1.Solid-liquid screw filter sludge dewatering machine principle.
Solid-liquid screw filter sludge dewatering machine organically combines screw conveying, filtration and concentration technology and screw pressing technology, the screw shaft in the main body has both transmission, conveying and extrusion functions, and the peristaltic screen outside the main body has self-cleaning function; Solid-liquid screw filter sludge dewatering machine When the filter sludge dewatering machine is running, the screw shaft rotates at low speed to drive the peristaltic sieve to form creep, the filtrate in the slurry is discharged quickly through the gap between the peristaltic sieve, while the solid-phase particles are pushed by the screw shaft to the discharge port, and the internal pressure between the solid-phase particles is enhanced through the two-way contraction of the conveying filter cavity, and the sludge cake is further dewatered and discharged.
2. Product advantages.
Based on the simple mechanical design, Solid-liquid screw filter sludge dewatering machine has the following major features.
1) Small and compact, energy-saving: the mechanical extrusion dewatering by screw and screw reducer is designed to be light and compact; the machine runs at low speed and consumes low energy, the unit power consumption is only 0.1kwh/kgds.
2) Wide range of applicable sludge concentration and small land area: It can directly treat low concentration sludge without setting up sludge thickening tank, thus saving the land area of sludge treatment system.
3)No clogging, easy treatment of oily sludge: There is no screen in the equipment, so there is no problem of clogging the screen, etc., and it can continuously dewater oily sludge.
4) No secondary pollution and good operating environment: It can directly treat unconcentrated sludge without odor; low-speed operation without noise; its peristaltic screen has self-cleaning function, no secondary water pollution and good operating environment.
5) Simple operation and management: safe and simple operation, combined with fully automatic dosing system, 24-hour unattended operation can be realized.
