System for automatically charging a dry powder material

Abstract

The invention relates to a system for automatically charging a dry powder material. The system for automatically charging the dry powder material comprises a raw material charging hopper, an electronic belt scale, a storage hopper, a scraper conveyer, a pulping groove and a screw conveyer, wherein the charging hopper is arranged at the lower end of the scraper conveyer; the storage hopper is arranged at the upper end of the scraper conveyer; an electrohydraulic gate is arranged at the lower end of the storage hopper; the lower end of the electrohydraulic gate is connected with a star feeding machine; the electronic belt scale is arranged at the lower end of the star feeding machine; the screw conveyer is arranged at the lower end of the electronic belt scale; the raw material pulping groove is arranged at the lower end of the screw conveyer; a stirring device is arranged at the upper end of the pulping groove; and a driving device of the scraper conveyer is arranged at the upper end of the scraper conveyer. The dry power material can be added precisely, quantitatively and continuously by an electronic belt scale automatically charging technique, so that Fe<3+> and Fe<2+> of the system can be stably controlled, vitriol precipitate supernatant is clear and the solid content is low. Environmental pollution caused by manganese powder and ammonium bicarbonate and damage to a human body are eliminated, so the system has high economic value and high industrial popularization value.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical batching and feeding in the zinc hydrometallurgy industry, in particular to an automatic feeding system for dry powder materials. Background technique [0002] With the development of the world economy, the country has higher and higher requirements for energy conservation and emission reduction. Enterprise energy conservation and emission reduction has become an important and urgent task for my country's current economic and social development. Energy conservation and emission reduction in the hydrometallurgical industry is also imminent. . The addition of zinc hydrometallurgy reagents is an important link in the high-temperature and high-acid jarosite iron removal process. It is related to the accuracy of the process technical index control, the quality of the supernatant of the supernatant, the rate of the supernatant and the quality of the product. important part of eligibility. At pre...
