Abstract
The utility model discloses a combustion tube structure, including one end opening one end confined combustion tube body, the open end of combustion tube body be the air inlet, and this external one side of combustion tube is fixed with the recess board that damps down that appears, is equipped with ignition needle and sensing pin between board and the air inlet damping down, the below that lies in the board that damps down on the combustion tube body is equipped with two rows of slot boccas that are used for the burning side by side. The width of slot bocca is the 0.3 -0.5 millimeter. The shape of slot bocca is " Z " font form. Every row of slot bocca divide into the multistage. The utility model discloses the speed of processing production is faster, more does benefit to batch production, and manufacturing cost is lower, and it is more stable to burn, and it is better to dry by the fire barbi quality color and luster, and the taste is purer.
Description
Technical field
The utility model relates to a kind of baking oven combustion apparatus structure, particularly a kind of combustion tube structure.
Background technology
The port of existing combustion tube on the market makes, and be mostly pin hole honeycomb type, its shortcoming has: 1. pin hole is little and many, generally often propping up heating tube all wants 1000-2000 aperture, and process velocity is slow, needs skilled worker to process, be unfavorable for batch production, labour cost and drill bit consume high, and production cost is high; 2. the diameter of pin hole is bigger than normal, and generally at about 1.8-2.0mm, mixed effect does not have advantage, and aperture independent is in addition discontinuous, and the chance of flame arcing and cutoff increases, and makes combustion instability, dries barbi and also can be subject to certain impact.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model be to provide a kind of process velocity fast, be more conducive to the combustion tube structure produced in batches, production cost is lower, burning is more stable.
The utility model solves the technical scheme that its technical problem adopts: a kind of combustion tube structure, comprise the combustion tube body that one end open one end is closed, the openend of combustion tube body is air inlet, this external side of combustion tube is fixed with groove type banking fire plate, between banking fire plate and air inlet, be provided with ignition electrode and inductive needle, the below described combustion tube body being positioned at banking fire plate is provided with the slot bocca of two rows for burning side by side.
As the technical scheme improved further, the width of described slot bocca is 0.3-0.5 millimeter.
As preferred technical scheme, the width of described slot bocca is 0.4 millimeter.
As preferred technical scheme, the shape of described slot bocca is " Z " word shape.
As preferred technical scheme, the shape of described slot bocca is rectangular shape.
As preferred technical scheme, the shape of described slot bocca is wave-like.
As the technical scheme improved further, described slot bocca of often arranging is divided into multistage.
The beneficial effects of the utility model are: the speed faster (radium-shine cutting) of processing, be more conducive to batch production, production cost is lower, burns more stable.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
Fig. 1 is perspective view of the present utility model.
The structural representation of Fig. 2 to be slot bocca shape of the present utility model be " Z " font.
Fig. 3 is the shape of slot bocca of the present utility model is the structural representation of rectangle.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of combustion tube structure of the utility model, comprise the combustion tube body 1 that one end open one end is closed, the openend of combustion tube body is air inlet 2, this external side of combustion tube is fixed with groove type banking fire plate 3, between banking fire plate and air inlet, be provided with ignition electrode 4 and inductive needle 5, the below described combustion tube body being positioned at banking fire plate is provided with the slot bocca 6 of two rows for burning side by side.
As the technical scheme improved further, the width of described slot bocca is 0.3-0.5 millimeter.The width of slot can be selected according to the size of combustion tube power, and the width of slot realizes cutting different width by the cutting torch of replacing laser cutting machine.The width adequate of slot bocca in the power of different size, to reach best combustion efficiency.
As preferred technical scheme, the width of described slot bocca is 0.4 millimeter.The better effects if of this burning.
As preferred technical scheme, the shape of described slot bocca is " Z " word shape.This is the shape of a reasonable slot bocca, and sufficient combustion is stablized.
As preferred technical scheme, the shape of described slot bocca is rectangular shape.This is the shape of a reasonable slot bocca equally, and sufficient combustion is stablized.
As preferred technical scheme, the shape of described slot bocca is wave-like.This is the shape of a reasonable slot bocca equally, and sufficient combustion is stablized.
As the technical scheme improved further, described slot bocca of often arranging is divided into multistage.Be divided into the multistage of suitable length, can reduce and eliminate the changes of slit length that high temperature deformation causes, be conducive to sufficient combustion and stablize.
The utility model relates to food-baking field, for naked light baked goods, working method is: inject in combustion tube after combustion gas mixes with air proportion, from the narrow slit tube wall, i.e. slot bocca effusion, the ignition electrode sparking of outlet top is lighted, flame is covered with whole slot bocca, smooth combustion, makes homogeneous temperature in the space of relative closure raise, for food-baking provides stable curing environment.
Material of the present utility model is wall thickness is 4-5mm, the carbon steel seamless steel pipe of external diameter 40-80mm, and inlet end is gas thread, is connected with the gas pipeline mixed.Combustion tube body is combustion heating district, sprays fuel gas buring by radium-shine Z-type or rectangle or the waveform slot bocca that burns.Combustion zone stainless steel banking fire plate 3 stabilizes the flame, and ensures homogenous combustion not arcing.
The utility model adopts laser cutting machine to cut out narrow slit in pipe side, and combustion gas is evenly overflowed from gap.The damping effect of narrow slit is that combustion gas mixing and outlet pressure are more tending towards balanced, and homogeneous heating in combustion tube total length, is heated evenly about can ensureing baking oven, and the product color baked is consistent.Narrow slit is pressed rectangle or Z-shaped or waveform and is arranged, and ensures that certain flame width is to provide enough heats, can ensure flame stabilization in addition, there will not be the phenomenon of arcing and local misfire.And sufficient combustion, energy-conservation; Combustion tube Z-type slot machining is convenient, with low cost.
In addition, the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with substantially identical means, all should belong to protection domain of the present utility model.
