The air for pulling out air duct bottom is heated into hot-air by heater, heater, and hot-air, which rises, then to be pulled out outside air duct
The air in portion will pull out air holes by fresh air inlet entrance and be supplemented, and air-flow is formed in air duct so as to pull out, and the particle in medicament cage
The VOC of type adsorbent also constantly with the air contact that enters from fresh air inlet and in adsorbing air, so as to complete the sampling to air.
Sampling closes heater after finishing, and pulling up material storage tube makes material storage tube be slided in sealing drum, and it is close to slip into medicament cage
In sealed tube, it is air contact that can prevent granular pattern adsorbent, influences sampled result.
This programme produce beneficial effect be：
（One）The granular pattern adsorbent of multiple repairing weld can be stored in the gas pollutant sampling apparatus by material storage tube, is stored up
Barrel can seal granular pattern adsorbent, and sealed reliable, solve using hermetic bag to prevent granular pattern adsorbent and air
Contact the inconvenient and insecure problem brought；Filler particles type in medicament cage can be adsorbed additionally by extrusion piston
Agent, mode of operation is simple and filler is rapid.
（Two）After sampling is finished, upward sliding material storage tube can slip into medicament cage in sealing drum, so that in medicament cage
Granular pattern adsorbent be in sealing state, prevent granular pattern adsorbent again with air contact, influence sampled result.
Preferred scheme one：As the further optimization to base case, the material storage tube is provided with locating slot, the sealing
Cylinder inwall is provided with reed corresponding with locating slot；So as to which medicament cage is positioned in sealing drum, and the elastic force for passing through reed
It can prevent that medicament cage from skidding off out of sealing drum.
Preferred scheme two：It is used as the further optimization to preferred scheme one, the inwall and material storage tube of the sealing drum upper end
Outer wall spline fitted；To prevent that material storage tube from rotating relative to sealing drum, be conducive to reed corresponding with positioning groove location.
Preferred scheme three：As the further optimization to preferred scheme two, the upper and lower ends of the medicament cage are equipped with close
Seal；After medicament cage is slipped into sealing drum, the inwall of sealing ring and sealing drum coordinates, and is more beneficial for medicament cage and is in sealing shape
State.
Preferred scheme four：As the further optimization to preferred scheme three, the medicament cage is threadedly coupled with material storage tube；From
And can be connected to medicament cage is more stable on material storage tube, and be also convenient for dismantling medicament cage, the granular pattern in medicament cage is adsorbed
Agent is taken out.
