A muffler assembly for a double-exhaust cylinder

Abstract

The invention discloses a silencer assembly for a double-exhaust cylinder. The silencer assembly for the double-exhaust cylinder has good heat insulation effect and good sound insulation effect. The silencer assembly for the double-exhaust cylinder comprises a first exhaust cylinder pipe, a second exhaust cylinder pipe, a heat insulation board and a silencing box, a short gas intake pipe, a long gas intake pipe and a multi-hole pipe are arranged in the silencing box, the silencing box is divided into an upper layer, a middle layer and a lower layer, the inlet of the short gas intake pipe is connected with the first exhaust cylinder pipe, the outlet of the short gas intake pipe is located in the upper layer, the inlet of the long gas intake pipe is connected with the second exhaust cylinder pipe while the outlet is located in the lower layer, the multi-hole pipe is communicated with the upper layer, middle layer and lower layer, the heat insulation board is arranged at the outer side of the silencing box and provided with a tail pipe, the middle layer of the silencing box is provided with a gas outlet, and the gas outlet is connected with the tail pipe. The silencer assembly for the double-exhaust cylinder has beneficial effects that one multi-hole pipe can eliminate noise for two times, the sound insulation effect is improved, the heat insulation effect is improved, the efficiency of the conversion between the sound energy and heat energy is improved, the structure is simple, the mounting and dismounting are facilitated, the service life is improved, and the device stability and reliability are improved.

Description

technical field [0001] The invention relates to the technical field related to mufflers, in particular to a muffler assembly for a double-exhaust cylinder. Background technique [0002] The muffler is a device that allows airflow to pass through, but can prevent or reduce sound transmission, and is an important measure to eliminate aerodynamic noise. The muffler can block the propagation of sound waves and allow airflow to pass through, which is an effective tool for noise control. There are many types of mufflers, but the muffler mechanism can be divided into six main types, namely resistive muffler, resistive muffler, impedance composite muffler, micro-perforated plate muffler, small hole muffler and active muffler. Most of the existing mufflers adopt the principle of impedance composite noise reduction. Due to complex structure, heavy weight, high-temperature oxidized sound-absorbing filler, high-speed airflow impacting sound-absorbing filler, water vapor permeating sou...

Problems solved by technology

The disadvantage of this utility model is that the sound-insulating layer and the sound-absorbing layer can only be used for sound-absorbing and cannot effectively insulate heat, and because the working environment is harsh, the edges of the sound-insulating layer and the sound-absorbing layer are exposed, and it is very easy to enter the water in the use environment. Forming an acid-base environment with various dusts will cause damage to the sound insulation layer and sound absorption layer, affecting its life and sound insulation effect
