[0002] Beer filtration is a crucial step in the beer production process, affecting the beer's appearance, taste, and both biological and abiotic stability. After fermentation, mature beer contains suspended solids such as yeast and proteins. These substances can cause the beer to become cloudy during storage. Therefore, ceramic membrane modules are used in beer production to achieve filtration.
[0003] Traditional ceramic membrane modules use single-layer flange sealing or adhesive fixing, which currently has the following drawbacks: 1. Uneven sealing pressure leads to leakage risk; 2. Gaps between the porous plate and the membrane affect filtration accuracy; 3. The modules are mostly cast in one piece, making maintenance difficult. Utility Model Content

In high-temperature environments, ordinary materials are prone to deformation or aging, leading to sealing failure. However, the high-temperature resistant rubber gasket can remain stable under extreme conditions, effectively preventing the problem of sealing materials failing under high temperature and high pressure conditions.

[0010] By adopting the above technical solution, the sealing performance at the gap can be enhanced through the combined use of the annular groove and the sealing ring, and the sealing performance of the EDPM sealing ring itself can be combined to form a second sealing layer.

[0015] In a preferred embodiment, the inner wall of the cylindrical body is fixedly connected with guide ribs at equal intervals, and a fixing frame is fixedly connected inside the cylindrical body, with multiple cylindrical ceramic membranes fixedly installed inside the fixing frame.
[0016] By adopting the above technical solution, the use of a fixing frame can provide support for multiple cylindrical ceramic membranes, and the use of guide ribs can reduce turbulent impact.
[0017] In a preferred embodiment, both ends of one side of the cylinder body are fixedly connected to liquid inlet pipes, and the side of the upper flange away from the cylinder body is fixedly connected to liquid outlet pipes.

A pressure plate 13 is located on the side of the sealing ring EDPM 12 away from the perforated plate 11. A high-temperature resistant rubber gasket 14 is located at the top of the pressure plate 13. Holes that cooperate with the cylindrical ceramic membranes 10 are formed inside the perforated plate 11, the sealing ring EDPM 12, the pressure plate 13, and the high-temperature resistant rubber gasket 14. The outer walls of the perforated plate 11, the sealing ring EDPM 12, the pressure plate 13, and the high-temperature resistant rubber gasket 14 are all in close contact with each other. A sealing component is located inside the sealing ring EDPM 12, which is connected to the upper flange 5 and the cylindrical body flange. A high-temperature resistant rubber gasket 14 is placed between the three layers to form the first sealing layer. The main functions of the high-temperature resistant rubber gasket 14 include sealing and protection. In high-temperature environments, ordinary materials are prone to deformation or aging, leading to sealing failure. However, the high-temperature resistant rubber gasket 14 can remain stable under extreme conditions, effectively preventing the problem of sealing material failure under high temperature and high pressure conditions. Through the action of the pressure plate 13, the sealing ring EDPM12 in the sealing assembly can be compressed. Combined with the sealing performance of the sealing ring EDPM12 itself, a second sealing layer is formed. A sealing mating surface 17 for use with the sealing ring EDPM12 is processed on the top of the perforated plate 11 to form a third sealing layer. The multi-layer sealing structure can avoid the risk of leakage due to uneven sealing pressure.
[0029] Specifically, the sealing assembly includes a sealing ring 16 fixedly connected to the top of the sealing ring EDPM12 and located above the hole. The inner wall of the hole of the pressure plate 13 is provided with annular grooves 15 that cooperate with the sealing ring 16. Through the cooperation of the annular grooves 15 and the sealing ring 16, the sealing performance at the gap can be enhanced to reduce leakage. The sealing assembly also includes a sealing mating surface 17 opened at the top of the perforated plate 11. The sealing mating surface 17 can improve the sealing mating performance of the perforated plate 11. The sealing mating surface 17 is tightly fitted with the sealing ring EDPM12. The top of the cylinder body 1 is provided with a quick-release assembly, which includes a cylinder flange 3 fixedly connected to the top of the cylinder body 1. The high-temperature resistant rubber gasket 14 is provided with an upper flange 5 on the side away from the pressure plate 13.
[0030] Specifically, the quick-release assembly also includes locking nuts 7 equidistantly positioned at the top of the upper flange 5, and screws 4 equidistantly inserted inside the cylindrical flange 3. Through the cooperation of screws 4 and locking nuts 7, the upper flange 5 and the cylindrical flange 3 on the cylindrical body 1 can be locked and fixed. Screws 4 are threadedly connected to the corresponding locking nuts 7, and locking nuts 7 abut against the outer wall of the upper flange 5. Guide ribs 8 are fixedly connected at equal intervals on the inner wall of the cylindrical body 1. Through the use of guide ribs 8, turbulent impact can be reduced. A fixing frame 9 is fixedly connected inside the cylindrical body 1, which can provide support for multiple cylindrical ceramic membranes 10. Multiple cylindrical ceramic membranes 10 are fixedly installed inside the fixing frame 9. Liquid inlet pipes 2 are fixedly connected to both ends of one side of the cylindrical body 1, and liquid outlet pipes 6 are fixedly connected to the side of the upper flange 5 away from the cylindrical body 1. Through the cooperation of liquid inlet pipes 2 and liquid outlet pipes 6, it can be used for beer filtration.
[0031] Working principle: First, during the beer production process, a high-temperature resistant rubber gasket 14 is placed between the upper flange 5 and the cylindrical flange 3 to form the first sealing layer. The main functions of the high-temperature resistant rubber gasket 14 include sealing and protection. Under high-temperature environments, ordinary materials are prone to deformation or aging, leading to sealing failure. However, the high-temperature resistant rubber gasket 14 can remain stable under extreme conditions, effectively preventing the problem of sealing material failure under high temperature and high pressure conditions. Through the action of the pressure plate 13, the sealing ring EDPM12 can be pressed to improve the fit. And through the cooperation of the annular groove 15 and the sealing ring 16, the joint can be strengthened. The sealing performance at the gaps, combined with the sealing performance of the sealing ring EDPM12 itself, forms a second sealing layer. A sealing mating surface 17, which is used to cooperate with the sealing ring EDPM12, is machined on the top of the perforated plate 11 to form a third sealing layer. In short, the multi-layer sealing structure can avoid the risk of leakage due to uneven sealing pressure. With the use of screw 4 and locking nut 7, screw 4 can pass through the perforated plate 11 and the upper flange 5 in sequence, and is locked with locking nut 7. This enables the quick replacement and maintenance of various components inside the cylinder body 1, making maintenance more convenient.
