Description

Efficient heating-cooking dual-purpose stove

The utility model is a kind of heating-cooking dual-purpose stove.

No. 92224660.2, Chinese patent, name is called " a kind of double water jacket high efficient heating furnace ", and it provides a kind of heating stove of double water jacket, and this heating stove is made up of inside and outside heating water jacket, furnace lining, heat-insulation layer, flue.Its interior heating water jacket is heating water jacket's top outside, by tube connector two heating water jacket's inner chambers is communicated with, and between interior heating water jacket's outer wall and outer heating water jacket's the inwall conducting strip is set, and is equipped with heat absorbing sheet between outer heating water jacket's inwall and the furnace lining.This kind design increases the efficient of heating, but owing to be provided with conducting strip and heat absorbing sheet, it only helps the raising of heat absorption efficiency at the stove use initial stage, but the thing followed is the surface that kerosene slag, cigarette ash etc. are adsorbed on conducting strip and heat absorbing sheet, on the contrary can be unfavorable to absorbing heat, and easy to clean not, make troubles to use, influence result of use.

The purpose of this utility model designs a kind of efficient heating-cooking dual-purpose stove exactly, has both utilized inside and outside double water jacket to improve heat absorption efficiency, and has overcome the deficiency of prior art, and easy cleaning can make full combustion of fuel again.And change the supporting way that has furnace lining, avoid transporting the phenomenon that gets loose in the use.

The purpose of this utility model is achieved by the following scheme.

Efficient heating-cooking dual-purpose stove of the present utility model, it comprises body of heater, furnace lining, heat-insulation layer, thermal insulation layer, inside and outside compound hot water jacket, flue.Furnace lining and furnace lining thermal insulation layer place in the holder tube, on the fire grate, and fire grate places on the right angle buckle that is welded on holder tube lower end, and the upper wall of holder tube links to each other with the support member of water jacket.Open an air inlet in the sidewall of furnace lining thermal insulation layer and the corresponding sidewall of holder tube, air intake passage be in the furnace lining thermal insulation layer radially air inlet be folded to axial passage, the top of axial passage is ring-shaped closed oxygen accumulating chamber, lays through hole on the ring wall of accumulating indoor.Be provided with between burner hearth top water jacket and the bell and suppress fiery device, the bottom outer ring surface of this device and the rotating ring on its top cover all corresponding uniform rectangle annular distance, the interior orifice ring of bottom along on be equipped with fire sealing cover.

Efficient heating-cooking dual-purpose stove of the present utility model is suppressed on the anchor ring of the bottom of fiery device and rotation ring cowling 6 rectangle annular distances is set, and covers in rotating ring and to be symmetrical arranged 3 brace tables.

The efficient heating-cooking dual-purpose stove of the utility model has adopted inside and outside compound heating water jacket, forces even oxygen supply device, and the convenient adjustable fiery device of suppressing makes furnace interior spare all be suspended on hanging structure on the body of heater shell.Therefore dual-purpose stove of the present utility model makes fuel combustion complete, and carbon monoxide is fully utilized, and has improved the utilization rate of coal.Enlarged that the high-temperature region is heated and heat transfer area, increased the heat exchange amount.When the cooking operation, because the oxygen abundance, flame height, firepower are prosperous, have reduced the pollution to environment during burning.The thermal efficiency of this dual-purpose stove is more than 86%, and all parts all are suspended on the body of heater in the stove of the present utility model, have made things convenient for the location between water jacket and furnace lining and body of heater, and has prevented each parts getting loose in transportation and use in the stove.

The utility model description of drawings is as follows.

Fig. 1 is the main cross-sectional schematic of efficient heating-cooking dual-purpose stove.

Fig. 2 is the vertical view of suppressing fiery device of efficient heating-cooking dual-purpose stove.

Below in conjunction with description of drawings embodiment of the present utility model.

Referring to Fig. 1, the efficient heating-cooking dual-purpose stove of the present embodiment; It comprises body of heater 12, furnace lining 6, inner water sleeve 17 and outer water jacket 4, the lower sidewalls of outer water jacket 4 communicates with water return outlet 16, and the lower end of inner water sleeve 17 links to each other with outer water jacket 4 with tube connector, and the top sidewall of inner water sleeve 17 communicates with the top and the delivery port 19 of outer water jacket 4 by tube connector 18, this double water jacket is not provided with conducting strip or heat absorbing sheet, be equipped with rock wool filler heat-insulation layer 8 between body of heater 12 and the outer water jacket 4, the alumina silicate filler thermal insulation layer 7 of furnace lining 6, the bell 3 of flue 1 and body of heater top.The inwall of the body of heater 12 of support angle steel 14 welding of outer water jacket 4 is equipped with steel plate 15 on the angle steel 14, water jacket 4 and heat-insulation layer 8 are supported in steel plate 15 tops, steel plate 15 belows and 9 welding of holder tube.Furnace lining 6 and furnace lining thermal insulation layer 7 place in the holder tube 9, on the fire grate 10, and fire grate 10 places on the right angle buckle 11 that is welded on holder tube 9 lower ends, and angle steel 14, steel plate 15, holder tube 9 and buckle 11 have been formed hanging structure.Sidewall and holder tube 9 corresponding sidewalls in furnace lining thermal insulation layer 7 are opened an air inlet, air intake passage 13 is to be folded to an axial passage by air inlet radially in furnace lining thermal insulation layer 7, the top of axial passage feeds ring-shaped closed oxygen accumulating chamber 5, lay through hole on the 5 inboard ring walls of accumulating chamber, this accumulating chamber 5 is distributed in around the fuel oxygen that enters.
