High-temperature hot-pressing pump pickling device for non-metal mine

Abstract

The invention relates to a non-metal mining high-temperature hot-pressing pump pickling device which comprises a tank body (1) and is characterized in that a heat exchange groove (2) and a heat preservation layer (3) are sequentially arranged on the outer side of the tank body (1) in a sleeved mode, a pump body I (4), a set of pump bodies II (5) and a pump body III (6) are arranged, and feeding pipes and discharging pipes of the pump body I (4), the pump bodies II (5) and the pump body III (6) are all communicated with the tank body (1). The feed pipes of the pump body I (4), the pump body II (5) and the pump body III (6) are communicated with branch pipes (8) through tee joints (7); and each branch pipe (8) is provided with a control valve (9) which is correspondingly matched with the branch pipe (8). The continuous scrubbing and leaching device is simple in structure and convenient to use, continuous scrubbing and leaching are conducted in the heating and pressurizing environment and in the turbulent flow state, the leaching efficiency is improved while large-scale production can be achieved, generated acid mist, steam and the like can be discharged in an organized mode and purified in a centralized mode, and the production efficiency is improved.

Description

Technical field: [0001] The invention relates to the field of processing non-metallic minerals, in particular to a high-temperature hot-pressure pump pickling device for non-metallic minerals. Background technique: [0002] At this stage, with the formulation of the national "dual carbon" strategic goal, the demand for high-quality non-metallic mineral products (such as quartz, feldspar, etc.) in the new energy photovoltaic industry has surged, which is in sharp contrast with the gradual scarcity of high-quality mineral resources at this stage. It is difficult for a large number of non-metallic minerals to meet the quality requirements of product raw materials by conventional physical beneficiation and flotation purification processes. These low-quality and difficult-to-select minerals Fe 2 O 3 The reason for the high content and difficult selection is usually that the surface or its micro-cracks are heavily impregnated by iron. By adding acid medium and high-temperature h...

AI Technical Summary

Problems solved by technology

Acid leaching equipment usually operates statically or semi-statically, and the pulp does not flow, resulting in low leaching efficiency and poor leaching effect

The pickling is carried out by mechanical agitation scrubbing, which improves the leaching efficiency and effect to a certain extent, but like pickling, there is the problem of mist and steam (such as acid mist and acid steam) with medium, resulting in harsh working and production environments. environmental hazards
