Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a novel stirring device and system for a salt water pool. Background Art

[0002] When producing block ice in ice-making factories at places like fishing ports, the refrigerant and brine in the brine pool need to be stirred. As the brine in the brine pool absorbs heat from the evaporation of the refrigerant flowing through the refrigeration coil, its temperature continues to drop. To improve the cooling effect and shorten the cooling time, the temperature field in the brine pool needs to be kept uniform.

[0003] Usually, multiple vertical agitators are installed in the brine pool to stir the brine in the brine pool to keep the temperature field in the brine pool uniform, thereby improving the refrigeration effect, saving production energy consumption, and improving production efficiency.

[0004] The main shaft rotating support component of the traditional vertical agitator adopts a metal sleeve. Since the impeller of the vertical agitator is constantly subjected to the resistance of water when working, the main shaft of the vertical agitator is vibrated, resulting in uneven force, causing friction between the sleeve and the main shaft and wear.
