Abstract
The utility model relates to an air blower silencer for a stove. The air blower silencer for a stove consists of an external silencer, an internal silencer, an air blower connection plate, a cylindrical silencing plate, an internal silencing plate, an external silencing plate, an acoustic wave shock absorber, air inlet flanges, etc. The silencer structurally is a cylinder. A plurality of silencing holes are evenly distributed on the external silencing plate and the internal silencing plate. Sound energy is rubbed against the apertures of the silencing holes and generates thermal energy and then the energy is automatically consumed, so that sound waves of the silencer are reduced, and thus an aim for eliminating noise with medium-high frequency generated during the operation of the air blower is achieved. The inside of the external silencer and the inside of the internal silencer are provided with sound wave shock absorbers, wherein the inside of the sound wave shock absorber made of shock absorbing material. With the sound absorbing function of the sound wave shock absorbing material, an aim for reducing the noise of aerodynamic force is achieved, and at the same time, the sound wave shock absorbing material can effectively prevent mosquitoes, insets and granular substances from entering into the inside of the silencer, and thus damage to the air blower is prevented. The air blower silencer for a stove has the characteristics of simple structure, reasonable design and good silencing effect, and is energy-saving and noise-reducing.
Description
Technical field
The utility model relates to a kind of cremation machine accessory, and specifically a kind of stove is used the blower fan baffler.
Background technique
At present, China's employed fan noise of funeral parlor cremation machine is very big, though the blower fan that has has adopted baffler, effect is all not obvious, has satisfied not the requirement of " industrial and mining enterprise's noise sanitary standard ", and the person has all been caused harm with producing.
Summary of the invention
The utility model technical problem to be solved is the deficiency that overcomes above-mentioned existing technology, provides a kind of simple in structure, reasonable in design, stove effective, energy-saving and noise-reducing of eliminating the noise to use the blower fan baffler.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of stove is used the blower fan baffler; Be provided with outer baffler, fixing bolt, inside and outside baffler connecting plate, interior baffler, blower fan connecting plate, tubular acoustical panel, interior acoustical panel, outer acoustical panel, bloop, sound wave vibration damper, intake grill flange; It is characterized in that: baffler is combined by outer baffler and interior baffler; All adopt cylinder-like structure, interior baffler is provided with the blower fan connecting plate, and the blower fan connecting plate is fixed on the intake grill flange; The interior circle of interior baffler is provided with the tubular acoustical panel; Interior baffler is provided with interior noise reduction version near the end face of outer baffler one side, and outer baffler links to each other with interior baffler with inside and outside baffler connecting plate through fixing bolt, and the inner side end of outer baffler is provided with outer acoustical panel; Average mark is furnished with many bloops on outer acoustical panel and the interior acoustical panel, and outer baffler and interior baffler inside are equipped with the sound wave vibration damper.
The utility model is owing to adopt said structure; Acoustic energy friction-produced heat energy in the hole of bloop consumes automatically, and the sound wave of baffler is weakened, and reaches the purpose of the medium-high frequency noise that produces when eliminating blower fan work; Utilize the sound absorption function of the efficient damping material in the sound wave vibration damper; Reach the purpose that reduces the aerodynamic force noise, the sound wave vibration damper can prevent effectively that mosquito and particulate material from getting into baffler inside simultaneously, thereby further avoids blower fan is caused damage.Have simple in structure, reasonable in design, characteristics such as noise elimination is effective, energy-saving and noise-reducing.
