Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The invention will now be further described with reference to the accompanying drawings.
As shown in figure 1, a degassing and stirring device on an aluminum alloy foil production line comprises a stirring box 1, the stirring box 1 is sequentially divided into a left side chamber 3, a middle chamber 4 and a right side chamber 5 by two partition boards 2 from left to right, the upper part of the left side chamber 3, the upper part of the middle chamber 4, the lower part of the left side chamber 3, the lower part of the middle chamber 4, the upper part of the right side chamber 5 and the lower part of the middle chamber 4 are respectively communicated, a discharge hole 6 is arranged at the lower part of the left side chamber 3, a feed hole 7 is arranged at the upper part of the right side chamber 5, a lifting plate 8 which is horizontally arranged is arranged in the middle chamber 4, the middle part of the lifting plate 8 is connected with a lifting rod 9, the lifting rod 9 is driven to lift by a cylinder 10 which is arranged outside the stirring box 1, the front and rear sides of the lifting plate 8 are respectively close to the front inner wall and rear wall of the stirring box 1, the left and right sides of the lifting plate 8 are respectively close to the two partition boards 2, the inside of two baffles 2 is equipped with breather pipe 11 respectively, and the bottom of baffle 2 is equipped with the gas outlet 12 of intercommunication breather pipe 11 respectively, and breather pipe 11 stretches out from agitator tank 2.
