[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] like Figure 1 As shown;

[0044] A filtering device for filtering immune cell separation filtrate comprises a filter barrel 1, a liquid discharge pipe 2 installed at the bottom of the filter barrel 1, and a liquid inlet pipe 3 arranged on the outer side wall of the filter barrel 1.

[0045] In this embodiment: During the liquid-based cell extraction process, filtration is required to ensure the purity of the filtrate. Traditional filtration generally uses a filter screen and a funnel for filtration, which is relatively simple. At the same time, the filtrate is mixed with connective tissue with high viscosity, which can easily clog the filter holes and cause accumulation during the filtration process, thereby reducing the filtration effect of the filter screen and making the filtration insufficient. On this basis, a filter component 4 is added, which facilitates filtration of the filtrate.

[0046] like Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 11 and Figure 12 As shown:

[0047] In combination with the above content, in order to facilitate the filtering of the filtrate, a filter assembly 4 is also included which is installed in the filter barrel 1. The filter assembly 4 includes an L-shaped mounting plate 41, a filter barrel 42, a sewage pipe 44, a sealing cover 45 and a sewage collecting hopper 401. Two L-shaped mounting plates 41 are symmetrically installed in the filter barrel 1, and a filter barrel 42 is provided on the inner bottom surface of the filter barrel 1. The filter barrel 42 is connected to the outer surfaces of the two L-shaped mounting plates 41 by bolts. A sealing cover 45 is installed at the opening of the filter barrel 1, and a sewage pipe 44 is installed on the bottom surface of the filter barrel 1. The sewage pipe 44 is connected to the filter barrel 1, and a sewage collecting hopper 401 is provided directly below the sewage pipe 44.

[0048] In this embodiment: when filtering the filtrate, the filtrate is drained into the filter barrel 1 through the provided liquid inlet pipe 3, and the filtrate is filtered through the filter barrel 42 installed in the filter barrel 1, and the connective tissue with high viscosity mixed in the filtrate is blocked on the surface of the filter barrel 42, and the filtrate is discharged through the filter barrel 42 through the sewage pipe 44 installed on the bottom surface of the filter barrel 1, and the connective tissue with high viscosity blocked on the surface of the filter barrel 42 enters the sewage pipe 44 for centralized collection.

[0049] It should be noted that the outer wall of the filter barrel 1 is tilted at the setting of the liquid inlet pipe 3, so that when the filtered liquid enters the inner cavity of the filter barrel 1 from the liquid inlet pipe 3, it can form a vortex flow due to the tangential direction of entry, so as to make the contact between the filtered liquid and the filter barrel 42 more comprehensive, and make the filtered liquid flow down along the inner wall of the filter barrel 1 under the action of centrifugal force, and flush the connective tissue with higher viscosity filtered on the surface of the filter barrel 42 into the sewage pipe 44.

[0050] In an optional embodiment: a plug-in groove 47 is provided on the surface of the sewage pipe 44, a sealing strip 46 is inserted into the plug-in groove 47, a through hole 48 is provided on the surface of the sealing strip 46, a pull ring 49 is integrally formed on one side of the sealing strip 46, and a limiting protrusion is provided on the other side of the sealing strip 46.

[0051] In this embodiment: Based on this setting, after the filtration is completed, the connective tissue with high viscosity filtered in the filter barrel 42 is flushed into the sewage pipe 44 for discharge. By manually pulling the pull ring 49 on one side of the sealing strip 46, the sealing strip 46 is driven to move to one side in the plug-in groove 47 opened on the surface of the sewage pipe 44, and the through hole 48 opened on the surface of the sealing strip 46 is connected to the inner diameter of the sewage pipe 44, so that the connective tissue with high viscosity in the sewage pipe 44 is discharged, and the connective tissue with high viscosity is caught by the sewage collecting bucket 401 set directly below the sewage pipe 44, and collected and processed in a centralized manner. At the same time, the limiting protrusion can prevent the sealing strip 46 from slipping out of the plug-in groove 47 when it moves to one side in the plug-in groove 47 opened on the surface of the sewage pipe 44.

[0052] In an optional embodiment, the diameter of the through hole 48 is the same as the inner diameter of the sewage pipe 44 , the width of the sealing strip 46 is smaller than the outer diameter of the sewage pipe 44 , and the width of the sealing strip 46 is larger than the inner diameter of the sewage pipe 44 and is adapted to the plug-in groove 47 .

[0053] In this embodiment: Based on this setting, in order to ensure that the sealing strip 46 can slide in the plug-in groove 47 opened on the surface of the sewage pipe 44, the opening and closing of the sewage pipe 44 can be controlled by adjusting the position of the through hole 48 on the sealing strip 46 and the inner diameter of the sewage pipe 44, so as to facilitate the discharge of connective tissue with higher viscosity.

The surface of the sealing cover 45 is installed with a reduction motor 51. The rotating shaft of the reduction motor 51 passes through the surface of the sealing cover 45 and is connected to the connecting sleeve 52 provided in the filter barrel 1. The outer wall of the connecting sleeve 52 is installed with a plurality of levers 53, and the plurality of levers 53 corresponds to the plurality of connecting rods 54 one by one, and the levers 53 abut against the outer wall of the connecting rod 54.

[0056] In this embodiment: by controlling the reduction motor 51 to start, the lever 53 on the connecting sleeve 52 can be rotated, and the lever 53 can be brought into contact with the provided connecting rod 54, driving the L-shaped scraper 55 to rotate on the surface of the filter barrel 42, so as to scrape the connective tissue with high viscosity attached to the surface of the filter barrel 42 to the bottom surface of the filter barrel 1, thereby ensuring the filtering effect of the filter barrel 42, and allowing the filtrate to flush the connective tissue with high viscosity into the sewage pipe 44 under the action of centrifugal force.

[0057] In an optional embodiment: the bottom ends of several L-shaped scrapers 55 are commonly connected to an annular rotating rack 56, the annular rotating rack 56 is sleeved on the bottom outer surface of the filter barrel 42, and a plurality of lower sewage troughs 57 are opened at equal intervals on the surface of the annular rotating rack 56, and a plurality of V-shaped scraping blocks 59 are installed at equal intervals on the bottom surface of the annular rotating rack 56, and the bottom surfaces of the plurality of scraping blocks 59 are all in contact with the inner bottom surface of the filter barrel 1.

[0058] In this embodiment: Based on this setting, the annular rotating rack 56 is provided to improve the stability of the L-shaped scraper 55 during rotation, ensuring that one side of the L-shaped scraper 55 can contact the surface of the filter barrel 42. At the same time, the lower sewage trough 57 is provided for convenient cooperation. The filtrate will flush the high-viscosity connective tissue falling on the annular rotating rack 56 from the lower sewage trough 57 to the bottom surface of the filter barrel 1 under centrifugal force.

[0060] In this embodiment: Based on this setting, when the annular turret 56 is installed on the outside of the filter barrel 42, the annular turret 56 can be inserted from the surface of the filter barrel 42. At this time, the resistance roller 504 pushes the spring 503 to perform compression deformation, and causes the annular turret 56 to slide on the surface of the filter barrel 42 until the resistance roller 504 slides into the annular groove 507 opened on the outer side wall of the bottom of the filter barrel 42, thereby making the annular turret 56 more stable when rotating on the outer surface of the filter barrel 42.

[0061] In an optional embodiment, two disassembly holes 506 are symmetrically provided on one end surface of the threaded sleeve 502 .
