A vacuum suction aluminum transfer system for casting

Abstract

The invention discloses a vacuum aluminum sucking transfer system for casting. The vacuum aluminum sucking transfer system comprises a vacuum molten aluminum sucking device and a molten aluminum transfer ladle, wherein the vacuum molten aluminum sucking device comprises a base (1), a support frame (4) and an aluminum sucking pipe (9); the aluminum sucking pipe (9) and a venturi (3) are arranged on the support frame (4); pipe bodies of the aluminum sucking pipe (9) and the venturi (3) at one ends respectively penetrate through the support frame (4) and a pipe hole of a sealing gland (2) and are connected; the sealing gland (2) is connected with the support frame (4) above the sealing gland (2) through a connecting rod (10); the lower side of the sealing gland (2) is right opposite to a transfer ladle platform of the base (1); the molten aluminum transfer ladle is put on the transfer ladle platform; and when molten aluminum is sucked, the sealing gland (2) is in sealed connection with the opening of the molten aluminum transfer ladle through a transition flange (14) of the molten aluminum transfer ladle. The process of taking out and transferring the molten aluminum is implemented in a sealed environment, and the vacuum aluminum sucking transfer system is convenient, stable, safe and efficient.

Description

technical field [0001] The invention belongs to the technical field of casting, and relates to a technology for absorbing aluminum liquid by vacuum and using a liquid aluminum transfer bag to transfer the aluminum liquid during the production of aluminum alloy castings, in particular to a vacuum aluminum suction transfer system for casting. Background technique [0002] At present, in the production of aluminum alloy castings, most of the aluminum alloy liquid used is taken out from the melting furnace or the holding furnace in ordinary transfer bags and then sent to the casting process. Because the usual way of transferring aluminum alloy liquid is to release it from the furnace through the outlet with a plug, and flow into the lower transfer bag through a short chute. Such a device for taking out molten aluminum is actually a short chute, and the transfer bag for transferring molten aluminum is also a commonly used transfer bag suitable for turning and lifting. Usually th...

AI Technical Summary

Problems solved by technology

Since the aluminum is taken from the chute at a low position, the flow rate and level of the molten aluminum cannot be well controlled

During the transfer of aluminum water, the aluminum liquid is easy to splash, causing danger

[0003] During the transfer process, the melting furnace or holding furnace and commonly used transfer bags need to be flipped and lifted. Since the melting of molten aluminum belongs to a high-temperature environment, this transfer method has a safety hazard of molten aluminum leakage, which may easily cause unstable lifting operations and even burnout. If the lifting device is damaged, the lifting operation and transfer operation cannot be carried out, and in serious cases, it will cause a safety accident of package tipping and aluminum leakage
