The temperature and amount of the hot air can be quickly adjusted so as to increase the efficiency of the processing operation.

Next, the operation of this embodiment will be described. By moving together with the truck 200, the waste plastic processing apparatus 10 having the above-described structure can sequentially collect waste plastics P scattered in various places and can immediately perform melting processing.

Here, when the melting process of the waste plastic P is started, first, the operator operates the operation panel 17 to operate the motors 32, 60, 70, the blowers 92, 110, and the burner 1
08, etc., the hopper lid 50 of the crusher 12 is opened, and waste plastic P such as styrene foam, polyethylene, polyvinyl chloride, polypropylene, etc. To As a result, the rotary blade 2 rotated by the motor 32
These waste plastics P are sandwiched between the zero and the fixed blade 22 to be crushed.

That is, in the crusher 12, the body 18 is configured to be low, and the input port 46 of the waste plastic P is also provided in the body 1.
8, the waste plastic P which is heavy and bulky can be easily put into the machine body 18 and the workability is improved. When the waste plastic P is charged, the hopper lid 50
Is turned to open the slot 46, and the slot is thrown into the body 18 through the slot 46. Here, since the side plate 54 is erected on the hopper lid 50, the waste plastic P put into the insertion port 46 while being placed on the hopper lid 50 does not fall off, and the loading operation is facilitated. .

After the waste plastic P is loaded, the hopper lid 50 is turned again to close the loading port 46, and the cutter 24 is operated by operating the operation panel 17. When the cutter 24 operates, the rotating blade 20 rotated by the motor 32 meshes with the fixed blade 22, so that the waste plastic P which is thrown in and slides down along the sink plate 42 is sandwiched and roughly crushed. The crushed waste plastic P passes through the long hole 34 of the fixed blade 22, is guided by the sink plate 42, and moves to the lateral feed screw conveyor 35 at the lower end of the sink plate 42.

The waste plastic P that has reached the lateral feed screw conveyor 35 after being crushed is conveyed to the outlet 62 of the machine body 18 by the screw conveyor 35 driven by the motor 60. The waste plastic P unloaded from the outlet 62 passes through the guide communication portion 63 and is sent to the lower end of the vertically fed screw conveyor 13.

Further, the crushed waste plastic P is
The screw 68 driven by the motor 70 conveys the screw feed conveyor 13 above the vertical feed screw conveyor 13 and drops through the shot 72 into the melter 14. In the supply part 74 and the melting furnace 94 of the melting machine 14, a predetermined amount of crushed waste plastic P is deposited.

On the other hand, in the hot air generator 16, the air is heated by the burner 108 and is turned into hot air by the blower 110. This hot air passes through the connection pipe 106 and stays in the hot air stagnation chamber 10.
4 and then from the hot air stagnation chamber 104 into the melting furnace 94. At the same time, the hot air heats the furnace wall 98 of the melting furnace 94. Therefore, the waste plastic P is melted by a direct heating action by hot air and an indirect heating action by heat transmitted through the furnace wall 98 of the melting furnace 94. The melted waste plastic P flows from the falling port 96 of the melting furnace 94 to the cooling section 78 by its own weight. At this time, the unmelted waste plastic P is caught by the stopper 112 and does not flow down to the container 114 of the cooling unit 78 until it is melted. Further, the exhaust gas such as gas generated from the waste plastic P during melting is discharged from the upper exhaust chamber 82 by the exhaust blower 110 to the melting machine 14.
Is discharged to the outside.

The waste plastic P, which has been melted and has flowed down from the falling port 96 of the melting furnace 94, is discharged from the container 114 of the cooling unit 78.
Where it is naturally cooled by air and solidified.

When the waste plastic P accumulates in the container 114, the operator opens the door 116 attached to the outlet 115 of the cooling part 78 and takes out the container 114 in the direction shown by the arrow B. .

As described above, the waste plastic processing apparatus 10
Then, by moving together with the truck 200, the waste plastics P scattered in various places can be sequentially collected and the melting process can be immediately performed. Therefore, there is no need to perform melting treatment after individually retrieving and collecting and transporting each place as in the prior art, and the workability of waste plastic treatment is extremely improved due to high mobility. In particular, even when the waste plastic P is bulky, there is no need to collect and transport the waste plastic P in a plurality of times, which is particularly effective.

Further, since the inlet 46, the outlet 115, and the operation panel 17 are all arranged and installed so as to face the left side, which is the same outer peripheral side of the truck 200, one worker is wasted. Since the work can be performed without performing any complicated operation, the work labor required for performing the processing work by the present processing apparatus 10 is significantly reduced. Note that the input port 46, the outlet 115, the operation panel 17, and the like may all be arranged so as to face the right side of the truck 200.

Next, a second embodiment of the waste plastic processing apparatus according to the present invention is shown in FIG. 5, and this embodiment will be described with reference to FIG. The same members as those described in the first embodiment are denoted by the same reference numerals, and redundant description will be omitted.

However, the crusher 12 has the same configuration as that of the first embodiment, but is installed in a different orientation so that the input port 46 faces the rear surface of the truck 200 on the right side in FIG. . Therefore, as shown by the arrow A, the waste plastic P can be introduced from the rear side.

Further, the melting machine 14 has the same structure as that of the first embodiment, but the door 116 is also attached to the rear side of the truck 200.
It is also installed in the direction facing the rear surface of the right truck 200. Therefore, as shown by the arrow B, the waste plastic P can be taken out from the rear side, and the waste plastic P melted and solidified, for example, the container 11 containing about 20 kg.
4 can be slid over the carrier 202 and removed from the melter 14.

Further, the operation panel 17 is arranged and installed in the vicinity of the rear end surface of the truck 200 so that the operation surface faces the rear surface side of the truck 200. Therefore, the operation can be performed from the direction of arrow C.

As described above, the inlet 46, the outlet 115, and the operation panel 17 are all arranged and installed so as to face the rear surface side, which is the same outer peripheral surface side of the truck 200. Thus, not only one worker can perform work without performing useless operation, but also a processing work in a narrow alley, which is difficult in the first embodiment for a wide road, becomes possible.

In the first embodiment and the second embodiment,
Hot air generator 1 from the front on the bed 202 of the truck 200
6, the melter 14 and the crusher 12 are arranged in this order. However, the arrangement is not limited to such an arrangement order. Therefore, the arrangement of the melter 14 of the chute 72 and the connection pipe 106 is also limited to these embodiments. Never.
