Multifunctional Crane for Electrolytic Aluminum

Electrolytic Aluminum Multifunctional Crane Main Function as follows, 

Charging Mechanism

It is used for filling alumina powder and covering materials and for the regulation of materials after filling. It consists of a material box structure, a feeding pipe and a horizontal conveying system.

The material box structure is welded from Q355B steel. It is recommended that the material box be a closed material box. When the factory adds materials to the material box, negative pressure can be generated in the material box to collect dust. The material silo is equipped with an adjustable hydraulic gate valve.

The feeding pipe is a reinforced pipe, which is driven by a hydraulic cylinder and has a foldable nozzle head. The feeding pipe is shared by the alumina silo and the covering silo;

The horizontal conveying system is a screw conveyor structure. After the alumina silo is filled into the tank, the mechanism can directly convey the material in the covering material silo to the feeding pipe to achieve continuous feeding.

Feeding Circulation Mechanism

The main function of multifunctional crane is to collect the covering material before changing the pole, and to add the covering material into the tank after changing the machine. It consists of a sealed material box, a suction pipe, a Roots blower, a bag pulse dust collector, an ash pipe, etc.

Twisting Mechanism

Replace anode carbon blocks and load and unload small box fixtures. It consists of anode fixtures, screw head parts, lifting guide rods, etc.。

1. The anode clamp is a pin-type structure, and its dimensions are interchangeable with the existing clamps. This structure is more accurate and rapid in positioning, helps to achieve automated operation, and can effectively prevent the carbon block from falling.；
2. The screw head is a spline-free direct connection structure, driven by a hydraulic motor. An anti-unhooking device is provided.；
3. The lifting guide rod is driven by a hydraulic cylinder. In order to provide a more stable mechanical structure for automated operation, the shaking amount of the guide rod is controlled to avoid various swings.

Shelling Mechanism

Break up the hard crust around the carbon block.

1. The shell breaking mechanism adopts a four-link mechanism, which can effectively hit the middle seam；
2. The shelling machine guide rod adopts a rectangular steel pipe structure, which has good rigidity and small deformation, which is conducive to automation；
3. The shelling mechanism is folded and driven by double cylinders;；
4. The length of the striking head drill rod is shortened, which makes the working space larger and the slot entry more convenient.

Slag Cleaning Mechanism

Cleaning the residue in the electrolytic cell during pole change
1. The bucket body is made of heat-resistant non-stick stainless steel with a heat resistance of up to 1000°C. The bucket body design and materials prevent residues from sticking to the shell.
2. The lifting mechanism is driven by double cylinders, with longer stroke and more stable movement；
3. The opening and closing cylinder is a self-locking cylinder, which can effectively prevent the grab from opening automatically due to its own weight；
4. The grab can be installed at the silo or on the main swing. When installed at the silo, the grab is equipped with a separate swing mechanism;
