Abstract
The utility model discloses an improved fuel gas reversing type energy-saving maintaining furnace. The furnace comprises a furnace body, a panel of the upper end of the furnace body, and a furnace core. The lower part f the furnace body is internally provided with an ash box. One side of the outer wall of the furnace body is provided with a smoke pipe. The lower end of the furnace body is connected with a heat insulated box. A gap is reserved between the outer wall of the furnace core and the inner wall of the furnace body. A via hole is arranged in the body of the heat insulated box in the lower end of the gap. A main smoke gas outlet channel is arranged on the furnace body above the port of the furnace core, communicated with the upper part of the smoke pipe, and internally provided with a separation plate which can be rotated to close off the main smoke gas outlet channel. An auxiliary smoke gas outlet channel is arranged in the lower part of the smoke pipe and communicated with the heat insulated box. In this way, the heat generated by burning of coal can be fully absorbed and the secondary utilization of heat energy can be achieved, thereby realizing energy saving and environment protection. At the same time, the beautifulness of the maintaining furnace as a whole is ensured; the materials are saved; and the production procedures are reduced.
Description
Technical field
The utility model relates to a kind of flue gas reversion type energy-saving heat preserving stove, particularly a kind of improved flue gas reversion type energy-saving heat preserving stove.
Background technology
Coal-fired heating furnace type of the prior art is many, the thermal current that coal combustion produces is after chimney is discharged, furnace gas pressure reduces, the cold air of outside constantly enters combustion chamber in a steady stream, the oxygen of input continues to support coal combustion, reaches the object of insulation, because the flue gas that fire coal produces is directly taken away by the smoke pipe of combustion chamber upper end, thermal loss is large, not energy-conservation.Chinese patent: CN202973183U discloses a kind of flue gas reversion type energy-saving heat preserving stove, comprise shaft, the panel of shaft upper end and combustion chamber, ash bin is set in restoration of lower stack, be connected with incubator in shaft lower end, on the shaft body above combustion chamber port, be provided with exhanst gas outlet passage, exhanst gas outlet passage is connected main smoke pipe, in exhanst gas outlet passage, be provided with rotatable dividing plate, also be provided with secondary smoke pipe outward at shaft, secondary smoke pipe upper port is connected the exhanst gas outlet passage before dividing plate, the lower port of secondary smoke pipe connects incubator, incubator is also connected with main smoke pipe.
The heat that above-mentioned patent the has solved coal-fired generation problem of being fully used, but find through practice, the secondary smoke pipe arranging shaft outside is seen not attractive in appearance from entirety, the while is also wasted material, also increases production process.
Summary of the invention
For the deficiencies in the prior art, the utility model aims to provide a kind of flue gas reversion type energy-saving heat preserving stove, under the hot flue gas prerequisite that fully circulation, heat are fully used in holding furnace of guaranteeing to produce at fire coal, also guarantees holding furnace overall appearance, save material, reduce production process.
For solving the problems of the technologies described above, the technical solution of the utility model: a kind of flue gas reversion type energy-saving heat preserving stove that improves, comprise shaft, the panel of shaft upper end and combustion chamber, ash bin is set in restoration of lower stack, in shaft outer wall one side, smoke pipe is set, be connected with incubator in shaft lower end, gapped between the outer wall of combustion chamber and shaft inwall, on the incubator body of lower end, gap, be provided with through hole, on the shaft body above combustion chamber port, be provided with flue gas primary outlet passage, flue gas primary outlet passage is connected smoke pipe top, in flue gas primary outlet passage, be provided with can rotary closing flue gas primary outlet passage dividing plate, smoke pipe bottom arranges the auxiliary exit passageway of flue gas, the auxiliary exit passageway of flue gas is connected incubator.
Adopt this energy-conservation holding furnace, fire coal is in combustion chamber after burning, and high-temperature flue gas both can directly enter smoke pipe from flue gas primary outlet passage drains, and flue gas also can enter smoke pipe from auxiliary exit passageway; When with this holding furnace frying food, can open the dividing plate in flue gas primary outlet passage, the intensity of a fire is at upper shaft; In the time that this holding furnace is used for warming oneself, can close the dividing plate in flue gas primary outlet passage, gap between combustion gas furnace outer core and shaft housing enters incubator, and in incubator, after circulation, flue gas enters smoke pipe by auxiliary exit passageway again and drains, the heat of flue gas is fully absorbed like this, reach the secondary utilization of heat energy, because ash bin is arranged on restoration of lower stack, when coal-fired, can suitably open ash bin, oxygen directly enters combustion chamber from grate, is beneficial to the abundant burning of coal.
The utility model is simple in structure, and heat utilization rate is high, and energy-conserving and environment-protective also guarantee holding furnace overall appearance simultaneously, saves material, reduces production process.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In accompanying drawing: movable bell 11 grate 12 gap 13 through holes of 1 shaft 2 panel 3 incubator main smoke pipe 6 primary outlet passage auxiliary exit passageway 9 ash bin 10 of 7 dividing plate 8 of 4 combustion chamber 5.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, what shaft 1 upper end arranged is panel 2, the centre of panel 2 is movable bells 10, is combustion chamber 4 in shaft 1, and combustion chamber 4 use refractory materials are made, the grate of combustion chamber 4 arranges ash bin 9 11 times, grate 11 upper spaces of combustion chamber 4 are used for filling fire coal, and with respect to other combustion chambers, the height of grate 11 upper spaces of this combustion chamber 4 is lower, coaling so few, be convenient to coal and fully burn, shaft 1 lower end connects incubator 3, shaft 1 is supported on incubator 3, and incubator 3 is square casing, between the outer wall of combustion chamber 4 and shaft 1 inner walls gapped 12, on incubator 3 bodies of 12 lower ends, gap, be provided with through hole 13, flue gas can enter incubator 3 by gap 12 and through hole 13, in shaft 1 outer wall one side, smoke pipe 5 is set, on shaft 1 body above combustion chamber 4 ports, be provided with flue gas primary outlet passage 6, flue gas primary outlet passage 6 is connected smoke pipe 5, in flue gas primary outlet passage 6, be provided with rotatable dividing plate 7, in the time that dividing plate 7 rotations are extremely axial perpendicular to flue gas primary outlet passage 6, flue gas primary outlet passage 6 is closed, in smoke pipe 5 bottoms, auxiliary exit passageway 8 is set, auxiliary exit passageway 8 is connected incubator 3, like this, when the dividing plate 7 of closing in flue gas primary outlet passage, flue gas enters incubator 3 from the gap 12 between furnace core outer wall and shaft housing, after the interior circulation of incubator 3, flue gas enters smoke pipe 5 by auxiliary exit passageway 8 again and drains.
