Abstract
The utility model discloses a totally enclosed air-breathing silencer for refrigerating compressors, mainly comprising an upper silencing chamber and a lower silencing chamber. The upper silencing chamber is provided with an outlet connected with a compressor cylinder. A side of the lower silencing chamber is provided with an air collector. The interior of the lower silencing chamber is provided with a hook shaped communicating vessel. The lower silencing chamber is separated by a longitudinal baffle into two cavities with different capacities, and the ratio is 1:3. The utility model not only can decrease the frequency of the certain air sucking noisy sections, but also has the advantages of clear structure and fluent flow channels. The totally enclosed air-breathing silencer for refrigerating compressors can better raise the refrigeration effect of the compressors.
Description
(1) technical field: the utility model belongs to muffling device, is specifically related to a kind of hermetically sealed compressor air suction silencer.
(2) background technique: by retrieval, Empresa Brasileira De Compressores S/A has proposed No. 00802704.8 application for a patent for invention " suction muffler of air-tight compressor " in 2002.2.24 day to Patent Office of the People's Republic of China, this device is except that having hollow body that common silencer often has, gas access ozzle, outlet ozzle, a plurality of chamber and gas circulation duct, what also be about in described last chamber that hollow body is separated out up and down is provided with a deflector wall in the nearest chamber of outlet ozzle, last chamber is divided into two two parts that shape and size are all different; Simultaneously, the outlet end of gas outlet ozzle and aforementioned gas communication pipeline is positioned at the position of staggering mutually; This device mainly by being arranged on the sound that deflector wall in the last chamber decays and produces in the last chamber, obtains and the vibration of sound short wavelength's high frequency that it doesn't matter, reduces the noisiness that produced by compressor thereby reach.
(3) summary of the invention: the purpose of this utility model just provides a kind of hermetically sealed compressor air suction silencer, by architecture advances to existing baffler, specific air suction and noise band frequency can be reduced, simultaneously, the deficiency of existing muffler structure complexity, expense costliness can be solved again.
The utility model comprises anechoic chamber, following anechoic chamber, top, last anechoic chamber has the outlet that is connected with compresser cylinder, following anechoic chamber one side is equipped with gas collector, be provided with the hook-type connecting vessels in the following anechoic chamber cavity, its improvements are: the anechoic chamber is separated into the cavity volume of two volumes that vary in size under a. by longitudinal baffle; B. the outlet of hook-type connecting vessels closely is connected through too small volume cavity volume and with last baffler import; C. on the hook-type connecting vessels, be provided with the dew window.
Above-mentioned anechoic chamber down is separated into 1: 3 two not isometric cavity volume by longitudinal baffle; Portion is provided with the dew window at hook-type connecting vessels lateral bending.
When compressor operating, the sucking pipe from the housing sucks low-temp low-pressure gas, and expanding after the buffering of gas collector, the throttling of air inlet honeycomb duct enters down the anechoic chamber subsequently; Gas expands in 1/3 volume cavity volume after the import of hook-type connecting vessels enters, and reexpands to revealing window place gas, and enters in the cavity volume of 2/3 volume and carry out acoustic attenuation, enters hook-type connecting vessels top once more; Outlet by last anechoic chamber enters cylinder.Owing to the outlet of hook-type connecting vessels is closely connected with the import of last anechoic chamber, be convenient to gas and directly enter anechoic chamber's passage glibly, reduced the loss of gas in runner, after expanding, outlet decays through a pressure again again, and decrease of noise functions is strengthened more.
The utility model gas flow length effectively reduces, and the loss of gas in circulation significantly reduced, and compares with common baffler, and it is bright and clear to have structure, and runner is unimpeded, can reduce the characteristics of specific air suction and noise band frequency; Also therefore characteristics and improved the refrigerating efficiency of compressor have reduced power consumption.

Fig. 2 is the utility model master apparent direction structural representation;
Fig. 3 is the vertical section structure schematic representation of Fig. 2;
Fig. 4 is an A-A direction sectional structure schematic representation among Fig. 2.
(5) embodiment:
Referring to accompanying drawing, the utility model comprises anechoic chamber 1, and following anechoic chamber 2 has the outlet 3 that is connected with compresser cylinder at top, last anechoic chamber, and following anechoic chamber one side is equipped with gas collector 4, is provided with hook-type connecting vessels 5 in the following anechoic chamber cavity; Last anechoic chamber in the utility model is actually by lid shape part I and constitutes with the passage II of tubulose anechoic chamber that is arranged on the caping, following anechoic chamber roughly is square cavity for cross section then, last noise reduction chamber cap is at following anechoic chamber's cavity top edge, and with proper device for example buckle 6 be fixed on this edge.It is 1: 3 two cavity volume C1, C2 that vary in size that described anechoic chamber down is separated into volume by longitudinal baffle 7, this dividing plate inserts in the groove on the cavity sidewalls III of anechoic chamber down and is fixed, as shown in Figure 4, and be arranged on down its imports 8 of hook-type connecting vessels 5 in the anechoic chamber near the air inlet honeycomb duct 9 at gas collector 4 rear portions, from aforementioned barriers, pass then, behind 2/3 cavity volume C2, from dividing plate, pass again, its outlet end 10 by stretch out among the little volume cavity volume C1 and with the top on baffler inlet closely be connected, this connection can be adopted convex-concave connection or outer clamping mode; Its objective is that being convenient to gas directly enters among the passage II of anechoic chamber, thereby enter cylinder through exporting 3 smoothly.Lateral bending portion at the hook-type connecting vessels is provided with a dew window 11, makes the gas that enters from the connecting vessels import enter step expansion, throttling the 2/3 cavity volume C2 by this dew window herein, to eliminate air-breathing section noise to a greater extent.
