Device for extracting residual saline matters from industrial waste residues

Abstract

The invention belongs to the technical field of treatment of industrial waste residues and particularly relates to a device for extracting residual saline matters from the industrial waste residues. The device comprises a base, wherein a shell body is fixedly mounted at the top of the base, two crushing rollers are symmetrically and rotatably mounted in the shell body, one end of each crushing roller extends out of the shell body and is fixedly provided with a gear, a first motor is fixedly mounted at one side of the shell body, an output shaft of the first motor is fixedly connected with onegear, a screen supporting frame is rotatably mounted in the shell body, a screen is fixedly mounted on the screen supporting frame, a second motor is fixedly mounted in the shell body, a cam is fixedly mounted on an output shaft of the second motor and is in contact with the screen supporting frame, and a first spring is fixedly mounted in the shell body. The device is high in practicability and can be used for carrying out dissolving and filtering, and thus, the recovery cost is reduced; and meanwhile, the waste residues can be crushed, the dissolving is high in speed and is complete, and thus, the recovery rate is increased.

Description

technical field [0001] The invention relates to the technical field of industrial waste residue treatment, in particular to an industrial waste residue residual salt extraction device. Background technique [0002] Industrial waste refers to the toxic, flammable, corrosive, infectious, chemically reactive and other harmful solid wastes discharged in industrial production. It can be discharged after treatment. When the industrial waste residue is processed, the residual salt in the industrial waste residue can be extracted and recovered, so as to improve the industrial production efficiency and effectively utilize the resources. [0003] When extracting residual salt from industrial waste residue in the prior art, first, the industrial waste residue needs to be dissolved, mainly by acid solution, filtered after dissolution, neutralized by alkali solution, and finally recovered by crystallization. [0004] However, in the prior art, the dissolving is to directly place the ind...

Problems solved by technology

[0004] However, in the prior art, the dissolution is to directly place the industrial waste residue in the acid solution. Due to the large particles of the industrial waste residue, the dissolution rate is slow and the dissolution is incomplete, which reduces the recovery rate. At the same time, the dissolution and filtration are carried out separately, and multiple The completion of the equipment will increase the cost of recycling and reduce the efficiency of recycling
