Abstract

<P>PROBLEM TO BE SOLVED: To provide an apparatus for crushing expanded polystyrene, in which spent expanded polystyrene is crushed so rationally that it is easily reused. <P>SOLUTION: A crusher C having a plurality of disk-shaped toothed cutters 3 fixed aslant to a columnar rotating body 1 having a shaft 2 in the center in parallel at the predetermined intervals is placed in a crushing chamber B arranged separately in the main body A of this apparatus via a bearing 5 so that one end of the shaft 2 is projected to the outside of the crushing chamber B. The crusher is rotated by a motor 6 arranged separately in the main body A via a belt 6 stretched between a pulley 4 fitted to the projected shaft 2 and another pulley 8 of the motor 6. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a foamed polystyrene crushing apparatus for rationally crushing and processing used foamed polystyrene widely used as containers and cushioning materials so that it can be easily reused.

Conventionally, most of the used polystyrene foam used as a container or a buffer material is disposed of.
At the time of disposal, it was thrown away as it was or was crushed appropriately.

However, as is well known, the polystyrene foam is lightweight but bulky, so the conveyance efficiency is poor and it can be easily crushed by hand. However, since the powder floats around, it was necessary to take measures to prevent scattering.
Moreover, in order to reuse, it had to be pulverized uniformly to some extent using a machine or the like.
The present invention uses a motor for a crushing machine in which a plurality of disc saw-like cutters are fixed to a cylindrical rotating body in an inclined manner in a crushing chamber provided in a box-shaped device body. It is an object of the present invention to provide a foamed polystyrene crushing apparatus in which the foamed polystyrene is crushed into substantially uniform strips by inserting the foamed polystyrene between the crusher and the bottom plate of the crushing chamber.

  In order to achieve the above object, the present invention provides a crusher C in which a plurality of disk saw-shaped cutters 3 are fixed to a columnar rotating body 1 having a shaft 2 at the center at a predetermined interval by inclining in parallel. Is provided in a crushing chamber B separately provided in the apparatus main body A via a bearing 5 so that one end of the shaft 2 protrudes outside the crushing chamber B, and a pulley 4 is attached to the protruded shaft 2. A pulley 8 of a motor 6 provided separately inside is configured to rotate via a belt 6.

The expanded polystyrene crusher configured as described above has the following effects.
a. The foamed polystyrene is instantaneously crushed into a substantially constant size by a cutter fixed to the rotating body in an inclined manner.
b. Since crushing is performed in the crushing chamber, styrene foam fragments and powder are hardly scattered around.
c. Since the finely crushed foamed polystyrene can be pressed and stored in a container or bag, it can be transported rationally.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an internal configuration diagram viewed from the side of the present invention, FIG. 2 is a perspective view showing the internal configuration of the present invention, FIG. 3 is a longitudinal sectional view of a crusher, and FIG. FIG. 5 and FIG. 5 are exploded views of the crusher. In FIG. 5, symbol A indicates the apparatus main body, B indicates a crushing chamber, C indicates a crusher, D indicates a storage container, and E indicates an input port.

Reference numeral 1 denotes a columnar rotating body centered on an axis 2, and the rotating body 1 is formed by fixing a plurality of disk saw-shaped cutters 3 at a predetermined interval and tilting at the same angle.
As shown in FIG. 5, the cutter 3 is provided with a rotating body 1 whose inner surface is cut in an inclined manner on both sides, and is sandwiched between each of a plurality of rotating bodies 1 whose both sides are cut in an inclined manner. Even if the cutter is damaged, it is only necessary to replace the damaged cutter.
The rotating body 1 and the cutter 3 can be formed integrally, but in this case, even if one cutter is broken, the entire crusher C must be replaced, which is uneconomical.

  A pulley 4 is attached to one end of the shaft 2, and a belt 6 a is interposed between pulleys 8 of a separately provided motor 6, and the crusher C is rotated by the rotation of the motor 6.

  Reference numeral 5 denotes a bearing that supports the shaft 2 of the crusher C provided in the crushing chamber B, and is fixed to the bottom plate 9 of the apparatus main body A.

  Although the motor 6 is provided inside the apparatus main body but is provided outside the crushing chamber B and is fixed to the bottom plate 10, the motor 6 is not damaged by the polystyrene powder or particles generated in the crushing chamber.

  9 is a receiving plate provided along the lower part of the crusher C. The foamed polystyrene introduced from the insertion port E is crushed between the cutter 3 and the receiving plate 9, and the crushed foamed polystyrene falls from the passage hole 9a. It is accommodated in a storage container D installed below from a drop hole 10a provided in the bottom plate 10 below.

When the present invention configured as described above is actually used, it is as follows.
When the unnecessary polystyrene foam is introduced from the inlet, the polystyrene foam introduced is tilted and is finely crushed by a cutter and a receiving plate of a crusher that rotates in a swinging state.
In addition, the polystyrene foam that has been once introduced from the inlet is completely crushed inside the isolated crushing chamber and dropped into the lower container and accommodated.
