8. A method of using an internal material cooling pipe in a cooling tank according to any one of claims 1-7, characterized in that: Includes the following steps: Step 1, Integrated fluid supply guidance: The coolant in the external liquid supply device is introduced into the rotary support assembly (40) through the coaxial nested pipe assembly on the sealing cover (11). The coaxial nested pipe assembly consists of a coolant inlet pipe (30) and a coolant outlet pipe (20) built into its inner cavity. The outer wall of the coolant inlet pipe (30) is connected to the external liquid supply pipeline through the rotary sealed conveying sleeve (32). The coolant enters the cavity of the coolant inlet pipe (30) through multiple sets of conveying through holes (33) evenly distributed on the coolant inlet pipe (30). Step 2: Enhanced heat transfer through rotational disturbance: Start the servo motor and drive the two coaxially arranged cooling coils (50) to rotate synchronously in the tank (10) through the rotating support assembly (40). At the same time, the coolant in step 1 is distributed by the rotating support assembly (40) to one of the cooling coils (50). The rotation of the cooling coils (50) creates mechanical disturbance to the material in the tank, so that the material can fully contact the outer wall of the two cooling coils (50) to complete the heat exchange. Step 3, Isolation Loop Export: After heat exchange, the coolant flows into another set of cooling coils (50) through the annular connecting pipe (52) at the bottom of the two sets of cooling coils (50), and then is introduced into the coolant discharge pipe (20) of the coaxial nested pipe assembly through the double cavity isolation structure in the rotating support assembly (40). Finally, it is discharged from the coolant discharge pipe (20) to the recovery end of the external liquid supply equipment, forming a closed loop of "liquid supply-heat exchange-recovery".

The motor shaft of the servo motor is connected to the transmission plate (60) on the outer wall of the coolant discharge pipe (20) of the coaxial nested pipe assembly through the transmission belt, which drives the coolant discharge pipe (20), the rotating support assembly (40) and the two sets of cooling coils (50) to rotate synchronously around the same axis. The annular rotating shell (43) of the rotating support assembly (40) cooperates with the annular guide groove (111) on the sealing cover (11) through the guide ring (41) to constrain the rotation trajectory to avoid eccentric vibration and realize the integrated operation of "drive-support-guide".

The coolant in step 1 flows into the first cavity through multiple sets of conveying connection pipes (34) between the coolant inlet pipe (30) and the annular rotating housing (43), and is only distributed to a set of cooling coils (50) connected to the first cavity. In step 3, the coolant flows into the second cavity of the annular rotating shell (43) through another set of cooling coils (50), and then is introduced into the coolant discharge pipe (20) through multiple sets of output connection pipes (21) between the coolant discharge pipe (20) and the annular rotating shell (43). The coolant is physically isolated by the dual cavities to achieve "no mixing of the inlet and outlet paths".
