[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 This is a schematic diagram of the overall structure of the hydraulic system pump station oil treatment equipment with multiple filtration and purification according to this utility model. Figure 2 This is a schematic diagram of the quick replacement mechanism of the hydraulic system pump station oil treatment equipment with multiple filtration and purification according to this utility model. Figure 3 This is a schematic diagram of the sliding pipe structure of the hydraulic system pump station oil treatment equipment with multiple filtration and purification according to this utility model. Figure 4 This utility model provides a schematic diagram of a conical annular groove structure for a hydraulic system pump station oil treatment device with multiple filtration and purification. The device includes: a housing 1, on which a hydraulic pump 2 is fixedly mounted; an oil delivery pipe 3 is provided on the hydraulic pump 2; an oil delivery pipe 4 is fixedly connected through the housing 1; a lower outer ring 5 is fixedly sleeved on the outer wall of the second oil delivery pipe 4; an upper outer ring 6 is fixedly sleeved on the bottom end of the first oil delivery pipe 3; and a rotating shaft 7 is rotatably connected to the top surface of the housing 1, with two quick-change mechanisms on the shaft 7.

[0023] The quick-change mechanism includes a connecting arm 8, which is fixedly connected to a rotating shaft 7. An outer tube 9 is fixedly connected to the other end of the connecting arm 8. Bottom rings 10 are fixedly connected to both the upper and lower ends of the outer tube 9. A slide tube 11 is slidably connected to the inner wall of the outer tube 9. A top ring 12 is fixedly sleeved on the outer wall of the slide tube 11. A spring 13 is fixedly connected to the bottom surface of the top ring 12. The bottom end of the spring 13 is fixedly connected to the top surface of the bottom ring 10. An adjustment component is provided on the outer tube 9.

[0024] like Figure 3As shown, the adjustment assembly includes four telescopic rods 14, each of which is fixedly connected to the bottom surface of the top ring 12. The bottom ends of the four telescopic rods 14 are fixedly connected to a fixing ring 15. An internally threaded rotating ring 16 is rotatably installed at the bottom of the fixing ring 15. The inner wall of the internally threaded rotating ring 16 is threadedly connected to the outer wall of the outer tube 9. The bottom ring 10 has sliding holes corresponding to the four telescopic rods 14.

[0025] By adjusting the component settings, rotating the internal threaded swivel 16 can drive the top ring 12 to descend, thereby allowing the quick-change mechanism to smoothly enter between the lower outer ring 5 and the upper outer ring 6 when rotating the shaft 7.

[0026] like Figure 3 As shown, a limiting ring 17 is fixedly connected to the outer wall of the slide tube 11, and an annular groove corresponding to the limiting ring 17 is opened on the inner wall of the outer tube 9.

[0027] By setting the limiting ring 17, the position of the slide tube 11 can be limited to prevent the slide tube 11 from moving out of the outer tube 9.

[0028] like Figure 3 As shown, the slide tube 11 is provided with multiple filter elements 18, and the top surface of the top ring 12 is fixedly connected with a guide ring 19;

[0029] The multiple filter elements 18 enable multiple filtration processes for the oil. The guide rings 19 prevent jamming when the rotating shaft 7 drives the quick-change mechanism between the lower outer ring 5 and the upper outer ring 6, with the two guide rings 19 contacting the top surface of the lower outer ring 5 and the bottom surface of the upper outer ring 6 respectively.

[0030] like Figure 4 As shown, a push plate 20 is fixedly connected to the rotating shaft 7, and two sealing plates 21, which correspond to the positions of the lower outer ring 5 and the upper outer ring 6 respectively, are fixedly sleeved on the outer wall of the rotating shaft 7.

[0031] The push plate 20 allows the operator to easily rotate the shaft 7. The sealing plate 21 allows the two outer tubes 9 to be rotated and moved to the corresponding lower outer ring 5 and upper outer ring 6 to seal them and prevent oil from overflowing.

[0032] like Figure 4 As shown, both the lower outer ring 5 and the upper outer ring 6 are provided with conical annular grooves 22, and the size of the conical annular grooves 22 is adapted to the size of the guide ring 19;

[0033] The conical annular groove 22, in conjunction with the spring 13, can improve the sealing performance of the two slide pipes 11 with oil pipe 3 and oil pipe 4 respectively.

[0034] The working principle of the hydraulic system pump station oil treatment equipment with multiple filtration and purification provided by this utility model is as follows:

[0035] During use, after prolonged operation of the hydraulic pump 2, the multiple filter element 18 needs to be replaced. At this time, the operator shuts off the hydraulic pump 2 and closes the corresponding valves to prevent oil spillage during the replacement of the multiple filter element 18. Then, the two internally threaded rotating rings 16 on the working outer pipe 9 are rotated, causing the top ring 12 to descend, thereby reducing the pressure of the spring 13 on the top ring 12. This causes the guide ring 19 to begin separating on the conical ring groove 22. Then, the connecting arm 8 is rotated via the push plate 20, causing the working outer pipe 9 to begin leaving the space between the lower outer ring 5 and the upper outer ring 6. Simultaneously, the idle outer pipe 9 begins to enter the space between the lower outer ring 5 and the upper outer ring 6. When the tube has moved halfway, rotate the two internal threaded rings 16 on the idle outer tube 9 to move the two top rings 12 up and down respectively, thus disengaging the restriction on the spring 13 and allowing the pressure of the spring 13 to be fully applied to the top rings 12. Then, increase the force of rotating the shaft 7 to move the idle outer tube 9 between the lower outer ring 5 and the upper outer ring 6. The pressure of the spring 13 will press the guide ring 19 tightly into the conical ring groove 22 to enhance the sealing. At this time, the previously working outer tube 9 will also be removed, and then the multiple filter element 18 inside the outer tube 9 can be cleaned and replaced. This facilitates the replacement and cleaning of the multiple filter element 18 and also reduces the downtime of the hydraulic pump 2.
