Description

Technical Field

[0001] The utility model relates to the technical field of aluminum separation from slag, in particular to an aluminum separation device for garbage incineration slag. Background Art

[0002] The slag from municipal solid waste incineration power plants is mainly an inhomogeneous mixture of stones, sand, glass, ceramics, ash, metal and a small amount of unburned garbage. After crushing and sorting, the slag has stable chemical properties, good durability and high strength. Slag is a general waste without toxicity and can be directly landfilled or processed and utilized. The slag after technical treatment is suitable for making unburned bricks or other building materials and has a certain recycling value. A certain amount of aluminum metal and other fixed mixtures exist in the processed products of waste incineration slag. The aluminum contained in the slag can be sorted by an eddy current separator. Scrap aluminum is a valuable resource. The effective recycling and utilization of scrap aluminum is of particular importance to the development of a circular economy, saving resources and energy, and reducing greenhouse gas and harmful substance emissions.

[0003] Currently, eddy current separators are commonly used to recover aluminum metal from slag. This is because when aluminum passes through a non-ferrous metal eddy current separator, it generates eddy currents and produces a reverse magnetic field force that repels the eddy current separator's own magnetic field, causing it to fly out of the slag.

[0004] However, when using a traditional eddy current separator, since the slag contains a small amount of magnetic metal, the magnetic metal will be mixed together with the aluminum metal when it is recovered, which affects the recovery effect of the aluminum metal. At the same time, when the slag is transported on the conveyor belt, the slag is easily accumulated on the conveyor belt, making the slag on the conveyor belt insufficient to disperse, resulting in poor aluminum metal recovery effect.

The second motor 23 drives the roller 3 to rotate. The rotation of the roller 3 drives the conveyor belt 2 to rotate. The rotation of the conveyor belt 2 drives the sorting magnetic roller 4 to rotate.

[0034] The end of the vibrating feed hopper assembly 9 is located above the right end of the conveyor belt 2 , so that the vibrating feed hopper assembly 9 can effectively transport the slag to the conveyor belt 2 .

[0035] In the present utility model, the slag is dispersed and falls onto the conveyor belt 2 through the vibrating feed hopper assembly 9, and the second motor 23 drives the roller 3 to rotate, and the rotation of the roller 3 drives the conveyor belt 2 to rotate, and the rotation of the conveyor belt 2 drives the sorting magnetic roller 4 to rotate, and the rotation of the conveyor belt 2 drives the slag on it to move.
