Description

Method for disposal of waste mather on the spot and its apparatus}

The present invention is an environmentally friendly waste that can be separated, selected and recycled from the construction site waste and landfill waste mixed with soil, concrete, rebar, waste wood, asphalt, etc. generated in various construction sites It relates to a field treatment method and apparatus, and more particularly, in the preceding process, the wastes crushed to a certain size are put into a vibrating hopper and formed into a perforated rubber net, and the sediment is separated to the bottom through a centrifuge having an inclination. Waste discharged to the conveyor and the centrifuge is discharged to the lift conveyor to drop the waste from the tip of the lift conveyor and transported to the tip conveyor. At this time, a blower is installed at the bottom of the lift conveyor to remove waste (paper, vinyls). ) By the wind discharged from the blower The waste, which is separated from the waste, is dropped onto the end conveyor so that the worker can collect and recycle aggregates such as metals, nonferrous metals, and concrete from the end conveyor.

In general, on-site waste generated at new construction sites and reconstruction sites and wastes embedded in landfills are mixed with soil, concrete, rebar, waste wood, asphalt, rocks, plastics, papers and vinyl wastes.

Conventionally, all of the wastes that can be recycled as described above are disposed of and disposed of in landfills, and thus, there is a problem in that environmental friendliness is destroyed by destroying the natural environment caused by waste of resources and landfilling of wastes. The basic form of the centrifuge (circular sorter) separating and sorting out the same waste by the apparatus is as shown below: ■ Input conveyor → Centrifuge → Discharge conveyor → Blower ↓ Lower conveyor ↓ Is the most basic form that is produced by more than 10 companies around the world and is also produced in Korea. It has the same form as domestic patent application Nos. 10-1996-0012303 and 10-1998-0018930. Using a conveyor to feed waste into the centrifuge, and using a heating burner After the core of the blind hole of the foreign matter separator perforated net burning removed is that centrifugal separation, but when using the input conveyor as described above, the wet waste and dry waste or the same amount is injected into the centrifuge. When dry waste is introduced, the sorting is completed at the input part, and large-sized waste causes damage to the perforated network, and the waste (vinyl, paper, etc.) is crushed, resulting in incorporation into high quality soil. In addition, when wet waste is introduced, it cannot be sorted out and discharged, and high quality soil is discharged along with foreign matters during blowing, which increases the amount of incineration waste.In addition, when the waste is clogged using the burner, the flame is burned and removed. In order to solve the problem of melting and sticking to the centrifuge generated when using the burner, and the method of removing garbage stuck to the flame by using an air nozzle, the problem of pollution generated during combustion using the burner, There are problems in economics due to the provision of separate devices such as an air nozzle and a high pressure air generating device, and an additional process is added. The main reason for using this method is that the material of the centrifuge is made of metal, so it does not fall well when soil is attached to the contact surface.

Therefore, the present invention was created for the purpose of solving the above problems, and it is possible to use the recycled aggregate by sorting and separating the site and landfill waste, and also to minimize the amount of landfill waste to be disposed of. To provide a site treatment method and apparatus therefor.
