Description
Technical field
The utility model belongs to dust collection equipment field, is specifically related to a kind of dust sampler.
Background technology
The dust sampler that environmental monitoring technology field often uses at present is generally made up of apparatus subject, A-frame, this three part of power supply, and the membrane pump that apparatus subject is driven by micromotor, cadmium-nickel accumulator, flow control valve, flowmeter, sampling head form.During sampling, filter membrane is placed on sampling head by filter membrane clip, a certain amount of air containing dust is allowed to pass through filter membrane, dust detention is on filter membrane, the Dust Capacity in analytical unit volume is carried out according to the weightening finish of filter membrane, the defect that above-mentioned method exists is, instrument is comparatively large and heavy, carry inconvenience, be unsuitable for spot sampling, and above-mentioned appliance requires provides power supply, when dust concentration content height, dust detention is on filter membrane, affect the flow of sampling thief, measurement result is made to have deviation, little time large during dust concentration in production environment, the content of general sampling 3-5 minute very difficult accurate evaluation dust in air.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides the dust sampler that a kind of volume is little, need not provide external power supply, be suitable for spot sampling.
Dust sampler of the present utility model is realized by following technical proposals:
A kind of dust sampler, comprise dust sampling head, the base that described dust sampling head comprises cylindrical shell and matches with cylindrical shell, this cylindrical shell is Rotary-table, the cross-sectional area of described cylindrical shell bottommost and cylindrical shell topmost cross-sectional area ratio be 1:3-5; The diameter of the xsect of cylindrical shell bottommost is 1:3-6 with the ratio of the height of cylindrical shell; Dust sampling head is connected with dust sampling flowmeter.
Base is the uncovered cylinders in top and the bottom, base and cylindrical shell clamping, and go to the bottom the most diameter compatible of xsect of the diameter of base and cylindrical shell closes;
Have filter membrane I above base, filter membrane I diameter is identical with the diameter of cylindrical shell bottommost xsect;
The cover matched with cylindrical shell is arranged at cylindrical shell top, and cover centre has connector, and connector is connected with dust pre-capture device, has filter membrane II in described dust pre-capture device;
The aperture of filter membrane II is greater than the aperture of filter membrane I, and filter membrane II pair of dust tentatively filters and collect, and when the dust dropped on filter membrane I through filter membrane II is collected by filter membrane I, such as filter membrane I can collect the particles such as PM2.5, realizes collecting the layering of dust.
The bottom of described base is fixedly connected with Connection Block.Be connected with dust sampling flowmeter by Connection Block.
Cylindrical shell is glass material.Cover is anti-aging rubber material.Filter membrane is quartzy microfibril filter membrane or PTFE film.
The beneficial effects of the utility model are, have employed the dust sampler of said structure, its dust sampling head advantage is that volume is little, be easy to carry and on-the-spot quick collection, in addition owing to being provided with dust pre-capture device and filter membrane II on sampling thief, on the base of sampling thief, be provided with filter membrane I again, can realize collecting the layering of dust, bulky grain and short grained dust are collected respectively and calculates and statistics.
