Abstract
The invention discloses a kind of dustproof filter mouth, including filter tip body, the front of filter tip body is provided with air inlet, up with the side of the front vertical it is provided with gas outlet, the back side of filter tip body is provided with the interface being connected with air sampling rig entrance and the outgassing column being connected with air sampling rig outlet, wherein, interface is connected with air inlet, and outgassing column is connected with gas outlet.By carry out gas collecting air inlet and collection after the gas outlet that is exhausted be vertically arranged through row so that the gas of entrance does not block outlet side, more effectively meets curstomer's site use, improves the accuracy and practicality of detection.
Description
Technical field
The invention belongs to air sampling rig field, and in particular to a kind of dustproof filter mouth.
Background technology
With science and technology and the continuous improvement developed rapidly with living standards of the people of industry, manner of breathing is ceased with people's daily life
The air quality problems of pass are also increasingly subject to people's attention, and suspend aerial solid or liquid particles thing, to people and
Other biological health can work the mischief, and air pollution and have become great focus in the world, therefore, city to its environmental monitoring
A feast for the eyes air sampler transition joint is occurred in that on field, while the dustproof filter mode of sampler is varied, collection
Efficiency is different.
Various filter tip service efficiencies are different, are therefore unable to reach more higher leveled accuracy in control accuracy, also because
This, is present than larger measure error to sampled result, and it is inaccurate that this allows for environmental monitoring results.
Content of the invention
For drawbacks described above or deficiency, it is an object of the invention to provide a kind of rational in infrastructure, sampling is accurate, monitoring efficiency
High dustproof filter mouth.
For reaching object above, the technical scheme is that：
Including filter tip body, the front of filter tip body is provided with air inlet, up with the side of the front vertical
Gas outlet is provided with, the back side of filter tip body is provided with the interface and and air being connected with air sampling rig entrance
The outgassing column that sampling apparatus outlet is connected, wherein, interface is connected with air inlet, and outgassing column is connected with gas outlet.
Seal groove is provided with the interface, and seal groove is engaged by sealing ring sealing with air sampling rig entrance.
The front of the filter tip body is offered for carrying out the groove of surface dust.
The root of the outgassing column is provided with the O-ring for sealing.
Be diverging pagoda shape inside the air inlet, and the dust-proof cotton for filtering is placed with along pagoda shape cavity wall.
It is provided with the middle part of the filter tip body for being fixed the through hole of installation.
Compared with the prior art, beneficial effects of the present invention are：
The invention provides a kind of dustproof filter mouth, by carry out gas collecting air inlet and collection after be exhausted
Gas outlet is vertically arranged so that the gas of entrance does not block outlet side, is more effectively met curstomer's site use, is improve
The accuracy and practicality of detection.In addition, the present invention is arranged at the back side of filter tip body being connected with air sampling rig outlet
The outgassing column for connecing, is so that outgassing column is closely connected with air sampling rig outlet, improves the sealing of collecting device, improve
The acquisition precision of device and collecting efficiency.
Further, the present invention opens up two through holes in filter tip body, is fastened by crossed pan head screw, convenient dismounting
With assembling.
Description of the drawings
Fig. 1 is that the filter structure of the present invention illustrates Fig. 1；
Fig. 2 is that the filter structure of the present invention illustrates Fig. 2；
Fig. 3 is the filter tip knot side view of the present invention.
In figure, 1 is filter tip body, and 2 is air inlet, and 3 is gas outlet, and 4 is interface, and 5 is outgassing column, and 6 is seal groove, 7
For groove.
Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in detail.
As Figure 1-3, the invention provides a kind of dustproof filter mouth, including filter tip body 1, filter tip body 1
Front is provided with air inlet 2, is just provided with gas outlet 3 towards vertical side is up with described, and the back side of filter tip body 1 sets
The interface 4 being connected with air sampling rig entrance and the outgassing column 5 being connected with air sampling rig outlet is equipped with, its
In, interface 4 is connected with air inlet 2, and outgassing column 5 is connected with gas outlet 3.Air inlet is vertical with the final direction in gas outlet, keeps away
The problems such as outlet obstruction, inconvenience is exempted from.The front of the filter tip body 1 is offered for carrying out the groove 7 of surface dust.This
Filter tip in invention for being molded, surface cloudy surface process, it is therefore an objective to dust how many whiles above dust-proof cotton can be seen,
The structure of housing filter tip draw-in groove is not seen.
Filter tip lower end devises radial seal mode, is provided with seal groove 6 on the interface 4, and seal groove 6 is adopted with air
Sampling device entrance is by sealing ring sealing engaging so that air inlet reaches sealing effectiveness；The root of the outgassing column 5 is provided with use
O-ring in sealing.
Further, in order to improve accuracy of detection, it is to avoid collect other impurities, precious for diverging inside the air inlet 2
Tower-like, and the dust-proof cotton for filtering is placed with along pagoda shape cavity wall.Air inlet internal structure assumes diverging pagoda shape so that gas
Stream back pressure reduces, while dust in air is diffused to dust-proof cotton surrounding, does not block medium position, increases dust-proof cotton and filter tip
Use time.
In the present invention, it is provided with the middle part of the filter tip body 1 for being fixed the through hole of installation.Two in the middle part of filter tip
Two through holes of the reserved φ 2.2mm in side, the Cross Recess Head Screw for two M2 × 6 are fixed on housing filter tip.
The present invention the course of work be：
When air sampling rig is sampled, sample gas enter air inlet 2 by pipeline, are then arranged by the back side
There is the interface 4 being connected with air sampling rig entrance, in air inlet sampling apparatus, carry out Data Detection, when completing to detect
Afterwards, discharged from gas outlet 3 by outgassing column 5.
The purpose of the present invention is the defect for overcoming prior art, there is provided a kind of rational in infrastructure, and sampling is accurate, monitoring efficiency is high
Filter tip.For solving above-mentioned technical problem, the present invention adopts main points contour structures.Design feature, air inlet
Upward, gas outlet greatly prevents falling into for gas outlet debris towards side.In addition sampling head can embedded product install, it is to avoid because
The accidental damage for projecting housing and bringing.
The invention has the beneficial effects as follows, meet curstomer's site use demand, assembling assembling demand, outward appearance practical application need
Ask, gather accuracy requirements, using the present invention：
1st, lateral outlet, does not block outlet side, more effectively meets curstomer's site use.
2nd, crossed pan head screw fastening, convenient dismounting and assembling.
3rd, outward appearance is symmetrical, possesses dedusting breach, prevents dust accretions, the sight line of the internal dust-proof cotton of obstruction observation.
4th, internal structure more effectively consolidates the accuracy of collection gas.
