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 starting the melting process of the waste plastic P, first, the operator operates the operation panel 17 to operate the motors 32, 60, 70, the blowers 92, 110, and the burner 1
After turning on the power of the crusher 12, the hopper lid 50 of the crusher 12 is opened, and a waste plastic P such as styrofoam, polyethylene, polyvinyl chloride, or polypropylene is supplied to the inlet 46.
From the crusher 12. As a result, the motor 3
These waste plastics P are sandwiched between the rotary blade 20 and the fixed blade 22 rotated by the rotary cutter 2 to be roughly crushed.

That is, in the crusher 12, the body 18 is configured to be low, and the inlet 46 for 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 laterally fed 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
Where it is naturally cooled by air and solidified.

When the waste plastic P accumulates in the container 114, the worker puts the door 116 attached to the outlet 115 of the cooling unit 78 in a state where the upper surface of the loading platform 202 and the lifting platform 128 are aligned. Is opened, the container 114 is taken out, the container 114 on which the waste plastic P is collected is put on the elevating table 128, the motor 136 is rotated, and the motor 13
The wire 137 is sent out from the drum 136A of No. 6.

As a result, the roller supporting member 130 is guided by the guide member 124, and the elevator 128 descends, and the elevator 128 descends to the vicinity of the ground G.

Then, the operator lowers the container 114 on the elevator 128 onto the ground G, and moves to the rear side of the truck 200, for example, by dragging on the ground G. Thereafter, the elevator 1 of the elevator 146 attached to the shelf 140
58 and the guide member 154 are rotated and opened, and the elevator 158 is lowered by the motor 166 to a position near the ground G.
14 is put on this elevator 158.

Further, the motor 166 of the elevator 146 is rotated, and the wire 166A is moved from the drum 166A of the motor 166.
Wind up 7.

As a result, the mounting plate member 160 is
4, the elevator 158 is raised. Then, it stops at a position corresponding to the empty storage plate 140A, and the worker moves to the shelf 140.

On the other hand, separately from this, an empty container 114 is put into the melting machine 114 through an outlet 115, and the waste plastic P is stored in the container 114. When a certain amount of waste plastic P is accumulated, it is stored in the shelf 140 using the elevators 122 and 146 in the same manner as described above. Then, the above operation is repeated.

Therefore, even when a large amount of waste plastic P is processed, it is possible to safely move the waste plastic P with minimum human power without manually raising and lowering dangerous waste plastic P which is heavy and hot at high temperatures. Can be stored.

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 disposed 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.
