Abstract
The utility model relates to a crucible pot furnace leg with pore channels at the inner part. The utility model is characterized in that an air inducing channel and a smoke discharging channel are converged in the furnace leg to solve the technical problem how the auxiliary secondary air of an unpowered smoke-eliminating and energy-saving crucible pot furnace can be induced into a hearth, and simultaneously, the smoke and the fire in the hearth can be effectively discharged into fire sucking holes of a furnace disk. The utility model can lead the structure of a furnace to be more compact, can simplify the masonry of furnace walls, and can ease the labor intensity of workers to change cylinders.
Description
The present invention relates to a kind of coal reducing crucible furnace (kiln) leg, establish the reducing crucible furnace (kiln) leg in duct in particularly.
The stove leg of this known class pot furnace, its duct are to be used for waste gas in the kiln burner hearth and pyrotechnics are used this road discharge burner hearth, enter stone or metal plate for standing a stove on as a precaution against fire and inhale fire hole, and be smoke evacuation formula stove leg.It in constructional feature be the inlet of smokejack in the both sides of stove leg, and outlet is in the outside of stove leg, corresponding the suction fire hole of stone or metal plate for standing a stove on as a precaution against fire.
At present, in order to solve of the pollution of kiln flue dust, the Chinese invention patent of having applied for " fume-eliminating energy-saving pot furnace " (application number: 99105313.3) proposed and transformed conventional pot furnace, under motorless condition to atmosphere, to assist secondary wind and introduce burner hearth, mix the technical scheme of burning smoke dirt.Therefore, how will assist secondary wind and introduce burner hearth, be to implement this to invent problem to be solved.
The objective of the invention is: improve the stove leg of above-mentioned pot furnace, wind channel is set, the auxiliary smoke abatement and dust control that realizes kiln.
The stove leg of this induced air type pot furnace can be the all-in-one oven leg of sinter molding, but preferred plan is combined type stove leg.Combined type stove leg is built by laying bricks or stones by the shaped brick stack of several different sizes and shape and is formed, and wherein establishes the basic shaped brick in duct in the stove leg bottom, has constituted induced air type reducing crucible furnace (kiln) leg of the present invention.For easy to make, this basic shaped brick can be split type, and it is involuted by two identical duct bricks, and the middle section in basic shaped brick horizontal component duct, involutory back is the faying face of duct brick.
Now, technical solution of the present invention is described in conjunction with the embodiment of Figure of description.
Fig. 1 is that the axle of induced air type reducing crucible furnace (kiln) leg duct brick is surveyed schematic diagram.
The duct brick of stove leg of the present invention is provided with smokejack and wind channel.
The wind channel of duct brick is made of air inducing docking port (1), main air duct (2), branch air channel (3) and air outlet (4).
Air inducing docking port (1) also is the bottom of stove leg in the bottom of brick body.Main air duct (2) is the duct of one section rising, and it can be a vertical lifting, also can be oblique rising, its function is except carrying auxilliary secondary wind, and can be lifted out air port (4), and make air outlet certain height be arranged apart from stone or metal plate for standing a stove on as a precaution against fire, enter stove leg wind channel to avoid crucible to leak material.Branch air channel (3) be with auxilliary secondary air separating to the both sides of stove leg, enter burner hearth, their horizontal axis can coexist on the straight line, but preferred plan is; Two axis become the obtuse angle, and to stove leg outer incline, so that during air-out, the outer fluid (pyrotechnics and waste gas) of the flow direction that makes auxilliary secondary wind and stove leg forms in the same way and collaborates, and is beneficial to the smoke evacuation of burner hearth.Air outlet (4) is in the both sides of (stove leg) duct brick.
The smokejack of duct brick by smoking port (5), flue (6), and smoke evacuation docking port (7) constitute.
Smoking port (5) is in (stove leg) brick both sides, duct, and smoke evacuation docking port (7) is in (stove leg) duct brick bottom.
The utility model adopts the advantage of such scheme to be: use the stove leg and solved the problem that kiln smoke elimination air inducing advances burner hearth.In addition, wind channel and smokejack collect in the same stove leg, make the structure of this type of kiln compact more, simplified building by laying bricks or stones of kiln wall, when also having avoided using the conventional oven leg because the residue of seat clay and refractory material, regular scatters, and the sintering alluvial has alleviated the labour intensity of workman in changing the cylinder operation near stone or metal plate for standing a stove on as a precaution against fire and suction fire hole.
Such scheme also can separate the wind channel of stove leg basis shaped brick in actual applications with smokejack, make and only establish wind channel in the stove leg, at chorista smokejack is set partly, combine when kiln is built by laying bricks or stones, or as conventional kiln, smokejack and kiln wall are built by laying bricks or stones with the refractory brick material temporarily.Need to prove: the stove leg that smokejack and wind channel unite two into one only is applicable to and inhales the kiln type of fire hole before the stove leg.If inhale fire hole before crucible, basic shaped brick only need be provided with wind channel.
In addition, in the formation of wind channel, also can cancel main air duct (2) in the shaped brick of stove leg of the present invention basis, make the branch air channel be positioned at stove leg bottom and be open type, at this moment, basic shaped brick is the duct brick, and it need not two.When kiln is built by laying bricks or stones, the branch air channel of open type is assisted in the outlet of secondary wind being buckled in stone or metal plate for standing a stove on as a precaution against fire, form the air inducing docking port of a stealth.In like manner, the smokejack of stove leg, also method in view of the above forms the smoke evacuation docking port of a stealth.Adopt this scheme, need to increase the size of duct vertical sectional height, leaked the material obstruction by the residue of refractory material and crucible to avoid the duct.
With reference to Figure of description in detail, enforcement of the present invention is described in detail.
In the kiln build, during the masonry heater leg, elder generation is docked at the air inducing docking port and smoke evacuation docking port of first stove leg duct brick in the auxilliary secondary wind outlet and suction fire hole of stone or metal plate for standing a stove on as a precaution against fire.Second stove leg duct brick make-up stack built by laying bricks or stones on first stove leg duct brick, thereafter, other stove leg shaped brick is built by laying bricks or stones successively, form the stove leg of induced air type pot furnace.
