Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method and an apparatus for continuous treatment of aluminum dross, in which a flow component such as molten aluminum metal or air mixed in dross contained in aluminum dross generated and scraped sequentially in a processing furnace is removed. High quality aluminum with high aluminum content by appropriately compressing and separating the arch formed in the dross while squeezing and separating to increase the aluminum recovery rate from the dross and appropriately restricting the oxidative consumption of aluminum by air mixed in the dross Provided is a method and apparatus capable of obtaining a dross and effectively performing a stable, accurate, and efficient treatment even under operating conditions in which a large amount of aluminum dross is continuously generated. Another object of the present invention is to provide a method for producing additives such as deacidification and desulfurization.
[0002]
[Prior art]
It is well known that aluminum dross is generated during dissolution of aluminum, and such aluminum dross contains a considerable amount of metallic aluminum. Therefore, the separation and recovery of such metallic aluminum has been studied and implemented in the past, and as a general method, it is contained in aluminum dross scraped from a processing furnace such as a melting furnace. In order to increase the recovery rate of aluminum in the dross, it is possible to squeeze and separate the flow components, such as molten aluminum metal and air mixed in the dross, while appropriately destroying the arch formed in the dross during the squeeze discharge. Another object of the present invention is to reduce the oxidation of aluminum by air mixed in the dross to obtain a high-quality aluminum dross cake having a high aluminum content.
[0003]
That is, as a method for collecting metal aluminum as described above, dross in a high-temperature state scraped out of the processing furnace is put into a container, and the oxide film surrounding the metal aluminum is weakened by adding a flux for raising the temperature, removing slag, etc., and stirring. And a method in which metal droplets are collected and separated from oxides by gravity, or a method in which a liquid aluminum is squeezed out by placing it in a container having an opening at the bottom and applying pressure. In addition, in these processes, a method of applying vibration together with pressure to make squeezing more efficient has been proposed.
[0004]
In addition, the present inventors have repeated various studies on the adoption of a squeezing method for the separation and recovery of metal aluminum in dross as described above, and have made an effective proposal, that is, squeezing dross to reduce the amount of aluminum metal. The aluminum content in the dross after treatment is increased by increasing the rate of separation and recovery of metallic aluminum by removing the air in the dross and limiting the oxidation of residual aluminum by separating the aluminum. It has been successfully used.
[0005]
[Problems to be solved by the invention]
Although the conventional separation and recovery of metal aluminum in dross by gravity as described above increases the recovery rate of aluminum, the addition of a flux for raising the temperature and removing slag reduces the aluminum by burning the bent aluminum. In addition, a large amount of gas and dust is generated during the processing operation, which not only deteriorates the working environment but also pollutes the surrounding environment, and in some cases, causes environmental destruction due to an explosion. Furthermore, the method of adding vibration can destroy the arch to some extent, but produces unbearable noise and vibration, and measures to prevent them are considerably expensive, and the installation place of the device is also restricted. Will be done.
[0006]
On the other hand, aluminum melting equipment has recently become quite large, and the amount of dross generated on the surface of molten aluminum has also become quite large, making it very difficult to efficiently treat such a large amount of aluminum dross. . Moreover, in such an aluminum dross, oxidative consumption of aluminum in the dross progresses due to the high temperature conditions in the state of being taken out of the melting furnace and the high temperature conditions due to the addition of the flux and the like, and the utility value of the dross decreases. In addition, the arch is formed due to the frictional resistance of the dross solid and the squeezing is hindered, leaving a void in the dross after the squeezing. It is unavoidable that the residual metal in the mold and the oxygen in the voids react with each other to cause metal consumption due to oxidation. Furthermore, it is necessary to limit the amount of processing at one time in order to limit the crushing inhibition by the arch as much as possible, and it is difficult to obtain a favorable result. In addition, a product which is preferable as a heat insulating agent or an additive for deoxidation, desulfurization and the like in a steelmaking operation is required.

[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
A specific embodiment of the present invention as described above will be described with reference to the accompanying drawings as appropriate. In the present invention, as shown in each part in FIG. A plurality of dross containers 10 in which the body 2 and the dross receiving frame 3 are appropriately disassembled and these can be loaded and assembled are employed, and a push plate 5 is used together with such a container 10. However, the dross container 10 as described above is housed in the container 10 set in the setting operation A as shown in FIG. 1, for example, after loading the dross B, pressing plate insertion operation C, pressing operation D, cleaning and cooling operation. F, a cake dispensing operation H, a pressing plate collecting operation I, and a dross receiving frame placing operation L are performed through a pressed dross demolding operation G, and a standby operation is performed at a container standby J. At this position, a metal return operation E is performed. The metal receiving unit 1, slit unit 2, and empty dross receiving frame 3 return to the setting operation A in preparation for the next operation, and the same processing steps are sequentially performed.
[0018]
That is, in the setting operation A, the slit portion 2 and the dross receiving frame 3 are mounted on the metal receiving portion 1 as a dross container 10 in a stacked state, and such a dross container 10 is mounted in the dross receiving frame 3 on the slit portion 2. The dross 4 scraped from the furnace is accommodated in the dross processing apparatus, and the dross is carried into the dross processing apparatus. Then, the dross 4 is transferred to the pressing plate inserting operation C, and the pressing plate 5 is inserted on the dross 4 described above.
[0019]
Next, the dross pressing operation D is performed on the dross 4 housed as described above, that is, a pressing force is applied from above through the pressing plate 5 to compress the bulky dross 4 and contain the dross 4 in the dross. The metal component and the air component are squeezed through the slit body 2, and the metal component is received by the metal receiving portion 1. The bulky dross 4 becomes a compressed dross 9 whose apparent volume is reduced by the pressing operation D. The metal receiving portion 1 receiving the squeezed metal 6 and the dross receiving frame 3 containing the compressed dross 9 whose volume has been reduced by pressing are moved together with the slit portion 2 to the next cleaning and cooling operation F and cooled. Then, the dross receiving frame 3 is released from the compressed dross 9 to the next compressed dross demolding operation G. Next, the operation proceeds to the dispensing operation H, in which the dross cake 8 and the pressing plate 5 on the slit portion 2 are discharged from the slit portion 2, and the slit portion 2 is removed together with the metal receiving portion 1 containing the metal 6 by the above-described compressed dross removal. It is returned to the position of the mold work G, and the dross receiving frame 3 previously separated at this position is assembled (L) to be in the standby state J.
[0020]
At the position of the standby state J described above (or the position of the setting operation A such as in front of the furnace), the metal receiving portion 1 is removed from the slit body 2, and the solidified metal 7 solidified in the metal receiving portion 1 is received. The metal receiving unit 1 is taken out of the processing furnace, returned to the processing furnace, and reused, and the metal receiving unit 1 moves to the above-described set operation A at the above-described standby state position or a position such as in front of the furnace, and is prepared for the next dross storage. .
[0021]
FIG. 2 shows an example layout of a preferred processing facility for continuously and circulating the processing operation as shown in FIG. 1 described above. FIG. 2 shows the locus of movement of each member at the same time. Here, the dotted line (...) 30 is the metal receiving part 1, the dashed line (──, ─, ──) 31 is the dross receiving frame 3, and the two-dot chain line (──, ──, ・) ) 32 denotes the slit body 2, solid line (───) 33 denotes the dross 4, and broken line (────) 34 denotes the movement locus of the push plate 5. In other words, the steps can be considered stepwise, such as the dross loading operation B and the push plate insertion operation C, but the equipments such as the dross container B need to be fluctuated especially for the operations B and C. There is no need to carry out these operations while the loading of the dross container 10 is stopped at a certain start position a. From this position, the dross container 10 is moved to the pressing operation position d by the transfer rail 11, and the dross in the container 10 is compressed. Added.
[0022]
In the pressing operation position d, pressing the dross 4 inserted into the dross receiving frame 3 on the slit portion 2 in the dross container 10 as shown in FIG. It is known that the operation is performed by a pressing cylinder, and the specific equipment and operation are as disclosed in Japanese Patent Application Laid-Open No. 9-111357 proposed by the present inventors. That is, the dross 4 in the receiving frame 3 is pressed through the pressing plate 5, and the molten aluminum metal contained in the dross 4 is dropped and stored in the metal receiving portion 1.
[0023]
When the processing at the pressing position d as described above is completed, the slit body 2 is separated from the metal receiving section 1 by a locking tool 15 as shown in FIG. It is. That is, a part of the metal squeezed from the slit body 2 is solidified, and the bamboo-shaped protrusion 23 connecting the slit body 2 and the metal 6 is cut. 23 is prevented from being caught and hindering the work.
[0024]
Next, the processed product is sent to the cleaning / cooling position k, in which the cooling fans 12 are arranged in multiple stages. In particular, the first stage fan 12 has a bag filter mechanism 13. By providing the suction / exhaust system 14, the air is purified and then discharged to the outside. The next second and third stage fans 12 cool the compressed dross 9 continuously. Here, the metal receiving section 1 may be removed from the dross container 10 in the following manner before being transferred to the cleaning / cooling position k, and the process in this case is shown in FIGS.
[0025]
That is, after the pressing operation d, before being transferred to the cleaning and cooling position k, it was moved to the metal receiving portion separating position e and attached to the bottom of the slit portion body 2 as shown in the metal returning operation E in FIG. When the metal receiving portion 1 is separated, the aluminum metal contained in the metal receiving portion 1 is at least substantially partially melted at the time of such separation, and is cooled and hardened after separation to solidify the metal 7. As shown in the lower part of the metal returning operation section E, the metal 7 thus separated is returned to the furnace and reused. However, the compressed dross 9 in the dross container 10 from which the metal receiving unit 1 is separated is at a high temperature, and in some cases, the remaining metal in a molten state is dripped from the slit body 2 portion after the next step, thus contaminating the equipment. In such a case, it may not be preferable to separate the metal receiving unit 1 from the container 10. In such a case, the processing is performed with the metal receiving unit 1 attached to the standby position j as shown in FIG. Is more preferred. Other movements are the same as in FIG. 1 and FIG.
[0026]
1 and 2 will be described in more detail. As described above, the compressed dross 9 after being cooled, the dross receiving frame 3 is released from the compressed dross releasing position f as shown in FIG. Then, the slit body 2 is transferred to the cake dispensing operation H and is paid out, and is discharged from the slit body 2 with the push plate 5 attached to the dross cake 8. Next, the pressing plate 5 on the dross cake 8 is also removed as shown in FIG. 1I, and the metal receiving portion 1 that has received the remaining slit body 2 and the metal 7 is in the compressed dross demolding position f in FIG. That is, the dross receiving frame 3 is returned to the dross receiving frame mounting position l, and the dross receiving frame 3 waiting at the position 1 is mounted on the slit body 2, and is moved to the container standby position j formed so as to protrude out of the circulation line. Accepted as needed and wait. Next, at the standby position j or at a position such as in front of the furnace, the metal 7 is taken out of the metal receiving section 1 and returned to the furnace, and the metal receiving section 1, the slit body 2 and the dross receiving frame 3 are set again. It is temporarily placed in such a standby position j or in front of a furnace, dross is charged in front of the furnace, moved to the start position a, and subjected to the above-described processing repeatedly.
[0027]
A push plate collecting position h and a push plate stock position i are appropriately formed between the dross cake payout position g and the start position a as shown in FIG. 2, and the dross cake is taken out below the push plate collecting position h. The dross cake obtained sequentially is provided by providing a portion, and the push plates deposited at the push plate stock position i are appropriately loaded on the loading dross at the start position a.
[0028]
In order to accurately carry out the dross cake removal as described above, the present inventors have replaced the conventional holding tool 18 having only the locking projection 17 as shown in FIG. It is proposed to use a holding device 18a that uses the portion 16 and the locking projection 17 together. That is, by using the cake receiving portion 16 and the locking projection 17 in this way, it is possible to appropriately prevent the dross cake which often occurs in the conventional one shown in FIG. Damage due to cake falling can be properly avoided.
[0029]
As a method of loading and unloading the push plate 5 on the dross 4 accommodated in the dross receiving frame 3, the present inventors form a holding projection 19 at the center of the push plate 5 as shown in FIG. At the same time, it is proposed to provide a cap-shaped protrusion 21 having an inclined surface 20 circumscribed on the top peripheral side of the holding protrusion 19, and such a cap-shaped protrusion 21 is used for holding the push plate 5. Even when the axis is slightly displaced when the head 22 is lowered, the gripping head 22 is appropriately guided by the inclined surface 20 of the cap-shaped projection 21 to perform proper centering, and the effective mounting and dismounting of the push plate 5 is performed. Make
[0030]
To further explain the bamboo-like projection 23 as shown in FIG. 5, the present inventors have determined that the metal extruded depending on the nature of the dross to be treated in continuously treating the aluminum dross as described above. As shown in FIG. 5, the solidification protrudes in the form of bamboo shoots in the metal receiving portion 1, and when the operation is performed with such a bamboo-like protrusion portion 23 formed, the slit body 2 and the dross cake at the upper portion thereof are fixed. In other words, if the operation is performed while the bamboo-like projections 23 are generated, it is difficult to assemble or operate the dross container unit and to cause a recovery metal overflow.
[0031]
Moreover, the work of removing the bamboo-shaped protrusions 23 generated as described above is extremely difficult, and it is necessary for an operator to go under the slit body 2 to perform the work of removal. In this case, the slit body 2 is removed by heating with a burner or the like, but in any case, the number of steps is large, the risk is large, and the slit body 2 and the forklift are disadvantageously damaged. .
[0032]
In order to avoid such disadvantages due to the formation of the bamboo-like projections 23, the present inventors engaged the slit body 2 in a state where the metal does not solidify immediately after the metal of the dross is squeezed or even when the metal is solidified. It is raised by the stopper 15 to cut off the fixation by the bamboo-like projection 23, and is assembled after the solidification of the projection 23 to proceed to the next step, thereby effectively preventing the disadvantage or accident as described above, and the slit body 2 is fixed. It is possible to operate smoothly and to operate safely without doing anything.
[0033]
According to the present invention as described above, a plurality of dross containers and a push plate provided detachably with a slit body and a dross receiving frame with respect to a metal receiving portion are used, and the dross container is moved from the container assembly temporary storage position. After loading the dross in front of the furnace, transfer to the dross loading position, push plate insertion position, pressing position, cleaning / cooling position and pressing dross demolding position, dross cake payout position, and dross receiving frame mounting position, and set them at each position. By operating the operation device and performing each operation, molten aluminum metal or air mixed in dross contained in the aluminum dross generated and scraped sequentially in the processing furnace is formed in the dross. Separates accurately under conditions where arches and the like are effectively destroyed, increasing the aluminum recovery rate from dross and entraining air According properly tighten obtain high quality aluminum dross limit the oxidation of aluminum, yet effectively allowed to implement stable and accurate and efficient processing in mass of operating conditions of aluminum dross occurs continuously reasonably.
[0034]
Further, according to the present invention, after the squeezing process at the squeezing position or after placing the dross receiving frame, the metal receiving portion is separated and the metal is returned to the furnace, and the metal receiving portion is returned to the container assembling position. By setting the dross receiving frame on the metal receiving portion and the slit seat obtained from the above and receiving the aluminum dross, the dross container can be effectively circulated for efficient continuous processing of the aluminum dross.
[0035]
Further, according to the present invention, the pressing plate is taken out together with the dross cake, the dross cake obtained by separating and collecting the pressing plate is integrated, and the pressing plate is inserted into the dross accommodated in the dross receiving frame and pressed. Thereby, efficient pressing using the pressing plate can be smoothly performed in the dross receiving frame.
[0036]
Further, in the present invention, after the aluminum dross received in the dross container is squeezed at the squeezing position, the aluminum does not solidify or is separated from the slit body during a considerably high temperature, and after the solidification is terminated in the separated state, Smooth dross processing that makes effective use of the slit body by sending it to the metal removal position is performed.
[0037]
The dross container provided with a detachable slit portion for separating molten metal in the dross with respect to the metal receiving portion can be squeezed from the dross receiving position to the pressing position, the cleaning / cooling position, the pressing dross demolding position, the dross position. A cake delivery position, a transfer system for sequentially transferring to the dross receiving frame placement position is provided, and the dross processing of the present invention as described above is provided by arranging operating devices for performing the respective operations at the respective positions. It will be implemented smoothly by efficient use of equipment.
[0038]
Further, in the present invention, by providing a push plate insertion position for inserting the push plate on the aluminum dross received between the dross loading position and the pressing position, the aluminum dross in the entire container in which the push plate is inserted can be effectively used. An apparatus is provided that can be implemented.
[0039]
Further, in the present invention, an air vent provided with a bag filter is appropriately disposed between the cleaning and cooling position and the dross cake take-out position from the cleaning and cooling position to clean the dross container and cool the dross cake. Thus, a series of dross treatments can be smoothly performed under relatively clean atmosphere conditions.
