Description
Technical field
This utility model is related to a kind of draught fan for boiler, belongs to boiler plant technical field.
Background technology
Boiler is a kind of energy conversion, and the energy to boiler input has chemical energy in fuel, electric energy, and boiler exports
There is steam, high-temperature water or the organic heat carrier of certain heat energy.The original meaning of pot refers to the water container of heating on fire, and stove refers to burn
The place of fuel, boiler includes pot and stove two large divisions.In boiler, the hot water producing or steam can be directly commercial production and people
Heat energy needed for people's livelihood offer alive, also can be converted to mechanical energy by Steam Power Equipment, or be turned mechanical energy by electromotor
It is changed to electric energy.The boiler providing hot water is referred to as hot-water boiler, is mainly used in living, and also has a small amount of application in commercial production.Produce
The boiler of steam is referred to as steam boiler, is often simply called boiler, is used for thermal power station, ship, locomotive and industrial and mining establishment.Either heat
Homogeneous solution-type reactor or steam boiler, basic structural unit is all to produce heat energy by the fuel combustion in stove the water in pot to be carried out add
Heat heats up.The passage that oven body part is usually provided with combustor and connects combustor, the high-temperature gas producing after fuel combustion
Outwards derived by passage, passage is often provided within pot part and carries out heat exchange, makes the flue gas cool-down discharged by chimney,
The water making pot partly interior is heated up.Draught fan for boiler is usually mounted on boiler chimney, plays and draws wind action, but passes
The air-introduced machine of system only has a kind of function of air inducing, can not play a role in filtering for boiler smoke, therefore the dust in flue gas
Also need to other devices to reclaim.
Utility model content
Therefore, the purpose of this utility model is to overcome defect of the prior art, provide a kind of can be in flue gas
The draught fan for boiler that dust is reclaimed.
To achieve these goals, a kind of draught fan for boiler of the present utility model, including the cylinder being vertically arranged, in institute
State the top of cylinder and be provided with smoke-intake pipe in tangential direction, described smoke-intake pipe is communicated in described inner barrel；Described
Coaxially it is provided with pipe, the top of described pipe extends to the outside at described cylinder top in cylinder；Described smoke
The part in described cylinder of pipe, periphery wall is provided with the fan fin that coiling extends；The top peace of described pipe
Equipped with belt pulley, described belt pulley is used for connecting to motor by belt, drives described pipe rotation by motor.
It is fixed with aerofoil fan fin inside the pipe on the top of described pipe.
The bottom of described cylinder is taper, and its diameter is in reduction trend from top to bottom.
The lower section of described cylinder is provided with disposal box.
Using technique scheme, draught fan for boiler of the present utility model, pulley rotation is driven by motor, thus
So that pipe is rotated, when the fan fin on pipe periphery wall rotates, produce wind-force, wind-force drives the flue dust in smoke-intake pipe to enter
Enter in cylinder and be rotated into row cyclone dust removal in cylinder, dust falls to disposal box, flue gas is then risen by pipe discharges,
Reach the effect of dedusting.Draught fan for boiler of the present utility model, takes into account dedusting function while realizing air inducing, and structure is tight
Gather, good dedusting effect.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
As illustrated, the present embodiment provides a kind of draught fan for boiler, including the cylinder 1 being vertically arranged, in described cylinder 1
Top and be located at tangential direction on be provided with smoke-intake pipe 2, described smoke-intake pipe 2 is communicated in inside described cylinder 1；In described cylinder
Coaxially it is provided with pipe 3, the top of described pipe 3 extends to the outside at described cylinder 1 top in 1；Described smoke
The part in described cylinder 1 of pipe 3, periphery wall is provided with the fan fin 4 that coiling extends；Described pipe 3 upper
Portion is provided with belt pulley 5, and described belt pulley 5 is used for connecting to motor (not shown) by belt, drives institute by motor
State pipe 3 to rotate.
It is fixed with aerofoil fan fin 6, the companion of described aerofoil fan fin 6 inside the pipe on the top of described pipe 3
Pipe 3 together rotates and discharges the flue gas in pipe 3.
The bottom of described cylinder 1 is taper, and its diameter is in reduction trend from top to bottom.
The lower section of described cylinder 1 is provided with disposal box 7.
Using technique scheme, draught fan for boiler of the present utility model, pulley rotation is driven by motor, thus
So that pipe is rotated, when the fan fin on pipe periphery wall rotates, produce wind-force, wind-force drives the flue dust in smoke-intake pipe to enter
Enter in cylinder and be rotated into row cyclone dust removal in cylinder, dust falls to disposal box, flue gas is then risen by pipe discharges,
Reach the effect of dedusting.Draught fan for boiler of the present utility model, takes into account dedusting function while realizing air inducing, and structure is tight
Gather, good dedusting effect.
Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.For
Change or the change of other multi-forms for those of ordinary skill in the art, can also be made on the basis of the above description
Dynamic.There is no need to be exhaustive to all of embodiment.And the obvious change thus extended out or change
Among the dynamic protection domain created still in this utility model.
