Abstract
The invention relates to a fan silencer for a furnace. The fan silencer consists of an outer silencer, an inner silencer, a fan connecting plate, a cylindrical silencing plate, an inner silencing plate, an outer silencing plate, sound wave shock absorbers and an air inlet flange, wherein the silencer is of a cylindrical structure, the outer silencing plate and the inner silencing plate are respectively and uniformly distributed with a plurality of silencing holes, the friction of the sound energy inside the pore of each silencing hole produces the heat energy which can be automatically consumed, the sound wave of the silencer is weakened, the purpose for eliminating the medium-high-frequency noise produced in the work of a fan can be realized, the sound wave shock absorbers are respectively arranged inside the outer silencer and the inner silencer, a shock absorption material is respectively arranged inside each sound wave shock wave absorber, a purpose for lowering the air power noise can be realized through the sound absorption function of the sound wave shock absorption materials, the sound wave shock absorption materials can also effectively prevent mosquitoes and granular substances from entering the silencer, and the damage to the fan caused by the mosquitoes and the granular substances can be avoided. The fan silencer for the furnace has the characteristics of simplicity in structure, reasonability in design, good silencing effect, energy conservation and lower noise.
Description
Technical field
The present invention relates to a kind of cremation machine accessory, specifically a kind of stove muffler for fan.
Background technique
At present, China's employed fan noise of funeral parlor cremation machine is very large, although some blower fans have adopted baffler, effect is all not obvious, does not satisfy the requirement of " industrial and mining enterprise's noise sanitary standard ", and the person and production have all been caused harm.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, reasonable in design, soundproof effect is good, the stove muffler for fan of energy-saving and noise-reducing.
The present invention solves the problems of the technologies described above the technological scheme that adopts: a kind of stove muffler for fan, be provided with outer baffler, fixing bolt, inside and outside baffler connecting plate, interior baffler, the blower fan connecting plate, the tubular acoustical panel, interior acoustical panel, outer acoustical panel, bloop, the sound wave vibration damper, the 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, the blower fan connecting plate is fixed on the intake grill flange, the inner 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, outer baffler links to each other with interior baffler with inside and outside baffler connecting plate by fixing bolt, 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 present invention is owing to adopting said structure, acoustic energy rubs in the hole of bloop and produces heat energy and automatically consume, the sound wave of baffler is weakened, reach the purpose of the medium-high frequency noise that produces when eliminating blower fan work, utilize the sound absorption function of the efficient vibration-absorptive 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 entering baffler inside simultaneously, thereby further avoids blower fan is caused damage.Have simple in structure, reasonable in design, the characteristics such as soundproof effect is good, energy-saving and noise-reducing.
