AI Technical Summary

Technical Problem

In the existing cooling devices for the rotor and mixing chamber of the internal mixer, the cooling water channels are U-shaped flow channels with smooth inner walls, resulting in laminar water film adhering to the wall and low-speed dead water zones. This leads to low heat transfer efficiency, increased heat exchange resistance, and easy scaling, making it difficult to meet the heat dissipation requirements of high-load mixing conditions.

Method used

A forced circulation cooling device is adopted, including a bubble assembly and a zoned temperature control design. The bubble assembly generates fine bubbles to stir the water film, breaking the laminar water film attached to the wall and improving heat transfer efficiency. The zoned temperature control of the cooling water is achieved through cooling tank one and cooling tank two to prevent the temperature from rising.

Benefits of technology

It effectively reduces the occurrence of laminar flow water film and low-speed dead water zone, significantly reduces heat exchange resistance, reduces scaling in water channels, improves heat dissipation capacity under high-load mixing conditions, and ensures the stability and uniformity of cooling water.
