Description

Technical Field

[0002] During graphite processing, it needs to be roasted and impregnated. Referring to the Chinese patent application number "202121822523.6" "A graphite electrode roasting furnace unloading device", the application points out that when dragging the mobile platform during unloading, the hook pull rod is prone to fall off from the hanging ring, which can easily cause personal injury. When roasting large graphite columns, it is usually hoisted by a crane, and the gaps created by placing the graphite columns are filled with coke particles, and then roasted. The roasting time is It varies with different products, usually fifty days, with the temperature rising for the first twenty-five days and cooling down for the next twenty-five days. After the roasting is completed, the covered coke particles are clamped with a crane hopper, and when the graphite column leaks out, it is trapped with a crane wire rope loop, and pulled up by the crane to the cleaning position for cleaning.
