Description

TECHNICAL FIELD

[0001] The utility model relates to tungsten smelting field, concretely relates to a convenient no ammonia tungsten smelting equipment of discharging. BACKGROUND

[0002] Tungsten is an important industrial metal, which is widely used in hard alloy, electronics and chemical industry and other fields. Green coordination no ammonia smelting technology emerges as the times require, which marks the major innovation of tungsten smelting process. This technology avoids the use of ammonia and other harmful substances to the environment, not only reduces the burden on the environment, but also improves the utilization efficiency of resources.

[0003] Under such background, the applicant develops a no ammonia tungsten smelting process. The process uses sulfuric acid to decompose scheelite to obtain a crude tungstic acid mixture (a mixture of tungstic acid and solid calcium sulfate in solid form), then uses green coordination process to replace tungstic acid from the crude tungstic acid mixture to obtain a crude tungstic acid solution, and then uses complex extraction to remove molybdenum to obtain pure tungstic acid solution, and finally obtains tungsten trioxide through precipitation, filtration, drying and calcination.

[0004] Compared with the existing process, the solid crude tungstic acid mixture obtained after acid leaching of the ore is relatively large in amount (solid calcium sulfate exists), and the particles are relatively large, so the traditional plate and frame filter pressing method can be replaced by screening to separate solid and liquid, so as to improve the efficiency and reduce the equipment area. Because screening will not completely separate the solid and liquid, the applicant applied for a utility model patent with the application number 2024231188995 and the name of a crude tungstic acid mixture uniform crushing equipment on December 17, 2024, which is used to dry and crush the crude tungstic acid mixture screened out. But the simple screening needs to discharge the material after acid leaching and then transport it to the screening equipment, which reduces the continuity of the production line and the efficiency is not ideal. Therefore, the applicant plans to develop a convenient discharging equipment that can screen the material at the same time of discharging, so as to improve the continuity of the process and improve the production efficiency.
