Description

Baking box room

Technical field

The utility model relates to roasting plant manufacturing technology field, especially a kind of baking box room of using for toasting plank sheet material, food, medicinal material and sheet metal baking vanish.

Background technology

In traditional built-in bakery, the smoke pipeline of combustion chamber is directly discharged flue gas in the atmosphere outside combustion chamber, when discharging useless flue gas, also the heat of quite a few is discharged, and the consequence causing is like this: the thermal efficiency is low, and cost is high.

Summary of the invention

The purpose of this utility model is to provide a kind of baking box room, it can solve when baking the thermal efficiency low, the problem that cost is high.

In order to address the above problem, the technical solution adopted in the utility model is: this baking box room, comprise baking vessel, combustion chamber, in described combustion chamber, be outside equipped with heat collecting chamber, the top of described combustion chamber is communicated with hot channel, and described hot channel is putting near a side of described baking vessel in described baking vessel and is being communicated with chimney after being located at the aspiration box on described baking vessel top; Described aspiration box is provided with through hole; Described aspiration box is provided with gas outlet, and this gas outlet is communicated with described heat collecting chamber by upper return air duct; The bottom of described heat collecting chamber is communicated with the lower air-blowing box that is arranged on described baking vessel bottom by lower gas-distributing pipe road; Described lower air-blowing box is provided with air vent; On the circulation canal forming between described heat collecting chamber and described baking vessel, in the connecting pipe outside described heat collecting chamber and described baking vessel, be provided with circulating fan.

In technique scheme, more specifically scheme can also be: described hot channel at least a section in described baking vessel is made for metal material.

Further: described hot channel at least a section in described baking vessel is made for nonmetallic materials that can heat conduction.

Further: the baking box room according to described in

claim

1 or 2 or 3, is characterized in that: between described heat collecting chamber and described baking vessel, be provided with the return gas channel that is communicated with both, described hot channel stretches in described baking vessel from this return gas channel; Between described hot channel and described return gas channel inwall, be provided with gap.

Further: the size of the exhaust vent of described lower air-blowing box is to regulate.

Further: below the described hot channel in described baking vessel, to be provided with thermal insulation board.

Owing to having adopted technique scheme, compared with prior art, the beneficial effect having is the utility model:

1, the flue gas that the utility model produces in combustion chamber is first through the hot channel around aspiration box one circle, then just from chimney, discharge, in this process, the heat of flue gas is easy to import in baking vessel, the heat of this part also can be inhaled in aspiration box and add in thermal cycle, original heat of directly discharging flue gas is partly directly used in to baking timber etc., thereby has improved the thermal efficiency.

2, hot channel of the present utility model replaces the smoke pipeline of prior art and makes with the good materials such as metal of heat conduction, because it is under the brushing of circulated air, so the heat that it gives out is taken away by wind soon, gathering of hot channel heat that return gas channel also reduces is set in addition, the number of times so also easily being damaged by roasting the wearing of hot gas with regard to reducing hot channel, extend the cycle of changing hot channel, thereby reduce production costs, enhance productivity.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Embodiment 1:

Baking box room shown in Fig. 1 and Fig. 2, comprise baking vessel 4, combustion chamber 2, in combustion chamber, 2 are outside equipped with heat collecting chamber 1, the top of combustion chamber 2 is provided with hot channel 3, between heat collecting chamber 1 and baking vessel 4, is provided with return gas channel 5, and hot channel 3 stretches into baking vessel 4 tops from the side wall upper part of heat collecting chamber 1 by return gas channel 5, and around aspiration box 6 one circles that are located at baking vessel 4 tops, be then connected with the chimney 7 that is located at baking vessel 4 tops; Between hot channel 3 and return gas channel 5 inwalls, be provided with gap, avoid hot channel 3 to give out heat and damage return gas channel 5 inwalls; Below hot channel 3 in baking vessel, be provided with thermal insulation board 13; Thermal insulation board 13 plays the directly radiation to baking vessel's 4 domestic demand roasted material of barrier hot channel 3 heat radiations, in order to avoid cause the hot-spot of roasted material; The top of aspiration box 6 is provided with gas outlet 8, and this gas outlet 8 is connected with one end of upper return air duct 9, and the other end of upper return air duct 9 is connected with the top of heat collecting chamber 1; The bottom of heat collecting chamber 1 is communicated with the one end in lower gas-distributing pipe road 12, and the other end in lower gas-distributing pipe road 12 is communicated with the lower air-blowing box 10 that is located at baking vessel 4 bottoms; In the circulation canal of heat collecting chamber 1, lower gas-distributing pipe road 12 and

baking vessel

4 and 9 formation of upper return air duct, be provided with circulating fan 11; In the present embodiment, circulating fan 11 is arranged on lower gas-distributing pipe road 12, and at other embodiment, circulating fan 11 also can be arranged on return air duct 9; Four sides in aspiration box 6 have a plurality of air admission holes; The exhaust vent that has a plurality of adjustable sizes in four sides of lower air-blowing box 10, its adjusting is inserted cover plate by activity and is realized.

When work, need the material of baking to be placed in baking vessel 4, fuel is put combustion chamber 2 burnings into, and the flue gas producing after burning is discharged from hot channel 3, as shown in the arrow in Fig. 1 hot channel 3; Flue gas is discharged from chimney 7 after enclosing around aspiration box 6 one along hot channel 3, and hot channel 3 is the heats that utilize as much as possible burning to produce around the effect of aspiration box 6, improves the thermal efficiency; Fuel after the burning of 2 li of combustion chambers, due to the effect of heat, the hot-air that heat collecting chamber 1 savings is a large amount of, circulating fan 11 is extracted into the hot-air of this part in lower air-blowing box 10, then from the exhaust vent of lower air-blowing box 10, enters that baking vessel 4 is interior toasts material.As shown in the arrow in Fig. 1 circulating line; Under the effect of circulating fan 11, hot gas circulates by following path: heat collecting chamber 1 → lower gas-distributing pipe road 12 → lower air-blowing box, 10 → baking vessel 4 → aspiration box 6 → upper return air duct 9 → heat collecting chamber 1; With this simultaneously, because hot channel 3 is metal, so the heat of flue gas is therein easy to import in baking vessel 4, the heat of this part also can be inhaled in aspiration box 6 and add in thermal cycle, thereby has improved the thermal efficiency.

In the present embodiment, hot channel 3 use metals are made, and because it is always under the brushing of circulated air, so the heat that it gives out is taken away by wind soon, it is just not easy to be worn by hot gas is roasting like this; The effect that return gas channel 5 is set is also for this object; Owing to need not often changing hot channel 3, add the thermal efficiency and improved, so cost has just declined.

Embodiment 2: hot channel 3 use heat conduction porcelain pipes are made, and other operation principle is identical with embodiment 1.
