[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example: Figures 1-6As shown, the utility model provides a technical solution for a cooling and cooling device for a thin oil station, characterized in that: the cooling and cooling device for the thin oil station comprises a mounting plate 1, a thin oil station 2 is mounted on the mounting plate 1, a partition 3 is mounted in the thin oil station 2, the partition 3 divides the thin oil station 2 into an oil pump chamber 4 and a thin oil working chamber 5, a first through hole 7 and a second through hole 8 are symmetrically opened in the thin oil working chamber 5, an oil pump 6 is mounted in the oil pump chamber 4, the oil pump 6 is connected to the first through hole 7 through an oil pump inlet pipe 9, the oil pump 6 is connected to the second through hole 8 through an oil pump outlet pipe 10, and a mounting plate is mounted above the oil pump chamber 4. Frame 11, four connecting frames 12 are symmetrically installed in the installation frame 11, and the four connecting frames 12 are connected by a support plate 13. A drive motor 15 and a water tank 16 are installed on the support plate 13. The drive motor 15 is provided with an annular water baffle 17, and a water flow trough 14 is provided on the support plate 13. The output shaft of the drive motor 15 passes through the support plate 13, and a rotating column 18 is installed on the output shaft of the drive motor 15. The rotating column 18 is located below the support plate 13, and a water storage tank 20 is concentrically installed on the rotating column 18. The water storage tank 20 and the support plate 13 are sealed by an L-shaped sealing ring. 19 is connected, a fan 21 is concentrically installed on the rotating column 18, a plurality of water holes 22 are opened on the wall of the water storage tank 20, a plurality of drain pipes 23 are installed on the water outlet holes 22, and a plurality of heat dissipation holes 24 are opened on the wall of the oil pump chamber 4. When the thin oil station 2 is working, the oil pump 6 pumps the lubricating oil from the oil pump inlet pipe 9 to the oil pump outlet pipe 10. At this time, the drive motor 15 is started, and the fan 21 is driven to rotate through the rotating column 18 to cool the working oil pump 6 with air, and the heat generated by the oil pump 6 is blown out from the heat dissipation holes 24 by wind energy. At the same time, the water in the water tank 16 passes through the water trough 14 It flows to the water storage tank 20, flows to the oil pump 6 along the drain pipe 23 through the water outlet 22, and takes away the heat generated by the oil pump 6 through the water. When the rotating column 18 rotates, it will also drive the drain pipe 23 to rotate through the water storage tank 20, so that the water is evenly sprinkled to the oil pump 6, making the heat dissipation of the oil pump 6 more uniform. The wind energy generated by the rotation of the fan 21 can accelerate the evaporation of water, and the evaporation of water absorbs heat and can take away more heat. By using water cooling and air cooling at the same time and combining them, the cooling of the pump 6 is effectively improved, the temperature of the diluent station 2 is reduced, and the continuous and efficient operation of the diluent station 2 is guaranteed.

[0031] The drain pipe 23 is L-shaped and is installed at an angle on the water outlet 22. The drain pipe 23 is located between every two blades of the fan 21. The inclined installation prevents water from not being able to flow out normally due to the centrifugal force generated by the rotation. The drain pipe 23 is installed between the blades to prevent the blades from blocking it, allowing water to flow to the pump 6.

[0032] The L-shaped sealing ring 19 is fixedly mounted on the support plate 13 , and is rotatably mounted on the water storage tank 20 .

[0033] like Figures 1-4 and Figure 7 As shown, a pre-cooling assembly 25 is provided on the mounting plate 1 , and the pre-cooling assembly 25 is connected to the thin oil station 2 via a first through hole 7 .

[0034] The pre-cooling assembly 25 includes a liquid storage tank 2501, a support rod 2502, a heat exchange inner tube 2503, a heat exchange outer tube 2504, an outer tube connecting pipe 2505, a liquid inlet pipe 2506, a liquid return pipe 2507, an oil inlet pipe 2508, an oil outlet pipe 2509, a coolant pump 2510, a fixing ring 2511, a connecting rod 2512, a conical diverter plate 2513 and a guide hole 2514;

[0035] A liquid storage tank 2501 is installed on the mounting plate 1, and a support rod 2502 is installed on the wall of the thin oil station 2 close to the liquid storage tank 2501. A heat exchange inner tube 2503 is installed on the support rod 2502. A plurality of heat exchange outer tubes 2504 are arranged on the outer sleeve of the heat exchange inner tube 2503. The plurality of heat exchange outer tubes 2504 are connected in pairs through outer tube connecting tubes 2505. A liquid inlet pipe 2506 is installed on the lower end of the heat exchange outer tube 2504, and a return pipe 2506 is installed on the upper end of the heat exchange outer tube 2504. Liquid pipe 2507, the liquid inlet pipe 2506 and the liquid return pipe 2507 are extended into the liquid storage tank 2501, the liquid storage tank 2501 is installed with a coolant pump 2510, the coolant pump 2510 pump outlet is connected to the liquid inlet pipe 2506, the upper port of the heat exchange inner tube 2503 is installed with an oil inlet pipe 2508, the upper port of the heat exchange inner tube 2503 is installed with an oil outlet pipe 2509, the oil outlet pipe 2509 is connected to the first through hole 7, and two fixing rings 2503 are installed in parallel in the heat exchange inner tube 2503. 11. The two fixing rings 2511 are connected by a connecting rod 2512. A conical manifold 2513 is concentrically mounted on the two fixing rings 2511. The conical manifold 2513 is provided with a plurality of guide holes 2514. When the thin oil station 2 is working, lubricating oil is pumped in from the outside. When the lubricating oil flows from the oil inlet pipe 2508 into the heat exchange inner tube 2503 and flows from the oil outlet pipe 2509 to the pump 6, the coolant pump 2510 is started to pump the coolant from the liquid storage tank 2501 and out from the liquid inlet pipe 2506. It enters the heat exchange outer tube 2504, exchanges heat with the lubricating oil in the heat exchange inner tube 2503, and finally flows back to the liquid storage tank 2501 from the return liquid pipe 2507. When the lubricating oil flows in the heat exchange inner tube 2503 and contacts the conical diverter plate 2513, the lubricating liquid will be diverted. Due to the existence of the guide hole 2514, the lubricating oil near the middle of the flow stream will flow through first without blocking the flow of the lubricating oil, ensuring that the lubricating oil in the heat exchange inner tube 2503 is evenly and fully exchanged with heat, effectively improving the heat exchange effect between the lubricating oil and the coolant.

[0036] The top end of the conical diverter plate 2513 faces the incoming flow direction, and the two conical diverter plates 2513 are installed so that the guide holes 2514 are staggered to ensure that both conical diverter plates 2513 can divert the lubricating oil.

[0037] The pre-cooling assembly 25 further includes a baffle 2515, a liquid inlet chamber 2516, a cooling chamber 2517, a liquid storage chamber 2518, an electric hinge 2519 and a refrigeration plate 2521;

[0038] Four electric hinges 2519 are installed in the liquid storage tank 2501. Each of the four electric hinges 2519 is installed with a baffle 2515. Two baffles 2515 form a group. The two groups of baffles 2515 divide the liquid storage tank 2501 into a liquid inlet chamber 2516, a cooling chamber 2517, and a liquid storage chamber 2518 from top to bottom. A refrigeration plate 2521 is installed in the cooling chamber 2517.

[0039] The pre-cooling assembly 25 further includes a liquid level sensor 2520 . The liquid level sensor 2520 is installed in the liquid inlet chamber 2516 , and the liquid level sensor 2520 is electrically connected to the electric hinge 2519 .

[0040] The coolant after heat exchange flows back into the liquid inlet chamber 2516 from the return liquid pipe 2507. When the liquid level reaches a certain height, the liquid level sensor 2520 controls the electric hinge 2519 on the lower side, driving a set of baffles 2515 on the lower side to open regularly, so that the cooled coolant flows to the liquid storage chamber 2518. At the same time, the electric hinge 2519 on the upper side is controlled. After the set of baffles 2515 on the lower side are closed, the set of baffles 2515 on the upper side are driven to open regularly, so that the coolant after heat exchange enters the cooling chamber 2517 for cooling, ensuring that low-temperature coolant is continuously provided to the heat exchange outer tube 2504 for heat exchange with the lubricating oil, effectively improving the heat exchange effect and reducing the temperature of the lubricating oil when it flows into the thin oil station 2.

[0041] The working principle of this utility model:

[0042] 23, and the oil pump 6 is cooled by the fan 21.

[0043] When the thin oil station 2 is working, lubricating oil will be pumped in from the outside. When the lubricating oil flows into the heat exchange inner tube 2503 from the oil inlet pipe 2508 and flows to the pump 6 from the oil outlet pipe 2509, the coolant pump 2510 is started to pump the coolant out of the liquid storage tank 2501 and enter the heat exchange outer tube 2504 from the liquid inlet pipe 2506 to exchange heat with the lubricating oil in the heat exchange inner tube 2503, and finally flow back to the liquid storage tank 2501 from the return pipe 2507. When the lubricating oil flows in the heat exchange inner tube 2503 and contacts the conical diverter plate 2513, the lubricating oil will be diverted. The existence of the guide hole 2514 allows the lubricating oil near the middle of the flow stream to flow through first without blocking the flow of the lubricating oil, thereby ensuring that the lubricating oil in the heat exchange inner tube 2503 is evenly and fully heat-exchanged, effectively improving the heat exchange effect between the lubricating oil and the coolant.

[0044] The coolant after heat exchange flows back into the liquid inlet chamber 2516 from the return liquid pipe 2507. When the liquid level reaches a certain height, the liquid level sensor 2520 controls the electric hinge 2519 on the lower side, driving a set of baffles 2515 on the lower side to open regularly, so that the cooled coolant flows to the liquid storage chamber 2518. At the same time, the electric hinge 2519 on the upper side is controlled. After the set of baffles 2515 on the lower side are closed, the set of baffles 2515 on the upper side are driven to open regularly, so that the coolant after heat exchange enters the cooling chamber 2517 for cooling, ensuring that low-temperature coolant is continuously provided to the heat exchange outer tube 2504 for heat exchange with the lubricating oil, effectively improving the heat exchange effect and reducing the temperature of the lubricating oil when it flows into the thin oil station 2.
