Description
Technical field
The present invention relates to atmosphere particle monitoring field more particularly to a kind of filter paper for ray method particle monitoring instrument
Pretreating device.
Background technique
The common monitoring method of Atmospheric particulates has at present: gravimetric method, attenuation sensors, oscillation microbalance method.Its
In attenuation sensors principle be after β ray passes through substance to be determined, strength retrogression's degree only with the quality that is pierced substance
It is related, and it is unrelated with its physics, chemical property.β attenuation sensors advantage is to require sample size seldom, can be automatically derived per hour
One monitoring data, reflects the situation of change of particulate in air concentration in real time, and can carry out data transmission, and is conducive to remotely supervise
It surveys and automatically controls, and greatly reduce labor workload.Therefore, β ray method has become atmosphere particle concentration
Automatic monitor for continuously instrument one of main measurement method.In monitoring process, the counting and sampling of blank space filter paper before sampling
The counting at the filter paper same position with dust spot is to influence the important link of measurement accuracy afterwards.The content of moisture can shadow in filter paper
Ring the size counted.It would generally be by the temperature and humidity for sampling sample gas in gas circuit into controlling in a certain range after over-sampling pipe.And
Filter paper before sampling is in instrument internal, its own water content is influenced by ambient enviroment temperature and humidity, especially high temperature and humidity
This influence is particularly evident under weather conditions.Currently, lacking before being counted to blank filter paper in ray method particle monitoring instrument
To the device of filter paper processing, it not can guarantee the water content of sampling front and back filter paper itself, will lead to the inaccuracy of monitoring data.
Summary of the invention
Present invention aim to address existing ray method particle monitoring instruments in the prior art in high temperature, high humidity weather ring
The inaccurate problem of measured value under border, provides that a kind of structure is simple, reliable for operation, can be to the dress that filter paper is handled before counting
It sets.
The technical solution adopted by the present invention is that: a kind of filter paper pretreating device for ray method particle monitoring instrument, packet
U-shaped seat is included, support is connected on the U-shaped seat, passes through fixed cover on the support and is connected with heating sheet；The support two sides point
Not She You bearing mounting blocks, roller bearing is equipped on the bearing mounting blocks, the roller bearing passes through the affixed U-shaped seat of rolling bearing；Institute
The top for stating heating sheet is equipped with Temperature and Humidity module.
As a further improvement of the present invention, the spacing between the heating sheet and Temperature and Humidity module is 3~5mm,
The sensor probe of Temperature and Humidity module is apart from filter paper 2mm or so.
As a further improvement of the present invention, the heating sheet is ceramic heating flake.
As a further improvement of the present invention, the U-shaped seat side is equipped with body frame, and the other side is equipped with baffle.
The beneficial effect that the present invention uses is: its heating sheet of the filter paper pretreating device of this structure is according to Temperature and Humidity mould
Temperature and humidity pair before filter paper measured by block during the epidemic disaster and particle sampling of ambient enviroment in sampling channel
Than, the heated condition of real-time control heating sheet, thus guarantee that filter paper is consistent with environment locating when sampling before sampling, Jin Erbao
The accuracy counted is demonstrate,proved, the final monitoring accuracy of ray method particle monitoring instrument is improved.
Detailed description of the invention
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is the face A-A cross-sectional view of the invention.
It is as shown in the figure: 1 U-shaped seat, 2 baffles, 3 bearing mounting bases, 4 roller bearings, 5 body frames, 6 Temperature and Humidity modules, 7
Fixed cover, 8 heating sheets, 9 supports, 10 rolling bearings, 11 filter paper.
Specific embodiment
Below with reference to Fig. 1 and Fig. 2, the present invention is described further.
As shown, embodiment 1, a kind of filter paper pretreating device for ray method particle monitoring instrument, including U-shaped seat
1, it is connected with support 9 on the U-shaped seat 1, heating sheet 8 is connected with by fixed cover 7 on the support 9；9 two sides of support point
Not She You bearing mounting blocks 3, roller bearing 4 is equipped on the bearing mounting blocks 3, the roller bearing 4 is affixed U-shaped by rolling bearing 10
Seat 1；The top of the heating sheet 8 is equipped with Temperature and Humidity module 6.
There are two roller bearings 4, roller bearing 4 to make for guaranteeing that filter paper 11 steadily moves in moving process for installation in U-shaped seat 1
The spacing that filter paper 11 and heating sheet 8 are kept constant, in order to enable heating sheet to the quick heating and dehumidification of filter paper, on filter paper and heating sheet
The distance on surface is designed as 2mm.Roller bearing 4 is fixed in U-shaped seat 1 by rolling bearing 10, and rolling bearing 10 is for reducing friction.
Close to the top of filter paper 11 in U-shaped seat 1, there are the Temperature and Humidity module 6 for detecting 11 ambient enviroment temperature and humidity of filter paper, the mould
Block can temperature, humidity to 11 upper peripheral of filter paper measure simultaneously.
It preferably, is the rapidity for guaranteeing heating, and the accuracy of detection.The temperature of the present embodiment Temperature and Humidity module 6
Degree, humidity sensor probe are located at apart from filter paper 2mm, and filter paper is 2mm at a distance from heating sheet upper surface.
Preferably, to guarantee that the high efficient and reliable of heating sheet uses, heating sheet is ceramic heating flake, and maximum heating temperature is
