The top of opening cylinder 21 is given prominence to and is higher than on the top 231 of spring sheet screens 23.Again as shown in Figure 2, the tip side opening 212 of opening cylinder 21 is given prominence to and is higher than on top 231.In the present embodiment, inlet and outlet parts 100 are vertical the installation, and the top that opening cylinder 21 is positioned at frame plate 22 is provided with, and shows that in the drawings the top 231 of elasticity screens sheet 23 is higher than the top of opening cylinder 21 at the length direction of opening cylinder 21.If inlet and outlet parts 100 are installed for level, the top 231 of elasticity screens sheet 23 still protrudes in the top of opening cylinder 21 on the length direction of opening cylinder 21.
And the central shaft of the more close opening cylinder 21 of inwall of the top 231 ratio open cylinders 21 of spring sheet screens 23.That is to say that this top 231 is compared with the inwall of opening cylinder 21, more near the central side of opening cylinder 21.Spring sheet screens 23 is given prominence to formation protuberance 232 to the outside of opening cylinder 21 between top 231 and root 234, middle part 210 diameters of these protuberance 232 ratio open cylinders 21 are more outstanding, promptly this protuberance 232 is compared with the outer wall at the middle part 210 of opening cylinder 21, further from the center of opening cylinder 21.
And 231 beginnings are provided with protuberance 232 and root 234 in order from the top in above-mentioned spring sheet screens 23, and 231 to the skewed upper end 233 of protuberance 232 formation from the top, and this upper end 233 is positioned at outside the top of opening cylinder 21.What is called is positioned at outside the top of opening cylinder 21, is meant as shown in Figure 3, and any one part of upper end 233 all is positioned at the outside or the top of the tip side opening 212 of opening cylinder 21.
