A coating system operations vehicle. Related methods are provided for filling a tank and operating coating equipment on a vehicle. The methods include pumping coating from containers into a tank on the vehicle and dispensing the coating for application on a surface. A method also includes removing residual coating from the containers after pumping out coating and adding the residual coating material to the tank. If the level of coating is at the desired level in the tank, a layer of water may be formed over the coating in the tank.

A fluid dispenser, comprising a dispenser faceplate having at least one ejection port and a dispenser guard. The dispenser guard has at least one opening configured to allow fluid exiting from the ejection port to flow through and at least one drainage structure. The dispenser guard is spaced from the ejection port with a gap small enough to attract the fluid accumulated around the ejection port to flow into the drainage structure.

A coating booth (101) for elements to be coated. The coating booth (101) comprises a passage between opposing vertical sides (107a, 107b, 108a, 108b) through which elements to be coated are conveyed. There is an entrance (105) at one end of the passage and an exit (106) at the other end of the passage. The coating booth (101) comprises a conveyor line (102) for supporting said elements to be coated and configured to convey said elements from the entrance (105) to the exit (106) along a straight pathway, and, a suction system. The opposing sides of the channel are symmetrical about the pathway. Sets of spray guns (103a, 104a, 103b, 104b) for spraying coating powder at the elements are positioned symmetrically either side of the straight pathway. The suction system comprises vertical suction inlets (109a, 109b) mounted opposite one another on each opposing vertical side of the passage, the suction system being configured to provide equal amounts of suction through each of the opposing vertical suction inlets (109a, 109b).

A dispensing device includes a dispensing mechanism and a calibration mechanism coupled to the dispensing mechanism. The calibration mechanism includes a control unit. The control unit is configured to detect a position difference between a dispensing needle and a reference coordinate in a direction. The dispensing mechanism is configured to adjust the dispensing needle in the direction according to the position difference.

An apparatus for performing liquid treatment for a substrate is provided. The apparatus for performing the liquid treatment for the substrate may include a housing having a treatment space, a substrate support unit to support and rotate the substrate in the treatment space, a liquid feeding unit including a nozzle device including a central exhaust port and multiple first outer exhaust ports, which are provided in a shape of a ring to form a concentric circle with the central exhaust port to feed mutually different treating liquids onto the substrate through respective exhaust ports, and a controller to control the liquid feeding unit.

A process and system for cleaning a high pressure separator vessel in a polymerization reactor without removing the top cover and its associated bolts by providing a cleaning hole in a fluid fitting above and adjacent to the top cover, through which a cord or cable is fed and affixed to a rotatable cleaning nozzle. The cleaning nozzle is gradually raised, lowered and rotated to direct a high pressure liquid onto the interior walls of the vessel to remove accumulated waste material.

A cleaning device for use with an atomizer that applies paint to the surface of a component in a spray booth includes an external and internal surface in which a least a portion of one or more of the surfaces are coated with a conductive coating. This conductive coating comprises one or more fluoropolymers and may be static dissipative. The cleaning device further includes an exit port that has an aperture between about 2.54-7.62 cm located in the shroud of the device opposite the opening that receives the atomizer and near a bottom corner of the shroud. A kit used to retrofit existing paint spraying systems includes a fully assembled cleaning device and optionally, a regulator assembly capable of reducing the pressure of a cleaning fluid to about 80 psi. During installation, the regulator assembly is mounted external to the spray booth.
