Abstract

The utility model discloses an integrated exhaust muffler. Including, a diffuser, a sound-absorbing section, an inlet, and an outlet; the muffler is provided with a plurality of inlets, and the inlet is connected to the diffuser; There is an outlet; the diffuser is made of a plurality of sound-absorbing cylinders, and the sound-absorbing holes are arranged on the sound-absorbing cylinders; a plurality of sound-absorbing plates are arranged in the sound-absorbing section, and sound-absorbing micropores are arranged in a staggered arrangement on the sound-absorbing plates; The utility model adopts a plurality of sound-absorbing tubes to depressurize and remove noise step by step, so that the high-pressure air flow will not cause damage to the internal parts of the muffler; the air flow passes through the diffuser and the sound-absorbing section twice to silence the noise, which improves the sound-absorbing effect; The inlet can be connected to multiple exhaust outlets of medium and high pressure equipment at the same time, and can reduce noise and silence various exhaust gases, save floor space and reduce enterprise costs, which has good promotion value.

Description

Integrated exhaust muffler

technical field

The utility model relates to a muffler, in particular to an integrated exhaust muffler.

Background technique

The original muffler has the following disadvantages: (1) It can only decompress the exhaust gas of a single medium and high pressure equipment. If it is necessary to depressurize multiple exhaust gases at the same time, multiple mufflers need to be installed at the same time, which occupies a large area and increases the production capacity of the enterprise. Cost; (2) Most of the original mufflers only use small hole injection to reduce pressure and reduce noise or sound-absorbing panels to absorb and reduce noise. The noise reduction effect of a single noise reduction device is not obvious. At the same time, high-pressure airflow directly entering the inside of the muffler will cause damage to the internal components .

The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and should not be considered as an acknowledgment or in any form to imply that the information constitutes the prior art already known to those skilled in the art.

Utility model content

The purpose of this utility model is to provide an integrated exhaust muffler, so as to overcome the above-mentioned defects in the prior art.

In order to achieve the above purpose, the utility model provides an integrated exhaust muffler, including: a diffuser, a silencer section, an inlet, and an outlet; the muffler is provided with a plurality of inlets, and the inlets communicate with the diffuser , the diffuser is provided with a silencing section behind the silencing section, and an outlet is provided behind the silencing section; the diffuser is made of a plurality of silencing cylinders, and the silencing cylinder is provided with a silencing hole; the silencing section is provided with There are multiple sound-absorbing panels, and the sound-absorbing micro-holes are arranged in a staggered arrangement on the sound-absorbing panels.

Compared with the prior art, the utility model has the following beneficial effects: when the high-pressure air passes through the diffuser, multiple mufflers are used to reduce the pressure and eliminate noise step by step, without causing damage to the internal components of the muffler; After the noise, it enters the silencer section, and the sound-absorbing micro-holes on the sound-absorbing plate are staggered to be silenced again, which improves the sound-absorbing effect; there are multiple inlets on the silencer, which can be connected to multiple exhaust outlets of medium and high-voltage equipment at the same time. Exhaust gas is noise-reduced and silenced, which saves floor space and reduces enterprise costs.

Detailed ways

The specific embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific embodiments.

Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

As shown in Figure 1-2, the integrated exhaust muffler according to the specific embodiment of the utility model includes: a diffuser 1, a noise reduction section 2, an inlet 3, and an outlet 4; the muffler is provided with a plurality of inlets 3 , can simultaneously connect a plurality of exhaust gas outlets of medium and high pressure equipment, and simultaneously reduce noise and noise of various exhaust gases, save floor space and reduce enterprise costs; the inlet 3 is connected to the diffuser 1, and the rear of the diffuser 1 is set There is a sound-absorbing section 2, and an outlet 4 is arranged behind the sound-absorbing section 2; the diffuser 1 is assembled from a plurality of sound-absorbing cylinders 5, and the sound-absorbing cylinder 5 is provided with a sound-absorbing hole 6, and the high-pressure air flows through the diffuser A plurality of muffler tubes are used to step down the pressure and remove noise step by step, which will not cause damage to the internal components of the muffler; the muffler section 2 is provided with a plurality of muffler plates 7, and sound-absorbing microholes 8 are arranged in a staggered arrangement on the muffler plates 7, and the airflow After being depressurized and noise-removed by the diffuser, it enters the sound-absorbing section, and the sound-absorbing micropores on the sound-absorbing plate are staggered to be silenced again, which improves the sound-absorbing effect.

The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. These descriptions are not intended to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can realize and utilize various exemplary embodiments of the present invention and various Different options and changes.
