A kind of coal dust pottery assembly type burner; Comprise fuel conductor, fuel conductor spout, igniter, bellows, bellows, high-temperature flame-proof pottery powder feeding pipe, the import of high-temperature flame-proof pottery powder feeding pipe, precombustion chamber, swirl vane and taper combustion barrel; The part of said taper combustion barrel is arranged on the inside of bellows; Taper combustion barrel inside is precombustion chamber; The high-temperature flame-proof pottery powder feeding pipe import of high-temperature flame-proof pottery powder feeding pipe is arranged on outside the taper combustion barrel, and the high-temperature flame-proof pottery powder feeding pipe outlet of high-temperature flame-proof pottery powder feeding pipe is arranged in the taper combustion barrel, and high-temperature flame-proof pottery powder feeding pipe outlet end is provided with the backflow cap; Gap location between taper combustion barrel and the bellows is provided with swirl vane; The bellows bottom is provided with bellows, and the fuel conductor spout of fuel conductor stretches in the taper combustion barrel, and fuel conductor spout place is provided with igniter.
Said fuel conductor is connected with tanks.
Said bellows are provided with peep hole and the camera that stretches into the taper combustion barrel.
Said fuel conductor, fuel conductor spout, igniter, bellows, bellows, high-temperature flame-proof pottery powder feeding pipe, the import of high-temperature flame-proof pottery powder feeding pipe, precombustion chamber swirl vane and taper combustion barrel are the combined type demountable structure.
The beneficial effect of the utility model is:
Its structure of the utility model coal dust pottery assembly type burner is a building block system; High-temperature flame-proof pottery powder feeding pipe can anti-1600 deg.c high temperature, high-temperature flame-proof pottery powder feeding pipe guarantees indeformable at 800 degrees centigrade high temperature long-play, and can be according to the different model coal dust; The ceramic burner of production different model; Simultaneously, according to the production needs, can adjust the size and the combustion position of burner at any time.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 is that tanks, 2 is the taper combustion barrel for camera, 15 for peep hole, 14 for swirl vane, 13 for precombustion chamber, 12 for backflow cap, 11 for high-temperature flame-proof pottery powder feeding pipe outlet, 10 for high-temperature flame-proof pottery powder feeding pipe import, 9 for high-temperature flame-proof pottery powder feeding pipe, 8 for bellows, 7 for bellows, 6 for igniter, 5 for fuel conductor spout, 4 for fuel conductor, 3.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Like Fig. 1; A kind of coal dust pottery assembly type burner; Comprise fuel conductor 2, fuel conductor spout 3, igniter 4, bellows 5, bellows 6, high-temperature flame-proof pottery powder feeding pipe 7, high-temperature flame-proof pottery powder feeding pipe import 8, precombustion chamber 11, swirl vane 12 and taper combustion barrel 15; The part of said taper combustion barrel 15 is arranged on the inside of bellows 6, and taper combustion barrel 15 inside are precombustion chamber 11, and the high-temperature flame-proof pottery powder feeding pipe import 8 of high-temperature flame-proof pottery powder feeding pipe 7 is arranged on outside the taper combustion barrel 15; The high-temperature flame-proof pottery powder feeding pipe outlet 9 of high-temperature flame-proof pottery powder feeding pipe 7 is arranged in the taper combustion barrel 15; High-temperature flame-proof pottery powder feeding pipe exports 9 ends and is provided with backflow cap 10, and the gap location between taper combustion barrel 15 and the bellows 6 is provided with swirl vane 12
Bellows 6 bottoms are provided with bellows 5, and the fuel conductor spout 3 of fuel conductor 2 stretches in the taper combustion barrel 15, and fuel conductor spout 3 places are provided with igniter 4.
