Abstract
The utility model discloses a dustproof filter tip, including the filter tip body, the front of filter tip body is provided with the air inlet, with front vertically side goes upward and is provided with the gas outlet, and the back of filter tip body is provided with the interface that is connected with air sampling device entry and exports the play gas column that is connected with the air sampling device, and wherein, the interface is linked together with the air inlet, goes out the gas column and is linked together with the gas outlet. The gaseous air inlet of gathering will carry out and gather after carry out carminative gas outlet and set up perpendicularly for the gas that gets into does not block the end of giving vent to anger, more effectively satisfies customer's field usage, has improved the accuracy and the practicality of detection.
Description
Technical field
The utility model belongs to air sampling rig field, is specifically related to a kind of dustproof filter mouth.
Background technology
Along with science and technology and industrial develop the continuous improvement with living standards of the people rapidly, the air quality problems closely bound up with people's daily life is also more and more subject to people's attention, suspend aerial solid or liquid particles thing, can work the mischief to people and other biological health, air pollution and great focus in the world has been become to its environmental monitoring, therefore, market there is a feast for the eyes air sampler transition joint, the dustproof filter mode of sampler is varied simultaneously, and collecting efficiency is different.
Various filter tip service efficiency is different, therefore cannot reach more higher leveled accuracy in control accuracy, and also therefore, there is larger measure error to sampled result, this just makes environmental monitoring results inaccurate.
Utility model content
For above-mentioned defect or deficiency, the purpose of this utility model is to provide a kind of rational in infrastructure, the dustproof filter mouth that sampling accurately, monitoring efficiency is high.
For reaching above object, the technical solution of the utility model is:
Comprise filter tip body, the front of filter tip body is provided with air inlet, gas outlet is provided with the side of described front vertical is up, the back side of filter tip body is provided with the interface that is connected with air sampling rig entrance and exports with air sampling rig the outgassing column be connected, wherein, interface is connected with air inlet, and outgassing column is connected with gas outlet.
Described interface is provided with seal groove, and seal groove and air sampling rig entrance are sealed by sealing ring and engage.
The front of described filter tip body offers the groove for carrying out surface dust.
The root of described outgassing column is provided with the O type circle for sealing.
Described air inlet inside is placed with the dust-proof cotton for filtering.
The through hole for being fixed installation is provided with in the middle part of described filter tip body.
Compared with the prior art, the beneficial effects of the utility model are:
The utility model provides a kind of dustproof filter mouth, by carry out gas collecting air inlet and after gathering the gas outlet that is exhausted vertically arrange, make the gas entered not block outlet side, more effective meet curstomer's site use, improve accuracy and the practicality of detection.In addition, the utility model arranges at the back side of filter tip body and exports with air sampling rig the outgassing column be connected, make outgassing column and air sampling rig export compact siro spinning technology, quick position is installed, improve the convenience that product is installed, improve the sealing of collecting device, improve acquisition precision and the collecting efficiency of device.
Further, the utility model offers through hole at filter tip body, by crossed pan head screw fastening, for convenience detach with assembling.
Accompanying drawing explanation
Fig. 1 is filter structure schematic diagram 1 of the present utility model;
Fig. 2 is filter structure schematic diagram 2 of the present utility model;
Fig. 3 is filter tip of the present utility model knot side view.
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, and 7 is groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As Figure 1-3, the utility model provides a kind of dustproof filter mouth, comprise filter tip body 1, the front of filter tip body 1 is provided with air inlet 2, just uply towards vertical side be provided with gas outlet 3 with described, the back side of filter tip body 1 is provided with the interface 4 that is connected with air sampling rig entrance and exports with air sampling rig the outgassing column 5 be connected, wherein, interface 4 is connected with air inlet 2, and outgassing column 5 is connected with gas outlet 3.Air inlet is vertical with final direction, gas outlet, avoids the problems such as obstruction, inconvenience of giving vent to anger.The front of described filter tip body 1 offers the groove 7 for carrying out surface dust.Filter tip in the utility model is injection molded, surperficial cloudy surface process, and object is to see above dust-proof cotton dust how many whiles, not see the structure of housing filter tip draw-in groove.
Filter tip lower end devises axial seal mode, and described interface 4 is provided with seal groove 6, and after seal groove 6 and air sampling rig entrance add sealing ring, sealing engaging, makes air inlet reach sealing effectiveness; The root of described outgassing column 5 is provided with the O type circle for sealing.
Further, in order to improve accuracy of detection, avoid collecting other impurity, described air inlet 2 inside for dispersing pagoda shape, and is placed with the dust-proof cotton for filtering along pagoda shape cavity wall.Air inlet internal structure presents disperses pagoda shape, and air-flow back pressure is reduced, and dust in air is diffused to dust-proof cotton surrounding simultaneously, does not block medium position, increase dust-proof cotton and filter-tip service time.
In the utility model, in the middle part of described filter tip body 1, be provided with the through hole for being fixed installation.In the middle part of filter tip, two through holes of Ф 2.2mm are reserved on both sides, and the Cross Recess Head Screw for two M2 × 6 is fixed on housing filter tip.
The course of work of the present utility model is:
When air sampling rig is sampled, sample gas enters air inlet 2 by pipeline, is then provided with the interface 4 be connected with air sampling rig entrance by the back side, enters in air sampling rig and carry out Data Detection, after completing detection, discharged from gas outlet 3 by outgassing column 5.
The purpose of this utility model is the defect overcoming prior art, provides a kind of rational in infrastructure, the filter tip that sampling accurately, monitoring efficiency is high.For solving the technical problem of above-mentioned existence, the utility model adopts main points contour structures.Design feature, upward, gas outlet, towards side, greatly prevents falling into of gas outlet foreign material to air inlet.In addition sampling head can be installed by embedded product, avoids the accidental damage brought because of outstanding housing.
The beneficial effects of the utility model are, meet curstomer's site user demand, assembling assembling demand, outward appearance practical application request, gather accuracy requirements, use the utility model:
1, side direction is given vent to anger, and does not block outlet side, more effective meet curstomer's site use.
2, crossed pan head screw fastening, for convenience detach with assembling.
3, outward appearance is symmetrical, possesses dedusting breach, prevents dust accretions, blocks the sight line of observing inner dust-proof cotton.
4, the accuracy of the more effective firm collection gas of internal structure.
