[0033] Please refer to Figures 1-7 As shown, a technical solution of an efficient wire mesh filter provided by this utility model: An efficient wire mesh filter includes a positioning buckle 1. A filter bottle body 2 is fixedly installed inside the positioning buckle 1. A liquid inlet 3 is provided on one side of the filter bottle body 2. A flow splitting component 4 is installed inside the filter bottle body 2, and a filtering component 5 is also installed inside the filter bottle body 2. The flow splitting component 4 includes a partition plate 401 and a telescopic rod 405. The partition plate 401 is installed on the inner wall of the filter bottle body 2 inside the liquid inlet 3. A piston 402 is movably arranged between the partition plate 401 and the inner wall of the filter bottle body 2. The length of the piston 402 is greater than the aperture of the liquid inlet 3. The up and down movement of the piston 402 controls the flow of the liquid in the liquid inlet 3 above or below the piston 402. A chute 403 is centrally provided on the side of the partition plate 401 away from the liquid inlet 3. Liquid discharge grooves 404 are provided on the upper and lower sides of the partition plate 401 at the chute 403. One end of the telescopic rod 405 passes through the chute 403 and is rotatably connected to the side wall of the piston 402, and the other end of the telescopic rod 405 is rotatably connected to the inner wall of the filter bottle body 2. The filtering component 5 pushes the telescopic rod 405 to drive the piston 402 to move up and down inside the partition plate 401.

[0034] When the filter works normally, the filtering component 5 is installed at one end of the filter bottle body 2. The end of the filtering component 5 abuts against the telescopic rod 405 to position the piston 402, ensuring that the liquid to be filtered in the liquid inlet 3 flows into the filtering component 5. When the filter screen of the filtering component 5 is blocked and needs to be taken out for replacement or cleaning, a clean filtering component 5 is inserted from the other end of the filter bottle body 2. Under the action of the two filtering components 5 on both sides, the piston 402 is pushed to the middle of the partition plate 401 to block the liquid inlet 3. Subsequently, the filtering component 5 that needs to be replaced is taken out. The telescopic rod 405 drives the piston 402 to move to the other side under the push of the new filtering component 5. At this time, the filter can continue to filter.

[0035] The filter component 5 includes a limit ring 501, a filter sleeve 503 and an installation box 506. The limit rings 501 are symmetrically and fixedly installed on the upper and lower sides of the chute 403 inside the filter bottle body 2, and first sealing rings 502 are installed at the ring openings of the limit rings 501. The filter sleeve 503 is installed at any one end of the filter bottle body 2. Filter meshes 504 are provided on the barrel wall of the filter sleeve 503, and second sealing rings 505 are installed at both ends of the filter bottle body 2. The installation box 506 is installed at the top end inside the filter sleeve 503. A spring 507 is installed inside the installation box 506. One end of the spring 507 is installed with a push rod 508, and the push rod 508 is slidably connected to the through holes at the top ends of the installation box 506 and the filter sleeve 503. The first sealing ring 502 and the second sealing ring 505 ensure that the fluid can only flow into the filter sleeve 503 through the filter meshes 504 after being discharged from the drain groove 404, and no leakage will occur. The pressure of the filter sleeve 503 on the filter bottle body 2 can increase the sealing performance of the first sealing ring 502 and the second sealing ring 505.

[0036] When the filter is working properly, the fluid to be filtered enters from the liquid inlet 3, passes through the piston 402 and then through the drain groove 404, and finally is filtered by the filter meshes 504 and discharged from the drain port at the end of the filter sleeve 503. When replacing the filter component 5, a new filter sleeve 503 is inserted and fixed from one end of the filter bottle body 2. At this time, the push rods 508 on both sides of the telescopic rod 405 push the telescopic rod 405 to a position close to the horizontal under the action of the spring 507, so that the piston 402 is pushed to the middle of the partition plate 401, blocking the liquid inlet 3. Finally, the filter sleeve 503 on the other side can be taken out. Under the action of the push rod 508 and the spring 507, the telescopic rod 405 is pushed to a new position to ensure that the fluid flows to the new filter sleeve 503. The telescopic rod 405 is composed of a main rod and a sub-rod slidably connected inside the main rod. When the telescopic rod 405 rotates up and down, the sub-rod slides inside the main rod to ensure the continuity and stability of the movement.

[0037] A positioning groove 201 is provided at the port of the filter bottle body 2, and a positioning block 202 matching the positioning groove 201 is installed at the end of the filter sleeve 503. When installing the filter sleeve 503, the positioning block 202 is inserted along the positioning groove 201, which can accurately control the insertion position and angle of the filter sleeve 503.

[0038] The installation box 506 is installed on the side of the filter sleeve 503 adjacent to the liquid inlet 3. This installation position can increase the force arm, and it is more labor-saving for the push rod 508 to push the telescopic rod 405.

[0039] The end of the filter sleeve 503 and the filter bottle body 2 are connected by a connection buckle under pressure. The connection buckle is convenient for connection and can increase the connection pressure between the filter sleeve 503 and the filter bottle body 2 to ensure the sealing performance of the second sealing ring 505.

[0040] The working principle of the utility model is as follows:

[0041] When an efficient wire mesh filter of this embodiment is working normally, the filtering sleeve 503 is press-fitted at one end of the filtering bottle body 2. The end of the ejector rod 508 presses against the telescopic rod 405 under the action of the spring 507 to position the piston 402, ensuring that the liquid to be filtered in the liquid inlet 3 flows into the corresponding filtering sleeve 503. Subsequently, the fluid to be filtered enters from the liquid inlet 3, passes through the piston 402, then passes through the drain groove 404, and finally is filtered by the filter wire mesh 504 and discharged from the drain port at the end of the filtering sleeve 503. When the filter wire mesh 504 of the filtering sleeve 503 is blocked and needs to be taken out for replacement or cleaning. As Figure 4 shown, the clean filtering sleeve 503 is inserted from the other end of the filtering bottle body 2. Under the action of the same thrust applied by the two ejector rods 508 to the telescopic rod 405, the piston 402 is pushed to near the middle of the partition plate 401 to block the liquid inlet 3. Subsequently, the filtering sleeve 503 that needs to be replaced is taken out. The telescopic rod 405 drives the piston 402 to move to the other side under the push of the new ejector rod 508. At this time, the filter can continue to filter. The utility model has a simple structure and a reasonable design. Through the flow splitting component 4, the filtering sleeve 503 can be quickly replaced in a very short time. The operation is simple and there is no need to open the filtering bottle body 2. And the filtering path of the fluid is set to two paths. The flow direction of the fluid is precisely controlled during the replacement process of the filtering sleeve 503 to avoid fluid leakage, significantly improving the working efficiency of the filter and better meeting the actual production and use requirements of current enterprises. At the same time, through the filtering component 5, the position of the piston 402 is adjusted by the push of the ejector rod 508. The adjustment process does not require the intervention of staff and can be actively adjusted according to the position of the filtering sleeve 503, further improving the replacement efficiency and working efficiency of the filter element of the filter.

[0042] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art of this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the utility model and do not limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the utility model claimed.
