Sewage sludge electromagnetic force filter dewatering device

Abstract

The invention relates to a sewage sludge electromagnetic force filter dewatering device which comprises a plurality of pressure filter chambers, each pressure filter chamber comprises an intermediatemain filter plate (9) and an intermediate secondary filter plate (10), electromagnetic modules are arranged on the intermediate main filter plate (9) and the intermediate secondary filter plate (10),and the intermediate main filter plate (9) and the intermediate secondary filter plate (10) in the same pressure filter chamber are mutually attracted through the electromagnetic modules; the adjacentpressure filter chambers are communicated with each other through a hose (12), and the hose (12) is communicated with a sludge inlet pipe; a limiting rope (31) for limiting maximum displacement between the two filter plates is arranged between the adjacent two filter plates; each electromagnetic module comprises an electromagnetic core (6) and an electromagnetic coil (7), the electromagnetic coil(7) is arranged on the corresponding electromagnetic core (6) in a winding manner. The sewage sludge electromagnetic force filter dewatering device provided by the invention adopts electromagnetic force and has the advantages of being less in quick-wear part, free from hydraulic system, low in energy consumption and relatively low in moisture content of dewatered sludge.

Description

technical field [0001] The invention relates to the field of sewage sludge treatment, in particular to an electromagnetic pressure filter dehydration device for sewage sludge. 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 filter pl...
