The stirring tank body 1 is filled with a to-be-mixed liquid to be mixed, and when heating or cooling is needed, the stirring tank body 1 is placed in a water bath or an oil bath, or the stirring tank body 1 is heated or cooled by a tank wall jacket. In this embodiment, a stirring tank 1 without a jacket on the tank wall is adopted, the stirring tank 1 is made of glass, and the stirring tank 1 is a cylindrical tank with an inner diameter of 25cm and a height of 30 cm.
Through experiments, the inventor finds that the turbine type or propulsion type stirring blade 23 is beneficial to generating vortex in the liquid-liquid stirring and mixing process, and the turbine type stirring blade 23 is adopted in the embodiment.
The liquid storage tank 4 is used for containing additive liquid mixed with the liquid to be mixed, and a cylindrical tank body with the inner diameter of 8cm and the height of 10cm is adopted in the embodiment. The liquid storage tank 4 is hermetically connected with the stirring shaft 2, so that the additive liquid is prevented from leaking at the 6 position of the tubular shaft connecting part.
The hollow structure design of the stirring shaft 2 and the liquid outlet pipe 5 forms a hollow pipeline 7 for the flow of the additive liquid, and the additive liquid in the liquid storage tank 4 enters the stirring tank body 1 through the hollow pipeline 7.
Through the solid structure design from the tubular shaft connecting part 6 to the bottom of the inner end 21 of the shaft, the additive liquid is prevented from continuously flowing towards the bottom of the inner end 21 of the shaft after passing through the tubular shaft connecting part 6.
A switch 24 or a valve for controlling the liquid flow in the hollow pipeline 7 is arranged on the stirring shaft 2 between the liquid storage tank 4 and the motor 3.
Further, the pipe shaft connecting part 6 comprises a flow dividing part 61 protruding towards the direction of the outer end 22 of the shaft, and the top end of the flow dividing part 61 is not higher than the pipe shaft inner wall connecting point 62 of the liquid outlet pipe 5 and the stirring shaft 2; the minimum pipe diameter of the flow dividing gap 63 formed between the flow dividing part 61 and the inner wall of the liquid outlet pipe 5 is half of the inner diameter of the hollow pipeline 7.
The raised flow dividing part 61 divides the liquid to the liquid outlet pipe 5 when the liquid to be added flows to the pipe shaft connecting part 6. The pipe diameter of a shunting gap 63 formed between the shunting part 61 and the inner wall of the liquid outlet pipe 5 is smaller than the inner diameter of the hollow pipeline 7, so that the flow speed of liquid to be added from the liquid storage tank 4 to the pipe shaft connecting part 6 is reduced. Meanwhile, the top end of the shunting part 61 is not higher than the pipe shaft inner wall connection point 62 of the liquid outlet pipe 5 and the stirring shaft 2, and the minimum pipe diameter of the shunting gap 63 formed between the shunting part 61 and the inner wall of the liquid outlet pipe 5 is not less than one third of the inner diameter of the hollow pipeline 7, so that the phenomenon that liquid to be added is retained due to the fact that the pipe diameter of the shunting gap 63 is too small is effectively avoided.
Furthermore, the tank body of the liquid storage tank 4 is symmetrical by taking the stirring shaft 2 as an axis, and the center of the bottom end of the liquid storage tank 4 is fixedly connected with the stirring shaft 2.
Through fixed connection, when the stirring shaft 2 rotates, the liquid storage tank 4 also rotates along with the stirring shaft 2, and the tank body of the liquid storage tank 4 is of a symmetrical structure with the stirring shaft 2 as an axis, so that the stability of the liquid storage tank 4 in the rotating process is ensured.
Further, the liquid storage tank 4 comprises an inner tank wall positioned on the inner side of the tank body, and six baffle plates 41 protruding towards the central axis 8 of the liquid storage tank 4 are arranged on the inner side of the inner tank wall.
Through the arrangement of at least one baffle 41, the additive liquid in the liquid storage tank 4 is stirred under the action of the baffle 41 during the rotation of the liquid storage tank 4. In order to prevent the stirring intensity of the additive solution from becoming excessive, the inventors have found that it is most appropriate to set the width of the baffle plate 41 to be one third to one fifth of the distance between the inner tank wall and the central axis 8 of the stock tank 4, and in the present embodiment, the width of the baffle plate 41 is set to be one third of the distance between the inner tank wall and the central axis 8 of the stock tank 4.
Furthermore, the liquid outlet pipe 5 forms an included angle B of 60 degrees with the bottom direction of the shaft inner end 21. The inventor utilizes an included angle B formed by the liquid outlet pipe 5 and the bottom direction of the inner end 21 of the shaft, when the stirring shaft 2 rotates, liquid in the liquid outlet pipe 5 is thrown out under the action of centrifugal force and gravity, and through tests, the included angle B is preferably 10-80 degrees.
Further, the liquid outlet pipe 5 comprises a liquid outlet 51, and the distance between the liquid outlet 51 and the bottom of the stirring tank body 1 is 5/6 of the internal height of the stirring tank body 1.
The distance between the liquid outlet 51 and the bottom of the stirring tank body 1 is not less than three-fourths of the internal height of the stirring tank body 1 by controlling the distance between the liquid outlet 51 and the bottom of the stirring tank body 1, so that the liquid outlet 51 is ensured not to be immersed in the liquid to be mixed.
Further, the inner diameter of the hollow pipe 7 is 5 mm. The inventor finds that the liquid can flow out from the liquid outlet pipe 5 too fast even without the action of centrifugal force due to the excessively large inner diameter of the hollow pipeline 7, the liquid can flow out too slowly and even can be blocked due to the excessively small inner diameter of the hollow pipeline 7, and the inner diameter of the hollow pipeline 7 is preferably 3-6 mm through tests.
Furthermore, a guide plate 9 protruding into the stirring tank is arranged on the inner wall of the stirring tank body 1.

The inventor sets up guide plate 9 slant and the height ratio end 92 of head end 91 sets up highly, and when the rotatory stirring of (mixing) shaft 2, be located the agitator tank body 1 edge treat that the liquid that mixes gushes to head end 91 along guide plate 9, and treat that the liquid feeding flies to flow to end 92 direction behind on guide plate 9. In this embodiment, after the inner wall of the stirring tank body 1 is unfolded by the oblique angle, the included angle C between the horizontal direction and the connection line between the head end 91 and the tail end 92 is set to 30 °, so that the liquid to be added is accumulated on the guide plate 9 for a certain time and then is mixed with the liquid to be mixed. In order to enable liquid to be added to be capable of being more in flying jet on the guide plate 9 and mixed with the surging liquid to be mixed, the inventor sets the head end 91 higher than the liquid level of the liquid in the stirring tank body 1, sets the tail end 92 lower than the liquid level of the liquid in the stirring tank body 1, takes the liquid level of the liquid in the stirring tank body 1 in a static state as a liquid level plane, and takes the orthographic projection from the top of the stirring tank body 1 to the bottom of the stirring tank body 1, and the shadow shape of the guide plate 9 on the liquid level plane is closed.
Further, the width of guide plate 9 is the tenth of the 8 distances of 1 inner wall of agitator tank and the 1 central axis of agitator tank, and the contained angle D between guide plate 9 and 1 inner wall below of agitator tank is 60. The width of the guide plate 9 influences the surging of the liquid to be mixed and the retention time of the additive liquid on the guide plate 9,
