Specific embodiment:
With reference to the accompanying drawing, detailed description of the present invention specific embodiment.
As depicted in figs. 1 and 2, cooling centrifugal hot air circulation blower, including motor 1 and electricity can be carried out to stove inside
Arbor 2, which is characterized in that on the motor shaft 2 rotation be socketed with centrifugal impeller 4 after a preceding centrifugal impeller 3 and one, after from
Lobus cardiacus wheel 4 is socketed with one piece on the motor shaft 2 between rear centrifugal impeller 4 and motor 1 between preceding centrifugal impeller 3 and motor 1
The air inlet 6 of connecting plate 5, the preceding centrifugal impeller 3 is located remotely from the side of motor 1, and the air inlet 6 of rear centrifugal impeller 4 is located at
Towards the side of connecting plate 5, several air holes corresponding with the air inlet 6 of rear centrifugal impeller 4 are offered on the connecting plate 5
7, connecting plate 5 is located at 1 side of motor and is connected with the cover board 8 that can close air holes 7.
By the way that preceding centrifugal impeller 3 and rear centrifugal impeller 4 are arranged on motor shaft 2, by 6 court of air inlet of rear centrifugal impeller 4
Connecting plate 5 opens up, while air holes 7 is arranged on connecting plate 5 and can close the cover board 8 of air holes 7, in this way, needing in stove
When portion is cooled down, openable air holes 7 sucks cold wind outside stove in stove by rear centrifugal impeller 4 by air holes 7
Portion carries out heat exchange to reduce stove internal temperature, using centrifugal hot wind of the present invention with stove internal high temperature gas
After circulating fan, installation cooling blower can not be had on stove, this greatly reduces the production cost and maintenance cost of stove.
The preceding centrifugal impeller 3 and rear centrifugal impeller 4 mutually amplexiform, end plate 9 of the preceding centrifugal impeller 3 towards 1 side of motor
End plate 9 with rear centrifugal impeller 4 far from 1 side of motor is same end plate 9, centrifugal impeller 3 and rear centrifugation before alleviating in this way
The total weight of impeller 4 reduces the load of motor 1, saves electric energy, while improving the rotation of preceding centrifugal impeller 3 and rear centrifugal impeller
Stability.
The cover board 8 circularizes, and the air holes 7 is evenly arranged on around motor shaft 2 at fan-shaped and axial direction, adjacent two air holes 7
Between angle be greater than the angles of 7 liang of straight flanges of air holes, offer on the cover board 8 with the one-to-one fan-shaped pylone 16 of air holes 7,
Rotating plate 8 moves the position of through-hole 16, so that through-hole 16 is staggered with 7 face of air holes or part face or completely, to open
Air holes 7 adjusts the opening size of air holes 7 or closes air holes 7, and it is convenient to operate, and can adjust the air inlet of cold wind according to actual needs
Amount.
The side side that the connecting plate 5 is centrifuged motor 4 after is connected with the incubator being socketed on motor shaft 2
Body 10, thermal-insulating body 10 is interior to be filled with thermal insulation material 11, side and rear centrifugal impeller 4 phase of the thermal-insulating body 10 back to connecting plate 5
Right, thermal-insulating body 10 is towards offering cold wind import corresponding with the air inlet 6 of rear centrifugal impeller 4 on the face of rear centrifugal impeller 4
12, the thermal insulation material 11 is internally provided with the cold air duct 13 of connection cold wind import 12 and each air holes 7.
Stove internal high temperature can be isolated in thermal-insulating body 10, and motor 1 is avoided to meet high temperature damage.
The cold wind import 12 is slightly less than the air inlet 6 of rear centrifugal impeller 4, is connected in cold wind import 12 and is centrifuged leaf backward
The conduit 14 that the air inlet 6 of wheel 4 extends, the air inlet 6 of centrifugal impeller 4 after conduit 14 is inserted into, so that rear centrifugal impeller 4 be made to rotate
When, the negative pressure that air inlet 6 generates guides external cold wind to enter rear centrifugal impeller 4 in conduit 14.
There are gaps 15 between the conduit 14 and the air inlet 6 of rear centrifugal impeller 4, when cover board 8 closes air holes 7
It waits, hot wind can enter rear centrifugal impeller 4 by gap 15 inside stove, carry out hot air circulation.
The course of work of the present invention is: as shown in Figure 1 and Figure 2, centrifugal hot air circulation blower of the present invention passes through connecting plate
5 are mounted on furnace wall 17, and motor 1 is located on the outside of stove, and when stove internal temperature is in normal range (NR), cover board 8 closes institute
There are air holes 7, the rotation of 1 drive motor shaft 2 of motor, motor shaft 2 drives preceding centrifugal blower 3 and rear centrifugal blower 4 to rotate, preceding centrifugation wind
Machine 3 and rear centrifugal blower 4 suck hot wind from respective air inlet 6, are discharged from the air outlet of side, make hot wind shape inside stove
At circulation, wherein hot wind enters rear centrifugal blower 4 from the gap 15 between the air inlet 6 and conduit 14 of rear centrifugal blower 4.
When stove internal temperature is excessively high, rotating plate 8 keeps the through-hole 16 on cover board 8 opposite with 7 part of air holes or complete
Face, this is, negative pressure is formed at Shi Qi air inlet 6 since rear centrifugal blower 4 rotates, and centrifugal blower after the insertion of conduit 14
In 4 air inlet 6, therefore, conduit 14 directly sucks cold wind outside stove from air holes 7, cold wind through cold air duct 13, cold wind into
Mouth, conduit 14 are directly entered in rear centrifugal blower 4, the air outlet of 4 inner passage of centrifugal blower, 4 side of centrifugal blower after after
It is discharged to inside stove, with the high-temperature gas heat exchange inside stove, reduces stove internal temperature.
After stove internal temperature is reduced to normal range (NR), rotating plate 8 closes air holes 7 again, and rear centrifugal blower 4 restores
Hot wind circulation function.
The principles and effects of the invention, and the embodiment that part uses only is illustrated in above-described embodiment,
And is not intended to limit the present invention；It should be pointed out that for those of ordinary skill in the art, not departing from the invention structure
Under the premise of think of, various modifications and improvements can be made, and these are all within the scope of protection of the present invention.
