Description

Technical Field

[0001] The utility model relates to the field of iron-carbon coke preparation, in particular to a mixing and tamping device for iron-carbon coke preparation. Background Art

[0002] In the production of iron-carbon coke, the coal sieve is a key component for coal loading. The effective utilization of its internal space and the compactness of the coal charge have a crucial impact on the quality of the final coke. However, in actual operation, an often overlooked problem is that the space inside the coal sieve often increases undesirably after the tamping process.

[0003] This phenomenon is mainly caused by the following factors: First, the particle size and shape of the raw coal vary greatly, making it difficult to form a tight stack during initial filling, and there are a large number of gaps; second, although some coal can be compacted during the tamping process, due to the limitations of tamping force, method and coal characteristics, these gaps are often unable to be completely eliminated; finally, the vibration and impact force generated during the tamping process may cause the coal to rearrange, forming larger spaces or voids.

[0004] The increased internal spaces in the coal slag after tamping not only waste valuable coking coal resources and increase production costs, but more importantly, these spaces become channels for gas to escape during the subsequent carbonization process, affecting the density and strength of the coke, thereby reducing the overall quality of the coke. Furthermore, the increased spaces can lead to uneven distribution of hot air within the coke oven's carbonization chamber, affecting thermal efficiency and potentially exacerbating wear and aging of the coke oven.

[0005] Therefore, it is necessary to provide a new mixing and tamping device for preparing iron-carbon coke to solve the above technical problems. Utility Model Content

[0013] Preferably, a cylinder is fixedly connected to one side of the bracket, and an output end of the cylinder is fixedly connected to the movable frame.

[0014] Compared with the related art, the mixing and tamping device for preparing iron-carbon coke provided by the utility model has the following beneficial effects:

[0015] Significantly improves filling capacity: During the rotating discharge process of the mixing tank, the connecting disc and the T-shaped impact rod continuously vibrate. This vibration effectively promotes the mutual friction and rearrangement of coal particles, making the coal more tightly packed in the coal sieve, thereby significantly improving the filling capacity and reducing gaps and unfilled areas.

[0016] Optimize coal distribution: Vibration makes the coal more evenly distributed in the coal sieve, avoiding the uneven accumulation problem caused by differences in coal particle size and shape in traditional methods. This helps to form a more compact coal cake during the subsequent tamping process, improving the quality of the coke.

[0017] Enhanced tamping effect: During the tamping stage, since the coal has been initially and tightly arranged by vibration, the tamping rod can more easily penetrate the coal layer during tamping, achieving a more uniform compaction effect. This not only reduces energy loss during the tamping process, but also improves tamping efficiency, ensuring the density and strength of the coke.

[0018] Improved production efficiency: Due to the significant improvement in filling capacity and tamping effect, the efficiency of the entire iron-carbon coke preparation process has also been improved. This reduces rework and downtime caused by incomplete filling or uneven tamping, and improves equipment utilization and the overall production capacity of the production line.

[0019] Reduced energy consumption and costs: By optimizing the coal loading and tamping processes, energy waste caused by gaps and unfilled areas is reduced, lowering production costs. At the same time, the automation and stability of the equipment are improved, reducing manual intervention and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

The shift block 36 is fixed to the connecting disk 6 in the yard away from the center of the circle.

[0030] The working principle of the mixing and tamping device for preparing iron-carbon coke provided by the utility model is as follows:

[0031] Initial state: Mixing tank 5 is located away from coal sieve 3, mobile frame 4 is supported on support 1 by cylinder 12, L-shaped insert 38 is in a retracted state and does not contact coal sieve 3; mixing tank 5 has been pre-loaded with iron-carbon coke raw materials and is ready for mixing;

[0032] Mixing process: The motor 21 is started, and the output end of the motor 21 is fixedly connected to the driving gear 22, which drives the ring gear 23 to rotate, thereby driving the mixing tank 5 to rotate, achieving uniform mixing of the raw materials; at this stage, the movable frame 4, the L-shaped insert plate 38 and the coal sieve 3 all remain in place;

[0033] Discharge preparation and activation of the L-shaped insert 38: After mixing is completed, the system enters the discharge preparation stage; the cylinder 12 pushes the movable frame 4 to bring the mixing tank 5 close to the coal sieve 3, while the L-shaped insert 38 moves together and inserts into the bottom of the coal sieve 3; the corner bars 39 on the L-shaped insert 38 lift the coal sieve 3, making it unstable; this unstable state provides favorable conditions for subsequent vibration;

[0034] Enhanced discharge and vibration: When the mixing tank 5 reaches the predetermined position, the discharge port opens and the motor 21 runs in the reverse direction, causing the iron-carbon coke raw materials in the mixing tank 5 to fall into the coal sieve 3. At this time, since the coal sieve 3 is in an unstable state due to the support of the L-shaped insert plate 38, and the vibration generated by the rotating disk and the T-shaped impact rod 7 during the discharge of the mixing tank 5, the raw materials in the coal sieve 3 will be subjected to a stronger vibration effect. This vibration helps to eliminate gaps between the raw materials and improve the packing density.

[0035] Tamping process: As the raw materials are continuously added, the coal slurry 3 is gradually filled. When the predetermined height is reached, the discharge stops. At this time, the tamping rod starts to work, and the raw materials in the coal slurry 3 are evenly compacted by repeated lifting and lowering. Because the coal slurry 3 has been lifted up and vibrated by the L-shaped insert 38 in the early stage, the gaps between the raw materials have been greatly reduced, so the tamping process will be more efficient and the formed coal cakes will be more dense.

[0036] Completion and reset: After tamping is completed, the tamping rod, L-shaped plug plate 38 and movable frame 4 and other components are reset to the initial state in sequence; at this time, the coal sieve 3 has been filled with dense iron-carbon coke raw materials and is ready for subsequent coking treatment.

Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
