BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mortar peeling apparatus and a recycle aggregate producing apparatus including the same.

Domestic natural aggregates are highly likely to be depleted within 20 years, and development of alternative resources is urgent. Currently, forests and natural environments, which are 103 times larger than Yeoido area (850m ² ), are being destroyed every year in order to collect natural aggregates.

In order to solve these problems, the government has established the quality standard of recycled aggregate and is increasing the use of recycled aggregate.

On the other hand, typical applications of recycled aggregate are road construction and concrete (coarse aggregate, fine aggregate). Among them, recycled aggregate for road construction is produced by Crusher, a construction waste intermediate process. However, the recycled aggregate for concrete must be separated from the cement mass or mortar in order to satisfy the characteristics such as density, water absorption rate, and wear rate. Therefore, the recycled aggregate for concrete needs to be treated in a mortar peeling apparatus as disclosed in the following prior art documents. However, the conventional mortar peeling apparatus has a problem that the particle size of the recycled aggregate can not be controlled as desired by the producer.

FIG. 3 is a front view of a mortar peeling apparatus according to an embodiment of the present invention, FIG. 4 is a left side view of a mortar peeling apparatus according to an embodiment of the present invention, FIG. 5 is a right side view of a mortar peeling apparatus according to an embodiment of the present invention, And FIG. 6 is a plan view of a mortar peeling apparatus according to an embodiment of the present invention.

3 to 6, the mortar peeling apparatus 400 according to the present embodiment includes a plurality of protrusions and protrusions 415 spirally extending from one end to the other end on the outer circumferential surface, rotating about a predetermined axis 420, A peeling roll 410 whose diameter increases from one end to the other along the longitudinal direction of the predetermined axis 420 and a peeling roll 410 which peaks from the outer circumferential surface of the peeling roll 410 And the peeling surface 440 has a diameter increasing from one end to the other along the longitudinal direction of the predetermined axis 420 and the peeling roll 410 is peeled off from the peeling roll 410, When the peeling plate 430 is moved in the longitudinal direction of the predetermined axis 420 with respect to the peeling roll 410, the peeling plate 430 is peeled off from the peeling plate 430 440) and the peeling roll 410 is changed.

The mortar peeling apparatus 400 according to the present embodiment receives the aggregate (receives the aggregate of the second predetermined size or more (about 6 mm or more) from the second screen 300 (see FIG. 2A)), polishes the aggregate The mortar is peeled from the aggregate. Specifically, when the aggregate is put between the peeling roll 410 and the peeling plate 430, the aggregate moves in one direction by the rotation of the peeling roll 410 and the unevenness 415 formed on the outer peripheral face of the peeling roll 410 And the mortar is peeled from the aggregate. Thereafter, the ground aggregate and the peeled mortar are discharged from between the peeling roll 410 and the peeling plate 430.

The peeling roll 410 serves to crush the aggregate together with the peeling plate 430 and peel the mortar from the aggregate. Here, the peeling roll 410 is formed in a cylindrical shape as a whole, and rotates about the predetermined axis 420. At this time, unevenness 415 may extend spirally from one end to the other end on the outer circumferential surface of the peeling roll 410. As described above, the irregularities 415 extending spirally on the outer circumferential surface of the peeling roll 410 are formed and the peeling roll 410 is rotated, so that the aggregate is separated from the peeling roll 410 by the spiral- It can move naturally from one end to the other, and in the process of moving, the aggregate can be crushed and the mortar can be separated from the aggregate (see FIG. 7). Further, the diameter of the peeling roll 410 may increase from one end to the other along the longitudinal direction of the predetermined axis 420 (see FIGS. 3 and 6). That is, the peeling roll 410 may have a trapezoidal shape when viewed from the longitudinal side. On the other hand, the peeling roll 410 can be rotated by the driving unit. Here, the driving unit may be a motor, and may be connected to the peeling roll 410 by a chain or a belt to provide a driving force to the peeling roll 410.

The peeling plate 430 serves to crush the aggregate together with the peeling roll 410 and peel the mortar from the aggregate. 4 to 5), the peeling plate 430 is curved so as to surround a predetermined region of the outer circumferential surface of the peeling roll 410 (see FIG. 4 to FIG. 5) (Not shown). That is, the peeling surface 440 may be formed as a whole which surrounds the peeling roll 410 and has one side opened along the longitudinal direction of the predetermined axis 420. In addition, the peeling surface 440 increases in diameter from one end to the other along the longitudinal direction of the predetermined axis 420 (see Figs. 3 and 6). That is, the peeling surface 440 may correspond to the outer peripheral surface of the peeling roll 410. At this time, the inclination angle of the peeling surface 440 and the inclination angle of the outer circumferential surface of the peeling roll 410 can correspond to each other. The peeling roll 410 and the peeling surface 440 are spaced apart from each other by a predetermined distance. The aggregate put in at the predetermined intervals is pressed between the unevenness 415 of the rotating peeling roll 410 and the peeling surface 440, Friction is generated, and the mortar is peeled.

8 to 9, the peeling plate 430 is movable in the longitudinal direction of the predetermined axis 420 with respect to the peeling roll 410. As described above, when the peeling plate 430 moves in the longitudinal direction of the predetermined axis 420 with respect to the peeling roll 410, the distance between the peeling surface 440 and the peeling roll 410 can be changed. That is, the peeling plate 430 and the peeling roll 410 are formed so as to increase in diameter from one end to the other end of the peeling roll 430, (Movement in the longitudinal direction of the peeling roller 420) may be realized by a change in the distance between the peeling surface 440 and the peeling roll 410. Since the distance between the peeling surface 440 and the peeling roll 410 can be adjusted as described above, the particle size of the recycled aggregate can be adjusted as desired by the producer. In addition, since the interval between the peeling surface 440 and the peeling roll 410 can be reduced, it is possible to cope with the wear of the irregularities 415 formed on the outer circumferential surface of the peeling roll 410 and the like.

8, when the peeling plate 430 moves in the one end direction from the other end of the peeling roll 410 with respect to the peeling roll 410, the peeling surface 440 and the peeling roll 410 are peeled off, Can be increased. 9, when the peeling plate 430 is moved from one end of the peeling roll 410 to the other end direction with respect to the peeling roll 410, the distance between the peeling surface 440 and the peeling roll 410 Can be reduced.

As described above, in order for the peeling plate 430 to move with respect to the peeling roll 410, a frame 450 and a sliding portion 460 may be provided. Here, the frame 450 fixes the peeling roll 410, the sliding portion 460 supports the peeling plate 430, and slides with respect to the frame 450 in the longitudinal direction of the predetermined axis 420. Specifically, the frame 450 may include a base frame 451 and a support frame 453 extending upward from both sides of the base frame 451. At this time, a predetermined axis 420 may be rotatably supported on the support frame 453. Therefore, the peeling roll 410 can be fixed at a specific position with respect to the frame 450 (supporting frame 453). The sliding portion 460 has a peeling plate supporting portion 461 for directly supporting the peeling plate 430 and a roller supporting portion 461 for supporting the peeling plate supporting portion 461 and sliding on the frame 450 and the base frame 451, (463). The base frame 451 of the frame 450 is provided with a rail 455 and the roller support portion 463 of the sliding portion 460 may be provided with a roller 465 which contacts the rail 455. The sliding portion 460 can slide with respect to the frame 450 while the roller 465 of the roller supporting portion 463 rotates along the rail 455 of the base frame 451. [ On the other hand, the base frame 451 may be configured to include, for example, two H beams arranged in parallel.

More specifically, the rails 455 of the base frame 451 may extend in parallel with the longitudinal direction of the predetermined axis 420. As shown in the enlarged view of FIG. 5, the rails 455 extend in a planar form including one side and the other (for example, the rail 455 may be the upper portion of the H beam) 463 are provided with a plurality of rollers 465 so that at least one roller 465 contacts one side of the rail 455 and at least another roller 465 contacts the other side of the rail 455 have. That is, since the roller 465 of the roller supporting portion 463 contacts the both surfaces (one surface and the other surface) of the rail 455, the roller 465 of the sliding portion 460 (the roller supporting portion 463) It is possible to prevent the detachment in the vertical direction. The roller support portion 463 formed on the sliding portion 460 may extend in a 'C' shape extending around both ends of the rail 455 when viewed from the cross section. The rollers 465 are supported by a plurality of rollers 465 that contact one surface of the one end of the rail 455 and the other surface of the rail 455, Can be supported. Since the roller supporting portion 463 is formed so as to surround both ends of the rail 455, it is possible to prevent the sliding portion 460 (the roller supporting portion 463) from deviating from the rail 455 in the left-right direction .

On the other hand, a moving means 470 may be provided to move the peeling plate 430 to the peeling roll 410 (see Figs. 8 to 9). The moving means 470 is provided between the sliding portion 460 and the frame 450 so that the sliding portion 460 can be moved with respect to the frame 450 and the base frame 451. At this time, the moving means 470 is not particularly limited as long as the peeling plate 430 can linearly move with respect to the peeling roll 410, but may be, for example, a hydraulic jack.

10A, when the longitudinal direction of the predetermined axis 420 is parallel to the ground surface G, the distance from the one end to the other end along the longitudinal direction of the predetermined axis 420 is larger than that of the excavated surface 440 As the diameter increases, the peeling surface 440 has a lower height from the ground G as it goes from one end to the other end. Therefore, the charged aggregate can be moved from one end to the other end of the nipped surface 440 by gravity. That is, it is possible to realize an effect that the aggregate can be moved naturally by the inclined cleaving surface 440. However, the predetermined axis 420 does not necessarily have to be parallel to the paper surface G. For example, as shown in FIG. 10B, the frame 450 may be inclined so that the longitudinal direction of the predetermined axis 420 is And can be disposed so as to be inclined with respect to the ground G. [ Since the angle between the separation surface 440 and the ground surface G is larger than the angle between the longitudinal direction of the predetermined axis 420 and the ground surface G, the aggregate is more likely to extend from one end to the other end of the separation surface 440 Can be moved effectively.

FIG. 11 is a front view of a crusher according to an embodiment of the present invention, and FIG. 12 is a plan view of a crusher according to an embodiment of the present invention.

11 to 12, the crusher 200 according to the present embodiment includes a stationary roll 210 that rotates about a first predetermined axis 215 and is fixed at a predetermined position, And a moving roll 220 that is rotated with respect to the fixed roll 210 and movable relative to the fixed roll 210. The aggregate is rotated between the fixed roll 210 and the moving roll 220, And the like.

Basically, the crusher 200 according to the present embodiment receives an aggregate (receiving aggregate of a first predetermined size or more (about 10 mm or more) from the first screen 100 (see FIG. 2A) The aggregate is crushed between the moving roll 210 and the moving roll 220.

Here, the fixed roll 210 is formed in a generally cylindrical shape and rotates about the first predetermined axis 215. Similarly, the moving roll 220 is also formed in a generally cylindrical shape and rotates about the second predetermined axis 225. At this time, the fixed roll 210 and the moving roll 220 are arranged side by side and spaced apart by a predetermined distance. A plurality of first protrusions 213 protrude in the radial direction from the fixed roll 210 and a plurality of second protrusions 223 protrude in the radial direction from the moving roll 220 (See also Fig. At this time, a second protrusion 223 is disposed between the adjacent two first protrusions 213, and a first protrusion 213 is disposed between the adjacent two second protrusions 223. That is, the plurality of first protrusions 213 and the plurality of second protrusions 223 can be alternately arranged. Accordingly, the aggregate charged at a predetermined distance between the rotating fixed roll 210 and the moving roll 220 can be crushed by the plurality of first protrusions 213 and the plurality of second protrusions 223. Meanwhile, the stationary roll 210 and the moving roll 220 may be rotated by a driving unit. Here, the driving unit may be a motor, and may be connected to the stationary roll 210 and the moving roll 220 by a chain, a belt, or the like to provide a driving force.

Meanwhile, the fixed roll 210 is fixed at a predetermined position, and the movable roll 220 is movable with respect to the fixed roll 210. That is, the fixed roll 210 is fixed in position, and the movable roll 220 is movable in a direction approaching or away from the stationary roll 210. The fixed roll frame 233, the movable roll frame 235, the crusher frame 230, the gap adjusting means 240, and the like are provided in order to move the moving roll 220 relative to the fixed roll 210 .

Specifically, the crusher frame 230 is provided at the bottom of the crusher frame 230 to support the stationary roll frame 233, the moving roll frame 235, and the like. At this time, the stationary roll frame 233 supports the stationary roll 210 and is fixedly supported by the crusher frame 230. Further, the moving roll frame 235 supports the moving roll 220 and is movably supported by the crusher frame 230. Specifically, the movable roll frame 235 rotates in a direction perpendicular to the second predetermined axis 225 (or the first predetermined axis 215) so that the distance between the fixed roll 210 and the movable roll 220 is adjusted, It can move with respect to the frame 233. More specifically, the crusher frame 230 is provided with a crusher rail 237, and the moving roll frame 235 may be provided with a crusher roller 239 which contacts the crusher rail 237. The moving roll frame 235 can slide with respect to the crusher frame 230 while the crusher roller 239 of the moving roll frame 235 rotates along the crusher rail 237 of the crusher frame 230. [ The crusher roller 239 of the moving roll frame 235 and the crusher rail 237 of the crusher frame 230 are connected to the roller 465 of the roller support portion 463 according to the above- May be formed in the same structure as the rail 455 of the base frame 451, and a description overlapping with the mortar peeling apparatus 400 will be omitted.

On the other hand, a gap adjusting means 240 may be provided to move the moving roll 220 (movable roll frame 235) relative to the fixed roll 210 (fixed roll frame 233). The gap adjusting means 240 is provided between the moving roll frame 235 and the fixed roll frame 233 so that the moving roll frame 235 can be moved with respect to the fixed roll frame 233. [ In this case, the gap adjusting means 240 is not particularly limited as long as the movable roll frame 235 can linearly move with respect to the fixed roll frame 233, but the nut member 243 and the bolt member 245 .

Specifically, the nut member 243 can be fixed to the fixed roll frame 233. [ At this time, the bolt member 245 is fixed at one side to the moving roll frame 235 (for example, the bolt member 245 can be fixed to the moving roll frame 235 by a separate nut 247) And the other side can be screwed to the nut member 243. Therefore, when the bolt member 245 is rotated, the relative position of the bolt member 245 with respect to the nut member 243 is changed by the screwing of the bolt member 245 and the nut member 243, 235 can move with respect to the stationary roll frame 233. 13, when the bolt member 245 is rotated in one direction with respect to the nut member 243, the movable roll frame 235 is moved in the direction to approach the fixed roll frame 233 So that the distance between the moving roll 220 and the fixed roll 210 can be narrowed. 14, when the bolt member 245 is rotated in the other direction with respect to the nut member 243, the moving roll frame 235 moves in the direction away from the stationary roll frame 233, The distance between the roll 220 and the fixed roll 210 can be increased. By adjusting the distance between the moving roll 220 and the fixed roll 210, the degree of crushing of the aggregate can be controlled, and the first protrusion 213 of the fixed roll 210 and the moving roll 220 Of the second protrusion 223 of the first protrusion 223.

On the other hand, the nut member 243 is not necessarily fixed to the fixed roll frame 233 and the bolt member 245 is not necessarily fixed to the movable roll frame 235. The nut member 243 is not necessarily fixed to the movable roll frame 235 And the bolt member 245 may be fixed to the fixed roll frame 233. [ Namely, the nut member 243 is fixed to one of the fixed roll frame 233 and the movable roll frame 235, and the bolt member 245 is fixed to the fixed roll frame 233 and the movable roll frame 235 As shown in FIG.

Additionally, the moving roll 220 may be provided with an elastic means 250 for providing elasticity in the direction of the fixed roll 210. Here, the elastic means 250 may be provided between the moving roll frame 235 directly supporting the moving roll 220 and the crusher frame 230. This elastic means 250 provides the moving roll 220 with a certain elasticity in the direction of the fixed roll 210, so that it is possible to prevent the moving roll 220 from flowing heavily. For example, there is a possibility that the moving roll 220 may be arbitrarily moved due to a clearance between the nut member 243 of the gap adjusting means 240 and the bolt member 245 or unwanted loosening of the bolt member 245, By providing the elastic means 250 to provide elasticity to the moving roll 220, the flow of the moving roll 220 can be prevented in advance. On the other hand, the elastic means 250 is not particularly limited as long as it can provide elasticity to the moving roll 220, but may be, for example, a compression spring.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification or improvement is possible.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
