Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with accompanying drawing and reality Apply example, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only Only in order to explain the present invention, it is not intended to limit the present invention.
As shown in figure 1, distributor 2 upper end connects inner fire cover 11, middle fire cover 12, outer fire cover 13, dividing The lower end of firearm 2 connects outer induction tunnel 31 and interior induction tunnel 32.The combustion gas outfan setting of interior induction tunnel 32 In outer induction tunnel 31.
As shown in Fig. 1 is to 5, a kind of three ring fire distributor 2, distributor 2 upper end setting outer shroud air flue 211, Medium ring air flue 212, internal ring air flue 213, distributor 2 lower end connects outer induction tunnel 31, interior induction tunnel 32.
As shown in Figures 2 to 4, distributor 2 arranges at least 2 around the radially even distribution in distributor center Radial direction air flue 217, the present embodiment preferentially arranges 4 radial direction air flues 217, and the inlet end of radial direction air flue 217 sets It is placed in the center of distributor 2, the inlet end of radial direction air flue 217 connects outer induction tunnel 31, and outlet side is even Logical outer shroud air flue 211 and medium ring air flue 212, the lower end of internal ring air flue 213 is arranged at radial direction air flue 217 In inlet end, induction tunnel 32 in the lower end connection of internal ring air flue 213.
Distributor 2 structure of the present embodiment is simple, airway patency.The inlet end of radial direction 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 direction air flue 217 everywhere, I.e. the length of every radial direction air flue 217 is also the same, and during delivery of fuel gas, gaseous-pressure is with radially The conveying of air flue 217, and being gradually lowered, same delivered length, in same ring air flue, with radial direction gas The gaseous-pressure of the junction in road 217 is identical.Therefore it is easy in the present embodiment arrange rational outer shroud air flue 211st, medium ring air flue 212, internal ring air flue 213, makes the pressure distribution of each ring air flue uniform.
Radial direction air flue 217 annular is uniformly distributed, and is easy to combustion gas and can flow to each ring air flue uniformly unobstructedly.
As shown in Figure 2 and Figure 3, the inlet end setting annular air channel 218 of radial direction air flue 217, internal ring air flue 213 are arranged in annular air channel 218.The ventilation section of annular air channel 218 is more than the logical of radial direction air flue 217 Gas section, annular air channel 218 bottom connects outer induction tunnel 31, and the outer ring surface of annular air channel 218 connects radially Air flue 217, and connect with radial direction air flue 217.Annular air channel 218 forms the larger annular chamber of a volume Body, is easy to slow down flow velocity, stablizes annular air channel 218 pressure everywhere, it can be avoided that combustion gas flows to change drawing Act the combustion gas flow direction disorder flowing to each radial direction air flue 217, it is to avoid the inlet end of each radial direction air flue 217 Pressure is inconsistent so that the combustion gas after reduced velocity flow can smoothly uniformly be flowed to by radial direction air flue 217 Outer shroud air flue 211 and medium ring air flue 212.
As shown in figure 5, arranging medium ring secondary-air passage 215 between outer shroud air flue 211 and medium ring air flue 212, Medium ring secondary-air passage 215 up/down perforation is arranged.Arrange between medium ring air flue 212 and internal ring air flue 213 Internal ring secondary-air passage 216, internal ring secondary-air passage 216 up/down perforation is arranged.By above-mentioned two Air duct carries out auxiliary air compensation, up/down perforation, the secondary sky of each ring fire in burning to each ring air flue Gas passage is separated from each other, and air supplements simply effectively it is ensured that air magnitude of recruitment is sufficient.
The top of annular air channel 218 is set to taper surface, and the lower inside of medium ring air flue 212 is set to taper surface, Taper surface is easy to guide air to enter internal ring secondary-air passage 216, the internal ring taper surface of medium ring air flue 212 Taper surface cooperation with annular air channel 218 increased the breathing area of internal ring secondary-air passage 216, increases Air vent amount.Outer shroud air flue 211 outer lower portion is set to taper surface, and setting taper surface is easy to secondary sky herein Gas enters the secondary-air passage of distributor bottom.
The present embodiment distributor is split type, as shown in figure 3, distributor 2 setting main part 21, bottom 22.Bottom 22 includes annulus 221 and the cover plate 222 being connected with annulus 221, the corresponding annular of annulus 221 Air flue 218 is arranged, and the corresponding radial direction air flue 217 of cover plate 222 is arranged.
The distributor 2 setting main part 21 of split-type structural and bottom 22, main part 21 and cover plate 22 are equal For no inner chamber part, in Foundry Production, main part 21 and bottom 22 separately design mould, decrease mould Die cavity core in tool, mould structure is simpler, greatly reduces the technology difficulty of production, makes whole The producting process difficulty of distributor 2 reduces.
Distributor 2 is provided for connecting the connector 214 of main part 21 and bottom 22, and annulus 221 is arranged Fixing ear 223, setting fixed seat 219 in annular air channel 218, connector 214 one end is connected ear 223, The other end is fixed on fixed seat 219.Connector 214 is overall to be both secured in blast tube, not directly with outward Boundary's air contact, reduces the time with air contact.When distributor 2 works, connector 214 is in high temperature State, especially it can be avoided that under the condition of high temperature with air contact, can effectively slow down connector 214 and become rusty Erosion, the connected mode of the present embodiment also has that installation procedure is few, is conducive to the feature that rapid batch produces.This In embodiment, connector 214 is rivet or screw.
The present embodiment combustion gas enters distributor 2, outer induction tunnel from outer induction tunnel 31 and interior induction tunnel 32 respectively 31 connection outer shroud air flues 211 and medium ring air flue 212, the combustion gas of outer induction tunnel 31 initially enters annular air channel 218, after stablizing flow velocity and pressure, branch to each bar radial direction air flue 217, entered by radial direction air flue 217 Medium ring air flue 212 and outer shroud air flue 211.The combustion gas of interior induction tunnel 32 enters internal ring air flue 213.Outer shroud gas Road 211, medium ring air flue 212 and internal ring air flue 213 are respectively provided with external ring fire cover 13, middle ring fire cover 12, interior Ring fire cover 11, the combustion gas entering each ring air flue is burnt at each ring fire cover.
Present configuration is simple, process is simple, and distributor 2 blast tube is evenly distributed, and air-flow is unobstructed, outward Fire cover 13, middle fire cover 12 and each ring gaseous-pressure of inner fire cover 11 are evenly distributed, and each ring secondary-air passage Separated from each other, auxiliary air supplements sufficient.
In addition, the main part 21 of the present embodiment distributor 2 may also be employed integral structure with bottom 22, adopt Manufactured with Integral sand casting and produce, remainder structure is all with reference to above-mentioned split type distributor structure, here Do not repeat one by one.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention not office Be limited to this, any those familiar with the art the invention discloses technical scope in, can be easily The change or replacement expected, all should be included within the scope of the present invention.Therefore, the protection of the present invention Scope should be defined by scope of the claims.
