Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of array type silencer, and it can increase absorbed noise content, improves soundproof effect.
For solving the problems of the technologies described above, the technical solution of the utility model array type silencer is:
Comprise framework, framework internal fixtion is provided with multiple noise elimination post, and multiple noise elimination post is the arrangement in array-type in framework; Described noise elimination post comprises air guide sleeve, and the cover body cross section of air guide sleeve is rectangle or square; The faceshield side wall of air guide sleeve is distributed with multiple perforation; The two ends of described air guide sleeve form streamlined end socket; Sound-absorbing material is filled with in described air guide sleeve.
The faceshield side wall outer surface of described air guide sleeve is formed with many arc-shaped concaves extended vertically; Or the faceshield side wall of air guide sleeve is waveform face.
The adjacent cover body sidewall of described air guide sleeve is fixedly connected with; The formation right angle, end of one of them faceshield side wall, the end of another faceshield side wall forms right angle type groove; The right angle of faceshield side wall inserts in the right angle type groove of adjacent cover body sidewall, realizes being fixedly connected with of two faceshield side walls.
Described end socket is fixedly installed link, link offers screw, for being fixedly connected with framework.
The utility model also provides a kind of noise elimination post, and its technical solution is:
Comprise air guide sleeve, the cover body cross section of air guide sleeve is rectangle or square; The faceshield side wall of air guide sleeve is distributed with multiple perforation; The two ends of described air guide sleeve form streamlined end socket; Sound-absorbing material is filled with in described air guide sleeve.
The faceshield side wall outer surface of described air guide sleeve is formed with many arc-shaped concaves extended vertically; Or the faceshield side wall of air guide sleeve is waveform face.
The adjacent cover body sidewall of described air guide sleeve is fixedly connected with; The formation right angle, end of one of them faceshield side wall, the end of another faceshield side wall forms right angle type groove; The right angle of faceshield side wall inserts in the right angle type groove of adjacent cover body sidewall, realizes being fixedly connected with of two faceshield side walls.
The technique effect that the utility model can reach is:
The utility model is formed with many concave surfaces extended vertically at the faceshield side wall outer surface of noise elimination post, or adopt corrugated faceshield side wall, to increase the surface of contact between the cover body of noise elimination post and air-flow, when the gap of air-flow between adjacent two noise elimination posts, the noise content that noise elimination post can absorb also becomes large thereupon.
