Description

Technical Field

[0001] The utility model relates to the technical field of dry quenching coke charging, in particular to a cold coke charging device for a dry quenching coke oven. Background Art

[0002] The CDQ coke oven cold coke loading device is a key equipment in the CDQ system. It is mainly used to load the cooled coke (cold coke) into the coke oven from the top of the CDQ oven. Through the coordinated operation of the automated control system and the CDQ process, it ensures that the cold coke is loaded into the coke oven efficiently and safely, while reducing the emission of dust and harmful gases, improving environmental performance and production efficiency.

[0003] Chinese Patent Publication No. CN220224073U discloses a CDQ cold coke loading device. This device uses a crane to directly lift ton bags of cold coke into a hopper, where it is then transported to the CDQ furnace via a belt conveyor. This significantly reduces mechanical and labor costs and dust generation. Furthermore, the amount of coke discharged from the hopper can be controlled by a gate valve in the hopper, making it faster, more convenient, and more stable, while significantly less dangerous than previous methods. The belt can also be adjusted by setting the number of rollers to accommodate the weight of the cold coke. A tensioning cylinder is used to tension the belt, ensuring that it remains taut for easier transport. However, existing devices use a belt conveyor to load the cold coke. However, during transport, it is difficult to isolate and position the cold coke at the top of the belt, causing it to separate from the belt and fall off, resulting in waste of cold coke resources. Furthermore, it is difficult to level the cold coke at the top of the belt, resulting in accumulation or uneven distribution of the cold coke during transport. This results in uneven cold coke loading into the coke oven, impacting the combustion efficiency and quality of the coke. Utility Model Content
