<p>PROBLEM TO BE SOLVED: To provide a vertical type solid-liquid separation machine in which cleaning process is automated, whereby manpower saving and unmanned operation can be achieved.SOLUTION: A vertical type solid-liquid separation machine 10 for carrying out solid-liquid separation comprises: a screw conveyor 12 which is rotatably supported in a cylindrical rotary bowl 11 rotatably supported onto an outer cylindrical case 13; a main velocity electric motor 22; a differential velocity electric motor 24; and a stock solution supply pipe 15 for supplying stock solution 17. The machine 10 is equipped with: a cleaning liquid supply device 26 for supplying cleaning liquid 9 to the stock solution supply pipe 15; and a cleaning execution device 30 which carries out a cleaning process C in which the cleaning liquid 9 is supplied to the stock solution supply pipe 15 by the cleaning liquid supply device 26, and the cleaning liquid 9 is discharged from at least one of a separated liquid discharge port 13a and a solid content discharge port 11c while the rotary bowl 11 and the screw conveyor 12 being rotated with a differential velocity generated by the differential velocity electric motor 24.</p> |
