Definitions
- the present invention has a suction device with a Air intake opening and an air outlet opening Suction pipe to the object in the area of its air intake one connected to a pressure source, directed in the suction direction Has injector opening from the primary air into the Intake pipe flows, being in the area of the air intake opening there is an additional air inlet opening in the intake manifold.
- EP-A-0 587 272 is a suction device with a Air intake opening and an air outlet opening Suction pipe known.
- This suction pipe has in the area of its air intake opening one connected to a pressure source, in the suction direction open inlet opening, from the primary air into the Intake pipe flows.
- Located in the area of the air intake an additional air inlet opening in the intake manifold the ambient air is drawn into the intake manifold.
- the suction device attached to the floor flows into the ambient air same direction as the primary air flowing into the intake manifold the suction pipe.
- the opening cross-section is the inlet opening chosen so large that it covers the entire opening cross-section of the suction pipe near the suction opening as possible uniform secondary air flow, i.e.
- the object of the present invention is therefore in a suction device of the type mentioned the suction effect for relative to improve heavy objects.
- Air inlet opening can be a "sweeping" for difficult ones promoting suction material in the direction of the injector nozzle and thus in the direction stronger suction effect. This allows in the Objects located away from primary air through the secondary air flowing in the additional air inlet opening "turned" to the high-energy air conveyor belt and close to the primary air Area of the intake opening.
- This additional air intake opening can, for example through a hole in the wall of the suction pipe, Recess or the like. Be formed.
- this becomes additional Air intake opening by angling the front edge the plane defining the air intake opening, then this bend expediently to an edge area of this limited by the face edge of the air intake opening is.
- the attached drawing shows the longitudinal section of the bottom End 1 of a suction device not shown associated suction pipe 2, the air intake opening designated 3 is.
- This suction pipe 2 is with two axially directed Air channels 4 and 5 equipped, in the direction of the arrows 6 and 7 of one belonging to the suction device and also Air pressure source not particularly shown compressed air supplied becomes.
- the air duct 4 has an injector nozzle 8 through which the primary air supplied through this air duct 4 in the direction of arrow 9 and thus approximately in the suction direction 10 blown into the interior 11 of the suction pipe 2 and so through the air intake opening 3 entering the intake pipe 2 secondary air 12 is carried away.
- Air duct 5 leaves and in the direction of arrows 14 to the 15th designated floor.
