Description

Device for reducing foreign substances in coarse aggregates by applying blowing and suction}

The present invention relates to a device for reducing foreign matter in coarse aggregate by applying blowing and suction, and more specifically, by applying blowing and suction, foreign matter mixed in coarse aggregate, particularly waste vinyl, paper, cloth, waste plastic, Styrofoam or waste It relates to a foreign matter reduction device for coarse aggregates using blowing and suction that separates and collects combustible foreign matter such as wood and induces discharge.

In order to be environmentally friendly and to recycle resources, wastes generated during construction or demolition of building structures are not landfilled, but are collected in a designated place, followed by a crushing process, a foreign matter sorting process, an aggregate and mortar separation process, and mortar attached to the surface of the aggregate. It is being produced as a high-quality resource through a series of intermediate treatment processes such as the peeling process.

Here, among the foreign substances mixed in the aggregate, metal materials are attached and removed by the electromagnetic magnetic machine, so there is no particular problem in sorting and removing them, but relatively low specific gravity such as waste vinyl, paper, pieces of cloth, waste plastic, Styrofoam or waste wood In the case of combustible foreign substances, since they had to be manually checked and removed manually, the selection and removal work was not only inconvenient, but also took a lot of time.

As a conventional method for selecting and removing combustible foreign substances having such a low specific gravity, a selective removal method using a water tank and a selective removal method using wind power have been proposed.

As such, in the conventional sorting and removal method using a water tank, a conveyor carrying construction or construction waste passes through the water of an aeration tank installed so that foreign substances mixed in construction or construction waste float to the surface of the water, and then a separate collection device As a method of sorting and removing foreign substances using a method, there is an advantage that dust is not scattered during the sorting process of foreign substances, but there is a problem against the eco-friendly aspect because the conveyor pollutes the water in the tank while passing through the water. However, as the conveyor passes through the water, it corrodes and the durability is weakened, and a separate drying device for drying the collected foreign substances is required, which increases the installation cost for providing the facilities.

In addition, in the conventional sorting and removal method using wind power, when wind power is supplied from the side of a conveyor carrying construction or construction waste, foreign substances mixed in construction or construction waste are separated and removed from the side of the conveyor, and sorted and removed using a water tank. Although it has the advantage of being eco-friendly because it does not pollute water compared to the method, there is a problem in that the sorting efficiency is lowered because it is difficult to sort and remove foreign substances embedded in or pressed down by the wind.
