[0002] A steel pipe is a steel product with a hollow cross-section, and its length is much greater than its diameter or circumference. It is divided into round, square, rectangular and special-shaped steel pipes according to the cross-sectional shape; it is divided into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes and composite steel pipes according to the material; it is divided into steel pipes for conveying pipelines, engineering structures, thermal equipment, petrochemical industries, mechanical manufacturing, geological drilling, high-pressure equipment, etc. according to the use; it is divided into seamless steel pipes and welded steel pipes according to the production process. Among them, seamless steel pipes are further divided into hot-rolled and cold-rolled (drawn) types, and welded steel pipes are further divided into straight-seam welded steel pipes and spiral-seam welded steel pipes. When processing steel pipes, since the surface is coated with rust preventive oil, it is necessary to first use a degreasing device to remove the oil.

An oil remover storage tank 302 is fixedly provided at the rear end of the upper end of the C-shaped bracket 2. Two parallel limiting rings 4 are fixedly connected to the middle between the inner side of the C-shaped bracket 2 and the inside of the degreasing device 1. A rotating ring 401 is rotatably connected between the two limiting rings 4. A driving motor 5 for driving the rotating ring 401 to rotate is fixedly provided at the inner upper end of the C-shaped bracket 2. A plurality of elastic brush rods 403 are annularly arranged on the inner end face of the rotating ring 401. An annular pressure water pipe 6 is fixedly provided at the front middle between the inner side of the C-shaped bracket 2 and the inside of the degreasing device 1. A plurality of nozzles 601 are fixedly connected annularly inside the annular pressure water pipe 6. A water tank 604 for supplying water to the annular pressure water pipe 6 is fixedly provided at the upper end of the C-shaped bracket 2.

[0024] Further, clamping grooves 103 are provided on the support rollers 102, and a sewage outlet 104 is provided at the lower end of one side end face of the degreasing device 1.

[0025] Further, the upper end of the metering pump 3 is connected to the inside of the oil remover storage tank 302 through a liquid supply pipe. The steel pipe is inserted into the degreasing device 1 from the rear semi-circular opening 101 through a conveying device. The steel pipe is supported by the support rollers 102, and at the same time, the steel pipe is clamped by the clamping grooves 103.

[0026] Further, both the limiting rings 4 and the annular pressure water pipe 6 are fixedly connected to the inner end face of the C-shaped bracket 2 through support rods. When the steel pipe extends forward into the lower end of the C-shaped bracket 2, first, the metering pump 3 drops the oil remover in the oil remover storage tank 302 onto the upper end face of the steel pipe through the drip pipe 301. The steel pipe with the dropped oil remover continues to move forward through the middle of the rotating ring 401.

[0027] Further, a turbine tooth 402 is fixedly provided in the middle of the outer end face of the rotating ring 401, and a worm 501 is fixedly connected to the output shaft of the driving motor 5.

[0028] Further, the turbine tooth 402 on the rotating ring 401 extends out between the two limiting rings 4 and meshes with the tooth part of the worm 501 on the output shaft of the driving motor 5. The driving motor 5 drives the worm 501 to rotate, thereby driving the rotating ring 401 to rotate between the two limiting rings 4, so that a plurality of elastic brush rods 403 annularly arranged on the inner side of the rotating ring 401 brush the outer surface of the steel pipe, and at the same time, the oil remover is evenly brushed on the outer surface of the steel pipe, and the oil remover is used to comprehensively degrease the outer surface of the steel pipe.

[0030] Working principle: During use, the steel pipe is inserted into the rear semi-circular opening 101 of the degreasing device 1 through the conveying device. The steel pipe is supported by the support rollers 102, and at the same time, the steel pipe is positioned by the clamping groove 103. When the steel pipe extends forward into the lower end of the C-shaped bracket 2, first, the metering pump 3 drops the degreasing agent in the degreasing agent storage tank 302 onto the upper end surface of the steel pipe through the dropper 301. The steel pipe with the degreasing agent dropped on it continues to pass forward through the middle of the rotating ring 401. The driving motor 5 drives the worm 501 to rotate, and then drives the rotating ring 401 to rotate between the two limiting rings 4, so that the multiple elastic brush rods 403 arranged in an annular array on the inner side of the rotating ring 401 scrub the outer surface of the steel pipe, and at the same time, the degreasing agent is evenly brushed on the outer surface of the steel pipe synchronously, using the degreasing agent to perform overall degreasing on the outer surface of the steel pipe. The steel pipe scrubbed by the elastic brush rod 403 continues to pass forward through the middle of the annular pressure water pipe 6. The booster pump 603 pressurizes and supplies the clear water in the water tank 604 to the annular pressure water pipe 6 through the water supply pipe 602, so that the clear water in the annular pressure water pipe 6 sprays out from the nozzle 601 to perform high-pressure flushing on the stains on the surface of the steel pipe after degreasing with the degreasing agent, realizing the overall degreasing of the steel pipe.
