[0022] The working principle of the present invention is: when in use, after the thin oil is lubricated by the CNC machine tool, the thin oil is collected on the left side of the collection tank 1, falls into the heat dissipation box 4 after passing through the filter screen, and then enters the storage box 5 through the three-way pipe 16. Finally, the thin oil is pumped into the liquid outlet through the telescopic pipe 6 and the coil 8 by the water pump. The liquid outlet is provided with a temperature sensor for recycling.

[0023] After being used for a period of time, impurities accumulate on the left side of the collecting tank 1, and the transmission rod 18 is driven to rotate by the motor 11. The transmission rod 18 drives the storage plate 15 to rotate through the bevel gear set 17, thereby driving the cleaning mesh plate 14 to move. The cleaning mesh plate 14 is restricted by the guide groove 13 and pushes the impurities accumulated on the partition 2 to the upper right and falls into the collection frame 3 for collection.

[0024] After using for a period of time, the temperature of the thin oil rises, and the heat is dissipated through the fins on the outside of the heat sink 4, and finally discharged through the pump.

When the temperature continues to rise, the heat dissipation fan 9 blows cold air, the heat sink 10 uses the cold air to cool the fins, and the stirring blades 12 stir to improve uniformity.
