The invention discloses an air blower outlet pipeline type silencer. The air blower outlet pipeline type silencer is characterized in that the air blower outlet pipeline type silencer comprises a dense hole diffusion inner sieve tube, a dense hole diffusion outer sieve tube, an outer layer air guide and sound insulation tube and a dense hole partition plate, one end of the dense hole diffusion inner sieve tube and one end of the dense hole diffusion outer sieve tube are respectively provided with a flange, the right end of the dense hole diffusion inner sieve tube is blocked by a semispherical dense hole sieve plate to form a blind tube shape, the dense hole partition plate is arranged in the dense hole diffusion inner sieve tube, the dense hole diffusion outer sieve tube is of a through type, the opening of the left end of the dense hole diffusion outer sieve tube and the flange of the dense hole diffusion inner sieve tube are welded together, the two ends of the outer layer air guide and sound insulation tube are welded to the outer circles of the two ends of the dense hole diffusion outer sieve tube through arc-shaped connectors, and the end, provided with the semispherical dense hole sieve plate, of the dense hole diffusion inner sieve tube is inserted into the end, not provided with the flange, of the outer layer air guide and sound insulation tube, and is connected with a guide groove in the outer wall of the dense hole diffusion inner sieve tube through a supporting rib which is arranged on the inner wall of the dense hole diffusion outer sieve tube.
Description
technical field [0001] The invention relates to a muffler, in particular to a blower outlet pipeline type muffler. Background technique [0002] The blower is a common equipment for air compression and transportation, and is widely used in various industries such as industrial production and municipal sewage treatment. During the use of the blower, there will be a lot of noise in the outlet of the fan and the subsequent pipeline. In order to reduce the noise, noise reduction equipment is usually installed on the outlet pipeline of the blower. The muffler is a device that prevents sound transmission and allows airflow to pass through. Reduce the noise generated by the fan. The noise reduction effect of the existing blower muffler is not ideal, and the noise value after the noise reduction is still difficult to meet the requirements of the noise pollution control standard, and it is easy to cause damage to the operator's hearing and cause adverse effects on the surrounding en...
