Abstract:
This punching metal drum screening device (100) has: a cylindrical body part (10) that has a central axis (10A) arranged in an approximately horizontal direction and a wall surface formed of a punched metal; a first closing plate (20B) that closes one end side of the body part (10); a to-be-treated liquid introduction tube (11) for supplying a to-be-treated liquid through the first closing plate (20B); a supply part (17) that is connected to the to-be-treated liquid introduction tube (11) and receives the to-be-treated liquid; a second closing plate (20A) that closes the other end side of the body part (10); support bodies (12a, 12b) that support the body part (10) to be rotatable around the center axis (10A); and a driving means (13) for rotating the body part (10). The supply part (17) changes the flow of the to-be-treated liquid toward the outside in the radial direction of the body part and disperses the flow, and drops the to-be-treated liquid onto a wall surface including at least the vicinity of the first closing plate (20B).
