Abstract: The present invention refers to a sieve device for separating and removing impurities (1) from sewage (2) with at least two endless drive elements running parallel to one another that can be driven with the help of a drive (3) in conveying direction (F), wherein the drive elements (4) are guided in each case over a lower redirecting area (5) and an upper redirecting area (6) along an orbit, wherein multiple sieve elements (8) extend, arranged adjacently to one another between the drive elements (4), and connected to the drive elements (4), wherein at least most of the sieve elements (8) have in each case a sieve surface (9) curved outward in a side view of the sieve device and wherein the sieve device, downstream from the upper redirecting area (6) in conveying direction (F), has a cleaning device (10) that the sieve elements (8) can pass through while they move along the orbit mentioned above in order to remove the impurities (1) held back by the sieve elements (8) of the sieve surfaces (9).

Abstract: A sieve device for insertion in a shaft has a connection for wastewater arriving in a supply device, which supply device is connected to a sieve surface of the sieve device for separating material to be separated from the wastewater. A worm conveyor transports the material to be separated out of the shaft. A fastening device is arranged in the shaft for the vertical fastening of the sieve device. The fastening device comprises a guide for the sieve device. An intersection is provided between the supply device and the sieve device. The guide positions the sieve device in front of the intersection when the sieve device is moved relative to the supply device into the shaft for purposes of mounting.

Abstract: A sieve device (1) for insertion in a shaft (2) comprises a connection for wastewater arriving in a supply device (3, 4), which supply device (3, 4) is connected to a sieve surface of the sieve device (1) for separating material to be separated from the wastewater, and comprises a worm conveyor device (25) that comprises a worm conveyor for transporting the material to be separated out of the shaft (2). A fastening device (1) is arranged in the shaft for the vertical fastening of the sieve device (1). The fastening device (10) comprises a guide (12) for the sieve device (1). An intersection is provided between the supply device (3, 4) and the sieve device (1). The guide (12) positions the sieve device (1) in front of the intersection when the sieve device (1) is moved relative to the supply device (3, 4) into the shaft (2) for purposes of mounting.
