Abstract

725,333. Filters. PASSAVANT, W., [trading as PASSAVANT-WERKE KOMMANDIT-GES.]. March 3, 1953 [April 8, 1952], No. 5889/53. Class 46. The screening surface of a drum screen, which is open at the supply end and which rotates about a horizontal axis, is formed by basket-like or box-like screening members. Fig. 2 shows a drum screen 25 looking from the open to the closed end 6. Located on the circumference are screening-basket supports 7 covered with screening material 8 and secured replaceably to the drum. The drum is rotated on rollers 11 and 12 by a motor 17 and has projecting within it a collecting trough 14 for the screened material carried along by the baskets 8 and bars 40 as a result of rotation of the drum. Jet pipes 15 discharge washing liquid. The screening baskets are preferably closed at their ends..
