Description
本発明は、原材料が非木材によるパルプ製造において、前処理等を加えることによって、連続的に、より短時間、安価に、しかも水の使用量、薬品の使用量を大幅に削減できる非木材によるパルプ製造方法及びパルプ製造システム装置に関するものである。 The present invention is based on non-wood that can significantly reduce the amount of water and chemicals used continuously, in a shorter time, at a lower cost by adding pretreatment in pulp production using non-wood as a raw material. The present invention relates to a pulp manufacturing method and a pulp manufacturing system apparatus.
従来の技術としては、繊維以外の不純物を取り除きパルプ化するためにバッチ式と呼ばれる巨大な蒸気釜に不純物の含まれた原材料を入れ、大量の薬品で長時間煮るなどの処理を行い、不純物を取り除きパルプ化するという処理を行う方法や、原材料が非木材によるパルプ製造システム装置の前処理装置において、原材料である非木材が筒体を流動するようにし、該筒体内を貫通する回転軸を設け、該回転軸には独立の駆動装置を持つと共に、前記回転軸の軸方向の半分に螺旋状旋回翼群を取付け、前記回転軸の軸方向の残りの部分に交差状に破砕刃を設けたニーディング刃をブロックごとに嵌め込み式で交換自在に取り付けた攪拌、洗浄、圧縮、脱水、発熱、破砕を行う装置で、旋回翼群の回転と蒸気を補助的に使って強制的に破砕と、もむ作用によって高発熱させ、少量の薬品で繊維以外の不純物をより効率的に除きパルプ化する前処理装置で非木材を洗いながらこなし、その後、前処理された非木材を複数本の筒体間に流して流動し、該複数本の各筒体内を貫通する各回転軸を設け、該各回転軸は各独立の駆動装置を持つと共に、螺旋状旋回翼郡を取付け、さらに残りの部分に交差状に破砕刃を設けたニーディング刃をブロックごとに嵌め込み式で交換自在に取り付けた攪拌、洗浄、圧縮、脱水、発熱、破砕を行う多段式パルプ製造機を通し、漂白剤を投入して漂白を行うことで連続的に、短時間、安価に非木材のパルプ化を行うことができる非木材によるパルプ製造システム装置（例えば、特許文献１参照）が存在している。 As a conventional technology, in order to remove impurities other than fibers and make pulp, a raw material containing impurities is put into a huge steam pot called a batch type, and processing such as boiling for a long time with a large amount of chemicals is performed to remove impurities. In a method of removing pulp and a pre-processing device of a pulp production system device using non-wood as a raw material, the non-wood as a raw material flows through the cylinder, and a rotating shaft that penetrates the cylinder is provided. The rotating shaft has an independent driving device, and a spiral swirl blade group is attached to the half of the rotating shaft in the axial direction, and a crushing blade is provided in a crossing manner in the remaining portion of the rotating shaft in the axial direction. A kneading blade is inserted into each block and is exchangeable, and it is an agitation, washing, compression, dehydration, heat generation, and crushing device that uses the rotation of swirl blades and steam to assist crushing. Also The heat is generated by the action, and the non-wood is washed with a pre-treatment device that removes impurities other than fibers more efficiently with a small amount of chemicals, and then pulped, and then the pre-treated non-wood is placed between multiple cylinders. Each rotating shaft is provided to flow through and flow through each of the plurality of cylinders, and each rotating shaft has an independent driving device and is attached with a spiral swirl blade group, and further intersects with the remaining portion. A kneading blade with a crushing blade fitted into each block is inserted into each block and exchangeably attached, and then passed through a multistage pulp manufacturing machine that performs stirring, washing, compression, dehydration, heat generation, crushing, and bleaching is performed by introducing bleach There is a non-wood pulp manufacturing system apparatus (for example, see Patent Document 1) that can continuously and inexpensively pulp non-wood by performing it.
しかしながら、前記従来技術においては、巨大な蒸気釜で長時間煮るという時間的な損失、さらに巨大な蒸気釜を使用しなければ大量に処理ができないという場所等の問題、さらに大量の薬品で長時間煮ることによって生じる廃液の処理という問題点があった。
また、原材料が稲、小麦、大麦、ライ麦等の藁、アシ類、バガス、竹、麻、ケナフ、道路に生息する雑草等、非木材であると、葉っぱ、ゴミ、砂、シリカ等、種々雑多な汚れと共に、繊維以外の不純物が存在しているので、これを水分を投入しながら薬品を使用せず、原材料の非木材の汚れを取る必要がある。原材料である非木材が筒体内を流動するようにし、該筒体内を貫通する回転軸を設け、該回転軸には独立の駆動装置を持つと共に、前記回転軸の軸方向の半分に螺旋状旋回翼群を取り付け、前記回転軸の軸方向の残りの部分に交差状に破砕刃を設けたニーディング刃をブロックごとに嵌め込み式で交換自在に取り付けた攪拌、洗浄、圧縮、脱水、発熱、破砕を行う装置で、旋回翼群の回転と蒸気を補助的に使って強制的に破砕ともむ作用によって、高発熱させる粗ごなし前処理装置で処理し、水分と汚れだけ排除し、次段装置の多段式パルプ製造機に汚れを取った非木材の原材料と苛性ソーダを投入してパルプ化するが、水を加えるとパルプ化できないことが判明した。
また、装置内の原材料の送りに関しては、多段式パルプ製造機の最上段筒体から中段筒体、さらに中段筒体から最下段筒体を継ぐ連通筒体は単に垂直か傾斜していて、特に送るための機構はない。このことにより、現実に原材料がつまって送られなくなってしまうことが判明した。
本発明は、このような事情に鑑み、非木材の原材料をパルプ化するための手段として筒体内を貫通する回転軸の軸方向の約半分に亘り、螺旋状旋回翼群を取り付け、残り後半部分に回転軸の円周方向に対して、適宜角度で傾斜させて回転軸に直交するように一枚毎交互に向きを反転させて取り付けられた破砕刃を設けたニーディング刃をブロックごとに嵌め込み式で交換自在に取り付けた筒体内を原材料が流動するようにした攪拌、洗浄、圧縮、脱水、発熱、破砕を行う粗ごなし前処理装置と、同様の筒体を複数本有する多段式パルプ製造機に苛性ソーダを少量加え、短時間で安価に非木材のパルプ化を行うことができる非木材によるパルプ製造方法及びパルプ製造システム装置を提供することを目的とするものである。
However, in the above prior art, there is a time loss of boiling in a huge steam kettle for a long time, a problem such as a place where a large amount of processing cannot be performed without using a huge steam kettle, and a long time with a large amount of chemicals. There was a problem of treatment of the waste liquid generated by boiling.
In addition, if the raw material is non-wood such as rice, wheat, barley, rye, etc., reeds, bagasse, bamboo, hemp, kenaf, weeds that inhabit roads, leaves, garbage, sand, silica, etc. Since impurities other than fibers are present along with the soiling, it is necessary to remove the soiling of non-wood as a raw material without using chemicals while adding moisture. A non-wood as a raw material flows in the cylinder, and a rotating shaft that penetrates the cylinder is provided. The rotating shaft has an independent driving device and spirally rotates in half of the axial direction of the rotating shaft. Agitating, washing, compressing, dehydrating, exothermic, and crushing with a blade group attached and a kneading blade with a crushing blade crossed at the remaining part of the axis of rotation of the rotary shaft, fitted into each block and attached interchangeably This is a device that performs the process with a coarse pretreatment device that generates high heat by forcibly crushing with the rotation of the swirl blade group and steam, and removing only moisture and dirt. It turned out that pulp was made by adding non-wood raw materials and caustic soda that were soiled to a multi-stage pulp making machine, but when water was added, it could not be pulped.
Regarding the feed of raw materials in the apparatus, the communicating cylinder that connects the uppermost cylinder to the middle cylinder, and further the middle cylinder to the lowermost cylinder of the multistage pulp making machine is simply vertical or inclined, There is no mechanism for sending. As a result, it was found that the raw materials were actually jammed and could not be sent.
In view of such circumstances, the present invention attaches a spiral swirl blade group as a means for pulping non-wood raw materials over about half of the axial direction of the rotating shaft passing through the cylinder, and the remaining second half portion. Insert a kneading blade with a crushing blade that is tilted at an appropriate angle with respect to the circumferential direction of the rotating shaft and reversely turned one by one so as to be orthogonal to the rotating shaft for each block. Multi-stage pulp manufacturing with a plurality of similar cylinders and a coarse pre-treatment device that stirs, cleans, compresses, dehydrates, generates heat, and crushes so that raw materials flow in cylinders that are interchangeably installed It is an object of the present invention to provide a non-wood pulp manufacturing method and a pulp manufacturing system apparatus capable of adding a small amount of caustic soda to a machine and performing non-wood pulping at low cost in a short time.

Since the raw material which concerns on this invention has the structure as the said description, the pulp manufacturing method and pulp manufacturing system apparatus by a non-wood have the effect described below.
(1) A spiral swirling blade group and a crushing blade were provided while adding water to remove various impurities such as leaves, dust, sand and silica contained in non-wood raw materials and impurities other than fibers. The non-wood raw material removed by the coarse pretreatment device consisting of a kneading blade was found to be unable to be pulped while supplying water. The pulping is performed by the kneading blade provided with the spiral swirl blade group and the crushing blade without supplying water, but the problem is that the raw material becomes tangled and transported by the communicating cylinder that connects the cylinders of each stage Can be continuously pulped.

生産地から直接集荷された汚れのついた稲、小麦、大麦、ライ麦等の藁、アシ類、バガス、竹、麻、ケナフ、道路沿いに生息する雑草等の非木材を使用するため、汚れを取り除く必要がある。本発明は、汚れと共に繊維以外の不純物を取り除くため、水を加えながら螺旋状旋回翼群と交叉状に破砕刃を設けたニーディング刃をブロックごとに嵌め込み式で交換自在に取り付けた筒体内に非木材の原材料を投入して、流動するようにして攪拌、洗浄、圧縮、脱水、発熱、破砕を行う粗ごなし前処理装置を有し、この前処理装置から不純物を取り除いた非木材を多段式パルプ製造機に投入する。この多段式パルプ製造機は、コンパクト化を考慮するために多段式に分け、最上方筒体の右側から入れた非木材を処理しながら左側に送り、中間筒体に移送し、中間筒体内を左から右におくり、さらに同様に最下方筒体の右から左に移動させ、反転を繰り返しながら処理を行うもので、最上段筒体から中段筒体、さらに中段筒体から最下段筒体に原材料を移送させる連通筒体が設けられている。この連通筒体に各段筒体の螺旋状旋回翼群、破砕刃を設けたニーディング刃を避けてなるべく凹部を形成しないように各段筒体から連通筒体に連続してビニール系の樹脂及びカーボンを含有した樹脂を除いた高分子板で覆ったことで原材料の絡まりや詰まりを防止することができ、従来長い距離を必要とするパルプ製造工程を短く構成できるようにした多段式パルプ製造機に送り、そこで処理を行った後、漂白のために、苛性ソーダ等の薬品を加え、非木材によるパルプを製造する製造方法及びパルプ製造システム装置を得たものである。 Use non-wood such as rice, wheat, barley, rye, etc., collected directly from the production area, non-wood such as reeds, bagasse, bamboo, hemp, kenaf and weeds that live along the road. It needs to be removed. In the present invention, in order to remove impurities other than fibers together with dirt, a kneading blade provided with a crushing blade in a cross shape with a spiral swirl blade group while adding water is fitted into each block so as to be interchangeably attached to each block. It has a coarse pretreatment device that adds non-wood raw materials and stirs, cleans, compresses, dehydrates, generates heat, and crushes them in a fluidized manner, and removes impurities from this pretreatment device in multiple stages.

In order to avoid the kneading blade provided with the spiral swirl blade group and crushing blade of each step cylinder in this communication cylinder, a vinyl resin is continuously formed from each step cylinder to the communication cylinder. Multi-stage pulp manufacturing that can prevent entanglement and clogging of raw materials by covering with a polymer plate excluding resin containing carbon and carbon, and can shorten the conventional pulp manufacturing process that requires a long distance After being sent to the machine and processed there, a chemical such as caustic soda is added for bleaching to obtain a production method and a pulp production system device for producing pulp made of non-wood.
以下、本発明の一実施例を添付図面で詳細に説明する。
先ず、本発明の原料である非木材から葉っぱ、ゴミ、砂、シリカ等の種々雑多な汚れ、及び繊維以外の不純物を取り除く粗ごなし前処理装置について詳細に説明する。
従来の方法としては、バッチ方式と呼ばれる蒸気釜を使用し、大量の薬品と共に非木材を長時間釜で煮る方法が採られている。
しかし、この方法は大量の薬品で長時間釜により煮るために処理途中で非常に濃い排液が出てしまう。
Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
First, a rough pretreatment apparatus for removing various impurities such as leaves, dust, sand, silica, and impurities other than fibers from non-wood, which is a raw material of the present invention, will be described in detail.
As a conventional method, a steam pot called a batch method is used, and a method of boiling non-wood with a large amount of chemicals in a kettle for a long time is employed.
However, since this method simmers in a kettle for a long time with a large amount of chemicals, a very concentrated drainage is produced during the treatment.
そこで、本発明の粗ごなし前処理装置４では水を供給しながら筒体内を貫通する回転軸の軸方向の約半分に亘り、螺旋状旋回翼群１を取り付け、前記回転軸の軸方向の残り後半部分に回転軸の円周方向に対して、適宜角度で傾斜させて回転軸の軸方向に直交するように一枚毎交互に向きを反転させて交叉状に取り付けられた破砕刃２を設けたニーディング刃３をブロックごとに嵌め込み式で交換自在に取り付けた筒体に原材料を流動するようにし、攪拌、洗浄、圧縮、脱水、発熱、破砕を行うため、投入された非木材が装置内で洗いながら螺旋状旋回翼群１、ニーディング刃３で強制的に攪拌、洗浄、圧縮、脱水、発熱、破砕される。この際、摩擦により非木材が熱を発生するため、従来のバッチ式で使用するパルプ化用蒸煮スチームを必要とせず、その際に使用するアルカリ剤等の薬品が従来の十分の一から十五分の一という少量の薬品で、短時間で汚れ、不純物を取り除くものである。
Therefore, in the
次に、粗ごなし前処理装置４を加えた非木材によるパルプ製造システム装置について詳細に説明する。
従来の非木材等のパルプ製造では、まずバッチ方式で長時間蒸気釜で煮て繊維以外の不純物を取り除き、パルプの製造に必要なたくさんの工程を巨大なシステム装置を用いて行う必要があり、非木材等のパルプ製造を行うには、巨大な敷地と、多量のランニングコストが必要であった。
また、前記粗ごなし前処理装置にて前処理された非木材の原材料を次の工程である多段式パルプ製造機でパルプ化する際、水を供給すると、パルプ化することができないことが判明した。
Next, the non-wood pulp manufacturing system apparatus to which the
In conventional pulp production such as non-wood, it is necessary to remove impurities other than fiber by boiling in a batch method for a long time, and to perform many processes necessary for pulp production using a huge system device, In order to manufacture pulp such as non-wood, a huge site and a large amount of running costs were required.
In addition, when pulping non-wood raw material pretreated by the coarse pretreatment apparatus with a multi-stage pulp manufacturing machine, which is the next step, it turns out that it cannot be pulped if water is supplied. did.
理由しては、多段式パルプ製造機の各段の筒体は、前記粗ごなし前処理装置と同様に螺旋状旋回翼群１、破砕刃２を設けたニーディング刃３によって筒体内を攪拌、圧縮、発熱、破砕を行い、移送させる構成になっているが、各段の最上段筒体から中段筒体、中段筒体から最下段筒体へと原材料を移送して連絡する連通筒体は単に筒体で連結しており、この筒体はステンレス筒で形成されているが、水を供給しながらでないため、非木材の原材料が引っかかったように詰まってしまい、次段の筒体に移送されない現象が発生してしまう。
そのため、種々解決手段を試みたところ、例えばビニール系樹脂、カーボンを含有した樹脂では全て原材料が詰まってしまうことが判明した。
そして、本発明では、貼り付け易く、形成し易い厚さのビニール系樹脂、カーボンを含有した樹脂を除く高分子板１６で覆うことで詰まりを解消することに成功した。
この高分子板１６の貼り付けも、各段における筒体の螺旋状旋回翼群１、破砕刃２を有するニーディング刃３の端部である刃の切れ目近傍１７から、刃の回転を邪魔しない程度にできるだけ凹部を形成しないように連通筒体９、１１全体と各段の筒体８、１０、１３に折り返して覆うように貼り付けることで詰まりを無くすことができたものである。
このような構成を採用することで、本発明のパルプ製造システム装置は、非木材の汚れや、繊維以外の不純物を前記本発明の粗ごなし前処理装置４で取り除き、数段からなる筒体内において、右側から入れた非木材を加工しながら左側に圧送し、排出されたものを左から右に圧送するというように、反転を繰り返しながら攪拌、圧縮、脱水、発熱、破砕を行う多段式パルプ製造機５を用いることで、従来の非木材パルプよりも質の良い非木材パルプが製造でき、また、薬品の使用を必要最小限にすることができ、それに伴い、排液処理などの問題も解決し、パルプ製造システム装置のコンパクト化、ランニングコストの低下と、顕著な効果が得られるものである。
The reason is that the cylinders at each stage of the multistage pulp making machine are stirred in the cylinders by the
For this reason, when various solutions were tried, it was found that, for example, vinyl-based resins and carbon-containing resins were all clogged with raw materials.
And in this invention, it succeeded in eliminating clogging by covering with the
The affixing of the
By adopting such a configuration, the pulp production system apparatus of the present invention removes dirt other than non-wood and impurities other than fibers by the
本発明の一実施例であるパルプ製造システム装置について詳細に説明すると、側面から見て略三角形状になるように配設した３本の筒体からなり、粗ごなし前処理装置により送られる非木材原材料を最上段筒体８の原料投入口７から投入するものである。この３本の筒体は、原料投入口７を一端に備えた最上段筒体８の原料投入口７とは反対側に前記最上段筒体８と連通する第１連通筒体９を備え、この第１連通筒体９を中段筒体１０の一端部に連通設置し、さらに、この中段筒体１０に連通した第１連通筒体９とは反対側に最下段筒体１３に連通するための第２連通筒体１１を設け、この第２連通筒体１１が最下段筒体１３の一端部に連通設置され、製品排出口１２が最下段筒体１３の第２連通筒体１１とは反対側に設けられている。この各筒体８、１０、１３の連通筒体９、１１が、最上段筒体８から中段筒体１０、中段筒体１０から最下段筒体１３に流れる際、流れ方向はその度に反転することになる。この各筒体８、１０、１３内を貫通する回転軸14が、それぞれ独立の駆動装置５（例えばギャードモータ等）で回転駆動するように設けられている。また、前記各筒体８、１０、１３の配置は、側面から見て図のようなものだけでなく、縦に垂直に設けたり、正三角形になるようにしたり、横に水平に並べたり、建屋、関連機器との配置の都合により、種々設計変更ができることはいうまでもない。さらに、原料投入口１、各連通筒体９、１１、製品排出口１２の取り付け位置も効率を考慮した上で適宜の配置ができることはいうまでもない。そして、各筒体の本数も複数本適宜選択できるもので、多段式パルプ製造機５を用いることで非木材等の原料が摩擦により熱を発生するためパルプ化用蒸煮スチームが必要なくなり、さらに安価にパルプを製造することができる。
The pulp manufacturing system apparatus according to an embodiment of the present invention will be described in detail. The pulp manufacturing system apparatus is composed of three cylinders arranged so as to have a substantially triangular shape when viewed from the side, and is sent by a coarse pretreatment apparatus. The wood raw material is fed from the
そして、最後にパルプにリグニン等の繊維と繊維をつなぐ接着剤のような物質が含まれている。このリグニンが結果的にパルプに色を着けたり、繊維を硬直化すると共に水和性を失わせることになる。従って、それを除去するために螺旋状旋回翼群により攪拌、さらに漂白筒６を経る際、オゾン及び苛性ソーダ等を投入して白色に漂白し、パルプ製造が完成するというパルプ製造システム装置である。 Finally, the pulp contains a substance such as an adhesive that connects the fibers with fibers such as lignin. This lignin will eventually color the pulp, stiffen the fibers and lose hydration. Therefore, in order to remove it, it is a pulp production system apparatus in which the pulp is completed by stirring with a spiral swirl blade group and further bleaching white by adding ozone and caustic soda when passing through the bleaching cylinder 6.
非木材の原材料だけでなく、通常の製紙材料を使用してパルプ製造を行うこともできる。 Pulp can be produced using not only non-wood raw materials but also ordinary papermaking materials.
