In figure, 1 is upper bellows main casing, and 2 be flange, and 3 be communicating pipe, and 4 be mixing chamber.
Specific embodiment
In order to make those skilled in the art better understand the scheme of the utility model, with reference to the accompanying drawing and embodiment
The utility model is described in further detail.
Referring to Fig. 1, Fig. 2, it is provided by the utility model can allow air and return the well-mixed burner upper bellows of cigarette, packet
Include hollow upper bellows main casing 1；
The bottom of the upper bellows main casing 1 has ventilation opening, is equipped with flange 2 at the ventilation opening；
The ventilation opening of 1 bottom of upper bellows main casing by flange and hollow air box (i.e. lower bellows, in
Ventilation blower is installed) at the top of air outlet be connected, therefore, by the utility model, can easily disassemble and install windward
Case main casing 1 makes full use of the environment at scene；
The inner space volume of the upper bellows main casing 1, the air box being connected greater than its bottom (i.e. lower bellows)
Inner space volume.
In the present invention, the air inlet of the air box is connected with the air outlet of a burner.
It should be noted that the air inlet of pressure fan or the burner can be equipped on burner for burner
Mouth is connected with air supply duct, it is, of course, also possible to be other aeration structures, so as to suck for combustion-supporting outside air
It can by air box (can be the shape of the user presets such as rectangle or cylinder) for the utility model
The flue gas (returning cigarette) that air and burning to burner sucking generate carries out first time mixing；Then, upper bellows are continued through,
To the air after air box mixed once and cigarette can be returned, carry out being sufficiently mixed again, to guarantee air and return cigarette
Mixed effect so that the gas that is formed after mixing, is again introduced into burner, recycling is burnt again, can effectively inhibit nitrogen
The generation of the pollutants such as oxide has good energy conservation and environmental protection double effects.
On the utility model, specific implementation, the upper bellows main casing 1 includes hollow communicating pipe 3 and hollow mixed
Close cavity 4；
The communicating pipe 3 is connected with mixing chamber 4；
Connection between 4 inner wall of top surrounding and the mixing chamber of 3 inner wall of communicating pipe is to be smoothly connected.
In specific implementation, the shape of the mixing chamber 4 is the cylinder of genesis analysis, the radial direction of the mixing chamber 4
Inner wall is arc-shaped inner wall.
In specific implementation, the top left side of 3 inner wall of communicating pipe, is tangent between the inner wall of the mixing chamber 4
Connection.
In specific implementation, therefore the transverse width of the mixing chamber 4, the transverse width greater than the communicating pipe 3 has
Conducive to providing sufficient air and going back to the space of cigarette mixing, guarantees that mixing is full and uniform, there is good mixed effect.
In specific implementation, the central point of the mixing chamber 4, positioned at the right of the vertical center line of the communicating pipe 3, no
On same straight line, therefore, is conducive to external air and returns cigarette after the entrance of the ventilation opening of 1 bottom of upper bellows main casing,
Can be formed in mixing chamber 4 rotation, along mixing chamber arc-shaped inner wall flow reflux airflow so that air and
Returning cigarette mixing can be sufficiently mixed, and be further ensured that mixed effect, so that subsequent burning is more abundant, be more advantageous to energy-saving ring
It protects.
On the utility model, specific implementation, the size of the upper bellows main casing 1 is the size increased, specifically can be with
Are as follows: the size of upper bellows main casing 1, the size of the air box being connected greater than its bottom (i.e. lower bellows) or upper bellows master
The inner space volume of shell 1, the inner space volume of the air box being connected greater than its bottom (i.e. lower bellows).Therefore, energy
Enough so that the flue gas that the air and burning that are flowed by air box generate, can have bigger blending space, so that guarantee is mixed
Close it is full and uniform, have good mixed effect.Finally make the gas formed after mixing, is again introduced into burner, then follow
Ring burns again, can effectively inhibit the generation of the pollutants such as nitrogen oxides, has good energy conservation and environmental protection double effects.
Based on above technical scheme it is found that practical, the energy-saving and environmental protection of the utility model, can effectively improve fuel
Etc. resources utilization rate, to improve the burner competitiveness of product in market.
In conclusion compared with prior art, it is provided by the utility model that air and time cigarette can be allowed well-mixed
The flue gas (returning cigarette) that the air that outer fan sucks is formed with burner combustion can be sufficiently mixed by burner upper bellows
Afterwards, it enters back into burner to burn, so that burning is more abundant, therefore, can effectively inhibit the pollutants such as nitrogen oxides
It generates, there is good environment protecting, be of great practical significance.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
