[0002] The reference patent title is: A raw material grinding device for catalyst preparation (authorization announcement number: CN222240652U, authorization announcement date: 2024.12.27). It includes a worktable, an adjustment component, a crushing component, a grinding component, a foot column, and a suction cup. By setting the crushing component to first crush the catalyst raw material, the larger particles in the catalyst raw material can be crushed into smaller particles, so that the crushed catalyst raw material is easier to be ground by the grinding component, which can greatly improve the grinding efficiency. By setting the adjustment component, the crushing component can be moved and adjusted to different positions as needed. By setting the grinding component, the catalyst raw material crushed by the crushing component can be ground.

[0003] Based on the above-mentioned documents, the existing raw material grinding devices for catalyst preparation have a relatively simple structure.

In addition, it lacks a scraping structure, and after a long period of grinding work, a lot of raw material tends to adhere to its surface, thus affecting the subsequent grinding quality. Therefore, this utility model provides a raw material grinding device for catalyst preparation. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A raw material grinding apparatus for catalyst preparation includes a base 1, a support shaft 2 rotatably connected to the top of the base 1, a connecting shaft 4 sliding inside the support shaft 2 via a lifting assembly 3, and a grinding mechanism 5 at the top of the connecting shaft 4. The grinding mechanism 5 includes:

[0027] The grinding assembly 51 includes a triangular plate 511 mounted on the top of the connecting shaft 4. A connecting plate 512 is fixedly connected to the bottom of the triangular plate 511. A buffer rod 513 is slidably connected inside the connecting plate 512. A bearing plate 514 is fixedly connected to the bottom of the buffer rod 513. A grinding roller 515 is rotatably connected to the bottom of the bearing plate 514. A buffer spring 516 is fixedly connected to the top of the bearing plate 514. One end of the buffer spring 516 is fixedly connected to the bottom of the connecting plate 512.

[0028] The scraper assembly 52 is disposed on one side of the connecting plate 512;

[0029] Rotating component 53 is located on top of base 1.

[0030] The resistance of the grinding roller 515 during rolling can be buffered by the buffer spring 516 and buffer rod 513; the grinding roller 515 is provided in three sets.

[0031] In this embodiment, the scraping assembly 52 includes a scraper 521. The surface of the scraper 521 is in contact with the surface of the grinding roller 515. A fixing block 522 is fixedly connected to one side of the scraper 521. The surface of the fixing block 522 is slidably connected to the inside of the connecting plate 512. A bolt 523 is threadedly connected to the inside of the fixing block 522. The surface of the bolt 523 is threadedly connected to the inside of the connecting plate 512.

[0032] The scraper 521 can be flexibly disassembled and assembled by means of bolts 523 and fixing blocks 522.

[0033] In this embodiment, the rotating assembly 53 includes a rotating motor 531 mounted on the top of the base 1 and a rotating bevel gear 532 mounted on the surface of the support shaft 2. One end of the output shaft of the rotating motor 531 is fixedly connected to the rotating bevel gear 533 through a coupling, and the surface of the rotating bevel gear 533 meshes with the surface of the rotating bevel gear 532.

[0034] The rotating motor 531 is a three-phase asynchronous motor and is connected to an external circuit via wires.

[0035] In this embodiment, the lifting assembly 3 includes a lifting motor 31 installed inside the support shaft 2. One end of the output shaft of the lifting motor 31 is fixedly connected to a lifting screw 32 via a coupling. The surface of the lifting screw 32 is threadedly connected to the internal thread of the connecting shaft 4.

[0036] The lifting motor 31 is a three-phase asynchronous motor and is connected to an external circuit via wires.

[0037] With the lifting assembly 3 installed, the height of the connecting shaft 4, triangular plate 511, bearing plate 514 and grinding roller 515 can be flexibly adjusted by the lifting motor 31. This allows the grinding roller 515 to be quickly separated from the grinding tank 8 when collecting the ground catalyst raw materials, facilitating material handling.

[0038] In this embodiment, a symmetrical limiting rod 6 is fixedly connected to the top of the support shaft 2, and the surface of the limiting rod 6 is slidably connected to the inside of the connecting shaft 4.

[0039] The limiting rod 6 is used to limit the up and down sliding of the connecting shaft 4.

[0040] In this embodiment, a grinding disc 7 is fixedly connected to the top of the base 1, and a grinding groove 8 is provided on the top of the grinding disc 7. The inner surface of the grinding groove 8 is in contact with the surface of the grinding roller 515.

[0041] With the rotating component 53, the three sets of grinding rollers 515 are driven by the rotating motor 531 to circulate and roll inside the grinding tank 8. The three sets of grinding rollers 515 are used to grind the catalyst raw materials. At the same time, the buffer rod 513 and the buffer spring 516 are provided to ensure that the grinding rollers 515 can get a good buffering effect during the rolling process, thereby improving the service life of the device. Furthermore, the flexible detachable scraper 521 can scrape off the raw materials adhering to the surface of the grinding rollers 515 during the grinding process, preventing excessive raw material powder from adhering to the surface of the grinding rollers 515, thereby improving the grinding quality.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] During operation, the raw materials for catalyst preparation to be ground are first placed in the grinding tank 8. Then, the rotating motor 531 drives the rotating bevel gear 533 to rotate. The rotation of the rotating bevel gear 533 causes the rotating bevel gear 532, support shaft 2, connecting shaft 4, triangular plate 511, and grinding roller 515 to rotate synchronously, so that the three sets of grinding rollers 515 roll inside the grinding tank 8. The grinding rollers 515 grind the catalyst raw materials. During the grinding process, the buffer rod 513 and the buffer spring 516 can buffer the grinding rollers 515 during the grinding process to prevent them from rolling. Due to the high resistance, the device may be damaged. At the same time, the scraper 521 installed can scrape the surface of the grinding roller 515 to prevent the catalyst material from adhering to the surface of the grinding roller 515 and affecting the grinding quality. Finally, after the grinding work is completed, the lifting motor 31 is started to drive the lifting screw 32 to rotate. The rotation of the lifting screw 32 will cause the connecting shaft 4, the triangular plate 511 and the grinding roller 515 to slide upward synchronously, so that the connecting shaft 4 slides on the surface of the limiting rod 6, and the grinding roller 515 is separated from the grinding tank 8, which makes it easier to collect the ground catalyst material.
