Description

Technical Field

[0001] The invention belongs to a prebaked anode carbon block production device, in particular to a prebaked anode carbon block forming machine. Background Art

[0002] Prebaked anode carbon block forming machine is an important equipment for the production of prebaked anode carbon blocks for aluminum. After the calcined petroleum coke is screened and distributed, an appropriate proportion of asphalt is added, and the paste is kneaded and mixed evenly and sent to carbon block mold boxes of different models. The carbon block mold box is placed on the vibration table of the vibration molding machine. After the vibration molding machine vibrates, the paste in the carbon block mold box is continuously reorganized and arranged under the action of the vibration force. After the carbon block is weighed by the vibration molding machine and pressed by the carbon block pressing head, a carbon anode green product is made. At present, the prebaked anode carbon block forming machine is usually a four-column forming machine, and the feeding method usually adopts the parallel feeding method between the middle sides of the two columns of the forming machine, that is, the carbon block pressing head is lifted to the top of the four-column forming machine, and a set of parallel feeding trolleys are installed between the carbon block mold box and the carbon block pressing head. The hot paste is conveyed to the feeding trolley by the hot paste conveying line, and the feeding trolley then feeds the hot paste side parallel to the carbon block mold box. This side parallel feeding method prolongs the feeding time. The hot paste will cause temperature loss during the transportation process, affecting the plasticity of the paste and the quality of the prebaked anode carbon blocks. At the same time, the hot paste will produce a large amount of asphalt fume during the transportation process, which pollutes the surrounding environment of the prebaked anode carbon block forming machine. How to shorten the hot paste feeding time of the carbon block mold box of the prebaked anode carbon block forming machine, reduce the heat loss of hot paste feeding, improve the quality and production efficiency of prebaked anode carbon blocks, and achieve asphalt fume recovery and emission standards are issues that need to be solved.
