Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of medicine production and processing, specifically, a solid particle filter for pharmaceutical equipment. BACKGROUND

[0002] As an important part in the medical and pharmaceutical fields, the liquid medicine bears the important mission of treating diseases and protecting health. It is a liquid preparation made of medicine as the main component through a specific solvent and preparation process, and is widely used in various drug delivery methods such as oral, injection, and atomization. The solid particle filter is used for filtering the liquid medicine in the production process. The solid particle filter effectively traps solid particles and impurities in the liquid medicine, thereby ensuring the purity of the liquid medicine.

Manual cleaning is required to clean the solid particles and impurities adhered to the filter mechanism. When manually cleaning the filter mechanism, the cleaning personnel need to directly contact the filter mechanism and the solid particles, impurities, etc. on it. These substances may contain toxic and harmful components, which pose a threat to the health of the cleaning personnel. UTILITY MODEL CONTENT

[0008] In the above scheme, the driving motor drives the rotating shaft to rotate the first transmission wheel, and then drives the second transmission wheel through the belt, so that the sewage suction pipe and the cleaning assembly (including the first scraper and the second scraper) on it start to rotate. This design ensures that the cleaning assembly can comprehensively and efficiently scrape off the solid particles and impurities on the inner bottom wall and the inner side wall of the filtering mechanism.
