Description

Technical Field

[0001] The utility model relates to the field of hub manufacturing, and particularly relates to a remelting eddy current aluminum melting furnace for aluminum chip recycling. Background Art

[0002] A hub refers to a component installed on the vehicle axle for supporting the tire and transmitting the vehicle body load. The hub not only needs to have sufficient strength and rigidity in structure, but also has a certain aesthetic property, because it is directly related to the driving safety and aesthetic property of the vehicle. According to different materials and manufacturing processes, hubs can be divided into steel hubs and alloy hubs. Nowadays, vehicle hubs are generally made of aluminum alloy, which has the advantages of light weight, good heat dissipation performance, diverse shapes, strong aesthetic property, and can improve the vehicle's handling performance and fuel economy.

[0003] During the production of aluminum alloy hubs, a large amount of aluminum chips and aluminum blocks will be generated. A large amount of aluminum chips will be produced in the processes of turning and drilling of the hubs. Aluminum chips are important recyclable resources. They can be centrally collected and then remelted to save production costs. The remelting of aluminum chips generally uses a melting furnace for heating and remelting, and then solidifies into aluminum blocks for reuse. During the remelting process of aluminum chips, a large amount of heat energy is required to melt them. When the aluminum chips enter the melting furnace, they first fall on the surface of the molten aluminum in the furnace and are easily ignited and burned under the heating of the furnace, forming black slag that cannot be recycled and used, resulting in a large amount of waste. Moreover, when the black slag is mixed in the molten aluminum and pressed into aluminum blocks, it will reduce the quality of the aluminum blocks and cause a decrease in purity.

A motor 9 is provided on the second extension plate 3b, and the rotating shaft of the motor 9 passes through the second extension plate 3b and extends to the bottom of the second extension plate 3b. A second synchronous wheel 9a is provided at one end of the rotating shaft of the motor 9, and a synchronous belt 10 is provided between the first synchronous wheel 8 and the second synchronous wheel 9a. A waste gas negative pressure cover 11 is provided at one end of the third extension plate 3c, and the waste gas negative pressure cover 11 is fixedly connected to the third extension plate 3c. A screw conveyor 12 is provided on the other side of the aluminum melting furnace body 1, and a material guide plate 13 is provided at one end of the screw conveyor 12. One end of the material guide plate 13 is arranged above the aluminum melting furnace body 1, and a material receiving funnel 14 is provided at the other end of the screw conveyor 12.

[0025] A stirring stabilizing bundle 15 is provided at one end of the stirring shaft 6 close to the first extension plate 3a. The stirring stabilizing bundle 15 is made of asbestos and is wound around the outer wall of the stirring shaft 6 by steel wire. The stirring shaft 6 is driven by the motor 9. The second synchronous wheel of the motor 9 is connected to the first synchronous wheel 8 by a synchronous belt 10 and rotates synchronously.
