Self-Cleaning Filter

Multi-function self-cleaning filter is researched and developed based on auto filter. It's suitable for harsh conditions where there are various types juice of impurities. The design is multi-functional and structured. The cleaning component uses sucking or scraper. It's able to clean impurities adsorbed on the filter element surface very effectively. When the filter pressure difference between the inside and outside of the filter mesh reaches the default values or the regular cleaning. Products Description Self-cleaning backflushing clarified filter, also for highly viscous media and high temperatures.

Fully automatic backflushing filters are primarily used for the filtration of clear juice, Raw melt, spray water or River water and work almost wear-free. Due to its simple backflushing system, this self-cleaning filter can also be used for highly viscous media and in high temperature areas. The cleaning process is possible without interruption of filtration. To remove impurities from clarified cane juice such as bagacillo, cellular materials, and residual flocs, to replace current DSM screen or cloth screening methods. The advantages of these new backflush technologies are: - Virtually no power consumption (except for automatic valves) - Self cleaning system - Virtually no recycle of juice with bagacillo – typically 0.001% - No heat loss – totally enclosed insulated system - Virtually Maintenance free

Working Principle:

The waste water enter into the filter, In filter process, the fine screen surface gradually accumulates the impurities from the water, then form the filter impurity layer. Because the impurities accumulate in inside of the fine screen, then forming a pressure difference inside and outside of the fine screen.

When the differential pressure system reaches the preset value, the system of water supply is not interrupted, open backwash valve or drain valve, the waste water outlet from the drain valve. While the pressure go down in the hydraulic motor chamber and dirt collector, then the suction nozzle of suction assembly begin suction process: there is a very strong backwash water flow to the outside, the suction nozzle produce a suction power plus the flow power through the hydraulic motor. Because the hydraulic piston pressure go down, lead the dirt collector rotate around the axis of rotation to move, so perfectly clean the inner surface of fine screen. This type of filter is simultaneously provided with a timing controller, which can regular blowdown in certain time.

Product Features:

• Compact body, firm and reliable structure
• Small backwash water consumption, low water pressure demand
• High filtration precision, suitable for all kinds of water quality
• Small backwash pressure reduction, no effect on normal water supply
