【考案の詳細な説明】
この考案は印刷等の塗装を施した金属板の焼付は乾燥を
行う乾燥機の改良に関するものである。[Detailed Description of the Invention] This invention relates to an improvement of a dryer for baking and drying a metal plate that has been coated with printing or other coatings.
プリントした鋼板は乾燥機の入口において機内を走行す
るコンベヤの受枠に一枚一枚のせられて長手の乾燥機の
室内を通り抜ける。At the entrance of the dryer, the printed steel plates are placed one by one on a receiving frame of a conveyor running inside the machine and passed through the long dryer chamber.
その間に室内を循環する熱風が鋼板9焼付は乾燥を行う
。During this time, the hot air circulating in the room dries the steel plate 9.
乾燥機に入るとプリントした塗料中の溶媒が煙霧化し、
この煙霧が乾燥機室内の天井において凝結し、その凝結
したものが下を通る鋼板の上に滴下して鋼板の品質を損
うという問題がこれまでしばしば起きていた。When the paint goes into the dryer, the solvent in the printed paint becomes atomized.
This fume condenses on the ceiling of the dryer room, and the condensed material drips onto the steel plates passing below, often causing problems in the quality of the steel plates.
この考案の目的は乾燥機の天井における煙霧の凝結を防
止して上記問題を解決することにある。The purpose of this invention is to solve the above problem by preventing the condensation of fumes on the ceiling of the dryer.
その要旨とするところは乾燥機の煙霧が凝結しやすい区
間の両側面に内外二重壁を設け、内壁と外壁の間に形成
した側面ダクトに出口に近い機内の空気を壜入れて加熱
した熱風を導き、天井付近に多数の左右の側面ダクトを
内通する中空管を配設し、それらにより天井を高温に保
持して煙霧の凝結滴下を防止したことにある。The gist of this is that double walls are installed on both sides of the section where the smoke from the dryer tends to condense, and air from inside the machine near the outlet is heated in a bottle through a side duct formed between the inner and outer walls. A number of hollow tubes were placed near the ceiling that passed through the left and right side ducts, and these pipes kept the ceiling at a high temperature to prevent the condensation and dripping of smoke.
この考案の乾燥機を図面に示す実施例に基づいて説明す
る。The dryer of this invention will be explained based on an embodiment shown in the drawings.
第1図に示すように、原板1は乾燥機の入口において一
枚一枚コンベヤ3の受枠2にのせられる。As shown in FIG. 1, original sheets 1 are placed one by one on a receiving frame 2 of a conveyor 3 at the entrance of the dryer.
コンベヤ3の上段は原板1をのせて長手の乾燥機室内を
入口から出口へ進み、下段は空で出口から入口へ戻る。The upper stage of the conveyor 3 carries the original plate 1 and moves from the entrance to the exit in the long dryer chamber, and the lower stage is empty and returns from the exit to the entrance.
乾燥機の上屋4に左右−組の熱風循環用送風機6を設け
、両者の吸入側に共通の加熱器8を連結し、その加熱機
8に乾燥機室の天井に開口する取り入れダクト7を連結
する。A left and right pair of hot air circulation blowers 6 are installed in the dryer shed 4, a common heater 8 is connected to the suction side of both, and an intake duct 7 is connected to the heater 8 to open into the ceiling of the dryer room. Link.
入口から堆り入れダク)7までの乾燥機の区間は原板1
の加熱域であり、煙霧の発生する区間である。The section of the dryer from the entrance to the composting duct) 7 is the original board 1.
This is the heating area and the area where smoke is generated.
この加熱域のコンベヤ3の上段をはさむ部分の両側壁を
内外二重に構成して側面ダクト9を設ける。A side duct 9 is provided by making both side walls of the portion sandwiching the upper stage of the conveyor 3 in this heating area double-walled inside and outside.
第2図に示すように、左右の送風機6,6′の吐出口は
左右の側面ダクト9,9′の上部に開口する。As shown in FIG. 2, the discharge ports of the left and right blowers 6, 6' open at the tops of the left and right side ducts 9, 9'.
側面ダクト9,9′は全長にわたり乾燥機のコンベヤ3
の上段と中段の間に開口する。The side ducts 9, 9' are connected to the dryer conveyor 3 over the entire length.
It opens between the top and middle tiers.
天井付近において、左右の側面ダクl−9,9’を内通
する中空管5を設ける。Near the ceiling, a hollow tube 5 is provided that passes through the left and right side ducts 1-9 and 9'.
中空管5は第1図に示すようにダクトの全長にわたり多
数−列に配設する。The hollow tubes 5 are arranged in multiple rows over the entire length of the duct as shown in FIG.
次に、この考案の乾燥機によるプリント鋼板のMについ
て説明する。Next, M of the printed steel plate produced by the dryer of this invention will be explained.
プリント直後の原板1を乾燥機の入口でコンベヤ3の受
枠2にのせるとコンベヤ3は原板1を乾燥機内に搬入す
る。When the original plate 1 immediately after printing is placed on the receiving frame 2 of the conveyor 3 at the entrance of the dryer, the conveyor 3 carries the original plate 1 into the dryer.
加熱域の両側の側面ダクト9,9′からコンベヤ3の上
段と下段の間に熱風が吹き込み、原板1を急速に加熱ス
る。Hot air is blown between the upper and lower stages of the conveyor 3 from the side ducts 9, 9' on both sides of the heating area, and the original plate 1 is rapidly heated.
加熱に伴い原板上のプリント塗料の溶媒等が蒸発して煙
霧となり上昇する。As it heats up, the solvent of the print paint on the original plate evaporates, forming smoke and rising.
150℃ないし200℃の熱風が乾燥機の上部に配列し
た中空管5の内部を通り乾燥機の天井付近を高温に保持
しているため、煙霧は天井付近に付着して凝結すること
なく室内の空気と共に循環空気の壜入れダクト7に一部
は入り、残りは排気ファンを経て機外に放出される。Hot air at a temperature of 150°C to 200°C passes through the hollow tubes 5 arranged at the top of the dryer and maintains the area near the ceiling of the dryer at a high temperature, so the smoke does not adhere to the ceiling and condense inside the room. A part of the circulating air enters the bottle duct 7 along with the air, and the rest is discharged outside the machine via an exhaust fan.
煙霧が天井又はその付近に凝結しないので、凝結したも
のが原板1上に滴下して品質を損うおそれはない。Since the smoke does not condense on the ceiling or its vicinity, there is no risk that the condensed material will drip onto the original plate 1 and impair its quality.
上記の通り、煙霧の発生する加熱域の空気を循環させる
従来のものとは異なり、本考案の乾燥機は煙霧の少ない
加熱域と出口の間の空気な壜入れて循環させるから、煙
霧が加熱域に蓄積するおそれはなく、循環空気取入口か
らダクトに入った煙霧はダクト内で凝結し、鋼板を汚染
きせることばないという従来のものにはない優れた効果
を奏する
中空管5として、通常、円管な使用するが、放熱効果を
上げるため、表面積の大きい断面四角形又は六角形の角
型管、ひれ付き管等を使用することも可能である。As mentioned above, unlike conventional dryers that circulate air in the heating area where smoke is generated, the dryer of the present invention circulates air in a bottle between the heating area and the outlet where there is little smoke, so the smoke is heated. As a hollow pipe 5, there is no risk of accumulation in the area, and the smoke that enters the duct from the circulating air intake condenses inside the duct and does not contaminate the steel plate. Although a circular tube is used, it is also possible to use a rectangular tube with a large surface area, such as a rectangular or hexagonal cross-sectional tube, a tube with fins, etc., in order to improve the heat dissipation effect.
実施例の乾燥機は入口から始めの熱風循環を行う加熱域
に中空管を配列したが、必要があれば、次の調質域にも
側面ダクトと中空管を設けて天井付近の加熱を行うこと
はいうまでもない。In the dryer of the example, hollow tubes were arranged in the heating zone where hot air was circulated starting from the inlet, but if necessary, side ducts and hollow tubes were also installed in the next tempering zone to heat the area near the ceiling. Needless to say, it is necessary to do this.
