The curved screen is used for white water recovery, pulp thickening, waste paper deinking, etc. in the solid-liquid separation system of the paper industry. The curved sieve is the pulp that is delivered under a certain pressure and first enters the pure pulp distribution plate through the top pulp inlet of the curved sieve, where the pulp is accelerated and then enters the circular arc-shaped filter area tangentially, in this area , The slurry is dehydrated repeatedly by the centrifugal force, and then enters the slurry outlet under the action of gravity and is discharged out of the equipment, and the filtered wastewater is discharged through the wastewater outlet. It has the advantages of simple structure, small footprint, large processing capacity, and almost no power consumption.
Gravity cylinder thickener is suitable for dehydration concentration and washing of wood pulp, cotton pulp, rice-wheat straw pulp, and waste paper pulp. Compared with other existing pulp thickening equipment, it has the advantages of simple equipment structure, convenient installation and maintenance, high production capacity, pulp Wide adaptability and other advantages, it is widely used in the pulp and paper industry.
