Sludge is the solid sedimentation material produced by water and wastewater treatment processes. The water content in the sludge is high, so what kind of conveying equipment should I choose? Today, Dahan Machinery recommends Dahan’s dedicated sludge treatment——Shaftless Screw Conveyor.
Inclined sludge transport
Sludge packing
"Dahan" Shaftless Screw Conveyor is specially designed to solve the problem of sludge winding for you, and at the same time reduce the problem of sludge damage during the conveying process, saving manpower and material resources while saving energy.
Shaftless Screw Conveyor for Sludge is a device used to transport sludge, waste and solid particles. When choosing a Shaftless Screw Conveyor, factors such as the water content of the sludge, the conveying distance and the conveying volume need to be considered. The following is the model, length and conveying capacity of the shaftless screw conveyor used for sludge with different water content:
1. For sludge with a water content of 20%, use a WLS160 shaftless screw conveyor with a length of 10 meters and a conveying capacity of 1.2 cubic meters per hour.
2. For sludge with a water content of 40%, use a WLS200 shaftless screw conveyor with a length of 15 meters and a conveying capacity of 1.5 cubic meters per hour.
3. For sludge with a water content of 60%, use a WLS250 shaftless screw conveyor with a length of 20 meters and a conveying capacity of 2.0 cubic meters per hour.
Conveying sedimentation tank sludge: angle 40 degrees, length 8 meters, 20 cubic meters per hour;
Conveying sludge: 4-5 tons per hour, 10.04 meters high, 20 meters long, 70° angle, and a shaftless screw conveyor with a large inclination of 325mm;
Oily sludge is stored in the conveying tank: the moisture content is 60%-80%, and the sludge is stored in the tank, and the shaftless screw conveyor with a large inclination angle;
Sludge conveying from sewage plant: inclination angle 30 degrees, conveying length 25m, conveying 3 tons per hour;
The specific gravity of the dried sludge after conveying is 0.6-0.8g/cubic centimeter, the dump truck feeds 4 liters, and the vibrating feeder discharges the material to the shaftless screw conveyor, with a conveying capacity of 5 tons per hour;
304 stainless steel shaftless screw conveyor, sludge 3 meters (its drying equipment is high), feeding 300 kg per hour, silo 300-500 kg;
Sludge conveying from water plants: The height of the inlet and outlet is 4.0 meters, 5m³ per hour, and a vertical shaftless screw conveyor is required;
According to the nature of the sludge, Dahan recommends that you choose the Shaftless Screw Conveyor, and use the advantages of the Shaftless Screw Conveyor's anti-winding and anti-stickiness to solve the problem of difficult transport of sludge. Compared with traditional conveyors, Shaftless Screw Conveyor can convey granular and powdery materials, wet and pasty materials, semi-fluid and viscous materials, easily entangled and clogged materials, and materials with special hygienic requirements.
Shaftless Screw Conveyor has compact structure, saves space, is easy to operate, economical and durable, and has good performance. The use of a fully enclosed and easy-to-clean spiral surface can ensure that the conveyed materials will not be polluted and will not leak conveyed materials. It can reduce the damage problem of sludge during transportation.
The conveying capacity of the Shaftless Screw Conveyor is 1.5 times that of the shaft screw conveyor with the same diameter. The conveying distance is long, and the conveying length of a single machine can reach 60~70m. Large torque, low energy consumption, and no blockage of the discharge port. Its automated operation also greatly saves manpower and material resources.
