In general, river gravel and sand produced from natural sources are limited, and the natural environment is destroyed by collecting them. Therefore, it is necessary to meet the demand of coarse aggregate or sand used in the concrete industry However, due to problems such as environmental destruction, it is difficult to collect aggregates.

On the other hand, the construction waste generated by the construction work is suitable for use as recycled aggregate in terms of environmental friendliness and recycling of resources. That is, when the construction waste is used as recycled aggregate without being buried, it is desirable from the viewpoint of recycling of resources. Recently, the construction waste is recycled as recycled aggregate through a recycling process such as crushing the construction waste to a certain size and removing foreign matter .

However, the recycled aggregate produced through such a process has a higher water absorption rate than natural aggregates due to the cement mortar attached to the aggregate surface, and when used as concrete aggregate, there is a problem such as workability, strength and durability of recycled aggregate concrete It is not actively utilized in the industrial field.

Thus, many mortar peelers and rotor units (Korean Patent No. 10-0994728) have been developed to peel off the concrete attached to the surface of recycled aggregate.

1 to 5, a mortar peeler 1 (hereinafter, a mortar peeler 1) for producing a concrete aggregate for concrete according to an embodiment of the present invention includes a vibrating body 20, a rotating part 40 ), A second liner (R2) and a first liner (R1).

In the vibrating main body 20, a cylinder 10 is laid horizontally, an inlet 10 for injecting waste aggregate is located at one end of the upper part, and an outlet 10 'for discharging recycled aggregate from which mortar is peeled off is located at the lower end, The third liner R3 is attached and connected to the vibration motor M1 and the crank device 30 to vibrate (①).

The rotary part 40 has a center axis P passing through the center of the oscillating body 20 and connected to an external drive motor M2 to rotate (②).

A plurality of second liner (R2) are attached to the outer circumferential surface of the rotary part (40) at a predetermined interval. The second liner R2 determines the separation distance between the first liner R1 and the third liner R3 and is rotated about the center axis P. [

The first liner R1 is attached to the other end of the second liner R2 and rotated with the second liner R2. The waste aggregate located between the first liner R1 and the third liner R3 is crushed by the first liner R1 and the third liner R3 or the mortar on the outer circumferential surface is peeled off to become a recycled aggregate.

Specifically, the center axis P rotates (②) and the mortar of the outer peripheral surface of the waste aggregate is peeled off between the first liner R1 and the third liner R3.

The vibrating main body 20 is disposed so as to be inclined downwardly from the charging port 10 toward the discharging port 10 'so that the waste agglomerate charged from the charging port 10 is discharged to the discharging port 10 ') 10'.

Specifically, the vibration (1) of the vibration main body 20 is vibration repeated left and right along the outer peripheral surface of the vibration main body 20, so that the waste aggregate or the recycled aggregate inside the vibration main body 20, The movement path is determined according to the shape of the movement path. Since the vibrating main body 20 is arranged to be inclined downwardly from the charging port 10 toward the discharge port 10 ', the waste aggregate or recycled aggregate inside the vibrating main body 20 is discharged from the discharge port 10' ).

The waste aggregate charged into the inlet 10 is crushed or peeled off between the first liner R1 and the third liner R3 while being moved in the oscillating body 20 and the contact with the second liner R2 It is crushed or peeled off due to impact.

The second liner R2 slides radially outward from the central axis P in the radial direction of the vibrating main body 20 by the centrifugal force resulting from the rotation of the center axis P, 3 Allow the separation distance of the liner (R3) to decrease. The positional shift of the second liner R2 will be described in detail below with reference to Figs. 6 to 9. Fig.

The second liner R2 is composed of a second liner R2-1, a second liner R2-2, a second liner R2-3, and a second liner R2-3, (R2-4).

The first liner R1 is attached to the other end of the first liner R1-1 and the second liner R2-2 attached to the other end of the second liner R2-1 The first to third liner (R1-3) and the second to fourth liner (R2-4) attached to the other ends of the first to second liner (R1-2), the second to third liner (R2-3) And a first to fourth liner (R1-4) to be attached.

Since the lengths of the 2-1 liner (R1-1) to the 2-4 liner (R2-4) are different from each other, the 1-1 liner (R1-1), the 1-2 liner (R1-2) The distance between the third liner (R1-3) and the fourth liner (R1-4) from the third liner (R3) is different.

This is to efficiently pulverize or cause surface friction of waste aggregates of various sizes and shapes. The space between the first liner R1-1 and the third liner R3, the first liner R1 2 and the third liner R3, the space between the first to third liner R1-3 and the third liner R3, the space between the first to fourth liner R1-4 and the third liner R3 R3, the pulverized or surface friction is generated while the waste aggregate corresponding to the space size is inserted.

If the space between each of the first liner R1 and the third liner R3 is the same, only the waste aggregate having a size corresponding to the space between the first liner R1 and the third liner R3 is crushed or The first liner R1 of the present invention can be prevented from being damaged by the third liner R3 depending on the length of the second liner R2, The separation distance is formed differently.

The shapes of the 1-1 liner (R1-1), the 1-2 liner (R1-2), the 1-3 liner (R1-3) and the 1-4 liner (R1-4) So that the irregularly shaped waste aggregate can be processed more efficiently.

The mortar peeler 1 according to one embodiment further includes a gravimetric measuring unit for measuring the weight of the waste aggregate or recycled aggregate that the vibrating main body 20 is accommodating in order to acquire the timing of charging the waste aggregate into the inlet 10 .

The weighing part is a kind of balance capable of measuring the weight of the oscillating body 20 or the weight of the object accommodated in the oscillating body 20. [ The weighing part allows the pulverized aggregate in the vibrating main body 20 to be put in an appropriate amount so that the mortar peeling of the outer surface of the pulverized aggregate proceeds efficiently.

Specifically, when the amount of waste aggregate contained in the vibration main body 20 is too large, the mortar peeling efficiency may be lowered by the first liner R1, the second liner R2, and the third liner R3, It may be a cause of failure of the mortar peeler 1 due to breakage or damage of the liner R1, the second liner R2 and the third liner R3. In order to prevent this, So that the waste aggregate is accommodated in the vibrating main body 20.

The mortar peeler 1 according to one embodiment may be provided with a dust-proof spring 60 for vibration reduction at a lower portion of the main body 20.

The vibration-proof spring 60 serves to keep the above-described vibration at an appropriate rhythm.

6 is a schematic view for explaining a second liner of a mortar peeler for producing recycled aggregate for concrete according to an embodiment of the present invention.

7 and 8 are schematic views for explaining a rotating part and a second liner of a mortar peeler for producing recycled aggregate for concrete according to an embodiment of the present invention.

6 to 8, the rotation part 40 of the mortar peeler 1 according to an embodiment of the present invention includes a receiving part 42 for receiving one end of the second liner R2.

The second liner R2 has an insertion portion 50 inserted into the receiving portion 42. The insertion portion 50 is in contact with the receiving portion 42 and has a centrifugal force And is slid along the outer surface of the accommodating portion 42. [

Specifically, the accommodating portion 42 has a first slanting surface portion 421 and a second slanting surface portion 422 that gradually increase in distance from the outer surface toward the center axis P.

The insertion portion 50 is formed so as to have a shape corresponding to the first slanting face portion 421 and is in contact with the first slanting face portion 421 while the other side face is formed in a shape corresponding to the second slanting face portion 422, And is in contact with the second inclined surface portion 422.

Here, the inserting portion 50 is slid along the first slope portion 421 and the second slope portion 422 by a centrifugal force acting in accordance with the rotation (2) of the central axis P.

The first inclined plane portion 421 and the second inclined plane portion 422 increase the separation distance by the insertion portion 50 when the second liner R2 is slid radially outward.

When the distance between the first slanting surface portion 421 and the second slanting surface portion 422 increases, the receiving portion 42 is elastically deformed while being in contact with the first slanting surface portion 421, When the distance between the first slanting surface portion 421 and the second slanting surface portion 422 is increased while being in contact with the first elastic portion 423 and the second slanting surface portion 422 pressing the slanting surface portion 421, And a second elastic portion 424 for pressing the second slanting face portion 422 by a restoring force of the second slanting face portion 422.

The first elastic portion 423 is disposed in a predetermined space while being in contact with the inner surface of the rotary portion 40 and one side of the first elastic portion 423 is in contact with the first slant surface portion 421, Is elastically deformed by compression by the first slanting face portion (421) which is moved toward the inner side face of the rotary portion (40) by the insertion portion (50) moved along the slant face between the slant face portions (422).

The second elastic portion 424 is disposed in a predetermined space with one side of the second elastic portion 424 contacting the second slant surface 422 and the other side of the second elastic portion 424 being in contact with the inner surface of the rotary portion 40, Is elastically deformed by compression by the second slanting face portion (422) which is moved toward the inner side face of the rotary portion (40) by the insertion portion (50) moved along the slant face between the second slanting face portions (422).

Here, the sum of the restoring force due to the compressive elastic deformation of the first elastic portion 423 and the restoring force due to the compressive elastic deformation of the second elastic portion 424 is the sum of the forces of the second liner R2). ≪ / RTI >

The first liner R1 is rotated by a second liner R2 slid radially outward with respect to the center axis P to increase the distance from the center axis P The magnitude of the centrifugal force acting in accordance with (2) gradually increases.

Specifically, since the magnitude of the centrifugal force is proportional to the turning radius, the magnitude of the centrifugal force applied to the first liner R1 by the second liner R2 moved radially outward from the central axis P increases.

The second liner 424 is rotated about the center axis P by a sum of a restoring force resulting from compression elastic deformation of the first elastic portion 423 and a restoring force due to compression elastic deformation of the second elastic portion 424, The insertion portion 50 is gradually slid along the first slope portion 421 and the second slope portion 422 since the magnitude of the centrifugal force applied to the first slope portion R2 or the first liner R1 becomes larger.

Here, the first liner R1 and the third liner R3 are not in contact with each other even if the insertion portion 50 can not be moved along the first slope portion 421 and the second slope portion 422 any longer.

In summary, the centrifugal force applied to the first liner R1 or the second liner R2 rotated along the central axis P gradually reduces the distance between the first liner R1 and the third liner R3 Loses.

Since the magnitude of the centrifugal force is proportional to the square of the angular velocity, the intensity of the driving motor M2 that applies the rotational force to the central axis P can be adjusted to move the second liner R2 inward in the radial direction.

In other words, if the intensity of the driving motor M2 is increased and decreased at a constant interval, the distance between the first liner R1 and the third liner R3 is increased and then decreased. Thus, Grinding of the aggregate or surface peeling can be realized.

9 and 10 are schematic views for explaining a rotating part and a second liner of a mortar peeler for producing recycled aggregate for concrete according to another embodiment of the present invention.

The mortar peeler for producing the concrete aggregate for concrete according to another embodiment of the present invention has the same constitution and effect as the mortar peeler described with reference to Figs. 1 to 8 except for the receiving portion and the inserting portion, I will explain only about wealth.

9 and 10, the receiving portion 142 of the mortar peeler according to another embodiment of the present invention includes first friction surfaces 142a and 142b which are in contact with the inserting portion 150. [

The insertion portion 150 is provided with a second friction surface 150a or 150b which is in contact with the receiving portion 142. The insertion portion 150 is provided with a first frictional surface 142a or 142b and a second frictional surface 150a or 150b, The magnitude of the acting frictional force is smaller than the magnitude of the centrifugal force acting on the rotation (2) of the central axis P.

The frictional force due to the friction between the first friction surfaces 142a and 142b and the second friction surfaces 150a and 150b is smaller than the centrifugal force of the second liner R2 rotated about the center axis P Can be the same.

In other words, the direction of the frictional force and the magnitude of the direction of the centrifugal force are opposite directions, and are forces that counteract each other. Here, if the magnitude of the centrifugal force is finer than the frictional force, the insertion portion 150 will slide along the receiving portion 142 at a slow speed.

The centrifugal force applied to the first liner R1 or the second liner R2 rotated along the central axis P gradually decreases the distance between the first liner R1 and the third liner R3 Loses.

Since the magnitude of the centrifugal force is proportional to the square of the angular velocity, the intensity of the driving motor that applies the rotational force to the central axis P can be adjusted to move the second liner R2 inward in the radial direction.

In other words, if the strength of the driving motor is increased and decreased at a constant interval, the distance between the first liner (R1) and the third liner (R3) is increased and then decreased. Thus, Or surface peeling can be realized.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be apparent to those skilled in the art that changes or modifications may fall within the scope of the appended claims.
