Definitions

  • the present invention relates to a means for separating a solid polymer dispersed in a liquid from the liquid.
  • a vapor is allowed to act on a polymer (generally a polymer material) dissolved in a solvent to remove the solvent from the polymer. Thereafter, the polymer is crushed by a crusher to form a small solid lump (solid polymer, called crumb).

  • the crumb is then separated from the hot water. Then, necessary dehydration and drying are performed on the extracted crumb. Then, if the crumb is press-molded, a block-shaped rubber material (intermediate product) is obtained.

Description

固体状重合体用分離装置Separator for solid polymer
 本発明は、液中に分散した固体状重合体を、その液から分離する手段に関する。 The present invention relates to a means for separating a solid polymer dispersed in a liquid from the liquid.
 化学工業、食品工業、鉱工業等の分野では、液中に分散した固体(例えば粒子状の固体等)を、その液から分離し、その固体を取り出す工程が、多く存在する。 In the fields of chemical industry, food industry, mining industry, etc., there are many steps of separating a solid dispersed in a liquid (for example, a particulate solid) from the liquid and taking out the solid.
 例えば、化学工業の分野では、ゴム製品の製造過程において、溶媒中に溶解した重合体(一般に高分子材料)に蒸気を作用させ、重合体から溶媒を除去する。その後、この重合体を、破砕機で破砕して、固体の小さい塊(固体状重合体、これをクラムとよぶ)にしている。ここで、クラムは(固体状重合体は)蒸気により加温された熱湯中(液中)に分散した状態となっている。その後、クラムを熱湯から分離する。そして、取り出したクラムに対し、更に必要な脱水・乾燥を行う。その後、クラムをプレス成形すれば、ブロック状ゴム素材(中間製品)が得られる。 For example, in the field of chemical industry, in the process of manufacturing rubber products, a vapor is allowed to act on a polymer (generally a polymer material) dissolved in a solvent to remove the solvent from the polymer. Thereafter, the polymer is crushed by a crusher to form a small solid lump (solid polymer, called crumb). Here, the crumbs (solid polymer) are dispersed in hot water (liquid) heated by steam. The crumb is then separated from the hot water. Then, necessary dehydration and drying are performed on the extracted crumb. Then, if the crumb is press-molded, a block-shaped rubber material (intermediate product) is obtained.
 そして、上記ゴム製品の製造過程において、クラムを熱湯から分離し取り出すために、従来、固定式スクリーン又は循環駆動型スクリーンが、使用されている。 In the manufacturing process of the rubber product, a fixed screen or a circulation drive type screen is conventionally used to separate and remove the crumb from hot water.
 固定式スクリーンとは、例えば、水平面に対して傾斜させて固定された、金網製の平面スクリーンである。その平面スクリーン上に、分散されたクラムを含む熱湯を送り込むと、熱湯が、平面スクリーンの網目を通過する。一方、平面スクリーン上に残されるクラムは、傾斜させたその平面スクリーンから、落下する。このようにして、クラムを、熱湯から分離することが出来る。 The fixed screen is, for example, a flat screen made of wire mesh that is fixed while being inclined with respect to a horizontal plane. When hot water containing dispersed crumbs is fed onto the flat screen, the hot water passes through the mesh of the flat screen. On the other hand, the crumbs left on the flat screen fall from the inclined flat screen. In this way, the crumb can be separated from the hot water.
 循環駆動型スクリーンとは、多数の金属製プレートを組み合わせて形成した、無端軌道状スクリーンである(特許文献1を参照)。その無端軌道状スクリーン上に、分散されたクラムを含む熱湯を送り込むと、熱湯は、金属製プレートが形成するスリットの隙間を通過する。一方、循環駆動型スクリーン上に残されるクラムは、所定方向に搬送され、循環駆動型スクリーンから離れる。このようにして、クラムを熱湯から分離可能である。 The circulation drive screen is an endless track screen formed by combining a number of metal plates (see Patent Document 1). When hot water containing dispersed crumbs is fed onto the endless track-like screen, the hot water passes through a gap between slits formed by a metal plate. On the other hand, the crumbs left on the circulation drive type screen are conveyed in a predetermined direction and leave the circulation drive type screen. In this way, the crumb can be separated from the hot water.
特開平6-304417号公報JP-A-6-304417
 しかしながら、これら固定式スクリーン又は循環駆動型スクリーンを用いて、クラムを熱湯から分離しようとすると、以下のような改善すべき問題に、直面する。 However, when the crumb is separated from the hot water using the fixed screen or the circulation drive type screen, the following problems to be improved are encountered.
 先ず、固定式スクリーンでは、平面スクリーンの網目に、小径のクラムが入り込み残存して、網目を閉塞させることがある。そうなると、熱湯の分離効果が低下し、後の脱水・乾燥工程に、クラムとともに、多量の遊離水が供給されてしまう。そうなると、その脱水や乾燥によっても、クラムから水分が除けない。そして、中間製品であるブロック状ゴム素材に、過多の水分が含まれるおそれが生じる。 First, in a fixed screen, a small-diameter crumb may enter and remain in the mesh of the flat screen, thereby closing the mesh. If it becomes so, the isolation | separation effect of hot water will fall, and a lot of free water will be supplied with a crumb in the subsequent dehydration and drying process. If that happens, water cannot be removed from the crumbs even by dehydration and drying. And there exists a possibility that excessive water | moisture content may be contained in the block-shaped rubber raw material which is an intermediate product.
 又、網目に残存したクラムに、新たなクラムが付着して、大きな塊に成長する場合がある。そして、その大きな塊のクラムが、突然、網目から剥離して、後の脱水・乾燥工程に送られる場合がある。この場合には、その脱水・乾燥工程において搬送不良が生じ、工程(生産過程)を停止させてしまう懸念がある。又、脱水・乾燥不良が生じ易いので、最終的に、中間製品であるブロック状ゴム素材に、過多の水分が含まれるおそれがある。 Also, new crumbs may adhere to the crumbs remaining on the mesh and grow into large lumps. Then, the large lumps of crumb may suddenly peel off from the mesh and be sent to the subsequent dehydration / drying process. In this case, there is a concern that conveyance failure occurs in the dehydration / drying process, and the process (production process) is stopped. In addition, since dehydration and drying defects are likely to occur, there is a possibility that excessive water is finally contained in the block-shaped rubber material that is an intermediate product.
 上記のような問題は、ゴム製品の仕様により、製造過程における重合体の付着性、凝集性が高い場合や、クラムをより小さい径にする場合に、起こり易くなる。これらの問題を解消するために、例えば、スクリーンを10~15日毎に交換する等の対策が考えられる。しかしながら、この定期的な作業は、非常に手間がかかる。加えて、これらの作業の間は工程(生産過程)が停止となるため、中間製品の生産効率を低下させる。又、このスクリーンの交換頻度を少なくするためには、15~30分毎に高圧洗浄を実施するといった対策も考えられる。しかしながら、この定期作業も、非常に手間がかかる。 The above problems are likely to occur when the adhesion and cohesiveness of the polymer in the production process are high or when the crumb has a smaller diameter depending on the specifications of the rubber product. In order to solve these problems, for example, measures such as changing the screen every 10 to 15 days can be considered. However, this regular work is very time-consuming. In addition, since the process (production process) is stopped during these operations, the production efficiency of the intermediate product is lowered. In order to reduce the frequency of replacement of the screen, a measure such as performing high pressure cleaning every 15 to 30 minutes can be considered. However, this regular work is also very time-consuming.
 循環駆動型スクリーンでは、以下のような、別の問題も抱えている。先ず、スリットを形成する金属製プレートは、駆動時に互いの摺動するため、メタルタッチ(金属どうしの接触)が多い。そのため、浮遊した金属が、クラムに、ひいては中間製品であるブロック状ゴム素材に、意図せず、混入するおそれが生じる。 The circulation drive type screen has other problems as follows. First, since the metal plates forming the slit slide with each other when driven, there are many metal touches (contact between metals). For this reason, the floating metal may unintentionally be mixed into the crumb and eventually into the block-shaped rubber material that is an intermediate product.
 又、循環駆動型スクリーンは、その使用によって、無端軌道状スクリーンを構成する多数の金属製プレートが伸張し、各金属製プレートが不平行になる。そのため、定期的に、張力や位置の調整が、必要になる。更に、無端軌道状スクリーンを駆動する部品であるチェーンは、長期間の連続使用によって、ブッシュ等の構成部品が、劣化することがある。そして、劣化の状態によっては、チェーン全体又はブッシュ等の構成部品の交換を、必要とする。これら調整や交換の作業には、作業者の熟練と多大な時間・手間を要するとともに、長時間の試運転が必要となる。加えて、これらの作業・試運転の間は、工程(生産過程)が停止となるため、中間製品の生産効率を低下させる。そして、チェーンにおいても、メタルタッチが起こる。そのため、浮遊した金属が、クラムに、ひいては中間製品であるブロック状ゴム素材に、意図せず、混入するおそれが生じる。 In addition, the use of the circulation drive type screen causes a large number of metal plates constituting the endless track-shaped screen to extend, and the metal plates become non-parallel. Therefore, it is necessary to adjust the tension and position periodically. Furthermore, in a chain that is a component that drives an endless track-like screen, components such as a bush may deteriorate due to long-term continuous use. Depending on the state of deterioration, it is necessary to replace the entire chain or components such as bushes. These adjustment and replacement operations require skill of the worker and a great deal of time and effort, and also require a long test run. In addition, since the process (production process) is stopped during these operations and test runs, the production efficiency of intermediate products is reduced. Metal touch also occurs in the chain. For this reason, the floating metal may unintentionally be mixed into the crumb and eventually into the block-shaped rubber material that is an intermediate product.
 本発明は、このような事情に鑑みてなされたものであり、その課題とするところは、クラムと熱湯とを良好に分離することが出来、ひいては液中に分散した固体状重合体をその液から分離することが可能な手段を、提供することである。又、クラム(固体状重合体)に金属が混入するおそれがなく、且つ、クラム(固体状重合体)に多くの水分(熱湯、液)が残存せず、従って、中間製品であるブロック状ゴム素材に金属や過多の水分が含まれることもない手段を、提供することである。加えて、洗浄、調整、交換等の作業が不要ないし頻度が少なくて済み、長期の間、連続して製造過程を止める必要がない手段を、提供することである。研究が重ねられた結果、以下の手段によって、この課題が解決されることが見出され、本発明の完成に至った。 The present invention has been made in view of such circumstances, and the problem is that crumb and hot water can be satisfactorily separated, and as a result, a solid polymer dispersed in the liquid can be separated from the liquid. To provide a means that can be separated from In addition, there is no risk of metal mixing into the crumb (solid polymer), and much water (hot water, liquid) does not remain in the crumb (solid polymer), so the block rubber is an intermediate product. It is to provide a means in which the material does not contain metal or excessive moisture. In addition, it is necessary to provide a means that does not require or requires less work such as cleaning, adjustment, and replacement, and does not need to stop the manufacturing process continuously for a long time. As a result of repeated research, it has been found that this problem can be solved by the following means, and the present invention has been completed.
 即ち、先ず、本発明によれば、液中に分散した固体状重合体を、その液から分離する装置であって、多数のスリットが形成された筒状のスクリーン、そのスクリーンを(周方向に)回転させる駆動機構、スクリーンの内周面に設けられる案内板、スクリーンの外周面側において、そのスクリーンの外周面に向けて設けられる第1の液体噴射機構、及び、少なくともスクリーンを囲うとともに、下方に排出口を有するケーシング、を具備する固体状重合体用分離装置が提供される。 That is, first, according to the present invention, an apparatus for separating a solid polymer dispersed in a liquid from the liquid, a cylindrical screen having a large number of slits, and the screen (in the circumferential direction). ) A driving mechanism to be rotated, a guide plate provided on the inner peripheral surface of the screen, a first liquid ejecting mechanism provided toward the outer peripheral surface of the screen on the outer peripheral surface side of the screen, and at least surrounding the screen and below There is provided a solid polymer separation device comprising a casing having a discharge port.
 筒状のスクリーンにおいて、例えば、ワイヤーを平行に並べて、周面にあたる部分を構成すれば、多数のスリットを形成することが出来る。スリット(ワイヤーの間隙)は、処理対象である固体状重合体の大きさによって、任意に設定することが出来る。スクリーンの洗浄性を考慮すると、スリットは、1~3mmであることが好ましく、1.5~2.5mmであることが特に好ましい。スクリーンの形状は、円筒状であることが、特に好ましい。この場合、駆動機構は、スクリーンを、円周方向に回転させる。 In a cylindrical screen, for example, if wires are arranged in parallel to form a portion corresponding to the peripheral surface, a large number of slits can be formed. The slit (gap between the wires) can be arbitrarily set depending on the size of the solid polymer to be processed. In consideration of the cleanability of the screen, the slit is preferably 1 to 3 mm, particularly preferably 1.5 to 2.5 mm. The shape of the screen is particularly preferably a cylindrical shape. In this case, the drive mechanism rotates the screen in the circumferential direction.

The drive tube and the screen are placed on the roller, so that the drive tube and the screen rotate smoothly.
 案内板は、スクリーンの内周面において、筒状のスクリーンの入口側から出口側まで設けられる。この案内板は、螺旋状であることが、好ましい。この螺旋状の案内板は、処理対象である固体状重合体の仕切板であり、溝を形成する。後述する延長管を設ける場合に、その延長管に案内板を設けることが好ましい。案内板は、連続して又は断続して形成されるが、好ましくは連続して形成される。案内板が螺旋状である場合に、その条数は、処理対象である固体状重合体の処理量(時間あたりの質量)や、後の脱水・乾燥工程へのクラムの供給状況によって、任意に設定することが出来る。スクリーンの洗浄性を考慮すると、螺旋状の案内板の条数は、4~8であることが好ましく、5~7であることが特に好ましい。螺旋状の案内板の高さは、処理対象である固体状重合体の処理量(時間あたりの質量)によって、任意に設定することが出来る。スクリーンの洗浄性を考慮すると、螺旋状の案内板の高さは、5~15cmであることが好ましく、8~12cmであることが特に好ましい。 The guide plate is provided on the inner peripheral surface of the screen from the entrance side to the exit side of the cylindrical screen. The guide plate is preferably spiral. The spiral guide plate is a partition plate made of a solid polymer to be processed, and forms a groove. When providing an extension pipe to be described later, it is preferable to provide a guide plate on the extension pipe. The guide plate is formed continuously or intermittently, but is preferably formed continuously. When the guide plate is spiral, the number of strips is arbitrarily determined depending on the processing amount (mass per hour) of the solid polymer to be processed and the supply status of crumb to the subsequent dehydration / drying process. It can be set. In consideration of the cleanability of the screen, the number of spiral guide plates is preferably 4 to 8, and more preferably 5 to 7. The height of the spiral guide plate can be arbitrarily set according to the processing amount (mass per hour) of the solid polymer to be processed. Considering the cleanability of the screen, the height of the spiral guide plate is preferably 5 to 15 cm, particularly preferably 8 to 12 cm.
 本明細書において、入口側とは、処理対象である液及びその中に分散した固体状重合体が入る(投入される)側である。出口側とは、処理された(液から分離された)固体状重合体が出る(排出される)側である。本明細書において、入口側、出口側という語は、筒状のスクリーンに対してだけではなく、固体状重合体用分離装置全体や、スクリーン以外の要素に対しても、使用される。 In this specification, the inlet side is the side into which the liquid to be treated and the solid polymer dispersed therein are introduced (injected). The outlet side is the side from which the treated (separated from the liquid) solid polymer exits (is discharged).

 第5の液体噴射機構は、例えば、噴射先が延長管の内周面下側になるように、且つ、筒状のスクリーンの出口近傍(即ち、延長管の近傍)であって軸方向に垂直な面(円形)の中心に噴射口が位置するように、支持具又は配管によって、取り付けられる。第5の液体噴射機構から、液体を延長管の内周面下側へ噴射して、固体状重合体の付着を、防止することが出来る。併せて、液体として冷水を使用することによって、次工程(脱水・乾燥等)へ向かう固体状重合体を、冷やすことが出来る。第5の液体噴射機構の数は、延長管の内周面の大きさ(面積)に対して、任意に設定することが出来る。延長管の洗浄性を考慮すると、1~5個設けることが好ましく、2~4個設けることが特に好ましい。 The fifth liquid ejecting mechanism is, for example, in the vicinity of the outlet of the cylindrical screen (ie, near the extension tube) and perpendicular to the axial direction so that the spray destination is below the inner peripheral surface of the extension tube. It is attached by a support tool or piping so that the injection port is located at the center of the flat surface (circular). The liquid can be ejected from the fifth liquid ejecting mechanism to the lower side of the inner peripheral surface of the extension tube to prevent the solid polymer from adhering. In addition, by using cold water as the liquid, the solid polymer going to the next step (dehydration, drying, etc.) can be cooled. The number of the fifth liquid ejecting mechanisms can be arbitrarily set with respect to the size (area) of the inner peripheral surface of the extension pipe. In consideration of the detergency of the extension tube, it is preferable to provide 1 to 5, and particularly preferably 2 to 4.
 第1の液体噴射機構、第3の液体噴射機構、及び第4の液体噴射機構において、使用する(噴射する)液体の圧力は、それぞれの洗浄性を考慮すると、高いほど好ましい。噴射先(スクリーン等)の強度や、スクリーンの回転に対する抵抗を考慮すると、液体の圧力は、1~7MPaであることが好ましい。 In the first liquid ejecting mechanism, the third liquid ejecting mechanism, and the fourth liquid ejecting mechanism, the pressure of the liquid to be used (injected) is preferably as high as possible in consideration of the respective cleaning properties. Considering the strength of the spray destination (screen or the like) and the resistance against rotation of the screen, the pressure of the liquid is preferably 1 to 7 MPa.
 一方、第2の液体噴射機構において、使用する(噴射する)液体の圧力は、スクリーン内部でのクラムの飛散等を考慮すると、第1の液体噴射機構、第3の液体噴射機構、及び第4の液体噴射機構と同じ程、高い圧力は必要ない。液体の圧力は、0.2~0.6MPa程度であることが好ましい。 On the other hand, in the second liquid ejecting mechanism, the pressure of the liquid to be used (injected) is determined based on the first liquid ejecting mechanism, the third liquid ejecting mechanism, and the fourth liquid in consideration of scattering of crumbs inside the screen. High pressure is not required as in the case of the liquid jet mechanism. The pressure of the liquid is preferably about 0.2 to 0.6 MPa.
 第1の液体噴射機構、第2の液体噴射機構、第3の液体噴射機構、及び第4の液体噴射機構において、使用する(噴射する)液体の温度は、処理対象である固体状重合体の硬度、粘度、付着性、凝集性に代表される物性の温度依存性によって、任意に設定することが出来る。付着性(あるいは剥がし易さ)を考慮すると、液体の温度は、50~95℃であることが好ましく、70~90℃であることが特に好ましい。 In the first liquid ejecting mechanism, the second liquid ejecting mechanism, the third liquid ejecting mechanism, and the fourth liquid ejecting mechanism, the temperature of the liquid to be used (injected) is that of the solid polymer to be processed. It can be arbitrarily set depending on the temperature dependence of physical properties represented by hardness, viscosity, adhesion, and cohesion. In consideration of adhesion (or ease of peeling), the temperature of the liquid is preferably 50 to 95 ° C, and particularly preferably 70 to 90 ° C.
 一方、第5の液体噴射機構において、使用する(噴射する)液体の圧力は、0.1~0.6MPaであればよい。又、第5の液体噴射機構において、使用する(噴射する)液体の温度は、5~40℃であることが好ましく、15~30℃であることが特に好ましい。 On the other hand, in the fifth liquid ejecting mechanism, the pressure of the liquid used (injected) may be 0.1 to 0.6 MPa. In the fifth liquid ejecting mechanism, the temperature of the liquid to be used (injected) is preferably 5 to 40 ° C., and particularly preferably 15 to 30 ° C.
 第1の液体噴射機構、第2の液体噴射機構、第3の液体噴射機構、第4の液体噴射機構、及び第5の液体噴射機構は、それぞれ、例えば、圧力を有する液体源に配管を介して接続される噴射ノズルで、構成される。圧力を有する液体源とは、例えば、液体を貯めるタンクと液体を送り出すポンプであり、これらは、本発明に係る固体状重合体用分離装置の構成に、含まれなくてもよい。 For example, the first liquid ejecting mechanism, the second liquid ejecting mechanism, the third liquid ejecting mechanism, the fourth liquid ejecting mechanism, and the fifth liquid ejecting mechanism are respectively connected to a liquid source having pressure via a pipe. It is composed of spray nozzles connected together. The liquid source having pressure is, for example, a tank for storing liquid and a pump for sending out liquid, and these may not be included in the configuration of the solid polymer separation device according to the present invention.
 本発明に係る固体状重合体用分離装置においては、駆動機構が、スクリーンの回転速度を調節可能であることが好ましい。 In the solid polymer separation device according to the present invention, it is preferable that the drive mechanism can adjust the rotation speed of the screen.
 例えば、駆動機構の駆動源の回転数を任意に調節することによって、スクリーンの回転数を任意に制御可能である。具体的には、駆動機構の駆動源が電動機である場合には、インバータを設けて周波数制御等によって、スクリーンの回転速度を調節することが出来る。スクリーンの回転数は、筒状のスクリーンの大きさ(円筒状のスクリーンであれば、その径)や、処理対象である固体状重合体の処理量(時間あたりの質量)及び固体状重合体分離装置の出口におけるクラム中の水分量によって、任意に設定することが出来る。好ましいスクリーンの回転数は、5~35rpmであり、12~28rpmであればより好ましい。 For example, the rotation speed of the screen can be arbitrarily controlled by arbitrarily adjusting the rotation speed of the drive source of the drive mechanism. Specifically, when the drive source of the drive mechanism is an electric motor, the rotation speed of the screen can be adjusted by providing an inverter and performing frequency control or the like. The number of rotations of the screen is the size of the cylindrical screen (the diameter of a cylindrical screen), the processing amount of the solid polymer to be processed (mass per hour), and the solid polymer separation. It can be set arbitrarily depending on the amount of water in the crumb at the outlet of the apparatus. The rotation speed of the screen is preferably 5 to 35 rpm, more preferably 12 to 28 rpm.
 本発明に係る固体状重合体用分離装置においては、スクリーンとケーシングとの間に、水切板を具備することが好ましい。この水切板は、スクリーンの系外(外側)から系内(内側)への、異物の侵入を防止するものである。より具体的には、ケーシングの駆動部(入口側のローラーがある空間)と分離された熱湯が流れる部分との間に、外側(ローラーのある空間)から内側(分離された熱湯が流れる空間)への異物の侵入を防止する、水切板を具備することが好ましい。又、分離された熱湯が流れる部分と出口側のローラーがある空間との間に、外側(ローラーのある空間)から内側(分離された熱湯が流れる空間)への異物の侵入を防止する、水切板を具備することが好ましい。異物とは、例えば、ローラーの削れ片である。ローラーは、駆動力伝達機構を構成する部品である。 In the solid polymer separation device according to the present invention, it is preferable to provide a draining plate between the screen and the casing. This draining plate prevents intrusion of foreign matter from outside (outside) the system to inside (inside) the screen. More specifically, between the drive part of the casing (space where the roller on the inlet side is located) and the portion where the separated hot water flows, from the outside (space where the roller is located) to the inside (space where the separated hot water flows) It is preferable to provide a draining plate that prevents foreign matter from entering the body. In addition, a drainer that prevents foreign matter from entering from the outside (the space where the roller is located) to the inside (the space where the separated hot water flows) between the portion where the separated hot water flows and the space where the roller on the outlet side is located. It is preferable to comprise a board. The foreign material is, for example, a scraped piece of a roller. The roller is a component that constitutes a driving force transmission mechanism.
 本発明に係る固体状重合体用分離装置は、固体状重合体が、ブタジエンゴム、イソプレンゴム、スチレン・ブタジエンゴム、スチレン・イソプレンゴム、エチレン・α-オレフィン共重合ゴム、エチレン・α-オレフィン・非共役ジエン共重合ゴム、ブチルゴム、スチレン・ブタジエン・スチレンブロック共重合体、水素添加スチレン・ブタジエン・スチレンブロック共重合体、ブタジエン樹脂、及びアクリル樹脂からなる重合体群から選ばれる重合体である場合に、好適に使用される。 In the separation apparatus for a solid polymer according to the present invention, the solid polymer is butadiene rubber, isoprene rubber, styrene / butadiene rubber, styrene / isoprene rubber, ethylene / α-olefin copolymer rubber, ethylene / α-olefin / When the polymer is selected from the group consisting of non-conjugated diene copolymer rubber, butyl rubber, styrene / butadiene / styrene block copolymer, hydrogenated styrene / butadiene / styrene block copolymer, butadiene resin, and acrylic resin.

 次に、本発明によれば、上記した何れかの固体状重合体用分離装置を用いて、液中に分散した固体状重合体を、その液から分離する固体状重合体の分離方法が提供される。 Next, according to the present invention, there is provided a solid polymer separation method for separating a solid polymer dispersed in a liquid from the liquid using any of the above-described solid polymer separation devices. Is done.
 次に、本発明によれば、溶媒と混合されたモノマーを重合して、重合体を得る重合工程、蒸気を作用させて、重合体から溶媒を除去する溶媒除去工程、上記した何れかの固体状重合体用分離装置を用いて、溶媒が除去された重合体を、蒸気が液化した熱湯から分離する分離工程、熱湯から分離された重合体の水分を、更に除去する脱水工程及び乾燥工程、及び、水分が除去された重合体を、所定の形状に成形する成形工程、を有するゴム素材の製造方法が提供される。 Next, according to the present invention, a polymerization step for polymerizing a monomer mixed with a solvent to obtain a polymer, a solvent removal step for removing the solvent from the polymer by applying steam, and any of the solids described above A separation process for separating the polymer from which the solvent has been removed from the hot water in which the vapor has been liquefied, a dehydration process and a drying process for further removing the water of the polymer separated from the hot water, using a polymer separator. And the manufacturing method of the rubber raw material which has a shaping | molding process which shape | molds the polymer from which the water | moisture content was removed into a defined shape is provided.
 本発明に係る固体状重合体用分離装置は、多数のスリットが形成された筒状のスクリーン、そのスクリーンを回転させる駆動機構、及びスクリーンの内周面に設けられる案内板を有する。そのため、筒状のスクリーンの一方の開口(入口)から、液中に分散した固体状重合体を連続的に投入すれば、液(例えば熱湯)は、スリットを通過して、ケーシング下方の排出口から系外へ排出される。一方、固体状重合体(例えばクラム)は、その液とは分離されて、筒状のスクリーンの内周面に残り、案内板の案内に従って、定量ずつ、筒状のスクリーンの他方の開口(出口)から、排出される。そして、第1の液体噴射機構及び第2の液体噴射機構が、スクリーンの外周面及び内周面において、固体状重合体の付着・凝集を防止する。又は、第1の液体噴射機構及び第2の液体噴射機構が、付着した固体状重合体をスクリーンから取り除く。そのため、スクリーンのスリットが閉塞しない。従って、いわば有効濾過面積が減少することはなく、液(例えば熱湯)の分離効果は低下しない。よって、液中に分散した固体状重合体を、その液から、良好に分離することが可能である。処理後の固体状重合体(例えばクラム)に、多くの水分(液(例えば熱湯))が残存することはない。最終的な製品(例えば中間製品であるブロック状ゴム素材)に、過多の水分が含まれることもない。 The solid polymer separation device according to the present invention includes a cylindrical screen having a large number of slits, a drive mechanism for rotating the screen, and a guide plate provided on the inner peripheral surface of the screen. Therefore, if a solid polymer dispersed in the liquid is continuously introduced from one opening (inlet) of the cylindrical screen, the liquid (for example, hot water) passes through the slit and is discharged from the lower part of the casing. Is discharged from the system. On the other hand, the solid polymer (for example, crumb) is separated from the liquid and remains on the inner peripheral surface of the cylindrical screen. ) Is discharged. The first liquid ejecting mechanism and the second liquid ejecting mechanism prevent adhesion and aggregation of the solid polymer on the outer peripheral surface and the inner peripheral surface of the screen. Alternatively, the first liquid ejecting mechanism and the second liquid ejecting mechanism remove the attached solid polymer from the screen. For this reason, the slit of the screen does not close. Therefore, the effective filtration area does not decrease, and the separation effect of the liquid (for example, hot water) does not decrease. Therefore, it is possible to satisfactorily separate the solid polymer dispersed in the liquid from the liquid. Much moisture (liquid (for example, hot water)) does not remain in the solid polymer (for example, crumb) after the treatment. The final product (for example, a block-shaped rubber material that is an intermediate product) does not contain excessive moisture.
 本発明に係る固体状重合体用分離装置は、固体状重合体が投入されるスクリーンは、回転するだけである。そして、その回転の間、固体状重合体は、案内板の案内に従って、入口から出口に向けて、移動するだけである。分離の処理の間、固体状重合体用分離装置(スクリーン)の中で、クラムや液体が、直接、接触する部分では、メタルタッチが起こらない。もっとも、例えば、スクリーンの駆動機構を、電動機に接続されたスプロケットと、駆動管の周上に撒きつけられたチェーンと、が噛み合っている構造とした場合には、メタルタッチが起こり得る。しかしながら、その駆動機構のある空間と、分離されたクラム及び液体のある空間とは、それぞれ水切り板等によって、遮られている。よって、この場合であっても、処理後の固体状重合体(例えばクラム)に金属が混入することはない。従って、最終的な製品(例えば中間製品であるブロック状ゴム素材)に、金属が含まれることもない。 In the solid polymer separation device according to the present invention, the screen into which the solid polymer is charged only rotates. During the rotation, the solid polymer only moves from the inlet toward the outlet according to the guide of the guide plate. During the separation process, metal touch does not occur in the solid polymer separation device (screen) where the crumb or liquid directly contacts. However, for example, when the screen drive mechanism has a structure in which a sprocket connected to the electric motor and a chain wound around the circumference of the drive pipe are engaged with each other, a metal touch can occur. However, the space where the driving mechanism is located and the space where the separated crumb and liquid are located are blocked by a draining plate or the like. Therefore, even in this case, the metal is not mixed into the solid polymer (for example, crumb) after the treatment. Accordingly, the final product (for example, a block-shaped rubber material that is an intermediate product) does not contain metal.
 本発明に係る固体状重合体用分離装置には、チェーン等の調整・交換を要する部品が存在しない。そのため、それらの調整、交換等の作業が不要である。従って、長期の間、連続して製造過程を止める必要がなく、製品(例えば中間製品であるブロック状ゴム素材)の生産効率向上に寄与する。 In the solid polymer separation device according to the present invention, there are no parts such as a chain that require adjustment and replacement. Therefore, work such as adjustment and replacement is unnecessary. Therefore, it is not necessary to stop the production process continuously for a long time, which contributes to an improvement in production efficiency of a product (for example, a block-shaped rubber material that is an intermediate product).
 本発明に係る固体状重合体用分離装置は、上記の通り、第1の液体噴射機構及び第2の液体噴射機構が、スクリーンの外周面及び内周面において、固体状重合体の付着・凝集を防止する。加えて、本発明に係る固体状重合体用分離装置は、好ましくは、第3の液体噴射機構及び第4の液体噴射機構を具備する。そして、それら第3の液体噴射機構及び第4の液体噴射機構が、ケーシングの内面(天井面、側面、及び底面)において、固体状重合体の付着を防止する。そして、これら全ての液体噴射機は、分離処理の間、連続して、液体を噴射させることが出来る。又、上記の通り、スクリーンへの固体状重合体の付着・凝集が防止されれば、洗浄、調整等の作業は不要ないし頻度が少なくて済む。従って、長期の間、連続して製造過程を止める必要がなく、製品(例えば中間製品であるブロック状ゴム素材)の生産効率向上に寄与する。 In the solid polymer separation device according to the present invention, as described above, the first liquid ejecting mechanism and the second liquid ejecting mechanism are attached and aggregated on the outer peripheral surface and inner peripheral surface of the screen. To prevent. In addition, the solid polymer separation device according to the present invention preferably includes a third liquid ejecting mechanism and a fourth liquid ejecting mechanism. The third liquid ejecting mechanism and the fourth liquid ejecting mechanism prevent the solid polymer from adhering to the inner surface (the ceiling surface, the side surface, and the bottom surface) of the casing. All these liquid ejectors can continuously eject liquid during the separation process. As described above, if the solid polymer is prevented from adhering to and agglomerated on the screen, operations such as washing and adjustment are unnecessary and less frequent. Therefore, it is not necessary to stop the production process continuously for a long time, which contributes to an improvement in production efficiency of a product (for example, a block-shaped rubber material that is an intermediate product).
 本発明に係る固体状重合体用分離装置は、好ましくは筒状のスクリーンの出口側において、その延長管の内周面下側に向けて設けられる第5の液体噴射機構を具備する。そのため、固体状重合体に、直接、液体(例えば冷水)を噴霧することが出来、それによって、次の脱水・乾燥工程に供給するクラムの温度を、調節することが可能である。 The separation device for a solid polymer according to the present invention preferably includes a fifth liquid ejecting mechanism provided on the outlet side of the cylindrical screen toward the lower side of the inner peripheral surface of the extension tube. Therefore, a liquid (for example, cold water) can be directly sprayed on the solid polymer, and thereby the temperature of the crumb supplied to the next dehydration / drying process can be adjusted.
 本発明に係る固体状重合体用分離装置では、液から分離され、案内板の案内に従って運ばれた固体状重合体は、そのまま、次工程へ向かう。加えて、一旦は、スクリーンやケーシングの内面(天井面、側面、及び底面)に付着し、第1の液体噴射機構~第4の液体噴射機構によって取り除かれた固体状重合体は、落下して、液体とともに、ケーシング下方の排出口から、排出される。この排出された液体及び固体状重合体は、静置分離を施した後で回収され、あらためて本発明に係る固体状重合体用分離装置へ投入される。そして、再び、本発明に係る固体状重合体用分離装置において、固体状重合体を液体から分離することが出来る。こうすると、系外に出される固体状重合体はなくなり、概ね100%回収することが出来、製品(例えば中間製品であるブロック状ゴム素材)の生産効率向上に寄与する。又、もともと固体状重合体を分散していた液も、第1の液体噴射機構~第4の液体噴射機構から噴射する液体として、再利用することが可能である。このように、本発明に係る固体状重合体用分離装置は、無駄な廃棄物を出さない、環境負荷の小さい、優れた装置ということが出来る。 In the separation apparatus for solid polymer according to the present invention, the solid polymer separated from the liquid and carried according to the guide of the guide plate goes to the next process as it is. In addition, the solid polymer that has once adhered to the inner surfaces (the ceiling surface, the side surface, and the bottom surface) of the screen or casing and has been removed by the first liquid ejecting mechanism to the fourth liquid ejecting mechanism has dropped. The liquid is discharged from the discharge port below the casing together with the liquid. The discharged liquid and solid polymer are recovered after static separation, and are again supplied to the solid polymer separation apparatus according to the present invention. Again, in the solid polymer separation device according to the present invention, the solid polymer can be separated from the liquid. In this way, there is no solid polymer discharged out of the system, and almost 100% of the polymer can be recovered, contributing to an improvement in production efficiency of a product (for example, a block-shaped rubber material that is an intermediate product). Also, the liquid in which the solid polymer is originally dispersed can be reused as the liquid ejected from the first liquid ejecting mechanism to the fourth liquid ejecting mechanism. Thus, the separation apparatus for solid polymer according to the present invention can be said to be an excellent apparatus that does not generate waste and has a small environmental load.

 スクリーン11は、円筒状を呈し、その周面は、(好ましくは)断面が三角形状のワイヤー111を、円筒状のスクリーン11の軸方向に規則正しく平行に並べて固定して、形成される(図2A~図2Cを参照)。そして、ワイヤー111によって、熱湯を通過させるための多数のスリット112が形成される。このスリット112の幅(目開き)は、(好ましくは)1.5~2.5mmである。 The screen 11 has a cylindrical shape, and its peripheral surface is formed by fixing (preferably) a wire 111 having a triangular cross-section regularly and parallel to the axial direction of the cylindrical screen 11 (FIG. 2A). See FIG. 2C). And many slits 112 for allowing hot water to pass through are formed by the wire 111. The width (opening) of the slit 112 is (preferably) 1.5 to 2.5 mm.
 駆動機構12は、スクリーン11を円周方向S(図2B及び図2Cを参照)に回転させる手段である。駆動機構12は、電動機121と、電動機に接続されたスプロケット141と、スクリーン11の入口側(図1A及び図2Aにおいて左側)に接続するように設けた駆動管123と、駆動管円周上に巻きつけられたチェーン142及び、その駆動管123に密着させて設けた4つのローラー122と、で構成される(図4を参照)。電動機121に接続されたスプロケット141とチェーン142が噛み合っており、電動機121を廻して、それに固定されたスプロケット141を回転させれば、スプロケット141に噛み合っているチェーン142及び駆動管12が回転し、それに接続されるスクリーン11が、回転する。4つのローラー122は、滑らかに回転させるように、駆動管123と、スクリーン11、及び延長管13を支持する。電動機121の回路には(例えば)インバータが設けられており、電動機121の回転数を調節し、変更することが可能である。これは、スクリーン11の回転数を(好ましくは)12~28rpmに調節可能なことを意味する。 The drive mechanism 12 is means for rotating the screen 11 in the circumferential direction S (see FIGS. 2B and 2C). The drive mechanism 12 includes an electric motor 121, a sprocket 141 connected to the electric motor, a drive pipe 123 provided so as to be connected to the inlet side of the screen 11 (left side in FIGS. 1A and 2A), and a drive pipe circumference. The chain 142 is wound around and four rollers 122 provided in close contact with the drive tube 123 (see FIG. 4). The sprocket 141 connected to the electric motor 121 and the chain 142 are engaged with each other. When the electric motor 121 is rotated and the sprocket 141 fixed thereto is rotated, the chain 142 and the drive pipe 12 engaged with the sprocket 141 are rotated. The screen 11 connected to it rotates. The four rollers 122 support the drive tube 123, the screen 11, and the extension tube 13 so as to rotate smoothly. The circuit of the electric motor 121 is provided with an inverter (for example), and the number of rotations of the electric motor 121 can be adjusted and changed. This means that the number of rotations of the screen 11 can be adjusted to (preferably) 12 to 28 rpm.
 延長管13は、円筒状のスクリーン11の出口側に接続される。この延長管13は、スクリーン11と同径の円筒状を呈するが、ワイヤーで形成されるスクリーンではなく、円筒状の金属板である。 The extension tube 13 is connected to the outlet side of the cylindrical screen 11. The extension tube 13 has a cylindrical shape having the same diameter as the screen 11, but is not a screen formed of a wire but a cylindrical metal plate.
 螺旋状の案内板15は、スクリーン11及びそれに接続される延長管13の内周面において、スクリーン11の入口側から出口側、更には延長管13まで、(例えば)連続して設けられている(図2A~図2Cを参照)。この螺旋状の案内板15によって、スクリーン11及び延長管13の内周面に溝151が形成される。この螺旋状の案内板15の条数は(好ましくは)4~8であり、高さHは(好ましくは)5~15cmであり、スクリーンに対して垂直に設置されていることが好ましい(図2B及び図2Cを参照)。 The spiral guide plate 15 is provided continuously (for example) from the inlet side to the outlet side of the screen 11 and further to the extension pipe 13 on the inner peripheral surface of the screen 11 and the extension pipe 13 connected thereto. (See FIGS. 2A-2C). The spiral guide plate 15 forms a groove 151 on the inner peripheral surfaces of the screen 11 and the extension tube 13. The spiral guide plate 15 has (preferably) 4 to 8 strips, preferably has a height H of 5 to 15 cm (preferably), and is preferably installed perpendicular to the screen (see FIG. 2B and FIG. 2C).
 ケーシング18は、スクリーン11、駆動機構12、延長管13、案内板15、液体噴射機構16、液体噴射機構17、液体噴射機構21、液体噴射機構22、及び液体噴射機構23を、全て囲うとともに、上方に点検口181、下方に排出口182、をそれぞれ有する(図1A~図1Dを参照)。又、液体噴射機構21及び液体噴射機構22は、ケーシング18の内面に取り付けられる。ケーシング18の天井面は、断面が台形になるように形成されており、その斜面に点検口181が設けられている(図1C及び図1Dを参照)。又、ケーシング18の底面は傾斜し、テーパー状に狭まっており、その終端に排出口182が設けられる(図1Aを参照)。 The casing 18 surrounds the screen 11, the drive mechanism 12, the extension pipe 13, the guide plate 15, the liquid ejecting mechanism 16, the liquid ejecting mechanism 17, the liquid ejecting mechanism 21, the liquid ejecting mechanism 22, and the liquid ejecting mechanism 23, and An inspection port 181 is provided on the upper side and a discharge port 182 is provided on the lower side (see FIGS. 1A to 1D). The liquid ejecting mechanism 21 and the liquid ejecting mechanism 22 are attached to the inner surface of the casing 18. The ceiling surface of the casing 18 is formed to have a trapezoidal cross section, and an inspection port 181 is provided on the slope (see FIGS. 1C and 1D). Further, the bottom surface of the casing 18 is inclined and narrowed in a tapered shape, and a discharge port 182 is provided at the end thereof (see FIG. 1A).
 ケーシング18において、点検口181は、ケーシング18の内面(断面が台形になるように形成される天井面)が平坦になるように形成される(図6Aを参照)。そのため、後述する噴射ノズル213から噴射される液体の噴射流61によって、良好にクラムの付着・凝集を防止することが出来る。図6Bに示される従来の態様では、点検口62のみが凹むように設けられ、その結果、ケーシングの内面に凸凹が形成されてしまう。そうなると、液体の噴射流61では、ケーシング内面に液体が均等に噴射されず(行き渡らず)、付着したクラム63を取り除けないおそれがあるが、ケーシング18の点検口181によれば、このようなおそれはない。 In the casing 18, the inspection port 181 is formed so that the inner surface of the casing 18 (the ceiling surface formed so that the cross section becomes a trapezoid) is flat (see FIG. 6A). Therefore, crumbs can be prevented from adhering or agglomerating well by the liquid jet 61 jetted from the jet nozzle 213 described later. In the conventional mode shown in FIG. 6B, only the inspection port 62 is provided to be recessed, and as a result, unevenness is formed on the inner surface of the casing. In this case, in the liquid jet 61, the liquid is not evenly sprayed (spread) on the inner surface of the casing, and there is a risk that the attached crumb 63 may not be removed. Absent.
 又、ケーシング18の入口側(駆動管12が配設される位置)のローラー122がある空間と分離された熱湯が流れる部分との間、及び、ケーシング18の出口側(延長管13が配置される位置)の分離された熱湯が流れる部分と出口側のローラー122がある空間との間には、それぞれ外側(ローラー122のある空間)から内側(分離された熱湯が流れる空間)を遮るように水切り板131が設けられる(図3及び図4を参照)。この水切板131によって、外側から系内(ケーシング18の水が流れる部分)へ異物の侵入を、防止することが出来る。 Further, the space between the roller 122 on the inlet side of the casing 18 (position where the drive pipe 12 is disposed) and the portion where the separated hot water flows and the outlet side of the casing 18 (the extension pipe 13 is disposed). Between the portion where the separated hot water flows and the space where the outlet-side roller 122 is located so as to block the inner side (the space where the separated hot water flows) from the outside (the space where the roller 122 is located). A draining plate 131 is provided (see FIGS. 3 and 4). The draining plate 131 can prevent foreign matter from entering the system (portion where the water in the casing 18 flows) from the outside.
 液体噴射機構16は、(図示しない)液体源に接続される配管162と、それに設けられた噴射ノズル161で、構成される。配管162は、スクリーン11の(外周面の)斜め上方に2列で設けられ(図1B~図1Dを参照)、その1列毎に、(好ましくは)8~14個の噴射ノズル161が設けられる。噴射ノズル161の噴射先は、主にスクリーン11の外周面である。 The liquid ejecting mechanism 16 includes a pipe 162 connected to a liquid source (not shown) and an ejecting nozzle 161 provided thereon. The pipes 162 are provided in two rows obliquely above (outer peripheral surface) of the screen 11 (see FIGS. 1B to 1D), and (preferably) 8 to 14 injection nozzles 161 are provided for each row. It is done. The injection destination of the injection nozzle 161 is mainly the outer peripheral surface of the screen 11.
 液体噴射機構17は、(図示しない)液体源に接続される配管172と、その先端に設けられた噴射ノズル171で、構成される(図1A及び図1Dを参照)。配管172は、延長管13において(スクリーン11の出口近において)、上方から円筒状のスクリーン11(延長管13)の軸方向に垂直な面(円形)の中心に伸びるように配設される。そして、中心に(配管172の先端に)、(例えば)2つの噴射ノズル171が設けられる。2つの噴射ノズル171の噴射先は、何れもスクリーン11の内周面上側である。 The liquid ejection mechanism 17 includes a pipe 172 connected to a liquid source (not shown) and an ejection nozzle 171 provided at the tip thereof (see FIGS. 1A and 1D). The pipe 172 is disposed in the extension pipe 13 (near the exit of the screen 11) so as to extend from above to the center of a surface (circular) perpendicular to the axial direction of the cylindrical screen 11 (extension pipe 13). In the center (at the tip of the pipe 172), (for example) two injection nozzles 171 are provided. The injection destinations of the two injection nozzles 171 are both on the inner peripheral surface upper side of the screen 11.
 液体噴射機構21は、(図示しない)液体源に接続される配管212と、その先端に設けられた噴射ノズル211、及び噴射ノズル213で、構成される(図1A~図1Dを参照)。噴射ノズル211は、(例えば)四方を向くように4つ、ケーシング18の天井面の略中央に設けられる。噴射ノズル211の噴射先は、ケーシング18の4つの側面である。噴射ノズル213は、ケーシング18の天井面に、(例えば)2列に設けられる。この噴射ノズル213の噴射先は、クラムの付着が生じ易い、スクリーンと平行にある側面(2面)を重点的に洗浄するように、向けられる。 The liquid ejecting mechanism 21 includes a pipe 212 connected to a liquid source (not shown), an ejecting nozzle 211 provided at the tip thereof, and an ejecting nozzle 213 (see FIGS. 1A to 1D). Four injection nozzles 211 are provided at substantially the center of the ceiling surface of the casing 18 so as to face (for example) four directions. The injection destinations of the injection nozzle 211 are the four side surfaces of the casing 18. The injection nozzles 213 are provided in two rows (for example) on the ceiling surface of the casing 18. The spray nozzle 213 is directed so as to focus on the side surfaces (two surfaces) parallel to the screen where crumbs are likely to adhere.
 液体噴射機構22は、(図示しない)液体源に接続される配管222と、その先端に設けられた噴射ノズル221で、構成される(図1A、図1B、及び図5Aを参照)。噴射ノズル221は、ケーシング18の底面であって出口側(延長管13の側)の角部分(隅部分)に、(例えば)4つ設けられる。噴射ノズル221の噴射先は、ケーシング18の側面の下側、及び底面である。液体噴射機構22の4つの噴射ノズル221は、噴射位置がずれるように取り付けられており、これによって液体の噴射流51の衝突・相互干渉を防止し、効率よく、液体をケーシングの底面と側面の下側へ衝突させて、クラムの付着・凝集を防止している。図5Bに示される態様では、4つの噴射ノズル52は、噴射位置が同じになっていて、液体の噴射流51が衝突し相互に干渉してしまっている。又、スクリーン11でクラムと分離された熱湯は、スクリーン11の片側(スクリーン11が回転し、クラムがある側)で多く分離されるため、熱湯の流れは片側に偏り易い。そのため、ケーシングの底面にて、流れのムラが生じてしまい、流れの弱い(流量の少ない)箇所は、スクリーンの目から抜け出たクラムや壁面から剥がし落とされたクラム53が堆積し易い。これに対し、液体噴射機構22のように、液体の噴射位置を調整し、噴射される液体どうしが互いに干渉しないような構造をとれば、このような問題は生じない。 The liquid ejecting mechanism 22 includes a pipe 222 connected to a liquid source (not shown) and an ejecting nozzle 221 provided at the tip thereof (see FIGS. 1A, 1B, and 5A). Four (for example) four injection nozzles 221 are provided at the corner portion (corner portion) on the bottom side of the casing 18 and on the outlet side (the extension pipe 13 side). The injection destinations of the injection nozzle 221 are the lower side and the bottom surface of the side surface of the casing 18. The four injection nozzles 221 of the liquid injection mechanism 22 are mounted so that the injection positions are shifted, thereby preventing collision and mutual interference of the liquid injection flow 51, and efficiently supplying the liquid to the bottom and side surfaces of the casing. Colliding with the lower side prevents crumbs from sticking or clumping. In the mode shown in FIG. 5B, the four injection nozzles 52 have the same injection position, and the liquid injection flow 51 collides and interferes with each other. Further, since the hot water separated from the crumb by the screen 11 is largely separated on one side of the screen 11 (the side on which the screen 11 rotates and the crumb is present), the flow of hot water tends to be biased to one side. Therefore, unevenness of the flow occurs on the bottom surface of the casing, and the crumb 53 that has come off from the eyes of the screen or the crumb 53 that has been peeled off from the wall surface easily accumulates at a weak flow (low flow rate) location. On the other hand, such a problem does not occur if the liquid ejecting position is adjusted and the ejected liquids do not interfere with each other as in the liquid ejecting mechanism 22.
 液体噴射機構23は、液体噴射機構17と概ね同じ位置に配設される。この液体噴射機構23は、(図示しない)液体源に接続される配管232と、その先端に設けられた噴射ノズル231で、構成される(図1A及び図1Dを参照)。配管232は、延長管13において(スクリーン11の出口近において)、上方から円筒状のスクリーン11(延長管13)の軸方向に垂直な面(円形)の中心に伸びるように配設される。そして、中心に(配管232の先端に)、(例えば)1つの噴射ノズル231が設けられる。噴射ノズル231の噴射先は、延長管13の内周面下側である。 The liquid ejecting mechanism 23 is disposed at substantially the same position as the liquid ejecting mechanism 17. The liquid ejecting mechanism 23 includes a pipe 232 connected to a liquid source (not shown) and an ejecting nozzle 231 provided at the tip thereof (see FIGS. 1A and 1D). In the extension pipe 13 (near the exit of the screen 11), the pipe 232 is disposed so as to extend from above to the center of a surface (circular) perpendicular to the axial direction of the cylindrical screen 11 (extension pipe 13). At the center (at the tip of the pipe 232), (for example) one injection nozzle 231 is provided. The injection destination of the injection nozzle 231 is below the inner peripheral surface of the extension pipe 13.

Specifically, SUS304, SUS316 (Japanese Industrial Standard) and the like. It is particularly preferable to use low carbon stainless steel. The roller of the drive mechanism 12 is preferably made of a high-strength resin material (engineering plastic). Specific examples include MC nylon (registered trademark, polyamide resin).
 次に、本発明に係るゴム素材の製造方法について、ブタジエンゴムの場合を例にして説明する。又、それを通じて、上記固体状重合体用分離装置1を使用する場合を例にして、本発明に係る固体状重合体の分離方法についても、説明する。 Next, the method for producing a rubber material according to the present invention will be described by taking the case of butadiene rubber as an example. In addition, through this, the solid polymer separation method according to the present invention will be described by taking the case of using the solid polymer separation device 1 as an example.
 先ず、ブタジエンモノマー(1,3-ブタジエン)を入手する。これは、一般に原油から取り出されるナフサの熱分解によって(副産物として)生産される他、エチレンから製造される。このブタジエンモノマーを、脱水精製したトルエン、あるいはベンゼン、キシレン等の溶媒と混合し、更にニッケル系の触媒、あるいは他のチタン系、コバルト系、ネオオジウム系、リチウム系等の触媒を添加し、重合し、ブタジエン重合体を得る。そして、メタノール等の重合停止剤や必要な老化防止剤を加えた後、105~200℃の蒸気を作用させ、溶媒を除去する。 First, a butadiene monomer (1,3-butadiene) is obtained. In addition to being produced by pyrolysis of naphtha that is generally extracted from crude oil (as a by-product), it is produced from ethylene. This butadiene monomer is mixed with dehydrated toluene or a solvent such as benzene or xylene, and then a nickel catalyst or another catalyst such as titanium, cobalt, neodymium, or lithium is added and polymerized. A butadiene polymer is obtained. Then, after adding a polymerization terminator such as methanol and a necessary anti-aging agent, steam at 105 to 200 ° C. is applied to remove the solvent.
 ここで、ブタジエン重合体は、クラム(小さな塊)の状態で、蒸気由来の熱湯の中に分散した状態となっている。そこで、固体状重合体用分離装置1を用いて、ブタジエン重合体を熱湯から分離する。この分離は、固体状重合体用分離装置1を、スクリーン11の円周方向であって案内板15の螺旋状の向きに合う方向に、スクリーン11を回転させておき、スクリーン11の入口(駆動管123の側)から、熱湯の中に分散したブタジエン重合体を連続的に投入すればよい。そうすると、熱湯はスリット112を通過して、ケーシング18の排出口182から排出され、一方、ブタジエン重合体は、熱湯から分離され、スクリーン11の内周面に残り、螺旋状の案内板15の案内に従って、定量ずつ、スクリーン11の出口(延長管13の側)から、次工程へ移送される。 Here, the butadiene polymer is in a crumb (small lump) state and is dispersed in hot water derived from steam. Therefore, the butadiene polymer is separated from hot water by using the solid polymer separation device 1. In this separation, the solid polymer separator 1 is rotated in the circumferential direction of the screen 11 and in the direction matching the spiral direction of the guide plate 15, and the entrance (drive) of the screen 11 is driven. A butadiene polymer dispersed in hot water may be continuously added from the side of the pipe 123). Then, the hot water passes through the slit 112 and is discharged from the discharge port 182 of the casing 18, while the butadiene polymer is separated from the hot water and remains on the inner peripheral surface of the screen 11 to guide the spiral guide plate 15. Accordingly, a fixed amount is transferred from the outlet of the screen 11 (side of the extension pipe 13) to the next process.
 その後、ブタジエン重合体を、脱水装置で更に脱水した後、乾燥装置で乾燥させ、(例えば)プレス成形装置で、所定のブロック形状に成形し、必要なラッピングを施せば、ゴム素材(中間製品)が得られる。 After that, the butadiene polymer is further dehydrated with a dehydrating device, dried with a drying device, formed into a predetermined block shape with a press molding device (for example), and if necessary lapping is performed, a rubber material (intermediate product) Is obtained.
 本発明に係る固体状重合体用分離装置は、種々のゴム製品の製造過程において、液体中に分散した固体状重合体を、その液体から分離する手段として、好適に利用される。 The separation device for a solid polymer according to the present invention is suitably used as a means for separating a solid polymer dispersed in a liquid from the liquid in the production process of various rubber products.
