Description

Technical Field

[0001] The present application relates to the technical field of experimental instruments, and in particular to a rotary filter. Background Art

[0002] In biological science research, filtration technology is an important means of studying the structure and function of biomolecules. Filtration can be used to separate, purify, and concentrate specific biomolecules, allowing for further analysis and research.

[0003] For example, biomolecule filtration can effectively separate and purify target molecules such as proteins, nucleic acids, virus particles, etc. from complex biological samples. This is crucial for the research and development of biopharmaceuticals.

[0004] Sterilization and virus removal: In the production of pharmaceuticals and biological products, filtration is a key step in ensuring product sterility and virus-free. By using a filter membrane with an appropriate pore size, bacteria and viruses can be removed from the sample to ensure product safety.

[0005] Remove impurities. Biological samples often contain a variety of impurities, such as cell debris, protein aggregates, endotoxins, etc. Filtration can remove these impurities and improve the purity and quality of the samples.

[0006] Concentration and filtration techniques, such as ultrafiltration, can be used to concentrate biomolecules, reducing sample volume and increasing concentration, which is very useful for subsequent analysis and applications.

[0007] In summary, biomolecule filtration plays a key role in ensuring the safety, efficacy, and quality of biopharmaceuticals and is an indispensable technology in biopharmaceutical and bioscience research.

[0008] In addition, the filter materials of the filtering equipment in the existing technology are mostly of one specification, and can only filter one target molecule when used, and cannot filter different target molecules. As a result, the filter materials in the filtering device must be frequently replaced when filtering different biological molecules, which increases costs and affects work efficiency. It is also very inconvenient to replace the filter materials. Therefore, it is necessary to improve the existing technology.

[0009] Therefore, a rotary filter is provided, which can realize different filter materials by rotating according to different filtering requirements and can perform multi-stage filtering. Utility Model Content

[0034] Example 1

[0035] The filter materials of existing filtration equipment are mostly of one specification and can only filter one target molecule when used, but cannot filter different target molecules. As a result, the filter materials in the filtration device must be frequently replaced when filtering different biological molecules, which increases costs and affects work efficiency. It is also very inconvenient to replace the filter materials. Therefore, it is necessary to improve the existing technology.

[0036] Therefore, in order to solve the above technical problems, the embodiment of the present application provides a rotary filter, which can realize different filter materials by rotating according to different filtering requirements and can perform multi-stage filtration.

[0037] The present invention is described in detail below with reference to the accompanying drawings.

[0038] See also Figures 1 to 4 .

[0039] The rotary filter of the embodiment of the present application includes several hollow filter housings 1 distributed and connected in the vertical direction, several filter boxes 2 arranged in the filter housings 1, and a positioning structure. A rotating chassis 3 is provided in the filter housing 1, and the filter boxes 2 are distributed circumferentially on the rotating chassis 3. The filter boxes 2 include filter boxes 2 with different filter materials and blank filter boxes 2.

[0040] The hollow filter housing 1 of the embodiment of the present application can be exemplarily configured as a cylindrical shape. The material of the filter housing 1 is not limited in the embodiment of the present application and can be prepared according to actual application.

[0041] The filter box 2 includes a filter box 2 provided with different filter materials. The filter material in each filter box 2 can be a single type of different filter material, thereby constituting a filter box 2 with different filter materials, or different types of filter materials can be placed in the same filter box 2. The specific implementation method is set according to the actual application.

[0042] The blank filter box 2 in the embodiment of the present application refers to a hollow filter box 2 without any filter material added.

[0043] A filter channel 4 is provided in the filter housing 1 , a water inlet 41 is provided at the top of the filter channel 4 , and a water outlet 42 is provided at the bottom of the filter channel 4 . The filter box 2 can be rotated and positioned in the filter channel 4 through a positioning structure.

[0044] The rotary filter of the embodiment of the present application includes a plurality of hollow filter housings 1 distributed and connected in a vertical direction. Furthermore, the water outlet 42 of the hollow filter housing 1 is connected to the water inlet 41 of the adjacent hollow filter housing 1 to form a connection between the adjacent hollow filter housings 1.

[0045] The positioning structure of the embodiment of the present application enables the filter box 2 to be accurately positioned in the filter channel 4 to avoid displacement during the rotation process, which would affect the filtering operation.

[0046] The beneficial effects of the embodiments of the present application: The rotary filter can match corresponding filter boxes according to the filtering requirements of different samples to be filtered by setting up several filter boxes that can be rotated to the filtering channel, and then filter different samples to be filtered. The operation is convenient and does not require multiple filtering devices and replacement devices. It can minimize costs and improve filtering effects and filtration efficiency. At the same time, the present application sets up several hollow filter shells distributed and connected in the vertical direction, and several filter boxes arranged in the hollow filter shells. The filter boxes include filter boxes with different filter materials and blank filter boxes (that is, there is no filter material in the filter box). Therefore, multi-stage filtration or multi-stage concentration can be performed according to the filtering requirements. That is, after the first filtration, if no filtration is required again, the filter box below is rotated to a blank filter box to recover the liquid. If further filtration is required, the corresponding filter box below can be rotated to the filter channel for multi-stage filtration or multi-stage concentration, thereby further improving the filtering and concentration effect.

[0047] Example 2

[0048] The above embodiment introduces the structural features and functions that can be achieved by the rotary filter. The present embodiment will further develop an inventive design for the rotary filter of the above embodiment 1.

[0049] The filter rotator of the embodiment of the present application includes the structural features of the embodiment one, including a plurality of hollow filter housings 1 distributed and connected in the vertical direction, a plurality of filter boxes 2 arranged in the hollow filter housing 1 and a positioning structure, a rotating chassis 3 is provided in the filter housing 1, the filter boxes 2 are circumferentially distributed on the rotating chassis 3, the filter boxes 2 include filter boxes 2 with different filter materials and blank filter boxes 2; a filter channel 4 is provided in the filter housing 1, a water inlet 41 is provided at the top of the filter channel 4, and a water outlet 42 is provided at the bottom of the filter channel 4, and the filter box 2 can be rotated and positioned in the filter channel 4 through the positioning structure.

[0050] Furthermore, the positioning structure includes a positioning window 5 and a spring pressure block 6. The positioning window 5 is provided on the circumferential surface of the filter housing 1 constituting the filter channel 4, and the spring pressure block 6 is provided on the box surface of the filter box 2 that is in contact with the circumferential surface of the filter housing 1. That is, when no filter box 2 is correctly positioned in the filter channel 4, the spring pressure blocks 6 of the positioning structure are all retracted into the filter housing 1. A spring pressure block 6 is provided on the circumferential surface of each filter box 2. When the filter box 2 is rotated to the filter channel 4, the spring pressure block 6 passes through the positioning window 5 to prevent the filter box 2 from continuing to rotate, and can accurately position the filter box 2 in the filter channel 4. When the filter box 2 that needs to stay in the filter channel 4 is not correct, the next filter box 2 can be rotated and switched by pressing the spring pressure block 6.

[0051] Furthermore, the spring pressure block 6 includes a spring member and a pressure block, and the pressure block is mounted on the filter box 2 via a spring.

[0052] Furthermore, a gripping block 7 is provided on the top surface of the filter box 2. The gripping block 7 facilitates the operator to hold and rotate the filter box 2 with a force point.

[0053] Furthermore, the bottom of the filtration channel 4 is in an inverted cone shape. The inverted cone structure can better recover the filtrate.

[0054] Furthermore, a socket 31 is provided on the rotating chassis 3 , and the filter box 2 is detachably mounted on the socket 31 .

[0055] Furthermore, the shape of the socket 31 is consistent with the outer contour of the filter cartridge 2, and an annular elastic boss 311 is provided on the inner edge of the socket 31. When the filter cartridge 2 is placed in the socket 31, the elastic boss 311 of the socket 31 can further grip and fix the filter cartridge 2, stabilizing the filter cartridge 2 and preventing the filter cartridge 2 from tipping over or shaking during use of the rotary filter of the present application.

[0056] Furthermore, a plurality of hollow filter housings 1 distributed in a vertical direction are connected in a disassembly manner. This structure allows the number of filter housings 1 to be reduced or increased according to actual application requirements.

[0057] Furthermore, the filter material contained in the filter box 2 includes CA pure acetic acid, RC regenerated cellulose, PES polyethersulfone, modified polyvinylidene fluoride PVDF or SAP water-absorbing particles. The corresponding filter material is added according to different application requirements.

[0058] Furthermore, the filter housing 1 is provided with a transparent observation window 8 at the position corresponding to the filter channel 4. The setting of the observation window 8 facilitates observation of the filtering condition of the filtered sample. Furthermore, in order to facilitate observation of the filtering process, the filter box 2 is preferably made of a transparent material.

[0059] The beneficial effects of the embodiments of the present application are as follows: The positioning structure of the rotary filter includes a positioning window and a spring pressure block. The positioning window is provided on the circumferential surface of the filter housing that forms the filter channel, and the spring pressure block is provided on the surface of the filter cartridge that contacts the circumferential surface of the filter housing. By pressing the spring pressure block, the filter cartridge can be freely rotated to switch to the next filter cartridge. The spring pressure block accurately positions the filter cartridge in the filter channel, and the elastic boss of the socket further secures the filter cartridge, providing a stable position and preventing the filter cartridge from tipping over or shaking during use.

[0060] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures. In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of this application; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0061] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0062] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
