Description

【０００１】
【産業上の利用分野】
本発明は、各種の混合機，攪拌機，分散機等で使用するタンクを好適に洗浄できるようにしたタンク洗浄機に関するものである。
【０００２】
【従来の技術】
印刷インキ，顔料，シ−リング剤，接着剤等の製造に際しては、各種の原材料をタンク内で攪拌，混合等し、取出口から製品を取り出した後、タンクの内面等に付着した材料を洗浄機で洗浄している。このような洗浄機として、例えばブラシを先端に有するア−ムを回転軸に取り付け、タンク内に該回転軸を差し入れて回転し、遠心力によって上記ブラシをタンクの内壁に押し付けながら該タンクの内周に沿って回転させる装置が知られている。しかし、この種の洗浄機ではブラシの同一個所がタンクの内壁に摺接するだけであり、また押圧力も弱いので、付着物が低粘度材料の場合には洗浄することができても粘度が高い材料の場合には充分ではなく、特にタンク内に嵌合させた加圧盤で加圧しなければ製品を取出口から押し出すことができないような超高粘度材料が付着している場合には上記の如き洗浄機では殆んど不可能であった。
【０００３】
【発明の解決課題】
本発明の目的は、タンク内に付着した材料が高粘度材料であっても確実に洗浄できるようにしたタンク洗浄機を提供することである。
【０００４】
【課題解決の手段】
