Problems solved by technology

[0003] In today's society, noise pollution is becoming more and more serious. The muffler can significantly reduce various industrial noises. However, the existing muffler is large in size, and it is inconvenient to install and disassemble the machine at the same time.
In addition, the main body of the muffler is still mainly made of metal such as steel, which is not only heavy, inconvenient to install, but also has insufficient corrosion resistance

Abstract

The present invention relates to a muffler, the muffler includes a hollow cylindrical muffler net and a casing wrapping the muffler net, muffler cotton is arranged between the casing and the muffler net, the casing, the muffler cotton and the muffler net are arranged in parallel, the muffler further comprises a mounting member arranged on two ends of the muffler net, a mounting through hole is arranged in the middle part of the mounting member, the upper end face of the mounting member is provided with a cutting face, muffler net holes are arranged on the middle part of the lower end face of the mounting member, the muffler net holes and the mounting through hole can be coaxially arranged, the muffler net can be clamped and embedded by the muffler net holes, a casing groove capable of clamping and embedding the casing is dug on the outer side face of the mounting member, and the casing is made of a composite material which comprises, 40-50wt% of epoxy; 5-20wt% of alkali-free glass fiber; 15-30wt% of mineral fiber; 0.5-5wt% of a flow modifier; 1-3wt% of a heat modifier; 3-5wt% of a compatibilizer; 0.3-0.5wt% of a primary antioxidant; 0.3-0.5wt% of a secondary antioxidant and 1-3wt% of a processing aid. The muffler is simple in structure, the casing is made of the composite material, the mounting member is made of a reasonable compatibility material, and the use efficiency and the service life of the entire blast blower can be further improved.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a muffler. Background technique [0002] A muffler ((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] In today's society, noise pollution is becoming more and more serious, and mufflers can significantly reduce various industrial noises, but the existing mufflers are large in size, and it is extremely inconvenient to install and disassemble the machine at the same time. In addition, the main body of the muffler is still mainly made of metal such as steel, which is not only heavy, inconvenient to install, but also has insuff...
