Convenient-to-clean reaction kettle for zinc sulfate production

Abstract

The invention discloses a convenient-to-clean reaction kettle for zinc sulfate production. The reaction kettle comprises a kettle body and a rack for fixing the kettle body, wherein the kettle body isfixed on a supporting plate at the upper end of the rack; the outer side of the bottom end of the kettle body is fixedly connected with a cross beam between two groups of support legs of the rack through fixing rods; a feeding pipe, an adding pipe and a rotating shaft are mounted at the top end of the kettle body; the bottom end of the kettle body is arc-shaped; a discharge port is formed in themiddle of the kettle body; a discharge pipe is fixedly mounted on the discharge port; the rotating shaft is fixedly inserted into the middle position of the kettle body through a bearing; the bottom end of the rotating shaft is connected with a bottom wiping plate through an electric push rod; stirring fan blades and nozzles are symmetrically mounted at the lower end of the rotating shaft, and cleaning assemblies are arranged at parts, on both sides of the rotating shaft, of the interior of the kettle body. According to the convenient-to-clean reaction kettle for zinc sulfate production, sediments attached to the inner wall are scraped and cleaned, and in cooperation with the nozzles mounted on the rotating shaft, when the kettle body is cleaned, scraping and water spraying can be conducted at the same time, and the cleaning effect of the reaction kettle is improved.

Description

technical field [0001] The invention belongs to the technical field of zinc sulfate production equipment, and in particular relates to an easy-to-clean reaction kettle for zinc sulfate production. Background technique [0002] Zinc sulfate, also known as alumite or zinc alumite, is a colorless or white orthorhombic crystal or powder at room temperature. It is astringent and easily soluble in water. The aqueous solution is acidic, slightly soluble in ethanol and glycerin. Pure zinc sulfate does not turn yellow when stored in the air for a long time, and loses water in dry air to form a white powder. During the production of zinc sulfate, the filtrate needs to be removed from impurities, and the filtrate needs to be sent to a replacement reactor and heated to 80°C. Add zinc powder to replace heavy metal impurities such as copper and lead, and then filter out the replacement hydraulic pressure to replace heavy metals such as copper and lead. [0003] However, when zinc sulfate...

Problems solved by technology

[0003] However, when zinc sulfate is reacted in the reactor during the preparation process, in order to improve the purity of zinc sulfate, it is generally necessary to add too much zinc powder and carry out a chemical reaction to replace all heavy metals such as copper and lead in the filtrate, as shown in the authorization announcement No. CN209138633U shows a kind of waste slag recycling device for zinc sulfate production. In the process of preparing zinc sulfate, although a device for removing and cleaning impurities is added, in this application, the inner wall of the reactor is not cleaned. Due to the mechanism, after the reaction is completed, some precipitated precipitates are attached to the inner wall. At the same time, when cleaning the kettle body, it will cause inconvenience, affect the cleaning efficiency, and increase the consumption of water resources. Conducive to cost reduction
