Problems solved by technology
[0002] The muffler is a device that can effectively prevent or reduce the outward propagation of sound energy while allowing airflow to pass through. It is mainly used for noise control of the inlet and outlet ducts of mechanical equipment or ventilation ducts. Mufflers are used in blowers. However, the silencer and the diffuser cone in the general blower are independent of each other, so the equipment takes up a lot of space and is inconvenient to arrange

Embodiment Construction
[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.
[0014] Such as figure 1 As shown, a blower diffuser cone muffler disclosed by the present invention combines the diffuser cone and the silencer into one, specifically includes a diffuser cone body 1, and the diffuser cone body 1 has advanced Air outlet 12, air outlet 11 and housing 13, the cross section of the diffuser cone body 1 is trapezoidal, the cross section of the air inlet 12 is smaller than the cross section of the air outlet 11, and the first fixed cylinder 3 is installed on the air inlet 12, so The air outlet 11 is equipped with a second fixed cylinder 2, the housing 13 is provided with an orifice 4, and the distance between the orifice 4 and the housing 13 is 25-30 mm, and the orifice 4 faces the One side of the casing 13 is provided with a 0.1mm plain weave alkali-free g...

The invention discloses a diffusion taper pipe silencer for a blower. The diffusion taper pipe silencer for the blower comprises a diffusion taper pipe body with an air inlet, an air outlet and a shell; the section of the air inlet is smaller than the section of the air outlet; the air inlet is provided with a first fixing drum; the air outlet is provided with a second fixing drum; a perforated plate is arranged in the shell; a partition plate is arranged between the perforated plate and the shell; the partition plate divides the space between the perforated plate and the shell into upper and lower parts; the silencer is arranged in the upper and lower parts. The diffusion taper pipe for the blower is simple and novel in structure and convenient to mount, and the diffusion taper pipe and the silencer are integrated, so diffusion is realized, the gas flow speed is reduced, the noise caused by high-speed air flows is absorbed, the manufacturing cost and space are saved and the structure of the blower is enabled to be more compact.
Description
technical field [0001] The invention relates to the field of blower mufflers, in particular to a blower diffuser conical tube muffler combined with sound attenuation and diffuser cone tubes. Background technique [0002] The muffler is a device that can effectively prevent or reduce the outward propagation of sound energy while allowing airflow to pass through. It is mainly used for noise control of the inlet and outlet ducts of mechanical equipment or ventilation ducts. Mufflers are used in blowers. However, in general blowers, the muffler and the diffuser cone are independent of each other, so the equipment takes up a lot of space and is inconvenient to arrange. Contents of the invention [0003] Purpose of the invention: In order to solve the deficiencies of the prior art, the present invention combines the diffuser cone tube and the silencer to provide a diffuser cone tube silencer that can diffuse pressure and silence sound. [0004] The object of the present inv...
