Description
Technical field
The utility model is related to air detection equipment technical field, and in particular to a kind of sampler of quick sampling air.
Background technology
Air sampler is a kind of supplementary instrument, and the tested gas pollutant that be detected in surrounding air can be adopted
Collection is extracted, and the gas pollutant concentration that can just detect to be detected in surrounding air is used in conjunction with the instrument such as gas chromatograph.
A kind of existing air sampler includes adsorbent post core, filter layer, base and outer cover, and wherein adsorbent post core is set
It is placed in center position and is connected with base, filter layer is arranged at the outside of adsorbent post core, outer cover is arranged at filter layer
Outside, and filter layer and outer cover be connected with base.
But, because filter layer is porous material layer, after sampling terminates, the gas molecule for being adsorbed in filter layer can be to absorption
Agent post core is polluted, and causes testing result inaccurate.Therefore dividing plate is provided with outer cover outer cover is divided into the first cavity volume
With the second cavity volume, when base is combined with outer cover, adsorbent post core is located in the first cavity volume, and filter layer is located in the second cavity volume, from
And prevent that filter layer from polluting adsorbent post core.
When being sampled, outer cover is extractd, pedestal stood in atmosphere, the gas in test environment can be via filtering
Layer is in contact with adsorbent post core, it is to be sampled at the end of, then outer cover is installed on base.Because adsorbent post core is quiet in the device
Put, air flow is smaller, it is necessary to longer sample time.
Utility model content
The purpose of this utility model is to provide a kind of sampler that quickly can be sampled to air, while the sampling
Device can also prevent that filter layer from polluting adsorbent post core.
To reach above-mentioned purpose, base case of the present utility model is as follows：
The sampler of quick sampling air includes adsorbent post core, filter layer, base and seal closure, be provided with seal closure every
Seal closure inner chamber is divided into the first cavity volume and the second cavity volume by plate, and adsorbent post core and filter layer are fixedly connected with base, and is inhaled
Attached dose of post core is arranged at the inner side of filter layer, the top closure of seal closure, the bottom end opening of seal closure, the bottom and bottom of seal closure
Seat, which coordinates, can seal the first cavity volume and the second cavity volume；Second cavity volume is surrounded on the outside of the first cavity volume, and adsorbent post core is placed in
First cavity volume, filtering is placed on the second cavity volume.
The base lower end is provided with sliding handle, the lower end of the seal closure be provided with the integrally formed sliding sleeve of seal closure, it is described
The upper end of sliding sleeve is provided with multiple air admission holes, and the sliding sleeve is slidably connected on sliding handle, and the length of the sliding handle is more than adsorbent post
The length of core.
The principle of the sampler of this programme quick sampling air is：
When being sampled to air, sliding sleeve is set to be slided up and down along sliding handle, and during upward sliding sliding sleeve, then seal closure, sliding sleeve
The space constituted with base will gradually increase, and air admission hole departs from sliding handle and corresponds to adsorbent post core, therefore air will pass through
Air admission hole enters in seal closure.When air-flow flows into seal closure, filter layer will filter out the bulky grain in air, and adsorbent
The pernicious gas that post core will be adsorbed in air, so as to be acquired to the pernicious gas in air.It is close when sliding sleeve slide downward
The space that sealing cover, sliding sleeve and base are constituted will be gradually reduced, and air is discharged by air admission hole, then can will be adsorbed in filtering
Bulky grain on layer blows off, so as to prevent that dust stratification is excessive on filter layer, influences filter effect.
When sliding sliding sleeve, air always enters seal closure from air admission hole, when the timing charge flow rate of sliding speed one is certain；
And in sliding process, air admission hole will gradually be moved to adsorbent post core upper end from the lower end of adsorbent post core, so as to make sky
Pernicious gas in gas is uniformly adsorbed on adsorbent post core.
Filter layer is made of porous materials, after gas sampling is finished, and substantial amounts of gas molecule can be also adsorbed on filter layer,
Therefore in order to prevent that sampling from terminating after, the gas molecule adsorbed on filter layer is diffused on adsorbent post core so that adsorbent post
Core and air are actual to touch overlong time, influences sampled result；Therefore when seal closure closes adsorbent post core, adsorbent post
Core is in the first cavity volume, and filter layer is in the second cavity volume.
This programme produce beneficial effect be：
（One）The flowing of gas can be strengthened by sliding sliding sleeve, so as to accelerate the speed that adsorbent post wicks attached pernicious gas
Degree, shortens the sampling time.
（Two）The sampler of the quick sampling air is by air inlet gas inlet hole, in intake process, and the size of air admission hole is not
Become, and air admission hole flow always, while air admission hole is moved to the upper end of adsorbent post core from adsorbent post core lower end, therefore can
Pernicious gas is set uniformly to adsorb on adsorbent post core.
（Three）When air admission hole is vented, filter layer upper end bulky grain can be blown off, so that filter layer is in air sampling process
It is middle to keep preferable filter effect.
Preferred scheme one：As the further optimization to base case, the base upper end is provided with porous protective cover, described
Filter layer is attached to porous protective cover inwall；Due to being made of materials such as filter papers more than filter layer, porous protective cover is to filtering
Layer has protective effect, can prevent that filter layer from deforming under the pressure that air-flow is produced.
Preferred scheme two：As the further optimization to preferred scheme one, the porous protective cover detachably connects with base
Connect, the upper end of the porous protective cover is provided with the sealing ring coordinated with seal closure inwall.Porous protective cover detachably connects with base
It is connected to beneficial to replacing adsorbent post core, and can prevents that bulky grain from passing through from gap in the upper end setting sealing ring of porous protective cover
Second cavity volume enters the first cavity volume and pollutes adsorbent post core.
Preferred scheme three：As the further optimization to preferred scheme two, the dividing plate bottom is set to arc, the base
Be provided with the arc groove coordinated with dividing plate bottom, after coordinating dividing plate bottom and arc groove, the first cavity volume it is close
Envelope property is more preferable.
Preferred scheme four：As the further optimization to preferred scheme three, it is fixed with the arc groove protruding upward
And the air cushion being made up of rubber, arc groove lower section is provided with air chamber, and air cushion inner chamber is connected with air chamber.When air cushion is oppressed in dividing plate lower end
When, air cushion will be deformed, and the gas in air cushion enters in air inlet chamber, so that air pressure increases, can strengthen the sealing of the first cavity volume；And work as
Dividing plate bottom departs from after cooperation with arc groove, because gas room pressure is larger, therefore air cushion will be raised again up, so as to
Prevent dust stratification in arc groove.
Preferred scheme five：As the further optimization to preferred scheme four, the sliding handle bottom is provided with jump ring, the sliding sleeve
Bottom is provided with neck corresponding with jump ring；When drop-down sliding sleeve makes jump ring coordinate with neck, then sliding sleeve can be positioned, it is to avoid sliding sleeve is certainly
It is dynamic to skid off so that seal closure seals adsorbent post core, and this is simple in construction, easy to operate.
