Embodiment Construction

[0013] The technical scheme of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods, as figure 1 As shown, a device for removing scum in molten aluminum includes a degassing chamber 1, and a choke block 2 is arranged at the outlet of the degassing chamber 1.

[0014] In particular, the choke block 2 is a triangular wedge-shaped block.

[0015] When the present invention is working, a block 2 is provided at the outlet of the degassing chamber 1 . When the aluminum liquid flows to the outlet, due to the existence of the choke block 2, the scum in the aluminum liquid will be blocked by the choke block 2, and a part of the scum will soon adhere to the choke block 2, thus effectively reducing the flow rate of the aluminum liquid. The slag content in the aluminum alloy improves the purity of the aluminum liquid. In addition, due to the addition of the choke block 2, the outlet flow direction...

Abstract

The invention discloses a device for removing dross in aluminium solution, comprising a degassing chamber, wherein a flow-blocking block is arranged at the outlet of the degassing chamber. The device disclosed by the invention has the beneficial effects that because the flow-blocking block is arranged in the degassing chamber, and the flow-blocking block is a triangular wedge-shaped block, the dross in aluminium solution is blocked by the flow-blocking block, and a part of the dross is attached on the flow-blocking block, thus effectively reducing the content of the dross in the aluminium solution, and improving the purity of the aluminium solution.

Description

technical field [0001] The invention relates to a degassing device, in particular to a device for removing scum in molten aluminum. Background technique [0002] In general melting and casting production workshops, a filtering device is equipped behind the degassing equipment to filter impurities in molten aluminum. The principle of the filter equipment is to pass the aluminum liquid through the filter medium inside the equipment to obtain clean aluminum liquid. The filter medium has a certain lifespan. When the filter medium is blocked by impurities to a certain extent and the flow rate of molten aluminum passing through the filter medium does not reach the flow rate required by the subsequent casting machine, it can be considered that the filter medium has been scrapped. Therefore, the purity of molten aluminum passing through the filter medium will affect the life of the filter medium. In order for the filter medium to have a longer service life, we need to do the follo...
