The utility model principle: impurity-containing oil is input into the dirty oil area of the third oil drum; the first oil pump draws the dirty oil to the first oil drum, and the large particle impurities are deposited by standing; the first electromagnetic valve is opened, and the oil flows into the second oil drum for secondary sedimentation through the filter screen; the second oil pump draws the purified oil back to the clean oil area of the third oil drum, and the cycle is completed. Through multistage sedimentation, closed loop circulation and intelligent control, the problems of low efficiency and high energy consumption of the traditional oil pollution treatment device are solved.

[0005] As an improvement, the first oil drum, the second oil drum and the third oil drum are distributed in a triangular shape, the second oil drum and the third oil drum are at the same height, and the first oil drum is higher than the second oil drum and the third oil drum.

[0006] As an improvement, ultrasonic liquid level meters are arranged in the dirty oil area and the clean oil area of the first oil drum, the second oil drum and the third oil drum.

[0007] As an improvement, a blowdown port is arranged on the first oil drum, the second oil drum and the third oil drum, and a second electromagnetic valve is arranged at the blowdown port.

[0008] The utility model compared with prior art brings the beneficial effect is:

[0009] Through multi-stage sedimentation, closed-loop circulation, and intelligent control, the problem of low efficiency and high energy consumption of traditional oil pollution treatment devices has been solved. It is particularly suitable for the continuous purification needs of industrial scenarios such as machine tool cutting oil and hydraulic oil. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the present invention.

[0011] Figure 2 This is a pipeline diagram of this utility model. Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] like Figure 1 , 2 As shown, an oil sludge sedimentation device includes a first oil drum 1, a second oil drum 2, and a third oil drum 3, which are arranged in a triangular pattern. The second oil drum 2 and the third oil drum 3 are at the same height, while the first oil drum 1 is higher than the second oil drum 2 and the third oil drum 3. The first oil drum 1 has a capacity of 200L, the second oil drum 2 has a capacity of 150L, ​​and the third oil drum 3 has a capacity of 300L. Different capacities of oil drums can be set according to actual production needs. The third oil drum 3 is equipped with a partition 31, which divides the interior of the third oil drum 3 into two halves: a sludge oil area 32 and a clean oil area 33. A first oil pipe 7 is provided between the first oil drum 1 and the third oil drum 3. A first oil pump pumps oil from the sludge oil area 32 in the third oil drum 3 to the first oil drum 1 through the first oil pipe 7. A second oil pipe 8 is provided between the first oil drum 1 and the second oil drum 2. A first solenoid valve 5 is installed on the second oil pipe 8. The oil in the first oil drum 1 is transported to the second oil drum 2 through the second oil pipe 8 under its own gravity. A third oil pipe 9 is provided between the second oil drum 2 and the third oil drum 3. A second oil pump 6 pumps the oil in the second oil drum 2 to the clean oil zone 33 of the third oil drum 3 through the third oil pipe 9. Ultrasonic level gauges are installed in the sludge zone 32 and clean oil zone 33 of the first oil drum 1, the second oil drum 2, and the third oil drum 3.
