Description

Technical Field

[0001] This utility model relates to the field of sintering flux production technology, specifically to a grinding and granulation device for sintering flux production. Background Technology

[0002] In the production of sintered flux, the raw materials need to be ground, dispersed, blended and granulated by a grinding and granulation device to obtain qualified particles or granules, and obtain flux particles with particle size, shape, density and chemical homogeneity that meet the requirements of sintering and welding processes.

[0003] For example, Chinese Patent CN223010475U discloses a grinding and granulation device for the production of sintered flux, including a grinding cylinder, a sieving cylinder, and a discharge port. The sieving cylinder is welded to the bottom of the grinding cylinder, and two sets of discharge ports are symmetrically positioned on the outer surface of the sieving cylinder. A granulation mechanism is installed inside the grinding cylinder, and a sieving mechanism is installed inside the sieving cylinder. The granulation mechanism includes a support plate, a grinding plate, a granulation plate, a drive motor, a support rod, a grinding column, and an extrusion column. The support plate, grinding plate, and granulation plate are welded to the inner surface of the grinding cylinder. In this grinding and granulation device for the production of sintered flux, the grinding column extrudes and grinds large particles of sintered flux into small particles. When the extrusion column rotates, it extrudes and granulates the ground sintered flux through circular holes on the inner side of the granulation plate. Through the grinding of the sintered flux by the grinding column and the extrusion of the sintered flux by the extrusion column, the sintered flux particles are made smaller, resulting in more uniform granulation of the sintered flux.

[0004] Existing sintering flux production equipment is prone to agglomeration after material grinding, which affects its subsequent processing flow. Furthermore, sintering flux production equipment often focuses on a single function and lacks an efficient integrated grinding and granulation mechanism. Utility Model Content

[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] Example 1: Please refer to Figures 1 to 6 The present invention provides the following technical solution:

[0026] A grinding and granulation device for producing sintering flux includes a main shaft 1 installed inside a housing. Grinding components and granulation components are arranged sequentially on the outer side of the main shaft 1. The grinding components include a rotating block 2 fixedly connected to the middle section of the main shaft 1. The rotating block 2 has a conical structure. Uniformly distributed crushing teeth 3 are fixedly connected to the outer side of the rotating block 2. A crushing chamber is formed between the outer side of the rotating block 2 and the inner side of the housing. A radially distributed mounting shaft 4 is fixedly connected to the bottom of the rotating block 2. A grinding roller 5 is rotatably connected to the outer side of each mounting shaft 4. A grinding chamber is formed between the bottom of the rotating block 2 and the housing.

[0027] The housing includes a feeding hopper 6, a conveying pipe 7 is fixedly connected to the bottom of the feeding hopper 6, a processing pipe 8 is slidably connected to the bottom of the conveying pipe 7, a granulation pipe 9 is provided at the bottom of the processing pipe 8, a bracket 12 is fixedly connected to the inner side of the top of the feeding hopper 6, a motor 13 is fixedly connected to the middle of the top of the bracket 12, and the output end of the motor 13 is connected to the top of the main shaft 1.

[0028] The upper end of the rotating block 2 is located inside the conveying pipe 7, and the lower end of the rotating block 2 is located inside the processing pipe 8. A crushing chamber is formed between the outer side of the rotating block 2 and the inner side of the processing pipe 8, and the crushing teeth 3 are located in the crushing chamber. A grinding screen plate 10 is provided at the separation point between the processing pipe 8 and the granulation pipe 9. The grinding screen plate 10 is in contact with the bottom of the grinding roller 5, and a grinding chamber is formed between the bottom of the rotating block 2 and the top of the grinding screen plate 10. The bottom of the rotating block 2 and the grinding screen plate 10 are both inverted conical structures that match each other. The bottom cross section of the granulation pipe 9 is a U-shaped structure. The bottom of the granulation pipe 9 is provided with annular and evenly distributed forming holes 11. The main shaft 1 passes through the grinding screen plate 10 and is located at the center of the annular distribution of the forming holes 11.

[0029] The granulation device includes connecting shafts 14 fixedly connected to both sides of the lower end of the main shaft 1. A pressure roller 15 is rotatably connected to the outside of the connecting shaft 14. The bottom of the pressure roller 15 matches and fits against the bottom of the granulation tube 9. A turntable 16 is fixedly connected to the lower end of the main shaft 1. The turntable 16 is located outside the shell and fits against the bottom of the granulation tube 9. The turntable 16 has annular and evenly distributed pelletizing holes 17 inside. The pelletizing holes 17 correspond one-to-one with the forming holes 11, and the inner cross section of the pelletizing holes 17 is triangular.

[0030] When the device is started, the motor 13 is powered on and drives its output end to rotate, thereby driving the main shaft 1 to rotate around its axis. The rotational motion of the main shaft 1 is transmitted to the rotating block 2 fixedly connected to its middle section, so that the rotating block 2 rotates together with the main shaft 1. The material is fed from the feed hopper 6 and falls into the conveying pipe 7 under the action of gravity, and enters the crushing chamber formed between the outer side of the rotating block 2 and the inner side of the processing pipe 8. In the crushing chamber, the conical structure of the rotating block 2 generates centrifugal force, which throws the material outward toward the inner side of the processing pipe 8. At the same time, the crushing teeth 3 fixed to the outer side of the rotating block 2 rotate with the rotating block 2, impacting and shearing the material to achieve preliminary crushing. The crushed material moves downward under the action of gravity and enters the grinding chamber.

[0031] Inside the grinding chamber, the mounting shaft 4 at the bottom of the rotating block 2 rotates with the main shaft 1, causing the grinding rollers 5 connected to the outside of each mounting shaft 4 to rotate around the axis of the mounting shaft 4. Under the action of centrifugal force, they come into contact with the top of the grinding screen plate 10. Since the bottom of the rotating block 2 and the grinding screen plate 10 are both inverted conical structures that match each other, the material slides down the conical surface under the action of gravity and is crushed and ground by the grinding rollers 5. The grinding rollers 5 roll on the grinding screen plate 10 to further refine the material. The fine powder falls into the granulation tube 9 below through the screen holes of the grinding screen plate 10, while the coarse material continues to be ground.

[0032] In the granulation tube 9, the material gathers at its bottom U-shaped structure. The connecting shaft 14 at the lower end of the main shaft 1 rotates with the main shaft 1, driving the lower pressure roller 15 to rotate around the axis of the connecting shaft 14. The bottom of the lower pressure roller 15 is in contact with the bottom of the granulation tube 9, applying pressure to the material during rotation and pressing the material into the annularly distributed forming holes 11 at the bottom of the granulation tube 9 to form strip-shaped particles. At the same time, the turntable 16 fixed at the lower end of the main shaft 1 rotates with the main shaft 1, and the pelletizing holes 17 on it correspond one-to-one with the forming holes 11. When the material is extruded from the forming holes 11, the rotation of the turntable 16 causes the edge of the triangular cross section of the pelletizing hole 17 to contact the extruded material, using shearing action to cut the strip-shaped material into uniform particles. Finally, the particles are discharged from the bottom of the granulation tube 9, completing the entire grinding and granulation process.
