The invention concerns a method and a device for the separation of substantially solid bodies accompanying a liquid flow (60). An obliquely arranged screen grid (10) with an upper region (13), a lower region (14), and two opposite edge regions (11a, 11b) is supplied with the liquid flow at the upper region of the screen grid so as to pass whilst separating substantially solid bodies from the liquid flow to form screenings along the upwards facing surface (15) of the screen grid and/or through the screen grid. A cleaning device (40) having cleaning means (46) rests against the upwards facing surfce (15) of the screen grid and moves the screenings during movement of the cleaning means mainly in the horizontal plane towards the edge regions (11a, 11b), which pass over into connecting means (17a, 17b) situated outside said regions for receiving screenings (50) carried along by the movement of the cleaning means (46). The connecting means have an upwards facing transport surface (12a, 12b) extending along the whole length of the screen grid along which surface the screenings are moved towards the lower part (3) of the device. To facilitate the movement of the screenings (50) the transport surface (12a, 12b) is formed e.g. as a completely smooth surface. |
