Description

Technical Field

[0001] The invention belongs to the technical field of screening devices, and in particular relates to a sintered ore mixed multi-stage screening device. Background Art

[0002] Sintered ore refers to a block of ore made by sintering powdered materials, and then obtaining ore products of suitable particle size and removing impurities for subsequent metallurgical processing. During the sintered ore processing, the ore products need to be screened through multi-stage screening equipment to ensure that the particle size composition of the sintered ore meets the requirements of the blast furnace or other smelting equipment, thereby improving smelting efficiency and product quality.

[0003] In the production process of sintered ore, in order to optimize the particle size and improve the efficiency of subsequent processing, the sintered ore often needs to be crushed before screening. This step aims to refine the sintered ore blocks to a particle size that is more suitable for screening, thereby ensuring the smoothness and efficiency of the screening process. However, the current commonly used process is to first crush the sintered ore through special crushing equipment, and then transfer the crushed material to the screening device for grading. This process not only increases the operation links, but may also indirectly affect the overall screening efficiency and the smoothness of the production line due to time consumption and material loss during the transportation process.

[0004] In addition, in the multi-stage screening process, the separation of materials is traditionally achieved by relying on vibrating screens and their built-in vibration motors. However, as the number of screening stages increases, the effective force transmitted by the vibration motor to the screen surface tends to gradually weaken, resulting in poor screening effects, especially when processing fine-grained materials. This not only affects the final quality of the product, but may also increase the difficulty and cost of subsequent processing. Summary of the invention

The support seat 833 is movably connected to one end of the screw 831. The other connecting block 834 is fixedly connected to the bottom end of the sliding seat 82.

[0045] As can be seen from the above, by rotating the screw 831, the screw 831 rotates in the fixed block 832 and moves upward, and at the same time, the screw 831 pushes the support seat 833 movably connected thereto to move upward, and the support seat 833 pushes the connecting block 834 fixedly connected thereto to move, thereby causing the sliding seat 82 to slide in the slide groove 6, and driving one end of the screening plate 81 to move through the sliding seat 82, and at the same time, the other end of the screening plate 81 rotates between the two support blocks 15, thereby adjusting the inclination angle of the screening plate 81.

[0050] As can be seen from the above, after the position of the screening plate 81 is adjusted, the motor 13 can be pushed to slide on the top of the two support frames 12, so that the eccentric wheel 14 is always in close contact with the connecting seat 17, and the motor 13 is started. The output end of the motor 13 drives the eccentric wheel 14 fixedly connected thereto to rotate. Due to the eccentric rotation of the eccentric wheel 14, the eccentric wheel 14 pushes the connecting seat 17 in close contact with it to move, and the connecting seat 17 drives the movable rod 855 movably connected thereto to move, and the movable rod 855 pushes the movable column 851 fixedly connected thereto to slide in the positioning block 852, and when the movable column 851 is displaced, it pulls the movable column 851 fixed thereto The fixed plate 853 connected to it moves, and the fixed plate 853 drives the second spring 854 to extend or contract.

[0054] Embodiment three:

[0055] refer to Figure 8 As shown, one end of the rotating rod 42 is fixedly connected to the output end of the driver 16 .

[0056] As can be seen from the above, the raw material is introduced into the crushing box 41 through the feed port 5, and the driver 16 is started. The output end of the driver 16 drives the rotating rod 42 fixedly connected thereto to rotate, and the rotating rod 42 drives the crushing rod 43 fixedly connected thereto to rotate, and the raw material is crushed by the crushing rod 43. When the rotating rod 42 rotates, it drives the connecting frame 44 fixedly connected thereto to rotate, so that the inner wall of the crushing box 41 is cleaned by the scraper plate 45. The particle size of the raw material after the crushing process is significantly refined, and then it is finely filtered through the connecting net 46 and smoothly enters the guide box 3. Under the guidance of the guide box 3, the raw material is smoothly transported to the screening area where the screening plate 81 is located. The screening process is first started by the second screening mechanism 8, which performs preliminary screening on the raw materials, and introduces the raw materials of different particle sizes into the first screening mechanism 7 and the second material box 10 respectively. The raw materials entering the first screening mechanism 7 are subjected to more detailed screening treatment. Through further screening operations, the raw materials are accurately divided into different particle size levels and introduced into the first material box 9 and the third material box 11 respectively. This multi-stage screening system, with its precise and efficient screening capabilities, ensures that the particle size composition of the sintered ore strictly meets the stringent requirements of the blast furnace or other smelting equipment, and improves the reaction efficiency and product quality in the smelting process by finely controlling the particle size distribution of the raw materials.

[0057] Working principle: rotate the screw 831, the screw 831 rotates in the fixed block 832 and moves upward, and at the same time, the screw 831 pushes the support seat 833 to move upward, and the support seat 833 pushes the sliding seat 82 to move through the connecting block 834, and drives one end of the screening plate 81 to move through the sliding seat 82, and the other end of the screening plate 81 rotates between the two supporting blocks 15, so as to adjust the inclination angle of the screening plate 81, and in this way, the angle of the first screening mechanism 7 is adjusted, and the driver 16 and the motor 13 are started. The output end of the driver 16 drives the rotating rod 42 to rotate, and the rotating rod 42 drives the crushing rod 43 to rotate, and the raw material is introduced into the crushing box 41 through the feed port 5, and the raw material is crushed by the crushing rod 43. The particle size of the raw material after the crushing process is significantly refined, and then it is finely filtered through the connecting net 46 and smoothly enters the guide box 3. Under the guidance of the guide box 3, the raw material is output The raw materials are sent to the screening area where the screening plate 81 is located. Since the output end of the motor 13 drives the eccentric wheel 14 to rotate, the connecting seat 17 is displaced, and the connecting seat 17 drives the movable rod 855 to move. The movable rod 855 pushes the movable column 851 to slide, so that the screening areas of the first screening mechanism 7 and the second screening mechanism 8 vibrate stably. The second screening mechanism 8 first performs preliminary screening on the raw materials, and introduces the raw materials of different particle sizes into the first screening mechanism 7 and the second material box 10 respectively. The raw materials entering the first screening mechanism 7 are subjected to more detailed screening treatment. Through further screening operations, the raw materials are accurately divided into different particle size levels and are respectively introduced into the first material box 9 and the third material box 11, ensuring that the particle size composition of the sintered ore strictly meets the stringent requirements of the blast furnace or other smelting equipment. By finely controlling the particle size distribution of the raw materials, the reaction efficiency and product quality in the smelting process are improved.
