Previous mixing methods are insufficient to effectively replace materials at different locations within the reactor, resulting in uneven mixing of materials at the bottom and top, which affects product quality. Utility Model Content

Several slots are opened on the outer wall of the fixed sleeve. The rotor blades are all located inside the fixed sleeve.

[0008] Furthermore, the stirring mechanism includes a hollow rod rotatably connected to the top of the reactor, the bottom of which extends into the interior of the reactor, and the rotating rod is slidably connected to the inner wall of the hollow rod.

[0009] Furthermore, a second fixing rod is fixedly connected to the top of the reactor, a first bevel gear is fixedly connected to the outer wall of the hollow rod, a second fixing rod is rotatably connected to the outer wall of the second fixing rod, and the first bevel gear meshes with the second bevel gear.

Several slots 27 are opened on the outer wall of the fixed sleeve 26. The rotor blades 24 are all located inside the fixed sleeve 26. Through the shearing and mixing mechanism 2, the rotating rod 23 drives... Multiple rotor blades 24 rotate, enabling them to mix and stir the solid phenolic curing agent synthesis raw materials inside the reactor 1. In conjunction with the fixed sleeve 26 outside the rotor blades 24 and the multiple slots 27 on the fixed sleeve 26, the raw materials are driven through the slots 27 into the fixed sleeve 26.

In addition, the multiple spiral stirring rods 38 can stir and mix the material, further improving the overall stirring effect.
