Description

Technical Field

[0001] The utility model relates to the field of crucible production and manufacturing, in particular to an automatic feeding device for an aluminum-magnesium crucible. Background Art

[0002] Aluminum-magnesium crucibles are neutral crucibles with good thermal shock resistance. They are generally made into prefabricated crucibles or rammed crucibles, which are suitable for smelting products containing titanium-aluminum alloys. They do not have the problems of decomposition under vacuum and water absorption of the furnace lining, and have a long service life. At the same time, from the perspective of economic cost, the aluminum-magnesium rammed crucible has the characteristics of cost saving and long service life. During the manufacturing process of aluminum-magnesium crucibles, the raw material powders need to be mixed and added to the mold for tamping. The raw materials need to be fully mixed and evenly mixed, and the particle diameter of the powder is also required. Some powders may stick together to form larger particles. In order to prevent larger particles from mixing into the mixing machine and affecting the quality of the subsequent crucibles, workers usually filter and screen the powder before putting it into the mixer. This practice wastes labor and is inefficient.

[0003] In view of the above problems, an automatic feeding device for an aluminum-magnesium crucible is designed specifically. Utility Model Content

[0004] The utility model aims at solving the above problems and specifically designs an automatic feeding device for aluminum-magnesium crucible.

[0012] Furthermore, the filtering device includes: a filtering channel, a screen and a vibrator, the filtering channel is fixedly connected to the top of the inner wall of the external shell, the filtering channel is located between the feeding device and the stirring device, the screen is fixedly connected in the filtering channel, and the vibrator is installed on the side of the filtering channel.

[0013] In the above manner, the filtering device can filter the powder falling from the feeding device. After the powder falls onto the screen, the vibrator vibrates and the screen vibrates and screens the powder on it, so that large particles are vibrated and dispersed to meet the mixing standard.

[0014] Furthermore, it also includes an anti-blocking device, which is installed on the top surface of the external shell and placed in the feeding device.

[0015] Furthermore, the anti-blocking device includes: a rotating shaft, a spiral portion and a third motor.
