[0030] Referring to Figures 1-5, the ceramic membrane module and the unit assembly using this module include a water receiving chassis 1, twelve single membrane modules 8, and two empty membrane modules 9. A frame 2 is mounted on the top of the water receiving chassis 1. The twelve single membrane modules 8 are connected in series via six connecting pipes 10. Each single membrane module 8 has a clear liquid outlet a11 fixedly connected to its inner wall. A booster pump 12 is mounted on the side wall of the water receiving chassis 1. The input end of the booster pump 12 is fixedly connected to a membrane module inlet 13, and the output end of the booster pump 12 is fixedly connected to a flow guide channel 14. Two clear liquid upper outlet pipes 15 are connected between the empty membrane group 9 and the twelve single membrane groups 8. A clear liquid lower outlet pipe 16 is fixedly connected to the inner wall of the clear liquid upper outlet pipe 15. A cleaning liquid outlet b18 is fixedly connected to the outer edge of the twelve single membrane groups 8. An exhaust pipe 25 is connected to the outer edge of the twelve single membrane groups 8. A sewage discharge pipe c22, a sewage discharge pipe b23, and a sewage discharge pipe a24 are fixedly connected to the outer edge of the twelve single membrane groups 8 respectively. A membrane group outlet 21 is fixedly connected to the outer edge of the clear liquid upper outlet pipe 15.

[0031] Referring to Figures 1 and 2, a fixing plate 3 is fixedly installed at the bottom of the frame 2. A stud 4 is threadedly connected to the inner wall of the fixing plate 3. A nut 6 is threadedly connected to the outer edge of the stud 4. An anti-slip pad 5 is fixedly installed at the bottom of the stud 4, so that the anti-slip pad 5 can be stably placed on the top of the water receiving base 1, thereby ensuring that the frame 2 can be stably set above the water receiving base 1 and preventing it from easily tipping over or shaking.

[0032] Referring to Figure 3, two wire grooves 7 are symmetrically fixedly installed on the top of the frame 2, which makes it easy for users to place the wire harness into the inside of the wire grooves 7 for positioning the wire harness.

[0033] Referring to Figure 1, a circulation pipe 17 is fixedly connected to the inner wall of the clear liquid outlet pipe 15. A valve is installed inside the circulation pipe 17 so that the waste yeast after fermentation can be smoothly discharged to the outside through the circulation pipe 17.

[0034] Referring to Figures 3 and 5, a circulation pump 20 is fixedly installed on the top of the frame 2, and a circulation pipe is fixedly connected to the output end of the circulation pump 20, so that beer and turbid liquor enter the circulation pipe from the inlet and circulate.

[0035] Referring to Figures 3 and 4, a passage pipe is fixedly connected to the bottom of the single membrane module 8, and the passage pipe is connected to the clear liquid outlet pipe 15, so that the beer and sake filtered by the single membrane module 8 can be discharged into the beer tank for collection and storage through the clear liquid outlet pipe 15.

[0036] Referring to Figure 1, the top of the frame 2 is fixedly connected to a waste yeast liquid outlet 19, which is connected to the circulation pipe 17. This allows backwashing to be performed by opening the branch valve of the waste yeast liquid outlet 19, the top and bottom valves of the waste yeast liquid outlet 19, and the bottom drain valve. Forward cleaning can be performed by opening the circulation pipe inlet valve and following the filter pipe opening method. The liquid at the outlet returns to the cleaning liquid station.

[0037] Referring to Figure 1, two empty membrane groups 9 are installed inside the frame 2, and the circulation pipe is connected to the two empty membrane groups 9 and the twelve single membrane groups 8, so that filtration is carried out by using the cross-flow filtration principle. The two empty membrane groups 9 can be used to expand the internal volume of the circulation pipe, reduce water hammer, and extend the filtration time.

[0038] Working principle:

[0039] Filtration: The fermentation broth enters from the membrane module inlet 13, passes through the booster pump 12 and the flow channel 14, and enters the circulation pipe 17. The circulation pump 20 is turned on, and using the cross-flow filtration principle, the clear liquid from the twelve single membrane modules 8 passes through the clear liquid outlet a11, is collected by the clear liquid upper outlet pipe 15, and exits from the membrane module outlet 21, flowing to the sake tank for storage.

[0040] The turbid liquid from the twelve single membrane modules 8 is kept in the circulation pipe 17. When the filtration is finished, the waste yeast can be discharged through the waste yeast liquid outlet 19, or it can be directly discharged through the sewage pipes c22, b23 and a24.

[0041] Forward circulation cleaning: The cleaning solution enters from the membrane module inlet 13, passes through the booster pump 12, and enters the circulation pipeline 17 through the guide channel 14. The circulation pump 20 is turned on, and using the cross-flow filtration principle, the clear liquid from the twelve single membrane modules 8 passes through the clear liquid outlet a11, is collected by the clear liquid upper outlet pipeline 15, and exits from the membrane module outlet 21, flowing to the cleaning liquid tank for recovery.

[0042] Reverse cleaning discharge: The cleaning solution enters from the membrane module inlet 13, passes through the booster pump 12 and the guide channel 14, and enters the upper outlet pipe 15 and the lower outlet pipe 16 of the clean liquid to backwash the membrane. The backwash liquid permeates into the circulation pipe 17 and is directly discharged through the drain pipes c22, b23 and a24.

[0043] Reverse circulation cleaning: The cleaning solution enters from the membrane module inlet 13, and enters the upper outlet pipe 15 and lower outlet pipe 16 of the clean liquid through the guide channel 14 of the booster pump 12 to backwash the membrane. The backwash liquid permeates into the circulation pipe 17 and flows to the cleaning liquid tank for recovery through the cleaning liquid outlet b18.

[0044] When the fermentation broth or cleaning solution enters the membrane module through the membrane module inlet 13, the gas inside the membrane module is fully discharged through the exhaust pipe 25. If the gas is not completely discharged, the circulation flow rate of the circulation pump 20 will be unstable, and cavitation will affect the circulation effect of filtration and cleaning.
