[0002] As the self-baking electrode material of submerged arc furnace, electrode paste is a conductive material for electric furnace equipment such as ferroalloy furnace and calcium carbide furnace. It has been widely used in the smelting of various products in submerged arc furnace. , the electrode is gradually consumed, and a certain amount of electrode paste needs to be added at intervals to meet the normal production needs. At present, the electrode paste is added to the submerged arc furnace by manual use of shovels, shovels and other tools to shovel the electrode paste into the material barrel, and then Manually assisted electric hoist lifts the barrel above the electrode cylinder to add electrode paste to the electrode cylinder. The manual operation has the disadvantages of large workload, high risk factor, and low productivity, and there are many potential safety hazards. The electrode paste device takes up a lot of space and is usually installed far away from the submerged arc furnace, which consumes a lot of human resources in the transportation process. The production process of the submerged arc furnace has gradually become large-scale, automated, and intelligent. The existing electrode paste The method is far from meeting the production needs, so the intelligent and efficient method of adding electrode paste will gradually replace the manual method

[0003] Chinese patent document CN2013205186760 discloses a hollow electrode charging device for a submerged arc furnace. The device passes through a feeder and a hopper installed at the feeding end of the feeder, and the outlet end of the feeder is connected to a flexible feeding pipe, a nitrogen delivery sealing device, The electrode barrels are connected in sequence to provide a feeding device that can automatically fill electrode paste. This device improves the utilization rate of raw materials, is flexible in operation, convenient in maintenance, and simple in structure. However, this device still has some disadvantages: it cannot Furnace filling, the filling efficiency is low; the electrode paste of the remote storage device cannot be automatically filled into the electrode cylinder, and the space utilization rate of the site is low; the degree of automation is low, and some processes still need manual operation, which cannot be completely eliminated. change
