Problems solved by technology

This is only one aspect; on the other hand, after the electrolyte sucked into the ladle is poured into the mixing furnace of the casting department together with the metal aluminum liquid, it will not only increase the cleaning workload of the electrolyte in the mixing furnace, but also speed up the mixing furnace. Lining damage
Especially with the increase of the volume of the ladle, each ladle needs to absorb the aluminum liquid of 3 to 4 electrolytic cells at a time, which also increases the total amount of electrolyte sucked in the ladle
Although this problem has caused headaches for operators for a long time, it seems that technicians have not paid enough attention to it

Embodiment 1

[0019] Example 1 Electrolyte operated anti-electrolyte inhalation device

[0020] In front of the mouth of the aluminum suction tube 1, a blocking plate 6 is set, and more than two pull rods 3 are installed on the edge of the blocking plate at the outer edge of the aluminum suction tube, and more than two sets of pull rod brackets 5 are installed on the outer wall of the aluminum suction tube. A group bracket consists of more than two brackets. Pull rod passes pull rod support, and it is near the root of suction aluminum bag 8, and car has the external thread that cooperates with drive unit 2 internal threads. The bottom of the blocking plate is also provided with a positioning rod 4, which further ensures that the pull rod can slide back and forth in the pull rod bracket smoothly, and promotes the opening and closing of the blocking plate.

Embodiment 2

[0021] Example 2 Manually Operated Electrolyte Inhalation Prevention Device

[0022] In front of the mouth of the aluminum suction pipe 1, a blocking plate assembly 7 is arranged, and the blocking plate 6 itself is arc-shaped, and matched with this, the side of the aluminum suction pipe mouth is also arc-shaped, and the curved surfaces of the two match everywhere. The blocking plate assembly is provided with a blocking plate rotary shaft 9, with the rotary shaft as the center, a pull rod 3 is arranged on the other side opposite to the center of gravity of the blocking plate assembly; and more than one sliding bracket 5 is provided on the outside of the aluminum suction tube. Covered in the bracket, the other end is provided with a handle 11 and a handle rotary shaft 10 which are hinged with it. When the handle is moved, the pull rod moves forward and backward with the handle rotary shaft as the axis, and then the blocking plate assembly is driven around The rotary shaft of the...

Embodiment 3

[0023] Example 3 Anti-electrolyte inhalation device for automatic operation

[0024] In front of the aluminum suction pipe 1, a rectangular blocking plate 3 is set, and the corresponding front end section of the suction pipe is also changed into a rectangle. Blocking plate and the thick splint welded on its both sides form reversible blocking plate assembly 7, splint itself is the gravity push plate 12 that profile is arc, and eccentric rotary shaft sleeve 13 is arranged on the push plate. And be equipped with rotary shaft 9 at suction pipe outer wall. Usually, the blocking plate assembly rotates around the rotary shaft under the action of eccentric gravity to close the suction pipe; when aluminum is to be tapped, although the suction pipe enters the electrolyte layer, the blocking plate assembly is still closed under the action of eccentric gravity because the gravity push plate has not touched the bottom of the tank Nozzle. When the suction pipe continues to descend throug...

Abstract

A method for preventing electrolyte intake in aluminum ladle is provided, which comprises blocking the port of the suction pipe with a special device before the aluminum suction pipe is inserted into the melt in the electrolytic bath, operating the device to open the port after the suction pipe is inserted into the aluminum electrolyte, and blocking the port again when the suction pipe is extracted from the aluminum electrolyte. A device for implementing the method is also provided, which comprises a ladle and an aluminum suction pipe. The device is characterized in that a blocking plate for blocking the suction pipe and a blocking plate driving unit are arranged in front of the ladle and the aluminum suction pipe, wherein the blocking plate is round or square and works in sliding or turning mode. The device can prevent the electrolyte intake in the aluminum ladle or at least reduce the quantity of electrolyte inlet in the aluminum ladle, and helps to prolong the service life of ladle and mixing furnace and to improve the quality of electrolytic aluminum.

Description

technical field [0001] The invention belongs to the technical field of supporting equipment for an aluminum electrolytic cell, and in particular relates to a method and a device for carrying out an aluminum ladle to prevent electrolyte inhalation. Background technique [0002] The liquid metal aluminum produced by the electrolysis of the aluminum electrolytic cell must be regularly sucked out by the aluminum ladle and transported away with a straw. Because the melt in the electrolytic cell is divided into upper and lower layers, the upper layer is the molten electrolyte, and the lower layer is the liquid metal aluminum. Before the ladle straw enters the aluminum liquid layer, it must first pass through the electrolyte layer. As a result, some molten electrolyte will always be sucked into the straw first. Since the viscosity of the electrolyte is greater than that of the aluminum liquid and the freezing point is low, the electrolyte is easily solidified and scarred on the in...
