Description
Technical field
This utility model relates to safe biologic cabinet technical field, specifically a kind of bactericidal unit for safe biologic cabinet.
Background technology
So-called Biohazard Safety Equipment is to be operation primary culture, when bacterium strain and diagnostic specimen light fixture have infective test material, be used for protecting operator, laboratory environment and test material, make it avoid being exposed to issuable laboratory infection and culture cross-contamination in aforesaid operations process, Biohazard Safety Equipment also can be protected working environment simultaneously, the pathogenic microorganism diffusion personnel that cause that prevent operation injure and environmental pollution, it is provided with cabinet, safety guard, workbench, for wind filter and blower fan, bottom of cabinet bulk is provided with workbench and air inlet, top is provided with for wind filter and blower fan, cabinet front side is provided with safety guard, air inlet on cabinet is provided with for wind filter, be connected with the exhaust manifolds on cabinet through blower fan for wind filter, its principle is by supplying wind filter by after harmful substance filtering, by exhaust system by filter after Bas Discharged outside laboratory, reduce because aerosol exposes the laboratory infection and the culture cross-contamination that cause, its deficiency is: owing to supplying wind filter in long-term work, its inner filter element has gathered a large amount of antibacterials, and by its parcel, and lose the function of sterilization, therefore, be easy to contaminated environment again through the gas being discharged in external environment condition for wind filter.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and a kind of simple in structure, sterilize thorough, reliable, the safe bactericidal unit for safe biologic cabinet of filter sterilization are provided.
This utility model solves the technical scheme that its technical problem adopts:
A kind of bactericidal unit for safe biologic cabinet, be provided with cabinet, cabinet top is provided with exhaustor, the air inlet of exhaustor is provided with for wind filter, for connecting fan on the exhaustor of wind filter outside, it is characterized in that for being provided with sterilizing cylindrical shell between wind filter and air inlet, in described sterilizing cylindrical shell, be provided with helical duct, sterilizing cylindrical shell lower sides is connected with steam pipe, the steam pipe other end is connected with vaporium, described vaporium is fixed on cabinet, in vaporium body, be provided with disinfectant solution, vaporium top is provided with liquid filling hole and vapor opening, vaporium sidewall is provided with liquid level sensor and temperature sensor, vaporium bottom is provided with heater, described liquid level sensor, temperature sensor is connected with the control system on cabinet respectively with heater, described vapor opening is connected with steam pipe, be beneficial in the time of work, heater, disinfectant solution in vaporium starts heating and is evaporated, steam enters sterilizing cylindrical shell through steam pipe, in sterilizing cylindrical shell along moving on screw channel, simultaneously, contaminated air in cabinet is under the effect of blower fan, enter screw channel through air inlet, converge with the steam in screw channel, after making it to merge completely and kill by screw channel, again through the filtration again for wind filter, make blower fan expellant gas reach safe standard, avoid the gas being contaminated by bacterial to be discharged to contaminated environment in air.
This utility model is owing to adopting said structure, have simple in structure, sterilization thoroughly, the advantage such as reliable, the safety of filter sterilization.
brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Reference numeral: cabinet 1, exhaustor 2, air inlet 3, confession wind filter 4, blower fan 5, sterilizing cylindrical shell 6, helical duct 7, steam pipe 8, vaporium 9, liquid filling hole 10, vapor opening 11, liquid level sensor 12, temperature sensor 13, heater 14.
Detailed description of the invention:
Below in conjunction with accompanying drawing, this utility model is further illustrated:
As shown in drawings, a kind of bactericidal unit for safe biologic cabinet, be provided with cabinet 1, cabinet 1 top is provided with exhaustor 2, the air inlet 3 of exhaustor 2 is provided with for wind filter 4, for connecting fan 5 on the exhaustor 2 of wind filter 4 outsides, it is characterized in that for being provided with sterilizing cylindrical shell 6 between wind filter 4 and air inlet 3, in described sterilizing cylindrical shell 6, be provided with helical duct 7, sterilizing cylindrical shell 6 lower sides are connected with steam pipe 8, steam pipe 8 other ends are connected with vaporium 9, described vaporium 9 is fixed on cabinet 1, in vaporium 9 bodies, be provided with disinfectant solution, vaporium 9 tops are provided with liquid filling hole 10 and vapor opening 11, vaporium 9 sidewalls are provided with liquid level sensor 12 and temperature sensor 13, vaporium 9 bottoms are provided with heater 14, described liquid level sensor 12, temperature sensor 13 is connected with the control system on cabinet 1 respectively with heater 14, described vapor opening 11 is connected with steam pipe 8.
This utility model is in the time of work, first heater 14, when temperature in vaporium 9 is responded in temperature sensor 13 reaches 90 °, control system starts blower fan 5 and supplies wind filter 4, operator starts working, disinfectant solution in vaporium 9 starts heating and is evaporated, steam is in steam pipe 8 enters sterilizing cylindrical shell 6, interior along moving on screw channel 7 at sterilizing cylindrical shell 6, simultaneously, contaminated air in cabinet 1 is also under the effect of blower fan 5, enter screw channel 7 through air inlet 3, fully converge with the steam in screw channel 7, and the fusion that extends contaminated air and steam by the screw action of screw channel 7, after medicine in steam is killed the antibacterial in contaminated air completely, again through the filtration again for wind filter 4, make blower fan expellant gas reach safe standard, avoid germy air to be discharged to outside and contaminated environment, disinfectant solution in liquid level sensor 12 senses vaporium 9 reaches specifies lower prescribing a time limit, control system is reported to the police, operator can add disinfectant solution by liquid filling hole in vaporium.
