Description

Boiler tube formula high efficiency energy-saving domestic hot water heating stove

The utility model belongs to solid-fuelled domestic burners, specifically is a kind of boiler tube formula domestic hot water heating stove.

Existing domestic hot water's heating stove adopts mostly the ring-type water jacket is set between body of heater and burner hearth, and interior dress heating water is connected to form hot water circuit by delivery port, water return outlet and heating pipe, radiator; Usually being welded with fin, V-arrangement wing, arc wing etc. on the water jacket inwall above the stockhole cooperates with Air return ring, stockhole top is provided with insulation cover, force the heat of stockhole to turn round after through fin, V-arrangement wing or arc wing heating water jacket to improve the thermal efficiency of heating stove.China's utility model patent discloses a kind of adjustable return air, arc wing, internal heat type heating stove for No. 93223341.4, water jacket is improved be divided into two parts up and down, and top is bigger than lower part diameter; Hot wing cooperates with deflector in adopting, Air return ring cooperates with the arc wing, insulation cover cooperates with Air return ring, and making radiation, convection current, conduction, heat exchange is one, further improves the thermal efficiency.The heating water jackets such as interior hot wing, arc wing but the heat of stockhole still needs to turn round, thereby still exist the lower defective of the thermal efficiency.

The purpose of this utility model provides a kind of high efficiency energy-saving domestic hot water heating stove, further improves the thermal efficiency of heating stove.

For achieving the above object, technical solution of the present utility model is: a kind of boiler tube formula high efficiency energy-saving domestic hot water heating stove, comprise smoke-box, flue, water jacket, delivery port, water return outlet, body of heater, fire door, burner hearth, fire grate, heat-insulation layer, it is characterized in that: it is 0～60 ° boiler tube that the inboard of stockhole top, water jacket is welded with some and horizontal plane angle, and hot water can circulate in water jacket and boiler tube.

In the such scheme, have the body of heater door greater than the burner hearth vertical section on the body of heater, burner hearth is fixed on the inboard relevant position of body of heater door, and burner hearth is in the center of body of heater substantially when the body of heater door is closed.The groove of the oriented under shed in position that the bottom of water jacket is corresponding with the body of heater door, groove top is higher than stockhole, and width is greater than the external diameter of burner hearth, and the bottom of boiler tube is higher than the top of groove.

In the such scheme, corrugated can be made in the inboard of water jacket.

In the such scheme, water jacket, boiler tube are welded by general steel plate, steel pipe or other sheet material, tubing heat-resisting, corrosion-resistant, that readily conduct heat.Can be parallel to each other between the many boiler tubes, also certain angle can be arranged, but between the boiler tube certain clearance should be arranged, the fuel in the burner hearth can fully be burnt.

Because in the utility model, the interior hand hay cutter of water jacket is welded with some boiler tubes, be located immediately at the city, high-temperature region directly over the stockhole, be a heat exchanging piece efficiently; After corrugated is made in the inboard of water jacket, increase the surface area that water jacket is heated, thereby the utlity model has the high advantage of the thermal efficiency.And the utility model is simple in structure, be easy to make, cost is low.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1, Fig. 2 are respectively the front views of the utility model embodiment one, embodiment two.

Fig. 3 is that the A of Fig. 1, Fig. 2 is to cutaway view.

Fig. 4 is that the B of Fig. 2 is to cutaway view.

Fig. 5 is the stereogram of water jacket 3 among Fig. 2.

Embodiment is just like Fig. 1, shown in Figure 3: water jacket 3 usefulness steel plates are welded into the ring-type of cavity, contain heating water in the cavity, and the upper and lower has delivery port 4 and is connected with heating pipe with water return outlet 5; The inboard of water jacket 3 is a corrugated, and the steel pipe of middle part (refer to up and down) two 1 inch diameters of parallel welding is as 17, two boiler tubes of boiler tube, 17 spacing 25mm, with horizontal plane angle be 5 °, heating water can flow freely in boiler tube 17 and water jacket 3.Present embodiment is suitable for the less lump coal of combustion volume, coal etc. looses.During use, pour water in heating pipe, water jacket 3 and the boiler tube 17, coal from the gap of boiler tube 17 is slagged tap from fire door 7.The heat directly-fired kiln pipe 17 of stockhole after 2 one-tenth coal smokes of smoke-box 1, flue discharge.

Embodiment two is as Fig. 2, Fig. 5, shown in Figure 4: water jacket 3 is with the water jacket of embodiment one, but a groove 19 under shed is arranged at the bottom, the top of groove 19 is higher than stockhole, width is greater than the external diameter of burner hearth 8, the boiler tube 17 spacing 15mm of three 6 fens diameters, the bottom of boiler tube 17 is higher than the top of groove 19.Have the body of heater door 14 corresponding on the body of heater 6 with groove 19 positions.Fire grate is arranged at burner hearth 8 bottoms, and bracket 9, the bottom bracket 10 made with steel bar are fixed on burner hearth 8 on the body of heater door 14, between body of heater door 14, body of heater 6 and the burner hearth 8 heat-insulation layer 16 are housed, and body of heater door 14 is connected with body of heater 6 by hinge 15.The present embodiment monoblock fuel such as honeycomb briquette that are suitable for burning in the time of need changing coal and slag tap, are opened hooked hand's handle 12, are held handle 13 and can draw back body of heater door 14, and at this moment burner hearth 8 shifts out in body of heater 6, can advance coal, slag tap.Close body of heater door 14, door hooked hand handle 12 insertion doors collude and can make body of heater doors 14 fixing in 11.
