Therefore, even if it softens and melts, it will not stick to the furnace wall, and as the specific gravity increases due to softening and melting, it will gradually escape from the floating state and fall to the discharge port side. Therefore, it is possible to prevent clogging caused by waste plastics that do not soften and melt as much as possible. Details,
To explain in detail, 1 is a blower for taking in outside air; 1 is a hot air generator 1 equipped with an oil burner 2; Kj is connected to the main furnace 3 via an intake pipe 4. A known deodorizing tank 5 is installed in the upper part of the generating furnace 3, and this deodorizing tank 5 is equipped with an exhaust blower 6 and a circulation pump 7. ``-□゛Paka(]tRIJQlt6ゎゎゎ゛゛゛□.ヮヮヮ゛゛゛゛゛゛゛゛゛゛□゛゛゛゛゛゛□゛゛□ .

。A chamber 8 is provided, and an outlet 3a of a hot air generating furnace 9.53 is opened on one side of the heat insulating wall 8a. Inside the hot air retention chamber 8, there are a head portion 8a consisting of a large diameter portion, and a neck portion 9b consisting of a small diameter portion having a diameter of about 3 minutes of the large diameter portion.
When a funnel-shaped hot-blast stove 9 is provided in which the tubes are connected coaxially and in the five-way direction, a discharge port 10b is opened at the end of the neck portion 8b for both the tubes. A charging chamber 11 is provided in the upper part of the hot air storage chamber 8 so as to cover the opening upper part 10a of the hot air stove 9, and a charging chamber 11 is attached to the charging chamber 11. Hot stove 9a head 8a
A plurality of hot air introduction pipes 13 are arranged in the upper and lower circumferential directions in the neck part 9b.
．． 13.13...0 is attached downward, and
Its ejection side is flush with the inner wall of the hot air stove 9. A discharge chamber 14 is provided around the discharge port tab of the hot air stove 9,
A container 15 is placed in the discharge chamber 14 facing the discharge port 1Ob, and discharged to the - side! 1B is installed. And an exhaust pipe 17 with one end connected to the deodorizing tank 5
The other end is connected to the discharge chamber 14 and the input chamber 11, respectively.

させてやり投入蓋１２を閉じる。Now, after igniting the burner 2 and turning on the blower 1, and confirming that the temperature inside the hot air stove 9 has reached approximately 200°C, open the charging lid 12 and remove various miscellaneous materials such as malt blend, styrofoam, polyethylene, etc. The waste plastic mixture is introduced and the spear introduction lid 12 is closed.

遊保持される。Then, at this time, the hot air has already passed through the hot air storage chamber 8 from the hot air generating furnace 3, and is transferred to the hot air furnace 9 from the hot air introduction pipes 13, 13, 13, and so on.
The hot air being sent inside swirls and flows downward along the inner wall of the hot air stove 9, from the neck 9b toward the outlet 1'Ob side, and then reverses and becomes an even stronger upward airflow that flows through the hot air stove 9. Since the plastic is blown upward, the first piece of waste plastic that has not yet been softened and melted is introduced from the input chamber 11 by this wind force and is kept floating without falling directly toward the discharge port 10b.

とになる。When the amount of waste plastic input increases, the waste plastic condenses at the neck, which has a small diameter.
While this pressure prevents each other from falling toward the discharge port side, the hot air introduction pipe 13. +3.
13... The hot air introduced from the hot air stove 9 swirls
Since a gap 18 is created between the inner wall of the tube and the outer periphery of the thrown-in lump of waste plastic, the thrown-in lump of waste plastic 18 can absorb the introduced hot air as shown in Fig. 2. Due to the rising air current and the rotating air current, the air is heated while being rotated in a suspended state within the hot air stove 9.
そして、この加熱は一方においては熱風滞溜室８内の熱
風による熱風炉９を介しての間接加熱と、熱風導入管１

熱風による直接加熱による三段加熱である。This heating is achieved on the one hand by indirect heating using hot air in the hot air storage chamber 8 via the hot air furnace 9, and on the other hand, by indirect heating via the hot air furnace 9 using the hot air in the hot air retention chamber 8, and by indirect heating through the hot air inlet pipe 1.
This is three-stage heating by direct heating by hot air introduced into the hot blast furnace 9 via 3.13.13...
ところで、都市ゴミや産業廃棄物の中には、前述のよう

れる。By the way, as mentioned above, an extremely wide variety of plastics are mixed in municipal garbage and industrial waste, and the mixing ratio of these and other wastes also varies. Therefore, the heating temperature in the hot air stove 9 can be selected from about 150°C to about 400°C, but generally, if the temperature exceeds 400°C, the plastic will begin to burn and the amount of gas generated will increase, so it is not preferable. Because there is no temperature, the temperature can be kept below 400℃.

中心部下方へ移動させる。However, if the heating temperature exceeds 300°C, dioxin may be generated depending on the type of plastic, so the most preferable heating temperature is in the range of 150°C to 200°C. Within this temperature range, the waste plastic softens without melting, and as the specific gravity increases, it resists the upward airflow and reaches the outlet port.
It falls to the Ob side. The reason why indirect heating and direct heating are used together to heat the hot air stove 9 is that the former provides sufficient heat to the entire hot air stove 9, and the latter uses direct heating to adjust the heating state inside the hot air stove 9. Hot air introduction pipes 13.1 are attached to the peripheral wall of the hot air stove 9 in the circumferential direction upward and downward and downward.
3. The hot air blown downward in a spiral shape from No. 13-. softens, melts, and condenses the inserts of the hot air stove 9 while preventing the plastic from depositing on the inner wall of the hot air stove 9, so that the hot air blows downward from the center of the hot air stove 9. Move to.

5, leading to a fall.
その際、軟化しない熱硬化性樹脂や、石、生ゴミ等は、

へスムースに引っかかることなく落下する。At that time, thermosetting resins that do not soften, stones, garbage, etc.
Since there is no obstruction such as a holding rod at the discharge port unlike in the conventional case, the plastic material falls smoothly into the container 15 together with the softened and molten plastic without getting caught.

せられる。On the other hand, wood, paper, etc. are burned, and ash and other solid materials fall to the discharge port 10b together with softened and molten plastic, but some of the combustion gases, together with other generated gases, reach the input chamber 11 and are discharged from the upper part of the inlet chamber 11. The other part is led to the deodorizing tank 5 through the exhaust pipe 17 connected to the exhaust chamber 14 from the discharge port lαb, and the other part is also led to the deodorizing tank 5 through the exhaust pipe 17 connected to the discharge chamber 14 from the discharge port lαb, and after being deodorized, the exhaust blower 6, it is released to the outside.
容器１５に軟化溶融した廃プラスチックが溜まったとこ
ろで、排出Ｍ１Ｂを開いてこれを外部へ取り出し、固化
整形させるものである。When the softened and molten waste plastic has accumulated in the container 15, the discharge M1B is opened to take it out to the outside, where it is solidified and shaped.

The volume can be reduced to 1/0, and it is extremely easy to handle whether it is recycled (secondary treatment) or landfilled.
