The raw liquid is sprayed into the stirring cylinder 1 through the rotating spray head 10, thereby increasing the mixing degree of the liquid.

[0040] When stirring, first, the raw materials are sprayed into the stirring cylinder 1 by the rotating spray head 10, wherein the amount of raw materials sprayed per unit time by the rotating spray head 10 can be controlled by adjusting the rotating speed of the motor A12, so that the raw materials can be more evenly distributed before being fully mixed, thereby improving the subsequent mixing effect, then the rotating member 4 is driven to rotate by the motor A12, and the gear ring A6 is driven to rotate, since the motor A12 drives the rotating member 4 to rotate, the gear ring A6 is connected with the turbulence plate 11, thereby driving the turbulence plate 11 to rotate in the stirring cylinder 1, so that the raw material liquid in the stirring cylinder 1 is fully mixed and stirred, thereby improving the mixing efficiency and effect.

[0041] The current existing liquid reaction kettle is often stirred by stirring blades, but the single stirring blade will make the liquid spin or form vortex while stirring the liquid, thereby affecting the stirring and mixing effect, the stirring efficiency is low and the stirring time is long; the present scheme designs a reaction kettle for preparing a foaming agent for fracturing, the rotating member 4 is driven to rotate by the motor A12, the turbulence plate 11 is driven to rotate by the motor B13 and the gear mechanism, the rotating speeds of the two are different, the mixing degree of the liquid is increased, the single stirring track is avoided, and the vortex is avoided to further mix the liquid uniformly; meanwhile, the rotatable spray head 10 is arranged, so that the raw materials enter the stirring cylinder 1 by rotating and spraying into the cylinder, and the mixing degree of the liquid is increased.

[0044] It should be noted that the two turbulence plates 11 on the two connecting rods move at high speed in mutually perpendicular planes, so that the raw materials are more fully disturbed from multiple angles, thereby achieving a more ideal mixing effect; here only one combination mode that can achieve this effect is listed, and more turbulence plate 11 groups can be set according to needs in practice, as long as the movement direction of each turbulence plate 11 complies with the aforementioned high-speed movement in mutually perpendicular planes.
