Abstract

This utility model discloses a liquid alkali addition control mechanism, relating to the field of glycerol distillation equipment technology. It includes: a distillation tank and a tank cover installed on top of the tank. A mixing mechanism for agitating glycerol is provided below the tank cover to neutralize acids in the glycerol with liquid alkali. A liquid alkali storage component, a liquid alkali addition mechanism, and a pH meter are installed on the upper surface of the tank cover. The liquid alkali addition mechanism and the liquid alkali storage component are connected. Through the cooperation between the liquid alkali addition mechanism, the liquid alkali storage component, the pH meter, and the controller, an electric push rod drives a piston upwards, allowing liquid alkali to enter the suction cylinder through the inlet pipe. Under the action of the piston pushed by the electric push rod, the liquid alkali is quantitatively added through the outlet pipe. Simultaneously, combined with real-time monitoring by the pH meter, automated and precise control of liquid alkali addition is achieved, effectively improving the neutralization efficiency and quality of acids in the glycerol.
