[0002] The framework of a hierarchical molecular sieve is primarily composed of silicon and aluminum elements connected by oxygen atoms to form a tetrahedron structure. These tetrahedrons then share vertices and interconnect, ultimately forming the molecular sieve's skeleton structure. Its pore structure includes micropores, mesopores, and macropores, which interpenetrate each other to form a complex, multi-level pore system.

[0003] In the preparation of hierarchical molecular sieves, mixing uniformity is crucial to the performance of the final product. Currently, traditional mixing equipment often cannot achieve completely uniform mixing of materials within the reactor, resulting in unstable performance of the prepared hierarchical molecular sieve. In addition, during the mixing process, materials tend to settle at the bottom and corners of the reactor, forming mixing dead zones and affecting the mixing effect.

[0004] Therefore, in order to solve the shortcomings of the above problems, a mixing device for preparing multi-level pore molecular sieves is proposed. Summary of the Invention

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0030] like Figure 4 As shown, a mixing device for preparing a multi-level pore molecular sieve comprises: a reactor 1, a mixing mechanism 5 arranged in the reactor 1;

[0031] like Figure 1-Figure 3 As shown, the mixing mechanism 5 includes: a rotating rod 505 and a transmission rod 504, two scraping rods 507 arranged on the outer wall of the rotating rod 505, and two mixing plates 508 arranged on the outer wall of the transmission rod 504;

[0032] One end of the rotating rod 505 is rotatably connected to the circumferential inner wall of the reactor 1. The circumferential outer wall of the reactor 1 is fixedly connected to the motor 501. One end of the output shaft of the motor 501 passes through the reactor 1 and is fixedly connected to one end of the transmission rod 504. The other end of the rotating rod 505 is provided with a transmission groove 511. A slot is provided on one side of the inner wall of the transmission groove 511. One side of the transmission rod 504 is fixedly connected to a first gear 513. One side of the first gear 513 is fixedly connected to an insertion rod 510. The insertion rod 510 is plugged into the slot.

[0033] A transmission assembly is provided in the transmission groove 511, comprising a second gear 514, a plurality of tooth blocks 512 arranged on the inner circumferential wall of the transmission groove 511, the plurality of tooth blocks 512 being fixedly connected to the inner circumferential wall of the transmission groove 511, the second gear 514 meshing with the first gear 513, the second gear 514 being located in the transmission groove 511, and the second gear 514 meshing with the plurality of tooth blocks 512;

[0034] Two mixing plates 508 are fixedly connected to the outer circumferential wall of the transmission rod 504. The two mixing plates 508 are symmetrically distributed. A plurality of through grooves 509 are formed on the upper surfaces of the two mixing plates 508.

[0035] The two scraping rods 507 are fixedly connected to the circumferential outer wall of the rotating rod 505, and the two scraping rods 507 are symmetrically distributed. The circumferential outer wall of the transmission rod 504 is rotatably connected to the sleeve 515. The other ends of the two scraping rods 507 are fixedly connected to the circumferential outer wall of the sleeve 515. The circumferential outer wall of the scraping rod 507 is tightly fitted with the circumferential inner wall of the reactor 1.

[0036] It should be noted that the motor 501 drives the transmission rod 504 to rotate, thereby driving the first gear 513 and the second gear 514 fixedly connected thereto to rotate. Because the second gear 514 meshes with the tooth block 512 in the transmission slot 511, and the first gear 513 engages with the slot in the rotating rod 505 via the insertion rod 510 and transmits torque, the rotating rod 505 also rotates, but in the opposite direction of the transmission rod 504. These opposite rotations create complementary stirring and scraping effects between the mixing plate 508 fixed to the transmission rod 504 and the scraper 507 fixed to the rotating rod 505, effectively improving the uniformity and efficiency of material mixing within the reactor 1. Furthermore, the scraper 507 closely adheres to the circumferential inner wall of the reactor 1, ensuring that the material is fully stirred even near the reactor wall, avoiding material sedimentation and mixing dead zones.

[0037] like Figures 1-4As shown, a same reinforcement plate 506 is fixedly connected between the same sides of the two mixing plates 508, a protective shell 502 is fixedly connected to the circumferential outer wall of the reactor 1, the motor 501 is located in the protective shell 502, and a plurality of heat dissipation holes 503 are provided at the beginning of the circumferential outer wall of the protective shell 502. The reactor 1 is spherical, and the top pipe of the reactor 1 is connected to the feed hopper 4, and the bottom pipe of the reactor 1 is connected to the discharge pipe 3. There are valves on the circumferential outer wall of the discharge pipe 3, and a plurality of support rods 2 are fixedly connected to the bottom of the reactor 1.

[0038] It should be noted that the two mixing plates 508 are fixedly connected on the same side by a reinforcing plate 506, which can enhance the structural strength between the mixing plates 508 and prevent deformation or loosening during high-intensity stirring; the motor 501 is placed in the protective shell 502 to prevent the motor 501 from external impact and pollution during operation, and the heat dissipation hole 503 can ensure good heat dissipation of the motor 501 during operation to prevent overheating; the top feed hopper 4 and the bottom discharge pipe 3 are responsible for the addition and discharge of materials respectively, and are simple to operate and easy to control.

[0039] During use, the present invention introduces material into the reactor 1 through the feed hopper 4. The motor 501 is then started for stirring. The output shaft of the motor 501 is directly and fixedly connected to one end of the transmission rod 504. Therefore, when the motor 501 is started, the output shaft of the motor 501 drives the transmission rod 504 to begin rotating. As the transmission rod 504 rotates, it causes the first gear 513 and the second gear 514 on it to rotate in the opposite direction. The second gear 514 is located within the transmission groove 511 and meshes with several tooth blocks 512 on the inner circumference of the transmission groove 511. As the second gear 514 rotates, it rotates synchronously with the meshing action of the tooth blocks 512, thereby driving the rotating rod 505 to rotate in the reactor 1 in the opposite direction to the transmission rod 504. As the rotating rod 505 rotates, it also causes the two scraping rods 507 on it to rotate together. The other ends of the scraping rods 507 are fixedly connected via a sleeve 515, enabling them to stably scrape the inner circumference of the reactor 1. Simultaneously, the rotation of the transmission rod 504 drives the two mixing plates 508 mounted thereon to rotate in unison. The mixing plates 508, through slots 509 formed therein, shear and disperse the material, achieving a mixing effect. The combined action of the scraper rod 507 and the mixing plates 508 ensures that the material is thoroughly mixed and agitated within the reactor 1. To discharge the material, the valve on the discharge pipe 3 is opened, and the material is discharged from the bottom of the reactor 1 through the discharge pipe 3.

[0040] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
