Description

Technical Field

[0002] In the production process of Qinqiao oral liquid, in order to improve the clarity of the product and eliminate the product precipitation process, it is necessary to control the clarity of the drug according to the properties of the drug solution itself. The clarification and filtration method directly affects the product quality.

[0003] In the prior art, clarification filtration usually adopts the method of sedimentation and centrifugation. Due to incomplete sedimentation and centrifugation, precipitation is generated in the finished product as the storage period increases.

[0050] In summary, when the overall device is in use or running:

[0051] When the device is used to extract clarified liquid medicine, the outflow of the liquid medicine in the liquid preparation tank 2 is controlled by the first liquid medicine valve 21, the first liquid medicine valve 21 and the second liquid medicine valve 22 are connected to connect the liquid preparation tank 2 with the filter tank 1, and the pressure is provided by the high-pressure infusion pump 35 to input the liquid medicine in the liquid preparation tank 2 into the filter tank 1, so that the liquid medicine flows into the first filter chamber 4 for filtration, and is filtered through the first filter 7. When filtering in the first filter chamber 4, the stirring motor 40 is started, and the stirring paddle 41 is driven by the stirring motor 40 to rotate, so that the liquid medicine in the first filter chamber 4 is stirred, so that the internal substances are evenly distributed, and the filtering speed is increased. After filtration, the impurities in the liquid medicine remain on the first filter 7, and the liquid medicine passes through the filter and falls to the lower end of the first filter chamber 4, and then The third liquid medicine valve 24 and the fourth liquid medicine valve 25 are opened to allow the filtered liquid medicine in the first filter chamber 4 to flow into the upper part of the second filter chamber 5, and then be filtered through the second filter 8. The fifth liquid medicine valve 26 and the sixth liquid medicine valve 27 are opened to allow the filtered liquid medicine in the second filter chamber 5 to flow into the upper part of the third filter chamber 6, and be filtered through the third filter 9. After all the filtering is completed, the filtrate valve 23 is connected to control the liquid medicine in the third filter chamber 6 to flow out of the filter tank 1 through the filtrate valve 23, and the liquid medicine flowing out of the filter tank 1 is introduced into the clarified liquid storage tank 3 through the pressure provided by the circulating pump 36 to complete the extraction of the clarified liquid. In this operation, the filtration apertures of the first filter 7, the second filter 8 and the third filter 9 are gradually reduced.

[0052] In addition to this extraction method, the fifth liquid medicine valve 26 can also be closed, and the third liquid medicine valve 24, the fourth liquid medicine valve 25, the sixth liquid medicine valve 27 and the diverting liquid medicine valve 28 can be connected, so that the third liquid medicine valve 24 is connected to the sixth liquid medicine valve 27 through the diverting liquid medicine valve 28. The liquid medicine filtered in the first filter chamber 4 flows out of the third liquid medicine valve 24 and is diverted. A part of it continues to flow into the second filter chamber 5 along the fourth filter valve for filtration, while the other part directly flows into the third filter chamber 6 for filtration through the conduction of the diverting liquid medicine valve 28 and the sixth liquid medicine valve 27. After the filtration is completed, the diversion liquid medicine valve 28 and the sixth liquid medicine valve 27 are closed, and the fifth liquid medicine valve 26, the converging liquid medicine valve 29 and the converging liquid medicine valve 30 are connected, so that the filtered liquid medicine in the second filter chamber 5 flows out from the fifth liquid medicine valve 26, passes through the converging liquid medicine valve 30 and the converging liquid medicine valve 29, flows into the third filter chamber 6, bypasses the third filter 9, and directly converges with the filtered liquid medicine to be discharged from the filtered liquid valve 23. In this operation, the filtration pore size of the second filter 8 and the third filter 9 is the same, and the previous filtration method is switched to adapt to different filtration needs.

[0053] When filtering, the device is coordinated with the external compressed air supply device, and the compressed air is the compressed air that can directly contact the medicine solution after sterilization and filtration. The first compressed air valve 12, the second compressed air valve 13 and the third compressed air valve 14 are opened, and the first compressed air valve 12 is used to pressurize the first filter chamber 4, and the second compressed air valve 13 is used to pressurize the second filter chamber 5, and the third compressed air valve 14 is used to pressurize the third filter chamber 6, so as to change the permeability of the solution and control the filtration rate. By observing the values ​​of the first pressure gauge 37, the second pressure gauge 38 and the third pressure gauge 39, the pressure conditions in the first filter chamber 4, the second filter chamber 5 and the third filter chamber 6 are judged, and the current is controlled by the control power supply 34. The first ammeter 31, the second ammeter 32 and the third ammeter 33 are connected to the first filter 7 respectively. The motor plate net in the second filter 8 and the third filter 9 is controlled, and the polarity of the input is changed through the cooperation of the electrode net 43, the nano-conductive particles 44 and the ceramic powder 45, so as to operate the polarity of the first filter 7, the second filter 8 and the third filter 9, so as to make the filter charged and adsorb impurities to achieve the purpose of clarifying the liquid medicine, adsorb the negatively charged impurities in the solution, and then filter with the filtering effect of the mixed filter layer 11, and adjust the polarity of the filter structure and the pressure in the filter chamber structure so that the impurity molecules such as protein and tannic acid in the liquid medicine are adsorbed and electrically neutralized during the filtration of the liquid medicine, so that the filtrate is clarified and the filtering effect is improved. When the filtered liquid medicine flows out of the filter tank 1, the state of the liquid medicine flowing out of the first filter chamber 4, the second filter chamber 5 and the third filter chamber 6 is observed by the corresponding turbidity meter 42 to judge the degree of filtration.

[0054] After the filtering operation is completed, the first compressed air valve 12, the second compressed air valve 13 and the third compressed air valve 14 are closed, the fourth compressed air valve 15, the fifth compressed air valve 16 and the sixth compressed air valve 17 are opened, and the first slag discharge port valve 18, the second slag discharge port valve 19 and the third slag discharge port valve 20 are opened, and the first filter chamber 4 is pressurized through the fourth compressed air valve 15, and the pressure will pressurize the first filter 7 from the bottom of the first filter 7, and the second filter chamber 5 is pressurized through the fifth compressed air valve 16, and the pressure will pressurize the second filter chamber 5 from the second filter chamber 5. The second filter 8 is pressurized from below the filter 8, and the third filter chamber 6 is pressurized through the sixth compressed air valve 17. The pressure will pressurize the third filter 9 from below the third filter 9, and cooperate with the polarity control of the motor plate net to make the impurity molecules originally adsorbed and electrically neutralized desorbed, and under the backblowing effect of the pressure below, the impurity precipitate is separated from the corresponding first filter 7, the second filter 8 and the third filter 9, and discharged through the first slag discharge port valve 18, the second slag discharge port valve 19 and the third slag discharge port valve 20 respectively, so as to achieve the purpose of cleaning the filter plate.

In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
