Master the choice and working principle of belt filter

Although the scope of the belt filter press is limited, the filter is indeed a common equipment for sewage treatment. Today, Xiaobian will introduce you to the selection and working principle of the belt filter.

The belt filter is mainly composed of a filter belt, a roller cylinder, a filter belt tensioning system, a filter belt deflection system, a filter belt washing system and a filter belt drive system. The following aspects should be considered when selecting a belt filter press:

Filter belt:

The filter belt is required to have high tensile strength, tortuosity, acid and alkali resistance and high temperature resistance. The specific properties of the sludge should also be considered. It is recommended to choose a suitable woven texture to give the filter belt good gas permeability and interception of sludge particles.

Belt speed control:

Different performance sludges have different requirements on belt speed. That is to say, for any particular sludge, there is a good range of belt speed control. Within this range, the dewatering system can ensure a certain processing capacity and obtain high quality mud cake.

The belt filter is less affected by fluctuations in sludge load, and has the characteristics of low moisture content and stable operation, low energy consumption, and low requirements for the quality of the operating personnel.

Relatively speaking, the operation of the belt filter is a little simpler. I hope that I can help you through the introduction of the filter selection and working principle introduced above.
