On circular air pipe 13, be arranged with dedusting body 17, and can relatively rotate between circular air pipe and dedusting body.Dedusting body 17 inwalls are provided with bipassage ring connected in star 24a, 24b.On circular air pipe 13 inwalls, be respectively equipped with the air guide through hole 25 communicating with two annular groove 24a, 24b; Be on circular air pipe 13 inwalls, be respectively equipped with air guide through hole 25 with two annular groove 24a, position that 24b is relative, and air guide through hole is communicated with corresponding annular groove.An annular groove 24b in two annular grooves is between two annular protrusions 16, and another annular groove 24a is positioned at two annular protrusion outsides.On the annular groove 24b bottom surface between two annular protrusions, be provided with exhaust hole 28.The annular groove 24a bottom surface that is positioned at two annular protrusion outsides is provided with air inlet through hole 34.The second cavity 52 inwalls are provided with two the dedusting through hole 32a, the 32b that are communicated with ambient air.Between air inlet through hole 34 and a dedusting through hole 32b, by admission line 33, be connected.Between exhaust hole 28 and another dedusting through hole 32a, by exhaust duct 30, be connected.Between exhaust duct 30 and exhaust hole 28, be also provided with solenoid valve 12d or mortor operated valve.In exhaust duct 30, be also provided with ventilating fan 31.Between air inlet through hole 34 and admission line 33, also solenoid valve 12d or mortor operated valve can be set.Between vent hole 34 in the present embodiment and admission line 33, do not establish solenoid valve 12d or mortor operated valve.
The specific works process of the compressor cylinder cover with silencing function of the present embodiment is as follows:
Wherein: solenoid valve 12a and 12b are normally open solenoid valve; Solenoid valve 12c and 12d are normally closed solenoid valve.
In compressor routine work process, solenoid valve 12a and 12b are in opening state, and the first vent and the second vent are on state; And solenoid valve 12c and 12d be in normally off, the 3rd vent and exhaust hole 28 are in closed condition;
In this process, gas, by sucking pipe 9 by solenoid valve 12a and the first vent 7, enters circular air pipe 13 and through netted silencer 26, then by solenoid valve 12b and the second vent 11, by gas guide groove 2, is entered in compresser cylinder.In this process, sucking pipe 9, the first cavitys 51, solenoid valve 12a and the first vent 7 coordinate formation RESONANT CAVITY MUFFLER (the first cavity is equivalent to resonant cavity); Netted silencer 26 is equivalent to resistive muffler; Four-way pore 18 and the second cavity 52 form expansion chamber silencing apparatus (the second cavity is equivalent to expansion chamber); The present embodiment is combined into one the silencing apparatus of multiple kind of structure, and in can effectively eliminating, the noise of low, high various different frequencies, its soundproof effect is good.
On the other hand, although the setting of netted silencer 26 has effectively improved erasure effect, baffler is easily assembled dust in long-term using process on netted silencer, and this will cause the air-flow flow resistance increase of baffler and the increase of atmospheric pressure lost; Thereby the baffler of the present embodiment (for example, the every work of compressor one month) after the every work of compressor a period of time, all will carry out automatically cleaning to netted silencer 26: its automatically cleaning process is as follows:
When compressor starts is worked, solenoid valve 12a and 12b are closed, solenoid valve 12c and 12d are opened; Ventilating fan 31 is opened simultaneously; Now, the first vent and the second vent are in closed condition, and the 3rd vent and exhaust hole 28 are on state.
In this process, gas, by sucking pipe 9 by solenoid valve 12c, the 3rd vent 23 and air guiding sleeve 22, enters the second cavity 52; Then by four-way pore 18, by gas guide groove 2, entered in compresser cylinder.
When air-flow is through in the process of air guiding sleeve 22, impeller 21 is rotated; Impeller 21 will drive axostylus axostyle and driving gear 20 to rotate when rotating, and then will drive driven gear 14 and circular air pipe 13 to rotate.In the process of rotating at circular air pipe 13, netted silencer 26 will overturn, shake in circular air pipe, and coordinate bristle 27 to make the dust releasing adhering on each circular net sheet 26a of netted silencer 26;
Meanwhile, ventilating fan 31 work, air-flow is entered in circular air pipe 13 through admission line 33, air inlet through hole 34, annular groove 24a and air guide through hole 25 by dedusting through hole 32b; Then by air guide through hole, annular groove 24b, exhaust hole 28, exhaust duct 30, dirt through hole 32a, discharged.Formation air-flow in this process in circular air pipe 13 by being discharged to the external world in circular air pipe 13, keeps the clean of netted silencer 26 by the dust coming off on netted silencer 26; Thereby can avoid baffler in long-term using process, on netted silencer, easily to assemble dust, cause the flow resistance increase of air-flow and the large problem of increase of atmospheric pressure lost.
