Fill the cylinder with the crushed waste urethane,
Compressed by two pistons to separate Freon gas remaining in urethane. This example is based on the premise that there is always a waste urethane crushed material in the crushed urethane storage hopper, and does not specifically describe a case where the amount of the waste urethane crushed becomes very small. It also does not mention the recovery of discharged volume-reduced urethane.

The compressive force is absorbed by the crushed material having elasticity and is stabilized at a certain pressure, but when there is no crushed material, that is, when only gas is compressed, the internal pressure increases as the compression proceeds, and gas leakage to the outside occurs Can be the cause. In the latter case, no consideration is given to the treatment of the discharged urethane.

ある。The crushed waste urethane enters the hopper and fills the space below the hopper. Then, the driving piston among the two pistons is driven to compress the waste urethane,
CFC gas remaining in the waste urethane is separated, one piston is operated, and the interval between both pistons is increased to discharge. At this time, the stroke of the driving piston is detected, and the compressed thickness of the waste urethane is detected. The detected thickness is compared with the arbitrarily set minimum thickness. If the thickness is larger than the minimum thickness, the above operation is repeated. If the compressed thickness of the waste urethane is smaller than the minimum thickness, the volume reduction processing device is stopped. . On the other hand, the restart signal is transmitted to the volume reduction processing device when the load current of the crushing device located upstream of the volume reduction processing device becomes higher than the value at the time of no load, and the operation starts. From this, it is possible to prevent gas leakage to the outside due to compression in a state where there is no crushed material, and it is also effective in reducing operating costs.

The compressed urethane compressed and discharged by the volume reduction processing device is sent to a collection container via a transfer device. Further, the urethane thickness at the time of compression is stored and held until collected in the collection container. On the other hand, the collection container is provided with a caster that can be moved in the transfer direction of the transfer device below the container, and is connected to a container driving piston. The amount of movement of the piston is determined by the product of the stored compressed thickness of urethane and the expansion coefficient after discharge, and the collection container moves with the movement of the piston. According to this example, the volume of the waste container can be effectively utilized without being influenced by the amount of waste urethane filled in the cylinder (the amount is large: the thickness is large, and the amount is small: the thickness is small). Urethane recovery can be simplified.

である。Next, the operation of this embodiment will be described. Crusher 1
And the waste urethane 3 collected by the sorting machine 2
And supplied by a screw feeder 7 driven by the power of a drive motor 8 in the direction of the pulverizer 5. The supplied waste urethane 3 is pulverized by a fine pulverizer 5 rotating at high speed by the power of a drive motor 6. The pulverized fine pulverized pieces 9 are stored in a tank 10 and then compressed and compressed by an airtight volume reduction processing device 11. The volume is reduced and discharged outside, and collected in the collection container 22. The operation of the volume reduction processing device 11 is as follows. The finely pulverized pieces 9 are disposed in the space of the casing 17 via the tank 10 so as to be opposed to the driving piston 13 connected to the main cylinder 12 and the driving piston 13 connected to the sub cylinder 14. It is stored between the driven pistons 15. The driving device 16 drives the main cylinder 12, and the driving piston 13 operates (moves until it reaches the position shown).
Similarly, the driven cylinder 14 is driven by the driving device 16, and the driven piston 15 is operated in the direction opposite to the driving piston 13, thereby closing the casing 17 (position in the figure). The finely crushed piece 9 is compressed and moved between the driving piston 13 and the driven piston 15.
The foamed gas and the gas between the particles held and contained in the finely crushed pieces are exhausted into the closed space (position in the figure). On this occasion,
The stroke of the driving piston 13 is detected by a distance sensor 19 fixed to the casing 17 and a reflecting plate 18 operating in synchronization with the driving piston 13. On the other hand, the distance sensor 19
Is transmitted to the control device 20 at any time.
The control device 20 compares the signal of the distance sensor 19 with a numerical value held for a certain period of time, that is, the thickness of the compression molded product 21 and the arbitrarily set minimum thickness, and determines the presence or absence of the next operation based on the result. For example, when the thickness of the compression molded product 21 is larger than the minimum thickness,
Operates to open the enclosed space (moves to the right in the figure)
Then, the driving piston 13 discards the compression molded product 21 to the outside. Thereafter, the driven piston 15 moves in a direction to seal the casing 17, while the driven piston 13
0 Move in the direction to open the lower space (left direction in the figure),
Repeat the compression / release operation. When the thickness of the compression-molded product 21 is smaller than the minimum thickness, as the next operation, the driven piston 13 moves in the direction of opening the space below the tank 10 with the driven piston 15 closing the casing 17 (in the figure). (Left direction) and stops after the main release operation is completed. Further, the restart signal is issued when the load current of the crusher 1 or the fine crusher 5 located upstream of the volume reduction processing device 11 becomes higher than the value at the time of no load, that is, when the crushing is started, the control device is activated. The volume reduction processing device 11 starts the above operation. From this, it is possible to prevent gas leakage to the outside due to compression in a state where there is no crushed material, and it is also effective in reducing operating costs.
