When the dust is introduced into the barrel 15 from the port 14, it is forced into the meshing space of the screw blades 16 1 , 16 2 of the screw shafts 17 1 , 17 2 , and continues forward, that is, from the beginning to the end of the meshing space.

することはできない。 In the dust treatment process (first compression molding stage) as described above, the dust with relatively low moisture content is
The resin content mixed and present in itself softens and acts as a solidifying binder, and is molded.
Even if dust with a relatively high moisture content generates heat due to the surface pressure of the dust plate 20, the resin content mixed in the industrial waste will not reliably soften due to the low heat generation temperature.
Therefore, reliable molding cannot be achieved only by the first compression molding step.

A compression nozzle member is disposed in the shape of a substantially tapered conical cylinder with a straight cylindrical tip and a compression passage between the compressor and the outer circumferential surface, and two discharge holes facing each mandrel are formed in the tip. Therefore, the first extrusion molding part and the second extrusion molding part are formed with the die plate as a boundary.First, in the first extrusion molding part, the industrial waste is disposed of in the meshing space of the screw blades. While being forcibly kneaded, the industrial waste is transferred and compressed towards the die plate, and the resin mixed in the industrial waste is softened by the heat generated by this forced compression and discharged from multiple nozzle holes provided in the die plate. In the second extrusion molding section, the industrial waste discharged from the plurality of nozzle holes is forced by a spiral screw blade provided on the outer circumferential surface of the approximately tapered conical mandrel. The material is kneaded and compressed while being sent, is further compressed strongly by the compression passage formed between the outer peripheral surface of the mandrel and the approximately tapered cylindrical compression nozzle member, and is discharged through the straight portion of the discharge hole. Even if it is industrial waste such as shredded dirt from scrap cars that has a relatively high moisture content, the heat generation temperature will definitely rise and the resin component with a binder effect will definitely soften and solidify as it moves forward and is completely removed. As a result, large amounts of industrial waste can be significantly reduced in volume, which can greatly contribute to transportation, landfilling, incineration, etc.

置。1 Two screw shafts are rotatably arranged side by side in a barrel, screw blades that mesh with each other are provided on the screw shafts, and industrial waste mixed with resin is removed by the rotation of the screw shafts by the meshing of the screw blades. While being forcibly kneaded in a space, the industrial waste is transferred and compressed toward a die plate, and the resin content of the industrial waste is softened by the heat generated by the forced compression and then discharged from multiple nozzle holes provided in the die plate. In the compression molding apparatus for industrial waste, the tips of the two screw shafts are supported by the plate-shaped die plate having the plurality of nozzle holes, and are arranged to protrude from the discharge side of the die plate. , a substantially tapered conical mandrel is disposed at the tip of each screw shaft, a spiral screw blade is provided on the outer peripheral surface of each mandrel, and the die plate is arranged to cover the two mandrels. A compression nozzle member having a substantially tapered conical cylindrical shape and a straight cylindrical distal end, which has a compression passage between it and the outer circumferential surface of each mandrel, and has two discharge holes facing each mandrel at its distal end. A compression molding device for industrial waste, characterized in that it is configured by arranging.
