Tank door 303 and heating tank 3 are conveniently disassembled for inner wall cleaning, to avoid secondary pollution to subsequent quenching oil recovery.

[0022] In this embodiment, after the automobile leaf spring quenched from the quenching oil tank is taken out, the oil-water mixture after cooling and cleaning by the spraying device is introduced into the recovery tank 1 along the part between the recovery tank 1 and the slow flow plate 101, and the oil-water mixture impacts on the slow flow plate 101 and flows into the inside bottom end of the recovery tank 1 along the discharging channel 102 after buffering through the slow flow plate 101, so that the oil-water mixture can be quickly and stably separated, and the quenched oil floats on the water surface for subsequent separation. After the oil-water mixture in the recovery tank 1 is left for a period of time, the water is located at the inside bottom end of the recovery tank 1 and the quenched oil is located above the water to realize layering because the density value of the quenched oil is greater than that of water. The liquid level is monitored in real time by the liquid level sensor and the monitoring information is transmitted to the controller. At the same time, the controller starts the electromagnetic valve on the water pipe 201 to open the valve port and starts the pump body 202 to transport the water at the bottom into the water storage tank 2, so as to facilitate the recovery and treatment of the water. When the liquid level in the recovery tank 1 reaches the set minimum threshold value, there is still a small amount of water at the bottom of the quenched oil at this time. The pump body 202 and the electromagnetic valve on the water pipe 201 are closed. At this time, the electromagnetic valve port on the liquid inlet pipe 301 is opened by the controller. The quenched oil and a small amount of water flow into the heating tank 3 along the liquid inlet pipe 301. The heating wire in the middle layer of the heating tank 3 is heated to an appropriate temperature by the controller to heat the mixture in the heating tank 3. Because the boiling point value of water is lower than that of quenched oil, the water in the quenched oil will boil first. Hot gas is discharged from the exhaust pipe 302. After a certain period of time, the electromagnetic valve port on the oil discharge pipe 307 is opened to recover the purified quenched oil.
