Description
Technical field
Widely used sterilizing installation in a kind of pharmaceutical industry is the utility model is related to, more particularly to a kind of hot air sterilization
Equipment.
Background technology
Hot air sterilization is that product is put in hot air box, using the oxidation of heated dry air, kills the micro- of all work
Biology or the method for eliminating thermal source.Each pharmacy corporation requires high to the hot-air cleannes entered in dry heat sterilization devices, all
It is the failure to enter the hot-air in chamber by high efficiency particle air filter, is unqualified.
Patent CN202236757U discloses a kind of dry heat sterilization cabinet, including cabinet, the air filtration being arranged in cabinet
Device, circulate in the wind machine and cavity, the air inlet of the cavity are connected with the air inlet of the air cleaner, the steel plate frame
Volume is more than the volume of air cleaner, the gap between the steel plate frame and the air cleaner and the suction of circulate in the wind machine
Air port is connected, and will be clamped and is fixed in cabinet with steel plate frame before and after air cleaner in cabinet, steel plate frame and air cleaner
Between gap be connected with the inlet scoop of circulate in the wind machine, so as to ensure dry heat sterilization cabinet at work, circulate in the wind machine operation
In negative pressure state, so as to improve sealing.
But circulated air is in the presence of circulating fan, the main cross section filter core of the high-efficiency air filter in transit chamber
Filtering, to the air persistent loop in dry heat sterilization devices, self-cleaning is filtered, during progressively reaching hundred grades of requirements of cleanliness factor,
Due to dead angle and lamina air flow flowing be present, partial air all the time be present can be not involved in circulating, and cause device memory not leading to
The air of high-efficiency air filter is crossed, the halfway hidden danger of sterilizing be present.
The content of the invention
The purpose of this utility model is：Circulation, which is not involved in, for partial air in above-mentioned dry heat sterilization devices being present causes
Sterilize halfway problem, and the utility model provides a kind of xeothermic going out that all air forced circulations can be reached to sterilizing requirement
Bacterium equipment.
The technical solution adopted in the utility model is as follows：
A kind of dry heat sterilization devices, including cabinet, the circulating fan being arranged on cabinet, high-efficiency air filter and chamber
Body, the cabinet are closed cabinet, and the circulating fan is provided with air inlet and air outlet, the air inlet and air outlet it
Between be provided with baffle plate, the cavity is provided with interlayer with bottom of cabinet bulk, and the high-efficiency air filter is arranged on cavity side, and air
High efficiency particulate air filter extends to cavity bottom, and blower fan is provided with the bottom of cavity opposite side.
Further, it is provided with temp probe in the cavity.
Further, heater is provided between the cabinet and cavity.
Further, the blower fan is frequency conversion fan.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
Cabinet of the present utility model is closed cabinet, the sky in incipient stage opening circulating fan, closed cabinet
Gas constantly by high-efficiency air filter, realizes the sterilizing to the air in cabinet, and by being set in the bottom of cavity side
There is blower fan, the power of blower fan is change, can force the air flow of the air-out side of cavity, realizes the turbulent flow fortune of air
It is dynamic, it is therefore prevented that form laminar motion from the air of cavity air-out side, eliminate exist partial air be not involved in all the time circulation,
The repeatedly halfway hidden danger of air sterilization of circulation rear chamber side.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model；
Marked in figure：1- circulating fans, 2- air outlets, 3- baffle plates, 4- cabinets, 5- high-efficiency air filters, 6- temperature are visited
Head, 7- cavitys, 8- blower fans, 9- air inlets.
Embodiment
The present invention is elaborated with reference to Fig. 1.
As shown in figure 1, a kind of dry heat sterilization devices, including cabinet 4, the circulating fan 1 being arranged on cabinet 4, air are high
It is closed cabinet to imitate filter 5 and cavity 7, the cabinet 4, and the circulating fan 1 is provided with air inlet 9 and air outlet 2, institute
State and baffle plate 3 is provided between air inlet 9 and air outlet 2, the cavity 7 is provided with interlayer, the Efficient air filtering with the bottom of cabinet 4
Device 5 is arranged on the side of cavity 7, and high-efficiency air filter 5 extends to the bottom of cavity 7, and the bottom of the opposite side of cavity 7 is provided with
Blower fan 8.
There are two stages in dry heat sterilization devices of the present utility model, the first stage opens circulating fan 1 and blower fan 8, by force
Whole air in dry heat sterilization devices processed reach after sterilizing requires by high-efficiency air filter 5, repeatedly circulation and enter second
Stage, heat sterilization.
Further, temp probe 6 is provided with the cavity 7, heater is provided between the cabinet 4 and cavity 7.It is logical
Heater is crossed to the air continuous heating in cavity 7, temp probe 6 is used to detect and control the air themperature in cavity 7.
In the first stage, if only open circulating fan 1, air by after high efficiency particulate air filter 5 enter cavity 7 in, and from
The side discharge of cavity 7, will cause the air of the side of cavity 7 is Laminar Flow, partial air be present and is not involved in circulating all the time, deposits
In the halfway hidden danger that sterilizes, and in detection, because the partial air is not involved in circulating, the partial air can not be detected.
Disturbance occurs in one denier air and forms part Turbulence Flow, the partial air can pollute other skies in follow-up sterilization process
Gas, cause sterilizing not thorough.Therefore, discharge air side in cavity 7 and be provided with blower fan 8, force all air to be joined in the first stage
With circulation, change Laminar Flow eliminates the halfway hidden danger of dry heat sterilization devices sterilizing into Turbulence Flow.
Further, the blower fan 8 is frequency conversion fan, and blower fan conversion frequency after a period of time is run can be further
Prevent the air of cavity side from, along fixed frequencies flow, forcing all air in cavity side to participate in circulation.
It is embodiment of the present utility model as described above.The utility model is not limited to above-mentioned embodiment, anyone
The structure change made under enlightenment of the present utility model should be learnt, it is every that there is same or like skill with the utility model
Art scheme, each falls within the scope of protection of the utility model.
