Abstract
The invention relates to a device for cleaning the filter surface of a filter element, through which the liquid to be filtered flows, during a filtration operation using a pressurised cleaning fluid. According to an improvement of the invention, a distribution device is provided which delivers an essentially even pressure distribution of the cleaning fluid over the entire area of the filter surface to be cleaned.
Claims13
Arrangement comprising a filter element and a device for cleaning a substantially cylinder mantle-shaped filter surface (106) of a filter element (100), through which a fluid to be cleaned flows during filtration operation, by means of a pressurized cleaning fluid, wherein a distribution device (30) having a flow guiding surface for the cleaning fluid exiting from a pressure line is provided, with which a substantially uniform pressure distribution of the cleaning fluid in the area of the entire filter surface to be cleaned is promoted, wherein the flow guiding surface extends coaxially to the filter surface, is as a whole substantially truncated cone mantle-shaped, and extends, beginning at an opening (102) arranged at an axial end of the filter element, across 20 to 70% of the axial length (L) of the filter element (100).
