Chain bucket skimmer

A chain bucket skimmer for removing a floating matter floating in a liquid, comprising:

• an endless chain moving between a downward end located below a liquid surface of the liquid and an upward end located above the liquid surface;
• a bucket attached to the chain and including an opening into which the liquid flows and a liquid storage portion storing the liquid, the opening facing upward when the bucket moves from the downward end toward the upward end and the opening facing downward when the bucket passes through the upward end and moves toward the downward end;
• a chain bucket unit including the chain, the bucket, a bucket ascending portion moving from the downward end to the upward end, and a bucket descending portion moving from the upward end to the downward end;
• a drive unit moving the chain bucket unit;
• a first fan arranged at a position in contact with the liquid surface and rotating about a rotation shaft to move the liquid toward the chain bucket unit in a first direction;
• a second fan arranged on a side opposite to the first fan with the chain bucket unit interposed therebetween and rotating about the rotation shaft to move the liquid toward the chain bucket unit in a second direction;
• a first flow control member facing the bucket ascending portion in a horizontal direction, extending from the liquid surface to the liquid, arranged over the first fan and the second fan at a height corresponding to heights of the first fan and the second fan, and moving a part of the liquid and the floating matter moved by rotation of the first fan and the second fan, toward the bucket ascending portion;
• a second flow control member facing the bucket descending portion in the horizontal direction, extending from the liquid surface to the liquid, arranged over the first fan and the second fan at the height corresponding to the heights of the first fan and the second fan, and moving a part of the liquid and the floating matter moved by rotation of the first fan and the second fan, toward the bucket descending portion;
• a first inflow portion, which is formed between the first fan and the second fan, in which the bucket ascending portion is arranged, and which contains the liquid and the floating matter that have flowed into the inside of the first flow control member;
• and
• a second inflow portion, which is formed between the first fan and the second fan, in which the bucket descending portion is arranged, and which contains the liquid and the floating matter that have flowed into the inside of the second flow control member.
