Abstract
A material deposition device includes a solution supply component, a gas supply component, and a co-axial discharge mechanism. The co-axial discharge mechanism includes a solution discharge mechanism, and a gas discharge mechanism co-axial with the solution discharge mechanism. The material deposition device further includes an alignment component that aligns the solution discharge mechanism in a center of the gas discharge mechanism; and an orifice plate with a number of turbulence inducing structures that induce turbulence in gas exiting the gas discharge mechanism.
Claims10
A material deposition device, comprising:
- a solution supply providing a solution;
- a gas supply providing a gas;
- a discharge device disposed in a center of a discharge orifice plate and a center of a device housing, the discharge device comprising:
- a solution discharge device, comprising:
- an elongated center section defined by a longitudinal axis of the solution discharge device;
- a supply end of the elongated center section that receives the solution from the solution supply;
- and
- a discharge end of the elongated center section comprising a solution discharge port that directs the solution beyond the solution discharge port in a direction along the longitudinal axis of the solution discharge device, and
- a gas discharge device co-axial with the solution discharge device, the gas discharge device comprising a gas cavity that directs the gas into a flow co-axial with the solution,
- a discharge device aligner comprising a centering channel that holds the solution discharge device centered in the housing and the orifice plate, the centering channel defining an inner surface, the centering channels, comprising:
- a first portion of the inner surface, the first portion comprising one or more spiral grooves formed on the inner surface at a first portion of the inner surface of the central channel, and
- a second portion adjacent to and downstream of the first portion, the second portion comprising an expanding chamber adjacent the orifice plate;
- and
- the orifice plate comprising:
- an opening centered in the orifice plate, the discharge device protruding through the opening past an outer surface of the orifice plate and directing a discharge of the solution, and a first portion of the gas exiting the gas discharge device through the opening, and
- a plurality of gas discharge orifices disposed parallel to the longitudinal axis, a second portion of the gas exiting the gas discharge device through the orifices, the orifices centered on and spaced away from the opening.
