[0024] The feed premixing mechanism 20 can premix the re-fed materials and then add them into the reactor main body 10 for mixing, thereby further improving the mixing efficiency of the materials.

[0025] See also Figure 1 , Figure 3 and Figure 4The main body 10 of the reactor includes a kettle 110 and a stirring assembly 120. The stirring assembly 120 is installed inside the kettle 110, and a feeding port and a discharging port are respectively provided at the top and bottom of the kettle 110. The feed premixing mechanism 20 includes a loading barrel 210, a premixing assembly 220 and a discharge pipe 230. The top end of the discharge pipe 230 is connected to the bottom end of the loading barrel 210, and the bottom end of the discharge pipe 230 is connected to the top of the kettle 110. A discharge valve is provided on the discharge pipe 230. The premixing assembly 220 includes a bracket 221, a driving motor 222, a stirring rod 223, a barrel 224, a spiral blade 225, a stirring blade 226 and a mesh plate 227. The bracket 221 is arranged above the loading barrel 210, and the bracket 221 and the loading barrel 210 are fixed by bolts; the driving motor 222 is installed above the bracket 221. The top of the stirring rod 223 is connected to the output shaft end of the driving motor 222 through a coupling, the spiral blade 225 is fixedly arranged on the outside of the stirring rod 223, and the barrel 224 is fixedly sleeved on the outside of the spiral blade 225. The stirring blade 226 is fixed on the outside of the barrel 224, and the stirring blade 226 and the barrel 224 are fixed by bolts; and the mesh plate 227 is arranged on the inside of the stirring blade 226.

[0026] The stirring assembly 120 inside the kettle 110 stirs and mixes the additives inside the kettle 110. When it is necessary to add multiple materials to the kettle 110 for mixing, the multiple materials can be added to the upper barrel 210 in advance, and the driving motor 222 in the premixing assembly 220 drives the stirring rod 223 to rotate. The rotating stirring rod 223 will simultaneously drive the spiral blade 225 as well as the stirring blade 226 and the mesh plate 227 to rotate. The rotating stirring blade 226 and the mesh plate 227 can premix the materials inside the upper barrel 210, and the arrangement of the mesh plate 227 increases the mixing contact area between the materials when rotating, thereby improving the material premixing effect. The rotating spiral blade 225 transports the material at the bottom of the barrel 224 to the top of the barrel 224, that is, transports the material on the bottom side of the upper barrel 210 upward, further improving the material premixing effect. The premixed materials are finally discharged from the discharge pipe 230 into the interior of the kettle 110 and then mixed by the stirring assembly 120, thereby saving material mixing time and improving the mixing efficiency of the materials.

[0027] For specific settings, see Figure 1 The reactor body 10 further includes a jacket 140, which is fixedly mounted on the outside of the reactor 110. The jacket 140 can be provided with inlets and outlets for adding a heat-conducting solvent to quickly increase the temperature inside the reactor 110.

[0028] In the above specific implementation, please refer to Figure 2The stirring assembly 120 includes a reduction motor 121, a stirring shaft 122 and a stirrer 123. The reduction motor 121 is installed above the kettle 110, the stirring shaft 122 is located inside the kettle 110, and the top end of the stirring shaft 122 rotates through the kettle 110 and is connected to the output shaft end of the reduction motor 121, and the stirrer 123 is installed on the stirring shaft 122. The reduction motor 121 drives the stirring shaft 122 to rotate, and the rotating stirring shaft 122 drives the stirrer 123 to rotate and mix the liquid inside the kettle 110.

[0029] For further information, see Figure 3 The feed premixing mechanism 20 further includes a fixing frame 240, which is sleeved on the outside of the loading barrel 210, and the bottom end of the fixing frame 240 is fixedly connected to the top wall of the kettle 110. The fixing frame 240 is used to further stably support the loading barrel 210.

[0030] It should be noted that the specific model specifications of the reduction motor 121 and the drive motor 222 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail. The power supply and principle of the reduction motor 121 and the drive motor 222 are clear to those skilled in the art and will not be described in detail here.

[0031] The working principle of the reactor: When in use, the stirring assembly 120 inside the kettle 110 stirs and mixes the additives inside the kettle 110. When it is necessary to add multiple materials to the kettle 110 for mixing, the multiple materials can be added to the upper barrel 210 in advance, and the driving motor 222 in the premixing assembly 220 drives the stirring rod 223 to rotate. The rotating stirring rod 223 will simultaneously drive the spiral blade 225, the stirring blade 226 and the mesh plate 227 to rotate. The rotating stirring blade 226 and the mesh plate 227 can premix the materials inside the upper barrel 210, and the setting of the mesh plate 227 increases the mixing contact area between the materials when rotating, thereby improving the material premixing effect. The rotating spiral blade 225 transports the material at the bottom of the barrel 224 to the top of the barrel 224, that is, the material on the bottom side of the upper barrel 210 is transported upward, further improving the material premixing effect. The premixed materials are finally discharged from the discharge pipe 230 into the interior of the kettle 110 and then mixed by the stirring assembly 120, thereby saving material mixing time and improving the mixing efficiency of the materials.

[0032] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
