Abstract: A device for separating and removing material to be sieved from flowing liquid includes a screen forming a sieve surface and fixed to a frame with grate bars arranged beside one another and separated from each other. At least one cleaning rake with numerous cleaning prongs can be in a conveying direction along the screen via a drive. When the cleaning prongs pass the screen, they engage at least in sections between adjacent grate bars to remove the material to be sieved and held back by the screen, thereby conveying it towards a discharge. The cleaning prongs may be configured to be movable laterally back and forth with regard to the conveying direction and with regard to the screen.

Abstract: A device for separating and removing sieve material from a flowing liquid includes a sieve grate that forms a sieve surface and is fixed to a frame. The sieve grate has several grate bars arranged beside one another and with at least some sections separated from one another by spaces. At least one cleaning rake has numerous cleaning prongs, the cleaning rake being movable along the front side of the sieve grate using a drive in such a way that at least sections of the cleaning prongs engage in the above-mentioned spaces when passing the sieve grate to remove sieve material held back by the sieve grate and convey it toward a device discharge. The cleaning rake has cleaning prongs that engage with variable depth into the above-mentioned spaces of the sieve grate.

Abstract: This invention refers to a device for separating and removing sieved material from a flowing liquid such as sewage, in which case the device has a sieve grate (1) with a sieve surface with a front side (2) pointing upstream while the device is operating, in which case the device has a supplementary grate (3) in a lower area of the sieve grate (1) placed upstream before the sieve grate (1), in which case the device has a drive (24) and a cleaning rake (4) that can be driven to revolve in a conveying direction with the help of the drive (24), in which case the operating cleaning rake (4) is moveable along at least one partial section of the front side (2) of the sieve grate (1) in order to remove the held-back sieved material and transport it towards a discharge opening (5) and wherein the cleaning rake (4) can be moved along a back side (6) of the supplementary grate (3) pointing downstream while it is moving in order to remove sieved material held back by the supplementary grate (3) and transport it towards a
