Abstract

The invention provides precious metal recycling equipment and belongs to the technical field of heavy metal processing equipment. A dissolving cavity is provided with a material inlet and a liquid inlet. A motor is connected with a spiral blade through a rotating shaft, the upper end of the dissolving cavity is provided with an adsorption layer, the inner bottom of the dissolving cavity is provided with an upper pusher, the upper pusher is connected with an upper scrapping plate, the dissolving cavity is externally provided with a hydraulic pump, and the dissolving cavity is internally provided with a push plate. The hydraulic pump is connected with the push plate through a hydraulic rod, the lower end of the dissolving cavity is provided with a filtering cavity, the dissolving cavity is connected with the filtering cavity through a channel, and the filtering cavity is internally provided with a first-grade filtering mesh and a second filtering mesh. The first-grade filtering mesh is located at the upper end of the second-grade filtering mesh, and the hole diameter of the first-grade filtering mesh is larger than that of the second-grade filtering mesh. One side of the filtering cavity is provided with a slag discharging opening, and the lower end of the filtering cavity is provided with a material outlet. The upper scraping plate and the push plate are oppositely arranged. Harmful gases are adsorbed by the adsorption layer, the dissolving speed of heavy metal is increased through the spiral blade, the upper scraping plate and the push plate, filtering is performed throughthe first-grade filtering mesh and the second-grade filtering mesh, and the recycling effect of the heavy metal is improved.

Description

Technical field [0001] The invention belongs to the technical field of precious metal processing equipment, and relates to a precious metal recovery equipment. Background technique [0002] The extraction, separation, refining and preparation of precious metals all need to be dissolved, so the reaction vessel for the dissolution of precious metals is particularly important. Easily soluble precious metals are usually leached from waste by hydrometallurgical technology. The main methods are 1. A regia dissolution: This is a classic method for precious metal scrap. Because of its reliable technology, high yield and short cycle, it is widely used in bulk precious metal scrap and high Content of the dissolution of precious metal waste; 2. Sulfuric acid or nitric acid dissolution: Sulfuric acid or nitric acid can react with palladium to produce soluble sulfate and nitrate; 3. Aqueous chlorination dissolution: Aqueous chlorination method refers to the medium of water and HCl solution C...
