Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a filter plate hanger and a filter press. Background Technology

[0002] Filter presses are solid-liquid separation devices commonly used in industries such as chemical, pharmaceutical, and food processing. In the chemical industry, filter presses are frequently used in solid-liquid separation processes during the production of petrochemicals, fertilizers, and dyes, effectively improving production efficiency, reducing waste disposal costs, and ensuring product quality. In the pharmaceutical industry, filter presses are widely used in solid-liquid separation processes during drug production. Their high-efficiency filtration performance and reliable control system ensure the purity and quality of drugs, meeting the stringent requirements of pharmaceutical production. In the food industry, filter presses are commonly used in solid-liquid separation processes during the production of fruit juices, wines, and edible oils, enabling rapid filtration and separation of food raw materials, improving production efficiency, and ensuring food hygiene and safety. In summary, filter presses have a wide range of applications in the chemical, pharmaceutical, and food industries, providing reliable technical support for solid-liquid separation in production processes and promoting the development and progress of these industries.

[0003] Based on their machine type, filter presses are mainly divided into three types: vertical, side-beam, and high-beam. In a high-beam filter press, the filter plates are suspended on beams of the frame, not in contact with the filtered or dewatered product or sludge. This type is suitable for clean environments, has a particularly stable structure, and a high degree of automation. Compared to other filtration equipment, the high-beam filter press can maximize the dryness of the filter cake or product, while having lower power consumption and lower maintenance costs.

[0004] In existing high-beam filter presses, filter plates are hoisted using welded filter plate hangers. However, in this method, when there is a large amount of filter residue between the filter plates, the filter plates may tilt, causing the top rollers of the filter plates to lift off the track. This results in problems such as premature disengagement and hook jumping during filter plate unloading. This is because the filter plate hangers are formed by welding multiple components, and the welding dimensions require high precision. Due to welding deformation and processing precision, the dimensions of each filter plate hanger cannot be completely consistent. This causes displacement of the dimensions of the filter plate hanger and its matching hook after installation, preventing normal plate unloading. Utility Model Content

[0005] The purpose of this invention is to solve the problems of existing high-beam filter presses using welded filter plate hangers, where welding deformation leads to inconsistent dimensions among the hangers, causing the filter plates to tilt under filter cake load, rollers to derail, and resulting in hook detachment and jumping during cake unloading. This invention provides a filter plate hanger and filter press that eliminates the uncontrollable deformation caused by welding, ensures overall dimensional consistency, and significantly improves the operational stability of the filter plates under full-load filter cake conditions.

[0006] To solve the above-mentioned technical problems, this utility model discloses a filter plate hanger for connecting filter plates to a frame, wherein the frame is provided with a slide rail; the filter plate hanger includes: a base plate extending along a first direction, the base plate being fixedly connected to the filter plate; a wing plate extending along a second direction, the wing plate being disposed above the base plate and fixedly connected to the base plate; the second direction intersects with the first direction; two roller shafts, respectively disposed at both ends of the wing plate in the second direction and on both sides of the wing plate in the thickness direction; the two roller shafts extending along the first direction and in opposite directions; the two roller shafts being used to mount rollers, the rollers being slidably connected to the slide rail on the frame; the filter plate hanger is integrally formed.

[0007] Using the above technical solution, the filter plate hanger is integrally molded, integrating the base plate, wing plates, and roller shafts into a single structure. The base plate extends along a first direction to fix the filter plate, while the wing plates extend along a second direction to form a supporting frame. Two roller shafts extending in opposite directions are located at both ends of the wing plates and are used for sliding engagement with the frame slide rails. This integrated design eliminates the risk of welding deformation, ensures overall dimensional consistency, and significantly improves the operational stability of the filter plate under full-load filter cake conditions.

[0008] According to another specific embodiment of the present invention, the two roller shafts include a first roller shaft and a second roller shaft; the wing plate is triangular in shape, and the wing plate includes:

[0012] According to another specific embodiment of the present invention, the wing plate is provided with a through hole.

[0013] The above technical solution includes through holes on the wing plate, which facilitates demolding during casting and reduces weight, making it easier to install and replace the filter plate bracket.

[0014] According to another specific embodiment of the present invention, a first side is defined between the first end and the third end, and a second side is defined between the second end and the third end; the filter plate hanger further includes:

[0015] A first stiffener is provided on the side of the wing plate where the first roller shaft is located; the first stiffener includes a first connecting edge and a second connecting edge connected to each other, the first connecting edge being connected to the first edge of the wing plate, and the second connecting edge being connected to the bottom plate;

[0017] By adopting the above technical solution, the setting of the first and second stiffeners significantly enhances the overall rigidity and torsional resistance of the filter plate hanger, effectively disperses the load stress transmitted by the roller shaft, and prevents the deformation of the wing plate or cracking of the connection part under high pressure filtration conditions.

[0018] According to another specific embodiment of the present invention, the two roller shafts are at the same height.

[0019] By adopting the above technical solution, the two roller shafts are at the same height, ensuring the stable movement of the filter plate, avoiding unilateral wear caused by the height difference between the two roller shafts, and ensuring the stable operation of the filter press.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0039] refer to Figure 1 This application provides a filter press, including a frame (not shown in the figure), filter plates 100, and filter plate hangers 200. The filter plate hangers 200 connect the filter plates 100 to the frame.

[0040] Specifically, the frame is equipped with a slide rail, and the filter plate hanger 200 is connected to a roller 300. The roller 300 is slidably connected to the slide rail, thereby enabling the filter plate hanger 200 to connect the filter plate 100 to the frame.

[0041] like Figure 1 and Figure 2 As shown, the filter plate bracket 200 includes a base plate 210, a wing plate 220, and two roller shafts 230. The base plate 210 extends along the first direction X and is fixedly connected to the filter plate 100.

[0042] Specifically, such as Figure 1 and Figure 2As shown, the filter plate 100 and the base plate 210 are fixedly connected by a filter plate hanger 400. The filter plate 100 is rectangular, and the filter plate hanger 400 is an open rectangular shape. The filter plate hanger 400 includes a horizontal plate 410 and two side plates 420 fixedly connected to both sides of the horizontal plate 410. The horizontal plate 410 is spaced apart from the top wall of the filter plate 100, and the two side plates 420 correspond one-to-one with the two side walls of the filter plate 100 in the width direction X and are fixedly connected by screws. The first direction X of the base plate 210 of the filter plate hanger 200 is also the width direction of the filter plate 100, and it is connected to the horizontal plate 410 of the filter plate hanger 400 by screws, thereby realizing the fixed connection between the base plate 210 and the filter plate 100.

[0043] like Figure 2 As shown, the wing plate 220 extends along the second direction Y, is disposed above the base plate 210, and is fixedly connected to the base plate 210; the second direction Y intersects with the first direction X. For example, the angle between the second direction Y and the first direction X is 60°. However, this application does not limit this, for example, the angle between the second direction Y and the first direction X can be 45°, 50°, etc.

[0044] refer to Figure 2 and Figure 3 ,in, Figure 3 yes Figure 2 The view after rotating 180°. In this embodiment, the wing plate 220 is approximately in the shape of an isosceles triangle, and the second direction Y is the direction in which the base of the isosceles triangle extends. The wing plate 220 includes a first end 221, a second end 222, and a third end 223, wherein the first end 221 and the second end 222 correspond to the positions of the two base angles of the isosceles triangle wing plate 220, the first end 221 and the third end 223 define a first side 224, and the second end 222 and the third end 223 define a second side 225. The third end 223 corresponds to the position of the apex angle of the isosceles triangle wing plate 220, and the third end 223 is fixedly connected to the midpoint of the base plate 210 in the first direction X.

[0045] In other words, the wing plate 220 includes a first plate portion 220a, a second plate portion 220b, and a central shaft portion 220c located between the first plate portion 220a and the second plate portion 220b. The first plate portion 220a includes the aforementioned first end portion 221 and first side 224, and the second plate portion 220b includes the aforementioned second end portion 222 and second side 225. The central shaft portion 220c connects to the midpoint of the base plate 210 in the first direction X. The first plate portion 220a and the second plate portion 220b are arranged approximately symmetrically about the central shaft portion 220c. The first plate portion 220a and the second plate portion 220b are symmetrically provided with through holes 226, which facilitate demolding during casting and also reduce weight, making installation and replacement easier.

[0046] like Figure 1 and Figure 2 As shown, two roller shafts 230 are respectively located at both ends of the second direction Y of the wing plate 220, and on both sides of the thickness direction of the wing plate 220; the two roller shafts 230 extend along the first direction X and in opposite directions.

[0047] In this embodiment, the two roller shafts 230 include a first roller shaft 231 and a second roller shaft 232. The first roller shaft 231 is located at a first end 221, and the second roller shaft 232 is located at a second end 222. The first roller shaft 231 and the second roller shaft 232 are respectively located on both sides of the wing plate 220 in the thickness direction, and both extend towards the first direction X and away from the wing plate 220; that is, the first roller shaft 231 and the second roller shaft 232 extend in opposite directions.

[0048] For example, the first roller shaft 231 and the second roller shaft 232 are symmetrically arranged at both ends of the wing plate 220 in the second direction Y.

[0049] Rollers 300 are installed on both roller shafts 230. The rollers 300 are slidably connected to the slide rails on the frame, which enables the filter plate 100 to move on the slide rails.

[0050] In this embodiment, the filter plate holder 200 is integrally formed. Specifically, the filter plate holder 200 is formed in one piece by mold casting.

[0051] Using the above technical solution, the filter plate hanger 200 is integrally formed, integrating the base plate 210, wing plate 220, and roller shaft 230 into a single structure. The base plate 210 extends along the first direction X to fix the filter plate 100, the wing plate 220 extends along the second direction Y to form a supporting frame, and two back-extending roller shafts 230 are located at both ends of the wing plate 220 and slide in cooperation with the frame slide rail. This integrated design eliminates the risk of welding deformation, ensures overall dimensional consistency, and significantly improves the operational stability of the filter plate 100 under full-load filter cake conditions, thereby enhancing the stability and service life of the filter press.

[0052] Optionally, the filter plate hanger 200 is precision machined in a CNC machining center for key dimensions, and then clamped in a uniform tooling fixture to further ensure dimensional consistency.

[0053] Furthermore, such as Figures 2 to 4 As shown, the filter plate hanger 200 also includes a first stiffener 241 and a second stiffener 242. Wherein, as... Figure 2 and Figure 3As shown, a first stiffener 241 is disposed on the side of the wing plate 220 where the first roller shaft 231 is located; the first stiffener 241 includes a first connecting edge 241a and a second connecting edge 241b connected together, the first connecting edge 241a connecting to the first edge 224 of the wing plate 220, and the second connecting edge 241b connecting to the base plate 210. Exemplarily, the first stiffener 241 is triangular in shape, connecting the first plate portion 220a of the wing plate 220 and the base plate 210.

[0054] like Figure 3 and Figure 4 As shown, the second stiffener 242 is disposed on the side of the wing plate 220 where the second roller shaft 230 is located; the second stiffener 242 includes a third connecting edge 242a and a fourth connecting edge 242b connected to each other, the third connecting edge 242a connecting to the second edge 225 of the wing plate 220, and the fourth connecting edge 242b connecting to the base plate 210. Exemplarily, the second stiffener 242 is triangular in shape, connecting the second plate portion 220b of the wing plate 220 and the base plate 210.

[0055] The arrangement of the first stiffener 241 and the second stiffener 242 significantly enhances the overall rigidity and torsional resistance of the filter plate hanger 200, effectively disperses the load stress transmitted by the roller shaft 230, prevents deformation of the wing plate 220 or cracking of the connection part under high pressure filtration conditions, and ensures the long-term stable operation of the filter plate 100 on the slide rail.

[0056] It is understood that the filter press includes multiple filter plates 100 and multiple filter plate brackets 200 corresponding to each of them. Each filter plate bracket 200 is connected to the slide rail on the frame via rollers 300.

[0057] refer to Figure 2 and Figure 3 The aforementioned filter plate hanger 200 also includes a hinge seat 250, which is located on the top of the wing plate 220 and is directly opposite the midpoint of the first direction X of the bottom plate 210 along the height direction Z. That is, the hinge seat 250 is located on the top of the central shaft portion 220c. The two hinge seats 250 of two adjacent filter plate hangers 200 are connected by filter plate hooks 500.

[0058] Specifically, the hinge seat 250 includes a slot 251 and a hook surface 252. The hook surface 252 is located outside the slot 251, and the bottom wall of the slot 251 and the hook surface 252 are at a set angle, such as 80°, 85°, 90°, etc.

[0059] refer to Figure 5 The filter plate hook 500 includes hook heads 501 and grooves 502 located at both ends along its length. Exemplarily, the hook heads 501 are downwardly bent hooks. The grooves 502 are generally U-shaped.

[0060] refer to Figure 6 and Figure 7 The hinge seat 250 is located in the groove 502 and is connected by the pin 260; the hook head 501 extends into the slot 251 of the hinge seat 250 of the adjacent filter plate bracket 200 and hooks the hooking surface 252 of the hinge seat 250.

[0061] That is, one end of the filter plate hook 500 with a groove 502 is connected to the hinge seat 250 of a filter plate bracket 200, and the other end with a hook head 501 hooks the hooking surface 252 of the hinge seat 250 of another adjacent filter plate bracket 200, so that multiple filter plates 100 are connected through multiple filter plate hooks 500, thereby realizing synchronous motion control of multiple filter plates 100.
