This method has single heat dissipation conditions and slow heat exchange rate, which cannot meet the heat dissipation needs of high-power tower mills. In addition, the current lubrication system lacks devices to remove metal impurities and cannot separate impurities from the lubricating oil. In the long run, impurities in the lubricating oil will also wear out the equipment. Utility Model Content

[0031] The box cover assembly 1 comprises a cover body, on which a liquid inlet pipe 101 , a pump body 102 , a baffle cover 103 and a liquid discharge pipe 104 are provided.

[0032] The inlet of the liquid inlet pipe 101 is connected to the oil outlet of the tower mill lubrication system, and the outlet of the liquid inlet pipe 101 is provided with a baffle 103 for blocking the impact of the liquid flow; the baffle 103 prevents the liquid flow from directly impacting the oil inlet tank 203 and stirring the impurities at the bottom of the oil inlet tank 203, thereby preventing the stirred impurities from flowing into the oil outlet tank 204.

[0033] The outlet of the drain pipe 104 is connected to the inlet of the pump body 102 , and the pump body 102 is connected to the oil inlet of the tower mill lubrication system; the inlet of the drain pipe 104 is close to the bottom of the cooling box 2 .

[0035] A plurality of heat sinks 205 for heat dissipation are arranged on the outer facade of the box body 201; a heat dissipation protrusion 206 for enhancing heat dissipation is arranged at the bottom of the box body 201.

[0039] A plurality of nozzles 304 are provided on the cooling pipe 303 , and the cooling pipe 303 is connected to an external water source pipeline; the heat dissipation protrusion 206 is entirely surrounded in the heat dissipation box 3 .

[0040] The nozzle 304 sprays water mist, the ventilation holes 302 enhance air flow, the water mist exchanges heat with the heat dissipation protrusions 206, and the heat of the box body 201 is taken away with the evaporation of the water mist and the air flow, thereby achieving the function of enhancing heat dissipation.

[0041] In this embodiment, the heat dissipation protrusion 206 is a corrugated protrusion, and the heat dissipation protrusion 206 increases the heat dissipation area at the bottom of the box body 201 and enhances the heat dissipation effect of the box body 201.

The magnetic separation disc 4 is movably placed in the oil inlet tank 203, and when it needs to be cleaned, the magnetic separation disc 4 can be taken out as a whole by hand with the help of the handle 404.

[0043] The specific implementation is as follows:

[0044] The lubricating oil circulates into the cooling box 2 through the box cover assembly 1, and the lubricating oil is precipitated in the oil inlet tank 203. The magnetic separation disk 4 absorbs metal impurities in the lubricating oil. The clean oil on the upper layer of the oil inlet tank 203 passes over the partition 202 and enters the oil outlet tank 204. The cooling box 2 and the heat sink 3 jointly dissipate the heat of the lubricating oil, and the pump body 102 pumps the cooled and impurity-free lubricating oil back into the lubrication system.
