Problems solved by technology

[0003] At present, zinc powder is still prone to energy waste in the production process, and at the same time, the output efficiency is not high, the cycle of putting the device into production is long, and the refinement rate is low, which requires high raw materials.
In the event of a failure, zero output during maintenance, resulting in wasted energy and low economic efficiency

Abstract

The invention discloses a co-production type metal powder preparation device, and relates to the field of industrial production, and the device comprises a distillation heating unit, a side purification furnace unit, a waste heat collection unit and a smoke emission unit which are arranged in sequence. Wherein the distillation heating unit comprises a heating bin, an ignition, gas valve and temperature feedback control integrated device positioned at the lower part of the heating bin, and a condenser and powder screening module integrated device; and the side purification furnace unit comprises a melting furnace and a medium-rotating furnace. The melting furnace is connected with the intermediate converter through a liquid flow guide pipe, and the distillation heating unit is connected with the intermediate converter through a flow guide pipe. Waste heat generated by the heating bin is connected into the waste heat collecting unit and serves as a heat source for air heating. According to the method, high zinc powder production yield, short production period, low raw material requirement, low loss and high maintenance speed can be achieved, the evaporation device can be recycled, energy conservation and environmental protection are achieved, and the fine powder rate can reach 90-95% when the fine powder rate is 400 meshes or above according to practice.

Description

technical field [0001] The technology of the invention relates to the field of industrial production, and specifically designs a co-production type metal powder preparation device. Background technique [0002] Zinc powder is an important industrial basic raw material. Its uses can include zinc powder for metallurgical reduction, zinc powder for new energy, zinc powder for anti-corrosion, etc. It is widely used in automobiles, construction, home appliances, light industry, machinery, batteries and other industries. With the development of my country's industry, the consumption of zinc has gradually increased, and it is currently second only to copper and aluminum in the consumption of non-ferrous metals. However, the basic reserves of zinc mines in my country are relatively small, accounting for less than 20% of the global proportion, and there are few rich ores and large mines. The net export trade shows a clear deficit. 2021-2026 China Nonferrous Metals Industry Market Pro...
