[0027] The utility model will be further explained in detail in connection with the drawings and embodiments, these drawings are all simplified schematic diagram, only with the schematic way shows the basic structure of the utility model, therefore it only shows the related structure of the utility model.

[0028] As Figure 1 The porous spherical resin preparation catalyst injection mixing equipment, including: the reaction kettle 1, the protection assembly 5 that sets up at the bottom of reaction kettle 1, the flow guide assembly 6 that sets up at the inner wall of the bottom of reaction kettle 1 and the wall scraping assembly 7 that sets up at the circumferential inner wall of reaction kettle 1,

[0029] As Figures 2-3 The flow guide assembly 6 includes: the connecting pipe 601, the threaded blade 603 that sets up at the circumferential outer wall of connecting pipe 601, a plurality of fixed blocks 605 that sets up at the inner wall of the bottom of reaction kettle 1 and the same flow guide cylinder 604 that sets up at the top of a plurality of fixed blocks 605,

[0030] The connecting pipe 601 is rotatably connected to the inner wall of the bottom of reaction kettle 1, a plurality of through liquid injection holes 602 are formed in the circumferential inner wall of the bottom of connecting pipe 601, the threaded blade 603 is fixedly connected to the circumferential outer wall of connecting pipe 601, a plurality of fixed blocks 605 are fixedly connected to the inner wall of the bottom of reaction kettle 1, the flow guide cylinder 604 is fixedly connected to the top of a plurality of fixed blocks 605, the circumferential outer wall of threaded blade 603 is tightly attached to the circumferential inner wall of flow guide cylinder 604, and a through groove is arranged between adjacent two fixed blocks 605.

[0031] It should be noted that the flow guide assembly 6 drives the connecting pipe 601 to rotate on the inner wall of the bottom of reaction kettle 1 by the motor 503, so as to realize efficient liquid mixing and flow guide. The plurality of through liquid injection holes 602 formed in the circumferential inner wall of the bottom of connecting pipe 601 can make the liquid materials such as catalyst flow out uniformly from these holes and enter the inside of reaction kettle 1 for mixing, so as to ensure the uniform distribution of materials and improve the mixing efficiency; when the connecting pipe 601 rotates, the threaded blade 603 rotates, and by the friction and extrusion between the threaded shape of the threaded blade 603 and the inner wall of the flow guide cylinder 604, the liquid at the bottom of reaction kettle 1 is pushed upwards and discharged through the flow guide cylinder 604 above and flows back to the inside of reaction kettle 1, and this circulating flow mode can further enhance the mixing effect.

[0032] As Figures 2-3 The protection assembly 5 includes: the motor 503, the protection shell 501 arranged at the bottom of reaction kettle 1, and a plurality of heat dissipation holes 502 arranged on the circumferential outer wall of the protection shell 501;

[0033] The motor 503 is fixedly connected to the bottom of the reactor 1. One end of the output shaft of the motor 503 passes through the reactor 1 and is fixedly connected to the top of the connecting pipe 601. The protective shell 501 is fixedly connected to the bottom of the reactor 1. The motor 503 is located inside the protective shell 501. Several heat dissipation holes 502 are opened through the inner circumference of the protective shell 501.

[0034] It should be noted that the motor 503 can effectively drive the connecting pipe 601 and the flow guiding component 6, ensuring that the driving force of the motor 503 can be fully transmitted to the connecting pipe 601. The protective shell 501 can effectively prevent external debris from interfering with and damaging the motor 503.

Simultaneously, the connecting ring 703 and its stirring rod 704 rotate together with the scraper 702, further enhancing the stirring effect and allowing the materials in the reactor 1 to mix more thoroughly. The injection pipe 4 allows liquids such as catalysts to be directly injected into the connecting pipe 601, and then flows evenly into the reactor 1 through the injection hole 602 at the bottom of the connecting pipe 601. The outlet pipe 3 allows the mixed liquid to be easily discharged from the reactor 1, and the outflow speed and volume can be flexibly adjusted through valve control. Several support rods 2 fixedly connected to the bottom of the reactor 1 provide stable support for the entire equipment.

[0039] In use, this invention involves injecting liquid materials such as catalysts into the connecting pipe 601 through the injection pipe 4. Then, the motor 503 is started, and its output shaft drives the connecting pipe 601 to rotate on the inner wall of the bottom of the reactor 1. The injection hole 602 at the bottom of the connecting pipe 601 evenly distributes the liquid materials such as catalysts into the reactor 1. Simultaneously, the threaded blade 603 rotates with the connecting pipe 601, and through friction and compression against the inner wall of the guide tube 604, pushes the liquid at the bottom of the reactor 1 upwards, forming a circulating flow and enhancing the mixing effect. The rotation of the connecting pipe 601 also drives the synchronous rotation of the wall scraper assembly 7. The scraper 702 closely adheres to the circumferential inner wall of the reactor 1, effectively scraping away residues adhering to the wall. The connecting ring 703 and its stirring rod 704 rotate together with the scraper 702, further enhancing the stirring effect and ensuring more thorough mixing of the materials within the reactor 1. During the operation of motor 503, the protective shell 501 can effectively prevent external debris from interfering with and damaging motor 503, and several heat dissipation holes 502 can ensure that the heat generated by motor 503 can be dissipated in a timely manner.
