Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] With continuous technological advancements and innovations, the performance and efficiency requirements for pelletizing equipment are also increasing. Against this backdrop, traditional pelletizing machinery often faces a series of challenges, such as low pelletizing efficiency and inconsistent pellet quality. These problems not only affect production efficiency but also increase production costs, thereby impacting the economic benefits of enterprises. To address these challenges, embodiments of this application propose an innovative continuous pelletizing device. The design concept of this device aims to solve at least one or more of the aforementioned problems, thereby significantly improving the efficiency of the pelletizing process. By achieving continuous production, this device can ensure the stability and consistency of pellet output, thus reducing overall production costs. This continuous pelletizing device not only meets the needs of modern industrial production but also plays a significant role in enhancing the market competitiveness of enterprises.

[0028] Specifically, such as Figures 1 to 2 As shown in the figure, this application provides a continuous granulation device, which includes a frame 1, a granulation assembly 2, a feeding device 3, a discharging device 4, and a drive device 5. The granulation assembly 2 is disposed on the frame 1 and is used to form materials into granules; the feeding device 3 is disposed at one end of the granulation assembly 2 and is used to feed materials into the granulation assembly 2; the discharging device 4 is disposed at the other end of the granulation assembly 2 and is used to discharge the formed granules; the drive device 5 is disposed on the frame 1 and is drively connected to the granulation assembly 2, the feeding device 3, and the discharging device 4, and is used to drive the granulation assembly 2, the feeding device 3, and the discharging device 4 to operate.

[0029] In a more detailed description, the embodiments of this application relate to a continuous granulation apparatus, which includes several key components that work together to achieve efficient granulation production. Specifically, the apparatus consists of a frame 1, a granulation assembly 2, a feeding device 3, a discharging device 4, and a drive device 5. The frame 1 serves as the basic structure of the entire apparatus, providing a stable mounting platform for the other components. The granulation assembly 2 is designed and mounted on the frame 1, and its main function is to convert raw materials into the desired granule shape. To ensure a continuous supply of raw materials to the granulation assembly 2, the feeding device 3 is located at one end of the granulation assembly 2, responsible for uniformly and continuously conveying the raw materials into the granulation assembly 2. Meanwhile, the discharging device 4 is located at the other end of the granulation assembly 2, and its task is to promptly discharge the produced granules from the granulation assembly 2, ensuring the smooth operation of the production process. Finally, the drive unit 5 is mounted on the frame 1 and has a precise transmission connection with the pelleting component 2, the feeding device 3 and the discharging device 4. It is responsible for providing power to drive the operation of the entire pelleting equipment and ensuring that all components can work in a coordinated manner to achieve the purpose of continuous and efficient pelleting.

[0030] In one possible implementation, the pelletizing assembly 2 includes: a screw connecting shaft 21, horizontally mounted on the frame 1; and a pelletizing screw 22, mounted axially on the screw connecting shaft 21, for forming pellets from materials under extrusion and shearing action.

[0031] In a specific example of this embodiment, such as Figure 2 As shown, the pelletizing assembly 2 includes a screw connecting shaft 21 and a pelletizing screw 22. The screw connecting shaft 21 is horizontally mounted on the frame 1. The pelletizing screw 22 is mounted on the screw connecting shaft 21 along the axial direction of the screw connecting shaft 21 and is used to form pellets from materials under extrusion and shearing action.

[0032] In an additional example, the pelletizing assembly 2 also includes a hopper (not shown) configured above the screw connecting shaft 21 to receive and convey material downward to the pelletizing screw 22. The front end of the pelletizing screw 22 is typically equipped with cutting blades that cut the extruded material as the screw rotates, thereby forming uniform pellets.

[0033] In one possible implementation, the granulation assembly 2 includes: a first mixing screw 23, which is axially disposed on the screw connecting shaft 21 parallel to the screw connecting shaft 21; and a second mixing screw 24, which is axially disposed on the screw connecting shaft 21 perpendicular to the screw connecting shaft 21; wherein the first mixing screw 23 and the second mixing screw 24 are used to assist the granulation screw 22 in forming materials into granules.

[0034] In a specific example of this embodiment, such as Figure 2 As shown, the pelletizing assembly 2 includes a first mixing screw 23 and a second mixing screw 24. The first mixing screw 23 is arranged parallel to the axial direction of the screw connecting shaft 21 and is tightly connected to the screw connecting shaft 21. The second mixing screw 24 is arranged perpendicular to the axial direction of the screw connecting shaft 21 and is also tightly connected to the screw connecting shaft 21. In this configuration, the first mixing screw 23 and the second mixing screw 24 cooperate to play an auxiliary role, helping the pelletizing screw 22 to more effectively process raw materials or materials through processes such as extrusion and mixing to form the desired pellets.

[0035] To further optimize the granulation process, granulation assembly 2 also includes a heating system that heats both the mixing screw and the granulating screw 22 to ensure the material reaches the appropriate temperature during granulation, thereby improving particle quality and consistency. The heating system can be an electric heater or a steam heater, depending on the characteristics of the material and the required granulation conditions.

[0036] In addition, the pelletizing unit 2 is equipped with a control system that precisely controls key parameters such as screw speed, mixing time, and heating temperature. This control allows the operator to ensure the repeatability and accuracy of the pelletizing process, thereby producing pellets that meet specific specifications. The control system typically includes a user-friendly interface that allows the operator to easily input parameter settings and monitor the pelletizing process in real time.

[0037] In one possible implementation, the pelletizing assembly 2 includes: a connecting sleeve 25 connected to the screw connecting shaft 21 for mounting the screw connecting shaft 21 onto the frame 1; and a screw 26 for locking the screw connecting shaft 21 and the connecting sleeve 25.

[0038] In a specific example of this embodiment, such as Figure 2 As shown, the pelletizing assembly 2 includes a connecting sleeve 25, which is tightly connected to the screw connecting shaft 21. Its main function is to install and fix the screw connecting shaft 21 to the frame 1. In addition, it includes a set of screws 26, which are designed to lock the screw connecting shaft 21 and the connecting sleeve 25, ensuring that they do not loosen, thereby guaranteeing the stability and reliability of the entire pelletizing assembly 2. Preferably, the screws 26 are M2.5x10.

[0039] To further improve the performance and ease of operation of the pelletizing assembly 2, the connecting sleeve 25 may be designed with a specific positioning structure to facilitate the quick positioning and installation of the screw connecting shaft 21. Furthermore, the material selection for the connecting sleeve 25 is crucial; it is typically chosen to be wear-resistant and possess sufficient strength to withstand friction and pressure during prolonged operation. The specifications and material of the screw 26 also require careful selection to ensure that it will not break or deform under high torque.

[0040] In one possible implementation, the feeding device 3 is configured as a feeding screw, which is disposed at one end of the granulation assembly 2 for feeding material into the granulation assembly 2.

[0041] In one possible implementation, the discharge device 4 is configured as a discharge screw, which is located at the other end of the granulation assembly 2 for discharging the formed granules.

[0042] In a specific example of this embodiment, the feed screw is designed and set at one end of the pelletizing component 2. Its main function is to efficiently transport various materials to the pelletizing component 2, ensuring that the materials can enter the pelletizing process smoothly and uniformly.

[0043] Similarly, the discharge screw is also designed and set at the other end of the pelletizing component 2. Its main function is to effectively discharge the processed pellets, thereby ensuring the continuity and efficiency of the entire pelletizing process.

[0044] The feed screw is designed with the material characteristics and required conveying efficiency in mind. It is typically made of wear-resistant materials to withstand prolonged operation and material wear. The feed screw's pitch and diameter are precisely calculated to ensure a stable material flow under various operating conditions.

[0045] The design of the discharge screw is equally important; it needs to match the internal structure of the pelletizing assembly 2 to ensure smooth pellet discharge. The screw's rotational speed and torque can be adjusted according to the size and density of the pellets, thereby optimizing the discharge process and reducing blockages and material residue.

[0046] In one possible implementation, the frame 1 includes: a granulation block 11 disposed near the granulation assembly 2; an upper barrel plate 12 disposed above the granulation assembly 2; a lower barrel plate 13 disposed below the granulation assembly 2; and a pad plate 14 disposed at the lower end of the lower barrel plate 13.

[0047] In a specific example of this embodiment, such as Figure 1 As shown, the design and construction of the frame 1 includes several key components to ensure its functionality and stability. First, the frame 1 includes a pelletizing block 11, which is designed and positioned close to the pelletizing assembly 2 for easy operation and maintenance. Second, an upper barrel plate 12 is positioned above the frame 1, providing additional support and protection for the frame 1. Next, a lower barrel plate 13 is positioned below the frame 1, further strengthening the overall structural integrity of the frame 1. Finally, to ensure the stability and durability of the entire frame 1, a pad plate 14 is placed below the lower barrel plate 13, which not only improves the stability of the frame 1 but also protects the frame from damage.

[0048] Furthermore, the design of frame 1 also considers ease of operation. The tight fit between the pelleting block 11 and the pelleting component 2 ensures smoother material transport, thereby improving production efficiency. The design of the upper barrel plate 12 and lower barrel plate 13 not only considers load-bearing capacity but also ease of cleaning and maintenance, ensuring the long-term stable operation of frame 1. The use of the pad plate 14 further reduces the impact on the frame 1 during equipment operation, extending the service life of frame 1.

[0049] In one possible implementation, the frame 1 further includes a shock-absorbing pad 15 disposed at the bottom of the frame 1.

[0050] In a specific example of this embodiment, such as Figure 1 As shown, the design of rack 1 incorporates additional components to enhance its functionality and stability. Specifically, rack 1 also includes the important component of shock-absorbing pads 15, which are designed and configured in the bottom area of ​​rack 1.

[0051] The shock-absorbing pad 15 is typically made of highly elastic rubber or polyurethane foam to ensure effective absorption and dispersion of impact and vibration from the frame 1. Furthermore, the shock-absorbing pad 15 is simple and convenient to install, and users can easily replace or maintain it as needed.

[0052] In one possible implementation, the drive device 5 includes: a gearbox 51 connected to the granulation assembly 2; a reduction gearbox 52 connected to the gearbox 51; and a servo motor 53 connected to the reduction gearbox 52.

[0053] In a specific example of this embodiment, such as Figure 1 As shown, the drive unit 5 includes several key components that work together to ensure its efficient operation. First, the gearbox 51, as the core of the drive unit 5, is responsible for transmitting power from one component to another. Second, the granulation component 2 is connected to the gearbox 51, receiving power through it and converting it into the specific form required for the granulation process. Furthermore, the servo motor 53, as the power source, is directly connected to the reduction gearbox 52, precisely controlling the output power and speed to ensure the accurate operation of the entire drive unit 5. Finally, the reduction gearbox 52, connected to the servo motor 53, reduces the high-speed rotation output of the servo motor 53, converting it to a lower speed suitable for the operation of the granulation component 2. This improves the efficiency of the entire drive unit 5 and the stability of the granulation process.

[0054] In one possible implementation, the continuous granulation equipment provided in this application embodiment further includes a sealing component 6, the sealing component 6 comprising: a locking block 61 for locking the granulation component 2 onto the frame 1; and a clamp 62 disposed between the granulation component 2 and the driving device 5 for sealing the connection between the granulation component 2 and the driving device 5.

[0055] In a specific example of this embodiment, such as Figure 1As shown, the sealing assembly 6 also includes a sealing ring disposed inside the clamp 62 to ensure a tighter seal between the granulation assembly 2 and the drive unit 5. The sealing ring is typically made of a high-temperature resistant and wear-resistant material to withstand the high-temperature and high-pressure environment that may occur during continuous granulation. In some embodiments, the sealing assembly 6 also includes one or more gaskets placed on the contact surfaces of the granulation assembly 2 and the drive unit 5 to further enhance the sealing effect and prevent material leakage.

[0056] The continuous granulation equipment provided in this application embodiment is designed and configured with granulation components capable of continuous granulation operations. Furthermore, the equipment is equipped with a drive unit responsible for driving the entire equipment to achieve continuous feeding and discharging. This design ensures a continuous supply of materials for the granulation process, guaranteeing that the granulation components can operate continuously. In this way, the continuous granulation equipment not only significantly improves granulation efficiency but also achieves continuous production. The advantages of continuous production lie in its ability to substantially reduce production costs while improving production efficiency and product quality, representing a significant technological advancement for the manufacturing industry. Moreover, this design of the continuous granulation equipment reduces material waste because it allows for more precise control of material usage, thus avoiding the problems of excessive or insufficient material that may occur in traditional intermittent granulation processes. Furthermore, the stability and reliability of the continuous granulation equipment are also improved, as it reduces losses and malfunctions caused by equipment downtime and startup. In summary, the continuous granulation equipment demonstrates significant advantages in improving production efficiency, reducing costs, enhancing product quality, and strengthening equipment stability and reliability.
