Description

Technical Field

[0001] This utility model relates to the field of autoclave technology, specifically to an autoclave for autoclaved aerated concrete blocks. Background Technology

[0002] In the production process of autoclaved aerated concrete (AAC) blocks, the steam curing process is a key step to ensure the quality of the blocks. The steam curing kettle, as the core equipment in this process, directly determines the quality of the block products. However, the existing autoclaved aerated concrete (AAC) block steam curing kettles on the market still have some problems in practical applications.

[0003] Regarding steam distribution, the steam supply system design of some steam curing kettles is not scientific enough, making it difficult to achieve uniform distribution of steam within the kettle. This results in inconsistent heating of blocks at different locations within the kettle. Some blocks may be under-cured due to insufficient steam supply, affecting their strength and performance; while other blocks may be over-cured due to excessive steam concentration, leading to resource waste or even block damage. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an autoclaved aerated concrete block curing autoclave to solve the problems mentioned in the background art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figures 1 to 3 As shown, this utility model provides an autoclaved aerated concrete block autoclave, including an autoclave body 1, a moving track 15 installed inside the autoclave body 1, the moving track 15 is used to carry the autoclave cart, the autoclave cart is used to place concrete blocks, and the concrete blocks are transported to the interior of the autoclave body 1 through the moving track 15.

[0029] Steam distributors 14 are installed at both the upper and lower ends of the moving track 15 inside the steam curing kettle body 1. A steam supply main pipe 12 is also provided on one side of the steam curing kettle body 1. One end of the steam supply main pipe 12 is connected to a steam supply branch pipe 13. The steam supply branch pipe 13 has two output ends. These two output ends pass through the upper and lower ends of the steam curing kettle body 1 and are connected to the internal steam distributors 14. The steam distributor 14 has a cavity inside. The steam in the steam supply main pipe 12 can be delivered to the cavity of the steam distributor 14 through the steam supply branch pipe 13.

[0030] Preferably, the steam distributor 14 in this embodiment adopts a design with a planar structure on one side and an arc-shaped structure on the other side. The arc-shaped structures of both steam distributors 14 face the side closer to the moving track 15, and multiple steam discharge holes are evenly opened on the arc surface of the steam distributor 14. The steam in the steam distributor 14 can be sprayed out at multiple angles along the steam discharge holes at the same time, so that the steam can be more evenly distributed into the steam curing tank body 1, so that the concrete blocks on the steam curing vehicle can fully contact the steam and improve the steam curing effect.

[0031] Specifically, a material inlet / outlet is provided on one side of the autoclave body 1 for the autoclave cart to enter and exit. A support plate 5 is hinged to the outer wall of the material inlet / outlet. A threaded hole is provided in the middle of the support plate 5, and a limiting threaded rod 3 is threadedly connected to the threaded hole of the support plate 5. One end of the limiting threaded rod 3 passes through the support plate 5 and is connected to a sealing door 2. The sealing door 2 matches the shape of the material inlet / outlet and can seal it. A handwheel 4 is installed on the other end of the limiting threaded rod 3. When it is necessary to transport concrete blocks into the autoclave body 1, the operator rotates the limiting threaded rod 3 by using the handwheel 4. The limiting threaded rod 3 will move the sealing door 2 away from the material inlet / outlet. The material inlet and outlet are opened by rotating the support plate 5. Since the support plate 5 is hinged to the steam curing vessel body 1, the support plate 5 will drive the sealing door 2 to rotate around the steam curing vessel body 1, thereby opening the material inlet and outlet for concrete blocks to enter and exit. When the concrete blocks need to be steam cured, the operator first rotates the support plate 5, which will drive the sealing door 2 to rotate around the steam curing vessel body 1, so that the sealing door 2 rotates to be parallel to the material inlet and outlet of the steam curing vessel body 1. Then, the operator rotates the limiting threaded rod 3 by turning the handwheel 4. The limiting threaded rod 3 will drive the sealing door 2 to move horizontally and fit tightly with the material inlet and outlet, thereby sealing the material inlet and outlet.

[0032] Preferably, the edge of the material inlet and outlet in this embodiment adopts a stepped structure, and the sealing door 2 matches the stepped structure. The sealing door 2 can fit tightly with the material inlet and outlet, thereby improving the sealing effect.

[0033] More specifically, in this embodiment, the steam incubator body 1 is equipped with a fixing hook 7 and a fixing frame 18 on the two side walls of the material inlet and outlet respectively. The two sides of the support plate 5 are respectively hinged with hinge plates 6. One of the hinge plates 6 is provided with a hook that matches the fixing hook 7. The hook and the fixing hook 7 are detachably connected. The other hinge plate 6 passes through the fixing frame 18 and is welded with a limiting plate 17. The limiting plate 17 is engaged with the fixing frame 18, thereby fixing one end of the hinge plate 6 to the fixing frame 18 and preventing the hinge plate 6 from coming out of the fixing frame 18. When the material inlet and outlet need to be closed, the sealing door 2 is first driven to fit tightly against the material inlet and outlet. Then, the hook of the hinge plate 6 is connected to the fixing hook 7 to position the sealing door 2 and further enhance the stability of the sealing door 2.

[0034] Preferably, the side wall of the steam curing vessel body 1 in this embodiment is provided with a cavity interlayer, which is filled with heat insulation material 16. The heat insulation material 16 can be aluminum silicate fiber felt, aluminum silicate board, asbestos felt or magnesium silicate insulation board, etc., which can effectively reduce heat loss during steam curing and improve energy utilization efficiency.

[0035] A pressure gauge 10 is installed on the outside of the steam curing vessel body 1. The pressure gauge 10 can monitor the steam pressure inside the steam curing vessel body 1 in real time. At the same time, an exhaust pipe 11 is installed on the left side of the steam curing vessel body 1. An exhaust valve is installed on the exhaust pipe 11. When the steam pressure inside the steam curing vessel body 1 is too high, the exhaust valve can be opened to release some steam and adjust the pressure inside the steam curing vessel body 1. Drainage holes are also opened on both sides of the bottom of the steam curing vessel body 1. The drainage holes are connected to the wastewater discharge pipe 8. The wastewater generated during the steam curing process can be discharged in a timely manner through the wastewater discharge pipe 8.

[0036] Support bases 9 are also fixedly installed on both sides of the bottom of the steam curing vessel body 1 to ensure the stability of the steam curing vessel body 1.

[0037] Working principle and usage process of this utility model:

[0038] When using this autoclaved aerated concrete block curing autoclave, the concrete blocks are first placed on the curing cart and transported to the interior of the autoclave body 1 via the moving track 15. Then, the support plate 5 is rotated, which will cause the sealing door 2 to rotate around the autoclave body 1, making the sealing door 2 parallel to the material inlet and outlet of the autoclave body 1. Then, the limit threaded rod 3 is rotated by handwheel, which will cause the sealing door 2 to move horizontally until it is tightly fitted with the material inlet and outlet. Finally, the hook of the hinge plate 6 is fixed on the fixing hook 7, thereby fixing the sealing door 2, enhancing the sealing performance and stability of the sealing door 2 during the curing process, and preventing steam leakage.

[0039] Then, the steam supply main pipe 12 supplies steam to the steam distributor 14 through the steam supply branch pipe 13, and then sprays it evenly into the steam curing tank body 1 through the steam discharge hole on the steam distributor 14, so that the concrete blocks are fully steam cured. At the same time, during the steam curing process, the internal steam pressure of the steam curing tank body 1 can be viewed through the pressure gauge 10, and the steam pressure can be adjusted in time to ensure that the steam curing process is carried out under a suitable pressure. After the steam curing is completed, the wastewater discharge pipe 8 is opened to discharge the wastewater, and the sealed door 2 is opened to take out the steam cured concrete blocks.

[0040] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
