Description
Technical field
The utility model relates to a kind of poidometer, relates in particular to a kind of particle in atmosphere and filter membrane poidometer of suspended particulate substance of detecting.
Background technology
P is the particulate(particulate) first letter, M is the matter(material) first letter, PM2.5 is the particle general name that in atmosphere, particle diameter is equal to or less than 2.5 μ m, PM10 is the particle general name that in atmosphere, particle diameter is equal to or less than 10 μ m, the abbreviation of the English total suspended of TSP particulate, be total suspended particles, claim again overall suspended pellet.The gross mass particle diameter of finger is collected with the large capacity particle of standard collector on filter membrane particle is less than the TSP that is called of 100 μ m, i.e. total suspended matter particle.
At present, country monitoring PM10, PM2.5 only mainly contains these three kinds of gravimetric methods, micro-oscillating balance method, β rays method.Environment TSP, PM10, PM2.5 method of testing that physics and chemistry detects in industry are mainly the operating weight weighing methods, are exactly to adopt the forward and backward weight difference of test filter membrane sampling to calculate airborne pollutant levels.PM10, the monitorings such as PM2.5 are regular monitorings in environmental monitoring, the sample collector places sampling pump to sampled point, use Special filtering membrane, the aspiration pump of a steady flow produces negative pressure, the gas that contains the fine particle pollutant passes through filter membrane, particle is trapped, by weighing after constant temperature, obtain a result, filter membrane weighing workload maximum in observation process, because of its technology gold content not high, operation is dull, need to carry out specially with manpower, time has been grown operating personnel and has easily produced tired, spirit is absent minded, easily make mistakes, affect the monitoring result accuracy, reduce work efficiency.
Trace oscillating balance method is used a vibration hollow conical pipe in mass sensor, at its vibration end, removable filter membrane is installed, oscillation frequency depends on tapered tube feature and its quality, when sampling air flow passes through filter membrane, particle wherein is deposited on filter membrane, the mass change of filter membrane causes the variation of oscillation frequency, by the oscillation frequency change calculations, goes out to be deposited on the quality of particle on filter membrane, then according to flow, site environment temperature and air pressure, calculates the mass concentration of this period particle sign.
The Beta rays method, utilize the principle of Beta ray attenuation, surrounding air sucks sampling pipe by sampling pump, after filter membrane, discharge, particle is deposited on filter membrane, when depositing the filter membrane of particle, the energy attenuation of Beta ray, just can calculate the concentration of particle by the mensuration to damping capacity when the β ray.Above three kinds of auto monitoring and measurement instrument are expensive, and general unit also can not buy several, and cost is higher, move also inconvenient.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, the work of employing automatic weighing machine, the microcomputerized control bracket move to the sample applier next lattice under, micro computer is controlled the bracket rising again and is held up filter membrane, by the tangential movement device, move and send a telegraph directly over sub-balance, the vertical motion device falls filter membrane is stayed on electronic balance by vertical link motion, until microcomputer-measuring and after recording weight, the microcomputerized control bracket is put back to the sample applier to filter membrane according to original route, whole process is that micro computer records weighing data, realize the full-automatic weighing of filter membrane, convenient and swift, data are accurate.
The purpose of this utility model is realized by following technical scheme, developed a kind of filter membrane poidometer, comprise shell 1, sample applier upper cover 2, sample applier 3, it is characterized in that: described sample applier 3 surroundings are inserted in shell 1, sample applier 3 upper surfaces arrange sample applier upper cover 2, and sample applier 3 vertically arranges waling stripe 6.
Described waling stripe 6 is connected with vertical motion device 5, and vertically connecting rod 4 inserts in vertical motion device 5, and vertically connecting rod 4 is mutually vertical with waling stripe 6, and waling stripe 6 is vertically sliding on connecting rod 4 by vertical motion device 5.
On described waling stripe 6, tangential movement device 7 is set, tangential movement device 7 is connected with bracket 8.
Described bracket 8 is circular arc.
Described vertical connecting rod 4 low sides are fixedly connected with electronic balance 9.
Advantage of the present utility model: simple in structure, design science, the whole process micro computer of the full-automatic weighing of filter membrane records weighing data, convenient and swift, data are accurate, avoid the manual weighing personal error to occur, move simultaneously conveniently, automatic weighing, reduce labor intensity and increase work efficiency.
