DEVICE FOR GAS-THERMAL DETONATION SPRAYING OF COATING LAYER WITH PULSE DOSING OF POWDER FEED Russian patent published in 2018 - IPC B05B7/20 

FIELD: machine engineering.

SUBSTANCE: device for gas-thermal detonation spraying of coating layer with a pulse dosing powder feed contains a body 1, which has a capacity for powder 2 with the powder 3, a distributing disc 4 mounted on the axis 7 with dosing feed cylindrical cavities 5 formed on the peripheral part of the disc 4, a valve 10 with a rod 11, which is connected to a shut-off device 12, a channel 13, connected with a trunk 14, a control unit 15. The disc 4 in the area of the dosing feed cylindrical cavities 5 on each side is provided with a concentric protrusion. The edges of the protrusion are arranged symmetrically with respect to the dosing feed cylindrical cavities 5. The disc 4 is provided with bypass holes 6 arranged around the circumference inside the concentric protrusion of the disc 4. In the body, a curvilinear channel 8 is provided below the disc, the inlet hole of which is located opposite the bypass holes 6, and the outlet hole is located on the same axis with the dosing feed cylindrical cavity 5 and the channel 9, connected with channel 13.

EFFECT: providing the possibility to simplify the dosage and increase its accuracy, compactly distribute the powder in the head of the gas detonating object and reduce its unproductive expenditure, improve the quality of the applied coating, and increase the reliability of the device.
