The steel pipe is coaxial with the circular through hole 21 when inserted, and the steel pipe passes through a plurality of circular rubber rings 22 in turn and enters the inner tube of the nozzle 51 to wash away the residual oil stains. After the cleaning liquid sprayed by the nozzle 51 cleans the steel pipe, the cleaning liquid is drained into the water tank 53 through the support rod 5101, and the cleaning liquid in the water tank 53 is filtered by the oil stain filter 521 and then transported to the nozzle 51 by the water pump 522. For steel pipes of different specifications, it is only necessary to replace the second rectangular body 2 of the circular through holes 21 of different specifications.

[0020] The present invention uses a plurality of circular rubber rings 22 to remove the oil stains on the steel pipe and then uses a spray device 5 to clean the remaining oil stains, so that no oil stains are left on the steel pipe while recovering the rolling oil; the inner diameters of the plurality of circular rubber rings 22 gradually decrease from the rightmost circular rubber ring 22 to the leftmost circular rubber ring 22, and the less oil stains on the steel pipe, the greater the pressure applied by the circular rubber rings 22 on the steel pipe is required to scrape off the oil stains on the steel pipe to the maximum extent; the second rectangular body 2 and the first rectangular body 1 are fixed by a hand-tightened screw 126, and the second rectangular body 2 and the first rectangular body 1 are convenient to combine and separate, and the second rectangular body 2 with round through holes 21 of different specifications can be replaced in a portable manner to adapt to steel pipes of different specifications; the first oil guide groove 1101 and the second oil guide pipe 1101 cooperate to guide the recovered oil into the oil storage container 3, and the oil outlet through hole 23 and the first oil guide pipe 2301 cooperate The recovered oil is introduced into the oil storage container 3, and the oil outlet hole 23 can prevent the rolling oil from gathering in the round hole 21. The gathering of rolling oil in the round hole 21 will increase the pressure on the annular rubber ring 22, and then the sealing between the annular rubber ring 22 and the steel pipe will deteriorate, making the oil scraping efficiency of the annular rubber ring 22 lower; since the steel pipe is scraped by several annular rubber rings 22, there is very little oil stain remaining on the steel pipe. At this time, the consumption of cleaning liquid by the spray device 5 is low, and since there is very little oil stain, the oil stain filter 521 can easily filter the oil stain and the consumption of the filter element is low; the first oil stain detector 401 can monitor the thickness of the residual oil stain on the steel pipe at the left port of the first through hole 11, which is beneficial to monitor the wear state of the annular rubber ring 22; the second oil stain detector 402 can monitor the oil stain thickness of the finished steel pipe to ensure that the finished product is free of oil stain, and at the same time it is beneficial to monitor the working state of the spray device 5.
