How much do you know about the dehydration principle of stacking screws?

Domestic sewage mainly refers to various detergents, sewage and wastes used in urban life, and most of them are non-toxic inorganic salts. Domestic sewage contains many nitrogen, phosphorus, sulfur and pathogenic bacteria, which is one of the main sources of pollution in water. Stacking machines can help solve this problem. The stacking screw body of the dehydrator is a filter device formed by a fixing ring and a swimming ring stacked on each other, and a screw shaft is formed therein. The front part is a concentrated part, the rear part is a dewatering part, a filter joint formed between the fixing ring and the swimming ring, and The pitch of the screw shaft gradually decreases from the concentrating portion to the dehydrating portion. The rotation of the screw shaft pushes the sludge from the enrichment section to the dewatering section, and also continuously drives the swimming ring to clean the filter joint to prevent clogging.

The stacking screw machine is the abbreviation of the stacking screw sludge dewatering machine. It is a water treatment system widely used in municipal sewage treatment engineering and petrochemical, light industry, chemical fiber, papermaking, pharmaceutical, leather and other industrial occupations. After the actual operation, it is indicated that the dewatering of the stacked screw sludge can create considerable economic and social benefits for the customer. Perhaps you still find it hard to imagine, but you have to say that the stacking screw machine has made a lot of benefits for the environment. Do you know the working principle of the stacking screw machine? Listen to me gradually.

Dehydration principle of stacking screw

1. Concentration: When the screw pushes the shaft to roll, the multiple solid laminates located on the periphery of the push shaft move relative to each other. Under the action of gravity, water is filtered out from the relatively moving lamination gap to complete rapid concentration.

2. Dehydration: The concentrated sludge moves forward with the spiral shaft rolling; along the exit direction of the mud cake, the pitch of the spiral shaft gradually becomes smaller, the gap between the ring and the ring gradually becomes smaller, and the volume of the spiral cavity is continuously reduced. Shrinkage; under the action of the back pressure plate at the outlet, the internal pressure is gradually enhanced. Under the continuous operation of the screw push shaft, the water in the sludge is kneaded and discharged, and the solid content of the filter cake is continuously increased. Continuous dehydration.

3. Self-cleaning: The rotation of the screw shaft pushes the swimming ring to roll continuously. The equipment completes the continuous self-cleaning process by the movement between the fixed ring and the swimming ring, and then wonderfully avoids the clogging problem that is common in the traditional dewatering machine.
