  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the configuration of a waste dissolution treatment apparatus according to the present invention. And a drive ball 4 including a plurality of ceramic balls 6 and a limonene solvent 7 filled in an appropriate amount in the drum 1.

  The drum 1 has a semicircular inner bottom surface 8, and in a preferred embodiment, heating means such as a heater 9 is installed along the outer bottom surface.

  A plurality of agitation shafts 5 whose front end portions rotate and move along the inner bottom surface 8 of the drum 1 are attached to the drive shaft 4 by changing the attachment angle and shifting the attachment position. In the illustrated embodiment, three stirring shafts 5 are attached at intervals of 120 degrees. Both ends of the drive shaft 4 are pivotally supported by the inner wall 3 of the drum 1, and one end portion is exposed to the outside of the drum 1 and connected to the drive means. The drive means is usually a reduction motor, but it can be driven by using wind power (wind turbine) or hydraulic power (turbine) depending on the installation location of the apparatus.

  In a preferred embodiment, a stirring blade 10 is attached to the tip of the stirring shaft 5 so as to be rotatable and movable in the axial direction of the stirring shaft 5. In order to obtain such a configuration, the stirring blade 10 is formed by attaching, for example, four blades 12 to the peripheral surface of the cylindrical body 11, and the cylindrical body 11 is loosely fitted to the tip of the stirring shaft 5. A cylindrical body 11, in other words, a spring 13 acting so as to constantly urge the stirring blade 10 toward the tip end is assembled on the stirring shaft 5.

  The stirrer blade 10 disposed at a position close to the inner wall 3 of the drum 1 at both ends of the drive shaft 4 is narrowed at the tip side to form a relief portion 14 for the ceramic ball 6. The escape portion 14 prevents the ceramic ball 6 from being clogged between the inner wall 3 and the inner bottom surface 8 by causing the ceramic ball 6 to escape when the stirring blade 10 revolves around the drive shaft 4. It is provided for this purpose.

  In addition, a configuration in which the stirring blade 10 is rotatably attached to the stirring shaft 5 and movably attached in the axial direction of the stirring shaft 5, and is always urged toward the front end side by the spring 13 is also used. This contributes to preventing clogging of the ceramic balls 6 between the inner wall 3 and the inner bottom surface 8. That is, when the ceramic ball 6 is sandwiched between the stirring blade 10 and the inner wall 3 and the inner bottom surface 8 and a load is applied to the stirring blade 10, the stirring blade 10 rotates to avoid the load, or the stirring shaft 10 It can operate to move in the direction of the 5 axis.

  As the ceramic balls 6, those having a diameter of about 10 to 12 mm are usually used, but the diameters do not need to be uniform, and various sizes may be mixed.

  Limonene is a safe solvent collected from the peels of citrus fruits such as oranges, and its structure resembles styrene monomer (monomer), so it is known to have the property of dissolving styrene resin (polystyrene). It is what. The limonene solvent 7 is usually filled to such an extent that the ceramic balls 6 group are immersed.

  In order to describe the operation of the waste dissolution treatment apparatus according to the present invention having the above-described configuration, first, the drive shaft 4 is driven to rotate by operating the speed reduction motor, and the ceramic balls 6 and the limonene solvent 7 are driven by each stirring shaft 5. And stir. Since the stirring blades 10 are respectively attached to the stirring shaft 5 so as to be rotatable and movable in the axial direction, the ceramic balls 6 and the limonene solvent 7 can be stirred almost uniformly without difficulty. The rotation of the drive shaft 4 is, for example, about 2 rotations / minute.

  In the above state, if waste containing polystyrene waste is put into the drum 1 from the inlet 2, the waste is mixed with the ceramic balls 6 and the limonene solvent 7 and stirred, and is gradually dissolved by the limonene solvent and disappears. .

  As described above, in the waste dissolution treatment apparatus according to the present invention, the waste is simply stirred in by the stirring shaft 5 (stirring blade 10) while being mixed with the ceramic balls 6 and the limonene solvent 7 simply by charging from the charging port 2. Since it is dissolved, it is possible to automatically and hygienically treat wastes that are difficult to process without putting your hands on them.
