In a known device of this type, a floating body 29 (ball or flap ) of the tangential inlet is pressed in the upper region of the side 50 against the seat on the inlet funnel 8. The wall of the inlet funnel, which is on the top through further wastewater, now passes through the one ring-shaped rake, through the cylindrical wall 16 of the inlet funnel 8 located after the inlet funnel is closed by the flow channels 18 between the ribs 17 floating body, the wastewater into the collector - An overflow rake 15 overflows into the collecting container 1 holder. In this known execution 55 and fills this up to the intended cut-in height, shape of the inlet funnel, there is a risk that the inner edges 20 of the ribs 17 are located between the individual bars of the overflow rake in alignment with the cylindrical inner wall of the overflow rake for a longer period of time Between the inlet funnel 8, so that the flow of the tan space through the floating potential flowing sewage in the sewage does not have any substances on the ribs that experience breakage or stagnation when the sewage passes through. When the single rule sticks are filled, they accumulate and become clogged and so gradually run into a funnel8, the wastewater can also lead to a blockage. an annular gap 25, which by the inward

The invention is therefore the task. based on an annular boundary wall 24 protrude into the the overflow rake of the inlet funnel is to be arranged - the open top side of the inlet funnel 8 is formed, NEN and train that a blockage overflow into the collecting container 1 at 65. The one in the longer one Operating time is avoided. water-containing bulk materials initially remain

According to the invention, this task is thereby achieved in the inlet funnel 8. If the switch-on level is

switched on automatically. The mechanically pre-cleaned wastewater located in the collecting tank 1 is now by opening the flap through the rinsing jet orifice 6 into the rinsing container 5 and finally it is conveyed through the pressure line into the sewer. In doing so, everyone in the rinsing container 5 is adored Bulky materials carried away by the powerful, unbroken flushing jet 6 α. Since "the pressure pipe ass! U3 4 begins directly or in the immediate vicinity of a higher connecting flange 7, can also no floating matter remains in the washing container 5 during the conveying process. the Float29 (ball or flap) closes the bobbin case during the entire conveying process 5 against the inlet funnel 8. After the pump is switched off, the float 29 sinks downward. The bulky substances that have accumulated in the inlet funnel 8 now reach the lower-lying rinsing container 5. With further sewage inflow, the process described above is repeated.

If the inlet funnel 8 ίο is to be made higher in larger systems, the overflow rake 15 can consist of two rakes 21 arranged one above the other (Fi ti. Y> .
