Description
Technical field
This utility model relates to deafener technical field, the two-stage deafener of a kind of compressed air blowdown piping end.
Background technology
In pipeline during compressed air emptying, bigger emptying noise can be produced in line end.Line end deafener is the visual plant for reducing pipeline noise.When in pipeline, compressed air pressure is the highest, emptying noise is the biggest.When emptying noise is relatively big, and when the quiet requirement of environment is higher, the noise reduction amplitude of existing deafener is difficult to meet demand.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that the two-stage deafener of a kind of compressed air blowdown piping end, can significantly cut down emptying noise.
For realizing above-mentioned technical purpose, the scheme that this utility model provides is: the two-stage deafener of a kind of compressed air blowdown piping end, including interconnective inlet suction port and silencer casing, inlet suction port passes through bolt, packing ring, spring washer is fixing with silencer casing to be connected, silencer casing inner chamber is sequentially provided with the collar along air-flow direction, cellular porous cordierite muffling unit, porous sintered rustless steel muffling unit, and, between the collar and inlet suction port, between the collar and cellular porous cordierite muffling unit, it is equipped with gasket seal between cellular porous cordierite muffling unit and porous sintered rustless steel muffling unit, between porous sintered rustless steel muffling unit and the intracavity bottom of silencer casing, pad is set.
And, inlet suction port inner chamber along airflow direction in expansion shape.
The beneficial effects of the utility model are: simple in construction, are skillfully constructed；It is designed to expansion cavity inside inlet suction port, makes intraductal atmospheric pressure be gradually lowered, the generation of emptying noise can be reduced；Cellular porous cordierite muffling unit and porous sintered rustless steel muffling unit form two-stage noise reduction combination can significantly cut down emptying noise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1, inlet suction port, 2, bolt, 3, packing ring, 4, spring washer, 5, the collar, 6, silencer casing, 7, cellular porous cordierite muffling unit, 8, porous sintered rustless steel muffling unit, 9, the first gasket seal, the 10, second gasket seal, the 11, the 3rd gasket seal, 12, pad.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.
The present embodiment provides the two-stage deafener of a kind of compressed air blowdown piping end, as shown in Figure 1, including interconnective inlet suction port 1 and silencer casing 6, inlet suction port 1 is by bolt 2, packing ring 3, spring washer 4 is fixing with silencer casing 6 to be connected, silencer casing 6 inner chamber is sequentially provided with the collar 5 along air-flow direction, cellular porous cordierite muffling unit 7, porous sintered rustless steel muffling unit 8, and, the first gasket seal 9 it is provided with between the collar 5 and inlet suction port 1, the second gasket seal 10 it is provided with between the collar 5 and porous cordierite muffling unit, it is provided with the 3rd gasket seal 11 between cellular porous cordierite muffling unit 7 and porous sintered rustless steel muffling unit 8, between porous sintered rustless steel muffling unit 8 and the intracavity bottom of silencer casing 6, pad 12 is set.Inlet suction port 1 inner chamber in expansion shape, makes intraductal atmospheric pressure be gradually lowered along airflow direction, reduces emptying noise.
Cellular porous cordierite muffling unit 7 is mainly used in eliminating low frequency and intermediate frequency noise, also has certain noise reduction to high frequency noise；Porous sintered rustless steel muffling unit 8 is for eliminating intermediate frequency and high frequency noise further.Cellular porous cordierite muffling unit 7 and porous sintered rustless steel muffling unit 8 form two-stage noise reduction combination.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvement or deformation, these improve or deformation also should be regarded as protection domain of the present utility model.
