Reaction chamber for producing aluminum oxide

Abstract

The invention discloses a reaction chamber for alumina production, which comprises a reaction chamber outside the reaction chamber and a precipitation cylinder. The upper end of the reaction chamber outside the reaction chamber is provided with an equipment compartment, and a first drive motor is installed inside the equipment compartment. The front end of a drive motor is connected with a reducer, and the front end of the reducer is equipped with a connecting shaft, the outside of the connecting shaft is connected with a stirring blade, and the outer surface of the stirring blade is provided with a fan hole, and the inside of the fan hole is A rotating shaft is connected, and fan blades are installed on the outer surface of the rotating shaft, a bearing is arranged on the inner bottom surface of the precipitation cylinder, and a placement plate is installed on the lower end of the precipitation cylinder. The reaction chamber for alumina production is designed with sound-absorbing boards, reducers, stirring blades, bearings, refrigerators, gear plates, rollers, damping plates and pneumatic devices, which can absorb noise, increase the speed of precipitation, and reduce The cooling time can prevent the balance in the precipitation cylinder from being broken, causing the aluminum hydroxide crystals to dissolve into the solution again.

Description

technical field [0001] The invention relates to the technical field related to alumina production, in particular to a reaction chamber for alumina production. Background technique [0002] Alumina is a compound with high melting point and high boiling point. It has high application value. my country has become the largest alumina producer in the world. In the production of alumina, the generally used method is the Bayer method. The principle is to use The caustic soda solution is heated to dissolve the alumina in the bauxite to obtain a sodium aluminate solution. After the solution is separated from the residue, the temperature is lowered, and aluminum hydroxide is added as a seed crystal. After a long period of stirring, the sodium aluminate decomposes and precipitates aluminum hydroxide crystals. In order to adapt to this precipitation reaction, it is necessary to research and invent a production reaction for alumina The reaction chamber used for alumina production reactio...
