A high-temperature aluminum slag processing equipment

Abstract

The invention discloses novel high-temperature aluminum slag rapid processing equipment. A slag barrel is arranged on one side of an aluminum smelting furnace and installed on a rail car which is installed on a rail car traction device. An ash barrel is installed on a rail trolley which is installed on a rail trolley traction device. The rail trolley traction device is located at one end of the rail car traction device, and the horizontal height of the rail trolley traction device is lower than that of the rail car traction device. A lifter is located at the joint of the rail trolley traction device and the rail car traction device. A stirrer is arranged at the upper end of the lifter. A first dust collection device is arranged on the stirrer. A slag barrel overturning driving device is arranged on one side of the lower end of the stirrer and used for corresponding to the slag barrel moved onto the lifter. A second dust collection device is arranged on one side of the lower end of the stirrer. The novel high-temperature aluminum slag rapid processing equipment is easy to operate, low in labor intensity, low in investment cost and considerable in benefit, and the work environment of operators is greatly improved.

Description

technical field [0001] The invention relates to the technical field of aluminum slag treatment, and more specifically relates to high-temperature aluminum slag treatment equipment. Background technique [0002] At present, aluminum rods are used in the production of aluminum alloy profiles in my country, and the main material of aluminum rods is aluminum ingots or aluminum recycling waste, which are smelted and recast into aluminum rods of various specifications. However, during the smelting process of aluminum ingots or aluminum recycling waste, a large amount of slag (mainly alumina) will be produced, and a large amount of molten aluminum is mixed in the slag. After these slags are mechanically (or manually) raked out from the melting furnace, they are generally transported mechanically (or forklifts) to another area for manual and simple mechanical stirring to separate the molten aluminum from the slag. [0003] When using this method to process slag, there are following...

AI Technical Summary

Problems solved by technology

[0003] When using this method to process slag, there are following disadvantages: 1. During the transfer process of slag, due to the decrease of slag temperature, the fluidity of molten aluminum is deteriorated, so that the separation of molten aluminum and slag is not clean, and only part of the molten aluminum is separated. The molten aluminum is finally mixed with the slag and treated as waste at a low price; 2. The slag is in contact with the air for a long time during the transfer process, causing part of the molten aluminum in the slag to be oxidized again to form slag; 3. The slag just out of the furnace, The smoke and dust are relatively large, and the air is seriously polluted by the smoke and dust during transshipment; 4. The separated aluminum liquid is cooled and solidified and then returned to the furnace for remelting. First, it causes energy waste, and second, it causes aluminum to burn again

[0004] This traditional treatment method has high cost, high labor intensity and serious environmental pollution.
