Description

Technical Field

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

[0002] A precision filter element refers to the filter cartridge within a precision filter. The primary function of a filter element, and indeed the core principle of a filter, is to purify raw materials and facilitate their reuse. Filter elements are commonly used in filtration industries such as oil filtration, water filtration, and air filtration. They remove small amounts of impurities from the filter medium, protecting the equipment and ensuring air cleanliness.

[0003] In existing technologies, since the filter element needs to be fixed inside the filter, the filter element is generally fixed in position by a threaded connection and sealed by a sealing ring. After long-term use, it is easy to break and leak. Furthermore, during filtration, the concentrated entry of the filter medium into the precision filter element can easily damage the inner wall of the filter element. Therefore, we propose a precision filter element to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a precision filter element.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A rotating sleeve is fixedly connected to the top of the base plate. A circular block is rotatably connected to the inner wall of the rotating sleeve. A threaded rod is fixedly connected to the outer wall of the circular block. A top plate is threadedly connected to the outer wall of the threaded rod. Multiple annular sleeves are fixedly connected to the outer walls of both the base plate and the top plate. An annular sealing gasket is slidably connected to the inner wall of the annular sleeve. A filter element body is slidably connected to the outer wall of the annular sealing gasket. A mesh sleeve is fixedly fitted to the outer wall of the filter element body. Two annular blocks are fixedly fitted to the outer wall of the mesh sleeve. An annular rubber pad is fixedly connected to the outer wall of each of the two annular blocks. An annular groove is formed on the outer wall of the annular sleeve. The inner wall of the annular groove is pressed against the outer wall of the annular rubber pad. A buffer mechanism is provided at the top of the top plate.

[0007] Preferably, the buffer mechanism includes a threaded sleeve, a threaded groove is provided on the top of the top plate, the inner wall of the threaded groove is threaded with a threaded sleeve, a sliding sleeve is fixedly connected to the top of the threaded sleeve, a T-shaped post is slidably connected to the inner wall of the sliding sleeve, a spring is fixedly connected to the bottom of the T-shaped post, and a semi-circular buffer plate is fixedly connected to the top of the T-shaped post. The T-shaped post and the spring are used to support and buffer the semi-circular buffer plate.

[0008] Preferably, the top of the precision filter housing is threadedly connected to a housing cover, and a flow pipe is fixedly connected to the top of the housing cover.

[0009] Preferably, the outer walls of both the bottom plate and the top plate are provided with multiple inlet holes, which correspond to the two ends of the filter element body.

[0010] Preferably, the bottom of the spring is fixedly connected to the inner wall of the sliding sleeve, and the spring causes the T-shaped column to buffer.

[0011] Preferably, the outer wall of the precision filter housing is fixedly connected to a discharge pipe and a connecting pipe, and a valve is installed on the outer wall of the discharge pipe.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This design forms a double-layer seal by setting a base plate, rotating sleeve, threaded rod, top plate, annular sleeve, annular sealing gasket, annular block, annular rubber gasket, and inlet hole, which improves the sealing effect and prevents leakage of filter media.

[0019] Depend on Figures 1-3As shown, a precision filter element is disclosed, comprising a precision filter housing 1, a housing cover 2 threadedly connected to the top of the precision filter housing 1, a flow tube 3 fixedly connected to the top of the housing cover 2, a base plate 4 fixedly connected inside the precision filter housing 1, a rotating sleeve 5 fixedly connected to the top of the base plate 4, a circular block rotatably connected to the inner wall of the rotating sleeve 5, a threaded rod 6 fixedly connected to the outer wall of the circular block, and a top plate 7 threadedly connected to the outer wall of the threaded rod 6. Rotating the threaded rod 6 causes the top plate 7 to move, and during the rotation, the top plate 7 is held by hand to prevent it from rotating on its own.

[0020] Multiple entry holes 14 are provided on the outer walls of both the bottom plate 4 and the top plate 7. Multiple annular sleeves 8 are fixedly connected to the outer walls of both the bottom plate 4 and the top plate 7. Annular sealing gaskets 9 are slidably connected to the inner walls of the annular sleeves 8. Both ends of the filter element body 12 slide into the annular sleeves 8 to limit their movement and form a preliminary seal through the annular sealing gaskets 9.

[0021] The outer wall of the annular sealing gasket 9 is slidably connected to the filter element body 12. The outer wall of the filter element body 12 is fixedly fitted with a mesh sleeve 13. The outer wall of the mesh sleeve 13 is fixedly fitted with two annular blocks 10. The outer walls of the two annular blocks 10 are fixedly connected with annular rubber pads 11. The annular blocks 10 contact the outer wall of the annular sleeve 8 to form a seal. When the annular rubber pads 11 slide into the annular groove, a seal is formed again to prevent leakage of the filter medium. The outer wall of the annular sleeve 8 has an annular groove. The inner wall of the annular groove is pressed against the outer wall of the annular rubber pads 11. The top of the top plate 7 is provided with a buffer mechanism.

[0022] Depend on Figures 2-4 As shown, the buffer mechanism includes a threaded sleeve 15. A threaded groove is provided on the top of the top plate 7. The inner wall of the threaded groove is threaded with the threaded sleeve 15. A sliding sleeve 16 is fixedly connected to the top of the threaded sleeve 15. The threaded sleeve 15 protects the top of the threaded rod 6. A T-shaped post 18 is slidably connected to the inner wall of the sliding sleeve 16. A spring 17 is fixedly connected to the bottom of the T-shaped post 18. The spring 17 buffers the T-shaped post 18.

[0023] The bottom of the spring 17 is fixedly connected to the inner wall of the sliding sleeve 16, and the top of the T-shaped column 18 is fixedly connected to the semi-circular buffer plate 19. The filter medium impacts the outer surface of the semi-circular buffer plate 19 and diffuses through the semi-circular buffer plate 19. The outer wall of the precision filter housing 1 is fixedly connected to the discharge pipe 20 and the connecting pipe 21. A valve is installed on the outer wall of the discharge pipe 20.

[0024] Working principle: In use, the bottom of the filter element body 12 is placed inside the annular sleeve 8, and the top plate 7 is fitted onto the threaded rod 6. Rotating the threaded rod 6 moves the top plate 7, aligning the annular sleeve 8 on the top plate 7 with the top of the filter element body 12. When both ends of the filter element body 12 are pressed against the outer wall of the annular sealing gasket 9, the annular rubber gasket 11 slides into the annular groove, forming a double seal, improving the sealing effect and preventing leakage of the filter medium. The filter medium enters the precision filter housing 1 through the flow pipe 3, impacts the outer surface of the semi-circular buffer plate 19, diffuses through the semi-circular buffer plate 19, and is buffered by the spring 17 and the T-shaped column 18, reducing the impact force and preventing the filter medium from concentrating into the filter element body 12. It enters the filter element body 12 through the inlet hole 14 on the top plate 7 for filtration. The filtered medium is discharged from the outlet pipe 20, and impurities enter the bottom of the inner wall of the precision filter housing 1 and are discharged from the connecting pipe 21.

Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
