In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0050] As an important link in the upstream and downstream of bioprocessing, filtration technology has also received more and more attention. In the actual production process, different types of filtration are required according to different production needs.

[0051] In the prior art, each filtering method corresponds to an independent filtering device. When performing actual work, different filtering devices need to be selected according to different filtering needs. This not only causes the installation space occupied by multiple filtering devices to be too large, but also requires workers to switch between various devices, resulting in poor flexibility in use, increased workload on workers, and increased manufacturing costs.

[0052] In order to solve the above problems, Figures 1 to 10 As shown, this embodiment provides a filtering system 1000. The filtering system 1000 includes a first driving member 100, a detachable connecting pipeline 200, a filtering device 300, and a material storage device 600 for storing materials, wherein the filtering system 1000 includes a first connection state and a second connection state. In the first connection state, the connecting pipeline 200 sequentially connects the material storage device 600, the first driving member 100, and the filtering device 300 to form a one-way filtering pipeline, and the material flows out of the filtering system 1000 after being filtered by the filtering device 300; in the second connection state, the connecting pipeline 200 sequentially connects the material storage device 600, the first driving member 100, and the filtering device 300 to form a circulating filtering pipeline, and the material circulates through the filtering device 300 for filtering.

[0053] The filtering system 1000 sequentially connects the material storage device 600, the first driving member 100 and the filtering device 300 in sequence by using a detachable connecting pipeline 200 to form a one-way filtering pipeline, and puts the filtering system 1000 in a first connection state, so that the material is filtered by the filtering device 300 in the first connection state and then flows out of the filtering system 1000, which can achieve one-way filtering of the material and meet various filtering requirements with one-way filtering requirements; by using the detachable connecting pipeline 200, the material storage device 600, the first driving member 100 and the filtering device 300 form a circulating filtering pipeline, and puts the filtering system 1000 in a second connection state, so that the material is circulated through the filtering device 300 for filtering, which can achieve circulating filtering of the material and meet various filtering requirements with circulating filtering requirements, so that the filtering system 1000 is compatible with ultrafiltration, microfiltration, nanofiltration, reverse osmosis filtration, deep filtration and virus removal filtration and other filtering functions at the same time, without using filtering equipment corresponding to various filtering functions for filtering, easy to assemble, high flexibility in use, reduced equipment cost, and improved filtering efficiency.

[0054] In addition, the filter device 300 includes but is not limited to at least one of an ultrafilter, a microfilter, a nanofilter, a reverse osmosis filter, a deep filter, and a virus removal filter. When the filter system 1000 is in a first connection state and the filter device 300 is a deep filter or a virus removal filter, deep filtration or virus removal filtration of the material can be achieved; when the filter system 1000 is in a second connection state and the filter device 300 is an ultrafilter, a microfilter or a reverse osmosis filter, ultrafiltration, microfiltration or reverse osmosis filtration of the material can be achieved, so that the filter system 1000 is compatible with ultrafiltration, microfiltration, nanofiltration, reverse osmosis filtration, deep filtration and virus removal filtration and other filtration functions. It can be understood that those skilled in the art can adjust the specific connection state of the filter system 1000 and the specific type of the filter device 300 according to actual filtering needs.

[0055] Further, the storage device 600 includes a first storage section 610 and a second storage section 620. In the first connection state and the second connection state, at least one of the first storage section 610 and the second storage section 620 is connected to the filtering device 300, so that the material stored in at least one of the first storage section 610 and the second storage section 620 is filtered through the filtering device 300.

[0056] When the filtration system 1000 is in the first connection state, the first material storage part 610 and the second material storage part 620 are both connected to the filtration device 300, so that the material to be filtered in the first material storage part 610 and the auxiliary material in the second material storage part 620 are both filtered unidirectionally through the filtration device 300. At this time, the filtration device 300 can be adjusted to a deep filter, a virus removal filter or other filter that needs unidirectional filtration according to actual filtration requirements.

[0057] As an optional embodiment, the filtration system 1000 further includes a feeding device 500 , which is connected to the first material storage portion 610 , and the feeding device 500 is used to supplement auxiliary materials into the first material storage portion 610 .

[0058] When the filtration system 1000 is in the second connection state, the first material storage part 610 is connected to the filtration device 300, and the second material storage part 620 is not connected to the filtration device 300, so that the material to be filtered in the first material storage part 610 is circulated through the filtration device 300 for filtration, and at the same time, the feeding device 500 replenishes auxiliary materials into the first material storage part 610 to ensure the cyclic filtration of the material to be filtered in the first material storage part 610. At this time, the filtration device 300 can be adjusted to an ultrafilter, a microfilter, a reverse osmosis filter, or other filters that need to be circulated and filtered according to actual filtering requirements.

[0059] Specifically, the feeding device 500 includes a second driving member 510 and a third material storage section 520. The output end of the second driving member 510 is connected to the first material storage section 610, and the input end of the second driving member 510 is connected to the third material storage section 520. Auxiliary materials are stored in the third material storage section 520. The second driving member 510 can transport the auxiliary materials in the third material storage section 520 to the first material storage section 610.

[0060] It should be noted that the first material storage section 610 is used to store material to be filtered, and the second material storage section 620 is used to store auxiliary materials. In the present embodiment, the material to be filtered is a protein solution that needs to be filtered, and the auxiliary material is water for injection, so as to improve buffering for the filtration of the protein solution. In other embodiments, the specific composition of the material to be filtered and the auxiliary material can also be adjusted according to actual needs, and the present embodiment is not specifically limited. As an optional scheme, the connecting pipeline 200 and the first driving member 100 are both disposables. After completing the filtration of the material to be filtered once, the used connecting pipeline 200 and the first driving member 100 can be directly removed from the filtration system 1000, and then a new connecting pipeline 200 and the first driving member 100 are installed according to actual needs, without the need for cleaning verification, and the use-and-disposal is improved, and the filtration efficiency is improved.

[0061] In addition, when replacing the connecting pipe 200, the diameter of the connecting pipe 200 can be adjusted according to actual needs to meet the actual filtering rate requirements, thereby further improving the flexibility of use.

[0062] Specifically, if Figure 1 to Figure 5As shown, when the filtration system 1000 is in the first state, two feed valves 210 are arranged on the connecting pipeline 200, and the two feed valves 210 are respectively arranged between the first storage part 610 containing the material to be filtered and the first driving member 100, and between the second storage part 620 containing the auxiliary material and the first driving member 100. The feed valve 210 is used to control the conduction and isolation between the corresponding first storage part 610 and the first driving member 100, and to control the conduction and isolation between the corresponding second storage part 620 and the first driving member 100. By respectively arranging the feed valve 210 between the first material storage section 610 and the first driving member 100 and between the second material storage section 620 and the first driving member 100, before performing the filtering operation, the feed valve 210 corresponding to the second material storage section 620 containing the auxiliary material can be opened first, so that the auxiliary material can flow through the connecting pipe 200 and the filtering device 300 under the drive of the first driving member 100, thereby rinsing the connecting pipe 200 and the filtering device 300 and ensuring the subsequent filtering effect on the material to be filtered.

[0063] Furthermore, when the filtration system 1000 is in the first state, the connecting pipeline 200 is provided with a first discharge pipe 1 and a second discharge pipe 2, and the finished material to be filtered after being filtered by the filtering device 300 is discharged along the first discharge pipe 1, and the waste solution generated during the filtration process is discharged along the second discharge pipe 2. By providing the first discharge pipe 1 and the second discharge pipe 2 at the discharge point of the connecting pipeline 200, the finished solution and the waste solution can be isolated, and the filtering effect when the subsequent filtered finished liquid is discharged along the first discharge pipe 1 is further ensured.

[0064] In this embodiment, a first discharge valve 220 is provided on the first discharge pipe 1, and the first discharge valve 220 is used to control the conduction, isolation and opening of the first discharge pipe 1. A second discharge valve 230 is provided on the second discharge pipe 2, and the second discharge valve 230 is used to control the conduction and isolation of the second discharge pipe 2. By respectively arranging the first discharge valve 220 on the first discharge pipe 1 and the second discharge valve 230 on the second discharge pipe 2, when a rinsing operation is performed before filtering, the first feed valve 210 and the second discharge valve 230 corresponding to the second storage section 620 containing auxiliary materials are opened, and the first discharge valve 220 is closed to allow the auxiliary materials to flow through the connecting pipeline 200 and the filtering device 300 and then be discharged along the second discharge pipe 2 to complete the rinsing, and then the second discharge valve 230 is closed. At the same time, the first feed valve 210 and the first discharge valve 220 corresponding to the first storage section 610 containing the material to be filtered are opened to allow the material to be filtered to enter the filtering device 300 along the connecting pipeline 200 for filtration and be discharged along the first discharge pipe 1.

[0065] It should be noted that, in the present embodiment, both the first discharge valve 220 and the second discharge valve 230 are provided with a receiving groove, and the connecting pipeline 200 is overlapped and fixed on the corresponding receiving groove, so as to fix the connecting pipeline 200 while controlling the conduction and blocking in the connecting pipeline 200. In addition, in the present embodiment, the first discharge valve 220 is a proportional valve, and the second discharge valve 230 is a switch valve. Compared with the switch valve, the proportional valve can adjust the degree of conduction, thereby facilitating the adjustment of the discharge rate of the finished filtered material along the first discharge pipe 1. In other embodiments, the second discharge valve 230 can also be set as a proportional valve, which is not specifically limited in the present embodiment.

[0066] like Figure 5 As shown, when it is necessary to perform unidirectional filtration on the material to be filtered, first open the first feed valve 210 and the second discharge valve 230 corresponding to the second storage part 620 containing the auxiliary material, close the first discharge valve 220, so that the first drive member 100 drives the auxiliary material to flow through the connecting pipeline 200 and the filtering device 300 and then be discharged along the second discharge pipe 2 to complete the rinsing; then open the first feed valve 210 and the first discharge valve 220 corresponding to the first storage part 610 containing the material to be filtered, so that the first drive member 100 simultaneously drives the material to be filtered in the first storage part 610 and the auxiliary material in the second storage part 620 to enter the filtering device 300 along the connecting pipeline 200, so that the filtering device 300 filters the material to be filtered. After the filtering device 300 completes the filtration of the material to be filtered, the finished material to be filtered produced after the filtration will be discharged along the first discharge pipe 1, and the waste solution produced by the filtration will be discharged along the second discharge pipe 2, thereby achieving unidirectional filtration of the material to be filtered.

[0067] Combination Figure 6 to Figure 10 The filtration system 1000 in the second state is analyzed. When the filtration system 1000 is in the second state, the connecting pipeline 200 will close the loop of the first storage part 610 containing the material to be filtered, the first driving member 100 and the filtration device 300 at the detachable connection. The third discharge pipe 3 is arranged on the connecting pipeline 200, and the first storage part 610 is connected to the feeding device 500. The filtered solution generated during the filtration process is discharged along the third discharge pipe 3.

[0068] When the connecting pipeline 200 and the filter device 300 need to be rinsed before filtering, due to the filtering characteristics of ultrafiltration, the first driving member 100 can directly drive the material to be filtered in the first storage part 610 to be rinsed, and the rinsed liquid circulates and flows in the closed loop composed of the first storage part 610 containing the material to be filtered, the first driving member 100 and the filter device 300. When the material to be filtered is ultrafiltered, due to the filtering characteristics of ultrafiltration, the filtered solution produced by ultrafiltration is discharged along the third discharge pipe 3, and the material to be filtered after ultrafiltration is returned to the first storage part 610 along the connecting pipeline 200 for cyclic filtration. At the same time, the second driving member 510 in the feeding device 500 drives the auxiliary material in the third storage part 520 to enter the first storage part 610 for cyclic filtration.

[0069] In addition, a first discharge valve 220 is arranged on the return pipeline between the filtering device 300 and the first material storage part 610. The first discharge valve 220 in the second state is used to control the conduction, isolation and opening of the return pipeline, so as to facilitate the staff to control the start, shutdown and flow rate of the filtering cycle of the material to be filtered.

[0070] As an optional solution, the filtration system 1000 further includes a flow detection device 400, wherein the flow detection device 400 is used to detect the flow of the material to be filtered after filtration in the connecting pipeline 200, so that the staff can record the filtration rate. It should be noted that in this embodiment, when the filtration system 1000 is in the first state, the flow detection device 400 is arranged on the first discharge pipe 1; when the filtration system 1000 is in the second state, the flow detection device 400 is arranged between the third discharge pipe 3 and the return pipe between the filtration device 300 and the first storage part 610.

[0071] Specifically, the flow detection device 400 is a photoelectric sensor or an ultrasonic sensor, and a tube clamp is provided inside the flow detection device 400. The first discharge pipe 1, the third discharge pipe 3 or the return pipe is passed through the tube clamp to facilitate the flow detection device 400 to detect the liquid flow in the first discharge pipe 1, the third discharge pipe 3 or the return pipe.

[0072] Furthermore, the filtration system 1000 also includes an integrated control cabinet 700, wherein the first drive member 100, the connecting pipeline 200 and the feeding device 500 are all installed on the integrated control cabinet 700. The integrated control cabinet 700 can individually control the start and stop of the first drive member 100, the two feed valves 210, the first discharge valve 220, the second discharge valve 230 and the filtration device 300 in the filtration system 1000 to adjust the filtration function according to the actual state.

[0073] To further improve the fixing effect of the connecting pipe 200, as Figure 1 to Figure 4As shown, a pipeline fixing part 710 is also provided on the outer peripheral wall of the integrated control cabinet 700 , and a clamping groove is provided on the pipeline fixing part 710 , and the connecting pipeline 200 is clamped and fixed with the clamping groove.

[0074] In this embodiment, the filtration system 1000 further includes a touch screen 800, wherein the touch screen 800 is connected to the integrated control cabinet 700 by signal, and the touch screen 800 can control the start and stop of the components in the integrated control cabinet 700. By setting the touch screen 800 to control the start and stop of the components in the integrated control cabinet 700, it is convenient for the staff to control the overall filtration process and improve the filtration efficiency. It should be noted that the specific structures of the touch screen 800 and the integrated control cabinet 700 and the control principles of each other belong to the prior art and will not be described in detail here.

[0075] As an optional solution, the filtration system 1000 further includes a weighing device 900, wherein the first storage part 610, the second storage part 620 and the third storage part 520 are all provided corresponding to a weighing device 900, and the weighing device 900 is configured to weigh the weight of the corresponding first storage part 610, the second storage part 620 or the third storage part 520. By weighing the weight of the first storage part 610, the second storage part 620 and the third storage part 520, as the filtration continues, the weight of the first storage part 610, the second storage part 620 and the third storage part 520 gradually decreases, and the weight of the material to be filtered and the auxiliary material actually filtered is obtained through the difference between the weights of the first storage part 610, the second storage part 620 and the third storage part 520. It should be noted that, in this embodiment, the weighing device 900 includes a hanging bracket and a weight sensor, the weight sensor is installed on the hanging bracket, the first material storage section 610, the second material storage section 620 and the third material storage section 520 are respectively suspended on the corresponding weight sensors, and the weight of the first material storage section 610, the second material storage section 620 or the third material storage section 520 is detected by the weight sensor.

[0076] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
