The present invention relates to a recycled aggregate production system, and more particularly, to a recycled aggregate production system having a wind sorting device capable of sorting fine aggregates and foreign matter by wind power.

In recent years, the abuse of resources has reduced its reserves and the use of more stringent environmental standards has resulted in a number of restrictions on harvesting, leading to the production and supply of natural aggregates or building materials.

Almost the only alternative that can overcome this limitation of natural aggregate supply is to recycle the waste aggregate in the construction or civil waste from various demolition sites.

However, most of the waste aggregate generated in the construction site is large and its particle size is not uniform, it can be said that it is not suitable for use as the recycled aggregate for construction / construction.

Therefore, a processing operation for making such waste aggregates usable as aggregates or building materials must be performed. A general waste aggregate recycling system, as shown in FIG. The input hopper or the input conveyor (1), the conveyor belt (2) for guiding the injected waste aggregate (A) to the screen, and the waste aggregate (A) conveyed by the conveyor belt can be used as recycled aggregate as it is below a certain particle size. Screening (3) for sorting and collecting more than a predetermined particle size into a grinder, and a grinder (4) for crushing the waste aggregate (A) of a predetermined particle size or less from the screen into a recyclable particle by crushing using a crushing roller, etc. It is composed.

The conventional recycled aggregate production system configured as described above is processed into a granular aggregate of usable particle size by pulverizing a large lump with a grinder after the shipbuilding sorting the waste aggregate having a bulky and uneven particle size distribution by a screen.

On the other hand, the waste generated from the construction / construction site is mixed with a variety of foreign matter, the waste of this state is usually applied to the recycle aggregate production system after the impurities are filtered to some extent.

However, since the impurity sorting operation cannot be precisely performed due to the characteristics of raw materials and economic reasons, some amount of impurities are still mixed in the waste aggregate provided as a raw material to the recycled aggregate production system.

When impurities mixed with the waste aggregate pass through the screen or are crushed by the crusher and mixed into the final recycled aggregate, the quality of the aggregate is drastically deteriorated, and even if the use itself becomes difficult or used, there is a big limitation on the range of use. This results in deterioration of the quality of building / construction / civil works, and even creates safety problems.

As a method for solving the problem of impurity incorporation into recycled aggregates, the conventional method of using the floating method of removing the impurities by floating them in water.

However, the floating method has the advantage of producing the final recycled waste which is relatively high in processing efficiency and high quality, but it is necessary to reprocess wastewater as secondary waste generated after the waste treatment, and the cost of installing the treatment facility. This is not so economically desirable.

Such attempts to remove impurities from waste aggregates used in recycled aggregate production systems are often found in prior art in patents / utility models, for example, in Korean Patent Publication No. 2003-64185. In addition, there has been disclosed an attempt to remove impurities using a wind turbine by installing a rectangular blower having a diameter larger than that of the screen discharge port and providing a magnetic separator for removing the rebar and the like.

In addition, the Republic of Korea Patent Publication No. 2001-106385, between the screen and the conveying conveyor has a foreign matter removing means comprising a blower in an upward inclination type to upwardly blow, and having a foreign matter storage portion for accommodating foreign matter falling on the opposite side. Installed construction waste shredding and sorting systems have been disclosed.

However, these conventional wind-powered foreign matter removal systems have the advantages of simple installation of the device, simple design change and manufacture, and economical from the existing recycled aggregate production system, while small particle aggregates fly together with foreign matters. As a result, not only loss occurs in the aggregate, but aggregates are mixed in the foreign matter to be discarded, so that the disposal thereof is not easy.

Therefore, it can be said that the emergence of a recycling aggregate production system applied with a new foreign matter removing device that can produce high quality recycled waste, which can be said to be an advantage of the floating method, together with the economics of the foreign matter removing system using wind power.

The present invention has been made to solve the conventional problems as described above, the object is that the secondary waste, such as waste water does not occur when removing the foreign matter does not need to be treated again, small particle size blown with the foreign matter It is to provide a recycled aggregate production system that can recover the waste aggregate of the aggregate to prevent the loss of aggregate and facilitate the final disposal of foreign matter.

Another object of the present invention is to provide an economical recycled aggregate production system because the installation of the device for removing foreign matter is simple and can be easily applied to the existing recycled aggregate production system.

In addition, other objects, objects and advantages of the present invention will be described below, and will be appreciated by the embodiments of the present invention. Furthermore, the objects and advantages of the present invention can be realized by means and combinations indicated in the claims.

In the present invention, the grinder 40 is composed of one or more sets of engagement rollers 41, and any type or structure may be used as long as it can grind the waste aggregate to a desired size.

In addition, in the present invention, the blower 50 may be said to use a large output because of the characteristics of the waste aggregate, which is a relatively heavy material.

2 and 3, the blower pipe 60 of the recycle aggregate production system according to the first embodiment of the present invention has its own weight and particle size among the foreign substances introduced by the cylindrical body 61 and the blower 50. In order to re-separate the waste aggregate falling by the screening net 62 configured at the lower end of the body 61, the inlet opening is larger in diameter than the body 61 at the front end of the blower 50 direction of the body 61 ( 63), the foreign material discharge pipe 64 is formed at the rear end of the body 61, and the transfer pipe 65 for collecting the recycled aggregate discharged through the sorting network 62 is configured.

Here, the screening net 62 is provided at the lower end of the body 61 is used more dense than the net 31 provided in the screen 30, which is blown from the blower 50 with the foreign matter in the wind This is because blown waste aggregates are generally much smaller in size than waste aggregates sorted by direct screen 30.

In the blower pipe 60 of the recycle aggregate production system according to the first embodiment of the present invention configured as described above, a relatively light or large sized foreign material introduced by the blower 50 is not discharged through the sorting network 62. It floats and is discharged through the discharge pipe 64.

However, even if the size is small, the relatively dense waste aggregate falls by its own weight, and materials having a small particle size compared to the screen size of the sorting network 62 are separated as recycled aggregate through the transfer pipe 65. .
