Abstract
Description
Technical Field
[0001] This utility model relates to the field of secondary aluminum ash technology, specifically to an explosion-proof hydrolysis device for secondary aluminum ash. Background Technology
[0002] Aluminum ash is a byproduct of the electrolytic aluminum industry, and it is divided into primary aluminum ash and secondary aluminum ash. Primary aluminum ash is the ash residue periodically removed during the smelting and casting process in the aluminum industry. After cooling, the ash residue is finely ground and sieved to separate aluminum particles. The resulting fine ash is secondary aluminum ash. In addition to aluminum oxide, secondary aluminum ash also contains toxic and harmful substances such as aluminum nitride and fluorides. According to the "National Hazardous Waste List" (2021 edition), secondary aluminum ash is a hazardous waste.

[0017] Optionally, a support frame is fixedly connected to the upper end of the mixing chamber, and the support frame is fixedly connected to the enclosed hopper.
[0018] By adopting the above technical solution, the support frame supports the sealed hopper.
