Description

Technical Field

[0001] This utility model relates to the field of autoclaved fly ash brick curing technology, and more specifically, to a steam curing device for autoclaved fly ash brick production. Background Technology

[0002] Autoclaved fly ash bricks are made primarily from fly ash, lime, or cement, with the addition of appropriate amounts of gypsum and aggregates. The mixture is prepared, pressed into shape, and cured under high pressure, normal pressure, or naturally. Specifically, they are made from fly ash and lime as the main raw materials, with the addition of appropriate amounts of gypsum and aggregates, prepared as raw materials, pressed into shape, and cured under high pressure with steam. Autoclaved fly ash bricks require autoclaving during production.

[0003] A search revealed that patent application CN201911274441.X discloses an autoclaving device for fly ash brick production, comprising a base, a housing, a curing chamber, a door, and a pressure relief box. The housing and curing chamber are bolted to the top of the base, with the housing located on one side of the curing chamber. The door is hinged to the surface of the curing chamber, and the pressure relief box is welded to the top of the curing chamber. This application uses a pressure relief valve inside the pressure relief box to guide gas into the chamber. A condensing plate, clipped to the top of the guide plate, reduces the temperature of the high-temperature steam, causing it to condense into water droplets. These droplets are then guided through the guide plate to a water storage tank, from which they are discharged into the steam generator, thus recycling water resources and preventing waste, achieving energy savings. However, it still has the following drawbacks:

[0004] (1) In the prior art, the steam curing device places fly ash bricks on the trolley for steam curing. After the steam curing of fly ash bricks is completed, they are taken out and then new fly ash bricks are placed on the trolley to perform steam curing on the subsequent fly ash bricks. During this period, the curing device no longer works, the steam curing of fly ash bricks is interrupted, resulting in low efficiency of steam curing.

[0005] (2) The existing curing device requires manual placement of the drag rack into the curing box. Since the drag rack with fly ash bricks is heavy, it is not easy to drag manually and its practicality is poor.

[0006] Therefore, we have made improvements to this and proposed a steam curing device for the production of autoclaved fly ash bricks. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment proposes a steam curing device for autoclaved fly ash brick production, including a base frame 1. Two slide rails 2 are symmetrically and fixedly connected to the upper surface of the base frame 1. Sliding blocks 3 are slidably connected to both ends of the two slide rails 2. Moving plates 4 are fixedly connected to the upper surfaces of adjacent sliding blocks 3. A traveling mechanism 5 is provided on the moving plates 4. A fixed frame 6 is fixedly connected to the upper surface of the moving plates 4. A bearing plate 7 is fixedly connected to the upper surface of the fixed frame 6. A set of brick frames 8 are stacked on the upper surface of the bearing plates 7. A curing cover 9 is fixedly connected to the center of the upper surface of the base frame 1. An opening and closing mechanism 10 is provided on the curing cover 9. A set of brick frames 8 are evenly fixedly connected inside the curing cover 9. Steam pipe 11, with connecting pipe 12 fixedly connected to the rear side of each steam pipe 11. The outer end of the connecting pipe 12 passes through the curing hood 9 and is fixedly connected to the steam inlet pipe 13. The moving plate 4 is driven by the walking mechanism 5 to move on the slide rail 2, which drives the brick frame 8 on the bearing plate 7 to enter and exit the curing hood 9. The curing hood 9 opens and closes the gate 1001 through the opening and closing mechanism 10. Steam enters from the steam inlet pipe 13 and is distributed to each steam pipe 11 through the connecting pipe 12 to steam cure the autoclaved fly ash bricks in the brick frame 8 inside the curing hood 9. Fly ash bricks to be cured can be placed on the brick frame 8. At the same time, a forklift is used to stack and unload the brick frame 8 to improve the efficiency of curing.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, the walking mechanism 5 further includes a rack 501 fixed on the inner side wall of the bottom frame 1, a first motor 502 fixedly connected to the upper end face of the moving plate 4, the driving end of the first motor 502 passing through the moving plate 4 and fixedly connected to a connecting shaft 503, and a gear 504 meshing with the rack 501 fixedly connected to the connecting shaft 503; when the first motor 502 starts, it drives the connecting shaft 503 to rotate, thereby driving the gear 504 to rotate. Since the gear 504 meshes with the rack 501, the moving plate 4 moves on the slide rail 2, realizing the operation of the brick frame 8 entering and exiting the curing cover 9, and automating the feeding and discharging of materials.

[0032] like Figure 1 and Figure 2As shown, in a preferred embodiment, based on the above method, the opening and closing mechanism 10 further includes baffles 1001 respectively disposed on the left and right sides of the curing cover 9. A bracket 1002 is fixedly connected to the upper end face of the curing cover 9. Two threaded rods 1003 are symmetrically and rotatably connected between the bracket 1002 and the curing cover 9. Two second motors 1004 are symmetrically and fixedly connected to the upper end face of the curing cover 9. The driving ends of the two second motors 1004 penetrate the top wall of the bracket 1002 and are connected to the top ends of the threaded rods 1003. The bracket 1002 is fixedly connected, with strip-shaped openings on both the left and right side walls, and an adjusting block 1005 is matched in the strip-shaped opening. The inner end of the adjusting block 1005 is threadedly connected to the threaded rod 1003, and the outer end of the adjusting block 1005 is fixedly connected to the stop door 1001. When the second motor 1004 is started, it drives the threaded rod 1003 to rotate. The rotation of the threaded rod 1003 causes the adjusting block 1005 to move up and down, thereby driving the stop door 1001 to move up and down, realizing the opening and closing of the stop door 1001 of the maintenance cover 9.

[0033] like Figure 1 As shown, in a preferred embodiment, based on the above method, further, the outer ends of both ends of the upper surface of the bottom frame 1 are fixedly connected to limit blocks 14, and the upper surface of the limit block 14 is at the same horizontal plane as the upper surface of the slider 3; the limit block 14 plays a limiting role to prevent the moving plate 4 from moving excessively and falling off the slide rail 2.

[0034] like Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, the upper surface of the brick frame 8 is symmetrically and fixedly connected with two stacking plates 15, and a first reinforcing block 16 is uniformly fixedly connected inside the stacking plate 15. The stacking plate 15 is used to provide support and positioning when the brick frame 8 is stacked, so that the brick frame 8 can be stacked neatly. The first reinforcing block 16 enhances the structural strength of the stacking plate 15, prevents the stacking plate 15 from deforming or being damaged due to excessive force during the stacking process, and ensures the reliability of the stacking of the brick frame 8.

[0035] like Figure 1 and Figure 6 As shown, in a preferred embodiment, based on the above method, a set of second reinforcing blocks 17 are fixedly connected at equal intervals at both ends of the bottom frame 1, and through holes are opened at equal intervals on the bearing surface of the brick frame 8. The second reinforcing blocks 17 are used to enhance the structural strength of the bottom frame 1, so that it can withstand the weight of components such as the moving plate 4, the fixed frame 6, the bearing plate 7 and the brick frame 8, as well as various forces during operation, to ensure the stability of the overall structure of the device. During the steam curing process, steam can penetrate evenly into the autoclaved fly ash bricks in the brick frame 8 through these through holes, improving the effect and quality of steam curing, making the bricks heat evenly and curing more thoroughly.

[0036] Specifically, in use of this steam curing device for autoclaved fly ash brick production: fly ash bricks are placed in the left brick frame 8, and then a forklift is used to stack the brick frames 8 onto the support plate 7. After stacking, the first motor 502 drives the connecting shaft 503 to rotate, which in turn drives the gear 504 to rotate. Since the gear 504 meshes with the rack 501, the moving plate 4 moves on the slide rail 2, allowing the support plate 7 on the left and the fly ash bricks above it to enter the curing hood 9. Then, the second motor 1004 on the left drives the threaded rod 1003 to rotate. The rotation of the threaded rod 1003 causes the adjusting block 1005 to move downward, thereby... The moving damper 1001 moves downward and closes, allowing steam to enter through the steam inlet pipe 13 and be distributed to each steam pipe 11 via the connecting pipe 12. This steam curing process is applied to the autoclaved fly ash bricks in the brick frame 8 within the curing hood 9. During steam curing, the next batch of fly ash to be cured is transferred to the brick frame 8 and stacked on the right-side bearing plate 7. Once the fly ash in the curing hood 9 has finished steam curing, the left damper 1001 is opened to remove the cured bricks. Then, the left damper 1001 closes and the right damper 1001 begins to move the fly ash bricks from the right side into the curing hood 9 for steam curing. This process ensures greater continuity and improves curing efficiency.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
