Abstract

Disclosed is an electro-penetrative type sludge weight reducing apparatus, which can uniformly dehydrate sludge by gradually applying the same pressure over an entire surface of the sludge and applying the same voltage to the sludge and includes a sludge supplier, which can minutely and precisely control a compression height for the sludge according to characteristics and a thickness of the sludge and maximize a moisture reducing efficiency of the sludge by uniformly supplying the sludge having a desired thickness to an entire width of a conveyor belt and an electrode plate with improved insulation safety.

Abstract

The present invention discloses an electro-penetrative type sludge weight reducing apparatus which applies the same pressure all over the sludge in stages and applies the same voltage to the sludge in order to uniformly dehydrate the sludge, and which controls the compressed height of the sludge in a fine and precise manner in accordance with the characteristics and thickness of the sludge. The apparatus comprises: a sludge feed unit which feeds the sludge in a desired thickness uniformly to the whole width of a conveyor belt to maximize the efficiency of moisture reduction in the sludge; and an electrode plate with improved insulation safety.
