The second arcuate segment 27 extends outwardly from the second volute segment 23 and the second arcuate segment 27 is removably coupled to the first arcuate segment 17. The third inclined extending section 28 is inclined towards the second spiral opening 22, and the first inclined extending section 18 and the third inclined extending section 28 are detachably connected.
In order to adapt to the air-out requirement and ensure better anti-surge and noise reduction effects, in this embodiment, the horizontal length M of the second tongue 25 is equal to the horizontal length C of the first tongue 14, and the horizontal length N of the first air-out section 26 is equal to the sum of the horizontal length a of the second air-out section 16 and the horizontal length B of the second volute tongue 7.
