Abstract
The utility model discloses a multilayer synchronous air dust simple sampler which is composed of powder dust sampling heads (1), a flow meter (5) and an extraction pump (2). The flow meter (5) is equipped in the connecting pipeline (3) of the powder dust sampling heads (1). The utility model is characterized in that three powder dust sampling heads (1) are equipped and communicated with the inner chamber of a negative pressure tank (4) through the connecting pipeline (3) which is provided with the flow meter (5). The three powder dust sampling heads (1) are arranged in a vertical line and the distance between every two adjacent powder dust sampling heads (1) is 100 cm. The negative pressure tank (4) is connected with the miniature extraction pump (2) through the pipeline. The multilayer synchronous air dust simple sampler not only has a simple structure and convenient usage but also enables a three-level sampling, namely, the high, middle and low levels simultaneously and further enhances the detecting precision of air dust content.
Description
Technical field
The utility model relates to a kind of improvement of air dust sampler, and the simple and easy sampling thief of the synchronous air-borne dust of specifically a kind of multilayer is applicable to the dusty gas sampling of atmosphere or large space.
Background technology
The air-borne dust sampling is an important process of health and epidemic prevention department, is mainly used to analyze airborne dust content, to determine the harm to the people.At present, employed air dust sampler comprises micromachine, membrane pump, flowmeter, sampling head and filter membrane, during sampling mostly, need add filter membrane and be held on the sampling head, sampling head connects flowmeter and membrane pump successively, drives membrane pump by micromachine and sampling head is bled the airflow filtering membrane, dust deposit is on filter membrane, weighing by filter membrane relatively draws weightening finish, then according to flow, and the dust content in can the unit's of calculating volume of air.The deficiency of this air dust sampler is: because dust granules is not of uniform size, it is higher that thin dust often suspends, and thick dust is toward sinking, and present air dust sampler can only be surveyed a level at every turn, or point, can not be simultaneously, with the pacing many levels, cause detecting not comprehensive.If multi-point sampling, because air-borne dust content is not only because of highly changing, and difference in time also changes, so, since asynchronous, just be easy to generate analytical error.
Summary of the invention
The purpose of this utility model is to provide a kind of can carry out air sampling at many levels, simultaneously, synchronously, thereby further improves the simple and easy sampling thief of the synchronous air-borne dust of multilayer of air-borne dust accuracy of detection.
For reaching above purpose, the technical scheme that the utility model adopted is: the simple and easy sampling thief of the synchronous air-borne dust of this multilayer, by the dust sampling head, flowmeter and aspiration pump constitute, flowmeter is installed on the connecting tube of dust sampling head, it is characterized in that the dust sampling head establishes three, the connecting tube by flowmeter is installed and the intracavity inter-connection of negative pressure box respectively, three dust sampling heads are arranged on the perpendicular line, distance between the adjacent dust sampling head is 100cm, and a following dust sampling head overhead highly is 50cm, negative pressure box is connected with micro-suction pump by pipeline, by the even negative pressure in the micro-suction pump realization negative pressure box.The utility model is also implemented by following measure: described dust sampling head is made of cylindrical shell and filter membrane box, puts into the filter membrane of having weighed in the bottom of filter membrane box, and cylindrical shell inserts in the filter membrane box; Bottom at negative pressure box is provided with support; Support, connecting tube and aspiration pump are flexible connection.
The beneficial effects of the utility model are: compare with the air dust sampler of present use, not only simple in structure, easy to use, and it can be sampled from high, medium and low three levels synchronously, simultaneously, thereby has further improved the accuracy of detection of air-borne dust content.
