Technical Field

The invention mainly relates to the field of electrolytic aluminum pole changing equipment, in particular to a special hopper for changing and feeding an anode of an electrolytic cell.

Background

When the aluminum is prepared by electrolysis of the electrolytic cell, the main component of the anode is a carbon block, the carbon element of the anode is combined with oxygen ions of molten aluminum oxide in the electrolytic cell to generate carbon dioxide, and the whole reaction process is a process of consuming the anode. The carbon anode with the thickness of 700mm can be consumed in about one month and needs to be replaced. At present, the anode is replaced mainly by using a hoisting mode of a crown block, when an old anode is pulled out of an electrolytic tank, a plurality of electrolyte blocks can fall down and fall down to the bottom of the electrolytic tank, and if the old anode is not fished up, a new anode can not fall down. The original solution is that the electrolyte block which is fished by the crane grab bucket is shoveled back to the anode by a shovel, which not only has high labor intensity, but also endures the high temperature of the electrolytic cell and the fumigation of the smoke, and the temperature of the electrolyte block is also higher, thus threatening the health and safety of the operator.

Disclosure of Invention

In order to solve the defects of the prior art, the invention provides the special hopper for replacing and charging the anode of the electrolytic cell, which can replace the operation of shoveling the electrolyte back to the anode by a shovel, and the electrolyte block can be inclined back to the top of the anode by lifting and pulling the electrolytic cell by the cooperation of a crown block, so that the whole process is quick and efficient, the physical burden of operators is reduced, and the injury to the operators caused by high temperature of an electrolytic cell and smoke fumigation is avoided.

In order to achieve the purpose, the invention is realized by the following technical scheme:

electrolytic cell positive pole is changed reinforced special hopper, including hopper shadoof and hopper, hopper shadoof top sets up the shadoof and connects, hopper shadoof bottom sets up first swizzle hole and first fixed pinhole, first swizzle hole is located first fixed pinhole top, hopper one end sets up the connecting rod, set up on the connecting rod with first swizzle hole suited second swizzle hole, with first fixed pinhole suited second fixed pinhole, set up same fixed pin in first fixed pinhole and the second fixed pinhole, set up same swizzle in first swizzle hole and the second swizzle hole, the swizzle can be dismantled in first swizzle hole, second swizzle hole and be connected.

The lifting rod joint is used for being connected with a crown block rope.

The middle part of the connecting rod is provided with a slot, the slot is matched with the bottom of the hopper lifting rod, and the second movable pin hole and the second fixed pin hole penetrate through the slot.

And a pull ring is arranged at the tail end of the loose pin.

Compared with the prior art, the invention has the beneficial effects that:

when the invention is used, firstly, the position of the pole changing groove number is determined, and the hopper is placed at the corresponding pole changing part. And then commanding the crown block to carry out hoisting pole changing operation, commanding the crown block grab bucket to salvage the electrolyte alumina material block in the electrolytic cell after the residual pole is pulled out, and slowly placing the electrolyte block in the pole changing hopper after the crown block grab bucket is fished out. Then a new anode is placed into the anode part of the electrolytic bath by hoisting by a crown block. And finally commanding the crown block to lift the hopper, placing the hopper on the anode steel claw for supporting stress, pulling out the movable pin on the hopper lifting rod, commanding the crown block to lift and lift the lifting hopper, and rotating the hopper around the hinged point of the fixed pin without fixing the movable pin so as to pour the material on the anode. After the operation is finished, the overhead travelling crane falls back, the hopper falls back to the original height, the movable pin is inserted, and the overhead travelling crane lifts the device to the original position and stably puts the device.

According to the invention, the electrolyte block is loaded by the hopper, and can be poured onto the anode at one time by using the matching of the crown block, so that a manual shovel transferring mode is replaced, the whole operation process is quicker, the physical consumption of operators is avoided, meanwhile, the worker is prevented from being roasted and fumigated by the electrolytic bath and the thermal electrolyte block, and the safety and health of the operators are ensured.
