Patent DE-4306135-A1 (DE)
Inventor: RINKER KARL DIPL ING
IPC: B01D50/00
Filed: 1993-02-27
Abstract: The invention relates to an excavator (1) for specifically picking up material by suction, in particular for excavating earth at buried lines. The excavator (1) has a pneumatic suction pipe (3) for picking up the material. The suction pipe (3) opens out in a collecting tank (2) for the sucked-up material. A suction fan (4) is attached to the collecting tank (2). In the collecting tank (2), the material is separated from the suction-air flow and is then passed through a filter device (6) arranged between the opening of the suction pipe (3) and the suction fan (4). In order to ensure effective separation by the filter device (6) for as long a time as possible, the filter device (6) is formed by a coarse filter (6a) and an adjoining fine filter (6b), the coarse filter (6a) being formed by a labyrinth- or cascade-shaped flow passage which is defined by dividing walls (7a) offset from one another and whose cross-section of flow increases in the direction of flow. A conveyor device (23) can be provided at the base of the collecting tank (2). The material separated from the air flow can be discharged continuously or at intervals from the collecting tank (2) by means of the conveyor device (23). <IMAGE>
