[0039] A forward and reverse stirring module is also arranged in the stirring tank 2, and the forward and reverse stirring module includes a stirring motor 9, a first stirring shaft 10 and a second stirring shaft 11. A mounting frame 16 is also arranged on the top of the stirring tank 2. The mounting frame 16 is L-shaped, and its vertical section is connected to the top of the stirring tank 2. A thrust ball bearing 14 is arranged on its horizontal section. At the same time, a thrust ball bearing 14 is also arranged on the top of the stirring tank 2. The two thrust ball bearings 14 are arranged coaxially;

[0040] The stirring motor 9 is arranged at the top of the stirring tank 2, the first stirring shaft 10 is a hollow tubular structure, the middle hollow area of ​​which is a rotating chamber 20, and a baffle is also arranged on the first stirring shaft 10, the lower end of the first stirring shaft 10 passes through the thrust ball bearing 14 arranged at the top of the stirring tank 2 and is inserted into the stirring tank 2, and at the same time, the limit plate 15 located on the first stirring shaft 10 abuts against the thrust ball bearing 14;

[0042] A limit plate 15 is disposed at the top end of the second stirring shaft 11, and the limit plate 15 abuts against a thrust ball bearing 14 disposed on the mounting frame 16;

[0043] At the same time, a driven bevel gear 13 is provided on both the first stirring shaft 10 and the second stirring shaft 11, wherein the driven bevel gear 13 on the second stirring shaft 11 is on the upper side, and a driving bevel gear 12 is also provided on the output shaft of the stirring motor 9, and the driving bevel gear 12 is inserted between the two driven bevel gears 13, and its upper and lower sides are respectively meshed with the two driven bevel gears 13;

[0046] In the above structure, the first stirring rod 18 and the second stirring rod 19 are alternately arranged.

[0050] When in use, different temporary storage tanks are used to store different raw materials. When the drag reducer needs to be prepared, the amount of different raw materials is input into the controller, and the controller controls the opening of each solenoid valve, and at the same time, the amount of raw materials transported by each infusion tube is measured by the flow meter, so as to achieve accurate control of the amount of raw materials. After the various raw materials enter the mixing tank, the forward and reverse stirring modules located in the mixing tank will generate forward rotation and reverse rotation at the same time, and then stir the raw materials through two different rotational motions to achieve the production of drag reducer.
