A high-efficiency mixing device for rare earth production

Abstract

The invention discloses a high-efficiency mixing device for rare earth production, comprising a mixing tank, a first driving device is arranged at the upper end of the mixing tank, a second driving device is arranged at the lower end, and a first rotating shaft is vertically arranged in the mixing tank , the second rotating shaft, the feeding pipe and the dispersing cover, and the second rotating shaft is provided with a helical blade; the second driving device, the second rotating shaft, the feeding pipe and the helical blade constitute a screw feeding mechanism, which transports the materials at the bottom of the mixing tank to the top of the feeding pipe, and then scattered on the dispersing hood. The first driving device drives the dispersing hood to rotate through the first rotating shaft, so that the materials scattered on the dispersing hood are dispersed and then fall down, and then the mixing tank is moved by the screw feeding mechanism. The material at the bottom is transported to the top of the feeding tube, and the material is mixed in this way. The mixing method of the invention not only realizes the cyclic mixing of the materials, but also continuously disperses them in the mixing process, so that the rare earth production materials can be uniformly mixed quickly, the time required for uniform mixing is short, and the production efficiency is high.

Description

technical field [0001] The invention relates to the field of stirring devices, in particular to a high-efficiency mixing device for rare earth production. Background technique [0002] China has relatively rich rare earth resources, and China's rare earth reserves account for about 23% of the world's total reserves. Because of their unique physical and chemical properties, rare earths are widely used in new energy, new materials, energy conservation and environmental protection, aerospace, electronic information and other fields, and are indispensable and important elements in modern industry. [0003] When using rare earth as raw material for production, it is necessary to use a mixer to mix the rare earth raw material and other raw materials evenly before proceeding to the next step of production. The traditional mixing machine mixes various raw materials put into the mixing tank by stirring and mixing. For rare earth, its density is relatively high and its dispersion is ...
