[0022] 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.

[0023] This invention provides a granulation device for testing catalyst activity, such as... Figures 1-3 As shown, the device includes a housing 1, inside which is a crushing chamber 11. A crushing cone 5 is housed within the crushing chamber 11. A drive motor 2 is mounted on the top of the housing 1, and a turntable 21 is mounted on the bottom output shaft of the drive motor 2. An eccentric shaft 22 is mounted on the bottom of the turntable 21. A mold plate 13 is mounted on the inner wall of the crushing chamber 11 near the crushing cone 5. The surface of the mold plate 13 has several small holes, and a feeding bin 12 is located on the back of the mold plate 13. This device includes a housing 1, and the crushing chamber 11 inside the housing 1 provides space for the crushing and shaping of catalyst materials. The crushing cone 5 inside the crushing chamber 11, driven by the drive motor 2, vibrates and compresses through the turntable 21 and the eccentric shaft 22, effectively crushing and compressing the catalyst material. The mold plate 13 mounted on the inner wall of the crushing chamber 11 near the crushing cone 5 has several small holes on its surface, ensuring the size consistency and shape regularity of the catalyst particles. The design of the feeding hopper 12 on the back of the mold plate 13 facilitates the collection and discharge of the catalyst particles after molding.

[0024] In this embodiment, a support 4 is installed on the bottom outer side of the outer casing 1. The support 4 provides stable support for the entire catalyst activity testing granulation device, ensuring the stability and safety of the device during operation.

[0025] Specifically, a feeding trough 3 is installed on the top side of the outer casing 1. The design of the feeding trough 3 allows the catalyst material to be conveniently and quickly added into the crushing chamber 11, improving the feeding efficiency and ease of operation of the device.

[0026] Furthermore, the top end of the eccentric shaft 22 is connected to the eccentric part of the turntable 21. This connection method causes the eccentric shaft 22 to generate eccentric motion under the drive of the turntable 21, thereby driving the crushing cone 5 to vibrate and compress within the crushing chamber 11, achieving effective crushing and shaping of the catalyst material.

[0027] Furthermore, the crushing cone 5 has a conical structure, and its outer wall is provided with helical blades 51. The combination of the conical structure of the crushing cone 5 and the helical blades 51 allows the catalyst material to be subjected to more uniform compression and shearing during the crushing process, thereby improving the uniformity and forming effect of the particles.

[0028] Furthermore, the surface apertures of the mold plate 13 are 3mm-4mm in size. The reasonable aperture design of the mold plate 13 ensures the size consistency and shape regularity of the catalyst particles, meeting the granulation requirements of different catalysts.

[0029] Furthermore, a discharge port 121 is provided at the bottom of the feeding hopper 12, and a valve plate 14 is installed at the discharge port 121. The design of the discharge port 121 and the valve plate 14 allows the formed catalyst particles to be easily discharged from the device, while the valve plate 14 can control the feeding speed, improving the flexibility and practicality of the device.

[0030] Furthermore, the crushing chamber 11 has a conical structure that is larger at the top and smaller at the bottom, and its size is larger than that of the crushing cone 5. This conical structure of the crushing chamber 11 allows the catalyst material to be gradually compressed and shaped during the crushing process, while ensuring the free movement space of the crushing cone 5 within the crushing chamber 11, thereby improving the crushing efficiency and shaping quality of the device.

[0031] The catalyst activity testing granulation device of this invention, in use, firstly includes a shell 1, inside which is a conical crushing chamber 11, wider at the top and narrower at the bottom, providing space for crushing and shaping the catalyst material. Inside the crushing chamber 11 is a conical crushing cone 5, and its outer wall is equipped with helical blades 51 for uniformly compressing and shearing the catalyst material during the crushing process. A drive motor 2 is mounted on the top of the shell 1, and a turntable 21 is mounted on the bottom output shaft of the drive motor 2. An eccentric shaft 22 is mounted on the bottom of the turntable 21, and its top end is connected to the eccentric part of the turntable 21. A mold plate 13 is mounted on the inner wall of the crushing chamber 11 near the crushing cone 5. The surface of the mold plate 13 has several small holes to ensure the size consistency and shape regularity of the catalyst particles.

[0032] A feeding hopper 12 is provided on the back of the mold plate 13, and a feeding port 121 is provided at the bottom of the feeding hopper 12. A valve plate 14 is installed at the feeding port 121 to control the discharge speed of the formed catalyst particles. A bracket 4 is installed on the bottom outer side of the outer shell 1 to provide stable support for the entire device. A feeding trough 3 is installed on one side of the top of the outer shell 1 for convenient and quick addition of catalyst material.

[0033] When the drive motor 2 starts, its bottom output shaft drives the turntable 21 to rotate. The rotation of the turntable 21 is transmitted through the eccentric shaft 22, causing the eccentric shaft 22 to generate eccentric motion. The eccentric motion of the eccentric shaft 22 then drives the crushing cone 5 to vibrate and compress within the crushing chamber 11. The vibration and compression of the crushing cone 5 effectively crushes the catalyst material added to the crushing chamber 11, and the material is uniformly compressed and sheared by the spiral blades 51.

[0034] The crushed catalyst material is extruded through small holes on the surface of the die plate 13 under the extrusion action of the crushing cone 5, forming catalyst particles of uniform size and regular shape. The formed catalyst particles fall into the feeding hopper 12 on the back of the die plate 13. When it is necessary to discharge the catalyst particles, the valve plate 14 can be opened to control the discharge speed of the feeding port 121, so that the formed catalyst particles can be easily discharged from the device.

[0035] Finally, it should be noted that the electronic components in the drive motor 2 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires. The specific connection method should refer to the working order between each electrical component in the above working principle to complete the electrical connection. All of these are technologies known in the art.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
