[0007] Furthermore, an oil tank, a rotating drum, and a rotating shaft are installed in the separation cylinder. The rotating shaft is coaxially installed with the separation cylinder, and the lower end of the rotating shaft is connected to the power output end of the separation motor installed outside the separation cylinder. Horizontal connecting rods are evenly installed on the rotating shaft, and the rotating drum is installed on the connecting rod. The oil tank is coaxially suspended in the separation cylinder, and the liquid outlet at the top of the oil tank is installed on the upper support platform of the frame and can be connected to an external oil pump.

[0014] In order to more clearly illustrate the technical solution implemented by the present invention, the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0015] See Figure 1-3 , an oil-liquid separation device for a CNC grinding machine tool, comprising a separation cylinder 1, a filter device 2, a frame 3, and a separation motor 4; the separation cylinder 1 is mounted on a support platform at the lower part of the frame 3, the filter device 2 is mounted on the support platform of the frame 3 above the oil tank 11, the outlet of the filter device 2 is opposite to the drum 12, the separation cylinder 1 is used to quickly centrifuge the waste oil and the cutting fluid, and the filter device 2 separates the waste chips from the oil-liquid mixture to prevent the waste chips from affecting the oil-liquid separation efficiency.

[0016] See Figure 1-3 An oil tank 11, a drum 12, and a rotating shaft 13 are installed in the separation cylinder 1. The rotating shaft 13 is coaxially installed with the separation cylinder 1. The lower end of the rotating shaft 13 is connected to the power output end of the separation motor 4 installed outside the separation cylinder 1. Horizontal connecting rods are evenly installed on the rotating shaft 13, and the drum 12 is installed on the connecting rod. The oil tank 11 is coaxially suspended in the separation cylinder 1. The top outlet of the oil tank 11 is installed on the upper support platform of the frame 3 and can be connected to an external oil pump. During the centrifugal separation stage, the waste oil as the light component flows into the middle oil tank 11, and the cutting fluid as the heavy component passes through the drum 12, enters the outer separation cylinder 1, and is discharged from the outlet.

[0017] See Figure 1-3The filtering device 2 includes a filter box 21, an electric heating strip 22, a magnetic stirring rod 23, a stirring shaft 24, and a stirring motor 25. The bottom surface of the filter box 21 is a filter mesh disk, and the electric heating strip 22 is installed on the inner side of the filter box 21. The power input end of the upper end of the stirring shaft 24 is connected to the power output end of the stirring motor 25 installed on the top of the frame 3. The magnetic stirring rod 23 is evenly installed on the stirring shaft 24. The magnetic stirring rod 23 absorbs the waste to avoid clogging the filter mesh disk at the bottom of the box. The electric heating strip 22 melts the condensed oil and flows it into the separation cylinder 1 below, avoiding the oil pollution affecting the recovery efficiency when the waste is recovered.

[0018] According to the above embodiment, the working process of the utility model is as follows:

[0019] The oil-liquid mixture collected by the grinding machine is poured into the filter box 21. The electric heating strip 22 melts the solidified oil stains, and the stirring motor 25 is started. The magnetic stirring rod 23 stirs and absorbs the waste chips in the filter box 21 to separate the waste chips from the liquid mixture. After the liquid mixture flows into the separation cylinder 1 below, the separation motor 4 is started, and the shaft 13 drives the drum 12 to rotate to centrifugally separate the liquid mixture. The waste oil as the light component remains in the center of the separation cylinder 1 and enters the oil tank 11. The cutting fluid as the heavy component is separated to the outer layer through the drum 12 and discharged from the liquid outlet.
