Problems solved by technology

The traditional structural design of water atomization nozzles can only produce irregular (or elliptical, teardrop-shaped (or quasi-spherical)) powders, and cannot produce spherical (from whole to individuals are spherical) metal powder
The annular seam nozzle of the water atomization nozzle is difficult to process, the combined mold structure requires high requirements for installation, and the concentricity is too low, resulting in uneven distribution and non-focus of the atomization medium, and effective atomization cannot be carried out.

Abstract

The present invention relates to jet device for water atomized metal powder producing line, and provides jet device for water atomized spherical metal powder producing line and with low cost and easy maintenance. The jet device has spray nozzle body with 4-8 water jets set on the horn wall, and each of the water jets has a nozzle with elliptic hole stretched beyond the end of the horn. The improved device can produce spherical metal powder with fine powder of 30 micron size over 65%. Compared with available technology, the present invention has the advantages of low investment, simplified technological process and easy operation.

Description

technical field [0001] The invention relates to a spraying device on a water atomized metal powder production line. Background technique [0002] Non-ferrous metal powder making methods include atomization method, which belongs to mechanical powder making method. This method uses direct crushing of liquid metal or alloy to make powder. The atomization method includes the two-flow atomization method, which is divided into gas atomization and water atomization. For the traditional production method of spherical metal powder (including copper and copper alloy powder), inert gas atomization is adopted, and the annular nozzle is used. The inert gas manufacturing equipment in the process is expensive and the environmental protection requirements are high. The height of the factory building is more than 14m, and the fog The tank should be more than 7m, and the atomization device requires no leakage, and there must be a dust collection device, etc. Another major disadvantage is th...
