3) material suction: the vacuum material sucking device (4) sucks the uniformly mixed raw materials and auxiliary materials in the material mixing tank (3) into each temporary storage tank (5) through the transparent material pipe (7);
4) feeding: the mixed raw materials and auxiliary materials in the temporary storage tank (5) enter a material storage area (33) in a quantitative feeding tank II (6); at the moment, the weight sensor detects the weight of the raw materials and the auxiliary materials in the material storage area (33), after the proper weight in the formula is reached, the electric valve at the bottom of the temporary storage tank (5) is opened, the electric valve at the top is closed, and the vibration device (34) vibrates to promote the raw materials and the auxiliary materials to fall down and finally enter the electrolytic furnace from the inlet (25) of the electrolytic furnace for electrolytic reaction;
5) and (4) alarming: when the pipeline blockage is monitored, the data acquisition and analysis module of the control system acquires and analyzes data, and then the alarm module sends out a short-time alarm signal to prompt the transparent material pipe (7) to be blocked and simultaneously stores the blocked information; if the blockage problem is still not solved after the blockage removing operation is carried out, the alarm module can send out audible and visual alarm, simultaneously an alarm signal is transmitted to the PC end and the mobile end through the signal transmission module, and data are stored until a worker manually resets or the fault is eliminated; the speed sensor constantly monitors the rotating speeds of the stirring rod I (16) and the stirring rod II (19), if the rotating speeds of the stirring rod I (16) and the stirring rod II (19) are lower than a normal value range, the situation that the transmission belt I (14) and the transmission belt II (22) slip or break is indicated, and at the moment, the alarm module can also give an alarm and record alarm data;
6) removing blockage: in the process, the photoelectric sensor constantly monitors the material passing condition of each group of transparent material tubes (7), and if the material is monitored at the inlet of any group of transparent material tubes (7) and no material is detected at the outlet, the middle part of the transparent material tube (7) is blocked; and then the transparent material pipe (7) is vibrated while moving along the track (9) by the movable vibration device (11) corresponding to the transparent material pipe (7), so that the blocked part is vibrated.
