Abstract
The present invention discloses a kind of sound arrester for equipment and conveyer belt.For a sound arrester for equipment and conveyer belt, imported and exported by sound insulation enclosure, sound insulation absorbent lined barrier, conveyer belt, sound insulation holds court from behind a screen and form.Sound insulation enclosure interior separation is three regions by described sound insulation absorbent lined barrier, and middle part is main noise source equipment region, and two limits are conveyer belt region; Described conveyer belt is imported and exported and is arranged on the position of conveyer belt through sound insulation enclosure, sound insulation absorbent lined barrier, and arrange parallel sound insulation sound absorption construction along belt direction, opening specification is greater than the maximum specification of convey materials.The structure that described sound insulation enclosure is insulated against sound outward by interior sound absorption forms, and is arranged on outside main noise source and part conveyer belt, and sound insulation enclosure is provided with sound insulation access door, daylighting observation port.Not only there is higher sound insulation factor, and easy to use, safeguard simple.
Description
Technical field
The present invention relates to a kind of noise control technique field, a kind of sound arrester structure for equipment and conveyer belt that especially effectively can intercept noise transmission.
Background technology
Current, the production equipment noise that noise has become a kind of main environment pollution, particularly industrial enterprise is very large to producers' health effect, and noise is a kind of main occupational disease.Strong noise equipment mainly takes the mode of equipment sound insulation enclosure to be intercepted at present, but, because equipment component brings conveying production material by conveying, equipment sound insulation enclosure cannot be accomplished to close completely, cause the impact of noise of equipment to be difficult to eliminate, the workshop condition noise of numerous industrial enterprise does not often meet the requirement of " industrial enterprise's noise sanitary standard ".
So far, the sound insulation and noise reducing with the strong noise equipment of conveyer belt is the difficult point in noise reduction engineering.For step convey materials, there is the mode taking induction electric to be elevated Sound isolation curtain.But, there is the problem high to the technical requirement of induction electric jacking equipment, if there is fault, just there is certain risk.Meanwhile, for the convey materials of continous way, still there is no ripe public technology.
Summary of the invention
In order to overcome the deficiency of existing equipment sound insulation enclosure, the invention provides a kind of sound arrester structure for equipment and conveyer belt, this kind not only has higher sound insulation factor for the sound arrester of equipment and conveyer belt, and easy to use, safeguards simple.
The technical solution adopted for the present invention to solve the technical problems is: a kind of sound arrester for equipment and conveyer belt, is imported and exported, sound insulation holds court from behind a screen and form by sound insulation enclosure, sound insulation absorbent lined barrier, conveyer belt.Sound insulation enclosure interior separation is three regions by described sound insulation absorbent lined barrier, and middle part is main noise source equipment region, and two limits are conveyer belt region; Described conveyer belt is imported and exported and is arranged on the position of conveyer belt through sound insulation enclosure, sound insulation absorbent lined barrier, along belt direction, parallel sound insulation sound absorption construction is set, opening specification is greater than the maximum specification of institute's convey materials, be that convey materials can pass through smoothly in order to ensure, not hinder the carrying out of production.
The structure that described sound insulation enclosure is insulated against sound outward by interior sound absorption forms, and is arranged on outside main noise source and part conveyer belt, and sound insulation enclosure is provided with sound insulation access door, daylighting observation port.Described sound insulation is held court from behind a screen and to be made up of transparent soft glass, is arranged on the outer end that conveyer belt is imported and exported, and sound insulation is held court from behind a screen and left the import and export of convey materials between conveyer belt.Described sound insulation absorbent lined barrier is by two sound absorptions, and the structure composition of middle sound insulation, all closes except leaving conveyer belt and importing and exporting, and sound insulation absorbent lined barrier is provided with sound insulation access door, daylighting observation port.
The noise during work of main noise source equipment absorbs through sound absorption construction in main noise source equipment region, the noise weakened is imported and exported by the conveyer belt that noise barrier is arranged and is propagated outward through arranging parallel sound insulation sound absorption construction along belt direction, parallel sound insulation sound absorption construction plays the effect of dissipative muffler, weakened further in communication process, the sound insulation of the outlet of parallel sound insulation sound absorption construction is held court from behind a screen and outlet to be reduced further, narrow outlet and sound insulation enclosure, the conveyer belt region production cross section sudden change expansion that sound insulation absorbent lined barrier is formed, the acoustic energy diffusion of noise, conveyer belt region forms noise elimination breathing space.In breathing space, the acoustic pressure of unit area is multiple/mono-of divergence ratio, thus fully expanded step-down, deceleration, playing effective noise elimination effect to low frequency and part intermediate frequency, have good noise elimination effect to medium-high frequency, is a kind of wide frequency spectrum noise elimination structure.The soundproof effect of noise elimination breathing space is relevant to the several times of the cross-sectional expansion ratio of air outlet, and the divergence ratio several times of the abrupt change of cross-section are larger, and soundproof effect better.
Simultaneously, the noise weakened absorbs through sound absorption construction in conveyer belt region, the noise weakened is imported and exported by the conveyer belt that sound insulation enclosure is arranged and is propagated outward through arranging parallel sound insulation sound absorption construction along belt direction, the sound insulation of the outlet of parallel sound insulation sound absorption construction is held court from behind a screen and outlet to be reduced further, narrow outlet and workshop inner region again production cross section are suddenlyd change and are expanded, the further expansion recedes of acoustic energy of noise, eliminates the harm caused producers effectively.
The invention has the beneficial effects as follows, can meet the sound insulation with conveyer belt apparatus, sound insulation factor is high.
