Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described. The present invention has been described with reference to the embodiments shown in the drawings, which are described as one embodiment by which the technical spirit of the present invention and its core configuration and operation are not limited.

The construction waste (W) brought in from the demolition site of the building, or other construction waste generation site includes flammables, and in the present invention, such wood or other combustibles are selectively separated from the construction waste (W). Such combustibles can be broadly classified into wood and other combustibles other than wood (paper, textiles, plastics, vinyl, etc.), depending on their materials. Throughout this specification, including claims, wood is referred to as " One kind of combustible ", and other combustibles except wood, such as paper, textile, plastic, vinyl, synthetic resin, etc. are called" two kinds of combustibles ", and the said one combustible and two kinds of combustibles are called" combustibles " It is called.

Flammable sorting apparatus according to the present invention may be composed of only the flammable wet sorting device 20, in addition to the flammable wet sorting device 20 may be configured to further comprise a flammable specific gravity sorting device (30).

First, FIG. 1 and FIG. 2 are schematic side and perspective views showing the configuration of the combustible wet sorting device 20 provided in one embodiment of the combustible sorting and separating apparatus according to the present invention, respectively. In FIG. 2, the water level of the water contained in the water tank 21 is omitted for convenience.

Most kinds of combustibles such as wood and two kinds of combustibles such as paper have a characteristic that they float when they are put in water because their specific gravity is light. On the other hand, non-combustible materials such as aggregates, concrete crushed materials, metals, and glass sink in water due to their heavy specific gravity. In the combustible wet sorting device 20 according to the present invention, the combustible wet sorting step of collecting construction combustibles floating on water by inputting construction waste W into water is performed.

As shown in the figure, the combustible wet sorting apparatus 20 according to the present invention is a water tank 21 containing water, one side of the inclined lower side is inclined to the water in the water tank 21 and the other side is a water tank Transfer conveyor device installed in the water tank 21 so as to be out of the water of the water 21, and transfers the non-combustibles sinking into the water of the water tank 21 from the construction waste W introduced into the water tank 21 out of the water tank 21 ( 22) and a floating combustible collector 23 which collects the combustibles C floating on the water of the water tank 21 and separates them out of the water tank 21.

As shown in the figure, water is contained in the water tank 21, and the conveying conveyor device 22 is disposed in the water tank 21 in an inclined state, and the inclined lower portion of the conveying device 22 is a water tank. The submerged upper part of the tank 21 is immersed in the water 21 and is outside the water of the tank 21 so that its end portion is located outside the tank 21. In particular, in the present invention, the conveying chain 221 of the conveying conveyor device 22 is moved from the inclined upper portion toward the lower portion. One side of the water tank 21 in the inclined lower portion of the transfer conveyor device 22 is provided with a floating combustible collector 23 for collecting floating combustibles and discharging them to the outside of the water tank 21. As illustrated in the drawings, the floating combustible collector 23 may have a form in which a plurality of fans 231 rotate, and the combustibles C floating on the water surface of the water tank 21 while the fans 231 rotate. It is pumped out of the tank 21. However, in the present invention, the floating combustible collector 23 is not limited thereto.

On the other hand, in order to effectively remove the soil or fine material adhered to the surface of the construction waste introduced into the water tank 21, the micro bubble generator 24 for spraying bubbles toward the construction waste injected into the water tank 21 is the water tank 21 may be further provided. In order to help the combustibles floating on the water surface of the water tank 21 to move toward the floating combustible collector 23, the fine bubbles generated by the microbubble generator 24 are directed toward the floating combustible collector 23. It is preferable to install the micro bubble generator 24.

Looking at the operation relationship of the combustible wet sorting device 20 according to the present invention having the configuration as described above, as shown in the drawing, the construction waste (W) is put in the state in which the water tank 21 is filled with water. In the figure, the member number 13 is an input hole 13 through which construction waste is input. Construction waste conveyed by a conveying device such as a conveyor belt is introduced into the water tank 21 through the inlet 13. In the inputted construction waste (W), the combustibles are suspended in the water surface of the tank 21, non-combustibles such as heavy aggregates, steel, glass, etc. sink. The transfer chain 221 is configured to move from an inclined upper portion to a lower portion. As shown in the drawing, the transfer chain 221 is provided with a protruding drag member 222.

Non-combustibles from construction waste (W) introduced into the water tank 21 passes through the drag members 222 of the transfer chain 221 to fall on the inclined plate 26 or to the bottom 28 of the water tank 21. As the transfer chain 221 rotates, the drag member 222 scrapes the non-combustibles accumulated on the bottom 28 and the non-combustibles falling on the inclined plate 26 to be transported out of the water tank 21 to be discharged to the outside. do.

The inclined plate 26 is preferably configured to adjust the inclination of the inclined plate in accordance with the installation inclination of the transfer conveyor device 22 using the cylinder device 261 or the like. The transfer chain 221 may be in the form of a penetrating between the drag member 222, but may also be in the form of a belt. If the conveying chain 221 is formed in the form of a belt, the construction waste (W) dropped into the water tank 21 is continuously transferred to the depth of the water tank 21 as the belt rotates in a state of being placed on the belt, In the process, the combustibles remaining in the construction waste rise to the surface. On the other hand, the construction waste (W) collected on the bottom 28 may be removed by a separate suction device.

The flammables C floating on the water surface of the water tank 21 are collected and discharged by the floating flammable collector 23, and if the flammables are contained in water for a long time, they can absorb and sink in the process, thereby preventing them. In order to do this, the floating combustibles need to be moved quickly in the direction of the floating combustible collector 23. To this end, it is preferable to cause the water flow in the direction of the floating combustible collector 23 in the water tank 21. For example, the water flow may be generated by allowing water to flow into the water tank 21 at a position facing the floating combustible collector 23. In addition, as mentioned above, the microbubble generator 24 may be further installed to form the above water flow. That is, when the bubbles are ejected toward the floating combustible collector 23 through the micro bubble generator 24, the combustibles floating on the water surface of the water tank 21 naturally move toward the floating combustible collector 23. In addition to the water flow forming function as described above, the micro bubble generator 24 performs a function of surface sand removal and fine material removal of suspended combustibles through bubble generation.

Even if flammables are added to the water, fine materials such as soil and powders on the surface of the flammables may not be washed out. If soil or fine material is on the combustibles, the process of separating and classifying one kind of combustibles such as wood and the other two kinds of combustibles will adversely affect the accuracy of sorting one kind of combustibles and two kinds of combustibles. Can give Therefore, it is preferable to remove the soil or fine material on the surface of the flammable, if the bubble is generated by using the micro bubble generator 24 as described above, as a result effectively removes the soil or fine material on the surface of the flammable You can do it. Therefore, the combustible material from which the soil and the fine substance adhered to the surface through such a process is additionally classified into one kind of combustible material and two kinds of combustible material, and the sorting efficiency is very excellent. That is, not only to separate the combustibles from the construction waste (W), but also very effective in classifying the separated combustibles into one kind of combustibles and two kinds of combustibles.

On the other hand, if necessary, the pump device 25 is installed in the water tank 21 to artificially generate water flow in the direction of the floating combustible collector 23 so that the floating combustibles can easily move toward the floating combustible collector 23. It is also preferable. That is, it may be further provided with a pump device 25 for emitting water in the direction of the floating combustible collector 23.

The floating flammable collector 23 collects the flammable and upcoming flammables and discharges them to the outside of the water tank 21. In the embodiment shown in the drawing, the floating flammables collector 23 includes a plurality of rotating fans 231, and thus the fan 231 rotates. While floating the floating combustibles are discharged to the outside of the tank (21). It is preferable to install a dehydration screen 27 on the outside of the water tank 21 to remove water from the combustibles C discharged to the outside of the water tank 21 by the floating combustible collector 23. Reference numeral 29 is a collection 29 of the combustibles discharged.

In the combustible wet sorting device 20 according to the present invention, the water contained in the water tank 21 is preferably recycled. The process of purifying water in the water tank 21 can use a well-known process. In the case of using the dewatering screen 27, the water collected through the dewatering screen 27 is also preferably recycled.

As described above, a considerable amount of combustibles are selectively separated from the construction wastes in the construction wastes through the combustibles wet sorting step using the combustibles wet sorting device 20 according to the present invention. The remaining construction waste, which is separated by combustible matter is separated, may be transferred to a landfill and landfilled, and thus, the process according to the present invention may be carried out. It is in a significantly reduced state. Therefore, it is possible to reduce the construction waste (W) discarded in the landfill, and to effectively cope with the current situation lacking the landfill. In addition, it is possible to separate the combustibles contained in the construction waste and to extract useful recycling resources, thereby saving resources.

On the other hand, after performing the wet screening step of separating and separating the combustibles from the construction waste (W) through such a combustibles wet sorting device 20, one kind of combustibles and 2 from the combustibles using the combustible specific gravity sorting device 30 A specific gravity screening step of sorting species combustibles may be performed. Of course, two types of combustibles may also be included in the non-combustibles submerged in the water in the wet sorting device 20, and two kinds of combustibles may be selectively separated using the combustible specific gravity sorting device 30.

Specifically, FIG. 3 and FIG. 4 are schematic side and perspective views showing the configuration of the specific gravity screening apparatus 30 according to the present invention, respectively. The wood included in the combustibles sorted and separated from the construction waste (W), that is, the one kind of combustibles, has a higher specific gravity than the two combustibles such as paper, textile materials, or synthetic resin materials (for example, PET containers). . The specific gravity sorting step of the flammables is further performed by the specific gravity sorting apparatus 30 shown in FIGS. 3 and 4 by using the characteristics of the flammables.

Two kinds of combustibles, such as paper, fiber, or synthetic resin, are lighter in weight than one type of combustible composed of wood. Therefore, if the flammables are dropped into the inclined conveyor belt device while the conveyor belt device is inclined, and the air is pressurized and blown in the direction of the conveyor belt device, two kinds of flammable materials such as light weight fiber and paper are pressurized and supplied. The pressure of the air is pressed toward the belt surface of the conveyor belt device, and the relatively heavy type 1 flammable drops along the inclined surface of the inclined conveyor belt device. If two kinds of combustibles are collected by moving the belt of the conveyor belt device while two kinds of combustibles are pressurized, one kind of combustibles and two kinds of combustibles can be easily sorted.

As shown in the figure, the combustible specific gravity sorting apparatus 30 according to the present invention is a supply device 31 for supplying a combustible or construction waste is mixed two kinds of combustibles, and under the discharge end of the supply device 31 The inclined discharge conveyor belt device 32 which is installed inclined and moves upward, and the two kinds of lightweight combustibles by blowing air to the combustible or construction waste falling from the supply device 31 are the inclined discharge conveyor belt device 32. It comprises a pressurized blower 33 to be pressed to the belt surface of the. The supply device 31 may be configured as a conveyor belt device as illustrated in the drawings, but is not necessarily limited thereto.

In the combustible specific gravity sorting device 30 according to the present invention, when the combustibles C or construction waste falls from the discharge end of the supply device 31, the air is inclined discharge conveyor belt device from the pressurized blower 33. When pressurized and supplied in the direction of (32), two kinds of combustibles such as a fiber material and paper having a light specific gravity are pressed toward the belt surface of the inclined discharge conveyor belt device 32 by the pressure of the pressurized air. In the pressurized state, it is conveyed to the upper side together with the belt of the inclined discharge conveyor belt device 32 moving to the inclined upper portion. On the other hand, because the first kind of combustibles and non-combustibles made of wood have a high specific gravity and the inclined discharge conveyor belt device 32 is installed inclined, the inclined discharge conveyor belt due to its own weight despite the pressurized air from the pressurized blower 33. The belt surface of the device 32 is slid to fall in the downward direction of the inclined discharge conveyor belt device 32. Through this process, two kinds of combustibles are selected and separated from construction waste or combustibles. In the specific gravity sorting separator 30 according to the present invention as described above, the inclined discharge conveyor belt device 32 is preferably inclined at an angle of about 20 to 55 degrees with respect to the horizontal plane. If it is inclined to less than 20 degrees, one kind of combustibles are also pressed into the pressurized air and transferred to the upper side together with the belt of the inclined discharge conveyor belt device 32, so that it is difficult to separate one kind of combustibles and two kinds of combustibles. When inclined at an excessive angle, even if pressurized air of strong pressure is applied, the two kinds of combustibles also fall down the discharge conveyor belt device 32 due to its own weight so as not to be separated. Therefore, the inclination angle with respect to the horizontal plane of the inclined discharge conveyor belt device 32 is preferably in the range of about 20 to 55 degrees.

The inclined discharge conveyor belt device 32 may be configured so that its inclination can be adjusted, as shown in the figure to form a long hole on the side of the inclined discharge conveyor belt device 32, the support arm to move along the long hole It can be configured to make tilt adjustment possible. However, it is not limited thereto. In addition, the pressurized blower 33 may also be configured to allow the blower nozzle to be rotated on the mounting arm as illustrated in the drawing so that the blowing angle of the pressurized blower 33 can be adjusted. However, this is also illustrative and the configuration for changing the angle of the pressurized blower 33 is not limited thereto. In the drawings, reference numeral 34 denotes a flammable fly prevention net 34 installed as necessary to prevent two kinds of flammables from flying out.

As such, after performing the wet screening step, if the specific gravity screening step using the specific gravity screening device 30 is additionally performed, one kind of combustible material (wood) and two types having different uses and values from the combustibles extracted from construction waste It can be further classified as flammables (species, textiles or synthetic resins), further increasing the recycling of resources. In addition, even if the combustibles are removed by the wet sorting step, by performing the specific gravity sorting step using the specific gravity sorting device 30, two kinds of combustibles can be further separated and separated.

1 and 2 are a schematic side view and a perspective view showing the main configuration of the combustible wet sorting device provided in the combustible sorting separator according to the present invention, respectively.

3 and 4 are a schematic side view and a perspective view showing the configuration of a flammable specific gravity sorting apparatus provided in the flammable sorting separator according to the present invention, respectively.
