【発明の属する技術分野】
本発明は、製氷用冷却装置に係り、特に、蓄熱槽から冷却器へ供給される氷水から、氷分離器により氷を分離し、分離した水又は低濃度ブラインを供給して、スラリー状の氷水を生成する製氷用冷却装置に関する。
【0002】
【従来の技術】
従来の方法を図2に基づいて説明する。
図2は製氷用冷却装置のフロー構成図であり、1は冷凍サイクル、2は冷却器氷水搬送ポンプ、3は氷蓄熱槽、4は氷水流路、5は蒸発器(冷却器)、6は圧縮器、7は凝縮器を示す。
図2に示すように、氷蓄熱槽3に蓄えられた水又は低濃度ブラインは、冷却器氷水搬送ポンプ2によって冷凍サイクル1の蒸発器である冷却器5に搬送され、再び氷蓄熱槽3に戻される。製氷運転時、氷蓄熱槽3に蓄えられた、冷却器5に搬送する水又は低濃度ブラインの温度が低下(例えば0℃以下)した場合、水又は低濃度ブラインの一部は氷となり流体は氷水となる。前記のとおり製氷用冷却装置は、水又は低濃度ブラインをスラリー状の氷水を生成して蓄熱する方式であり、冷却器5に氷が搬送されると、氷が入ってくる分相対的に製氷能力が低下していた。このため蒸発温度、冷却能力、COPを低下させ、更には冷却器5内のチューブを閉塞し伝熱低下、凍結という問題があった。
【0003】
上記の問題に対して、氷を除去する方法として図3の方式が知られている。
図3は製氷用冷却装置のフロー構成図であり、1〜7は図2と同様である。25はストレーナ、26は掻き取り具、27は掻き取り具駆動用モータ、28は掻き取り具駆動軸を示す。
図3に示すように、氷蓄熱槽3内部にストレーナ25を取付、冷却器氷水搬送ポンプ2の吸込管を接続し、ストレーナ25外部には掻き取り具26が取付られている。掻き取り具駆動軸28を介して、掻き取り具駆動用モータ27で掻き取り具26を回転し氷を除去すると共にストレーナ外部に付着した氷を掻き取る方式である。
この方式は、ストレーナ25が氷蓄熱槽3内部にある為、メンテナンス時に氷蓄熱槽3内部を空にする必要等難があることと、駆動軸が長く製作費が高価であると共に、芯出し等の作業に時間を要していた。また、分離氷はストレーナ周囲にある為、分離後もすぐに氷着する機能上の問題があった。
【0004】
【発明が解決しようとする課題】
本発明は、上記従来技術の問題点を解消し、メンテナンスが簡単で、水と氷を良好に分離し、製氷能力が向上した製氷用冷却装置を提供することを課題とする。
【0005】
【課題を解決するための手段】
上記課題を解決するために、本発明では、水又は低濃度ブラインが通りスラリー状の氷水を生成する冷却器を蒸発器とし、該蒸発器と凝縮器と圧縮機とを接続して冷凍サイクルを形成すると共に、生成した氷水を溜める蓄熱槽を設け、該氷水を生成する冷却器と蓄熱槽とを、ポンプを有する循環する氷水流路で接続した製氷用冷却装置において、前記氷水流路に、内面洗浄ブラシと外面洗浄カッタとの間を回転するろ過円筒を有し、該ろ過円筒を駆動するモータを備えた氷分離器を設置し、該氷分離器で氷を分離した水又は低濃度ブラインを前記冷却器に供給する流路と、分離した氷を前記蓄熱槽内の氷密度の高い部分に戻す流路とを設けると共に、前記氷分離器に向う氷水流路に氷水の温度を検知する温度検知器を設置し、該検知した温度が前記水又は低濃度ブラインの氷点以上のときは前記モータを停止して前記の氷分離器を作動させない制御装置を設けることとしたものである。
【0006】
【発明の実施の形態】
本発明では、水又は低濃度ブラインが通りスラリー状の氷水を生成する冷却器を蒸発器とし、該蒸発器と凝縮器と圧縮機とを接続して冷凍サイクルを形成すると共に、生成した氷水を溜める蓄熱槽を設け、該氷水を生成する冷却器と蓄熱槽とを循環するポンプを有する氷水流路で接続した製氷用冷却装置において、前記氷水流路に氷分離器を設置し、冷却器に氷を分離した水又は低濃度ブラインを供給することとしたものである。
【0007】
次に、図面を用いて、本発明を詳細に説明する。
図1は、本発明の製氷用冷却装置のフロー構成図であり、図1において、1は冷凍サイクル、2は冷却器氷水搬送ポンプ、3は氷蓄熱槽、4、4’は氷水流路、5は蒸発器(冷却器)、6は圧縮器、7は凝縮器、9は氷分離器、10は回転ろ過円筒、11はらせん内面洗浄ブラシ、12は外面洗浄カッタ、13はろ過円筒駆動モータ、14はろ過円筒駆動軸、15は氷溜まり、16は氷戻し配管、17は氷戻し弁、18は氷分離器制御装置、19は氷水温度検出端、20は逆洗用配管、21は逆洗用ポンプ、22は氷分離器差圧検出器である。
【0008】
図1に示すように、氷蓄熱槽3に蓄えられた水又は低濃度ブラインは、冷却器氷水搬送ポンプ2によって冷凍サイクル1の蒸発器である冷却器5に搬送され、氷水流路4’を経由して再び氷蓄熱槽3に戻される。製氷運転時、氷蓄熱槽3に蓄えられた、冷却器5に搬送する水又は低濃度ブラインの温度が低下(例えば0℃以下)した場合、水又は低濃度ブラインの一部は氷となり流体は氷水となる。氷を除去するために通常のストレーナを取付けると、編目の部分に氷が付着して目詰まりし、連続的な運転が不可能であると共に、溜まった氷を戻す手段がない。本発明では、氷水中の氷を分離して氷蓄熱槽3に戻し、水又は低濃度ブラインを冷却器5に搬送している。
【0009】
氷分離器の構造は、らせん内面洗浄ブラシ11と外面洗浄カッタ12の間に回転ろ過円筒10を回転させ、氷水を流し、氷の目詰まりを自動的に防止する方法で氷を分離するものである。前記動作により、冷却器5には氷を分離した水又は低濃度ブラインを流し、分離された氷は氷溜まり15を通り、氷戻し配管16、氷戻し弁17を介して氷蓄熱槽3に戻される。
【0010】
水又は低濃度ブラインの温度が氷点以上の場合は、特に氷分離器9を運転する必要がないので、氷水温度検出端19にて、氷水の温度を検知して氷分離器制御装置18に伝達し、ろ過円筒駆動モータ13を停止して、氷戻し弁17を閉とする。また、まれに回転ろ過円筒10の外側に氷が付着することがある。その場合、氷分離器9の氷水入口出口の差圧が増大するため、氷分離器差圧検出器22で差圧を検知して、逆洗ポンプ21を運転して回転ろ過円筒10の外側の氷を除去する。
本装置は、氷蓄熱槽3の外部にあるためメンテナンスの際に、氷蓄熱槽3より氷水を抜く必要がなく容易に行うことが可能である。
【0011】
【発明の効果】
本発明によれば、製氷運転時、氷蓄熱槽3に蓄えられた、冷却器5に搬送する水又は低濃度ブラインの温度が低下(例えばO℃以下)した場合でも、冷却器には氷を除去した、水又は低濃度ブラインを搬送することが可能であると共に、除去された氷は氷蓄熱槽に戻されるため製氷能力が増加し、立上がり時間が短縮でき、更には冷却器のチューブの閉塞がなく、凍結を防止できるという効果を奏
する。
