Description

Rotary separation net adsorption separator for separating foreign substances in aggregate}

The present invention relates to a sorting device that removes lightweight foreign substances such as paper, wood chips, plastic pieces, vinyl, and Styrofoam in the process of intermediate processing of construction waste to produce recycled aggregate.

According to the National Waste Generation and Disposal Status Report (2019, Ministry of Environment, Korea Environment Corporation), construction waste accounts for 48.1% of all waste, and the amount of construction waste generated was 206,951 tons/day in 2018, a 5.4% increase from the previous year's 196,262 tons/day. did. Accordingly, the Ministry of Environment issued the “Notice on the Use and Mandatory Amount of Recycled Aggregate Recycled Products (2017, Ministry of Environment)”, which stipulates that the national, local governments, public institutions, etc. place orders for recycled aggregate that can be selected and recycled from construction waste. Mandatory use was stipulated for construction work.

However, despite recent efforts to sort and dismantle waste concrete, sorting combustible waste such as waste wood, waste plastic, and waste vinyl from waste concrete still remains an unresolved problem. Therefore, currently, lightweight foreign substances contained in waste concrete are removed through methods such as human screening, wind screening, and wet sorting before and after the first and second crushing processes for waste concrete.

However, combustible waste that is not sorted due to problems such as lack of manpower, lack of blowing pressure during wind power selection, and precipitation due to moisture adsorption is re-injected into the repeated crushing and grinding processes of the 3rd and 4th crushing processes to be crushed into smaller pieces. This eventually becomes mixed with small foreign substances in the recycled aggregate, causing problems such as instability in the quality of the recycled aggregate and reduced productivity.

As a method of separating and screening small foreign substances, wet screening is used to separate foreign substances floating on water using washing water, but there is a problem in that a large amount of wastewater and sludge is generated, causing soil and water pollution. Additionally, in winter, the washing water freezes, making it difficult to separate and sort out foreign substances, which limits the operation of the equipment all year round.

On the other hand, wind sorting using wind is a method of separating and sorting combustible waste contained in recycled aggregate by using the weight difference of foreign substances by generating wind from a blower. In relation to this, there are a number of research cases on wind power selection methods using cyclones. However, the cyclone method described above has the problem that aggregates with low specific gravity may be separated together with foreign substances and fine dust may scatter due to blowing. To solve these problems, research is being conducted on closed-type multi-stage blowing methods, but due to the difficulty in miniaturizing the equipment, it cannot be applied to the existing recycled aggregate sorting process.

Patent No. 10-2029736, “Vibration-suction sorting device for foreign substances in aggregate,” is “a device that sends aggregate supplied to a slope downward, and is equipped with a vibration supply means that causes up and down vibration, so that the aggregate is moved through the aggregate by vibration.” A vibrating sorting feeder that allows foreign substances to be discharged in a separated state by the difference in specific gravity; A conveyor belt that receives the aggregate discharged from the vibrating sorting feeder and transports it in one direction; A suction device installed above the point where aggregate is discharged from the vibrating sorting feeder and providing suction force introduced through a suction pump; and a screen belt installed along a track formed around the suction device and running in a direction opposite to the transport direction of the conveyor belt. It includes, and the suction force provided by the suction device is applied to the foreign matter in the discharged aggregate through the screen belt, so that the foreign matter is adsorbed on the screen belt and is configured to be transported and discharged in a direction opposite to the transfer direction of the aggregate. Provides a “vibration-suction screening device for foreign substances.”

Patent No. 10-2029736 as described above can efficiently separate lightweight foreign substances of various types and properties from aggregates by constructing a simple device to provide vibration and suction power.

However, as the screen belt continued to move along the circular track formed around the suction device, it was tilted in one direction, causing a problem in which the device had to be stopped and the position of the screen belt had to be readjusted. [Reference Photo 1] below is the pilot device of Patent No. 10-2029736, and [Reference Photo 2] is a photo taken with the screen belt tilted to one side.

In addition, a power transmission structure is needed to smoothly convert the rotational force generated by the electric motor into a force that circulates the screen belt in an endless orbit.

In order to separate and screen foreign substances, it is primarily important to adsorb foreign substances to the screen belt, but it is also important to ensure smooth discharge of foreign substances by eliminating the adsorption condition at an appropriate location, so an inlet structure is necessary to control suction power.

The screen belt can be configured to combine a plurality of connecting rods at equal intervals between chains on both sides, and a separation net made by weaving metal threads to tie the connecting rods.

On the outer surface of the separation net, a plurality of curtain nets, the upper end of which is installed in the width direction of the separation net and the lower end of which is configured not to contact the conveyor belt, may be arranged and combined at equal intervals.

It can be divided into forward sections.

Large sprockets are placed at the inflection point between the upwardly inclined forward section and the upwardly inclined backward section where the circulation direction of the screen belt is changed, and at the inflection point between the downwardly inclined backward section and the downwardly inclined forward section, and small sprockets are placed at the remaining inflection points, so that the screen belt The driving force for circulation is transmitted through the large sprocket, and the small sprocket can be configured to serve as a guide for the screen belt circulation trajectory.

The air intake port includes a box-shaped intake portion with a suction hole formed on the front and one side and bottom of which are open; A suction tube frame formed around the suction hole and into which the suction tube is inserted and coupled; and an inclined suction portion that is laterally coupled to communicate with an open portion on one side of the box-shaped suction portion and has an open lower portion.

In addition, the present invention may be configured to further include a housing installed to cover the circular orbit and having an open portion corresponding to the open lower portion of the air intake port and the suction pipe frame.

In addition, the present invention may be configured to further include a blowing pipe that supplies a blowing airflow generated in opposition to the suction force from the suction fan to the aggregate movement path.

It can be arranged to provide suction force toward the point identified by .

1. The rotary separator adsorption separator of the present invention is configured to provide suction power by installing a screen belt that circulates along a circular track on a conveyor belt and installing a suction port in the circular track of the screen belt. Therefore, the equipment configuration is Because it is simple, the required quantity can be easily installed at the desired location among construction waste intermediate treatment facilities without interference with other facilities.

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

As shown in [FIG. 1], the present invention includes an air intake port 110 that provides suction force generated by the operation of a suction fan (not shown) and transmitted through the suction pipe 20 through the open lower portion; a plurality of rotating shafts (120) spaced apart from each other to form a circular orbit around the air intake port (110); Bearings 130 provided on both sides of the rotating shaft 120; Sprockets (140a, 140b) installed to circumscribe the bearing (130); And a chain 152 is coupled along both side ends of the separation net 151, and in a state where the chain 152 is engaged with the sprockets 140a and 140b, it circulates on the circular orbit by rotation of the rotating shaft. A screen belt 150 installed to circulate while maintaining the trajectory; It is configured to include, and the suction force provided through the air intake port 110 is applied to the lightweight foreign matter 2 in the aggregate 1 transported to the conveyor belt 10 through the screen belt 150, thereby removing the light foreign matter. (2) is transported in a state adsorbed on the screen belt 150, and is configured to be discharged in a section where the suction force is not provided.

The air intake port 110 is open toward the conveyor belt 10 transporting the aggregate 1, and the suction force generated by driving the suction fan (not shown) and transmitted through the suction pipe 20 is transmitted to the conveyor. It is provided to the aggregate transported on the belt (10). The suction power is not sufficient to suck up the aggregate, and must be provided with sufficient force to suck up foreign substances such as paper, wood chips, Styrofoam, and vinyl. To this end, the rotational speed of the suction fan, the air intake port 110, and the conveyor are adjusted. The distance between belts 10 must be adjusted appropriately. Accordingly, foreign substances such as paper, wood chips, Styrofoam, and vinyl mixed in the aggregate 1 can be sucked toward the air intake port 110. Accordingly, it is desirable to open the entire lower surface of the air intake port 110 to widen the range where the suction force is provided to correspond to the width of the conveyor belt 10.

However, in the present invention, foreign substances are not sucked into the air intake port 110, but are adsorbed on the separation net 151 of the screen belt as shown in [FIG. 11], move for a certain period, and then the suction force is reduced. It is discharged through free fall in a section that is not provided.

A circular orbit is formed around the air intake port 110, and a plurality of rotation axes 120 are installed to set and demarcate the trajectory range of the circular orbit. That is, a plurality of rotation shafts 120 are installed spaced apart around the air intake port 110 to form a circular orbit. The placement point of the rotation axis 120 becomes each inflection point of the circular trajectory, and the screen belt 150 is installed along the circular trajectory.

The fact that the screen belt 150 is installed along the circular orbit around the air intake port 110 can be interpreted as meaning that the air intake port 110 is disposed within the circular orbit. Since the suction force must penetrate the screen belt 150 and act as a force to adsorb the foreign substances, for this purpose, the screen belt 150 is arranged to pass close to the open lower surface of the air intake port 110. It is desirable.

A base frame 30 is installed in the lower part of the circumference of the circular track, a support frame, etc. is installed on the base frame 30, and the required parts of the base frame 30 and the support frame are as shown in [Figure 1]. Likewise, the anchor 50 for installing the rotary shaft 120 can be coupled, and each end of the rotary shaft 120 can be installed inside the anchor 50 to enable shaft rotation. One of the plurality of rotation shafts 120 may receive the driving force of the electric motor 40 to rotate the shaft.

The screen belt 150 is installed to circulate in a direction perpendicular to the direction of transport of the aggregate, and further includes a foreign matter discharge path 170 provided at the lower end of the circulation track of the screen belt 150, so that the discharge Interference between the furnace 170 and the screen belt 150 can be prevented.

Bearings 130 are installed on both sides of the rotating shaft 120, and sprockets 140a and 140b are installed to circumscribe the bearings 130.

The installation interval of the bearings 130 corresponds to the width of the screen belt 150. As shown in [FIG. 2], the screen belt 150 is coupled with chains 152 along both sides of the separation net 151. The screen belt 150 can keep the spacing of the chains 152 constant by combining a plurality of connecting rods 153 at equal intervals between the chains 152 on both sides.

The separating net 151 is manufactured by weaving metal threads, and is configured to weave the connecting rod 153, so that the separating net 151 and the chain 152 are indirectly coupled through the connecting rod 153. It can be done as much as possible. The separation net 151 can be formed by weaving it in the form of a rhomboid net, a grid net, etc.

The chain 152 forms a chain-sprocket structure engaged with the sprockets 140a and 140b, and accordingly, the screen belt 150 maintains a circular trajectory on the circular trajectory by rotating the rotation shaft 120. You can circulate while doing this.

As the rotation axis 120 is disposed at each inflection point of the circular trajectory, the circular trajectory is formed along the circular direction of the screen belt 150, such as a lower forward section, an upward sloping forward section, an upward sloping backward section, an upper side backward section, and a downward sloping section. It is divided into an inclined backward section and a downward inclined forward section. A large sprocket (140a) is installed at the inflection point between the upwardly inclined forward section and the upwardly inclined backward section where the circulation direction of the screen belt 150 is changed, and at the inflection point between the downwardly inclined backward section and the downwardly inclined forward section, and small sprockets are installed at the remaining inflection points. (140b) is installed so that the driving force for circulation of the screen belt 150 is transmitted through the large sprocket 140a, and the small sprocket 140b serves as a guide for smooth circulation within the circulation track of the screen belt 150. It can be configured to do this.

That is, at least one of the two rotation shafts 120 that pass through the inflection point that is the installation point of the large sprocket 140a is the main rotation shaft that rotates by directly receiving the driving force of the electric motor 40, and the electric motor 40 ) The rotating shaft 120, which does not directly receive the driving force, becomes a driven rotating shaft that rotates dependently through the above-described chain-sprocket structure according to the shaft rotation of the main rotating shaft.

The driving force of the electric motor 40 applied to the main rotating shaft is transmitted to the large sprocket 140a through the bearing 130, and is transmitted to the driven rotating shaft through the chain-sprocket structure according to the circulation of the screen belt 150. Since the transmitted rotational force is also transmitted through the bearing 130, the screen belt 150 circulates smoothly within the circular orbit.

[Figure 3] is a photograph of the chain-sprocket structure of the present invention. A disk-shaped reinforcement (145a) was coupled to the rear of the large sprocket (140a) and a ring-shaped reinforcement (145b) was combined to the rear of the small sprocket (140b) to ensure a sufficient contact surface with the bearing 130.

The suction force provided through the air intake port 110 is applied to the foreign matter 2 in the aggregate 1 transported to the conveyor belt 10 through the screen belt 150, and the foreign matter 2 is transferred to the screen. It is transported in a state adsorbed on the separation net 151 of the belt 150 and discharged from a section where the suction force is not provided.

However, when applying a general hood-type air intake, uniform suction power is provided throughout the lower opening, so even if the uniformly provided suction power is blocked in a specific section, lightweight foreign substances (2) may not fall and be discharged immediately.

Accordingly, in the present invention, a suction hole 111 is formed on the front and a box-shaped suction part 112 with one side and bottom open; A suction tube frame 113 formed around the suction hole 111 and into which the suction tube 20 is inserted and coupled; and an inclined suction portion 114 that is laterally coupled to communicate with an open portion on one side of the box-shaped suction portion 112 and has an open lower portion; It includes a suction power control type air intake port (110) configured to gradually decrease the suction power provided from the box-shaped suction unit (112) toward the outside of the inclined suction unit (114).

[FIG. 4] is a perspective view of an embodiment of the suction power control type air intake 110 as above, and [FIG. 5] shows the plane (a), front (b), and right side (c) of the suction power control type air intake 110. will be. Hereinafter, the direction of the plane, front, left and right sides, bottom, etc. for explaining the suction power controlled air intake (hereinafter abbreviated as 'air intake') will be explained based on [Figure 5].

As shown in [FIG. 4] and [FIG. 5], the air intake port 110 is a box-shaped suction part 112 and an inclined suction part 114 combined laterally.

The box-shaped suction part 112 has a suction hole 111 formed on the front, and one side and bottom are open.

The inclined suction part 114 is laterally coupled to communicate with an open portion of one side of the box-shaped suction part 112, and has an open lower part, so that the suction force provided through the suction hole 111 is applied to the inclined suction part 112. It also reaches the suction section 114. The entire side of the inclined suction part 114 in contact with the box-shaped suction part 112 may be opened, or a lateral communication opening may be formed in some sections. The lateral communication opening can be formed of a plurality of through holes. In this case, the suction force provided to the inclined suction part 114 can be controlled for each part by adjusting the arrangement and diameter of the plurality of through holes.

The suction hole 111 is provided with a suction pipe frame 113 coupled to the suction pipe 20. The shape and size of the suction hole 111 and the suction pipe frame 113 are not specifically limited, but can provide suction power to select lightweight foreign substances 2 mixed in the aggregate transported on the conveyor belt 10. It can be appropriately designed to allow air flow, and combining the cylindrical suction tube frame 113 with the circular suction hole 111 is appropriate in terms of air flow.

The suction force provided through the suction tube frame 113 is provided to the conveyor belt 10 through the open lower part of the air intake port 110, but the box-shaped intake port 112 and the inclined intake port 114 are configured according to the structure. As the box-shaped suction part 112 moves outward from the inclined suction part 114, the suction force provided through the suction tube frame 113 gradually decreases.

On the other hand, if the suction power cannot be sufficiently reduced only by the morphological characteristics of the inclined suction part 114, a horizontal perforated plate 115 with a plurality of through holes formed in the plate surface can be installed in the middle of the inclined suction part 114. The size of the suction force passing through the inclined suction part 114 can be controlled depending on the size and number of the through holes. Specifically, the through hole disposed on the side of the box-shaped suction part 112 can be formed relatively large so that the suction force changes gently at the boundary between the box-shaped suction part 112 and the inclined suction part 114.

In order to variably control the suction force provided through the inclined suction part 114, a guide frame 116 installed in parallel along the lower front and rear lines of the inclined suction part 114 and a plurality of holes (h) on the plate surface are installed. It may be configured to further include a suction power control plate 117 that is formed and slides along the guide frame 116 to adjust the indentation distance.

The suction power control plate 117 is pushed to the maximum inside of the guide frame 116, so that the suction power control plate 117 becomes the bottom surface of the inclined suction part 114, and suction power is provided only through the hole (h). Alternatively, the lower part of the inclined suction unit 114 may be left completely open by pulling the suction power control plate 117 out of the guide frame 116. Of course, by pushing only a part of the suction power control plate 117 toward the inclined suction part 114, the lower part of the inclined suction part 114 is opened on the inside to provide a relatively large amount of suction power, and the outside is exposed to the suction power control plate. It is blocked by (117) and can be controlled to provide a small amount of suction force only through the through hole (h).

In addition, the suction power control panel 117 can control the size of the suction power passing through depending on the size and number of holes (h), so the positions of the large diameter and small diameter holes on the plate surface of the suction power control panel 117. By arranging the and quantity, the suction power transmitted can be controlled more precisely.

[Figure 6] shows an embodiment of the suction power control plate 117 in which the diameter of the through hole varies for each section, and the suction power control plate 117 is conceptually divided according to the size of the through hole (h). In order to smoothly discharge foreign substances, the suction force must decrease as it moves toward the outside of the inclined suction part 114. Therefore, a relatively large diameter hole h1 is located inside the inclined suction part 114, and a relatively small hole is located outside the inclined suction part 114. The suction power control plate 117 can be inserted and installed along the guide frame 116 with (h4) positioned.

The horizontal perforated plate 115 and the suction power control plate 117 can be selectively applied or applied together in the air intake port 110 of the present invention.

As described above, by applying the air inlet 110 in which the box-shaped suction part 112 and the inclined suction part 114 are laterally combined, the air inlet 110 is applied to the outside of the inclined suction part 114 as shown in [FIG. 9]. As the suction force gradually decreases and the suction force is completely blocked at an appropriate position, the foreign matter 2 can be configured to be smoothly discharged through the discharge passage 170.

Meanwhile, as suction force is provided through the suction hole 111 on the front of the box-shaped suction part 112, the air sucked through the open lower part is the main airflow that is sucked into the suction pipe 40 through the suction hole 111. A vortex is formed in the space outside the main airflow path within the box-shaped suction part 112, as shown in [FIG. 9], and the vortex becomes an element that interferes with the smooth flow of the main airflow.

Accordingly, a curved plate 118 is installed inside the box-shaped suction part 112 downward from the top of the front side to the rear side, so that the inner space of the box-shaped suction part 112 is segmented by the curved plate 118, thereby forming a vortex. can be prevented.

Meanwhile, foreign substances such as vinyl pieces may be attached to the separation net 151 of the screen belt 150 due to static electricity.

Accordingly, a curtain net 154 as shown in [FIG. 8] below can be installed on the outer surface of the separation net 151. The curtain net 154 is configured so that the upper end is installed in the width direction of the separation net 151 and the lower end does not contact the conveyor belt 10. A plurality of curtain nets 154 are connected to the separation net 151. They can be combined at equal intervals. The curtain net 154 may be made of a net of the same material and structure as the separation net 151.

By adding the curtain net 154 to the separation net 151 as described above, the foreign matter 2 is prevented from flying out of the circular orbit of the screen belt 150 due to suction force, and the centrifugal force and The shaking of the curtain net due to inertia and gravity can contribute to the foreign matter 2 falling to an appropriate location and being discharged (see [FIG. 9]).

In addition, the rotary separator adsorption sorter 100 of the present invention is installed to cover the circulation track, and further includes a housing 160 with an open lower part of the air intake port 110 and an opening corresponding to the suction tube frame. It can be configured (see Figure 11).

The housing 160 can protect the screen belt 150 from the external environment and cover dust scattered during the foreign matter adsorption process.

In addition, the present invention further includes a blowing pipe (not shown) that supplies a blowing airflow generated in opposition to the suction force from the suction fan (not shown) to the aggregate movement path, thereby levitating foreign substances pressed under the aggregate. It can be easily adsorbed to the screen belt 150.

Additionally, by arranging the air intake port 110 to be open toward the point where the aggregate falls from the conveyor belt 10, foreign substances scattered during the fall of the aggregate can be selected.

In addition, when the conveyor belt 10 is installed by dividing it into an upper part and a lower part that intermittently provides an aggregate transport path, the air intake port 110 is directed toward the point where the aggregate falls from the upper part to the lower part. It can be installed at an angle so that it is open. According to the arrangement of the air intake port 110, foreign substances break away from the conveyor belt 10 and are easily adsorbed to the separation net 151 of the screen belt 150 by the suction force provided by the air intake port 110. It can be done as much as possible.

In addition, a bumper (not shown) is installed at the bottom of the section immediately before the air intake port 110 during the conveyor belt 10's travel path, and aggregates and foreign matter are removed during the process of the conveyor belt 10 passing over the bumper. In this lightly bounced state, only light foreign substances can be adsorbed to the separation net 151 of the screen belt 150.

In addition, a rake (not shown) is installed at the upper part of the section immediately before the air intake port 110 during the conveyor belt 10's travel path, and the rake scatters the aggregate on the conveyor belt 10 so that foreign substances are removed from the conveyor belt 10. The screen belt 150 can be adsorbed more efficiently.

The present invention can be configured by applying two or more of the above-described means to improve foreign matter adsorption efficiency.

In the above, the present invention was examined in detail along with specific examples. However, the present invention is not limited to the above examples and may be modified and modified without departing from the gist of the present invention. Accordingly, the scope of the claims of the present invention includes such modifications and variations.
