Eco-friendly Solid-Liquid Separation Spiral Screw Sludge Dewatering Machine QXDL-301

The main body of the spiral screw machine is composed of stationary rings and movable rings stacked into a cylindrical shape, with a spiral shaft running through it to form a filtering device. Because the inner diameter of the movable ring is smaller than the outer diameter of the spiral shaft, the rotation of the spiral shaft can drive the movable ring to perform circular motion, preventing blockages. The gap between the stationary ring and the movable ring gradually narrows along the direction of the mud cake outlet, from the thickening to the dewatering section. After the sludge is thickened by gravity in the thickening section, it is gradually transported to the dewatering section, where forced dewatering is achieved under the internal pressure generated by the back pressure plate at the discharge outlet.

Advantages of the spiral screw:

1. Proficient in handling oily sludge: Compared to traditional sludge dewatering machines, the self-cleaning structure of the spiral screw is less likely to cause filter gap blockages, and it can easily handle oily sludge.

2. Compact design, space-saving: Compared to traditional sludge dewatering machines, the dewatering body, flocculation mixing tank, and electrical control cabinet of the spiral screw sludge dewatering machine adopts a three-in-one design, which is convenient for installation, occupies a small volume, and is highly compatible with ancillary supporting equipment, facilitating the replacement of existing equipment.

3. Simple operation and maintenance: It can be fully automatic and unattended for 24 hours through various sensing devices, and at the same time, there are few daily maintenance items, and maintenance work is simple.

4. Energy-saving: As the core component of the spiral screw, the rotation speed of the spiral shaft is 0-5 revolutions per minute. Due to the low-speed rotation, the electricity consumption is deficient. Under the same treatment capacity, the electricity consumption of the spiral screw is only 1/20 of that of the centrifugal dewatering machine.

5. Water-saving: The self-cleaning structure of the spiral screw body that prevents filter gap blockage can save a large amount of water for cleaning. Under the same treatment capacity, the water consumption of the spiral screw is only 1/115 of that of the belt dewatering machine.

6. Wide application range: Suitable for various industries such as municipal, tap water, pharmaceuticals, food, beverages, animal husbandry, chemical, machinery manufacturing, metal processing, petrochemical, and printing and dyeing.

7. Low noise, low vibration: The spiral shaft of the spiral screw body rotates at low speed, with almost no noise and vibration, ensuring a comfortable and quiet working environment.
