Screw press sludge dewatering machine working principle
1. Sludge concentration: When the spiral drive shaft rotation, located in the drive shaft outside the multi-solid laminated stack relative movement, under the action of gravity, the water from the relative movement of the laminated gap filter to achieve rapid concentration.
2. Sludge dewatering: the concentration of sludge along with the rotation of the screw shaft continue to move forward; along the direction of the export of the cake, the screw shaft pitch gradually smaller, ring and ring between the gap is gradually smaller, the spiral cavity volume The pressure in the sludge is squeezed and discharged, and the solid content of the cake is continuously increased, and finally the sludge is finally realized. Continuous dehydration.
3. Self-cleaning: with the function of self-cleaning process, as a result, the clogging any troble while separating the water from the sludge easily. In addition, there is no need to add large quality of flushing water and bearing of internal recycle.
After the concentration of the sludge in the concentration of concentrated, was transported to the dehydration department, in the process of progress with the filter and pitch gradually become smaller, and the back pressure plate under the blocking effect, resulting in a great internal pressure, volume shrink , To achieve the purpose of full dehydration.
Screw press dewatering machine advantages
