System for producing zinc powder by hydraulic atomization

Abstract

The invention discloses a system for producing zinc powder by hydraulic atomization. The system comprises a cored induction electric furnace, a dust removal device, a heat insulation leakage package,an atomization device, a screening filter device and a waste water recovery device. A zinc plate feeding opening and a zinc grain feeding opening are formed in a cover of the core induction electric furnace, a smoke and dust box is arranged on the zinc plate feeding opening, an inverted baffle plate is arranged on one side of the smoke and dust box, and zinc plates are laid on the furnace wall ofthe inner side of the cored induction electric furnace; a zinc melt liquid outlet is connected to an electrothermal diversion groove, and flow restricting rock wool and a flow baffle plate are arranged at the front end of the electrothermal diversion groove; the atomization device includes a water storage tank and an atomization tank, and the water storage tank is communicated with an atomizationnozzle through a high pressure hose and a high pressure pump; the waste water recovery device includes a filter and a cooling tower. According to the system, the process controllability is excellent,the efficiency is high, the performance of zinc powder produced is great, waste water produced in the preparation process by hydraulic atomization is effectively treated and recycled, water resourcesare save, the cost is reduced, and the system is safe and reliable without environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of nonferrous metal materials, in particular to a production system of hydraulic atomized zinc powder. Background technique [0002] Zinc powder is used as a replacement agent in the purification process of zinc hydrometallurgy. Many zinc hydrometallurgy plants have attached zinc powder manufacturing workshops to produce zinc powder for self-use. The metal zinc powder produced by the hydraulic atomization method has fine particle size, large specific surface area, and low oxidation rate, so the production of metal zinc powder by the hydraulic atomization method has begun to be widely used by wet zinc smelting enterprises. [0003] The existing hydraulic atomized zinc powder production system includes a zinc melting furnace, a heat preservation leakage bag, an atomizer, a filter device, and a waste water recovery device. Due to the relatively short application time of this technology, there are still many sho...

Problems solved by technology

[0003] The existing hydraulic atomized zinc powder production system includes a zinc melting furnace, a thermal insulation leakage bag, an atomizer, a filter device, and a waste water recovery device. Due to the relatively short application time of this technology, there are still many shortcomings in the production system, such as : The feeding port of the zinc plate is relatively large, the splash of molten zinc during the feeding process is easy to burn people, the adhesion on the inner surface of the furnace wall is not easy to clean, and the noise generated by the high-pressure pump pipeline of the seamless steel pipe is large, etc.
