High-activity metal smoke dust treatment system

Abstract

The invention discloses a high-activity metal smoke dust treatment system which comprises a smoke dust collector, two filtering pipelines and a pipeline switching component; the smoke dust collector comprises a pair of funnel-shaped smoke collecting heads, the funnel-shaped smoke collecting heads are symmetrically arranged on the two sides of the lower portion of the laser head and fixed to a flange plate of the laser head through smoke dust collecting pipelines, and the smoke dust collecting pipelines are communicated with the two filtering pipelines respectively. A metal net cover is arranged in the funnel of the funnel-shaped smoke dust collecting heads; the two filtering pipelines are converged through a Y-shaped pipeline and then are communicated with the outside through a pipeline, and the pipeline switching part is arranged at the intersection point of the Y-shaped pipeline. The funnel-shaped smoke dust collecting heads are arranged on the two sides of the laser head, so that metal smoke dust condensed after melting in the additive manufacturing process can be effectively collected, and the liquidity and stability of the molten pool is not affected.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing of metal materials, in particular to a highly active metal fume treatment system generated in the process of metal 3D printing and welding. Background technique [0002] In the process of metal 3D printing and welding, it is usually accompanied by the generation of metal fumes. Metal powders are melted under the action of high-energy laser beams and generate metal vapors (often including several elements such as Fe, Mn, Si, Cr, Ni, etc.) ) rapidly condenses and oxidizes in the air to form solid particles with a diameter of less than 0.1 microns, which are called smoke, and metal particles with a diameter of 0.1-10 microns are called metal dust, collectively referred to as metal soot. [0003] Long-term inhalation of high concentrations of metal fumes can cause various serious organic changes in the human respiratory system and nervous system. If long-term inhalation of mixed smoke ...

Problems solved by technology

At the same time, metal fume is also easy to adhere to the surface of the equipment, such as the surface of the laser lens to form pollution and damage the equipment

[0004] Therefore, the comprehensive prevention and control of smoke and dust can not only protect the lives and health of the people, protect processing equipment, but also promote the upgrading of my country's metallurgical industry, release the industry's production potential, and improve the comprehensive utilization efficiency of resources. However, traditional smoke and dust treatment is time-consuming. long and inconvenient
