AI Technical Summary

Technical Problem

In the existing indium oxide production process, the raw materials do not come into sufficient contact with the acid solution, resulting in low leaching efficiency, and large particles of raw materials affect the overall effect.

Method used

The reaction vessel is made of titanium alloy and is equipped with a screening plate, crushing spikes, extrusion blocks and sealing plate. The raw materials are refined through collision, crushing and extrusion, and the sealing plate enables intermittent feeding to ensure that the raw materials are in full contact with the acid solution.

Benefits of technology

It improves the leaching effect of indium oxide, ensures that the raw material is in full contact with the acid solution, improves leaching efficiency and quality, and reduces maintenance costs.

Abstract

The utility model discloses an acid-soluble leakproof tank for indium oxide production. The acid-soluble leakproof tank comprises a titanium alloy reaction tank and supporting legs, by adopting the collision thorns, the crushing thorns, the extrusion block and the sealing disc, raw materials and acid liquor can be respectively added in the indium oxide production leaching stage, and at the moment, the raw materials can be crushed for multiple times through the collision thorns and the crushing thorns, so that the granularity of the raw materials is reduced; meanwhile, small particles can be ground and further refined through cooperation of an extrusion block and crushing thorns, so that the raw materials can be in more sufficient contact with acid liquor subsequently, the overall leaching effect is improved, then the particles fall into a discharging hopper through sieve holes, and at the moment, the sealing disc is in intermittent contact with the discharging hopper, so that the leaching efficiency is improved. The device is simple in structure and convenient to operate, small-amount and multiple-time discharging operation of raw materials can be achieved, large-batch introduction of the raw materials is avoided, the raw materials can make full contact with acid liquor, the overall use quality is improved, and the device has the advantages of being good in leaching effect, capable of achieving material smashing and intermittent feeding.
