Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm soot blowers, and particularly relates to a bend flange of a diaphragm soot blower. Background Technique

[0002] A diaphragm soot blower is the abbreviation of a diaphragm type acoustic soot blower. It utilizes the vibration of high-frequency sound waves to make the air flow at an extremely high speed, thereby causing unevenness of the air, forming a vortex phenomenon of high-pressure air flow and low-pressure air flow, and the sound successively contacts and diffuses with the contacted surface after passing through the conduction and sound amplification pipeline, so that the dust diffuses into the surrounding environment under the action of the air flow, thereby achieving the purpose of cleaning the surface.

[0003] At present, due to the reasons of inability to be integrally processed and inconvenient transportation, the sound amplification pipe of the diaphragm soot blower usually consists of three sections: a horn-shaped sound amplification cylinder, a bent pipe, and a sound guiding pipe for the sound emission of the sound generator. After the sound amplification cylinder, the bent pipe, and the sound guiding pipe for the sound emission of the sound generator reach the use site, they need to be reassembled based on the flange. However, in use, we found that the flanges connected to both ends of the bent pipe are only installed by bolt riveting, and the vibration of the sound wave conduction will cause the sealing performance between the flanges to decrease, resulting in the weakening of the sound wave conduction vibration process and the reduction of the surface cleaning effect of the equipment.

[0004] Based on the existing bend flange of the diaphragm soot blower, there are the following disadvantages: there is no set of butt flanges for the bend that can improve the connection sealing performance between the bends of the diaphragm soot blower. Therefore, we propose a bend flange of a diaphragm soot blower. Summary of the Invention

[0005] The main purpose of the utility model is to provide a bend flange of a diaphragm soot blower, which can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A bend flange of a diaphragm soot blower includes an expansion bend pipe, a diaphragm type acoustic wave generator, and a sound amplification cylinder, and also includes a sound guiding pipe, an annular groove, and an annular protrusion. The expansion bend pipe is located between the sound guiding pipe and the sound amplification cylinder. The sound inlet end of the sound guiding pipe is welded to the sound emission end of the diaphragm type acoustic wave generator. The two ends of the expansion bend pipe are respectively welded with a first bend flange and a second bend flange. The sound inlet end of the sound amplification cylinder and the sound emission end of the sound guiding pipe are respectively welded with a sound cylinder flange and a sound pipe flange corresponding to the first bend flange and the second bend flange.

[0008] Furthermore, annular grooves are respectively opened on the covering surfaces of the first bend flange and the second bend flange, and annular protrusions corresponding to the annular grooves are respectively provided on the covering surfaces of the sound cylinder flange and the sound pipe flange.

[0009] Further, the annular protrusions on the horn flange and the sound pipe flange are respectively inserted into the annular grooves on the corresponding first bend flange and the second bend flange.

[0010] Further, a rubber sealing ring is glued to the end face of the annular protrusion.

[0011] Further, the horn flange and the sound pipe flange are respectively installed and connected to the corresponding first bend flange and the second bend flange through bolts.

[0012] Compared with the prior art, the utility model has the following beneficial effects: Through the annular grooves on the first bend flange and the second bend flange, and the annular protrusions and rubber sealing rings on the horn flange and the sound pipe flange, the connection tightness between the flanges can be increased when the sound amplification elbow is butt - jointed and installed with the sound amplification horn and the sound guiding pipe, solving the problem that during the propagation of sound waves in the sound amplification pipe, the weak sealing between the flanges leads to the weakening of the vibration of sound wave conduction and the reduction of the soot blowing effect.

[0018] Such as Figures 1 - 3As shown in the figure, a bend flange of a diaphragm soot blower includes an acoustic horn 3, a diaphragm type acoustic wave generator 1, and an acoustic horn 4. It also includes a sound guide pipe 2, an annular groove 11, and an annular protrusion 9. The acoustic horn 3 is located between the sound guide pipe 2 and the acoustic horn 4. The inlet end of the sound guide pipe 2 is welded to the sound emitting end of the diaphragm type acoustic wave generator 1. The two ends of the acoustic horn 3 are respectively welded with a first bend flange 5 and a second bend flange 6. The inlet end of the acoustic horn 4 and the sound discharging end of the sound guide pipe 2 are respectively welded with a horn flange 7 and a sound pipe flange 8 corresponding to the first bend flange 5 and the second bend flange 6. Annular grooves 11 are respectively formed on the mating surfaces of the first bend flange 5 and the second bend flange 6. Annular protrusions 9 corresponding to the annular grooves 11 are respectively provided on the mating surfaces of the horn flange 7 and the sound pipe flange 8. The annular protrusions 9 on the horn flange 7 and the sound pipe flange 8 are respectively inserted into the corresponding annular grooves 11 on the first bend flange 5 and the second bend flange 6. A rubber sealing ring 10 is glued to the end face of the annular protrusion 9. The horn flange 7 and the sound pipe flange 8 are respectively installed and connected to the corresponding first bend flange 5 and second bend flange 6 by bolts.

[0019] It should be noted that the present utility model is a bend flange of a diaphragm soot blower. During operation, the operator covers the first bend flange 5 and the second bend flange 6 at both ends of the acoustic horn 3 on the horn flange 7 and the sound pipe flange 8 of the acoustic horn 4 and the sound guide pipe 2 respectively, and ensures that the annular protrusion 9 with the rubber sealing ring 10 is inserted into the annular groove 11. Subsequently, the first bend flange 5 and the second bend flange 6 of the acoustic horn 3 are bolted to the horn flange 7 and the sound pipe flange 8 of the acoustic horn 4 and the sound guide pipe 2 respectively through bolts. Based on the insertion of the annular protrusion 9 into the annular groove 11 and the padding of the rubber sealing ring 10, the acoustic amplification structure of the overall diaphragm soot blower is fully sealed, so that the acoustic wave propagation will not be significantly weakened after long-term use, and the stability of soot blowing can be effectively guaranteed.
