working principle

[Filtering status]

The liquid flows in from the inlet, and the spring strip scraper closes to the outer surface of the filter element in a tangential manner. The liquid flows inward from the outer surface of the filter element through the filter screen, the impurities are trapped on the outer surface, and the liquid flows out from the outlet; as time goes by, The impurities gradually increase and the pressure difference rises. The filter element is cleaned according to the set pressure difference or regularly.

[Cleaning status]

The motor drives the scraper to perform a horizontal rotation to clean the filter element. When the scraper rotates, the impurities are scraped (peeled off) by the scraper and flow along the filter screen to the bottom of the filter, and the impurities are deposited in the dirt collection chamber. Each cleaning consists of several strokes. After the surface of the filter element is cleaned, the filtering capacity is restored. Normally filter during cleaning without interruption of flow.

[Sewage status]

After multiple cleaning cycles, impurities accumulate to a certain amount, and the drain valve is opened regularly to discharge the waste liquid containing high-concentration impurities. If necessary, it can also be recycled.
