The sand washing sewage treatment equipment has a large processing capacity, high efficiency, continuous 24-hour work, fully automatic operation, small footprint and convenient transportation, and manufacturers supply prices.
Working principle of sand washing sewage treatment equipment:
Sludge and flocculant enter the centrifuge from the feeding tube at the same time, the solids in the rotating drum are thrown to the drum wall, the separation liquid is squeezed to the center of the drum, and the solids settled on the drum wall are pushed by the screw It is pushed out of the slag outlet and discharged out of the machine. The separation liquid is discharged out of the machine through the overflow hole of the large end of the drum. The differential is a device that ensures the stability of the differential speed. Stepless adjustment of differential speed can adapt to changes in flow and concentration, ensuring a good and stable separation effect.
High dryness—dross drying: Our company's decanter centrifuge uses a unique large cone angle patented technology: the cone angle strongly presses the solid phase filter cake to squeeze out the water in the solid phase; the second cone angle dehydrates the solid phase, Drain the water on the surface of the solid phase; the third cone angle buffers the solid phase and smoothly discharges it, avoiding blockage of the material and avoiding the trouble of starting water injection and shutting down and flushing. At the same time, the liquid phase becomes clearer due to the lengthening of the settlement zone. The introduction of this model brings new breakthroughs in sludge dehydration, with cleaner liquid phase, drier solid phase, less flocculant, and larger processing capacity. In particular, the high-dryness performance of slag discharge has very significant advantages for the harmless treatment of sludge. For the food processing industry, in protein processing, the yield of protein separation can be greatly improved. In the separation of distiller's grains, due to the low moisture content of the dross residue, the cost of subsequent processes can be greatly saved.
