A large amount of impurities are mixed in these industrial liquids, such as part rust preventives, machine tool lubricants, metal chips, etc. The long-term storage of industrial liquid will cause the liquid to deteriorate and produce pungent odors, which will affect people's physical health; too many impurities in the liquid will reduce the quality of the liquid, resulting in poor quality of processed parts. And high-quality processing liquid is expensive, and frequently replacing the processing liquid will increase production costs and cause a large amount of hazardous waste liquid to be generated. Therefore, most existing factories adopt the method of purifying and recycling the used industrial liquid.

The high-speed centrifugation method has a fast processing process, but high energy consumption, and the processing efficiency of floating oil or small particle impurities is not high, and it will damage the structure of the liquid and make it ineffective and unusable; the filter element filtration method has a complex process, a long purification time resulting in low purification efficiency, and the filter element consumables cost is high. Therefore, there is an urgent need to develop a new industrial liquid purification device. Summary of the Utility Model

Among them, the first filtration module filters metal impurities in industrial liquids, screens out impurities with larger particles and separates and removes them; the ultrasonic separation processing module can generate ultrasonic vibrations with specific frequencies, which are used to oscillate and separate the impurities and oil adhered and accumulated in industrial liquids to make them separate; the magnetic pole filtration module is mainly used for magnetic adsorption filtration of iron filings or other small metal particulate impurities suspended in industrial liquids; the ozone sterilization module can inject ozone into industrial liquids to kill pathogenic microorganisms such as bacteria and fungi in industrial liquids; the nano-aeration oil removal module adheres to fine impurities and floating oil in industrial liquids through the surface tension of nano-bubbles, so that the impurities and oil float on the top layer of industrial liquids and are then cleaned.

When the magnetic pole filtration module works, the magnetic roller remains in a rotating state, and magnetic adsorption of iron filings or other metal impurities in the industrial liquid is achieved through the magnetic roller. Since the scraper abuts against the bottom of the magnetic roller, the iron filings or other metal impurities adsorbed by the magnetic roller will be separated from the magnetic roller by the scraper during the rotation of the magnetic roller. The scraper is inclined, which can not only further limit the falling position of the iron filings or other metal impurities after separation, so that they can accurately fall into the slag box below the scraper, but also prevent the industrial liquid from entering the slag box.

[0021] As a preferred embodiment of the present utility model, a slag discharge port is provided on the side of the third outer shell, and the slag box is detachably connected to the slag discharge port. The slag discharge port is provided to facilitate the disassembly of the slag box and the cleaning of the iron filings or other metal impurities therein, thereby avoiding the normal function of the magnetic pole filtration module being affected due to excessive accumulation of iron filings or other metal impurities in the slag box.

At least two partition plates are arranged inside the fourth outer shell and the fifth outer shell. The arrangement of the partition plates can extend the path between the third liquid inlet and the third liquid outlet. Since the ozone sterilization module realizes the disinfection and sterilization effect by diffusing ozone into the industrial liquid through the high-density bubble tube, in order to ensure the best disinfection and sterilization effect, it is necessary to extend the diffusion time of ozone in the industrial liquid as much as possible.

The surface tension of the bubble film liquid is used to attach the impurities and oil suspended in the liquid, and then float to the upper part of the liquid and are separated by the oil removal device, solving the problem that the oil in the liquid is not thoroughly separated at present. Then, the oil removal device adopts an oil-blowing air knife, and the oil-blowing air knife blows out an air curtain irregularly to blow the oil foam and the surface-layered oil to the oil drainage area for collection and discharge. Finally, the treated liquid overflows to the liquid drainage area to complete the oil removal and impurity removal process.

The industrial liquid first enters the first filtration module 4 to filter large-particle impurities, and then is sequentially transported to the ultrasonic separation processing module 5 by the diaphragm pump to separate impurities and oil in the liquid, and then transported to the magnetic pole filtration module 6 for magnetic adsorption and removal of suspended small-particle impurities. Subsequently, the industrial liquid enters the ozone sterilization module 7 for disinfection and sterilization, and finally the industrial liquid enters the nano-aeration oil removal module for separation of miscellaneous oil, industrial liquid, and air flotation impurities. The industrial liquid is discharged from the liquid outlet 3 and recycled, and the impurity floating oil is collected separately.
