Description

Technical Field

[0001] The invention relates to the technical field of material transmission for anode carbon block production, and in particular to spiral unloading, lifting and conveying equipment for calcined coke. Background Art

[0002] In the production of carbon prebaked anodes, petroleum coke that has passed the high-temperature calcination is transported to the subsequent process for roller pressing and grinding. After classification, it forms aggregate calcined coke and powder calcined coke. After adding adhesive and kneading, it enters the molding production. In normal production, the calcination process and the molding process are matched. The petroleum coke is calcined at high temperature in the calcining furnace. The discharge machine is set to automatically discharge with variable frequency. The calcined coke is discharged into a closed vibration conveying system. After processing, classification and kneading, it enters the molding process to produce molded green blocks. The entire production and transportation process is fully closed. Pulse bag dust removal is set to purify the production process and protect the on-site environment of the production operation process. Dust collection ports are set at the material transportation nodes to ensure the dust removal effect. However, in the actual production process, there are production situations where the molding process and calcination process cannot be matched normally. When the calcination capacity of the corresponding calcination and molding process is lower than that of the molding process, it is necessary to purchase calcined coke from other calcination processes or outsource to meet the continuous production of the molding process. When the calcination process and the molding process cannot be matched normally, the calcined coke needs to be transported from other processes by truck. During the unloading of the calcined coke by truck, due to the large and open space, dust is everywhere, and it is difficult to form a closed space. The dust cannot be effectively collected and removed, which seriously affects the production environment. How to realize the closed and automatic continuous unloading of calcined coke by truck, prevent the dust from spreading and overflowing during the unloading process, realize the collection and removal of dust, and protect the on-site environment of the operation process is a problem that needs to be solved.
