Description

Technical Field

[0001] This utility model relates to the field of ultra-high pressure filter technology, and in particular to an ultra-high pressure filter that is easy to disassemble and clean. Background Technology

[0002] Ultra-high pressure filters are widely used in many industrial fields such as petrochemicals and hydraulic systems. Their main function is to filter out impurities and particles in fluids to ensure the normal operation of the system and the service life of the equipment.

[0003] However, after long-term use, the internal filter element of existing ultra-high pressure filters is easily clogged by impurities, requiring cleaning or replacement of the filter element.

[0004] However, traditional ultra-high pressure filters are often complex to disassemble and assemble, requiring specialized tools and taking a long time. This not only increases the time cost of equipment maintenance, but may also damage the filter due to improper disassembly and assembly, affecting its filtration performance and service life.

[0005] Therefore, this utility model proposes an ultra-high pressure filter that is easy to disassemble and clean. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies and propose an ultra-high pressure filter that is easy to disassemble and clean.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an ultra-high pressure filter that is easy to disassemble and clean, comprising:

[0008] Filter valves;

[0009] The filter cartridge assembly is located at the bottom of the filter valve. The filter cartridge assembly is interlocked with the bottom of the filter valve by a limiting seat. The bottom of the filter cartridge assembly is provided with a filter cartridge that penetrates the filter valve. The inner wall of the limiting seat is provided with a snap-fit ​​groove. A limiting sleeve is snap-fitted and fixed on the filter cartridge by the snap-fit ​​groove. A limiting plate is provided on the limiting seat above the limiting sleeve.

[0010] The filter element assembly is located inside the filter cartridge assembly. The filter element assembly includes two filter elements, and filter plates are provided between the upper and lower sides of the two filter elements. A spring is provided below the filter plate at the bottom of the filter elements.

[0011] In a preferred embodiment, the top opening of the filter valve is threaded with an upper cap, and the filter valve is provided with an installation plate.

[0012] The beneficial effects of adopting the above-mentioned further solution are as follows: Under the action of the upper cap, the filter valve, filter cartridge assembly and filter element assembly are detachable. In use, after removing the upper cap, the filter cartridge assembly is inserted into the filter valve through the top of the filter valve, and then the filter element assembly is placed into the filter cartridge assembly, so that the filter valve, filter cartridge assembly and filter element assembly are separated, so as to facilitate disassembly and maintenance in the future. The filter valve is then installed and fixed by the mounting plate.

[0013] In a preferred embodiment, the limiting sleeve is provided with a snap-fit ​​block, and the limiting sleeve is snapped into the snap-fit ​​groove by the snap-fit ​​block.

[0014] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the snap-fit ​​block, the limiting sleeve is snapped together with the snap-fit ​​groove through the snap-fit ​​block, thereby limiting the limiting sleeve. In actual use, after the limiting sleeve is inserted into the snap-fit ​​groove through the snap-fit ​​block, it is rotated to one side, so that the limiting sleeve and the limiting seat are snapped together and limited.

[0015] In a preferred embodiment, one side of the snap-fit ​​groove is rotatably connected to a limiting rotating seat.

[0016] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the limiting rotating seat, the limiting sleeve is limited. After the limiting sleeve is inside the limiting seat, the limiting rotating seat is rotated to be directly above the limiting sleeve to limit the limiting sleeve, thus preventing the limiting sleeve from being misaligned inside the limiting seat and separating from the limiting seat during use.

[0017] In a preferred embodiment, the bottom of the limiting plate is provided with a magnetic attraction point, and the limiting plate is magnetically attracted to the top of the limiting seat through the magnetic attraction point.

[0018] The beneficial effects of adopting the above-mentioned further solution are: since the limiting rotating seat is rotatably connected inside the limiting seat, the limiting rotating seat is limited by the limiting plate during use, so as to prevent the limiting rotating seat from flipping upward and releasing the limiting sleeve during use. Furthermore, under the action of the magnetic attraction point, the limiting plate and the limiting seat are magnetically attracted and fixed to each other.

[0019] In a preferred embodiment, the diameter of the filter plate is adapted to the inner wall of the filter cartridge, and the diameter of the filter cotton is smaller than the diameter of the filter plate.

[0020] The beneficial effects of adopting the above-mentioned further solution are: since the diameter of the filter element plate is adapted to the inner wall of the filter cartridge, there is a gap between the filter element plate and the filter cartridge during use, which improves the filtration effect and further filters the liquid in the filter cartridge under the action of the filter cotton.

[0021] In a preferred embodiment, a cross is embedded within the limiting sleeve.

[0022] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the cross, the top of the limiting seat is limited, preventing the limiting seat from being misaligned after passing through the limiting sleeve, which would reduce the filtration effect.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] 1. In this utility model, since the filter valve, filter cartridge assembly and filter element assembly are separate structures, the advantage of this structure is that, during cleaning or maintenance, the upper cap is first unscrewed from the top of the filter valve, and the filter cartridge assembly is taken out from the filter valve. Then, the limiting plate is removed to release the limiting sleeve. After the limiting sleeve is released, the limiting sleeve is rotated to one side, and under the action of the spring, the filter element plate pushes the filter cotton out of the filter cartridge. The advantage of the detachable structure is that it is more convenient for later cleaning and maintenance.

[0025] 2. In this utility model, since the filter valve, filter cartridge assembly, and filter element assembly are separate structures, the advantage of this structure is that, during cleaning or maintenance, the upper cap is first unscrewed from the top of the filter valve, and the filter cartridge assembly is taken out from the filter valve. Then, the limiting plate is removed to release the limiting sleeve. After the limiting sleeve is released, the limiting sleeve is rotated to one side, and under the action of the spring, the filter element plate pushes the filter cotton out of the filter cartridge. The advantage of the detachable structure is that it is more convenient for later cleaning and maintenance. Attached Figure Description

[0034] 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.

[0035] like Figure 1-4 As shown, this utility model provides a technical solution: an ultra-high pressure filter that is easy to disassemble and clean, comprising: a filter valve 1; a filter cartridge assembly 2, the filter cartridge assembly 2 being disposed at the bottom of the filter valve 1, the filter cartridge assembly 2 being interlocked with the bottom of the filter valve 1 by a limiting seat 22, and a filter cartridge 21 penetrating the filter valve 1 being disposed at the bottom of the filter cartridge assembly 2, the inner wall of the limiting seat 22 being provided with a snap-fit ​​groove 211, a limiting sleeve 24 being snap-fitted and fixed on the filter cartridge 21 by the snap-fit ​​groove 211, and a limiting plate 23 being disposed on the limiting seat 22 above the limiting sleeve 24; and a filter element assembly 3, the filter element assembly 3 being disposed inside the filter cartridge assembly 2, the filter element assembly 3 including two filter elements 32, and a filter element plate 31 being disposed between the upper and lower sides of the two filter elements 32, with the filter element plate 31 located at the bottom of the filter elements 32. A spring 33 is provided below the filter valve 1, and a snap-fit ​​block 242 is provided on the limiting sleeve 24. The limiting sleeve 24 is snapped into the snap-fit ​​groove 211 by the snap-fit ​​block 242. Since the filter valve 1, filter cartridge assembly 2 and filter element assembly 3 are separate structures, the advantage of this structure is that, when cleaning or maintaining, first unscrew the top cap 11 from the top of the filter valve 1 and take the filter cartridge assembly 2 out of the filter valve 1. Then, remove the limiting plate 23 to release the limiting state of the limiting sleeve 24. After the limiting state of the limiting sleeve 24 is released, rotate the limiting sleeve 24 to one side, and under the action of the spring 33, the filter element plate 31 pushes the filter element cotton 32 out of the filter cartridge 21. The advantage of the detachable structure is that it is more convenient to clean and maintain in the later stage, which solves the technical problem of inconvenient cleaning of the device.

[0036] Going a step further, such as Figure 2 - Figure 4As shown: A limiting rotating seat 212 is rotatably connected to one side of the snap-fit ​​groove 211. A magnetic attraction point 231 is provided at the bottom of the limiting disk 23. The limiting disk 23 magnetically attracts the top of the limiting seat 22 through the magnetic attraction point 231. Under the action of the limiting rotating seat 212, the limiting sleeve 24 is limited. After the limiting sleeve 24 is inside the limiting seat 22, the limiting rotating seat 212 is rotated to directly above the limiting sleeve 24 to limit the limiting sleeve 24, preventing the limiting sleeve 24 from being in contact with the limiting seat 22 during use. After the limiting seat 22 is misaligned, it separates from the limiting seat 22. Since the limiting rotating seat 212 is rotatably connected inside the limiting seat 22, it is necessary to limit the limiting rotating seat 212 through the limiting plate 23 during use to prevent the limiting rotating seat 212 from flipping upward and releasing the limiting sleeve 24 during use. Furthermore, under the action of the magnetic attraction point 231, the limiting plate 23 and the limiting seat 22 are magnetically attracted and fixed to each other, thus solving the technical problem of limiting the sleeve 24.

[0037] The above solution also has the problem of inconvenient disassembly and separation of the filter plate 31 and filter cotton 32, such as... Figure 4 As shown: In this scheme, the diameter of the filter plate 31 is adapted to the inner wall of the filter cylinder 21, and the diameter of the filter cotton 32 is smaller than the diameter of the filter plate 31. Since the diameter of the filter plate 31 is adapted to the inner wall of the filter cylinder 21, there is a gap between the filter plate 31 and the filter cylinder 21 during use, which improves the filtration effect. Furthermore, under the action of the filter cotton 32, the liquid in the filter cylinder 21 is filtered.

[0038] The above solution also has the problem that the filter element assembly 3 will pop out of the filter cylinder 21 after penetrating the limiting sleeve 24. Figure 3 As shown: In this solution, a cross 241 is embedded in the limiting sleeve 24. Under the action of the cross 241, the top of the limiting seat 22 is limited to prevent the limiting seat 22 from being misaligned after passing through the limiting sleeve 24, which would reduce the filtration effect.

[0039] Working principle:

[0040] like Figure 1-4As shown, first place the spring 33 inside the filter cylinder 21, then place the two filter element plates 31 and the filter cotton 32 above the spring 33. Subsequently, place the filter element assembly 3 inside the filter cylinder 21 in the above order. Since the spring 33 has a certain elasticity, when installing the limiting sleeve 24, it needs to be pressed down and then the locking block 242 and the locking groove 211 are locked together for mutual locking. After locking, rotate the three limiting rotating seats 212 into the locking groove 211, and magnetically attract the limiting plate 23 to the top of the limiting seat 22 through the magnetic attraction point 231 to limit the limiting rotating seat 212. After fixing, insert the filter valve 1 from the top and lock it in a staggered manner. After locking, screw the upper cap 11 onto the top opening of the filter valve 1. The installation is complete. Fix the filter valve 1 in the designated position using the mounting plate 12.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
