[0017] Example: Figure 1-4 As shown, the utility model provides a membrane filter for treating antigen dilution liquid, comprising a barrel 1, wherein the top and inner wall of the barrel 1 are jointly provided with a filter assembly 3, the top of the barrel 1 is movably connected to a filter cup body 4, the top and inner part of the filter cup body 4 are jointly provided with an anti-blocking assembly 2, the anti-blocking assembly 2 comprises a rocker 21, the bottom end of the rocker 21 is rotatably connected to the top of the filter cup body 4, the outer surface of the rocker 21 is rotatably connected to a connecting sleeve 27 via a rotating shaft, the inner wall of the rocker 21 is fixedly connected to a round rod 22, and the round rod The bottom end of 22 passes through the top of the filter cup body 4. The outer surface of the round rod 22 is fixedly sleeved with multiple stirring members 25. The cylinder 1 provides support and accommodation space for the entire filter. The filter cup body 4 is movably connected to the top of the cylinder 1, which is convenient for installation and disassembly, cleaning and maintenance. The rocker 21 can be manually operated and rotated, and the connecting sleeve 27 facilitates the operation of the rocker 21. The round rod 22 rotates under the drive of the rocker 21, so that the stirring member 25 stirs the antigen dilution liquid entering the filter cup body 4, reducing the clogging of the membrane filter structure during filtration and improving the filtration efficiency.

[0018] The filter assembly 3 includes a support frame 34, the outer surface of which is fixedly connected to the inner wall of the cylinder 1, and the top of the support frame 34 is of a through-type. The top of the support frame 34 is movably connected to the filter membrane body 32, and the top of the filter membrane body 32 is movably connected to the first rubber sealing ring 31. The support frame 34 provides stable support for the filter membrane body 32. The through-type design facilitates the liquid to flow through the support frame 34 to the filter membrane body 32 for filtration. The movably connected filter membrane body 32 is convenient for replacing filter membranes of different specifications to meet different filtration requirements. The first rubber sealing ring 31 enhances the sealing between the filter membrane body 32 and the support frame 34, preventing unfiltered liquid from bypassing the filter membrane body 32 and directly entering the cylinder 1, thereby ensuring the filtration effect. The structure of this filter assembly 3 is convenient for replacing the filter membrane body 32, and has better sealing during filtration, and can better filter the dilution liquid.

[0019] The top of the filter cup body 4 is provided with a liquid inlet 6, the top of the liquid inlet 6 is fixedly connected to a liquid adding tube 5, and the liquid inlet 6 and the liquid adding tube 5 provide an entry channel for the antigen diluent, facilitating the addition of the liquid to be filtered.

[0020] The plurality of stirring members 25 are distributed at equal intervals, and the outer surfaces of the plurality of stirring members 25 are all made of corrosion-resistant material. The stirring members 25 distributed at equal intervals can stir the liquid more evenly. The stirring members 25 are made of corrosion-resistant material and will not be corroded or damaged when in long-term contact with the antigen diluent, thereby extending the service life.

[0021] The inner wall of the filter cup body 4 is fixedly connected to a positioning frame 23, and a positioning groove 26 is provided at the top of the positioning frame 23. The inner wall of the positioning groove 26 is rotatably connected to a positioning ring 24 used in conjunction with the round rod 22. The positioning ring 24 is fixedly sleeved on the outer surface of the round rod 22, and the bottom end height of the round rod 22 is higher than the top height of the filter membrane body 32. The positioning frame 23 and the positioning ring 24 provide stable positioning and support for the round rod 22, ensuring that the round rod 22 remains stable during rotation. The bottom end height of the round rod 22 is higher than the top height of the filter membrane body 32, which can prevent the stirring member 25 from damaging the filter membrane body 32 during stirring.

[0022] The outer surface shape of the filter membrane body 32 and the outer surface shape of the first rubber sealing ring 31 are the same as the inner wall shape of the cylinder 1. The filter membrane body 32 and the first rubber sealing ring 31 are the same as the inner wall shape of the cylinder 1, ensuring sealing, preventing unfiltered liquid from leaking from the edge, and ensuring the filtering effect.

[0023] The top of the filter membrane body 32 is coated with a hydrophilic material. The hydrophilic material coating can make the antigen diluent spread more easily on the surface of the filter membrane body 32, thereby improving the filtration speed and efficiency.

[0024] A second rubber sealing ring 33 is fixedly connected to the top of the cylinder 1, and the inner wall shape of the second rubber sealing ring 33 is the same as the outer surface shape of the filter cup body 4. The second rubber sealing ring 33 enhances the sealing between the cylinder 1 and the filter cup body 4, prevents liquid leakage, and ensures the safety and stability of the filtration process.

[0025] Working principle: First, through the filter assembly 3, place the filter membrane body 32 to be used on the support frame 34, and then place the first rubber sealing ring 31 on the upper side of the filter membrane body 32.

[0026] Then, the filter cup body 4 is clamped on the cylinder body 1 , and the second rubber sealing ring 33 can improve the sealing performance of the connection between the filter cup body 4 and the cylinder body 1 .

[0027] Then, the antigen dilution liquid to be filtered is added into the filter cup body 4 through the liquid adding tube 5 in conjunction with the liquid inlet 6 , and the antigen dilution liquid is filtered through the filter membrane body 32 .

[0028] During the filtering process, the rocker 21 can be manually operated through the anti-blocking component 2. The connecting sleeve 27 on its outer surface facilitates the operator to rotate the rocker 21. The round rod 22 on the inner wall of the rocker 21 rotates under the drive of the rocker 21.

[0029] At the same time, the positioning frame 23, the positioning groove 26 and the positioning ring 24 cooperate to facilitate the positioning of the round rod 22 when it rotates.

[0030] The stirring elements 25 evenly spaced on the outer surface of the round rod 22 rotate accordingly to stir the liquid, so that the particulate matter of the antigen dilution liquid in the filter cup body 4 remains in suspension, thereby preventing the filter membrane body 32 from being blocked.

[0031] The filtered antigen dilution will flow into the cylinder 1 for storage. After the filtration is completed, the filter cup body 4 is removed from the cylinder 1 , and the first rubber sealing ring 31 and the filter membrane body 32 are removed using tweezers.
