This invention relates to the field of mixing device technology and discloses a mixing device for producing chemical additives for oilfield fracturing. The device includes a mixing tank and a main drive shaft. The mixing tank is internally equipped with a mounting frame, a wall scraper, and a shearing blade. The mounting frame is located inside the mixing tank, and the wall scraper is fixedly mounted on the mounting frame. Two shearing blades are symmetrically arranged on both sides of the mounting frame. This mixing device for producing chemical additives for oilfield fracturing, through the linkage of the main drive shaft, internal gear disc, slider, and spacing adjustment mechanism, allows the main shaft to rotate forward, first driving the two shearing blades to approach to their minimum spacing before rotating as a whole.

This achieves adaptive adjustment of shear strength according to the process stage, solving the problem that traditional mixing methods, due to their single strength, cannot simultaneously meet the requirements of dispersion and maturation.
