Full Automatic Screw Type Sludge Thickener for Sludge Drying Process

BOEEP full automatic screw type sludge thickener treats the sludge of concentration 2500mg/L-20000mg/L and is for the next sludge dewatering and drying process.

Quantity:
  • MYDN301
  • BOEEP
  • MYDN

Product Description

Compared with the traditional volute screw press dewatering machine, screw sludge thickener is also advanced in the low operating & maintenance cost, dewatering performance, smell protection, low noise, automatic control, etc. The sludge from the secondary sedimentation tank can be condensed rapidly and continuously, and the sludge concentration can be adjusted between 90% and 96% stably after being condensed and separated. The device has many advantages such as no need concentrated tank, small footprint, less cost. Further more, it can effectively reduce the release of the odor & phosphorus caused by sludge concentrated tank, simplify the following treatment process, greatly increase the capacity of sludge dewatering and deep dehydration equipment.

Working Principle

Screw sludge thickener mainly consists of concentrating body, driving device, filtered water tank, mixing system and frame, etc. During operating, the sludge is pumped into the mixing tank by sludge pump, meanwhile, dosing pump feeds the mixing tank with prepared polymer quantificationlly. The sludge is mixed completely with the polymer by the stirring of motor in the mixing system, then alumen ustum will be produced. When the liquid reach the level of liquid level sensor, the screw body will get into operation, in which the sludge is being pressed. The thickened sludge will be discharged at the outlet gradually and the filtered water will come out between the fixed ring and moving ring at the same time. 

All in all, screw thickener adopt the principle of screw extruding to thicken the sludge through the high pressure generated by the screw distance changes and small gap between the mobile ring & fixed ring.


Technical Feature

  • Large sludge concentration range, applied water content of sludge: 98%-99.8%

  • The water content after thickened is 90%-96%, which can be adjusted stability

  • High concentration efficiency, small footprint

  • No need filter cloth, high pressure back water rinsing, self-cleaning, clog free

  • Low rotating speed, low noise, low power consumption, compact design

  • Enclosed working, odor emission is controled

  • Less wearing parts, easy to operate & maintain

  • Fully-automatic control, low labor need
