[0002] A hydraulic pump station fuel tank refers to a container used to store hydraulic oil in a hydraulic system. The main functions of the hydraulic fuel tank are as follows: filtering the oil. Usually, a filter or a filter screen is installed in the hydraulic fuel tank to filter impurities and pollutants in the hydraulic oil, maintain the cleanliness of the hydraulic oil, and extend the service life of the hydraulic system.

[0003] After the filter screen in the fuel tank has been used for a period of time, its own filtering effect will be lost. Especially in the case of a large amount of impurities, the filter needs to be replaced frequently, which increases the maintenance cost and affects the continuity of the operation of the hydraulic pump station. Therefore, further improvement is needed. Summary of the Invention

Therefore, further improvement is needed.

[0005] To solve the above problems, the present invention provides a hydraulic pump station fuel tank, which includes a base. A fuel tank is fixedly connected to the top end of the base. A plurality of evenly distributed sedimentation chambers are opened on the inner wall of the bottom end of the fuel tank, and a plurality of evenly distributed refrigeration chambers are opened on the outer wall of the bottom end of the fuel tank. The plurality of sedimentation chambers and the plurality of refrigeration chambers are arranged at intervals. A feed pipe is fixedly connected to the side wall of one end of the fuel tank, and a discharge pipe is fixedly connected to the side wall of the other end of the fuel tank.

The output end of the liquid nitrogen bottle is fixedly connected to a nitrogen delivery pipe, and the output end of the heat engine is fixedly connected to a gas delivery pipe. A transfer pipe is fixedly connected between the nitrogen delivery pipe and the gas delivery pipe. One end of the transfer pipe is fixedly connected to a plurality of dual-purpose nozzles, and the plurality of dual-purpose nozzles are respectively located inside the plurality of refrigeration chambers. A left switching valve is fixedly connected to one end of the transfer pipe close to the nitrogen delivery pipe, and a right switching valve is fixedly connected to one end of the transfer pipe close to the gas delivery pipe.

Two vertical plates are fixedly connected to the top end of the fuel tank, and the two vertical plates are respectively located on both sides of the chute.

[0007] As a further improvement of the present application, a lead screw is rotatably connected between the two vertical plates. The lead screw penetrates through the connecting block and is threadedly connected thereto. A motor is fixedly connected to the side wall of one of the vertical plates, and the output end of the motor is fixedly connected to one end of the lead screw.

[0008] As a further improvement of the present application, a separation pipe matching the sedimentation chamber is fixedly connected to the telescopic end of the electric telescopic rod.

[0025] The following will make a detailed description of the two embodiments of this application with reference to the accompanying drawings.

[0026] The first embodiment:

[0027] Figure 1-2A hydraulic pump station fuel tank is shown, which includes a base 1. The top end of the base 1 is fixedly connected with a fuel tank 2. The inner wall of the bottom end of the fuel tank 2 is provided with a plurality of evenly distributed sedimentation chambers 3. The outer wall of the bottom end of the fuel 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 spaced apart. One side wall of the fuel tank 2 is fixedly connected with an inlet pipe 201, and the other side wall of the fuel tank 2 is fixedly connected with an outlet pipe 202. A chute 203 is opened at the top end of the fuel tank 2. One end of the base 1 is fixedly connected with a liquid nitrogen bottle 5, and the other end of the base 1 is fixedly connected with a hot air engine 6. The output end of the liquid nitrogen bottle 5 is fixedly connected with a nitrogen delivery pipe 501, and the output end of the hot air engine 6 is fixedly connected with an air delivery pipe 601. A transfer pipe 7 is fixedly connected between the nitrogen delivery pipe 501 and the air delivery pipe 601. One end of the transfer pipe 7 is fixedly connected with a plurality of dual-purpose nozzles 8, and the plurality of dual-purpose nozzles 8 are respectively located inside the plurality of refrigeration chambers 4. One end of the transfer pipe 7 close to the nitrogen delivery pipe 501 is fixedly connected with a left switch valve 9, and one end of the transfer pipe 7 close to the air delivery pipe 601 is fixedly connected with a right switch valve 10.

[0028] The hydraulic oil enters the inside 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 settle inside the plurality of sedimentation chambers 3. When there are too many impurities inside the sedimentation chambers 3, the left switch valve 9 is opened, the right switch valve 10 is closed, and liquid nitrogen is released into the refrigeration chambers 4 through the liquid nitrogen bottle 5 and the dual-purpose nozzles 8. At this time, the hydraulic oil inside the sedimentation chambers 3 together with the impurities is frozen. After the impurities are frozen, their density becomes smaller. Then the left switch valve 9 is closed, the right switch valve 10 is opened, and hot air is briefly discharged into the refrigeration chambers 4 through the hot air engine 6 and the dual-purpose nozzles 8 to melt the frozen impurities close to the wall surface of the sedimentation chambers 3. At this time, the frozen impurities are separated from the sedimentation chambers 3, and the frozen impurities are fished out to complete the purification of the hydraulic oil. Through the above settings, compared with removing impurities in the form of a filter screen, the impurities can be removed without stopping the machine, improving the working efficiency of the equipment.

[0029] The second embodiment:

[0030] Figure 1-8 A hydraulic pump station fuel tank is shown. Different from the first embodiment, an electric telescopic rod 12 is slidably connected inside the chute 203. 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 end of the fuel tank 2, and the two vertical plates 13 are respectively located on both sides of the chute 203. A lead screw 14 is rotatably connected between the two vertical plates 13. The lead screw 14 passes through the connecting block 15 and is threadedly connected thereto. The output end of 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 lead screw 14. The telescopic end of the electric telescopic rod 12 is fixedly connected with an isolation pipe 11 matching the sedimentation chamber 3. A sealing ring 1101 is fixedly connected to the top end of the isolation pipe 11, and a bottom valve 801 is fixedly connected to the bottom end of the dual-purpose nozzle 8.

[0031] Since the temperature of the hydraulic oil is relatively high, the freezing efficiency of the impurities inside the sedimentation chamber 3 is low. With the above settings, when cleaning one of the sedimentation chambers 3, the motor 16 can be started to drive the electric telescopic rod 12 to move above the sedimentation chamber 3, and the electric telescopic rod 12 is started to drive the isolation pipe 11 to move into the sedimentation chamber 3. At this time, the isolation pipe 11 can isolate the impurities inside the sedimentation chamber 3 from the hydraulic oil flowing outside it. Then, the left switching valve 9 and the corresponding bottom valve 801 are opened, and the impurities between the sedimentation chamber 3 and the isolation pipe 11 are frozen, improving the freezing efficiency of the impurities and reducing the waste of cold energy.

[0032] Inside the oil tank 2 near the bottom end of the inlet pipe 201, a cooling chamber 19 is provided. The top end of the cooling chamber 19 is fixedly connected with a cold plate 1901. One end of the nitrogen delivery pipe 501 is fixedly connected with a liquid nitrogen branch pipe 20. One end of the liquid nitrogen branch pipe 20 extends into the cooling chamber 19, and the other end of the liquid nitrogen branch pipe 20 is fixedly connected with a sub-valve 2001.

[0033] Since the temperature of the hydraulic oil is relatively high, the frozen impurities will accelerate dissolution during the floating process, resulting in the impurities redissolving and falling into the hydraulic oil. With the above settings, before freezing the impurities, the sub-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 decreases, playing a role in cooling the hydraulic oil. When waiting for the temperature of the hydraulic oil to drop to 0 - 10 degrees Celsius, the impurities are frozen again. At this time, during the floating process of the frozen impurities, the dissolution amount of the impurities can be reduced, improving the removal effect of the impurities.

[0034] An adapter plate 22 is fixedly connected to the inner wall of the oil tank 2 near the inlet pipe 201. A sewage discharge groove 21 is provided on the side wall of the oil tank 2 near the adapter plate 22. One end of the gas delivery pipe 601 is fixedly connected with a hot air branch pipe 17. One end of the hot air branch pipe 17 extends into the oil tank 2, and the other end of the hot air branch pipe 17 is fixedly connected with a gas valve 1701. A flexible pipe 18 is fixedly connected between one end of the hot air branch pipe 17 located inside the oil tank 2 and the top end of the isolation pipe 11. An exhaust pipe 1102 is provided at the top end of the isolation pipe 11.

[0035] After the impurities between the sedimentation chamber 3 and the isolation pipe 11 are frozen, the impurities will also adhere to the surface of the isolation pipe 11. When the electric telescopic rod 12 drives the isolation pipe 11 to rise, it will drive the frozen impurities to rise. Then, the isolation pipe 11 moves above the adapter plate 22, the gas valve 1701 and the hot air machine 6 are opened to blow hot air into the isolation pipe 11. After the temperature of the isolation pipe 11 rises, the frozen impurities adhering to its surface dissolve and fall onto the adapter plate 22. With the above settings, the transfer of the frozen impurities can be completed.

[0036] Combined with the current actual requirements, the above-described implementation manner adopted in this application, the protection scope is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
