[0019] As Figures 1-5 Indicated, the device of the application scheme can stably operate in high-temperature environment (400-900 ℃), and has the functions of molten aluminum circulation and vertical lifting. It is suitable for aluminum smelting, casting and aluminum alloy recycling industry.

[0020] Pump chamber 1 is made of silicon carbide and alumina materials resistant to aluminum corrosion by adding high-temperature binder, and is integrally poured. The circulation pump chamber cavity 15 is used for molten aluminum circulation, and the lifting pump chamber cavity 14 is used for vertical lifting of molten aluminum. The pump chamber 1 has high-temperature resistance below 1000 ℃, is resistant to aluminum corrosion, and has a service life of more than five years.

[0021] The device of the application scheme works through the lifting motor 10, drives the elevator head 7 to move up and down along the vertical guide rail 26 through the lifting chain 9, rotates the whole elevator head 7 with the lifting column 5 through the forward or reverse rotation of the rotation motor 6 when it moves to the highest position, and switches the position of the elevator head 7 above the lifting pump chamber cavity 14 and the circulation pump chamber cavity 15. When the elevator head 7 is in the position of the lifting pump chamber cavity 14, the lifting motor 10 works in reverse to drive the elevator head 7 to descend, and the impeller 2 is driven into the lifting pump chamber cavity 14 through the metal spindle 12 and the rotating rod 13. The impeller drive motor 11 works to drive the impeller 2, and the rotation of the impeller 2 can lift and discharge the molten aluminum in the lifting pump chamber cavity 14 through the lifting pump water outlet 16 into the aluminum flow groove leading to the casting tray.

[0022] As the above operation, when the need to lift the aluminum liquid, the need for aluminum liquid circulation, impeller 2 to move to the circulating pump chamber cavity 15, under the action of impeller 2, accelerate the circulating pump chamber cavity 15 into the aluminum liquid into the aluminum liquid pool.

[0024] The bottom of the circulating pump chamber cavity 15 and the circulating water outlet 17 is provided with a bottom channel 18 communicating the bottoms of the two, and the bottom channel 18 is communicated to the aluminum liquid pool through the pump chamber water inlet.

[0025] The pump chamber 1 is integrally casted by using silicon carbide and alumina materials resistant to aluminum corrosion and adding high-temperature binder.

[0026] The rotary motor 6, the lifting motor 10 and the impeller driving motor 11 are electrically connected with a PLC control cabinet through wires.
