Description

Technical Field

[0001] This utility model relates to the field of pelletizing machine technology, specifically to an adjustable disc for a disc pelletizing machine. Background Technology

[0002] A disc pelletizer is a mechanical device that uses a tilted rotating disc to combine fine-grained powdery materials (such as mineral powder, coal powder, and fertilizer) with a liquid (usually water) through mechanisms such as wetting, nucleation, snowballing, and stratified growth, producing spherical particles of uniform size, strength, and density. It is widely used in industries such as steel, cement, chemicals, and building materials. The disc, a key component of the disc pelletizer, is typically a shallow-bottomed disc with peripheral baffles and forms the core of the pelletizing process. Its tilt angle and rotation speed are adjustable. During pelletizing, the material rolls relative to the disc's baffles along the rotating disc, continuously growing into pellets. Powder deposited at the bottom of the disc is periodically scraped up by a scraper and continues to roll relative to the disc's baffles, further growing into pellets.

[0003] In current technologies, the disc baffles are generally formed into a standard circle, and the size and shape of the pellets are mainly controlled by adjusting the disc's rotation speed and tilt angle. However, only materials that roll relative to the disc during pelletizing will form pellets. The path of materials rolling along the disc baffles is largely limited by the shape of the baffles. Adding mechanisms to the disc baffles may affect the compatibility between the disc and the pelletizing machine. Therefore, current technologies rarely utilize disc baffles, and disc pelletizing machines primarily output spherical materials, offering limited selectivity in terms of pellet size and shape adjustment. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and to make the material rolling path parameters in a disc pelletizer more adjustable, enabling pelletizing effects of different shapes from spheres to ellipsoids, and providing different shape options for pelletizing materials, this invention provides a disc with an adjustable shape for a disc pelletizer.

[0005] This utility model is achieved through the following technical solution: an adjustable disc for a disc pelletizing machine, characterized in that: the adjustable disc consists of a disc base plate, disc flanges, and adjusting screws. The disc flanges form a circular structure, which is then joined with the disc base plate to form the disc structure. Adjusting screws are connected to the four sides of the disc flanges, and the adjusting screws are fixed in bolt holes at corresponding positions on the disc base plate, ensuring a tight fit between the disc flanges and the disc base plate. Through the squeezing action of the left and right adjusting screws and the stretching action of the upper and lower screws, the circular structure of the disc flanges can be transformed into elliptical structures of different curvatures, thus obtaining an adjustable disc structure. Fixing the center of the adjustable disc to the motor rotation shaft of the disc pelletizing machine base yields the disc pelletizing machine with this disc structure.

[0006] Furthermore, the disc flange is made of resilient stainless steel.

[0007] Furthermore, the adjusting screws are connected to the upper, lower, left, and right positions of the circular structure formed by the disc's edge, and are evenly distributed.

[0008] Furthermore, the disc retaining edge can be formed into an elliptical structure of different curvatures by the squeezing action of the left and right adjusting screws and the stretching action of the upper and lower adjusting screws.

[0009] The advantages of this utility model are as follows: 1. This utility model separates the disc base plate and the disc side plate into a disc. They are fixed together by adjusting screws in the corresponding bolt holes on the disc base plate, allowing the disc to be directly assembled onto the base of a standard disc pelletizing machine, resulting in strong adaptability. 2. In this utility model, the disc side plate can be formed into an elliptical structure of varying curvature by the compression of the left and right adjusting screws and the stretching of the upper and lower adjusting screws, thus achieving an adjustable disc structure. The structure is simple and easy to adjust. 3. This utility model provides greater adjustability to the material rolling path parameters in a disc pelletizing machine, enabling pelletizing effects ranging from spherical to ellipsoidal shapes, providing different shape options for pelletizing materials.

[0012] The present invention will now be described in detail with reference to the accompanying drawings.

[0013] A disc-type pelletizing machine uses an adjustable-shape disc, such as... Figures 1-3As shown, this can be implemented as follows: The adjustable disc consists of a disc base plate 1, a disc flange 2, and adjusting screws 3. The disc flange 2 forms a circular structure and is assembled with the disc base plate 1 to form a disc structure. Adjusting screws 3 are connected to the four sides of the disc flange, and the adjusting screws are fixed in the bolt holes 4 at corresponding positions on the disc base plate, so that the disc flange 2 and the disc base plate 1 are tightly connected. By the squeezing action of the left and right adjusting screws 3 and the stretching action of the upper and lower screws, the circular structure of the disc flange 2 can be transformed into an elliptical structure of different curvatures, thus obtaining an adjustable disc structure. Fixing the center 5 of the adjustable disc on the motor rotation shaft of the disc pelletizing machine base yields a disc pelletizing machine with this disc structure.

[0014] In practice, the disc flange 2 is made of elastic stainless steel.

[0015] In practice, the adjusting screw 3 is connected to the upper, lower, left, and right positions of the circular structure formed by the disc baffle 2, and is evenly distributed.

[0016] In practice, the disc retainer 2 can be formed into an elliptical structure with different curvatures by the squeezing action of the left and right adjusting screws 3 and the stretching action of the upper and lower screws.
