[0017] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0018] The first implementation method: Figure 1-2 A hydraulic pump station oil tank is shown, comprising a base 1, the top of the base 1 is fixedly connected to an oil tank 2, the inner wall of the bottom end of the oil tank 2 is provided with a plurality of evenly distributed sedimentation chambers 3, the outer wall of the bottom end of the oil tank 2 is provided with a plurality of evenly distributed refrigeration chambers 4, the plurality of sedimentation chambers 3 and the plurality of refrigeration chambers 4 are distributed at intervals, the side wall at one end of the oil tank 2 is fixedly connected to an inlet pipe 201, the side wall at the other end of the oil tank 2 is fixedly connected to an outlet pipe 202, the top of the oil tank 2 is provided with a slide groove 203, one end of the base 1 is fixedly connected to a liquid nitrogen bottle 5, the other end of the base 1 is fixedly connected to a liquid nitrogen bottle 5, and the bottom end of the base 1 is fixedly connected to a liquid nitrogen bottle 5. One end is fixedly connected to a heat machine 6, the output end of the liquid nitrogen bottle 5 is fixedly connected to a nitrogen delivery pipe 501, the output end of the heat machine 6 is fixedly connected to a gas delivery pipe 601, a transfer pipe 7 is fixedly connected between the nitrogen delivery pipe 501 and the gas delivery pipe 601, one end of the transfer pipe 7 is fixedly connected to a plurality of dual-purpose nozzles 8, and the plurality of dual-purpose nozzles 8 are respectively located inside a plurality of refrigeration chambers 4, one end of the transfer pipe 7 close to the nitrogen delivery pipe 501 is fixedly connected to a left switch valve 9, and one end of the transfer pipe 7 close to the gas delivery pipe 601 is fixedly connected to a right switch valve 10.

[0019] The hydraulic oil enters the interior of the base 1 through the inlet pipe 201 and is discharged outward through the outlet pipe 202. During the movement of the hydraulic oil, impurities are deposited in the interior of multiple sedimentation chambers 3. When there are too many impurities in the sedimentation chamber 3, the left switch valve 9 is opened, the right switch valve 10 is closed, and liquid nitrogen is released into the interior of the refrigeration chamber 4 through the liquid nitrogen bottle 5 and the dual-purpose nozzle 8. At this time, the hydraulic oil in the sedimentation chamber 3 is frozen together with the impurities. The density of the impurities decreases after freezing. Then the left switch valve 9 is closed, the right switch valve 10 is opened, and hot air is briefly discharged into the refrigeration chamber 4 through the hot air machine 6 and the dual-purpose nozzle 8 to melt the frozen impurities close to the wall of the sedimentation chamber 3. At this time, the frozen impurities are separated from the sedimentation chamber 3, and the frozen impurities are picked up to complete the purification of the hydraulic oil. Through the above-mentioned setting, compared with removing impurities in the form of a filter, the impurities can be removed without stopping the machine, thereby improving the working efficiency of the equipment.

[0020] The second implementation method: Figure 1-8 A hydraulic pump station oil tank is shown. Different from the first embodiment, an electric telescopic rod 12 is slidably connected inside the slide 203, and a connecting block 15 is fixedly connected to the side wall of the electric telescopic rod 12. Two vertical plates 13 are fixedly connected to the top of the oil tank 2. The two vertical plates 13 are respectively located on both sides of the slide 203. A screw rod 14 is rotatably connected between the two vertical plates 13. The screw rod 14 passes through the connecting block 15 and is threadedly connected thereto. A motor 16 is fixedly connected to the side wall of one of the vertical plates 13, and the output end of the motor 16 is fixedly connected to one end of the screw rod 14. The telescopic end of the electric telescopic rod 12 is fixedly connected to an isolation tube 11 matching the sedimentation chamber 3, and a sealing ring 1101 is fixedly connected to the top of the isolation tube 11. The bottom end of the dual-purpose nozzle 8 is fixedly connected to a bottom valve 801.

[0021] Since the temperature of the hydraulic oil is relatively high, the freezing efficiency of impurities inside the sedimentation chamber 3 is low. Through the above-mentioned arrangement, when cleaning one of the sedimentation chambers 3, the heat generator 6 can be started to drive the electric telescopic rod 12 to move to the top of the sedimentation chamber 3, and the electric telescopic rod 12 can be started to drive the isolation tube 11 to move inside the sedimentation chamber 3. At this time, the sedimentation chamber 3 can isolate the impurities from the hydraulic oil flowing outside, and then open the left switch valve 9 and the corresponding bottom valve 801, and the impurities between the sedimentation chamber 3 and the isolation tube 11 are frozen, which improves the freezing efficiency of the impurities and reduces the waste of cold energy.

[0022] A cooling chamber 19 is provided inside the oil tank 2 near the bottom of the inlet pipe 201, and a cold plate 1901 is fixedly connected to the top of the cooling chamber 19. One end of the nitrogen delivery pipe 501 is fixedly connected to a liquid nitrogen branch pipe 20, and one end of the liquid nitrogen branch pipe 20 extends to the inside of the cooling chamber 19, and the other end of the liquid nitrogen branch pipe 20 is fixedly connected to a secondary valve 2001.

[0023] Since the temperature of the hydraulic oil is relatively high, the frozen impurities will dissolve faster during the floating process, causing the impurities to melt again and fall into the hydraulic oil. Through the above configuration, before freezing the impurities, the auxiliary valve 2001 is opened to release liquid nitrogen into the cooling chamber 19 through the liquid nitrogen branch pipe 20. At this time, the temperature of the cold plate 1901 is reduced, which has a cooling effect on the hydraulic oil. When the temperature of the hydraulic oil drops to 0-10 degrees Celsius, the impurities are frozen again. At this time, the frozen impurities can reduce the amount of impurities dissolved during the floating process, thereby improving the removal effect of impurities.

[0024] A connecting plate 22 is fixedly connected to the inner wall of the oil tank 2 near the inlet pipe 201, and a drain groove 21 is provided on the side wall of the oil tank 2 near the connecting plate 22. A hot branch pipe 17 is fixedly connected to one end of the gas supply pipe 601, and one end of the hot branch pipe 17 extends to the interior of the oil tank 2. An air valve 1701 is fixedly connected to the other end of the hot branch pipe 17. A hose 18 is fixedly connected between one end of the hot branch pipe 17 located inside the oil tank 2 and the top end of the isolation pipe 11, and an exhaust pipe 1102 is provided at the top end of the isolation pipe 11.

[0025] The impurities between the sedimentation chamber 3 and the isolation tube 11 will also adhere to the surface of the isolation tube 11 after being frozen. The electric telescopic rod 12 will drive the isolation tube 11 to rise, and at the same time, it will drive the frozen impurities to rise. Then the isolation tube 11 moves above the support plate 22, and the air valve 1701 and the heat generator 6 are opened to blow hot air into the interior of the isolation tube 11. After the temperature of the isolation tube 11 rises, the frozen impurities attached to its surface melt and fall onto the connecting plate 22. Through the above arrangement, the transfer of frozen impurities can be completed.

[0026] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
