• the housing elements is provided per ⁇ wells an inflow and a flow channel, said inflow and a flow channel located behind each other, in particular in alignment, and forming in succession with in each case one of the apertures in the rotary filtration system a continuous flow channel. If the current flow through the sieve is too dirty, the sieve wheel will turn an angle turned so that the next following sieve is pivoted into the flow channel. As the screen wheel rotates, whether stepwise or continuously, the soiled screen is placed in the area of a screen change port in the housing where the screen is freely accessible. There, the sieve can be removed and replaced.
• the dirt separator described in EP 379 966 A2 also discloses a backwashing function in order to be able to detach deposits from the dirty side of the sieve and thus to be able to clean the sieve without complete removal from the sieve opening.
• the melt is diverted from the flow channel at the back of the housing and returned from the clean ⁇ sieve side through the screen.
• Adhesive particles adhering to the screen element can thus be released by the dynamic pressure applied from the rear and flushed out of the housing.
• the projectisseff ⁇ tion which establishes the connection to the outside of the housing, can be closed with a movable slide.
• a disadvantage of the known generic dirt separator is that in each case only a few Siebstellen in function and are within a continuous F grease ⁇ nals, while distributed over the screen at ⁇ their Siebstellen, which are still filled with the medium, remain idle, whereby the throughput is limited to the flow channel cross section of the currently in production screen position.
• screening elements are provided which are significantly larger than the opening cross-section of the inlet and outlet channels, so that funnel-like transitions must be provided.
• the fluid flow in the outer regions of a flow channel has to travel longer distances than in the center. The result is an inhomogeneous fluid retention time spectrum in the area of the screen.
