  • Apparatus for dewatering sludge
    Patent number: 5386768
    Abstract: An apparatus for dewatering sludge. The dewatering apparatus has a pressure plate device for compressing the sludge on a surface such that the sludge is dewatered. The dewatering apparatus also has a device for confining the sludge within a predetermined area on the surface as the pressure plate device compresses the sludge. The confining device is disposed adjacent to the pressure plate device. Preferably, the dewatering apparatus also has a device for transporting the sludge on a belt to the pressure plate device. The belt is preferably a porous belt filter cloth. For instance, the transporting device can have a first conveyor belt device and a second conveyor belt device having the belt. The first conveyor belt device transports partially dewatered sludge, or sludge cake, from a belt filter press to the second conveyor belt. The second conveyor belt device transports the sludge from the first conveyor belt device to the pressure plate device on the belt.
