Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mechanically connects an aluminum material chip sorting device and a melting furnace to ultimately realize automation and unmanned waste aluminum material crushing. The present invention relates to a storage and supply device for different types of used chips and a waste aluminum material recycling plant using the same.

2. Description of the Related Art Generally, when recycling waste aluminum material,
Waste aluminum alloy scrap as material (Taint Taber T /
T), waste aluminum cans (UBC), waste engines (mechanical castings), waste sashes, old scraps (pots, pots, etc.) are crushed into 30 to 50 mm square chips by a crushing device (shredder), Dalai powder (aluminum casting chips) is processed in a rotary kiln and sent to a sorting device.

In the sorting apparatus, iron chips such as bolts and nuts may be mixed in the crushed chips depending on the product type, such as a waste engine, so that the first stage It is classified into iron and other (including aluminum) by the magnetic separator which is the sorting device of
Send to the second stage sorter to sort anything other than iron into aluminum and others. In the sorting apparatus in the second stage, aluminum is mainly sorted by applying an eddy current to fly only aluminum.

In this way, the sorted aluminum materials are packed in boxes (containers) according to product type, and those that cannot be directly hung on the crushing device are weighed and transported to the stockyard near the melting furnace. It was doing.

In the above, the introduction of the material to the crushing device and the introduction of the crushed chips to the sorting device were carried out by a belt conveyor arranged between these devices, but from the sorting device to the stockyard near the melting furnace. It was transported by a forklift.

Then, after the chip-shaped material is put into a melting furnace and melted, it is introduced into a holding furnace through a runner, and in this case, silicon, copper, iron, magnesium, manganese, etc. are mixed with the melted aluminum to a certain degree. It is added and stirred according to the compounding ratio (wt%), and alloying work is performed with these active ingredients.

After the alloy work is completed in this way, an ingot is manufactured by a casting machine, and the ingot after demolding is subjected to a series of treatments such as cooling, packing, weight measurement, and product numbering, and then the ingot is made into a variety. It is stored and swirled separately.

Therefore, in the process of producing (regenerating) an ingot using these waste aluminum materials, which has been generally carried out in the past, the steps from the crushing apparatus to the sorting apparatus and the steps from the melting furnace to the casting are almost completely automated. It can be said that the process from the sorting device to the melting furnace is
The reality is that it is not automated at all.

[0009]

Therefore, in order to transport the crushed waste aluminum material from the sorting device to the melting furnace, it is necessary to first pack a large number of boxes for transporting the waste aluminum material. For example, if one charge is 100 t. Since a 24-hour operation requires at least 3 charges, the number of boxes used for this is quite large, and not only preparation of this box but also management has been a major issue. However, the bigger issue was that it required a lot of manpower.

In the case of further melting work, it is inconvenient that the weight of this material must be artificially measured on the basis of a preliminarily prepared blending table. Need material transportation,
This transportation is usually carried out by a forklift, but this not only increases the number of forklifts inevitably,
This is not only complicated for transportation, but also dangerous, because the material cannot be put in unless it comes close to the high-temperature melting furnace.

[0011]

In order to solve the above-mentioned problems, the waste aluminum material crushed chips storage / supply device according to product type according to the present invention (claim 1) is used to solve the above problems. A plurality of hoppers to be stored separately are arranged, above the input port of this hopper, a belt conveyor is arranged which reciprocates over each input port of all the hoppers while rotating, and below the discharge port of the hopper, A hopper scale that reciprocates over each discharge port of all the hoppers is arranged.
