This invention places an induction heating coil on the outside of a duct made of cylindrical steel plate, and by supplying AC power to the coil, the duct is directly heated by electromagnetic induction, while being compressed and formed in a compression chamber. The plastic waste block is press-fitted into the heated duct which is directly connected to the compression chamber using the main cylinder, and at the same time, the pressure cylinder is pressed from the opposite side to confine the plastic waste block. After the melted layer is melted, it is further transferred by a main push cylinder to a transfer chamber directly connected to a heating duct, and after the molten layer is solidified, it is pushed outside by a transfer cylinder, making it easy to transport and handle as if the surface is coated. The aim is to provide a waste volume reduction block.

A main pushing cylinder 8 is attached to the rear of the compression chamber 1 and serves to compress and transport the plastic waste. Further, on the front side, a heating duct 4 surrounded by an induction heating coil 3 has almost the same cross-sectional shape as the compression chamber 1 and is directly connected to the induction heating coil 3 through a coil terminal 3a from an induction heating power source 11. By applying an alternating current voltage, the heating duct 4 generates Joule heat by electromagnetic induction and is heated to a target temperature.

スチツク廃棄物の減容率を高めることができる。 2 to 5 show the operation of the embodiment of the present invention, and FIG. 2 shows the state immediately before the unprocessed plastic waste 12a is introduced into the compression chamber 1 and is compressed and molded. After the compression lid 2 is closed by the lid cylinder 7, the main push cylinder 8 moves forward by one step, and the plastic waste is sealed in the heating duct 4, which has been heated by induction, as shown in FIG. While being compressed and molded, the outer periphery of the compressed and heated plastic 12b melts and becomes liquid, creating a state similar to that of a coating on the surface of the plastic waste. In this compression/forming process, pressure is also applied from the presser cylinder 9 in the opposite direction to the main presser cylinder 8, so that the plastic waste is compressed and molded on both sides of the main presser head 8a and the presser head 9a. In this way, the volume reduction rate of plastic waste can be increased by heating, compressing and molding the plastic waste while pressurizing it from both sides in the heating duct 4 with the main press cylinder 8 and the press cylinder 9. .

繰返す。 Figure 4 shows the molded plastic 1 after compression and heating.
2c shows a state in which the molded plastic 12c is cooled and solidified after being transferred to the unloading chamber 5 by the second advance of the main press cylinder and the retreat of the presser cylinder 9. FIG. 5 shows the discharge state of the molded plastic 12c, that is, the plastic block.
By moving the carry-out cylinder 10 forward, it is transferred to the carry-out port 6 on the plane of the carry-out head 10a. When this series of operations is completed, each cylinder operates in reverse, returns to the initial state as shown in FIG. 2, and repeats this process thereafter.

ともできる。 In the embodiment described above, the compression lid of the compression chamber extends over the entire length up to the point where it touches the heating duct, but if a portion of the compression chamber without a lid is provided between the compression chamber and the heating duct, the strength of the compression lid will be equal to that of the lid cylinder. The pressing force can also be reduced. At this time, the stroke of the main push cylinder should be increased. In addition, if a lid is installed at the exit of the unloading chamber, it is possible to prevent the block from expanding until it cools and solidifies.When a molten layer of a predetermined thickness is formed in the heating duct, heating is stopped and the block is discharged after cooling. If you do that, you won't need an unloading room. In this case, the induction heating coil may be formed of a water-cooled tube, or a separate cooling coil may be wound together with the heating coil and cooling water may be caused to flow therethrough for cooling.

According to this invention, only the surface layer of a large amount of compressed plastic waste is heated and melted in a heating duct almost uniformly at a set temperature by electromagnetic induction, thereby minimizing the heating energy per unit processing capacity. Since the processing temperature can be controlled arbitrarily and quickly, insufficient melting due to low temperatures and generation of harmful gases due to excessive temperature rise can be prevented.

It does not damage the equipment, and in fact, even a large amount of foreign matter does not cause any harm in the center of the plastic block, so there is no need for a device to sort out foreign matter in the previous process.

る。 In addition, the presser cylinder is advanced from the unloading chamber side and pressed from the opposite side of the main press cylinder to confine the compressed material in the coil installation area of the heating duct. It can be placed in a portion where there are no obstacles such as a transport mechanism. In other words, in order to obtain a pressing force that opposes the main pushing cylinder by using the end wall of the unloading section, a heating means must be provided in the unloading section, but the unloading mechanism gets in the way and requires induction heating. However, it is extremely difficult to arrange the heating coil. In the present invention, by providing the presser cylinder, compression heating can be performed in front of the unloading section, so the heating coil can be placed in a place where there are no obstacles.
