Indium powder manufacturing system

Abstract

The invention relates to an indium powder manufacturing system which comprises a melting tank for liquefied indium raw material, wherein a flow guiding pipe for guiding the liquid indium is arranged at one side of the lower part of the melting tank and is communicated with a spraying chamber which is horizontally arranged; a nozzle stretching into an atomizing chamber is arranged at the right end of the injecting chamber; a sieving mesh is arranged at the bottom of the atomizing chamber, and a dust collector is connected at the lower part of the sieving mesh; the indium powder manufacturing system is provided with a gas supplying chamber, wherein gas in the gas supplying chamber is conveyed to the injecting chamber through a compressor; gas mixed with the liquid indium in the injecting chamber is sprayed into the atomizing chamber through the nozzle; and the gas in the atomizing chamber flows into the dust collector, and then is exhausted through an exhaust fan. According to the indium powder manufacturing system, the gas-liquid mixture is injected into the atomizing chamber through the nozzle, so that the liquid indium can be uniformly atomized into relatively small powder indium particles, and the metal indium can prevent from being distilled by using a high-temperature resisting material; the indium powder manufacturing system not only can achieve uniform refining, has relatively high yield, but also has simple structure and relatively low cost of production.

Description

technical field [0001] The invention relates to a system for preparing indium powder. Background technique [0002] Fine indium powder is an important industrial raw material, mainly used in the preparation of TTO targets and electronic products, etc., and its application prospects are very broad. With the increase in the industrial demand for indium powder, the production equipment and systems of fine indium powder have been developed to a certain extent. At present, electrolysis and distillation are generally used to prepare fine indium powder. Due to the low output rate of indium powder with qualified particle size produced by electrolysis, it takes a lot of manual labor to grind the spongy precipitate of indium into powder, which not only has high production cost and low efficiency, but also hinders the industrial scale of indium powder The distillation method is to heat metal indium to above 2000°C, and condense the volatilized indium vapor to obtain indium powder.

Due to the low output rate of indium powder with qualified particle size produced by electrolysis, it takes a lot of manual labor to grind the spongy precipitate of indium into powder, which not only has high production cost and low efficiency, but also hinders the industrial scale of indium powder and the distillation method is to heat metal indium to above 2000°C, and condense the volatilized indium vapor to obtain indium powder. Although the particle size of the indium powder produced is uniform, the equipment used needs to be made of high-temperature-resistant materials, which is expensive
