The automatic backwash filter is an industrial automatic filter that can provide a variety of comprehensive purposes to ensure the purity and reliability of the filtered liquid. It is suitable for most standard applications of water filtration, in terms of treatment capacity, reliability, and can continue to maintain good operation even under harsh operating conditions.
The automatic backwash filter is an industrial automatic filter that can provide a variety of comprehensive purposes to ensure the purity and reliability of the filtered liquid. It is suitable for most standard applications of water filtration, in terms of treatment capacity, reliability, and can continue to maintain good operation even under harsh operating conditions.
The water enters from the inlet, firstly passes through the coarse filter to filter out larger particles of impurities, and then reaches the fine filter. During the filtration process, the fine filter gradually accumulates dirt and impurities in the water to form a filter impurity layer. Since the impurity layer accumulates on the inner side of the fine filter, a pressure difference is formed between the inner and outer sides of the fine filter.
When the pressure difference of the automatic backwash filter reaches the preset value, the automatic cleaning process will start. During this time, the supply of clean water will continue to flow, the cleaning valve will be opened, and the water pressure in the cleaning chamber and the suction device will drop significantly. Due to the pressure difference of the sewage pipe, a suction force is generated between the sewage suction pipe and the cleaning chamber through the suction nozzle, forming a sewage suction process. At the same time, the electric motor drives the sewage suction pipe to make a spiral motion in the axial direction. The axial movement of the dust collector is combined with the rotational movement to clean the inner surface of the entire filter screen. The entire flushing process takes only tens of seconds. The drain valve closes at the end of the cleaning. The filter begins to prepare for the next flush cycle.
1. The design structure is simple.
2. The backwashing time is short, the flow rate and pressure loss are small.
3. The control system is intelligent (PLC, PAC) control, with a high degree of automation.
4. High-precision filtration, stable water quality.
5. Long service life.
6. Applicable to different raw water quality and water requirements.
7. Fewer wearing parts, no consumables, low operating cost, simple operation and management.
8. Automatic anti-cleaning flow continuously.
