Description

Technical Field

[0001] The utility model belongs to the technical field of glass tube preparation, and in particular relates to a preparation device for medium-borosilicate medicinal glass tubes. Background Art

[0002] As the direct carrier of pharmaceuticals, pharmaceutical packaging materials have an important responsibility for ensuring the quality and safety of drugs. With its characteristics of being smooth, transparent, easy to disinfect, and having good sealing properties, glass has been proven to be the preferred packaging material in the pharmaceutical industry after nearly a hundred years of application and practice. In particular, medium-borosilicate glass has better impact resistance and chemical stability, and has become the internationally recognized safest pharmaceutical packaging material. It is widely used in the packaging of high-end infusions, antibiotics, lyophilized agents, vaccines, biological agents and other pharmaceuticals. The preparation of medium-borosilicate pharmaceutical glass is made by secondary processing of medium-borosilicate glass tubes. The medium-borosilicate tube drawing technology has become the core barrier of medium-borosilicate tube bottles. At present, the mainstream methods of medium-borosilicate tube control are the Dana method and the Vero method. The Vero method has a higher plant building and a larger investment and energy consumption. The Dana method is more widely used. In the Dana method, a homogenization tank is required to clarify the glass liquid.

[0003] At present, in the process of preparing medium-borosilicate pharmaceutical glass tubes using the Dana method, due to the certain viscosity of the glass liquid, a large amount of glass liquid will adhere to the inner wall surface of the homogenization tank during discharge, which leads to a decrease in material utilization and indirectly increases the production cost. Moreover, most homogenization tanks directly discharge the sediment at the bottom after sedimentation, and there is also a certain amount of clarified material in the sediment. Direct discharge will also reduce the utilization rate of the material and increase the production cost. For this reason, we propose a preparation device for medium-borosilicate pharmaceutical glass tubes. Utility Model Content
