Description

Technical Field

[0001] The utility model relates to the technical field of medicines, in particular to a filtering and mixing device for pharmaceutical intermediates. Background Technique

[0002] The filtering and mixing device for pharmaceutical intermediates plays an important role in the pharmaceutical industry. With the development of pharmaceutical technology, the requirements for the purity and quality of pharmaceutical intermediates are increasing day by day, which makes efficient filtering and mixing technologies particularly crucial.

[0003] In the prior art, through retrieval, it is found that the Chinese patent discloses a "filtering and mixing device for pharmaceutical intermediates", and its application number is "202321836404.5". The above patent mainly includes a first bottom plate and a second bottom plate. A toothed ring is arranged outside the mixing barrel. An opening groove is arranged outside the mixing barrel. A first groove and a second groove are respectively arranged on both sides of the opening groove. A filter layer is inserted into the first groove. A number of small filter holes are arranged inside the filter layer. A sealing layer is inserted into the second groove. One end of a spring is fixedly connected to a sieve. A partition is arranged inside the sieve. A number of large filter holes are arranged inside the partition. Although the above utility model solves the drawback of uneven mixing caused by simultaneous filtering and discharging through the combined setting of the sealing layer and the filter layer, where the sealing layer plays a sealing role during mixing and the filter layer does not function, and the filter layer plays a role when the sealing layer is removed during filtering. However, after the raw materials are screened by the sieve, they need to be reloaded into the mixing cylinder through the feeding port. After the screened raw materials are loaded into the mixing cylinder, the filter layer and the sealing layer need to be operated to seal the mixing cylinder before the mixing work can be carried out. The overall operation process is not coordinated and efficient enough, which is not conducive to improving the production efficiency of medicines. Therefore, the utility model provides a filtering and mixing device for pharmaceutical intermediates to solve the problems raised in the above background technique. Summary of the Utility Model

The inner side of the through hole is also movably connected with a filter cartridge 7. The outer diameter of the filter cartridge 7 is slightly smaller than the inner diameter of the through hole, so that the filter cartridge 7 can rotate freely in the through hole. One side of the filter cartridge 7 close to the through hole is provided with an open structure, and the inner wall of the side of the filter cartridge 7 far from the through hole is fixedly connected to the second rotating shaft 6.

[0023] The pharmaceutical intermediate to be filtered is fed into the interior of the filter cartridge 7 through the opening of the filter cartridge 7.
