Description

TECHNICAL FIELD

[0001] The utility model relates to traditional Chinese medicine processing technical field especially relates to a multistage fine filter screening machine for traditional Chinese medicine decoction pieces. BACKGROUND

[0002] Traditional Chinese medicine decoction pieces are the basis of traditional Chinese medicine preparation, and their quality directly affects the efficacy and safety of drugs. In the processing of traditional Chinese medicinal materials, screening is a crucial link. The main task is to remove impurities, particles that do not meet the specifications, and unqualified materials (such as foreign matter, dust, and debris). This is crucial for ensuring the efficacy of the final medicinal material and the stability of drug quality.

[0003] The existing patent with publication number "CN221472523U" discloses a multistage fine filter screening machine for traditional Chinese medicine decoction pieces, which includes a main tank. The top outer wall of the main tank is provided with a top cover. The top outer wall of the top cover is provided with a top groove. The top outer wall of the top cover is fixedly connected with a first handle at both ends. The bottom of the main tank is provided with a processing tank. The top outer wall of the processing tank is fixedly connected with a third handle at both ends. The utility model drives the processing tank to vibrate through the starting of the driving mechanism, and then drives multiple collection boxes and the filter screens inside them to vibrate. This can perform multistage fine filtering and screening of traditional Chinese medicine decoction pieces. Through the action of the plug and the mounting bracket, the collection boxes can be easily installed or removed. This is beneficial for adjusting the number of times of screening traditional Chinese medicine decoction pieces according to requirements. Through the starting of the exhaust mechanism, the dust in the processing tank can be discharged. Through the starting of the purification mechanism, the dust can be filtered, avoiding the direct discharge of dust affecting the surrounding environment air.

[0004] In the traditional fine filter screening machine, impurities often stick to the filter screen. It is not easy to remove the impurities on the filter screen by knocking the filter screen. Moreover, many impurities will block the holes of the filter screen. The filter screen can only be removed and cleaned, which is troublesome. Traditional Chinese medicine decoction pieces are easy to block in the filter screen and cannot be easily discharged. At the same time, traditional Chinese medicine decoction pieces with certain moisture are easy to absorb moisture and may stick to impurities during screening, which is difficult to remove during the screening process.
