Problems solved by technology

Since the diaphragm cavity is composed of a diaphragm filter plate, the deformation of the squeezed diaphragm cavity is limited, and the deformation of the diaphragm filter plate (such as the periphery and the middle of the filter plate) is inconsistent, and the sludge is not evenly squeezed

Abstract

The present invention provides a press filter plate for electroosmotic sludge high-dry dewatering equipment, comprising a filter plate frame, filter cloth, filter disc and concentric holes for conveying sludge, and the front of the filter plate frame is unidirectionally recessed A filter press chamber is formed, the filter disc is placed at the bottom of the filter press chamber, the filter is arranged on the filter disc, the cathode conductive filter screen connected to the cathode copper row is arranged between the filter disc and the filter cloth, and the back of the plate frame An anode plate is provided; a cavity that can be filled with liquid or gas is arranged between the filter disc and the plate frame, and a push plate device is also arranged between the cavity and the filter disc. The tympanic membrane is placed on the four peripheries of the inner edge of the basic steel plate. The invention increases the pressing pressure of the sludge by filling the body with water to press, and at the same time, the pushing plate device ensures the uniform pressing force, realizes the whole pressing, and further reduces the water content of the sludge.

Description

technical field [0001] The invention relates to the field of sludge disposal equipment components, in particular to a filter chamber mechanism in a sludge electro-osmosis high dryness dewatering equipment. Background technique [0002] On the market, most of the sludge dewatering equipments use plate and frame diaphragm pressure filtration. Due to the need to add lime, iron salt and other agents for the dewatering of the plate and frame diaphragm filter press sludge, it is difficult for the treated sludge to meet the national pollution control standards. Buried disposal. Moreover, the addition of chemicals to sludge reduces the calorific value of sludge as fuel, which is not conducive to the disposal and utilization of sludge in the later stage. [0003] The filter chamber mechanism in the sludge high-dry dehydration equipment of the existing equipment is pressed, relying on the oil cylinder to push the spring to compress to reduce the volume of the filter chamber, and to ...
