Description

Technical Field

[0001] The invention relates to an automatic online carbon bowl filling device for prebaked anodes, belonging to the technical field of carbon anode production equipment. Background Art

[0002] At present, in the processing operation of prebaked anodes by high-temperature roasting of carbon anodes in a roasting furnace, the roasting operation is easy to cause the filler in the carbon bowl to soften and migrate due to the increase in temperature, which leads to the collapse of the filler in the carbon bowl, resulting in voids in the middle of the filler, collapse on the upper surface of the carbon bowl, and other serious effects on the quality of the anode product. In response to this problem, there is currently no effective equipment that can continuously perform raw material filling operations. Although there are many types of filling equipment currently developed, material filling operations can often only be performed under low temperature conditions. However, since the materials in the carbon bowl are in a high temperature state when they collapse, and the collapse and cavity defects cannot be found under the low temperature operation state, it is often difficult for operators to approach to perform material replenishment operations. At the same time, even if the collapse layer on the surface of the carbon bowl can be filled by manual means, the void defects inside the filler in the carbon bowl due to collapse cannot be effectively repaired, resulting in a large number of cavities inside the carbon bowl, and ultimately resulting in carbon bowl defects and other waste products after roasting.

[0003] In addition, the traditional carbon anode carbon bowl filling is often done manually, which has low work efficiency, heavy workload, high labor intensity and great safety hazards.

[0029] During operation, the raw materials configured by the mixing mechanism are transported to the guide pipe, and then transported to the anode carbon bowl on the horizontal driving mechanism below through the guide pipe. The guide pipe is set as an inverted truncated cone-shaped funnel structure to improve the efficiency and accuracy of filling the material into the carbon bowl and prevent material leakage. At the same time, during the filling process, on the one hand, the material is preheated by the electric heater to prevent the material from migrating in the carbon bowl due to the high temperature during subsequent roasting; on the other hand, the driving nut and the driving motor are used to effectively adjust the working height of the driving rod, and the downward pressure of the driving rod is used to compact the filling material filled in the carbon bowl to eliminate defects such as gaps and cavities in the filling material.
