Abstract

The invention relates to an intake muffler used for a sound insulation cover of a compressor unit, which is mainly composed of an intake muffler box body, a zigzag type intake muffler channel and a right-angled triangular prism sound-absorbing structure. The air intake muffler box body is a quadrangular prism structure with trapezoidal side panels, and inside the box body is a plurality of broken-line air intake and muffler channels formed by arranging side-by-side right-angled triangular prism sound-absorbing structures in the form of broken lines; the right-angled The triangular prism sound-absorbing structure is composed of the inclined surface of the right-angled triangular prism sound-absorbing structure, the long right-angle surface of the right-angle triangular prism sound-absorbing structure, the short right-angle surface of the right-angle triangular prism sound-absorbing structure and the non-equal thickness cavity structure. The invention has the advantages of simple structure, quicker air intake speed, higher effective ventilation volume, effective control of noise transmission paths, significantly improved 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...
