Abstract

The invention relates to a device for additively producing at least one component region of a component, in particular a component of a turbomachine. The device can comprise at least one coating apparatus for applying at least one powder layer of a component material to at least one build-up and joining zone of at least one component platform, which can be lowered, wherein the coating apparatus can be moved in relation to the component platform. In addition, the device comprises at least one suction device for suctioning of process waste gases and/or particles. The coating apparatus thereby comprises at least one suction channel or at least one suction pipe, which has at least one suction opening oriented in the direction of the component platform.

First claim

The invention claimed is:

1. A device for additively producing at least one component region of a component of a turbomachine, comprising:
at least one coating apparatus for applying at least one powder layer of a component material onto at least one build-up and joining zone of at least one component platform, which can be lowered, wherein the coating apparatus can be moved in relation to the component platform; and
at least one suction device for suctioning of process waste gases and/or particles directly from the at least one build-up and joining zone to at least one overflow tank,
wherein the coating apparatus comprises at least one suction channel or at least one suction pipe with at least one suction opening oriented in the direction of the component platform, wherein the suction channel or the suction pipe is arranged in such a way that, in a predefined standstill position of the coating apparatus outside of the component platform, the suction channel or the suction pipe is operatively connected to the suction device for diverting a gas flow and/or a particle flow directly to the at least one overflow tank, and
wherein in each case, the suction channel or the suction pipe has a first and a second end, wherein the first end is designed to face the suction device, and comprises at least one opening and, in the predefined standstill position of the coating apparatus, the opening comes into alignment at least in part with at least one opening of the suction device, such that the first end is docked with the at least one opening of the suction device.

2. The device according to claim 1 , wherein the suction channel or the suction pipe is a separate component and is arranged at a housing of the coating apparatus.

3. The device according to claim 1 , wherein the suction channel or the suction pipe is one piece with a housing of the coating apparatus.

4. The device according to claim 1 , wherein the suction device is arranged in a region of an overflow tank and/or in a region of a stock supply and/or metering tank of the device.

5. The device according to claim 1 , wherein the device comprises at least one gas supply device for supplying at least one gas and/or one process gas at least into the region of the component platform.

6. The device according to claim 1 , wherein the opening of the first end of the suction channel or the suction pipe and/or the opening of the suction device have or has a sealing lip.

7. The device according to claim 1 , wherein the second end of the suction channel or the suction pipe is closed.
