Description

Technical Field

[0001] This utility model relates to the field of membrane separation device technology, specifically a fermentation broth membrane separation device. Background Technology

[0002] A fermentation broth membrane separation device is an advanced piece of equipment used for the post-processing of fermentation broth. It efficiently separates, concentrates, or purifies different components (such as cells, proteins, and metabolites) in the fermentation broth using selective separation membranes. Its core principle is to achieve molecular-level sieving by utilizing membrane pore size or selective permeability.

[0003] The prior art patent document CN221608070U provides an Escherichia coli fermentation liquid membrane separation device, comprising: a mounting frame, a support rod, an inlet pipe, and an outlet pipe. Connecting pipes are spaced apart on the outer surfaces of both the inlet and outlet pipes, and valves are installed on the connecting pipes. A connecting plate is installed between the inlet and outlet pipes, and a positioning groove is provided on one side of the connecting plate. A filter pipe is installed inside the positioning groove, and conveying pipes are respectively installed at both ends of the filter pipe. The device also includes a foldable flexible hose, one end of which is sealed to one end of the connecting pipe, and the other end of which is threaded to the conveying pipe. This device allows any filter pipe to be individually removed from the separation device via the positioning groove, flexible hose, and valves, facilitating replacement and maintenance without affecting the normal use of other filter pipes, ensuring continuous production and good performance.

[0004] Although the device has many beneficial effects, it still has the following problems: During use, due to the lack of a storage device, when adding fermentation liquid, the staff needs to open the cover and put the fermentation liquid to be processed into the separation equipment. Each separation unit needs to add fermentation liquid after processing. When a large amount of fermentation liquid needs to be processed, the feeding process takes too much time, which reduces the efficiency of processing fermentation liquid. In addition, when the separation unit needs to be cleaned, a cleaning solution needs to be added to clean the inner wall of the separation unit. The wastewater generated after cleaning is not convenient to be discharged directly. The staff needs to use special tools to drain the wastewater, which is cumbersome and inconvenient for cleaning. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the aforementioned issues during the operation of this device, due to the lack of a storage device, when adding fermentation liquid, workers need to open the cover and add the fermentation liquid to be processed into the separation equipment. This process is repeated after each separation unit has finished processing, and when processing large quantities of fermentation liquid, the feeding process takes up too much time, leading to decreased processing efficiency. Furthermore, when the separation unit needs cleaning, cleaning fluid needs to be added to clean the inner walls. The resulting wastewater is difficult to drain directly and requires workers to use specialized tools for drainage, making wastewater discharge cumbersome and cleaning inconvenient.

[0008] Therefore, the purpose of this utility model is to provide a fermentation liquid membrane separation device. An installation ring can be installed on the surface of the separation device, and a support frame is fixedly connected to the surface of the installation ring. A stabilizing plate, which is fixedly connected to a storage tank, is fixedly connected to the top of the support frame. The fermentation liquid to be treated is pre-filled into the storage tank, temporarily storing it inside. After the fermentation liquid inside the separation device is processed, a second water pump can be started to draw the fermentation liquid from the storage tank into the separation device. Once the area to be treated inside the separation device is filled, the second water pump can be stopped to prevent excessive fermentation liquid inside the separation device. Simultaneously, after the separation process is completed, the inside of the separation device needs to be cleaned. During cleaning, a cleaning solution is added inside the cleaning device. After cleaning, the drain pipe can be opened, and the cleaned wastewater will flow directly into the wastewater tank through the drain pipe fixedly connected to the bottom of the separation device. This eliminates the need for personnel to clean the residual wastewater inside the separation device, making cleaning more convenient.

[0043] Combination Figures 1-5 The specific usage process of the fermentation liquid membrane separation device of this embodiment is as follows:

[0044] 1: When using this fermentation liquid membrane separation device, the device first needs to be placed in the required position. The device can be placed stably in the required position by the cooperation of the legs 2 fixedly connected to the bottom four corners of the middle plate 1 and the internal bottom frame 17. The device has good stability.

[0045] 2: After placement, it can be used. First, the fermentation liquid to be processed needs to be put into the storage tank 28 of the device. If there is too much fermentation liquid, it can be processed in batches. When adding, you can observe the liquid level gauge 30 on the front of the storage tank 28 to prevent overflow due to excessive fermentation liquid. After adding, close the injection port 29, and then you can start the device. The second water pump 31 is started through the control module 11, so that the second water pump 31 can draw fermentation liquid from the storage tank 28 and transport it into the separation device 12. Each time, a certain amount of fermentation liquid can be drawn out by the water pump. After a batch of fermentation liquid is processed, the second water pump 31 can be turned on again to continue to draw fermentation liquid from the storage tank 28. There is no need for the staff to open the cover 32 to manually add the material. Just add the fermentation liquid into the storage tank 28 in a concentrated manner, which reduces the feeding frequency of the staff and eliminates the need for additional opening operations, thus speeding up the separation efficiency of the separation device 12.

[0046] 3. After the entire separation process is completed, in order to facilitate changing the type of fermentation liquid or preparing the fermentation liquid for the next process, it is necessary to clean the inner wall of the separation device 12. When cleaning the separation device 12, the installation ring 25 and the cover plate 32 need to be removed first, the separation device 12 is opened, and then cleaning liquid or other cleaning liquid is injected into the separation device 12. After the inside is cleaned, the drain pipe 18 at the bottom of the separation device 12 can be opened through the control module 11 to drain the wastewater inside the separation device 12. Finally, the water droplets remaining on the inner wall of the separation device are cleaned. The drained wastewater will flow directly into the wastewater tank 19 through the drain pipe 18. After the drainage is completed, the wastewater tank 19 can be pulled out by pulling the pull handle 24. After being pulled out, the wastewater can be centrally treated. Cleaning and treating wastewater is relatively convenient.

[0047] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention.
