Sludge dewatering machine is suitable for urban sewage treatment plants, pharmaceutical, electroplating, paper, leather, printing and dyeing, metallurgy, chemical industry, slaughtering, food, wine manufacturing and environmental projects in the wastewater treatment sludge dewatering process, but also in industrial production can be used for solid-liquid separation of the occasion, is the ideal equipment environmental management and resource recovery. Design features a main design features: ※ rational design: compact frame structure, the area greatly reduced. Yet robust, easy maintenance, guide rollers level of patchwork, often lower part of the operating position, the whole structure neat appearance. ※ beautiful, practical appearance: machine designed, stainless steel guard outside, completely avoid the huge volume of traditional tape machine, running mud, running water, poor working conditions and other defects. ※ excellent corrosion resistance: the parts in contact with water made of stainless steel, frame made of stainless steel or galvanized steel A3 standard (zinc coating thickness not less than 80μm) embalmed, no rust to achieve the whole site, to ensure that no rust within five years . Second, the special design: 1, The machine adopts large diameter dewatering zone in transition arc dehydration technology specifically designed to enable the filter with the pressure gradually increased, to effectively prevent mud run phenomenon, therefore, can greatly improve the sludge processing amount. 2, frame compact design, the use of S-type installation guide rollers, so that the whole volume is reduced, better dewatering. 3, thickener structure is simple, low failure rate, stable operation, a special filter selection, pre-dehydration effect. 4, an increase of "virtual roll" means preloading dehydration is more stable, effectively prevent mud run phenomenon. ※ advanced filter flushing: belt wash system uses a specially designed filter clean mud, this technology can greatly reduce the amount of clean water. Can use the secondary settling tank effluent to do the washing water, completely changed the status of the use of water to wash filter high net cost, thereby achieving the purpose of environmental protection. ※ reliable operation performance: Correction of the machine connected to the cylinder valve using electromagnetic induction, the nearest control, fast response, from both sides of the filter with correction, rapid reset, the operation of the whole system of low frequency, low amplitude correction. Electronic control system with a sound chain protection devices to ensure the safety and reliability of machine operation, effectively prevents the damage caused to the machine malfunction. ※ PLC control design: The machine can be based on high-end users demand, PLC control design, the principle is based on the speed of the host automatically adjust the amount of sludge into the mud, the dosage, the productivity and dehydration rate can achieve the best state, reaches unattended. ※ application of mature technologies: a different selection of different filter sludge with different flocculants, different auxiliary equipment in order to achieve the best effect of dehydration. Structural features the use of a belt thickener and the belt filter press are combined continuous concentration used in a variety of different properties of the sludge dewatering, resulting in high solids cake rate. In the concentrated sludge solids segment increased from about 2% more than for the filter press sludge is concentrated to 5% and then dewatered in filter press section to more than 20% solids. Sludge dewatering machine comprises a stainless steel frame, gravity dewatering section, press section, mud rake, drives, belt filter cleaning device, filter belt tensioners, belt tracking and correction system filter, filtrate collection plate and drain pan, internal wiring and piping, etc., all using corrosion and wear-resistant materials to ensure stable operation of the device for a long time. Sludge dewatering machine has perfect automatic control and protection functions, once the inadequate amount of sludge, polymer missing, with a deviation filter, wash low water pressure, air pressure is too low, the external signal command shutdown and alarm etc. . Applications in the domestic environmental protection projects are widely used and has been put into mass production of the series with standardized dewatering machine products.
