In the technological process of chemical pharmaceutical industry, beverage industry, brewing industry and the like, two different liquids are often mixed according to a certain proportion. Currently, the two liquids are poured into a storage container separately and then stirred. The whole workload is large, the efficiency is low, the two liquids are difficult to be fully mixed, and the two liquids are likely to be separated again in the transportation and transfer process.

the present application is described in further detail below with reference to fig. 1.

As shown in figure 1, coaxial spiral stirring piece 4 that is provided with in the hybrid tube 1, spiral stirring piece 4 rotates to be connected in hybrid tube 1 to make two kinds of liquid that get into hybrid tube 1 produce the helical motion, thereby realize the homogeneous mixing of two kinds of liquid, the simple operation, mixing efficiency are high, have guaranteed the even degree of mixing simultaneously.

As shown in fig. 1, the flow control assembly 3 includes an inlet pipe 31 and a liquid flow monitor 32, the inlet pipe 31 is disposed on the inlet and is communicated with the infusion tube 2. The liquid flow monitor 32 is arranged on the liquid inlet pipe 31 and used for monitoring the flow of liquid in the liquid inlet pipe 31, so that the liquid capacity entering the mixing pipe 1 is judged, and the accuracy of the mixing ratio of the mixed liquid is effectively guaranteed.

Further, in order to improve the stirring uniformity, a plurality of through holes with different diameters are formed in blades on the spiral stirring piece 4, and the length and the torsion angle of different blades are different, so that the solution is driven to generate direction-changing spiral motion. When the spiral stirring piece 4 rotates, the blades rotate to drive the mixed liquid together, the mixed liquid generates turbulence and turbulent flow in the flowing process, and the violent flow transformation further accelerates the mixing of the liquid, so that the mixing uniformity is effectively improved.
