Embodiment

[0019] refer to Figure 1 to Figure 4 , this embodiment provides a simple foam aluminum muffler, including a hollow cylindrical shell 1, one end of the cylindrical shell 1 is provided with a muffler inlet 11, the other end is provided with a muffler outlet 12, the cylindrical shell 1 is a steel shell, the muffler inlet 11 and The muffler outlet 12 is a circular hole structure coaxial with the cylindrical shell 1. The cylindrical shell 1 is provided with a perforated pipe 2 and two foamed aluminum plates 3. The closed-cell foamed aluminum material prepared by the melt foaming method is made, and the closed-cell foamed aluminum material is perforated to form a connected channel in the foamed aluminum disc. The two foamed aluminum plates 3 are both perpendicular to the axis of the cylindrical shell 1. And the two foamed aluminum plates 3 are closed and fixed with the inner wall of the cylindrical shell 1, the perforated tube 2 is coaxially arranged with the cylindrical shell 1, t...

Abstract

The invention provides a simple foamed aluminum silencer. The simple foamed aluminum silencer comprises a hollow cylindrical housing. A silencer inlet is formed in one end of the cylindrical housing, and a silencer outlet is formed in the other end of the cylindrical housing. A perforated pipe and two foamed aluminum plates are arranged in the cylindrical housing. The foamed aluminum plates are provided with holes and are both perpendicular to the axis of the cylindrical housing. The two foamed aluminum plates are fixed to the inner wall of the cylindrical housing in a sealed mode. The perforated pipe and the cylindrical housing are coaxially arranged. The two ends of the perforated pipe penetrate through the two foamed aluminum plates respectively. Silencing holes are formed in the portion, between the two foamed aluminum plates, of the perforated pipe. The simple foamed aluminum silencer aims to solve the problem that existing silencer materials can cause environment pollution and endanger human health, are prone to moisture absorption and weathering, and are short in service life and poor in effect. The invention belongs to the technical field of silencers.

Description

technical field [0001] The invention relates to a muffler which uses an open-cell foamed aluminum hollow circular plate and a perforated pipe as an internal muffler structure, and belongs to the technical field of mufflers. Background technique [0002] Traditional mufflers often use solid and perforated steel plates as the muffler structure or use porous resistive muffler materials such as glass wool and rock wool to eliminate noise. It does not absorb sound, mainly through the back and forth reflection of the sound wave and the viscosity of the gas to attenuate the sound wave. Resistive sound-absorbing materials are easy to cause environmental pollution, endanger human health, and bring problems such as moisture absorption, easy weathering, and short life. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a simple foam aluminum muffler to solve the problems that the existing muffler materials are easy to cause environmental pollution, ...
