It with knob 5.2 is threadedly engaged set on 1 outside of shell and by external screw thread；4 upper end of bracket is arranged or hook is located in shaft 5.1 and with
Shaft 5.1 is flexibly connected, i.e. the settable hook portion in 4 upper end of bracket or ring portion 7, if hook portion then its be hooked in shaft 5.1, and if
Ring portion 7 is then sheathed in shaft 5.1 (on condition that first backing out the knob 5.2 in shaft 5.1) from 5.1 outer end of shaft.When bracket 4
After upper end is set in shaft 5.1, knob 5.2 is twisted in shaft 5.1 and tightening, so that 4 upper end of bracket is screwed 5.2 and is clamped in
1 outer wall of shell, and before bracket 4 is fixedly clamped, its angle can be adjusted by runing rest 4, to change 4 bearing height of bracket
Then heating device height is influenced, so that heating device can be adapted for the demand of different volumes culture bag 8.In shaft 5.1 also
Washer (not shown) can be arranged.By the effect of washer, knob 5.2 may make more to fasten the fixation of bracket 4.
The bearing surface in left shell portion 1.1 and right shell body portion 1.2 is equipped with the fastener 9 mutually fastened, and fastener 9 may include one
The box and pin of fixed number amount is respectively arranged on left shell portion 1.1 and right shell body portion 1.2.By the effect of fastener 9, make left shell portion
1.1 and right shell body portion 1.2 can quickly split and splice merging, use is more convenient, and structure is simple, at low cost.Relative to background
The structure for the filter heater mentioned in technology is simpler.
1 inner wall of shell there are two heating sheet 2 is preferably at least, set on corresponding 3.1 position of pneumatic filter.Heating sheet 2
It can be silica-gel electrothermic silk heating sheet 2.Bracket 4 is flexible metallic support 4, and outer wall packet is equipped with plastic layer or rubber layer, is led to
It crosses plastic layer or rubber layer can increase stiction between bracket 4 and disposable flexibly foster bag 8, effectively prevent sliding relatively
It is dynamic.Bracket 4 is flexible but not to be soft, with certain hardness, can at least support entire heating device and indeformable
Or deformation quantity is smaller.1 side wall of shell can be equipped with the electric wire opening passed through for power supply line 6, quantity and add that specific electric wire is open
2 quantity of backing is corresponding, i.e., each corresponding electric wire opening of heating sheet 2.
In use, heating device is coated on outside the included gas filter system 3 in disposable 8 upper surface of flexibly foster bag
Portion；That is, separation left shell portion 1.1 and right shell body portion 1.2, by the pneumatic filter 3.1 of gas filter system 3, air inlet pipe 3.2,
Escape pipe 3.3 and gas stop valve 3.4 are all placed between left shell portion 1.1 and right shell body portion 1.2, then remerge left shell portion
1.1 with right shell body portion 1.2, and it is fixed by fastener 9.And it is directed to different disposable flexibly foster bags 8, by unscrewing knob
5.2, so that bracket 4 5.1 can turn an angle around the shaft, so as to adjust 4 height of bracket, tightened again after being adjusted to proper height
Knob 5.2 can fix bracket 4.After connecting external power supply, heating sheet 2 is powered to totally-enclosed to carrying out inside entire shell 1
Formula heating, entire gas filter system 3 are heated.
Fluid temperature in disposable flexibly foster bag 8 is 37 ± 0.2 DEG C, and gas temperature is 30 ± 5 DEG C in bag, gas in bag
Body relative humidity is 80 ± 5%RH, under certain pressure effect, by the gas with certain temperature and humidity through gas filtration system
Unite outside 3 output bags, if bag external environment temperature is lower and bag in gas output speed it is relatively slow in the case where, gas can be caused in gas mistake
Condensation, the condensed water condensed in pneumatic filter 3.1 can directly block the filter membrane of pneumatic filter 3.1 in filter system 3, go out
The condensed water condensed in tracheae 3.3 and gas stop valve 3.4 will flow back and deposit inside pneumatic filter 3.1, block gas
3.1 filter membrane of filter, can not work normally pneumatic filter 3.1, and the condensed water condensed in air inlet pipe 3.2 will form air film
Block bottom caliber.Therefore the heating device of the utility model reduces gas by the way of integral coating gas filter system 3
The difference of gas temperature inside and outside body filtration system 3 makes gas that can not occur condensing phenomenon in entire gas filter system 3.
In order to disclose the actual effect of utility model, under the same conditions to three kinds of different heatings as shown in Figure 1, 2, 3
Structure type compares experiment, is open heating, semi-enclosed heating and totally enclosed type heating respectively.Low velocity gas stream
Speed is set as 50ml/min, and gas relative humidity is 80 ± 5%RH.T1 is operating ambient temperature, and T2 is 3.1 table of pneumatic filter
Face temperature, T3 are gas temperature in culture bag 8, and T4 is gas temperature in gas stop valve 3.4, and each testing time is 1 small
When, every kind of test is repeated 5 times, and is then averaged.Test result is as follows:
Test result is shown, firstly, gas temperature and work in working environment in 25 DEG C or more and gas filter system 3
When making environment temperature difference less than 4 DEG C, i.e. when temperature gap between T4 and T1 is less than 4 DEG C, three kinds of heating methods can be prevented
Only condensed water occurs inside gas filter system 3；Secondly, open and two kinds semi-enclosed, gas filtration system
When gas temperature and operating ambient temperature in system 3 differ 4 DEG C or more, i.e. temperature gap between T4 and T1 is greater than 4 DEG C or more
When, it may appear that condensed water, and with the reduction of operating ambient temperature, condensed water phenomenon is more obvious；And in totally enclosed type,
Even if that is, in the lower situation of T1 temperature, the gas temperature difference is less than 1 inside and outside gas filter system 3 under lower working environment problem
DEG C, i.e. when temperature gap between T4 and T2 is less than 1 DEG C, also evaporated condensation water occurs, and shows totally enclosed type heating structure not by outer
Boundary's temperature influences, and can still guarantee that pneumatic filter 3.1 continues to work normally under low temperature low speed environments.From experimental result also into
One step proves that the heating device using totally enclosed type heating structure of the utility model can effectively avoid low temperature low velocity gas in gas
The phenomenon that condensed water is generated in body filtration system 3.
