Description

Technical Field

[0001] This invention relates to the field of autoclaved aerated concrete (AAC) production technology, specifically to an AAC production line and an AAC production method. Background Technology

[0002] Autoclaved aerated concrete (ALC) is a new type of building material produced using sand, cement, lime, gypsum, and aluminum powder as materials. Its products are divided into blocks and panels, both of which have the same production process and main equipment. The production process includes:

[0003] Raw material processing: The raw materials for ALC, sand, cement, lime, gypsum, water and aluminum powder, are stored. The sand is prepared into slurry through wet ball milling.

[0004] Ingredient batching and mixing: The automatic batching and mixing system can accurately batch, measure, and mix all raw materials. The mixed slurry is injected into the mold, where it expands and forms a blank containing countless tiny pores.

[0005] Cutting: Once the blank has gained sufficient strength, it is removed from the mold and precisely cut using wire or a knife to form blocks or wall panels. The tenons and grooves are completed before the blank is steam-pressed, thus preventing the generation of waste material after hardening.

[0006] Autoclaving: After cutting, the aerated concrete products are autoclaved in saturated steam at 180-190℃. Under high temperature and pressure conditions, the green body forms a unique crystal structure, giving the product high strength and dimensional stability.

[0007] Sorting and Packaging: Once autoclaving is complete, aerated concrete blocks or panels are stacked, packaged, and transported to the construction site.

[0008] The layout of an ALC production line requires a relatively large site area. The production line includes four different production carriers that move and transport materials along the line: mold carts, side template carts, steam curing carts, and saddle frames. The side templates can also be referred to as base plates.

[0009] In existing technologies, ALC production lines mainly employ cross-cutting and cross-steaming processes and cross-cutting and vertical steaming processes. When an ALC production line uses the cross-cutting and cross-steaming process, the billet, after passing through the cutting machine, undergoes the following stages under the support of the steaming and curing base plate:

[0010] ① The blank is cut by a cutting machine;

[0011] ②After the bottom plate and billet are flipped on the turning table to remove the bottom skin, they are flipped back;

[0012] ③ The bottom plate and billet are transferred from the tilting table to the autoclave using a crane;

[0013] ④ After each steam curing trolley is loaded with 3 mold base plates and billets, it enters the grouping area in front of the autoclave;

[0014] ⑤ The six steam curing carts in the grouping area enter the steam curing kettle for steam curing;

[0015] ⑥ After steam curing is completed, the steam curing trolley and the green body are pulled out of the steam curing kettle and then enter the area behind the kettle;

[0016] ⑦ The base plate and finished product on the steam curing trolley are placed onto the conveyor line via a transfer car and a finished product crane;

[0017] ⑧ The bottom plate and finished product are passed through the plate breaking machine, and the finished product is broken into pieces;

[0018] ⑨ The base plate and finished product are sent to the single-mold clamping machine station. The product is clamped away by the clamping machine, and the base plate enters the storage warehouse via the return line.

[0019] The transverse cutting and vertical steaming process uses a steaming frame to support the billet for steaming. Because the carriers supporting the billet are different during steaming, currently, an ALC production line can only realize one method of production: transverse steaming or vertical steaming. One production line is needed for transverse steaming and another for vertical steaming. Each ALC production line has a single production method, and two production lines occupy a large area and have high costs. Summary of the Invention

[0020] Therefore, the technical problem to be solved by the present invention is to overcome the defect that an existing ALC production line can only realize production in one mode, either horizontal or vertical steaming, resulting in a single production method, thereby providing an aerated concrete production line and an aerated concrete production method.

[0025] Optionally, the steam curing frame transfer device includes a first steam curing frame conveyor line, which is used to receive empty steam curing frames on the finished product turning table and convey the empty steam curing frames.

[0026] Optionally, the steam curing frame transfer device also includes a second steam curing frame conveyor line, which is used to transport empty steam curing frames to the semi-finished product turning table.

[0027] Optionally, the aerated concrete production line also includes a curing frame storage unit and a curing frame stacking device.

[0058] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0059] like Figures 1 to 10As shown, the aerated concrete production line of this embodiment includes: a semi-finished product transfer device, a semi-finished product turning table 11, a finished product transfer device, and a finished product turning table 12. The semi-finished product transfer device has a horizontal and vertical steaming transfer state for transferring the cut billet 61 and base plate 62 to the semi-finished product turning table 11, and also has a horizontal steaming semi-finished product transfer state for transferring the base plate 62 and billet 61 on the semi-finished product turning table 11 to the steaming and curing cart 64, and also has a vertical steaming semi-finished product transfer state for transferring the steaming frame 63 and billet 61 on the semi-finished product turning table 11 to the steaming and curing cart 64. The semi-finished product turning table 11 has a horizontal steaming semi-finished product turning state for first turning the base plate 62 and billet 61 on it forward by 90° and then turning it in the opposite direction by 90°, and also has a horizontal steaming semi-finished product turning state for turning the billet 62 and billet 61 on it forward by 90° and then turning it in the opposite direction by 90°. 1. The vertically steamed semi-finished product is transferred from the base plate 62 to the steaming frame 63 in a flipped state; the finished product transfer device and the semi-finished product transfer device are arranged alternately. The finished product transfer device has a horizontally steamed finished product transfer state that transfers the base plate 62 and the blank 61 on the steaming cart 64 after steaming, and also has a first vertically steamed finished product transfer state that transfers the steaming frame 63 and the blank 61 on the steaming cart 64 after steaming to the finished product flipping table 12, and also has a second vertically steamed finished product transfer state that transfers the base plate 62 and the blank 61 on the finished product flipping table 12 out; the finished product flipping table 12 and the semi-finished product flipping table 11 are arranged alternately along a preset direction. The finished product flipping table 12 has a vertically steamed finished product flipping state that transfers the blank 61 on it from the steaming frame 63 to the base plate 62.

[0060] In the aerated concrete production line of this embodiment, when the production line is undergoing transverse steaming, the cut billet 61 and base plate 62 are transferred to the semi-finished product turning table 11 via a semi-finished product transfer device. Then, the semi-finished product turning table 11 rotates the base plate 62 and billet 61 90° in the forward direction, removing the bottom layer between them. Next, the semi-finished product turning table 11 rotates the base plate 62 and billet 61 90° in the reverse direction. Finally, the semi-finished product transfer device transfers the base plate 62 and billet 61 from the semi-finished product turning table 11 to the steam curing cart 64. When steaming... After the curing cart 64 is loaded with three sets of base plates 62 and billets 61, it is controlled to enter the curing kettle 48 along with the base plates 62 and billets 61. The curing kettle 48 performs high-temperature and high-pressure curing on the billets 61. After curing, the curing cart 64, carrying the three sets of base plates 62 and billets 61, stops on one side of the finished product turning table 12. The base plates 62 and billets 61 on the curing cart 64 are then transferred out by the finished product transfer device. When the production line is performing vertical curing, the cut billets 61 and base plates 62 are transferred to the semi-finished product turning table 11 by the semi-finished product transfer device. At the same time, the empty curing frame is... The blank 63 is transferred to the semi-finished product turning table 11. The semi-finished product turning table 11 rotates the bottom plate 62 and the blank 61 90° in the forward direction. This can remove the bottom skin between the bottom plate 62 and the blank 61, or transfer the blank 61 from the bottom plate 62 to the curing frame 63. Then, the curing frame 63 and the blank 61 on the semi-finished product turning table 11 are transferred to the curing cart 64 by the semi-finished product transfer device. When the curing cart 64 has three sets of curing frames 63 and blanks 61, the curing cart 64 and the curing frames 63 and blanks 61 on it are controlled to enter the curing kettle 48. The curing kettle 48 then heats the blanks. 61. High-temperature and high-pressure steam curing is performed. After steam curing, the steam curing cart 64, carrying three sets of steam curing frames 63 and green bodies 61, stops on one side of the finished product turning table 12. The steam curing frames 63 and green bodies 61 on the steam curing cart 64 are transferred to the finished product turning table 12 via the finished product transfer device. At the same time, the empty bottom plate is transferred to the finished product turning table 12. Then, the finished product turning table 12 rotates the steam curing frames 63 and green bodies 61 90° in the forward direction, transferring the green bodies 61 from the steam curing frames 63 to the bottom plate 62. The bottom plate 62 and green bodies 61 on the finished product turning table 12 are then transferred out via the finished product transfer device. By reasonably controlling the semi-finished product turning table 11 and the finished product turning table 12, both horizontal and vertical steaming can be carried out simultaneously. Furthermore, this production line can produce blocks and boards, thus achieving multi-purpose production and saving production line floor space and costs.

[0061] In this embodiment, the aerated concrete production line also includes a steam curing kettle 48, which is used to steam-cur the green bodies 61 on the steam curing cart 64. The steam curing kettle 48 is shared for both horizontal and vertical steaming, so there is no need to use two different steam curing kettles. It can be understood that two steam curing kettles can also be used, one for horizontal steaming and the other for vertical steaming.

[0062] It should be noted that the flipping direction of the forward flipping is opposite to that of the reverse flipping. Both the semi-finished product flipping table 11 and the finished product flipping table 12 are dual-purpose flipping tables. The specific structure of the dual-purpose flipping table can be the structure in the existing technology, and will not be described in detail here.

[0063] In this embodiment, as Figure 2 As shown, the semi-finished product turnover table 11 and the finished product turnover table 12 are arranged at intervals along a preset direction. A bottom plate transfer device and a steam curing frame transfer device are provided between the semi-finished product turnover table 11 and the finished product turnover table 12. The bottom plate transfer device is used to transfer the bottom plate 62 between the semi-finished product turnover table 11 and the finished product turnover table 12, and the steam curing frame transfer device is used to transfer the steam curing frame 63 between the semi-finished product turnover table 11 and the finished product turnover table 12, so that the bottom plate 62 and the steam curing frame 63 can be recycled, saving costs.

[0064] In this embodiment, as Figure 2 As shown, the base plate transfer device includes a first base plate conveyor line 21 and a second base plate conveyor line 22. The first base plate conveyor line 21 is used to receive and convey the steam-cured base plates 62 and blanks 61. A plate-breaking machine 47 is provided at the first base plate conveyor line 21 to break the blanks 61 on the base plate 62. The second base plate conveyor line 22 is used to convey the empty base plates 62 to the finished product turnover table 12. The setting of two base plate conveyor lines can optimize the operating cycle and improve production efficiency.

[0065] Specifically, the first base plate conveying line 21 and the second base plate conveying line 22 both include two rows of base plate guide wheels arranged in a preset direction and several base plate drive wheels. The base plate is driven to move in the preset direction by the several base plate drive wheels. The structure of the first base plate conveying line 21 and the second base plate conveying line 22 is simple, easy to implement, and low in cost.

[0066] It is understandable that, as an alternative implementation, the base plate transfer device can be an AGV trolley or a roller conveyor, etc.

[0067] In this embodiment, as Figure 2 As shown, the aerated concrete production line also includes a base plate storage silo 23 and a base plate stacking device. The base plate storage silo 23 and the base plate stacking device are located between the semi-finished product turnover table 11 and the finished product turnover table 12. The base plate storage silo 23 is used to store empty base plates 62. The base plate stacking device is used to stack the base plates 62 transferred from the base plate transfer device into the base plate storage silo 23 and to transfer the base plates 62 in the base plate storage silo 23 onto the base plate transfer device. Storing a number of base plates 62 in the base plate storage silo 23 avoids insufficient base plates 62 from affecting the production cycle, resulting in high production efficiency. Specifically, the base plate stacking device is a base plate stacking crane 24, which realizes the transfer of base plates 62. It can be understood that the base plate stacking device can also be a robot, etc.

[0068] In this embodiment, as Figure 2 As shown, the steam curing frame transfer device includes a first steam curing frame conveyor line 31, which is used to receive and transport empty steam curing frames 63 from the finished product turnover table 12. A second bottom plate conveyor line 22 is arranged between the first steam curing frame conveyor line 31 and the first bottom plate conveyor line 21. The arrangement of these three conveyor lines is reasonable and compact, saving floor space.

[0069] In this embodiment, a steam curing cart conveyor line 65 is provided on the side of the first steam curing frame conveyor line 31 away from the second bottom plate conveyor line 22. The steam curing cart 64 is transported through the steam curing cart conveyor line 65, so that the steam curing cart 64 can be recycled.

[0070] In this embodiment, as Figure 2 As shown, the steam curing frame transfer device also includes a second steam curing frame conveyor line 32, which is used to convey empty steam curing frames 63 to the semi-finished product turnover table 11. The first bottom plate conveyor line 21 is located between the second steam curing frame conveyor line 32 and the second bottom plate conveyor line 22. The arrangement of the second steam curing frame conveyor line 32 facilitates cooperation with the semi-finished product turnover table 11, resulting in a more optimized layout.

[0071] It is understandable that, as an alternative implementation, only one steam curing frame conveyor line may be set up.

[0072] Specifically, the first steam curing frame conveyor line 31 and the second steam curing frame conveyor line 32 both include two rows of steam curing frame guide wheels arranged along a preset direction and several steam curing frame drive wheels. The steam curing frames are driven to move along the preset direction by the several steam curing frame drive wheels. The first steam curing frame conveyor line 31 and the second steam curing frame conveyor line 32 have simple structures, save costs, and are easy to implement.

[0073] It should be noted that the layout and length of the bottom plate conveyor line and the steam curing frame conveyor line are not limited to the attached diagram and can be arranged according to specific circumstances.

[0074] It is understandable that, as an alternative implementation, the steam curing frame transfer device can be an AGV trolley or a roller conveyor, etc.

[0075] In this embodiment, as Figure 2As shown, the aerated concrete production line also includes a curing frame storage unit 33 and a curing frame stacking device. The curing frame storage unit 33 and the curing frame stacking device are located between the semi-finished product turning table 11 and the finished product turning table 12. The curing frame storage unit 33 is used to store empty curing frames 63. The curing frame stacking device is used to stack the curing frames 63 transferred from the curing frame transfer device into the curing frame storage unit 33 and to transfer the curing frames 63 in the curing frame storage unit 33 to the curing frame transfer device. Storing a number of curing frames 63 in the curing frame storage unit 33 can prevent insufficient quantity of curing frames 63 from affecting the production cycle and optimize the production cycle. Specifically, the curing frame stacking device is a curing frame stacking crane 34, which realizes the transfer of the curing frames 63. It can be understood that the base plate stacking device can also be a robot, etc.

[0076] It is understood that, as an alternative implementation, the stacking of the steam curing frame 63 and the stacking of the base plate 62 can share a single dual-purpose crane. The dual-purpose crane can realize the transfer of the base plate 62 and the steam curing frame 63, reducing the number of cranes and saving costs.

[0077] It should be noted that the specific structures of dual-purpose cranes, finished product cranes, semi-finished product cranes, steam curing frame stacking cranes, and base plate stacking lifting devices can adopt the structures in existing technologies, and will not be elaborated on here.

[0078] In this embodiment, both the semi-finished product turnover table 11 and the finished product turnover table 12 are equipped with a bottom plate conveying mechanism and a curing frame conveying mechanism. The bottom plate conveying mechanism on the semi-finished product turnover table 11 is correspondingly matched with the first bottom plate conveying line 21, the bottom plate conveying mechanism on the finished product turnover table 12 is correspondingly matched with the second bottom plate conveying line 22, the curing frame conveying mechanism on the semi-finished product turnover table 11 is correspondingly matched with the second curing frame conveying line 32, and the curing frame conveying mechanism on the finished product turnover table 12 is correspondingly matched with the first curing frame conveying line 31. The bottom plate 62 and the curing frame 63 are automatically fed into or out of the turnover table through the bottom plate conveying mechanism and the curing frame conveying mechanism. It can be understood that the bottom plate 62 and the curing frame 63 can also be conveyed to a position parallel to the turnover table, and then the bottom plate 62 and the curing frame 63 can be transferred to the corresponding turnover table using a semi-finished product crane or a finished product crane.

[0079] In this embodiment, the semi-finished product turning table is located in the area where the semi-finished product transfer device is located. The semi-finished product transfer device is used to transfer the cut billets and base plates onto the semi-finished product turning table, transfer the base plates and billets on the semi-finished product turning table onto the steam curing cart, and transfer the steam curing frames and billets on the semi-finished product turning table onto the steam curing cart. Specifically, the semi-finished product transfer device is a semi-finished product crane 41, etc. It can be understood that the semi-finished product transfer device can also be a robot, etc.

[0080] In this embodiment, the finished product turnover table is located in the area where the finished product transfer device is located. The finished product transfer device is used to transfer the bottom plate and billet from the steam curing cart to the bottom plate transfer device, transfer the steam curing frame and billet from the steam curing cart to the finished product turnover table, and transfer the bottom plate and billet on the finished product turnover table to the bottom plate transfer device. Specifically, the finished product transfer device is a finished product crane 42, etc. One end of the first bottom plate conveyor line 21 extends into the finished product crane 42 and is located on one side of the finished product turnover table 12. The finished product crane 42 spans the first bottom plate conveyor line 21 and the steam curing cart conveyor line 65. It can be understood that the finished product transfer device can also be a robot, etc.

[0081] In this embodiment, as Figure 1 and Figure 2 As shown, the aerated concrete production line also includes a raw material area 51, a mixing and pouring area 52, a curing area 53, a cutting area 54, a pre-coating area 55, a steam curing area 56, a post-coating area 57, an unloading area, a single-mold clamping machine 43, a tumbling demolding crane 44, etc. The raw material area 51, curing area 53, pre-coating area 55, steam curing area 56, and post-coating area 57 are arranged longitudinally. The semi-finished product crane 41 and the cutting area 54 are located on one side of the pre-coating area 55, and the finished product crane 42 is located on one side of the post-coating area 57. The semi-finished product crane 41 and the finished product crane 42 are on the same side. The cutting area 54 is set between the tumbling demolding crane 44 and the semi-finished product crane 41. A pre-coating shuttle car 45 is set between the pre-coating area 55 and the curing area, and a post-coating shuttle car 46 is set on the side of the post-coating area 57 away from the steam curing area 56. The pre-coating shuttle car 45 and the post-coating shuttle car 46 are used to transfer the steam curing cars. The preset direction is vertical.

[0082] Specifically, the offline area includes block offline area 58 and plate offline area 59. Block offline area 58 and plate offline area 59 are located on the side of the first bottom plate conveyor line 21 away from the reactor rear area 57. Block offline area 58 and plate offline area 59 share a single mold clamping machine 43.

[0083] The working process of an aerated concrete production line is described below:

[0084] When the production line performs horizontal steaming, the cut blank 61 and base plate 62 (as shown) Figure 3 (As shown) After being transferred by the semi-finished product crane 41 to the semi-finished product turning table 11, the semi-finished product turning table 11 is rotated 90° to remove the bottom skin between the billet 61 and the bottom plate 62. Then the semi-finished product turning table 11 is flipped back, and the bottom plate 62 and the billet 61 are transferred by the semi-finished product crane 41 to the steam curing car 64 (as shown). Figure 4 As shown), after the curing cart 64 is filled with 3 sets of base plates 62 and blanks 61 (as shown), Figure 5 As shown), it enters the steam curing kettle 48 for high-temperature and high-pressure steam curing (as shown). Figure 6 (As shown); After steam curing is completed, the steam curing cart 64, carrying the three-mold billets 61, is parked at the steam curing cart parking position. The finished product crane 42 transfers each bottom plate 62 and the billet 61 on it to the bottom plate and billet placement position. Then, through the first bottom plate conveyor line 21, the billet 61 is split by the plate splitting machine 47. The single mold clamping machine 43 transfers the billet 61 on the bottom plate 62 to the off-line area. Then, the empty bottom plate 62 is sent to the bottom plate stacking crane 24 and bottom plate storage warehouse 23 through the bottom plate cleaning machine 25.

[0085] When the production line is performing vertical steaming, the cut billet 61 and base plate 62 are transferred to the semi-finished product turning table 11 via the semi-finished product crane 41. Simultaneously, the empty curing frame 63 is transferred from the curing frame stacking crane 34 and the curing frame storage warehouse 33 to the semi-finished product turning table 11 via the second curing frame conveyor line 32. After the semi-finished product turning table 11 rotates 90 degrees, the billet 61 is flipped from the base plate 62 into the curing frame 63 (e.g., ...). Figure 7 (As shown), the curing frame 63 and the green body 61 are then transferred to the curing cart 64 by the semi-finished product crane 41 (as shown). Figure 8 As shown), after the curing cart 64 is filled with 3 sets of curing frames 63 and the green body 61 (as shown), Figure 9 As shown), it enters the steam curing kettle 48 for high-temperature and high-pressure steam curing (as shown). Figure 10 (As shown); After steam curing is completed, the steam curing cart 64, carrying the three-mold billets 61, is parked at the steam curing cart parking position. The finished product crane 42 transfers each steam curing frame 63 and the billet 61 on it to the finished product turning table 12. At the same time, the empty bottom plate 62 is conveyed into the finished product turning table 12 via the second bottom plate conveyor line 22. The finished product turning table 12 is rotated 90° to transfer the billet 61 from the steam curing frame 63 to the bottom plate 62. The finished product crane 42 then transfers the bottom plate 62 and the billet 61 to the bottom plate and billet storage position. Then, via the first bottom plate conveyor line 21, the billets are split by the plate splitter 47. The single-mold billet clamping machine 43 transfers the billet 61 on the bottom plate 62 to the off-line area. Then, the empty bottom plate 62 is sent to the bottom plate stacking crane 24 and the bottom plate storage warehouse 23 via the bottom plate cleaning machine 25. Meanwhile, the empty curing frame 63 passes from the finished product turning table 12 through the first curing frame conveyor line 31, and after passing through the curing frame cleaning machine 35, it enters the curing frame stacking crane 34 and the curing frame storage warehouse 33.

[0086] It should be noted that, in Figure 2 In the diagram, the solid arrows indicate the parking position of the curing cart, while the hollow arrows indicate the storage position of the base plate and the billet.

[0087] The present invention also provides a method for producing aerated concrete, using the above-mentioned aerated concrete production line, the method comprising the following steps:

[0088] Horizontal steaming step: The cut blank 61 and base plate 62 are transferred to the semi-finished product turning table 11 by the semi-finished product transfer device; the base plate 62 and blank 61 on the semi-finished product turning table 11 are first rotated 90° forward and then rotated 90° in the opposite direction; the base plate 62 and blank 61 on the semi-finished product turning table 11 are transferred to the steam curing car 64 by the semi-finished product transfer device; the steam curing car 64 is parked at the steam curing car parking position by the finished product transfer device; the base plate 62 and blank 61 on the steam curing car 64 at the steam curing car parking position are transferred out by the finished product transfer device.

[0089] Vertical steaming steps: The cut billet 61 and base plate 62 are transferred to the semi-finished product turning table 11 via the semi-finished product transfer device; the base plate 62 and billet 61 on the semi-finished product turning table 11 are rotated 90° in the forward direction, and the billet 61 is transferred from the base plate 62 to the steaming frame 63; the steaming frame 63 and billet 61 on the semi-finished product turning table 11 are transferred to the steaming cart 64 via the semi-finished product transfer device; the steaming cart 64 after steaming is parked at the steaming cart parking position; the steaming frame 63 and billet 61 on the steaming cart 64 at the steaming cart parking position are transferred to the finished product turning table 12 via the finished product turning table 12; the steaming frame 63 and billet 61 on the finished product turning table 12 are rotated 90° in the forward direction, and the billet 61 is transferred from the steaming frame 63 to the base plate 62; the base plate 62 and billet 61 on the finished product turning table 12 are then transferred out via the finished product turning table 12.

[0090] The above-mentioned aerated concrete production method can achieve simultaneous production using both horizontal and vertical steaming methods by reasonably controlling the semi-finished product turning table 11 and the finished product turning table 12. Furthermore, the production line can produce both blocks and boards, thus achieving multiple uses on a single line and saving production line floor space and costs.

[0091] In this embodiment, between the steps of transferring the bottom plate 62 and the billet 61 on the semi-finished product turning table 11 to the steam curing cart 64 by the semi-finished product transfer device and the step of parking the steam curing cart 64 at the steam curing cart parking position, the horizontal steaming step further includes: controlling the steam curing cart 64 and the bottom plate 62 and the billet 61 on it to enter the steam curing kettle 48 so as to steam curing the billet 61.

[0092] Between the steps of transferring the curing frame 63 and the billet 61 on the semi-finished product turning table 11 to the curing cart 64 by the semi-finished product transfer device and the step of parking the curing cart 64 at the curing cart parking position, the vertical steaming step also includes: controlling the curing cart 64 and the curing frame 63 and the billet 61 on it to enter the curing kettle 48 to cure the billet 61.

[0093] In this embodiment, before the step of rotating the steaming frame 63 and the blank 61 90° forward on the finished product turning table 12, the vertical steaming step further includes: conveying an empty bottom plate 62 onto the finished product turning table 12 via a bottom plate transfer device. In the step of transferring the bottom plate 62 and the blank 61 out via the finished product transfer device, the bottom plate 62 and the blank 61 are transferred to the bottom plate transfer device via the finished product transfer device. The bottom plate 62 is transferred between the semi-finished product turning table 11 and the finished product turning table 12 via the bottom plate transfer device, thereby allowing the bottom plate 62 to be recycled and saving costs.

[0094] Specifically, in the step of transferring the base plate 62 and the billet 61 to the base plate transfer device via the finished product transfer device, the base plate 62 and the billet 61 are transferred to the first base plate conveyor line 21. The empty base plate is then conveyed to the finished product turnover table 12 via the second base plate conveyor line 22. The arrangement of two base plate conveyor lines between the semi-finished product turnover table 11 and the finished product turnover table 12 optimizes the operating cycle and improves production efficiency.

[0095] After the step of rotating the curing frame 63 and the blank 61 90° forward on the finished product turning table 12, the vertical steaming step further includes: rotating the empty curing frame 63 90° backward on the finished product turning table 12; and transferring the empty curing frame 63 on the finished product turning table 12 to the curing frame transfer device. The curing frame transfer device transfers the curing frame 63 between the semi-finished product turning table 11 and the finished product turning table 12, thereby enabling the curing frame 63 to be recycled and saving costs.

[0096] In this embodiment, after the step of transferring the base plate 62 and the billet 61 to the base plate transfer device via the finished product transfer device, both the horizontal steaming step and the vertical steaming step further include: conveying the empty base plate 62 on the base plate transfer device to the location of the base plate stacking device; and stacking the empty base plate 62 on the base plate transfer device into the base plate storage warehouse 23 via the base plate stacking device. Specifically, the empty base plate 62 on the first base plate conveyor line 21 is conveyed to the location of the base plate stacking device; the base plate stacking device stacks the empty base plate 62 on the first base plate conveyor line 21 into the base plate storage warehouse 23. The base plate storage warehouse 23 stores a number of base plates 62, which can avoid the production cycle being affected by too few base plates 62, and the production efficiency is high.

[0097] In this embodiment, after the step of transferring the empty curing frames 63 on the finished product turnover table 12 to the curing frame transfer device, the vertical steaming step further includes: conveying the empty curing frames 63 on the curing frame transfer device to the location of the curing frame stacking device; and stacking the empty curing frames 63 on the curing frame transfer device into the curing frame storage warehousing 33 by the curing frame stacking device. Specifically, the empty curing frames 63 on the finished product turnover table 12 are transferred to the first curing frame conveyor line 31; the empty curing frames 63 on the first curing frame conveyor line 31 are conveyed to the location of the curing frame stacking device; and the curing frame stacking device stacks the empty curing frames 63 on the first curing frame conveyor line 31 into the curing frame storage warehousing 33. The curing frame storage warehousing 33 stores a number of curing frames 63, which can avoid the production cycle being affected by too few curing frames 63 and optimize the production cycle.

[0098] Specifically, the second curing frame conveyor line 32 transports the empty curing frames 63 to the semi-finished product turnover table 11. The second curing frame conveyor line 32 is designed to work seamlessly with the semi-finished product turnover table 11, resulting in a more optimized layout.

[0099] Specifically, the cut billet 61 and base plate 62 are transferred to the semi-finished product turning table by the semi-finished product transfer device; the base plate 62 and billet 61 on the semi-finished product turning table 11 are transferred to the steam curing car 64 by the semi-finished product transfer device; the steam curing frame 63 and billet 61 on the semi-finished product turning table 11 are transferred to the steam curing car 64 by the semi-finished product transfer device; the base plate 62 and billet 61 are transferred to the first base plate conveyor line 21 by the finished product transfer device; and the steam curing frame 63 and billet 61 on the steam curing car 64 are transferred to the finished product turning table 12 by the finished product transfer device.

[0100] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0101] 1. The ALC production line for horizontal and vertical steaming includes a raw material area 51, a mixing and casting area 52, a curing area 53, a cutting area 54, a pre-coat area 55, a post-coat area 57, a steam curing area 56, an off-line area, and a transfer device. Two turning tables are arranged on the production line, used for 90° turning of the semi-finished billet and the finished product, respectively. The semi-finished billet turning table 11 is located after the "cutting" step in the production process, on both sides of the end of the cutting line. The semi-finished billet 61 is transferred via a semi-finished product crane 41 and other semi-finished product transfer devices. After the cutting equipment cuts the billet 61 into a semi-finished billet, the semi-finished billet is transferred to the semi-finished billet turning table 11 for turning, and then transferred to the steam curing cart 64 after turning. The finished product turnover table 12 is located between the "steam curing" and "splitting" processes, in the area of ​​the finished product crane 42. Finished products and steam curing frames 63 are transferred from the steam curing cart 64 to the finished product turnover table 12 via the finished product crane 42 and other finished product transfer devices. Then, the finished product and base plate 62 are transferred to the first base plate conveyor line 21, where they enter the splitting machine 47 for splitting. By rationally controlling the semi-finished product turnover table 11 and the finished product turnover table 12, simultaneous horizontal and vertical steaming production is achieved, enabling dual-purpose production lines and saving production line space and costs.

[0102] 2. Between the semi-finished product turnover table 11 and the finished product turnover table 12, there are two bottom plate conveying lines, two steam curing frame conveying lines, a steam curing frame stacking crane 34, a steam curing frame storage box 33, a bottom plate stacking crane 24, and a bottom plate storage box 23. Through the conveying lines and stacking cranes, the steam curing frame 63 and the bottom plate 62 can be transferred between the semi-finished product turnover table 11 and the finished product turnover table 12, which can optimize the operating cycle and improve production efficiency.

[0103] 3. When performing horizontal and vertical steaming production on the production line, the same steam curing kettle 48 of the same size is used. The old production line can be upgraded. For example, the production line can use a mold car with a length of 6 meters × height of 1.2 meters × width of 0.6 meters. The diameter of the steam curing kettle 48 is 2.68 meters.

[0104] 4. Compared with the horizontal steaming process, the vertical steaming process shortens the steaming time of the blocks, reduces the adhesion between the boards, and reduces the breakage of the boards when they break apart.

[0105] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
