Description

A kind of microorganism sampler for collecting different-grain diameter

Technical field

The utility model belongs to mechanical equipment technical field, and in particular to a kind of microbe sampling for collecting different-grain diameter Device.

Background technology

Six grades of air microorganism samplers are six grades of sieve pore impacting type air microorganism samplers, are a kind of difunctional stepwises Multistage hits sampler, can be widely used in monitoring in the environment such as health and epidemic prevention, biologic cleanliness, pharmacy, fermentation industry and Make the sampling research of air microbe in relation to research teaching department, (six grades) of air microorganism sampler is micro- for evaluation air environment Biological pollution harm and its control measure provide foundation.Six grades of sieve pore impacting type air microorganism samplers are in addition to that can measure sky Except the quantity of gas microorganism, its exclusive characteristic can also measure the size of these particles, and the latter is judgement air microbe One of important indicator of harm.It is combined into one by six rams, is really a single-stage sampler per level-one, is utilized 6 collision theories repeatedly, most particles are especially the particle settled in tracheae and lung and all hit substantially, thus it is adopted The particle size range collected is wider naturally than single-stage, this be some single-stages hit sampler it is incomparable, and sample The circular spout of device has higher sampling efficiency than spouts such as cracks.Relative humidity increases step by step (by the first order when sampling 39% increases to the 88% of the 6th grade), this is advantageous to fragile pathogenic microorganism, the especially survival of virion.Due to Its these unusual feature, makes it wide and practical be applied to the monitoring of air microbe, and since the advent of the world is common not It declines.International standard sampler is recommended as by expert.The anatomical structure and sky of six grades of air microorganism sampler simulation human respiratories Aerodynamics physiological characteristic, samples inertial impaction principle and the aerial microorganism particle that will suspend hierarchically is collected into and adopts On sample dielectric surface, then for culture and microbiologic analysis.

Use principle：Ram is 6 layers of aluminium alloy disk for having small eyelet.Disk transfers agar plate, often between disk There is sealing rubber ring, disk is being linked togather securely by three spring carrier arms.Have on each disk 400 at belt row Row successively reduce, and standard sample flow is 1 cube of Foot (28.3L/min).When the air-flow containing microorganism particle enters top layer Thief hatch after, due to successively increasing for air-flow, different size of microorganism ion aerodynamically feature impinges upon respectively On corresponding agar surface.The particle size range captured at different levels is by the grain of the air velocity and upper level of this grade of eyelet Son cuts resistance rate and determines.The particle that the upper respiratory tract of first and second grade of similar people captures, the lower respiratory tract of 3-6 grades of similar people The particle of capture, this just substantially replicates these particles in the penetration of respiratory tract and calm position.Six grades of air Microorganism sampler can provide the plate for having installed ordinary nutrient agar additional.

Now in order to facilitate the air microbe for collecting different-grain diameter size, convenient design is provided for the research of air environment A kind of microorganism sampler for collecting different-grain diameter.
