Description

Ring piece type silencer

Technical Field

The utility model relates to a silencer, in particular to a ring-piece silencer.

Background

The silencing principle of the silencer is that the original first forward-propagating sound wave returns to the original point by using a proper combination of a cavity and a pipe and by using the reflection of a plurality of interfaces, and then returns back to the original point to propagate forwards again, and the point is merged with a second forward-propagating sound wave which is not reflected, and the two waves are equal in amplitude and further cancel each other.

However, the arrangement of the silencing material in the existing silencer often has a larger interval, and although part of sound waves generated during the operation of the equipment is absorbed by the silencing plates, part of sound waves still penetrate through gaps between the silencing plates, and the part of sound waves are not absorbed and are not subjected to buffering and offsetting treatment, so that the silencing effect of the silencer is poor if the sound waves directly penetrate through the silencer and are discharged.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1 to 5, a ring-type muffler includes: a hollow chamber 2; a connector 1 communicated with the equipment; an outlet 3 arranged in the opposite direction of the connector 1; a plurality of silencing groups 4 arranged inside the chamber 2; the silencing group 4 comprises an installation tube 41 and a plurality of silencing structures 43 inserted in the installation tube 41, wherein the projection positions of the silencing structures 43 are partially overlapped with the surfaces of two adjacent silencing structures 43.

In the silencer, sound waves are partially silenced in a mode of mutually cancelling the sound waves, so the sound waves are required to be blocked, and when the projection positions of the silencing structures 43 are partially overlapped, the silencing surface formed by the silencing structures 43 can cover the outlet 3 of the whole cavity 2, so that the sound waves which are not subjected to silencing treatment are prevented from being partially transmitted out from the outlet 3, and the whole noise is improved.

Furthermore, the circumscribed circle of the silencing group 4 seals the inner wall of the chamber 2, and the silencing structures 43 on the silencing group 4 on the same straight line are arranged in a staggered manner, because the silencing structures 43 are of trapezoidal plate structures, gaps are inevitably formed after the silencing structures 43 are in contact with the chamber 2, and if the silencing structures 43 on other silencing groups 4 are arranged in a staggered manner, the projection positions of the silencing structures 43 on different planes can be staggered with each other, so that all sound waves passing through the chamber 2 can be subjected to the silencing effect of the silencing structures 43, and the integral silencing efficiency is improved.

Further, the muffler set 4 further includes a mounting shaft 42, a notch 21 is formed at a top end of an inner side wall of the chamber 2, and a traveling structure 44 is connected between the mounting shaft 42 and the notch 21, in this embodiment, the traveling structure 44 includes an extending arm 441 connected to the mounting shaft 42, and a linear motor 442 fixed to a top of the extending arm 441 and movably connected in the notch 21, because lengths of pipes to be arranged are different, depths to which the muffler set 4 needs to be arranged are also different, and by arranging the linear motor 442, the extending arm 441 is connected to the muffler set 4 and the linear motor 442, that is, the muffler set 4 can be driven by the linear motor 442 to move in the chamber 2, and a distance between different muffler sets 4 is set according to the length of the chamber 2, in other embodiments, other structures capable of moving linearly can be used, the silencing group 4 can be driven to do linear motion.

Further, the linear motor 442 is wirelessly connected with an external control terminal, and a wireless control mode is adopted, so that wiring in the pipeline can be avoided, on one hand, the work load can be reduced, the time wasted by wire arrangement and wiring can be reduced, on the other hand, the circuit can be prevented from being corroded in the pipeline, and the cost is reduced.

In order to reserve certain passageway for the sound wave, the interval between the noise elimination board 433 is greater than more than 5cm, but is not more than 10cm, can let the sound wave when passing through two noise elimination boards 433, can receive the noise cancelling effect of two noise elimination boards 433 simultaneously, if the interval undersize between the two, then probably cause great hindrance to the propagation of sound wave, and then cause the damage to noise elimination board 433 itself, if the interval between the two is too big, then the sound wave directly passes through two noise elimination boards 433 easily, can't play the effect of noise elimination.

Because the sound waves generate heat energy after contacting the sound-absorbing plate 433 and the sound waves collide with each other and offset each other, the contact position of the sound-absorbing plate 433 and the chamber 2 is provided with the heat-conducting cotton 443, the heat-conducting cotton 443 can discharge the generated heat in time, and the heat-conducting cotton 443 itself also has a certain sound-absorbing effect.

Furthermore, the heat conduction cotton 443 is filled between the two sound-absorbing plates 433, so that the gap between the sound-absorbing plates 433 can be blocked, the gap between the sound-absorbing plates 433 of the heat conduction cotton 443 can achieve a partial sound-absorbing effect, and the functions of sound absorption, blocking and heat conduction are integrated.

Furthermore, the inner side wall of the chamber 2 is further provided with a silencing net 22, which can primarily absorb the sound wave oscillating in the chamber 2, and the sound wave can be pretreated before reaching the silencing group 4.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
