Problems solved by technology
However, an obvious defect of the trough-type online degassing equipment is that the liquid level in the degassing chamber is not deep enough, which weakens its degassing effect
In order to obtain a sufficient depth of molten aluminum, the usual practice is to reduce the height of the bottom of the degassing chamber so that it is lower than the bottom of the launder at both ends, so as to obtain a sufficiently deep liquid level, but at the same time the disadvantage is that the casting ends When there is aluminum liquid residue in the degassing chamber, resulting in metal loss

Embodiment Construction
[0022] Below in conjunction with accompanying drawing, technical scheme of the present invention is described as follows:
[0023] like figure 1 , figure 2 , image 3 , Figure 4 As shown, the degassing upper cover 3 is hoisted on the lifting mechanism 2. After the work starts, the degassing upper cover 3 can be lifted to a sufficient height by the lifting mechanism 2 to avoid interference with the degassing tank 1. The degassing groove 1 is hinged on the tilting mechanism 4, and the two ends of the degassing groove 1 are equipped with a rotating shaft 11, and the degassing groove 1 is installed on the support of the tilting mechanism 4 through the rotating shaft 11, and the tilting mechanism 4 is provided with a push arm. The degassing tank 1 is rotated back and forth between the degassing position 6 and the emptying position 7 around the rotating shaft 11 .
[0024] In addition to the air flow groove 1, there is a flow groove liner 5, the bottom surface of the flow groo...

Abstract
The invention discloses a launder type online degassing apparatus with a tip-over function. The launder type online degassing apparatus is composed of a degassing launder, a lifting mechanism, a degassing upper cover and a tip-over mechanism; the degassing launder is hinged to the tip-over mechanism, the degassing launder can rotate back and forth between a degassing position and an emptying position with a rotating shaft as the center through the tip-over mechanism, the degassing upper cover is lifted on the lifting mechanism, the lifting mechanism can lift the degassing upper cover to the enough height, a launder lining is embedded in the degassing launder, molten aluminum flows through a degassing chamber formed by an inner cavity of the launder lining, and meanwhile the degassing treatment is carried out. The tip-over technology is applied to the launder type online degassing apparatus, meanwhile the lining structure of the launder is improved, new design is formed, it can be ensured that the liquid level in the degassing chamber is enough large, residual molten aluminum in the degassing chamber during casting finishing can be avoided, and the metal losses are reduced while the excellent degassing effect is obtained.
Description
technical field [0001] The invention belongs to the technical field of processing equipment for molten aluminum, in particular to a launder-type online degassing equipment with a tipping function. Background technique [0002] In the aluminum processing and aluminum casting industry, in order to produce high-quality aluminum alloy products, it is usually necessary to reduce the hydrogen content in molten aluminum. Currently, the equipment used to realize this process is launder-type online degassing equipment. Compared with the traditional box-type online degassing equipment, the launder-type online degassing equipment has the biggest difference in structure that the bottom of the degassing chamber is flush with the bottom of the launder at both ends, while the degassing chamber of the box-type online degassing equipment The bottom is lower than the bottom of the launder at both ends. Therefore, at the end of casting, there will be no aluminum liquid residue in the degassin...
