The present invention relates to a construction waste sorting apparatus, and specifically, wood or gloves wetted by water, which are not removed by a blower, are transferred to a vibrating sorter using a turbo blower having a strong blowing force, and combustible foreign matter and The present invention relates to a construction waste sorting device that facilitates the removal of flammable contaminants for screening aggregates and collecting fine powder through nonwoven fabrics.

According to the so-called development priority policy and high-growth policy promotion, it has been a reality that the adverse environmental problem in Korea has been somewhat out of consideration.

However, as a result of this growth-oriented policy, the growth of various wastes and pollutants in the by-products has reached an urgent point which can no longer be delayed.

In particular, the construction industry wastes of various constructions and civil works show a sharp increase, mainly due to the recent redevelopment, activation of reconstruction and dismantling of structures due to aging and deterioration of urban and local buildings. do.

In general, construction waste refers to soil, sand, gravel, earth or mixed soil mixed with rubbish and waste materials, concrete lumps, waste wood, asphalt concrete lumps, and construction sludge. One of the main characteristics is that most of the construction wastes are composed of inorganic materials, which are harmless to the human body, and that various kinds of wastes are discharged in a mixed state, and their treatment is complicated and difficult. It is said to provide the cause of indifference between the government and industry regarding waste disposal.

Such indifference entailed a waste of valuable resources, and caused the deterioration of the quality of recycled aggregates, and most of the utilization of recycled aggregates was only used for earthworks, such as fill, cover, and landfill.

Therefore, by realizing the recycling through the management of such wastes, it is necessary to actively minimize the environmental pollution, replace the scarce resources, and reduce the cost of the construction industry base.

To this end, the Law on the Promotion of Saving and Recycling of Resources has recently been enacted in Korea, and the recycling of construction waste has become mandatory, and various production facilities for recycling have been produced and applied to various industrial sites.

Construction waste recycling apparatus according to the prior art, one or more shredders (such as jaw crusher, hammer crusher) for crushing the construction waste, magnetic sorter for sorting iron lumps contained in the construction waste, cleaning means for cleaning the crushed aggregate, aggregate Screening screen in the form of a net to sort according to the size, consisting of a conveying means (for example, a conveyor) for transporting the construction waste (aggregate) by connecting the respective devices.

Construction waste sorting technology according to the prior art has a plurality of screening screens for screening the aggregate (crushed soil, flammable foreign matter, fine powder) by the crusher by size / type (aggregate, soil, flammable foreign matter, fine powder), Install a conveying conveyor on a large site to pass aggregate through the screening screen to sort it into aggregate and soil, and transfer the aggregated and soil selected through the conveying conveyor to another screening screen, and then combustible foreign substances contained in the aggregate and soil. (Combustible waste) is screened, and the fines are screened through another screen.

Therefore, the construction waste sorting technology according to the prior art does not sort aggregates, earth and sand, combustible foreign substances, and fines in one process, but sorts them through various processes. There are problems such as a lot of labor costs for.

On the other hand, in the prior art, a specific gravity sorting device for sorting waste materials having low specific gravity (soil, styrofoam, paper, wood, etc.) by blowing power may be installed. However, the specific gravity sorting device is installed at any one of the construction waste transport paths to sort wastes having a low specific gravity while the construction waste falls. Small flammable debris is included, resulting in poor aggregate quality. In order to prevent this, the specific gravity sorting device may be installed in several places to sort out waste having a small specific gravity, but this increases the installation and maintenance costs and complicates the recycling facility.

In addition, the construction waste intermediate treatment company according to the prior art is to transport the construction waste removed from the building demolition site to the intermediate treatment site for the recycling process. Therefore, in reality, most of the intermediate processing costs are consumed as transportation costs, and there is a problem in that the added value is lowered. In addition, since the intermediate processing companies only perform intermediate processing in a nearby area to minimize transportation costs, there is also a problem in that the profit structure is very narrow.

In order to solve this problem, the applicant has developed patent registration 0587023 (crushed construction waste sorting device).

The shredded construction waste sorting apparatus is shredded more than one time by a shredder (cone crusher, hammer crusher, etc.) as shown in FIGS. 1 and 2 and the prefabricated construction waste such as iron lumps are sorted through a magnetic separator. By sorting by type and receiving pretreated construction waste (aggregate, soil, combustible foreign matter (waste vinyl, waste styrofoam, waste wood, etc.) and fine powder mixed) from fork crane, conveying conveyor, etc. The sorting tank 10 and the blower 20 for sorting the construction waste supplied to the sorting tank 10 by type (aggregate, earth and sand (including flammable foreign matter), and fine powder) by the specific gravity difference, and the sorting tank 10). ) By vibrating the earth and sand (including flammable foreign matter) to be discharged from the screen is composed of a vibration sorter (30) for sorting the earth and sand and the combustible foreign matter.

(P) is composed of a differential discharge port 15 is discharged.

When the fine powder P is discharged by the blowing force of the blower 20, the sorting net 16 is further installed at the inlet side of the fine powder outlet 15 so that flammable foreign substances having a light specific gravity are not discharged together.

The duct 17 may be installed so that the fine powder P discharged through the fine powder outlet 15 may be collected without being scattered widely.

Since some of the construction wastes introduced through the hopper 12 may stick to each other and may not be sorted by the blowing force, the construction wastes injected into the hopper 12 may fall from each other in a fixed state before passing through the blower 20. The vibration feeder may be further installed at the inlet side of the hopper 12 so as to be provided.

The sorting tank 10 of such a structure may be deformed and damaged while the aggregate is collided as construction wastes such as aggregates are injected. Thus, a double structure may be made of steel having a high strength or a replaceable plate is padded on the inner wall to minimize this. have.

The blower 20 is installed on one side wall (directly below the hopper 12) of the main body 11 of the sorting tank 10 so that the blowing force is lowered from one side (the right side of FIG. 1) of the hopper 12 (FIG. 1). Construction waste generated through the hopper 12 by the left side of the reference is selected by aggregate (A), earth and sand (S) (including flammable foreign matter (W)), fine (P).

Although not shown in the drawings, the blower 20 operates by receiving power through a power cable, and is fixed to the sorting tank 10 through an angle 18, and the blower 21 of one side is inside the sorting tank 10. Coupled to communicate with.

A plurality of blowers 20 may be mounted in a line up and down to generate a blowing force, and in this case, the plurality of blowers 20 may generate the same blowing force or generate a different blowing force.

The vibrating screen 33 is a two-stage structure in which the foreign matter discharge net 33a and the soil discharge plate 33b are stacked.

The earth and sand (S) and the combustible foreign matter (W) sorted by the vibration sorter 30 may be stacked on the sorting site or transferred through the transfer conveyor 34 and then loaded in the loading box (35).

When the earth and sand (S) and the combustible foreign matter (W) falls from the earth and sand outlet 14 of the sorting tank 10 to the vibrating screen 33 of the vibrating separator 30, the earth and sand outlets 14 and Between the vibrating screens 33 is closed via the duct 36.

However, the shredded construction waste sorting device has a problem in that water or wet wood or gloves are not removed from the blower of the blower in the process of removing flammable foreign matter through a blower composed of multiple stages, and fall like aggregates.

In addition, the shredded construction waste sorting device has a problem of preventing dust from simply scattering through the duct without a separate dust collecting device, but the fine powder passing through the duct is scattered to the atmosphere as it is, causing air pollution.

The present invention is to solve the problems as described above, by using a turbo blower of a strong blowing force, such as wood or gloves wetted by water that was not removed by the blower to the vibrating sorter, flammable foreign matter and aggregate through the vibrating sorter It is an object of the present invention to provide a construction waste sorting device that can easily remove the combustible foreign matter by increasing the efficiency of removing the combustible foreign matter.
