Description

Technical Field

[0001] The utility model relates to the technical field of rotary furnace melting treatment for aluminum slag recovery, and particularly relates to a rotary furnace aluminum hot slag recovery device. Background Art

[0002] A rotary furnace is a device for melting and treating aluminum slag for recovery. When melting and treating aluminum slag, the aluminum slag is first put into the rotary furnace, and the aluminum slag is melted by the continuous rotation and heating of the rotary furnace. Finally, the aluminum liquid in the rotary furnace is poured out.

[0003] After the aluminum liquid is poured out, there is still a large amount of aluminum hot slag and some aluminum liquid in the furnace, and the aluminum hot slag needs to be promptly poured into the slag hopper. The existing slag receiving hopper is used to hold the aluminum hot slag and then transfer it to other processes for aluminum slag recovery. The aluminum liquid mixed in the aluminum hot slag will always be mixed with the aluminum slag and cannot be separated. As time goes by, the aluminum liquid will solidify on the aluminum slag. If it is to be recovered, it needs to be smelted in a secondary re-melting furnace. Repeated smelting like this wastes gas energy, reduces production efficiency, increases production costs, and reduces the resource recovery rate. Summary of the Invention

[0004] The utility model aims to solve the problem that the aluminum liquid in the aluminum hot slag cannot be recovered during the existing rotary furnace aluminum hot slag recovery process and is repeatedly smelted after solidification, and provides a rotary furnace aluminum hot slag recovery device, which can separate the aluminum slag and the aluminum liquid during the aluminum hot slag recovery process, increase the aluminum output, and reduce the waste of gas energy.

[0005] To achieve the above object, the technical solution of the utility model is as follows:

[0006] A rotary furnace aluminum hot slag recovery device includes a slag filtering hopper, a discharging hopper platform, and a liquid collecting housing arranged in sequence from top to bottom. The slag filtering hopper is arranged on the discharging hopper platform. A filtrate hole is arranged at the bottom of the slag filtering hopper, and a filtrate port matching the filtrate hole is arranged on the discharging hopper platform. The liquid collecting housing is arranged below the discharging hopper platform, and the top of the liquid collecting housing is open, and the opening corresponds to the filtrate port. The aluminum liquid in the slag filtering hopper flows into the liquid collecting housing to realize the separation of the aluminum hot slag and the aluminum liquid, and the aluminum liquid is collected for secondary utilization.

[0007] Furthermore, the discharging hopper platform is arranged at the rotary furnace outlet. The discharging hopper platform includes a platform plate and support columns. The support columns are arranged below the platform plate and fixedly connected to the platform plate. The filtrate port is opened on the platform plate. The slag filtering hopper is placed on the discharging hopper platform.

[0008] Further, the slag filter hopper includes a hopper-shaped liquid storage tank. A support plate is fixedly arranged at the bottom of the liquid storage tank. A plurality of connecting plates for supporting the liquid storage tank are evenly arranged between the support plate and the inclined surface of the liquid storage tank. The connecting plates are perpendicular to the support plate. The connecting plates are used to connect the liquid storage tank and the support plate.

[0009] Further, a plurality of supporting feet are arranged below the support plate. The supporting feet suspend the support plate on the discharging hopper platform. This prevents the molten aluminum from adhering between the support plate and the discharging hopper platform during the falling process, avoiding the adhesion of the support plate and the discharging hopper platform.

[0010] Further, the liquid collection housing is in a shape of an ingot. The connections between the bottom surface and the side surfaces of the liquid collection housing are all rounded. The rounded setting makes it easy for the solidified aluminum ingot to demold from the liquid collection housing.

[0011] Further, the area of the opening at the top of the liquid collection housing is larger than the area of the filtrate port, and the area of the filtrate port is larger than the area of the filtrate holes. This prevents the molten aluminum from dripping outside the liquid collection housing, reducing resource waste.

[0012] By the above technical solutions, the beneficial effects of the present utility model are as follows:

[0013] The slag filter hopper, discharging hopper platform, and liquid collection housing are sequentially arranged from top to bottom in the present utility model. The aluminothermic slag in the rotary furnace is poured into the slag filter hopper. The molten aluminum mixed in the aluminum slag flows through the filtrate holes of the slag filter hopper into the liquid collection housing below the discharging hopper platform. During the process of collecting the aluminum slag, the collection of the residual molten aluminum is completed, preventing the molten aluminum from solidifying in the aluminum slag, increasing the aluminum output, and avoiding the waste of gas caused by repeatedly smelting the aluminum slag.
