Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
1~Fig. 7 of reference picture, a kind of hot-blast stove, including body of heater and burner 1, the body of heater include furnace chamber, hot air cavity 12,
Flue gas chamber 13 and preheating cavity 14, the hot air cavity 12 are sleeved on outside the furnace chamber, and the flue gas chamber 13 is sleeved on outside hot air cavity 12,
The preheating cavity 14 is sleeved on outside flue gas chamber 13, and combustion chamber 2, upper end and the flue gas chamber 13 of the furnace chamber are provided with the furnace chamber
Upper end is connected, and the lower end of the flue gas chamber 13 is connected with outlet flue 10, and the body of heater also includes waste heat chamber 15, the waste heat chamber 15
Be sleeved on outside the preheating cavity 14, the upper end of the waste heat chamber 15 is connected with cold wind import 7, the lower end of the waste heat chamber 15 with it is pre-
The lower end connection of hot chamber 14, the upper end of the preheating cavity 14 connects with the upper end of hot air cavity 12, the lower end of the hot air cavity 12 and
Hot-blast outlet 5 is connected.
Further, the bottom of the combustion chamber 2 is provided with dismountable shrouding 4.
Further, the upper end of the body of heater is respectively arranged on the left side and the right side hanger 11.
The hot-blast stove also includes electric cabinet 9, and the electric cabinet 9 is connected with the burner 1.
In the present embodiment, the burner 1 is fuel oil or the burner of combustion gas；The bottom of the combustion chamber 2 is provided with opening,
The surrounding of dismountable shrouding 4 is fixed on by hinged bolt in the opening of combustion chamber 2, and the vertical section of the shrouding 4 is
It is inverted T shaped, when needing maintenance etc., this shrouding 4 can be disassembled, then be overhauled.
As shown in Figure 6 and Figure 7, exhaust gases passes 8 include heat smoke main chamber and heat smoke point chamber, and the heat smoke point chamber is set
There are four, four heat smoke point chambers are connected with heat smoke main chamber respectively, and what is walked between two neighboring heat smoke point chamber is hot blast.
The course of work of the present utility model is：
The direction that flows through of flue gas is：Burner 1 produces heat smoke first, and then heat smoke, which is turned left, moves on reflecting plate 3,
Heat smoke is reflexed to the middle part of furnace chamber by the reflection of reflecting plate 3, then heat smoke is distributed to by infundibulate disperser 6
The top of furnace chamber, then heat smoke enters flue gas chamber 13, and is come out by outlet flue 10；
Wind flows through direction：Cold wind enters waste heat chamber from cold wind import 7, subsequently into preheating cavity 14, finally enters hot blast
Chamber 12, cold wind turns into hot blast by the heat exchange with the heat smoke in flue gas layer 13 and furnace chamber, and is come out from hot-blast outlet 5, enters
And carry out various uses.Between waste heat chamber 15 and preheating cavity 14, between flue gas chamber 13 and preheating cavity 14, hot air cavity 12 and flue gas chamber
Heat exchange is carried out between 13, between furnace chamber and hot air cavity 12.
The temperature that the utility model is added on waste heat chamber, preheating cavity shell makes full use of, into the gas temperature of preheating cavity
Degree improves 20 degree or so than in the past, improves the thermal efficiency, has saved the energy.
