Abstract
A simple dust sampler for collecting dust sample consists of a drum [1] with fixed diameter and a filter membrane box [2], wherein, the filter membrane box [2] is arranged on the bottom part; the outside diameter of the drum [1] is consistant with the inside diameter of the filter membrane box [2], so the drum [1] can be inserted into the filter membrane box [2]. Dust in the air can vertically fall on a filter membrane at the bottom of the sampler through the drum [1], and the amount of dust in the air within a certain time in a dust operation area can be detected according to the weight gain of the filter membrane.
Description
Affiliated technical field
The utility model relates to a kind of sampling apparatus of measuring dust content in the air.
Background technology
The general at present dust sampler that uses is made up of apparatus subject, tripod, FC-2A power supply three parts, and apparatus subject is made up of membrane pump, cadmium-nickel accumulator, flow control valve, flowmeter, sampling head that micromotor drives.During sampling filter membrane is placed on the sampling head by filter membrane clip, allow a certain amount of air that contains dust by filter membrane, the dust detention comes Dust Capacity in the analytical unit volume according to the weightening finish of filter membrane on filter membrane.There are some drawbacks in this method: instrument weighs greatly, carries inconvenience; The service condition height needs power supply; When dust concentration was high, the dust detention influenced the flow of sampling thief on filter membrane, make measurement result that deviation be arranged; Little when big during dust concentration in the production environment, generally sampling was difficult to accurately estimate air-borne dust content in 3～5 minutes.
Summary of the invention
In order to overcome the deficiency of existing dust sampler, the utility model provides a kind of simple and easy dust sampler, and it can not only accurately estimate the amount of dust in the every workday air, and easy to carry, does not need power supply during use, and is not fragile.
The technical scheme that its technical matters that solves the utility model adopts is: adopt a drum [1] to link to each other with a filter membrane box [2], during use, filter membrane is placed filter membrane box bottom, connect drum [1] and filter membrane box [2], level places the representative several position of working environment then, dust constantly drops on the filter membrane, through a working day, take out filter membrane, measure the filter membrane weightening finish, try to achieve mean value, reach the purpose of Dust Capacity in the air of accurate evaluation dust work place.
The beneficial effects of the utility model are, measure the amount of each worker with dust in the air in a few days accurately and easily, use simply, easy to carry, are specially adapted to occupational health prophylactico-therapeutic institution of basic unit and enterprise and test oneself.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is further specified.
Fig. 1 is an outside drawing of the present utility model.
Fig. 2 is a upper diagram of the present utility model.
Fig. 3 is a bottom diagram of the present utility model.
1. drums among the figure, 2. filter membrane box.
Embodiment
Put into the filter membrane of having weighed in filter membrane box [2] bottom, drum [1] is vertically inserted in the filter membrane box [2], level places the environment that contains dust, dust settling is on filter membrane, through a working day, take out filter membrane, measure the amount of dust in the powder method air of workplace according to the weightening finish of filter membrane.
Claims (3)
1, a kind of simple and easy dust sampler, its top are the drum [1] of a fixed inner diameter, and the bottom is filter membrane box [2], it is characterized in that: drum [1] inserts base filter membrane box [2] on top.
2, device according to claim 1 is characterized in that: drum [1] does not seal smooth surface up and down.
