Description

Technical Field

[0001] The utility model relates to the technical field of cooling the temperature of an atomizer, in particular to a cooling device for lubricating oil of an atomizer. Background Art

[0002] The gear-variable high-speed rotary atomizers currently used in the market are basically imported from Denmark. The power element of the atomizer requires an extremely high speed. The power element is usually composed of a motor and a gearbox. The output shaft of the motor is connected to the input shaft of the gearbox through a coupling, but the gears and shafts in the gearbox will generate a lot of heat during the rotation process, and there will be a lot of lubricating oil in the gearbox. The lubricating oil not only plays the role of lubrication, but also can take away the heat generated by the high-speed rotation in the gearbox. Therefore, the lubricating oil will heat up very quickly, especially in summer, and the lubricating oil temperature limit that the equipment accessories can withstand is between 90-100℃. In the case of high ambient temperature in summer, generally only a few fans can be added on site to maintain operation, but the heat of the lubricating oil is difficult to dissipate in a short time, and the fundamental problem cannot be solved. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide an atomizer lubricating oil cooling device for solving the problem in the prior art that the lubricating oil in the atomizer is difficult to cool, which affects the use of the equipment.

[0004] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:

[0005] A device for cooling lubricating oil of an atomizer comprises a cooling box body, the cooling box body is provided with a water inlet, a water outlet, an oil inlet and an oil outlet, the inner cavity of the cooling box body comprises a liquid inlet end, a liquid outlet end and a cooling cavity arranged between the liquid inlet end and the liquid outlet end; a plurality of heat sinks are evenly arranged in the cooling cavity, and the cooling cavity is divided into a plurality of water storage cavities and oil storage cavities arranged at intervals; a plurality of through holes are opened on the heat sink plate, and adjacent water storage cavities and adjacent oil storage cavities are connected by sealed pipes penetrating the through holes.

[0006] To implement the above technical solution, the heat sink in the present application divides the cooling chamber into a water storage chamber and an oil storage chamber which are arranged at intervals. The heat sink is used to exchange heat between the high-temperature lubricating oil and the cooling water. The front and rear sides of each oil storage chamber are heat sinks, and the high-temperature lubricating oil can dissipate heat through multiple oil storage chambers, which can effectively reduce the oil temperature and increase the service life of the atomizer. Adjacent water storage chambers and adjacent oil storage chambers are connected by sealed pipes, which can effectively prevent water and oil mixing. The device can be connected using the pipes of the atomizer without generating any pollution or energy consumption.

[0007] In one embodiment of the utility model, the liquid inlet end includes a water inlet chamber connected to the water inlet and an oil inlet chamber connected to the oil inlet; the liquid outlet end includes a water outlet chamber connected to the water outlet and an oil outlet chamber connected to the oil outlet.

[0008] To implement the above technical solution, during operation, cooling water flows from the water inlet into the water inlet chamber, flows through each water storage chamber in sequence, then flows into the water outlet chamber, and is discharged from the water outlet; lubricating oil flows from the oil inlet into the oil inlet chamber, flows through each oil storage chamber in sequence, then flows into the oil outlet chamber, and is discharged from the oil outlet. Since the oil storage chamber and the water storage chamber are arranged at intervals, the lubricating oil can be quickly cooled down. In actual work, the refrigerant can also be replaced with gas as needed.

[0009] In one embodiment of the utility model, each of the water storage chamber and the oil storage chamber includes a liquid inlet and a liquid outlet, and the liquid inlet and the liquid outlet of the same water storage chamber and the same oil storage chamber are staggeredly arranged at upper and lower angles.

[0010] To implement the above technical solution, the advantage of staggered upper and lower angles of the liquid inlet and the liquid outlet is that it can increase the time for the liquid to flow through the cooling chamber and fully contact the heat sink, thereby ensuring the cooling effect of the lubricating oil.

[0011] In one embodiment of the present invention, the heat sink includes two symmetrical heat sinks that are folded at a certain angle, the lower portion of the heat sink is rectangular, and the upper portion of the heat sink is a right triangle.

[0012] By implementing the above technical solution, compared with a heat sink with a planar design, the heat sink of the present invention has the advantage of being able to increase the contact area between the cooling water or lubricating oil and the heat sink, thereby improving the heat dissipation effect.

[0013] In one embodiment of the present invention, the heat sink is composed of a flat plate portion and a plurality of concave-convex structures; the plurality of concave-convex structures are arranged at intervals from each other, and the plurality of concave-convex structures are all located on the same side of the protrusion or depression of the flat plate portion.

[0014] By implementing the above technical solution, the surface area of ​​the heat sink can be increased by setting the concave-convex structure, thereby improving the cooling effect of the lubricating oil.

[0015] In an embodiment of the present invention, a plurality of the concave-convex structures are in the shape of inclined strips or corrugations.

[0016] By implementing the above technical solution, the strip-shaped or corrugated concave-convex structure can increase the rigidity and pressure-bearing capacity of the heat sink and promote the turbulent flow of the liquid, thereby reducing the formation of sediment or dirt.

[0017] In an embodiment of the present invention, a sealing plug is embedded between the pipe and the through hole.

[0018] To implement the above technical solution, the sealing plug may be made of rubber, which can effectively prevent leakage of cooling water or lubricating oil and ensure stable operation of the atomizer.

[0019] As described above, an atomizer lubricating oil cooling device of the utility model has the following beneficial effects: in the present application, the heat sink separates the cooling chamber into a water storage chamber and an oil storage chamber which are arranged at intervals, and the high-temperature lubricating oil and cooling water are heat exchanged through the heat sink. The front and rear sides of each oil storage chamber are heat sinks, and the high-temperature lubricating oil can dissipate heat through multiple oil storage chambers, which can effectively reduce the oil temperature and increase the service life of the atomizer. Adjacent water storage chambers and adjacent oil storage chambers are connected by sealed pipes, which can effectively prevent water and oil mixing, and the device can be connected using the pipes of the atomizer without generating any pollution or energy consumption.

[0029] In the present application, the heat sink 6 divides the cooling chamber into a water storage chamber and an oil storage chamber that are spaced apart. The heat sink 6 is used to exchange heat between the high-temperature lubricating oil and the cooling water. The front and rear sides of each oil storage chamber are heat sinks 6, and the high-temperature lubricating oil can dissipate heat through multiple oil storage chambers, which can effectively reduce the oil temperature and increase the service life of the atomizer. Adjacent water storage chambers and adjacent oil storage chambers are connected by sealed pipes 8, which can effectively prevent water and oil from mixing. The device can be connected using the pipe 8 of the atomizer without generating any pollution or energy consumption.

[0030] The liquid inlet end includes a water inlet chamber 9 connected to the water inlet 2 and an oil inlet chamber 10 connected to the oil inlet 4; the liquid outlet end includes a water outlet chamber 11 connected to the water outlet 3 and an oil outlet chamber 12 connected to the oil outlet 5.

Since the oil storage chamber and the water storage chamber are arranged at intervals, the lubricating oil can be cooled down quickly. In actual operation, the refrigerant can also be replaced with gas as needed.

[0031] Each of the water storage chamber and the oil storage chamber includes a liquid inlet and a liquid outlet, and the liquid inlet and the liquid outlet of the same water storage chamber and the same oil storage chamber are arranged at upper and lower angles. The advantage of the staggered arrangement of the liquid inlet and the liquid outlet at upper and lower angles is that it can increase the time for the liquid to flow through the cooling chamber and fully contact with the heat sink 6, thereby ensuring the cooling effect of the lubricating oil.
