Description
Technical Field
The invention relates to the field of electrolytic aluminum, in particular to an aluminum electrolytic cell cover system and an aluminum electrolytic cell device.
Background
At present, the metal aluminum is obtained by a cryolite-alumina fused salt electrolysis method, and due to the particularity of the production process, a large amount of dust and electrolysis flue gas (CO) exist in the electrolysis process2HF gas, SO2Etc.) to escape from the electrolytic bath, cause pollution to production workshops and surrounding environment, and in order to reduce pollution and purify production environment, a bath cover plate is arranged on the electrolytic bath to prevent dust and smoke from escaping. The tank cover plates are placed and covered on the electrolytic tank in series connection sequence, each tank can be independently opened, closed and moved away by manual operation, and the tank cover plates have the functions of preventing pollutants from escaping, maintaining the negative pressure balance of gas collection in the tank, preventing foreign matters from falling into the tank, protecting the safety of personnel in a workplace, preserving the temperature of the tank body and the like.
At present, the opening and closing of the tank cover plate are manually operated by field operators. For the convenience of the operators, the cell side cell cover plates are usually designed as light and thin aluminum sheets. Such a light and thin slot cover plate has problems of low mechanical strength and large heat dissipation loss.
In the production process, operators often step on the cell cover plate for convenience of operation (screwing an anode clamp, overhauling a device on the upper part of the cell and the like), and the cover plate is often subjected to mechanical deformation due to low mechanical strength. In addition, the deformed cover plates often have large gaps at the joints with each other due to mechanical strength, resulting in poor sealability. A large amount of ambient air enters the electrolytic cell through the gaps, so that the energy loss of the electrolytic cell and the processing load of the flue gas purification system are increased. In order to ensure a certain sealing effect in production, a mode of regularly replacing the cover plate is generally adopted (the service life of the cover plate is generally 2-3 years).
Compared with the cell cover plate added with heat insulation materials, the thin aluminum cell cover plate has the surface temperature difference of 30 ℃, which is not beneficial to the heat insulation of the electrolytic cell. On the other hand, long-term high-temperature heat radiation is easy to cause damage to operators.
Although a high-strength or insulation-added tank cover plate has also been developed, it is difficult for an operator to manually open and close the tank cover plate because the weight of the tank cover plate is significantly increased. If adopt hoisting apparatus to open and close, have the location difficulty and mention the back and take place the swing scheduling problem, have not been solved at present.
In order to be able to use a cover plate having high strength, high heat insulating property and high weight, there is a need for an improved cover plate system that can be opened and closed accurately and conveniently.

Detailed Description
To address the foregoing problems, the present disclosure provides an aluminum electrolysis cell hood system. The aluminum cell cover system adopts mechanical driving equipment, and can open and close the heavy cell cover plate; the sliding design is adopted, the groove cover does not need to be lifted and put down, and the accurate positioning of opening and closing is realized; and a rope winding mechanism is adopted, so that the space occupation is small. Because the mechanized moving of the tank cover plate is not carried by manpower any more, the tank cover plate can be designed into a tank cover plate with high strength, heat preservation function and large area. The mechanical movement of the cell cover plate can effectively reduce the labor intensity of operators, reduce the contact time of the operators and pollutants and reduce the damage of radiant heat in the electrolytic cell to the operators. The large mask plate with high strength is not easy to deform and has longer service life, and the sealing performance of the electrolytic cell can be better. The tank cover plate can be added with heat insulation materials, so that the heat loss of the electrolytic tank can be reduced, the energy consumption of electrolysis is reduced, and the energy conservation of aluminum electrolysis is realized.
Specifically, according to one embodiment of the present disclosure, there is provided an aluminum electrolysis cell enclosure system comprising:
a plurality of side cover plates, wherein the side cover plates are arranged in a side cover plate row along the length direction of the aluminum electrolytic cell, adjacent side cover plates are couplable, and the side cover plates are provided with rope fixing structures;
a sliding mechanism which enables the side cover plate to slide along the length direction of the aluminum electrolytic cell;
two cord winding devices, wherein the two cord winding devices are respectively positioned on the extension lines of the two ends of the side cover plate row, and a cord is fixed on each cord winding device, the cord can be wound on the cord winding device, one end of the cord is fixed on the cord winding device, and the other end of the cord can be connected to the cord fixing structure.
The disclosed aluminum electrolysis cell hood system includes a plurality of side hood panels. The side cover plates may be inclined to cover the electrolytic bath, similar to the aluminum bath cover plates in the related art. The plurality of side cover plates are independent of each other and arranged in a row of side cover plates along the length of the aluminum cell. The side cover plates are all positioned in the same plane. Adjacent side panels are couplable to each other. By couplable, what is meant herein is that adjacent side panels can be fixedly connected relative to each other so as to move together. Adjacent side shields can also be uncoupled and thus moved separately. The coupling can be effected by conventional coupling means. For example, this may be achieved by a latch.
Because this disclosure adopts mechanized open and close side cover plate, therefore compare with conventional fritter aluminium side cover plate, this disclosed side cover plate can be bigger. For example, the size of the side cover panel of the present disclosure may be twice, three times, or more larger than that of a conventional aluminum side cover panel, i.e., may correspond to the size of a plurality of conventional aluminum cover panels combined together.
The aluminum cell cover system also comprises a sliding mechanism. When one of the side cover plates slides along the slide mechanism, it will slide with all of the side cover plates in front of its sliding direction as it is in the side cover plate line. Therefore, when one side cover plate needs to be opened to operate in the aluminum electrolytic cell, the side cover plate only needs to be slid to the end part of the side cover plate line along the length direction of the aluminum electrolytic cell along the sliding mechanism. Similarly, when it is desired to close the side panel, the side panel is simply slid in the opposite direction back to the original position.
The aluminum reduction cell cover system also comprises a rope winding device and a rope, which are used for completing the sliding in a mechanized manner. The cord winding arrangement may be driven by any power means, such as electrical means.
The present disclosure employs a cord winding device and a cord to apply a force to a side panel to effect movement, i.e., opening and/or closing, of the side panel. The side cover panels have cord-securing structures, such as tabs, thereon.
In one embodiment, when it is desired to pull one of the side cover panels to the right, the cord on the right cord wrap is first secured to the cord securing structure of that side cover panel. Thereafter, the side panel is uncoupled from its left-side adjacent side panel and all of its right-side panels are coupled together. Subsequently, the right cord winding device is actuated so that the cord is wound up. The rope is then tightened and pulls the side cover plate to slide to the right, thereby opening the electrolytic cell.
Thereafter, when it is necessary to close the side cover panel, the cord on the right cord winding device is released from the cord fixing structure, and the cord on the left cord winding device is fixed to the cord fixing structure of the side cover panel. Subsequently, the left side cord winding device is actuated so that the cord is wound up. The rope is then tightened and pulls the side cover plate to slide to the left, thereby closing the electrolytic cell.
The present disclosure uses a rope winding device and a rope to pull the side cover panels. The inventor creatively adopts two rope winding devices at two sides, which are respectively responsible for the movement of the side cover plates to one side, and a rope fixing structure is arranged on each side cover plate, thereby flexibly applying driving force to any side cover plate which is expected to move.
In using the aluminum cell enclosure system of the present disclosure, manual securing of the cords to the cord securing structure is still required. However, the handling of the cord is much less difficult than handling and transporting the aluminum side panel. Also, the weight and size of the side cover panels can be greatly increased to obtain the benefits previously described.
The sliding mechanism may be any mechanism that allows the side cover plate to slide along the length of the aluminum electrolytic cell. For example, the sliding mechanism may include a roller, a rail, a slider, or a slider. For example, roller-rail or slider-slider engagement may be used.
In one embodiment, the sliding mechanism comprises a cover plate sliding member fixed to the side cover plate and a cell sliding member fixed to the aluminum electrolytic cell, the cover plate sliding member and the cell sliding member cooperating to effect the sliding. This way of achieving the sliding of the side cover plates is simple. Of course, other types of sliding mechanisms may be used. For example, a separate slide rail may be provided as a slide member, independent of the aluminum reduction cell, and fixed to, for example, the ground. For example, a slidable suspension ring may be provided on the rail and suspended from the top surface of the side panel. However, the arrangement of the electrolytic cell sliding component on the aluminum electrolytic cell saves space, and the matching and the positioning of the cover plate sliding component are more convenient and accurate.
The slide mechanism may comprise two or more sets of the cover plate slide member and the electrolytic bath slide member. For example, a set of cover plate slide members and cell slide members on the upper portion (e.g., top) of the side cover plate and a set of cover plate slide members and cell slide members on the lower portion (e.g., bottom) of the side cover plate. More than two sets of components may increase the stability of the system.
One problem encountered with sliding mechanisms is to allow access for anode replacement. One solution is to provide a removable slide mechanism. An easier way is that at the anode guide position of the aluminium electrolysis cell, the cell does not have cell sliding parts above the anodes. In other words, the cell slide can be interrupted at the anode stem position. This design allows access for anode replacement without affecting the sliding of the side cover plates. For example, the sliding mechanism may comprise at least one set of cover plate sliding members fixed to the side cover plates at the top of the electrolytic cell and cell sliding members fixed to the aluminum electrolytic cell, and the cell sliding members are discontinuous at the anode guide position of the aluminum electrolytic cell. The anode stem position referred to herein means a position corresponding to the anode stem in the longitudinal direction of the aluminum electrolytic cell. Generally, when the anode is replaced, the anode rod is horizontally moved to a position below the side cover plate, then lifted from the opened side cover plate, and then dropped after the anode is replaced, and then horizontally moved back to the original position. If the sliding part of the electrolytic bath is present at the position of the anode rod, the horizontal movement of the anode rod is hindered. Therefore, if a cell slide is provided at the top of the cell, it should be discontinuous at the anode rod position. The discontinuous design of the cell slide at this point does not affect the adequate opening of the side cover plates.
The cell slide may comprise a portion extending out of the aluminium electrolytic cell in the long direction of the aluminium electrolytic cell to provide better support for the portion of the side cover plate that protrudes out of the aluminium electrolytic cell when open. Further, a fixing panel for supporting the extension portion may be further provided.
In one embodiment, the aluminum reduction cell hood system has an end side hood plate stroke limiting device that limits the stroke of the end side hood plate. The travel limiting means may be, for example, a stop, a pin, etc. The end side mask plate stroke limiting means can prevent both excessive outward movement of the end side mask plate and excessive inward movement of the end side mask plate. For example, an outboard limit stop and an inboard limit stop may be provided. Thus, the stroke of the side cover plate to be opened and closed is limited.
In one embodiment, the side cover sheet is a heat-insulating cover sheet of a multi-layer structure. For example, it may have a three-layer structure consisting of a metal plate-insulating layer-metal plate. On one hand, the heat insulation effect is achieved, and on the other hand, better strength is provided.
The side cover plate may have a suitable structure such as a step for stepping.
The present disclosure also provides an aluminum electrolysis cell apparatus comprising the aluminum electrolysis cell cover system. It has the advantages of the cover system of the aluminum electrolytic cell, for example, better heat preservation performance can be realized.
The invention is further explained below with the aid of the drawing.
FIG. 1 is a schematic view of a cover plate of an aluminum electrolytic cell in the related art. In fig. 1, a denotes a side cover plate, B denotes an end fixing cover plate, and C denotes an end door. In the present disclosure, the disposition of the side cover plates may be similar to that of a in fig. 1.
Fig. 2 shows a schematic diagram of one embodiment of the present disclosure.
The notations in the figures have the following meanings: 1-rope winding mechanism, 2-rope, 3-limiting device, 4-side cover plate, 5-upper pulley/sliding block, 6-lower pulley/sliding block, 7-anode guide rod, 8-coupling device, 9-rope fixing structure, 10-fixing panel, 11-upper guide rail/sliding rod, 12-lower guide rail/sliding rod and 13-flange.
The guide rail/slide bar matched with the pulley/slide block is arranged on the electrolytic bath/fixed panel.
The upper sliding mechanism is discontinuous at the anode guide rod to leave a channel for the guide rod to move. The lower slide mechanism may be continuous.
For ease of illustration, three side panels are schematically shown in simplified form. It will be appreciated that the side cover plates may be more pieces in an actual electrolytic cell.
When it is desired to open the cell, for example at the right anode guide bar 7, the coupling device 8 at that location is uncoupled and the ropes 2 on both sides are respectively fixed to the rope fixing structures 9 on the side cover plates. Subsequently, the rope winding devices 1 on both sides are respectively activated, thereby opening the side cover panels. In the process, the space occupied by the whole system is unchanged. When it is desired to close, the rope on the left rope winding device is connected to the rope fixing device of the opened right side cover panel, and the rope on the right rope winding device is connected to the rope fixing device of the opened left side cover panel, the rope winding device 1 is activated, thereby closing the side cover panels. Two stop means 3 at the left end of the figure may limit the travel of the left end side mask plate 4. For example, a flange 13 may be provided on the edge of the left end side panel 4, and movement to the left to some extent may be stopped by the left side stopper and movement to the right to some extent may be stopped by the right side stopper.
The rope fixing means may be of various designs. For example, as shown in fig. 3, one side panel 4 may have four cord securing structures 91-94. 91. 92 is used for fixing the left side rope, and 93, 94 are used for fixing the right side rope to can make left and right sides rope fixed simultaneously, avoid having to dismantle one side rope earlier just can fix the opposite side rope, thereby improve work efficiency.
Turning to fig. 2, a slide mechanism is shown. The upper sliding mechanism consists of an upper pulley/slide block 5 and an upper guide rail/slide bar 11, and the lower sliding mechanism consists of a lower pulley/slide block 6 and a lower guide rail/slide bar 12. Of course, the aluminum cell cover system of the present disclosure may have more sets of sliding mechanisms. The side cover plate 4 can slide along the slide mechanism.
As shown, the upper rail/slide 11 is discontinuous at the anode stem 7. Thus, when the side cover plates are pulled apart, the anode rods can be moved horizontally (in the direction out of the page in fig. 3) below the surface of the cell plate and then lifted to remove the anodes, and can be lowered and moved horizontally (in the direction in the page) back into place after replacement of the anodes. The upper pulley/slide 5 is shown as discontinuous. However, it may also be continuous and dangling at a discontinuity of the upper rail/slide 11. Because the side cover plates can be removed, the continuously arranged upper pulleys/sliders 5 do not hinder the horizontal movement of the anode rod.
Fig. 4 schematically shows an embodiment in which the upper rail 11 is discontinuous but the upper pulley 5 is continuous. As shown, the movement of the side cover plate 4 to the right, although the upper rail 11 is discontinuous, does not affect the exposure of the anode.
In one embodiment, the sliding mechanism of the present disclosure comprises at least one set of cover plate sliding members fixed to the side cover plates and cell sliding members fixed to the aluminum electrolytic cell, the cover plate sliding members and the cell sliding members cooperating to achieve the sliding,
wherein the cover plate sliding member includes:
the lower sliding block is lower than the lowest height of the anode steel claw; and
a bottom roller lower than the lower slider;
the fixed slide member includes:
a slide bar matched with the lower slide block; and
a guide rail cooperating with the bottom roller, the guide rail being suspended;
the sliding mechanism further comprises a bottom roller protection cover, and the bottom roller is connected to the side groove cover through a supporting portion passing through a gap below the bottom roller protection cover.
The problem of residue and dust accumulation can be solved by matching the bottom roller protective cover with the suspended guide rail.
Fig. 5 illustrates a chute cover plate lower slide mechanism according to one embodiment of the present disclosure.
The notations in the figures have the following meanings: 1-side cover plate, 21-bottom roller, 22-guide rail, 23-bottom roller protective cover, 24-supporting part, 26-detachable connecting device, 31-lower sliding block, 32-sliding rod and 36-detachable connecting device.
As shown, the side cover plate 1 is connected to the bottom roller 21 and the lower slider 31 by detachable connection means 26, 36, respectively. Wherein the connection to the bottom roller 21 is via a support 24 which passes through the gap under the bottom roller shield 23, i.e. the gap between the guide rails 22. The left half of the guide rail 22 is suspended. The space below it is used to accumulate debris or dust and to allow the support 24 to pass.
In one embodiment, the cover plate sliding member further comprises:
a top roller;
the fixed slide member includes:
a guide rail cooperating with the top roller.
With the above configuration, the sliding mechanism of the present disclosure can effectively avoid the influence of dust accumulation on the sliding and sliding members. The sliding rod sliding block system and the roller guide rail system exist simultaneously, and the bearing capacity and the sliding capacity can be achieved simultaneously.
The detachable attachment means 26, 36 in the figures are schematic and may in particular be magnets or latches or the like for individual detachment of the side panel 1.
Preferably, as shown, the protective cover 23 and the guide rail 22 are integrally formed.
While the bottom slide member may already provide sufficient sliding, the present disclosure may also include the top slide member described above to increase stability. The top roller may also have problems with dust. Thus, in one embodiment, a top roller shield may be provided.
In one embodiment, the cage slide further comprises a top ball. The top ball can assist sliding and can play a certain sealing role.
In one embodiment, the cover plate slide member is detachable from the side cover plate. Thus, the side cover plate can be replaced without removing the cover plate sliding member.
Figure 6 illustrates a bezel plate top slide mechanism according to one embodiment of the present disclosure. It comprises a top roller 41, a guide rail 42. It may also include a top roller shield 43 for sealing against escape of gas from the chamber. It may also include balls 44 to improve sealing and to some extent to improve the smoothness of the sliding.

In order to reduce the labor intensity of operators and improve the sealing and heat-insulating performance of the electrolytic cell, the scheme is implemented on the 350KA double-anode aluminum electrolytic cell. The upper edge and the lower edge of the side cover plate of the electrolytic bath are provided with sliding guide rails, wherein the upper rail is an interrupted rail due to the existence of the anode guide rod, and the lower rail is a continuous rail; the method is characterized in that a cell cover plate is manufactured into a large-size mask plate, the area of the large-size mask plate is twice that of the original cell cover plate, the size of the large-size mask plate is 1600mm 1370mm, the cell cover plate is designed into a double-layer heat insulation structure in the scheme, and two pull rings are fixedly arranged on two sides of each cell cover plate; the size of the fixed panel is designed to be 1600mm 1050mm, and the size of the fixed panel can be adjusted in length according to the groove type and the field space condition.
When the anode at a certain position is replaced, an operator loosens the locking device on the tank cover plate, fixes the pull ropes at two sides on the pull rings of the tank cover plates at two sides of the anode guide rod respectively, starts the power motors at two sides of the electrolytic tank, straightens the pull ropes through the scroll and pulls the pull ropes to two sides, and the motor is automatically closed when the tank cover plate at the end part reaches the outer side limiting device; after the pole changing is finished, the operating personnel change the positions of the inhaul cables on the two sides, start the power motors on the two sides of the electrolytic cell, pull the inhaul cables straight and towards the middle through the scroll, automatically close the motor when the end tank cover plate reaches the inner side limiting device, lock the locking device on the tank cover plate by the operating personnel, and finish the whole pole changing work.
By implementing the scheme, the labor intensity of operators is effectively reduced, and the contact time of the operators and pollutants is reduced; because the tank cover plate in the scheme has higher strength, the deformation is small in the operation process, and the tank cover plate is locked by the locking device in the electrolysis process, the gas collection efficiency of the electrolysis tank reaches more than 98.5 percent from the original 96.3 percent after the operation is stable, the tightness of the tank chamber is greatly improved, the unorganized emission of smoke is reduced, and the operation pressure of a subsequent purification system is reduced; and the tank cover plate in the scheme is added with the heat insulation material, so that the heat loss of the upper part of the tank is reduced, the electrolysis energy consumption can be reduced to a great extent, and the energy saving of aluminum electrolysis is realized.
It will be apparent to those skilled in the art that various changes and modifications may be made in the embodiments of the disclosure without departing from the spirit and scope of the disclosure. Thus, if such modifications and variations of the present disclosure fall within the scope of the claims of the present disclosure and their equivalents, the present disclosure is intended to include such modifications and variations as well.
