A kind of heated air circulation device of bakery
Technical field
The present invention relates to a kind of Bombyx bombycis bakery, the heated air circulation device of a kind of bakery, belong to agriculture
Product baking processing technique field.
Background technology
At present in south China silkworm district, the hot blast of existing bakery is i.e. got rid of after smoking cocoon outside barn, hot blast
Can not recycle, cause thermal waste, thus high cost.
Summary of the invention
Instant invention overcomes the defect that the hot blast of common bakery can not recycle, it is provided that a kind of bakery
Heated air circulation device, it is adaptable to south China each Bombyxmori Linnaeus district baking Bombyx bombycis.
For achieving the above object, the heated air circulation device of a kind of bakery of the present invention, including barn master
Body 1, warm-air pipe 2, flash vessel 3, recovery tube 4, combustor 5, combustion chamber the 6, first motor 7, capacity reducing
Device 8, rotary shaft 9, group flabellum the 10, second motor 11, moistureproof window 12, thermometer 13, it is characterised in that
Described warm-air pipe 2 is out rear from the bottom of described combustor 5 to be connected with described first motor 7, Jing Guokuo
Entering the inner expansion of barn main body 1 after container 3 is two, the warm-air pipe 2 outer wall in barn main body 1 and end
It is provided with air vent, it is therefore an objective to be beneficial to hot blast and distribute;In order to make heat distribute rapidly roasting cocoon, pacify in the middle part of barn
Equipped with a rotary shaft 9, its one end is connected with the second motor 11 outside barn main body 1, and axle has group fan
Leaf 10, after starting the second motor 11, rotary shaft rotates very fast, and hot blast is uniformly dispelled barn by flabellum
Both sides;Reclaim airduct 4 be two in room the outer wall of part have outside aperture, room and be divided into the hollow of sealing
Metal tube, installs along inwall in barn main body 1 internal upper part both sides and passes barn after capacity reducing device 8 is condensed to one
Outside main body 1, then being connected with the top of combustor 5, described moistureproof window 12 is installed in the both sides of barn main body 1
Top, totally four, two, every side, open during baking, it is therefore an objective to getting rid of dampness, described thermometer 13 is arranged on
Barn main body 1 is outside, it is therefore an objective to the temperature in monitoring barn.Described first motor 7 can also be installed in roasting
On recovery tube 4 between house-owner's body 1 and combustor 5.Described flash vessel 3 and capacity reducing device 8 are cuboid
Container, depending on the area in its six faces cross-sectional area according to warm-air pipe 2 or recovery tube 4, at least two
Face can accommodate two cross-sectional areas of warm-air pipe 2 or recovery tube 4, and remaining four face at least can accommodate warm-air pipe 2
Or a cross-sectional area of recovery tube 4.
The invention has the beneficial effects as follows, after using this device, can effectively the hot blast in combustor 5 be sent into
In bakery, recycle and reuse again after roasting cocoon, reach the purpose of saving heat energy, this device has system simultaneously
Make advantage easy, simple to operate.

Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
Embodiment one, warm-air pipe the 2, first motor 7, barn main body 1, recovery tube 4 and combustor 5 four
Between position and connected mode as shown in Figure 1;The recovery tube 4 position in barn main body 1 and connection side
Formula is as shown in Figure 3;Between combustor the 5, first motor 7, warm-air pipe 2, recovery tube 4, barn main body 1
External connection and thermometer 13 installation site as shown in Figure 4;The barn main body 1 of the present embodiment, combustion
The material burning room 5 is the rock cotton board with heat insulation function, and its thickness is 70 millimeters, warm-air pipe 2, recovery tube
The hollow stainless steel tube of a diameter of 200 millimeters of 4.The length of barn main body 1 be respectively 5 meters, 3.5
Rice, 2.4 meters, the length of combustor 5 is respectively 1 meter, 1 meter, 2.2 meters, smoke exhaust pipe 2, return
The shape of closed tube 4 can be circle can also be oval, it is also possible to be other shapes.
Comburant burns in combustion chamber 6, starts the first motor 7, and the hot blast of generation is bottom combustor 5
Enter in barn main body 1 after flowing to flash vessel 3 in warm-air pipe 2, at this moment start the second motor 11, rotary shaft
9 rotate, and hot blast is uniformly delivered to the four directions in barn main body 1, in the twitch of the first motor 7 by group flabellum 10
Under power, recovery tube 4 again the sirocco reclamation in barn main body 1, flow into combustor 5 after capacity reducing device 8
Top, flow to barn from warm-air pipe 2 again after being heated from top to bottom in combustor 5, so circulate profit
With hot blast, just reach the purpose of saving heat energy.
Embodiment two, the connected mode of recovery tube the 4, first motor 7 and combustor 5 is as shown in Figure 2.Example two
Be with example one difference, the first motor 7 be arranged on recovery tube 4, specifically, recovery tube 4 from
After the outer top of barn main body 1 bends, after being connected, the most upwards tap into the top of combustor 5 with the first motor 7
In portion, warm-air pipe 2 is then directly entered barn main body 1 from combustor 5, and remaining is identical with example one.
The effect of the two embodiment, is optimal with embodiment one, and identical at comburant, roasting cocoon amount is identical
In the case of, embodiment one needs 360 minutes, and embodiment two needs 400 minutes.
Recovery tube, the quantity of warm-air pipe also can make change more or less, barn main body, the volume of combustor
Making to make either large or small change, protection scope of the present invention is not limited to the present embodiment, every ability
Field technique personnel pass through claims of the present invention and the content of description, description, can derive well imagine,
Obvious change, still falls within protection scope of the present invention.
