In the sagger recovery system 200, the sintering device 240 is connected with the sintering line main body 100, when the sintering line main body 100 abnormally operates, for example, when the sintering line main body 100 is idle or stops, the transfer equipment conveys the dried sagger to be processed to the feeding area, and the kiln sinters the anode material in the sagger when the sintering line main body 100 normally operates, so that the sagger recovery system 200 is independent from the sintering line main body 100, and the sintering device 240 is shared by sintering of the sagger to be processed and sintering of the anode material, so that the space occupied by the sintering line 10 is greatly reduced, meanwhile, the sagger is sintered by using heat energy or residual temperature of the kiln when the kiln is idle, the waste of heat energy is avoided, and the problem that the traditional sintering line 10 has more heat energy loss in the idle or stop process is solved.
3. The sagger recovery system 200 modifies saggers based on an impregnation process, monitors the state of each process by using the control systems arranged in each link, adjusts the running state of the sagger impregnation unit in real time, strictly controls the time for the sagger impregnation unit to enter the main unit, and ensures the smoothness of the processes and efficiently utilizes the waste heat of the kiln on the premise of not influencing the main process.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent should be subject to the appended claims.
