  • Sedimentation tank with raking structure
    Patent number: 4053421
    Abstract: A raking structure for moving settled solids to a discharge opening in the bottom of a sedimentation tank is disclosed herein. The raking structure consists of a rotatable member and a rake arm pivoted on the rotatable member along an inclined pivot axis with a counterweight connected to the rake arm through cable means so that the torque load required to cause the arm to pivot can be varied. The rake arm may also have means for varying the buoyancy of the rake arm and thereby vary the torque or moment compound required to pivot the rake arm with respect to the rotatable member.
