Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, distributor 2 upper end connects inner fire cover 11, middle fire cover 12, outer fire cover 13, connects outer induction tunnel 31 and interior induction tunnel 32 in the lower end of distributor 2.The combustion gas output of interior induction tunnel 32 is arranged in outer induction tunnel 31.
As shown in Fig. 1 to 5, a kind of three ring fire distributor 2, distributor 2 upper end arranges outer shroud air flue 211, middle ring air flue 212, inner ring air flue 213, and distributor 2 lower end connects outer induction tunnel 31, interior induction tunnel 32.
As shown in Figures 2 to 4, distributor 2 arrange at least 2 around distributor center radially equally distributed radial air flue 217, the present embodiment preferentially arranges 4 radial air flues 217, the inlet end of radial air flue 217 is arranged at the center of distributor 2, the inlet end of radial air flue 217 is communicated with outer induction tunnel 31, outlet side is communicated with outer shroud air flue 211 and middle ring air flue 212, and the lower end of inner ring air flue 213 is arranged in the inlet end of radial air flue 217, and the lower end of inner ring air flue 213 is communicated with interior induction tunnel 32.
Distributor 2 structure of the present embodiment is simple, airway patency.The inlet end of radial air flue 217 is arranged at the middle part of distributor 2 lower surface, same ring air flue is identical with the distance of the inlet end of radial air flue 217 everywhere, namely the length of the radial air flue 217 of every bar is also the same, in delivery of fuel gas process, gaseous-pressure is along with the conveying of radial air flue 217, and reduce gradually, same delivered length is in same ring air flue, identical with the gaseous-pressure of the junction of radial air flue 217.Therefore be convenient in the present embodiment arrange rational outer shroud air flue 211, middle ring air flue 212, inner ring air flue 213, make the pressure distribution of each ring air flue even.
Radial air flue 217 annular is uniformly distributed, and is convenient to combustion gas and can flows to each ring air flue evenly unobstructedly.
As shown in Figure 2 and Figure 3, the inlet end of radial air flue 217 arranges annular air channel 218, and inner ring air flue 213 is arranged in annular air channel 218.The ventilation cross section of annular air channel 218 is greater than the ventilation cross section of radial air flue 217, and annular air channel 218 bottom is communicated with outer induction tunnel 31, and the outer ring surface of annular air channel 218 connects radial air flue 217, and is communicated with radial air flue 217.Annular air channel 218 forms the larger annular housing of a volume, be convenient to slow down flow velocity, stablize annular air channel 218 pressure everywhere, gas-flow can be avoided to cause the gas-flow flowing to each radial air flue 217 to disorder to change, avoid the pressure of the inlet end of each radial air flue 217 inconsistent, make the combustion gas after reduced velocity flow can flow to outer shroud air flue 211 and middle ring air flue 212 by radial air flue 217 uniformly smoothly.
As shown in Figure 5, arrange middle ring secondary-air passage 215 between outer shroud air flue 211 and middle ring air flue 212, middle ring secondary-air passage 215 up/down perforation is arranged.Arrange inner ring secondary-air passage 216 between middle ring air flue 212 and inner ring air flue 213, inner ring secondary-air passage 216 up/down perforation is arranged.Carry out auxiliary air compensation, up/down perforation when burning to each ring air flue by above-mentioned two air ducts, the secondary-air passage of each ring fire is separated from each other, and replenish air is simply effective, ensures that replenish air amount is sufficient.
The top of annular air channel 218 is set to taper surface, the lower inside of middle ring air flue 212 is set to taper surface, taper surface is convenient to guide air to enter inner ring secondary-air passage 216, the inner ring taper surface of middle ring air flue 212 coordinates with the taper surface of annular air channel 218 breathing area adding inner ring secondary-air passage 216, adds air vent amount.Outer shroud air flue 211 outer lower portion is set to taper surface, arranges taper surface herein and is convenient to the secondary-air passage that auxiliary air enters distributor bottom.
The present embodiment distributor is split type, and as shown in Figure 3, distributor 2 arranges main part 21, bottom 22.The cover plate 222 that bottom 22 comprises annulus 221 and is connected with annulus 221, the corresponding annular air channel 218 of annulus 221 is arranged, and the corresponding radial air flue 217 of cover plate 222 is arranged.
The distributor 2 of split-type structural arranges main part 21 and bottom 22, main part 21 and cover plate 22 are without inner chamber parts, when Foundry Production, main part 21 and bottom 22 designing mould respectively, decrease the die cavity core in mould, mould structure is more simple, greatly reduces the technology difficulty of production, the producting process difficulty of whole distributor 2 is reduced.
Distributor 2 arranges the connector 214 for connecting main part 21 and bottom 22, and annulus 221 arranges fixing ear 223, arranges holder 219 in annular air channel 218, and connector 214 one end is connected and fixed ear 223, and the other end is fixed on holder 219.Connector 214 entirety is all fixed in blast tube, and not direct and contacting external air, reduces the time contacted with air.When distributor 2 works, connector 214 is in the condition of high temperature, especially can avoid contacting with air under the condition of high temperature, effectively can slow down connector 214 corrosion, it is few that the connected mode of the present embodiment also has installation procedure, is conducive to the feature that rapid batch is produced.In the present embodiment, connector 214 is rivet or screw.
The present embodiment combustion gas enters distributor 2 from outer induction tunnel 31 and interior induction tunnel 32 respectively, outer induction tunnel 31 is communicated with outer shroud air flue 211 and middle ring air flue 212, first the combustion gas of outer induction tunnel 31 enters annular air channel 218, after stablizing flow velocity and pressure, branch to the radial air flue 217 of each bar, enter middle ring air flue 212 and outer shroud air flue 211 by radial air flue 217.The combustion gas of interior induction tunnel 32 enters inner ring air flue 213.Outer shroud air flue 211, middle ring air flue 212 and inner ring air flue 213 arrange external ring fire cover 13, middle ring fire cover 12, interior ring fire cover 11 respectively, and the combustion gas entering each ring air flue is burnt at each ring fire cover place.
The utility model structure is simple, technique simple, and distributor 2 blast tube is evenly distributed, and air-flow is unobstructed, and each ring gaseous-pressure of outer fire cover 13, middle fire cover 12 and inner fire cover 11 is evenly distributed, and each ring secondary-air passage is separated from each other, and auxiliary air supplements sufficient.
In addition, main part 21 and the bottom 22 of the present embodiment distributor 2 also can adopt integral structure, and adopt Integral sand casting to manufacture and produce, remainder structure all with reference to above-mentioned split type distributor structure, does not repeat at this one by one.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
