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 and method with a dust removal device protected by inert gas (nitrogen). 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, an...
