[0002] Hydraulic pump stations typically consist of hydraulic pumps, oil tanks, valve groups, and return oil lines. They are common components of hydraulic systems, providing hydraulic energy to drive various actuators within the system. During normal use, they require a filtration device for protection. The return oil filtration device for hydraulic pump stations described in patent application CN 221195611 U, which uses a check valve and filter screen installed in a guide pipe to switch the flow direction for filtration, cannot be directly installed and positioned on the circulation loop. This makes rapid switching control inconvenient, hinders disassembly and maintenance, is prone to leakage, and has poor adaptability. Therefore, we propose a control device for self-filtering switching in hydraulic pump stations. Summary of the Invention

Detailed Implementation
[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0016] like Figure 1-5 As shown, this utility model is a control device for self-filtration switching in a hydraulic oil station. It includes a hydraulic oil tank 1, with a circulation pump 11 fixedly installed on one side of the tank. Hydraulic oil is stored inside the tank and pumped out via the circulation pump 11, then delivered to the equipment using the oil via an outlet pipe 12. A return pipe 13 returns the hydraulic oil, creating a circulation system for convenient combined use. The outlet of the circulation pump 11 is fixedly connected to the outlet pipe 12, and the return pipe 13 is fixedly installed on the other side of the tank. A square pipe 14 is fixedly connected between the outlet pipe 12 and the return pipe 13, allowing for positioning at both ends of the square pipe 14. During normal circulation, they do not interfere with each other. When self-filtration is required, switching can be performed, thereby shortening the filtration process, improving filtration efficiency, and providing convenience and high efficiency. A mounting hole 15 is provided on one side of the square tube 14. A filter cylinder 16 is threaded onto one end of the mounting hole 15, allowing hydraulic oil to be passed into the filter cylinder 16 for filtration. Due to the shortened filtration path, the resistance of the hydraulic oil passing through the filter is reduced, thereby improving the filtration efficiency. A connecting pipe 17 is fixedly welded to one side of the return oil pipe 13. A docking cylinder 18 is fixedly connected to the end of the connecting pipe 17. The docking cylinder 18 is threaded to the front end of the filter cylinder 16. Both ends of the square tube 14 are fixedly connected to a partition plate 2. The partition plate 2 has a connecting hole 21 inside. A switching component 22 is provided on the side of the partition plate 2. The switching component 22 is located on the inner side of the oil outlet pipe 12 and the oil return pipe 13. By installing the switching component 22, the direction of the flow channel can be switched, thereby changing the circulation direction for filtration. Furthermore, the switching assembly 22 includes an adjusting rod 23 and right-angle sealing plates 24 fixedly connected to both ends of the adjusting rod 23. The adjusting rod 23 is slidably connected to the inside of the communicating hole 21, and the right-angle sealing plates 24 are slidably installed inside the square tube 14. Furthermore, a right-angle sealing gasket 25 is fixedly attached to the surface of the right-angle sealing plate 24, and the right-angle sealing gasket 25 pushes into the inner wall surface of the square tube 14; Furthermore, the right-angle sealing plate 24 is located on one side of the oil outlet pipe 12 and the oil return pipe 13, and is connected to the side of the partition plate 2. The right-angle sealing plate 24 is installed by adjusting the rod 23, and can be combined and positioned at both ends inside the square tube 14, and can be adjusted and used synchronously. In practical use, the right-angle sealing plate 24 presses the right-angle sealing gasket 25 onto the partition plate 2, which can press and seal the connecting hole 21 to prevent leakage. This allows hydraulic oil to be normally delivered through the oil outlet pipe 12, while returning from the oil return pipe 13 on the other side. Some hydraulic oil can enter the filter cartridge 16 for filtration, which is beneficial for normal use. When switching and adjustment are required, the two right-angle sealing plates 24 can be moved by the adjusting rod 23 to open the connecting hole 21 and close the oil outlet pipe 12 and the oil return pipe 13. This allows the hydraulic oil to be directly introduced into the square pipe 14 and forced to return to the oil tank through the filter cartridge 16 and the connecting pipe 17. This allows for linear self-circulation filtration, greatly shortens the stroke, effectively improves filtration efficiency, and facilitates maintenance and use. Furthermore, one end of the switching component 22 is provided with an adjustment component 3. The adjustment component 3 includes a sealing baffle 31 and a threaded rod 32 rotatably mounted on the surface of the sealing baffle 31. The sealing baffle 31 is slidably connected to the inner front end of the square tube 14. By installing the adjustment component 3, the adjustment operation can be performed from the front end of the square tube 14, which is convenient and stable. Furthermore, the threaded rod 32 is threadedly installed at the front end of the square tube 14, and the rear side of the sealing baffle 31 is fixedly connected to the front end of the adjusting rod 23; Furthermore, the threaded rod 32 is provided with an adjusting head 33 at its front end. The adjusting head 33 is rotatably mounted on the front end of the square tube 14. By mounting the adjusting head 33 on the threaded rod 32, the thread can be rotated and adjusted for thread control, which is stable and efficient. In practical use, the adjusting head 33 can be manually rotated, which in turn rotates the threaded rod 32, pushing the sealing baffle 31 to slide and adjust its position. The sealing baffle 31 separates the threaded connection area from the oil circuit, preventing the threaded part from being contaminated or interfered with by oil, thus preventing leakage from the threaded position, which is convenient and stable. This row slides the adjusting rod 23 through the sealing baffle 31, which in turn slides the right-angle sealing plates 24 at both ends laterally to adjust the position. After adjustment, the threaded rod 32 is connected and positioned, which will not loosen, thus preventing internal leakage, improving the stability of switching filters, and making it highly adaptable.
[0017] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
