Embodiment
Solid-Phase Extraction sampling thief as shown in Figure 2, comprises body 1 and the bottle cap 2 being connected to body 1 top end opening place, is provided with adsorption piece 6 in body 1.Bottle cap 2 and body 1, can dismounting adsorption pieces 6 after being opened by bottle cap 2 for being threaded.Preferred adsorption piece 6 is sponge.
As shown in Figures 2 and 3, bottle cap 2 is provided with admission piece 3, body 1 is provided with gas outlet relative to the bottom of bottle cap 2, and after sample gas enters from admission piece 3, as the solid formations such as particle are adsorbed by adsorption piece 6, gas discharges this sampling thief from gas outlet afterwards.In embodiment, admission piece 3 is made up of draft tube 31 and proliferation part 32.Wherein proliferation part 32 is positioned at body 1, and draft tube 31 connects proliferation part 32 and passes from bottle cap 2, and this draft tube 31 is tightly connected with bottle cap 2.
The effect of proliferation part 32 is uniformly dispersed in body 1 before being adsorbed by adsorption piece 6 by the sample gas entering body 1, avoids air-flow directly to adsorption piece 6 centric(al) impact, causes that adsorption piece 6 blocks, sample concentration skewness.
As further preferred embodiment, proliferation part 32 is a disk, and its inside is provided with the air distribution cavity 33 being communicated with draft tube 31, and the perisporium of disk is provided with the distribution through hole 34 of some connection air distribution cavities 33.Gas enters different distribution through holes 34 respectively from air distribution cavity 33, thus spreads to the surrounding of disk, the sample gas after diffusion again adsorb by adsorption piece 6.
As further preferred embodiment, the axis of distribution through hole 34 and the axial vertical of body 1, directly do not impact the center of adsorption piece 6 like this from distribution through hole 34 effluent air, can reach the object of evenly diffusion for this reason.
In order to meet diffusion further evenly, each distribution through hole 34 is distributed in the outer wall of proliferation part 32.
As further preferred embodiment, draft tube 31 is connected on bottle cap 2 removably.
As further preferred embodiment, body 1 bottom is dismountable is connected to outlet cap 4, and outlet cap 4 is connected to outlet nozzle 5, gas outlet is positioned on outlet nozzle 5.
In another embodiment, as shown in Figure 4, proliferation part 32 periphery is also provided with even distribution device 7, and this even distribution device 7 carries out secondary distribution by from distribution through hole 34 effluent air, make gas evenly be distributed in body.
Concrete, as shown in Figure 5 and Figure 6, even distribution device 7 comprises the stirring wheel 71 of a hollow, and the bottom of admission piece 3 is provided with a rotating shaft 72 rotationally, the middle part of stirring wheel 71 is connected to rotating shaft 72 bottom and can rotates with rotating shaft 72, and stirring wheel 71 is positioned at proliferation part 32 periphery.The perisporium of stirring wheel 71 is provided with several air distribution ports 73, some gas distribution channels 74 are provided with in the hollow space of stirring wheel 71, distribution through hole 34 and air distribution port 73 are communicated with to get up by these gas distribution channels 74, and distribution through hole 34 effluent air enters after air distribution port 73 through gas distribution channels 74 and enters adsorption piece 6.More excellent, gas distribution channels 74 has angle with the axis of distribution through hole 34, gas flows out rear shock gas distribution channels 74 outer wall from distribution through hole 34, one impulse force is applied to outer wall, the component of impulse force makes stirring wheel 71 be rotated counterclockwise, give vent to anger in rotation limit, stirring wheel 71 limit, therefore gas evenly can be covered with in the circumference of stirring wheel 71, further increases the equally distributed degree of sample.
In addition, in the above embodiments, be also provided with support component 8 in body 1, support component 8 supports the bottom of adsorption piece 6, for spacing to it.
The above be the utility model preferred embodiment, it does not form the restriction to the utility model protection domain.
