Solid-liquid separation device for hydrometallurgy

Abstract

The invention discloses a solid-liquid separation device for hydrometallurgy. The solid-liquid separation device for hydrometallurgy comprises a primary filter box, a secondary filter box, a fractionation box and a condensation box which all sequentially communicate. The fractionation box is connected with an electrodeposition system. The interior of the primary filter box is divided into a dissolution chamber and a primary leaching chamber through a rigid mesh sieve and a filter net. The second filter box is internally provided with a suction filter net and a retarding plate. The second filter box is provided with a first vacuum pump. The fractionation box is provided with a second vacuum pump and a heating coil, and the fractionation box communicates with the condensation box through a third communicating pipe. The solid-liquid separation device for hydrometallurgy is high in separation speed, good in separation effect, capable of recovering a great number of recyclable matter, in the whole working process, conveying is carried out through pressure difference generated between two adjacent containers by the vacuum pump, the operational use time is long, and the part maintaining period is short.

Description

technical field [0001] The invention belongs to the technical field of hydrometallurgy equipment, and in particular relates to a solid-liquid separation device for hydrometallurgy. Background technique [0002] Hydrometallurgy is the process of dissolving metal minerals into alkaline, acidic aqueous solutions or organic solvents, and then extracting metals and their compounds through extraction, separation of impurities and extraction. This production process will produce a large amount of solid residues and The liquid substance, the solid residue is mainly raw ore or the recyclate containing a large amount of extractable metal is the dissolved part, the liquid substance is mainly the extract solution with a large amount of metal element or compound dissolved, and the key step in hydrometallurgy is to The solid residue is separated from the liquid substance, and then the liquid substance is processed to obtain the product. Whether the solid residue can be well separated from...

Problems solved by technology

[0003] In the prior art, most of the large-particle impurities are removed by natural precipitation, and most of the small-particle impurities are removed by filtration. Although this method is simple to operate, it will greatly increase the workload and workload of an extraction process. time, the overall effect of solid-liquid separation is not good, and pumps are needed in the transmission process of liquid substances. Due to the large amount of solid impurities in the previous process, it will cause greater damage or even damage to the pump, which is not conducive to the normal operation of the process. Carry out, in order to solve this problem, the present invention provides the following technical solutions
