Description

The cigarette heat separation device of a kind of barn combustion chamber

Technical field

The present invention relates to a kind of silk cocoon bakery, the cigarette heat separation device of especially a kind of barn combustion chamber, belongs to baking agricultural products processing technique field.

Background technology

At present in south China silkworm district, after the smoked cocoon of the hot blast of existing bakery, to barn outside, to get rid of, the structure of combustion chamber cannot separated fiery cigarette and heat, can not recycle hot blast, causes thermal waste, thus high cost.

Summary of the invention

The present invention has overcome the chamber of making a fire of common bakery cannot separated fiery cigarette and heat, the hot blast defect that can not recycle, and a kind of cigarette heat separation device of combustion chamber is provided, and is applicable to each silkworm district baking silk cocoon of south China.

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, burner hearth 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, recovery tube 4, motor 7 forms, and it is characterized in that, described burner hearth 11 main bodys are rectangular shape, and its four sides respectively label is A, B, C, D, napex is trapezoidal shape, described combustor outer casing 5 four sides surround cavity 12 with burner hearth 11 four sides, combustor outer casing 5 surrounds cavity 10 with burner hearth 11 tops, the ACD of cavity 10 dividing plate 14 welded seals for tri-limits, ventilations of leaving a blank of B face, described refractory brick 9 blocks pile up the surrounding of combustion chamber 6 and are close to the four sides inwall of

burner hearth

11, 8 minutes orthogonal being installed on refractory brick 9 of three layers of every adjacent two layers of described refractory metal pipe, its two-port is at the A of burner hearth 11, B, C, D four sides outer wall exposes with cavity 12 and communicates, described dividing plate 14 is welded between the burner hearth 11 four sides outer walls and combustion chamber 5 shells of refractory metal pipe 8 dew mouths, cavity 12 is divided into directed flow space 16, described warm-air pipe 2 one ends are received 12 li of described cavitys, from combustor outer casing 5, stretch out through motor 7 and put in again barn main body 1, described smoke exhaust pipe 3 is immediately on burner hearth 11 tops, pass after combustor outer casing 5 and be bent downwardly and tap into 1 li of barn main body, described recovery tube 4 out taps into afterwards in combustor outer casing 5 tops from barn main body 1, its port is communicated with cavity 10, described stove sieve 15 is installed in combustion chamber 6 bottoms, described ashcan case 13 is installed in stove and sieves 15 lower bottom parts.

Refractory metal pipe 8 can be quantitatively more than 21, can divide three layers to lay above, between every two, has spacing, can not be adjacent to by putting, otherwise the fiery cigarette of 6 li of combustion chambers just cannot pass, and the height that described refractory brick 9 is piled up is more than 100 centimetres.It is dirty along B face that warm braw in barn main body 1 enters cavity 10 through recovery tube 4, along the outer wall of burner hearth 11, press the refractory metal inside pipe wall → D of the directed flow space 16→ lower floor face of directed flow space 16 → B face of 16→ middle level, directed flow space refractory metal pipe 8 inwalls → A face of directed flow space 16 → C face of B face → upper strata refractory metal pipe 8 inwalls → D face, according to such direction order three, enter three and at D face, along cavity 12, flow to warm-air pipe 2 after going out three layers of refractory metal pipe 8, refractory metal pipe 8 produces heat after being burnt, force by the warm braw temperature in it and raise and become hot blast under the effect of the twitch force of motor 7, by warm-air pipe 2, enter 1 li of roasting cocoon of barn main body again.The outer wall spacing that the fiery cigarette that combustion chamber 6 produces is upward through every two of three layers of refractory metal pipe 8 enters smoke exhaust pipe 3, and fiery cigarette can not penetrate in the inwall pipeline of refractory metal pipe 8, has so just reached the fiery cigarette object separated with heat.

The invention has the beneficial effects as follows, use after this device, fire cigarette and the uncommon passage of hot blast, the fiery cigarette that combustion chamber is 11 li is separated with hot blast, hot blast is sent recycle and reuse again after 1 li of roasting cocoon of barn main body to, reach saving heat energy, cost-saving object, simultaneously this device have advantages of make easy, simple to operate.

The specific embodiment

In Fig. 1-Fig. 5, the title that label is corresponding: 1-barn main body, 2-warm-air pipe, 3-smoke exhaust pipe, 4-recovery tube, 5-combustor outer casing, 6-combustion chamber, 7-motor, 8-refractory metal pipe, 9-refractory brick, the cavity that 10-combustor outer casing 5 and burner hearth 11 tops surround, 11-burner hearth, the cavity that 12-shell 5 and burner hearth 11 outer walls surround, 13-ashcan case, 14-dividing plate, 15-stove sieve, 16-directed flow space.

Below in conjunction with accompanying drawing, the invention will be further described.Position between warm-air pipe 2, recovery tube 4, smoke exhaust pipe 3, barn main body 1 and combustor outer casing 5 and connected mode are as shown in Figure 1 and Figure 2; The position relationship in tetra-face structures of burner hearth 11 outer wall ABCD, dividing plate 14, directed flow space 16 is as shown in Fig. 3-1,3-2,3-3, the welding method in directed flow space 16 is, in four faces in the cavity 12 of burner hearth 11 outer walls that expose at refractory metal pipe 8, there is one side to leave a blank, make gas channel, dividing plate 14 welded seals for its excess-three face, i.e. so-called directed flow space; As shown in Figure 4, the B limit at burner hearth 11 tops is welding diaphragm 14 not, leaves a blank for burner hearth 11 tops, dividing plate 14, combustor outer casing 5 connected modes and the cavity 10 surrounding, cavity 12; As shown in Figure 5, building refractory brick object is to prevent that the inwall of burner hearth 11 is by scorification for the combustion chamber 6 of burner hearth 11 inside, refractory brick 9, refractory metal pipe 8, stove sieve 15, ashcan case 13 position annexations.The barn main body 1 of the present embodiment, the material of combustor outer casing 5 are the rock cotton board with heat insulation function, and its thickness is 70 millimeters, and the diameter of warm-air pipe 2, recovery tube 4 is the hollow stainless steel tube of 200 millimeters, and the material of refractory metal pipe 8 is stainless steel tubes.The length of barn main body 1 is respectively 5 meters, 3.5 meters, 2.4 meters, and the length of combustion chamber 5 is respectively 1 meter, 1 meter, 2.2 meters, and the shape of smoke exhaust pipe 2, recovery tube 4 can be that circle can be also oval, can also be other shapes.

A feature of the present invention is exactly that fiery cigarette and hot blast do not flow in same passage, comburant is in 6 li of burnings of combustion chamber, starter motor 7,2 li of the hot blast warm-air pipes that produce enter in barn main body 1, under the twitch force of motor 7, thereby recovery tube 4 enters refractory metal pipe 8 inwalls the warm braw recovery flows into combustion chamber enclosure 5 in barn main body 1 again and is heated, and down flows to afterwards 2 li of warm-air pipes again; And the fiery cigarette that comburant produces up enters into smoke exhaust pipe 3 through between refractory metal pipe 8 outer walls from combustion chamber 6 again, so just reached the fiery cigarette object separated with hot blast in combustion chamber.Too much when burning, the ash that burning produces just falls and enters ashcan case 13 from stove sieve 15, when ashcan case is full, can pulls out and outwell.

The quantity of refractory metal pipe, refractory brick also can be done variation more or less; the volume of barn main body, combustion chamber is yet done to do either large or small variation; protection scope of the present invention is not only confined to the present embodiment; every those skilled in the art are by content and the description thereof of the claims in the present invention book and description; can derive well imagine, apparent variation, still belong to protection scope of the present invention.
