Description

Technical Field

[0001] This utility model belongs to the technical field of plate and frame filter presses, and in particular, it relates to a plate and frame filter press. Background Technology

[0002] After the filter press finishes its operation, a large amount of mud containing a small amount of moisture will adhere between the two filter plates. Therefore, it is necessary to clean these mud lumps in a timely manner. Currently, before cleaning the mud lumps between the filter plates, the two filter plates need to be separated. Most of the current methods for separating filter plates are through mechanical structures. However, existing mechanical structures can only separate the filter plates but cannot make the gaps between the separated filter plates the same. Therefore, it will directly affect the subsequent cleaning operation of the filter plates.

[0003] A search revealed a Chinese patent document (authorization announcement number CN220276371U) entitled "A Plate and Frame Filter Press for Easy Unloading," relating to the technical field of plate and frame filter presses. The press includes a support frame, with a sewage pump fixedly mounted on the top of the support frame. A top plate is fixedly mounted on the water delivery end of the sewage pump. A sliding guide rod is fixedly mounted on one side of the top plate, and a slip ring is movably mounted on the outer surface of the sliding guide rod. A filter pressing mechanism is fixedly mounted on one side of the slip ring. While the above-mentioned filter press unloading structure can improve the cleaning effect of the filter plates by driving a cleaning scraper to move up and down along the side wall of the filter plates, it cannot control the distance between the two filter plates when they are separated in actual use. This affects the cleaning scraper's ability to penetrate deeply between the two filter plates. Therefore, a plate and frame filter press is urgently needed to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a plate and frame filter press to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a plate and frame filter press, comprising an mounting plate for mounting a plate and frame filter device and filter plates for plate and frame filter pressing, wherein a rectangular hole is provided on the mounting plate, vertical plates are symmetrically fixedly installed in the rectangular hole, and two horizontal bars are fixedly installed between the two vertical plates, and multiple filter plates are slidably installed to the outside of the two horizontal bars;

[0006] The top surface of the mounting plate has two symmetrically formed slots. A slider is slidably installed inside the slot, and a screw is rotatably installed on the inner wall of the slot, with the screw thread passing through the slider.

[0007] Two sets of fixing plates are symmetrically fixedly installed on the top surface of the slider. A fixing rod is fixedly installed between each set of fixing plates. An inclined block and an L-shaped rod are respectively rotatably sleeved on the outer side of the two fixing rods. Torsion springs are installed between the side walls of the two inclined blocks and the L-shaped rods and the fixing plates.

[0008] Preferably, a U-shaped plate is fixedly installed on the top surface of the mounting plate, and a strip-shaped hole is opened horizontally on the top surface of the U-shaped plate.

[0009] Preferably, an electric slider is slidably installed inside the strip-shaped hole, and a hydraulic cylinder is fixedly installed at the bottom of the electric slider.

[0010] Preferably, the telescopic end of the hydraulic cylinder is fixedly mounted with a mounting bracket, and two cleaning rollers are symmetrically fixedly mounted on the bottom of the mounting bracket.

[0011] Preferably, two limiting strips are symmetrically fixedly installed on the side wall of the slider, and two limiting grooves are symmetrically opened on the inner wall of the strip groove.

[0012] Preferably, the two limiting strips symmetrically fixedly installed on the sidewall of the slider are slidably connected to the inside of the two limiting grooves opened on the inner wall of the strip groove.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This easy-to-unload plate and frame filter press benefits from the design of a strip groove, slider, screw, fixed plate, torsion spring, and tilting block. After filtration is completed, the starting screw drives the slider to move towards the extension plate installed on the side wall of the filter plate. When the tilting block contacts the extension plate, it will press down relative to the tilting block and twist the torsion spring. When the tilting block moves to the other side of the extension plate, the torsion spring will drive the tilting block back to its initial state and stop the slider from moving. At this time, the reverse starting screw pushes one extension plate and filter plate to one side of the rectangular hole through the tilting block. Then, the reverse starting screw drives the slider to move towards the extension plate on another filter plate again, thus automatically pulling the filter plate apart.

[0015] This easy-to-unload plate and frame filter press benefits from the design of the slider, screw, torsion spring, and L-shaped rod. When the slider and the inclined block separate a filter plate, when the bent part of the L-shaped rod on the slider contacts the extension plate on the previous filter plate, it will push the L-shaped rod to bend and start the screw in the opposite direction to drive the slider to move towards the unseparated filter plate again. When the L-shaped rod bends, the screw can be adjusted to rotate in the opposite direction, so that the distance between each separated filter plate is the same.

[0016] This easy-to-unload plate and frame filter press benefits from the design of hydraulic cylinders, mounting frames, and cleaning rollers. The hydraulic cylinders drive the mounting frames and cleaning rollers to move downwards along both sides of the filter plates and clean their side walls, thereby further improving the cleaning effect of the filter plates.

[0017] This easy-to-unload plate and frame filter press benefits from the design of U-shaped plates, strip holes, electric sliders, etc. The electric block drives the hydraulic cylinder to slide laterally along the strip holes, thereby adjusting the position of the two cleaning rollers, which facilitates the cleaning of multiple filter plates.

[0018] This easy-to-unload plate and frame filter press, compared with the prior art, can automatically separate the filter plates while controlling the distance between the two filter plates. Attached Figure Description

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0028] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0029] like Figures 1 to 4 The main structure of a plate and frame filter press shown is a mounting plate 2 for installing a plate and frame filter press device and a filter plate 6 for plate and frame filter press. A rectangular hole 3 is provided on the mounting plate 2. Vertical plates 4 are symmetrically fixedly installed in the rectangular hole 3. Two horizontal bars 5 are fixedly installed between the two vertical plates 4. Multiple filter plates 6 are slidably installed to the outside of the two horizontal bars 5. An extension plate is fixedly installed on one side of each of the two filter plates 6.

[0030] The top surface of the mounting plate 2 has two symmetrically formed grooves 7. A slider 8 is slidably installed inside the groove 7, and a screw 9 is rotatably installed on the inner wall of the groove 7, with the screw 9 threaded through the slider 8.

[0031] Two sets of fixing plates 16 are symmetrically fixedly installed on the top surface of slider 8. A fixing rod 17 is fixedly installed between each set of fixing plates 16. An inclined block 19 and an L-shaped rod 20 are respectively rotatably sleeved on the outer side of the two fixing rods 17. A torsion spring 18 is installed between the side wall of the two inclined blocks 19 and the L-shaped rod 20 and the fixing plate 16. Thanks to the arrangement of the strip groove 7, slider 8, screw 9, fixing plate 16, torsion spring 18 and inclined block 19, after the filter press is completed, the slider 8 is moved towards the extension plate installed on the side wall of the filter plate 6 by starting the screw 9. When the tilting block 19 contacts the extension plate, it will be pressed down relative to the tilting block 19 and twist the torsion spring 18. When the tilting block 19 moves to the other side of the extension plate, the torsion spring 18 will drive the tilting block 19 back to the initial state and stop the slider 8 from moving. At this time, the reverse starting screw 9 pushes an extension plate and filter plate 6 to one side of the rectangular hole 3 through the tilting block 19. Then, the reverse starting screw 9 drives the slider 8 to move to the extension plate on another filter plate 6 again, so as to automatically pull the filter plate 6 apart.

[0032] When the tilting block 19 and the L-shaped rod 20 are pushed and tilted relative to each other by the extension plate, the rotation direction of the screw 9 will be adjusted, thereby effectively making the distance between the multiple filter plates 6 that are pulled apart the same.

[0033] A U-shaped plate 10 is fixedly installed on the top surface of the mounting plate 2, and a strip-shaped hole 11 is opened laterally on the top surface of the U-shaped plate 10. An electric slider 12 is slidably installed in the strip-shaped hole 11, and a hydraulic cylinder 13 is fixedly installed at the bottom of the electric slider 12. A mounting frame 14 is fixedly installed at the telescopic end of the hydraulic cylinder 13. Two cleaning rollers 15 are symmetrically fixedly installed at the bottom of the mounting frame 14. Thanks to the structure of the hydraulic cylinder 13, the mounting frame 14, and the cleaning rollers 15, the hydraulic cylinder 13 drives the mounting frame 14 and the cleaning rollers 15 to move downward along both sides of the filter plate 6 and clean its side walls, thereby further improving the cleaning effect of the filter plate 6. Thanks to the structure of the U-shaped plate 10, the strip-shaped hole 11, and the electric slider 12, the electric slider 12 drives the hydraulic cylinder 13 to slide laterally along the strip-shaped hole 11, thereby adjusting the position of the two cleaning rollers 15, which facilitates the cleaning of multiple filter plates 6.

[0034] Two limiting strips 21 are symmetrically fixedly installed on the side wall of the slider 8. Two limiting grooves are symmetrically opened on the inner wall of the strip groove 7. The two limiting strips 21 symmetrically fixedly installed on the side wall of the slider 8 are slidably connected to the inside of the two limiting grooves opened on the inner wall of the strip groove 7. The limiting strips 21 can effectively limit the sliding direction of the slider 8 and further improve the stability of the slider 8 when sliding.

[0035] Working principle

[0036] This easy-to-unload plate and frame filter press, when multiple filter plates 6 need cleaning, starts the screw 9 to move the slider 8 towards the extension plate fixed to the side wall of one of the filter plates 6. When the inclined block 19 on the slider 8 contacts the extension plate, the extension plate pushes the inclined block 19 downward and twists the torsion spring 18. When the inclined block 19 is misaligned with the extension plate, the torsion spring 18 will drive the inclined block 19 upward to return to its initial state. At this time, the screw 9 is started in reverse, which moves the slider 8 and pushes the extension plate and filter plate 6 towards one side of the rectangular hole 3 through the inclined block 19. When the slider 8 moves to one side of the strip groove 7... When the L-shaped rod 20 is in contact with the extension plate, the L-shaped rod 20 is tilted downwards and offset from the extension plate because its end is arc-shaped. This causes the tilting block 19 on the slider 8 to move to the other side of the next extension plate to be separated. The tilting block 19 then presses down, causing the screw 9 to rotate in the opposite direction and separating the extension plate and the filter plate 6. When the L-shaped rod 20 contacts the extension plate on the previous filter plate 6, it will push the L-shaped rod 20 downwards and cause the screw 9 to rotate in the opposite direction again. Repeating this operation can effectively separate multiple filter plates 6 and make the distance between multiple filter plates 6 the same.
