The present invention relates to an apparatus for producing circulating aggregate of construction waste having vortex removal blowing means, and more particularly, which is generated during operation of a blower for removing foreign matter contained in the final recycled aggregate falling from the end of the conveyor to the reservoir during the production of circulating aggregate. The present invention relates to a method for removing vortices by removing vortices to produce recycled aggregates having improved foreign matter classification efficiency by blowing.

Many construction wastes come out during the demolition of buildings and civil structures, and the landfill of such construction wastes is limited and causes many environmental pollution problems.

Due to the above problems, illegal landfill of construction wastes is prohibited, and a method of classifying, processing, and recycling necessary aggregates is highly recommended.

Looking at the contents of the construction waste, it contains large amounts of sand and gravel mixed concrete, reinforcing bars, electrical wiring, paper, vinyl, plastics, etc., because it has moved the broken building.

Therefore, in order to recycle the construction waste, large concrete blocks should be shredded finely and sorted by size, and rebar, electrical wiring, paper, vinyl, plastics, etc. will be separately sorted.

When describing the circulating aggregate production device to be supplied to the construction waste as described above to produce the final recycled aggregate through the various stages of the selection process has the following device configuration.

That is, a hopper to which construction waste is supplied: a circular sorter which rotates the construction waste supplied from the hopper to classify soil and aggregates having a predetermined size or less; A crusher such as a jaw crusher or a cone crusher for crushing the construction waste aggregate of a predetermined size or more through a circular separator into a recycled aggregate of a predetermined size or less; A magnetic separator for classifying metals from recycled aggregates having a predetermined size or less through a crusher; And a blower for blowing and classifying light foreign matters such as paper or vinyl contained in the recycled aggregate after the magnetic separator.

In particular, the blower is to blow the falling aggregate in the same direction as the conveyor by installing a blower at the lower end of the end of the final conveyor device for transporting the aggregate classified in the crushing and sorting step, the feeder sandwiched between the aggregate and aggregate It is a device to classify wood, vinyl, etc. to produce only good aggregate.

However, the above-mentioned blower is well classified in the early stages of the recycled aggregates, such as vinyl or tributary fly to the foreign matter collection area, but after a certain distance scattered vortex occurs, and some of the vortex is not flying toward the intended collection There was a problem that the quality of the recycled aggregates was degraded while revolving in the space where the recycled aggregates were dropped.

This configuration using the conventional blower is illustrated in Figure 6 the embodiment of the prior art, the transfer of the recycled aggregate sorted by the blower according to the conventional blower is illustrated in Figure 7 well, and the conventional blower Vortex phenomena occurring during classification of foreign matters are well illustrated in FIG. 8.

In spite of the above problems, there is still no device for eliminating the vortex, and thus there is a limit to increasing the quality of the final recycled aggregate.

An object of the present invention for solving the problems described above is a vortex generated in a certain space according to the operation of the blower when classifying foreign matters such as vinyl, paper, etc. mixed between the recycled aggregate crushed to a certain size in the construction waste production apparatus It is to provide a vortex removal method that removes the phenomenon to increase the blowing classification efficiency to produce a high quality recycled aggregate.

The present invention to achieve the object as described above and to perform the problem for eliminating the conventional defects and a hopper to which construction waste is supplied; A circular sorter for rotating the construction waste supplied from the hopper to classify soil and aggregates of a predetermined size or less; A crusher such as a jaw crusher or a cone crusher for crushing the construction waste aggregate of a predetermined size or more through a circular separator into a recycled aggregate of a predetermined size or less; A magnetic separator for classifying metals from recycled aggregates having a predetermined size or less through a crusher; A blower installed at the lower end of the conveying conveyor to blow-out classification of light foreign substances such as paper or vinyl contained in the recycled aggregate being conveyed to the conveyor through the magnetic separator; In the recycling aggregate production method using a construction waste recycling aggregate production device comprising a conveyor installed horizontally or inclined to connect the respective devices,

The blower installed at the lower end of the conveying conveyor is installed at a predetermined distance apart from the blower so as to face the blowing flow with a constant upward angle, and provided with a vortex removal slope film having at least one perforation formed on the surface in the blower After letting the blown wind flow in,

It is provided with a blowing bypass pipe installed in the perforated portion formed in the vortex removal inclined film for the vortex removal flow to change the direction of the blown wind in any direction,

At the same time, the upper air flow path blocking membrane is extended to the conveyor belt in contact with the upper surface of the vortex removal inclined film in the wind flowing from the blower installed at the lower end of the conveying conveyor, and then the upper blower is installed at the upper end of the conveying conveyor. It is characterized by a method of removing the vortex by increasing the inflow to the perforated portion formed in the vortex removal inclined film by supplying the air in the horizontal direction blowing additional wind of a constant air flow.

In order to prevent the foreign matter discharged downward by changing the flow path by the blowing bypass, the recycled aggregate dropped from the end of the conveying conveyor is mixed with the foreign matter blocking slope film so that the flow path is changed upward. It is characterized in that the air flow including a configuration to be introduced into the air stream injected from the blower.

Hereinafter, the configuration and the operation of the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is an exemplary view showing an embodiment configuration of the present invention, Figure 2 is an exemplary view showing an embodiment configuration of the state equipped with a foreign matter scattering prevention network of the present invention, Figure 3 is a blow-classified regeneration according to the present invention Figure shows an example showing the transfer of aggregate, as shown in the configuration, the vortex removal inclined film (1) for continuously absorbing the blown wind from the blower installed at the lower end of the conveying conveyor to remove the vortex generation It is provided by supporting members, such as a frame.

The vortex removal inclined film 1 of the present invention is installed spaced apart from the blower 2 by a predetermined distance, and at least one perforated part 11 is formed on the surface, and the air blower is randomly formed along the perforated part 11. By flowing along the flow path to the position of the eddy currents such as vortex flow is eliminated.

The perforated portion 11 is configured to be installed so that the blow-by-pipe connection portion 12 protrudes to the opposite side of the vortex removal inclined film 1 surface which is in contact with the blowing flow. Accordingly, the flow of the air flows at a fixed angle of the blower tube connecting portion 12 installed at the rear end of the vortex removing slope 1, and the flow path is adjusted according to the design of the installer. Is changed.

The predetermined distance spaced apart from the blower 2 refers to the distance to the vortex generating position generated by the blowing force of the blower 2, and the vortex removing slope film 1 is installed at this position. This position is variable depending on the pen blade size, rotational speed and blower motor capacity of the installed blower 2, not a fixed distance or position.

Therefore, according to the characteristics of the blower (2) installed at the time of installation may be installed after checking the vortex generation position. At this time, the number of revolutions of the motor, etc. may vary, but it is sufficient if the amount of recycled aggregates falling from the recycled aggregates is maximum based on the blowing force such that foreign matters are scattered.

The reason for checking and installing the vortex generation position is that the vortex removal slope film 1 is installed too far behind the vortex generation position so that the airflow at the vortex generation point does not flow toward the vortex removal slope film 1 even by the air volume of the upper blower. If the vortices are not removed in the end, there is no reason for the installation of the present invention, and if it is installed too far ahead of the vortex generating position, the wind generated from the blower 2 is too strong so that the recycled aggregates and the light recycled aggregates are separated before the foreign matters are classified. This is because foreign matter is sucked together into the perforations 11 of the vortex removal inclination film 1.

At least one blower tube 3 for changing the blower airflow in an arbitrary direction is installed at the blower tube connecting portion 12 protruding at the rear end of the perforated part 11 formed on the vortex removing slant film 1. By using the ventilation duct 3, the installer can freely adjust the flow of air near the vortex generating point according to the situation of the production site of recycled aggregate.

It is usually designed in a downward direction and directed towards the collection bin where foreign objects are collected. In the past, when there were no such ventilation houses (3), the process of collecting the foreign matters again after the classification of the foreign matters was necessary by scattering the foreign matters freely in a large area instead of a specific space. However, when using the blow bypass tube (3) of the present invention, it is possible to collect even when using a small collection box by discharging within the diameter of the blow bypass tube (3) having a certain size, the collection installation area is significantly reduced when designing the foreign matter sorting device The collection device can be miniaturized.

Such a blow bypass tube 3 may be installed to have a fixed flow path using a hard material, but if the bellows pipe is made of a flexible material to change the flow path freely, it may be configured to have more and more various flow paths.

The upper surface of the vortex removing membrane 1 for vortex removal is provided with an upper air flow path blocking membrane 4 connected to the upper air blower installed in contact with the upper side of the conveyor belt, and the purpose of installation is different from the wind blown by the lower air blower 2. The airflow blown from the lower part flows toward the vortex removal inclination film 1 to flow to the perforation part 11, and at the same time, the blower air flow generated from the upper blower is uniformly vortex removal inclination film along the flow path. 1) to provide an additional blower air flow to the blower air flow supplied from the lower side to be more smoothly supplied to the vortex removal slope film (1).

At one end of the upper air flow path blocking membrane 4, an upper blower 6 for providing an additional blowing force toward the vortex removal inclined film 1 is installed at an upper end of the conveying conveyor, and the blower generated by the upper blower 6 is The vortex breaks off the eddy of the foreign matter caused by the vortex phenomena and is substantially transferred to the vortex removal inclined film 1. That is, the balance of the vortex phenomena generated by the updraft of the blower 2 supplied from one side downward direction and the airflow acting as a kind of load in the opposite direction of the raised airflow is added to the additional airflow supplied by the upper blower 6. As a result, the balance is broken so that the airflow supplied from the blower 2 flows into the constant airflow toward the vortex removal gradient film 1 without vortexing.

The foreign matter blocking slope film 5 is installed to prevent the foreign matter discharged by changing the flow path by the blowing bypass pipe 3 and the recycled aggregate dropped from the end of the conveying conveyor. This foreign matter blocking inclined film 5 is configured to have an upward angle so that the wind direction supplied from the blower bypass 3 proceeds upward.

On both sides of the upper air flow path blocking membrane 4, a blocking network 7 is installed to prevent diffusion of scattered foreign matter. The material of the screening net 7 may be made of steel or synthetic wire rope.

In addition, the rear end of the vortex removal inclined film (1) and the outer portion of both sides of the blocking network (7) further comprises a foreign matter scattering prevention net (8) is configured to prevent the scattering of foreign matters that are not collected or scattered too far by collecting. . The material of the anti-fog shatterproof film may be made of iron or synthetic wire rope.

The blower (2) is sufficient to use the blower (2) capable of generating a rotational force by connecting the power generated from the motor to the chain or belt, and change the shape or position of the discharge port,

The upper blower 6 is sufficient to use a rotational force is generated by directly connecting the motor and the pen like a general ventilation device or a fan. Therefore, you may use the thing which does not have a separate discharge port structure.

Although not shown in the drawings, the recycled aggregate mixed with the foreign matter supplied through the conveyor of the present invention may increase the blowing efficiency of the blower 2 to the foreign matter when dropped in a wide spread state.

The means for spreading the foreign matter on the conveyor belt in this way may be used as any means, and it is sufficient to simply supply it as such.

For example, when the recycled aggregate spreading means or method such as 'free up and down buffer and left and right rotation means' disclosed in the applicant's prior registration No. 10-2005-0112073 is used for shearing, the sorting efficiency due to blowing is increased. .

Figure 4 shows an exemplary view showing the front of the vortex removal inclined film constituting the present invention, as shown in the perforated part 11 formed in the vortex removal inclined film (1), the blowing air hall (3) formed in the middle It can be seen that the two perforations (11) and the blowing air bypass (3) and the auxiliary perforations (11) and the auxiliary blowing bypass (3) installed on the left and right. However, the size and number of such a perforation 11 does not limit the shape or number of the perforations 11 of the present invention. Only one perforation part 11 may be sufficient, and it can also be comprised by the vortex removal film 1 for vortex removal which was perforated innumerably. Only the reason illustrated in FIG. 2 is to show a preferred embodiment in which the most preferable blowing flow when measuring the size and shape is shown.

FIG. 5 is an exemplary view showing a blowing path flowing through the vortex removal inclined film constituting the present invention, wherein the blower air supplied from the lower blower 2 and the horizontal blower 6 are supplied from the upper blower 6. It can be seen that the air streams are combined to flow through the perforation portion 11 of the vortex removal inclined film (1), and then the air flows up toward the foreign matter collection unit at the lower part through the air blower (3).

In addition, it can be seen that the airflow is increased by the foreign matter blocking inclined film (5) and sucked toward the airflow generated in the lower blower (2), because the flow of airflow rising from the blower (2) is faster. This is because the surrounding air is sucked into it. In addition, the reason why the airflow is continuously increased in this way is that no vortex occurs and flows into the perforation part 11, there is no accumulation of airflow, and the additional air blower of the upper upper blower 6 is added, thereby increasing the flow of airflow. .

Referring to the effects of the present invention configured as described above are as follows.

Recycled aggregate When the recycled aggregate shredded below a certain size supplied through the conveying conveyor is supplied with vinyl or feeder and falls freely at the end of the conveying conveyor, the recycled aggregate falls freely to the lower part and falls to the temporary aggregate collecting stand. After the ascending conveyor is dropped to the loading place to load a certain amount of recycled aggregate.

On the other hand, the light feeder or vinyl is scattered again without falling by the blowing force of the blower 2 installed in the lower part of the conveyor when it falls, and merges with the airflow supplied from the upper blower 6, and the vortex removing slope film ( After the flow of a certain air flow toward 1) through the perforated portion 11 formed on the surface of the vortex removal inclined film is moved along the air blow bypass (3) and collected in the collection box.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

As described above, the present invention has no vortex phenomenon when classifying foreign matters by blown using a blower to the construction waste mixed with recycled aggregates and foreign substances shredded below a certain size, so that the efficiency of blowing classification efficiency is high. It is a useful invention having the advantage of being possible is an invention that is expected to be greatly used in the industry.
