Abstract

The utility model belongs to an energy-saving multipurpose heating stove. A pipe type fire sealing heat exchanging method is formed by upper and lower annular water sleeves connected with a plurality of vertical pipes, a fire sealing tray and a fire dividing slice. The utility model is also provided with a secondary air pipe which is extended to the stove bottom space. Compared with a common fire sealing heat exchange stove, the stove of the utility model has the advantages of simple structure and low manufacture cost. The heat efficiency can reach more than 85%. The utility model is suitable for heating at stores, schools, offices, green houses and families. The utility model can also be doubled as a living stove for supplying hot water and cooking food.

Description

Pipe type stove

The utility model belongs to a kind of stove and accessory, particularly a kind of energy-saving heating multipurpose furnace.

The utility model is a kind of improvement of fire-depressed type Heating stove, the fire-depressed type Heating stove has thermal efficiency height, and area of heat-supply service is big, and the volume of corresponding stove and accessory is the obvious advantage such as 1/2 grade of other stove and accessory of same specification, but common fire-depressed type Range structure is complicated, and processing cost is higher.

The purpose of this utility model provides a kind of simple in structure, and the processing and manufacturing cost is lower, has more given prominence to a kind of tubular type of fire-depressed type Heating stove characteristics and has suppressed fiery warming stove.

The technical solution of the utility model is: tubular type is suppressed fiery warming stove by base (1), shell (15), insulating layer of furnace body (14), burner hearth heat-insulation layer (5), ash bucket (2), tile (17), fire bars (3), flue (8) and delivery port (7), water return outlet (4) is formed, its the annular lower water jacket (18) that communicates with water return outlet (4) is located in the burner hearth heat-insulation layer (5) of body of heater waist, the top of annular lower water jacket (18) is communicated with annular upper water sleeve (12) by some standpipes (17), the top of standpipe (18) exposes fully in burner hearth, leave the slit between the outer of annular upper water sleeve (12) and insulating layer of furnace body (14) or the inner lining of furnace (13), on the insulating layer of furnace body (14) or inner lining of furnace (13) on annular upper water sleeve (12), be fixed with the fire-suppress disk (10) that has some fire seperating pieces (9), some fire seperating pieces (9) evenly distribute and be fixed on fire-suppress disk (10) below, the center of annular upper water sleeve (12) is provided with fire-suppressing cover (19), in burner hearth heat-insulation layer (5), be embedded with secondary air channel (21), its lower end extends the space of bottom of furnace body, and the air inlet of upper end (20) is located in the burner hearth.

Further specify the technical program with drawings and Examples below:

Fig. 1 is the utility model structural profile schematic diagram;

Fig. 2 is a fire seperating piece installation site schematic diagram;

Fig. 3 is a secondary air channel installation site schematic diagram;

As shown in Figure 1, annular lower water jacket (18) is located in the burner hearth heat-insulation layer (5) of body of heater waist, and communicate with the water return outlet (4) at body of heater rear portion, 14 standpipes (16) around tile (17) with on the annular ' lower water jacket (12) (18) is communicated with, the lower part of standpipe (16) places in the refractory cement of burner hearth heat-insulation layer (5), top exposes fully in burner hearth, between shell (15) and the inner lining of furnace (13) by the rock wool filling, leave 2 centimeters slits between annular upper water sleeve (12) and the inner lining of furnace (13), inner lining of furnace (13) on annular upper water sleeve (12) is gone up the fire-suppress disk (10) that welding has 5 fire seperating pieces (9), fire seperating piece (9) is welded on below the fire-suppress disk, the installation site as shown in Figure 2, the space above flue (8) and the fire-suppress disk (10) is communicated with.

Annular upper water sleeve (12) center is a fire door, when covering fire-suppressing cover (19), the flow direction of the hot flue gas of burner hearth inevitable earlier through the slit between 14 standpipes (16), the slit between annular upper water sleeve (12) and inner lining of furnace (13) again, and be subjected to the flow-dividing control of 5 fire seperating pieces (9), after reenter flue (8).

Among Fig. 1, (1) be base, (3) for fire bars, (2) for ash bucket, (6) for connect the ash tube, (7) are bell for delivery port, (11) that communicate with annular upper water sleeve (12).

Fig. 3 illustrates two secondary air channels (21) and is embedded in the burner hearth heat-insulation layer (5), so that secondary wind is realized giving heat, secondary air channel (21) passes annular lower water jacket (18), the upper end is welded on annular upper water sleeve (12) bottom, have overfiren air port (20) in the burner hearth inboard, the lower end is located at ash bucket (2) body of heater lower space in addition, and two secondary air channels (21) distribute around tile (17) symmetrically with 14 standpipes (16).Said single-unit furnace can constitute the disjunctor stove as lower water jacket (12) (18) on flue (8), the annular is communicated with in the present embodiment.

The utility model has the advantages that:

1. because the effect of fire-suppress disk, fire seperating piece, fire-suppressing cover, make all directly the be heated barbecue of flue gas of riser upper, the whole surface of annular upper water sleeve, so heat exchange area is bigger, heat exchange efficiency takes full advantage of thermal source up to 85%.

2. annular upper and lower water jacket is communicated with by standpipe, has increased the ratio tolerance of water in the water jacket, has increased the circulation power of hot water.

3. secondary air channel places in the burner hearth heat-insulation layer, make secondary wind before entering burner hearth through giving heat, make coal-fired fully burning, reduced the imperfect combustion product, not only energy-conservation as CO etc., the security that has improved coal stove again.

4. the design simplifies the fire-depressed type Range structure, and the processing and manufacturing cost is low.
