Intake silencer for acoustic enclosure of compressor unit

Abstract

The invention relates to an intake silencer for an acoustic enclosure of a compressor unit. The intake silencer is mainly composed of an intake silencer box body, a plurality of broken line type intake silencing channels and a right-angle triangular prism sound absorption structures, wherein the intake silencer box body is of a quadrangular prism structure with trapezoidal side plates, and the broken line type intake silencing channels formed by arranging the right-angle triangular prism sound absorption structures side by side in a broken line form are arranged in the intake silencer box body; and each right-angle triangular prism sound absorption structure is composed of a right-angle triangular prism sound absorption structure inclined face, a right-angle triangular prism sound absorption structure long right-angle face, a right-angle triangular prism sound absorption structure short right-angle face and an unequal-thickness cavity structure. The intake silencer has the advantages of being simple in structure, accelerating the intake speed, increasing the effective ventilation quantity, effectively controlling the noise transmission path, remarkably improving the noise reduction effect and the like.

Description

Technical field: [0001] The invention relates to the technical field of ventilation and noise reduction of compressor units, in particular to an intake muffler used for a sound insulation cover of a compressor unit. Background technique: [0002] With the rapid development of industrialized society, the phenomenon of industrial noise pollution is becoming more and more common. Noise not only reduces people's work efficiency, damages people's nervous system, but also has increasingly serious harm to human living environment. One of the three major environmental pollution. At present, air intake mufflers at home and abroad are usually used in traditional industrial plants, various mechanical equipment and other industrial occasions for ventilation and noise reduction technology, but they often only meet the needs of ventilation volume, and do not meet the factory boundary noise standard (reaching the national standard GB12348- Class II requirements in 2008) not higher than 60...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to not only improve the effective ventilation volume, solve the problem of ventilation and heat dissipation requirements, but also effectively control the noise transmission path, and meet the noise reduction requirements of the industrial factory boundary. silencer
