[0003] In the prior art, oil and water are separated by stirring. Due to its density, the oil is usually located on the surface of the water. Under the action of centrifugal force, the liquid level near the inner wall of the separation cylinder is usually higher than the liquid level at its center. The position of the oil extraction port is difficult to adjust in real time with the liquid level. A brief separation may occur and the oil cannot be extracted. The displacement of the oil extraction port is completely dependent on the push cylinder. The position of the oil extraction port needs to be controlled and adjusted in real time, which is not conducive to later maintenance. There is room for optimization of the oil extraction method.

The connecting seat 20 forms an annular structure, and the stirring rod passes through the hollow part of the connecting seat 20 and extends to the inner bottom surface of the separation cylinder 10. The stirring rod has a vertical axis and a cross bar, and the cross bar is fixedly connected to the vertical axis. The cross bar is located below the connecting seat 20, and the oil extraction body 23 forms a hollow spherical structure. The circumferential surface of the oil extracting body 23 is provided with oil extracting holes, which are distributed vertically downward. In this scheme, the motor drives the stirring shaft to rotate so that the oil-water mixture in the separation cylinder 10 is stratified. At the same time, the mixture will also approach the inner wall of the separation cylinder 10 under the action of centrifugation, that is, the liquid level at the inner wall of the separation cylinder 10 will be higher than the liquid level at the center of the separation cylinder 10. By setting the first flip rod 22 and the second flip rod 26, the length of the first flip rod 22 is greater than the length of the second flip rod 26, so the oil extracting body 23 at the bottom of the first flip rod 22 is used to extract the oil near the inner wall of the separation cylinder 10. Liquid, the oil extraction body 23 at the bottom of the second flip rod 26 is used to extract oil near the center of the separation cylinder 10. The bottom port of the oil extraction pipe 12 is fixedly connected with a plug. The two oil extraction bodies 23 are connected to the oil extraction pipe 12 through pipelines and the plugs are inserted into the plugs. The oil floating in the separation cylinder 10 can be extracted through the oil extraction pipe 12. The slidable oil extraction body 23 can adjust its position as the liquid level changes, and then adapt to the different liquid level heights caused by centrifugal action, so as to better extract oil and improve separation efficiency.

The electric cylinder 31 pushes the side plate 30 to drive the connecting seat 20 to rise and fall, thereby further improving the vertical displacement stroke of the oil extraction body 23 to adapt to changes in the oil.

[0029] The working principle of the utility model is as follows: the motor drives the stirring shaft to rotate so that the oil-water mixture in the separation cylinder 10 is separated into layers, and at the same time, the mixture will also approach the inner wall of the separation cylinder 10 under the action of centrifugation, that is, the liquid level at the inner wall of the separation cylinder 10 will be higher than the liquid level at the center of the separation cylinder 10. By setting the first flip rod 22 and the second flip rod 26, the length of the first flip rod 22 is greater than the length of the second flip rod 26, then the oil extractor 23 at the bottom of the first flip rod 22 is used to extract the oil near the inner wall of the separation cylinder 10, and the oil extractor 23 at the bottom of the second flip rod 26 is used to extract the oil near the center of the separation cylinder 10.
