The main body of the stacked screw solid-liquid separator consists of multiple fixed rings and moving rings, with a spiral shaft passing through to form a filtering device. Driven by the rotation of the spiral shaft, the sludge continuously advances, while being influenced by gravity and a special laminated structure, gradually separating solid matter from liquid. After gravity concentration in the concentration section, the sludge is transported to the dewatering section. During the process of advancement, as the filter gap and pitch gradually decrease, as well as the blocking effect of the back pressure plate, the sludge is subjected to great pressure, and the volume continues to shrink, ultimately achieving the goal of full dewatering.
Stacked screw solid-liquid separators are widely used in fields such as sewage treatment, food industry, chemical industry, pharmaceutical industry, mining metallurgy, paper industry, etc. In terms of sewage treatment, it can be used for pre-treatment or deep treatment of urban domestic sewage and industrial wastewater; In food processing, it can be used for clarifying and filtering beverages such as fruit juice and alcohol, as well as treating wastewater from meat processing; In the chemical and pharmaceutical industries, it is suitable for the separation of solid-liquid mixtures after various chemical reactions and the separation of liquids containing drug residues generated during drug production processes; In addition, the stacked screw solid-liquid separator is widely used in mining, metallurgy, and papermaking industries.
