AI Technical Summary
During the production of aluminum fluoride, the feed hood at the feed end of the rotary drying kiln is prone to blockage due to the settling of powder and moisture in the high-temperature exhaust gas, which affects the smooth flow of materials.
A 60º angled loosening plate is installed at the front end of the rotary kiln and rotates synchronously with the kiln. The loosening plate agitates the deposited powder and guides the material to the feeding device through a 45º angled guide plate. The feeding device rotates synchronously with the kiln to ensure that the material is continuously fed into the kiln.
It effectively prevents blockage of the exhaust gas conveying channel of the feed hood, ensures the continuity and smooth flow of materials, and improves production efficiency.

Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of aluminium fluoride production, specifically is anti -blocking rotary feeding device. BACKGROUND
[0002] Aluminium fluoride is used as a flux in the production of electrolytic aluminium to reduce the melting point of aluminium oxide in the electrolytic process and enhance the conductivity of the electrolyte, thereby improving the production efficiency and quality of aluminium. Aluminium fluoride paste is made of fluorosilicic acid and aluminium hydroxide.
[0003] At the feeding end of the rotary drying kiln, the feeding cover plays a role in connecting and transitioning between the moving equipment (rotary drying kiln) and the static equipment (tail gas pipeline, conveying screw), and in conveying high-temperature tail gas. The aluminium fluoride paste is conveyed to the rotary drying kiln by the conveying screw and dried by high-temperature flue gas. The flow direction of the paste is opposite to that of the high-temperature tail gas. Since the high-temperature flue gas (tail gas) has a certain flow rate and directly contacts the paste, a large amount of aluminium fluoride powder is contained in the tail gas. When the powder flows upward after passing through the feeding device, it rapidly settles in the feeding cover due to gravity, and a large amount of "water vapor" is contained in the tail gas, causing the settled powder to harden and block the feeding cover.
[0004] Therefore, the anti-blocking rotary feeding device is provided. CONTENT OF THE UTILITY MODEL
