Estimating the term…
A settling tank having a flat bottom and an inclined side extending from an arcuate corner along one side of said bottom, a drag-out conveyor means along said bottom around said arcuate corner and up said inclined side, and a mechanism for permitting the idler sprocket or roller of the conveyor to move away from said arcuate corner to prevent jamming, as well as to control the thickness and/or to sense the drag of the settlings on the bottom of the tank. This conveyor hold-down control mechanism comprises an adjustable elongated means parallel to said inclined side, pivoted at one end above the normal surface of liquid in said tank, and at the other end to the idler sprockets or rollers for the conveyor at the arcuate corner, for normally resiliently urging said idlers into said corner, as well as indicating when said idlers move away from said corner by encountering foreign objects which otherwise would jam the conveyor. This movement of said idlers may be directed by a lever forming a toggle arrangement, the knee of which is at the axis of said idlers; or it may be directed by guide means for the axis of said idlers fixed to the opposite sides of said tank. The lever forming the toggle arrangement may be pivoted to a shaft for the idlers along the bottom of the tank, or to the opposite sides of the tank. The indication of the movement of said toggle may be visual and/or audible as well as including means for controlling, cycling and/or stopping the operation of the drag-out conveyor.
A hold-down mechanism for a drag-out conveyor along the bottom and the ramp side of the settling tank, comprising:
In a settling tank having a bottom and a sloping side and a drag-out conveyor along said bottom and up said sloping side for removing settlings from a contaminated liquid in said tank, said conveyor having parallel flights extending transversely between parallel reaches of sprocket chain extending around at least a pair of driving sprockets at the upper end of said sloping side and a pair of idlers at opposite ends of the bottom of said tank, the bottom idlers at the bottom of said sloping side being floating, the improvement comprising:
In a settling tank having a bottom and an adjacent ramp side and a drag-out conveyor along said bottom and up said ramp side, the improvement comprising:
A hold-down mechanism for a drag-out conveyor along the bottom and ramp side of a settling tank, comprising:
In a settling tank having a bottom and a sloping side and a scraper conveyor for removing settlings from said bottom and up said side out of said tank, said conveyor having parallel supporting shafts at least at the ends of said bottom and near the top of said sloping side, the improvement comprising a mechanism for said conveyor for resiliently urging said conveyor against the juncture between said bottom and said sloping side, said mechanism comprising:
