The driving block 9 can be controlled to drive the jet pipe 8 to move inside the tank body 1 through the threaded cooperation relationship between the driving rod 10 and the driving block 9.

[0046] In summary, when the overall equipment is in use:

[0047] The first motor 3 is started, and the rotation of the stirring shaft 2 is controlled by the first motor 3. The rotation of the stirring shaft 2 can control the rotation of the first spiral blade 4 and the second spiral blade 5. Since the thread directions of the first spiral blade 4 and the second spiral blade 5 are arranged in opposite directions, the mixed liquid inside the tank body 1 can be fully stirred during the rotation process, thereby avoiding the precipitation of the mixed liquid;

[0048] Synchronously, during the rotation of the stirring shaft 2, the stirring column 6 will be driven to rotate synchronously, thereby enhancing the mixing effect and efficiency of the mixed liquid. At the same time, when the stirring column 6 rotates, it can drive the spiral spoiler blade 7 to rotate along the axis of the stirring shaft 2. The spiral spoiler blade 7 will also rotate along the axis of the stirring column 6 under the action of the liquid flow force, thereby disturbing the flow direction of the liquid generated by the first spiral blade 4 and the second spiral blade 5, thereby further enhancing the inversion mixing effect of the mixed liquid inside the tank body 1, and further improving the anti-sedimentation effect of the mixed liquid inside the tank body 1;

[0049] During this process, the high-pressure air flow can be delivered to the inside of the jet pipe 8 through the air delivery hose 14 by the high-pressure air pump 13, and blown out through the high-pressure jet head 15;

[0050] At the same time, the second motor 11 is started. The second motor 11 and the synchronous belt structure 12 can be used to control the synchronous rotation of the two sets of driving rods 10. The driving block 9 can be controlled to drive the jet pipe 8 to move inside the tank body 1 through the threaded matching relationship between the driving rod 10 and the driving block 9. By controlling the bidirectional rotation of the second motor 11, the jet pipe 8 can be reciprocated inside the tank body 1, thereby blowing the bottom of the tank body 1 to prevent the presence of precipitated substances in the mixed liquid;

[0051] Moreover, by adopting this mobile blowing method, compared with the fixed installation of the transmission jet pipe 8, the existence of dead angles can be reduced and the anti-sedimentation effect at the bottom end of the tank body 1 can be improved.
