The mixing tubes 26 form at least a part of the protective cover 16, for example, all the mixing tubes 26 form a bottom protective cover unit of the protective cover 16, the inner side of the mixing tubes 26 facing the flame chamber 22 is opened with flame holes, and the flame holes form an outlet 20b for outputting mixed gas.

In other words, the mixing tube 26 is not only part of the shroud 16, but is also a mixing carrier for the venturi burner 20. This kind of design is integrated to a side's siphunculus with the shrink mixing section and the diffusion mixing section of traditional venturi combustor in, has reduced and has arranged the space requirement, saves a wall section of thick bamboo, can enlarge the size of protection casing moreover, enlarges the flame district, increases torch combustion space, has reduced the inside heat intensity that holds in flame district, can effectively reduce flame length, burning noise. The mixing pipe 26 is a rectangular pipe having a rectangular parallelepiped structure, and inner plates 50 are provided on at least two inner side walls of the mixing pipe 26 opposite to each other on the side of the air inlet portion 20 a. In the illustrated embodiment, the inner plates 50 are provided on the four inner side walls of the mixing pipe 26 on the side of the intake portion 20 a. The inner plates 50 on every two opposite inner side walls of the inner plates 50 on the four inner side walls are inwards bent towards each other to form bent plates, so that each inner plate 50 comprises a first bent part 50a and a second bent part 50b, a contraction mixing section is formed between the four first bent parts 50a, a diffusion mixing section is formed between the four second bent parts 50b, and a space part of one side, far away from the air inlet part 20a, of the inner plate 50 forms a premixing section, thereby forming a Venturi structure.

In the illustrated embodiment, the lances 52 are mounted within the flame ports such that the lances 52 project from the inner wall surface of the mixing tube 26. This arrangement can keep the flame away from the inner wall surface of the mixing pipe 26, and avoid damage to the inner wall surface.

As shown in FIG. 1, a plurality of mixing tubes 26 are disposed on all four sidewalls of the shield 16. More specifically, each of the four side walls is formed by stacking a plurality of mixing pipes 26 in the vertical direction, the number of the stacking of the mixing pipes 26 in each side wall is the same, and the mixing pipes 26 are arranged in the horizontal direction and are uniformly aligned in the vertical direction. Wherein, each layer of any side wall is formed by connecting two mixing pipes 26 side by side, the connecting end of the two mixing pipes 26 is closed, the other end of the mixing pipe 26 opposite to the connecting end is an open structure, and the nozzle 24 is arranged at the open structure. This arrangement allows the number of venturi burners 20 to be significantly increased and the size and power of a single venturi burner 20 can be significantly reduced for the same amount of gas to be processed, thereby significantly reducing noise and flame length.

Of the four side walls of the shield 16, flame holes on two opposite side walls are opposite to each other to spray flames, and flame holes on the other two opposite side walls are opposite to each other to spray flames. For example, all the mixing tubes 26 on two opposite sidewalls are respectively disposed oppositely, and the flame holes on the mixing tubes 26 on two opposite sidewalls are respectively corresponding in position, so that during combustion, the flame holes on two opposite sidewalls form a pair spray. The flame can inhibit the spraying length of the flame of the other side in the opposite spraying, and prevent the flame from extending to contact with the opposite wall surface, so that the temperature of the wall cylinder exceeds the standard and the color is changed.

To achieve the above requirement, it is necessary that the heights of any two mixing pipes forming opposite spray nozzles on the two opposite side walls are substantially the same. However, due to the limitation of the existing manufacturing process, the specification and size of each venturi burner may not be the same, and therefore, when the venturi burners are assembled, a large cumulative error may be generated when a plurality of venturi burners are stacked continuously, so that a large error may exist in the heights of two mixing pipes forming opposite spray on two opposite sidewalls, thereby affecting the flame opposite spray effect. And the continuously accumulated errors make the assembly of the burner below more and more difficult, so that the structure is unstable.

Based on this, the utility model discloses be equipped with at least one difference of repair ring 21 between a plurality of venturi combustors 20 of installing in succession to eliminate the accumulative error that a plurality of venturi combustors 20 installed in succession and formed.

The design enables the injection type combustion device to inject air in a larger range, on one hand, the number of the burners can be obviously increased, the insufficient air injection amount of each burner is avoided, the mixed gas is injected and combusted from a plurality of flame holes, the flame is uniformly distributed on the inner wall surface of the protective cover formed by the whole mixing pipe 26, and the combustion flame is relatively shorter; on the other hand, at the periphery of the protection cover 16 formed by the mixing pipes 26, due to the injection action of the venturi burner 20, besides a part of peripheral air is injected into the venturi burner 20 to participate in combustion, a large amount of peripheral cold air can be led to the outside of the protection cover 16, that is, if the outer side of the mixing pipes 26 moves, so that the heat of the mixing pipes 26 is dissipated. The mixed gas flows through the inside of the mixing pipe 26, and the heat radiation effect of the protection mask 16 itself can be further enhanced.
