Abstract
Description
Technical Field
[0001] This utility model belongs to the field of liquid preparation and mixing technology, and particularly relates to a liquid preparation and mixing device. Background Technology
[0002] Liquid mixing is mainly used in the process of mixing medicines. Usually, powder and liquid are added to the mixing tank through mixing equipment. Combined with the mixing tank's own stirring and homogenization, the medicine is fully mixed to form the medicine components. The medicine components are then sent to the storage tank by the delivery pump, and the storage tank completes the metering output to facilitate subsequent filling operations.
[0003] During the conversion process, it is necessary to clean the mixing tank and storage tank to reduce the impact of previous drug residues on the subsequent mixing process. Currently, most cleaning for the mixing process is done by rinsing. During the rinsing process, the cleaning fluid is usually discharged directly without being reused. However, when rinsing stubborn impurities in the tank, a large amount of cleaning fluid is required for cleaning. In this process, no circulation method is used to reduce the amount of cleaning fluid used, resulting in a large waste of cleaning fluid. Utility Model Content

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0019] This utility model embodiment provides a liquid mixing device, such as... Figure 1 As shown, the liquid mixing device includes:
[0020] The system includes a mixing tank 101 and a storage tank 102, with a transfer pump 210 between them. The storage tank 102 is equipped with a metering pump 220 for discharging the liquid medicine. The mixing tank 101 also has a powder mixing device at its front end and a heating and cooling device on its side wall. The mixing tank 101 is internally equipped with various level, temperature, and concentration sensors, as well as a stirring device. The structure and auxiliary structures of the mixing tank 101 are based on existing liquid mixing equipment used in chemical and pharmaceutical processes, and will not be described in detail here. After the liquid medicine is prepared in the mixing tank 101, it is transported to the storage tank 102 for storage via the transfer pump 210. The metering pump 220 meteres and outputs the liquid medicine from the storage tank 102 for subsequent filling.
[0021] The cleaning pipeline includes a purified water pipeline 110 and a return pipeline 120. The purified water pipeline 110 is provided with a first branch 111 and a second branch 112, which are respectively connected to the spray heads provided on the liquid preparation tank 101 and the liquid storage tank 102. One end of the return pipeline 120 is connected to a sewage discharge pipeline provided on the liquid storage tank 102, and the other end is connected to the first branch 111. The pipeline connecting the transfer pump 210 and the liquid storage tank 102 is also provided with a third branch 113, which is connected to the second branch 112.
[0022] The sewage discharge pipeline is equipped with a sewage pump 230. During the cleaning process, the cleaning solution delivered from the purified water pipeline 110 to the first branch 111 first enters the mixing tank 101 by spraying. Then, the transfer pump 210 located between the mixing tank 101 and the storage tank 102 delivers the solution to the second branch 112. The second branch 112 then sprays the solution back into the storage tank 102 for secondary cleaning. Subsequently, the return pipeline 120, in conjunction with the sewage discharge pipeline, returns the cleaning solution in the storage tank 102 back to the first branch. 111, and put it back into the mixing tank 101. By recycling the cleaning solution, the inside of the mixing tank 101 and the storage tank 102 is flushed, reducing the loss of cleaning solution during the flushing process. The spray head provided in the mixing tank 101 and the storage tank 102 is a high-pressure spray head. The repeated flushing of stubborn impurities by the reused cleaning solution reduces the adhesion of impurities inside the mixing tank 101 and the storage tank 102. Since the flushing process uses circulating cleaning solution, a large amount of cleaning solution is not wasted during the flushing process.
[0023] The bottom of the mixing tank 101 is equipped with a mixing and drain pipe, which is connected to the drain pipe. After the flushing process is completed, the mixing and drain pipe and the drain pipe send out the cleaning solution from the flushing process. Then, the drain pump 230 and the return pipe 120 are turned off to return to the reflux state. The purified water pipe 110 is cleaned independently through the first branch 111 and the second branch 112. The delivery pump 210 is still turned on, but the connection with the third branch 113 is disconnected. The pipe between the mixing tank 101 and the storage tank 102 is cleaned by circulating the cleaning solution. The mixing and drain pipe at the bottom of the mixing tank 101 helps to discharge the cleaning solution in the mixing tank 101. Similarly, the drain pipe of the storage tank 102 is turned on at the same time to send out the cleaning solution.
[0024] In a preferred embodiment of this invention, the purified water pipeline 110 is provided with a first three-way valve 301 and a second three-way valve 302. One end of the first three-way valve 301 is the water inlet end, and the first three-way valve 301 is also connected to the second three-way valve 302. The remaining end of the first three-way valve 301 is connected to the first branch 111. The end of the second three-way valve 302 that is connected to the first three-way valve 301 serves as the water inlet end of the second three-way valve 302. The other two ends of the second three-way valve 302 are respectively connected to the second branch 112 and the third branch 113.
[0025] The sewage discharge pipeline is equipped with a sewage pump 230 and a fourth three-way valve 402. The return pipeline 120 is connected to the fourth three-way valve 402. The pipeline connecting the delivery pump 210 and the storage tank 102 is equipped with a third three-way valve 401. The third three-way valve 401 is located at the connection between the third branch 113 and the pipeline connecting the delivery pump 210 and the storage tank 102.
[0026] The sewage pump 230 is located at the front end of the fourth three-way valve 402, and the delivery pump 210 is located at the front end of the third three-way valve 401.
[0027] During the flushing process, the first three-way valve 301 first disconnects from the second valve 302, and then completely closes after adding a certain amount of cleaning fluid to the liquid preparation tank 101. Meanwhile, the sewage pump 230 and the transfer pump 210 are turned on simultaneously. The second valve 302 connects the third branch 113 with the second branch 112. The third three-way valve 401 allows the transfer pump 210 to deliver liquid to the third branch 113 instead of directly entering the liquid storage tank 102. The fourth three-way valve 402 allows the sewage pump 230 to deliver the cleaning fluid to the first branch 111 and then put it back into the liquid preparation tank 101. The circulating cleaning fluid is used to repeatedly flush away impurities.
[0028] After the impurities are flushed out, the first three-way valve 301 opens and connects with the second three-way valve 302, simultaneously supplying liquid to the first branch 111 and the second three-way valve 302. The second three-way valve 302 simultaneously connects the second branch 112 with the purified water pipeline 110. The third three-way valve 401 closes the delivery pump 210, and the liquid is delivered to the delivery channel of the third branch 113. The fourth three-way valve 402 disconnects the sewage pipeline from the return pipeline, and both the sewage pipeline and the liquid preparation and sewage pipeline discharge cleaning liquid outwards.
[0029] In this embodiment, the first branch 111 is equipped with a one-way valve. The one-way valve of the first branch 111 is arranged near the purified water pipeline 110 to avoid backflow contamination of the purified water quality of the main pipeline. The first three-way valve 301, the second three-way valve 302, the third three-way valve 401 and the fourth three-way valve 402 are all solenoid valves.
