Outer-Scraper Type Self-cleaning Filter
The working principle of outer-scraper type self-cleaning filter is that liquid enters through the water inlet and flows up to the bottom, and then flows out through the filter elements' surface. When the impurities on the filter element's surface accumulate to a certain amount, the scraper driven by electric machinery and equipped with correctors will rotate near the filter elements to scrap off the impurities. Then the impurities will be collected in the collection chamber. When it is managed to a certain amount, the automatic drain valve opens and drains out the liquid containing a high impurities concentration. The fluid after filtration would be recycled or discharged.
Major Components:
- Drive motor, differential pressure controller, differential switches, indicator light, valves; alarms, timers, and display screens as an option.
- Circuit breaker for overload protection.
- PLC-based control system for control the time of scraper and sewage discharge.
- Differential pressure controller protection and monitoring system.
- Drain valve driving: electric/pneumatic.
- Pre-installed and tested for easy installation.
Features:
- With the leading outer-scraper filter type, this filter extends the filtration time under the same filter area and reduces the waste of material;
- Adaptive adjustment of miscellaneous equipment ensures that the filter will not be affected by the wear when working for a long time;
- Filter elements are made by mold. The roundness deviation does not exceed 0.5mm to ensure the scraper will be fit entirely to the details;
- Humanization design: the drain valve would open just when the impurity is collected to a certain amount after cleaning several times to reduce material waste.
