Description

Technical Field

[0001] The utility model belongs to the technical field of steam exhaust silencing, and in particular relates to a steam exhaust device for an aerated concrete autoclave with a silencing mechanism. Background Art

[0002] Autoclave, also known as steam curing autoclave or pressure autoclave, is a large pressure vessel with huge volume and heavy weight. Autoclave has a wide range of uses, and is widely used in the autoclave curing of aerated concrete blocks, concrete pipe piles, lime sand bricks, fly ash bricks, microporous calcium silicate boards, new lightweight wall materials, thermal insulation asbestos boards, high-strength gypsum and other building materials.

[0003] After the autoclave is completed, the high-temperature and high-pressure gas inside the autoclave needs to be discharged through the exhaust pipe. Due to the high gas pressure, the exhaust noise from the exhaust pipe is relatively large, which causes serious noise interference to the production environment. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide an exhaust device for an aerated concrete autoclave with a silencer mechanism.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] An exhaust device for an aerated concrete autoclave with a silencer mechanism comprises an exhaust pipe, wherein the exhaust pipes are fixedly connected by a connecting flange, and further comprises a first honeycomb silencer plate and a second honeycomb silencer plate;

[0007] The inner cavity at one side of the exhaust pipe flange end is expanded outward to form a first step cavity and a second step cavity, the second step cavity is outside, the first step cavity is inside, and the shape of the first step cavity is a cut circle;

[0008] The first honeycomb muffler plate is provided with a first main body adapted to the shape of the inner cavity, the circumference of the first main body is provided with a cut-circle outer edge adapted to the shape of the second stepped cavity, the second honeycomb muffler plate is provided with a cut-circle main body adapted to the shape of the first stepped cavity, the circumference of the cut-circle main body is provided with a second outer edge adapted to the shape of the second stepped cavity;

[0009] A filling rubber strip is embedded in the second outer edge end surface of the second honeycomb sound-absorbing plate, and the filling rubber strip protrudes from the second outer edge end surface.

[0010] It is further defined that the first honeycomb sound-absorbing plate is provided with a first sound-absorbing hole, and the second honeycomb sound-absorbing plate is provided with a second sound-absorbing hole. With such a structural design, the first sound-absorbing hole and the second sound-absorbing hole are used to attenuate noise, thereby reducing the sound of the gas itself and the sound of the gas hitting the exhaust pipe during exhaust, thereby achieving a sound-absorbing effect.

[0011] It is further defined that the outer end surface of the second honeycomb silencer plate is provided with a first gas diffusion groove, the inner end surface of the second honeycomb silencer plate is provided with a second gas diffusion groove, and the two ends of the second silencer hole are respectively connected to the first gas diffusion groove and the second honeycomb silencer plate. With such a structural design, the second gas diffusion groove mainly functions to merge the gas flowing out of the first honeycomb silencer plate into the second silencer hole of the second honeycomb silencer plate, and the first gas diffusion groove mainly functions to merge the gas flowing out of the second honeycomb silencer plate into the second honeycomb silencer plate of the adjacent exhaust pipe, thereby improving the smoothness of gas flow.

[0012] It is further defined that the outer end surface of the second honeycomb sound-absorbing plate is provided with an embedding groove for embedding the filling rubber strip. With such a structural design, the embedding groove is used for embedding the filling rubber strip.

[0013] It is further defined that trumpet-shaped expansion openings are provided at both ends of the first silencer hole and the second silencer hole. With such a structural design, the expansion openings gather airflow and assist the airflow to enter the first silencer hole and the second silencer hole.

[0014] The beneficial effects of the utility model are as follows: the exhaust pipes are fixedly connected by connecting flanges, and tightening pressure is applied between the two exhaust pipes by bolts on the connecting flanges, and the tightening pressure also serves as the pressing force of the first honeycomb silencer plate and the second honeycomb silencer plate at the connection of the two exhaust pipes. This fixing method avoids the trouble of welding inside the exhaust pipe and the inconvenience of operation, and has a simpler structure and more convenient installation. The honeycomb structure of the first honeycomb silencer plate and the second honeycomb silencer plate is used to attenuate noise, thereby reducing the sound of the gas itself and the sound of the gas hitting the exhaust pipe during exhaust, thereby achieving a silencing effect.

[0032] In this embodiment:

[0033] The exhaust pipes 1 are fixedly connected by the connecting flange 11, and the bolts on the connecting flange 11 apply a tightening pressure between the two exhaust pipes 1. The tightening pressure also serves as the pressing force of the first honeycomb muffler plate 2 and the second honeycomb muffler plate 3 at the connection of the two exhaust pipes 1. This fixing method avoids the trouble of welding inside the exhaust pipe 1, which is inconvenient to operate, and has a simpler structure and is more convenient to install.

[0034] Specifically, the first body 21 of the first honeycomb muffler plate 2 enters the inner cavity of the exhaust pipe 1, and the outer edge 22 of the cut circle enters the second stepped cavity 14. The cut circle has a stop function of the circumferential freedom to prevent the first honeycomb muffler plate 2 from rotating. The cut circle body 31 of the second honeycomb muffler plate 3 enters the first stepped cavity 13 and is also restricted in rotational freedom. After the two sections of the exhaust pipe 1 are connected, the filling strip 4 fills the gap between the second honeycomb muffler plates 3 at the ends of the two sections of the exhaust pipe 1.

With such a structural design, the embedding groove 34 is used to embed the filling rubber strip 4. In fact, other installation structures of the filling rubber strip 4 can also be considered according to specific circumstances.

[0039] Preferably, trumpet-shaped expansions are provided at both ends of the first muffler hole 23 and the second muffler hole 36. With such a structural design, the expansions gather airflow and assist airflow to enter the first muffler hole 23 and the second muffler hole 36.
