Abstract

The invention discloses a drying device for alumina production and processing, which comprises a vertical cylindrical shell and a horizontal cylindrical shell whose bottom end is fixed and connected, and the center of the vertical cylindrical shell is arranged There is a central fixed installation column, and the outer sleeve of the central fixed installation column is provided with a centrifugal separation and dehydration rotating sleeve. The centrifugal separation and dehydration rotating sleeve is abutted with an upper opening accommodating cavity plate, and the top opening of the upper opening accommodating cavity plate is screwed and connected with a protective cover. The upper screw cap is sealed, and the bottom end of the upper opening accommodation cavity is fixedly connected with a vertical rotating cylinder with two-way openings. In the present invention, the telescopic rod-type opening and closing heating mechanism is adopted to realize the drying and air-drying of the straight inner communication groove and the horizontal inner communication groove, and the centrifugal dehydration drying mechanism is adopted to realize the centrifugal effect during the rotation process to be thrown out to increase oxidation The drying and dehydration effect of aluminum adopts the centrifugal locking airway structure, which is convenient for the external airflow to be charged and used dryly, and at the same time, it is convenient to shake out the moisture for dry use.

Description

technical field [0001] The invention relates to the technical field of alumina drying equipment, in particular to a drying device for alumina production and processing. Background technique [0002] Alumina is an inorganic substance with the chemical formula Al 2 o 3 , is a high-hardness compound with a melting point of 2054°C and a boiling point of 2980°C. It is an ionic crystal that can be ionized at high temperatures and is often used in the manufacture of refractory materials; industrial alumina is made of bauxite (Al 2 o 3 ·3H 2 O) and diaspore. For alumina with high purity requirements, it is generally prepared by chemical methods. There are many isomorphous crystals of alumina. There are more than 10 known types, and there are mainly three crystal forms, namely α- Al 2 o 3 , β-Al 2 o 3 , γ-Al 2 o 3 , in which the structure is different and the properties are different, and it is almost completely transformed into α-Al at a high temperature above 1300 °C 2 o...
