Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of belt conveyor equipment, and particularly relates to a coke conveying belt transfer multi-prong chute device. BACKGROUND

[0002] As an important link of the metallurgical industry, the quality and economic benefits of coke in the production process of a coking plant are closely related. The existing coke conveying equipment usually comprises a feeding belt machine head, a belt feeding port chute connected with the feeding belt machine head, a belt main chute arranged at the outlet end below the belt feeding port chute, and a coke conveying belt machine arranged at the outlet end below the belt main chute. In the transportation link of coke products, the coking plant generally uses multiple coke conveying belts to transport coke from the production area to the total material bin, and then sells the coke products by the way of automobile coke delivery. However, there is a significant technical problem in this transportation process: every time the coke is transferred on the coke conveying belt, it will inevitably be subjected to a beating impact. Since coke itself has a certain brittleness, and its internal structure forms a complex pore structure in the high-temperature coking process, the coke is prone to breakage when subjected to external impact. With the increase of the number of transfers, the coke lump size gradually decreases, and even a large amount of powder is produced. These powders not only cannot meet the requirements of the metallurgical industry for coke lump size, resulting in a decrease in metallurgical coke rate, but also increase the production cost of the coking plant, such as powder cleaning and secondary processing.

[0003] In view of the above problems, although the existing technical means can alleviate the breaking phenomenon of coke to some extent, it does not fundamentally solve the problem of excessive fragmentation of coke caused by beating impact in the transfer process of the coke conveying belt. Therefore, there is now a need for a coke conveying belt transfer multi-prong chute device that can effectively reduce the beating impact of coke during transportation and optimize the transportation conditions of coke.
