Description

本発明は，フィルタプレス装置用加温板に関し，さらに詳細には，乾燥機能付きフィルタプレス装置において，例えば有機汚泥などの脱水された有機性ケーキを乾燥する際に加熱媒体（例えば温水，水蒸気など）によりケーキを加温するフィルタプレス装置用加温板に関する。   The present invention relates to a heating plate for a filter press device, and more specifically, in a filter press device with a drying function, for example, when a dehydrated organic cake such as organic sludge is dried, a heating medium (for example, hot water, steam, etc.) This relates to a heating plate for a filter press device that heats the cake by the above method.

現在においては，従来は別途の工程であった乾燥工程を一つの装置に集約された乾燥機能付きフィルタプレス装置が開発されている。上記乾燥機能付きフィルタプレス装置として，例えば，隣接する濾板の間に一対のダイヤフラムと濾布を設け，濾布内に収容されたスラリーを圧搾して加圧脱水する圧搾機構が利用されるロールフィット（登録商標）プロセスと呼ばれる装置がある。かかるロールフィットプロセス装置は，濾過・圧搾により加圧脱水されて固形分の塊となったケーキを真空ポンプで吸引して水分の蒸発温度を下げた上で，上記圧搾膜（ダイヤフラム）に対して作動液に代えて温水を通過させることにより，圧搾膜を介してケーキを加熱して効果的に乾燥することができるフィルタプレス装置である。   At present, a filter press apparatus with a drying function has been developed in which a drying process, which has been a separate process in the past, is integrated into one apparatus. As the above-mentioned filter press device with a drying function, for example, a roll fit in which a pair of diaphragms and filter cloths are provided between adjacent filter plates, and a squeezing mechanism that compresses and dehydrates the slurry accommodated in the filter cloths ( There is an apparatus called a registered trademark process. Such a roll fit process device uses a vacuum pump to suck a cake that has been dehydrated by filtration and squeezing into a solid lump and lowers the evaporation temperature of the water, and then against the squeezed membrane (diaphragm). It is a filter press device that can effectively dry by heating the cake through the squeezing membrane by passing hot water instead of the working fluid.

しかしながら，上記圧搾膜は，ゴムや樹脂などの熱伝導性の悪い材料からなるため，特に有機性ケーキ（例えば，下水などの有機性汚泥）を効果的に加温することができずに，長時間の乾燥時間が必要であった。   However, since the above-mentioned squeezed membrane is made of a material having poor thermal conductivity such as rubber or resin, it is particularly difficult to effectively heat an organic cake (for example, organic sludge such as sewage). Time drying time was required.

近年においては，上記圧搾膜を介してケーキを加熱する方法に加えて，濾板と濾板との間に高い熱伝導性の金属板（加温板）を設置して，当該加温板に温水を供給することでケーキを効果的に加温する方法が試みられている。かかる方法により，特に有機性汚泥などの有機性ケーキの乾燥時間を短縮することが期待されている。 In recent years, in addition to the method of heating the cake through the compressed membrane, a highly thermally conductive metal plate (heating plate) is installed between the filter plate and the heating plate. Attempts have been made to effectively warm the cake by supplying warm water. This method is expected to shorten the drying time of organic cakes such as organic sludge.

例えば，図６に示すように，加温板８００は，金属製の一体構造からなり，金属製の加温板８００の厚さ方向には，スラリーを供給する原液供給口８４０，濾液排出口８５０が形成されている。また，加温板８００の左側部下方には，温水入口８１０が形成されており，例えば９０℃程度の温水が加温板に流入される。さらに，温水は，加温板８００の内部に形成された温水流通路８２０を通過して，加温板８００の上方に形成された温水出口８３０から外部に排出される。かかる温水の流通路８２０は，加温板両面の濾室に対応する箇所に熱が行き渡るように加温板全体に形成されており，温水が温水流通路８２０を通過することにより，加温板８００の熱がケーキに伝熱されて加温される。 For example, as shown in FIG. 6, the heating plate 800 has a metal integrated structure, and in the thickness direction of the metal heating plate 800, a stock solution supply port 840 for supplying slurry and a filtrate discharge port 850 are provided. Is formed. Further, a warm water inlet 810 is formed below the left side of the warming plate 800, and for example, warm water of about 90 ° C. flows into the warming plate. Further, the warm water passes through a warm water flow passage 820 formed inside the warming plate 800 and is discharged to the outside from a warm water outlet 830 formed above the warming plate 800. The warm water flow passage 820 is formed on the entire warming plate so that heat is distributed to locations corresponding to the filter chambers on both sides of the warming plate, and the warm water passes through the warm water flow passage 820 so that the warming plate is heated. 800 heat is transferred to the cake and heated.

しかしながら，上記加温板８００は，金属一体構造を有するため，加温板両面の濾室に対応する箇所に熱が行き渡るように温水の通路孔８２０を加工することが大変手間のかかる作業となっている。即ち，金属板８００ａに温水流通路８２０を形成するためには，金属板８００ａの側部から穴を貫通させた後，金属板８００ａの側面に隣接する穴を交互に連通させるように溝を形成して，金属製の角棒材８００ｂで側面を封じる必要がある。かかる金属製の角棒材８００ｂはネジ８００ｃにより金属板８００ａに固定されて，さらに，支持棒８００ｄが取り付けられる。 However, since the heating plate 800 has a metal integrated structure, it is very laborious to process the hot water passage hole 820 so that heat is distributed to locations corresponding to the filter chambers on both sides of the heating plate. ing. In other words, in order to form the hot water flow passage 820 in the metal plate 800a, grooves are formed so that holes adjacent to the side surfaces of the metal plate 800a are alternately communicated after passing through the holes from the side of the metal plate 800a. Therefore, it is necessary to seal the side surface with a metal square bar member 800b. Such a metal square bar member 800b is fixed to the metal plate 800a by a screw 800c, and a support bar 800d is further attached.

このように，金属一体型の加温板８００では，特に温水流通路８２０を形成するために，金属板８００ａの一側方から他側方への穴あけ作業が繁雑であるため，金属一体型の加温板を製造するために多くの作業時間が必要である，という問題がある。 As described above, in the metal-integrated warming plate 800, the drilling operation from one side of the metal plate 800a to the other side is complicated in order to form the hot water flow passage 820 in particular. There is a problem that a lot of work time is required to manufacture the heating plate.

さらに，かかる金属板８００ａは，通常，アルミニウムなどの金属の使用量が多いため，金属一体型の加温板では高価すぎることから実用化するのが困難である，という問題もある。 Furthermore, since the metal plate 800a normally uses a large amount of metal such as aluminum, there is a problem that it is difficult to put it into practical use because a metal-integrated heating plate is too expensive.

したがって，本発明の目的は，乾燥機能を付加したフィルタプレス装置で使用される加温板の温水流通路を簡易かつ容易に形成することができ，かつ加温板を安価で提供することが可能な新規かつ改良されたフィルタプレス装置用の加温板を提供することにある。   Therefore, an object of the present invention is to be able to easily and easily form a warm water flow passage for a heating plate used in a filter press apparatus having a drying function, and to provide a heating plate at a low cost. It is an object of the present invention to provide a heating plate for a new and improved filter press apparatus.

上記課題を解決するため，本発明の第１の観点においては，濾板と加温板とが交互に配置され，対向する濾板と加温板との間に濾布を介して濾室が形成されると共に，前記濾室内で脱水処理されたケーキを前記加温板で加温しながら乾燥処理することが可能な乾燥機能付きフィルタプレス装置において使用される前記加温板であって，前記加温板は，加温媒体の流通路を三層構造とし，欠損した樹脂板の両面に，所定厚さの金属板が張り合わされて形成されたものであると共に，前記樹脂板の欠損部分と前記金属板とにより形成された加温媒体流通路内を前記加温媒体が通過することにより，前記金属板の両面から前記濾室内のケーキに伝熱されて加温される，ことを特徴とする乾燥機能付きフィルタプレス装置用の加温板が提供される。   In order to solve the above-mentioned problems, in the first aspect of the present invention, filter plates and heating plates are alternately arranged, and a filter chamber is provided between the opposing filter plates and the heating plate via a filter cloth. The heating plate used in a filter press device with a drying function that is formed and capable of drying while heating the cake dehydrated in the filter chamber with the heating plate, The heating plate has a three-layer structure for the flow path of the heating medium, and is formed by bonding metal plates of a predetermined thickness on both sides of the missing resin plate. When the heating medium passes through the heating medium flow passage formed by the metal plate, heat is transferred from both sides of the metal plate to the cake in the filter chamber and heated. A heating plate for a filter press device with a drying function is provided.

上記記載の発明では，温水流通路形成領域を予め欠損させた樹脂板と金属板とを張り合わせるだけで，簡易かつ容易に加温板を作製することができる。このように，加温板の温水流通路を簡易かつ容易に形成することができるので，金属一体型の加温板と比較して加温板の製造時間が著しく短縮される。さらに，原材料費が著しく低減されるので，製造時間の短縮による効果と共に，加温板を安価で提供することができる。また，樹脂板の所定部分を切り取った後，あるいは所定形状の樹脂板を組み合わせた後，その両面に金属板を張り合わせるだけで加温媒体の流通路を形成することができるので，加温媒体流通路の設計の自由度を増すことができる。さらに，加温板の軽量化を図ることができるので，加温板を比較的容易に運搬することができる。   In the above-described invention, the heating plate can be easily and easily produced simply by pasting together the resin plate and the metal plate in which the hot water flow passage forming region is previously lost. As described above, since the warm water flow passage of the heating plate can be easily and easily formed, the manufacturing time of the heating plate is remarkably shortened as compared with the metal integrated heating plate. Furthermore, since the raw material cost is significantly reduced, the heating plate can be provided at a low cost with the effect of shortening the manufacturing time. In addition, after cutting out a predetermined portion of the resin plate or combining the resin plates having a predetermined shape, the flow path of the heating medium can be formed by simply bonding the metal plates to both sides of the resin plate. The degree of freedom in designing the flow path can be increased. Furthermore, since the weight of the heating plate can be reduced, the heating plate can be transported relatively easily.

また，前記金属板は，ステンレス製板である，如く構成すれば，例えばＳＵＳ３０４製のステンレス板を使用すれば，熱伝導性，耐食性に優れる材料として，比較的安価に提供することができる。   Further, if the metal plate is made of a stainless steel plate, for example, if a stainless steel plate made of SUS304 is used, it can be provided as a material having excellent thermal conductivity and corrosion resistance at a relatively low cost.

また，前記樹脂板は，ポリプロピレン製板である，如く構成すれば，通常，濾板として使用されるポリプロピレン製濾板と同じ材質であるので，材料強度が同一であり，フィルタプレス装置の加圧（例えば，３０〜５０ｋｇｆ／ｃｍ２の圧力）時に破損することが防止される。   Further, if the resin plate is made of polypropylene, the resin plate is usually made of the same material as the polypropylene filter plate used as the filter plate. It is prevented from being damaged at the time (for example, a pressure of 30 to 50 kgf / cm 2).

また，前記加温媒体は，温水または水蒸気からなる，如く構成すれば，例えば工場内の余剰温水や，余剰水蒸気を使用することができるので，ケーキの乾燥処理コストの低減を図ることができる。   Further, if the heating medium is composed of warm water or steam, for example, surplus warm water in the factory or surplus steam can be used, the cost of cake drying treatment can be reduced.

乾燥機能を付加したフィルタプレス装置で使用される加温板の温水通路孔を簡易かつ容易に形成することができる。また，加温板を安価で提供することができる。   It is possible to easily and easily form the hot water passage hole of the heating plate used in the filter press apparatus to which the drying function is added. In addition, the heating plate can be provided at a low cost.

以下に添付図面を参照しながら，本発明の好適な実施の形態について詳細に説明する。なお，本明細書及び図面において，実質的に同一の機能構成を有する構成要素については，同一の符号を付することにより重複説明を省略する。   Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the present specification and drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

まず，図１及び図２に基づいて，本実施形態にかかる加温板が使用される乾燥機能付きフィルタプレスの構成について説明する。なお，図１は，本実施形態にかかる加温板が使用される乾燥機能付きフィルタプレス装置の構成を示す説明図である。図２は，本実施形態にかかる加温板が使用される乾燥機能付きフィルタプレス装置の要部構成を示す説明図である。   First, based on FIG.1 and FIG.2, the structure of the filter press with a drying function in which the heating board concerning this embodiment is used is demonstrated. In addition, FIG. 1 is explanatory drawing which shows the structure of the filter press apparatus with a drying function in which the heating board concerning this embodiment is used. FIG. 2 is an explanatory diagram showing a main configuration of a filter press device with a drying function in which the heating plate according to the present embodiment is used.

なお，本実施形態にかかる乾燥機能付きフィルタプレス装置においては，加温板以外の構成は，従来と同様であるので，その詳しい説明は省略し，簡易な説明に留める。 In addition, in the filter press apparatus with a drying function concerning this embodiment, since structures other than a heating board are the same as the past, the detailed description is abbreviate | omitted and only a simple description is given.

まず，図１及び図２に示すように，本実施形態にかかる加温板２００が使用される乾燥機能を有するフィルタプレス装置１０においては，複数の濾板１００と加温板２００とが交互に配置されている。また，隣接する濾板１００と加温板２００との間には，スラリーを脱水するための濾布７００により囲まれた濾室３００が形成されている。スラリーは，スラリー供給ポンプ（図示せず）によって原液供給口４００からフィルタプレス装置１０に供給されて濾過された後，濾液が濾液排出口５００から排出される。 First, as shown in FIG.1 and FIG.2, in the filter press apparatus 10 which has the drying function in which the heating plate 200 concerning this embodiment is used, the several filter plate 100 and the heating plate 200 are alternated. Has been placed. A filter chamber 300 surrounded by a filter cloth 700 for dewatering the slurry is formed between the adjacent filter plate 100 and the heating plate 200. The slurry is supplied to the filter press device 10 from the stock solution supply port 400 by a slurry supply pump (not shown) and filtered, and then the filtrate is discharged from the filtrate discharge port 500.

また，図２に示すように，本実施形態にかかる濾板１００は，その両側面に張設されたダイヤフラム（圧搾膜）６００を備えている。なお，濾板１００とダイヤフラム６００は一体に構成され，プレート自体がダイヤフラムの機能を有していても構わない。かかるダイヤフラムは，伝熱性を高めるため塩化ポリエチレンを主成分とした架橋ゴムを使用することができる。また，クロロスルホン化ポリエチレン等の架橋ゴム生成可能なポリエチレン素材を使用することもできる。 Further, as shown in FIG. 2, the filter plate 100 according to the present embodiment includes a diaphragm (pressed membrane) 600 stretched on both side surfaces thereof. Note that the filter plate 100 and the diaphragm 600 may be integrally formed, and the plate itself may have a diaphragm function. Such a diaphragm can use a crosslinked rubber containing chlorinated polyethylene as a main component in order to enhance heat transfer. Also, a polyethylene material capable of forming a crosslinked rubber such as chlorosulfonated polyethylene can be used.

本実施形態にかかる乾燥機能付きフィルタプレス装置１０の各濾室３００は，加温板２００に支持された濾布７００と，ダイヤフラム６００に支持された濾布７００との内部空間として配置されている。なお，濾板１００及び加温板２００には，スラリー注入孔４００に対応した箇所に孔が形成されており，この孔によってスラリーが通過されて，各濾室３００にスラリーが供給される。 Each filter chamber 300 of the filter press device 10 with a drying function according to the present embodiment is arranged as an internal space between the filter cloth 700 supported by the heating plate 200 and the filter cloth 700 supported by the diaphragm 600. . Note that holes are formed in the filter plate 100 and the heating plate 200 at locations corresponding to the slurry injection holes 400, and the slurry passes through the holes and is supplied to the filter chambers 300.

上記乾燥機能付きフィルタプレス装置１０においては，スラリー供給ポンプでスラリーを圧送して濾過が行われた後，濾板１００と加温板２００との間に設けられたダイヤフラム内に圧搾水を圧送して膨張させてスラリーを圧搾脱水する。 In the filter press device 10 with a drying function, after the slurry is pumped and filtered by the slurry supply pump, the compressed water is pumped into the diaphragm provided between the filter plate 100 and the heating plate 200. Then, the slurry is squeezed and dehydrated.

その後，固形分の塊となったケーキに対して，真空ポンプにより吸引して水分の蒸発温度を下げた上で，ダイヤフラム６００内に例えば温水を圧送して膨張させると共に，加温板２００にも温水を圧送して濾室３００内のケーキを加温する。このことにより，濾室内のケーキは，水分の蒸発温度が下げられた上で加温されるので，効果的にケーキを乾燥することができる。なお，このときの濾室外の減圧圧力は低ければ低いほどよい。また，温水として，例えば工場内の余剰温水を使用すれば，ケーキの乾燥処理コストの低減を図ることができる。 Thereafter, the cake that has become a lump of solid content is sucked by a vacuum pump to lower the evaporation temperature of the water, and then, for example, hot water is pumped into the diaphragm 600 to be expanded, and the heating plate 200 is also expanded. Hot water is pumped to heat the cake in the filter chamber 300. As a result, the cake in the filter chamber is heated after the evaporation temperature of the water is lowered, so that the cake can be effectively dried. At this time, the lower the pressure outside the filter chamber, the better. Further, if, for example, surplus hot water in the factory is used as the hot water, the cost for drying the cake can be reduced.

ケーキの乾燥終了後には，開枠してケーキ排出工程を行なってケーキを排出する。ケーキは乾燥状態であるため，剥離性は良好であり，粒子状となって剥離し濾布に残留するケーキはほとんどない。 After drying the cake, open the frame and perform the cake discharging process to discharge the cake. Since the cake is in a dry state, the peelability is good, and there is almost no cake that is separated into particles and remains on the filter cloth.

次に，図３に基づいて，本実施形態にかかる加温板２００の構成について説明する。なお，図３（ａ）は，本実施形態にかかる加温板２００の構成を示す正面図である。図３（ｂ）は，本実施形態にかかる加温板２００の構成を示す側面図である。 Next, based on FIG. 3, the structure of the heating board 200 concerning this embodiment is demonstrated. FIG. 3A is a front view showing the configuration of the heating plate 200 according to the present embodiment. FIG.3 (b) is a side view which shows the structure of the heating board 200 concerning this embodiment.

本実施形態にかかる加温板は，図３に示すように，一部を切り欠いて加温媒体の流通路２２０の形成予定領域が欠損された所定厚さ（例えば，２５ｍｍ厚さ）の樹脂板２００ｂと，樹脂板２００ｂの両面に張り合わされた所定厚さ（例えば，１ｍｍ厚さ）の金属板２００ａ，２００ｃと，からなる３層構造を有する。 As shown in FIG. 3, the heating plate according to the present embodiment is a resin having a predetermined thickness (for example, 25 mm thickness) in which a part of the heating medium flow path 220 to be formed is missing. It has a three-layer structure including a plate 200b and metal plates 200a and 200c having a predetermined thickness (for example, 1 mm thickness) bonded to both surfaces of the resin plate 200b.

加温板２００の中央付近には，スラリーを供給する原液供給口２４０が形成されており，その四隅には濾液排出口２５０が形成されている。また，加温板２００の左側部下方には，温水入口２１０が形成されており，例えば９０℃程度の温水が加温板内部に流入される。加温板内部に流入した温水は，加温板２００の内部に形成された温水流通路２２０を通過して，加温板２００の上方に形成された温水出口２３０から外部に排出される。かかる温水の流通路２２０は，加温板両面の濾室に対応する箇所に熱が行き渡るように加温板全体に形成されており，温水が温水流通路２２０を通過することにより，温水の熱が両側の金属板２００ａ，２００ｃからケーキに伝熱されて加温される。 Near the center of the heating plate 200, a stock solution supply port 240 for supplying slurry is formed, and filtrate discharge ports 250 are formed at four corners thereof. A warm water inlet 210 is formed below the left side of the warming plate 200, for example, warm water of about 90 ° C. flows into the warming plate. The warm water flowing into the warming plate passes through the warm water flow passage 220 formed inside the warming plate 200 and is discharged to the outside from the warm water outlet 230 formed above the warming plate 200. The warm water flow passage 220 is formed in the entire heating plate so that heat is distributed to the locations corresponding to the filter chambers on both sides of the heating plate, and the hot water passes through the warm water flow passage 220, so Is transferred from the metal plates 200a and 200c on both sides to the cake and heated.

上記構成の加温板は，温水通路孔を簡易かつ容易に形成することができるので，加温板を安価で提供することができる。また，金属板として，例えばＳＵＳ３０４製のステンレス板を使用するので，熱伝導性，耐食性に優れる材料として，比較的安価に提供することができる。また，樹脂板として，通常，濾板として使用されるポリプロピレン製と同じ材質であるので，材料強度が同一であり，フィルタプレス装置の加圧（例えば，３０〜５０ｋｇｆ／ｃｍ２の圧力）時に破損することが防止される。   Since the warming plate having the above configuration can easily and easily form the hot water passage hole, the warming plate can be provided at a low cost. Further, since a stainless steel plate made of, for example, SUS304 is used as the metal plate, it can be provided at a relatively low cost as a material excellent in thermal conductivity and corrosion resistance. Also, since the resin plate is usually the same material as the polypropylene used as the filter plate, the material strength is the same, and it is damaged when the filter press device is pressurized (for example, a pressure of 30 to 50 kgf / cm 2). It is prevented.

次に，図４に基づいて，本実施形態にかかる加温板２００の製造方法を説明する。なお，図４は，本実施形態にかかる加温板２００の製造方法を示すフローチャートである。 Next, a method for manufacturing the heating plate 200 according to the present embodiment will be described based on FIG. In addition, FIG. 4 is a flowchart which shows the manufacturing method of the heating board 200 concerning this embodiment.

まず，ステップＳ１０２で，２枚のステンレス板（例えば厚さ１ｍｍ，ＳＵＳ３０４）を所定形状に加工する（ステップＳ１０２）。なお，ステンレス板の厚さは，腐食しろ等を考慮して決定することができる。 First, in step S102, two stainless plates (eg, 1 mm thick, SUS304) are processed into a predetermined shape (step S102). Note that the thickness of the stainless steel plate can be determined in consideration of corrosion allowance and the like.

別途に，ステップＳ１０４で，所定厚さ（例えば，厚さ２５ｍｍ）の樹脂板（例えばポリプロピレン製板）の温水流通路形成領域を切り欠き加工し，所定形状に加工する（ステップＳ１０４）。 Separately, in step S104, a hot water flow passage forming region of a resin plate (for example, a polypropylene plate) having a predetermined thickness (for example, 25 mm thick) is cut and processed into a predetermined shape (step S104).

次いで，ステップＳ１０６で，１枚のステンレス板２００ａに，加工した樹脂板２００ｂを接着剤を使用して貼り付ける（ステップＳ１０６）。   Next, in step S106, the processed resin plate 200b is attached to one stainless plate 200a using an adhesive (step S106).

最後に，ステップＳ１０８で，ステンレス板２００ａに貼り付けられた樹脂板２００ｂ上に，他のステンレス板２００ｃを接着剤を使用して張り付ける（ステップＳ１０８）。 Finally, in step S108, another stainless steel plate 200c is pasted on the resin plate 200b attached to the stainless steel plate 200a using an adhesive (step S108).

本実施形態にかかる加温板においては，加温板の温水流通路を簡易かつ容易に形成することができるので，金属一体型の加温板と比較して加温板の製造時間が著しく短縮される。さらに，原材料費が著しく低減されるので，製造時間の短縮による効果と共に，加温板を安価で提供することができる。また，樹脂板の所定部分を切り取った後，あるいは所定形状の樹脂板を組み合わせた後，その両面に金属板を張り合わせるだけで加温媒体の流通路を形成することができるので，加温媒体流通路の設計の自由度を増すことができる。さらに，加温板の軽量化を図ることができるので，加温板を比較的容易に運搬することができる。 In the heating plate according to this embodiment, the warm water flow passage of the heating plate can be easily and easily formed, so that the manufacturing time of the heating plate is remarkably shortened as compared with the metal integrated heating plate. Is done. Furthermore, since the raw material cost is significantly reduced, the heating plate can be provided at a low cost with the effect of shortening the manufacturing time. In addition, after cutting out a predetermined portion of the resin plate or combining the resin plates having a predetermined shape, the flow path of the heating medium can be formed by simply bonding the metal plates to both sides of the resin plate. The degree of freedom in designing the flow path can be increased. Furthermore, since the weight of the heating plate can be reduced, the heating plate can be transported relatively easily.

上記実施形態に基づいて，本発明にかかる３層構造の加温板を作成したので，従来の金属製一体構造の加温板と比較して具体的に説明する。   Based on the above embodiment, the heating plate having a three-layer structure according to the present invention is prepared, and will be specifically described in comparison with a conventional heating plate having a metal integrated structure.
