Description
Technical field
The utility model belongs to environment monitoring instrument field more particularly to a kind of filter membrane group for air particle sampling
Part.
Background technique
Air granule sampler traps the suspended particulate substance in ambient air by filter membrane weight method, for in air
The monitoring of pellet.Air granule sampler used at present generally uses filter membrane clip support and fixed filter membrane, filter
Film support net and filter membrane pressure ring are not readily separated, and filter membrane is not easily taken out, and filter membrane is easily broken.
Further according to standard, filter membrane needs to be numbered by hand by the staff in laboratory and weighed repeatedly, adopts if necessary
Collect and weigh a large amount of sample, it is very difficult to distinguish different filter membranes, and number takes time and effort by hand.
Utility model content
The utility model picks and places slow, easily damaged technical problem for existing filter membrane out of filter membrane clip, proposes one
Kind filter membrane component small in size and light-weight, the filter membrane component can protect filter membrane and can integrally weigh, and fetch conveniently；Filter membrane group
Identification code is arranged on part can distinguish different filter membranes.
In order to achieve the above object, the technical solution adopted in the utility model are as follows:
A kind of filter membrane component for air particle sampling, including pressing ring, filter membrane and filter membrane support, the filter membrane support include
Bottom surface and circular ring shape side wall, filter membrane with porous structure are placed on bottom surface, and pressing ring is mounted in filter membrane support, on the pressing ring
It is provided with identification code.
Preferably, the filter membrane support Sidewall Height is 2.0-4.0mm.
Preferably, filter membrane backing face includes the weft of concentric circles arrangement and the warp of radial arrangement.
Preferably, the identification code is the bar code of imprinting or printing.
Preferably, the identification code is the two dimensional code of imprinting or printing.
Preferably, the pressing ring and filter membrane support material are PC/ABS plastics.
Compared with prior art, the advantages of the utility model and have the active effect that the filter membrane component using filter membrane support and
Pressing ring protects filter membrane piece, and overall volume is small, light-weight, and when use is placed in filter membrane clip as common filter membrane to be sampled.
Weighing can be directly taken out after sampling.It fetches that filter membrane is very convenient, can effectively ensure that the integrality of filter membrane, it is ensured that sample
It is complete effective.Identification code is set on pressing ring, and identification code guarantees the uniqueness of filter membrane, can distinguish filter membrane, convenient for record data.

Specific embodiment
In order to better understand the utility model, illustrate with reference to the accompanying drawings and examples.
Embodiment: as shown in Figure 1 and Figure 2, a kind of filter membrane component for air particle sampling, including pressing ring 1, filter membrane 2
And filter membrane support 3.The filter membrane support 3 includes bottom surface 31 and the circular ring shape side wall 32 with porous structure, 3 side wall of filter membrane support, 32 thickness
For 3.0mm, filter membrane 2 is placed on bottom surface 31.Pressing ring generally circular ring shape is diametrically greater than lower part thereon, and 1 lower part of pressing ring passes through
Interference fit is fastened in filter membrane support 3, is guaranteed that filter membrane 2 is compacted, be will not fall off.To allow the flow to pass through filter membrane 2, institute
It states 3 bottom surface 31 of filter membrane support and is set as the weft 34 of concentric circles arrangement and the warp 33 of radial arrangement, 34 structure of warp 33 and weft
At the porous structure of large aperture, 3 material selection PC+ABS plastics of pressing ring 1 and filter membrane support, light-weight and not cracky.
To distinguish different filter membranes 2, it is provided with identification code 4 on the pressing ring 1, which can pass through imprinting machine engraving
Record or printing, identification code 4 can be bar code, or two dimensional code etc. other be able to record the identification code 4 of information.
Filter membrane component described in the present embodiment protects filter membrane piece using filter membrane support 3 and pressing ring 1, and overall volume is small, weight
Gently, it is placed in filter membrane clip and samples as common filter membrane when use.Weighing can be directly taken out after sampling.Fetch filter membrane
It is very convenient, it can effectively ensure that the integrality of filter membrane, it is ensured that sample is completely effective.Identification code 4, identification are set on pressing ring 1
Code 4 guarantees the uniqueness of filter membrane, can distinguish filter membrane, convenient for record data.
The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of variation is applied to other fields, but all without departing from the content of the technical scheme of the utility model, according to this reality
With novel technical spirit any simple modification, equivalent variations and remodeling to the above embodiments, it is practical new to still fall within this
The protection scope of type technical solution.
