Abstract
A de-dusting unit positionable in a vacuum chamber of a vacuuming device, where the vacuum chamber is delimited by a turbine, a first filter, and a second filter. The de-dusting unit includes a displacement module where the de-dusting unit is positionable within the vacuum chamber by the displacement module such that one of the first and second filters at a time is isolated from a suction flow and such that an oscillating movement of the de-dusting unit is transmitted to the isolated filter.
Claims15
A vacuuming device, comprising:
- a vacuum chamber (2), wherein the vacuum chamber (2) is delimited by a turbine (3), a first filter (4), and a second filter (5);
- and
- a single de-dusting unit (1) disposed in the vacuum chamber (2), wherein the single de-dusting unit (1) comprises:
- a single displacement module (6), wherein the single displacement module (6) is an actuator that moves the single de-dusting unit (1) back and forth within the vacuum chamber (2) between a first de-dusting position, in which the single de-dusting unit (1) is exclusively in contact with the first filter (4), and a second de-dusting position, in which the single de-dusting unit (1) is exclusively in contact with the second filter (5), such that one of the first and second filters (4, 5) at a time is isolated from a suction flow and such that a mechanically produced oscillating movement of the single de-dusting unit (1) is transmitted to the isolated filter (4, 5);
- wherein the oscillating movement produced by the single de-dusting unit (1) is transmitted to the first filter (4) when the single de-dusting unit (1) is in the first de-dusting position;
- wherein the oscillating movement produced by the single de-dusting unit (1) is transmitted to the second filter (5) when the single de-dusting unit (1) is in the second de-dusting position.

A vacuuming device, comprising:
- a vacuum chamber (2), wherein the vacuum chamber (2) is delimited by a turbine (3), a first filter (4), and a second filter (5);
- a single de-dusting unit (1) disposed in the vacuum chamber (2), wherein the single de-dusting unit (1) comprises an eccentric unit (9) with two eccentric (7,8) and comprises a first tappet (10) and a second tappet (11);
- and
- a displacement module (6), wherein the single de-dusting unit (1) is laterally movable back and forth within the vacuum chamber (2) by the displacement module (6) such that one of the first and second filters (4, 5) at a time is isolated from a suction flow and such that a mechanically produced oscillating movement of the single de-dusting unit (1) is transmitted to the isolated filter (4, 5);
- wherein the first tappet (10) and the second tappet (11) form respective lateral terminations of the single de-dusting unit (1) such that a first inlet (12) of the first filter (4) is sealable off by the first tappet (10) when the single de-dusting unit (1) is laterally moved to a first de-dusting position within the vacuum chamber (2) by the displacement module (6) and wherein a second inlet (13) of the second filter (5) is sealable off by the second tappet (11) when the single de-dusting unit (1) is laterally moved to a second de-dusting position within the vacuum chamber (2) by the displacement module (6);
- wherein the two eccentrics (7, 8) are disposed between the first tappet (10) and the second tappet (11);
- wherein the two eccentrics (7, 8) produce the oscillating movement that is transmitted to the first filter (4) when the first filter (4) is isolated and to the second filter (5) when the second filter (5) is isolated by a rotational movement of the two eccentrics (7, 8) in a same direction, but with an offset of 180° in relation to one another;
- wherein the oscillating movement produced by the two eccentrics (7,8) is transmitted to the first filter (4) when the first filter (4) is isolated by the first tappet (10);
- wherein the oscillating movement produced by the two eccentrics (7,8) is transmitted to the second filter (5) when the second filter (5) is isolated by the second tappet (11).
