23 is a servo drive motor in the prior art. The lead screw component 22 and the first motor component 23 are connected by a coupling. When the first motor component 23 rotates, it drives the lead screw component 22 to rotate relative to each other.

[0037] A mounting base 24 is connected to the lead screw assembly 22. A support plate 241 is provided between two sets of mounting bases 24, and a push rod assembly 3 is installed thereon. The push rod assembly 3 can be any one of the pneumatic push rod, hydraulic push rod, or electric push rod in the prior art. The piston end of the push rod assembly 3 passes through the support plate 241 and is connected to a bearing seat 31. The bearing seat 31 has a cavity for accommodating the filter plate 12. The length and width of the cavity are both greater than the length and width of the filter plate 12. Elastic support members 4 are provided on both sides of the cavity. The elastic support members 4 are used to clamp the filter plate 12. The elastic support members 4 include elastic elements 41. The elastic elements 41 adopt the prior art. During the procedure, a pressure spring or extension spring is used. One end of the elastic element 41 is connected to the cavity, and the other end is connected to a clamping plate 42. The bottom of the clamping plate 42 is provided with an inclined part 421. The clamping plate 42 and the inclined part 421 are integrally formed and are both made of rubber. The two sets of clamping plates 42 form a trumpet-shaped structure with the cooperation of the inclined part 421. The width between the two sets of inclined parts 421 is greater than the width between the two sets of clamping plates 42. When the filter plate 12 is located in the cavity, the clamping plate 42 abuts against the filter plate 12. Through the cooperation of the screw component 22 and the first motor component 23, the push rod component 3 drives the filter plate 12 to move relative to each other.

[0038] Scraper components 5 are provided on both sides of the bottom of the support base 31. The two sets of scraper components 5 are symmetrically distributed and can simultaneously process the front and back sides of the filter plate 12 to improve the material removal efficiency. The scraper component 5 includes a scraper plate 51, which abuts against the two sides of the filter plate 12. Through the cooperation of the push rod component 3, the scraper component 5 moves relative to the filter plate 12 along its length.

[0039] Based on the above structure, after the filter press body 1 completes the filter pressing operation and moves several filter plates 12 to create a material discharge gap between adjacent filter plates 12, the lead screw component 22 in the displacement drive assembly 2 rotates in cooperation with the first motor component 23. This causes the placement seat 24 to move along the rotation direction of the lead screw component 22 via the support plate 241, thereby positioning the bearing seat 31 above the filter plate 12 to be discharged. Since the bearing seat 31 is connected to the push rod component 3, the extension and retraction of the push rod component 3 can drive the movement of the bearing seat 31, placing the filter plate 12 within the bearing seat 31. Furthermore, the elastic support components 4 on both sides of the bearing seat 31 allow the clamping plate 42 to clamp the filter plate 12 in cooperation with the elastic component 41. Subsequently, with the cooperation of the displacement drive component 2, the filter plate 12 can be moved repeatedly, and the filter cake is dislodged by the movement. At the same time, a scraper component 5 is provided at the bottom of the support seat 31. The extension and retraction of the push rod component 3 can make the scraper 51 scrape off the impurities remaining on the surface of the filter plate 12, ensuring the integrity of the dematerialization and cleaning the filter plate 12 during the scraping process. With the cooperation of the displacement drive component 2, the filter plate 12 can be simulated to move repeatedly during the dematerialization process. The scraper component 5 can also dematerialize and clean the filter plate 12 again. This solves the problem that the existing filter press body 1 requires manual operation when dematerializing materials with high viscosity, which leads to low processing efficiency and certain safety hazards.

[0040] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 4 and Figure 5 The scraper component 5 also includes a receiving plate 52, which is disposed at the bottom of the bearing seat 31. The receiving plate 52 has a groove 521, and a shaft 522 is rotatably disposed within the groove 521. A bearing seat is provided at the connection point between one end of the shaft 522 and the inner wall of the groove 521, thereby providing support and facilitating the rotation of the shaft 522. The scraper plate 51 has an opening and is fixed to the shaft 522. When the shaft 522 rotates, the scraper plate 51 rotates relative to it, causing... The scraper plate 51 and the receiving plate 52 are parallel or form an angle. When the scraper plate 51 is perpendicular to the receiving plate 52, the scraper plate 51 is in flat contact with the surface of the filter plate 12, which is suitable for large-area, low-resistance initial descraping and reduces filter cake damage. When an angle is formed, the edge of the scraper plate 51 generates local concentrated stress on the filter cake, which can effectively peel off stubbornly attached filter cake, especially for viscous materials or filter cakes with low moisture content, avoiding residue, and thus can be adjusted for different situations.

[0041] The scraper component 5 also includes a second motor component 53, which is a small servo drive motor in the prior art and is connected to an external power supply via a line. The second motor component 53 is located on one side of the receiving plate 52. One end of the shaft 522 is connected to the output end of the second motor component 53 via a coupling. With the cooperation of the second motor component 53, the shaft 522 can drive the scraper 51 to rotate, realizing motor drive to replace manual adjustment. The angle of the scraper 51 can be preset by the control system to ensure the consistency and repeatability of angle adjustment and avoid human operation errors. At the same time, the motor can provide stable torque to meet the resistance changes of different materials during scraping, avoiding angle loss of control due to excessive resistance during manual adjustment, and ensuring a smooth and reliable scraping process.

[0042] In one embodiment, reference is made to Figures 1-3 The support seat 31 is provided with flushing components 6 on both sides. The flushing components 6 include a support rod component 61. One end of the support rod component 61 is connected to the support seat 31, and the other end is connected to a pipe body 62. One end of the pipe body 62 is provided with a liquid inlet 621 connected to an external water source. The liquid inlet 621 is connected to an external water source through a pipeline.

[0043] The pipe body 62 is provided with several spaced nozzles 63. The nozzles 63 adopt high-pressure nozzles in the prior art. The output end of the nozzles 63 faces the filter plate 12. With the cooperation of the push rod component 3, the bearing seat 31 drives the flushing component 6 to move relative to each other. The multiple spaced nozzles 63 can cover the entire working area of ​​the filter plate 12. The high-pressure water flow washes away the filter cake debris and sticky substances remaining on the surface of the filter plate 12, prevents the filter holes from clogging, provides a clean surface for the next cycle of filter pressing, and ensures the cleanliness of the filter plate 12.

[0044] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 The support base 31 has a receiving groove, and part of the receiving plate 52 is movably disposed in the receiving groove. The support base 31 has a mounting hole 311, and the receiving plate 52 is provided with a limiting hole 523 that matches the mounting hole 311. Several limiting holes 523 are provided and are distributed at intervals along the length direction of the receiving plate 52. The setting of several limiting holes 523 can realize that when moving to different positions, they can be aligned with the mounting hole 311, thereby adjusting the initial working position of the scraper 51.

[0045] By moving the receiving plate 52 within the receiving groove, the mounting hole 311 is aligned with one of the sets of limiting holes 523. When the mounting hole 311 and the limiting hole 523 are aligned, a pin is connected to fix the receiving plate 52 onto the bearing seat 31. Adjusting the position of the receiving plate 52 within the receiving groove can change the lateral relative position between the scraper plate 51 and the filter plate 12, adapting to different specifications of filter plate 12. Furthermore, the pin-type connection facilitates quick disassembly of the receiving plate 52, allowing for the inspection or replacement of the scraper plate 51 without tools, reducing maintenance costs and improving equipment maintainability.

[0046] In one embodiment, reference is made to Figure 1 and Figure 2 The support rod component 61 includes a fixed rod 611 and a movable rod 612. The fixed rod 611 is mounted on the base 24, and the movable rod 612 is connected to the tube body 62. The fixed rod 611 has a placement groove, and part of the movable rod 612 is movable within the placement groove. Rubber, silicone, or spring sheets are embedded at the connection between the movable rod 612 and the fixed rod 611. When the movable rod extends or retracts, the elastic material is compressed and deformed, consuming energy through intermolecular friction. When the movable rod 612 is located within the placement groove, it can fit tightly against the inner wall of the placement groove, thus forming damping when the movable rod 612 moves. The movement of the movable rod 612 causes the tube body 62 to move closer to or further away from the fixed rod 611. The movement of the movable rod 612 adjusts the distance between the tube body 62 and the filter plate component 12, ensuring that the nozzle component 63 is at the optimal spray distance. This ensures both the water flow impact force and avoids water splashing due to excessive distance or insufficient flushing force due to excessive distance, achieving dynamic adjustment of the flushing distance and thus improving the flexibility of flushing.

[0047] In one embodiment, reference is made to Figure 2 The elastic support component 4 also includes a limiting sleeve 43, which is disposed on the side of the clamping plate 42 facing the bearing seat 31. The elastic element 41 is located inside the limiting sleeve 43. The limiting sleeve 43 constrains the compression direction of the elastic element 41, preventing the elastic element 41 from bending or shifting laterally when compressed, and ensuring that the elastic support force acts perpendicularly on the bearing seat 31, so that the scraper plate 51 or the flushing assembly 6 maintains uniform contact pressure with the surface of the filter plate 12.
