Self cleaning brush filter vessel by gravity filter down to 50 micron particle removal

Description:
The brush type self cleaning filter is mainly used in the fluid which contains more gravity impurities in liquid to be filterred. It's gravity filter.
Automatic self-cleaning filter is a kind of filter which is suitable for bad environment. It's with 3500 micron- 50 micron mesh and 8”-36”pipeline diameter for different using requirements. The cleaning process is started by a differential pressure switch which is monitoring the differential pressure of inlet and outlet, normally the pre-set value is 0.5bar (7psi).
Suitable for filters with DN25~DN900 pipeline to choose from. With advantages of continuously fluid flow, safety operation, simple maintenance, this kind of filter is widely used in all industries.

Work process:
When the differential pressure of inlet and outlet reaches the pre-set value, the filter will start the cleaning process. The whole self-cleaning process includes two steps: 1. Turn on the drain valve which is on the filter top cover. 2. Two stainless steel brushes inside the filter mesh start to rotate which are driven by motor. The impurities captured by filter mesh are brushed by steel brush and discharged from drain outlet. The whole cleaning process takes about 15-60 seconds. During this time, the filtration system doesn’t interrupt the water supply and the whole operation process is controlled by a control box.

Advantage:

• Uninterrupted water supply: the water consumption of cleaning is very few, which is less than 5% of the total flow. The cleaning time is about 2~15 seconds. When it is cleaning and discharging, water supply is uninterrupted.
• High filtering accuracy: filtering accuracy can reach up to 20μm and there are all kinds of accuracy of filtering screen can be chosen.
• Large filtering area: effective filtering area of standard screen is 7-40 times of inlet area.
• Reliable cleaning: a variety of control modes can be selected, such as manual, differential pressure, time, PLC control, etc.
• Simple and economical installation: varied structure forms, which are suitable for all kinds of site situation installation, without affecting the operating effect.
