The present invention relates to a construction waste sorting and recycling apparatus, and more particularly, it is possible to sort the construction waste by particle size using a single fan-type vibrating screen, and shred out construction waste immediately on site during the process of sorting construction waste. The present invention relates to a construction waste sorting and recycling device capable of producing recycled aggregates.

Types of waste that are inseparable due to working conditions such as waste cones, waste ascons, waste wood, rebars, earth and sand and other redevelopment sites at construction sites, namely construction wastes, vinyl waste, and household wastes, are generated annually. It is reaching 40 million tons. In order to recycle these wastes, the wastewater must be sorted by pretreatment, but more than 90% of the wastes are filled. Recycling performance in high value-added areas that are only used for landfilling is very poor.

Recently, technology for screening construction waste has been proposed in recognition of the seriousness of resource recycling and environmental pollution.

Construction waste sorting and recycling apparatus according to the prior art, for example, consists of a hopper to which the waste is injected and a sorting device for sorting the waste put into the hopper. The sorting device has a plurality of sorting holes, and there is a trommel for sorting the waste put into the size by rotating, a magnet for sorting the iron out of the waste by magnetic force, a blower for sorting the waste by the wind.

However, the construction waste sorting and recycling apparatus according to the prior art has the following problems.

Conventional trommel is a single structure formed in a circular plate formed by a plurality of screening holes, and sorts the construction waste according to the size of the screening hole, because it is a single structure waste remains in two kinds (ie, inside the trommel) Waste of size and waste of size that is discharged to the outside of Trommel).

Since trommels are thin plates, they can be damaged by heavy construction waste and block the sorting holes, and the spacing between the sorting holes should be large enough to prevent the trommel from tearing. There is a disadvantage that construction waste is stuck and clogged, there is a disadvantage that the work is cumbersome and does not solve the clogging cleanly as the worker relieves the retinal by applying a flame or knocking with a hammer by hand.

In order to solve this drawback, the applicant has applied for and registered a dual screen net trommel and construction waste sorting and recycling device having the same as the Patent No. 441430, and the construction waste sorting and recycling device having the fan-shaped vibrating screen as the Utility No. 39542. have.

However, the technology filed by the applicant has the following problems.

The fan-shaped vibrating screen sorts waste by particle size through the spacing between spokes, and since the spacing between the spokes is invariant, there is a disadvantage in that it cannot sort waste of various particle sizes. There is a disadvantage that the fan-shaped vibration screen having different intervals has to be detached according to the particle size of the waste.

And, the fall speed of the waste depends on the angle of the spoke and the weight of the spoke of the flat screen vibration screen. In other words, if the weight of the waste is heavy, the dropping speed of the waste is high, causing a breakage of the conveying conveyor. To this end, the angle of the spoke of the flat fan type vibration screen must be varied according to the weight of the flat waste. Since the angle also does not change, there is a disadvantage that the conveying conveyor is broken by the falling of the waste, also, to solve this disadvantage, there is a problem that must use a fan-shaped vibration screen having spokes of different angles.

In addition, according to the prior art described above, the waste is sorted by supplying to the trommel via a fan-shaped vibration screen, the waste of the particle size passed through the fan-shaped vibration screen is produced as recycled aggregate through a separate process (crushing, etc.). However, as the crushing process is separated from the above-described sorting process, it requires a person and equipment for transporting the waste that passed through the fan-type vibrating screen, and there is a problem in that time loss occurs due to transportation. .

An object of the present invention is to provide a construction waste sorting and recycling apparatus capable of producing circulating aggregates of various particle sizes using a single device.

In addition, another object of the present invention is to be able to produce a circulating aggregate by crushing immediately in the field during the selection process of construction waste.

Construction waste sorting and recycling apparatus according to the present invention provided to achieve the above object is installed between the feeder and the trommel and comprises a fan-type vibration screen for sorting the construction waste by size (by type), the fan The type vibration screen is characterized in that the plurality of spokes are separated and coupled to adjust the spacing.

The spokes may be connected to the spoke holders in an adjustable angle.
