Technical Field

[0001] The utility model relates to the technical field of oral liquid production, in particular to a filtering device for oral liquid production. Background Technique

[0002] An oral liquid refers to a single-dose packaged mixture, which is a new dosage form developed on the basis of decoctions and injections. Oral liquids have the advantages of small dosage, fast absorption, stable quality, convenient carrying and taking, and easy preservation. They are especially suitable for industrial production. Some varieties are suitable for emergency use in traditional Chinese medicine, such as Sini Decoction Oral Liquid and Yinhuang Oral Liquid. Therefore, in recent years, many tablets, granules, pills, decoctions, traditional Chinese medicine mixtures, injections, etc. have been reformed into oral liquids, making it one of the dosage forms with relatively fast development in pharmaceutical preparations. At present, during the production process of oral liquids, it is necessary to filter the oral liquids to remove large particle impurities and the like contained therein;

[0003] In this regard, the Chinese utility model patent with the authorization announcement number CN215137747U discloses a filtering device for oral liquid production, including a base. On one side of the upper end surface of the base, there are a liquid storage chamber, a circulating filtration chamber support, a first negative pressure pump support, a first negative pressure pump, and a circulating filtration chamber. Hooks and a filter frame are hung on the inner wall of the circulating filtration chamber through bumps. In the middle of the lower end surface of the circulating filtration chamber, a drain pipe is communicated. One end of the first negative pressure pump is communicated with the inside of the drain pipe through a circulating liquid extraction pipe, and the other end of the first negative pressure pump is communicated with the inside of the circulating filtration chamber through a circulating liquid outlet pipe. One end of a liquid infusion pipe is communicated with the liquid storage chamber through one end of a second negative pressure pump. One end of the liquid infusion pipe is fixedly installed with a coarse filtration chamber through a flange, and a liquid delivery pipe is fixedly installed on the upper end surface of the coarse filtration chamber through a flange. In the present utility model, the oral liquid can be precipitated and filtered, the impurity removal efficiency is improved, and the filtering effect is good, which well meets the usage requirements of users;
