Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Referring to figs. 1 to Fig. 4, the present invention provides a kind of corrosion-resistant silencer of easy cleaning, including level-one silencer 2, second level disappear
Sound device 10, three-level silencer 12, level-one connecting line 8, second level connecting line 11 and installation supporting plate 4, the level-one silencer
2, secondary muffler 10 and three-level silencer 12 are all made of the noise elimination structure that foamed aluminium inner core is combined with expansion cavity, and the three-level disappears
Sound device 12 is located among level-one silencer 2 and secondary muffler 10, and the silencer interior air-flow channel is all made of acid and alkali-resistance corruption
Etching technique processing.
The level-one silencer 2 and secondary muffler 10 passes through sealing flange 6 and bolt 5 using level-one connecting line 8
It is attached using fast removing nut 7, air inlet pipeline 1 is connect by welding manner with level-one silencer 2, and vacuum flange structure is passed through
It is connect with vacuum pump exhaust port.
The secondary muffler 10 and three-level silencer 12 passes through sealing flange 6 and bolt using second level connecting line 11
5 are attached using fast removing nut 7.
Heat exchanging pipe 15 is wound outside the level-one connecting line 8, and cooling processing is carried out to discharge gas.
The level-one silencer 2, secondary muffler 10 and three-level silencer 12 are all made of cylinder type, embedded closed pore bubble
Foam aluminium inner core, innermost layer use perforated drum noise reduction.
It further include having muffler shell 23/103/123 outside the silencer 2/10/12, the muffler shell is through clip 3
