Abstract:
1. A solid-liquid separating apparatus for separating a slurry into a solid component and a liquid component, which apparatus comprises: a mold unit having a cylindrical mold cavity defined therein for accommodating the slurry and also having first and second open ends opposite to each other; a gate for selectively opening and closing the second open end of the mold unit; and a pressing rod slidable into the cavity of the mold unit to urge the slurry against the gate, then held in position to close the second open end of the mold unit, to thereby compress the slurry; wherein while fibrous solid-liquid separating filters are placed in the mold unit so as to seal a gap, delimited between an inner peripheral surface of the mold unit and an outer periphery of a leading end of the pressing rod, and another gap delimited between respective contact surfaces of the gate and the mold unit, respectively, the pressing rod is driven into the mold cavity to compress the slurry within the mold unit, and a resultant solid component is ejected out of the mold unit together with the solid-liquid separating filters, wherein the solid-liquid separating apparatus further comprises: wherein the mold repositioning device comprises a guide rail, along which the traversing carriage is reciprocally moved along the predetermined path and a drive device for reciprocally moving the traversing carriage guided by the guide rail, wherein the filter mounting device performs placement of the upper and lower filters at the same indexed position, wherein the indexed position, at which the slurry is supplied by the slurry supply device, and the indexed position, at which the compression is performed by the pressing machine, are defined on respective sides of the indexed position, at which the upper and lower filters are placed, with respect to direction of movement of the traversing carriage, wherein the solid-liquid separating apparatus further comprises: wherein the gate and a discharge chute, through which the compressed solid component is discharged from the second open end of the mold unit, are mounted on the index base in such a manner as to allow the gate and the discharge chute to be selectively aligned with the second open of the mold unit by means of movement of the indexing base, and wherein the indexing base is brought into engagement with the first stopper, as the traversing carriage moves towards a position adjacent the first stopper, but is moved to change respective positions of the gate and the e chute relative to the second open end of the mold unit by means of continued movement of the traversing carriage.
