INSTALLATION FOR SPRAYING OF THE GAS-THERMAL COATINGS Russian patent published in 2006 - IPC C23C4/12 C23C4/18 B05B7/22 B01F7/04 

FIELD: mechanical engineering; installations for spraying of the plasma gas-thermal coatings.

SUBSTANCE: the invention is pertaining to the field of mechanical engineering, in particular, to the installation for spraying of the plasma gas-thermal coatings and may be used for deposition of metallic, metal-ceramic and ceramic coatings by spraying onto a surface at manufacture and restoration of the details of the different configuration. The installation contains: the heat-sound-insulation chamber, the circular plate, the plasmatron holder, the plasmatron, the plasma generator, the shotblasting gun and the hopper. The circular plate with a hole in its middle is mounted horizontally with a possibility of rotation around of the vertical axis. On it and coaxially to it there is an installed workpiece. The circular plate through its central hole is connected to the hopper having two chambers: the central chamber and the peripheral chamber. The chambers are partitioned from each other by the separation mesh. The central chamber of the hopper has the conical bottom with the collector. The peripheral ring-shaped chamber is connected to the air duct. The technical result of the invention ensures: the possibility for keeping the workpiece of the complex configuration and the big mass on the circular plate without fastening, because due to its big mass it reliably stands on the circular plate; significant simplification of the plasmatron feeding and fixation of all the communications to the plasmatron, as compared with on their horizontal feeding.

EFFECT: the invention ensures the possibility for keeping the workpiece of the complex configuration and the big mass on the circular plate without fastening, its reliable standing on the circular plate, significant simplification of the plasmatron feeding and the all communications fixation to the plasmatron, as compared with the horizontal feeding.
