Abstract
A filter membrane detecting atmospheric particles used for an automatic weighing system comprises a filter membrane body, a bar code and a serial number, wherein the bar code and the serial number are stuck on the filter membrane body, and are symmetric about the transverse shaft of the filter membrane body. The filter membrane has the benefits that the filter membrane is simple in structure, scientific in design, convenient to work, and flexible to use; quick record can be conducted on the filter membrane.
Description
Technical field
The present invention relates to a kind of filter membrane, relate in particular to a kind of filter membrane detecting for automatic weighing system Atmospheric particulates, belong to environmental monitoring field.
Background technology
Aerated particle thing refers to the solid-state or liquid particles shape material being dispersed in atmosphere, according to its particle size, can be divided into again the pellet (PM10) that overall suspended pellet (TSP) that aerodynamic diameter is less than or equal to 100 um and aerodynamic diameter are less than or equal to 10um.Pellet can be subdivided into again particulate PM2.5 (aerodynamic diameter is less than or equal to 2.5 u m) and coarse grain (aerodynamic diameter is between 2.5 um to 10 um).Particulates thing of the prior art pollutes is not only the main cause that causes haze weather, and particularly pellet (PM2.5: be less than or equal to 2.5 micron particles things) can impact the health of human body, mainly respiratory system and cardiovascular system is damaged.Therefore particulate in air concentration is one of major criterion of judgement air quality.
Gravimetric method is exactly that the weight before and after sampling compares analysis by filter membrane, draws PM2.5 particle concentration value in this regional air, and committed step is wherein weighing to filter membrane.Yet in the placement of filter membrane or the process of transportation, if can not filter membrane be effectively protected, may cause the deviation of measurement result, even cause realizing the failure of result, wasting manpower and material resources.Yet all write mark and recorded filter membrane by craft for the record of filter membrane now, numbered, artificial working strength is large, and efficiency is low, has wasted a large amount of manpower and materials.
Utility model content
For the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, and design science is worked convenient, uses filter membrane flexibly, and it can carry out fast recording to filter membrane.
For solving the deficiencies in the prior art, the technical scheme that the utility model provides is that a kind of filter membrane detecting for automatic weighing system Atmospheric particulates, comprises filter membrane body, bar code and sequence number, described bar code and sequence number are attached on filter membrane body, and its transverse axis about filter membrane body is symmetrical.
Optimisation technique scheme of the present invention is that described bar code and sequence number are attached to apart from 3 millimeters of places of filter membrane body edges.
Optimisation technique scheme of the present invention is that the range of size of described bar code and sequence number is wide 1-2.7 millimeter, long 3-7.2 millimeter.
The beneficial effects of the utility model are, because volume is little, do not take the useful area of filter membrane, can not affect the detection of Atmospheric particulates, and simultaneously special barcode encoding is clear, is convenient to automatic weighing system and reads fast.Convenient for ease of manual record, filter membrane is used in order, on the relative position of bar code, posts special sequence number, sequence number is consistent with barcode encoding, and this filter membrane is simple in structure, design science, work convenient, use flexibly, can significantly increase work efficiency.
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 embodiment.
Embodiment
As shown in Figure 1, a kind of filter membrane detecting for automatic weighing system Atmospheric particulates, comprises filter membrane body 2, bar code 1 and sequence number 3, and described bar code 1 is attached on filter membrane body 2 with sequence number 3, and its transverse axis about filter membrane body 2 is symmetrical.Described bar code 1 is attached to apart from place, 3 millimeters, 2 edge of filter membrane body with sequence number 3.The range of size of described bar code 1 and sequence number 3 is wide 1-2.7 millimeters, long 3-7.2 millimeter.
Bar code of the present utility model and sequence number are long-pending little, do not take the useful area of filter membrane, can not affect the detection of Atmospheric particulates, and simultaneously special barcode encoding is clear, is convenient to automatic weighing system and reads fast.Convenient for ease of manual record, filter membrane is used in order, on the relative position of bar code, posts special sequence number, and sequence number is consistent with barcode encoding.Computing machine can start the bar code scanning program of pasting on filter membrane automatically, scans, and automatically identifies the numbering of filter membrane, and stores; And progress and the performance of each mechanical action that can display system, such as the weighing progress of a filter membrane, whether there is warning message; Can show and weigh how many filter membranes (demonstration of weighing is green, the demonstration black not weighing, demonstration redness weighing etc.);
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.The practitioner of correlative technology field can carry out different variations and enforcement in the scope of technological thought license of the present utility model.
