Technical Field

[0001] This utility model relates to the field of separation membrane technology, specifically to a self-cleaning serum protein continuous filtration separation membrane assembly. Background Technology

[0002] Serum protein filtration membrane modules are key devices for separating and purifying serum proteins from mixed solutions. Their working principle is based on the selective permeability of the membrane; driven by pressure differences, substances of different molecular weights are separated on both sides of the membrane. In biopharmaceuticals, clinical diagnostics, and biomedical research, the efficient separation and purification of serum proteins is crucial for obtaining high-purity biological products, accurate disease diagnosis, and in-depth research into biological mechanisms.

[0003] Currently, some serum protein filtration membrane separation modules with self-cleaning functions on the market often require shutdown during self-cleaning, causing serum protein filtration to stop and affecting production efficiency. Therefore, a self-cleaning continuous serum protein filtration membrane separation module is proposed to solve the problems mentioned above. Utility Model Content

Detailed Implementation

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] Reference Figures 1-5 As shown, a self-cleaning serum protein continuous filtration separation membrane assembly includes a first mounting frame 1 and a second mounting frame 2. A cleaning water storage tank 4 is fixedly connected to the upper end of the first mounting frame 1, and a serum protein storage tank 3 is fixedly connected to the upper end of the second mounting frame 2. The upper ends of the serum protein storage tank 3 and the cleaning water storage tank 4 are respectively connected to an inlet pipe 5 and an inlet water pipe 6. The lower ends of the serum protein storage tank 3 and the cleaning water storage tank 4 are respectively connected to an outlet pipe 7 and an outlet water pipe 9. The serum protein storage tank 3 is used to temporarily store the serum protein raw material to be filtered. When in use, the raw material is replenished through the inlet pipe 5, and the raw material in the tank enters the subsequent pipeline through the outlet pipe 7 by gravity. The cleaning water storage tank 4 temporarily stores the cleaning water used to clean the tubular membrane 14. When in use, the cleaning water is replenished through the inlet water pipe 6, and the cleaning water in the tank enters the subsequent pipeline through the outlet water pipe 9 by gravity. The lower end of the discharge pipe 7 is connected to a serum protein diversion pipe 8, and both ends of the serum protein diversion pipe 8 are equipped with a first serum protein shut-off valve 11. The lower end of the water discharge pipe 9 is connected to a water distribution pipe 10, and both ends of the water distribution pipe 10 are equipped with a first water valve 12. An upper connecting pipe 13 connects the first serum protein shut-off valve 11 and the first water valve 12. The first serum protein shut-off valve 11 is used to control the flow of serum protein into the corresponding upper connecting pipe 13. During the filtration stage, the corresponding valve is opened to allow the raw material to enter the working tubular membrane 14; during the cleaning stage, it is closed to cut off the supply of raw material to the tubular membrane 14. The first water valve 12 is used to control the flow of cleaning water into the corresponding upper connecting pipe 13. During the cleaning stage, the corresponding valve is opened to allow the cleaning water to enter the tubular membrane 14 to be cleaned; during the filtration stage, it is closed to cut off the supply of cleaning water to the tubular membrane 14. The outer surface of the upper connecting pipe 13 is connected to a tubular membrane 14, which is the core filtration component. The tubular membrane 14 separates serum proteins through its pores and also serves as a cleaning agent, rinsing away residual impurities on the membrane surface with cleaning water to achieve self-cleaning. Filtration and cleaning are performed alternately during use. The lower end of the tubular membrane 14 is connected to a lower connecting pipe 15, and a second serum protein shut-off valve 16 and a second water valve 17 are respectively installed at both ends of the lower connecting pipe 15.

[0023] Furthermore, a serum protein confluence tube 18 is connected between the two second serum protein shut-off valves 16. The second serum protein shut-off valve 16 is installed between the lower connecting pipe 15 and the serum protein confluence tube 18 to control whether the filtered serum protein flows into the serum protein confluence tube 18: it is opened during the filtration stage to allow the filtrate to flow into the serum protein confluence tube 18; it is closed during the cleaning stage to prevent sewage from entering.

[0024] Furthermore, a combined water pipe 20 is connected between the two second water valves 17. The second water valves 17 are installed between the lower connecting pipe 15 and the combined water pipe 20 to control whether the wastewater after cleaning flows into the combined water pipe 20: they are opened during the cleaning stage to allow the wastewater to flow into the combined water pipe 20; they are closed during the filtration stage to prevent the filtrate from mixing in.

[0025] Furthermore, the outer surface of the serum protein confluence tube 18 is connected to a discharge tube 19, which is the output port of the filtered serum protein and is connected to an external collection device; in use, the qualified filtrate is transported to the subsequent processing steps.

[0026] Furthermore, the outer surface of the water collection pipe 20 is connected to the discharge pipe 21, which collects the wastewater after cleaning by multiple tubular membranes 14 and centrally transports it to the discharge pipe 21; when in use, it serves as a wastewater collection channel for convenient centralized treatment or discharge.

[0027] Working Principle: In use, first connect the device to an external power source. Inject the serum protein to be filtered into the serum protein storage tank 3 through the feed pipe 5, and inject clean water into the clean water storage tank 4 through the water inlet pipe 6. Connect the discharge pipe 19 to the filtrate collection device and the discharge pipe 21 to the drainage system. The first serum protein shut-off valve 11, the second serum protein shut-off valve 16, the first water valve 12, and the second water valve 17 on the left are considered the first valve group. The first serum protein shut-off valve 11, the second serum protein shut-off valve 16, the first water valve 12, and the second water valve 17 on the right are considered the second valve group. Open the first serum protein shut-off valve 11 and the second serum protein shut-off valve 16 of the first group, and close the first water valve 12 and the second water valve 17 of the first group. Close the first serum protein shut-off valve 11 and the second serum protein shut-off valve 16 of the second group, and open the first water valve 12 and the second water valve 17 of the second group. Water valve 12 and water valve 17 are used. Serum proteins pass sequentially through serum protein storage tank 3, discharge pipe 7, serum protein diversion pipe 8, first group upper connecting pipe 13, first group tubular membrane 14, first group lower connecting pipe 15, serum protein merging pipe 18 and discharge pipe 19. Clean water passes sequentially through clean water storage tank 4, water outlet pipe 9, water diversion pipe 10, second group upper connecting pipe 13, second group tubular membrane 14, second group lower connecting pipe 15, merging pipe 20 and discharge pipe 21. When the first group tubular membrane 14 needs cleaning, the valves are operated in reverse: the first group filtration-related valves are closed, and its cleaning-related valves are opened; the second group filtration-related valves are opened, and its cleaning-related valves are closed. At this time, the second group filtration and the first group cleaning are continuously operated. According to the degree of fouling of the tubular membrane 14, the two groups of working states are switched periodically to continuously perform serum protein filtration and membrane self-cleaning.
