Design and principle of operation
The dispenser-type casting wheel is intended for automatically ladling the molten copper into anodes of defined weight. The molds are being cooled during the motion. The preliminary anode ejection, removal of hardened anodes from the molds, their smooth placement into the cooling tank, alignment of the stubs and spraying the molds with the painting solution occurs when the casting wheel stops for filling.
The driven casting wheel comprises the rotary base and the fixed section interconnected via the rotary roll-type support. The rotary base of the casting wheel features two swiveling devices and 9 molds.
Each mold is installed onto supports used to adjust the horizontal position and fixed in that position with the aid of top clamps.
The casting wheel travels one pitch with the aid of the swiveling device.
The automatic weight proportioner comprises the weighing device and the control system based on the programmable controller, the tundish and the ladle, the hydraulic power station which applies the hydraulic cylinders to rotate the tundish and the ladle.
The cooling water main cools the molds filled with anodes by sprinkling them from above and from below; the system is controlled from the operator booth.
The anode preliminary ejection device is a compound-lever structure with hydraulic actuation.
The anode remover grips the raised anode to its sides with the aid of the pneumatic drive; the rest of the operations (raising the anode from the molds, anode transition and immersion into the tank, sliding anodes on chains inside the tank) are powered by the electrical drives.
The mold painting device comprises the solution tank with the electrically driven mixer and a painting solution application device (featuring spray nozzles).
The machine performs as follows: after all the molds are fully heated and painted, via the spout the molten metal gets from the furnace into the tundish of the weight proportioner; from the tundish it goes into the ladle wherefrom the metal of a defined weight is poured into the mold. After the ladle returns to the initial position a command is issued to rotate the casting wheel one pitch. After the casting wheel stops in the initial position, the next molds are filled in the same manner. Once the casting wheel rotates, the metal gets hardened inside the molds. When the mold with the anode enters the preliminary ejection area, the ejector is triggered and performs preliminary ejection of the anode. Afterwards anode is taken out from the mold with a special remover and is sunk into the cooling tank, and then the cycle is repeated.
When the cooling bath is filled with a defined number of anodes, the anodes are taken out by the workshop load-lifting device and a special gripper and transferred to the section of anode preparation for electrolysis.
