Abstract:
1. An electro-penetrative type sludge weight reducing apparatus comprising: a frame having a predetermined shape; a filter cloth conveyor configured to infinitely rotate a filter cloth and formed in a lengthwise direction of the frame; a sludge supplier configured to supply sludge to an upper portion of the filter cloth and formed in one side of the filter cloth conveyor; a dehydrator for compressing sludge supplied to an upper portion of the filter cloth conveyor by first and second electrode parts, applying a voltage, and forming an electric field to dehydrate the sludge, the dehydrator including the first electrode part formed above the filter cloth conveyed by the filter cloth conveyor and the second electrode part formed under the filter cloth to face the first electrode part; a driver configured to elevate the dehydrator and fixedly formed on the frame above the dehydrator; and a controller for controlling the driver to control a compression height of the dehydrator for the sludge and controlling a voltage applied to the first and second electrode parts, wherein the dehydrator dehydrates the sludge supplied to the upper portion of the filter cloth conveyor by a substantially identical pressure and voltage, and the driver is interworked with rotation of a driving motor to elevate the first electrode part, the driver including a fixing plate fixedly formed on the frame, at least two screw jacks inserted through one side of the fixing plate to be fixedly coupled to one side of the first electrode part, interworking shafts for providing rotation force to the screw jacks, a gear box for changing a speed of the rotation force provided to each of the interworking shafts, and a driving motor for providing rotation force to the gear box.
