Description

発明の詳細な説明Detailed Description of the Invention

本発明は水分を多く含む被処理物を乾燥させる乾燥装置であり、この乾燥装置内部の温度を熱効率よく急速短時間で上昇させる手段であり、請求項1,2を組み合わせる事により、一段と昇温が加速できる。
即ち、
1)乾燥装置内部に設けたバッド底面の全面に平面ヒーターを直に貼りつける。
2)乾燥装置内部の全面とバッドの表面に熱放射性塗料を塗布して、1)伝導熱 2)対流熱、3)副射熱(遠赤外線放射)を同時に発生させる。
以上、1),2)の効果を組み合わせる事により、急速短時間に温度を上昇させ熱効率よく水分を除去し、被処理物を乾燥する事を特徴とした乾燥装置に関するものである。
The present invention is a drying apparatus that dries an object to be processed that contains a lot of moisture, and is a means for increasing the temperature inside the drying apparatus efficiently and rapidly in a short time. By combining claims 1 and 2, the temperature is further increased. Can accelerate.
That is,
1) A flat heater is directly attached to the entire bottom surface of the pad provided inside the drying apparatus.
2) A thermal radiation coating is applied to the entire surface of the drying apparatus and the surface of the pad to simultaneously generate 1) conduction heat, 2) convection heat, and 3) side heat (far infrared radiation).
As described above, the present invention relates to a drying apparatus characterized by combining the effects 1) and 2) to rapidly raise the temperature in a short time, remove moisture efficiently, and dry the workpiece.

従来、乾燥装置としては多種類の形態のものが知られているが、乾燥装置内の加熱方法は主として、装置の下部又は上部に棒状ヒーターを取りつけ、且つ外部から内部に空気を吹きこみ、乾燥装置内部を循環させて温度を上昇させる方式が採用されているのが一般的である。この方式では熱効率が悪く、乾燥に長時間費やし運転時間のロスや電気費用が高くつく事が欠点となっている。
このような現状から熱効率が良く、少ないエネルギーで短時間に目的の乾燥が達成される事が望まれていた。
Conventionally, various types of drying apparatuses are known, but the heating method in the drying apparatus is mainly performed by attaching a bar heater to the lower or upper part of the apparatus and blowing air from the outside to the inside. Generally, a method of circulating the inside of the apparatus to raise the temperature is adopted. This method is disadvantageous in that heat efficiency is poor, drying takes a long time, operating time is lost, and electric costs are high.
From such a current situation, it has been desired that the desired drying is achieved in a short time with a small amount of energy and good thermal efficiency.

乾燥装置内部の昇温システムにおいて、特許文献の如く、熱源(ヒーター)が乾燥装置の上部又は下部に設置され、又バッドにも直接ヒーターが組みこまれていない。このため乾燥装置内部の昇温が遅くなる原因となっていた。In the temperature raising system inside the drying apparatus, as in the patent document, a heat source (heater) is installed at the upper or lower part of the drying apparatus, and the heater is not directly incorporated into the pad. For this reason, it has become a cause of slowing the temperature rise inside the drying apparatus.

又、乾燥装置内部の材質は、一般に炭素鋼,ステンレス鋼,アルミニウム,亜鉛メッキ鋼及び弗素コート鋼等が、そのままの状態で内壁として使われている。
これらの材質のみでは副射熱の効果が期待できず、熱効率を充分に得るための試みがなされていない。
In general, carbon steel, stainless steel, aluminum, galvanized steel, fluorine-coated steel, etc. are used as the inner wall as the material inside the drying apparatus.
Only these materials cannot be expected to have the effect of secondary heat, and no attempt has been made to obtain sufficient thermal efficiency.

特許文献2,3に熱放射性塗料の利用が記載されている。しかし、この様な塗料は電子及び電気機器への応用が検討されているが、乾燥装置への熱効率を高める技術には一切触れていない。Patent Documents 2 and 3 describe the use of thermal radiation paints. However, such paints are being studied for application to electronic and electrical equipment, but do not mention any technology for improving the thermal efficiency of the drying apparatus.

近年、環境汚染の問題から石油、天然ガス等の利用を減らし電気への移行が急務となっている。しかし、2011年3月の東北地震による原発の事故により、電気の供給も困難な状態となっている。
本発明は、この様な事態を解決すべく優れた熱効率を有する乾燥装置を提供し、エネルギーの節約を追求するものである。
In recent years, there has been an urgent need to shift to electricity by reducing the use of oil, natural gas, etc. due to environmental pollution problems. However, due to the nuclear accident caused by the Tohoku Earthquake in March 2011, the supply of electricity has become difficult.
The present invention provides a drying apparatus having excellent thermal efficiency to solve such a situation, and seeks to save energy.

課題を解決するための手段Means for solving the problem

上記課題を解決するために、本発明は被処理物の水分を除去して乾燥する乾燥装置であって、乾燥装置内部のバッド底面の全面に平面ヒーターを貼りつけ、且つ乾燥装置内部の全面とバッドの表面に熱放射性塗料を塗布し、被処理物を急速短時間で熱効率よく乾燥させる事を特徴とする乾燥装置である。In order to solve the above problems, the present invention is a drying apparatus that removes moisture from an object to be processed and dries, and a flat heater is attached to the entire bottom surface of a pad inside the drying apparatus. It is a drying apparatus characterized in that a thermal radiation coating is applied to the surface of a pad, and the object to be processed is dried with high efficiency in a short time.

発明の効果Effect of the invention

本発明の乾燥装置は優れた熱効率が得られ、被処理物(水分を多く含む産業用廃液,及び食品残渣物等)を急速短時間で乾燥する事ができる乾燥装置である。The drying device of the present invention is a drying device that can obtain excellent thermal efficiency and can dry the object to be treated (such as industrial waste liquid containing a lot of water and food residue) in a short time.

乾燥装置の一例を示した正面図である(1皿タイプ)It is the front view which showed an example of the drying apparatus (one dish type) 乾燥装置の一例を示した側面図である(1皿タイプ)It is a side view showing an example of a drying device (one dish type)

従来の乾燥装置は熱源(ヒーター)を乾燥装置の上部又は下部に取りつけて加熱し、外部より空気を吹きこんで内部を循環させ、この対流熱のみを利用して温度を上げているために温度の上昇が遅くなり、水分を多く含んだ被処理物の乾燥に長時間要していた。In conventional drying equipment, a heat source (heater) is attached to the top or bottom of the drying equipment and heated, and air is blown from outside to circulate the inside. As a result, it took a long time to dry the object containing a lot of moisture.

本発明の乾燥装置は被処理物を貯めたバッドの底部の全面に半導体接点を組みこんだ平面ヒーターを貼りつけ、直に加熱する事により少ない電力で急速短時間に温度を上げ、電気エネルギーを最大限効率のよい方法で目的の温度に到達させ、乾燥を行う事ができる。In the drying apparatus of the present invention, a flat heater incorporating a semiconductor contact is attached to the entire bottom surface of the pad where the object to be processed is stored. The target temperature can be reached and dried by the most efficient method.

又、本発明の乾燥装置は装置内部の全面及びバッドの表面に熱放射性塗料を塗布する事により、内部の熱伝達は伝導熱,対流熱及び広範囲の波長をもつ副射熱の3要素が最大限の熱効率をもたらし、急速短時間で被処理物の乾燥を行う事ができる。In addition, the drying apparatus of the present invention applies heat radiation paint to the entire surface of the inside of the apparatus and the surface of the pad, so that the internal heat transfer is maximized by three elements of conduction heat, convection heat, and side heat with a wide range of wavelengths. It offers the ultimate thermal efficiency and can dry the workpiece in a short time.

本発明の乾燥装置は上記[0012][0013]で記述した如く、乾燥装置内部の底部の全面に平面ヒーターを貼りつけて昇温を速め、尚且つ乾燥装置内部の全面及びバッドの表面に熱放射性塗料を塗布し、伝導熱,対流熱及び副射熱を同時に発生させる事により最大限の熱効率を得る事が可能となった。
又、従来型の乾燥装置(例・[特許文献1]特開2005−61809号)にも本発明は利用する事ができる。
As described in the above [0012] and [0013], the drying apparatus of the present invention attaches a flat heater to the entire bottom surface of the drying apparatus to accelerate the temperature rise, and heats the entire surface of the drying apparatus and the surface of the pad. By applying radioactive paint and generating conduction heat, convection heat, and side heat, the maximum thermal efficiency can be obtained.
The present invention can also be used in conventional drying apparatuses (eg, [Patent Document 1] JP 2005-61809).

本発明の乾燥装置の[0012]の項で記述した如く、平面ヒーターの素材としてAl合金−金属半導体,Al−Mg−金属半導体及びAu−金属半導体が用いられる。As described in the section [0012] of the drying apparatus of the present invention, an Al alloy-metal semiconductor, an Al-Mg-metal semiconductor, and an Au-metal semiconductor are used as the material for the flat heater.

本発明の乾燥装置の[0013]の記述の如く、熱放射性塗料の着色剤の素材として、カーボンブラック,又はチタンブラックを混合した黒色塗料及びフタロシアニンブラック,又はアニリンブラックを混合した黒色塗料等の無機系着色剤や有機系着色剤が用いられる。
又、その他の素材としてSiO−Sb系の半導体と樹脂を混合した塗料,及び焼成セラミックス等が用いられる。
As described in [0013] of the drying apparatus of the present invention, as a colorant material of the thermal radiation paint, inorganic materials such as black paint mixed with carbon black or titanium black and black paint mixed with phthalocyanine black or aniline black System colorants and organic colorants are used.
As other materials, a paint in which a SiO 2 —Sb 2 O 5 based semiconductor and a resin are mixed, and fired ceramics are used.

上記樹脂の素材としては、弗素樹脂,シリコーン樹脂,フェノール樹脂,エポキシ樹脂,ポリエステル樹脂及びその他の耐熱性プラスチック樹脂が用いられる。As the material of the resin, fluorine resin, silicone resin, phenol resin, epoxy resin, polyester resin, and other heat resistant plastic resins are used.

上記熱放射性塗料は水性型,溶剤型,エマルジョン型及び粉体型のいずれの形態で塗布してもよい。塗布する場合の塗膜は10〜100μmが適当であるが、これより薄くなると大きなピンホールが生じ易く、副射熱の効果が損なわれる事がある。The thermal radiation paint may be applied in any form of a water-based type, a solvent type, an emulsion type and a powder type. The coating film for application is suitably 10 to 100 μm, but if it is thinner than this, a large pinhole is likely to occur, and the effect of secondary heat may be impaired.

本発明の乾燥に用いる被処理物は液状,ペースト状,スラリー状及び粘度状等の水分を含んだ産業用廃液や食品残渣物であり乾燥する事ができる。
産業用廃液としては例えば接着剤,インキ,及び塗料等であり、食品残渣物としては例えばおから,酒粕,米飯,及びうどん等を乾燥する事ができる。
The object to be treated used for drying of the present invention is an industrial waste liquid or food residue containing water such as liquid, paste, slurry and viscosity, and can be dried.
Industrial waste liquids include, for example, adhesives, inks, paints, and the like, and food residues such as okara, sake lees, cooked rice, and udon can be dried.

次に本発明に係わる乾燥装置の実施例を概略正面図,1及び側面図,2を用いて説明する。被処理物を投入するバッド1が設けており、このバッド1に被処理物を容器又は移送ポンプを用いて投入する。バッド1の内面に被処理物の密着を防止するために予め剥離紙を敷いておいても良い。剥離紙の素材はP・E(又はシリコン)−クラフト紙,及びAl−PET等の積層フィルムが用いられる。Next, an embodiment of a drying apparatus according to the present invention will be described with reference to a schematic front view, 1 and a side view. A pad 1 for supplying a workpiece is provided, and the workpiece is charged into the pad 1 using a container or a transfer pump. In order to prevent the object to be treated from sticking to the inner surface of the pad 1, release paper may be laid in advance. As the material of the release paper, P · E (or silicon) -kraft paper and laminated film such as Al-PET are used.

A flat heater 2 is attached to the entire bottom surface of the pad.
The pad 1 and the flat heater 2 are in close contact with each other. A soft support plate 3 is fixed to the lower part. The support plate 3 retains the adhesiveness between the pad 1 and the flat heater 2 and also prevents the flat heater 2 from falling.

乾燥装置の上部に開閉可能な乾燥バッド蓋,4が設けられている。
このバッド蓋,4を密閉する事により初期に伝導熱,対流熱を発生させる。
本発明において、乾燥装置内部の全面と乾燥バッド蓋,4及びバッド,1の表面は熱放射性塗料が塗布されており、温度が上昇するに従って副射熱を増大させ、一段と熱効率を高める事ができる。
A drying pad lid 4 that can be opened and closed is provided at the top of the drying device.
By initially sealing the pad lid 4, conduction heat and convection heat are generated.
In the present invention, the entire surface inside the drying apparatus and the surfaces of the drying pad lid 4 and the pads 1 and 1 are coated with a heat-radiating paint. As the temperature rises, the secondary heat is increased and the thermal efficiency can be further improved. .

被処理物を乾燥させる工程で、多くの水蒸気が発生する。
この発生した水蒸気は排気ブロワー,5で排気筒,6に送り外部へ放出される。
又、同時に一部の水蒸気は熱源として乾燥装置内部でリサイクルし、熱エネルギーの有効利用することも出来る。
A lot of water vapor is generated in the process of drying the workpiece.
The generated water vapor is sent to the exhaust tube 6 by the exhaust blower 5 and discharged to the outside.
At the same time, a part of the water vapor can be recycled inside the drying apparatus as a heat source to effectively use the heat energy.

尚、本発明の乾燥装置において、図1,2に示したバッドは一皿であるが、被処理物の量が増えるに従って複数皿にしてもよい。
複数皿にする事により平面ヒーターの数も比例式に増え、上述したように伝導熱,対流熱及び副射熱の作用により熱効率が一段と増すことになる。
In the drying apparatus of the present invention, the pad shown in FIGS. 1 and 2 is one dish, but a plurality of dishes may be used as the amount of the object to be processed increases.
By using a plurality of dishes, the number of flat heaters also increases proportionally, and as described above, the thermal efficiency is further increased by the action of conduction heat, convection heat, and side heat.

以上のように本発明によれば被処理物、例えば接着剤,インキ,塗料等の産業用廃液及びおから,酒粕,米飯等の食品残渣物を乾燥装置内部のバッドに貯めて乾燥させる時、バッドの底面の全面に平面ヒーターを貼りつけて、急速短時間に目的の温度に到達させると共に、最大限の熱効率を上げるために乾燥装置内部の全面及びバッドの表面に熱放射性塗料を塗布し、乾燥装置内部において伝導熱,対流熱及び副射熱(遠赤外線放射)の3要素を同時に発生させ、急速短時間で被処理物を乾燥する事ができた。
これによって乾燥装置の小型化,設置面積の縮小化,乾燥装置の易移動性及び運転時間の短縮化等、安価な運転経費で乾燥する事が可能となった。
As described above, according to the present invention, when processing waste, such as industrial waste liquids such as adhesives, inks and paints, and okara, food residues such as sake lees and cooked rice are stored in a pad inside the drying apparatus and dried. A flat heater is attached to the entire bottom surface of the pad to reach the target temperature in a short time, and in order to maximize the thermal efficiency, a thermal radiation paint is applied to the entire surface of the drying device and the surface of the pad. Three elements of conduction heat, convection heat, and side heat (far-infrared radiation) were generated at the same time in the drying device, and the workpiece could be dried in a rapid and short time.
This makes it possible to dry at low operating costs, such as downsizing the drying device, reducing the installation area, easy mobility of the drying device, and shortening the operation time.

次に本発明に係わる乾燥装置の実施例を概略正面図,1及び側面図,2を用いて説明する。被処理物を投入するバッド1が設けており、このバッド1に被処理物を容器又は移送ポンプを用いて投入する。バッド1の内面に被処理物の密着を防止するために予め剥離紙を敷いておいても良い。剥離紙の素材はP・E(又はシリコン)−クラフト紙,及びAl−PET等の積層フィルムが用いられる。Next, an embodiment of a drying apparatus according to the present invention will be described with reference to a schematic front view, 1 and a side view. A pad 1 for supplying a workpiece is provided, and the workpiece is charged into the pad 1 using a container or a transfer pump. In order to prevent the object to be treated from sticking to the inner surface of the pad 1, release paper may be laid in advance. As the material of the release paper, P · E (or silicon) -kraft paper and laminated film such as Al-PET are used.

バッドの底面の全面に平面ヒーター2が貼りつけられている。
このバッド,1と平面ヒーター,2は密着している。その下部には軟質の支え板,3が固定されている。この支え板,3はバッド,1と平面ヒーター,2の密着性を保持し、又平面ヒーター,2の落下防止も兼備えている。
A flat heater 2 is attached to the entire bottom surface of the pad.
The pad 1 and the flat heater 2 are in close contact with each other. A soft support plate 3 is fixed to the lower part. The support plate 3 retains the adhesiveness between the pad 1 and the flat heater 2 and also prevents the flat heater 2 from falling.

乾燥装置の上部に開閉可能な乾燥バッド蓋,4が設けられている。
このバッド蓋,4を密閉する事により初期に伝導熱,対流熱を発生させる。
本発明において、乾燥装置内部の全面と乾燥バッド蓋,4及びバッド,1の表面は熱放射性塗料が塗布されており、温度が上昇するに従って副射熱を増大させ、一段と熱効率を高める事ができる。
A drying pad lid 4 that can be opened and closed is provided at the top of the drying device.
By initially sealing the pad lid 4, conduction heat and convection heat are generated.
In the present invention, the entire surface inside the drying apparatus and the surfaces of the drying pad lid 4 and the pads 1 and 1 are coated with a heat-radiating paint. As the temperature rises, the secondary heat is increased and the thermal efficiency can be further improved. .

被処理物を乾燥させる工程で、多くの水蒸気が発生する。
この発生した水蒸気は排気ブロワー,5で排気筒,6に送り外部へ放出される。
又、同時に一部の水蒸気は熱源として乾燥装置内部でリサイクルし、熱エネルギーの有効利用する事もできる。
A lot of water vapor is generated in the process of drying the workpiece.
The generated water vapor is sent to the exhaust tube 6 by the exhaust blower 5 and discharged to the outside.
At the same time, a part of the water vapor can be recycled inside the drying apparatus as a heat source to effectively use the heat energy.

尚、本発明の乾燥装置において、図1,2に示したバッドは一皿であるが、被処理物の量が増えるに従って複数皿にしてもよい。
複数皿にする事により平面ヒーターの数も比例式に増え、上述したように伝導熱,対流熱及び副射熱の作用により熱効率が一段と増すことになる。
In the drying apparatus of the present invention, the pad shown in FIGS. 1 and 2 is one dish, but a plurality of dishes may be used as the amount of the object to be processed increases.
By using a plurality of dishes, the number of flat heaters also increases proportionally, and as described above, the thermal efficiency is further increased by the action of conduction heat, convection heat, and side heat.

発明の効果Effect of the invention

以上のように本発明によれば被処理物、例えば接着剤,インキ,塗料等の産業用廃液及びおから,酒粕,米飯等の食品残渣物を乾燥装置内部のバッドに貯めて乾燥させる時、バッドの底面の全面に平面ヒーターを貼りつけて、急速短時間に目的の温度に到達させると共に、最大限の熱効率を上げるために乾燥装置内部の全面及びバッドの表面に熱放射性塗料を塗布し、乾燥装置内部において伝導熱,対流熱及び副射熱(遠赤外線放射)の3要素を同時に発生させ、急速短時間で被処理物を乾燥する事ができた。
これによって乾燥装置の小型化,設置面積の縮小化,乾燥装置の易移動性及び運転時間の短縮化等、安価な運転経費で乾燥する事が可能となった。
As described above, according to the present invention, when processing waste, such as industrial waste liquids such as adhesives, inks and paints, and okara, food residues such as sake lees and cooked rice are stored in a pad inside the drying apparatus and dried. A flat heater is attached to the entire bottom surface of the pad to reach the target temperature in a short time, and in order to maximize the thermal efficiency, a thermal radiation paint is applied to the entire surface of the drying device and the surface of the pad. Three elements of conduction heat, convection heat, and side heat (far-infrared radiation) were generated at the same time in the drying device, and the workpiece could be dried in a rapid and short time.
This makes it possible to dry at low operating costs, such as downsizing the drying device, reducing the installation area, easy mobility of the drying device, and shortening the operation time.
