Crystallization circulating cooling system with rapid temperature adjusting function

The utility model discloses a crystallization circulating cooling system with a quick temperature adjusting function, which comprises a crystallization kettle, a water cooling tower and a circulating pump, a cooling water jacket is mounted on the outer side of the crystallization kettle, a cooling water coil pipe is mounted in the crystallization kettle, and the circulating pump is connected with the cooling water jacket. A first cooling water inlet of the cooling water jacket and a second cooling water inlet of the cooling water coil pipe are communicated with a water outlet of the circulating pump, and a first cooling water outlet of the cooling water jacket and a second cooling water outlet of the cooling water coil pipe are both communicated with the water cooling tower. The cooling device is ingenious in structure and convenient to use, a circulating water buffer tank is omitted, cooling water directly enters an inlet of the circulating pump from the water cooling tower, and the cooling water returns to
