Abstract

An assembly that includes a particle collecting container and a cyclone pre-separator placed on the particle collecting container, where the particle collecting container has a rectangular container bottom and four container peripheral walls which extend upwards from the container bottom and define a horizontal outer contour of the particle collecting container, and where the cyclone pre-separator has a particle outlet which is designed to dispense particles which have been separated in the cyclone pre-separator into the particle collecting container. The horizontal outer contour defined by the container peripheral walls tapers towards the container bottom and the particle collecting container can be stacked into an identical particle collecting container.

First claim

The invention claimed is:

1. An assembly comprising:
a particle collecting container and a cyclone pre-separator placed on the particle collecting container,
wherein the particle collecting container has a rectangular container bottom and four container peripheral walls which extend upwards from the container bottom and define a horizontal outer contour of the particle collecting container, and
wherein the cyclone pre-separator has a particle outlet which is designed to dispense particles which have been separated in the cyclone pre-separator into the particle collecting container,
wherein the horizontal outer contour defined by the container peripheral walls tapers towards the container bottom and the particle collecting container can be stacked into an identical particle collecting container.

2. The assembly according to claim 1 , comprising an additional particle collecting container identical to the particle collecting container.

3. The assembly according to claim 1 , wherein the particle collecting container is produced by injection moulding.

4. The assembly according to claim 1 , wherein the wall planes of the four container peripheral walls are inclined away from the normal vector of the container bottom so that container peripheral walls together make the shape of an inverted truncated pyramid periphery.

5. The assembly according to claim 1 , wherein the cyclone pre-separator is positioned with its underside on the upper side of the particle collecting container, wherein the horizontal outer contour of the upper side of the particle collecting container is positioned within the horizontal outer contour of the underside of the cyclone pre-separator.

6. The assembly according to claim 1 , wherein the particle collecting container has container couplers arranged on two opposing container peripheral walls and can engage with lower housing couplers of the cyclone pre-separator, in order to provide a releasable, vertically tension-proof coupling between the particle collecting container and the cyclone pre-separator.

7. The assembly according to claim 1 , wherein the container peripheral walls have a upper edge on which a surrounding seal is arranged.

8. The assembly according to claim 1 , wherein the particle collecting container has container handles on two opposing container peripheral walls.

9. The assembly according to claim 8 , wherein the container handles are designed as spacers which when the particle collecting container is stacked in an identical particle collecting container, ensure a predetermined vertical distance between the two upper surfaces of the inter-stacked particle collecting containers.

10. The assembly according to claim 9 , wherein the container handles have horizontal bars and vertical bars and are designed so that when the particle collecting container is stacked in an identical particle collecting container, lower edges of the vertical bars rest on the upper surface of the identical particle collecting containers thereby ensuring the specified vertical distance.

11. The assembly according to claim 8 , further comprising a bow-shaped carrying handle which when the cyclone pre-separator is removed from the particle collecting container can be attached to the container handles of the particle collecting container.

12. The assembly according to claim 1 , wherein the particle collecting container has on the underside of the container bottom carrying indentations.

13. The assembly according to claim 1 , also comprising a container cover, which when the cyclone pre-separator is removed from the particle collecting container, can be positioned on the particle collecting container, wherein on the upper side of the container cover an indentation is provided, designed to correspond with the container bottom of the particle collecting container so that an identical particle collecting container can be stacked on the container cover in a stable manner.

14. The assembly according to claim 13 , wherein the container cover is designed so that it can be stacked in an identical container cover.

15. The assembly according to claim 13 , wherein the horizontal external dimensions of the container cover correspond to the horizontal external dimensions of the upper side of the cyclone pre-separator.

16. The assembly according to claim 2 , wherein the particle collecting container is stacked in the additional particle collecting container.

17. The assembly according to claim 6 , wherein the container couplers are non-movable container couplers.
