  Stacked screw sludge dewatering machineUse a foaming device to dry the flocculant sol. Some polymer flocculants are usually dilute several times. The sludge is in accordance with the sludge transfer pump, and the infused flocculant is added to the flocculation mixing tank according to the dosing pump and the corresponding proportion of the Jinzhong stacked screw sludge dehydrator. The alum is fully mixed according to the mixer. flower. Today, Hangzhou Co., Ltd. will take you to understand the setting of the mixing device of the stacked screw sludge dewatering machine:

1. Concentration: When the spiral unfolding shaft is running, the multiple solid and active lamination pairs placed on the periphery of the unfolding shaft move. Under the action of gravity, water is filtered out of the moving lamination gap to achieve rapid concentration.

2. Dehydration: The thickened sludge continues to move forward with the rotation of the screw shaft; along the direction of the mud cake outlet, the pitch of the screw shaft weakens little by little, and the gap between the rings also weakens little by little. The volume of the spiral cavity of the middle stack screw sludge dehydrator continues to shrink; under the action of the back pressure plate at the outlet, the internal pressure rises little by little, and the water in the sludge is squeezed by the continuous rotation of the spiral unfolding shaft When discharged, the solid content of the filter cake continues to increase, achieving continuous dewatering of the sludge.

3. Maintenance: The rotation of the screw shaft of the Jinzhong stacked screw sludge dewatering machine unfolds the moving ring to continuously operate. The equipment relies on the movement between the fixed ring and the moving ring to achieve a continuous self-maintenance process, thus cleverly avoiding the general Difficulties in infarction that are common in dehydration machines.
