Rare earth waste pretreatment workshop capable of automatically feeding

Abstract

The invention provides a rare earth waste pretreatment workshop capable of automatically feeding. The workshop comprises a feeding system, a heating system, a cooling system, a dust collecting systemand a heat exchange recovery system, wherein the feeding system is used for feeding materials to the heating system, the heating system is used for conveying and heating rare earth oxide waste, the cooling system is connected with the heating system and used for conveying and cooling the heated and oxidized rare earth waste, the dust collecting system comprises a finished product bin, the dust collecting system is connected with a rear end of the cooling system and is used for grinding the cooled rare earth waste into rare earth dust and collecting the rare earth dust into the finished productbin, the heat exchange recovery system achieves graded cooling of the rare earth waste through air draft at a tail end of the heating system and air draft at a front end of the cooling system. The workshop is advantaged in that full-closed and full-automatic machining of the rare earth waste can be achieved, and rare earth dust collection in the machining process can be achieved.

Description

technical field [0001] The invention relates to the field of rare earth pretreatment equipment, in particular to a rare earth waste pretreatment workshop capable of automatic feeding. Background technique [0002] Before the extraction of rare earth waste, it is generally necessary to heat and oxidize the rare earth waste, and the rare earth waste after the oxidation heat treatment in the heating kiln needs to be further cooled to below 40 to 50 degrees before entering the subsequent pulverization process of rare earth waste pretreatment It is convenient for rare earth extraction after pretreatment. [0003] The traditional rare earth waste pretreatment process is pulverization and stirring of rare earth materials-heating oxidation-natural cooling-powdering. Specifically, the temperature of rare earth wastes is very high after heating and oxidation in the heating kiln, so after the rare earth wastes are poured out from the heating kiln, it needs to be naturally Cool down to...

Problems solved by technology

[0003] The traditional rare earth waste pretreatment process is pulverization and stirring of rare earth materials-heating oxidation-natural cooling-powdering. Specifically, the temperature of rare earth wastes is very high after heating and oxidation in the heating kiln, so after the rare earth wastes are poured out from the heating kiln, it needs to be naturally Cool down to a suitable temperature, and then manually transport the rare earth waste to the next process for processing. On the one hand, the overall pretreatment time is greatly increased due to natural cooling, and on the other hand, it is impossible to realize automatic mixing and automatic feeding of rare earth waste, which requires manpower. Transportation and turnover will increase labor costs, and rare earth dust will also be caused to fly during the process of pouring out and pouring rare earth waste in various processes, which not only wastes materials, but also pollutes the pretreatment workshop

[0004] In summary, the existing rare earth waste pretreatment workshop is completely unable to realize fully automated processing with automatic feeding, and cannot completely collect rare earth dust during processing
