Abstract

The utility model relates to a positive-counter heating high-efficiency heating stove which is composed of a heat exchanging water jacket, a stove body, a stove top cover, heat insulating materials, an upper and a lower flues, etc. The utility model is characterized in that the heat exchanging water jacket is composed of a water jacket for a stove chamber, a water jacket for the flues and a water jacket for a chimney; a plurality of transverse water pipes are welded in the middle of the water jacket for the stove chamber to form a water-cooling grate which divides the stove chamber into an upper and a lower stove chambers which are communicated with a vertical flue in the water jacket for the chimney through the upper and the lower flues, and an upper and a lower flue baffle plates are arranged in the upper and the lower flues. When used for firing or cooking, the utility model adopts a positive heating mode, the upper flue baffle plate is opened, and the lower flue baffle plate is closed; when used for heating, the utility model adopts a counter heating mode, the upper flue baffle plate is closed, and the lower flue baffle plate is opened.

Description

Positive and negative burning high efficient heating furnace

The utility model belongs to the domestic heating device, relates to a kind of positive and negative burning high efficient heating furnace.

The domestic heating stove has hundreds of item patent, but be mostly the mode of just burning, there is over-emitting black exhaust, efficient is low, shortcomings such as it is bad to cook, in order to overcome above-mentioned shortcoming, there are recent years several patents to propose positive and negative burning mode, as a kind of positive and negative burning dual-purpose stove (patent No. 90219242), positive and negative burning bidirectional multifunctional cooking stove (patent No. 91201942), inversed fire suppressed type heating-cooking dual-purpose stove (patent No. 92244854) etc., preceding binomial patent lacks practicality owing on the structure, and has abandoned patent right, a back patent, do not establish chimney water sleeve from structure, the pyrotechnics flow process is short, only is fit to burn anthracite, and the thermal efficiency is low when burning bituminous coal.

Task of the present utility model provides a kind of perfect performance, positive and negative burning heating stove structure easy to use, and chimney water sleeve is set, lengthening pyrotechnics flow process, increase heating surface, improve the thermal efficiency of domestic heating stove the biglyyest, and don't the influence cook, release the positive and negative burning high efficient heating furnace of a kind of new construction.

Major technique of the present utility model is characterised in that: positive and negative burning high efficient heating furnace is made up of heat exchanging water-jacket, body of heater, furnace top cover, fire grate, ash bucket, insulation material, last lower flue, and the heat exchanging water-jacket is made up of hearth water sleeve, flue water jacket, chimney water sleeve; Be welded with some horizontal water tubes in the centre of hearth water sleeve inner core and constitute water-cooled grate, burner hearth is divided into lower hearth; Upper furnace communicates by the top of the vertical gas pass in upper flue and the chimney water sleeve, and lower hearth communicates by the bottom of lower flue and vertical gas pass, is provided with damper up and down in last lower flue; The hearth water sleeve upper end links by cross over pipe and chimney water sleeve top, and the lower end links by flue water jacket and chimney water sleeve bottom; Circumferentially be welded with some heat absorptions in the lower hearth inner core upper edge of hearth water sleeve and help sheet; On the inner core of chimney water sleeve, be welded with the several layers sway bracing pipe.

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is the structural representation of positive and negative burning high efficient heating furnace

Fig. 2 is the AOA cutaway view of Fig. 1

The positive and negative burning high efficient heating furnace of Fig. 1, Fig. 2, description, it is made up of heat exchanging water-jacket (1), body of heater (2), furnace top cover (30), fire grate (9), ash bucket (10), insulation material (38), stove pin (11), upper flue (33), lower flue (44).

Concrete structure is described below: heat exchanging water-jacket (1) is made up of hearth water sleeve (40), flue water jacket (15), chimney water sleeve (22), and hearth water sleeve (40) is made of garden type inner core (4) and urceolus (3); Be welded with some horizontal water tubes (5) at the middle part of inner core (4) and constitute water-cooled grate (41), burner hearth is divided into upper furnace (42) and lower hearth (43); Circumferentially be welded with some heat absorptions in inner core (4) upper edge of lower hearth water jacket and help sheet (12), fin (12) is the lath of high 20～30mm, have window (6) in its side and fire door (7) communicates, symmetry has window (14) and lower flue (44) communicates, and is provided with damper (18) in the outlet of lower flue (44); Flue water jacket (15) is made of inner core (16) and urceolus (17), by inner core (16) and urceolus (17) hearth water sleeve (40) and chimney water sleeve (22) welding are linked, chimney water sleeve (22) is made of inner core (23) and urceolus (24), form vertical gas pass (39) by inner core (23), on inner core (23), be welded with several layers sway bracing pipe (21), every layer of sway bracing pipe (21) arranged crosswise; Be provided with cross over pipe (37) in hearth water sleeve (40) upper end and chimney water sleeve (22) communicates, on chimney water sleeve (22), be provided with water outlet ozzle (25), be provided with backwater ozzle (20) in the lower end, be provided with movable closure plate (19) in vertical gas pass (39) lower end; Fill insulant material (38) between hearth water sleeve (40) and body of heater (2), on upper furnace water jacket inner core (4), ward off refractory cement (36), be to constitute the chamber of a kitchen range (35) on upper furnace (42) by furnace top cover (30) and chamber of a kitchen range body (29), have window (32) in its side and upper flue (33) communicates, and communicate by flue tube (26) and vertical gas pass 39, on flue tube (26), be provided with damper (27), on furnace top cover (39), be provided with kitchen range mouth (28), which is provided with bell (31), have stockhole (34) at the end at chamber of a kitchen range body (29); Heat exchanging water-jacket (1) supports and is fixed in the body of heater (2) by the supporting plate (8) that is welded on the body of heater (2), and supporting plate (8) has fire grate (9), is grey thorax (13) under it, in establish ash bucket (10).
