Feeding device for rare earth waste water processing

Abstract

The invention discloses a feeding device for rare earth waste water processing. The feeding device mainly comprises a waste water pumping main body, the waste water pumping main body is composed of ahopper, a conveying pipe, an intermediate tank, a communicating nozzle, a thermal evaporation concentration tank and an emptying nozzle, a discharging port of the hopper is in butt joint with a feeding port of the conveying pipe, and a discharging port of the conveying pipe is in butt joint with a feeding port of the intermediate tank; and a discharging opening in the bottom of the intermediate tank is in butt joint with the communicating nozzle. In the actual operation process, when materials are accumulated in the intermediate tank, double-tank circulation is achieved through a first communicating pipe and a second communicating pipe, in this way, excessive loads of the accumulated materials on the intermediate tank can be reduced, and meanwhile, the situation that the materials are solidified is avoided; and the situation that waste and defective materials are generated can be effectively avoided on the whole.

Description

Technical field [0001] The invention relates to the field of rare earth processing, in particular to a feeding device for processing rare earth wastewater. Background technique [0002] At present, the content of rare earth oxides in the rare earth ores mined in China and other countries in the world is only a few percent, or even lower. In order to meet the production requirements of smelting, the rare earth minerals and gangue minerals are extracted before smelting. Separate it from other useful minerals to increase the content of rare earth oxides and obtain rare earth concentrates that can meet the requirements of rare earth metallurgy. The extraction of rare earth ore generally uses flotation, and is often supplemented by a combination of gravity separation and magnetic separation. [0003] The current equipment for extracting rare earth from rare earth wastewater mostly adds an intermediate storage tank after the conveying pipe. When the temperature is low, the intermediate ...

Problems solved by technology

[0003] The current equipment for extracting rare earth from rare earth wastewater usually adds an intermediate storage tank behind the conveying pipe. When the temperature is low, the intermediate storage tank is used to store the heated material, thereby improving the extraction efficiency. For a long time, it is easy to appear that some materials cannot be heated and partially solidified.
