Description

Technical Field

[0001] The utility model relates to the technical field of closed feeding devices, in particular to a closed feeding device for pharmaceutical preparation. Background Art

[0002] Medicine refers to substances used to prevent, treat, and diagnose human diseases, purposefully regulate human physiological functions, and have prescribed indications or functional indications, usage, and dosage. They include traditional Chinese medicine, chemical medicine, and biological products. During the production of medicines, they need to be carried out in a pharmaceutical workshop. During the production of medicines, multiple treatments need to be performed on the raw materials of the medicines. The relatively fine raw materials of the medicines will produce more dust during the feeding process, which will affect the pharmaceutical effect and endanger the health of the workers. In order to better feed the raw materials of the medicines, a closed feeding device for pharmaceutical preparation is proposed.

[0003] For example, a closed feeding device for a pharmaceutical workshop disclosed in the authorization announcement number CN218144491U includes a feeding tank and a silo, and a feeding pipe is inserted through the top surface of the silo;

[0004] Although it adopts a closed feeding tank and a closed feeding barrel, when feeding, the feeding pipe is plugged into the silo of the equipment, the vacuum pump is started, the first plug valve is closed, and the second plug valve is opened. The vacuum pump extracts the air inside the feeding tank through the exhaust pipe, thereby extracting the air inside the feeding barrel, so that the top opening of the feeding hopper is in a negative pressure state, and the medicinal raw materials are put into the feeding barrel from the feeding hopper. The driving motor drives the auger to rotate, and the medicinal raw materials are transported to the lower barrel and discharged into the feeding tank. Since the top opening of the feeding hopper is in a negative pressure, the external gas is supplemented to enter the feeding hopper, forming an airflow entering the feeding hopper. The airflow brings the dust generated when the medicinal raw materials are fed into the feeding hopper, thereby avoiding dust when the medicinal raw materials are fed, and having a good dust prevention effect.

[0005] However, the problem that the existing closed feeding device is not conducive to convenient reciprocating movement to suck dust and convenient circular rotation to feed pharmaceutical raw materials in sequence during use is not solved, which is not conducive to closed negative pressure feeding of pharmaceutical raw materials, affecting the flexibility of feeding. Summary of the invention
