[0022] The cooling device of the hydraulic station of the ladle cleaning machine of the utility model further increases the contact area between the cooling pipe 6 and the hydraulic oil by spirally winding the cooling pipe 6 on the outer surface of the oil tank 3, so that the two can be in full contact. After the fan 504 performs preliminary cooling on the refluxed water, it is then cooled for the second time by the spray pipe 503, which can effectively increase the cooling speed of the device, ensure the cooling effect of the device on the hydraulic oil, and thus ensure the stable operation of the ladle cleaning machine.

[0023] Preferably, a style plate 505 fixed below the spray pipe 503 is provided inside the cooling water tank 501 in the embodiment of the utility model.

[0024] The style plate 505 can help to evenly distribute the sprayed water mist so that it can be in better contact with the air, thereby improving the heat exchange efficiency and further improving the cooling effect of the device.

[0025] Preferably, in the embodiment of the utility model, a return water circulation pump 601 is provided at one end of the cooling pipe 6 connected to the spray pipe 503 , and a water inlet circulation pump 602 is provided at one end of the cooling pipe 6 connected to the water storage tank 502 .

[0026] The separate provision of the return water circulation pump 601 and the inlet water circulation pump 602 can effectively promote the circulation of cooling water, improve the circulation efficiency, and can also well control the flow direction and rate of cooling water, which helps to improve the stability and reliability of the cooling device.

[0027] Preferably, the cooling water tank 501 in the embodiment of the utility model is provided with a water inlet 506 on the side away from the hydraulic station 1, and the water storage tank 502 is provided with a water outlet 507 on the side away from the hydraulic station 1.

[0028] The water inlet 506 and the water outlet 507 are respectively provided to effectively prevent the accumulation of hot spots in the system. The water inlet 506 can timely introduce new cooling water to prevent excessive heat accumulation in the system, while the water outlet 507 can timely discharge the heated cooling water that will not participate in the subsequent circulation, thereby avoiding the formation of local high-temperature areas in the system and helping to maintain the stable operation of the system.

[0029] Preferably, in the embodiment of the utility model, a water inlet valve 508 is provided on the water inlet 506 , and a water outlet valve 509 is provided on the water outlet 507 .

[0030] Corresponding water inlet valve 508 and water outlet valve 509 are respectively provided on the water inlet 506 and the water outlet 507, which can adjust the water inlet and outlet flow as needed to replenish the water evaporated after heat exchange, thereby controlling the total amount of circulating cooling water; when the device needs to be maintained, repaired or replaced, the water outlet valve 509 can be opened to empty the interior.

[0031] Preferably, a plurality of spray holes 510 are provided on the spray pipe 503 in the embodiment of the utility model.

[0032] The embodiment of the utility model does not limit the specific specifications of the spray holes 510. Specifically, a plurality of spray holes 510 are equidistantly arranged along the axial direction of the spray pipe 503. The spray holes 510 have the same specifications, a diameter range of 1mm-2mm, and a center distance range of 5mm-15mm between any two adjacent spray holes 510. By reducing the diameter of the spray holes 510 and reducing the center distance between any two adjacent spray holes 510, the heat dissipation efficiency and uniformity of the sprayed spray liquid can be greatly improved.

[0033] Preferably, a dustproof protective shell 511 is provided on the outside of the fan 504 in the embodiment of the utility model.

[0034] The dustproof protective shell 511 can prevent dust, particles and other debris from entering the interior of the fan 504 , which helps to reduce wear and damage to internal components and extend the service life of the fan 504 .

[0035] Preferably, the fan 504 in the embodiment of the present invention is an axial flow fan.

[0036] The airflow of an axial flow fan during operation mainly flows along the axial direction, so the wind resistance is very small, which can greatly improve the working efficiency. Compared with centrifugal fans, axial flow fans often have smaller pressure losses, so the required driving power is also smaller, which can reduce the cost of use.

[0037] Preferably, the outer shell material of the cooling tower 5 in the embodiment of the utility model is stainless steel.

[0038] Stainless steel has excellent corrosion resistance and can resist corrosion and oxidation in a humid environment, extending the service life of the cooling tower 5 and reducing maintenance costs.

[0039] Preferably, the water inlet 506 in the embodiment of the utility model is arranged near the top of the cooling water tank 501 , and the water outlet 507 is arranged near the bottom of the water storage tank 502 .

[0040] The water inlet 506 is set at a position closer to the top of the water tank, which can utilize the gravity of the water to make the water flow into the cooling water tank 501 with greater pressure, thereby increasing the cooling efficiency and reducing the amount of air or bubbles brought in; the water outlet 507 is set at a position closer to the bottom of the water storage tank 502, which helps to effectively utilize the gravity of the water, ensure that the water flow can be discharged smoothly, and discharge gas or bubbles that may exist at the bottom.

[0041] The embodiment of the utility model does not limit the specific positions of the water inlet 506 and the water outlet 507. Specifically, the water inlet 506 is set at 10cm-20cm from the top of the cooling water tank 501, and the water outlet 507 is set at 10cm-20cm from the bottom of the water storage tank 502.

[0042] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0043] The working process of the cooling device of the hydraulic station of the bag lifting and cleaning machine in the embodiment of the utility model is as follows:

[0044] During use, water is first injected into the cooling water tank 501 through the water inlet pipe, and then the water flows through the cooling water tank 501 into the water storage tank 502; when the water volume in the water storage tank 502 reaches a preset value, the water inlet circulation pump is started to transport water to the cooling pipe 6, and the cooling pipe 6 is spirally wound on the outer surface of the oil tank 3, which can fully cool the oil tank 3; then, after the water flow is heated, it flows out through the other end of the cooling pipe 6, and enters the spray pipe 503 of the cooling water tank 501 through the return water circulation pump 6. At the same time, the axial flow fan blows air downward to accelerate cooling. After that, the water obtained in the spray pipe 503 that has undergone preliminary cooling flows downward through the style plate 505 to achieve further cooling, and finally flows back into the water storage tank 502 to complete the cycle.

[0045] It can be seen that the cooling device of the hydraulic station of the ladle cleaning machine of the utility model further increases the contact area between the cooling pipe 6 and the hydraulic oil by spirally winding the cooling pipe 6 on the outer surface of the oil tank 3, so that the two can be fully in contact. After the fan 504 performs preliminary cooling on the refluxed water, it is then cooled for the second time by the spray pipe 503, which can effectively increase the cooling speed of the device, ensure the cooling effect of the device on the hydraulic oil, and thus ensure the stable operation of the ladle cleaning machine.
