摘要： The invention relates to a suction dredge for receiving and separating suction material (12, 12') with a pneumatic suction turbine (5) which is connected to a collecting tank (1). A suction tube (7) leads into said collecting tank and a large part of the suction material is fed into said tank. The suction dredge also comprises a filter chamber (2) with a plurality of filters (10, 10') through which the suction air flow (11, 11', 11'') is guided for fine-filtering. The collecting tank and the filter chamber are separated by a partition (8) which comprises a through-hole (9) for the suction air flow. Said suction air flow (11, 11', 11'') is directed to the upper part of the wall (25) of the collecting tank opposite the partition (8). Said through-hole (9) of the partition is located in the upper part thereof so that a cyclone-type suction air current about a vertical axis is produced in the collecting tank. The suction air flow impacts the filter (10, 10') in a substantially vertical direction. The inlet of the air suction flow into the collecting tank and the outlet of the suction air flow (13) from the filters are displaced from one another by 180 DEG to 270 DEG .

摘要： Die Erfindung betrifft ein mehrstufiges Sauggebläse mit mindestens zwei aus jeweils einem Gehäuse und einem darin angeordneten Flügelrad bestehenden, aufeinander folgend angeordneten, antreibbaren Radialgebläsen, bei dem die Ausblasöffnung des jeweils ersten Radialgebläses mit der Einsaugöffnung des jeweils zweiten Radialgebläses durch jeweils einen Strömungskarial verbunden ist, bei dem die aufeinander folgend angeordneten und jeweils durch einen Strömungskanal miteinander verbundenen Radialgebläse relativ zueinander versetzt auf voneinander getrennten Antriebswellen angeordnet sind, so dass in dem Strömungskanal zwischen der Ausblasöffnung des ersten und der Einsaugöffnung des zweiten Radialgebläses eine Strömungsumlenkung um weniger als 180° erfolgt. Vorzugsweise beträgt die Strömungsumlenkung nur 90°.

摘要： The invention relates to a suction dredger (1) for receiving suctioned material, such as soil around subterranean pipe lines or mud, with a pneumatic suction turbine (2) for generating a suction air flow, which is connected to a collecting container (3), into which a suction hose (4) opens, wherein the suction hose (4) is designed to be movable by a guide arm (5) rotatable on a vertical axis of rotation (6), in order to extend the working range of the suction dredger. The subject matter of the invention solves this problem by designing a vertical axis of rotation (6) of the guide arm (5) so as to be movable.

摘要： The invention relates to a method for pneumatically picking up soil for suction dredges, using a suction tube (3) having a crown (11) disposed at the lower end and an air supply device (10) for supplying pressurized air to the crown (11), thereby producing a pressurized air flow which loosens the soil in the area of the crown (11). The pressurized air flow below the crown (11) is blown into the soil in parallel to the cross-sectional plane of the crown (11), thereby detaching a soil core which has approximately the same size as the internal width of the crown (11) or smaller and which is sucked off through the suction tube (3). The invention also relates to a device for carrying out the inventive method which comprises at least one pointed tube (1) which projects beyond the crown (11) downward in the direction parallel to the center axis (30) of the suction tube (3). Said pointed tube is adapted for blowing a pressurized air flow into the soil below the crown (11) in parallel to a cross-sectional plane of the same for detaching a soil core and sucking the same off through the suction tube (3).
