It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] As Figure 1 shown, a cutting fluid supply and purification system includes a delivery pump 1, a collection tank 2, an oil skimming device 3, a filter membrane filtration device 4 and a product water tank 5. The delivery pump 1 transports the cutting fluid from the production line to the collection tank 2, and then transports the cutting fluid in the collection tank 2 to the oil skimming device 3 through the delivery pump 1. The oil skimming device 3 disinfects the cutting fluid from the production line and separates and recovers the high-concentration floating oil and cutting floating slag in the cutting fluid from the production line. Then, the cutting fluid in the oil skimming device 3 is transported to the filter membrane filtration device 4 through the delivery pump 1. The filter membrane filtration device 4 separates the solid suspended matter in the cutting fluid, and transports the remaining liquid to the product water tank 5 through the delivery pump 1 to recover the cutting fluid.

A placement chamber 312, a disinfection chamber 311 and a separation chamber 313 are provided on the frame 31. The placement chamber 312 and the disinfection chamber 311 are arranged above the separation chamber 313. The oil skimming mechanism 33 and the bubble generating mechanism 34 are installed in the separation chamber 313. The control drain pipe 36 connects the disinfection chamber 311 and the separation chamber 313. The feed inlet 35 connects the disinfection chamber 311 with the outside. The blanking mechanism 37 connects the separation chamber 313 with the outside. The disinfection mechanism 32 is installed in the placement chamber 312 to disinfect the cutting fluid in the disinfection chamber 311. In this embodiment, the disinfection mechanism 32 can be a UV sterilization device or an ozone sterilization device. After the sterilization is completed, the cutting fluid is transported from the disinfection chamber 311 to the separation chamber 313 through the control drain pipe 36. The bubble generating mechanism 34 transports bubbles into the cutting fluid in the separation chamber 313, so that the suspended matter adheres to the bubbles and rises to the water surface. The oil skimming mechanism 33 adsorbs and collects the suspended matter floating on the cutting fluid, and the blanking mechanism 37 discharges the cutting fluid after the separation is completed.

[0023] The bubble generating mechanism 34 includes a micro-nano bubble generator 341, an air pipe 342, and a bubble disk 343.

The micro-nano bubble generator 341 is installed in the placement chamber 312. A plurality of bubble outlets are arranged in an orderly manner on the upper surface of the bubble disk 343. The micro-nano bubble generator 341 generates micro-nano bubbles, which are transported to the bubble disk 343 through the air pipe 342 and emitted from the bubble outlets, enabling the suspended substances to attach to the bubbles and rise to the water surface, thereby separating the cutting fluid and the suspended substances.

[0024] The floating oil adsorption mechanism 33 includes a floating oil pump 334, a foam board 332, a liquid level sensor 333, and a lifting guide rod 331. The foam board 332 is fixedly arranged at the end of the lifting guide rod 331. The floating oil pump 334 and the liquid level sensor 333 are installed on the foam board 332. The liquid level sensor 333 senses the liquid level position of the cutting fluid. The lifting guide rod 331 drives the foam board 332 to move, so that the foam board 332 remains on the liquid surface of the cutting fluid. The floating oil pump 334 adsorbs and collects the suspended substances on the liquid surface of the cutting fluid.

[0025] The blanking mechanism 37 includes a blanking water pump 372 and a blanking pipe 371. The blanking pipe 371 is communicated with the blanking water pump 372 and is also communicated with the lower end of the separation chamber 313.
