The filter membrane is an important component material in the bearing cleanliness test. After the test bearing is thoroughly cleaned with the cleaning liquid, the collected cleaning solution is filtered through the filter membrane. The membrane pores of the filter membrane filter the solvent and retain other impurities in the solvent, thereby achieving the purpose of separating impurities. The filtered filter membrane is then placed in a weighing bottle for drying and weighing, and the cleanliness of the bearing is assessed by detecting the weight of the filtered impurities.

[0003] In the bearing cleanliness test, the filter membrane is a key filter element, and its integrity directly affects the accuracy of the test results. In the prior art, the filter membrane is usually placed directly inside the filter assembly, and it is necessary to use tools such as tweezers to remove it. This process is easy to cause damage to the filter membrane due to its fragility, and the sharp edges of the tweezers increase the risk of damage. In addition, when the filter membrane is taken out at an angle, impurities attached to it are easy to fall off, thereby affecting the accuracy of the experimental data. Therefore, it is particularly important to design a carrier that can easily and safely remove the filter membrane. Utility Model Content

One end of the push rod 8 located outside the sealing frame 5 is fixedly connected with a push ring 6. The push ring 6 is located below the sealing frame 5, and the push ring 6 is also movably sleeved on the outside of the bottom end of the filter cartridge 1. The filter membrane body 4 of this structure is placed inside the filter membrane ring 3. When the cleaning solution introduced into the filter cartridge 1 is filtered and needs to be taken out, the push ring 6 can be pushed upward on the outside of the bottom end of the filter cartridge 1 to drive the two push rods 8 to push up. When the push rod 8 is pushed up, the bottom end part of the push block 7 is simultaneously driven to push up inside the sealing frame 5. When the push block 7 is pushed up, its top part can push the support ring 2 together with the filter membrane ring 3 from the edge of the filter cartridge 1, and the filter membrane ring 3 can also be conveniently removed horizontally from the support ring 2, thereby realizing the effect of rapid and non-destructive removal of the filter membrane body 4, reducing the falling of impurities caused by the tilting operation, which is conducive to improving the detection efficiency and accuracy. Solid blocks 10 are provided on both the front and rear sides of the outer wall of the bottom end of the filter cartridge 1, and a spring member 11 is connected between the corresponding positions of the solid block 10 and the push ring 6. When the push ring 6 of this structure is pushed upward, it will produce a corresponding force on the spring member 11 with the cooperation of the solid block 10. In this way, when the filter membrane body 4 is replaced in the filter membrane ring 3, the push ring 6 can be released and the support ring 2 together with the filter membrane ring 3 can be quickly recovered into the filter cartridge 1 under the action of the spring member 11, which is more convenient to use. The interior of the sealing frame 5 is provided with a guide block 9 with an inclined structure, and the edges of the guide block 9 are welded and fixed to the inner wall of the sealing frame 5. The push rod 8 is slidably connected with the guide block 9. The guide block 9 of this structure can guide a small amount of cleaning solution flowing from the filter cartridge 1 into the sealing frame 5, thereby preventing the cleaning solution filtered by the filter membrane body 4 from flowing into the interior of the sealing frame 5 from the vertical opening on the filter cartridge 1. Arc-shaped inserts 12 are welded and fixed on both sides of the bottom of the filter membrane ring 3, and arc-shaped embedding grooves that match the structure of the arc-shaped inserts 12 are provided on both sides of the top of the support ring 2. The filter membrane ring 3 of this structure can be embedded in the arc-shaped embedding groove on the top of the support ring 2 through the arc-shaped insert 12, thereby realizing the effect of rapid detachment of the filter membrane ring 3 from the support ring 2.It avoids using sharp tools to directly contact the filter membrane body 4, effectively reducing the risk of damage to the filter membrane body 4. A rectangular opening 13 is provided in the middle of the front side of the filter membrane ring 3, and a concave opening 14 is provided in the middle of the front side of the support ring 2 at a position corresponding to the rectangular opening 13. The rectangular opening 13 and the concave opening 14 of this structure can cooperate with each other to allow tools to extend into and clamp the filter membrane ring 3. The horizontal removal of the filter membrane ring 3 effectively reduces the loss of impurities and improves the accuracy of the test results.

[0019] Working principle: When using the filter membrane carrier for bearing cleanliness detection, first, when the filter membrane body 4 needs to be taken out after filtering the cleaning solution introduced into the filter cartridge 1 inside the filter membrane ring 3, first open the end cover at the top of the filter cartridge 1, and then push the push ring 6 upward on the outside of the bottom end of the filter cartridge 1. When the push ring 6 is subjected to force, it will drive the two push rods 8 to push up. When the push rods 8 are pushed up, they will simultaneously drive the bottom end of the push block 7 to push up inside the sealing frame 5. At this time, the push block 7 can pass through the vertical opening on the filter cartridge 1 so that the top part pushes the bottom of the support ring 2. When the support ring 2 is subjected to force, it will drive the filter membrane ring 3 to move upward at the upper end inside the filter cartridge 1 until the support ring 2 together with the filter membrane ring 3 is pushed out from the edge of the filter cartridge 1, and then the operator reaches into the rectangular opening 13 and the concave opening 14 with the help of tweezers, and then clamps the filter membrane ring 3. The filter membrane ring 3 can be quickly removed when the arc-shaped embedding block 12 is disengaged from the arc-shaped embedding groove on the top of the supporting ring 2, and then the new filter membrane body 4 is placed inside the filter membrane ring 3. Because the push ring 6 will squeeze the spring member 11 with the cooperation of the solid block 10 when it is pushed upward, when the filter membrane body 4 is replaced in the filter membrane ring 3, the push ring 6 can be released and the supporting ring 2 together with the filter membrane ring 3 can be quickly recovered into the filter cartridge 1 under the action of the spring member 11 for reuse, thereby completing a series of work.
