Abstract

The invention relates to the technical field of colloidal chemistry related equipment, in particular to a reaction kettle feeding auxiliary device which comprises two material containing areas arranged on a mounting seat, two material containing areas respectively used for containing solid raw materials and liquid raw materials; the liquid material piece is arranged on the frame body and used for conveying liquid raw materials; the solid material piece is arranged on the frame body and used for conveying solid raw materials; a double-channel independent material conveying structure is adopted, and different material conveying means are implemented according to different physical characteristics of liquid raw materials and solid raw materials, specifically, the liquid raw materials are conveyed through the constant-pressure pumping technology, and the solid raw materials are conveyed through the negative-pressure pneumatic conveying principle. The problems of unstable conveying, material blockage, pulsation, cutoff and the like of a conventional conveying mode are effectively solved, raw materials can be stably conveyed, the constant flow speed is ensured, the mixing uniformity of the raw materials in the reaction kettle is ensured, and thus the finished product quality of styrene-butadiene latex is improved.
