Description

Separation and recovery device for soil and aggregate of construction waste {APPARATUS FOR RECOVERING RECYCLED AGGREGATES FROM CONSTRUCTION WASTE}

The present invention relates to an apparatus for separating and recovering soil and aggregate of construction waste.

More specifically, construction waste is sprayed on an elastic plate provided in the lateral direction using the centrifugal force according to rotation, and the construction waste colliding with the elastic plate is It relates to an apparatus for separating and recovering soil and aggregates of construction waste, allowing them to be separated into aggregates.

In addition, the present invention freely falls the segregated material into soil and aggregate while bouncing off the elastic plate so that it can be finally separated, so that the aggregate having a large mass in the free fall will fall first compared to the soil and bounce away. Therefore, it relates to an apparatus for separating and recovering soil and aggregate of construction waste, which can prevent the aggregate from being separated by being contained in the soil and increase the recovery rate of the aggregate.

Construction waste generated in large quantities contains a large amount of soil and aggregate, and in particular, soil is recycled through sorting.

The soil that has undergone such a sorting operation includes residues such as aggregates that can be used as recycled aggregates, and if a detailed classification operation is followed, the recycling rate of construction waste can be further increased.

In the case of the existing sorting screen method, there is a problem that net clogging occurs depending on the moisture content of the soil and the separation efficiency of aggregate and soil is deteriorated. Therefore, the soil is usually separated using a 25mm~30mm sorting screen. It contains a large amount of recycled aggregate.

As a related technique, Korean Patent Publication No. 10-1136047 discloses an apparatus for separating and sorting foreign substances mixed in soil and aggregate.

The above technology is a technology related to a sorting device for separating and sorting soil by separating foreign substances from waste soils that are primarily selected from among waste wastes mixed with soil, combustible and non-combustible waste in an unsanitary landfill, circulation type landfill, or construction waste intermediate treatment plant. , After separating and sorting the waste soil mixed with combustible waste and various foreign substances with the primary sorting unit, the sorted waste soil is introduced into the inclined vibration chamber, and it is evenly spread and transported by reciprocating motion by swinging operation, while the transfer brush and rotating brush It mixes and spreads the transferred waste soil again, separates soil and foreign matter, falls into a vibrating chute, and separates combustible waste and foreign matter with a small specific gravity by applying air to the waste soil in the process of falling again evenly and falling through the vertical motion in the vibrating chute. On the other hand, in the inclined vibration chamber and the lower part of the vibrating chute, the intake port equipped with an electrostatic rod sucks and separates and sorts combustible waste and foreign matter with a light weight. , It relates to an apparatus for separating and sorting foreign matters mixed in soil and aggregates that treat waste soil environmentally by providing high-quality soil.

As described above, in the conventional screen method according to the moisture content of soil generated in the field, the higher the moisture content, the more the retina occurs, resulting in a problem that the separation efficiency of soil and aggregate is low.

In addition, separation using rotation is also being performed.

As a related technique, Korean Patent Application Publication No. 10-2116386 discloses a device for separating foreign substances in construction waste soil and aggregates by gravity using centrifugal force.

The above technology is a device for separating foreign substances from aggregates of building waste, comprising: a main body 10 having an input hopper 11 and a collection hopper 13; A striking means (20) installed adjacent to the input hopper (11) in the main body (10) and applying an impact force to the input aggregate; A suction means (30) for suctioning foreign substances by vacuum pressure by connecting a blower (36) to the suction cylinder (31) disposed below the striking means (20); A discharging means 40 for guiding and discharging the foreign matter sucked from the suction container 31 to the cyclone 42; And a control means 50 for controlling the striking means 20, the suction means 30, and the discharge means 40 with a set algorithm.

However, even in separating by using centrifugal force, there is a problem that the separation according to the mass of aggregate and soil in construction waste is not suitable.

In order to improve this, the applicant of the present invention intends to propose the present invention, and through this, when the soil is sprayed on an elastic plate having elasticity using a rotating body that rotates by centrifugal force, the aggregate with a large mass goes away, and on the contrary, the soil with a small mass Falls near the elastic plate, and by using this difference in weight of recycled aggregate and soil, it is possible to separate and sort even small aggregates due to their mass and size, thereby preventing aggregates from going out to soil and increasing the recycling rate of aggregates. Is expected.

In order to achieve the above-described object, the sediment and collection device for sediment and aggregate of construction waste according to the present invention discharges the input construction waste to an elastic plate by centrifugal force through a rotating means in the device, and is discharged to the elastic plate and bounced off. It is characterized by separating the aggregate from the soil by using a mass difference between the aggregate and soil contained in the original construction waste, and by providing a discharge means at a location corresponding to the distance from which the aggregate having a relatively large mass compared to the soil is bounced. .

In addition, it is characterized in that the earth and sand bounced from the elastic plate 40 fall into the space between the aggregate discharge port 50 and the inner surface of the elastic plate 40.

In addition, since the mass of the aggregate falling in the aggregate discharge port 50 is relatively larger than that of the soil, the falling speed of the aggregate is faster than that of the soil, so that the aggregate is mixed with the soil and is not separated.

Hereinafter, prior to the description with reference to the drawings, matters that are not necessary to reveal the gist of the present invention, that is, known configurations that can be obviously added by those skilled in the art are not shown or specifically described. Make the note clear.

The present invention relates to an apparatus for separating and recovering soil and aggregate of construction waste.

More specifically, construction waste is sprayed on an elastic plate provided in the lateral direction using the centrifugal force according to rotation, and the construction waste colliding with the elastic plate is It relates to an apparatus for separating and recovering soil and aggregates of construction waste, allowing them to be separated into aggregates.

In addition, the present invention freely falls the segregated material into soil and aggregate while bouncing off the elastic plate so that it can be finally separated, so that the aggregate having a large mass in the free fall will fall first compared to the soil and bounce away. Therefore, it relates to an apparatus for separating and recovering soil and aggregate of construction waste, which can prevent the aggregate from being separated by being contained in the soil and increase the recovery rate of the aggregate.

Figure 1 shows the separating and collecting apparatus for sediment and aggregate of construction waste according to the present invention.

The present invention according to Figure 1 of the accompanying drawings, the inlet 10; Upper plate 20; Rotor 30; Elastic plate 40; And the aggregate outlet 50; is configured to include.

The inlet 10 functions to inject construction waste into the device.

Outside of the inlet 10, although not shown in the drawing, a separate conveyor belt may be configured to transport construction waste to the inlet, and construction waste can be fed using construction equipment such as an excavator or a loader. It can also be a pouring method.

The inlet 10 includes an input area 11 having a cylindrical shape and a through hole through which construction waste can pass; And a coupling region 12 protruding from a lower end of the input region 11 to increase a diameter to form a stepped portion.

The upper plate 20 is located under the inlet 10 and is configured to be coupled to the coupling region 12 of the inlet 10. In addition, the upper plate 20 may include a hole 21 corresponding to the input area 11.

At this time, the bonding may be in the form of adhesion or attachment, but may be fastening through bolting.

The rotor 30 is located on the lower surface of the upper plate 20 and rotates, and has a structure in which a groove is formed downward from the upper surface in a cylindrical structure, and one side wall of the wall surface is opened due to the formation of the groove. It is composed of a structure having a shape.

Accordingly, the rotor 30 includes a discharge port 31 that is an open area, and includes a wedge 32 protruding upward from the bottom surface due to the concave groove.

In addition, the rotor 30 may further include a rotor 33, which is a structure for achieving rotation through conduction of voltage pulses, and the rotation of the rotor 30 is ① rotation using conduction of voltage pulses. , ② motor coupling within the applicable range of the skilled person (eg, coupling a motor to the top or bottom of the rotation shaft of the rotor 30), ③ rotation using magnetic force, etc. can be variously implemented.

However, in the present invention, it is sufficient if rotation is generated in the rotor 30 to generate more than a certain torque, and a centrifugal force is generated accordingly to achieve the scattering of construction waste in the circumferential direction.

In addition, the rotor 30 may be coupled so that an axis serving as a rotation axis of the rotor 30 extends in the vertical direction by penetrating from the center of the wedge 32 to the bottom surface of the concave groove.

This axis may be extended upward, downward, or upward and downward. In this case, it may be exposed to the lower side of the aggregate discharge port 50 to be described later, or may be exposed to the upper side of the inlet port 10.

Alternatively, a wall surface may be formed on the periphery of the device, and the shaft may be rotatably coupled to the wall surface.

The elastic plate 40 is a structure coupled to the lower surface of the upper plate 20 along the circumferential direction, and has a cylindrical shape having a penetrating structure in the vertical direction.

At this time, the entire inner wall surface or sidewall of the elastic plate 40 may be formed of an elastic material, and examples of the material include rubber, silicone, and the like.

The aggregate discharge port 50 is configured in a position adjacent to the lower side of the elastic plate 40, or at a position such that a part of the upper side is accommodated in the elastic plate 40, and the cone shape of the upper gwang haehyup having a slope that becomes narrower toward the lower side Can be configured to have.

Unlike the drawing, the aggregate outlet 50 may be configured to extend downward in a straight line to be supported from the ground, or the aggregate outlet 50 using a separate skeleton (frame) from the inner surface of the elastic plate 40 It may be implemented to be coupled to the elastic plate 40 by connecting a plurality of upper portions of the.

However, by adopting both configurations, the device is supported from the ground, and the aggregate outlet 50 may be fixed to the elastic plate 40.

Hereinafter, an operation example using the sediment and aggregate separation and recovery device of construction waste according to the present invention will be described through FIGS. 2 and 3 of the accompanying drawings.

FIG. 2 shows an example in which soil is separated using the sediment and aggregate separation and collection device of construction waste of FIG. 1, and FIG. 3 is an aggregate separation using the sediment and aggregate separation and collection device of the construction waste of FIG. It shows an example of being done.

However, although FIG. 2 and FIG. 3 are shown separately, it will be understood by those of ordinary skill in the art that separation of soil and aggregate is performed at once for construction waste in the apparatus.

First, when the construction waste injected through the inlet 10 is driven to the circumferential edge of the rotor 30 by centrifugal force by the rotation of the rotor 30, and is located around the discharge port 31 of the rotor 30 , Scattered through the discharge port 31.

At this time, in the case of including the rotor 33 in the rotor 30, by providing one or more through holes on one side of the rotor 33 as shown in the drawing, construction waste passes through the rotor 33 and the discharge port ( 31).

In this way, while the construction waste scattered through the discharge port 31 collides with the elastic plate 40, the soil and aggregate contained in the construction waste are bounced off by a distance corresponding to each mass.

For example, as shown in FIG. 2, since the mass of the soil is smaller than that of the aggregate, the distance to be bounced after collision with the elastic plate 40 will be less, and in the case of the aggregate as shown in FIG. 3, since the mass is larger than that of the soil, the elastic plate 40 The distance that will be bounced after collision will be longer than that of soil.

At this time, the diameter of the upper side having a large diameter of the aggregate discharge port 50 described above is formed to correspond to the bouncing distance of the aggregate.

That is, the aggregate outlet 50 is configured to have a diameter corresponding to the mass by checking the mass of the aggregate contained in the construction waste that is input in advance.

Therefore, the aggregate discharge port 50 may be provided with a plurality to fit a variety of diameters, may be manufactured and used according to the situation.

Accordingly, the aggregate bounced off by the elastic plate 40 will fall through the aggregate outlet 50, and the soil is not adjacent to the aggregate outlet 50, the aggregate outlet 50 and the elastic plate 40 It will fall into the space between the insides.

In this case, by providing a separate aggregate sorting box or the like under the aggregate discharge port 50, it is possible to separate the aggregate and the soil.

What has been described with reference to the drawings above is a description of only the main matters of the present invention, and it is obvious that the present invention is not limited to the configuration of the drawings as various designs are possible within the technical scope.
