7. The water circulation equipment for producing the copper-based powder material by the water atomization method according to claim 1, which is characterized in that: atomizing chamber bottom end fixedly connected with sealed dish (9), sealed dish (9) and atomizing chamber outer chamber wall (201) are through U-shaped frame (5) coaxial fixed connection, and leave the annular gap between sealed dish (9) and the atomizing chamber outer chamber wall (201), sliding connection has row material ring (4) in the annular gap, arrange material ring (4) and U-shaped frame (5) and pass through sliding sleeve sliding connection, compression spring (1004) that cup joints on sliding sleeve bottom and U-shaped frame (5) are inconsistent.
8. The water circulation equipment for producing the copper-based powder material by the water atomization method according to claim 7, characterized in that: the bottom surface of the discharging ring (4) is inclined, the longitudinal section of the discharging ring (4) is L-shaped, and the inner side of the discharging ring (4) is attached to a sealing barrel fixedly connected with the bottom end of the sealing disk (9).
9. The circulation method of the water circulation equipment for producing the copper-based powder material by the water atomization method according to any one of claims 1 to 8, which is characterized in that: the method comprises the following steps:
1) the water in the water storage tank (1) is sprayed at high speed and high pressure by a water spraying disc (7) to act on the copper liquid discharged by a discharge pipe, so that the copper liquid is atomized, the water in the water storage tank (1) is discharged by a vertical curtain ring (8) to form an annular water curtain in an atomization cavity, and the copper liquid impacted by high-pressure water is prevented from impacting on the cavity wall (202) in the atomization cavity to cause deformation, so that the copper liquid which is not completely cooled after atomization is prevented from being adhered in the atomization cavity or deforming by impact;
2) the water in the water storage cavity is sprayed out through the horizontal curtain pipe (10) to form a horizontal water curtain, and the falling copper powder is continuously turned over under the impact of the water flow by the flowing water flow, so that the uniformity of the granularity is improved, and meanwhile, the falling copper powder is further cooled;
3) water flow flows through the return pipe (203) to flow back to the water storage tank (1) for recycling, meanwhile, a large amount of steam is formed after high-temperature copper liquid is contacted with water and is sent into the pneumatic mechanism (13) through the exhaust pipe (3) to drive the horizontal curtain pipe (10) to rotate, the horizontal curtain pipe (10) rotates at a high speed to enable the water flow in the atomizing cavity to rotate to generate centrifugal force, and copper powder in water is enabled to sink to the lower part of the atomizing cavity so as to be convenient for discharging the copper powder.
