BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crushing and separating-

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recycling aggregate material crushing and separation and sorting apparatus for concrete, and more particularly, to a crushing and separating and sorting apparatus for recycling aggregate material for concrete that can separate cement residue or sand from recycled aggregate more cleanly will be.

Furthermore, it is possible to apply a strong impact to the recycled aggregate, thereby crushing the recycled aggregate as well as crushing it, and removing the foreign matter and the concrete paste attached to the aggregate surface to produce a clean recycled aggregate. .

In particular, a plurality of guide rollers are installed vertically and horizontally to firmly support the rotary drum. In addition, a rotary roller having a sprocket and a rotary roller as a means for rotating the rotary drum and pushed by the sprocket, The rotating drum rotated by the sprocket rotates to reduce the friction between the sprocket and the rotating roller so that the rotating drum can be easily rotated and the strength of the crushing blade installed inside the drum is reinforced, And more particularly, to a recycling aggregate material crushing and separation and sorting apparatus for concrete which improves the separation effect of foreign matter by applying a strong impact.

Buildings and civil engineering structures (hereinafter referred to as "buildings") are mainly made of reinforced concrete and concrete, and their service life is limited. In the process of dismantling buildings that have reached the end of their life, a large amount of waste is discharged, and these construction wastes are mainly disposed of by reclamation on reclaimed land and landfills.

However, since the amount of construction waste is large, the landfill is not enough to be landfilled, and it is costly, so that it is frequent to dump on the road side, and the dumped construction waste causes not only aesthetics but also environmental pollution.

On the other hand, the amount of aggregate required is increasing due to the increase of new construction and reconstruction, but the amount of natural aggregate is limited, and the collection of aggressive aggregate from river and mountain is prevalent. In addition, although aggregate collected from the sea is supplied to supply scarce aggregate, since aggregate collected from the sea contains salt, many processes must be performed in order to remove salinity, so that the productivity is lowered. And there is a concern that the construction will be carried out because it is not discharged.

In order to solve the above-mentioned problems, a method of selecting aggregates from construction waste and reusing them has been used.

A device for regenerating construction waste is a construction waste regeneration or treatment device (hereinafter referred to as "construction waste treatment device"). The construction waste disposal apparatus is a device for producing gravel or sand (hereinafter referred to as "recycled aggregate ") by crushing waste concrete contained in construction waste. The apparatus includes a crusher for crushing waste concrete to an appropriate size, And a foreign matter separating device for separating foreign materials such as wood, vinyl, rubber, paper and plastic mixed in the crushed architectural waste.

The regenerated aggregate regenerated by such a conventional construction waste disposal apparatus is adhered with foreign matter (hereinafter referred to as "foreign matter") such as cement, soil, and wood chips. When recycled aggregate mixed or adhered with foreign matter is used, there is a problem that the strength of the building becomes weak because the adhesion between the recycled aggregate and the cement is weakened. Accordingly, various methods have been used to remove foreign matter from recycled aggregate, and one of them is a method of washing recycled aggregate with water. However, in order to wash recycled aggregate with water, not only a large amount of water is required, but also it is costly, and there is a problem that the washed water of the recycled aggregate contaminates the soil or the water quality.

Among recycled recycled aggregates, cement and sand are attached to large aggregates such as gravel (collectively referred to as "coarse aggregate " hereinafter), and such foreign matter is left unremoved from aggregates even when washed with water .

In order to overcome such disadvantages, Patent Document 1 has been developed by the present applicant.

A tubular housing having an inlet and an outlet through which recycled aggregate is injected and discharged; A plate-shaped brush installed under the inlet and reciprocating horizontally to scrape off foreign matter on the surface of the charged recycled aggregate; And driving means for reciprocating the plate brush horizontally.

It is possible to cleanly separate and remove the foreign matter attached to the recycled aggregate without using water, but there is a problem that the sand or cement residue adhered to the aggregate by the cement remains in the aggregate.

Another prior art is Patent Document 2. As shown in FIG. 6, the apparatus for separating foreign materials of recycled aggregate has an inlet formed at the upper part thereof for separating foreign materials such as soil, dust, and calcarea attached to recycled aggregate such as sand and gravel recovered from construction waste, A rotating drum (300) mounted on the inside of the drum and hitting the recycled aggregate by installing a plurality of striking blades on a rotating shaft rotated by the motor, and a drum (300) And a bending layer (200) having a conical conical curved surface is provided. By separating the foreign materials adhering to the aggregate by blowing the recycled aggregate charged into the inlet through the inner wall of the drum, It is possible to obtain a clean recycled aggregate by separating the foreign matter from the recycled aggregate, but the impact applied to the recycled aggregate discharged by the rotating car is weak There is a disadvantage in that the foreign matter attached to the recycled aggregate can not be sufficiently separated.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

Like reference numerals are used for like elements in describing each drawing. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention makes it possible to apply a strong impact to the recycled aggregate, so that the recycled aggregate is crushed as well as crushed, so that clean recycled aggregate can be produced.

Furthermore, it is possible not only to stably support the rotary drum, but also to be rotatable.

The apparatus for crushing and separating recycled aggregate materials for concrete according to the present invention is supported by two vertical and horizontal guide rollers 10v and 10h installed on the upper and lower ends of the outer circumferential surface of the rotary drum 10 and installed on the support frame 100 A guide blade (12) capable of preventing shaking when the rotary drum rotates; And a plurality of rotating rollers 13 that are rotated by the rotation of the rotating sprocket 21 by receiving the power of the drum driving motor 20 to rotate the rotating drum and minimize friction with the sprocket by rotating the rotating drum have.

3, the guide vanes 12 are respectively provided at the upper and lower ends of the rotary drum 10 and are supported by vertical guide rollers 10h for supporting the side surfaces, And the bottom surface is supported by the horizontal guide roller 10v so that the rotary drum 10 can be stably rotated without being moved in the vertical direction.

1, the rotating roller 13 and the sprocket 21 substantially receive the rotational force of the drum grazing motor 20 from the sprocket 21 as means for rotating the rotating drum 10, The sprockets formed on the sprocket push the rotating roller 13 in the direction in which the rotating drum rotates so that the rotating drum rotates.

At this time, as the rotary roller 13 rotates when it is pushed against the projection of the sprocket, friction between the sprocket and the rotary rollers 13 is small, so that the rotary drum can be rotated more effectively.

The apparatus for crushing and separating recycled aggregate materials for concrete according to the present invention has a similar structure to that of Patent Document 2 filed and registered by the applicant of the present invention.

That is, the apparatus for crushing and separating recycled aggregate materials for concrete according to the present invention comprises a cylindrical rotating drum 10 having a cylindrical cylindrical shape and having a plurality of crushing blades 11 formed on the inner wall thereof; A drum driving motor 20 installed at one side of the rotary drum and rotating the rotary drum 10; The lower end of the rotary drum 10 is rotatably installed by a thrust bearing 31b and the upper end of the rotary shaft 31 is provided with a pulley 31p. A damper 30 for blowing the foreign matter adhering to the crushing blade 11 installed on the inner wall of the rotary drum 10 by the impact of the aggregate introduced into the drum 10 and separating the foreign matter attached to the aggregate and crushing and crushing the aggregate; And a filtration device 40 installed at the lower portion of the rotary drum 10 to separate and discharge waste matter mixed with the crushed and crushed aggregate discharged from the rotary drum and the foreign material and discharge the discharged material according to the size of the particles.

As shown in FIGS. 1 to 3, the rotary drum 10 has a cylindrical tubular shape. Upper and lower ends thereof are opened, recycled aggregate is fed to the upper end, and crushed and foreign materials The aggregate is discharged.

As shown in FIG. 2, the filtration apparatus 40 is constituted by providing filtration nets 41, 42, 43 in multiple stages.

An upper end of the intermediate filtering net 42 which is inclined to the lower end of the inclined upper filtering net 41 is opposed to a lower end of the lower filtering net 41, And the lower end of each filter net is provided with discharge ports 41o, 42o and 43o.

Such a filtration apparatus 40 gradually separates small particles from the upper filtration net 41 toward the lower filtration net 43.

Each of the filtering nets 41, 42 and 43 of the filtering device 40 is resiliently supported by the spring 40s so that the foreign matter can be easily passed through the filter net by the impact when the aggregate is dropped on the upper surface thereof.

That is, the aggregate can be selected without clogging the mesh of the filter net by the impact of falling aggregates falling from the upper part. However, since the aggregate can not be sufficiently sorted by the impact caused by the falling of the aggregate, a vibration network supporting frame 40p for supporting the filtering nets 41, 42 and 43 vibrates the filtering net to accelerate the discharge of foreign matter. It is preferable to further provide the second electrode 40v.

The vibrating device 40v can be variously modified. For example, the driving cam can be rotated by a motor to vibrate the support frame 40p.

In addition, the apparatus for crushing and separating recycled aggregate materials for concrete according to the present invention is capable of crushing and sorting recycled aggregate, For this purpose, the crush blades 11 include a swash plate 11s which forms a trumpet-shaped lowered light beam; And a horizontal plate 11h horizontally installed between the inner end of the swash plate 11s and the inner wall of the rotary drum.

The angle of the swash plate 11s preferably has a horizontal plane perpendicular to the rotation axis and an angle of 30 to 60 degrees.

When the angle of the swash plate is less than 30 °, the angle of impact of the agitated material impacted by the impact blades (30) collides with the crushing wing, and then the angle of reflection is broadened to hit the inner wall of the rotary drum. The aggregate can be excessively crushed by repeating the process in which the aggregated material blown toward the impact wing is again blown by the impact wing, and when the angle of the swash plate is 60 ° or more, it is hit by the impact wing, It is preferable to control the angle of the swash plate in the above range and the optimum slope is 45 deg. Since the fractured effect toward the aggregate fed with the aggregate may be lowered by the direction of the reflected aggregate being directed upward.

Also, the upper and lower intervals between the crush blades 11 provided in multiple stages are preferably such that the aggregate reflected by the swash plate 11s can hit the bottom surface of the horizontal plate 11h.

Further, a repair hole 10h is formed in a side wall of the rotary drum 10, and a door can be opened and closed to facilitate maintenance when an error occurs inside the rotary drum.

The feeder 50 pushes the recycled aggregate fed into the hopper 50h to the lower outlet by rotating the feed vane 50w to feed the recycled aggregate into the rotary drum 10, In order to adjust the amount of aggregate, it may be accomplished by adjusting the rotational transmission of the feed motor 50m.

That is, since the regenerated aggregate piled on the feed vane 50w can not move downward unless the feed vane rotates, the feed rate of the regenerated aggregate can be controlled by adjusting the rotation speed of the feed vane, To adjust the rotation speed of the supply motor 50m.

In addition, the apparatus for separating and separating recycled aggregate materials for concrete according to the present invention includes a repair stand (60) for enclosing the lower end of the rotary drum (10), so that the operator can climb up to facilitate maintenance.

4, a reinforcing piece 30r is additionally provided in the middle of the impact blades 30 to reinforce the strength of the impact blades 30 and, in addition, So that the direction in which the aggregate is repelled is varied.

In the apparatus for crushing and separating recycled aggregate materials for concrete according to the present invention, the rotary drum and the impact blades are rotated in opposite directions, so that the aggregate material blown by the impact blades rotates in opposite directions, I was hit harder by a stronger impact.

Further, a transmission gear assembly 20t is further provided between the drum driving motor 20 and the sprocket 21 so as to more easily adjust the rotating speed of the rotating drum, and the rotation speed of the rotating drum is accelerated or decelerated I can do it.
