Description

Technical Field

[0001] The present application relates to the technical field of aluminum liquid slag removal, and specifically to an aluminum liquid slag removal device for aluminum alloy castings. Background Art

[0002] Aluminum is a silvery-white light metal and the most abundant metal element in the earth's crust. Cast aluminum is a commonly used metal in the foundry industry. During the aluminum casting process, in order to reduce impurities in the aluminum liquid and improve the quality of aluminum, slag-forming agents are used to effectively separate the metal and impurities, and the impurities are formed into slag, which is then removed manually or mechanically. The addition of slag-forming agents, stirring, and slag removal are three independent steps that require different workers or equipment to complete different steps.

[0003] Patent No. CN213866379U discloses a slag removal device for aluminum alloy casting production. The slag removal device for aluminum alloy casting production is improved in structure, so that when the device is actually used, the slag particles of the slag-forming agent in the aluminum liquid can be collected and discharged to the outside when the aluminum liquid is scooped out, and the aluminum liquid can be returned to the inside of the device to avoid wasting the aluminum liquid, reducing subsequent manual operations, and the device can be cleaned during actual use to avoid the aluminum liquid from accumulating in the device as the aluminum liquid settles over time, thereby improving the practicality of the device. However, the device cannot guarantee that all slag can be completely absorbed, and it is easy to have a phenomenon that all the aluminum liquid is extracted but large particles of slag are left in the aluminum liquid pool. The slag removal efficiency is low, and manual real-time observation and assistance are required, and the purpose of reducing manual participation is not achieved. Utility Model Content
