[0035] The present invention will be described more specifically by way of example in the following paragraphs with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0036] The filter plate and filter plate assembly of this utility model will be described below with reference to Figures 1 to 6 in the specification.

[0037] In one embodiment, as shown in Figures 1, 2, 3 and 4, the filter plate of this application includes a plate body 1 and a reinforcing plate frame 2.

[0038] As shown in Figure 4, the reinforcing plate frame 2 includes an annular frame 21 and a plurality of reinforcing ribs 22 located on one side of the annular frame 21.

[0039] As shown in Figures 2 and 3, the plate 1 has a water-facing surface and a water-repellent surface. A circumferential annular groove 11 adjacent to the water-facing surface is provided on the circumferential side of the plate 1. The annular frame 21 is disposed in the circumferential annular groove 11. The water-facing surface is provided with a plurality of reinforcing grooves 12 corresponding one-to-one with the reinforcing ribs 22. The reinforcing ribs 22 are disposed in the reinforcing grooves 12.

[0040] This application significantly improves the structural strength of the filter plate by incorporating a circumferential groove 11 and a reinforcing groove 12, ensuring a tight fit between the annular frame 21 and the reinforcing ribs 22 and the plate body 1. Specifically, the annular frame 21 is embedded in the circumferential groove 11, and the reinforcing ribs 22 are embedded in the reinforcing groove 12. This design effectively distributes the stress, reducing the risk of the filter plate breaking under stress. Compared with existing technologies, this solution not only enhances the impact resistance of the filter plate but also extends its service life, solving the technical problem of easy breakage of filter plates in wastewater treatment equipment.

[0041] The plate body 1 is provided with a microporous structure with filtration function, such as a microporous foam ceramic filter plate. The circumferential annular groove 11 and reinforcing groove 12 on the plate body 1 can be processed by mechanical equipment.

[0042] In some embodiments, the plurality of the reinforcing ribs 22 form a mesh structure.

[0043] The reinforcing ribs 22 can be made of metal or high-strength plastic to further improve the impact resistance of the filter plate. Specifically, the metal material can be stainless steel or aluminum alloy, while the high-strength plastic can be polycarbonate or nylon.

[0044] As a preferred embodiment, the cross-sectional shape of the reinforcing rib 22 can be rectangular, circular, or trapezoidal to optimize its stress distribution. For example, a rectangular cross-section reinforcing rib 22 has better bending resistance when subjected to impact forces, while a circular cross-section reinforcing rib 22 is easier to process and install. Furthermore, the mesh-structured reinforcing ribs 22 can be connected by welding or adhesive to ensure their stability and durability.

[0045] In other embodiments, it can also be configured as T-shaped or L-shaped to increase its contact area with plate 1, thereby enhancing structural stability.

[0046] Specifically, the mesh structure of the reinforcing ribs 22 can effectively disperse and absorb external impact forces, thereby improving the overall strength and impact resistance of the filter plate. The mesh structure of the reinforcing ribs 22 forms a stable support network through interconnection, making the filter plate less prone to breakage under external forces, thus enhancing its durability and service life.

[0047] Furthermore, in one embodiment, the reinforcing frame 2 is fixedly connected to the plate body 1 by adhesive 13.

[0048] Adhesive 13 acts as an adhesive, effectively and firmly fixing the reinforcing frame 2 into the circumferential groove 11 of the plate body 1. The choice of adhesive 13 can be adjusted according to specific application scenarios. For example, epoxy resin adhesive, polyurethane adhesive, or silicone adhesive can be used as hardening adhesives. These adhesives 13 have different bonding strengths and environmental resistance properties, and can adapt to different working conditions. In addition, the application method of adhesive 13 can also be adjusted as needed, such as uniform application, dot application, or line application, to ensure optimal bonding effect.

[0049] By using glue 13 for fixing, the connection strength between the annular frame 21 and the plate 1 is significantly enhanced, thus solving the technical problem of weak connection between the annular frame 21 and the plate 1. The use of glue 13 not only improves the overall structural stability of the filter plate, but also enhances its impact resistance, making the filter plate less prone to cracking under stress.

[0050] As shown in Figures 5 and 6, this application also provides a filter plate assembly, including a plate assembly frame 3 and a plurality of filter plates as described in any of the above technical solutions located in the plate assembly frame 3, wherein the plate assembly frame 3 and the plurality of filter plates form a filter cavity 31.

[0051] Specifically, the design of the plate frame 3 allows multiple filter plates to be arranged closely, increasing the filtration area and thus improving wastewater treatment efficiency. The design of the filter chamber 31 ensures that wastewater passes evenly through multiple filter plates, guaranteeing consistent filtration performance.

[0052] Furthermore, in some embodiments, the plate frame 3 has a plurality of mounting positions 32 that are adapted to and correspond one-to-one with the filter plate, and the filter plate is fixed in the mounting positions 32.

[0053] The design of the mounting frame 32 allows each filter plate to be precisely installed in its predetermined position, ensuring a perfect fit between the filter plate and the mounting frame 32. The filter plate can be secured in the mounting frame 32 in various ways, such as by adhesive strips, clips, or other fasteners 36.

[0054] For example, the plate assembly frame 3 has four mounting positions 32. Two mounting positions 32 and their corresponding filter plates form a group. The bottoms of two mounting positions 32 in the same group are connected by a bottom wall 33 to form a filter chamber 31. In this embodiment, the plate assembly frame 3 has two filter chambers 31, which are connected by a connecting plate 34. In other embodiments, two or six mounting positions can be provided to form one or three filter chambers respectively.

[0055] Preferably, in some embodiments, as shown in FIG1, the filter plate is circumferentially arranged with elastic rubber strips 4, and as shown in FIG5, the mounting frame 32 has an annular mounting groove, the annular mounting groove including a horizontal side and a vertical side, the included angle between the vertical side and the horizontal side being greater than 75° and less than 90°, so as to snap the filter plate with elastic rubber strips 4 into the mounting frame 32.

[0056] Specifically, the elastic strip 4 can be made of elastic materials, such as rubber or silicone, to ensure that it can be compressed during installation and return to its original shape after being in place. The included angle between the horizontal and vertical sides of the annular mounting groove is designed to be greater than 75° and less than 90°. This angle design allows the strip to be effectively compressed during the pressing process and to fit tightly into the mounting groove through elastic restoring force after being in place, thereby achieving a stable fixing effect.

[0057] The technical problem of unstable fixation of the filter plate in the mounting frame 32 is solved by the cooperation of the rubber strip and the annular mounting groove. During the installation process, the rubber strip is compressed and then returns to its original shape, so that the filter plate can be firmly locked into the mounting frame 32, avoiding loosening or falling off due to vibration or impact during operation, and eliminating the need for additional fasteners 36, thus reducing costs.

[0058] Furthermore, in some embodiments, as shown in FIG1, the cross-section of the elastic strip 4 is L-shaped, the horizontal section of the elastic strip 4 is attached to the circumferential side of the filter plate, and the vertical section of the elastic strip 4 is attached to the water-facing surface of the filter plate.

[0059] The L-shaped design of the elastic adhesive strip 4, with its horizontal and vertical sections respectively attached to the circumferential side and water-facing side of the filter plate, increases the contact area between the strip and the filter plate, thereby improving the adhesion and sealing between them. This design makes the filter plate more securely fixed in the mounting frame 32, providing better sealing and reducing the possibility of loosening or falling off during use. It effectively solves the technical problems of insecure filter plate fixing and poor sealing.

[0060] In addition, the L-shaped design of the rubber strip can be adjusted to accommodate filter plates of different sizes by adjusting the length ratio of the horizontal and vertical sections, further improving its versatility and applicability.

[0061] In some other embodiments, as shown in FIG6, the filter plate is fixed in the mounting frame 32 by a fastener 36.

[0062] The fastener 36 can be a snap fastener, bolt, clip, or other device capable of achieving a fixing function. As a preferred embodiment, the snap fastener design allows the filter plate to be quickly and securely installed in the frame, improving the stability and service life of the filter plate. Specifically, the snap fastener can achieve a tight fit with the mounting frame 32 through elastic deformation, thereby ensuring the filter plate is firmly fixed in the mounting frame 32.

[0063] In some embodiments, the plate frame 3 has a central symmetry plane 35 extending in a vertical direction, and two filter plates are symmetrically arranged on both sides of the central symmetry plane 35. The two filter plates have a set inclination angle with the central symmetry plane 35 so that impurity particles are detached from the filter plates due to their own weight.

[0064] Specifically, the tilt design allows impurity particles to slide off the filter plate more easily under the influence of gravity, thereby improving filtration efficiency and reducing the risk of clogging.

[0065] In a preferred embodiment, the set tilt angle is greater than or equal to 5° and less than or equal to 45°. For example, the set tilt angle can be 5°, 10°, 20°, 30°, 40°, or 45°.

[0066] The set tilt angle can be further optimized to between 10° and 30° to ensure that impurity particles can be effectively removed. In addition, the design of the central symmetry plane 35 allows the two filter plates to be arranged symmetrically. This symmetry helps to evenly distribute the filtration pressure and avoid excessive local stress.

[0067] Taking the plate frame 3 in the figure as an example, it has two central symmetry planes 35, and two mounting frames 32 and corresponding filter plates are symmetrically arranged on both sides of each central symmetry plane 35.

[0068] This embodiment, through its tilt angle design, allows impurity particles to more easily and automatically slide off the filter plate under gravity, giving the filter a self-cleaning capability. This improves filtration efficiency and reduces the risk of clogging, eliminating the need for backflushing to clean the filter plate and extending its lifespan. Furthermore, the 35° central symmetry plane design ensures the two filter plates are symmetrically arranged. This symmetry helps to evenly distribute filtration pressure, preventing excessive localized stress and further enhancing the stability and lifespan of the filter plates.

[0069] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
