Description

Technical Field

[0001] This invention relates to the field of aluminum liquid ladle lifting technology, and more specifically, to a ladle lifting body and a vacuum ladle lifting method. Background Technology

[0002] Currently, the inner lining of aluminum molten metal ladles is typically constructed by layering an insulation board and a layer of castable refractory. Due to structural strength and insulation requirements, the thickness of the castable refractory at the bottom of the lining is much greater than that on the sides, resulting in a heavier ladle. Furthermore, aluminum molten metal deposits and forms impurities inside the ladle, not only occupying internal space but also further increasing its weight. When the ladle is heavy, injecting the same weight of aluminum molten metal will result in a significantly larger overall weight, easily exceeding the lifting equipment's maximum load. Therefore, frequent cleaning of the ladle's bottom residue is necessary, but this high frequency of cleaning can negatively impact aluminum molten metal production efficiency. Summary of the Invention

[0003] The problem solved by this invention is: how to provide a reliable and lightweight aluminum molten metal ladle.

[0004] To address the above problems, the present invention provides a lifting bag body and a vacuum lifting bag.

[0005] In a first aspect, the present invention provides a lifting bag body, comprising a shell, an insulation layer, and a casting layer arranged sequentially from the outside to the inside. The insulation layer includes an insulation board layer and an insulation brick layer. The insulation board layer is laid on the inner bottom wall and inner side wall of the shell. The insulation brick layer is laid on the insulation board layer located on the inner bottom wall of the shell and is located between the insulation board layer and the casting layer. The thickness of the insulation brick layer is greater than the thickness of the insulation board layer and less than the thickness of the casting layer.

[0006] Optionally, the lifting package body further includes a first anchor, one end of which is connected to the inner bottom wall of the shell, and the other end passes through the insulation board layer and the insulation brick layer in sequence and is anchored to the cast layer.

[0007] Optionally, the lifting package further includes a second anchor, one end of which is connected to the inner wall of the shell, and the other end passes through the insulation board layer and is anchored to the cast-in-place layer. Optionally, the insulation brick layer includes a plurality of insulation bricks, and the insulation board layer laid on the inner bottom wall of the shell includes a plurality of first insulation boards. The first anchor is provided with a plurality of first anchors, each of which passes through the gap between two adjacent insulation bricks and / or the gap between two adjacent first insulation boards.

[0008] Optionally, the first anchor includes a straight rod portion and a forked portion connected to each other. The straight rod portion is vertically connected to the inner bottom wall of the housing, and the forked portion is located above the insulating brick and anchored within the cast-in-place layer.

[0009] Optionally, the forked portion includes a first branch segment and a second branch segment, one end of the first branch segment and the second branch segment being connected to the upper end of the straight rod portion, and the other end extending away from each other and away from the insulation brick.

[0010] Optionally, the lifting package body further includes an anti-detachment frame connected to the first anchor. The anti-detachment frame is located above the insulation brick layer and anchored within the cast layer to restrict the upward movement of the insulation brick layer.

[0011] Optionally, the anti-detachment frame includes multiple elongated connecting rods, which are connected in pairs.

[0012] And / or, the anti-detachment frame includes a mesh frame formed by sequentially winding metal wires around each of the first anchors.

[0013] Optionally, the insulation brick layer includes multiple insulation bricks, the insulation board layer includes multiple insulation boards, and the gaps between two adjacent insulation bricks and between two adjacent insulation boards are filled with castable material. And / or, there is a gap between the insulating brick layer and the inner wall of the shell, and the gap is filled with the casting layer.

[0014] Secondly, the present invention provides a vacuum lifting package, comprising the lifting package body as described above.

[0015] The beneficial effects of the bale body of the present invention are as follows: By adding an insulating brick layer between the insulating board layer and the cast-in-place layer of the bale body, while keeping the total thickness of the bale body unchanged, the insulating brick layer with lower thermal conductivity and density replaces part of the cast-in-place layer with higher thermal conductivity and density. This improves the insulation effect of the bale body and reduces its weight. The reduced weight not only lowers the production cost of the bale body but also reduces the frequency of cleaning residue from the bottom of the bale, thus reducing the frequency of bale changes and improving aluminum extraction efficiency. It also reduces the transportation costs of equipment such as bale transport vehicles and forklifts required for cleaning, and reduces the labor intensity of cleaning the bale, improving labor efficiency. Furthermore, the insulating brick layer effectively hinders alumina infiltration, improving the quality and safety of the bale. Furthermore, due to the large sidewall area of ​​the package, laying insulation bricks on the sidewalls would require considerable time, leading to low production efficiency. Therefore, this invention addresses this by placing the insulation brick layer only on the insulation board layer located on the inner bottom wall of the shell, i.e., at the bottom of the package. This reduces the weight and cost of the package while improving production efficiency. Moreover, by setting the thickness of the insulation brick layer to be greater than the thickness of the insulation board layer but less than the thickness of the cast-in-place layer, the internal volume of the package is increased while maintaining its structural strength at the bottom, thereby further reducing the frequency of package replacement and production costs.

[0022] In related technologies, the inner lining of an aluminum molten metal ladle is typically constructed by layering an insulation board and a layer of castable refractory. Due to structural strength and insulation requirements, the thickness of the castable refractory at the bottom of the ladle's inner lining is significantly greater than that on the side walls, resulting in a substantial weight for the ladle itself. Furthermore, aluminum molten metal deposits and forms impurities inside the ladle, not only occupying internal space but also further increasing its weight. When the ladle itself is heavy, injecting the same weight of aluminum molten metal will result in an overall heavier ladle, easily exceeding the lifting equipment's maximum load capacity. Therefore, frequent cleaning of the ladle's bottom residue is necessary, but this high frequency of cleaning can negatively impact aluminum molten metal production efficiency.

[0023] To address the problems existing in the aforementioned related technologies, embodiments of the present invention provide a bag lifting body and a vacuum bag lifting method.

[0024] Combination Figure 1 and Figure 2 As shown, an embodiment of the present invention includes a shell 1, an insulation layer 2, and a casting layer 3 arranged sequentially from the outside to the inside. The insulation layer 2 includes an insulation board layer 21 and an insulation brick layer 22. The insulation board layer 21 is laid on the inner bottom wall and inner side wall of the shell 1. The insulation brick layer 22 is laid on the insulation board layer 21 located on the inner bottom wall of the shell 1 and is located between the insulation board layer 21 and the casting layer 3. The thickness of the insulation brick layer 22 is greater than the thickness of the insulation board layer 21 and less than the thickness of the casting layer 3.

[0025] Specifically, the shell 1 of the carrying bag can be a steel plate structure, the insulation board layer 21 can be made of ceramic insulation board or aluminum silicate fiberboard, the insulation brick layer 22 can be made of high-strength refractory bricks such as high-alumina lightweight bricks or alumina hollow bricks, and the casting layer 3 can be made of non-stick alumina castable, steel fiber castable, or high-alumina castable. The insulation brick layer 22 is laid on the insulation board layer 21 located on the inner bottom wall of the shell 1, and is located between the insulation board layer 21 and the casting layer 3. That is, the insulation brick layer 22 is set at the bottom of the carrying bag, while there is no insulation brick layer 22 on the side walls of the carrying bag. In other words, the bottom of the carrying bag, from the outside to the inside, consists of the shell 1, the insulation board layer 21, the insulation brick layer 22, and the casting layer 3, and the side walls of the carrying bag, from the outside to the inside, consist of the shell 1, the insulation board layer 21, and the casting layer 3. For example, in this embodiment, the insulating brick layer 22 can be constructed of high-strength refractory bricks, and the casting layer 3 can be cast using non-stick aluminum castable. Since the high-strength refractory bricks constituting the insulating brick layer 22 have a thermal conductivity of approximately 0.17 W / mK and a density of approximately 0.6... Up to 0.8 The thermal conductivity of the castable refractory constituting layer 3 is approximately 0.58 W / mK, and its density is approximately 2.38 W / mK. Since the thermal conductivity and density of the insulating brick layer 22 are both less than those of the cast layer 3, using the insulating brick layer 22 to replace part of the cast layer 3 in the bottom of the traditional package can increase the insulation effect of the bottom of the package and reduce the thickness of the cast layer 3 at the bottom of the package, thereby reducing the weight of the package.

[0026] More specifically, the thickness of the insulation board layer 21 of the package is typically set at around 10mm, the thickness of the casting layer 3 is typically set at around 100mm, and the thickness of the insulation brick layer 22 is between 10mm and 100mm. If the thickness of the insulation brick layer 22 is set too small, for example less than the thickness of the insulation board layer 21, the weight of the package will be reduced only slightly, thus failing to achieve the goal of reducing the frequency of package replacement and production costs. If the thickness of the insulation brick layer 22 is set too large, for example greater than the thickness of the casting layer 3, it will not only reduce the internal volume of the package but also reduce the structural strength of the bottom of the package and decrease its load-bearing capacity.

[0027] In this embodiment, an insulating brick layer 22 can be added between the insulating board layer 21 and the cast-in-place layer 3 of the bale body. While maintaining the same total thickness of the bale body, the insulating brick layer 22, with its lower thermal conductivity and density, replaces part of the cast-in-place layer 3, which has higher thermal conductivity and density. This improves the insulation effect of the bale body and reduces its weight. The reduced weight not only lowers production costs but also reduces the frequency of cleaning residue from the bottom of the bale, thus reducing the frequency of bale changes and improving aluminum extraction efficiency. It also reduces transportation costs and expenses associated with cleaning equipment such as bale transport vehicles and forklifts. Furthermore, it reduces the workload of cleaning the bale, improving labor efficiency. Moreover, the insulating brick layer 22 effectively hinders alumina infiltration, improving the quality and safety of the bale. Furthermore, due to the large sidewall area of ​​the package, laying the insulation brick layer 22 on the sidewalls would require a significant amount of time, resulting in low production efficiency. Therefore, in this embodiment, the insulation brick layer 22 is only placed on the insulation board layer 21 located on the inner bottom wall of the shell 1, i.e., the insulation brick layer 22 is placed at the bottom of the package, thereby reducing the weight and cost of the package while improving its production efficiency. Moreover, by setting the thickness of the insulation brick layer 22 to be greater than the thickness of the insulation board layer 21 but less than the thickness of the casting layer 3, the internal volume of the package is increased while ensuring the structural strength of the bottom, further reducing the frequency of package replacement and production costs.

[0028] Optionally, combined Figure 1 As shown, there is a gap between the insulating brick layer 22 and the inner wall of the shell 1, and this gap is filled with a castable layer 3. The insulating brick layer 22 almost covers the entire bottom of the enclosure, meaning the gap between the insulating brick layer 22 and the inner wall of the shell 1 is not too large. This allows for the use of castable refractory material to be poured around the insulating brick layer 22, thus fixing it circumferentially and improving the construction quality of the bottom of the enclosure.

[0029] Optionally, the insulation brick layer 22 includes multiple insulation bricks 221, and the insulation board layer 21 includes multiple insulation boards. The gaps between two adjacent insulation bricks 221 and between two adjacent insulation boards are filled with castable refractory. The insulation boards include a first insulation board 211 laid on the inner bottom wall of the shell 1 and a second insulation board 212 laid on the inner side wall of the shell 1. Two adjacent insulation boards refer to two adjacent first insulation boards 211, two adjacent second insulation boards 212, and adjacent first insulation boards 211 and second insulation boards 212 (i.e., the first insulation board 211 and second insulation board 212 located at the connection between the inner bottom wall and the inner side wall of the shell 1). In this way, the gaps between two adjacent insulation bricks 221 and between two adjacent insulation boards can be filled with castable refractory to fix the insulation board layer 21 and the insulation brick layer 22, thereby improving the overall structural stability of the enclosure. It is understandable that the grout between two adjacent insulation bricks 221 and between two adjacent insulation boards can be poured separately or poured together when pouring the grout layer 3. If poured together, it is equivalent to part of the grout layer 3 being embedded in the gaps between adjacent insulation bricks 221 and between adjacent insulation boards, so that the insulation brick layer 22, the insulation board layer 21 and the grout layer 3 are tightly bonded together, thereby enhancing the structural stability.

[0030] Optionally, combined Figure 1 As shown, the lifting package also includes a first anchor 4. One end of the first anchor 4 is connected to the inner bottom wall of the shell 1, and the other end passes through the insulation board layer 21 and the insulation brick layer 22 in sequence and is anchored to the casting layer 3. The first anchor 4 can be fixed to the inner bottom wall of the shell 1 by, for example, welding. In this way, after the casting layer 3 is poured, the first anchor 4 can be used to anchor the casting layer 3 on the inner bottom wall of the shell 1, preventing the casting layer 3 from loosening, thereby forming a stable bottom structure and improving the strength and quality of the package. Furthermore, by placing the first anchor 4 on the inner bottom wall of the shell 1, the first anchor 4 can simultaneously anchor the casting layer 3 and fix the insulation brick layer 22, preventing the insulation brick layer 22 from shaking and affecting the casting quality.

[0031] Optionally, combined Figure 2 and Figure 3 As shown, the insulation brick layer 22 includes a plurality of insulation bricks 221, and the insulation board layer 21 laid on the inner bottom wall of the shell 1 includes a plurality of first insulation boards 211. A plurality of first anchors 4 are provided, and each first anchor 4 passes through the gap between two adjacent insulation bricks 221 and / or the gap between two adjacent first insulation boards 211.

[0032] Specifically, the multiple insulation bricks 221 can be distributed in multiple rows and columns, or in multiple rings, or in multiple rows, with adjacent rows of insulation bricks 221 staggered; the multiple first insulation boards 211 can be distributed in multiple rows or columns, or in the same way as the multiple insulation bricks 221, without specific limitations here.

[0033] In this way, by setting multiple first anchors 4 on the inner bottom wall of the shell 1, the anchoring effect on the cast layer 3 is improved; by passing each first anchor 4 through the gap between two adjacent insulation bricks 221 and / or the gap between two adjacent first insulation boards 211, it is not necessary to open through holes in the insulation bricks 221 and / or the first insulation boards 211 for the first anchors 4 to pass through, thereby ensuring the integrity of the insulation bricks 221 and / or the first insulation boards 211, making the bottom of the casing have high structural strength, and at the same time, reducing the difficulty of laying the insulation bricks 221 and / or the first insulation boards 211 and improving the laying efficiency.

[0034] Optionally, combining 2 and Figure 3 As shown, multiple insulation bricks 221 are arranged in multiple rows and columns, multiple first anchors 4 are arranged in multiple rows and columns, and a row of first anchors 4 is provided between every two adjacent rows of insulation bricks 221, and a row or column of first anchors 4 is provided between every two adjacent first insulation boards 211.

[0035] It should be noted that the gap formed between any two adjacent rows of first anchors 4 and the gap formed between the two outermost rows of first anchors 4 and the inner wall of the shell 1 are called transverse gaps, and the gap formed between any two adjacent columns of first anchors 4 and the gap formed between the two outermost columns of first anchors 4 and the inner wall of the shell 1 are called longitudinal gaps. Thus, multiple rows and columns of first anchors 4 can form multiple transverse gaps and multiple longitudinal gaps.

[0036] It should also be noted that the number of first anchors 4 in each row or column can be the same or different. That is to say, the lengths of multiple transverse gaps and multiple longitudinal gaps can be the same or different. In other words, the lengths of multiple first insulation boards 211 laid in the transverse gaps or longitudinal gaps can be the same or different.

[0037] In this optional embodiment, by arranging multiple first anchors 4 in multiple rows and columns, the first insulation board 211 is laid in the transverse gaps formed between the multiple rows of first anchors 4 or the longitudinal gaps formed between the multiple columns of first anchors 4, thereby improving the convenience of laying the insulation board at the bottom of the shell 1. The multiple first insulation boards 211 can be laid in multiple transverse gaps respectively, in which case a row of first anchors 4 is provided between every two adjacent first insulation boards 211; the multiple first insulation boards 211 can also be laid in multiple longitudinal gaps respectively, in which case a column of first anchors 4 is provided between every two adjacent first insulation boards 211, and since a column of first anchors 4 is provided between every two adjacent columns of insulation bricks 221, a column of insulation bricks 221 is laid on each first insulation board 211. In this way, the insulation board layer 21 and the insulation brick layer 22 are laid at the bottom of the shell 1, and the laying efficiency is high.

[0038] Furthermore, combined Figure 2 As shown, the insulation board layer 21 laid on the inner wall of the shell 1 includes multiple second insulation boards 212 arranged in a ring shape along the vertical direction. Each second insulation board 212 can be a single continuous and closed ring-shaped insulation board, or it can be composed of multiple insulation boards forming a closed ring structure; no specific limitation is made here. Furthermore, the multiple ring-shaped second insulation boards 212 are arranged vertically. Compared to using long strips of insulation boards arranged sequentially along the circumference of the shell 1's side wall, this arrangement is not only easier to lay, but also allows the weight of the upper ring-shaped insulation boards to press against the lower ring-shaped insulation boards, thereby reducing the assembly gap between the individual ring-shaped insulation boards and improving the laying effect.

[0039] Optionally, combined Figure 1 and Figure 4 As shown, the package body also includes a second anchor 6. One end of the second anchor 6 is connected to the inner wall of the shell 1, and the other end passes through the insulation layer 21 and is anchored to the cast layer 3. The second anchor 6 can be fixed to the inner wall of the shell 1 by, for example, welding. Thus, after the cast layer 3 is cast, the second anchor 6 on the inner wall of the shell 1 can be used to anchor the cast layer 3 on the inner wall of the shell 1, preventing the cast layer 3 from loosening, thereby forming a stable sidewall structure for the package body, and thus improving the strength and quality of the package body.

[0040] During production, the first anchor 4 can be welded to the inner bottom wall of the shell 1 first, then the first insulation board 211 and the second insulation board 212 can be laid to form the insulation board layer 21, followed by the laying of insulation bricks 221 to form the insulation brick layer 22, and finally the castable refractory can be poured to form the casting layer 3. Alternatively, the first anchor 4 and the second anchor 6 can be welded to the inner bottom wall and the inner side wall of the shell 1 respectively, then the insulation board layer 21 and the insulation brick layer 22 can be laid in sequence, and finally the castable refractory can be poured to form the casting layer 3.

[0041] Optionally, combined Figure 1 As shown, the first anchor 4 includes a straight rod portion 41 and a forked portion 42 connected to each other. The straight rod portion 41 is vertically connected to the inner bottom wall of the shell 1, and the forked portion 42 is located above the insulation brick 221 and is anchored in the casting layer 3.

[0042] In this optional embodiment, the first anchor 4 can be a Y-shaped structure, in which case the forked portion 42 has a V-shaped structure, and the upper end of the straight rod portion 41 is connected to the intersecting end of the V-shaped structure. Alternatively, the first anchor 4 can be a T-shaped structure, in which case the forked portion 42 has an "I"-shaped structure, and the upper end of the straight rod portion 41 is connected to the middle position of the "I"-shaped structure. Thus, by configuring the first anchor 4 to include the straight rod portion 41 and the forked portion 42, the first anchor 4 not only has a simple structure but also high stability. Furthermore, by anchoring the forked portion 42 within the cast-in-place layer 3, the anchoring effect of the first anchor 4 can be improved. In addition, by placing the forked portion 42 of the first anchor 4 above the insulation brick 221, the smaller straight portion 41 in the gap width direction is located in the gap between two adjacent rows of insulation bricks 221, while the larger forked portion 42 in the gap width direction is located outside the gap. This reduces the gap between the insulation bricks 221, allowing the insulation bricks 221 to be laid more tightly. This not only enhances the anti-alumina effect but also improves the stability of the insulation brick layer 22.

[0043] Furthermore, the dimension of the straight rod portion 41 along the set direction can be set to be equal to the spacing between two adjacent rows of insulation bricks 221, wherein the set direction is parallel to the arrangement direction of multiple insulation bricks 221 in each row of insulation bricks 221. In this way, it can be ensured that the straight rod portion 41 of the first anchor 4 located in the gap between two adjacent rows of insulation bricks 221 can contact the side of the insulation brick 221, that is, the straight rod portion 41 of the first anchor 4 is sandwiched between two adjacent rows of insulation bricks 221. On the one hand, it can further reduce the gap between the insulation bricks 221, thereby further improving the tightness of the insulation brick layer 22. On the other hand, it can use the two adjacent rows of first anchors 4 to limit the insulation bricks 221 located between the two adjacent rows of first anchors 4, preventing the insulation bricks 221 from loosening when the pouring layer 3 is poured.

[0044] Furthermore, the direction of the forked portion 42 of the first anchor 4 can be arbitrarily arranged, so that the connection force between all the first anchors 4 and the cast layer 3 is more uniform.

[0045] Furthermore, combined Figure 1As shown, the structure of the second anchor 6 can be the same as that of the first anchor 4. In this case, the second anchor 6 includes a second straight rod portion and a second forked portion connected to each other. The second straight rod portion is vertically connected to the inner wall of the shell 1, and the second forked portion is located on the side of the second insulation plate 212 away from the inner wall of the shell 1 and is anchored in the cast-in-place layer 3. This arrangement not only simplifies the structure of the second anchor 6 but also improves its anchoring effect.

[0046] Furthermore, the gaps between adjacent rows of insulation bricks 221 and between adjacent columns of insulation bricks 221 are filled with a casting layer 3. After the insulation board layer 21 and the insulation brick layer 22 are laid, when casting with castable refractory, the fluid refractory flows into and fills the gaps between adjacent insulation bricks 221. Once the refractory has solidified, it can fix the insulation bricks 221, thus forming a highly stable base structure.

[0047] Optionally, combining 1 and Figure 4 As shown, the forked portion 42 includes a first branch segment 421 and a second branch segment 422. One end of the first branch segment 421 and the second branch segment 422 are respectively connected to the upper end of the straight rod portion 41, and the other end extends away from each other and away from the insulation brick 221.

[0048] In this optional embodiment, the forked portion 42 includes two branch segments, namely a first branch segment 421 and a second branch segment 422. One end of the first branch segment 421 and the second branch segment 422 intersects at one point and is respectively connected to the upper end of the straight rod portion 41. The other end extends away from each other and away from the insulation brick 221, so that the first branch segment 421 and the second branch segment 422 form a V-shaped structure, thereby making the first anchor 4 have a Y-shaped structure. In this way, not only is the structure simple, but it can also increase the connection area between the forked portion 42 of the first anchor 4 and the cast layer 3, that is, increase the embedded contact area between the forked portion 42 and the cast layer 3, ensuring the stability of the cast layer 3. At the same time, it is also convenient to use the first branch segment 421 and the second branch segment 422 to respectively limit the upward movement of two adjacent columns or two rows of insulation bricks 221, that is, restrict the upward movement of the insulation bricks 221, thereby improving the stability of the insulation brick layer 22.

[0049] In other embodiments, the forked portion 42 may also include three or more branch segments. This further increases the connection area between the first anchor 4 and the cast-in-place layer 3, thereby improving the stability of the cast-in-place layer 3.

[0050] Optionally, combined Figure 2 and Figure 3As shown, the lifting package also includes an anti-detachment frame 5 connected to the first anchor 4. The anti-detachment frame 5 is located above the insulation brick layer 22 and anchored within the cast-in-place layer 3 to restrict the upward movement of the insulation brick layer 22. The anti-detachment frame 5 can be welded to the fork 42 of the first anchor 4. Thus, by setting the anti-detachment frame 5, the insulation brick layer 22 is further secured, thereby improving its stability and reducing the risk of the cast-in-place blocks falling off.

[0051] Optionally, combined Figure 3 As shown, the anti-detachment frame 5 includes multiple long strip-shaped connecting rods 51, which are connected in pairs.

[0052] In this optional embodiment, each link 51 is connected to the fork 42 of a portion of the first anchor 4, and the length of the link 51 is approximately equal to the distance between the opposite ends of the insulation brick layer 22. For example, when the insulation brick layer 22 is a disc-shaped structure, the length of the link 51 is close to the diameter of the disc. The pairwise cross-connection of multiple links 51 can be understood as multiple links 51 forming an intersecting section, i.e., multiple links 51 intersecting at one point, or forming multiple intersecting sections. For example, in one example, such as... Figure 2 As shown, the anti-detachment frame 5 includes two connecting rods 51, which are connected to form a cross shape. In another example, the anti-detachment frame 5 includes four connecting rods 51, which can be connected to form a star shape or a grid shape. Thus, using multiple connecting rods 51 connected in pairs to fix the insulation brick layer 22 simplifies the structure of the anti-detachment frame 5 and facilitates production and assembly.

[0053] Optionally, the anti-detachment frame 5 includes a mesh frame formed by sequentially winding metal wires around each of the first anchors 4.

[0054] In this optional embodiment, the metal wire is typically iron wire and is wound around the forked portion 42 of the first anchor 4. Since multiple intersecting connecting rods 51 can typically only connect a portion of the first anchor 4 and cannot cover all of them, in this embodiment, the metal wire is sequentially wound around the forked portion 42 of each first anchor 4 to form a mesh frame. This mesh frame not only connects all the first anchors 4 to each other but also forms a "cage" structure with the insulation board layer 21 to fix the insulation brick layer 22. This not only further strengthens the fixation of the insulation brick layer 22 but also reduces the risk of the castable blocks falling off, thereby further improving the stability of the bottom structure of the enclosure.

[0055] An embodiment of the present invention provides a vacuum lifting package, comprising the lifting package body as described above.

[0056] The beneficial effects of the vacuum lifting bag in this embodiment are the same as those of the lifting bag body described above, and will not be repeated here.

[0057] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
