A kind of aluminum oxide refining industrial solid waste recycling processing equipment

Abstract

The invention relates to recycling and processing equipment of industrial solid wastes in alumina refining. The recycling and processing equipment comprises a bottom plate, a mixing device and a waterquenching device, wherein the mixing device is arranged at an upper left end of the bottom plate, and the water quenching device is arranged at an upper right end of the bottom plate. The recycling and processing equipment has the advantages that the difficulties that the existing red-mud wastes are generally accumulated for storage, after long-time accumulation, the land and water sources are polluted, the use of the land and water sources is affected, the recycling rate of the red-mud wastes is low, when the red mud is used for manufacturing microcrystal glass, the production efficiency islow, the labor intensity is large, the red mud can not be uniformly mixed with added materials, the operation is complex, the labor intensity is large and the working efficiency is low and the like can be solved; the functions of automatic mixing, melting and water quenching for the red-mud wastes can be realized, the hazard of red-mud accumulation to the environment can be avoided, the recyclingrate of the red mud can be increased, the red mud can be uniformly mixed with the added materials, the manual operation can be avoided, the operation is simple, the labor intensity is low and the working efficiency is high and the like.

Description

technical field [0001] The invention relates to the field of red mud treatment equipment, in particular to a recovery and utilization processing equipment for alumina refining industrial solid waste. Background technique [0002] Red mud, also known as red mud, is an industrial solid waste discharged from bauxite after refining alumina. It generally contains a large amount of iron oxide and has a similar appearance to red soil. Red mud is a polluting waste discharged from the aluminum industry when alumina is extracted. Generally, for every ton of alumina produced on average, 1.0 to 2.0 tons of red mud are incidentally produced. As the fourth largest producer of alumina in the world, China discharges millions of tons of red mud every year. If the red mud is not recycled, it will cause harm to the environment. [0003] Existing red mud waste is usually stored in piles. Long-term stacking will pollute the land and water sources and affect its use. Moreover, the recycling rate...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a recycling processing equipment for alumina refining industrial solid waste. The present invention can solve the problem that the existing red mud waste is usually piled up and stored, and long-term stacking will pollute the land and water sources and affect the use. , and the recycling rate of red mud waste is low, the production efficiency is low and the labor intensity is high when red mud is made into glass-ceramic, the red mud cannot be mixed evenly with the added materials, the operation is complicated, the labor intensity is high, and the work efficiency is low. Realize the functions of automatic mixing, melting and water quenching of red mud waste, which can avoid the harm caused by red mud stacking to the environment, improve the recycling rate of red mud, and can evenly mix red mud with additive materials, avoid manual operation, and operate Simple, low labor intensity and high work efficiency
