Example Embodiment

[0047] In another embodiment of the present invention, a method for preparing a lattice-type muffler is provided, which is characterized in that it includes the following steps:

[0048] Prepare foamed aluminum plate;

[0049]Cutting the foamed aluminum plate according to the set size and thickness;

[0050] The cut foamed aluminum plates are respectively embedded in the fixed parts of the first frame, the second frame and the third frame, and assembled into a lattice type muffler.

[0051] The step of inlaying the cut foamed aluminum plates into the fixed parts of the first frame, the second frame, and the third frame respectively to form a grid-type muffler may further include: firstly put the first frame in place, and place the foamed The aluminum plates are respectively embedded in the two fixed parts of the first frame, and the upper, lower, left and right parts are respectively connected to the second frame; the foamed aluminum plates are respectively embedded in the th...

Abstract

The invention discloses a grate muffler which comprises a fixing device and foamed aluminum plates. The fixing device further comprises a first frame, a second frame and a third frame, and the foamed aluminum plates are respectively embedded in the first frame, the second frame and the third frame to form the grate muffler. The first frame further comprises a basic part and two fixing parts; the second frame further comprises a basic part and three fixing parts; the third frame further comprises a basic part and four fixing parts; and the fixing parts are used for embedding the foamed aluminum plates. The grate muffler is made from light pure metal foamed aluminum plates, is formed by assembling frames, and has the advantages of easy disassembly and assembly, convenient flushing with water, recycling, no generation of poisonous gases in a fire, no dust pollution, good sound absorption effect and the like.

Description

technical field [0001] The invention relates to the technical field of muffler and its preparation, in particular to a lattice type muffler and its preparation method. Background technique [0002] Mufflers are mainly used for noise reduction in building vents, subway air outlets, factories, ship chimneys and other parts. The muffler is a device that prevents sound transmission and allows airflow to pass through, and is an important measure to eliminate aerodynamic noise. The muffler is installed on the air flow channel of aerodynamic equipment (such as blower, air compressor, boiler exhaust, generator, water pump and other equipment with high exhaust noise) or in the intake and exhaust system to reduce noise. device. [0003] There are many types of mufflers, but in terms of their muffler mechanism, they can be divided into six main types, namely resistive mufflers, resistive mufflers, impedance composite mufflers, micro-perforated plate mufflers, and small hole mufflers....
