Abstract

The invention belongs to the technical field of blowpipe silencers, and particularly relates to an efficient blowpipe silencer which comprises a shell, one end of the shell is connected with an air inlet pipe, the other end of the shell is connected with an air outlet pipe, a plurality of silencing branch pipes and a plurality of limiting pieces are arranged in the shell, and the two ends of the silencing branch pipes penetrate through the limiting pieces respectively and are connected with the air inlet pipe and the air outlet pipe through connecting rods. The silencing branch pipe is of a bent structure, the limiting piece is fixed to the shell, and the silencer is connected with external air charging equipment through a flange. The defects of an existing silencing pipe are overcome, airflow is refined in a branch pipe guiding mode, the silencing and damping effects are achieved, meanwhile, the stability of the branch pipes is guaranteed through cooperation with the limiting pieces, and the silencing and exhausting effects are improved while the structural stability is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of blowpipe mufflers, and in particular relates to a high-efficiency blowpipe muffler. Background technique [0002] The blowpipe muffler is a commonly used component in the current pipeline process, and it also plays a key role in the internal acoustic treatment. The blowpipe muffler not only needs to meet the requirements of the highest flow rate, the smallest resistance, and the largest momentum of the steam blowpipe, but also needs to reduce pressure and throttle. , Expansion, and frequency-shift noise reduction technology are used as means to reduce noise. The expression of the inner diameter of the pipe of the current blowpipe muffler will form a certain internal echo during use, and even produce a certain resonance, so that the effect of complete noise reduction cannot be achieved. Contents of the invention [0003] Aiming at the problems in the prior art, the present invention provides a high-effi...
