[0027] As Figure 1 and Figure 4 shown, in the present embodiment, the filter plate structure comprises a plate body 10 and an elastic support structure 20. The elastic support structure 20 extends along the width direction of the plate body 10 and is located on the bottom side wall of the plate body 10.

[0028] The technical scheme of the present embodiment is applied, the elastic support structure is arranged on the bottom side wall of the plate body, and the elastic support structure extends along the width direction of the plate body. Through the above arrangement, the elastic support structure can support the filter bag, and can prevent the bottom of the filter bag from protruding downward from the plate body, so as to prevent the part that cannot be filtered. And when filtering, the elastic support structure can be deformed, so as not to affect the movement of the filter plate. Therefore, the technical scheme of the present embodiment effectively solves the problem that the bottom of the filter bag is easy to protrude downward from the filter plate in the related art, which affects the filtering effect.

[0029] Specifically, the technical scheme of the present embodiment utilizes the elastic support structure 20 to provide bottom support for the filter bag 1 during the filtering process, avoids the collapse of the filter cake during the formation process, ensures the uniformity of the filter cake, and thus improves the filtering efficiency and the quality of the filter cake.

[0030] As Figure 1 , Figure 2 and Figure 4As shown, in this embodiment, the elastic support structure 20 includes a first elastic support member 21 and a second elastic support member 22, which are respectively disposed on both sides of the plate body 10. By providing the first elastic support member 21 and the second elastic support member 22 on both sides of the plate body 10, the deformation of the filter bag 1 during the filtration process can be better accommodated, providing a more uniform support force, avoiding the problem of uneven loading during filter cake formation, and ensuring that the thickness and quality of the filter cake are consistent. Furthermore, the first elastic support member 21 and the second elastic support member 22 can each correspond to different filter bags 1, thereby resulting in higher filtration efficiency.

[0031] like Figure 1 , Figure 2 as well as Figure 4 As shown, in this embodiment, the top of the first elastic support 21 is provided with a first guide slope 211. The distance between the first guide slope 211 and the plate body 10 gradually increases from the top to the bottom of the plate body 10. Similarly, the top of the second elastic support 22 is provided with a second guide slope 221. The distance between the second guide slope 221 and the plate body 10 gradually increases from the top to the bottom of the plate body 10. The design principle of the first guide slope 211 and the second guide slope 221 is to utilize the guiding effect of the slopes to facilitate water flow during the pressure filtration process, preventing water from pooling and failing to drain. Simultaneously, during the pressure filtration process, the slopes can guide the filtrate to distribute evenly, improving filtration efficiency.

[0032] like Figures 1 to 4 As shown, in this embodiment, the elastic support structure 20 is connected to the plate body 10 via a first connecting structure 30. The first connecting structure 30 includes a connecting groove 31 and a connecting block 32. The connecting block 32 can be inserted into the connecting groove 31. One of the connecting groove 31 and the connecting block 32 is disposed on the elastic support structure 20, and the other of the connecting groove 31 and the connecting block 32 is disposed on the plate body 10. The first connecting structure 30 achieves a firm connection between the elastic support structure 20 and the plate body 10 through the cooperation of the connecting groove 31 and the connecting block 32, while facilitating disassembly and assembly and simplifying the maintenance process. This improves the connection strength and stability between the plate body 10 and the elastic support structure 20, reduces maintenance costs, and enhances the maintainability of the equipment.

[0033] Specifically, both the first elastic support member 21 and the second elastic support member 22 are connected to the plate body 10 through the first connecting structure 30.

[0034] like Figures 1 to 4 As shown, in this embodiment, the connecting groove 31 is a dovetail groove. The design of the dovetail groove utilizes its unique shape to provide stronger connection strength and stability, preventing the elastic support structure 20 from loosening or falling off during high-pressure filtration.

[0035] In an embodiment not shown in the figures, the connecting groove 31 is a rectangular groove, a triangular groove or a groove of other shape. The shape of the connecting block 32 is adapted to the shape of the connecting groove.

[0036] As shown in Figure 1 , Figure 2 and Figure 4 , in the present embodiment, the material of the elastic support structure 20 is rubber or silicone. The rubber material or the silicone material has good elasticity and wear resistance, ensuring that the elastic support structure 20 can provide stable support force during the high-pressure filtration process, and has a long service life.

[0037] As shown in Figure 1 and Figure 4 , in the present embodiment, the filter plate structure further comprises a second connecting structure 40 provided on the top of the plate body 10 and used to fix the filter bag 1, the second connecting structure 40 comprises a base frame 41 extending along the width direction of the plate body 10 and a connecting beam 42 provided on the base frame 41, the base frame 41 is provided on the top of the plate body 10, and a plurality of connecting protrusions 421 are provided on the connecting beam 42. The second connecting structure 40 provides top fixation for the filter bag 1 through the combination of the base frame 41 and the connecting beam 42, ensuring the stability and sealing performance of the filter bag 1 during the filter pressing process, and avoiding leakage of the filtrate. The second connecting structure 40 is detachably provided on the plate body 10, and drives the filter bag 1 to be detachable with the plate body 10.

[0038] Specifically, the top of the filter bag 1 is connected to the connecting protrusion 421.

[0039] As shown in Figure 1 and Figure 4 , in the present embodiment, the connecting beam 42 comprises a first beam body 422 and a second beam body 423 capable of moving closer to or away from each other, the first beam body 422 and the second beam body 423 are arranged on the base frame 41 in a spaced manner along the thickness direction of the plate body 10, and the second connecting structure 40 further comprises an elastic connecting piece 43 connected between the first beam body 422 and the second beam body 423. The elastic connecting piece 43 uses its elastic property to provide adjustable top fixation for the filter bag 1, adapts to the size change of the filter bag 1 in different working states, and ensures the sealing performance and stability of the filter bag 1 during the filter pressing process. Moreover, the elastic connecting piece 43 can drive the first beam body 422 and the second beam body 423 to reset, that is, when the first beam body 422 and the second beam body 423 move away from each other, the elastic connecting piece 43 can drive the first beam body 422 and the second beam body 423 to move closer to each other.

[0040] As shown in Figure 1 and Figure 4As shown, in the embodiment, the second connecting structure 40 further comprises a guide structure 44, which is arranged between the first beam body 422 and the second beam body 423. The guide structure 44 is designed to make the movement of the first beam body 422 and the second beam body 423 more stable, avoiding the dislocation.

[0041] According to another aspect of the present application, there is provided a filter assembly, such as Figure 5 As shown, the filter assembly of the embodiment comprises the filter bag 1 and the filter plate structure, which is the filter plate structure described above. The elastic support structure 20 in the filter plate structure can effectively support the filter bag 1, avoiding the deformation of the filter bag 1 from the plate body 10, thereby ensuring the effect of filter pressing. Therefore, the filter assembly with the filter plate structure described above also has the advantages described above.

[0042] Meanwhile, the filter assembly realizes efficient filtration and uniform formation of filter cake through the combination of the filter bag and the optimized filter plate structure, while reducing the weight and floor area of the equipment, improving the processing capacity and reducing the cost of spare parts.

[0043] In the embodiment, a flow-through structure is arranged between any two adjacent filter bags, the flow-through structure has a plurality of flow-through channels, and at least part of the plurality of flow-through channels are in communication with each other. Each flow-through channel has a first port and a second port, and any surface of the flow-through structure has at least one first port. When the filter assembly is pressed to filter water, the water in the filter bag 1 can enter the plurality of flow-through channels.

[0044] Compared with the traditional single-plane steel wire mesh, the technical solution of the embodiment uses thicker metal pieces and different weaving methods. The metal pieces are processed with fold lines in the thickness direction of the flow-through structure, and from the side, it can be observed that due to the bending of the metal pieces, the flow-through structure has more pores in the thickness direction. In the filter pressing process, complete discharge channels are provided for the filtrate, avoiding the blockage of the filter bag 1 in the gap of the flow-through structure, thereby improving the drainage speed. Moreover, when a large pressure is withstood, the thickness direction of the flow-through structure needs to have a certain space stability, that is, whether in the feeding stage or the pressing stage, the drainage path in the direction of the filter bag 1 needs to exist all the time. Through the flow-through structure in this form, in the feeding and filter pressing process, the filtrate is first separated from the filter bag 1 into the flow-through structure, and then is discharged from the filter bag 1 in the direction of the flow-through structure.

[0045] The flow-through structure comprises a plurality of first metal pieces, the plurality of first metal pieces are arranged at intervals along a first preset axis direction, each first metal piece has a plurality of first bending portions, part of the plurality of first bending portions protrude towards the plate body 10, and the rest of the plurality of first bending portions protrude towards the filter bag 1. The first metal piece has good structural strength, and the plurality of first bending portions can further improve the structural strength of the flow-through structure, thereby avoiding being extruded and deformed. Meanwhile, part of the plurality of first bending portions protrude towards the plate body 10, so that the first bending portion can realize support, that is, each first bending portion is clamped between the filter bag 1 and the plate body 10, thereby enabling the filter bag 1 and the plate body 10 to have sufficient space, so that water can be more easily discharged.

[0046] It should be noted that the first bending portion and the plate body 10 and the first bending portion and the filter bag 1 form a first channel, two adjacent first metal pieces form a second channel, and the plate body 10 and the filter bag 1 form a third channel.

[0047] The end of each first bending portion is a circular arc transition portion. The above arrangement can prevent scratching the filter bag 1.

[0048] The flow-through structure further comprises a plurality of second metal pieces, the plurality of second metal pieces are arranged at intervals along a second preset axis direction, and any first metal piece is connected to at least part of the plurality of second metal pieces. The arrangement of the second metal piece can further improve the structural strength of the flow-through structure.

[0049] Each second metal piece has a plurality of second bending portions, part of the plurality of second bending portions protrude towards the plate body 10, and the rest of the plurality of second bending portions protrude towards the filter bag 1. The above arrangement can make the contact area of the flow-through structure with the filter bag 1 larger, so as to not only ensure the structural strength of the flow-through structure, but also avoid damaging the filter bag 1.
