Description
Technical field
It the utility model is related to a kind of dust hood, more particularly to a kind of blowing-extracting type dust hood.
Background technology
In smelting iron and steel, material heating process, a large amount of airborne dusts can be produced, it is necessary to which a kind of dust hood is sent into dedusting after absorbing
Device purifies.During smelting operation, comprising charging, discharge process, it is desirable to fire door top（Airborne dust point）Open wide, side can only be set
Dust hood is high plus dusty gas temperature so that the dusty gas rate of climb is fast, to its whole is collected into dust hood,
Suction air volume must be just increased, increases cost.
For existing side dust hood described above under the conditions of high speed airborne dust, suction air volume is big, the big deficiency of cost of investment.
With regard to the high speed airborne dust the characteristics of and for the operation principle of air-suction cover, the direction of motion of forcibly changing airborne dust air-flow, reduces purification institute
The suction air volume needed, is all the innovative point place of the utility model.
Utility model content
To sum up, for various deficiencies existing in the prior art, the utility model is intended to develop a kind of blowing-extracting type dust hood,
By increase circulate blast pass, the direction of motion of forcibly changing airborne dust air-flow, the position of reasonable Arrangement suspended hood, reach with compared with
Few processing air quantity, realizes the clean-up effect to high speed airborne dust.
To reach above-mentioned effect, the utility model uses following technical scheme：
A kind of blowing-extracting type dust hood, including circulation air hose and exhaust duct, one end of the circulation air hose and the row of exhaust duct
Air port is connected with suspended hood together, circulates and booster fan is provided with the other end of air hose, is connected on the air outlet of booster fan
There is an ejiction opening, injection mouth is oppositely arranged with suspended hood and is blown the blowing direction of mouth towards suspended hood.
In the above-mentioned technical solutions, the relative position of the injection mouth and suspended hood is not in same level.
In the above-mentioned technical solutions, horizontal level of the horizontal level of the suspended hood higher than injection mouth.
In the above-mentioned technical solutions, the injection mouth is flat.
In the above-mentioned technical solutions, the injection mouth is flat for horizontal direction.
In the above-mentioned technical solutions, the both sides that mouth is each located on airborne dust air-flow with suspended hood are blown.
During work, booster fan is opened so that circulating current is laterally blown out at a high speed by being blown mouth, against suspended hood,
During this, it will be located between injection mouth and suspended hood, the airborne dust air-flow forced moved upwards at a high speed changes into laterally side on the upper side
Moved to against suspended hood, the mixed airflow of suspended hood blowing in future mouthpiece and airborne dust point absorbs rear portion and arranged by exhaust duct
Remove, another part completes circulation after booster fan pressurizes by circulating air hose again by injection mouth blowout.To protect
Air draught effect is demonstrate,proved, the circulated air of injection mouth blowout must cover whole rising airborne dust air-flow.In addition, in order to ensure air draught effect,
And reduce the temperature of mixed airflow, it is also necessary to the extraneous clean cold wind of suction part.Meanwhile air circulation is adjustable.
To sum up, it is using the beneficial effect of the utility model blowing-extracting type dust hood：
1）For the feed bin of opened upper end, under conditions of needing to reserve Job Operations space on top, cannot covering, pass through
Injection mouth at a high speed is provided opposite in suspended hood, forcibly changing rises the direction of motion of airborne dust air-flow, it is smoothly entered air draught
Cover, you can air draught total amount during airborne dust is handled to reduce, and the air draft total amount for needing to purify can be reduced, with less investment and fortune
Row expense, realizes the effect of no airborne dust.
2）Due to the mechanical periodicity of airborne dust throughput, required suction air volume is also different, can be by adjusting circulation at any time
The size of air quantity and injection wind speed, is optimal effect.
Brief description of the drawings
Fig. 1 is the structural profile illustration of the utility model blowing-extracting type dust hood.
Embodiment
In order to be more clearly understood the advantages of making the purpose of this utility model and technical solution, below in conjunction with attached drawing and reality
Example, is further elaborated the utility model.
The utility model is described in detail with reference to attached drawing, a kind of blowing-extracting type dust hood, its structure mainly includes：Spray
Mouthpiece 1；Suspended hood 2；Exhaust duct 3；Circulate air hose 4；Booster fan 5 and other connection adjusting apparatus.The injection mouth 1 is by steel
The air outlet of the given shape of plate composition；Air outlet is provided opposite to suspended hood 2, and size, the shape of the suspended hood are bases
The actual conditions design of airborne dust air-flow.Exhaust duct 3 is provided with suspended hood, the exhaust duct 3 is connected with purifying dust-removing device
Connect, circulation air hose 4 is provided with exhaust duct 3 or suspended hood 2, the other end of the circulation air hose is connected to booster fan 5
Air inlet, the air outlet of booster fan 5 is connected to injection mouth.
During work, booster fan 5 is opened so that circulating current 11 is by being blown mouth 1, and against suspended hood 2, laterally blowout is high
Fast blast pass 6, will be located between injection mouth 1 and suspended hood 2, the airborne dust air-flow 8 that the high speed produced by airborne dust point 7 is moved upwards
Forcibly changing is the mixed airflow 9 in laterally direction on the upper side, is moved against suspended hood 2, suspended hood blowing in 2 future mouthpiece and airborne dust point
Mixed airflow 9 absorb rear portion and excluded by exhaust duct 3, another part passes through booster fan 5 by circulating air hose 4
Blown out after pressurization again by injection mouth 1, complete circulation.To ensure air draught effect, the high speed blast pass 6 that injection mouth 1 is blown out
Whole rising airborne dust air-flow 8 must be covered.In addition, in order to ensure air draught effect, and reduce the temperature of mixed airflow, it is also necessary to
The extraneous clean cold wind of suction part.Meanwhile air circulation 11 is adjustable.
Bright spot of the utility model without the open feeding warehouse of airborne dust includes：
1）By being provided opposite to injection mouth at a high speed in suspended hood, forcibly changing rises the direction of motion of airborne dust air-flow, makes
It smoothly enters suspended hood, you can air draught total amount during airborne dust is handled to reduce, and can reduce the air draft total amount for needing to purify, is used
Less investment and operating cost, realize the effect of no airborne dust.
2）Due to the mechanical periodicity of airborne dust throughput, required suction air volume is also different, can be by adjusting circulation at any time
The size of air quantity and injection wind speed, is optimal effect.
More than, be only the utility model preferable embodiment, but the scope of protection of the utility model and more than that, times
What those familiar with the art the change that can readily occur in or replaces in the technical scope that the utility model discloses
Change, should be covered within the scope of the utility model, therefore, the scope of protection of the utility model should be with claim
