Herein with reference to the accompanying drawings, preferred embodiments of the present invention in more detail as follows.

1 is a front view showing a compression type reduction apparatus according to the present invention.

Compression reduction apparatus 100 of the present invention can increase the processing efficiency by separating and installing the shredding unit 10 and the compression chamber 30 as shown in Figure 1 when the capacity is large according to the capacity of the waste styrofoam to be compressed In case of small capacity, it can be connected in one piece.

The crushing unit 10 is composed of a hopper 12 for throwing waste styrofoam, and a primary crushing roll 14 and a secondary crushing roll 16 for crushing the injected waste styrofoam over the first and second.

The hopper 12, the size of the waste styrofoam to be injected has a box size of the hexahedron, it is preferable to install a wide area that can accommodate this.

In addition, the primary crushing roll 14 installed directly below the hopper 12 is installed so as to crush the size of the injected waste styrofoam thick, so that the injected waste styrofoam is first crushed by rotating at an appropriate rotational speed.

On the contrary, under the primary crushing roll 14, the secondary crushing roll 16 is installed, and the rotational speed is applied at a higher speed than the primary crushing roll 14, so that the primary crushed waste styrofoam is Allow to crush finely.

Therefore, the box-size waste styrofoam injected through the hopper 12 is crushed to a medium size in the primary crushing roll 14, and then finely crushed while passing through the secondary crushing roll 16, the waste styrofoam of Crushing process is completed.

The finely crushed waste styrofoam is transferred to the compression chamber to be compressed, and the configuration of the compression unit including the compression chamber will be described with reference to FIGS. 1 to 5.

The crushed waste styrofoam is introduced into the compression chamber 30 through the transfer unit 20, and the transfer unit 20 is located at the bottom of the hopper 22 for crushed waste styrofoam input. Screw conveyor 24.

The screw conveyor 24 is installed in the longitudinal direction, the discharge portion is connected to the inside of the compression chamber 30 by the inclined tube, bar styrofoam introduced through the hopper 22 at a predetermined speed When the horizontal transfer in the longitudinal direction while maintaining the crushed waste styrofoam exiting the screw conveyor 24 is accumulated from the bottom surface of the compression chamber (30).

Here, the structure of the compression part which concerns on this invention divided into a compression chamber, a 1st compression part, and a 2nd compression part is demonstrated in detail.

The compression chamber 30 may be selectively installed in a large or small volume according to the capacity of the waste styrofoam to be compressed.

In addition, the first compression unit 40 is a vertical compression cylinder 42 mounted on the upper end of the compression chamber 30, and a vertical pressure plate which is driven in the vertical direction together with the drive of the vertical compression cylinder 42 ( 44).

More specifically, the vertical compression cylinder 42 is mounted to the upper center portion of the compression chamber 30, the vertical pressure plate 44 is integrally mounted to the piston shaft of the vertical compression cylinder 42, wherein The vertical pressure plate 44 of the compression chamber 30 is formed to be substantially the same as the width of the compression chamber 30, is located on the inner surface of the upper end of the compression chamber 30, the reciprocating drive in the vertical direction along with the drive of the vertical compression cylinder 42 It is done.

In particular, the lower end of the guide rod 46 passing through the upper end of the compression chamber 30 is integrally connected to both upper surfaces of the vertical pressure plate 44, the guide rod 46 is the compression chamber 30 Longer than the vertical length of, the upper end of the up and down stroke sensor 48 is installed.

Therefore, the guide rod 46 moves vertically together during vertical movement of the vertical pressure plate 44, thereby acting as a guide during vertical movement of the vertical pressure plate 44, and vertically reciprocating the vertical pressure plate 44. It will help you maintain the uprightness of your workout.

Accordingly, the crushed waste styrofoam accumulated in the compression chamber 30 is compressed by the pressing force of the vertical pressure plate 44 to drive in the downward direction, the vertical stroke length of the vertical pressure plate 44 (for example, top dead center) And the bottom dead center position) by detecting and controlling the up and down stroke detection sensor 48 installed at the top of the guide rod 46, so that the primary compression amount of the closed styrofoam can be constantly adjusted.

At this time, the position of the vertical pressurizing plate 44 of the vertical compression cylinder 42 continues to be located at the bottom dead center. At this time, the driving of the second compression unit 50 is described as follows.

The second compression unit 50 is integrally connected to the piston shaft of the horizontal compression cylinder 52 and the horizontal compression cylinder 52 is fixed to the lower end of the compression chamber 30 by using a predetermined frame. It is formed of a horizontal pressure plate 54 reciprocally driven in the left and right directions.

In particular, the rear left end of the horizontal compression cylinder 52 is provided with three left and right stroke detection sensors 56 to control the position of the horizontal pressing plate 54 in two stages.

Accordingly, while the vertical pressure plate 44 is located at the bottom dead center and the horizontal styrofoam is first compressed, the horizontal pressure plate 54 is driven in the horizontal direction along with the driving of the horizontal compression cylinder 52. The second compression bar, wherein the left and right stroke detection sensor 56 controls the left and right stroke of the horizontal pressure plate (54).

The control is such that the horizontal pressure plate 54 first moves forward, stops at an intermediate point, and then moves backward to move forward from the initial position to the final position at once.

That is, the three left and right stroke detection sensors 56 control the stroke position of the horizontal pressure plate, the time when the horizontal pressure plate 54 advances to the intermediate position and its position, and the time and the position to return to the original position again, Finally, it controls the timing and position of advancing from the original position to the final position at once.

The reason why the horizontal pressure plate 54 performs the compression twice is to give the time that the air compressed therein easily escapes to the outside together with the compression of the waste styrofoam.

The performance of the first and second compression as described above and the vibrations and stresses thereof are easily buffered by the support structure supporting the entire compression chamber 30, that is, the support supporting the bottom of the compression chamber 30. Vibration and stress due to the first and second compression are easily buffered by the frame 96 and the support 98 supporting the entire compression chamber while being in close contact with the bottom surface of the support frame 96. .

As such, after the waste styrofoam is compressed in the first and second stages, the waste styrofoam is discharged into the stagnation chamber through the outlet formed at the position opposite to the horizontal compression cylinder 52.

The discharge port is formed by the tapered frame 60. Since the inner surface of the tapered frame 60 has a cross-sectional structure that narrows toward the outside, the primary and secondary compressed waste styrofoam are formed of the tapered frame 60. As you exit the interior, third compression occurs.

More specifically, the primary and secondary compressed waste styrofoam are subjected to the tertiary compression molded to a certain size while passing through the tapered frame 60, and when the final compressed waste styrofoam is to be changed, It is possible to replace the taper frame 60 of another specification with a large or small amount of taper.

That is, in order to obtain the compression density of the previously designated waste styrofoam at the time of design, by adjusting the taper amount of the tapered frame 60 and tertiary compression, the compressed waste styrofoam of the specified density can be discharged to the stagnation chamber.

Herein, the structure and its operation of the stagnation chamber will be described with reference to FIGS. 2 to 5.

The stagnation chamber is composed of a first stagnation chamber 70 and a second stagnation chamber 80, so that the air compressed together in the compressed waste styrofoam can be easily discharged to the outside, the compression in the compressed state It keeps the density and shape as it is.

Looking at the configuration of the first stagnation chamber 70, first, the upper plate 72, the lower plate 76 and both side plate 74 is mounted to the outlet of the tapered frame 60 by a hinge.

In addition, both side plates 74 are in close contact with the side surfaces of the upper plate 72 and the lower plate 76, and are fastened by a plurality of push adjusting bolts 92, and in particular, the lower plate 76 and both side plates 74. A plurality of air outlets 94 are formed through.

In addition, at the upper end portions of both side plates 74 of the first stagnation chamber 70, a fitting piece 77 having a right angle shape occupies a position higher than that of the upper plate 72 and is integrally formed, and the fitting piece ( 77, the pressing plate 78 of a predetermined weight to press the upper plate 72 is fitted.

On the other hand, the upper plate 82 of the second stagnation chamber 80 is a bar of a predetermined length is integrally connected in a grid shape, it is placed on the upper surface of the waste styrofoam passing through the second stagnation chamber 80 as it is.

Similarly, a pressing plate 88 is fitted to the fitting piece 87 so as to press the grid-shaped upper plate 82, and a plurality of air outlets 94 are provided at the lower plate 86 and both side plates 84. Is formed to penetrate through.

Herein, the operation of the first and second retention chambers having the above configuration will be described in more detail.

The waste styrofoam exiting the tapered frame 60 passes through the interior of the first stagnation chamber 70 while maintaining its compressed shape. At this time, the air compressed together with the compressed waste styrofoam is combined with the first stagnation chamber. It is discharged through a plurality of air outlets 94 formed in the lower plate 76 and the both side plate 74 of the 70, accordingly, the waste styrofoam is to maintain the specified compression density and shape as it is.

On the other hand, by slightly releasing the pressure adjustment bolt 92 is fastened to both sides of the plate 74 of the first stagnation chamber (70) and by making the internal cross-sectional area of the first stagnation chamber slightly different, the first stagnation The discharge pressure of the waste styrofoam passing through the seal 70 can be easily adjusted.

In addition, by inserting the pressing plate 78 into the fitting piece 77 formed integrally on each side plate 74 of the first stagnation chamber 70, the upper plate 72 can be pressed, 1 by blocking the repulsive force of the compressed waste styrofoam passing through the interior of the stagnation chamber 70, it is possible to maintain the compressed state of the waste styrofoam.

As such, the waste styrofoam exiting the first stagnation chamber 70 is successively passed through the second stagnation chamber 80, and thus the compressed air in the waste styrofoam exits from the first stagnation chamber 70. However, the remaining amount of the remaining compressed air escapes while passing through the second stagnation chamber 80, and thus the waste styrofoam is more easily maintained at the designated compression density and shape.

That is, the remaining amount of the remaining compressed air escapes through the space between the lattice-shaped upper plate 82 of the second stagnation chamber 80 and the air outlet 94 formed in both side plates 84 and the lower plate 86. .

Similarly, the pressing plate 88 is fitted to the fitting piece 87 integrally formed on both side plates 84 of the second stagnation chamber 80, and the grid top plate 82 is pressed. 2 by blocking the repulsive force of the compressed waste styrofoam passing through the interior of the stagnation chamber 80, it is possible to maintain the final compressed state of the waste styrofoam.

On the other hand, by changing the length of the first stagnation chamber 70 and the second stagnation chamber 80, it is possible to adjust the discharge pressure and the compressed state of the waste styrofoam.

As described above, according to the compression-type reduction apparatus according to the present invention, by compressing the waste styrofoam having a large porosity to minimize the volume, there is an advantage that can be recycled and recycled in terms of environmentally friendly.
