Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a compression and solidification device for compressing and solidifying a processed material obtained by crushing waste plastic and various other waste materials.

[0002]

[Prior art]

 Waste plastic and other various wastes are bulky as they are. In particular, waste plastics are difficult to incinerate.Therefore, there is a method in which they are compressed using a solidification device, melted by heating due to natural heat or electric heat, and extruded from a nozzle or die to form a solid material of an appropriate size. It came to be implemented.

[0003]

[Problems to be solved by the device]

 In order to put a processed product such as waste plastic into the above-mentioned compressor to perform compression processing, it is necessary to crush the recovered processed product into an appropriate size by a crusher.

The crushed processed product is compressed and melted by the solidifying screw in the solidifying casing of the solidifying device and pushed out from the discharge port through the cone portion at the lower end. There was a problem that the processing power was lowered due to the rotation. In addition, since the heater is conventionally attached to the outside of the cone, the heating effect of the processed material is not good.

An object of the present invention is to provide a device capable of preventing co-rotation in a cone and effectively heating a processed material in the cone in order to solve the problems of the conventional compression-solidifying device as described above. Is.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, this invention is a compression solidification consisting of a solidification casing provided with a solidification screw that pushes down the processed material crushed by a crusher while compressing it, and a cone part provided at the lower end of the solidification casing. We have improved the system and adopted a configuration in which a protrusion is provided inside the cone to prevent co-rotation of the processed material, or a heater is provided inside the protrusion.

[0007]

[Action]

 In the above apparatus, the processed product extruded from the solidifying casing to the cone portion by the solidifying screw is efficiently kneaded while being prevented from co-rotating with the screw by the protrusions and extruded from the discharge port. At that time, if the object to be processed is heated by the projection heated by the built-in heater, the processing efficiency is further improved.

【Example】

 In FIG. 1, reference numeral 1 is a frame of a machine on which a crushing casing 3 having a charging hopper 2 is fixed laterally. Although not shown, a rotary body is arranged in the casing 3, and a rotary blade is provided on the outer circumference of the rotary body, which is driven by the motor 4.

Reference numeral 5 denotes a vertical solidifying casing fixed to the frame 1 so as to be positioned below the front portion of the crushing casing 3, and the crushing casing 3 and the solidifying casing 5 are a supply casing 6. A supply screw 7 is provided which is in communication with the casing and is driven by appropriate driving means in the casing. Further, 9 is a hopper for supplying the already crushed processed material into the supply casing 6.

In FIG. 2, reference numeral 10 denotes a vertical rotation shaft provided in the center of the solidifying casing 5, which is driven by a motor 12 on a support 11 fixed on the frame 1. The lower portion of the solidifying casing 5 serves as a cone portion 13 as shown in FIGS. 1 and 2, and the lower end thereof serves as a discharge port 14. Further, the rotating shaft 10 is provided with a solidifying screw 15.

The cone portion 13 includes an upper cone 16 and a lower cone 17, and a plurality of protrusions 20 are provided on the inner circumference of the upper cone 16. As shown in FIG. 3, the protrusion 20 has a chevron-shaped cross section and is a vertical protrusion. However, other arbitrary shapes are possible. In some cases, each of the protrusions 20 is hollow and a heater such as electric heat is incorporated therein.

In this embodiment, the processed material that has entered the solidifying casing 5 from the supply casing 6 is pushed into the cone portion 13 while being kneaded by the solidifying screw 15.

In the upper cone 16 of the cone portion 13, since the rotation of the processed material is blocked by the protrusion 20, the kneading action by the screw 15 can be sufficiently performed. By incorporating a heater in the protrusion 20, the processed material is sufficiently heated, kneaded, and discharged from the discharge port 14.

[0014]

【effect】

 According to this invention, since the plurality of protrusions are provided in the cone portion at the lower end of the solidifying casing as described above, the processed material kneaded by the rotation of the screw and pushed into the cone portion does not rotate together with the screw. . Therefore, the kneading action can be sufficiently performed, and the processing capacity is improved.

Further, when the protrusion is provided with a heater, the heat transfer efficiency to the object to be processed is improved as compared with the case where the protrusion is provided with an external heater.
