Problems solved by technology

However, the transmission device is inside the hopper, and the transmission device is easy to rub against the powdered rare earth oxide during feeding, causing the wear of the feeding device, resulting in a reduction in the service life of the feeding device
In addition, rare earth oxides have poor fluidity and are prone to clogging, especially the use of feeding nozzles is more likely to cause clogging

Abstract

The invention discloses a blanking device for a rare-earth electrolysis bath, and the rare-earth electrolysis bath. The blanking device comprises a hollow stock bin; the stock bin is provided with a blanking opening; the blanking device also comprises a helical discharger and a driving mechanism; the helical discharger comprises a shell comprising a cylindrical cavity; the shell is provided with afeeding opening and a discharging opening, wherein the feeding opening communicates with the blanking opening; the discharging opening is used for a material to flow into an electrolysis bath body; aconveying threaded column used for conveying the material inside the shell to the position of the discharging opening is arranged inside the cavity of the shell; and the conveying threaded column hastransmission connection with the driving mechanism. The blanking device for the rare-earth electrolysis bath, disclosed by the invention, has a quantitative blanking function, can effectively preventprecipitation in the bath due to excess blanking and a lack-of-material state of the electrolysis bath due to insufficient blanking, is hard to block, simple in device and convenient to install and maintain, and lowers the labor intensity of a worker.

Description

technical field [0001] The invention relates to a rare earth electrolytic tank feeding device and a rare earth electrolytic tank, belonging to the field of metallurgical equipment. Background technique [0002] At present, molten salt electrolysis is the main method for producing rare earths. The technical equipment of the rare earth electrolysis industry is relatively backward, resulting in low production efficiency, poor stability of production process control, strong dependence on manual experience and serious environmental pollution. In particular, rare earth electrolytic blanking relies entirely on manual experience and manual feeding, which leads to poor feeding control accuracy and high labor intensity, resulting in low current efficiency and energy utilization, which greatly limits the development of large-scale rare earth electrolytic cells. The current efficiency of the electrolyzer is only about 70%, the energy utilization rate is about 15%, and the energy saving ...
