A drain pipe 18 is arranged below the side wall of the standing tank.
The bottom of the standing tank is provided with a drainage pipe 19 of the standing tank.
The water inlet pipe is provided with a medicine adding port 8.
The top of the air floatation tank is provided with an exhaust port 15.
Cutting fluid waste water passes through the inlet tube and gets into cyclone along cyclone peripheral tangential direction, makes it produce the attaches wall effect, and the arc guide plate makes waste water flow along the surface of guide plate, and the metal fillings in the waste water and other sediments are under the dual function of centrifugal force and the action of gravity that the whirl produced, sink to cyclone bottom from the lateral wall gradually, discharge through the row's cinder notch. The demulsifying agent is added in the cyclone separator, so that the demulsifying agent can be fully and uniformly mixed by utilizing the functions of cyclone and stirring. This is because the medicament needs a certain amount of time, space, and key driving force to mix after being added; meanwhile, the agent needs a certain time for acting after being added, and the agent is not consumed in the stage, but enters the next link, namely the air flotation tank along with water flow; in addition, the addition of the medicament also has a certain effect of assisting the sedimentation of metal scraps.
Then the cutting fluid wastewater flows into an air floatation tank, and reacts with a demulsifying agent in the air floatation tank, and the air floatation tank utilizes a dissolved air floatation technology to increase the turbulence of a system. The waste water that gets into the pond of stewing through the connecting pipe oil water separation gradually, the pond of stewing is discharged through the overflow weir to the light oil reservoir come-up, and lower floor's clarified water layer passes through the drain pipe and flows out. And the bottom sludge discharged from each treatment tank is discharged out of the treatment tank through a drain pipe in a self-flowing mode.

When the gyro wheel moves in the spout, the frizing stretches into below the liquid level and is used for scraping the showy oil reservoir in surface, and when the frizing moved the frizing slope, the frizing moved upward along the frizing slope under the drive of chain promoted the oil reservoir and upwards surpassed the frizing slope, flowed the pond of stewing through the oil drain port. The spout can carry out spacing and support to chain and frizing through the gyro wheel, prevents long-term practicality, and the droop can't be parallel with the liquid level below the chain.
The truss type slag scraping mode is completely abandoned, and sensor equipment is not needed. The power device only uses one motor, and the motor is fixedly installed in the area far away from the water surface, so that the device is simple, low in failure rate and easy to overhaul. Compared with the embodiment 1, the continuous oil scraping device of the embodiment can effectively hang the surface oil layer which is layered after cutting fluid wastewater is added with the medicament, and compared with the structure that an overflow weir easily flows out of a water layer, the oil removal is more thorough.
