Description

[0001] The present invention relates to a compression apparatus for wasted scrap,

The present invention relates to a scrap iron for waste disposal, and more particularly, to scrap iron having various components such as steel or aluminum among various wastes discharged from general households, shopping malls, and reconstruction sites including various industrial sites, And more particularly, to a scrap compression apparatus for waste which can be easily transported and handled after minimizing its volume, and in particular, capable of increasing compression production efficiency.

Wastes such as waste tires, rubber, waste vinyl, synthetic resins, carpets, clothes, duvets, etc., waste wood, waste plastics, and PCBs, which are generated in daily life or in industrial sites, are recycled, incinerated or buried Among various wastes discharged from general households, shopping malls and reconstruction sites including various industrial sites, scrap metals having components such as iron or aluminum are collected and recycled through melting.

However, these wastes are heavy and bulky, which makes it difficult to collect and transport the wastes, resulting in a high cost, shortening the life of the landfill, and inconveniencing the incinerator and the furnace.

Therefore, in the case of general wastes, it has been generalized to dispose of wastes by minimizing the volume of waste after landfilling or incineration. In the case of scrap iron, the scrap is produced as a bundle of scrap iron by minimizing the volume and then transporting it to the furnace Or in some cases, it is cut into a predetermined size using a separate cutter, and then melted in a furnace.

In the above, a variety of gypsum compressors have been proposed in the past. Among them, the gyroscope compressor disclosed in Korean Utility Model Publication No. 1989-0001864 has two hydraulic cylinders mounted on both sides of the gas, And a hydraulic cylinder is mounted on a central rear surface of the base plate. A shaft having a plate is mounted on the front side of the base plate. A hydraulic cylinder mounted on the center of the upper portion of the base is connected to a shaft, A cover plate is opened and closed by a shaft of a hydraulic cylinder which is inserted into the ledge grooves and protruded from the supporting table, and is fixed to the base body as a hanging hook, When the compression operation is completed, the opening and closing door ring is opened, and the hydraulic cylinder shaft mill By pushing it on top of the other hand the gas to be extruded in front is to configure the control device to operate each hydraulic cylinder is installed.

However, in the case of a scraper compressor having such a structure, the upper opening of the gas is simply closed through the lid, the both sides are compressed through the hydraulic cylinder and the plate, then the front opening is opened and the rear plate is pushed through the hydraulic cylinder, In addition, since the scrap is compressed only on both sides without being compressed in all directions, the volume of the scrap can not be significantly reduced. As a result, the compressed scrap bundle as described above has a relatively large volume and a large weight, so that handling and transportability are not very good. When a scrap bundle having a large volume is directly introduced into a furnace and melted, The power consumption due to the heating of the scrap iron is high and the cost of regeneration of the scrap metal becomes high.

On the other hand, Korean Patent Registration No. 0870721 discloses a method of compressing waste scrap in front and rear, left and right directions, and automatically cutting the compressed bundle into a desired shape, thereby greatly reducing the volume of scrap for disposal, There is proposed a hydraulic compression and auto-cutting apparatus which facilitates the operation of the apparatus.

However, in such compression and automatic cutting apparatuses, there are a plurality of hydraulic cylinders for compressing the scrap bundles in the left and right direction in order to drastically reduce the volume of the scrap bundle, and in particular, a cutting apparatus and a cutting apparatus driving apparatus There is a problem that the apparatus is increased as a whole due to the provision of the hydraulic cylinder, the manufacturing cost of the apparatus is increased, and a large number of hydraulic cylinders must be driven organically so that the maintenance cost is significantly increased.

In addition, since the conventional scrap iron for scrapping and cutting apparatus for waste is sequentially subjected to a process of compressing scrap iron, a process of cutting compressed scrap and a process of discharging scrapped scrap sequentially, Is very low.
