Description

Technical Field

[0001] This utility model relates to the field of oil and gas filter element technology, and specifically to an oil and gas filter element suitable for high-pressure environments. Background Technology

[0002] Air filter elements are core filtration components in hydraulic, lubrication, and compressed air systems. Their technological development is closely related to modern industry's requirements for equipment reliability, efficiency, and lifespan.

[0003] A search revealed a utility model patent with publication number CN210331963U, which discloses a filter element for exhaust gas recovery, specifically relating to the field of filter element technology. The filter element includes a cylindrical filter structure with openings at opposite ends; a top cover and a base, respectively disposed at the openings of the cylindrical filter structure; and the top cover and the base are fixedly connected by a connecting rod that penetrates the cylindrical filter structure axially. This utility model provides a filter element for exhaust gas recovery that is easy to assemble and securely connected.

[0004] The aforementioned patent only uses a filter element consisting of upper and lower end caps and a filter cloth fixed between the end caps. Oil and gas enter the filter cloth through the air inlet on the end caps, then pass through the filter cloth and are discharged, thus completing the filtration of oil in the exhaust gas. However, it cannot fully filter oil containing multiple molecular structures, requiring the replacement of a filter structure with a lower precision to complete the oil filtration. The filtration process is cumbersome, and because the filter structure lacks the participation of high-strength materials for reinforcement, the filter structure is not suitable for use in high-pressure environments, reducing its practicality.

[0005] Therefore, it is necessary to invent an oil and gas filter element suitable for high-pressure environments to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an oil and gas filter element suitable for high-pressure environments. It employs a design combining vertical corrugated reinforcement material and a mesh structure, comprising corrugated filter media one, two, three, and four in a single integrated structure. This structure ensures both extremely high pressure resistance and sufficient flow area. Furthermore, by using adhesive-bonded reinforcing ribs one and two at the pleats and troughs of corrugated filter media one, two, three, and four, the filter elements are made more stable and durable. The filter media is integrated into a robust whole, greatly enhancing its pressure resistance and preventing deformation due to compression between pleats. Combined with the outer metal mesh, it effectively prevents the filter media from bulging or deforming under high pressure differentials, providing auxiliary protection. This addresses the problem that existing technologies cannot adequately filter oil contaminants containing multiple molecular structures, requiring the replacement of filters with less precise ones. This cumbersome filtration process, coupled with the lack of high-strength materials in the filter structure, makes it unsuitable for high-pressure environments, reducing its applicability.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an oil and gas filter element suitable for high-pressure environments, comprising a partition plate, wherein a through hole is provided inside the partition plate, a corrugated filter material one is fixedly disposed at the bottom of the partition plate, a corrugated filter material two is fixedly disposed at the bottom of the partition plate inside the corrugated filter material one, a corrugated filter material three is fixedly disposed at the top of the partition plate, a corrugated filter material four is fixedly disposed at the top of the partition plate inside the corrugated filter material three, and a metal outer mesh is fixed at the bottom and the bottom of the partition plate outside the corrugated filter material one and the corrugated filter material three.

[0008] Preferably, the outer surfaces of the corrugated filter material one and the corrugated filter material three are uniformly fitted with adhesive-cured ribs one, and the outer surfaces of the corrugated filter material two and the corrugated filter material four are uniformly fitted with adhesive-cured ribs two.

[0009] Preferably, a filter chamber is provided between the corrugated filter material one and the metal outer mesh, located below the middle partition, and a filter chamber is provided between the corrugated filter material one and the corrugated filter material two.

[0010] Preferably, a filter chamber three is provided between the corrugated filter material three and the metal outer mesh, located above the middle partition, and a filter chamber four is provided between the corrugated filter material three and the corrugated filter material four.

[0011] Preferably, the inner surfaces of corrugated filter material one and corrugated filter material three are fixedly connected with metal mesh one, and the inner surfaces of corrugated filter material two and corrugated filter material four are fixedly connected with metal mesh two.

[0012] Preferably, the outer ends of the corrugated filter media one, corrugated filter media two, corrugated filter media three, and corrugated filter media four are all fixedly connected with end caps.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. By adopting a design that combines vertical corrugated reinforcement material with mesh, the corrugated filter media I, II, III, and IV form an integral structure. This structure ensures both extremely high compressive strength and provides sufficient flow area. Furthermore, by using adhesive-bonded reinforcing ribs I and II at the pleats and troughs of the corrugated filter media I, II, III, and IV, they become a robust whole, greatly enhancing compressive strength and preventing deformation due to compression between pleats. Combined with the metal outer mesh, this effectively prevents the filter media from bulging or deforming under high pressure differential, providing auxiliary protection. 2. By using a partition to divide the corrugated filter media 1, 2, 3, and 4 into upper and lower filtration structures, the oil and gas to be filtered must pass through the through holes in the partition multiple times within the filter element body. Compared with existing oil and gas filter elements that only have a single-stage filtration structure, this method can achieve better filtration results. Furthermore, by increasing the filtration precision of the corrugated filter media 1, 2, 3, and 4 sequentially along the gas flow direction, multi-stage filtration of oil and gas can be achieved, thus improving the filtration effect.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-5 The oil and gas filter element shown is suitable for high-pressure environments, including a partition plate 1. The partition plate 1 has a through hole 2 inside, and the through hole 2 connects the inner cavities of filter chamber 1 7, filter chamber 2 8, filter chamber 3 9 and filter chamber 4 10 in the device. A corrugated filter media 3 is fixedly installed at the bottom of the partition 1. A corrugated filter media 4 located inside the corrugated filter media 3 is fixedly installed at the bottom of the partition 1. A corrugated filter media 5 is fixedly installed at the top of the partition 1. A corrugated filter media 6 located inside the corrugated filter media 5 is fixedly installed at the top of the partition 1. The vertical corrugated structure of the corrugated filter media 3, 4, 5, and 6 has extremely high compressive strength. In addition, the uniform arrangement of filter holes provides sufficient flow area. The filtration accuracy of the corrugated filter media 3, 4, 5, and 6 increases sequentially along the gas flow direction. Correspondingly, the filtration accuracy of the corrugated filter media 3 decreases, reducing its pressure. The filtration of oil and gas will be more uniform. At the same time, it can prevent oil from clogging the filter element body, thereby increasing the service life of the filter element body. The bottom of the partition plate 1 and the bottom of the partition plate 1 are both fixed with a metal outer mesh 13 located outside the corrugated filter media 1 3 and corrugated filter media 3 5. The metal outer mesh 13 is made of galvanized steel mesh and forms an outer cover structure to wrap the corrugated filter media 1 3, corrugated filter media 2 4, corrugated filter media 3 5 and corrugated filter media 4 6, which plays a good protective role and prevents the filter media from "bulging" or deforming under high pressure differential.

[0019] The outer surfaces of corrugated filter media 1 (3) and corrugated filter media 3 (5) are uniformly fitted with adhesive-cured ribs 1 (14), and the outer surfaces of corrugated filter media 2 (4) and corrugated filter media 4 (6) are uniformly fitted with adhesive-cured ribs 2 (15). The adhesive-cured ribs 1 (14) and 2 (15) improve the structural strength between the pleats of corrugated filter media 1 (3), corrugated filter media 2 (4), corrugated filter media 3 (5), and corrugated filter media 4 (6), greatly enhancing their compressive strength and preventing deformation due to compression between the pleats.

[0020] A filter chamber 7 located below the partition plate 1 is provided between the corrugated filter material 3 and the metal outer mesh 13, and a filter chamber 8 is provided between the corrugated filter material 3 and the corrugated filter material 4.

[0021] A filter chamber 39 is provided between the corrugated filter media 35 and the metal outer mesh 13, located above the middle partition 1, and a filter chamber 40 is provided between the corrugated filter media 35 and the corrugated filter media 46.

[0022] The inner surfaces of corrugated filter media 1 3 and corrugated filter media 3 5 are fixedly connected with metal mesh 1 11, and the inner surfaces of corrugated filter media 2 4 and corrugated filter media 4 6 are fixedly connected with metal mesh 2 12. The setting of metal mesh 1 11 and metal mesh 2 12 can enhance the internal support effect of corrugated filter media 1 3, corrugated filter media 2 4, corrugated filter media 3 5 and corrugated filter media 4 6.

[0023] The outer ends of corrugated filter media 1 (3), corrugated filter media 2 (4), corrugated filter media 3 (5), and corrugated filter media 4 (6) are all fixedly connected with end caps 16. The end caps 16 are metal end caps and are firmly connected to the filter media by welding or high-strength epoxy resin adhesive.

[0024] The working principle of this practical application is as follows: When preparing to filter oil and gas, the oil and gas entering the filter passes through the metal outer mesh 13 and through the corrugated filter material 3 in the first filter chamber 7, then through the corrugated filter material 4 in the second filter chamber 8, and enters the corrugated filter material 6 through the through hole 2 on the partition plate 1, and finally passes through the corrugated filter material 5 to complete the filtration of oil and gas in the exhaust gas. This allows for four-stage filtration of oil and gas, thereby improving the filtration efficiency of oil and gas.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
