The present invention relates to a sludge removable device having a cleaning filter. More specifically, the sludge removable device includes a cylindrical screen, a driving part, a sewage supplying part, a sludge discharge part, a waste water discharge part, a cleaning unit, and a waste water filtering unit. The cylindrical screen has one end portion through which sewage including sludge is introduced, an opposite end portion, through which the de-watered sludge is discharged, and a plurality of dehydration holes to drain waste water. The driving part rotates the cylindrical screen; The sewage supplying part supplies the sewage including the sludge into the one end portion of the cylindrical screen. The sludge discharge part discharges the sludge discharged through the opposite end portion of the cylindrical screen. The waste water discharge part to discharge waste water discharged through the dehydration holes of the cylindrical screen. The cleaning unit cleans the cylindrical screen using the waste water of the waste water discharge part. The waste water filtering unit filters the waste water to be supplied to the cleaning unit. As describe above, according to the present invention, the waste water discharged through the cylindrical screen is filtered thereby preventing the cleaning nozzle from being clogged and used to smoothly clean the cylindrical screen. Accordingly, costs required to clean the cylindrical screen as the cleaning nozzle is clogged can be reduced, and the cleaning efficiency of the cylindrical screen can be improved. Accordingly, the removal efficiency of the sludge can be improved. |
