Mixing device comprising at least four outlet arms having diverse vertical angles

A fluid system for a dye in a printing machine, comprising:

• a mixing device for mixing a fluid in at least one container,
• a flow pump;
• a return flow pump for a conveyance of the fluid,
• a print roller;
• and
• a fluid tank for provision and/or collection of the fluid for and/or from a fluid receptor;
• wherein the flow pump is formed for a conveyance of the fluid from the container to the fluid receptor and the return flow pump is formed for a conveyance of the fluid from the fluid tank back to the container,
• wherein the mixing device comprises a fluid supply connected to at least four outlet arms, each of the at least four outlet arms having an outlet opening connected to the fluid supply in a fluid communicating way,
• wherein the fluid supply comprises at least one additional opening in an area of connection to the at least four outlet arms so that eventually formed clearance volumes below an area between the fluid supply and the at least four outlet arms are avoided or reduced,
• wherein an outlet opening is aligned with an outlet direction (A) for the outlet of the fluid, in order to at least partially set the fluid in the at least one container in rotation,
• wherein said at least one additional opening has an outlet direction alongside an axis of said rotation and toward a bottom of said container,
• wherein the at least four outlet arms are at least partially curved,
• wherein the fluid supply of the mixing device is connected with a pressure side of the return flow pump in a fluid communicating way, and
• wherein the outlet openings of the at least four outlet arms have diverse vertical angles with different signs toward the horizontal level.
