Problems solved by technology

[0004] While the filter is ideal for removing larger and heavier impurities from the liquid, when there are very fine or light impurities, there are often problems in removing floats from the sieve device because the discharge The device does not capture these flotsam well, or the flotsam refloats the area, making it more difficult to discharge

Embodiment Construction

[0054] figure 1 Shown is a part of a waterway 1 in which sewage 2 with a generally varying water level 3 is polluted by floating matter flowing in the direction of the arrow. The sieve-shaped device installed here is built in the channel 1 with its axis inclined, the sieve-shaped part preferably extending to the bottom of the channel 1, wherein a corresponding seal is made between the channel 1 and the device (not shown), so that dirty sewage 2 cannot pass through the device unfiltered.

[0055] The device itself includes a sieve-shaped component, which is a filter frame 4 in the shape of a cylinder liner (in figure 1 Middle is a partial sectional view, so that one can see its interior), the filter area of ​​the filter frame can consist of a perforated or grooved metal sheet, for example a non-woven mesh preferably supported by a carrier basket.

[0056] At the inlet end, the filter frame 4 has an open front end 5 through which the dirty sewage 2 can flow into the interior o...

Abstract

The invention refers to a device for removing floating material from a liquid, especially from sewage (2), with at least one sieve element shaped like a filter basket (4), for example, that in a front side has an inlet opening through which liquid can flow into the interior of the sieve element, and is equipped with a drive so the sieve element can rotate around a rotation axis. The invention suggests arranging a collection device (17) within the sieve element for collecting the liquid and/or floating material, in which case the collection device (17) is attached to a pumping-out device (20) for the liquid and/or the floating material. Another object of the invention is a process for removing floating material from a liquid, especially from sewage (2), in which case a sieve device is used that contains at least one sieve element that can be shaped like a filter basket (4), for example, and is equipped with a drive so it can rotate around a rotating axis. The process is characterized by the fact that liquid and/or floating material is collected with the help of a collection device (17) arranged within the sieve element for subsequent withdrawal from the collecting device (17) with a pumping-out device (20).

Description

technical field [0001] The invention relates to a device for removing floating matter from liquids, especially sewage, which device has at least one sieve-shaped part shaped like a filter frame, for example, with an inlet in the front region of the sieve-shaped part through which liquid can flow into the The inside of the sieve-shaped part is also provided with a drive, so that the sieve-shaped part can be rotated around the rotation axis. Furthermore, a method for removing floating matter from liquids, especially sewage, is proposed, using a sieve-shaped device having at least one sieve-shaped part, for example in the form of a filter frame, and equipped with a drive so that the sieve Shaped parts can rotate about the axis of rotation. Background technique [0002] A device of the above-mentioned type is known from DE 34 20 157 C1. The device has a screen grate shaped like a cylinder liner, said screen grate is placed in the waterway obliquely to its axis, hydraulically o...
