[0017] The batching mechanism for producing polycarboxylic acid water-reducing agent is provided with a heating structure. First, hot water is introduced into the water inlet pipe so that the hot water completely submerges the heating tube inside the heating box. At this time, the hot water inside the heating box will heat the material moving inside the heating tube. After the heating is completed, the hot water will be discharged from the heating box through the water outlet pipe to complete the circulation of the hot water inside the heating box. By heating the material inside the heating tube, the mixing rate of the material and the solvent is increased.

[0018] Furthermore, a mixing structure is provided, and two different materials are added into the premixing tank through two feeding ports, and at this time, the stirring motor is started to drive the premixing stirring rod to rotate inside the premixing tank, so that the two different materials are preliminarily mixed inside the premixing tank, so that when the materials are subjected to subsequent steps, the two materials are mixed more fully;

[0021] Furthermore, a control module is provided, and the height data of the float on the outside of the sensing rod will be transmitted to the inside of the control module through a wire. The control module calculates the amount of solvent inside the main mixing tank according to the height data of the float through a single-chip microcomputer.

When the amount of material reaches the concentration mixed with the solvent inside the main mixing tank, the control module will control the control valve to cut off the pipeline to prevent excessive or insufficient feeding, which would result in substandard concentration.
