Abstract
The mixing device for mixing a powder with a pressurized gas, comprising a mixing chamber (20) with an inlet area (22), which has at least one inlet opening (24), by way of which powder and/or pressurized gas and/or a mixture thereof may be introduced into the mixing chamber (20), and at least one outlet area (26), which is designed for withdrawing from the mixing chamber (20) a main flow (HR) of a gas or powder or a powder and gas mixture directed along the mixing chamber (20) which essentially extends from the inlet area (22) to the outlet area (26), characterized in that a regulating device (10) is arranged along and/or in continuation of the main flow (HR), regulating the main flow (HR) of the gas or powder or powder and gas mixture.
Claims19
A mixing device for mixing a powder with pressurized gas, comprising:
- a mixing portion having an inner surface, an outer surface, a first end proximal to an inlet area and a second end proximal to an outlet, wherein a mixing chamber is defined by the inner surface of the mixing portion and extends along a first axis from the inlet area to the outlet, the inlet area including at least one inlet opening, by way of which at least one of a powder or pressurized gas is introducible into the mixing chamber, the mixing chamber having a regulating device with a plurality of regulating orifices at an end of the mixing chamber, wherein the regulating orifices are an only outlet pathway for withdrawing from the mixing chamber a main flow, the main flow of the introduced powder or pressurized gas flowing through the mixing chamber, wherein the plurality of regulating orifices of the regulating device are in fluid communication with the mixing chamber and are configured to be in direct communication with a turbulence chamber, wherein the mixing portion includes a plurality of supporting bars proximal to the second end of the mixing chamber and formed as radial ribs forming an extended plane and extending radially outward from the outer surface of the mixing portion, and wherein the regulating device and the support bars regulate the main flow.
A mixing device, comprising:
- a mixing portion, having an inner surface, an outer surface, and extending from a first end to a second end, the mixing portion having at least one inlet area proximal to the first end, an outlet area proximal to the second end of the mixing portion, a mixing area at least partially defined by the inner surface and extending from the at least one inlet area to the outlet area, and a plurality of supporting bars proximal to the second end of the mixing portion and formed as radial ribs forming a series of extended planes extending radially outward from the outer surface of the mixing portion, wherein the mixing area is configured to receive at least one selected from a group consisting of a powder or a pressurized gas;
- a regulating device with a plurality of regulating orifices at the second end of the mixing portion and forming a plurality of passages extending from the inner surface to the outer surface of the mixing portion, wherein the regulating orifices are an only pathway out of the mixing area, wherein the regulating device and the supporting bars regulate a main flow of the at least one of the powder or a pressurized gas;
- and
- a turbulence chamber, wherein the turbulence chamber is in direct fluid communication with the plurality of regulating orifices of the regulating device and the turbulence chamber is configured to receive at least one of the powder or a gas.

A mixing device, comprising:
- a mixing portion having an inner surface, an outer surface, at least one inlet area at a first end of the mixing portion, an outlet area at a second end of the mixing portion, and a mixing chamber at least partially defined by the inner surface and extending from the at least one inlet area to the outlet area, wherein the mixing chamber is formed as a conical extension, and has an axis extending from the inlet area to the outlet area, the mixing chamber being configured to receive at least one selected from a group consisting of a powder or a pressurized gas;
- a plurality of supports at the second end of the mixing portion and formed as radial ribs forming an extended plane that extends radially outward from the outer surface of the mixing portion;
- and
- a regulating device at the outlet area of the second end of the mixing portion with a plurality of regulating orifices extending from the inner surface to the outer surface of the mixing portion, wherein the regulating orifices are an only outlet pathway of the mixing chamber, wherein the regulating device and plurality of supports regulate a flow of the at least one selected from the group consisting of the powder or the gas exiting the mixing chamber.
