Description

The air blast down-draft kiln

The utility model is about a kind of stove, more particularly about a kind of air blast down-draft kiln.

In the prior art, stove generally all is vertical and horizontal, but no matter is vertical or horizontal stove, and its flame generally is up, and promptly hot blast from lower to upper.The stove and accessory of this structure is extremely appropriate for using as civilian or steel plant in general occasion, but then is unfavorable for the preparation of some special occasions such as bronze mirror.

The purpose of this utility model is to provide a kind of air blast down-draft kiln, and this air blast down-draft kiln is suitable especially and in the preparation bronze mirror.

These and other objects of the present utility model will embody further by following detailed.

Down-draft kiln of the present utility model comprises body of heater, bell, air inlet, fire bars, upper air duct, pad brick, lower air duct, chimney and partition wall, and flame enters burner hearth by upper air duct during burning, comes out to enter chimney from lower air duct then.

Down-draft kiln of the present utility model is said so from top to bottom especially because the tendency of flame is different from general stove, the therefore just suitable especially bronze mirror etc. of making.And owing to adopted unique design, therefore, the bronze mirror that bakes out is not broken not to be split, and has embodied the original demeanour of ancient bronze mirror admirably.

Below further embody and the utility model be described by accompanying drawing and explanation thereof.

Fig. 1 is a cutaway view of the present utility model.

In Fig. 1, symbol 1 is represented body of heater, and symbol 2 is represented bell, and symbol 3 is represented air inlet, and symbol 4 is represented fire bars, and symbol 5 is represented upper air duct, symbol 6 representative pad bricks, and symbol 7 is represented lower air duct, and symbol 8 is represented chimney, and symbol 9 is represented partition wall, and symbol 10 is represented furnace chamber.

In the utility model, air inlet 3 is in the lower end of fire bars 4, and air inlet can be garden shape or other shape, and fire bars can be placed fuel with becoming the sort of of palisade in the prior art on the fire bars.Fire bars can be extracted out from body of heater or two ends directly are fixed on the upper end of partition wall 9, and its shape can be square, rectangle or garden shape (not shown), and upper air duct 5 is in the upper end of partition wall 9, and pad brick 6 is placed in the lower end of body of heater 1, places the article of firing on the pad brick 6; Lower air duct 7 is at the lower-left of chimney 8 end, and communicates the same upper air duct of its shape with furnace chamber 10; Another bell 2 is arranged on furnace chamber 10.

In use, at first open bell 2, the object that adds fuel (as timber) respectively and need fire, cover bell 2 then, igniting, air blast, fuel combustion, flame enters furnace chamber 10 from upper air duct 5, and as shown in Figure 1, flame passes furnace chamber, in furnace chamber 10, flame becomes downdraf, and the object that roasting need be fired comes out to enter chimney 8 from lower air duct 7 then and discharges in the kiln.
