Building waste generally refers to a kind of waste building material that is produced when various buildings are demolished. It is a mixed state of rebar and cement blocks and gravel, paper, vinyl, wood chips, soil piles, and other wastes. It is ready.

Such construction wastes are usually buried in landfills such as reclamation sites through legal procedures, but are seriously polluted due to unauthorized dumping on general roadsides, trailing edges, or nearby vacant lands.

However, even if construction waste is legally buried in landfills, it cannot be a fundamental countermeasure against environmental pollution. The reason is that the landfill construction waste is mixed with reinforcing rods, cement lumps and stones, paper, wood chips, soil piles, as well as other non-corrosive substances such as vinyl or organic compounds such as plastics. Building wastes mixed with various pollutants are being landfilled without being separated, which leads to problems such as severe odor as well as severe pollution of the soil with time.

In addition, from the point of view of resource recycling, recyclable materials such as rebar and stone (gravel) are thrown away (buried), which causes enormous resource waste.

In order to solve these conventional problems comprehensively, Korean Utility Model Utility Model No. 1996-611 is provided with a conveyor for conveying construction waste, which is installed from the screen separator on the upper side of the water tank of the main body. In the configuration, a screen conveyor for filtering suspended solids in a predetermined position (on the water surface) of the water tank is configured to be installed in the transverse direction. The wall is provided with a blower having a downward inclination angle toward the front at a position slightly higher than the surface of the water, and a bucket conveyor is inclined upward from the rear lower portion of the water tank to the upper upper portion. Construction wastes supplied to the main body through a conveyor for conveying and supplying construction wastes are contained in the tank. Due to the water, the weight body (landfill object) is settled down and separated on a bucket conveyor, while the lighter weight suspended solids (incineration object) can be separated and separated by a screen conveyor for filtering the suspended solids. Disclosed is a wet sorting device for a construction waste sorting and separating system, characterized in that it is configured to

Korean Utility Model Model No. 1998-25251 discloses a wet sorting device for a construction waste sorting and separating system, and FIG. 1 and FIG. 2 show a schematic shape thereof. The above-mentioned utility model No. 1998-25251 is installed so that one side is opened inside the water tank 11, and the drums 2 including a plurality of equally spaced buckets 22 are installed in the circumferential direction on the inner periphery so as to be rotatable.

Figure 5 is a perspective view showing one embodiment in the present invention, elements, such as a motor, a bearing, a shaft, etc. are omitted except those necessary to understand the present invention. Also, the blower pipe 5, the discharge hole 51, the floating material blocking member 52, the blower 53, the suspended material filtering portion 6, the motor 61, and the shaft 62 shown in Figs. In the present invention, the parts commonly referred to as suspended material filtering portions are omitted. In addition, a conveyor may be additionally installed on one side of the suspended material filtering part 6 to load the suspended material at a desired position, or the suspended material may be removed by a conventional method.

In order to remove the suspended solids, the same as or similar to those in the related art, or a conventional suspended matter removing method may be used, and thus may be omitted by those skilled in the art.

Referring to Figure 5, the wet regenerated aggregate sorting apparatus according to the present invention,

The tank 100, the drum 110, the sludge discharge means 120, the screw 130, the suspended solids filter (not shown), the input unit 200, the discharge unit 300, the screen 400 is composed of .

The water tank 100 is a hopper type. The water tank 100 may be configured as shown in the figure, but may also be configured as an inverted pyramid type. When the reverse pyramid type is configured, the screw 130 may not be necessary.

As the input part 200, the crushed building waste material or a material equivalent thereto is dropped into the drum 110. Here, the material equivalent thereto may be various mixtures such as gravel and sand, mud and vinyl, or by-mixed concrete by-products.

A bucket 112 is installed inside the drum 110, and a sorting hole 114 is drilled through the drum 110 and the bucket 112. The drum 110 is rotated by external power, and according to the rotation, the sorting hole 114 passes sand, mud, water, etc. smaller than the diameter of the sorting hole 114. Therefore, sand or mud having a smaller size than the diameter of the sorting hole 114 is accumulated in the lower part of the water tank 100. On the other hand, the water in the drum 110 is suspended in a material having a specific gravity less than the water contained in the crushed building materials, the suspended solids is suspended to the outside by a suspended material trap (not shown) installed inside the drum 110 Discharged.

The drum 110 may change the size of the sorting hole 114 to adjust the thickness of the regeneration sand or the thickness of the reclaimed sand, or may replace the drum to suggest various working conditions. In FIG. 5, the drum 110 is made of an iron plate or a plate equivalent thereto, but has a shape in which a selection hole 114 is drilled in the plate, but the plate may be made of a wire mesh. In addition, the drum 110 may be configured to vibrate to increase the efficiency of sorting.

In addition, the regenerators having a larger diameter than the sorting hole 114 lifted up by the bucket 112 fall to the discharge part 300 mounted inside the drum 110 and move outward along the discharge part 300. Discharged. The discharge unit 300 may be configured to vibrate or a conveyor belt in some cases, may be to remove the moisture attached to the regeneration gravel with a hole of 5 ~ 10mm in the bottom.

Screw 120 is continuously rotated in the lower portion of the water tank 100 to continuously move the sludge deposited in the lower portion of the water tank 100 in the direction of the sludge discharge means 120, the sludge discharge means 120 is periodically Or intermittently opened and closed to discharge the precipitated sludge. The sludge discharge means 120 takes into account any one or more of the input cycle of the crushed building material, the processing capacity of the screen 400, the amount of sludge deposited in the lower portion of the water tank 100, the load of the screw 130 It is preferable to open and close automatically.

The discharged sludge is introduced into the screen 400 installed separately or integrally under the water tank 100, and the screen 400 is separated into recycled sand and other materials (mud + water). The other material (mud + water) may be separated again using another screen, or the screen 400 may be made double.

The water tank 100 may be provided with an automatic water supply device for maintaining a constant water level. In addition, the mud of the other material collected through the screen 400 in the water collecting plant is precipitated, the supernatant water may be supplied to the water tank 100 by a conventional method.

The screen 400 may adjust the size of the mesh to adjust the thickness of the reclaimed sand, the screen 400 is preferably made of a vibration type.

In addition, the screen 400 may be replaced with another. For example, the water tank 100 and the drum 110 as described above may be installed and the size of the sorting hole 114 may be made smaller and replaced with the screen 400. In this case, it is preferable to configure the drum 110 with a wire mesh (mesh).

The above embodiment is only one invention for expressing the present invention, and the present invention is not limited to the above embodiment.

As described above, according to the present invention, a hopper-type tank and a sorting hole having a diameter of 5 to 50 mm are drilled on the circumferential surface and / or bucket of the drum immersed in the tank, and discharged through the sludge discharge means connected to the bottom of the tank. By installing the screen for screening the mixture, the installation area is small, the recycled gravel and the reclaimed sand can be easily sorted and recycled from the recycled aggregate, and the effect of suppressing the generation of dust in the screening process.
