Description

FIELD OF THE INVENTION [0001] The present invention relates to an apparatus for selecting iron and non-ferrous metals in waste metals,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal sorting apparatus, and more particularly, to an apparatus for sorting iron and non-ferrous metals in waste metal, which can easily sort metal pieces and powder generated after metal cutting by size and material .

In general, metal cutting can be roughly classified into mechanical cutting that generates chips according to the method and melting by heat. The fusing method has a metal that is not smooth and does not become a melting point as compared with a mechanical cutting, but it is used conveniently because it is possible to cut a hard-to-cut mechanical structure.

1. Arc cutting

It is convenient for cutting metal which is difficult to cut gas such as cast iron, brass, etc.

(1) Carbon arc cutting: Cutting by arc heat generated between electrode and base metal by using carbon rod as electrode

(2) Metal Arc Cutting: In case of direct current due to arc heat generated between special coated metal rod and base metal, positive polarity is adopted.

(3) Oxygen arc cutting: An arc is generated between the coated electrode and the base material,

(4) Inert gas Arc cutting: MIG cutting and TIG cutting are available.

(5) Plasma arc cutting: melted and blown by a plasma of electrically conductive gas

2. Laser beam cutting

It is used for cutting and punching of sheet metal, but its equipment is expensive and its energy consumption is high. It is used for trimming of body panels in automobile factories.

3. Gas cutting

Most of the melting is oxygen-gas cutting. In non-ferrous metals, the melting is performed by dissolving the melting end of the molten metal. However, in the cutting of iron, the mixed gas is preheated to about 800 to 1000 ° C., When oxygen is injected at high pressure, iron is oxidized (burned) at high temperature by intense chemical reaction, and the air stream blows iron oxide, resulting in grooves of 2 to 4 mm width.

When the metal plate is cut according to the fusing method as described, a metal melt portion is generated in a heated portion of the metal plate, and the molten metal portion flows downward due to gravity and is removed. As a result, .

Here, in the process of cutting a metal plate made of iron or non-ferrous material, when the molten metal flows down, or when metal chips or metal powder are accumulated, it is recovered and sold to a sorting company for recycling waste metal. In case that metal is purchased on the basis of different unit price for metal pieces and metal powder on the assumption that the metal is the same material and metal materials such as iron and aluminum are wrongly purchased on the basis of different unit price, There is a difficulty in classifying the waste metal generated after the work by size and material.
