[0031] A motor 5 is fixed on the side of the fixed plate 6 away from the mixing tank 2. The output end of the motor 5 is connected to the stirring roller 4 through the bearing. The stirring roller 4 is parallel to the support rod 3 and extends vertically into the mixing tank 2 for stirring the fracturing fluid inside the mixing tank 2. A switch 7 is also provided at the top of the fixed plate 6. The switch 7 is used to control the start and stop of the motor 5.

[0032] The support rod 3 also has two threaded grooves 10 that mate with the bolts 9. The threaded grooves 10 are located on the side of the support rod 3 away from the base 1. One threaded groove 10 is located at the top of the support rod 3 and the other is located in the middle of the support rod 3. The distance between the two threaded grooves 10 is greater than the height of the stirring roller 4 inside the mixing tank 2.

[0033] In use, slide the moving block 8 to the threaded groove 10 in the middle of the support rod 3, screw the bolt 9 into the threaded groove 10 to fix the moving block 8 and the fixing plate 6, turn on the switch 7, the motor 5 rotates, driving the stirring roller 4 in the mixing tank 2 to rotate, stirring and mixing the biological enzyme fracturing fluid inside.

When the moving block 8 moves to the threaded groove 10 at the top, screw the bolt 9 into the threaded groove 10 at the top, and the moving block 8 and the fixing plate 6 are fixed. Since the distance between the two threaded grooves 10 is greater than the height of the stirring roller 4 inside the mixing tank 2, the stirring roller 4 can be completely moved out of the mixing tank 2, which makes it convenient to take out the mixing tank 2 for cleaning.

[0034] Example 2

[0035] Based on Example 1, in this example, a baffle 16 is placed on the mixing tank 2 to cover the feed inlet of the mixing tank 2.
