Embodiment Construction

[0030] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, a heat conduction closed continuous scrubbing and leaching equipment provided by the present invention includes a barrel-shaped leaching tank 1 with a regular octagonal structure and an upper end opening. The leaching tank 1 is made of stainless steel and is lined with polytetrafluoroethylene. Made, the leaching tank 1 rotates with a stirring shaft 2, and the stirring shaft 2 in the leaching tank 1 is sequentially connected to a section of spiral impeller 18, a pair of movable impellers 3 and another section of spiral impeller 18 from top to bottom, and the stirring shaft 2. One end protruding from the leaching tank 1 is connected with the externally fixed driving motor 4 in rotation.

[0031] A heat-conducting medium storage tank 6 with an insulating layer 5 is provided outside the leaching tank 1. The heat-conducting medium storage tank 6 is a cylindrical structure larger in size than the leaching tank...

Abstract

The invention relates to heat-conducting closed continuous scrubbing-leaching equipment. The heat-conducting closed continuous scrubbing-leaching equipment comprises a leaching tank (1) and a stirring shaft (2), wherein the stirring shaft (2) is connected with a drive motor (4); a heat-conducting medium storage tank (6) is formed at the outer side of the leaching tank; cover plates (7) for sealing the equipment are arranged on the upper parts of the leaching tank and the heat-conducting medium storage tank; a feeding hole (9) and a tail gas treatment and medium replenishment device (11) are arranged on the upper part of each cover plate; a discharge tube (10) is arranged at one side of the leaching tank; heating resistance wires (8) are arranged on the outer sidewall of the leaching tank; a temperature sensor (22) is connected to the inner wall of the leaching tank; an automatic PLC (23) is arranged on the outer wall of the heat-conducting medium storage tank (6); the temperature sensor (22) and the heating resistance wires (8) are in matching connection with the PLC (23). The heat-conducting closed continuous scrubbing-leaching equipment disclosed by the invention has the advantages that a scrubbing-leaching effect is enhanced, medium cyclic utilization is realized to the greatest extent, environment is purified, and environmental protection treatment pressure is alleviated.

Description

technical field [0001] The invention relates to mineral processing and purification equipment, in particular to a heat conduction closed continuous scrubbing and leaching equipment in the field of non-metallic mineral processing. Background technique [0002] With the increasing demand for non-metallic mineral products such as quartz sand in modern industry, there are fewer and fewer high-quality mineral deposits. Instead, some non-metallic mineral particles such as quartz sand or their micro-cracks are covered with iron minerals or Other impurity minerals are seriously impregnated, and it is difficult to meet the quality requirements of product raw materials by using conventional physical purification processes, which are poor and difficult to select minerals. Such minerals are often difficult to achieve the purpose of separation through physical process treatment or conventional scrubbing, and often require more stringent scrubbing conditions or deep purification processes...
