Anti-blocking atomizer nozzle for preparing micro-fine metal powder and anti-blocking method thereof

Abstract

The invention relates to an anti-blocking atomizer nozzle for preparing micro-fine metal powder and an anti-blocking method thereof. The anti-blocking atomizer nozzle comprises a nozzle inner body; a guide pipe is arranged in the nozzle inner body; an air cavity is formed between the nozzle inner body and a nozzle outer body; the nozzle inner body and the nozzle outer body form a spray pipe structure at a spout of the guide pipe; the guide pipe is connected with a power supply cathode; the center of the guide pipe is provided with a composite electrode bar; the composite electrode bar comprises a first electrode and a second electrode; the first electrode and the second electrode are connected with two power supply anodes respectively; an insulating block is arranged between the first electrode and the second electrode; and the second electrode and the inner wall of the guide pipe form a melt flow passage. The composite electrode bar is increased in the guide pipe; when blocking happens, the composite electrode bar and the guide pipe are switched on to heat a blocking object and melt the blocking object instantaneously so as to fulfill the purposes of preventing and solving the blocking, continue the production of the metal powder, ensure smooth operation of the production and improve the production efficiency of an enterprise.

Description

Technical field: [0001] The invention belongs to the technical field of producing superfine powder by gas atomized molten liquid, and in particular relates to an anti-clogging atomizer nozzle and an anti-clogging method for preparing fine metal powder. Background technique: [0002] The double-flow atomization method is the main method of producing metal powder. The principle of powder making is: a high-speed fluid impacts the metal liquid to break the liquid metal into fine powder and rapidly cools and solidifies to form metal powder. In this method, the atomizer is the necessary equipment, and it is the core of the technology of producing metal powder by the double-flow method. When there is a problem with the atomizer, the production will not be able to proceed, and the production must be stopped for maintenance. The atomizer is in accordance with the structure of its nozzle. It is divided into annular hole type atomizer or annular seam type atomizer. For any structure of...
