ELECTROPHORETIC ELECTRO-OSMOSIS DEHYDRATOR CAPABLE OF SMOOTH SLUDGE INJECTION ACCORDING TO FLUIDITY
The present invention relates to an electrophoretic electro-osmosis dehydrator capable of smooth injection of highly fluidic sludge. The present invention comprises: a variable portion disposed at the lower portion of a sludge supply portion in a space between caterpillar portions, wherein the variable portion includes a cylinder which applies power in a variable manner according to the fluidity of the supplied sludge and a sprocket of which one side is hinge-fixed in a rotatable manner to an external frame and the other side is connected to the cylinder and configured to be in contact with the caterpillar portion; and a plurality of idle sprocket portions disposed in the space between the caterpillar portions so as to drive the caterpillar portions. As a result of the power applied to the cylinder, the sprocket is rotated by the hinge so that the gap between a drum and the caterpillar portion varies. Different pneumatic pressures are applied to the cylinder according to the fluidity of the sludge so as to variably change the gap between the drum and the caterpillar. Thus, sludge injection can be facilitated, sludge does not overflow and contaminate the facilities, and the sludge treatment volume can be increased.
