Abstract
A kind of natural wind fume extractor being mounted on throat, for assisting chimney emission, it include: the vertical smoke exhaust pipe of lower part fastening insertion chimney exhaust, it is located at the outer cover for surrounding smoke exhaust pipe at throat on chimney wall, the lateral wind gathering bucket to connect on outer cover with outer cover barrel chamber, the axial flow blower being mounted in wind gathering bucket, have what is mutually supported ring plate is isolated between outer cover and smoke exhaust pipe, there is wind gathering bucket towards lockplate and locking screw in outer cover lower end, has rubber seal between outer cover lower end and chimney wall.The good effect of the utility model is: being aided with axial flow blower based on natural wind, is formed distinguished and admirable around smoke exhaust pipe outlet, pull the smoke evacuation of chimney breast, reduces the smoke evacuation resistance of flue, raising efficiency of combustion.Help row function big by natural environment wind effect.Electric fan does not contact flue gas, long service life.Structure is simple, convenient for manufacture, installation and maintenance.
Description
Technical field
The utility model belongs to daily (fixed building component) field, and in particular to improves the auxiliary device of chimney emission.
Background technique
Still there are many families or small enterprise's winter are warmed oneself with coal, cook food in northern China, villages and small towns.Due to flame and
Flue gas multithread makes flue lengthen and be obstructed through water-borne heat exchanger.Cause to discharge fume unsmooth.Indoor and outdoor surroundings are polluted, coal stove is reduced
Efficiency of combustion.Electric fan formula air-introduced machine mostly is installed in chimney breast before this, reduces the wind pressure of chimney exhaust, improves smoke evacuation.This
Kind fume extractor, fan blade and motor present position are all in flue gas stream, and seriously corroded, failure increases, and service life is short.This
Before have the device that the distinguished and admirable pulling plume in the same direction with plume is formed by collecting the commutation of part natural wind in throat.But by wind speed shadow
Sound is larger, and calm day loses function.
Utility model content
The purpose of the utility model is to provide a kind of natural wind fume extractors for being mounted on chimney breast, for assisting cigarette
Chimney smoke evacuation, overcomes existing auxiliary fume extractor above shortcomings.
The fume extractor of the utility model includes: the vertical smoke exhaust pipe of lower part fastening insertion chimney exhaust, is located at cigarette
The outer cover of smoke exhaust pipe is surrounded at chimney mouth on chimney wall, the lateral wind gathering bucket to connect on outer cover with outer cover barrel chamber is mounted on wind gathering
Axial flow blower in bucket, there are the gaps for forming pressurization wind cabin between outer cover and smoke exhaust pipe therein, between outer cover and smoke exhaust pipe
There is the form of annular rings bottom plate mutually supported, the upper port of outer cover is higher by smoke exhaust pipe, seals and dock between outer cover and chimney wall upper end.
For the natural wind for making full use of seasonal wind direction, further improving for the utility model is: outer cover lower part or under
End sets ring plate of being isolated between outer cover and smoke exhaust pipe, and ring plate is fixedly connected on outer cover or on smoke exhaust pipe, ring plate as outer cover around
The sliding support of smoke exhaust pipe rotation stretches the wind gathering bucket direction lock of corresponding chimney outlet chimney wall lateral surface in the case where outer cover lower end has
Fixed board assembles wind gathering bucket towards locking screw on lockplate, has rubber seal between outer cover lower end and chimney wall.
The utility model utilizes the hypobaric principle of high flow rate, and distinguished and admirable, reduction smoke exhaust pipe is formed around smoke exhaust pipe outlet
The air pressure of outlet pulls the smoke evacuation of chimney breast, reduces the smoke evacuation resistance of flue, improves efficiency of combustion, reduces having in flue gas
It does harm to object and is polluted to caused by indoor anti-cigarette.This fume extractor is having wind day, and natural wind can meet smoke evacuation and require, calm
It starts axial flow blower, plays the role of auxiliary smoke evacuation.Form the wind-force based on discharging fume with natural wind, supplemented by electronic smoke evacuation.It helps
Row function is small by natural environment wind effect.Electric fan does not contact flue gas, long service life.Structure is simple, convenient for manufacture, installation
And maintenance.
Detailed description of the invention
Fig. 1 is that the utility model is mounted on the front sectional view on chimney.
Specific embodiment
Refering to fig. 1, the fume extractor of the utility model includes: the vertical smoke exhaust pipe 4 that lower part fastening insertion chimney 6 exports,
It is located at the outer cover 3 that smoke exhaust pipe is surrounded on 6 exit chimney wall of chimney, the lateral wind gathering bucket communicated on outer cover 3 with outer cover barrel chamber
1, the axial flow blower 2 being mounted in wind gathering bucket, there are gaps to form pressurization wind cabin 5 between outer cover 3 and smoke exhaust pipe 4 therein, outside
Covering has what is mutually supported ring plate 10 is isolated between 3 lower ends and smoke exhaust pipe 4,10 periphery of ring plate is fixedly connected on outer cover 3.Ring plate 10
Inner hole be slidably matched with smoke exhaust pipe 4, as the sliding support component that outer cover is rotated around smoke exhaust pipe, the upper port of outer cover 3 is higher by
There are rubber seal 9 in smoke exhaust pipe 4,3 lower end of outer cover and chimney wall between 6 upper end.Corresponding chimney 6 is stretched in the case where 3 lower end of outer cover has to go out
For the wind gathering bucket 1 of chimney wall lateral surface towards lockplate 7, that 1 direction of wind gathering bucket is assembled on lockplate 7 holds chimney by top at mouthful
The locking screw 8 of locking.
The present embodiment installation and use process are: the fastening of smoke exhaust pipe 4 being inserted in the outlet of chimney 6, in 6 upper surface of chimney
Put rubber seal.The outer cover 3 for having wind gathering bucket 1 and installing axial flow blower 2 in wind gathering bucket 1 is covered outside smoke exhaust pipe 4, outside
The ring plate 10 of cover lower end is fallen in rubber seal 9.According to the wind direction in installation season, adjust wind gathering bucket 1 direction (in the north,
Autumn, winter, spring, the Xia dynasty were to south by west towards north by west), spin locking screw rod 8 locks outer cover 3.In use, natural wind passes through
Enter wind cabin of pressurizeing, formed and accelerate air-flow upwards, form low pressure in the outlet of smoke exhaust pipe 4 and sweep along air-flow, promotes the flue gas in chimney
It is discharged through smoke exhaust pipe, calm apocalypse moving axis flow fan, auxiliary smoke evacuation.
