Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic pump stations, in particular to an energy-saving hydraulic pump station for a briquetting machine. Background Art

[0002] A hydraulic station is a hydraulic device that supplies oil according to the required flow direction, pressure, and flow rate. The existing traditional hydraulic station consists of an oil tank, a motor, a vane pump, a radiator, a solenoid valve, and an energy storage tank. Its working principle is that when the motor is powered on and rotates, it drives the vane pump to output hydraulic pressure, that is, the vane pump pumps out the liquid in the oil tank. When the pressure reaches the set value, the pressure relief valve opens, and the excess liquid flows back to the oil tank.

[0003] For example, the patent with the publication number CN221591422U discloses an energy-saving hydraulic station, including a base. The lower end surface of the base is fixedly provided with an installation box. The bottom inside the installation box is fixedly provided with a protection box and a water tank. The water tank is located on the right side of the protection box. A cooling component is arranged inside the protection box; the cooling component includes a water pump, a cooling mechanism, and a temperature sensor. By setting the water pump, the cooling mechanism, and the temperature sensor, the water pump and the cooling mechanism can gradually cool the water inside the water tank, and the temperature sensor can monitor the water temperature, so as to ensure that the water temperature is within a suitable range, and thus can play a role in cooling the hydraulic oil; the setting of the servo motor, the hydraulic pump, and the solenoid valve. The servo motor can drive the hydraulic pump to operate, and the hydraulic pump can thus play a role in controlling the hydraulic equipment, and the solenoid valve can play a role in controlling the flow rate of the hydraulic oil.

[0004] However, in the prior art, components such as pumps, valves, and cylinders in the hydraulic system will wear during long-term operation. The metal particles or fragments generated by these wears will enter the hydraulic oil and become part of the impurities, and these impurities will affect the normal operation of the equipment, resulting in a certain degree of limitation in the practicality of the device. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that components such as pumps, valves, and cylinders in the hydraulic system will wear during long-term operation in the prior art. The metal particles or fragments generated by these wears will enter the hydraulic oil and become part of the impurities, and these impurities will affect the normal operation of the equipment.

[0006] To achieve the above object, the utility model adopts the following technical scheme: An energy-saving hydraulic pump station for a briquetting machine, comprising a box body, on one side of the upper surface of the box body, there is an oil tank, on the surface of the oil tank, there is a filtering mechanism slidably connected, on the outer surface of the filtering mechanism, there is a handle fixedly connected, on both sides of the filtering mechanism, there are positioning holes symmetrically opened, inside the positioning holes, there are positioning rods inserted, one end of the positioning rod is fixedly connected with a push-pull block, and the inner side of the push-pull block is fixedly connected with the outer side wall of the oil tank through a return spring.

[0007] As a preferred embodiment, on the other side of the upper surface of the box body, there is a hydraulic pump, and outside the hydraulic pump, there is a servo motor.

[0008] As a preferred embodiment, the input end of the hydraulic pump is fixedly connected with the oil tank through a guide pipe, and on the surface of the guide pipe, there is a solenoid valve.

[0009] As a preferred embodiment, on the surface of the box body, there are box doors symmetrically hinged, on one side of the inner cavity of the box body, there is a cooling box fixedly connected, and on the lower surface of the cooling box, there is a heating plate fixedly connected.

[0010] As a preferred embodiment, on the other side of the inner cavity of the box body, there is a cooling mechanism, and on the outer side wall of the cooling mechanism, there is a circulation pump.

[0011] As a preferred embodiment, the input end of the circulation pump is fixedly connected with the cooling box through a first connecting pipe, and the output end of the cooling mechanism is fixedly connected with the cooling box through a second connecting pipe.

[0012] As a preferred embodiment, the output end of the hydraulic pump is fixedly connected with an oil outlet pipe, and the oil outlet pipe is arranged inside the cooling box.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are as follows:

[0014] By setting a detachable filtering component, the impurities in the hydraulic oil are filtered. When the hydraulic oil flows back to the oil tank, it will pass through the filtering mechanism to filter the worn impurities in the hydraulic oil, preventing the impurities from re-entering the hydraulic oil and affecting the normal use of the equipment. The long-term use of the hydraulic oil will also cause the filtering mechanism to become blocked. When the filtering mechanism is blocked, pull the push-pull block outward to compress the return spring, so that the positioning rod is removed from the positioning hole, thereby quickly disassembling and cleaning the filtering mechanism, improving the quality of the hydraulic oil, and ensuring the stable operation of the equipment.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5, the present utility model provides a technical solution: an energy-saving hydraulic pump station for a briquetting machine, including a box body 1. On one side of the upper surface of the box body 1, there is an oil tank 14. A filtering mechanism 15 is slidably connected to the surface of the oil tank 14. A handle 16 is fixedly connected to the outer surface of the filtering mechanism 15. Positioning holes 17 are symmetrically opened on both sides of the filtering mechanism 15. A positioning rod 18 is inserted into the positioning holes 17. One end of the positioning rod 18 is fixedly connected to a push-pull block 20. The inner side of the push-pull block 20 is fixedly connected to the outer side wall of the oil tank 14 through a return spring 19. When the hydraulic oil flows back into the oil tank 14, it will pass through the filtering mechanism 15 to filter out the worn impurities in the hydraulic oil, preventing the impurities from re-entering the hydraulic oil and affecting the normal use of the equipment. Prolonged use of the hydraulic oil will also cause the filtering mechanism 15 to become blocked. When the filtering mechanism 15 becomes blocked, pull the push-pull block 20 outward to compress the return spring 19, so that the positioning rod 18 is removed from the positioning hole 17, thereby quickly disassembling and cleaning the filtering mechanism 15, improving the quality of the hydraulic oil, and ensuring the stable operation of the equipment.

[0024] As Figures 1-5 shown, on the other side of the upper surface of the box body 1, there is a hydraulic pump 9. A servo motor 11 is arranged outside the hydraulic pump 9. The input end of the hydraulic pump 9 is fixedly connected to the oil tank 14 through a guide pipe 12. A solenoid valve 13 is arranged on the surface of the guide pipe 12. Box doors 2 are symmetrically hinged on the surface of the box body 1. On one side of the inner cavity of the box body 1, there is a cooling box 7 fixedly connected. A heating plate 8 is fixedly connected to the lower surface of the cooling box 7. The heating plate 8 can heat the hydraulic oil in a low-temperature state, preventing the hydraulic oil from condensing, ensuring the stable oil supply of the equipment, and improving the practicability of the device.

[0025] As Figures 1-5 shown, on the other side of the inner cavity of the box body 1, there is a cooling mechanism 3. A circulation pump 4 is arranged on the outer side wall of the cooling mechanism 3. The input end of the circulation pump 4 is fixedly connected to the cooling box 7 through a first connecting pipe 5. The output end of the cooling mechanism 3 is fixedly connected to the cooling box 7 through a second connecting pipe 6. The output end of the hydraulic pump 9 is fixedly connected to an oil outlet pipe 10, and the oil outlet pipe 10 is arranged in the inner cavity of the cooling box 7. The input end of the circulation pump 4 transports the coolant in the cooling box 7 to the cooling mechanism 3 through the first connecting pipe 5 for cooling. After cooling, the coolant is re-transported to the cooling box 7 through the second connecting pipe 6 to cool down the hydraulic oil in the oil outlet pipe 10, further ensuring the normal operation of the equipment.

[0026] Working principle: During use, the servo motor 11 starts to drive the hydraulic pump 9 to operate. The hydraulic pump 9 transports the hydraulic oil in the fuel tank 14 to the outlet pipe 10 through the guide pipe 12, and controls the flow rate of the hydraulic oil through the solenoid valve 13. At this time, the input end of the circulation pump 4 transports the coolant in the cooling tank 7 to the cooling mechanism 3 for cooling through the first connecting pipe 5. After cooling, the coolant is re-transported to the cooling tank 7 through the second connecting pipe 6 to cool the hydraulic oil in the outlet pipe 10. At this time, the hydraulic oil after cooling is re-entered into the fuel tank 14 after use, so as to recycle the hydraulic oil in turn. Components such as pumps, valves, and cylinders in the hydraulic system will wear during long-term operation. Metal particles or fragments generated by these wear will enter the hydraulic oil and become part of the impurities. These impurities will affect the normal operation of the equipment. Therefore, a detachable filter assembly is added. When the hydraulic oil flows back to the fuel tank 14, the filtering mechanism 15 will filter out the worn impurities in the hydraulic oil to prevent the impurities from re-entering the hydraulic oil and affecting the normal use of the equipment. The long-term use of the hydraulic oil will also cause the filtering mechanism 15 to become blocked. When the filtering mechanism 15 becomes blocked, pull the push-pull block 20 outward and compress the return spring 19 to move the positioning rod 18 out of the positioning hole 17, so as to quickly disassemble and clean the filtering mechanism 15, improve the quality of the hydraulic oil, and ensure the stable operation of the equipment. The heating plate 8 can heat the hydraulic oil in a low-temperature state to prevent the hydraulic oil from condensing, further ensuring the normal operation of the equipment.

[0027] The above are only the preferred embodiments of the present invention, and do not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
