Accordingly, drum screen systems in different designs are state of the art, see the aforementioned prospectus documents.

The known systems have guided through the drum conveyors for the screenings or attached to the drum inner wall helical turns, which carries away the retained material in the direction of the drum end face.

The disadvantages of the known machines are:
By relative movements or scraping processes already screened substances are crushed and can thus escape through the sieve holes or gaps again. The problem here is that especially shredded microfibers and cellulose parts tend to chain again. An undesirable pigtail formation in the systems following the screen is often the result.

Especially in the field of wastewater treatment plants, there are often significant problems with so-called "pigtails". The "braid formations" have increased in recent years, which is due to the changed hygiene behavior of the population. Above all, microfibre cloths, solid cellulose cloths from the care sector and moist toilet paper papers are the cause of the "braid problem".

Another disadvantage of the known Siebtrommelanlagen with passages on both end faces is that for fluidic reasons, the fluid level in the drums can not be too high, which limits the throughput.

The object of the invention is therefore to improve a screen drum device of the type mentioned in such a way that it is simple in construction and yet has an improved screening performance, in particular with regard to throughput and / or avoidance of braid formation

This screenings falls into the Siebgutsammelwanne and flows out of the Siebgutwanne preferably in its own separation device, which separates the liquid from the liquid-solid mixture, or in the suction port of a pump. For example, by means of pump and pressure line, the solid-liquid mixture can be conveyed to a more remote screenings treatment plant, for example a sieve belt press, centrifuge, sludge tank, etc.

According to a further advantageous embodiment, the liquid-solids separation device can also have a separate Siebschnecke with integrated Siebgutpresse flanged directly on the outlet pipe of the Siebgutsammelwanne.

According to one embodiment, the screenings separating device is e.g. connected to the outlet pipe of the tub by means of a rotatable flange. Preferably, a helical or Schnecken Siebmaschine is connected to the rotatable flange. This machine preferably has a perforated screen or slot screen at the bottom. Preferably, the screen openings should be smaller than or equal to the screen openings of the screen drum. The sieve at the low point of the Siebmäntel Siebguttrenn- and -austragsvorrichtung is preferably cleaned by means of brushes, which are located on the flanks of the screw conveyor. Since the screen material is mechanically stressed by the brush cleaning and can escape in the comminuted state through the screen openings (and thus is a braid-forming material), the sequence of the screening zone is preferably reintroduced into the fine screen drum.

The filtrate of Siebguttrennvorrichtung is preferably re-screened and does not get directly into the downstream equipment components.

According to a preferred embodiment, the Siebguttrenn- and -austragsvorrichtung can be mounted vertically or in an inclined position due to the rotary flange on the discharge of the Siebgutsammelwanne. As a result, a variable discharge point of the material to be discharged is given. A simple adaptation to containers or conveyors is ensured.

In order to obtain enough liquid for a pumpable material, the baffles can also be designed as scoop pans
