- 10バールを上回る圧力と90℃を上回る温度を有する高粘性の溶融物用のスクリーンホイールフィルタを運転する方法であって、スクリーン挿入体(2)を保持するスクリーンホイール(1)と、該スクリーンホイール(1)に対応配置されていて該スクリーンホイール(1)を歩進的に回転駆動する回転駆動装置(12)と、逆洗クリーニングステーションとが設けられていて、該逆洗クリーニングステーションに、クリーニング剤の流れ方向において下流に配置されていてスリットノズルとして形成された逆洗ノズルを備えたクリーニング剤推進装置(9)が対応配置されていて、前記スリットノズルの有効開口が、前記逆洗クリーニングステーションに位置するスクリーン挿入体(2)を、その半径方向長さにおいてカバーしており、さらに、前記クリーニング剤推進装置(9)に作用する制御装置もしくは調整装置(7)が設けられており、クリーニング作用を有する逆洗を、スクリーンホイール(1)の回転中に行い、前記制御装置もしくは調整装置(7)は、クリーニング剤量及び/又はクリーニング剤圧及び/又はクリーニング剤流速度を、前記スクリーンホイール(1)の回転の時間経過に関連して、かつ/又は前記スクリーンホイール(1)の回転速度に関連して、かつ/又は溶融物通路(4)内のスクリーン挿入体(2)における差圧に関連して調節し、半径方向に対して垂直な方向における前記スリットノズル(5)の前記有効開口の寸法と、1つの駆動ステップ中に前記スクリーンホイール(1)が進む距離とを、前記スリットノズル(5)の前記有効開口の寸法が1つの駆動ステップ中における前記スクリーンホイール(1)の進む距離よりも小さくなるように、互いに調整し、さらに、前記スクリーンホイール(1)の回転のための始動プロセスに対して平行に、少なくともクリーニング剤圧を、前記スクリーンホイール(1)の回転中における圧力変化に対して高めるように調節することを特徴とする、スクリーンホイールフィルタを運転する方法。
- 前記逆洗クリーニングステーションにおけるクリーニング作用を有する前記逆洗を、前記スクリーンホイール(1)の回転中にかつ少なくとも時々前記スクリーンホイール(1)の停止中に行う、請求項1記載のスクリーンホイールフィルタを運転する方法。
