Fig. 1 is the synoptic diagram of many fuel rings beam-type limekiln of the present utility model.
Fig. 2 is along the sectional view of A-A among Fig. 1.
Fig. 3 is along the sectional view of B-B among Fig. 1.
[embodiment]
See also Figure of description 1 to shown in the accompanying drawing 3, the utility model is a kind of many fuel rings beam-type limekiln, and it mainly is made up of kiln shell 1 and two portions such as inner core 2 of being positioned at kiln shell 1.
Wherein, between described kiln shell 1 and inner core 2, form an annular calcining zone 3, take in Wingdale 6 in this annular calcining zone 3, and Wingdale 6 is calcined.Be provided with upper strata burning beam 4 and lower floor's burning beam 5 in the described annular calcining zone 3, this upper strata burning beam 4 and lower floor's burning beam 5 go to upper and lower two rows and are interspersed.Described upper strata burning beam 4 and lower floor's burning beam 5 extend in the inner core 2 through annular calcining zone 3 edges from the sidewall of kiln shell 1 respectively.Stretch on the upper strata burning beam 4 of annular calcining zone 3 and the lower floor's burning beam 5 and be respectively arranged with some burners (not shown).
