Embodiment Construction

[0035] The present invention will be further described by means of embodiments below in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the described embodiments.

[0036] Such as Figure 1-3 As shown, the recovery device 10 for solid matter includes: a feeding device, a precipitation or crystallization reactor 40 , a filtration separation reactor 50 , a liquid collector 60 and a suction filtration pump 70 .

[0037] The feeding device is used to provide feed liquid and precipitant;

[0038] The precipitation or crystallization reactor 40 includes a first feed port, a feed liquid recovery port 45 and a first discharge port 46, and the first feed port communicates with the feed device. The precipitation or crystallization reactor 40 receives the feed liquid and the precipitating agent, and the feed liquid and the precipitant react in the precipitation or crystallization reactor 40 to form mother liquor and solid matter after...

Abstract

The invention discloses a recovering apparatus for solid matters. The recovering apparatus comprises a feeding device, which is used for providing feed liquid and a precipitating agent; a precipitation or crystallization reaction vessel, which receives the feed liquid and the precipitating agent and allows the feed liquid to react with the precipitating agent in the precipitation or crystallization reaction vessel to produce mother liquor and solid matters; and a filtering and separating reaction vessel, which receives the mother liquor and the solid matters, wherein the mother liquor and thesolid matters are separated from each other through pumping filtration in the filtering and separating reaction vessel, and the mother liquor is conveyed back to the precipitation or crystallization reaction vessel. The recovering apparatus is provided with a pumping filtration pump, so the desired solid matters (i.e., precipitated crystals) can be rapidly acquired, and the extracted mother liquoris returned to the precipitation or crystallization reaction vessel for reaction, which enables the utilization rate of the mother liquor to be increased.

Description

technical field [0001] The invention relates to a recovery device for solid matter. Background technique [0002] When there is a chemical reaction between solid and liquid or liquid and liquid, when the concentration of the reactant in the liquid phase exceeds its saturation concentration, it will be precipitated in the form of crystals. The production of crystals is to form very fine microcrystalline nuclei first, and then the nuclei grow into crystals of a certain shape. In the chemical industry and hydrometallurgical industry, precipitation and solid-liquid separation are key production steps. Most of the precipitation reactions are carried out in separate equipment, and the crystals are obtained by the clarification method, which has a large workload, low efficiency, and low utilization of the mother liquor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a solid substance recovery device with high efficie...
