Abstract

Provided is a chimney opening smoke ejector. The chimney opening smoke ejector is installed on a smoke outlet of a chimney, prevents national wind which is not beneficial for ejecting smoke from disturbing smoke ejecting, and maintains cleanness of indoor air and personal safety. The chimney opening smoke ejector is composed of a vertical shaft which is arranged above a chimney outlet and on a centre line position of the chimney, a wind direction shaft which is installed on the vertical shaft through a bearing, a windward arc-shaped board which is fixed at one end of the wind direction shaft and can cover the chimney outlet and power-driven induced draft fan, and a following wind directional board which is fixed at the other end of the wind direction shaft. The chimney opening smoke ejector has the advantages that the windward arc-shaped board prevents wind which blows to the ground in an inclined mode from pouring into the chimney, enables the wind to pass by two sides of the windward arc-shaped board, speeds up flow rate, reduces pressure, reduces resistance of smoke when the smoke outflows the chimney outlet, and creates conditions for speeding up discharging the smoke. The power-driven induced draft fan is used for discharging cool air in a chimney flue, the power supply of the power-driven induced draft fan can be turned off, the chimney can completely rely on the chimney opening smoke ejector to eject the smoke continuously and smoothly, service life of an inducted draft fan is greatly prolonged, and electric energy consumed by continuous operation of the inducted draft fan is saved.

Description

The throat smoke ejector

Technical field

The invention belongs to the combustion fuel technical field of heating, be specifically related to eliminate in family's cooking and the heating the not smooth device of chimney emission during combustion fuel.

Background technology

At present, in rural area and small town, resident's cooking and heating are still take burning coal, faggot as main.Because being not suitable for building the chimney stack of similar factories and miness technically with on the economic capability, so the smoke evacuation ability is lower, often make the anti-cigarette of cooking stove because of the wind-force of unfavorable smoke evacuation, the impact of wind direction, people even cause anthracemia chokes.Although the electronic air-introduced machine that is installed on the throat had been arranged in the last few years, eliminated the generally speaking not smooth problem of chimney emission, but in the strong wind sky, when particularly earthward wind appears tiltedly blowing in the throat place, depend merely on air-introduced machine and can't overcome chimney and fall the phenomenon of cigarette.

Summary of the invention

The purpose of this invention is to provide a kind of throat smoke ejector, be installed on the exhaust opening of chimney, prevent from being unfavorable for that the natural wind of discharging fume is to the interference of smoke evacuation, the cleaning and the personal safety that keep room air.

Throat smoke ejector of the present invention is by being positioned at chimney breast top and at the vertical shaft of chimney position of center line, be installed in wind direction axle on the vertical shaft by bearing, be fixed on wind direction axle one end, laterally can shelter from the arc plate that facings the wind of throat and electronic air-introduced machine, the with the wind position plate that is fixed on the wind direction axle other end forms.

Good effect of the present invention is: the arc plate resistance of facining the wind has been ended the wind of tiltedly blowing earthward and has poured into chimney impact smoke evacuation, make simultaneously the wind at the throat place that flows through kept off by the arc plate resistance, force it to pass through along arc plate both sides, accelerated flow velocity, reduced pressure, strengthen the pressure reduction of the throat gas peripheral with it, reduced the resistance that smoke gas flow goes out throat, created condition for accelerating smoke evacuation.Use the smoke ejector that helps of the present invention, only need the air-introduced machine at operation throat place in 3-5 minute after the kitchen range top or stove and accessory igniting, behind the cold air of discharging by air-introduced machine in the flue, can close fan power, make by smoke ejector of the present invention fully that chimney continues, smooth and easy smoke evacuation, greatly prolonged the air-introduced machine useful life, saved air-introduced machine and moved continuously the electric energy that consumes.

Fig. 2 is top view of the present invention.

The specific embodiment

Consult accompanying drawing, the present invention includes the vertical shaft 2 on the rain cover that is installed in the electronic air-introduced machine 1 in throat place, be installed in wind direction axle 4 on the vertical shaft by bearing 3, the face of cylinder that be fixed on an end of wind direction axle 4, laterally can shelter from throat and the electronic air-introduced machine arc plate 5 that facings the wind is fixed on the with the wind position plate 6 of the wind direction axle other end.Bearing 3 wherein uses rain and snow, anti-sootiness, anti-freeze bearing.

Claims

1. throat smoke ejector, it is characterized in that: this smoke ejector is by being positioned at chimney breast top and at the vertical shaft of chimney position of center line, be installed in wind direction axle on the vertical shaft by bearing, be fixed on wind direction axle one end, laterally can shelter from the arc plate that facings the wind of throat and electronic air-introduced machine, the with the wind position plate that is fixed on the wind direction axle other end forms.
