The invention discloses a built-in type draught fan silencer. The built-in type draught fan silencer comprises an outer straight barrel and an inner straight barrel, micro-holes are densely distributed in the inner straight barrel, sound absorption cotton is arranged between the outer straight barrel and the inner straight barrel, and annular sealing plates are arranged at the two ends of the outer straight barrel and the two ends of the inner straight barrel for fixation; an air inlet barrel is concentrically arranged in an inner hole of the annular sealing plate at one end of the outer straight barrel, the front end of the air inlet barrel extends out of the outer straight barrel, and a plurality of rotation devices are arranged on the outer circle of the front end of the air inlet barrel; and each rotation device is provided with a threaded rod, and a lifting supporting sleeve is arranged at the end of each threaded rod. By means of the above manner, according to the built-in type draught fan silencer, the lifting supporting sleeves can abut against the inner wall of a draught fan pipe, the outer straight barrel is fixed into the draught fan pipe for air flow noise reduction work, leakage of air flow is effectively avoided, the structure is simple, and mounting and demounting are relatively convenient.
Description
technical field [0001] The invention relates to the field of mufflers, in particular to a built-in fan muffler. Background technique [0002] Fans are widely used for ventilation, heat dissipation, gas compression and material transportation, and are equipped in many factories and commercial buildings. [0003] The work of the fan requires high-speed operation in order to drive the high-speed flow of gas to carry out the corresponding work. When the air is in and exhaust, the wind noise generated by the high-speed air flow is relatively large, and corresponding noise reduction treatment is required to reduce noise pollution. Ordinary mufflers are usually connected in series on the pipeline, and the sealing performance needs to be considered when connecting. The structure is complicated and the construction is difficult, so it needs to be improved. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a built-in fan s...
