Description

{Foreign Material Sorting System In Construction Waste By Striking-Vibration-Blowing-Suction Continuous Process}

The present invention is a blow-vibration-blowing-suction continuous process that effectively separates organic and inorganic foreign substances mixed in construction waste stones generated during the intermediate treatment process of construction wastes so that foreign substances can be recycled. It relates to a device for sorting foreign substances in construction waste soil.

Many structures, such as bridges, roads, and various structures that have arisen in the course of urbanization and industrialization have gradually become obsolete over the years, and recently, reconstruction and redevelopment are being promoted in many areas to improve residential culture.

In the process of dismantling or rebuilding and redeveloping these old structures, a lot of construction waste is generated. When such construction waste is landfilled, it is not only difficult to secure a landfill site, but also requires a lot of landfill cost and causes soil pollution. Various measures have been taken to recycle construction waste from two aspects of environmental protection and resource utilization, and various treatment devices for construction waste have been developed in Korea.

In accordance with the standards of the statute ^** , circulating soil separating foreign substances from construction waste soil ^* generated during the intermediate treatment process of construction waste is used for filling or reclaiming construction of approved construction works, 2) for landfill facilities For cover, 3) For soil improvement for farmland improvement ^{*** It} is about technology that can be recycled.

* Among constructions that are mixed with construction wastes during construction work, those that are separated, sorted, selected, soil, sand, gravel, or soils, sand, gravel, etc. generated during the intermediate treatment of construction wastes are excluded from natural ones (construction wastes) Enforcement Decree of the Recycling Promotion Act [Annex 1] No. 16)

** Article 4 (1) 3 of the Enforcement Decree of the Construction Waste Recycling Promotion Act

*** Enforcement Decree of the Farmland Act Article 3-2 2

Recycling soil must meet the quality standards set for each of the above purposes (currently announced by Ministry of Land, Infrastructure and Transport No. 2017-1711. 2017.12.15, all revised). Conditions for organic matter content of 1.0 vol% or less for both sex and cover are common. Must be met.

Conventional techniques for separating foreign substances from construction wastes are largely divided into wet and dry techniques.

Wet technology is a technique that puts wastewater and construction wastewater into a immersion tank and removes it with a small specific gravity floating on it. Patent Nos. 10-0756420 and 10-0588836 are examples of such wet technology.

The dry technology is composed of various means such as heating, centrifugation, and blowing.

However, the heating method of incineration by burning inflammable organic foreign matters is a problem of energy consumption and air pollution, and the treatment of wastewater is also a problem because a water treatment process for cooling the heated soil is required.

Centrifugal separation technology that allows specific gravity to be screened by centrifugal force has disadvantages in the continuous process, and the blowing technology that blows away small particles of specific gravity by blowing them away is separated only from the construction waste soil in which foreign matter is mixed. There is a disadvantage in that efficiency is poor because it is difficult to fly and separate.

On the other hand, Patent No. 10-1836832 is a technique for sucking and separating foreign matter with a relatively small specific gravity by providing suction power in a state in which construction wastes are scattered in a chamber by using means such as blow and blow. As the construction waste soil is scattered, only the foreign matter is sucked, so the separation efficiency of the foreign matter is improved compared to the conventional dry technologies, but when the suction power is provided evenly from the foreign matter and the waste soil evenly scattered in the chamber, a considerable amount of waste soil is sucked and discharged together. Occurred.

The present invention evenly spreads the construction waste soil in a coagulated state through blows and vibrations, and separates and sorts circulating soil and foreign substances through blowing and suction to increase the efficiency of sorting foreign substances, and selects foreign substances in construction waste stones that can be driven even in a specific function state. It is about the device.

First, terms used in the present specification are defined as follows.

1) Construction waste stone: Among soils generated from mixing with construction wastes during construction, soil, sand, gravel, etc. generated during the intermediate treatment of construction wastes are excluded from natural ones. that.

2) Foreign substances: Organic substances other than soil, sand and gravel contained in the construction waste soil. Styrofoam, plastic, vinyl, wood carving, paper, cloth, etc.

3) Circulating soil: Soil, sand, and gravel in the form of separating foreign substances from construction waste.

Hereinafter, the present invention will be described in detail with the accompanying drawings.

The present invention is a "rotating striking plate 30 installed to scatter and scatter in front of the falling construction waste stone; A vibration key (50) that receives scattered construction waste stone scattered by the striking plate (30) and applies vibration to discharge foreign substances in a specific gravity-selected state; A blower (60) for scattering foreign substances by supplying wind in an upward inclined direction to the construction waste soil discharged from the vibration key (50); A gravity discharge path 70 through which circulating soil other than foreign substances scattered by the blower 60 falls; A foreign matter chamber 80 for temporarily receiving and discharging foreign matter scattered by the blower 60; And a suction device 90 that provides suction force to the foreign matter chamber 80 with the foreign matter filter 92 therebetween; It provides a device for separating foreign substances in the construction waste soil by a continuous process of blow-vibration-blowing-suction.

As shown in [Fig. 1], the construction waste soil can be transported to the conveyor 10 and dropped on the supply chute 20, and in the present invention, the construction waste soil is aggregated and dropped through the supply chute 20. The rotating striking plate 30 is configured to scatter and scatter forward. Accordingly, the construction waste soil supplied in the aggregated state is scattered, which is advantageous for separating foreign substances.

The rotating striking plate 20 is arranged such that two discs having a concave front are partially overlapped, as shown in FIG. 2, and the driving force of the driving motor 31 is transmitted through the power transmission belt 33 as a medium. It can be configured to be transmitted to the drive shaft 32 provided at the center.

According to the rotational speed of the rotating striking plate 20 and the installation angle of the drive shaft 31, the angle and distance of the scattered construction waste stone can be adjusted, and the rotating striking plate ( 20) can be configured to adjust the rotation speed and the installation angle of the drive shaft 31.

As shown in [Fig. 3], in front of the rotating striking plate 30, a striking network 40 installed to scatter scattered construction waste soil may be installed.

As the striking network 40, a ridge network, a mesh network, or the like can be applied, and the process in which construction waste soil scattered forward by the rotating striking plate 20 hits the striking network 40 Construction waste soil aggregated in is scattered secondarily. All of the construction waste soil that has not penetrated or penetrated the striking network 40 is dropped down and supplied to the vibration key 50.

4 is a photograph taken by comparing construction waste soil before and after striking, that is, construction waste soil transferred to the conveyor 10 and construction waste soil that has passed through the rotating striking plate 30 and the striking net 40. . Before the blow, it was difficult to separate because the foreign matter was agglomerated on the soil, but after the blow, it was confirmed that the foreign matter was easily separated by simple manual operation.

The vibrating key 50 is a device that applies vibration to scattered and scattered construction waste and discharges it in a specific gravity screen. In the same way as separating key grains and gulp, the circulating soil and foreign matter of construction wastes are separated by specific gravity difference through vertical vibration.

The vibration key 50 is configured to be divided into upper and lower two stages, that is, the upper vibration key 50a and the lower vibration key 50b, as shown in [FIG. 5], and particle size selection for construction waste soil After specific gravity screening is performed, foreign material separation efficiency can be further improved.

The upper vibration key (50a) is to form a screen on the floor for the particle size selection of the construction waste soil, the construction waste soil that has passed through the screen is configured to be input to the lower vibration key (50b).

At this time, the construction waste stone that has passed through the screen may be configured to be input to the lower vibration key 50b through the lower supply path 51, wherein the upper end of the lower supply path 51 is the upper vibration key ( 50a) is coupled to cover the lower portion, and the lower end of the lower supply path 51 is coupled to cover the upper portion of the lower vibration key 50b, thereby causing the upper and lower vibration keys via the lower supply path 51 ( 50a, 50b) can be configured to form an integral (一体). In addition, the connecting plate 53 is applied to the side of the lower supply path 51 to combine the upper end of the connecting plate 53 with the upper vibration key 50a, and the lower end of the connecting plate 53. By combining with the lower vibration key (50b) it is possible to enhance the integrity of the upper and lower vibration keys (50a, 50b). In addition, by installing the vibrator 54 on the connecting plate 53, the upper and lower vibration keys 50a and 50b can be configured to vibrate together.

Meanwhile, without constructing a screen on the bottom of the bottom vibrating key 50b, all of the construction waste soil that has passed through the bottom screen of the top vibrating key 50a can be discharged toward the gravitational discharge path. Of course, by forming a screen having a small transmission diameter at the bottom of the lower vibration key 50b, residues (including residues) may be configured to be separated and discharged in advance through the residue discharge path 52 as shown in FIG. 5. have.

The blowing device 60 is a device that scatters foreign substances by supplying wind in an upward inclined direction to the construction waste soil discharged from the vibration key 50.

However, as described above, when the vibration key 50 is composed of two stages, upper and lower, as shown in [FIG. 6], the blower pipe 61 connected to the blower 60 is branched to the upper and lower sides. By configuring the lower vibration keys (50a, 50b) to be connected to the discharge portion, respectively, the upper and lower vibration keys (50a, 50b) can be separated from the foreign matter by blowing wind to each of the construction waste soil.

In addition, at the ends of the branched blower pipes 61, each of the upper and lower slits 62a, 62b can be configured to discharge wind by combining the blowers 62 having two slit in the horizontal direction. . Accordingly, the foreign matter that is not scattered by the wind discharged from the upper slit 62a can be scattered by the wind discharged from the lower slit 62b, thereby further enhancing the separation efficiency of foreign matter. In this case, since the inclination angle of the lower slit 62b is configured to be larger than the inclination angle of the upper slit 62a, foreign matter subjected to wind pressure at a relatively low position is scattered at a relatively high angle, and all of the scattered foreign matter are gravity discharge paths 70 ) From the side to the foreign material chamber 80 side so as not to be affected.

The gravity discharge path 70 corresponds to a path in which circulating soil other than foreign substances scattered by the blowing device 60 freely falls by gravity.

However, when the vibration key 50 is composed of two levels of upper and lower, foreign matter discharged from the lower vibration key 50a, which is discharged from the upper vibration key 50a and falls, may be impeded from scattering by wind. You can. Therefore, by installing the guide plate 71 inside the gravity discharge path 70, the falling path of the circulating soil discharged from the upper vibration key 50a is configured so as not to overlap with the blowing path on the discharge side of the lower vibration key 50b. can do.

Specifically, as shown in [Fig. 7], by installing the induction plate 71 of the "71" type on the upper part of the lower vibration key (50b) discharge side, the circular soil discharged from the upper vibration key (50a) The falling path of can be guided to both sides of the gravity discharge path 70, and thus the overlap of the falling path and the blowing path can be avoided.

The foreign matter chamber 80 is responsible for temporarily receiving and discharging foreign matter scattered by the blower 60. The gravity discharge path 70 and the foreign matter chamber 80 should be basically composed of separate spaces, but the path through which the foreign matter scatters by the blower 60 must be in communication.

The blower 60 supplies wind in one direction (from the gravity discharge path 70 side to the foreign matter chamber 80 side), and sucks the air inside the foreign matter chamber 80 from the suction device 90 to be described later. Therefore, the possibility of backflow from the foreign material chamber 80 side to the gravity discharge path 70 side is small. However, in order to remove the possibility that foreign matter floating in the foreign matter chamber 80 may pass to the gravity discharge path 70 side due to turbulence, a communication portion between the gravity discharge path 70 and the foreign matter chamber 80 The anti-wall plate 72 may be mounted thereon. The installation angle of the wall plate 72 may be adjusted according to the inclination angle of the wind supplied from the blower 60.

It is possible to prevent unnecessary dispersion of wind supplied from the blowing device 60 by installing an inclined plate 73 between the anti-vibration plate 72 on the discharge side of the lower vibration key 50b and the induction plate 71.

The suction device 90 provides a suction force to the foreign matter chamber 80 with the foreign matter filter 92 therebetween. In the suction device 90, air must be sucked in more than the amount of air supplied into the foreign matter chamber 80 so that the scattered foreign matter can flow into the foreign matter chamber 80 smoothly.

However, since the suction pipe 91 may be blocked when a foreign substance is sucked into the suction device 90, it is preferable that the foreign substance is directly discharged through the foreign substance discharge port 83 under the foreign substance chamber 80. Therefore, a foreign matter filter 92 for blocking foreign matter in the foreign matter chamber 80 from being sucked toward the suction pipe 91 should be provided.

Various means can be used as the foreign matter filter 92, but in the present invention, a waste net is filled in a box made of a metal mesh (ie, a regenerated mesh) to be applied as the foreign matter filter 92. You can. The foreign material filter 92 may be manufactured as a detachable type as shown in [FIG. 8] to replace and use a waste net as necessary.

On the other hand, the foreign matter chamber 80, but the bottom plate 82 as shown in [Fig. 1] and [Fig. 9] is coupled, the bottom plate 82 is hinged to rotate based on the axis of one side to the It can be configured to rotate downward due to the self-weight or periodic electrical signals of the foreign substances deposited on the bottom plate 82 to spill the foreign substances on the top. When the bottom plate 82 is rotated downward, it is possible to temporarily stop providing suction power from the suction device 90.

[Fig. 9] and [Fig. 10] show the paths and properties of substances that are introduced into and discharged from the apparatus of the present invention. Most of the circulating soil is discharged through the gravity discharge unit 70, and it is possible to discharge residues and residues through the above-described residue discharge path 52. All the foreign matter separated from the construction waste soil is discharged through the foreign material discharge port 83 opened downward in the foreign matter chamber 80.

In the present invention, the dust collecting device 100 for collecting and discharging dust from the air sucked through the foreign matter filter 92 may be further included. The dust collecting outlet 101 is also formed downward in the dust collecting device 100 to discharge dust that has flowed through the foreign matter filter 92 according to a predetermined time interval or dust collection amount.

In addition, by installing a circulating soil conveyor 110 at the lower portion of the gravity discharge path 70, the discharged circulating soil can be transported at a certain distance, and the circulating soil surrounding the falling circulating soil is covered at the lower end of the circulating soil conveyor 110. By installing the anti-vibration net 120, it is possible to prevent dust from scattering into the air.

However, if the distance between the bottom of the dustproof network 120 and the circulating soil file (dummy) is large, the scattering dust is not completely blocked. In the present invention, the dustproof network 120 is folded or unfolded according to the height of the circulating soil file. Together.

Specifically, a plurality of ring frames 121 are spaced apart and coupled to the inside or outside of the anti-vibration network 120, and the lifting line 122 is lowered from the top of the anti-vibration network 120, so that the plurality of ring frames 121 Penetrate through the bottom of the ring frame. The upper end of the lifting wire 122 is fixed to the electric reel 130, so that the lifting wire 122 is wound or released as the electric reel 130 rotates in the clockwise or counterclockwise direction to prevent the dustproof net ( 120) The bottom height can be adjusted.

In addition, at the bottom of the anti-vibration network 120, by mounting a distance sensor 140 capable of measuring the distance between the object and the object by means such as ultrasound, laser, the bottom of the anti-vibration network 120 measured by the distance sensor 140 And it can be configured to automatically control the driving of the electric reel 130 according to the distance of the top of the circular soil pile.

The present invention has been described in detail above along with specific examples. However, the present invention is not limited by the above embodiments, and can be modified and modified in a range without departing from the gist of the present invention. Therefore, the claims of the present invention include such modifications and variations.
