[0035] The kettle body 1 is made of stainless steel with high corrosion resistance and is cylindrical in shape. A discharge port 12 is provided at the bottom of the kettle body 1 to facilitate the discharge of the mixed product. A valve is installed at the discharge port 12 to control the opening and closing of the discharge port 12.

[0036] Reference Figure 2The stirring mechanism 3 includes a first driving member 31 and a stirring rod 32. The first driving member 31 is mounted on the kettle body 1, and the stirring rod 32 is rotatably connected in the kettle body 1 and fixedly connected to the output end of the first driving member 31. In this embodiment, the first driving member 31 is a motor, so that the first driving member 31 is used to drive the stirring rod 32 to rotate.

[0037] A stirring blade 33 is installed on the stirring rod 32, so that when the first driving member 31 drives the stirring rod 32 to rotate, the stirring rod 32 can drive the stirring blade 33 to rotate, so that the stirring blade 33 can be used to stir the raw materials in the reactor, thereby achieving mixing of different raw materials.

[0038] The crushing mechanism 2 includes a receiving platform 21, a driving assembly 22 and a crushing assembly 23. The receiving platform 21 is mounted on the stirring rod 32 and is arranged close to the feed port 11. The end of the receiving platform 21 close to the feed port 11 is hemispherical in shape, and the surface is coated with a polytetrafluoroethylene anti-stick coating to reduce the adhesion of the raw materials, so that the raw materials entering the reactor can slide off the receiving platform 21 more smoothly.

[0039] Reference Figure 2 A guide ring 13 is fixedly connected inside the kettle body 1, and the guide ring 13 is arranged close to the material receiving platform 21, and a conical groove 14 is formed between the guide ring 13 and the circumferential outer wall of the material receiving platform 21, and the larger end of the conical groove 14 is arranged close to the feed port 11, so that after the raw material slides off the material receiving platform 21, the raw material can fall smoothly along the conical groove 14.

[0040] Reference Figure 2 and Figure 3 The receiving platform 21 is provided with a receiving cavity 211, and the stirring rod 32 is provided through the receiving cavity 211. The receiving platform 21 is provided with a plurality of recesses 212, and the plurality of recesses 212 are evenly distributed on the receiving platform 21 and are respectively connected with the receiving cavity 211.

[0041] Reference Figure 2 The driving assembly 22 includes a second driving member 221, a sliding sleeve 222 and a connecting rod 223. The second driving member 221 and the sliding sleeve 222 are respectively arranged in the accommodating cavity 211, and the sliding sleeve 222 is sleeved on the stirring rod 32, and the second driving member 221 is located below the sliding sleeve 222.

[0042] The second driving member 221 includes a box body 2211, a spring 2212 and an electromagnet 2213. The box body 2211 is installed in the accommodating cavity 211 and is located below the sliding sleeve 222. The electromagnet 2213 is installed in the box body 2211, so that the box body 2211 can be used to protect the electromagnet 2213. In other embodiments, the second driving member 221 can also be directly set as a cylinder or an electric push rod.

[0043] The spring 2212 is disposed between the box body 2211 and the sliding sleeve 222. When the electromagnet 2213 is energized, the electromagnet 2213 can apply suction to the sliding sleeve 222, so that the sliding sleeve 222 moves toward the box body 2211. At this time, the spring 2212 is compressed. When the electromagnet 2213 is de-energized, the spring 2212 can push the sliding sleeve 222 to move away from the box body 2211, so that the electromagnet 2213 and the spring 2212 cooperate with each other to drive the sliding sleeve 222 to reciprocate.

[0044] When the spring 2212 drives the sliding sleeve 222 to move, the sliding sleeve 222 can hit the inner wall of the accommodating chamber 211 to cause the material receiving platform 21 to vibrate, thereby facilitating the raw materials to fall from the surface of the material receiving platform 21, thereby reducing the possibility of raw materials accumulating on the surface of the material receiving platform 21 and causing blockage.

[0045] Reference Figure 2 and Figure 3 The crushing assembly 23 includes a first cutter 231 and a second cutter 232. The first cutter 231 is fixedly connected to the circumferential inner wall of the guide ring 13 and is located in the conical groove 14. The material of the first cutter 231 is cemented carbide, which has high hardness and wear resistance. A plurality of first cutters 231 are provided, and the plurality of first cutters 231 are evenly distributed around the axis of the guide ring 13.

[0046] The number of the second cutters 232 and the number of the connecting rods 223 are equal to the number of the openings of the clearance grooves 212, and one second cutter 232 is slidably inserted in one clearance groove 212. One end of the second cutter 232 extends into the conical groove 14, and the other end of the second cutter 232 extends into the accommodating cavity 211 and is hinged to the connecting rod 223. The end of the connecting rod 223 away from the second cutter 232 is hinged to the sliding sleeve 222.

[0047] When the sliding sleeve 222 reciprocates, the sliding sleeve 222 can drive the second cutter 232 to slide reciprocatingly in the clearance groove 212 through the connecting rod 223, so that the second cutter 232 approaches or moves away from the first cutter 231, so as to impact the agglomerated raw materials and effectively break the agglomerated raw materials.

[0049] The stopper 213 can limit the moving path of the second cutter 232 in the accommodating chamber 211 to ensure that the second cutter 232 can stably move in a predetermined direction. This not only improves the movement accuracy of the second cutter 232, but also prevents the second cutter 232 from deflecting or getting stuck during operation, thereby ensuring the reliability and stability of the crushing mechanism 2 and further improving the overall performance of the mixing reactor.

[0050] The implementation principle of a multifunctional mixing reactor in the embodiment of the present application is as follows: when different powdered raw materials need to be mixed, the powdered raw materials are first transported from the feed port 11 into the reactor body 1, and the raw materials fall onto the receiving platform 21 and fall downward. In this process, the electromagnet 2213 repeats the power-on and power-off operations, and with the cooperation of the spring 2212, drives the sliding sleeve 222 to reciprocate, and the sliding sleeve 222 drives the second cutter 232 to reciprocate through the connecting rod 223, so that the second cutter 232 impacts the raw materials. At the same time, the first driving member 31 drives the receiving platform 21 to rotate through the stirring rod 32, and the receiving platform 21 drives the second cutter 232 to rotate, and the second cutter 232 hits the raw materials to further break the agglomerated raw materials, and the raw materials are quickly and evenly dispersed after breaking. The crushed and dispersed raw materials will continue to fall, and the stirring rod 32 will drive the stirring blade 33 to stir the raw materials, thereby achieving stirring and mixing of the raw materials.

In this embodiment, the limiting groove 2323 is a T-shaped groove, and the smaller end of the limiting groove 2323 passes through the end surface of the handle 2321.

[0053] One end of the blade body 2322 is slidably inserted into the limiting groove 2323 , and the other end of the blade body 2322 is arranged to pass through the giving way groove 212 , so that the connecting rod 223 can drive the blade body 2322 to move through the blade handle 2321 .

[0054] The adjustment component 24 includes a third driving member 241 and an adjustment block 242. The third driving member 241 is mounted on the knife handle 2321, the adjustment block 242 is mounted on the knife body 2322 and is slidably inserted in the limit groove 2323, and the adjustment block 242 is connected to the third driving member 241. In this embodiment, the third driving member 241 is a cylinder, so that the third driving member 241 can be used to drive the adjustment block 242 to move, and the adjustment block 242 can drive the knife body 2322 to move, thereby facilitating the adjustment of the spacing between the knife handle 2321 and the knife body 2322. This design allows the second cutter 232 to flexibly adjust its length according to actual working conditions, so as to better adapt to agglomerated raw materials of different sizes, thereby helping to improve the crushing efficiency of the raw materials.

[0055] In other embodiments, the third driving member 241 may also be designed as a motor screw structure to improve the connection stability between the knife body 2322 and the knife handle 2321 .
