Abstract

The disclosure relates to a paint mist separating device, and a paint booth having a paint mist separating device. The paint mist separating device can include a tapered tube, and a collecting funnel with a funnel inlet and a funnel neck, into which the larger end of the tapered tube projects, wherein the funnel neck is provided for connection to a collecting tank for paint. The paint mist separating device can include a collecting hood, which is arranged opposite the funnel inlet and which has a paint mist inlet opening, into which a smaller end of the tapered tube opens, wherein an outlet gap is provided between the inlet opening of the collecting funnel and the collecting hood.

First claim

What is claimed is:

1. A paint mist separating device, comprising:
a tapered tube;
a collecting funnel with a funnel inlet and a funnel neck, a larger end of the tapered tube projecting toward the funnel neck, wherein the funnel neck is provided for connection to a collecting tank for paint; and
a collecting hood arranged opposite the funnel inlet, the collecting hood having a paint mist inlet opening, into which a smaller end of the tapered tube opens, wherein an outlet gap is provided between the inlet opening of the collecting funnel and the collecting hood.

2. The paint mist separating device according to claim 1 , wherein the collecting funnel has a shape extended as a tube at an inlet end thereof.

3. The paint mist separating device according to claim 1 , wherein the collecting funnel is surrounded along an axial extent thereof by a cylindrical wall connected at one end to the protective hood, wherein a through-flow gap is formed in a radial direction between the funnel inlet and the cylindrical wall.

4. The paint mist separating device according to claim 1 comprising:
a ringed restriction element arranged to construct the paint mist inlet opening.

5. The paint mist separating device according to claim 1 , wherein an angle of taper of the tapered tube is in a range of from 10° to 50°.

6. The paint mist separating device according to claim 1 , wherein the device is manufactured at least partially from stainless steel.

7. The paint mist separating device according to claim 1 , in combination with an atomizer, wherein the tapered tube is arranged along an axis of rotation and the atomizer is aligned along the axis of rotation and positioned above the pain mist inlet opening.

8. A paint booth, comprising:
at least one painting device; and
a dry separation system including at least one paint mist separating device having:
a tapered tube;
a collecting funnel with a funnel inlet and a funnel neck, a larger end of the tapered tube projecting toward the funnel neck, wherein the funnel neck is provided for connection to a collecting tank for paint; and
a collecting hood arranged opposite the funnel inlet, the collecting hood having a paint mist inlet opening, into which a smaller end of the tapered tube opens, wherein an outlet gap is provided between the inlet opening of the collecting funnel and the collecting hood.

9. The paint booth according to claim 8 , wherein the collecting funnel has a shape extended as a tube at an inlet end thereof.

10. The paint booth according to claim 8 , wherein the collecting funnel is surrounded along an axial extent thereof by a cylindrical wall connected at one end to the protective hood, wherein a through-flow gap is formed in a radial direction between the funnel inlet and the cylindrical wall.

11. The paint booth according to claim 8 comprising:
a ringed restriction element arranged over the paint mist inlet opening.

12. The paint booth according to claim 8 , wherein an angle of taper of the tapered tube is in a range of from 10° to 50°.

13. The paint booth according to claim 8 , wherein the device is manufactured at least partially from stainless steel.

14. The paint booth according to claim 8 , comprising:
a painting robot provided for carrying the at least one painting device.

15. The paint booth according to claim 8 , comprising:
an atomizer wherein the tapered tube is arranged along an axis of rotation and the atomizer is aligned along the axis of rotation and positioned above the pain mist inlet opening.
