Description
Technical field
Environmental technology field is the utility model is related to, more particularly to a kind of aerosol collection pressure setting.
Background technology
With the continuous development of national state control network radiation environmental monitoring work, the monitoring work of radionuclide in aerosol
Make more important；Because environmental aerosols sample size is significantly increased, constituent parts compete for the high spectrometer of detection efficient, but are composed
Instrument resource constraint；Low energy γ nucleic detection limit requires to improve particularly in aerosol, aerosol sample volume and time of measuring with
Increase；Certain difficulty is caused to spot sampling work and lab analysis work.The compacting of aerosol filter membrane, detection efficient
Optimization that calculating and time of measuring, detection limit etc. is all the urgent problem to be solved in gasoloid, and aerosol pressure-like is set
Standby performance and parameter has very important effect in the work of aerosol radioactivity monitoring, and downtrodden aerosol sample is put
Easily bounce-back occurs for the time for putting certain length, it is necessary to which the sample of repetition measurement is because height changes and detection efficient need to be repaiied
Just；
The collection of aerosol at present mainly gathers two kinds by gravity-flow ventilation collection and artificial convection, passes through aerosol filter membrane
Naturally absorption has the problems such as efficiency is low, the time is long.
For further specification and national radiation environmental monitoring work is improved, Chinese Ministry of Environmental Protection is to national radiation environmental monitoring scheme
In the horizontal requirement of aerosol sample Monitoring Data improving constantly, the pre-treatment work of aerosol sample seems particularly heavy
Will, however, the pre-processing device of aerosol sample and mode are all fairly simple extensive both at home and abroad at present, pre-treatment is mostly directly to roll over
Folded aerosol filter membrane is encapsulated into sample box or manually suppressed using manual aerosol sample-pressing device.The former, directly folds envelope
Dress method, easily expansion causes big volume change or Density inhomogeneity to aerosol filter membrane sample and standard substance is not easy to make；The latter,
Using manually compacting aerosol filter membrane is wasted time and energy and uniformity is bad.
Utility model content
The utility model is directed to the defects of prior art, there is provided a kind of aerosol gathers pressure setting, can effectively solve
Certainly the above-mentioned problems of the prior art.
In order to realize above purpose of utility model, the technical scheme that the utility model is taken is as follows：
A kind of aerosol gathers pressure setting, is made up of hydraulic press, shell, harvester.
The hydraulic press wraps fuselage by shell and has air-tightness, and case surface is provided with for being put into aerosol filter membrane
Door.
The harvester is made up of column and catch tray, and column bottom is erected at directly over shell, upper end and catch tray
Center connection.
The catch tray upper surface is provided with multiple Electrostatic Absorption disks, and the Electrostatic Absorption disk is used to place shape identical gas
Colloidal sol filter membrane simultaneously adsorbs aerosol.
Further, the grinding tool shape of the hydraulic press is identical with Electrostatic Absorption disk shape.
Further, the hydraulic press is provided with the volume that stopping means is used to control compacting aerosol filter membrane.
Further, the hydraulic press is provided with super-pressure safety valve, plays overpressure protection effect.
Further, the energization of the Electrostatic Absorption disk, which is realized, is connected with hydraulic press circuit, passes through the control of hydraulic press
Module realizes the power-off of Electrostatic Absorption disk and opens electricity, or is separately provided circuit plug and is connected with external circuit.
Compared with prior art the utility model has the advantage of：Substantially increased using hydraulic press compacting aerosol filter membrane
Sample preparation precision and efficiency, the press time of aerosol sample shorten.Harvester can quickly gather aerosol using electrostatic,
It is and more convenient with press device integral operational；Provided with shell and seal, prevent aerosol from being given out in pressing process
The dust come damages to operating personnel's body.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment；
Fig. 2 is the top view of the utility model embodiment catch tray.
Embodiment
For the purpose of this utility model, technical scheme and advantage is more clearly understood, develop simultaneously implementation referring to the drawings
Example, is described in further details to the utility model.
As shown in Figure 1, 2, a kind of aerosol collection pressure setting, is made up of hydraulic press 1, shell 2, harvester 3.
The hydraulic press 1 is wrapped fuselage and sealed by shell 2, and the surface of shell 2 is provided with for being put into aerosol filter membrane
Door.
The harvester 3 is made up of column and catch tray 4, and column bottom is erected at directly over shell, and upper end is with receiving
The center connection of catch basin 4.
The upper surface of catch tray 4 is provided with 6 Electrostatic Absorption disks 5, and the Electrostatic Absorption disk 5 is used to place shape identical
Aerosol filter membrane simultaneously adsorbs aerosol.
The energization of the Electrostatic Absorption disk 5 can be connected with the circuit of hydraulic press 1, and electrostatic is realized in the control module of hydraulic press 1
The power-off of suction tray 5 and electricity is opened, circuit plug can also be separately provided and be connected with external circuit.
The grinding tool shape of the hydraulic press 1 is identical with the shape of Electrostatic Absorption disk 5.
The hydraulic press 1 is provided with the volume that stopping means is used to control compacting aerosol filter membrane.
The hydraulic press 1 is provided with super-pressure safety valve, plays overpressure protection effect.
When in use, Electrostatic Absorption disk 5 is powered and places aerosol filter membrane, wait aerosol filter membrane above to adsorb enough
Aerosol after remove aerosol filter membrane, in the cavity plate of the overlapping grinding tool for being placed on hydraulic press 1, in setting pressure, dwell time
Under conditions of aerosol filter membrane is pressed into by round pie by extrusion forming.
One of ordinary skill in the art will be appreciated that embodiment described here is to aid in reader and understands this reality
With new implementation, it should be understood that the scope of protection of the utility model is not limited to such especially statement and implemented
Example.One of ordinary skill in the art can these technical inspirations according to disclosed in the utility model make and various do not depart from this reality
