Installation debugging and maintenance of condensed belt press-filter A. Scope of application： ZDNY Belt-style condensing press-filter is a solid-liquid separating machine combining condensation, pressing and filtering and can work continuously and high-efficiently. It is applicable to any kind of solid-liquid sedimentation and separation of suspend material widely in chemical industry, metallurgy, mining, food, paper making, urban water supply, draining and many other fields. This equipment features easy craft flow, good applicability, small area occupation, short sludge stay and high ifficiency, saving investment in sludge removing condensation machine and pond B. Features: 1. This equipment combines condensation, press and filering, reducting investment in pond. 2. This equipment features high automation, designed with pneumatic filtering belt deviation correcting device. 3. This equipment adopts condensation filtering water as flushing water, decreasing operation fee. 4. This equipment features easy craft flow, good applicability, reasonable structure, small area occupation, short sludge stay and high efficiency. C. Equipment structure: The ZDNY machine consists of machine frame, conveying device, gravity dewatering, prepressing dewatering, upper/lower filtering belts, cloth device, filtering device, press roller, guide roller, discharge device, auto protection device, pneumatic control cabinet and electrical control. Working theories: the sludge mixed with flocculated suspend material goes into gravity centrifugal dewatering system, and under gravity, squeezing and overturning, the sludge will lose most of the free water. The sludge that goes through predewatering, goes through cloth chute and spreads evenly between the two sealed belts and into the rift between the two belts to be pre-dewatered. It then passes through rollers in the form of “s” from the least diameter one to the biggest, squeezing and cutting the filtered cake correspondingly to dewater.
