Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filling equipment, and more specifically, to a kind of aseptic liquid raw material filling equipment. Background Art
[0002] When sterile liquids are being produced and filled, they are all completed in the sterile workshop. When the existing sterile liquid raw material filling equipment is in use, the feed pump and the filling head are generally connected to the raw material barrel. The feed pump and the raw material barrel are connected by a flange. When different raw material barrels need to be replaced, it is not easy to replace, and the disassembly and installation time is long; in addition, when a certain amount of filling needs to be replaced when the receiving container is replaced, the feed pump and the filling head need to be closed synchronously, and part of the liquid will flow back. When the container needs to be replaced and filling needs to continue, the liquid cannot be discharged immediately, and the synchronous closure of the feed pump and the filling head also needs to be linked through the control device. When the linkage fails, it is easy to happen that the filling head has been closed, but the feed pump continues to work, which will cause the pipeline to rupture or the internal results of the feed pump to be damaged.
