Horizontal pressure leaching reaction kettle

Abstract

The invention discloses a horizontal pressure leaching reaction kettle. The reaction kettle comprises a kettle body and a plurality of shelves, wherein the plurality of shelves are connected with the inner wall of the kettle body, and the kettle body is separated into a plurality of reaction chambers by adjacent shelves at preset intervals; the top of each shelf is provided with a concave part which ensures that a reaction material in one upstream reaction chamber overflows to the adjacent downstream reaction chamber; and one side, adjacent to the adjacent downstream reaction chamber, of each shelf is provided with a guide cylinder which carries reaction materials which overflow from the concave part; and the upper edge of each guide cylinder is protruded from the lower edge of the concave part along the vertical direction. According to the horizontal pressure leaching reaction kettle disclosed by the embodiment of the invention, the reaction materials in each reaction chamber can be uniformly mixed, so that the leaching rate of ore pulp materials is improved, the production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of metal smelting, in particular to a horizontal pressurized leaching reactor for hydrometallurgy. Background technique [0002] The horizontal pressurized leaching reaction kettle used in the non-ferrous smelting industry uses partitions to divide the inside of the kettle into four to seven chambers. There are generally four to five rooms in China, and the height of the partitions is set in steps from high to low. After pulping, the leaching material is pumped into the first chamber of the reaction kettle with a pressure pump. After the volume of the pulp is close to the position of the partition of the reaction kettle, it overflows to the next chamber under the action of the agitator to realize the transfer of materials. During the production process, the leaching material is prone to enter the next chamber without sufficient reaction, resulting in low leaching rate of metal materials, high content of ins...

AI Technical Summary

Problems solved by technology

During the production process, the leached material is prone to incomplete reaction and enters the next chamber, resulting in low leaching rate of metal materials, high content of insoluble metals in slag, and low metal recovery rate.
