[0021] like Figure 1 As shown in the preferred embodiment of the present invention, a modular reaction vessel stirring device includes: a stirring vessel 1 and a stirring structure 2;
[0022] like Figure 2 As shown, the mixing vessel 1 includes a main body 101, an upper cover 102, and support legs 103; the upper cover 102 is connected to the top of the main body 101 by bolts, and the support legs 103 are arranged around the bottom of the main body 101; the main body 101 includes a discharge port 1011 and a discharge valve port 1012, the discharge port 1011 is located at the bottom end of the main body 101, and the discharge valve port 1012 is located inside the discharge port 1011; the upper cover 102 includes an inlet 1021 penetrating the upper cover 102, and a movable cover plate 1022 covering the inlet 1021;
[0023] like Figure 4 As shown, the stirring structure 2 includes a motor 201, a drive shaft 202, a propeller blade 203, a turbine blade 204, and an anchor blade 205. The motor 201 is located on the top of the upper cover 102. One end of the drive shaft 202 passes through the upper cover 102 and is connected to the drive shaft of the motor 201. The other end of the drive shaft 202 is connected to the propeller blade 203. The turbine blade 204 is connected below the propeller blade 203, and the anchor blade 205 is connected below the turbine blade 204.
[0024] Motor 201 drives transmission shaft 202 to rotate, which in turn drives propeller blade 203, turbine blade 204, and anchor blade 205 to rotate and stir in sequence. Propeller blade 203 is located at the top of transmission shaft 202 and generates downward thrust to push the material up and down to circulate, eliminating stratification, which is especially suitable for low viscosity liquids. The special shape and structure of turbine blade 204 can make the material form a strong vortex in reactor 1, which can fully mix the material in different positions and break the stratification between materials. It can effectively improve the mixing uniformity, especially for materials with high viscosity or large density differences. Anchor blade 205 rotates close to the bottom of the reactor, effectively breaking the stratification between the bottom material and the upper material, fully turning the bottom material up and mixing it with the upper material, thus improving the uniformity of the material in the entire reactor.
[0025] As a preferred embodiment of this utility model, it may also have the following additional technical features:
[0026] like Figure 2 As shown, in a preferred embodiment, the stirred tank 1 includes a heating layer 104 and a plurality of temperature detection units 105.

By driving the pressure block 10222 with the first hydraulic cylinder 10221, the cover plate 10223 is raised and lowered, achieving automatic opening and closing of the feed inlet, reducing manual operation, and preventing raw material exposure and environmental pollution.
[0028] like Figure 4 As shown, in a preferred embodiment, the stirring structure 2 has two turbine blades 204, and the two turbine blades 204 have opposite propulsion directions. The arrangement of two opposing turbine blades 204 enhances radial mixing, generates convective shear force, and accelerates dispersion.
