Technical field
The utility model relates to a kind of measurement mechanism of dust concentration.
Background technology
Along with industrial expansion, the pollution of atmosphere is more and more serious, and the various dust that contain in the air are more and more, are drawn into by the people in the respiratory system of human body, can give rise to diseases the health of harmful to human.Therefore, in order to protect the healthy of people, all need to measure the concentration of dust in the air, so that take corresponding safeguard procedures in some specific places.
The applying date be on September 3rd, 2002 patent No. be to disclose a kind of simple and easy dust sampler that is used to gather the dust sample in the Chinese utility model patent instructions of ZL02269241.X, it is made up of drum and a filter membrane box of a fixed inner diameter, the filter membrane box is positioned at the bottom, the drum external diameter is consistent with filter membrane box internal diameter, and drum is just in time inserted in the filter membrane box.This sampling thief falls on the filter membrane of sampling thief bottom automatically by dust, detect in the certain hour of dust work place the amount of dust in the air according to the weightening finish of filter membrane, though it is simple in structure, but owing to be to fall into sampling thief automatically by dust to gather dust, acquisition time is long, measure inaccurately, can't realize automatic measurements and calculations.And in addition, the automatic detection instrument of a lot of dust concentrations is also arranged at present, but its complex structure, cost is higher.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of measurement mechanism of simple in structure, cost is low and automaticity is higher dust concentration.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of measurement mechanism of dust concentration, comprise control system, the air acquisition cavity, piston component and back-moving spring, described piston component is connected with the top seal of described air acquisition cavity, one end apical grafting of described back-moving spring is on described piston component, the other end of described back-moving spring is fixed, the bottom internal fixation of described air acquisition cavity is provided with filtering membrane, be connected with weight sensor on the described filtering membrane, described air acquisition cavity is provided with on the gas admittance valve and control air acquisition cavity of control air acquisition cavity and extraneous intercommunication, the channel valve of bottom intercommunication, described gas admittance valve is between described piston component and described filtering membrane, described channel valve is between described gas admittance valve and described filtering membrane, the lower ending opening of described air acquisition cavity, be connected with driving mechanism on the described piston component, described driving mechanism, gas admittance valve, channel valve and weight sensor all are electrically connected with described control system.
Described piston component comprises piston and the pressing plate that one connects, and described piston is connected with the top seal of described air acquisition cavity, and an end apical grafting of described back-moving spring is on the upper surface of described pressing plate.
