Description

Technical Field

[0001] The utility model relates to the technical field of coking material distribution and storage, in particular to a bridge-type overhead crane coking distribution system. Background Art

[0002] Coke is a solid, carbonized substance obtained by distilling coal under high-temperature, oxygen-free conditions. As an indispensable raw material, coke is widely used in steelmaking. Coke acts as a reducing agent, participating in metallurgical reactions and ultimately forming high-quality steel. Without coke, the smelting process cannot be completed, impacting the overall process flow. Therefore, coke plays a crucial role in the steel industry. Beyond the steel industry, coke is also widely used in a variety of fields, including the aluminum, carbon, and silicon industries.

[0003] Currently, coke distribution within coking industry silos or enclosed coke yards is typically done via conventional belt conveyor heads, reversible belt conveyors, or unloading trucks. While these distribution systems offer advantages such as high throughput, reliable operation, simple structure, and ease of maintenance, they are limited to point or line distribution. Due to the coke accumulation angle, they are unable to effectively utilize the available space, resulting in low coke storage capacity per unit area.

[0004] While some distribution equipment, such as stackers and reclaimers, can achieve surface distribution, offering advantages such as greater effective spatial volume and higher coke storage capacity per unit area, stackers and reclaimers are complex and difficult to maintain. This, especially for closed coke yards with smaller coke reserves, also results in high storage costs per ton of coke. Utility Model Content

The discharge port of the rack-type unloading car 2 and the inlet of the enclosed belt conveyor 3 are connected with rubber or other flexible materials. The rack-type unloading car 2 delivers coke directly into the enclosed belt conveyor 3. The enclosed belt conveyor 3 is driven by a tail pulley 31 at the right end, and a spiral tensioning device is located at the head pulley 32 at the left end.

[0040] A Y-direction track is provided at the lower part of the interior of the bridge type overhead crane 5. The Y-direction track is a closed reversible moving belt conveyor running track 51. The closed reversible moving belt conveyor 4 is installed on the closed reversible moving belt conveyor running track 51 and moves along the Y-direction of the closed reversible moving belt conveyor running track 51.

[0041] The exterior bottom of the overhead crane 5 is equipped with a Y-direction track. This track serves as the coke collection and dust collection device track 52. The coke collection and dust collection device 7 is mounted on this track and moves along it in the Y direction. A hole running longitudinally (in the Y direction) is located in the center of the track, with a grate 53 positioned above it.

The telescopic ventilation duct 102 ensures that the dust collecting hood 7 can be moved to any position and the dust collecting hood 7 can be connected to the vehicle-mounted dust collector 8 through the lower dust collecting ventilation duct 10.

[0048] The working principle and working process of this utility model are as follows:

[0049] Coke enters the coke field via belt conveyor 1 and then enters enclosed belt conveyor 3 via rack-type unloader 2. From enclosed belt conveyor 3, coke enters enclosed reversible belt conveyor 4 and is finally distributed to the enclosed coke field through the coke distribution port of enclosed reversible belt conveyor 4. Coke distribution is achieved along the coke field length (X) by means of an overhead crane 5 traveling along an X-track, and along the coke field width (Y) by means of the enclosed reversible belt conveyor 4 traveling along a Y-track. Coke distribution is achieved in both the X and Y directions, thus achieving surface distribution.

[0050] The utility model can realize surface distribution inside the closed coke field, has the advantages of large effective utilization of space volume and high coke storage capacity per unit area; the structure is simple, the width span of the operating workshop is small, the top height is moderate, maintenance is not difficult, and the storage cost per ton of coke is low.
