  : The configuration of the present invention will be described.

Reference numeral 1 denotes a casing main body provided with a hopper 2 for supplying crushed waste W on the base end side 100 and a converging section 3 on the front end side 101. The casing main body 1 includes at least a water-cooling jacket section 4 and an opening section 500. A cylindrical casing 5 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. This is the casing A are Kauketamawa rotating shaft 8 having a screw 7, the screw 7 is in a form conforming to the casing A, sequentially become smaller in diameter toward the converging section 3, a minimum of converging section 3 It becomes. The rotary shaft 8 is cantilevered and is supported via bearings 9 and 9 provided at intervals. Further, the free end 800 of the rotating shaft 8 reaches the substantially front end opening 500 of the cylindrical casing 5, and on the slightly inner side thereof, the control of the discharge speed of the compressed crushing waste material W1 and / or the accumulation (projection part) on the discharge side is performed. 10 for the purpose of avoiding the discharge side). Moreover, this protrusion part 10 can press the peripheral part W2 of the compression crushing waste material W1 to the cylindrical casing 5, and can also contribute to the melting and / or shape fixation of the said peripheral part W2 (outer peripheral surface). Further, it has been found that it is also useful for suppressing shape collapse, rupture, etc., which are likely to occur after discharging from the opening 500. Therefore, the shape of the protruding portion 10 is important. According to the inventor's experience, the shape of the protruding portion 10 is ideal as shown in FIGS. 4 and 5, and at least the above-described effects have been confirmed. . In particular, a shape having a small approximate central annular shape shown in FIG. 5 was ideal. The reason is that the compression crushing waste material W1 is gently pressed and expanded by using the supply-side inclination 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, mainly the smooth separation of the molten surface portion W3 from the casing A, the peripheral portion W2 is already melted (molten surface portion W3), and the compression crushing waste material W1 existing inside is present. Thus, it is possible to prevent the explosion after the discharge, etc. As long as the above-described object can be achieved, the projecting portion 10 is not limited to this example, and a similar effect can be expected even in a spherical shape, egg shape, square shape, or the like. In this way, for example, the molded 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 as to be movable. Through this movement, removal from the casing body 1, replacement of the protruding portion 10, cleaning and clogging (crosslinking) of the casing A, or maintenance of other devices are 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 wheels 11 and 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 the compression crushing waste material W1 (molded and recycled waste material Wn), and the molded and recycled waste material Wn. Thus, 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 molding recycled waste material Wn, and the clogging of the cylindrical casing 5 is eliminated. In particular, since a significant twist occurs in the protruding portion 10, 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 tube portion 6, and the outer peripheral surface of the initial molded recycled waste material Wn is pressed to compress the core portion. The entire flow is secured through speed regulation of the crushing waste material W1. Moreover, 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 provided with 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 a shredder-dust) introduced into the hopper 2 is sequentially discharged via a 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 while being sequentially fed toward the converging portion 3 of the casing body 1. Then, the peripheral portion W2 is melted through the heater 20 provided in the convergent 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. And after passing the protrusion part 10, it becomes a finished product and the shaping | molding reproduction | regeneration waste material Wn is shape | molded. The molding 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, the molding recycle waste material Wn has a form in which the outside (outside) 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 through 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. The configuration is such that reliable and smooth extrusion is achieved by the screw 7. As an example, the fact that shredder-dust treatment can reduce weight, avoid the combustion of decomposition products, or adverse effects on the outside has been supported by data at Sakai Industrial Research Institute. . And according to this data, it is considered to have extremely useful features.
