Description

The dual-purpose type coal stove

The utility model belongs to the moulded coal stove, especially the heating dual-purpose type coal stove of cooking.

At present, the honeycomb briquette hot water heating stove is advanced moulded coal stove, written record heat is imitated and is up to 80%, but still having the part combustible just to be discharged in the environment on every side before fully burning has gone, this not only influences the thermal efficiency and further improves, also contaminated environment, and the waste heat of flue is effectively reclaimed besides, the problem that also has an existence is that the speed of burning is wayward, and this also is a factor that causes energy waste.

The purpose of this utility model just provides a kind of more effective use of energy sources, reduces the moulded coal stove that pollutes.

The purpose of this utility model is achieved like this, recirculated water in its dual-purpose type coal stove heats in three water jackets respectively, at first water heats double the giving in the hot water jacket of body of heater, then, hot water flows into the flue heating pipe again through heating water jacket's tube connector, be subjected to the high temperature heating of heat pipe at last, flow into fin for heating usefulness through the hot water mouth again, its two, the fire sealing cover bottom makes hot room, combustible is fully burnt, reduce to pollute, its three, heat pipe places burner hearth hot room flame jet place, medium can be transmitted to heat rapidly in the flue heating water jacket, its four, strengthen Ventilation Control, adopt natural wind to combine with forced ventilation, forced ventilation is controlled by liquid packing, the adjustable size control.

Owing to adopted three terraced utmost point heat exchange and air quantity control system, make heat conduct more science, efficient further improves, and the combustible burning is more abundant, and energy utilization rate is higher, has also reduced pollutant emission.

Set forth the technical solution of the utility model in more detail below in conjunction with accompanying drawing, Fig. 1 is that the utility model is the A-A face cutaway view of Fig. 4, and Fig. 2 is the front view of liquid packing, and Fig. 3 is its vertical view, and Fig. 4 is a vertical view of the present utility model.

Be the sequence number explanation of each parts among each figure below:

1, give the hot water jacket tube connector, 2, chimney gives hot-water line, and 3, heating water jacket's pipe, 4, water return outlet, 5, liquid packing, 6, water, 7, the high wind inlet, 8, the high wind pipe, 9, the natural wind hole, 10, the ash door, 11, furnace bottom, 12, hold grey chamber, 13, fire grate, 14, the double hot water jacket that gives of body of heater, 15, secondary ventilating ducting, 16, furnace lining, 17, internal furnace, 18, the colector ring heating water jacket that holds concurrently, 19, outer burner hearth, 20, fire sealing cover, 21, bell, 22, hot room, 23, heat pipe, 24, flue box, 25, the flue heating water jacket, 26, hot water outlet, 27, chimney, 28, the envelope gas hood, 29, the pond, 30, ventilation duct, 31, the filler, 32, valve.

In Fig. 1, the water cyclic part is such: the water in the dual-purpose type coal stove water jacket, in three water jackets, heat respectively, at first water is in the body of heater bottom and locates burner hearth (19) and flue and give in the hot water jacket (2) and heating double the giving of body of heater in the hot water jacket (14), giving hot water flows into fire-collected ring and holds concurrently in the heating water jacket (6) through giving hot water tube connector (1), be subjected to flame vertically to roast heating, water temperature raises rapidly.Secondary is subjected to hot water to flow into flue heating water jacket (25) again through adding hot water tube connector (3), is subjected to the high temperature heating of heat pipe (23) once more, flows into fin through hot water mouth (26) again.

One, the structure of fire sealing cover (20) is such: its underpart makes hot room (22), room temperature can reach 850～1050 degree during burner hearth moulded coal normal combustion, when in internal furnace (17), sufficient air feed being arranged, the high temperature unburning material can burn in the flame, and the low temperature unburning material will mix with the secondary air feed flow into that hot room (17) is subjected to behind the high temperature can completing combustion, efficiently utilize the energy, reduced pollution.

Two, heat pipe (23) is made with seamless pipe, the flat length that crouches is less than 1/3rd of total pipe range, angle is full of medium and partly is placed on burner hearth hot room (22) flame jet place greater than 45 degree between the person in charge and the lying pipe in the pipe, and medium will pass to heat rapidly in the flue heating water jacket (25).

Three, air quantity control system.This dual-purpose type coal stove adopts gravity-flow ventilation and two kinds of draft types of forced ventilation; 1, natural wind, a. natural ventilation hole (9) can be regulated by trace.B. the ash double air door of door (10) adopts rock wool blanket bolted press seal, the adjusting nature air quantity that startup can be relatively large when not starting.2, forced ventilation, when burner hearth needs a large amount of air feed, will obturage earlier gravity-flow ventilation road (9) and (10), start hair-dryer then, high wind through liquid packing (5), hold grey chamber (12), fire grate (8) enters burner hearth, another transportation work style can make the burner hearth combustion flame peak in secondary air duct enters internal furnace (17).Otherwise, the hair-dryer outage, liquid packing (5) cuts off forced draft duct, enables the gravity-flow ventilation road, realizes that burning is controlled.

Four, the structure of liquid packing and principle are such: in the case of a sealing, a upper end open tubular metal pond (29) is housed, as Fig. 2, shown in Figure 3, lower end, pond (29) has the pipeline of a band valve (32) to lead to outside the case, the upper end of pipe is filler (31), ventilation duct (30) is in the pond, and communicate with the outside by high wind inlet (7), go up face shield at ventilation duct (30) and an envelope gas hood (28), the water tumbler that envelope gas hood (28) as same back-off, some exhaust vents (33) are arranged on the edge, its underpart, when high wind enters the mouth (7) when being blown into from high wind, seal gas hood (28) and from the pond, float, what air did not stop passes through from exhaust vent (33), suitable for reading through the pond, after entering into tube connector (8) again, enter and participate in burning in the burner hearth (17), and after blower fan stops, envelope gas hood (28) borrows deadweight to fall in the pond (29), seals the current return circuit of air.

Fire sealing cover (20) is circular, and the centre accompanies refractory material, and two ends are metal material, and following hot room (22) is formed for several concentric drums, and the inner lane place of being higher than circle is step to be arranged, and has numerous circular holes to gang up mutually on the tube.

This ventilating system can make the moulded coal in the burner hearth burn 3.5-4 hour time, also can be in the time internal combustion that reaches 65-70 hour.

This dual-purpose type coal stove has compact conformation and reason, and the characteristics that the thermal efficiency is high are applicable to family and unit Use.
