Description

TECHNICAL FIELD

[0001] The utility model belongs to mechanical assembly field, and particularly relates to a molten aluminum flow groove baffle of smelting furnace group. BACKGROUND

[0002] The aluminum scrap furnace is the main furnace group for melting aluminum scrap, in the actual production process, after the aluminum scrap is melted into molten aluminum, the molten aluminum cannot be directly used as finished product molten aluminum due to the high slag content in the aluminum scrap liquid, and needs to be statically placed for a period of time before being output. In order to ensure the static time, two static furnaces are matched with one aluminum scrap furnace, so that the aluminum scrap liquid is cyclically statically placed. In order to save space and cost, one Y-shaped flow groove is used between the aluminum scrap furnace and the two static furnaces for molten aluminum conveying. In order to ensure that the molten aluminum can be accurately introduced into the specified static furnace during each molten aluminum conveying process, the operator needs to use a baffle to block the other channel before each molten aluminum conveying, so as to prevent the molten aluminum from entering the other static furnace and affecting the static effect of the molten aluminum and the quality of the molten aluminum. If too much molten aluminum flows in, it will cause aluminum running, overflow and other phenomena, which will damage personnel and equipment.

[0003] Due to the lack of a special molten aluminum baffle, heat insulation cotton is usually used to block the flow groove, and the heat insulation cotton needs to be folded and repeatedly compacted in the flow groove before each use. However, since the heat insulation cotton is a fibrous material, part of the compacted heat insulation cotton will be broken and the slag will be removed when the molten aluminum conveying is completed. The operator needs to clean the broken slag, which is very time-consuming and will shorten the service life of the heat insulation cotton. If the broken slag is not cleaned thoroughly, it will enter the static furnace with the next molten aluminum conveying and pollute the molten aluminum in the furnace. During the repeated removal and placement of the heat insulation cotton, the high-temperature steam in the flow groove after the molten aluminum conveying will increase the risk of scalding the operator.
