Description

Apparatus for Recycling of Concrete Scraped Material including Waste Wood

The present invention relates to a recycling treatment apparatus capable of obtaining soil, stone dust and aggregate of a desired size by crushing building waste containing waste wood, and more particularly, to crushing and sorting construction waste to produce soil, stone dust and aggregate. It relates to a recycling treatment device for building wastes, including waste wood, that can provide good supply and demand for stone dust and gravel required for building construction while economically supplying insufficient natural history due to excessive collection work by sorting, sorting, and recycling.

In general, when buildings such as old houses or buildings are dismantled or demolished, construction wastes of various materials such as concrete, aggregate, reinforcing bars, other metal materials, gravel, wood, paper, glass, or plastics such as Styrofoam are generated in large quantities. Building wastes are classified as special wastes and are landfilled. Because the treatment area is limited due to environmental pollution, it takes a lot of time and effort to process industrial waste. Also, expensive landfill costs are required, which causes illegal dumping. There are many problems such as causing serious environmental pollution.

In addition, in terms of resource recycling, recyclable materials such as rebar, gravel, and sand are treated (landfilled) as they are, resulting in a huge waste of resources.

In order to solve the problems of the treatment (landfill) and recycling of the building waste as described above, a facility for separating and recycling various wastes mixed with the building waste has been developed for a long time.

However, the detailed equipment of the building waste recycling facility has continued to develop through technological development, but the recycling treatment cost increases because a treatment process for effective recycling by using the detailed equipment rationally cannot be prepared. There is a problem in that consumers and producers avoid recycling of construction waste because high-quality recycled products cannot be obtained because the separation of waste materials is not performed properly.

In addition, the conventional treatment process of the building waste recycling facility cannot remove or separate the dust and soil generated when building waste is put into the supply hopper, and the wet dust and foreign matter removal process causes water pollution and foreign substances that are not injured. is impossible to remove, and the increase in facility cost due to the installation of several crushing devices and the lack of a treatment process for dust generation causes civil complaints in neighboring areas. And there is a problem in that the installation area is excessive.

In addition, in the foreign material removal device applied to the conventional building waste recycling facility, there is a technical means to remove foreign substances with a low specific gravity with the air blowing force of the blower, but since the blowing force is weak or the foreign substances are transferred in a state containing the waste, it is possible to separate and collect them evenly. It was difficult to remove foreign substances with low specific gravity.
