Optimization device for the discharge timing of concentrate from vertical centrifuge

Abstract

The present invention addresses the problem of providing an apparatus for optimizing the discharge timing of a vertical centrifuge concentrate, which can suppress the outflow of microorganisms and appropriately optimize the timing of the discharge of the concentrate when the discharge valve is opened. This problem is solved by having a structure in which the concentrate is discharged via a heavy liquid discharge pipe (23) connected to a heavy liquid impeller (22) facing the heavy liquid chamber (21), and a structure in which the clarified liquid is discharged via a discharge pipe (20) connected to a light liquid impeller (19) facing the light liquid chamber (18), thus continuously discharging the concentrate. An optimization device for the timing of concentrate discharge of a vertical centrifuge (1) that supplies raw liquid and discontinuously obtains concentrate includes: a structure that starts the concentration of concentrate while closing the heavy liquid discharge valve (26) installed on the heavy liquid discharge pipe (23) to forcibly stop the discharge of concentrate; a sensing device (4) that detects the clarified liquid discharged from the light liquid chamber (18) and obtains the detected sensing information; and a device that controls the heavy liquid discharge valve (26) based on the obtained sensing information to discharge and stop the discharge of concentrate.
