[概要構成]
図1は、洗浄乾燥装置の第1実施形態を示す簡略構成図である。図2は、洗浄乾燥装置の上面図である。図3は、洗浄乾燥装置の上方向からみたXY断面図である。
(被処理物、洗浄液)
被処理物は、例えば、樹脂からなる。これによれば、被処理物は、水と分離しやすくなり、撹拌翼20の回転数を小さくしても被処理物を洗浄できる。したがって、撹拌翼20の洗浄時の負荷を低減できる。
洗浄液は、例えば、水である。なお、洗浄液は、エチルアルコールやメチルアルコールなどの有機溶剤であってもよい。
容器本体11は、筒状の側壁部111と、側壁部111の上側の第1開口部に取り付けられる天部112と、側壁部111の下側の第2開口部に取り付けられる底部113とを有する。側壁部111は、例えば、円筒形状である。天部112および底部113は、例えば、円板形状である。
撹拌翼20は、シャフト21と、シャフト21に沿って連続した螺旋を形成するようにシャフト21の周囲に巻回されたフィン22とを有する。具体的に述べると、シャフト21には、シャフト21の軸心に直交して延在する複数の支持部23が取り付けられ、フィン22は、支持部23に支持される。攪拌翼20は、シャフト21の軸心が容器本体11の中心軸11aに一致するように、容器本体11に取り付けられる。攪拌翼20は、中心軸11aを中心として自転する。上記構成によれば、フィン22は、連続した螺旋を形成するので、撹拌翼20による攪拌の程度を大きくすることができる。
フィルタ30は、洗浄液排出孔113bの容器本体11内側の開口部に取り付けられている。好ましくは、フィルタ30は、洗浄液と50μm以上の被処理物を濾別可能である。上記構成によれば、洗浄液と被処理物を濾別できる。フィルタ30は、例えば、ステンレスなどの金属、または、ポリエステルやポリエチレンなどの樹脂から構成される。フィルタ30のメッシュのサイズを調整することで、種々の大きさの被処理物を濾別することができる。
加熱器40は、容器本体11の側壁部111および底部112に設けられている。具体的に述べると、加熱器40は、複数の配管41を有し、複数の配管41は、側壁部111および底部112のそれぞれに埋め込まれている。配管41に、スチーム、オイルまたは温水などの熱媒体を流すことで、容器本体11内を加熱することができる。
制御装置5は、被処理物の洗浄時に攪拌翼20を回転させ、被処理物の乾燥時に攪拌翼20を回転させながら加熱器40を作動させる。好ましくは、制御装置5は、被処理物の洗浄時に加熱器40を作動させる。これによれば、洗浄時に昇温することで洗浄効果を向上できる。
なお、制御装置5は、被処理物の乾燥時の撹拌翼20の回転数を被処理物の洗浄時の撹拌翼20の回転数よりも小さくしてもよい。例えば、乾燥時の撹拌翼20の回転数は、30rpmであり、洗浄時の撹拌翼20の回転数は、50~100rpmである。これによれば、乾燥時では、洗浄液を含まないで被処理物だけを攪拌するため、被処理物の抵抗が大きくなるが、撹拌翼20の回転数を小さくすることで、撹拌翼20にかかる負荷をより低減することができる。
図3に示すように、フィルタ30は、底部113の外周113c側の領域に配置されている。底部113の外周113c側の領域とは、容器本体11の中心軸11aに沿った方向からみて、底部113の中心113dから側壁部111の内面111aまでの距離の半分よりも底部113の外周113c側の領域をいう。側壁部111の内面111aは、容器本体11の内部空間に面している。
次に、高分子の有機化合物からなる粉状の被処理物を洗浄液により洗浄し、被処理物を乾燥する洗浄乾燥方法について説明する。
図5は、洗浄乾燥装置の第2実施形態を示す撹拌翼の概略構成図である。図5に示すように、第2実施形態の洗浄乾燥装置において、撹拌翼20Aは、シャフト21と、シャフト21に沿って不連続な螺旋を形成するようにシャフト21の周囲に巻回された複数のフィン22とを有する。具体的に述べると、シャフト21には、シャフト21の軸心に直交して延在する複数の支持部23が取り付けられ、各フィン22は、各支持部23に支持される。螺旋方向に隣り合うフィン22,22は、離隔している。
なお、混合性能を向上するために、容器本体11の側壁部111の内面111aに中心軸11aに向けて板状の邪魔板を設置してもよい。
図6は、洗浄乾燥装置の第3実施形態を示す上面図である。第3実施形態は、第1実施形態とは、噴霧ノズルを設けている点が相違する。この相違する構成を以下に説明する。その他の構成は、第1実施形態と同じ構成であり、第1実施形態と同一の符号を付してその説明を省略する。
次に、上記洗浄乾燥装置を用いて洗浄を行った第1実施例を示す。第1実施例の結果を表1に示す。
次に、フィルタのサイズの最適値についての実施例を示す。
