Claims4
In a liquid-solid separator having a tank arranged to receive liquid-solid material delivered in surges with entrained air and separator screen means for separation of solids from liquid, said screen means being positioned to receive a controlled flow of liquid-solid material from overflow weir means in said tank, the improvement which comprises an extension of said tank vertically above said weir means, said extension being in the form of a closed upward extension of the tank, said extension being divided by vertical partitions into a plurality of separated compartments above the weir means, whereby surges of material into the tank rise freely upward without restriction while being confined against lateral movement by said partitions.
In a liquid-solid separator having a separating screen and a holding tank connected to a source of solids-containing liquid delivered in surges with entrained air and positioned to distribute said liquid to the separator screen through an opening at a side of the holding tank, the improvement which comprises surge receiver means mounted directly on and above the holding tank, said surge means being in the form of a closed upward extension of the holding tank having a plurality of vertically disposed baffles which divide the upper part of the holding tank into separate compartments whereby surges of liquid in the tank rise freely upward while being confined by said baffles.
