Abstract:
A shower header type spray device has a motorized cleaning brush on a rotary shaft mounted therein for cleaning inlet apertures of its spray nozzles. The brush shaft is supported to impart axial movement when it is rotated, and has a sealing valve attached thereon such that when the brush is rotated by the motor in a cleaning operation the valve is opened to allow discharge of liquid with debris brushed off the nozzle inlets. The motor is activated for a cleaning operation from either a local controller or a centralized controller that controls multiple spray devices.
Abstract:
A spray nozzle for directing a wide lateral spray curtain with substantially uniform liquid distribution throughout the length of the spray curtain is provided. The nozzle includes a nozzle body defining an elongated internal flow passage. The nozzle body includes an inlet end for connection to a pressurized liquid supply, a downstream end wall and a side wall. A discharge orifice is provided in the side wall of the nozzle body between the inlet end and the downstream end wall. The discharge orifice communicates with the internal flow passage of the nozzle body. The discharge orifice has a generally inverted teardrop configuration comprising a relatively larger area upper portion and a relatively smaller area lower portion arranged below the upper portion.
Abstract:
An external mix air assisted spray nozzle assembly having a nozzle body, and an air cap for a directing pressurized air streams on a discharging liquid stream external to the liquid discharge orifice of the nozzle assembly for atomizing and forming the liquid into the desired spray pattern. The air cap includes an upstream internal air chamber, an external, downstream liquid discharge and mixing chamber, and a central opening coaxial with the liquid discharge orifice communicating between the upstream and downstream chambers. The air cap further includes a plurality of angled pressurized air discharge passages which communicate with an annular plenum of the air chamber disposed in surrounding relation to the central opening for enabling substantially uniform particle breakdown and distribution at lower air pressures than heretofore possible.
Abstract:
A spray bar having a plurality of laterally spaced nozzles mounted in a row on a header block for discharging a row of liquid spray patterns, and a method of manufacture. The spray bar header includes a plurality of separate plates, each formed with a plurality of nozzle-receiving apertures and with one or more faces of adjacent interfacing plates being formed with grooves which define fluid passages for the supply liquid, atomizing and nozzle-actuating air, and heating fluid. The plates preferably are electroplated/electropolished for thorough and efficient cleaning upon disassembly.
Abstract:
An air assisted spray nozzle assembly, having particular utility in spraying liquid coolants in continuous metal casting systems, which is adapted for operation with substantially reduced air consumption. The nozzle body includes a pre-atomizing unit that has a relatively small sized pressurized air inlet, a liquid impingement post with a uniquely configured impingement face for enhancing liquid breakdown and intermixing with a pressurized air stream from the air inlet, and an expansion chamber configured to reduce eddy currents that detract from efficient pre-atomization of the liquid. The spray nozzle further includes an elongated spray tip supporting barrel adapted for releasable mounting in the pre-atomizing head in predetermined rotational orientation relative to its longitudinal axis for properly receiving and supporting a removable spray tip.

990,853. Spray - producers. SPRAYING SYSTEMS CO. Jan. 28, 1964 [June 17, 1963], No. 3576/64. Heading B2F. A spray head 20 for a paint spray gun comprises an elongated body 21 having a longitudinal passage 22 extending axially thereof, a generally cylindrical member 26 disposed within said body for rotation about an axis substantially at right angles to said passage between a spraying position, Fig. 1, and a cleaning position in which the member 26 is rotated through 180 degrees, said member being provided with a diametric bore 35 adapted to be aligned with said longitudinal passage in both of said positions, and a lock nut 56 arranged to hold a spray orifice member 36 within said bore. The opening 38 through which the spray passes is sufficiently large to allow removal of the nut 56 and the member 36 when the member 26 is in the cleaning position. Alternatively the nozzle may be cleaned by a reverse flow of paint &c. through the orifice member. The member 26 is rotatable between stops by a handle 28 and the orifice member 36 may be replaced by one of different capacity located at a selected position within said bore, Fig. 2 (not shown). In the embodiments of Figs. 3 and 4 (not shown) the orifice member is mounted in an adapter ring or tip holder.
