A kind of smoke and heat separation device for combustor of curing barn
Technical field
The present invention relates to a kind of silk cocoon bakery, especially a kind of smoke and heat separation device for combustor of curing barn, belong to agricultural production
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, the structure of combustion chamber
Make and cannot separate fire cigarette and heat, it is impossible to recycle hot blast, cause thermal waste, thus high cost.
Summary of the invention
The room of making a fire that instant invention overcomes common bakery cannot separate fire cigarette and lacking that heat, hot blast can not recycle
Fall into, it is provided that the cigarette heat separation device of a kind of combustion chamber, it is adaptable to south China each silkworm district baking silk cocoon.
For achieving the above object, the cigarette heat separation device of a kind of combustion chamber of the present invention, by combustor outer casing 5, stove
Thorax 11, combustion chamber 6, stove sieve 15, ashcan case 13, refractory brick 9, refractory metal pipe 8, dividing plate 14, smoke exhaust pipe 3, warm-air pipe 2, return
Closed tube 4, motor 7 form, and it is characterized in that, described burner hearth 11 main body is rectangular shape, and its four sides is numbered A, B, C, D respectively,
The trapezoidal shape in top, described combustor outer casing 5 four sides surrounds the second cavity 12 with the four sides of the rectangular shape part of burner hearth 11,
Combustor outer casing 5 surrounds the first cavity 10 with the trapezoidal shape part at burner hearth 11 top, the bottom of the trapezoidal shape part of burner hearth 11
Having spacing between ABCD four sides and combustor outer casing 5, wherein ACD tri-dividing plate 14 welded seal, B leaves a blank in face ventilations, beneficially
Gas is from the B surface current of the first cavity 10.Described refractory brick 9 is built in piling up the surrounding of combustion chamber 6 and being close to the four sides of burner hearth 11
Wall, 8 points of three layers of every adjacent two layers of described refractory metal pipe are orthogonal to be installed on refractory brick 9, and its two-port is at burner hearth 11
A, B, C, D four sides outer wall expose and communicate with the second cavity 12, described dividing plate 14 is welded on refractory metal pipe 8 and reveals the burner hearth of mouth
Between 11 four sides outer walls and combustion chamber 5 shell, the second cavity 12 being divided into directed flow space 16, described warm-air pipe 2 one terminates
In described second cavity 12, extending out past motor 7 from combustor outer casing 5 and put in barn main body 1 again, described smoke exhaust pipe 3 is tight
Being connected on burner hearth 11 top, be bent downwardly and tap in barn main body 1 after passing combustor outer casing 5, described recovery tube 4 is from barn main body
Tapping in combustor outer casing 5 top in 1 the most afterwards, its port and the first cavity 10 connect, and described stove sieve 15 is installed in combustion chamber 6
Bottom, described ashcan case 13 is installed in stove and sieves 15 lower bottom parts.
Refractory metal pipe 8 can be quantitatively more than 21, and more than three layers can be divided to lay, between having between every two
Away from, it is impossible to being adjacent to by putting, otherwise the fiery cigarette in combustion chamber 6 just cannot pass, and the height that described refractory brick 9 is piled up is 100 centimetres
Above.When the warm braw in barn main body 1, to enter the first cavity 10 through recovery tube 4 dirty along B face, and the outer wall along burner hearth 11 is pressed
16 → the middle level, directed flow space in 16 → C face, directed flow space in B face → upper strata refractory metal pipe 8 inwalls → D face is resistance to
In directed flow space 16 → lower floor refractory metal pipe in 16 → B face, directed flow space in high-temperature metal pipe 8 inwalls → A face
Wall → D face, according to such direction order three enter three go out three layers of refractory metal pipe 8 after flow to heat in D face along the second cavity 12
Airduct 2, refractory metal pipe 8 produces heat after being burnt, and is forced through its interior warm braw temperature rising and becomes hot blast at motor 7
Twitch power effect under, then entered the inner roasting cocoon of barn main body 1 by warm-air pipe 2.The fiery cigarette that combustion chamber 6 produces is upward through three layers
The outer wall spacing of every two of refractory metal pipe 8 enters smoke exhaust pipe 3, and fire cigarette will not penetrate into the inner wall tube of refractory metal pipe 8
In road, thus reach the purpose that fiery cigarette separates with heat.
The invention has the beneficial effects as follows, after using this device, fire cigarette and the most common passage of hot blast, the fire in combustion chamber 11
Cigarette separates with hot blast, and hot blast is sent into recycle and reuse again after the inner roasting cocoon of barn main body 1, reaches saving heat energy, cost-effective
Purpose, this device has the advantage that making is easy, simple to operate simultaneously.

Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.Warm-air pipe 2, recovery tube 4, smoke exhaust pipe 3, barn main body 1
And position between combustor outer casing 5 and connected mode are as shown in Figure 1 and Figure 2;Burner hearth 11 outer wall ABCD tetra-face structures, dividing plates
14, the position relationship in directed flow space 16 is as shown in Fig. 3-1,3-2,3-3, and the welding method in directed flow space 16 is,
Four faces in second cavity 12 of burner hearth 11 outer wall that refractory metal pipe 8 exposes there is one side leave a blank, make gas channel, its
Excess-three face dividing plate 14 welded seal, the most so-called directed flow space;Burner hearth 11 top, dividing plate 14, combustor outer casing 5 connect
Mode and first cavity the 10, second cavity 12 of surrounding as shown in Figure 4, not welding diaphragm 14, B limit at burner hearth 11 top, leave a blank;
Combustion chamber 6 within burner hearth 11, refractory brick 9, refractory metal pipe 8, stove sieve 15, ashcan case 13 position annexation such as Fig. 5 institute
Showing, building refractory brick purpose is that the inwall preventing burner hearth 11 is by scorification.The barn main body 1 of the present embodiment, the material of combustor outer casing 5
For having the rock cotton board of heat insulation function, its thickness is 70 millimeters, warm-air pipe 2, a diameter of 200 millimeters of recovery tube 4 hollow not
Rust steel pipe, the material of refractory metal pipe 8 is stainless steel tube.The length of barn main body 1 be respectively 5 meters, 3.5 meters, 2.4
Rice, the length of combustion chamber 5 is respectively 1 meter, 1 meter, 2.2 meters, and smoke exhaust pipe 2, the shape of recovery tube 4 can be that circle can also
It is oval, it is also possible to be other shapes.
A feature of the present invention is exactly that fire cigarette does not flows with hot blast in same passage, and comburant fires in combustion chamber 6
Burn, start motor 7, in the hot blast warm-air pipe 2 inner entrance barn main body 1 of generation, under the twitch power of motor 7, recovery tube 4 again
Warm braw in barn main body 1 reclaims flows into combustion chamber enclosure 5 and is heated, the most down hence into refractory metal pipe 8 inwall
Flow in warm-air pipe 2;And the fiery cigarette that comburant produces, then up enter again through refractory metal pipe 8 outer wall from combustion chamber 6
Enter in smoke exhaust pipe 3, thus reached the purpose that the fiery cigarette in combustion chamber separates with hot blast.When burned many, burning produces
Ash just 15 fall through into ashcan case 13 from stove sieve, ashcan case can pull out time full and outwell.
Refractory metal pipe, the quantity of refractory brick also can make change more or less, barn main body, combustion chamber volume also
Also making to make either large or small change, protection scope of the present invention is not limited to the present embodiment, and every those skilled in the art are led to
Cross claims of the present invention and the content of specification and description thereof, can derive and well imagine, obviously change, still belong to
In protection scope of the present invention.
