TECHNICAL FIELD OF THE INVENTION
The present invention relates to a high-temperature object storage facility (hereinafter, simply referred to as a storage facility) for storing a high-temperature object such as a hezlet anode generated in a copper smelting process.
[0002]
[Prior art]
In the copper smelting process, high-purity copper material is obtained by forming molten copper refined by smelting copper concentrate into a substantially rectangular flat plate called an anode and electrolytically refining it. I'm trying to get.
Here, as this kind of anode, a molten copper is generally cast into a casting mold and formed into a flat plate, but in addition to this, a long flat plate called a so-called hezlet anode is used. It is also known that copper is cut out of copper in a high temperature state formed into a shape by a press or the like and formed into a substantially rectangular shape. However, the anode formed by casting is quenched by water cooling or the like and then subjected to electrolytic purification.However, the above-mentioned hezlet anode is warped when quenched due to its thin thickness compared to the anode formed by casting. Because of the danger, it is stored outdoors or the like while being cut out by a press or the like, gradually cooled, and then subjected to electrolytic refining.
Conventionally, storage of such a hezlet anode has merely been carried out by directly placing the hezlet anode on a concrete floor provided outdoors.
[0003]
[Problems to be solved by the invention]
However, since the surface temperature of the hezlet anode immediately after being cut out by a press or the like remains at a high temperature of about 600 ° C., if it is directly placed on a concrete floor, the floor is damaged by heat. The cracks and peeling occurred on the floor in a short period of time, resulting in unevenness, and the anode could not be stably mounted. Therefore, there was a problem that the floor had to be repaired frequently. On the other hand, to protect the floor, for example, even if a pedestal having heat resistance is installed on the floor and a hezlet anode is placed on it, the pedestal is thermally deformed by the heat of the hezlet anode. There was an inconvenience of distortion.
In addition, powdery copper oxide is formed on the surface of the hezlet anode while it is being stored, and the copper oxide powder peels off from the surface and falls onto the floor. This copper oxide powder is preferably reused as a material of the formed product in terms of cost, but if the floor is damaged by heat, the copper oxide powder enters into the unevenness of the damaged floor, so it is recovered. Had become difficult.
[0004]
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a storage facility capable of reducing floor damage caused by a high-temperature object such as the above-mentioned hezlet anode.
[0005]
[Means for Solving the Problems]
The storage facility according to the present invention has heat resistance, a pedestal on which a high-temperature object is placed is installed on the floor, and the pedestal has a configuration in which a plurality of units having heat resistance are arranged adjacent to each other. Each unit is characterized in that only the central part is fixed to the floor and the other parts are not fixed .
In the storage facility configured as described above, since the high-temperature object is not placed directly on the floor, but is placed on a pedestal having heat resistance, damage to the floor due to heat can be reduced. And since this pedestal has a configuration in which a plurality of units having heat resistance are arranged adjacently, even if thermal expansion occurs in each unit, distortion does not propagate between the units and the distortion is not amplified, The distortion generated in the entire pedestal can be reduced.
[0006]
In each of these units, only the central part is fixed to the floor, and the other parts are unfixed, so that while the unit is fixed to the floor, distortion generated in the unit is released to the non-fixed end and distortion occurs. Can be reduced.
Each of these units is provided with an engagement portion that is fixedly engaged with another adjacent unit and suppresses a shift in the orientation of the end portions while allowing mutual thermal expansion. Even if distortion due to thermal expansion occurs, it is possible to allow the thermal expansion of each other and release the distortion, while suppressing the deviation in the direction between the ends of the adjacent units by the engagement portion.
[0007]
Here, when the high-temperature object is stored outdoors like the above-mentioned hezlet anode, the oxide powder dropped from the high-temperature object (copper oxide powder when the high-temperature object is a hezlet anode) is easily blown off by the wind. Was. In addition, since a forklift is mainly used to transport a high-temperature object, the oxide powder is rolled up by a forklift wheel and scattered around when a high-temperature object is transported. As described above, it was difficult to recover the oxide powder dropped from the high-temperature object, and the recovery rate was low.
Therefore, by using a rail as a unit of the pedestal and further configuring a plurality of sets of rails arranged adjacently along the longitudinal direction so as to be substantially parallel, a plurality of sets of rails are arranged between the sets of rails arranged in parallel. Oxide powder is deposited on the surface. Since the wind is blocked by the rail, the oxide powder deposited between the pair of rails is less likely to be blown off by the wind.
In addition, a set of rails arranged substantially parallel to each other is moved so that a forklift for transporting a high-temperature object can move along the longitudinal direction of the rails while straddling all the sets of rails arranged substantially parallel to each other. If the forklift is placed within a narrower width than the distance between the left and right wheels of the forklift, hot wheels can be loaded and unloaded without entering the forklift between pairs of rails on which oxide powder is deposited. Scattering of the oxide powder at the time of transport can be reduced.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view illustrating a schematic configuration of a storage facility according to an embodiment of the present invention, FIG. 2 is a side view illustrating a configuration of a main part of a pedestal of the storage facility according to the embodiment, and FIG. It is a sectional side view showing a schematic structure of such storage equipment.
A storage facility 1 according to an embodiment of the present invention stores a high-temperature object outdoors, and as shown in FIG. 1, has a heat-resistant property in which the high-temperature object is placed on a floor F made of concrete, for example. Is provided. Here, in this embodiment, a hezlet anode H cut out from a copper plate by pressing (hot working) is used as the high-temperature object. At the upper end of the hezlet anode H, an ear E serving as a hanging part when electrolytically refining the hezlet anode H is formed so as to protrude to the side, and the ear E can be held and transported by a forklift. It has become. Further, the hezlet anode H is formed by continuously cutting a long plate material into a plurality of plate materials having substantially the same shape with the upper and lower portions being alternately formed by press working. A notch C having the same shape as the ear E of the hezlet anode H, which is alternately cut up and down, is formed.
[0009]
The pedestal 2 has a plurality of heat-resistant rails 3 (units). In the present embodiment, the rail 3 is made of metal, particularly a 15 kg rail (railroad rail) made of carbon steel, and its length is 1 m.
The pedestal 2 includes two sets of such rails 3 in which a plurality of such rails 3 are arranged adjacent to each other in the longitudinal direction thereof, substantially parallel to each other. A heat-resistant stand 4 against which the anode H can rest is provided. Here, the distance between the left and right wheels of the forklift is set such that the two sets of the rails 3 can move along the longitudinal direction of the rails 3 with the forklift straddling the sets of the rails 3. It is arranged within the narrow width D1. The width D2 between the pair of rails is slightly wider than the space between the notches C of the hezlet anode H.
[0010]
Each of these rails 3 is fixed to the floor F only at the central portion by the fixture 6, and the other portions are not fixed.
At least one end of each of the rails 3 is provided with an engaging portion 7 that is fixedly engaged with the adjacent other rail 3 to suppress mutual deviation while allowing mutual thermal expansion. Is provided.
In the present embodiment, as shown in FIG. 2, a plate in which one end of each engaging portion 7 is protruded toward the front end of the rail 3 and the other end is fixed to a side surface of the end of the rail 3 by welding or the like. The adjacent rails 3 are arranged such that one end of the other rail 3 is sandwiched between the plate-like members 8 provided at the end of one of the rails 3. Have been. Here, the rail 3 has an I-shaped or inverted T-shaped cross section having a constriction on the side surface, and the plate-like members 8, 8 sandwich the constricted portion B of the other rail 3 to form one of the rails 3. The movement of the end of the other rail 3 with respect to the end in the vertical and horizontal directions is suppressed.
[0011]
In the storage facility 1 configured as described above, the hezlet anode H is conveyed with the ear E held by a fork of a forklift, and is placed on the pedestal 2 so as to straddle a set of two rails 3 constituting the pedestal 2. Is placed. At this time, the hezlet anode H is supported by the rails 3 at portions where the notches C on both sides at the lower end are formed. Here, the hezlet anode H is positioned at a lateral position (a position in the width direction of the rail 3) by being guided along the edge of the notch C by the rail 3, and is aligned on the pedestal 2. It is placed and carried in and carried out by a forklift smoothly.
Since the hezlet anode H is supported at both ends near the rail 3, most of the oxide powder P (copper oxide powder) dropped from the surface of the hezlet anode H falls between the pair of rails 3. It will be.
Further, the forklift moves along the longitudinal direction of the rail 3 in a state where the left and right wheels are located outside the set of the rails 3 across the set of the rails 3 arranged substantially in parallel. The loading and unloading of the let anode H are performed.
[0012]
According to the storage facility 1 configured as described above, since the hezlet anode H is placed on the pedestal 2 having heat resistance, damage to the floor F due to heat of the hezlet anode H can be reduced. . Since the pedestal 2 has a configuration in which a plurality of rails 3 having heat resistance are arranged adjacent to each other, even if thermal expansion occurs in each of the rails 3, distortion does not propagate between the adjacent rails 3, The distortion generated in the entire pedestal 2 can be reduced, and the hezlet anode H can be held well.
[0013]
Each of the rails 3 is fixed to the floor F only at the central portion, and is not fixed at the other portions. Therefore, while the rail 3 is fixed to the floor F, distortion generated in the rail 3 is fixed to the floor F. Escape to the end can reduce distortion.
Since the rails 3 are provided with the engaging portions 7 which are fixedly engaged with the other adjacent rails 3, even if the respective rails 3 are distorted due to thermal expansion, mutual distortion is generated. It is possible to hold the hezlet anode H satisfactorily while preventing the end portions of the adjacent rails 3 from being misaligned by the engaging portion 7 while the escape is performed.
[0014]
Also, most of the oxide powder P dropped from the hezlet anode H falls between the pair of rails 3 and accumulates. Since the wind is blocked by the rail 3, the oxide powder P deposited between the pair of rails 3 is less likely to be blown off by the wind. Further, since damage to the floor F is reduced and unevenness of the floor is reduced, the oxide powder P can be easily collected.
Further, since the forklift moves along the longitudinal direction of the rails 3 while straddling these sets of rails 3, the wheel of the forklift does not enter between the sets of the rails 3 where most of the oxide powder P is deposited. The hezlet anode H can be carried in and out of the pedestal 2, and the scattering of the oxide powder P during the transportation of the hezlet anode H can be reduced. Then, if the oxide powder P deposited between the sets of the rails 3 is discharged along the longitudinal direction of the rails 3, it can be easily collected.
As described above, according to the storage facility 1 of the present invention, the oxide powder P is less likely to be scattered around, and the recovery rate can be improved.
[0015]
Here, in the above-described embodiment, an example in which the copper-made hezlet anode H is used as the high-temperature object has been described. However, without being limited to this, the storage facility 1 according to the present invention may have any material and shape. Hot objects can be stored. In this case, the material, shape and arrangement of the units constituting the pedestal 2 are changed according to the material, shape and temperature of the high-temperature object so that the handling of the high-temperature object is good.
Further, in the above-described embodiment, an example in which the rail 3 is used as a unit constituting the pedestal 2 is shown. However, the present invention is not limited to this. For example, a plurality of heat-resistant plate members or blocks are arranged adjacently on the floor F. By doing so, the pedestal 2 may be configured.
[0016]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to the storage facility concerning this invention, since a high-temperature object is mounted on the pedestal which has heat resistance, the damage of the floor by heat can be reduced, and this pedestal has the structure which arrange | positioned several units adjacently. In addition, since distortion due to thermal expansion generated in each unit does not propagate between the units, distortion generated in the entire pedestal can be reduced and a high-temperature object can be held favorably.
Further, since damage to the floor is reduced and unevenness of the floor is reduced, it is easy to collect the oxide powder.
[0017]
And, in each of these units, only the central part is fixed to the floor and the other parts are unfixed, so that while fixing the unit to the floor, the distortion generated in the unit is applied to the non-fixed end. It can escape and reduce distortion.
Further , by providing these units with engaging portions that are engaged with other adjacent units in a non-fixed manner, the displacement of the ends of the adjacent units can be prevented while releasing the distortion due to the thermal expansion of each unit. Can be suppressed, and the high-temperature object can be favorably held.
[0018]
In addition, by using a rail as a unit of the pedestal and further arranging a plurality of sets of rails arranged adjacently along the longitudinal direction so as to be substantially parallel to each other, oxide powder can be interposed between these sets of rails. Is accumulated and the wind is blocked by the rail, so that the oxide powder deposited between the pair of rails is less likely to be blown off by the wind.
Furthermore, if the set of these rails is arranged within a width smaller than the distance between the left and right wheels of the forklift, the forklift straddles the set of rails and enters the wheel between the sets of rails on which oxide powder is deposited. Since the high-temperature object can be carried in and out without performing the above operation, the scattering of the oxide powder during the transportation of the high-temperature object can be reduced.
Then, if the oxide powder deposited between the pair of rails is discharged along the longitudinal direction of the rail, the oxide powder can be easily collected.
As described above, according to the storage facility of the present invention, the oxide powder is less likely to be scattered around, and the recovery rate can be improved.
