It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] See also Figure 1-Figure 7 The utility model provides a technical solution: a tubular silencer for a combustion-supporting fan, the tubular silencer for a combustion-supporting fan comprising: a combustion-supporting fan body 1, a threaded tube 2 is arranged at one end of the combustion-supporting fan body 1, and a limited through hole 3 is arranged on the surface of the threaded tube 2; a tubular silencer 4, a connecting pipe 5 is arranged at one end of the tubular silencer 4, a positioning nut 6 is screwed on the surface of the connecting pipe 5, a bearing 7 is arranged on the side of the positioning nut 6, a vertical plate 8 is arranged on the surface of the bearing 7, a limiting rod 9 is arranged in the vertical plate 8, and a positioning plate 10 is arranged on the end surface of the connecting pipe 5;

[0026] When in use, the tubular silencer 4 can be used to reduce noise and silence the combustion-supporting fan main body 1. When the inside of the tubular silencer 4 needs to be inspected and repaired, the limiting rod 9 is first pulled out from the limiting groove 13, and then the positioning nut 6 can be rotated to make the positioning nut 6 lose its limiting effect on the threaded tube 2, so that the tubular silencer 4 can be removed from one end of the combustion-supporting fan main body 1 for more convenient inspection and repair.

[0027] Embodiment 2

[0028] On the basis of the first embodiment, in order to facilitate the silencing of the combustion-supporting fan body 1, a tubular muffler 4 is provided, a sound insulation cotton 11 is provided on the end face of the connecting pipe 5, a thread is provided on the outer ring surface of the connecting pipe 5, and the positioning nut 6 can be screwed on the connecting pipe 5 and the threaded pipe 2 at the same time. A sound insulation pipe 14 is sleeved on the surface of the tubular muffler 4, and a placement groove is provided on the end face of the sound insulation pipe 14, and a sound insulation fence 15 is provided in the placement groove;

[0029] When in use, the tubular silencer 4 can be used to silence the combustion-supporting fan main body 1 to prevent the combustion-supporting fan main body 1 from generating large noises that affect the work of the staff. The sound insulation cotton 11 arranged at the connection between the tubular silencer 4 and the combustion-supporting fan main body 1 can prevent the noise generated by the combustion-supporting fan main body 1 from being released from the connection between the tubular silencer 4 and the combustion-supporting fan main body 1. The setting of the sound insulation cotton 11 can reduce the external release of noise. The setting of the sound insulation pipe 14 cooperates with the sound insulation fence 15 arranged inside to make the inside of the sound insulation pipe 14 hollow, which can further improve the sound insulation effect of the tubular silencer 4.

[0030] Embodiment 3

[0031] On the basis of the second embodiment, in order to improve the stability of the connection between the tubular muffler 4 and the combustion-supporting fan body 1, a limit rod 9 is provided, one end of the vertical plate 8 is fixedly connected to the surface of the bearing 7, and the vertical plate 8 can be rotated by using the bearing 7. A hole is provided on the surface of the vertical plate 8, and the limit rod 9 can move up and down in the hole provided on the surface of the vertical plate 8. A spring 12 is sleeved on the surface of the limit rod 9, one end of the spring 12 is fixedly connected to the surface of the limit rod 9, and the other end of the spring 12 is fixedly connected to the surface of the vertical plate 8. A plurality of groups of positioning plates 10 are provided, and the plurality of groups of positioning plates 10 are regularly arranged in a circle around the center point of the end surface of the connecting pipe 5. A limiting groove 13 is provided on the surface of one group of positioning plates 10, and one end of the limiting rod 9 can be inserted into the limiting groove 13;

[0032] When in use, after the tubular silencer 4 is connected to the combustion-supporting fan body 1 by using the positioning nut 6, the limiting rod 9 can be cooperated with the spring 12 to insert one end of the limiting rod 9 into the limiting groove 13, so as to avoid the problem of loosening of the positioning nut 6 caused by the vibration generated when the combustion-supporting fan body 1 works for a long time. The limiting rod 9 can be used to limit the positioning nut 6 without causing the problem of vibration displacement. The setting of the bearing 7 also avoids the problem of rotating the positioning nut 6 causing the limiting rod 9 to rotate.

[0033] In actual use, the tubular silencer 4 can be used to reduce noise and silence the combustion-supporting fan main body 1. When the inside of the tubular silencer 4 needs to be inspected, the limiting rod 9 is first pulled out from the limiting groove 13, and then the positioning nut 6 can be rotated to make the positioning nut 6 lose the limiting effect on the threaded tube 2, so that the tubular silencer 4 can be removed from one end of the combustion-supporting fan main body 1 for maintenance, which is more convenient. This avoids the traditional tubular silencer equipment that is mainly installed on the combustion-supporting fan main body 1 by welding or multiple sets of bolts. Therefore, when the inside of the tubular silencer equipment needs to be inspected, the tubular silencer equipment fixed by welding or multiple sets of bolts is more troublesome to disassemble.
