Abstract
For a protection ring for stationary pollution source particle sampling filter cylinder, described protection ring body is hollow structure, and one end is folded-out, forms bending part.The beneficial effects of the utility model are; protection ring of the present utility model can protect filter cylinder well; ensure the integrality of filter cylinder; thus the precision of monitoring is more accurate; on protection ring, be equipped with bending part simultaneously; be more convenient for picking and placeing of filter cylinder; bar code or digitally coded setting; improve the speed of reading; avoid again the confusion causing reading simultaneously; the setting of catch net or rib and base ring more protects filter cylinder and protection ring, is particularly useful for low concentration or high humility sampling thief.
Description
Technical field
The utility model relates to a kind of protection ring, particularly a kind of protection ring for stationary pollution source particle sampling filter cylinder, is particularly useful for low concentration or the high humility sampling thief of stationary pollution source particle sampling, belongs to field of environment protection.
Background technology
Filter cylinder is the vitals of sampling, is mainly carried out the concentration of monitoring pollution thing or particle during the sampled measurements pollutant of filter cylinder by gravimetric method.Gravimetric method is exactly that the weight of filter cylinder before and after sampling is compared analysis, and draw PM2.5 particle concentration value in this regional air, committed step is wherein weighing to filter cylinder.But in the placement of filter cylinder or the process of transport, if can not effectively protect filter cylinder, then may cause the deviation of measurement result, even cause the failure realizing result, wasting manpower and material resources.Therefore, in the sampling process of filter cylinder, need to ensure that filter cylinder preserves from, the accuracy of filter cylinder weight can be ensured well.And filter cylinder is more easily taken out.
Utility model content
For the deficiencies in the prior art, problem to be solved in the utility model is, a kind of protection ring of stationary pollution source particle sampling filter cylinder is provided, its structure is simple, and filter cylinder can be protected not to be destroyed, and more easily takes out simultaneously, simultaneously owing to being provided with bar code or numerical coding, more conveniently read, the setting of catch net or rib, base ring, can prevent filter paper from coming off; Protection ring of the present utility model is particularly useful for low concentration or high humility sampling thief.
For solving the problems of the technologies described above, the technical solution of the utility model is, a kind of protection ring of stationary pollution source particle sampling filter cylinder, and described protection ring body is hollow structure, and one end is folded-out, forms bending part.
Further, the described protection ring body other end is connected with rib, and rib opposite side is connected with a base ring.
Further, described protection ring bottom is equipped with catch net.
Further, described protection ring is equipped with numerical coding or bar code.
The beneficial effects of the utility model are, protection ring of the present utility model can protect filter cylinder well, ensure the integrality of filter cylinder, thus the precision of monitoring is more accurate, on protection ring, be equipped with bending part simultaneously, be more convenient for picking and placeing of filter cylinder, bar code or digitally coded setting, improve the speed of reading, avoid again the confusion causing reading simultaneously, the setting of catch net or rib and base ring more protects filter cylinder and protection ring, be particularly useful for low concentration or the high humility sampling thief of stationary pollution source particle sampling, belong to field of environment protection.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in more detail
Fig. 1 is the structural representation of the utility model protection ring;
Fig. 2 is the structural representation of the utility model protection ring with rib;
Fig. 3 is the structural representation of the utility model protection ring with catch net.
Embodiment
embodiment 1
As described in Fig. 1,2, a kind of protection ring for stationary pollution source particle sampling filter cylinder, described protection ring 1 body is hollow structure, and one end is folded-out, forms bending part 2.Protection ring 2 of the present utility model can be arranged at the different position of relative filter cylinder as required; according to specific needs; select different size; the protection ring 2 of different size, the setting of protection ring 2 one end bending part, facilitates picking and placeing of filter cylinder to a great extent; the shape of the utility model bending part can according to different filter cylinders; different samplings, the shape of suitable change bending part, size and position, be not merely confined to the shape of protection ring bending part of the present utility model.In order to convenient reading sampling, further, described protection ring 2 is equipped with numerical coding 3 or bar code 4.Numerical coding 3 of the present utility model and bar code 4 can be used alone, and also can use simultaneously, when using at the same time, by dual reading, avoid mistake during reading.The utility model is connected with rib 5 at the protection ring 2 body other end, and rib 5 opposite side is connected with a base ring 6; The rib 5 that the utility model is arranged and base ring 6, when can prevent from well sampling, filter paper comes off, and decreases wrong odds.
embodiment 2
As shown in Figure 1,3; for a protection ring for stationary pollution source particle sampling filter cylinder, be provided with described protection ring 2 bottom and be equipped with catch net 7, catch net 7 to act on rib 5 consistent with the effect that base ring 6 matches; during for preventing from sampling, filter paper comes off, and decreases wrong odds.
As mentioned above, we are illustrated according to aim of the present utility model completely, but the utility model is not limited to above-described embodiment and implementation method.Different changes and enforcement is carried out in the scope that the practitioner of correlative technology field can permit at technological thought of the present utility model.
