Abstract
A draught fan silencer comprises an outer wall, an inner wall, a sound insulation packing material, a supporting base, silencing interlayers, resistance type silencing sheets, lifting rings and reinforcing ribs. The supporting base is arranged at the lower end of the outer wall. The silencing interlayers are connected with the inner wall and internally provided with the resistance type silencing sheets. The lifting rings are arranged at the upper end of the outer wall. The outer wall is made of stainless steel. The sound insulation packing material is arranged between the outer wall and the inner wall. The multiple silencing interlayers are arranged in parallel at equal intervals. The reinforcing ribs are arranged on the outer wall. The draught fan silencer has the beneficial effects that air power noise generated by draught fans of various types is lowered, the silencing amount is large, the silencing band width is high, resistance loss is small, and the structure is simple, installation is convenient; the strength of a shell is enhanced through the reinforcing ribs, the overall strength of the product is enhanced, and the silencer is prevented from being scattered in the transportation or installation process.
Description
Technical field
The present invention relates to a kind of fans silencer.
Background technique
Blower fan is a kind of general machinery equipment, and its using scope is very wide, and the production of the every profession and trades such as electric power, mine, machinery, metallurgy, chemical industry all be unable to do without blower fan.The noise of the on-stream generation of blower fan usually becomes the misfortune source affecting workers ' health and interference environment.The particularly blower fan in contiguous living area, the air power noise of its intake grill and the radiation of exhaust outlet institute, the principal element of befouling environment especially, forming public hazards, is Industry Branch in recent years, one of main object that noise control pollutes, industrial blower fan, belongs to the equipment of running continuously.International Organization for Standardization is≤90 decibels to the noise standard of this kind equipment defined, the new standard of China is identical therewith, the foundation that this Ye Shi industrial enterprise continuous noise is up to standard, but when not adopting noise countermeasure, the noise that blower fan inlets and putlets of ventilation penetrates to environment can reach 110 ~ 120 decibels, greatly exceed requirement up to standard, fans silencer (Fansilencer), identical with the form of exhaust duct silencing apparatus and forced-and-induced draft fan baffler, all adopt centering, high-frequency wideband characteristic has the resistive absorbing sound and lowering noise principle of better effects, to low, the reactive muffling flat principle of good result and micropunch silencing apparatus and impedance composite muffler is had when intermediate frequency and pulse characteristic, although be applied on blower fan at more existing silencing apparatuss on the market, but the complex structure of these silencing apparatuss, assemble cumbersome.
Summary of the invention
Object of the present invention is just to provide a kind of fans silencer to solve the problem.
The present invention is achieved through the following technical solutions above-mentioned purpose: a kind of fans silencer, comprise outer wall, inwall, sound insulation packing material, base for supporting, noise elimination interlayer, resistive anechoic sheet, suspension ring and stiffening rib, described outer wall lower end is provided with base for supporting, described noise elimination interlayer is connected with inwall, described noise elimination interlayer inside is provided with resistive anechoic sheet, and described suspension ring are arranged on the upper end of outer wall.
Further, described outer wall adopts stainless steel material to make.
Further, sound insulation packing material is provided with between described outer wall and inwall.
Further, described noise reduction interlayer is provided with multiple, and noise reduction interlayer be arranged in parallel and each other apart from equal.
Further, described outer wall is provided with stiffening rib.
Beneficial effect of the present invention is: this apparatus structure is simple, enter by the anechoic sheet of both sides inner during air sound wave, the sound-absorbing material be filled in anechoic sheet absorbs needs decay, be provided with sound insulation packing material between inner and outer wall simultaneously, to reach the object reducing noise, the air power noise that this invention produces for reducing various blower fan, has the features such as sound deadening capacity is large, anechoic frequency bandwidth, drag losses are little, easy for installation.Can be widely used in the industries such as power station, petrochemical industry, mine, metallurgy, building, and stiffening rib is arranged in the outer wall of housing, is added the intensity of housing by stiffening rib, the bulk strength of product is obtained and strengthens, avoid falling apart in transport or installation process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, outer wall, 2, inwall, 3, sound insulation packing material, 4, base for supporting, 5, noise elimination interlayer, 6, resistive anechoic sheet, 7, suspension ring, 8, stiffening rib.
