[0002] The transportation of petroleum coke is an important link in the delayed coking industry. Petroleum coke is irregular block and granular coke, ranging from a few millimeters to more than 200 millimeters. During transportation, due to the unevenness of the material feeding speed and particle size, a discharging machine with a special feeding structure is required for transportation. However, when the discharging machine needs to bend and transport petroleum coke, problems such as material jamming or excessive equipment load often occur, resulting in chain breakage or motor burnout.
[0003] At present, the structure of the curved section of the discharge machine in the prior art is mostly to add a partition in the middle, dividing the curved section trough into two independent spaces, the lower layer is the material conveying layer, and the upper layer is the return chain layer. During use, when encountering larger block materials, they will interfere with the middle partition, and the materials will be stuck in the conveying layer space or directly roll to the upper return chain layer, resulting in a large amount of material accumulation, which requires shutdown for manual cleaning, greatly affecting the conveying efficiency; when the blockage is serious, due to the excessive running resistance of the scraper chain, problems such as chain breakage and chain jamming will occur, causing excessive load on the motor, and then the motor will burn out.
[0004] Some discharging machines also add a sprocket or roller in the middle of the curved section to transport materials.
