  : The configuration of the present invention will be described.

  1 is a casing main body provided with a hopper 2 for charging crushed waste material W on the base end side 100 and a converging section 3 on the front end side 101. A cylindrical casing 5 having the above is continuously provided. And the casing A of this invention is formed by providing the continuous cylinder part 6 in this continuous location. The casing A is attached to the base B via a frame C. A rotating shaft 8 provided with a screw 7 is mounted on the casing A. The screw 7 has a form according to the casing A, and gradually decreases in diameter toward the converging part 3, and the converging part 3 The minimum. The rotary shaft 8 is cantilevered and is supported via bearings 9 and 9 provided at intervals. Further, the free end 800 of the rotary shaft 8 reaches the substantially front end opening 500 of the cylindrical casing 5, and slightly inside thereof controls the discharge speed of the compressed crushing waste material W1 and / or deposits on the discharge side (protrusion) (10 discharge side) Protrusions 10 are provided for the purpose of avoidance. Further, the protruding portion 10 can contribute to melting and / or shape fixing of the peripheral portion W2 (outer peripheral surface) by pressing the peripheral portion W2 of the compressed crushing waste material W1 to the cylindrical casing 5. Further, it has been found that it is useful for suppressing shape collapse, rupture and the like that are likely to occur after discharging from the opening 500. Therefore, the shape of the protrusion 10 is important, and according to the inventor's experience, the shape of the protrusion 10 is ideal as shown in FIGS. 4 and 5, and at least the above-mentioned effects have been confirmed. . In particular, a shape having a small approximate central annular shape shown in FIG. 5 was ideal. The reason for this is that the pressure crushing waste material W1 is gently pressed and expanded using the supply side slope 1000, and then the top surface 1001 (annular form) is used to press and / or This is because fixation of the melted shape of the pressed portion (pressed portion) can be achieved, and stability of the shape and / or explosion prevention after discharge can be avoided. Then, by using the slope 1002 on the final discharge side, the molten surface portion W3 is smoothly separated from the casing A, and the peripheral portion W2 is already melted (molten surface portion W3), and the compressed crushing waste material W1 existing inside Thus, it is possible to prevent the explosion after the discharge, etc. As long as the above object can be achieved, the projecting portion 10 is not limited to this example, and the same effect can be expected even in a spherical shape, egg shape, square shape, or the like. In this way, for example, the molded and recycled waste material Wn is formed in which the peripheral portion W2 is the molten surface portion W3 and the core portion is the compression crushing waste material W1 (see FIG. 7).

  In this example, a wheel 501 is arranged at the lower end of the cylindrical casing 5 so that the wheel can be moved. Through this movement, detachment from the casing body 1, replacement of the protruding portion 10, cleaning and clogging (crosslinking) of the casing A, or maintenance of other equipment is performed. The cylindrical casing 5 has a structure installed on a movable base D having a base end connected to the base B, and can move on the movable base D. The movable base D includes a wheel 11 and an adjuster means 12, and has a structure capable of adjusting the height of its free end. Using this height adjustment, the cylindrical casing 5 is inclined S (see FIG. 8). As a result, for example, a biased cross-section opening cylindrical portion is formed between the inner peripheral surface 502 of the cylindrical casing 5 and the melted surface portion W3 and / or compression crushing waste material W1 (molded and recycled waste material Wn), and the molded and recycled waste material Wn. A twist in the longitudinal direction is generated, such as the contact of one inner peripheral surface 502 or the separation of the other inner peripheral surface 502 of the molded recycled waste material Wn, and the clogging of the cylindrical casing 5 is eliminated. In particular, since the protrusion 10 is noticeably twisted, clogging can be eliminated and explosion prevention can be avoided.

  Further, a bulging inner peripheral surface 600 whose center bulges to the maximum is formed on the inner peripheral surface of the continuous cylinder portion 6, and the outer peripheral surface of the initial molded recycled waste material Wn is pressed and the core portion is compressed. The entire flow is secured through the speed regulation of crushing waste material W1. Further, it contributes to melting of the outer peripheral surface (generation of the melted surface portion W3).

  In the figure, 20 is a heater, 21 is a drive unit provided with a motor, a speed reducer, and the like, and 22 is a power transmission unit. Reference numeral 23 denotes a conveying roller.

  The casing body 1 is detachably installed on the frame C of the base B. The cylindrical casing 5 is detachably installed on a movable carriage 504 having wheels 501.

  Next, an example of generating the molded recycled waste material Wn from the crushed waste material W will be described. The crushed waste material W (such as shredder-dust) introduced into the hopper 2 is sequentially discharged through the screw 7 provided in the casing body 1. The crushed waste material W is collected at the core portion, and the peripheral portion W2 is melted. Then, the peripheral portion W2 is melted through the heater 20 provided in the converging portion 3 to produce the compression crushing waste material W1. Thereafter, the cylindrical casing 5 is reached, the melting of the peripheral portion W2 proceeds sequentially, and the core portion is formed of the compression crushing waste material W1. Then, after passing through the protruding portion 10, it becomes a finished product, and the molded recycled waste material Wn is molded. The molded recycled waste material Wn is cooled and hardened by the water-cooling jacket portion 4 and then sent to a predetermined location via the transport roller 23. Therefore, this molded recycled waste material Wn has a form in which the outside (outer side) is solidified by the molten surface portion W3 and the core portion is solidified by the compression crushing waste material W1. It has.

  In this example, the compression crushing waste material W1 is heated via the heater 20, and is compressed by the cylindrical casing 5 and inclined in the extrusion direction (the extrusion blade surface side is inclined in the discharge direction with respect to the supply blade surface side. In this configuration, the screw 7 is used for reliable and smooth extrusion. As an example, the fact that shredder-dust treatment can reduce weight and avoid the combustion of decomposition products or adverse effects on the outside has been supported by data at the Sakai Industrial Research Institute. . And according to this data, it is considered to have extremely useful features.
