Problems solved by technology

When the fan is running, it will generate a lot of noise due to the rotation of the motor and the agitation of the air. It is estimated that the noise generated by a fan with a diameter of 800mm can reach more than 80dB during normal operation, and multiple fans are usually used in linkage in buildings. further increases the noise
At present, the measures for reducing fan noise still have defects such as complex structure, inconvenient use, ineffective effect, and non-disassembly and cleaning, which have caused great pressure on environmental protection.

Abstract

The invention discloses a zigzag noise reduction device, which comprises a fixed cylinder, a positioning ring, and noise reduction cotton; The cylinder includes two semi-circular bodies with a semi-circular cross-section; the two semi-circular bodies are docked to form a cylindrical structure; the inner sides of the two semi-circular bodies are provided with internal threads that match each other; The positioning ring is provided with two, and the outside of the positioning ring is provided with an external thread; the positioning ring is installed on the two ends of the semi-circular body through the external thread and the internal thread; the sound-absorbing cotton is installed in the sound-absorbing cavity; The sound-absorbing cotton has a zigzag structure; the two ends of the sound-absorbing cotton abut against the inner sides of the positioning rings at both ends of the fixed cylinder. The invention has good noise reduction effect and is convenient to disassemble and clean.

Description

technical field [0001] The present invention relates to a sawtooth muffler. Background technique [0002] The fan is a gas compression and gas conveying machine. When the fan is running, the rotating mechanical energy is converted into gas pressure energy and kinetic energy and the gas is transported out. In buildings, fans are widely used for ventilation and heat exchange. The normal operation of fans is related to the energy consumption of transmission and distribution of the system, and is a very critical part of building energy conservation. When the fan is running, due to the rotation of the motor and the stirring of the air, it will generate a lot of noise. It is estimated that the noise generated by a fan with a diameter of 800mm can reach more than 80dB during normal operation. further increase the noise. At present, the measures for reducing fan noise still have defects such as complex structure, inconvenient use, inconspicuous effects, and inability to disassembl...
