Abstract

The invention discloses a combination type small-hole impeller compound silencer. The combination type small-hole impeller compound silencer comprises a sleeve and an inner tube disposed in the sleeve. The two ends of the inner tube are each in sealed connection with the sleeve through one sealing head, each sealing head is provided with a water injection hole and an exhaust hole for connecting the outside with a sealing chamber formed between the inner tube and the sleeve; the inner tube is formed by connecting multiple segments of inside cylinders; adjacent ends of the multiple segments of inside cylinders are each provided with a semicircular shell; a circular housing composed of adjacent semicircular shells is internally provided with a circular impeller; the semicircular blade of each impeller is provided with a small hole, and the diameters of the small holes arranged in the semicircular blades are different; and one end of the rotation shaft of each impeller extends to the sealing chamber, and a flabellum is fixed at the end of the rotation shaft of each impeller. According to the invention, through rotation of the impellers, the diameters of the small holes of the blades are different, and broadening noise frequency bands are correspondingly eliminated.

Description

technical field [0001] The invention relates to a muffler, in particular to a composite muffler with small hole impellers. Background technique [0002] With the rapid development of economic construction and the improvement of living conditions, people have higher and higher requirements for living and working environments, and a quiet living and working environment is the focus of pursuit. Noise is a common pollution factor in industry. Industrial noise is mainly generated by various equipment in the enterprise. Noise can cause hearing loss, difficulty concentrating, unresponsiveness, and easy fatigue, which not only affects the work speed, but also reduces the quality of work. If the noise level exceeds 85dB, it will harm people's nervous system, cardiovascular system, digestive system and endocrine system, resulting in diseases such as neurasthenia and high blood pressure. Therefore, noise reduction and noise prevention must be considered when designing products. Co...
