Abstract

The invention relates to an electromagnetic force-based dehydration apparatus for reduction of sewage sludge. The apparatus comprises a front auxiliary filter board (7), a rear auxiliary filter board (19), intermediate main filter boards (11), intermediate auxiliary filter boards (10), electromagnetic iron cores (4) and solenoid coils (5), wherein the solenoid coils (5) are wound on the corresponding electromagnetic iron cores (4) to form electromagnetic modules; the outer side of the front auxiliary filter board (7) is provided with one electromagnetic module; the inner side of the rear auxiliary filter board (19) is provided with one electromagnetic module; a plurality of filter board modules are arranged between the front auxiliary filter board (7) and the rear auxiliary filter board (19); and each filter board module comprises one intermediate main filter board (11), one intermediate auxiliary filter board (10) and one electromagnetic module. The electromagnetic force-based dehydration apparatus provided by the invention employs electromagnetic force and has the advantages of few vulnerable parts, no need for a hydraulic system, low energy consumption and low water content of dehydrated sludge.

Description

technical field [0001] The invention relates to the field of sewage sludge treatment, in particular to a sewage sludge reduction and dehydration device based on electromagnetic force. Background technique [0002] In the prior art, the most advanced sludge dewatering equipment on the market is the diaphragm plate and frame filter press. During dehydration, the efficiency is low, and the pressing pressure is only 1.6MPa. The high-pressure water pump injects water into the diaphragm plate and frame. , The diaphragm is bulged to reduce the area of ​​the filter chamber, and the diaphragm plate frame is squeezed by the plastic deformation of the plate frame; the compression ratio of the diaphragm plate frame is small, and the relative working cycle is long. In addition, in terms of the structural structure of the common elastic press plate frame on the market, the filter plate is an integral injection molded part, the filter plate is easily damaged and deformed, and the damaged f...
