Abstract

The invention relates to leaching equipment which adopts the technical scheme: the upper end of an upper cone (4) is fixedly connected with a cover plate (2), and a feeding hole (1) is arranged in the center of the cover plate (2); an observation hole (5) is arranged at the upper part of a shell of the upper cone (4), the shell of the upper cone (4) is provided with a circulating tube (6), the circulating tube (6) is communicated with an inner cavity of the upper cone (4), and a pipeline of the circulating tube (6) is connected with a water pump (7); and a steam inlet (9) is arranged on a shell of a lower cone (8), and a discharge hole (12) is fixedly installed at the conical top part of a bottom cone (10). The shells of the equipment are both made of high temperature resistance glass fiber reinforced plastics, each inner wall is coated with acid resistance coatings, bolt connection is respectively used between the cover plate (2) and the upper cone (4), between the upper cone (4) and the lower cone (8), and between the lower cone (8) and the bottom cone (10), and a sealing ring is respectively padded at each connecting part. The invention has the advantages of simple structure, high leaching efficiency and long service life and can satisfy the requirements of temperature resistance and acid resistance.

Description

Technical field [0001] The invention belongs to the technical field of hydrometallurgy. Specifically relates to a leaching equipment. Background technique [0002] Leaching is the process of selectively leaching a certain component or some components in the solid material with an appropriate leaching agent to form a solution containing the metal to be extracted, and thereby initially separating it from other insoluble components. Currently commonly used leaching equipment mainly includes: [0003] (1) Gas agitation type leaching tank: The compressed air of the cavitation machine is used to supply air to the inflatable stirring device, and the compressed air entering the inflatable stirring device creates a stirring effect on the slurry. The operability of the equipment is poor, the stirring is insufficient, and the leaching efficiency is not high (Wang Chengzhao, Sun Weidong, Li Wenyu, etc. The application of the new aerated stirred leaching tank in the cyanidation process. Minin...
