Abstract
A contaminated fluid recovery apparatus includes a dirty tank, a conveyor, and a drum-shaped filter unit. Inlet ports of the drum-shaped filter unit open along an axis of a magnet drum. The conveyor scrapes out an object for removal settled on a bottom portion of the dirty tank toward an exit section. The conveyor includes a lower portion which moves along the bottom portion and an upper portion which passes over the lower portion. The magnet drum is located horizontally between the lower portion and the upper portion of the conveyor so that its axis is perpendicular to a direction of travel of the conveyor. The magnet drum is driven by a chain of the conveyor.
