For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In addition, it should be noted that in the description of the present invention, it should be noted that the terminology nouns in the various embodiments, such as "upper", "lower", "front", "back" and other words indicating directions, are only for simplifying the description of the positional relationship based on the drawings in the specification, and do not mean that the components and devices referred to must be operated in accordance with the specific directions and specified operations and methods and structures in the specification. Such directional nouns do not constitute a limitation on the present invention.

[0029] Herein, an XYZ axis is established, wherein the positive direction of the X axis represents the front, the reverse direction of the X axis represents the right, the positive direction of the Y axis represents the left, the reverse direction of the Y axis represents the right, the positive direction of the Z axis represents the top, and the reverse direction of the Z axis represents the bottom. It should be noted that the aforementioned X axis, Y axis, and Z axis are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0030] like Figure 1-Figure 3 As shown, a transfer device of an embodiment of the utility model includes a transfer box 1, wherein the transfer box 1 includes a box body 11, wherein the box body 11 is provided with a storage space, wherein at least one of the inner wall surfaces of the storage space is a corrugated surface, and the storage space has an opening 111, and the storage space is a tapered structure from close to the opening 111 to away from the opening 111.

[0031] Specifically, the box body 11 can be rotatably arranged on the frame 2, and the box body 11 can be rotated relative to the frame 2 around the axis shown by the Y axis to switch back and forth between a horizontal state and a position inclined relative to the horizontal plane. The box body 11 is provided with a storage space for accommodating materials such as electrolytes and aluminum ash slag, and the storage space has an opening 111. Molten electrolytes and aluminum ash slag and other materials can be placed into the storage space through the opening 111, and the materials in the storage space can be poured out from the opening 111. When the box body 11 is in a horizontal state, the opening 111 is arranged upward. The box body 11 can be formed by enclosing a plurality of channel steels, and the storage space is a tapered structure from close to the opening 111 to away from the opening 111, that is, the size of the open end of the storage space is larger and the size of the bottom is smaller.

[0032] In this embodiment, the box body 11 of the transfer box 1 can be rotatably set on the frame 2, and the storage space of the box body 11 has at least one corrugated inner wall surface. Compared with the flat wall surfaces, the heat dissipation area of ​​the storage space is increased, and the stress concentration caused by the heat of the box body 11 is reduced, thereby effectively reducing the deformation risk or deformation amount of the box body 11, and preventing materials such as electrolytes and aluminum ash from being stuck in the box body 11 after condensation. When the transfer device is pushed into place and the box body 11 is flipped relative to the frame 2, the materials inside can be smoothly poured out from the opening 111 under the action of gravity. At the same time, compared with the rectangular structure of the accommodating space, the accommodating space of the box body 11 of the present embodiment is a tapered structure from close to the opening 111 to away from the opening 111, and the angles between the side walls and the bottom wall of the accommodating space are relatively large, which makes it difficult to form a stacking dead zone. When the box body 11 is turned over, the material inside is further prompted to pour out from the opening 111 under the action of gravity, so that the transfer efficiency is higher, there is no need to manually hammer the transfer box 1, the labor intensity is lower, and it is not easy to damage the transfer device.

[0033] Optionally, the box body 11 is made of heat-resistant cast iron; and / or the inner wall surface of the accommodating space includes a bottom wall surface arranged opposite to the opening 111, and the bottom wall surface is a corrugated surface.

[0034] In this embodiment, the heat-resistant cast iron has high heat resistance and can be used in high temperature environments. It is not easily deformed when transporting high-temperature molten electrolyte and aluminum ash slag, which increases the service life and reduces equipment maintenance costs.

[0035] The bottom wall of the accommodation space is a corrugated surface, which can increase the contact area with the material compared to a flat surface, that is, increase the heat dissipation area of ​​the bottom wall, reduce thermal stress, and avoid deformation and damage of the bottom wall. In some other embodiments, the side wall of the accommodation space can also be set to a corrugated surface as needed.

[0036] like Figure 1-Figure 4 As shown, optionally, the transfer device also includes a frame 2 and a rotating shaft 3, the frame 2 includes two frames 21 arranged opposite to each other, the box body 11 is at least partially located between the two frames 21, and the two frames 21 are rotatably connected to the two side walls of the box body 11 through the corresponding rotating shaft 3.

[0037] Specifically, the two frames 21 can be spaced and arranged opposite to each other along the direction indicated by the Y axis. The frames 21 can be a frame structure formed by enclosing a plurality of cross-arranged channel steels. The box body 11 is at least partially located between the two frames 21, including two situations: the box body 11 is completely located between the two frames 21; or the box body 11 is partially located between the two frames 21 and partially extends out of the frames 21. With this arrangement, the larger box body 11 can be installed while the smaller frame 2 is arranged, thereby increasing the material placement space. The rotating shaft 3 is arranged along the direction indicated by the Y axis, and the rotating shaft 3 is a circular shaft.

[0038] In this embodiment, the rotating shaft 3 is used to realize the rotation connection between the box body 11 and the frame 21, and the connection method is simple and convenient. At the same time, the left and right sides of the box body 11 are respectively rotatably connected to the corresponding frame 21 through the corresponding rotating shaft 3, which can improve the rotation connection stability between the box body 11 and the frame 21.

[0039] In some embodiments, the frame 2 may include a frame body 21 , and the box body 11 is located on one side of the frame body 21 and is rotatably connected to the frame body 21 , and the structure is relatively simple.

[0040] like Figure 2 and Figure 4 As shown, optionally, part of the box body 11 extends out from between the first ends 211 of the two frames 21 , and the first end 211 of each frame 21 is rotatably connected to a side wall of the box body 11 .

[0041] In this embodiment, one end of the frame 21 along the positive direction of the X-axis is the first end 211 of the frame 21. Since part of the box body 11 extends from between the first ends 211 of the two frames 21, the first end 211 of each frame 21 is rotatably connected to a side wall of the box body 11 through the corresponding rotating shaft 3, that is, the middle part of the left and right side walls of the box body 11 is rotatably connected to the frame 21. Compared with the case where one end of the box body 11 is rotatably connected to the frame 21, the box body 11 is more convenient and labor-saving when tipping.

[0042] like Figure 2-Figure 3 As shown, optionally, the frame 2 also includes a first baffle 22, which is arranged between the two frame bodies 21, and the first baffle 22 is located below the rotating shaft 3. The first baffle 22 is used to abut against the box body 11 when the box body 11 is flipped along the first direction to limit the flipping angle of the box body 11 along the first direction.

[0043] Specifically, the first baffle 22 is extended along the direction indicated by the Y axis, and is disposed between the front and lower parts of the two frames 21. The first baffle 22 can be made of channel steel. The first baffle 22 is located below the rotation axis 3, and the distance between the first baffle 22 and the rotation axis 3 is less than or equal to the distance between the rotation axis 3 and the front end of the box body 11, so that the box body 11 can abut against the first baffle 22 when rotating around the rotation axis 3 in the first direction. The first direction can be understood as Figure 1 The middle box body 11 rotates clockwise.

[0044] In this embodiment, the box body 11 can be turned clockwise from a horizontal state to abut against the first baffle 22, and the first baffle 22 is used to limit the turning angle of the box body 11 in the clockwise direction to avoid the turning angle being too large and unable to reset. The position of the first baffle 22 can be flexibly set according to the turning angle requirements. Generally, the box body 11 can be turned 100° clockwise around the rotation axis 3.

[0045] like Figure 2-Figure 3 As shown, optionally, the frame 2 also includes a second baffle 23, which is arranged between the second ends 212 of the two frames 21 away from the first ends 211, and the second baffle 23 is used to abut against the box body 11 when the box body 11 is flipped along the second direction to support the box body 11 upward.

[0046] Specifically, the second baffle plate 23 is extended along the direction indicated by the Y axis. The second baffle plate 23 is disposed between the upper rear portions of the two frames 21 . The second baffle plate 23 may be made of channel steel.

[0047] In this embodiment, the second baffle 23 is higher than the first baffle 22, that is, the second baffle 23 is set at a higher position. On the one hand, when the box body 11 is in the initial horizontal state, the second baffle 23 can contact the bottom wall or inclined side wall of the box body 11, and can provide an upward support force for the box body 11 to prevent the box body 11 from tilting backward and downward; on the other hand, after the box body 11 is dumped, when it flips along the second direction to return to the initial horizontal state, it can be used to abut against the second baffle 23 to limit the flipping angle along the second direction so that it can be smoothly reset. The second direction is the opposite direction of the first direction, and the second direction can be understood as Figure 1 The middle box body 11 rotates counterclockwise.

[0048] In addition, channel steel may be welded between the rear lower parts of the two frames 21 to improve the overall strength of the fixed frame 2 .

[0049] like Figure 1-Figure 2 As shown, optionally, the transfer device further includes a locking member 4, and the locking member 4 is used to lock the box body 11 and the frame 2 relative to each other.

[0050] In this embodiment, one or more locking members 4 may be provided, and may be provided on one or more sides of the frame 2. When it is not necessary to dump the material, the locking member 4 may lock the transfer box 1 relative to the frame 2 to prevent the material in the box from accidentally tipping over; when it is necessary to dump the material, the locking member 4 is unlocked to facilitate the flipping of the transfer box 1.

[0051] like Figure 5 As shown, optionally, the locking member 4 includes a seat body 41 and a sliding rod 42, the seat body 41 is arranged on the frame body 21, and the sliding rod 42 is slidably arranged on the seat body 41, and the sliding rod 42 is used to at least partially slide to the top of the box body 11 when the box body 11 abuts against the second baffle 23, so as to limit the box body 11 from flipping in the direction away from the second baffle 23.

[0052] Specifically, take the example of the locking member 4 being arranged on the left and right sides of the box body 11, the seat body 41 is installed on the upper end surface of the frame body 21, and the slide bar 42 is arranged on the seat body 41 for sliding along the Y direction. When the box body 11 flips in the counterclockwise direction to abut against the second baffle 23 after unloading, the slide bar 42 can slide along the Y direction and partially extend to the top of the box body 11, limiting the box body 11 from tipping forward. At the same time, the box body 11 is limited between the second baffle 23 and the slide bar 42 and will not shake, thereby achieving the locking of the box body 11.

[0053] Furthermore, the seat body 41 includes two card slot seats arranged in a centrally symmetrical manner, the card slot seats are L-shaped, and a Z-shaped card slot with a notch facing upward is formed between the two card slot seats. The Z-shaped card slot includes a first card slot 412, a second card slot 413 and a third card slot 414 that are interconnected. The first card slot 412 and the third card slot 414 are both arranged along the X direction, and the second card slot 413 is arranged along the Y direction. The interiors of the two card slot seats are respectively provided with mounting holes 411 that penetrate along the Y direction. The slide rod 42 is slidably arranged in the mounting hole 411, and a card block 421 is provided on the slide rod 42. The card block 421 is used to be inserted into the card slot and to be used to move between the first card slot 412, the second card slot 413 and the third card slot 414. Specifically, initially the card block 421 is located in the third card slot 414. When locking is required, the card block 421 is first rotated around the Y-axis to make it withdraw from the third card slot 414, and then the card block 421 is pushed inward to make the slide bar 42 slide along the Y direction toward the transfer box 1, and then the card block 421 is rotated around the Y-axis to make it fit into the first card slot 412, thereby realizing relative locking between the transfer box 1 and the frame 2; the unlocking process is the opposite, and the card block 421 is moved from the first card slot 412 to the third card slot 414.

[0054] In this embodiment, when there is no need to dump the material, the slide bar 42 can be slid in the direction close to the transfer box 1, and the transfer box 1 is restricted between the slide bar 42 and the second baffle 23, so that the transfer box 1 and the frame 2 are relatively locked to avoid accidental tipping of the material in the box; when it is necessary to dump the material, the slide bar 42 can be slid in the direction away from the transfer box 1, so that the transfer box 1 and the frame 2 are unlocked, so as to facilitate the forward flipping of the transfer box 1.

[0055] In addition, the center of gravity of the box body 11 can be eccentrically set according to actual needs, so that the center of gravity of the box body 11 is biased towards the side of the flipping and dumping direction relative to the axis of the rotating shaft 3, that is, Figure 1 The middle box body 11 is used to abut against the side of the first baffle 22, so that when it is necessary to dump materials, you only need to slide the slide bar to unlock it, and the box body 11 can automatically flip over and dump using the center of gravity offset. After dumping, the empty box body 11 only needs to be manually flipped back and then locked. By setting the center of gravity eccentrically, the purpose of facilitating flipping can be achieved and the efficiency of material dumping can be improved; and because the box body 11 will be slightly tilted when not locked, the operator can visually observe whether the box body 11 is tilted to determine whether the box body 11 is locked, which makes it easier for the operator to ensure that the box body 11 is in a locked state when loading materials and transporting to prevent accidents.

[0056] In some embodiments, the Z-shaped slot may be directly processed on the seat body 41 . The principle is similar to that described above and will not be described again.

[0057] In some other embodiments, the locking member 4 may be a bolt, and threaded holes are respectively processed on the frame 2 and the transfer box 1 , and the bolts are passed through the corresponding threaded holes to achieve relative locking between the transfer box 1 and the frame 2 .

[0058] like Figure 1-Figure 3 As shown, optionally, the transfer box 1 further includes a reinforcing plate 12 , and the reinforcing plate 12 is provided on the box body 11 at the circumferential edge of the opening 111 , and the reinforcing plate 12 is rotatably connected to the frame 21 via the rotating shaft 3 .

[0059] Specifically, the reinforcing plate 12 can be made of channel steel, which is simple to make and has high strength. The reinforcing plate 12 is arranged one by one corresponding to the side plate of the box body 11. The reinforcing plate 12 is a channel-shaped structure. The box body 11 has an opening 111 on the top, and the circumferential edge of the opening 111 extends with a flange. The reinforcing plate 12 is located below the flange, and the top of the reinforcing plate 12 is in contact with the flange and fastened by bolts.

[0060] In this embodiment, a reinforcing plate 12 is provided at the edge of the opening 111 of the box body 11, which is beneficial to improving the strength of the box body 11 at the circumferential edge of the opening 111. The left and right sides of the box body 11 are rotatably connected to the corresponding frame 21 through the reinforcing plate 12, respectively, and can also ensure the connection stability between the transfer box 1 and the frame 2.

[0061] In some embodiments, a bearing 8 may be provided, one end of the rotating shaft 3 extends into the channel steel formed into the reinforcing plate 12, and is rotatably connected to the reinforcing plate 12 through the corresponding bearing 8, and the other end of the rotating shaft 3 extends into the channel steel above the frame 2, and is rotatably connected to the frame 2 through the corresponding bearing 8. The use of the bearing 8 can reduce the friction force during the tipping process of the transfer box 1.

[0062] like Figure 1 As shown, optionally, the transfer device further includes running wheels 5, which are arranged at the bottom of the frame 2. The running wheels 5 are universal wheels, and four running wheels 5 are arranged, which are located at the four corners of the bottom of the frame 2. The transfer device can travel through the running wheels 5, wherein the universal wheels have anti-skid locks to prevent the transfer device from sliding or rolling when it is pushed into place, that is, when loading or unloading.

[0063] like Figure 1 As shown, the transfer device further includes a first handle 6, which is disposed on the frame 2. The first handle 6 can be disposed on the rear side of the frame 2, and the first handle 6 can be U-shaped, with both ends of the first handle 6 respectively connected to the left and right sides of the frame 2, and the transfer device can be pushed to move by the first handle 6.

[0064] like Figure 1 As shown, the transfer device also includes a second handle 7, which is arranged on the transfer box 1. The second handle 7 can be arranged at the rear of the box body 11, so as to facilitate the application of a downward turning force from the back to the front. The second handle 7 can be an arc-shaped handle, which matches the ergonomic design and improves the comfort of holding. After the transfer device is pushed into place, the second handle 7 can be used to apply a force to the transfer box 1 to make it tip over and unload.

[0065] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
