A receiving groove 802 is formed on the surface of the flange 7 for receiving and placing the limiting plate 811. The edge of the limiting plate 811 abuts against the bottom opening 6. A first... The limiting frame 804, and the first limiting frame 804 are fixedly connected to the limiting plate 811, are used to limit the bottom shape of the inner bladder 2. The silencing shell and the flange 7 are set as a separable and detachable structure, which directly improves the convenience of equipment maintenance. Through simple operation steps, the silencing shell and the flange 7 can be quickly separated without complicated disassembly process, thus greatly saving maintenance time and improving work efficiency. At the same time, this separable and detachable structure provides great convenience for subsequent rust removal, replacement and other operations of the silencing shell. Maintenance personnel can easily inspect or replace the silencing shell without worrying about the trouble caused by the fixed connection with the flange 7.

[0033] like Figure 2 , Figure 4As shown, the limiting plate 811 and the receiving groove 802 are provided with a sealing sheet 803, and the material of the sealing sheet 803 is rubber. The rubber sealing sheet 803 can tightly fit the tiny gap between the limiting plate 811 and the receiving groove 802, effectively preventing liquid leakage and ensuring the sealing and safety of the equipment. In addition, the rubber material has good elasticity and wear resistance, which can maintain stable sealing effect during long-term operation of the equipment, reduce maintenance requirements caused by aging or wear of the sealing element, and prolong the service life of the equipment.

[0034] First embodiment principle: when the first sound insulation shell 801 and the internal equipment are maintained, the flange 7 is first removed, and then the first sound insulation shell 801 can be directly separated from the inside of the receiving groove 802, realizing the separation operation of the first sound insulation shell 801 and the flange 7. After that, the first sound insulation shell 801 can be subjected to necessary rust removal or replacement operation; when the new first sound insulation shell 801 is replaced, the new first sound insulation shell 801 is first placed in the receiving groove 802, and the sealing sheet 803 is attached and arranged between the first sound insulation shell 801 and the receiving groove 802. Then the flange 7 is bolted with the bottom opening 6, and the outer edge of the bottom end of the inner capsule 2 is installed between the bottom opening 6 and the flange 7.

The arrangement of the through grooves 805 enables the liquid to flow more smoothly through the limiting frame during the flow process, avoiding the problem of liquid retention or blockage caused by narrow passages. At the same time, the equidistantly arranged through grooves 805 also ensure the uniformity of the liquid during the flow process, thereby improving the overall performance of the equipment.

[0040] As shown in Figure 1 , Figure 2 , the top of the equipment body 1 is provided with a top opening 4, and the top opening 4 is installed with a blind plate 5, which is used to abut the top end of the inner capsule 2. The bottom side of the equipment body 1 is provided with an inflation port 9, and the outer side of the inflation port 9 is threadedly sealed with a sealing cover, which facilitates the installation and replacement of the inner capsule 2. The arrangement of the top opening 4 and the blind plate 5 enables the inner capsule 2 to be easily put into or taken out of the equipment body, thereby improving the maintenance efficiency of the equipment. At the same time, the arrangement of the inflation port 9 provides a flexible inflation method for the equipment, which can adjust the pressure of the inner capsule according to actual needs, thereby ensuring stable operation of the equipment.

[0041] Second embodiment principle: when the equipment and the second sound attenuation shell 807 inside are being overhauled, the flange 7 is first removed, and then the installation ring 809 at the bottom of the first sound attenuation shell 801 can be directly threadedly detached from the threaded groove 808, thereby realizing the separation operation of the second sound attenuation shell 807 and the flange 7. After that, the second sound attenuation shell 807 can be subjected to necessary rust removal or replacement operation.

[0042] The technical scheme has the advantages of practical application, including but not limited to the following aspects:

[0043] 1、The sound attenuation shell and the flange are arranged in a detachable structure, and the separation operation is simple and convenient, thereby providing good convenience for subsequent rust removal and replacement of the sound attenuation shell.

[0044] 2、The first limiting frame and the second limiting frame can provide effective internal support for the bottom end of the inner bag during efficient operation of the equipment, prevent excessive deformation of the inner bag during contraction, and protect the inner sound attenuation mechanism.
