Decanter Sludge Dewatering Belt Press with Gravity Thickener for Municipal Sewage

BOEEP sludge dewatering belt press machine utilizes gravity to concentrate first, then dehydrate by belt press. It is used for decanter sludge for municipal sewage treatment process.

Quantity:
  • DNY1.5
  • BOEEP
  • DNY

Product Introduction

BOEEP sludge dewatering belt press machine is mainly used for processing the sludge which is not concentrated in the thickening pool, such as A/O residual sludge or SBR residual sludge. It has two functions: concentrating and dewatering. Compared with Rotary Drum Thickening Belt Filter Press the structure is different, for the sludge is thickened by the gravity, which is used in the higher capacity.

Overall Structure

BOEEP sludge dewatering belt press machine runs smoothly and normally, no impact, vibration and abnormal sound, after all parts are checked to be qualified, the assembly can be executed. In order to adjust frame horizontal  conveniently , Frame is fixed on the foundation  with  anchor bolts,and equipping with adjusting device. 

The mud inlet, dosing, mixing, reaction are all realized in the dewatering system, and the pipeline operation of dehydration and mud cake output is proceeded under the laminar flow condition.

In order to keep the device operating stably and reliably, the design and manufacture of sludge dewatering belt press machine should adapt to the harsh working environment with the high temperature and 100% humidity.

Working Principle

1-The flocculated sludge is evenly sent to the gravity thickening area by the rake, where there is a long horizontal movement and a small angle of rise, and the sludge moves along with the filter belt. Under the gravity, the free water and the floc are separated, and most of the free water in the sludge is removed. The thickened sludge is basically out of fluidity and scraped through the scraper to the filter press section.

2-When the thickened sludge enters the wedge-shaped dewatering zone, it is further leveled in the wedge-shaped zone, and is subjected to mild extrusion. The wedge-shaped space formed by the upper and lower filter belts is from large to small, and finally the two filter belts are closed, so that the squeezing force of the filter slurry sandwiched in the middle of the filter belt is gradually increased, and the filtered water is continuously discharged. At this time, the slurry has become sludge cake.

Technical Advantage

  • The filter belt adopts pneumatic tension, convenient operation, low investment cost.

  • Automatic pneumatic rectification is used to rectify the filter belt in real time by induction switch, which makes the equipment stable and reliable.

  • Pipeline filters are installed on the equipment, which can effectively use the effluent from the secondary sedimentation tank as cleaning water, to save tap water and reduce operation costs.


Application

BOEEP sludge dewatering belt press machine is a continuous operation and efficient solid-liquid separation equipment. It is suitable for solid liquid separation in municipal, chemical, metallurgical, mining, food and papermaking industries, and so on. Especially in the municipal sewage treatment plant, the process is simple, the process applicability is strong, the operation is continuous, and the treatment efficiency is high.
