Raw material magnetic separation device for preparing rubber-plastic filler by taking lithium slag as raw material

Abstract

The invention discloses the technical field of green resource utilization of industrial solid wastes, particularly to a raw material magnetic separation device for preparing a rubber-plastic filler bytaking lithium slag as a raw material. The device comprises a semicircular outer cylinder body, an inner cavity of the semicircular outer cylinder is connected with a magnetic separation roller through a rotating shaft; the magnetic separation roller is driven by a driving mechanism to rotate, and a support is arranged at the bottom of the semicircular outer cylinder; through the cooperation of asmashing bin, a smashing roller, a driving motor and a belt wheel mechanism, added lithium slag materials can be smashed in a grinding mode, so that magnetic particles in the materials are conveniently separated, and the magnetic separation efficiency is improved. Under the matching action of a limiting stop block, a scraper body and a supporting spring, a scraper body is elastically pressed on the outer wall of the magnetic separation roller, so that the scraper body is stably in contact with the outer wall of the magnetic separation roller, and materials on the outer wall of the magnetic separation roller are conveniently scraped off; and through the arrangement of a loosening brush roller, magnetic particles on the outer wall of the magnetic separation roller can be loosened and conveniently scraped off.

Description

technical field [0001] The invention relates to the technical field of green resource utilization of industrial solid waste, in particular to a raw material magnetic separation device for preparing rubber and plastic fillers with lithium slag as raw material. Background technique [0002] Lithium slag is an industrial waste produced during the production of lithium carbonate by the spodumene sulfuric acid method. For every 1 ton of lithium carbonate produced, 8-10 tons of lithium slag will be discharged. In recent years, with the development of the new energy industry, the market demand for lithium carbonate has grown rapidly. According to statistics, the total domestic output of lithium salts in 2018 was 250,000 tons, and the annual discharge of lithium slag will reach 2.5 million tons. In addition to the accumulation over the years, the domestic lithium slag stockpile can reach tens of millions of tons, which brings great benefits to local governments and enterprises. It ...
