Description

Scrap metal separator by size including waste bins

The present invention relates to a scrap iron separator, which has the effect of increasing the recycling efficiency of useful resources and preventing environmental pollution due to disposal by sorting iron lumps generated from waste buildings, waste materials, etc. through a series of devices. It is about the scrap metal separator.

In the case of dismantling of buildings or various structures, or recycling of abandoned electric poles, the reinforcing bars are separated from the concrete and recovered as scrap iron. In this way, the amount of regenerated scrap metal is large, which makes it a valuable industrial resource. The conventional scrap metal separator has a simple structure equipped with a hammer, and waste concrete is put therein and the scrap metal is separated by hitting with a hammer.

As described above, in the conventional case, it was a device for separating and recycling only a large lump of scrap iron, and there was a problem in that scrap iron scrap generated in the process is discarded as it is. That is, the scrap iron lumps are easy to sort and can be recycled without a special device. However, it was not possible to recover the scrap iron from the concrete fragments generated in the process of separating the large lumps of scrap iron or from the scrap iron scrap mixed with sand and dust. Therefore, an object of the present invention is to solve the problem of the waste of valuable industrial materials and the problem of environmental destruction due to the waste.

In order to achieve the above object, the present invention installs a plurality of screens to recover bulky scrap, and provides a series of devices for separating scrap iron of all types from dust by attaching small particles of scrap iron. will do

According to the present invention, it is possible to separately obtain only scrap iron by separating all types of scrap iron having different volumes from scrap iron waste, thereby recovering all scrap iron of a small volume that was discarded. In addition, since only scrap iron can be easily recovered by a series of automated devices, the efficiency of recycling as an industrial resource is increased, and environmental pollution caused by disposal can be prevented.

The scrap iron separator according to the present invention is an apparatus for separating bulky or small scrap iron from impurities such as sand and soil, and separating impurities as impurities and scrap iron as scrap iron. In order to separate only the scrap metal from the pile of scrap metal mixed with impurities in this way, a plurality of screens and a kenveer are passed through, and the device configuration as an embodiment for achieving this purpose is as follows. A vibrating screen that separates a large volume of scrap metal and discharges foreign substances is installed at the bottom of the vibrating screen, receives and moves a small volume iron piece that has passed through the vibrating screen, and the roller that winds up the belt is a magnetic roller Conveyor Located above the magnetic roller of the iron piece conveyor, an electromagnet is installed in the inner space of the circulating belt, and protrusions are formed on the outer surface of the belt at regular intervals. The impurity ramp and the iron ramp installed in opposite directions to the lower part of the magnetic roller of the iron piece conveyor as an iron piece ramp for transporting the falling iron piece after the impurity conveyor installed at the lower part of the impurity ramp. It is configured to include a waste container connected to the outlet and the impurity conveyor to convey the iron conveyor. The vibrating screen is installed in the lower part of the primary screen inclinedly installed, has a grid smaller than the grid size of the primary screen, and includes a secondary screen installed inclinedly, and the outlet is installed in the lower part of the secondary screen do. According to the above configuration, the scrap metal piles of relatively large size are sorted by the primary screen and then moved to the place where the scrap metal is collected through the discharge ramp, and the relatively small iron pieces are filtered by the secondary screen and then self-attached. It is separated from foreign substances by a sorter. The above process will be described in detail as follows. The scrap metal pile is fed into the upper part of the vibrating screen. The nodules with the largest volume are filtered through the primary screen and moved by vibration in an inclined direction along the upper part of the primary screen. The lattice size of the primary screen is suitable to the extent that 40 mm or more of scrap iron can be separated. The iron pieces passing between the grids of the primary screen are placed in the secondary screen located below the primary screen. The grid size of the secondary screen may be sufficient to separate scrap metal of about 10 to 40 mm. Therefore, the iron pieces filtered by the secondary screen are moved along the slope by vibration, and are moved by falling onto the iron piece conveyor. Those of 10 mm or less that pass through the grid of the secondary screen are sent to the waste bin through the discharge path because of their low usefulness in terms of efficiency in terms of the recovery of scrap metal. The iron pieces moving along the iron piece conveyor are sorted by a magnetic separator installed at the top of the end of the conveyor. And the remaining ones that are not magnetically removed are separated again by the magnetic roller of the iron piece conveyor. First, the operation of the magnetic separator will be described as follows. The magnetic separator has an electromagnet installed and a belt is circulated around the electromagnet. A plurality of protrusions are formed on the outer surface of the belt, and the iron piece attached to the belt by the electromagnet is pushed down to a range where the magnetic force of the electromagnet is weakened. Therefore, the iron piece attached to the belt falls to the lower iron piece ramp by the movement of the belt and the action of the stone. The pieces of iron that have fallen down the ramp are placed in a container for collecting scrap iron. The remaining ones that are not attached to the magnetic separator are moved to the end of the string of the iron piece conveyor. Since a magnetic roller is installed at the end, the iron piece among the rest moving along the belt is magnetically attached even if it moves downward by the magnetic roller, so it does not fall. . The iron that has fallen on the iron ramp is moved to the container for collecting scrap iron again by the iron conveyor. Foreign substances, including non-ferrous metal, sand, soil, etc., which cannot be moved by the magnetic roller, freely fall from the end of the magnetic roller, fall down the impurity ramp, and then ride the impurity conveyor to the waste bin. Through a series of steps as described above, scrap iron, iron shards, and iron worth recycling are recovered from the scrap pile, and the rest are disposed of.
