For the convenience of understanding the technical solution of the present invention, the following detailed description is made on the working principle or the operation mode of the present invention in the practical process.

During practical application, through making two independent 380L volumetric circular water tanks, divide into fatlute collecting box 4 (foul solution case) and purifying box 3, two liquid tanks all have heating and thermostatic control function. The two liquid tanks have stirring function, and the stirring rod is provided with two upward spiral impellers and a mouth-shaped stirring scraper below the stirring rod according to pictures. The two liquid tanks are provided with three-point level gauges 16, and the outlets of the two liquid tanks are respectively provided with a flow switch, a pump and an electromagnetic valve;

the oil sludge (oil/liquid/impurity mixture) separated by the rolling mill magnetic separator 12 overflows into the oil sludge collection box 4 through high-low head, the heating device is always started to work, and the temperature of the mixed liquid is kept between 50 and 60 ℃;

when the liquid in the dirty liquid tank reaches a low liquid level (200L is adjustable), the liquid level switch gives a signal to start the first diaphragm pump 18, the emulsified liquid in the water tank of the emulsified liquid rolling mill is supplemented into the dirty liquid collecting tank 4, and when the liquid level reaches 300L, the liquid level sensor closes the first electromagnetic valve 20 (the electromagnetic valve is a normally closed electromagnetic valve) and the first diaphragm pump 18 air inlet electromagnetic valve (the electromagnetic valve is a normally closed electromagnetic valve). Remarking: the high liquid level of the dirty liquid tank is 350L of alarm liquid level, when the high liquid level reaches the alarm liquid level, the system gives an audible and visual alarm and closes the electromagnetic valve of the emulsion inlet pipeline and the electromagnetic valve of the diaphragm pump air inlet at the same time, so that the liquid leakage accident caused by the failure of the high liquid level is avoided;

when the dirty liquid collecting box 4 reaches 300 liters of medium liquid level, the system starts a stirrer to work for 5-10 minutes, after the two liquids are fully stirred, a second diaphragm pump 25 arranged at an outlet at the bottom of the dirty liquid collecting box is started to pump all the 300 liters of liquid into the purifying box 3, a pulse flowmeter is arranged outside a pipeline of the second diaphragm pump 25, after the 300L of liquid is exhausted, the flowmeter gives a signal to the system, the system delays for one minute to close the second diaphragm pump 25, and the liquid is ensured not to be stored in the pipeline as far as possible. Remarking: the pipeline is proposed to be vertically lifted after coming out from an outlet at the bottom of the dirty liquid tank, and then overflows to the purification tank 3 after reaching the height higher than the top of the purification tank 3, so that the position of the pipeline possibly blocked by oil cooling is only a vertical part, whether the pipeline needs to be provided with a pipeline heating function or not is determined according to the situation, and the possibility of blockage is small due to the gradient and the pressure of the pump in the overflow part;

when the liquid in the dirty liquid tank is pumped to the low liquid level (200L) of the purification tank 3, the low liquid level gives a signal to start the centrifugal machine to work simultaneously with the heating function and the stirring function, the centrifugal machine pumps the liquid from the bottom of the purification tank 3, the liquid returns from the top, and the circulation purification is started in the purification tank 3 for 24 hours. The liquid level and the high liquid level in the purifying box 3 are both protective liquid levels, the set heights are 320/350L respectively, and when the liquid level reaches 320/350L due to the fact that the purifying box 3 cannot be emptied in time if the third diaphragm pump 30 is damaged or the dirty liquid box is filled with 200L more than the centrifugal emptying time of the purifying box 3, the system can shut down the second diaphragm pump 25 of the dirty liquid box and give an alarm, and liquid leakage accidents are avoided;

when the circulation purification is finished for 24 hours (the time can be adjusted according to the dirty liquid cleaning), the automatic deslagging rotor purifier 1 stops running, a diaphragm pump III 30 arranged at the bottom of the purification box 3 is started up, and all liquid in the purification box 3 is pumped into a large liquid box of an emulsion rolling mill for use. The liquid pumping pipeline is also provided with a pulse flowmeter, and when the pump is evacuated, the electromagnetic valve of the gas circuit of the diaphragm pump is closed, and the whole cycle is ended.

The principle of centrifugation adopted by the automatic slag removal rotor purifier 1 is that centrifugation is a method for separating, concentrating and purifying a dirty liquid by utilizing centrifugal force of rotary motion and difference of sedimentation coefficient or suspension density of substances. The rotor rotates at a high speed to generate strong centrifugal force, so that liquid in the dirty liquid is separated from solid particles, the solid particles are remained on the inner wall of the rotary drum 40, and the liquid is discharged from the liquid outlet;

automatic arrange sediment rotor clearing machine 1 and get into centrifuge drum 40 from the inlet through the auxiliary pump with pending liquid, impurity in the dirty liquid is by high-speed separation, adhere to around the drum 40 inner wall, liquid after the processing is arranged back to the circulation groove again, after equipment operation certain time, equipment starts automatic slag removal function row cinder notch and opens, equipment automatic disconnection and main shaft motor 34 transmission, connect simultaneously and scrape sediment motor 49 and operate, built-in scraper 39 begins to move and advances the slagging-off, the impurity of cleaing off falls into the impurity collecting vat of equipment below from the cinder notch, accomplish the effect of automatic sediment of arranging.

To sum up, with the help of the utility model discloses an above-mentioned technical scheme, carry out certain decrement through letting the fatlute that magnetic separator 12 separated on the rolling mill, the sediment of coming out is semi-solid, reduces its treatment cost, and the emulsion after falling fatlute through the separation can return emulsion pond mesocycle use with rolling oil, practices thrift the use cost of rolling oil, the utility model discloses a purify the full automatic operation of decrement system, automatic collection, thoughtlessly join in marriage, purify, shut down, clean fluid returns, has very high practicality.

The above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
