Raw material dewatering device for preparing rubber and plastic filler by taking lithium slag as raw materials

Abstract

The invention belongs to the technical field of lithium slag dewatering, and particularly relates to a raw material dewatering device for preparing rubber and plastic filler by taking lithium slag asraw materials. The raw material dewatering device for preparing the rubber and plastic filler by taking the lithium slag as the raw materials comprises a storage tank, a conveying mechanism and a dewatering bin, wherein the left lower end of the conveying mechanism is positioned in the storage tank, the right upper end of the conveying mechanism is positioned on the upper side of the dewatering bin, the conveying mechanism conveys materials in the storage tank into the dewatering bin, the lower surface of the dewatering bin is provided with a driving motor through a motor seat, and the bottomend of an output shaft of the driving motor is connected with a driving gear. Materials can be continuously conveyed through the arrangement of the conveying mechanism, and the dewatered materials canbe directly discharged through a collection cover and a discharge pipe, so that the dewatering operation efficiency can be improved, and the continuity is good. Through an operation mode of matchinga heating device with centrifugal dehydration, the dehydration efficiency can be improved, and the drying effect is achieved. The lithium slag and water are conveniently separated and discharged through the functions of separate output of the discharge pipe and a liquid discharge port.

Description

technical field [0001] The invention relates to the technical field of lithium slag dehydration, in particular to a raw material dehydration device for preparing rubber and plastic fillers using lithium slag as a 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 has imposed a heavy environmental...
