A low temperature concentration tank

Abstract

This utility model discloses a low-temperature concentration tank, including a tank body. A spiral tube is fixedly installed on the outside of the tank body, and the spiral tube is connected to a circulating heating structure through a connecting pipe. A through hole is opened at the top of the tank body, and a fixed cover is installed above the through hole. A drive motor is installed on the outside of the fixed cover, and the drive motor can drive the spiral conveying rod and stirring rod mechanism installed inside the fixed cover to rotate. A hollow conveying cylinder is installed inside the tank body to cooperate with the spiral conveying rod. The hollow conveying cylinder is connected to the spiral tube and the circulating heating structure through a conveying pipe. This utility model achieves uniform heating of the liquid inside the tank body by setting a spiral tube on the outside of the tank body, setting a hollow conveying cylinder inside the tank body, and using a circulating heating structure to circulate and heat the gas inside the spiral tube and the hollow conveying cylinder. The hollow conveying cylinder heats the liquid at the center position, and the spiral tube heats the liquid at the outer edge.
