Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figures 1-4, the present utility model provides a device for recycling cutting fluid, which includes a tray 1. A through pipe 3 is fixedly connected to the lower end of the tray 1. A filter cylinder 4 is screwed on the outer wall of the lower end of the through pipe 3. A filter screen 9 is rotatably assembled on the inner wall of the filter cylinder 4 through a bracket. A rotating structure 7 is assembled at the upper end of the filter screen 9. The rotating structure 7 penetrates the filter cylinder 4. Two sides of the filter cylinder 4 are symmetrically connected with impurity discharge pipes 5. A top cover 6 is screwed on the outer side end of the impurity discharge pipe 5.

[0017] Through the function of the tray 1, the used cutting fluid is received. The used cutting fluid is sent to the filter cylinder 4 through the through pipe 3 and filtered through the filter screen 9 to ensure the treatment effect of the cutting fluid. Through the function of the rotating structure 7 and the setting of the impurity discharge pipe 5, the top cover 6 can be removed regularly, the impurity discharge pipe 5 can be opened, and the impurities can be discharged through the impurity discharge pipe 5. At this time, the rotating structure 7 can be used to rotate the filter screen 9. The filter screen 9 is a conical structure, and the impurities will accumulate on the lower side. As the filter screen 9 rotates to the position of the impurity discharge pipe 5, existing adsorption devices (such as vacuum cleaners) can be used to suck out the impurities, ensuring the filtering effect of the filter screen 9, and at the same time, the maintenance is simple, convenient and fast.

[0018] The rotating structure 7 includes a waterproof housing 71. The waterproof housing 71 is fixedly assembled on the inner wall of the filter cylinder 4. A turntable 72 is rotatably assembled on the inner wall of the waterproof housing 71. The turntable 72 penetrates the filter cylinder 4 and the waterproof housing 71. A transmission belt 73 is fixedly assembled at the lower end of the turntable 72. The lower end of the transmission belt 73 is rotatably assembled on the inner wall of the waterproof housing 71. A sealing plug 74 is penetrated and assembled on the inner wall of the waterproof housing 71. The outer side end of the transmission belt 73 penetrates the sealing plug 74 and is connected to the filter screen 9.

[0019] When the rotating structure 7 needs to be used, first rotate the turntable 72 to drive one side of the transmission belt 73 to rotate. The transmission belt 73 drives the roller on the other side to rotate through the connected belt and drives the filter screen 9 to rotate. At this time, through the functions of the bracket and the tight fit between the filter screen 9 and the inner wall of the filter cylinder 4, the stability of the rotation of the filter screen 9 can be ensured, and through the functions of the waterproof housing 71 and the sealing plug 74, the liquid is prevented from entering the position of the turntable 72.

The liquid inlet pipe 82 is connected to a cooling water pump.

[0022] Through the action of the cooling structure 8, the heat in the cutting fluid is discharged in time during the working process, keeping the cutting fluid within an appropriate temperature range and avoiding overheating and deterioration. At this time, the cooling water pump pumps the cooling water into the inner cavity of the annular cylinder 81 through the liquid inlet pipe 82. The annular cylinder 81 is sleeved on the outer wall of the through pipe 3 to take away the heat in the cutting fluid and is drawn out through the liquid discharge pipe 83 and discharged into the water tank.
