Silencer for jet type blower
专利汇可以提供Silencer for jet type blower专利检索，专利查询，专利分析的服务。并且PURPOSE: To facilitate exchange of sound absorbing materials and to suppress the increase of the generation of noise due to contamination by a method wherein a sound absorbing material for a silencer is formed in a small regular or irregular blockform shape, and an exchange port for the sound absorbing material is formed, where necessary.
CONSTITUTION: Blockform sound absorbing materials 7b are arranged between a steel plate 10 and a perforated steel plate 8 of an outer cylinder 5 of a body casing 3 and a silencer casing 4 of a jet type blower. The shape of the sound absorbing material 7b may be a small regular or irregular blockform shape, and when the sound absorbing materials each having at least a maximum size being approximately equal to the size of a spherical shape being lower than a half of a gap between the steel plate 10 and the perforated steel plate 8 are arranged, unevenness in the gap therebetween is not produced, and unevenness in sound isolating performance is reduced. The use of the blockform sound absorbing material 7b scrapes out the contaminated sound absorbing materials 7b through a partial opening part 15 for exchange, and inserts the new sound absorbing materials 7b. This constitution easily restores sound absorbing performance.
