Description

Technical Field

[0001] The utility model relates to the technical field of steel metallurgy sintering, in particular to an adjustable stepped material loosener. Background Art

[0002] The iron ore fines sintering process involves segregating and distributing the iron-containing sintering mixture onto the sintering machine trolley. After ignition, the mixture is heated from top to bottom along the height of the material layer using ventilation, and sintered into blocks under incomplete melting conditions. To improve the air permeability of the sintering material layer and enhance sintering quality, multiple layers of horizontal loosening rods are installed below the sintering machine's round roller distributor and at a certain height from the trolley's grate bars. When distributing the material onto the sintering machine trolley, the loosening rods are first buried by the material, which mitigates the impact of falling material and reduces the density of the mixture. When the trolley moves forward, multiple rows of loosening holes are formed in the material layer. As the airflow velocity in the loosening holes and the adjacent areas increases, the air permeability of the sintering material layer is improved.

[0003] Currently, a utility model with publication number CN217058363U discloses a loosening device for sintering machine distribution. The loosening rod is connected to the base via a fixed base plate. When the loosening rod needs to be replaced, it is only necessary to unscrew the fastening bolts on the fixed base plate and pull out the loosening rod to achieve the replacement. In addition, the loosening rod includes a fixed section and a loosening section, and the fixed section and the loosening section are detachably connected. During use, only the loosening section of the loosening rod, which is prone to wear, can be replaced, thereby reducing costs.

[0004] Although the above-mentioned loosening device has certain advantages in disassembly, assembly and replacement, it is not convenient to adjust the spacing of the loosening rods. Sintering mixtures of different particle sizes have different requirements for the spacing of the loosening rods. If the spacing between the loosening rods is too small, it is easy for the sintered mixture to be stuck between the loosening rods. If the spacing between the loosening rods is too large, the loosening of the sintered mixture will be fine and uniform, resulting in poor effect. Utility Model Content

The falling range of the mixture is adjusted according to the distribution range of the loosening rods 3 to ensure that the mixture falls onto the loosening rods 3, thereby increasing the loosening effect of the mixture.

[0030] The adjusting device 5 includes an outer frame 51, a transverse limiting rod 52, a vertical limiting rod 53, a transverse distance changing mechanism 54, a vertical distance changing mechanism 58 and a driving mechanism 59. The ends of the loosening rod 3 are penetrated horizontally and vertically by the transverse limiting rod 52 and the vertical limiting rod 53 respectively. A transverse distance changing mechanism 54 is installed at the top inner top of the outer frame 51.

The inner walls of the loosening rod 3 are in contact with the transverse limit rod 52 and the vertical limit rod 53, so that the loosening rod 3 can slide horizontally and vertically along the transverse limit rod 52 and the vertical limit rod 53 respectively, which is conducive to adjusting the spacing of the loosening rods 3.

[0034] See also Figure 6 The vertical pitch changing mechanism 58 includes a movable plate 581, a guide groove 582, a movable shaft 583, a polished rod 584 and a connecting rod 585. A guide groove 582 is provided on the inner wall of the movable plate 581, and a movable shaft 583 is embedded in the guide groove 582. The movable shaft 583 is slidably connected to the inner wall of the guide groove 582. The movable shaft 583 is fixedly connected to the end of the transverse limit rod 52.

[0035] The number of guide grooves 582 is consistent with the number of transverse limit rods 52, and the spacing of the guide grooves 582 gradually decreases from right to left, so that when the movable plate 581 moves, the movable shaft 583 slides on the inner wall of the guide groove 582, and the spacing of the movable shaft 583 changes, thereby adjusting the spacing of the transverse limit rods 52, that is, adjusting the vertical spacing of the loosening rods 3.

[0036] See also Figure 7 The driving mechanism 59 includes a movable block 591, a bidirectional screw 592 and a second motor 593. There are two movable blocks 591.

[0037] During use, when laying materials onto the sintering machine trolley, the sintering mixture falls through the distributor, and the sintering mixture falls through the distributor blanking frame 1 and the rotating plate 2 to limit the position, and the sintering mixture falls onto the loosening rod 3. The loosening rod is buried by the sintering mixture, which plays a role in reducing the impact force of the falling materials and reducing the density of the mixture; when the trolley moves forward, multiple rows of loosening holes are formed in the material layer. Since the air flow speed in the loosening holes and the adjacent areas is accelerated, the air permeability of the sintering material layer is improved;

[0038] When the spacing of the loose material rods 3 needs to be adjusted, the variable pitch cam shaft 541 is driven to rotate by controlling the motor 1 543. When the variable pitch cam shaft 541 rotates, the vertical limit rod 53 is driven to slide horizontally through the cam groove 542. The bottom end of the moving vertical limit rod 53 drives the slide block 55 to slide horizontally along the guide rail 56 to adjust the horizontal spacing of the vertical limit rods 53. The vertical limit rod 53 drives the loose material rods 3 to slide along the surface of the horizontal limit rod 52 to adjust the horizontal spacing of the loose material rods 3.

[0039] By controlling motor 2 593 to drive the bidirectional screw 592 to rotate, the bidirectional screw 592 rotates and cooperates with the threads between the movable blocks 591 on the left and right sides, driving the two movable blocks 591 to contract or expand, and the two movable blocks 591 respectively drive the connecting rods 585 of the two vertical pitch changing mechanisms 58 to move, and the connecting rods 585 drive the movable plate 581 to move along the light rod 584. When the movable plate 581 moves, the movable shaft 583 slides on the inner wall of the guide groove 582, and the spacing of the movable shaft 583 changes, thereby adjusting the spacing of the horizontal limit rod 52. The horizontal limit rod 52 drives the loosening rod 3 to move vertically along the vertical limit rod 53, adjusts the vertical spacing of the loosening rod 3, and freely adjusts the horizontal spacing and vertical spacing of the loosening rod 3, so as to adjust the spacing of the loosening rod 3 according to the particle size of the sintered mixture, thereby increasing the fine and uniform loosening effect of the sintered mixture.

The wiring diagram of the power element and the provision of power supply are common knowledge in the field. Moreover, the present invention is mainly used to protect mechanical devices. Therefore, the control method and wiring arrangement are not explained in detail in the present invention.

The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.
