Therefore, how to solve the problems referred to above, become people's problem demanding prompt solution.
Utility model content
In consideration of it, the purpose of this utility model is to provide a kind of injector for dust arrester, at least to solve in the past
The injection volume that injector exists is little, removes the problems such as dust weak effect.
The technical scheme that this utility model provides, specifically, a kind of injector for dust arrester, it is characterised in that
Including:
Air inducing pipeline 1, is provided with through upper and lower cavity 11 in it；
Annulus line 2, is coaxially disposed with described air inducing pipeline 1, and the fixing company with the upper end sidewall of described air inducing pipeline 1
Connect, described annulus line 2 is provided with the air outlet 21 that the cavity 11 with described air inducing pipeline 1 connects, described
Air inlet 22 it is additionally provided with on annulus line 2.
Preferably, the upper end of described air inducing pipeline 1 is that class is horn-like.
Further preferably, air outlet 21 lower edge of described annulus line 2 and the upper end sidewall of described air inducing pipeline 1 fix one
Body connects.
Further preferably, air outlet 21 upper limb of described annulus line 2 is provided with baffle plate 23, and described baffle plate 23 is with described
Air channel 24 is formed between the upper end sidewall of air inducing pipeline 1.
Further preferably, described air inlet 22 is arranged at the lower section of described annulus line 2, and number is 2.
The injector for dust arrester that this utility model provides, is provided with annulus line in the upper end of air inducing pipeline, and
Annulus line is provided with the air outlet that the cavity with air inducing pipeline connects, by the design of said structure, can realize drawing
The secondary of emitter accelerates drain, specifically, the most a part of compressed gas is entered by the air outlet of annulus line, is drawing
Negative pressure region, the compressed gas then entered, meeting luring at negative pressure region is formed from air inducing pipeline upper end port in wind pipeline
Lead lower generation secondary to accelerate, and then make the compressed gas ejected in injector be accelerated, in jetting pressure and ventilation
Measure identical in the case of, the air velocity ejected by this injector can improve 50～60%, in the impact of high velocity air
Under vibration, it is greatly improved the elimination effect of dust on filter bag, improves injection volume, improve the effect removing dust.
The injector for dust arrester that this utility model provides, has simple in construction, reasonable in design, easy to use,
The advantages such as airflow injection amount is big, and removing dust is effective.
Accompanying drawing explanation
Accompanying drawing herein is merged in description and constitutes the part of this specification, it is shown that meet reality of the present utility model
Execute example, and be used for explaining principle of the present utility model together with description.
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will to embodiment or
In description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that, for ordinary skill people
For Yuan, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the injector for dust arrester；
Fig. 2 is the Fig. 1 sectional view along AA.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is further expalined, but is not limited to this practicality
Novel protection domain.
Little in order to solve the injection volume of conventional injector existence, remove the problems such as dust weak effect, the present embodiment utilizes ring
Shape winding-up principle, it is provided that a kind of injector for dust arrester, sees Fig. 1, Fig. 2, including: it is internally provided with chamber
The air inducing pipeline 1 of body 11, and this cavity 11 runs through the upper and lower of air inducing pipeline 1, at air inducing pipeline 1 co-axially over
It is provided with annulus line 2, and annulus line 2 is fixed with the upper end sidewall of air inducing pipeline 1 and is connected, on annulus line 2
It is provided with air outlet 21 that the cavity 11 with air inducing pipeline 1 connects and for the air inlet 22 connected with compressed gas source,
And air outlet 21 entirety is ringwise, annularly pipeline 2 is circumferentially disposed.
The specifically used method of above-mentioned injector is: respectively by upper port and the air intake of annulus line 2 of air inducing pipeline 1
Mouth 22 connects with compressed gas source, and seeing arrow in Fig. 2 is the flow direction of air-flow, first turns on air inlet 22, will pressure
Contracting gas flows into from the gas outlet 21 of annulus line 2, under the compressed gas impact flowed into, and meeting shape in air inducing pipeline 1
Becoming the negative pressure region of similar cone, be then turned on air inducing pipeline 1 upper port, Partial shrinkage gas flows into from upper port,
After being flowed into air inducing pipeline 1, under the negative pressure region effect formed, can be accelerated by induced compression gas, pass through negative pressure
Compressed gas cognition after region is accelerated ejects from the lower port of air inducing pipeline 1, is ejected into the pre-filter bag being purged dust
On, filter bag is under compressed gas impact at a high speed, it may occur that vibrates and is removed by the dust on filter bag.
As the improvement of technical scheme, see Fig. 2, the upper end of air inducing pipeline 1 is designed as in class horn-like, and annular
Air outlet 21 lower edge of pipeline 2 is fixed as one with the upper end sidewall of air inducing pipeline 1 and is connected, the air outlet of annulus line 2
21 upper limbs are provided with baffle plate 23, form air channel 24 between described baffle plate 23 and the upper end sidewall of air inducing pipeline 1.
Said structure design can improve the acceleration effect to compressed gas and the utilization rate to compressed gas further, by
It is mainly the sidewall of air inducing pipeline in compressed gas being produced deceleration inhibition in the past, and by the design of said structure,
From the compressed gas of annulus line entrance, the sidewall along air inducing pipeline flows into, and can be prevented effectively from the pressure entered from upper port
Contracting gas collides with air inducing pipeline sidewall, flows into the cognition of the compressed gas after air inducing pipeline and directly accelerates to flow out, significantly carries
The high effect removing dust.
As the improvement of technical scheme, see Fig. 1, Fig. 2, be provided with 2 air inlets 22 in the lower section of annulus line 2,
And 2 air inlets 22 are arranged point-blank.
Specific embodiments of the present utility model is to write according to the mode gone forward one by one, and highlights each embodiment
Difference, its similar portion can be with cross-reference.
