Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically to a device for uniformly screening metal additive particles using a multi-layer screen. Background Technology

[0002] Aluminum alloys are currently the most widely used metallic materials. They are generally produced by smelting molten aluminum with the addition of metallic additives. These additives are typically made by mixing granules of metals such as iron, manganese, and chromium with flux granules and then pressing them into block-shaped products. To ensure the quality of the metallic additives, the granules are usually screened into specific particle size ranges using a screening machine. Existing screening machines suffer from problems such as unreasonable feed flow control, low screening efficiency, unstable particle size range ratios, and localized high screening loads that easily damage the screen. Utility Model Content

[0003] The purpose of this invention is to provide a multi-layer screen for uniformly screening metal additive particles, so as to solve the problems mentioned in the background art.

The lower end of the connecting pipe is connected to the storage pipe, the lower end of the storage pipe is equipped with a butterfly valve, the lower end of the butterfly valve is connected to a dispersing cylinder, and the side end of the dispersing cylinder is connected to multiple guide channels.
