Abstract

When industrial waste is transported and compressed toward a die plate while being forcibly kneaded in the meshing space of a screw blade, the moisture contained in the industrial waste is removed and separated from the solid matter. Moisture is drained from the drain hole, and combustion efficiency can be improved when the solidified product is used as fuel, and industrial waste can be effectively used as fuel with good combustion efficiency.
In a barrel 1, two screw shafts 2 and 2 are rotatably arranged in parallel, and industrial waste W in which resin components are mixed by the rotation of the screw shaft is disposed in the meshing space R of the screw blades 2a and 2a. While being forcibly kneaded, it is transferred and compressed toward the die plate 3 and discharged from the plurality of nozzle holes 4, 4. Therefore, the drain hole 5 is provided in the outer peripheral wall 1a of the barrel.

  However, in the case of such a conventional structure, for example, in the case of industrial waste containing a lot of moisture such as paper sludge (pulper slag, screen slag, etc.) generated in the paperboard industry, the moisture content of the compression molded solidified product For example, when such a solidified molded product is used as a fuel, there is a disadvantage that the combustion efficiency may be lowered.

  SUMMARY OF THE INVENTION The present invention has been made to solve the above disadvantages. Among the present inventions, the invention according to claim 1 is characterized in that two screw shafts are rotatably arranged in parallel in the barrel, and the screw is provided. Screw shafts meshing with each other are provided on the shaft, and industrial waste mixed with resin by rotation of the screw shaft is transported and compressed toward the die plate while forcibly kneading in the meshing space of the screw blades. In the compression molding apparatus for industrial waste that is discharged from a plurality of nozzle holes provided in the die plate in a state in which the resin content of the industrial waste is softened by heat generated by the water, the outer peripheral wall portion of the barrel is drained. An industrial waste compression molding apparatus characterized by comprising holes.

  According to a second aspect of the present invention, a plurality of through holes are formed in the outer peripheral wall portion of the barrel, an inner wall material is fixed to the inner surface of the outer peripheral wall portion of the barrel, and the through hole is formed in the inner wall material. A plurality of the small-diameter water drainage holes communicating with each other are formed.

  As described above, according to the present invention, industrial waste is put into the barrel, and the industrial waste is forcedly kneaded in the meshing space of the screw blades toward the die plate. It is transferred and compressed, and the resin component of industrial waste is softened by the heat generated by this forced compression, and is continuously extruded and discharged from a plurality of nozzle holes provided in the die plate, and is solidified and molded. At the time, since the drain hole is disposed in the outer peripheral wall portion of the barrel, the industrial waste is industrially discarded when it is transported and compressed toward the die plate while being forcibly kneaded in the meshing space of the screw blade. The water contained in the product is removed, and the water separated from the solid material is drained from the drain hole. For this reason, the moisture content of the solidified molded product discharged from the nozzle hole and solidified is low, The solidified molded product can be improved combustion efficiency when used as a fuel, it is possible to effectively use the industrial waste as a good fuel for combustion efficiency.

  According to a second aspect of the present invention, a plurality of through holes are formed in the outer peripheral wall portion of the barrel, an inner wall material is fixed to the inner surface of the outer peripheral wall portion of the barrel, and the through hole is formed in the inner wall material. A plurality of small-diameter drainage holes communicating with the pipe are formed, so that only possible removal of moisture from industrial waste kneaded and compressed in the barrel through the small-diameter drainage holes is performed. Can do.

  1 to 7 show an embodiment of the present invention. Reference numeral 1 denotes a barrel, the barrel 1 is mounted and fixed on the machine base B, and an inlet T is formed on the side upper portion of the barrel 1. Two screw shafts 2 and 2 are rotatably arranged in parallel, screw blades 2a and 2a meshing with the screw shafts 2 and 2 are provided, an electric motor M is provided on the machine base B, and a gear mechanism H is provided. The gear mechanism H and the screw shafts 2 and 2 are connected, and the gear mechanism H and the electric motor M are connected. The rotation of the electric motor M is transmitted to the two screw shafts 2 and 2 by the gear mechanism H. The industrial waste W in which the resin component is mixed by the rotation of the screw shafts 2 and 2 is transported and compressed toward the die plate 3 while forcibly kneading in the meshing space R of the screw blades 2a and 2a. Industrial waste W due to heat generation It is configured to be discharged from the nozzle holes 4, 4 ... of a plurality of nozzles 4a, 4a ... provided in the die plate 3 in a state where the resin component is softened.

  5 is a drain hole, and in this case, a plurality of through holes 5a, 5a,... Are formed in the outer peripheral wall portion of the barrel 1 as shown in FIGS. The inner wall material 1b fixed to the inner surface of the portion 1a is formed, the drainage basin portion F and the drainage port portion E are provided in the machine base B, and the small-diameter water drain is connected to the inner wall material 1b through the through holes 5a and 5a. A plurality of holes 5 are formed, and the inner wall material 1b is fixed to the outer peripheral wall portion 1a of the barrel 1 by welding.
