Abstract
A kind of sampling head for the sampling of stationary source low concentrations of particulates thing, including filter cylinder support, embeds in filter cylinder support and is cased with filter cylinder, and the filter cylinder support is tightly connected with sampling mouth by aluminium foil circle.Filter cylinder support is tightly connected by sampling head of the present utility model with sampling mouth so as to be integrally formed, and integrally weighs sampling head when weighing, it is to avoid sampling impact of the mouth sweep to measurement result, measurement result are more accurate.
Description
Technical field
The utility model is related to a kind of sampling head for the sampling of stationary source low concentrations of particulates thing, it is adaptable to which filter cylinder is adopted
Sample, belongs to field of environment protection.
Background technology
In traditional sampling field, for the filter cylinder sampling of the particulate matter of the low concentration of stationary source, typically take
It is all the form that separates with filter cylinder support of mouth of sampling, during weighing, the filter cylinder in filter cylinder support is weighed.But the mistake in sampling
Cheng Zhong, has the sweep that sample segment is deposited in sampling head, causes the error of weighing result, it could even be possible to there are data
Mistake, causes measurement result inaccurate.Accordingly, it would be desirable to be further improved to existing structure.
Utility model content
For the deficiencies in the prior art, the technical problems to be solved in the utility model is to provide a kind of for fixed-contamination
The sampling head of source low concentrations of particulates thing sampling, by filter cylinder support is tightly connected with sampling mouth, is integrally formed, reduces error,
Make its measurement result more accurate.
For solving above-mentioned technical problem, the technical solution of the utility model is, a kind of for stationary source low concentration
The sampling head of grain thing sampling, including filter cylinder support, embeds in filter cylinder support and is cased with filter cylinder, and the filter cylinder support is by aluminium foil circle and sampling mouth
It is tightly connected.
Optimize, the filter cylinder support is hollow structure, in filter cylinder support is provided with rib.
Optimize, on rib or sampling mouth, be provided with bar code or digital coding.
Optimize, the sampling mouth includes that arc sections, arc sections are connected with vertical tube part by transition arc, in vertical tube part
Rear end be provided with the compressed part being adapted to filter cylinder support.
The beneficial effects of the utility model are that filter cylinder support is tightly connected by sampling head of the present utility model with sampling mouth, is made
Which is integrally formed, and integrally weighs sampling head when weighing, it is to avoid sampling impact of the mouth sweep to measurement result, measurement knot
Fruit is more accurate.
Description of the drawings
Fig. 1 is the structural representation of the sampling head for the sampling of stationary source low concentrations of particulates thing of the present utility model.
Specific embodiment
The utility model is described in more detail with reference to the accompanying drawings and examples；
As shown in figure 1, a kind of sampling head for the sampling of stationary source low concentrations of particulates thing, including filter cylinder support 1, in filter
Cylinder support 1 is embedded to be cased with filter cylinder 2, and the filter cylinder support 1 is tightly connected with sampling mouth 4 by aluminium foil circle 3.The filter cylinder support 1 is hollow
Structure, is provided with rib 5 in filter cylinder support 1.Bar code 6 or digital coding 7 is provided with rib 5, naturally it is also possible to adopted
Bar code 6 or digital coding 7 is provided with sample mouth 4.The sampling mouth 4 includes arc sections 8, arc sections 8 by transition arc with
Vertical tube part 9 is connected, and is provided with the compressed part 10 being adapted to filter cylinder support 1 in the rear end of vertical tube part 9.
During use, filter cylinder 2 is positioned in filter cylinder support 1, while the compressed part 10 of sampling mouth 4 is positioned over filter cylinder support 1
Compress at opening, and sampling mouth 4 is tightly connected with filter cylinder support 1 using aluminium foil circle 3, it is to avoid ectocine, improve certainty of measurement.
Filter cylinder support is tightly connected by sampling head of the present utility model with sampling mouth so as to be integrally formed, the entirety when weighing
Weigh sampling head, it is to avoid sampling impact of the mouth sweep to measurement result, measurement result are more accurate.Through researcher
Dependence test is carried out, sampling head of the sampling head of the present utility model with traditional separate type is carried out contrast test, certainty of measurement
5%-8% is improve, and then preferably ensure that the accuracy of sampling.
As described above, we are illustrated fully according to objective of the present utility model, but the utility model not limits to
In above-described embodiment and implementation.The practitioner of correlative technology field can be in the scope of technological thought of the present utility model license
Different changes and enforcement are inside carried out.
