Description

Fully automatic stainless steel ultrafiltration system Technical Field

[0001] This utility model relates to the field of medical and health care, specifically a modified flexible flat toilet for hospital beds. Background Technology

[0002] In the biopharmaceutical field, ultrafiltration technology, with its superior separation, purification, and concentration properties, has become a crucial and indispensable key process. Currently, production-grade stainless steel ultrafiltration systems are typically equipped with a bottom magnetic stirrer as a circulation tank. Magnetic stirring offers the significant advantage of low shear force, effectively preventing localized high or low concentrations, thus ensuring stable and efficient operation of the ultrafiltration process. More importantly, this system possesses a powerful automatic transmembrane pressure (TMP) regulation function. As a core factor affecting ultrafiltration throughput and membrane lifespan, automatic TP regulation can precisely control the pressure based on dynamic changes in feed properties and filtration progress, keeping the ultrafiltration system in optimal operating condition and significantly improving production efficiency and product quality.

[0003] In stark contrast, experimental ultrafiltration currently relies heavily on manual operation. In actual experiments, manually adjusting parameters is not only extremely time-consuming and labor-intensive, but also makes it difficult to guarantee precision and consistency. When scaling up the experimental process for production, manually operated experimental ultrafiltration systems, unable to simulate the stable operation and precise control of automated production systems, often face significant challenges, severely hindering the process from laboratory to scale-up production. Summary of the Invention

[0004] To address the aforementioned problems, the purpose of this invention is to provide a highly automated, fully automatic stainless steel ultrafiltration system.

[0005] The technical solution for realizing this utility model is as follows:

[0006] The fully automatic stainless steel ultrafiltration system includes a circulation tank. A magnetic stirrer is located at the center of the bottom surface of the circulation tank. A weighing module is located on one side of the magnetic stirrer, and the other side is connected to a diaphragm pump via a first flexible hose. The diaphragm pump is connected to the inlet of the ultrafiltration device, and the outlet of the ultrafiltration device is connected to the top surface of the circulation tank. The weighing module includes a supporting base plate, a weighing transmitter is installed in the center of the supporting base plate, and a U-shaped weighing base plate is located above the weighing transmitter. The magnetic stirrer includes a magnetic stirring motor built into a through hole in the center of the weighing base plate, and several strong magnets are evenly distributed on the top surface of the exposed end of the motor.

[0007] A diaphragm valve assembly is installed on the connecting pipe between the diaphragm pump and the ultrafiltration device, and a diaphragm regulating valve assembly is installed on the connecting pipe between the ultrafiltration device and the circulation tank.
