Inclined Screen Solid Liquid Separator

Working Principle

Inclined Screen Solid-liquid Separator works continuously by means of spiral extrusion. It is suitable for materials with 0.3mm solid particles, large solid proportion in the feed liquid and low moisture content after separation. It is especially suitable for the dewatering and separation of pig manure (blister manure) with water content higher than 90% into liquid organic fertilizer and solid organic fertilizer. The solid-liquid separator divides the solid-liquid separation cylinder into centrifugal separation section and extrusion separation section, that is, the solid-liquid separation and solid-liquid separation of biogas residue are carried out through centrifugal separation and extrusion separation, the water content of biogas residue is greatly reduced, the drying time of biogas residue is reduced, the drying cost is reduced, and the time and cost are saved for users producing biogas fertilizer.

Advantages

• Compact structure with small floor space and easy installation. It supports standalone or parallel combined operation with independent running, effectively saving operating costs and resources.

• Low power consumption, high separation efficiency and large daily processing capacity.

• Wide application coverage. The screen cylinder gap ranges from 0.25-1mm, allowing customized screen hole selection for pig, cattle and other livestock farms based on manure characteristics.

• The inline screen structure adopts four-fulcrum support for the screen and double-end support for the spiral shaft, ensuring excellent operational stability.

• Equipped with a pressure regulating device to flexibly adjust the moisture content of solid discharge and processing capacity.

• Adopting vibrating screening and screw extrusion technology. Low secondary environmental pollution; the moisture content of separated solid manure is controlled at 30%-60%, facilitating storage and transportation.

• The separated liquid features a solid content of approximately 1.5%, effectively avoiding scaling and sedimentation.

• High automation of the overall system. Linked with septic tank liquid level monitoring, it realizes automatic start-stop of feed pumps, mixers and separators. Manual control is also optional to reduce labor input.

• System power configuration is adaptable to farm scale and layout, with matched cutting pump and mixer power of 5.5kw-8.5kw, delivering low overall energy consumption.

• Core wet parts and contact pipe fittings are made of 304 stainless steel, featuring outstanding corrosion resistance, stable performance and long service life.

• Self-cleaning operation without regular flushing required, simplifying daily operation, maintenance and management.
