The use of screw sludge dewatering machine Apr 08, 2018

Screw sludge dewatering machine is unique in that it uses spiral extrusion to work continuously. This working method is very suitable for the separation of phase-containing particles 0.5-1.0mm, the solid content in the feed liquid is large, and the water content is required after separation. Low-level materials, such as waste from man-made board mills and cattle, pigs, chickens, etc. in livestock farms, are treated with screw-type sludge dewatering machines.

 

The built-in structure of the screw-type sludge dewatering machine is also not complicated. The section of the spiral blade is perpendicular to the axis, and the dimension of the connecting section of its movable nozzle and deforming nozzle is the same as that of the rectangular mouth of the deforming nozzle. The upper part is the same. A movable platen, the bottom of which is a rectangular cross-section groove, adjusts the force applied to the movable platen to adjust the preform pressure.

 

When the screw sludge dewatering machine treats the sludge, it can be pushed in the direction parallel to the axial force toward the deforming nozzle. When the sludge is pushed into the deformed mouth, the water is separated due to compression. In the screw sludge dewatering machine, the role of the deformation nozzle is to confine the annular section of the material to a rectangular section.

 

Usually, there should be a spiral blade with a length of 1/4 pitch between the inlet of the screw sludge dewatering machine and the back wall of the cylinder, and the clearance between the screw and the cylinder is generally not more than 2~3mm, in order to avoid the material meeting. The backflow occurs, but also in order to effectively improve the extrusion efficiency.

 

The sewage treated by the screw sludge dewatering machine can generate biogas after anaerobic treatment, and can be used as fuel, generate electricity or can be used as foliar fertilizer after pressure filtration, and can also be pumped to the greenhouse as a nutrient of the plant and can be changed. Waste is treasure, so the screw sludge dewatering machine has played a positive role in protecting the environment and creating economic benefits.
