Belt filter press - sludge filter press - belt sludge dehydrator - high pressure deep dehydration

Purpose and introduction

The belt filter press is an efficient dehydration equipment which dehydrates the concentrated sludge and forms the mud cake.Features: automatic control operation, continuous production, stepless speed regulation, suitable for a variety of sludge.It is suitable for sludge dewatering in water supply and drainage, papermaking, casting, leather, textile, chemical, food and other industries.

The working principle of

The sludge and the flocculant are fully mixed into the gravity dehydration zone of the belt filter press.Relying on the gravity of the sludge itself to remove a large amount of water, the gravity zone is equipped with a mud distribution device, sludge can be distributed on the filter belt, then into the upper and lower mesh belt wedge-shaped press section for pre-compression dehydration, free water finally into the press zone, the formation of mud cake.

advantages

1, automatic control, continuous

2. Low energy consumption and long service life;

3. High dehydration efficiency, high solids content of mud cake;

4. Easy to manage and maintain;

5, low noise, less chemical agents;

6, economic and reliable, wide application range.

performance

Scientific design and reasonable layout, to press the filter with high efficiency dehydration performance.The main dewatering roller is a perforated design, which not only increases the treatment capacity, but also enables the sludge to be dehydrated simultaneously on both sides. The two sides of the filter belt can be dehydrated quickly during the process of dewatering, which shortens the dehydration time.The reduced pressure roll arrangement at the back and the change of the contact Angle of the filter belt ensure the optimal combination of pressure and shear force, thus greatly improving the cement content and dehydration efficiency of the mud cake.

The characteristics of

The tension of the filter belt is realized by the inflatable cylinder, so that the entire filter belt maintains a constant tension.At the same time will not cause the change of tension due to the change of feed quantity, convenient operation and management.The filter press is equipped with an air pressure control system that automatically detects the position of the filter belt on the press roll and automatically corrects the deviation. The filter press with wide filter belt is also equipped with an automatic sludge feeding device to ensure the sludge enters the filter belt evenly.Thus improve the filtration efficiency and prolong the filter life.

structure

The belt filter press has two filter belts and an extended gravity dehydration zone before the normal pressure dehydration zone. This unique structure not only improves the dehydration efficiency and reduces chemical agents, but also greatly reduces energy consumption.

Application:

Belt type filter press is widely used in city life sewage, the textile printing and dyeing, electroplating, papermaking, leather, brewing, product processing, coal washing, petrochemical, chemical, metallurgical, pharmaceutical, ceramics, cement plant sludge, the mine sludge, the chemical fiber sludge, the refinery sludge, the steel plant sludge, the carbide slag, the electronic sewage, circuit board factory, the brewery sludge, slag slag kaolin, starch, alcohol, textile industries such as active sludge sewage treatment sludge dewatering processing.
