Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a cell separation filter. Background Art

[0002] A filter is a device for separating substances. There are many types of filters, one of which is a cell filter, which is used to filter and separate the required cells. The principle of filtration is to use a porous medium to prevent substances larger than the pore size from passing through, while substances smaller than the pore size pass through smoothly to achieve the effect of separation and filtration. Traditional cell separation filters use centrifugal methods to facilitate cell filtration. The cells are placed inside the separation filter barrel and then rotated for centrifugal separation. However, the cells inside the traditional cell separation filter are in a static state during use, resulting in slow separation speed and low efficiency, which increases the time for cell separation and filtration and cannot meet people's needs.

[0003] In summary, the utility model solves the existing problems by designing a cell separation filter. Utility Model Content

Limiting blocks 11 are symmetrically installed at both ends of the outer ring surface of the separation frame 10. A cylinder cover 12 is installed on the top of the separation filter cylinder 9, and a feed pipe 13 is installed at one end of the top of the cylinder cover 12. A sleeve 14 is installed at the bottom of the cylinder cover 12, and a threaded rod 15 is installed at the bottom of the sleeve 14.

[0024] Specifically, refer to Figure 3 The bottom of the threaded rod 15 is fixedly connected to the inner bottom of the separation frame 10, and the top of the threaded rod 15 extends into the interior of the sleeve 14. The outer annular surface of the threaded rod 15 is threadedly connected to the inner wall of the sleeve 14, thereby ensuring that the sleeve 14 rotates so that the inner wall of the sleeve 14 rotates along the outer annular surface of the threaded rod 15, driving the separation frame 10 to rise and fall inside the separation filter cylinder 9, so that the cells are always in an active state.

[0025] Furthermore, the output end of the rotating motor 8 extends through the interior of the base 7 to the top of the base 7 and is connected to the bottom of the separation filter cylinder 9, thereby ensuring that the separation filter cylinder 9 is driven by the rotating motor 8 to rotate and separate the internal cells.

[0028] The working process of the utility model is as follows: using a cell separation filter designed by the present invention, in the process of separating and filtering cells, firstly, the box cover 5 is opened by the handle 6, and the cells to be separated and filtered enter the interior of the separation filter cylinder 9 through the feed pipe 13, and then the box cover 5 is closed, and the separation filter cylinder 9 is driven by the rotating motor 8 to rotate and perform rotational centrifugal separation on the cells inside. In the process of the separation filter cylinder 9 rotating, the first bevel gear 16 is driven to rotate by the driving servo motor 17, and the first bevel gear 16 drives the second bevel gear 18 to rotate, and the second bevel gear 18 rotates synchronously to drive the sleeve 14 to rotate, and the rotation of the sleeve 14 causes the inner side wall of the sleeve 14 to rotate along the outer ring surface of the threaded rod 15, driving the separation frame 10 in The separation filter cartridge 9 is raised and lowered, and the cells in the separation frame 10 enter the separation frame 10 through the through groove 1001 during the lifting process, so that the cells inside the separation filter cartridge 9 are always in an active state. The limiting block 11 slides inside the slide groove 901 to increase the stability of the lifting and lowering of the separation frame 10 inside the separation filter cartridge 9. The internal separation and filtration conditions can be monitored through the observation window 4. The cells filtered by the filter mesh outside the separation filter cartridge 9 fall into the interior of the box body 1 and are discharged through the discharge pipe 3 for collection. The cartridge cover 12 can be opened to synchronously take out the separation frame 10 to clean the separation frame 10 and the interior of the separation filter cartridge 9. The operation is convenient, and the centrifugal effect of the cells and the speed of separation and filtration are increased by rotating and lifting the cells.
