The outside for being fixed on inner membrance main body, the thickness of inner membrance ring gradually increases from inside to outside, upper surface and the inner membrance main body of inner membrance ring
Upper surface between angle a be 165-168 °；The outside for being fixed on inner membrance ring of the outer membrane component level of cirque structure, outside
The Formation cross-section that raised up in the middle part of membrane module is the arch membrane of arc-shaped structure, and the thickness of arch membrane gradually increases from middle to both sides
Add.
Further, what the bottom of the inner membrance main body was parallel to each other is provided with some first reinforcements, the first reinforcement
Cross sectional shape is isosceles triangular structure.
Further, the top of the outer membrane main body is provided with some second reinforcements in emitting shape, the second reinforcement
Cross sectional shape is square structure.
Further, it is provided with first boss and the first groove, first boss alternately between two neighboring second reinforcement
The truncated cone-shaped structure projected upwards, the first groove are the cylindrical structure to cave inward, and the height of first boss is less than second and added
The height of strengthening tendons, the depth of the first groove are equal to the height of first boss.
Further, the inner membrance main body is four layered structures, and from top to bottom, first layer is layer of polyurethane, the second layer is
Nanoweb layer, third layer are graphite film layer, and the 4th layer is polypropylene layer.
Further, nanoweb layer is formed by weaving by diameter 10-30nm nanofiber.
Further, the angle a between the upper surface of inner membrance ring and the upper surface of inner membrance main body is 166 °.
Further, the thickness as outside of inner membrance ring is twice of inner thickness.
In summary, stability of the present invention is good, ensure that acoustical behavior, improves intensity, adds service life.
