Description

Technical Field

[0001] The utility model relates to the technical field of aluminum raw material screening, in particular to a vibrating screening device for recycled aluminum raw materials. Background Art

[0002] Recycled aluminum is an aluminum alloy or aluminum metal obtained by remelting and refining scrap aluminum and aluminum alloy materials or aluminum-containing waste. It is an important source of metallic aluminum. Recycled aluminum mainly appears in the form of aluminum alloy. When producing recycled aluminum, it is necessary to carry out melting and other steps to produce better raw materials. Before smelting the scrap aluminum, various scrap aluminum parts need to be sorted or disassembled to separate the iron and other non-ferrous metal parts, and then properly formulated and processed to achieve the required recycled aluminum and aluminum alloy composition. Aluminum chips almost all contain a mixture of water, grease and dust, and need to be dried and evaporated in advance before screening.

[0003] The Chinese patent publication number is CN217432211U, and the authorization announcement date is September 16, 2022. A vibrating screening device for recycled aluminum raw materials specifically relates to the field of recycled aluminum processing technology, including a box body, support plates are installed near the bottom on the left and right sides of the box body, and two support legs are installed below the two support plates. A movable door is movably installed through a hinge near the bottom of the front side of the box body, and a handle is installed on the front side of the movable door. A feed hopper is inserted at the top of the box body near the left side; the utility model utilizes the mutual cooperation between the set heating plate, stirring mechanism and scraping mechanism, and can heat and dissipate heat through the heating plate, so as to evenly dry the aluminum raw materials for easy screening. The aluminum raw materials can be stirred by the stirring rod to achieve better drying effect and faster drying rate. At the same time, the scraping bar can scrape off the aluminum raw materials attached to the inner wall of the drying box, and the scraping bar is made close to the inner wall of the drying box by the rebound force of the first spring. At the same time, the force generated during scraping can be buffered for easy use.

The screening mechanism is fixedly installed and is not convenient to replace. The screening method is single, which reduces the screening effect of the recycled aluminum raw materials and cannot meet the use requirements. Utility Model Content
