Description

Technical Field

[0001] This invention relates to the field of pharmaceutical cleaning machine technology, specifically to a pharmaceutical cleaning machine circulating water connection system. Background Technology

[0002] Pharmaceutical manufacturing involves multiple production equipment and production lines, many of which are in direct contact with drugs. According to national regulations, these parts that come into direct contact with drugs require efficient and stable cleaning processes. However, the cleaning wastewater generated during the cleaning process is complex in composition, with characteristics such as high concentration of organic matter, antibiotic residues, and difficulty in degradation. Moreover, the amount of wastewater generated in a single cleaning cycle is relatively large, resulting in a waste of water resources.

[0003] Currently, most pharmaceutical factories use automatic cleaning machines to clean parts that come into contact with medicines. Cleaning machines from different brands on the market generally use a structure where the cleaning pipeline and the drying pipeline are separate, making it impossible to dry the cleaning pipeline.

[0004] Because the production components involved are diverse, the spraying station cannot be standardized. The components need to be classified and cleaned in batches. When each batch of components is sent into the cleaning machine, the basket carrying the components needs to be connected to the outlet of the circulating cleaning system. Currently, the market generally uses manual connection, which cannot achieve truly sterile operation during the cleaning process. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a circulating water connection system for pharmaceutical cleaning machines, which solves the problems of water waste, inability to dry pipelines, and sterility risks during the cleaning process.
