[0048] This utility model provides a filter press device, which includes a front cover plate 10, a rear cover plate 20, a filter screen 70, and a pressing assembly 30. The front cover plate 10 has a feed hole 13; the rear cover plate 20 has a discharge hole 22 for communicating with an external material collection device; the filter screen 70 is disposed between the front cover plate 10 and the rear cover plate 20; one end of the pressing assembly 30 is connected to the front cover plate 10, and the other end is connected to the rear cover plate 20, so that the front cover plate 10 and the rear cover plate 20 press the filter screen 70 tightly.

[0049] Please refer to Figure 1 and Figure 2 The feed port 13 is used to connect one end of a pipeline, and the other end of the pipeline is connected to the discharge port of an external material cylinder. The pipeline can be a flexible hose or a custom-made rigid pipe, etc. The discharge port 22 is used to connect to external material collection equipment or to dock with the feeding end of the next process.

[0050] To ensure that the feed hole 13 can be connected to the pipeline, the feed hole 13 includes a connecting section 11 and a feed section 12 connected to the connecting section 11. The connecting section 11 is cylindrical to adapt to the shape of the pipeline and ensure that the pipeline can be stably clamped in the feed hole 13.

[0051] It is understandable that the pressure inside the feed cylinder is relatively high. When the feed cylinder discharges, the slurry is forced from the connecting section 11 into the feeding section 12.

[0052] After the slurry enters the feed section 12 from the connecting section 11, it flows along the side wall of the feed section 12 towards the filter screen 70. The feed section 12 is funnel-shaped, and its inner diameter gradually increases along the side away from the connecting section 11 to increase the contact area between the slurry and the filter screen 70 and improve the filtration efficiency.

[0053] Correspondingly, the rear cover plate 20, like the front cover plate 10, has a discharge section 21. The discharge section 21 is symmetrically arranged with the infeed section 12, meaning that the discharge end gradually narrows towards the discharge hole 22. The discharge hole 22 is cylindrical in shape to facilitate connection with the pipeline of the material collection equipment.

[0054] The filter screen 70 is placed between the front cover plate 10 and the rear cover plate 20. During assembly, the front cover plate 10 and the rear cover plate 20 are pressed together by the crimping assembly 30, thereby pressing and fixing the filter screen 70 in the middle. When the filter screen 70 needs to be replaced, the operator only needs to remove the crimping assembly 30, loosen the front cover plate 10 and the rear cover plate 20 to release the filter screen 70, and then remove the filter screen 70.

[0055] This utility model's technical solution employs a method where the front cover plate 10 and the rear cover plate 20 cover and press against the filter screen 70, with the pressing assembly 30 achieving a pressing connection between the front cover plate 10 and the rear cover plate 20. During disassembly and assembly, only the pressing assembly 30 needs to be removed to replace the filter screen 70. The operation is simple, allowing a single person to complete the filter screen 70 replacement, improving disassembly and assembly efficiency and achieving user-friendly production.

[0056] Specifically, the front cover plate 10 has a first flange edge 15 on its edge, and the rear cover plate 20 has a second flange edge 23 on its edge.

[0057] The crimping assembly 30 includes a pin 31, a connecting ring 32, and a locking structure 33. One end of the pin 31 abuts against the second flange edge 23, and the other end passes through the second flange edge 23 and the first flange edge 15 respectively. The connecting ring 32 is disposed on the end of the pin 31 away from the second flange edge 23. The locking structure is connected to the connecting ring 32 to lock the pin 31 onto the first flange edge 15 and the second flange edge 23.

[0058] Both the first flange edge 15 and the second flange edge 23 are provided with perforations, and the positions of the two perforations correspond when the front cover plate 10 and the rear cover plate 20 are closed.

[0059] The pin 31 can be inserted through two through holes into the first flange edge 15 and the second flange edge 23. The end dimension of the pin 31 is larger than the diameter of the through hole, so that after the pin 31 passes through the two flange edges, the end will abut against one of the flange edges. In this embodiment, it abuts against the second flange edge 23 as an example.

[0060] The other end of the pin 31 passes through the first flange edge 15 and is connected to the connecting ring 32.

[0061] It is understood that the connecting ring 32 and the pin 31 can be integrally formed, as long as the size of the connecting ring 32 is less than or equal to the diameter of the hole.

[0062] The locking structure 33 is connected to the connecting ring 32, locking the pin 31 onto the two flange edges. In this embodiment, the locking structure 33 abuts against the first flange edge 15 when locked, thereby ensuring that the two flange edges are properly fitted.

[0063] Furthermore, a sealing ring can be installed between the first flange edge 15 and the second flange edge 23 to prevent slurry leakage. Alternatively, a sealing ring can be installed at the connection point between the feed section 12 and the discharge section 21 for sealing.

[0064] Specifically, the locking structure 33 includes two fixing plates 331 and a locking screw 332. The two fixing plates 331 are arranged opposite each other on the side of the first flange edge 15 away from the second flange edge 23. The connecting ring 32 is located between the two fixing plates 331. The locking screw 332 passes through the connecting ring 32, and both ends of the locking screw 332 are respectively connected to the two fixing plates 331.

[0065] The fixing plate 331 is perpendicularly connected to the first flange edge 15. After the locking screw 332 passes through the annular hole of the connecting ring 32, both ends are fixed to the two fixing plates 331 by nuts to fix the connecting ring 32 and prevent the pin 31 from shaking.

[0066] To facilitate the handling of the pin 31, a handle 311 is provided at the end opposite to the connecting ring 32.

[0067] To improve the sealing between the front cover plate 10 and the rear cover plate 20, a plurality of pressing components 30 may be provided, and the plurality of pressing components 30 are spaced apart along the edges of the front cover plate 10 and the rear cover plate 20.

[0068] Further, please refer to Figure 3 The filter press further includes a support 40 and a connecting plate 50. The connecting plate 50 is disposed on the support 40, and the front cover plate 10 is connected to the connecting plate 50.

[0069] To improve the flexibility of the filter press device of this utility model, the front cover plate 10 and the rear cover plate 20 are fixed on the bracket 40.

[0070] The feed hole 13 is connected to the feed cylinder via a pipeline, so that when replacing the filter screen 70, it is not necessary to disassemble the feed cylinder. The front cover plate 10 and the rear cover plate 20 can be opened simply by using the pressing assembly 30.

[0071] The connecting plate 50 is installed on the top of the bracket 40. The front cover plate 10 has a flange 14 at the feed port position. The flange 14 can be fixed to the connecting plate 50 by screws.

[0072] To improve the connection strength of the connecting plate 50, the connecting plate 50 includes two connecting arms 51, which are arranged in an L-shape. One connecting arm 51 is connected to the bracket 40, and the other connecting arm 51 is connected to the front cover plate 10. A reinforcing rib 52 is provided between the two connecting arms 51.

[0073] The bracket 40 includes a support base 41 and a pulley 42. The connecting plate 50 is disposed on the top of the support base 41, and the pulley 42 is disposed on the bottom of the support base 41.

[0074] The support base 41 is rectangular and is provided with pulleys 42 on all four sides. The two front pulleys 42 can be omnidirectional wheels to facilitate turning when moving the support base 41, and the two rear pulleys 42 can be directional wheels.

[0075] The support base 41 adopts an aluminum alloy bracket 40 to ensure structural strength and stability in use.

[0076] Furthermore, the limiting component 60 includes a first limiting plate 61, a second limiting plate 62, and a limiting screw 63. The first limiting plate 61 is disposed on the front cover plate 10; the second limiting plate 62 is disposed on the rear cover plate 20, and the first limiting plate 61 and the second limiting plate 62 are offset from each other. When the front cover plate 10 is closed on the rear cover plate 20, the first limiting plate 61 and the second limiting plate overlap, and the limiting screw 63 passes through the first limiting plate 61 and the second limiting plate 62.

[0077] To ensure that the front cover plate 10 and the rear cover plate 20 are properly closed, a first limiting plate 61 and a second limiting plate 62 are respectively provided on their edges. When the front cover plate 10 and the rear cover plate 20 are properly closed, the limiting holes on the two limiting plates are in corresponding positions.

[0078] The limiting screw 63 is passed through the two limiting plates and locked to prevent the front cover plate 10 and the rear cover plate 20 from shifting during use, thereby preventing slurry leakage and avoiding safety hazards.

[0079] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
