Accompanying drawing explanation
Fig. 1 is the structural representation of the micro positive pressure protection device of the utility model rotation electrode powder manufacturing apparatus transmission device chamber.
In figure, 1. transmission device chamber, 2. spray chamber, 3. electrode bar, 4. sealing ring, 5. plasma gun, 6. powder, 7. pressure sensor I, 8. central controller, 9. pressure sensor II, 10. blast pipe, 11. drain taps, 12. air intake valves, 13. air inlet pipe, 14.Ar source of the gas.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The micro positive pressure protection device of the utility model rotation electrode powder manufacturing apparatus transmission device chamber, referring to accompanying drawing 1, comprise central controller 8, spray chamber 2 and the transmission device chamber 1 being connected with spray chamber 2, in spray chamber 2, be provided with pressure sensor I7, in transmission device chamber 1, be provided with pressure sensor II9, pressure sensor I7 is connected with central controller 8 respectively with pressure sensor II9, in transmission device chamber 1, be also provided with air inlet pipe 13 and blast pipe 10, one end that air inlet pipe 13 is stretched out transmission device chamber 2 is connected with Ar source of the gas 14, in air inlet pipe 13, be provided with air intake valve 12 near Ar source of the gas 14 places, one end that blast pipe 10 stretches out transmission device chamber 1 is provided with drain tap 11, air intake valve 12 is connected with central controller 8 respectively with drain tap 11, the junction of spray chamber 2 and transmission device chamber 1 is provided with sealing ring 4.
The operation principle of the micro positive pressure protection device of the utility model rotation electrode powder manufacturing apparatus transmission device chamber: produce plasma arc consumable electrode rod 3 between rotation electrode rod 3 and plasma gun 5 and form powder 6, there is sealing ring 4 transmission device chamber 1 with the junction of spray chamber 2, and rotation electrode rod 3 moves in spray chamber 2 by sealing ring 4 from transmission device chamber 1; Pressure sensor I7 and pressure sensor II9 carry out pressure detection to spray chamber 2 and transmission device chamber 1 respectively, testing result feeds back to central controller 8, in the time that pressure sensor II9 detects that pressure in transmission device chamber 1 is less than pressure sensor I7 and detects that pressure in spray chamber 2 reaches 500Pa, central controller 8 sends instruction unpack valve 12, and the Ar gas in Ar source of the gas 14 enters into transmission device chamber 1 by air inlet pipe 13; In the time that pressure sensor 9 detects that pressure in transmission device chamber 1 is greater than pressure sensor 7 and detects that pressure in spray chamber 2 reaches 500Pa, central controller 8 sends instruction unpack valve 11, and the gas in transmission device chamber 1 is discharged by blast pipe 10.Guarantee that by central controller 8 air pressure in transmission device chamber 1 is greater than the air pressure 500Pa in spray chamber 2; form pressure-fired environment; add like this effect of sealing ring 4, can avoid the powder 6 in spray chamber 2 to enter in transmission device chamber 1, played the protective effect to transmission device.
The micro positive pressure protection device of the utility model rotation electrode powder manufacturing apparatus transmission device chamber; can avoid the powder 6 in spray chamber 2 to enter in transmission device chamber 1; motor, bearing etc. do not touch powder; steadily effective operation to transmission device can play a good protection, and has effectively avoided the generation of accident.
