Abstract

A cyclone pre-separator for positioning on a particle collecting container, the cyclone pre-separator including a box-shaped housing and a cyclone unit arranged in the housing, the cyclone unit including an air inlet, an air outlet, and a particle outlet arranged on a underside of the cyclone pre-separator, where the housing has an air inlet hose port connected to the air inlet and an air outlet hose port connected to the air outlet, and has lower housing couplers, adapted to provide a releasable, vertically tension-proof coupling to the particle collecting container, when the cyclone pre-separator is positioned on the particle collecting container.

Claims (31)

1. A cyclone pre-separator for positioning on a particle collecting container, the cyclone pre-separator comprising:

a box-shaped housing having a substantially cuboid shape; and

a cyclone unit arranged in the housing, the cyclone unit comprising an air inlet, an air outlet,and a particle outlet arranged on a underside of the cyclone pre-separator,

wherein the housing has an air inlet hose port connected to the air inlet and an air outlet hose port connected to the air outlet, and has lower housing couplers, adapted to provide a releasable, vertically tension-proof coupling to the particle collecting container, when the cyclone pre-separator is positioned on the particle collecting container,

wherein the cyclone unit comprises an inlet cylinder arranged within the box-shaped housing, an air inlet pipe and an air outlet pipe arranged in the box-shaped housing,

wherein the air inlet pipe provides the air inlet and provides a fluidic connection between the air inlet hose port and the inlet cylinder, and wherein the air outlet pipe provides the air outlet and provides a fluidic connection between the inlet cylinder and the air outlet hose port,

wherein the air inlet pipe and the air outlet pipe are arranged completely in the box-shaped-housing, and

wherein gaps or spaces are provided between the box-shaped housing and the cyclone unit within the box-shaped housing.

2. The cyclone pre-separator of claim 1 , wherein the box-shaped housing has four peripheral walls aligned orthogonally to each other.

3. The cyclone pre-separator of claim 2 , wherein the air inlet hose port and the air outlet hose port are arranged on the same peripheral wall of the box-shaped housing.

4. The cyclone pre-separator of claim 3 , wherein the air inlet hose port and the air outlet hose port are openings within the same peripheral wall of the box-shaped housing.

5. The cyclone pre-separator according to claim 1 , wherein the housing has upper housing couplers, which are adapted to provide, in a state, in which a box-shaped body is stacked on the housing, a releasable, vertically tension-proof coupling to the box-shaped body.

6. The cyclone pre-separator according to claim 5 , wherein the air inlet hose port and the air outlet hose port are arranged on one of the peripheral sides of the housing.

7. The cyclone pre-separator according to claim 5 , wherein the cyclone pre-separator comprises a socket and/or the housing comprises a socket recess to accept a socket insert.

8. The cyclone pre-separator according to claim 5 , wherein on the underside of the cyclone pre-separator a groove is provided, which runs along the outer edge of the underside and is adapted to receive the upper edge of the particle collecting container.

9. The cyclone pre-separator according to claim 5 , further comprising a bow-shaped carrying handle, arranged on the upper side of the housing.

10. The cyclone pre-separator according to claim 5 , wherein the upper housing couplers comprise a movably mounted locking element.

11. The cyclone pre-separator according to claim 5 , wherein the lower housing couplers comprise at least one movably mounted locking element.

12. The cyclone pre-separator according to claim 11 , wherein the lower housing couplers are provided on longitudinal sides of the housing.

13. The cyclone pre-separator according to claim 5 , wherein the housing has a removable and/or pivotable cover, which in an open position allows access to the cyclone unit.

14. The cyclone pre-separator of claim 13 , wherein the cover forms the entire upper side of the box-shaped housing.

15. The cyclone pre-separator according to claim 13 , wherein the upper housing couplers comprise a rotary latch, arranged on the cover and adapted both for locking the cover and for providing the coupling to the box-shaped body.

16. The cyclone pre-separator of claim 15 , wherein the rotary latch has a T-shaped form.

17. The cyclone pre-separator of claim 15 , wherein the rotary latch can be rotated in at least three different positions.

18. A cyclone pre-separator for positioning on a particle collecting container, the cyclone pre-separator comprising:

a box-shaped housing having a polygonal shape; and

a cyclone unit arranged in the housing, the cyclone unit comprising an air inlet, an air outlet, and a particle outlet arranged on a underside of the cyclone pre-separator, wherein the housing has an air inlet hose port connected to the air inlet and an air outlet hose port connected to the air outlet, and has lower housing couplers, adapted to provide a releasable, vertically tension-proof coupling to the particle collecting container, when the cyclone pre-separator is positioned on the particle collecting container,

wherein the cyclone unit comprises an inlet cylinder arranged within the box-shaped housing, an air inlet pipe and an air outlet pipe arranged in the box-shaped housing,

wherein the air inlet pipe provides the air inlet and provides a fluidic connection between the air inlet hose port and the inlet cylinder, and wherein the air outlet pipe provides the air outlet and provides a fluidic connection between the inlet cylinder and the air outlet hose port,

wherein the air inlet pipe and the air outlet pipe are arranged completely in the box-shaped-housing, and

wherein gaps or spaces are provided between the box-shaped housing and the cyclone unit within the box-shaped housing.
