[0003] The aluminum ash calcining furnace currently in use performs heavy metal removal, loading, calcination and other operations separately. There are many time intervals in the whole process, and staff intervention is required, which reduces work efficiency and is inconvenient to operate. Summary of the invention

[0006] By adopting the above technical scheme, aluminum ash is put into the separation cylinder, and then the principle of electromagnet is used to remove heavy metals in the aluminum ash when the cylinder is controlled to move the iron rod back and forth in and out of the separation cylinder. Then the electric push rod is started, and the support plate rises with the separation cylinder, and then the furnace cover connected to the separation cylinder is opened, and then the telescopic tube at the bottom of the separation cylinder slides down. Since the bottom end of the telescopic tube is aligned with the inside of the calcining furnace, the aluminum ash can be accurately slid into the calcining furnace. After each calcining furnace is filled with raw materials, the movable end of the electric push rod is controlled to retract, and then the furnace cover closes the calcining furnace.

[0014] By adopting the above technical solution, the beneficial effects achieved by the present invention are: 1. In the present invention, aluminum ash is put into the separation cylinder, and then the principle of electromagnet is used to remove heavy metals in the aluminum ash when the cylinder is controlled to move the iron rod back and forth in and out of the separation cylinder. Then the electric push rod is started, and the support plate rises with the separation cylinder, and then the furnace cover connected to the separation cylinder is opened, and then the telescopic tube at the bottom of the separation cylinder slides down. Since the bottom end of the telescopic tube is aligned with the inside of the calcining furnace, the aluminum ash can be accurately slid into the calcining furnace, and then after each calcining furnace is filled with raw materials, the movable end of the electric push rod is controlled to shrink, and then the furnace cover closes the calcining furnace, and the stripping of heavy metals and loading can be done in one go, which not only reduces the calcining time of the aluminum ash, but also improves the comfort of use.
