Embodiment Construction

[0022] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] The electrodialysis oxidation diaphragm plate frame sludge dewatering machine of the present invention includes a main frame 14, a filter plate 2, an electric control box 6, a squeeze water main pipe 1 and a squeeze water pipe branch 4, a hydraulic device 5 and a hydraulic rod 13. The filter plate includes drainage holes 7, rare earth metal sheets 8, DC wires 9, filter plate side membranes 10, metal electrodes 11, press water return holes 3, sludge inlet 17 and water outlet 18.

[0024] A plurality of filter plates 2 are suspended on the main frame 14 in parallel through hanging ears 15 . The electric control box 6 controls the hydraulic device 5 to push the hydraulic rod 13 of the hydraulic device 5 to squeeze the filter plate 2 arranged on the main frame 14 . The filter plate 2 is made of rubber casting, with good flexibili...

Abstract

The invention discloses an electrodialysis oxidation method diaphragm sheet frame sludge dewatering machine which comprises a sludge dewatering machine, wherein the sludge dewatering machine comprises a main rack, a plurality of filtering plates, an electric control box, a sludge inlet, an extruded water tube, a hydraulic device, a hydraulic rod and a water outlet, wherein the plurality of filtering plates are arranged in parallel on the main rack; the outer surfaces of the filtering plates are covered with filtering cloth; the filtering plates are provided with drainage holes, rare earth metal pieces, direct flow guide lines, side filtering plate diaphragm pieces, metal electrode plates and extruded water backflow holes. According to the sludge dewatering machine, due to the adoption of an electric dewatering technique, cell water in sludge can be extracted, and the sludge dewatering effect of a high dry diaphragm sheet frame machine is improved.

Description

technical field [0001] The invention belongs to the field of sludge treatment, and in particular relates to a deep sludge dehydrator. Background technique [0002] Treatment and reuse of excess sludge from sewage treatment plants is a very important issue. At present, the commonly used sludge treatment technologies in the world are land use, landfill and incineration, etc. Due to the shortage of land resources and other environmental pollution problems, especially in large cities, the proportion of sludge land use and landfill is gradually decreasing, while incineration The proportion has increased, and it has gradually become one of the main sludge disposal methods in developed countries. The remaining sludge of domestic urban domestic sewage plants has high moisture content, high sand content, and low calorific value, resulting in low incineration efficiency, large corrosion to incinerators, and low calorific value utilization. The dehydrated sludge can bring a lot of co...
