Precious metal stirring and mixing device

Abstract

The invention belongs to the technical field of stirring equipment, and specifically discloses a precious metal stirring and mixing device, which includes a top cover, a bottom support plate, an outer cylinder, an inner cylinder, a first lifting power cylinder and a rotating part, and the bottom support plate is located under the top cover , the outer cylinder is fixedly connected to the lower surface of the top cover, the inner cylinder is placed on the upper surface of the bottom support plate, the outer cylinder is sleeved outside the inner cylinder, and a second gap is left between the inner cylinder and the outer cylinder. Mixing chamber; the vertical distance from the lower surface of the outer cylinder to the upper surface of the bottom support plate ≥ the vertical distance from the upper surface of the inner cylinder to the lower surface of the top cover; the inner cylinder is provided with a discharge material that can slide along the center line of the inner cylinder plate. The noble metal stirring and mixing device provided by the invention has a long service life and no dead angle of stirring.

Description

technical field [0001] The invention belongs to the technical field of stirring equipment, in particular to a noble metal stirring and mixing device. Background technique [0002] With the increasing shortage of mineral resources, precious metal resources (such as palladium, silver, and platinum) are becoming less and less, and industrial waste containing precious metal resources is discarded as garbage, which will cause water and soil environmental pollution. Therefore, precious metal resources in industrial waste Recycling is becoming more and more important. [0003] In the recovery process of precious metals, it is necessary to fully stir and mix the solid extracts containing precious metals, but it is difficult for the current stirring and mixing devices to ensure uniform stirring of the solid extracts. [0004] In order to solve the above problems, the Chinese invention patent application with the application publication number of CN108543466A discloses a noble metal ...

AI Technical Summary

Problems solved by technology

[0005] Although the above-mentioned patent application has carried out secondary stirring on the solid extraction material containing precious metals, the following problems still exist: (1) There is a dead angle of stirring that cannot be touched by the stirring paddle, which cannot ensure sufficient stirring of the precious metal; (2) The stirring paddle is in the horizontal The length in the direction is long, and the stirring blade is easily bent during the rotation process, resulting in a short life of the entire mixing device
