Description

Technical Field

[0001] The invention relates to the technical field of aluminum ash calcining, and in particular to an ash screening mechanism and method for aluminum ash calcining. Background Art

[0002] Aluminum ash slag is a by-product of aluminum and aluminum alloy smelting. It is composed of alumina, metallic aluminum or aluminum alloy, slag-forming agent, etc. In the prior art, before calcining the aluminum ash slag, it is necessary to screen the aluminum ash slag to separate pure aluminum and aluminum ash therein. During the screening, a slag screening mechanism is required.

[0003] One of the existing methods for screening aluminum ash slag is to screen it through a vibrating screen. During use, the traditional vibrating screen pours the aluminum ash slag onto an inclined screen and superimposes a vibration effect on the screen to make it fall quickly and screen the components inside. However, this type of vibrating screen often does not have an automatic inclined screen adjustment function, or has no adjustment function or the adjustment operation is relatively complicated. Secondly, the vibration intensity of the screen is difficult to adjust. The aluminum ash slag is stored for a long time and is easy to agglomerate. Conventional vibration intensity makes it difficult to separate the agglomerates, which affects the screening effect of the aluminum ash slag.

[0004] Therefore, we propose a slag screening mechanism and method for aluminum ash calcination to solve the above problems. Summary of the invention
