The specific embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
Embodiment one: as shown in Figure 1, a kind of domestic biomass combustion furnace, comprise the body of heater 1 with air chamber 2, and the flue 3 of the air chamber 2 interior arrangements of body of heater 1 and the bell 4 on the body of heater 1, the loam cake of described flue 3 outstanding bodies of heater 1 suitable for reading, also comprise blower fan 5, described blower fan 5 is air chamber 2 air-supplies of body of heater 1 by the fan wind inleting tube 6 of body of heater 1 bottom, described flue 3 is arranged in the air chamber 2 of body of heater 1 by support 7, and the bottom surface of flue 3 bottom surfaces and described air chamber 2 does not join, the bottom surface of described flue 3 is provided with the main wind pushing hole 8 that communicates with described air chamber 2, described support 7 is round table-like network structure, its bottom surface is conflicted on the bottom surface of described air chamber 2, its connected mode can be to be tightly connected with screw, it also can be other connection, described flue 3 is placed in the upper bottom surface of this support 7, its connected mode can be that screw connects, it also can be other connection, air chamber 2 bottom surfaces in the present embodiment are rounded, the bottom surface of above-mentioned support 7 is also rounded, and its radius equates with air chamber 2 bottom surface radiuses, and support 7 just can tightly be installed on the bottom surface of air chamber 2 like this.Described body of heater 1 has an air chamber 2, the present embodiment is blown into air by the blower fan 5 of body of heater 1 bottom in air chamber 2, by the main wind pushing hole 8 of flue 3 bottom surfaces air is sent in the flue 3 again, can effectively guarantee the amount of oxygen in the flue 3, promote the abundant burning of its fuel, the problem of avoiding cigarette greatly and easily extinguishing.
Described flue 3 inside are divided into the fuel region of bottom and the flame zone of top, fuel region, described flue 3 side wall upper part are provided with the spiral spiral wind of inwall hole 9 and the wind hole 10 of charging, the described wind hole 10 of charging is positioned at the flame zone of flue 3, and described spiral wind hole 9 is positioned at the top in the above-mentioned wind hole 10 of charging.During use, blower fan 5 is blown into air to air chamber 2, flue 3 fuels constantly burning cause air minimizing in it, air is except entering the flue 3 from main wind pushing hole 8, remaining is then entered by charge wind hole 10 and spiral wind hole 9, the consumption large quantity of air because flue 3 fuels constantly burn, and main wind pushing hole 8 needs just can rise to flame zone behind the fuel region, for fuel combustion and flame output, but it can not satisfy flame zone far away to the demand of air, air in the air chamber 2 then can enter flame zone fast by the wind hole 10 of charging, the formation shape of charging, carry air to flame zone rapidly, it both can provide fuel combustion necessary air to flame zone, flame upwards can be transferred out flue 3 again; Another part air of air chamber 2 then enters flue 3 by spiral wind hole 9, because of the inwall in spiral wind hole 9 in the shape of a spiral, air can form eddy current after it enters flue 3, strengthened flowability, not only provides again burning required air for it, promoted especially flowing of flue 3 interior air and flame, flue 3 interior air and flame are fully stirred, make air more even with burning, flue 3 fuel combustion get more abundant, and flame is more prosperous, exports higher.
Described bell 4 is tapered, its top be tubular fire the cylinder 17, cylinder 17 the sidewall that fires is provided with induced draft hole 12, fire the cylinder 17 inside be provided with crater 18, when flue 3 fuels in when burning, air just can reduce gradually in it, and the air of bell 4 outsides is then because the effect of negative pressure enters the flame zone of the cylinder 17 that fires through above-mentioned induced draft hole 12.The internal diameter of crater 18 is less than the internal diameter of fan wind inleting tube 6, therefore can be in flue 3 mineralization pressure, flue 3 interior temperature are raise.The utility model through main wind pushing hole 8, spiral wind hole 9, the repeatedly air distribution such as wind hole 10 and induced draft hole 12 of charging, impel flue 3 interior temperature risings and fuel combustion to get more abundant with 18 pairs of flues of crater, the 3 interior pressure that can form, firepower is powerful, make its fuel produce Pintsch process, fuel is fully burnt, can reach the effects such as energy-efficient, smokeless and dust free, low-carbon environment-friendly.And bell 4 is designed to taper, compares with common bell, and its outlet is less, and the height of flame ejection and the temperature of flame then can be higher, and firepower is more powerful.
In addition, be insulation and the safe effect that strengthens this combustion furnace, be provided with heat-insulation layer 11 in the bottom surface of body of heater 1 inwall and/or flue 3 outer walls and/or air chamber 2.
This combustion furnace burns by charging in advance, and less expensive is fit to be widely used.
Embodiment two: as shown in Figure 2, the combustion furnace of the present embodiment also comprises to the feed mechanism of flue 3 interior transfer the fuels, described feed mechanism is made of loading hopper 13, the conveyance conduit 14 and the propulsive mechanism that communicate with flue 3, and described propulsive mechanism is the spiral propeller 16 that is arranged in the conveyance conduit 14 and is driven by motor 15.All the other structures of the present embodiment are identical with embodiment one.
By feed mechanism flue 3 fuels are sprung up reinforcedly, need not to charge in advance at every turn, especially applicable downdraft burning, i.e. from top to bottom burning, and cigarette is few, has increased the adaptation of product, it is practical to be worth highlyer, and use more should be widely promoted.
The above, it only is the utility model preferred embodiment, therefore can not limit the scope that the utility model is implemented with this, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
