Description

Technical Field

[0001] This utility model relates to the technical field of filter press accessories, specifically to an ultra-high pressure chamber filter plate with a metal reinforcing frame. Background Technology

[0002] The core function of a chamber filter plate is to work with adjacent filter plates to form a sealed filter chamber, while simultaneously withstanding the working pressure during filtration to ensure the orderly progress of solid-liquid separation. As a core functional component of a filter press, the performance of the chamber filter plate directly determines the working efficiency and stability of the filter press.

[0003] However, current traditional chamber filter plates are mostly made of polypropylene blends, manufactured through extrusion and compression molding, or directly using injection molding. When used in conjunction with ultra-high pressure filter presses, the extremely strong compressive force generated during operation causes significant deformation problems in the polypropylene filter plates, such as thinning and misalignment, leading to filter plate failure and malfunction. Furthermore, the immense pressure within the filter chamber due to ultra-high pressure conditions can easily cause the filter plates to burst, damaging the plates themselves, disrupting normal production, and posing safety hazards and threats to the working environment. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide an ultra-high pressure chamber filter plate with a metal reinforcing frame, thereby solving the problem that existing chamber filter plates lack sufficient strength and cannot be well applied in ultra-high pressure filter presses.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides an ultra-high pressure chamber filter plate with a metal reinforcing frame, comprising: a plate body, wherein a reinforcing space is provided around the plate body, and a first frame and a second frame are provided within the reinforcing space, and the first frame, the second frame, and the plate body are respectively locked together by a first locking part and a second locking part; wherein, the second frame is engaged on the plate body, the first frame covers the second frame, and the first frame has a first gap from the end face of the plate body.

[0006] Optionally, the plate has a first direction line, a second direction line and a third direction line, and the plate has a first notch, a second notch and a third notch respectively formed along the first direction line, the second direction line and the third direction line.

[0007] Optionally, the second frame has a second frame plate and a second frame piece fixed to the second frame plate and arranged in parallel.

[0008] Optionally, the second frame plate is parallel to the third direction line, the second frame piece is parallel to the second direction line, and is inserted into the second notch from the second direction line.

[0009] Optionally, the first frame has a first frame plate and a first frame piece fixed to the first frame plate and arranged in parallel.

[0010] Optionally, the first frame piece and the first frame plate together form a covering notch, the covering notch including a first notch and a second notch, the second frame piece being disposed within the first notch, and the second frame plate being disposed within the second notch.

[0011] Optionally, the first frame plate has a plurality of arrayed first grooves, and the first locking part is disposed in the first groove, and the first locking part is disposed parallel to the first direction line.

[0012] Optionally, the first frame piece has a plurality of arrayed second grooves, and the second locking part is disposed in the second groove, and the second locking part is disposed parallel to the second direction line.

[0013] Optionally, the plate is formed by molding or injection molding, and the first notch, the second notch and the third notch are all formed by cutting and grinding.

[0014] Optionally, both the first frame and the second frame are integrally formed.

[0015] The beneficial effects of this utility model are as follows: This utility model features a reinforcing space around the perimeter of the plate. The structural design of this reinforcing space precisely adapts to the installation requirements of the first and second frames, providing a stable foundation for their placement and positioning. Simultaneously, a first and second frame made of metal are installed within the reinforcing space, and the two frames are securely locked within the reinforcing space by a first and second locking part. This effectively compensates for the insufficient strength of traditional polypropylene filter plate frames, significantly improving the overall rigidity and pressure-bearing capacity of the chamber filter plate frame. This allows it to stably withstand the extremely strong compressive force generated during the operation of an ultra-high pressure filter press, making it more suitable for the working environment of ultra-high pressure filter presses.

[0016] Meanwhile, the first frame of this utility model covers the second frame, and the second frame is embedded in the plate, forming a three-layer structure of plate, second frame and first frame. This structure builds a gradient load-bearing system from the inside to the outside, providing basic reinforcement support for the frame. The outer first frame further covers and strengthens, greatly improving the overall impact and tensile strength of the frame. At the same time, the three-layer structure can also evenly distribute the fastening stress generated by the first locking part and the second locking part to the entire frame, avoiding cracking and damage caused by stress concentration in local areas, effectively extending the service life of the filter plate and ensuring long-term stable operation of the filter plate.

[0017] Furthermore, this utility model provides a first groove and a second groove on the first frame, with the first locking part and the second locking part respectively positioned within the first groove and the second groove. The array-like layout of the grooves not only enables precise positioning of the locking part but also ensures that the locking part is fully embedded within the frame structure, without protruding from the outer surface of the filter plate frame, thus ensuring the overall frame of the chamber filter plate remains flat. This design, when assembling filter plates to form a sealed filter chamber, avoids problems such as the adjacent filter plate frames not fitting tightly due to protruding locking parts, or localized wear and deformation of the frames during the compression and stacking process. This not only ensures the sealing of the filter chamber but also reduces damage to the frames during assembly, further improving the overall structural integrity and performance of the frame.

[0018] Furthermore, a first gap is reserved between the end faces of the first frame and the plate in this utility model. The size of this gap is designed to fully adapt to the normal compression deformation range of the plate (such as a traditional polypropylene plate) under ultra-high pressure conditions. This provides sufficient deformation buffer space for the plate, preventing rigid collisions between the plate and the first frame when the plate is compressed and deformed, thus avoiding damage. When the plate is compressed and deformed to a certain extent due to ultra-high pressure, the first frame and the second frame can take over the pressure-bearing task of the entire plate in a timely manner, forming a progressive protection mechanism for deformation buffering and subsequent load bearing. This effectively prevents the plate from failing due to excessive deformation and also prevents the frame from being damaged due to excessive impact force, thereby better protecting the overall structure of the frame and ensuring the continuous and stable operation of the filter plate under ultra-high pressure conditions.

[0019] In summary, the ultra-high pressure chamber filter plate with metal reinforcing frame involved in this utility model, by setting a first frame and a second frame made of metal around the plate body, combined with multi-layer structure collaboration, embedded installation of locking parts and gap buffer design, optimizes the filter plate frame in all aspects from multiple dimensions such as strength improvement, stress dispersion, assembly protection and deformation adaptation. It effectively solves the defects of insufficient strength and easy breakage of traditional filter plates under ultra-high pressure environment, significantly improves the performance and reliability of its frame under ultra-high pressure environment, and thus better adapts to the production process of ultra-high pressure filter press, ensuring the continuity and stability of the production process.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] As mentioned earlier, current traditional chamber filter plates are mostly made of polypropylene blends, manufactured through extrusion and compression molding, or directly using injection molding. When used in conjunction with ultra-high pressure filter presses, the extremely strong compressive force generated during operation can cause significant thinning and misalignment of the polypropylene filter plates under continuous stress, leading to filter plate malfunction and inability to function properly. Furthermore, the immense pressure within the filter chamber caused by ultra-high pressure conditions can easily cause the filter plates to burst, damaging the plates themselves, disrupting normal production, and posing safety hazards and threats to the safety of the working environment.

[0032] To address this issue, this utility model provides a chamber-type filter plate for use in ultra-high pressure filtration environments. By attaching a metal reinforcing frame around its perimeter, the performance of the chamber-type filter plate is improved, thereby solving the aforementioned problems. This utility model achieves its solution in the following way.

[0033] Example 1: Please refer to the instruction manual appendix. Figures 1 to 8 As shown in the figure, this embodiment provides an ultra-high pressure chamber filter plate with a metal reinforcing frame, which includes at least a plate body 1. The plate body 1 has fixing clips at its four corners, and reinforcing spaces are formed on its four sides. These reinforcing spaces include a first notch 11, a second notch 12, and a third notch 13. The plate body 1 is formed by molding or injection molding, and the first notch 11, the second notch 12, and the third notch 13 are all formed by cutting and grinding.

[0034] like Figure 6 As shown, in this embodiment, the first notch 11 is formed on the upper and lower surfaces of the plate 1 (for ease of description, the two surfaces with the largest area of ​​the chamber filter plate are defined as the upper surface and the lower surface, then correspondingly, in Figure 6 In this chamber-type filter plate, there are eight first notches 11 on the front, back, left, and right sides, and on the top and bottom four sides. Figure 5 As shown, the definition Figure 5 The direction of the middle arrow Y is the first direction, so the arrow Y and the opposite direction of its location are both on the first direction line, and the first notch 11 is opened towards the first direction line.

[0035] Correspondingly, the directions away from the four sides of plate 1 are the second directions, such as... Figure 5 As indicated by the middle arrow X (it should be noted that...) Figure 5 The arrows in the diagram only refer to the opening of the second notch 12 on the left side of plate 1. The second notches 12 in the other three directions are all in different second directions. To be precise, the four arrows X on the four sides are perpendicular to each other. (The same applies to the Z arrow below, which will not be elaborated further). The arrow X and its opposite direction form the second direction line, and the second notch 12 is opened towards this second direction line. Similarly, the line connecting the two fixing heads of plate 1 is the third direction line, and the third notch 13 is opened along this third direction line. Figure 5 The Z-arrow and its opposite direction are shown on the line.

[0036] In this first embodiment, as Figures 1 to 6 As shown, this utility model also includes four first frame bodies 2 and second frame bodies 3 made of metal materials. Both the first frame bodies 2 and second frame bodies 3 are manufactured using a one-piece molding process. The second frame body 3 has a second frame plate and second frame pieces fixed to the second frame plate. The second frame plate (the largest surface area, hereinafter the same) is perpendicular to the second direction line, and its longest and shortest sides are respectively along the third direction line and the first direction line. The second frame pieces are perpendicular to the second frame plate, thus forming a tilted, mountain-shaped second frame body 3. Figure 4 , Figure 7 As shown, the second frame piece is inserted into the second notch 12, and the second frame 3 is located in the third notch 13. This clamps the side of the plate 1.

[0037] In this first embodiment, as Figures 1 to 6 As shown, the first frame 2 has a first frame plate and a first frame piece fixed to the first frame plate. The first frame plate is arranged parallel to the second frame plate, and the first frame piece is arranged parallel to the second frame piece. The first frame piece and the first frame plate together form a convex-shaped covering notch, which includes a first notch 23 and a second notch 24. Figure 4 , Figure 7 As shown, by covering the notch, the first frame 2 covers the second frame 3 between the plate 1 and itself, the second frame piece is disposed in the first notch 23, and the second frame plate is disposed in the second notch 24.

[0038] The first frame piece is located within the first notch 11, and the first frame plate is located within the third notch 13. After covering the second frame plate, the first frame plate forms a thickness γ, which is less than or equal to the opening depth (or thickness) of the third notch 13.

[0039] like Figures 4 to 7As shown, after assembly, several evenly distributed, through-hole first fixing holes need to be made. These first fixing holes pass through the first frame 2, plate 1, second frame 3, plate 1, second frame 3, plate 1, second frame 3, plate 1, and first frame 2 sequentially from top to bottom. A first locking part 4 (e.g., a screw or nut, the same below) is provided in the first fixing hole to lock the plate 1, first frame 2, and second frame 3.

[0040] On its side, several evenly distributed second fixing holes are also required. These second fixing holes pass through the first frame 2, the second frame 3, and the plate 1 in sequence, from the outer edge of the plate 1 to the inside of the plate 1. A second locking part 5 is provided inside each hole for locking. In conjunction with the first locking part 4, the plate 1, the first frame 2, and the second frame 3 are locked in multiple dimensions, making the assembly more tight.

[0041] Example 2: Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment two. For example... Figures 3 to 6 As shown, in this second embodiment, the first frame plate has several arrayed first grooves 21, which are located around the first fixing hole and are used to receive the locking head of the first locking part 4. Similarly, the first frame plate has several arrayed second grooves 22, which are located around the second fixing hole and are used to receive the locking head of the second locking part 5. This ensures that neither the first locking part 4 nor the second locking part 5 protrudes from the edge of the first frame 2, thus making the frame more flat overall.

[0042] Example 3: Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment three. For example... Figure 8 As shown, in this third embodiment, the first frame plate of the first frame 2 is disposed within the first notch 11, and the depth of the first notch 11 is... Figure 8 In the diagram, β represents the thickness of the first frame plate, which is less than β. The difference in thickness is the first gap. Figure 8 As shown in the diagram, α. When plate 1 is compressed, plate 1 itself bears the pressure first until it deforms. When the deformation distance is greater than α, it comes into contact with the first frame plate. At this time, the first frame 2 acts as the pressure-bearing component and continues to bear the pressure.

[0043] Therefore, in summary, compared with the prior art, this utility model and its embodiments have the following advantages, including but not limited to: This utility model features a reinforcing space around the plate 1. The structural design of this reinforcing space precisely adapts to the installation requirements of the first frame 2 and the second frame 3, providing a stable foundation for the frames to be accommodated and positioned. Simultaneously, the first frame 2 and the second frame 3, made of metal, are installed within the reinforcing space. The two frames are then securely locked within the reinforcing space by the first locking part 4 and the second locking part 5. This effectively compensates for the insufficient strength of traditional polypropylene filter plate frames, significantly improving the overall rigidity and pressure-bearing capacity of the chamber filter plate frame. This allows it to stably withstand the extremely strong pressing force generated during the operation of the ultra-high pressure filter press, making it more suitable for the use requirements of the ultra-high pressure filter press working environment.

[0044] Meanwhile, the first frame 2 of this utility model covers the second frame 3, and the second frame 3 is embedded in the plate 1, forming a three-layer structure of plate 1, second frame 3, and first frame 2. This structure builds a gradient load-bearing system from the inside out, providing basic reinforcement support for the frame. The outer first frame 2 further covers and strengthens the frame, greatly improving the overall impact and tensile strength of the frame. At the same time, the three-layer structure can also evenly distribute the fastening stress generated by the first locking part 4 and the second locking part 5 to the entire frame, avoiding cracking and damage caused by stress concentration in local areas, effectively extending the service life of the filter plate and ensuring long-term stable operation of the filter plate.

[0045] Furthermore, this utility model provides a first groove 21 and a second groove 22 on the first frame 2, and the first locking part 4 and the second locking part 5 are respectively disposed in the first groove 21 and the second groove 22. The array layout of the grooves not only enables precise positioning of the locking parts, but also ensures that the locking parts are fully embedded inside the frame structure and do not protrude from the outer surface of the filter plate frame, thereby ensuring that the overall frame of the chamber filter plate remains flat. When the filter plates are assembled to form a sealed filter chamber, this design avoids problems such as the adjacent filter plate frames not being able to fit tightly due to the protrusion of the locking parts, or the local wear and deformation of the frames during the compression and stacking process. This not only ensures the sealing of the filter chamber, but also reduces damage to the frames during the assembly process, further improving the overall structural integrity and performance of the frames.

[0046] Furthermore, a first gap is reserved between the end faces of the first frame 2 and the plate 1 of this utility model. The size of this gap is designed to fully adapt to the normal compression deformation range of the plate 1 (such as the traditional polypropylene plate 1) under ultra-high pressure conditions. It can provide sufficient deformation buffer space for the plate 1 and avoid rigid collision with the first frame 2 when the plate 1 is compressed and deformed, thus preventing damage. When the plate 1 is compressed and deformed to a certain extent due to ultra-high pressure, the first frame 2 and the second frame 3 can take over the pressure bearing task of the entire plate 1 in time, forming a progressive protection mechanism for deformation buffer and subsequent load bearing. This can effectively prevent the plate 1 from failing due to excessive deformation and avoid the frame from being damaged due to excessive impact force in an instant, thereby better protecting the overall structure of the frame and ensuring the continuous and stable operation of the filter plate under ultra-high pressure environment.

[0047] In summary, the ultra-high pressure chamber filter plate with metal reinforcing frame involved in this utility model, by setting a first frame 2 and a second frame 3 made of metal material around the plate body 1, combined with multi-layer structure collaboration, embedded installation of locking parts and gap buffer design, optimizes the filter plate frame in all aspects from multiple dimensions such as strength improvement, stress dispersion, assembly protection and deformation adaptation. It effectively solves the defects of insufficient strength and easy breakage of traditional filter plates under ultra-high pressure environment, significantly improves the performance and reliability of its frame under ultra-high pressure environment, and thus better adapts to the production process of ultra-high pressure filter press, ensuring the continuity and stability of the production process.

[0048] 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 this utility model and its equivalents, this utility model also intends to include these modifications and variations.
