<p>PROBLEM TO BE SOLVED: To certainly eject a pressurized fluid such as air and nitrogen to remove adhered and accumulated materials to vanes of a centrifugal impeller in a device for dry opening waste paper. SOLUTION: In this device for dry opening waste paper, an operating valve 10 is directly connected to an inlet 3a for a pressurized fluid of a fluid ejection hole 3 made on a cylindrical casing 1 having a centrifugal impeller and a clogging of the fluid ejection hole 3 can be solved by simply blowing off clogged materials P from the fluid ejection hole 3 by feeding the pressurized fluid by operating the operating valve 10, as the interval from the operating valve 10 to the inside of the cylindrical casing 1 is short and the amount of the clogged materials P are little, even when the clogged materials P cause the clogging by opened products of source waste paper and powdery fiber.</p> |
