DEVICE FOR APPLICATION OF COATINGS FROM DISPERSED MATERIALS Russian patent published in 2003 - IPC

FIELD: equipment for application of coatings; applicable, particularly, for application of protective coatings by spraying of dispersed materials in electrostatic conditions. SUBSTANCE: device body accommodates ejector mixer in form of hollow bushing with through holes. Installed in bushing cavity is ejector for axial motion. Ejector is integral piece in form of two cylinders interconnected by connector. Each cylinder and connector have through hole. Located in body cavity on opposite side of handle is voltage multiplier whose first inlet output serves as grounding output, and outlet output is connected to high-voltage electrode. The second inlet output of voltage multiplier is connected to high- voltage source whose inlet output serves as output for connection to power supply unit. Switch is made in form of push button and connected to power supply circuit by means of electric switch and to pneumatic switch in form of piston valve. High voltage source may be provided with indicator brought out to body surface. Handle is made for grounding by means of contact. Power supply unit is grounded by means of grounding busbar. EFFECT: reduced overall dimensions of device, higher its maneuverability and dustproofness, provided direct control of supplied powder. 2 dwg
