Leaching kettle

Abstract

The invention discloses a leaching kettle which comprises a kettle body and a plurality of partition walls, wherein a leaching cavity is formed in the kettle body; the kettle body comprises a metal housing and a brick layer arranged on an inner wall of the metal housing; the partition walls are arranged in the leaching cavity to divide the leaching cavity into a plurality of chambers; the top of each partition wall is spaced from a top wall of the leaching cavity to form a communicating channel for communicating the chambers with one another; the partition wall comprises a brick table and a metal bin partition board; the brick table is arranged on an inner wall of the kettle body and circumferentially extends along the kettle body; the metal bin partition board is mounted on the brick table. The leaching kettle disclosed by the embodiment of the invention has the advantages of high stability of the partition walls, long service life, simplicity for mounting and maintenance and small occupied space of the partition walls in the kettle.

Description

technical field [0001] The invention relates to the technical field of hydrometallurgy, in particular to a leaching kettle. Background technique [0002] The leaching kettle is a commonly used equipment in hydrometallurgy. In related technologies, in order to prevent corrosion of the metal shell by the medium, reduce the use of precious metals, and reduce investment and construction costs, bricks are usually lined on the inner wall of the kettle shell to achieve metal leaching. Taking the horizontal kettle as an example, the interior of the kettle is divided into several compartments by the partition wall, and the slurry passes through each partition wall in turn from the first compartment, and is discharged out of the kettle from the last compartment. [0003] The partition wall in the related art is built with corrosion-resistant bricks, in order to ensure the stability of the partition wall, the thickness of the partition wall reaches 300-350mm thick, and the accumulatio...

AI Technical Summary

Problems solved by technology

[0003] The partition wall in the related art is built with corrosion-resistant bricks, in order to ensure the stability of the partition wall, the thickness of the partition wall reaches 300-350mm thick, and the accumulation of multiple partition walls adds up to occupy the effective volume in the kettle, and Since the thermal expansion of the brick partition wall is restricted by the brick lining of the metal shell, it is easy to cause damage such as brick arching on the top of the partition wall or cracking of the wall after a period of operation, which not only affects normal use, but also has a large maintenance workload. Moreover, the replacement and maintenance workload is large and the cost is high, so there is a need for improvement
