PURPOSE: A device for displaying a sludge loading quantity for securing an efficient vacuum force in a dredger of a waste water container is provided to utilize a vacuum force without wasted energy consumption by referring to the loading quantity of the sludge and to prevent damage to a vacuum pump by stopping the pump when the sludge is filled to capacity. CONSTITUTION: A device for displaying a sludge loading quantity for securing an efficient vacuum force in a dredger of a waste water container comprises an arm holder(10), a float arm(20), a float(30), an index indicator, and an index plate(50). The arm holder is installed to pass through a sludge tank(4). The float arm is installed to be rotated and passes through the arm holder. The float is coupled with the front end of the float arm. The index indicator is coupled with the front end of the flat arm. The index plate is attached to the exterior of the sludge tank and displays a sludge volume index. |
