The existing raw material dissolving equipment for triethyl phosphate preparation does not have the functions of heating and automatic scraping of the inner wall during use, and the preparation process of triethyl phosphate generally requires certain temperature conditions to promote the dissolution and reaction of raw materials. If the equipment does not have a heating function or the heating effect is not good, it will directly affect the reaction rate, resulting in low production efficiency. In order to make up for the lack of heating function, an external heat source may be used to heat the equipment, which not only increases the operation complexity, but also may increase the energy consumption, which is not conducive to energy saving and emission reduction. In the preparation process of triethyl phosphate, the raw materials and products may form scale on the inner wall of the equipment. If the equipment does not have the function of automatic scraping of the inner wall, the scale will gradually accumulate, affecting the heat transfer efficiency and reaction effect of the equipment. The accumulation of scale also increases the difficulty and cost of cleaning the equipment. In order to remove the scale, manual cleaning may be required, which not only affects the production continuity, but also may damage the equipment. The impurities in the scale may fall off and mix into the product, resulting in a decrease in product quality. In addition, the scale may change the shape of the flow channel of the equipment, affecting the flow and mixing effect of the material, and further affecting the product quality.
