Background technology
At present, the opium pipe that is used for smoke dust sampling has compositions such as thief hatch, sampling pipe, filter cylinder sleeve pipe, and the draft that relies on sampling pump to provide sucks the particle in the flue in the smoke dust sampling gun, and aerosol sample become trapped in the filter cylinder, when sampling finishes, cut off the power of sampling pump.Traditional opium pipe is because the cartridge assembly project organization is simple, though it is big to collect quality, the soot dust granule thing that concentration is high because the quality of filter cylinder own is also many to the flue dust weightening finish that is collected, has reduced the accuracy of weighing.
Summary of the invention
In order to overcome the deficiency of above opium pipe when gathering flue dust, develop a kind of opium pipe that is applicable to the low concentration smoke dust sampling.
The opium pipe that is applicable to the low concentration smoke dust sampling in the utility model includes pitot tube, sampling pipe, cartridge assembly, locking cap, connecting pipe, opium pipe handle and double end valve, one end of described pitot tube is connected with double end valve in the described opium pipe handle through described connecting pipe, an end of described sampling pipe is through described cartridge assembly simultaneously, connect with described behind the locking cap, described connecting pipe is connected with double end valve in the described opium pipe handle again, described cartridge assembly includes the sampling headstock that is tightly connected with described sampling pipe, the filter cylinder seat of honour that is tightly connected with described sampling headstock, be used to seal the filter cylinder base at the described filter cylinder seat of honour and be used for the sealing locking described filter cylinder seat of honour and filter cylinder base filter cylinder locking cap, between the described filter cylinder seat of honour and described filter cylinder base, be provided with the filter cylinder cover that is used to be provided with aperture filter screen and filter membrane.
The front end of described sampling pipe is the half U type structure of radius bend one-tenth and horizontal parallel.
The end that described sampling pipe is not connected with described cartridge assembly is provided with sampling head, and on described sampling head rain cover is set.
Be provided with the filter cylinder base sealing gasket that increases sealing effectiveness between described filter cylinder cover and the described filter cylinder seat of honour and the filter cylinder base, and between the described filter cylinder seat of honour and described filter cylinder cover inwall, be provided with trim ring.
Between described filter cylinder cover and the trim ring described filter screen is set, and places described filter membrane on described filter screen, described filter screen lower floor is the radioactivity shape of punctuating, and it is circular that the upper strata is radioactivity.
Be formed with the sealing room that is used to collect flue dust of cone shape in the described sampling headstock and the described filter cylinder seat of honour.
The opium pipe that is applicable to the low concentration smoke dust sampling in the utility model is by using a filter screen that is covered with the small-bore on cartridge assembly, on filter screen, place filter membrane again, and the cone sealing room that makes filter screen and filter membrane place cartridge assembly to form, replaced traditional simple filter cylinder, when flue dust enters into the filter screen of opium pipe front end by the sampling pipe bend, finer particle is deposited on the filter membrane, the flue dust in the time of can collecting low concentration; The filter screen of this moment is also littler with the relative conventional filtration cartridges of particle quality proportion, it is littler to increase weight, thereby solved the problem that traditional opium pipe cartridge assembly can only be finished the high smoke dust sampling of concentration, more be applicable to the smoke dust sampling of low concentration, also improved the accuracy of sampling.
Opium pipe in the utility model can be widely used in the environomental pollution source smoke dust sampling of departments such as environmental protection, industrial and mining enterprises, cooperates smoke dust sampling instrument to use jointly, can monitor the dust concentration of pollution source in the air.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment among the present invention is described in further detail.
As depicted in figs. 1 and 2, be applicable in the utility model that low concentration smoke dust sampling opium pipe comprises pitot tube 1, sampling pipe 2, cartridge assembly 3, locking cap 4, connecting pipe 5, opium pipe handle 6 and double end valve 7 wherein:
Pitot tube 1 is used to derive flue dust.
Sampling pipe 2 be connected with sampling head 20 foremost, this sampling head 20 can adopt different caliber size as required, to adapt to different occasions, can be provided with the rain cover (not shown) at these sampling head 20 places, prevents entering of rainwater.The front end of sampling pipe 2 is the enough big radius bend one-tenth and the half U type structure of horizontal parallel, and curve transition does not smoothly have obvious impression, the surface finish no marking.
Cartridge assembly 3 front ends connect sampling pipe 2, the rear end connects connecting pipe 5 behind locking cap 4, pitot tube 1 also is connected with connecting pipe 5 simultaneously, enter in the opium pipe handle 6, and be connected with other equipment (as aspiration pump etc.) through double end valve 7, can derive the flue dust of collecting by pitot tube 1 and sampling pipe 2, be prior art, no longer describe in detail owing to reach the measurement component and other parts (sampling thief) that are connected with the opium pipe handle in the opium pipe handle 7.Cartridge assembly 3 includes sampling headstock 30, the filter cylinder seat of honour 31, filter cylinder locking cap 32, filter cylinder base sealing gasket 33, trim ring 34, filter cylinder cover 35 and filter cylinder base 36, as shown in Figure 3 and Figure 4.
Sampling pipe 2 is connected through thread seal with sampling headstock 30, and the headstock 30 of sampling simultaneously also is connected by thread seal with the filter cylinder seat of honour 31, and in the sample headstock 30 and the filter cylinder seat of honour 31 room 38 of the end sealing of an inversed-cone shape of formation, be used to collect flue dust.Filter cylinder base 36 is located at the end that the filter cylinder seat of honour 31 is not connected with sampling headstock 30, and between the filter cylinder seat of honour 31 and filter cylinder base 36, be provided with filter cylinder base sealing gasket 33, trim ring 34 and filter cylinder cover 35, relend by filter cylinder locking cap 32 and be connected and fixed, can make filter cylinder base 36 and the filter cylinder seat of honour 31 fast quick-detach by filter cylinder locking cap 32 simultaneously.Between filter cylinder locking cap 32 and the filter cylinder base 36 by being threaded, filter cylinder cover 35 wherein is set between the filter cylinder seat of honour 31 and filter cylinder base 36, simultaneously between filter cylinder cover 35 and the filter cylinder seat of honour 31 and filter cylinder base 36, be provided for increasing the filter cylinder base sealing gasket 33 of sealing effectiveness, and overlap at the filter cylinder seat of honour 31 and filter cylinder trim ring 34 is set between 35 inwalls.Centre at filter cylinder cover 35 is provided with aperture filter screen 37, and places filter membrane 39 on filter screen 37, and wherein filter screen 37 lower floors are the radioactivity shape of punctuating, and it is circular that the upper strata is radioactivity.The utility model is owing to utilize filter membrane to substitute the method for sampling of conventional filtration cartridges, greatly reduce the flue dust that collects claim error, be applicable to the smoke dust sampling of low concentration.Being threaded of adopting in the utility model can certainly be that other are sealedly connected and fixed, and this is to realize easily to one skilled in the art, enumerates no longer one by one.
In sum, the utility model substitutes the method for sampling of conventional filtration cartridges with frivolous filter membrane 39, has adopted the filter screen of special construction simultaneously, greatly reduces the error that the flue dust that collects is weighed, and is applicable to the low concentration smoke dust sampling.
