Description

Technical Field

[0001] This application relates to the technical field of plasma rotating electrode powder-making equipment, and particularly to a dynamic seal disassembly and assembly auxiliary mechanism for plasma rotating electrode powder-making equipment. Background Technique

[0002] The Plasma Rotating Electrode Process (PREP) is a method for preparing metal powders. Its principle is mainly that in an atomization chamber, a metal rod serves as a consumable electrode and melts under plasma, while the electrode is kept rotating at a high speed. Therefore, the generated metal liquid is thrown out by centrifugal force, forming fine droplets, and cooling and solidifying into spherical particles in an argon environment. The metal powders prepared by PREP have the advantages of high sphericity, few satellite powders, and almost no hollow powders, and can be applied to multiple industrial fields.

[0003] In the actual work of preparing powders, powder preparation tasks of different metals are often encountered. When switching metals, it is necessary to comprehensively clean the powder-making cavity and the dynamic seal system to prevent the previous metal powders from mixing into the new metal powder system and affecting the powder quality. The main function of the dynamic seal system is to isolate the atomization chamber from the outside air and ensure the powder quality. Its components include a front dynamic seal plate, a rear dynamic seal plate, and other auxiliary parts. When cleaning the powders, it is necessary to remove both the front and rear dynamic seal plates to prevent powders from existing in the gaps. However, the front and rear dynamic seal plates are relatively heavy, and it is difficult for a single person to independently disassemble them. Disassembly by two people is also time-consuming and laborious, seriously affecting work efficiency and posing a potential risk of heavy parts falling and damaging or injuring the personal safety of the staff.
