Abstract
Description
Technical Field
[0001] This utility model belongs to the field of filtration equipment technology, and in particular relates to a high-precision stainless steel sintered filter element. Background Technology
[0002] Stainless steel sintered filter elements are filter elements made of stainless steel, possessing excellent filtration and mechanical properties. They are widely used in industries such as chemical, petroleum, pharmaceutical, and food processing. Stainless steel sintered filter elements are typically made by sintering stainless steel powder or wire mesh at high temperatures, forming a porous structure. Their structure can take various forms, including tubular, plate, disc, and other shapes, to meet different filtration needs. Based on the principles of surface and depth filtration, when fluid passes through the sintered filter element, particulate matter is trapped on the surface or inside the filter element, thus achieving the purpose of filtration. However, it still has the following drawbacks in practical use:
[0003] In the operation of stainless steel sintered filter elements, a sudden increase in the pressure of the filtered fluid can easily cause an impact on the filter element. When the filter element is subjected to an impact, the filter structure is prone to deformation, affecting subsequent filtration operations.
[0004] Secondly, during the filtration process, the stainless steel filter element is directly supported in the filtration equipment. As the filtration work progresses, the pressure of the fluid can easily cause the filter element to deform, and the filter element itself does not have good resistance to deformation. Utility Model Content
[0005] The purpose of this utility model is to provide a high-precision stainless steel sintered filter element. By setting up a support mesh, a skeleton assembly, an elastic assembly, a sieve plate, and an outer fixing plate, it solves the problem that the stainless steel sintered filter element itself has insufficient resistance to deformation, and that the filter structure is prone to deformation when the filter element is subjected to impact.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a high-precision stainless steel sintered filter element, comprising a support mesh, a skeleton assembly, an elastic assembly, a sieve plate, and an outer fixing plate. A sieve plate is fixed to the upper part of the two outer fixing plates, and an elastic assembly is fixed to the bottom of the sieve plate. A support mesh is disposed between the two outer fixing plates below the elastic assembly. Skeleton assemblies are fixed to the top and bottom of the support mesh. The two skeleton assemblies are symmetrically arranged, with one skeleton assembly positioned between the support mesh and the elastic assembly. During operation, the support mesh supports the two skeleton assemblies, ensuring sufficient support for the elastic assembly. The elastic assembly absorbs the impact on the sieve plate during filtration. Filter sheet one and filter sheet two are fixed to the sieve plate.
[0008] Furthermore, the skeleton assembly includes support bars and elastic columns, with elastic columns disposed between adjacent support bars. The skeleton assists in supporting the fixing plate through the cooperation of the support bars and elastic columns.
[0009] Furthermore, the skeleton assembly also includes a fixing plate and openings. The fixing plate has openings that are uniformly and vertically through it. When the skeleton assembly is in operation, the openings on the fixing plate transport the fluid.
[0010] Furthermore, both sides of the support net are fixed with sealing plates, and the two sealing plates are respectively fixed to the two outer fixing plates. Both ends of the elastic column are fixed to the outer fixing plates, and both ends of the support strip are respectively fixed to the two outer fixing plates at their respective close ends. Both sides of the fixing plate are fixed to the two outer fixing plates at their respective close ends. Moreover, the support strip and elastic column of the same frame assembly are all arranged between the fixing plate and the support net. The sealing plates on both sides of the support net increase the connection strength between the support net and the outer fixing plates.
[0011] Furthermore, the elastic component includes elastic strip one and elastic strip two, both of which are curved and are woven together in a crisscross pattern to effectively reduce the impact on the screen plate during operation.
[0012] Furthermore, the two ends of the elastic strip one are respectively fixed to the side of the two outer fixing plates that are close to each other. The top of the screen plate is fixed with filter sheet one, and the top of filter sheet one is fixed with filter sheet two. The two sides of filter sheet one are respectively fixed to the upper part between the two outer fixing plates, so that during operation, after the fluid is initially filtered by filter sheet two, it is transported to filter sheet one for further filtration, and then transported to the screen plate and passes through the elastic component.
[0013] This utility model has the following beneficial effects:
[0014] This invention solves the problem of insufficient deformation resistance of stainless steel sintered filter elements by setting up a support net, a skeleton assembly, and an outer fixing plate. After filtration, the fluid passes through the elastic assembly and is transported to the upper skeleton, then to the support net, and finally to the lower skeleton assembly and output. During operation, the fixing plate evenly distributes the force on the support bar and the elastic column. With the sealing plate connected on the support net, the two outer fixing plates are stably installed and fixed between the two outer fixing plates, ensuring stable support for filter element one and filter element two during operation, thus improving the deformation resistance of the stainless steel sintered filter element itself.
[0015] This invention solves the problem of filter structure deformation when the filter element is impacted by setting up a support net, a skeleton assembly, an elastic assembly, a sieve plate, and an outer fixing plate. When the sieve plate and the filter sheets 1 and 2 above it are working, the fluid first flows through the filter sheet 2, then through the filter sheet 1, and is filtered by the filter sheets 1 and 2. After filtration, the fluid is transported to the elastic assembly through the sieve plate. When the pressure of the filtered fluid suddenly increases and impacts the filter sheets 1 and 2 and the sieve, the impact is transmitted to the elastic strips 1 and 2 of the elastic assembly, relieving the impact and reducing the impact of liquid pressure on the filtration of the filter sheets 1 and 2, thus reducing the deformation of the filter structure after the filter element is impacted.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1
[0025] Please see Figure 1-3 This utility model is a high-precision stainless steel sintered filter element, including a support mesh 1, a skeleton assembly 2, an elastic assembly 3, a sieve plate 4, and an outer fixing plate 5. The upper part of the two outer fixing plates 5 is fixed together with the sieve plate 4. The outer fixing plates 5 connect the support mesh 1, skeleton assembly 2, elastic assembly 3, and sieve plate 4 together to form a complete filter structure. The bottom of the sieve plate 4 is fixed with the elastic assembly 3, which provides elastic support for the sieve plate 4 during filtration. The support mesh 1 is arranged between the two outer fixing plates 5 below the elastic assembly 3, and the support mesh 1 provides support between the two skeleton assemblies 2. The top and bottom of the support mesh 1 are both fixed with skeleton assemblies 2. The two skeleton assemblies 2 are arranged symmetrically. One skeleton assembly 2 is arranged between the support mesh 1 and the elastic assembly 3, and the skeleton assembly 2 provides support for the support mesh 1 and the sieve plate 4.
[0026] Specifically, the skeleton assembly 2 includes support bars 201 and elastic columns 202. Elastic columns 202 are provided between adjacent support bars 201. The support bars 201 provide support for the fixing plate 203 on the support net 1, and the gap between adjacent support bars 201 is supported by the elastic columns 202. During filtration, fluid passing through the openings 204 on the fixing plate 203 is transported between adjacent support bars 201, and then transported between the support bars 201 into the support net 1, and finally passes through the skeleton assembly 2 below and then exits.
[0027] Furthermore, the skeleton assembly 2 also includes a fixing plate 203 and an opening 204. The fixing plate 203 has a uniformly vertically through-hole 204. When the skeleton assembly 2 is in operation, the opening 204 on the fixing plate 203 is used to allow filtered fluid to pass through.
[0028] Furthermore, both sides of the support net 1 are fixed with sealing plates 101, and the two sealing plates 101 are respectively fixed to the two outer fixing plates 5. Both ends of the elastic column 202 are fixed to the outer fixing plates 5. Both ends of the support strip 201 are respectively fixed to the two outer fixing plates 5 at their respective close ends. Both sides of the fixing plate 203 are fixed to the two outer fixing plates 5 at their respective close ends. Moreover, the support strip 201 and elastic column 202 of the same frame assembly 2 are both set between the fixing plate 203 and the support net 1. The frame assembly 2 is stably fixed between the two outer fixing plates 5. The sealing plates 101 on both sides of the support net 1 are fixed to the outer fixing plates 5, so that the support net 1 and the outer fixing plates 5 are stably connected during operation.
[0029] The operation process of this embodiment is as follows: During operation, the filtered fluid passes through the elastic component 3 and is then transported to the upper frame, then to the support net 1, and after passing through the support net 1, it is transported to the lower frame component 2 and output. During operation, the fixing plate 203 evenly distributes the force on the support bar 201 and the elastic column 202. It is fixed to the outer fixing plate 5 by the sealing plates 101 on both sides of the support net 1 to ensure the overall structural stability and ensure that the filter sheet 401 and filter sheet 402 are provided with stable support during operation. Specific Implementation Example 2
[0030] Please see Figure 1-5 Based on the first specific embodiment, the elastic component 3 includes an elastic strip 301 and an elastic strip 302. All elastic strips 301 and 302 are curved and are woven together in a crisscross pattern. The elastic component 3 provides elastic support to the sieve plate 4 through the elastic strips 301 and 302 and transmits pressure to the skeleton component 2.
[0031] Specifically, the two ends of the elastic strip 301 are fixed to the sides of the two outer fixing plates 5 that are close to each other. The top of the sieve plate 4 is fixed with filter sheet 401, and the top of filter sheet 401 is fixed with filter sheet 402. The two sides of filter sheet 401 are fixed to the upper part between the two outer fixing plates 5. Filter sheet 402 performs coarse filtration, and filter sheet 401 performs fine filtration. The fluid to be filtered is initially filtered by filter sheet 401 and further filtered by filter sheet 402. Filter sheet 401 and filter sheet 402 are supported on the elastic component 3 by the sieve plate 4.
[0032] The operation process of this embodiment is as follows: When the sieve plate 4 and the filter sheet 401 and filter sheet 402 above it are working, the fluid first flows through the filter sheet 402, and then is conveyed through the filter sheet 401. It is filtered by the filter sheet 401 and filter sheet 402. After filtration, the fluid is conveyed to the elastic component 3 through the sieve plate 4. When the pressure of the filtered fluid suddenly increases, it impacts the filter sheet 401, filter sheet 402 and the sieve. The impact is then transmitted to the elastic strip 301 and elastic strip 302 included in the elastic component 3, which relieves the impact and reduces the impact of the liquid pressure on the filtration of the filter sheet 401 and filter sheet 402.
