Description

Technical Field

[0001] The utility model relates to a drug liquid filtering technology in biopharmaceuticals, in particular to a mounting structure for mounting a valve and a liquid level meter on a filter. Background Art

[0002] Filtration technology is widely used in the biopharmaceutical industry. Contemporary biopharmaceuticals rely heavily on filters to clarify, purify and sterilize large quantities of continuous materials. In order to enable efficient and orderly production, it is essential that the system as a whole meets the hygienic standards. The discharge valve on the top of the filter is to discharge the air inside the equipment during filtration to prevent overpressure. The level gauge is to monitor whether the liquid in the filter is full. When the liquid level reaches the position of the level gauge, the filter is full of liquid medicine and the filtration efficiency is the highest. At this time, the discharge valve is closed to prevent the liquid medicine from overflowing. Therefore, the level gauge on the top of the filter and the discharge valve must also meet the hygienic standard / 2D, because it may be contaminated by improper cleaning. The existing technology generally installs the level gauge through a machined block, but the threaded fixed level gauge is selected. The thread seal does not meet the hygienic standard. No matter what kind of thread is used and how high the processing accuracy is, it is inevitable that the liquid medicine will penetrate into the thread. The thread is difficult to clean and it is easy to breed bacteria and contaminate the liquid medicine. Utility Model Content
