The liquid separation assembly 9 and the discharge pipe 8 are detachably connected, which can be adapted to multiple separation barrels and has a wide application range.

[0043] The liquid separation assembly 9 includes a liquid separation pipe 903. A threaded sliding rod 904 is arranged in the liquid separation pipe 903. One end of the sliding rod 904 is connected to a cylinder 905 and the other end is provided with a liquid separation rubber ring. At least two liquid separation rubber rings are provided, namely a first liquid separation rubber ring 901 and a second liquid separation rubber ring 902. The number of the first liquid separation rubber ring 901 and the second liquid separation rubber ring 902 can be installed according to actual needs. In order to fix the positions of the first liquid separation rubber ring 901 and the second liquid separation rubber ring 902, nuts can be installed on their sides for fixation. An oil outlet pipe 906 is provided on one side of the liquid separation pipe 903 and a water outlet pipe 907 is provided on the other side. A mixed liquid chamber B is formed between the first liquid separation rubber ring 901 and the second liquid separation rubber ring 902. The side of the first liquid separation rubber ring 901 away from the mixed liquid chamber B is an oil chamber C, and the side of the second liquid separation rubber ring 902 away from the mixed liquid chamber B is a water chamber A. See Figure 3 When the sliding rod 904 is at the outermost end of the extended state, the mixed liquid chamber B communicates with the oil outlet pipe 906, and the water chamber A communicates with the discharge pipe 8 and the water outlet pipe 907; See Figure 2 When the sliding rod 904 is at the innermost end of the contracted state, the oil chamber C communicates with the discharge pipe 8 and the oil outlet pipe 906, and the mixed liquid chamber B communicates with the water outlet pipe 907.

[0045] During operation, the hydraulic cylinder 301 drives the cross plate 302 to descend. The adjusting rod 303 cooperates with it to drive the vertical cylinder 401 to move, and then drives the cylinder cover 501 to move to the mouth of the separation cylinder 1 for covering. The feed valve 504 is opened, and the liquid to be separated into oil and water enters the separation cylinder 1 through the feed pipe 503. An extraction agent is added, and the motor 402 is started. The operation of the motor 402 drives the rotating shaft 403 to rotate, thereby driving a plurality of stirring rods 404 to rotate. The plurality of stirring rods 404 stir the waste liquid and the extraction agent in the separation cylinder 1, and after the liquid to be separated into oil and water and the extraction agent are fully mixed, the oil and water are separated. When the separation of oil and water is completed, the water is located in the lower layer and the oil is located in the upper layer. The sliding rod 904 is extended to the farthest end. At this time, the discharge pipe 8, the water chamber A and the water outlet pipe 907 are communicated, and the water is discharged to the water collection device through the discharge pipe 8, the water chamber A and the water outlet pipe 907. See Figure 3 The staff observes the discharge situation of the water in the separation cylinder 1 through the viewing window 7. When the discharge of water ends, the sliding rod 904 is controlled to retract until the mixing liquid chamber B is communicated with the discharge pipe 8. The mixing liquid chamber B contains the mixing liquid at the contact surface of water and oil. See Figure 4 Then the sliding rod 904 is further retracted until the mixing liquid chamber B is communicated with the water outlet pipe 907. At this time, the mixing liquid in the mixing liquid chamber B is discharged through the water outlet pipe 907, and the oil is discharged to the oil collection device through the discharge pipe 8, the oil chamber C and the oil outlet pipe 906. See Figure 2 The mixing liquid discharged through the water outlet pipe 907 is connected to the return pipe 502 at the top of the cylinder cover 501 through a hose, and a control valve is also provided on the return pipe 502 to control the on-off. After the separation of oil and water in this time is completed, a new liquid to be separated into oil and water is injected, and at the same time, the control valve on the return pipe 502 is opened, and the mixing liquid stored in the hose and the mixing liquid chamber B is discharged into the separation cylinder 1 for a new round of oil-water separation. After all the oil-water separation work is completed, the oil adhering to the inner wall of the separation cylinder 1 can be scraped off by driving the cross plate 302 to rise by the hydraulic cylinder 301, and finally driving the filter screen plate 507 to rise, and the impurities filtered on the filter screen plate 507 are also removed outside the separation cylinder 1. After the staff replaces or cleans the filter screen plate 507, the hydraulic cylinder 301 drives the cross plate 302 to descend again, and finally moves the cylinder cover 501 to the mouth of the separation cylinder 1 for covering.

[0046] The utility model provides an oil-water separator convenient for recycling. Through the arrangement of the liquid separation assembly, the separated water and oil can be discharged respectively, improving the separation effect and facilitating classified recycling; through the arrangement of the cover body assembly, the impurities in the water and oil can be better filtered, ensuring the quality of the recycled water and oil; through the cooperation of the lifting assembly and the cover body assembly, the oil adhering to the inner wall of the separation cylinder can be better scraped off, avoiding oil residue.
