Description
Technical field:
The present invention relates to a kind of air microbe and detect device for filtering and collecting, be specially adapted to air microbe and detect or inspection.
Background technology:
Microorganism that is of a great variety, substantial amounts is there is in environment around us, no exception in air.Although air is not the good environment that microorganism perches, due to the flowing of air-flow, dust and foam, the reasons such as the activity of humans and animals, still have a considerable amount of microorganism to exist.
Air is the material conditions that the mankind keep normal activity, and have extremely close relation with people's generic key health, along with society enters the information age, air microbe sampling detects and have also been obtained develop rapidly, develop all kinds of air microbe detecting instrument, need first to collect air sample when detecting air microbe, it is fine that existing air microbe detects collection device function, but often containing hair in the air sucked by induced draught fan, feather, the impurity such as the end of a thread, meeting blockage detector, cause proofing unit malfunctioning or be damaged, or the large particulate matter in air impacts detected result due to reason such as distinctive weight or volume itself, cause detected result inaccurate.
Summary of the invention:
The object of the invention is to overcome above deficiency, provide a kind of structure simple, easy to operate, cost of investment is low, and detected result preparation is high, and a kind of air microbe that can prevent instrument from blocking detects device for filtering and collecting.
Object of the present invention is achieved through the following technical solutions: a kind of air microbe detects device for filtering and collecting, comprise proofing unit, air intake device and collection device, proofing unit is connected by web member with air intake device, air intake device is made up of sleeve and fan, the first filtering net is provided with in sleeve with fan junction, proofing unit is made up of U-tube and plug, U-tube one end is connected with web member, the other end is connected with plug, U-tube and plug connecting place are provided with graduated scale, proofing unit is connected by communicating pipe with collection device, communicating pipe is provided with valve, collection device is made up of receiving flask and vacuum-pumping tube, vacuum-pumping tube is provided with check valve, receiving flask bottleneck is provided with a circle rubber seal.
Further improvement of the present invention is: communicating pipe outer wall be provided with a circle fixture block, and fixture block is arranged on below valve.
Further improvement of the present invention is: be provided with the second filtering net in web member.
The present invention compared with prior art has the following advantages:
Vibrational power flow of the present invention is simple, cost of investment is low, owing to being provided with the first filtering net with fan junction in sleeve, can effectively prevent the end of a thread in air, macrobead etc. from entering in proofing unit, be provided with the second filtering net in web member, double medium filtration, greatly strengthen filtering function, effectively prevent the blocking of proofing unit, and in turn ensure that the accuracy of detected result.Receiving flask bottleneck is provided with a circle rubber seal, prevents outside air to enter in receiving flask, thus pollutes collection sample.Communicating pipe, outer wall was provided with a circle fixture block, can firmly proofing unit was fixed on collection device, ensure that the carrying out of collection work.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Number in the figure: 1-proofing unit, 2-air intake device, 3-web member, 4-sleeve, 5-fan, 6-first filtering net, 7-U type pipe, 8-plug, 9-graduated scale, 10-communicating pipe, 11-valve, 12-collection device, 13-receiving flask, 14-vacuum-pumping tube, 15-check valve, 16-rubber seal, 17-fixture block, 18-second filtering net.
Embodiment:
In order to deepen the understanding of the present invention, below in conjunction with example and accompanying drawing, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
Device for filtering and collecting is detected as Fig. 1 shows a kind of air microbe of the present invention, described a kind of air microbe detects device for filtering and collecting and comprises proofing unit 1, air intake device 2 and collection device 12, proofing unit 1 is connected by web member 3 with air intake device 2, air intake device 2 is made up of sleeve 4 and fan 5, the first filtering net 6 is provided with in sleeve 4 with fan 5 junction, proofing unit 1 is made up of U-tube 7 and plug 8, U-tube 7 one end is connected with web member 3, the other end is connected with plug 8, U-tube 7 and plug 8 connecting place are provided with graduated scale 9, proofing unit 1 is connected by communicating pipe 10 with collection device 12, communicating pipe 10 is provided with valve 11, collection device 12 is made up of receiving flask 13 and vacuum-pumping tube 14, vacuum-pumping tube 14 is provided with check valve 15, receiving flask 13 bottleneck is provided with a circle rubber seal 16, communicating pipe 10, outer wall was provided with a circle fixture block 17, and fixture block 17 is arranged on below valve 11, the second filtering net 18 is provided with in web member 3, this vibrational power flow is simple, easy to operate.
A kind of air microbe of the present invention detects the use principle of device for filtering and collecting: before use, receiving flask 13 is connected with communicating pipe 10 by rubber seal 16, fixture block 17 is sitting on receiving flask 13, valve-off 11, then check valve 15 is opened, by vacuum-pumping tube 14, the air in receiving flask 13 is drained only, ready, closing one-way valve 15.Then air intake device 2 is started, by fan 5 by air intake, during by the first filtering net 6, first filtering net 6 is isolated by the feather in air, the end of a thread, macrobead etc., and when then air is to web member 3, the second filtering net 18 filters air again, air intake is in proofing unit 1, fully contact with the liquid in proofing unit 1, the graduated scale 9 on proofing unit 1 can be measured well, measures the content of microorganisms in unit liquid.Measure complete, close air intake device 2, open valve 11, liquid was collected in receiving flask 13 by communicating pipe 10, collected complete.
