Furthermore, the lowest point of the degassing chamber and the standing chamber is provided with a discharge hole.

Further, the molten aluminum outlet launder is of a U-shaped structure and is butted with the outlet of the standing chamber. The aluminum liquid flows out of the outlet flow groove and is subjected to online degassing and filtering.

Furthermore, the lowest point of the degassing chamber and the standing chamber is provided with a discharging port, and when the device works, the discharging port prevents the aluminum liquid from flowing out of the discharging port through a plug. After the equipment works, the aluminum liquid remained in the equipment is discharged through the discharge port, so that the equipment is convenient to clean. And a plug frame for preventing and fixing a plug is arranged on the box body iron shell.

The aluminum liquid enters the degassing chamber from the aluminum liquid inlet launder, and enters the filtering chamber after degassing through the filtering gauze; and the aluminum liquid further removes slag inclusion through the filter type filter plate, enters the standing chamber and smoothly flows out of the equipment through the outlet launder in the standing chamber.

Compared with the prior art, the beneficial effects of the utility model are that: the molten aluminum degassing and filtering integrated equipment provided by the utility model is provided with the degassing device and the filtering device at the same time, thus solving the technical problems of large occupied space and large investment of the existing equipment; the device has the advantages of simple structure and convenient operation, is very suitable for enterprises and production lines with small fields which have low requirements on the hydrogen content and slag inclusion of products, and has great economic benefit.
