    Abstract: An air assisted electrostatic liquid spray nozzle assembly having a relatively long elongated nozzle body with a spray tip and surrounding air cap disposed at a downstream end of the nozzle body. The spray nozzle assembly includes an upstream electrode for connection to a high voltage electric source, an elongated feed tube, an electrically enhancing stinger, and the spray tip which are secured and retained by the air cap in electrically conductive relation to each other such that liquid passing through liquid passages of the electrode, feed tube, stinger, and spray tip is discharged in an electrostatically charged pattern of liquid particles. The air cap is removable to permit easy removal and replacement of the spray tip, stinger, and liquid feed tube.

    Abstract: An electrostatic coater capable of realizing high-level coating quality is provided. Shaping air SA, discharged from an air port, is directed radially outward. An elevation angle thereof preferably ranges from 10 to 20 degrees. Further, the shaping air SA is a flow in a state of being twisted in a direction opposite to the rotation direction R of a bell cup. The twisting angle about the axis O of the bell cup preferably ranges from 38 to 60 degrees. A liquid thread of paint extends radially outward from the outer peripheral edge of the bell cup, and the paint separated from the tip end thereof becomes a particle. It is preferable that the shaping air SA collides with the paint particle at a point P where the momentum of the paint particle is decreased of the paint particle is decreased.

    Abstract: The present invention relates to a process of forming copper anodes (6) in a casting wheel (I) from the stage in which the copper is in liquid molten state (5) in a dumping chute (3) and is transferred to a ladle (4) until the anode (6) of solid copper is transformed into an anode (6) and is discharged from a mold (2) located in said casting wheel (I) wherein said process prevents the liquid molten copper (5) from being adhered to the edge of the ladle (4) and in the interstice (14) generated between the surfaces of the ejector rod (13) and the passing through bore (12) located on the mold (2) comprising the stages of: pouring the molten liquid copper from a distributing dumping chute (3) towards a ladle (4); (b) connecting the metallic components of the ladle (4) to the ground in order to produce positive charge (17); (c) spraying towards the edge (lip) of the ladle (4) an air jet (19) with dry dusting release agent (20) which is expelled by a nozzle (21) charging the particles of said dry dusting (20) with high voltage and negative charge the particles of said dry dusting release agent (20) with high voltage and negative charge (18); (f) pouring the molten liquid copper (5) from the ladle (4) towards the cavity (II) of a mold (2) of anodes; (g) waiting until the copper gets cold in order to form the anode (6) by means of the turn of the casting wheel (I); (h) driving the ejector rod (13) to expel the anode (6) from the cavity (II) of the mold (2); and (i) removing the anode (6) from the mold (2) by means of cranes. The nozzle (21) is moved over the ladle zone (4) and mold zone (2) by means of a robotic arm (22) which is mounted on a cart (24) suspended above the casting wheel (I).(18); (b) connecting the metallic components of the mold (2) to the ground in order to produce a positive charge (17); (e) spraying towards the cavity (II) of the mold (2) and towards the location zone of the ejector rod (13) dry dusting release agent (20) through an air jet (19) which passes through a nozzle (21) which charges the particles of said dry dusting release agent (20) with high voltage and negative charge (18); (f) pouring the molten liquid copper (5) from the ladle (4) towards the cavity (II) of a mold (2) of anodes; (g) waiting until the copper gets cold in order to form the anode (6) by means of the turn of the casting wheel (I); (h) driving the ejector rod (13) to expel the anode (6) from the cavity (II) of the mold (2); and (i) removing the anode (6) from the mold (2) by means of cranes. The nozzle (21) is moved over the ladle zone (4) and mold zone (2) by means of a robotic arm (22) which is mounted on a cart (24) suspended above the casting wheel (I).
