Description

Technical Field

[0001] The utility model relates to the field of oil-gas separation equipment, in particular to an oil-gas separation filter element component. Background Art

[0002] When the compressor is working, an oil-gas mixture will be produced. The oil-gas separation component can effectively separate the oil droplets and gas in the compressed air to ensure that the oil content in the output gas is reduced to below the specified standard;

[0003] By separating the oil, the compressed air is made purer and drier, and the adverse effects of the oil on subsequent equipment and process flows are reduced. The separated oil can be recovered and recycled, reducing the operating cost of the compressor and also reducing pollution to the environment. Nowadays, most separation technologies use filtration separation. After a long separation process, the internal filter element assembly is in contact with the oil-gas mixture for a long time, resulting in reduced conversion efficiency and requiring regular replacement and cleaning. When the filter element assembly is replaced and cleaned, the existing snap-fit ​​assembly directly connects the filter element to the outlet pipe, which can easily lead to a gap between them, making it not airtight, thereby reducing the filtration conversion efficiency.

[0004] Therefore, it is necessary to provide a new oil-gas separation filter element component to solve the above technical problems. Utility Model Content

[0026] In the specific implementation process, Figure 1-Figure 7 As shown, the utility model provides an oil-gas separation filter element assembly, comprising a housing component 1, an air outlet pipe 2 and a filter element assembly 3;

[0027] The filter element assembly 3 is located inside the shell member 1, one end of the air outlet pipe 2 is fixedly connected to the top of the shell member 1, the filter element assembly 3 and the shell member 1 are detachably connected through the clamping assembly 4, and the surfaces of the air outlet pipe 2 and the filter element assembly 3 are respectively provided with a plurality of first clamping grooves 44 and second clamping grooves 45 for the clamping assembly 4 to move. A limiting body 21 for limiting the clamping assembly 4 is fixedly provided on the surface of the air outlet pipe 2, and the limiting body 21 limits one side of the clamping body 43 to prevent the clamping body 43 from being separated due to excessive elastic force of the spring 42;

[0028] The clamping assembly 4 includes a clamping body 43, a spring 42 and a plurality of clamping beads 41. The plurality of clamping beads 41 are movably located inside a plurality of first clamping grooves 44 and a plurality of second clamping grooves 45. The clamping body 43 is sleeved on the surface of the air outlet pipe 2, and the inner side of the clamping body 43 is in contact with the clamping beads 41 and the surface of the air outlet pipe 2. One end of the spring 42 is fixedly connected to the top of the shell member 1, and the other end of the spring 42 is fixedly connected to one side of the clamping body 43. The side of the clamping body 43 away from the spring 42 is in contact with the surface of the limiting body 21, so that the clamping beads 41 roll inside the first clamping groove 44. When the second clamping groove 45 is aligned with the first clamping groove 44, the clamping body 43 can limit the plurality of clamping beads 41. The clamping body 43 will push the plurality of clamping beads 41 into the second clamping groove 45, and the filter tube 32 is clamped and limited to achieve rapid clamping.

[0029] The outer shell component 1 includes a top cover 11 and a shell 12. The bottom end of the top cover 11 and the top end of the shell 12 are fixedly connected by multiple bolts 17. A gasket 33 is fixedly provided at the bottom end of the top cover 11. The multiple bolts 17 can realize the fixed connection between the bottom end of the top cover 11 and the top end of the shell 12, thereby ensuring the airtightness inside the outer shell component 1, preventing the oil-gas mixture from spreading around and affecting other equipment, and preventing oil waste.

[0030] The filter element assembly 3 includes a filter cartridge 31 and a filter tube 32. Multiple second engaging grooves 45 are all located on the surface of the filter tube 32. The side of the gasket 33 away from the top cover 11 is in contact with the top of the filter cartridge 31. The filter tube 32 passes through the surface of the top cover 11, and the surface of the filter tube 32 is in contact with the inner wall of the outlet pipe 2. The gasket 33 can effectively prevent the oil and gas mixture from being discharged through the gap between the outlet pipe 2 and the filter tube 32 without being filtered.

[0031] An air intake pipe 15 is fixedly provided on the surface of the outer shell component 1. The air intake pipe 15 passes through the surface of the shell 12 and one end extends to the inside of the shell 12. An air intake valve 16 for controlling the gas flow is provided on the surface of the air intake pipe 15. The air intake valve 16 can automatically adjust the flow velocity of the oil-gas mixture entering the inside of the shell according to the pressure inside the outer shell component 1, thereby maintaining the pressure inside the outer shell component 1.

[0032] An oil return pipe 13 is fixedly provided at the bottom of the outer shell component 1, and an oil return valve 14 for controlling the flow of oil is provided on the surface of the oil return pipe 13. The oil return valve 14 is set to be in a closed state during the early filtering. When a certain volume of oil is collected, the oil return valve 14 will open and ensure the pressure inside the outer shell component 1, so that the filtered pure gas can be discharged smoothly.

[0033] The bottom of the filter cartridge 31 is arranged in a cone shape, and the filtered oil will flow downward along the surface of the cone and finally converge at the tip of the cone, so as to facilitate the centralized recovery of the oil.

[0034] The working principle provided by the utility model is as follows:

[0035] When installing the filter element assembly 3, first push the engaging body 43 toward the top plate. At this time, the engaging body 43 will squeeze and shrink the spring 42. When the engaging body 43 moves a certain distance and no longer contacts the multiple engaging beads 41, the engaging beads 41 lose their limit and can roll in the first engaging groove 44. Then, the filter cartridge 31 is pushed toward the air outlet pipe 2. The filter cartridge 31 drives the filter tube 32 to move. When the second engaging groove 45 on the surface of the filter tube 32 is aligned with the first engaging groove 44, When they are connected and the top end of the filter cartridge 31 and the bottom end of the gasket 33 are in contact with each other, the push on the locking body 43 is cancelled. At this time, the locking body 43 is restored to its initial state by the elastic force of the spring 42. The limiting body 21 limits the side of the locking body 43 away from the spring 42 to prevent the locking body 43 from being separated due to excessive elastic force of the spring 42. At this time, the locking body 43 contacts the surface of the locking bead 41 again to limit the locking bead 41. Through the coordinated operation of the above components, the filter element assembly 3 is finally installed.
