the wire rod which needs to remove the surface oxide skin derusts in the wire rod derusting nozzle, and the method specifically comprises the following steps: the wire rod enters the first mixing cavity 1 from the wire inlet channel 6 and passes out of the first mixing cavity 1 from the wire outlet channel 7; after the wire rod enters the first mixing cavity 1, the high-pressure water spraying device and the sand inlet structure are started, and high-pressure water flow enters the annular water inlet groove 8 from the water inlet pipe; one end of the water spraying hole 3 is communicated with the annular water inlet groove 8, and the other end of the water spraying hole is communicated with the first mixing cavity 1, so that high-pressure water flow enters the annular water inlet groove 8 and then enters the first mixing cavity 1 through the water spraying hole 3, and meanwhile, sand blasting enters the first mixing cavity 1 from the sand inlet 17; after entering the first mixing cavity 1, high-pressure water flow drives sand blasting to move at a high speed, and as a plurality of water spraying holes 3 are arranged and the plurality of water spraying holes 3 are distributed along the circumferential direction, the whole circumferential surface of the wire rod is filled with a water and sand mixed solution which moves at a high speed, so that the iron oxide scale on the surface of the whole wire rod can be thoroughly removed; the water and sand mixed liquid which is uniformly mixed in the first mixing cavity 1 flows out from the second mixing cavity at a high speed, and the second mixing cavity is formed between the outer side of the wire rod and the inner wall of the wire inlet channel 6, so that the whole surface of the wire rod is filled with the uniformly mixed liquid of high-speed water flow and sand blasting, the flowing direction of the mixed liquid is opposite to the direction of the wire rod entering the wire rod rust removal nozzle, and the surface of the wire rod before entering the first mixing cavity 1 is subjected to pre-rust removal treatment.
The present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents and are included in the scope of the present invention.
