Aluminum alloy powder production system provided with inert gas protective dust removing device

Abstract

An aluminum alloy powder production system provided with an inert gas protective dust removing device comprises an atomizing device, an atomizing chamber, a sleeve heat exchanger, a tubular heat exchanger, a centrifugal classifier, a cyclone classifier and a double-connection cyclone classifier which are sequentially connected, wherein a gas outlet pipeline of the double-connection cyclone classifier is divided into two branches; one branch is connected with an after-treatment system, and another branch is used as a dust removing system balancing pipe; a filter and a fire barrier are arranged on the dust removing system balancing pipe; the other end of the dust removing system balancing pipe is sequentially connected with a dust removing centrifugal classifier, a dust removing cyclone classifier and an efficient filter tank; the efficient filter tank communicates with a dust removing fan in a gas balancing tank. With the adoption of the production system, the potential risk of combustion and explosion can be effectively removed; in addition, dust product of which the particle size is uniformly distributed can be efficiently collected, so that the additional value of the product can be increased; meanwhile, the dust is not discharged to the outside at last, so that the problems of dust waste and environmental pollution can be further solved.

Description

technical field [0001] The invention relates to the field of powder metallurgy, in particular to an aluminum alloy powder production system with an inert gas (nitrogen) protection dust removal device. Background technique [0002] The existing fine spherical aluminum powder and aluminum-based alloy powder production packaging dust removal system is a front cyclone separator, its inlet is connected to the production system packaging dust removal material port, its outlet is connected to the inlet of the dust removal high-efficiency filter tank, and the outlet of the high-efficiency filter It is connected to the inlet of the flame retardant, and its outlet is connected to the inlet of the high-pressure centrifugal fan, and the outlet of the centrifugal fan is discharged to the outside. Its working process is to use the high-pressure centrifugal fan as the power to pre-separate the aluminum powder dust generated at the packaging outlet from the cyclone separator, and then perfo...

AI Technical Summary

Problems solved by technology

[0007] In view of the above problems, the present invention provides an aluminum alloy powder production system, which has a powder dedusting device protected by atmosphere circulation, which can effectively eliminate the above-mentioned potential safety hazards, and can efficiently collect dust products with uniform particle size distribution, increasing the product yield. Added value, at the same time, the dust is not discharged outside, which further solves the problems of dust waste and environmental pollution
