Description
Technical field
The present invention relates generally to bio-safety field of purification, is specifically related to a kind of Biohazard Safety Equipment of Real-Time Monitoring filter leaks.
Background technology
At laboratory operation liquid or semifluid, such as to shake, pour into, stir or fluid drips is added on the surface of solids or in another kind of liquid time, may aerosol be produced.And to agar plate streak inoculation, with suction pipe inoculating cell blake bottle, to infection liquid carry out centrifugal and carry out animal operation time, these laboratory operation all may produce aerosol.The diameter cannot seen for these naked eyes is less than the fine liquid that the aerosol of 5 microns and diameter are 5 μm ~ 100 μm, and laboratory worker can not recognize their existence usually, and may suck or the other materials of cross pollution work top.
Biohazard Safety Equipment be for operation primary culture, bacterium strain and diagnostic sample etc. there is infective experiment material time; be used for protection operator, laboratory environment and experiment material, make it avoid being exposed to issuable infectious aerosol and spatters in aforesaid operations process and design.
Its principle is by after harmful substance filtering by filter; by exhaust system, the air after filtering to be discharged in the laboratory outside or partly to turn back to work top; reduce because aerosol exposes the laboratory infection and culture cross pollution caused; and protection of the environment, prevents the pollution of the environment.
The pure air that Biohazard Safety Equipment provides is exactly mainly rely on the filtration of high efficiency particulate air filter to realize, so the leakage of filter or its integrality are vital for the security of Biohazard Safety Equipment.Traditional Biohazard Safety Equipment can only do a detection when initial installation, cannot ensure the integrality of its filter in follow-up use procedure constantly.If leaked, just can not provide the environment of a safety clean, continuing use can exist security risk.
Summary of the invention
The object of the present invention is to provide a kind of Biohazard Safety Equipment realizing the Real-Time Monitoring filter leaks of leak detection to vertically passing filter.
For solving the problems of the technologies described above, the Biohazard Safety Equipment of Real-Time Monitoring filter leaks of the present invention, comprising: cabinet, is provided with air outlet on described cabinet top; Blower fan, described blower fan is arranged on described cabinet internal upper part; Negative pressure channel, described negative pressure channel is arranged on the rear outside of described cabinet, and one end of described negative pressure channel is arranged on below described cabinet, and the other end of described negative pressure channel extends to the top of described cabinet along described cabinet rear portion; Detection architecture, described detection architecture is arranged in described cabinet, is positioned at the top of described cabinet workspace; Wherein said detection architecture comprises: scanning mobile platform, and described scanning mobile platform is arranged in described casing, is positioned at top, described cabinet workspace; Mobile unit, described mobile unit is arranged in described scanning mobile platform; Scanning head, described scanning head is arranged in described mobile unit.
Described mobile unit comprises: horizontal guide groove, and two described horizontal guide grooves are arranged on described scanning mobile platform inwall in opposite directions; Longitudinal rail, the two ends of described longitudinal rail are embedded in two described horizontal guide grooves respectively.
Described scanning head is arranged on described longitudinal rail.
In described cabinet, be also provided with homogenizing plate, described homogenizing plate is positioned at top, described cabinet workspace, is positioned at below described detection architecture.
Between described blower fan and described cabinet bottom and exit, described negative pressure channel top be provided with filter.Described filter is high efficiency particle air filter.
The Biohazard Safety Equipment of Real-Time Monitoring filter leaks of the present invention by installing detection architecture in workspace, the probe detecting cleanliness factor is fixed on a moving track in detection architecture, probe can move in orbit, make in the actual use of workbench, cleanliness factor detection probe is lined by line scan along track, realizes leak detection, when finding that there is leakage and existing, can real time output, enable equipment send the timely Inspection and maintenance of sound and light alarm signal prompt operating personnel timely.
