Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical manufacturing, in particular to a grinding device for raw and auxiliary materials used in drug synthesis. Background Technique

[0002] Drugs are substances used for preventing, treating and diagnosing diseases. In theory, drugs refer to chemical substances that can affect the physiological functions of body organs and cell metabolic activities, and drugs need to be synthesized from different raw materials.

[0003] In the prior art, the Chinese utility model content with the authorization announcement number: CN220386647U discloses a grinding and crushing device for raw materials used in drug synthesis, including a grinding box and a blanking table. Two groups of supporting legs are symmetrically installed at the bottom of the grinding box, and a discharge port is penetrated and opened at the bottom of the grinding box. A fixing plate is fixedly installed inside the grinding box. It also includes: a crushing component is arranged on one side inside and outside the grinding box. Among them, the crushing component includes a rotating shaft rotatably connected to the fixing plate through a bearing. A protective cover is fixedly installed on the top of the fixing plate. The rotating shaft is rotatably connected to the protective cover through a bearing. A first bevel gear is fixedly installed below the outside of the rotating shaft. A conical hammer is fixedly installed on the top of the rotating shaft. When grinding and crushing drug raw materials, the drug raw materials can enter the grinding box evenly, preventing the accumulation of raw materials, and can fully grind the drug raw materials, improving the working quality and working efficiency of grinding drug raw materials.

[0004] The above technical solution crushes the raw materials through a conical hammer for preliminary crushing, and then fully grinds them through a grinding roller. However, only one group of grinding rollers is provided in this device. When the grinding roller grinds the raw material particles, pressure needs to be applied to the raw material particles. When the grinding roller drives the raw material particles downward to contact the filter screen, the filter screen and the grinding roller are used to apply pressure to the raw material particles to continue to break the raw material particles. At the same time, the crushed raw materials are filtered through the filter screen and fall downward. However, the raw materials are easily stuck on the filter screen by extrusion, resulting in blockage of the filter screen, affecting the continuous falling and grinding of the raw materials. The equipment operates normally, but there is no raw material discharged from the discharge port, reducing the grinding efficiency. Content of the Utility Model
