Phytoplankton sampler for air quality detection

Abstract

The invention provides a phytoplankton sampler for air quality detection, wherein the phytoplankton sampler includes a base, a suction fan, a shunt suction pipe, a top cover, transparent plates, sampling heads, a filter plug, a top seal plate, an insert slot, a rotary knob and a partition plate; the base is of a rectangular cavity base structure, and an electrical box with an operation panel is mounted on the left side of the top surface of the base; the suction fan is mounted vertically on the top surface of the base, and the suction fan is electrically connected with the electrical box through an electric connecting wire; a suction inlet of the top surface of the suction fan is connected with a gas inlet chamber having a circular cavity structure. Because the device has four workstationchambers, gas absorption and collection of single or a plurality of workstations is achieved under a controllable work environment, multi-workstation observation of the microbial adsorption culture inair can be achieved, and comparison is obtained by a detection means of microbial absorption in gas in the workstation chambers in the prior art.

Description

technical field [0001] The invention belongs to the technical field of sample gas collection devices, and more specifically relates to a planktonic bacteria sampler for air quality detection. Background technique [0002] The air planktonic sampler is generally designed according to the Anderson impact principle. The suction device of the instrument sucks the air through the porous sampling head and impacts it on the Φ90mm petri dish, and the microorganisms in the air are "captured" on the agar medium. The sampler is widely used in pharmaceutical industry, food industry, beverage tap water, drug inspection institute, sanitation and epidemic prevention, hospital, public places and other related industries and departments. [0003] The inventor found similar patents for tree injection in the process of searching for patents. For example, the application number is: CN201720210235.2, which involves a sampler for planktonic bacteria, which is basically described as: including a s...

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a sampler for airborne bacteria for air quality detection, to solve the above-mentioned existing airborne bacteria sampler similar to the above-mentioned structure, which is mainly composed of a petri dish, and cannot realize multi-acquisition For comparative testing, and after the collection head is used for a period of time, a large amount of accumulated bacteria will be produced on the surface. When the collection head is used to suck the sample gas from the air, a certain amount of accumulated bacteria will enter the petri dish, which will affect the quality of the test.
