処迷ｆｉ
一般に、各種形状の被塗装物を塗装する際、被塗装物を
ハンガーに吊してペインテングプース内で塗装するが、
同一ハンがーを何回も繰返して使用すると、ハンガ一自
体にも塗料が固着する。Generally, when painting objects of various shapes, the object is hung on a hanger and painted inside a painting booth.
If you use the same hanger over and over again, paint will stick to the hanger itself.
特に、静電塗装においては、ハンガーに塗料が固着して
いると導電性が悪《なって塗着率が低下するばかりでな
く、被塗装物も掛けられなくなる。Particularly in electrostatic painting, if the paint is stuck to the hanger, the conductivity will deteriorate and not only will the coating rate decrease, but the object to be painted will not be hung.
そのため、ハンガーは何回か使用すると、固着している
塗料を酸性液等の塗料剥離剤に約１週間程浸して剥離さ
せるか、又は、焼却炉か屋外で固着塗料を焼却した後、
その燃焼生成物を人手によってハンマー等で叩き落とす
方法が採られている。Therefore, after using the hanger several times, the stuck paint must be removed by soaking it in a paint remover such as an acid solution for about a week, or the stuck paint must be incinerated in an incinerator or outdoors.
A method is adopted in which the combustion products are manually knocked off with a hammer or the like.

上記従来方法の内、塗料剥離剤を用いる場合には、使用
する液が酸性であるため、作業中に酸液が飛散して作業
者の被服や皮膚を傷めるばかりでなく、固着塗料の剥離
処理に要する日数が掛がり過ぎること、及び使用済みの
廃液処理に困る等の問題点があった。Among the conventional methods mentioned above, when using a paint remover, the liquid used is acidic, so the acid liquid scatters during work and can damage the clothes and skin of the worker. However, there were other problems such as it took too many days to remove the fixed paint and it was difficult to dispose of the used waste liquid.
一方、塗料が固着したハンガーを焼却炉や屋外にて焼却
処理する場合には、ハンガー材料の多くが軟鋼であるた
め燃焼温度を十分に管理していないと熱歪みが発生する
恐れがあり、また、多量の黒煙が発生して大気汚染の原
因にもなる等の問題点があった。On the other hand, when incinerating hangers with adhered paint in an incinerator or outdoors, there is a risk of thermal distortion if the combustion temperature is not adequately controlled, as most of the hanger materials are made of mild steel. However, there were problems such as a large amount of black smoke being generated and causing air pollution.
さらに、ハンガーに固着した燃焼生成物は、人手により
ハンマー等にて叩き落とす必要があり、その叩き落とし
作業が重労働であるばかりでなく経済的でない等の問題
点があった。Furthermore, the combustion products that adhere to the hanger must be manually knocked off using a hammer or the like, which poses problems such as not only is the work of knocking it off hard labor but also uneconomical.

を特徴とする。[Structure of the Invention] The method for recycling paint hangers of the present invention for answering Question 3LL17 is to install a conveyor in which a plurality of hanging fittings are appropriately arranged in a loop, and to hang the hangers to which paint has adhered. After hanging the hanger on a metal fitting and incinerating the stuck paint on the hanger in an incinerator, an external impact is applied to the hanger in the vacuum chamber to remove the combustion products stuck on the hanger. The method is characterized by cleaning the surface of the hanger with a cleaning solution in a spray chamber, and then increasing the temperature inside the incinerator to 400°C to 400°C.
It is characterized by maintaining the temperature in the range of 50°C, and reburning the exhaust gas from the incinerator in the temperature range of 700°C to 750°C in a reburning furnace.

。Furthermore, the liquid supplied to the spray chamber is characterized in that it is a used liquid from which the solid content has been removed in a filter or a sedimentation tank. I will explain.
図において、本発明方法を実施する装置は主に、ループ
状に装設されたコンベヤー１と、焼却炉４と、再燃炉７
と、シミツカ−室１０と、スプレー室１３から成る。In the figure, the apparatus for carrying out the method of the present invention mainly includes a conveyor 1 installed in a loop, an incinerator 4, and a reburning furnace 7.
It consists of a smudger chamber 10 and a spray chamber 13.

内を移動しながら徐々に加熱され焼却炉４内に移送され
る。First, the conveyor 1 is moved at a speed determined by the shape and thickness of the hanger and the state of adhesion of the paint. When a hanger 3 with paint adhered to it is suspended from a hanging fitting 2 attached to the conveyor 1, the hanger 3 is gradually heated while moving within the booth and is transferred to an incinerator 4.

保持する。When transferred into the incineration path 4, the paint adhering to the hanger 7y-3 is burned and becomes a combustion product. This heating temperature is
The temperature is maintained at a temperature that has little thermal influence on the mild steel that is the base material of the hanger 3 and is sufficient to start igniting the paint, for example, about 400°C.
焼却炉４の温度保持は、ハンガーに固着している塗料の
燃焼による発熱分と、焼却炉４に取付けられている複数
台の燃焼用バーナー５のオン・オフ調整および冷却７７
ン２３の風量調整により行なわれる。The temperature of the incinerator 4 is maintained by the heat generated by the combustion of the paint stuck to the hanger, the on/off adjustment of the multiple combustion burners 5 attached to the incinerator 4, and the cooling 77.
This is done by adjusting the air volume of the fan 23.

Exhaust gas is sent by a suction 7 to a reheating furnace 7 which is pre-maintained at 700 to 750 degrees Celsius by a reheating furnace 7, where unburned gas is combusted, and organic harmful substances are decomposed into harmless substances. released into the atmosphere.

して灰ボックス１２に排出、堆積させる。The hanger 7y-3 suspended on the conveyor 1 leaves the incinerator 4 and is transferred to the next stain car room 1o. In the shocker chamber 10, a punch-type shocker 10a provided at the top of the chamber continuously applies a vibration shock to the hanger 7y-3 to which the combustion products are fixed, thereby removing combustion products from the base material surface of the handler ff-3. Objects are knocked down, discharged and deposited in an ash box 12 via a popper 11.

By spraying water onto the surface of the hanger 7y-3 using the nozzle 14, remaining combustion products are washed away and the hanger 3 is cooled.
スプレー室１３を出たハング−はコンベヤー１に吊下げ

手により吊り金！４ｃ２から外される。The cooled and regenerated hang 22 is moved to the hanger outlet by the conveyor 1 while being dried on the way, and is manually removed from the hanger. Removed from 4c2.

タンク１５に戻される。The fine particles settled below the sedimentation tank 19 are further sent to the centrifugal H1 iso 20 and separated into water and sludge, the sludge is discharged to the sludge tank 21, and the water is returned to the spray tank 15. .
このため、スプレー室への供給液体は循環利用されるた
め補給水は極く僅かで済むことになる。Therefore, since the liquid supplied to the spray chamber is recycled, only a small amount of make-up water is required.

なう必要はなく、又、何等の経験も必要としない。[Effects of the Invention] The paint hanger recycling method of the present invention includes incineration of paint stuck to the hanger, removal of combustion products, cleaning and cooling, and
Since each process, such as drying, is carried out continuously and automatically, the operator can simply attach the paint-fixed hanger to the conveyor and remove it after recycling, without having to perform any dangerous work. No experience is required.
さらに、焼却炉で発生する排ガスも再燃炉において、再
燃焼されるため大気汚染等の心配もない。Furthermore, since the exhaust gas generated in the incinerator is reburned in the reburning furnace, there is no need to worry about air pollution.
