Description
Technical field
The present invention relates to a kind of air compressor noise reducing apparatus, particularly relate to a kind of Multifunctional muffling mechanism.
Background technology
Air compressor, being a kind of equipment in order to compress gas, most of air compressors are reciprocating-pistons, rotating vane or rotary screw, it converts the mechanical energy of former dynamic (usually motor) device of gas pressure energy to, is widely used in oil, chemical industry and food manufacturing.
Air compressor is a kind of typical large-sized power plant, and induction noise is that in an important sources, particularly Reciprocting piston compressor of its noise, at the suction inlet of cylinder, sound wave radiates from air inlet with the form of pulsatile change.Prior art applies to deafener many employings impedance complex formula deafener of compressor inlet, to the sound deadening capacity of air inlet noise up to 30 decibels even more than.But in prior art in above impedance complex formula deafener resistive noise elimination part due to by high-frequency air flow pulsatile impact, in gas, the gentle flow distribution of grit is uneven, there is resistive noise elimination part and local damage easily occurs, the problem affecting its resistance sound performance and used life, meanwhile, the noise reduction capability of deafener also awaits further raising.
Summary of the invention
For solving in above-mentioned prior art in above impedance complex formula deafener resistive noise elimination part due to by high-frequency air flow pulsatile impact, in gas, the gentle flow distribution of grit is uneven, there is resistive noise elimination part and local damage easily occurs, the problem affecting its resistance sound performance and used life, problem with the noise reduction capability of deafener also awaits further raising, the invention provides a kind of Multifunctional muffling mechanism.
For the problems referred to above, the present invention solves problem by the following technical programs: a kind of Multifunctional muffling mechanism, including the lower house being tubbiness, the beginning end of lower house is fixedly connected with upper cover, upper cover and lower house surround silencing cavity, silencing cavity is provided with resistive noise elimination part, upper cover or lower house are additionally provided with the gas outlet communicated with silencing cavity and air inlet, also include into tubular and sidewall is provided with the inner core of multiple through hole, one end of inner core is fixed on the bottom of lower house, described resistive noise elimination part includes multiple muffling bucket, described muffling bucket is the tubbiness of lower ending opening, its side is provided with and a plurality of is parallel to its axial bar shaped rib, the left and right sides of bar shaped rib has been fixedly connected with resistive sound-absorbing material, and the resistive sound-absorbing material between adjacent two bar shaped ribs is formed towards the internal lip protruded of muffling bucket, the bottom of lower house is additionally provided with the muffling bucket interface that quantity is equal with muffling bucket quantity, each muffling bucket becomes threaded or bolt to be connected respectively with a muffling bucket interface, and gas outlet is communicated with the inner chamber of muffling bucket by muffling bucket interface, air inlet is positioned on the sidewall of lower house, air inlet is arranged on the sidewall of lower house, and air inlet is tangent with the internal face of lower house with the gas flow direction of lower house joint at it, the bottom outside of lower house is additionally provided with laying dust bucket, described laying dust bucket is between inner core and lower house sidewall.
A resistant noise-reducing device is formed with the silencing cavity formed between upper-lower casing and upper cover；Resistive sound-absorbing material between adjacent two bar shaped ribs is formed towards the internal circulation passage that lip is air-flow entrance muffling bucket protruded of muffling bucket, acoustic energy is converted into thermal energy consumption when gas flows through and falls by the friction of gas and viscosity resistance by resistive sound-absorbing material, the resistive sound-absorbing material arranged adopts porous and the acoustic absorption material ganged up, such as foam plastics, paper slip etc..In resistive noise elimination part, the structure of multiple muffling buckets is arranged above, compared to existing, single muffling bucket is set in silencing cavity, in the silencing cavity of same volume, it is easy to obtain bigger muffling bucket lateralarea, when making gas flow through the present invention, it is good that the silencing cavity centering high frequency noise of unit volume has better acoustically effective；In muffling bucket, circulation passage is the setting of lip shape simultaneously, and the aperture that lip is opened to both sides when air-flow increases becomes big automatically, advantageously reduces the gas of muffling bucket by resistance, is conducive to increasing the maximum gas handling capacity of the present invention；The inner core arranged and the structural relation of lower house make air be introduced in the gap between lower house and inner core by air inlet, air is flow to resistive noise elimination part by the through hole on inner core again, in arrangement above, inner core is similar to the scattered type acoustic filter of through hole resistance, is so more beneficial for the erasure effect of the present invention；Above air inlet is the setting of position relationship on lower house, make the air being entered in lower house by air inlet first can form spiral wind in the gap between lower house sidewall and inner core, so, grit in spiral wind is with flow rotation, grit once with lower house sidewall contact, just lose inertia force under the gravity of self along lower house sidewall fall enter laying dust bucket.
Further technical scheme is:
Described laying dust bucket is the integrated tubular structure of quality of rubber materials, and its upper end and lower house are fixing to be connected, and the lower end of laying dust bucket is flat port and both sides are closed up, and the upper end of laying dust bucket is flat opening or circular open, and the deformation between laying dust bucket two ends smoothly transits.
The version of above laying dust bucket, the space between laying dust bucket two ends is collected for dust, and namely its upper end communicates with silencing cavity, and one container of formation is closed up in lower end；The setting that the deformation between two ends smoothly transits is closed up in its lower end simultaneously so that compressor service personnel only need to apply in pressure to lower end flat port width, and the flat port of lower end just expansible, for dust removing from laying dust bucket；And when the present invention works, owing to it is external pressure vessel, so can ensure that the flat port of lower end is always and close up state.
The top of described muffling bucket is provided with internal thread through hole, the connection screw rod becoming with it threaded it is provided with in described internal thread through hole, the upper and lower side connecting screw rod is respectively relative to the upper and lower side protrusion of muffling bucket, connecting of muffling bucket top outer is provided with on screw rod and is connected the nut that screw rod becomes threaded, described muffling bucket interface is run through the cavernous structure bottom lower house, and in cavernous structure, it is provided with the rib that two ends are connected with its inwall, being provided with connection screw hole on rib, the lower end connecting screw rod becomes threaded with being connected screw hole.
The muffling bucket simple in construction of above version, connect screw rod with after the respective screw-threaded engagement being connected screw hole, being fastenedly connected of muffling bucket and lower house is realized by rotary nut, adopt and realize, by connection screw rod, the connected mode that muffling bucket is connected with lower house, it is easy to be set to muffling bucket remove connect screw rod and nut, remainder all adopts the design of nonmetallic materials, and muffling bucket itself belongs to consumable accessory, so, muffling bucket is damaging or beyond after life cycle, connect screw rod and nut can be separated easily from muffling bucket, it is easy to following cycle utilize, advantageously reduce the use cost of the present invention.
