Description

Technical Field

[0001] This utility model relates to the technical field of gas distribution devices, specifically a carbon dioxide gas distribution device for concrete curing. Background Technology

[0002] A carbon dioxide gas distribution device for concrete curing is a device used in the concrete curing process to improve curing efficiency and quality by rationally distributing carbon dioxide gas. Its main function is to uniformly deliver carbon dioxide gas into the curing environment, so that the concrete can fully absorb carbon dioxide during the curing process, thereby accelerating the carbonation reaction and improving the strength and durability of the concrete. The carbon dioxide gas distribution device for concrete curing is usually inserted deep into the carbonation curing box to release gas into the curing box. At the same time, it needs to be stirred to promote the carbonation process. This design can ensure that the carbon dioxide gas can be evenly distributed and fully react with the calcium and magnesium components in the concrete, thereby improving the strength and durability of the concrete. In concrete curing, carbon dioxide gas distribution devices are typically inserted deep into the carbonation curing chamber to ensure that carbon dioxide gas can directly act on the concrete. To improve the uniformity of carbon dioxide distribution within the curing chamber, mixing is usually performed. However, this method has certain problems: when carbon dioxide is discharged from the distribution device, the impact of the concrete during mixing causes small concrete particles to splash and enter the distribution device. Once these small concrete particles enter the distribution device, they adhere to the inner wall of the pipes. Over time, these adhered concrete particles gradually accumulate, eventually causing pipe blockage, thus affecting the normal flow of carbon dioxide gas and reducing the curing effect. Therefore, a carbon dioxide gas distribution device for concrete curing is proposed to address the above problems. Utility Model Content

The central cylinder 51 and the extension plate 53 are integrally fixed structures. Air channels 54 are opened on the inner side of both the central cylinder 51 and the extension plate 53. The stirring and air distribution assembly 6 includes an air distribution rod 61. The bottom end of the air distribution rod 61 is fixedly connected to the base plate 62 by bolts.

The shaft rotation hole 32 is rotatably connected to the central cylinder 51. The inner side of the shaft rotation hole 32 is sealed to the central cylinder 51 by a sealing ring. The top of the cover plate body 31 is fixedly connected to the housing of the drive motor 33. A first gear 34 is fixedly connected to the outer side of the main shaft of the drive motor 33. The outer side of the first gear 34 meshes with the outer side of the second gear 52. The top of the cover plate body 31 is fixedly connected to the support frame 2. A gap is provided between the cover plate body 31 and the gas conveying pipe 1. The gas conveying pipe 1 is sleeved on the outer side of the central cylinder 51. The inner side of the gas conveying pipe 1 is in contact with the outer side of the central cylinder 51 by a sealing ring. With the above arrangement, the passive rotating component 5 and the mixing and gas distribution component 6 can be driven to rotate as a whole, so as to achieve the effect of mixing concrete inside the carbonation curing box body 41. At the same time, the seal between the cover plate body 31 and the central cylinder 51 can prevent carbon dioxide from flowing out of the carbonation curing box body 41. As a further implementation of this solution, the carbonization curing box assembly 4 includes a carbonization curing box body 41. A gear ring 42 is fixedly connected to the upper part of the carbonization curing box body 41. The inner side of the gear ring 42 meshes with the outer side of the third gear 67. The carbonization curing box body 41 is fixedly connected to the cover plate body 31. The carbonization curing box body 41 is sealed with the cover plate body 31 by a rubber gasket. Through the above-mentioned arrangement, the detachable fixing method between the cover plate body 31 and the carbonization curing box body 41 allows concrete to be poured into the interior of the carbonization curing box body 41. The meshing design can control the rotation of the spiral blade 64. The fixed connection between the carbonization curing box body 41 and the cover plate body 31, as well as the sealing of the rubber gasket, further enhance the structural stability and sealing performance of the device, ensuring the uniform distribution and normal flow of carbon dioxide gas inside the carbonization curing box body 41. As a further implementation of this scheme, the gas channel 54 is connected to the inside of the gas delivery pipeline 1. A fixing port is opened in the gas channel 54 near the gas distribution rod 61. The fixing port of the gas channel 54 is fixedly connected to the gas distribution rod 61. Through the above settings, carbon dioxide gas can be smoothly delivered from the gas delivery pipeline 1 to the inside of the gas distribution rod 61, ensuring the smoothness and stability of gas delivery. As a further implementation of this scheme, the air distribution rod 61 has a through hole at one end near the air channel 54. The flow channel 66 is connected to the air channel 54 through the through hole of the air distribution rod 61. The upper end of the base plate 62 is sealed to the air distribution rod 61 by a rubber gasket. The upper end of the rotating rod 63 is rotatably connected to the upper end of the air distribution rod 61. The upper end of the air distribution rod 61 is sealed to the upper end of the rotating rod 63 by a rubber ring. The air distribution rod 61 has a through hole near the rubber duckbill valve 65. The outer side of the spiral blade 64 is clearance-fitted with the inner side of the flow channel 66. The rubber duckbill valve 65 is embedded inside the air distribution rod 61. Through the above settings, the self-cleaning of the flow channel 66 is achieved, preventing concrete particles from accumulating on the inner wall of the flow channel 66 and causing blockage, thereby improving the anti-blocking capability and operating efficiency of the device.

[0018] Workflow: During installation, concrete is poured into the interior of the carbonation curing box body 41. At this time, the cover plate assembly 3 and the passive rotating assembly 5 are combined. The passive rotating assembly 5 is inserted into the interior of the carbonation curing box body 41. After the bottom end of the cover plate body 31 is aligned with the top end of the carbonation curing box body 41, the cover plate body 31 is fixed to the carbonation curing box body 41 with bolts. Then, the gas delivery pipe 1 is aligned with the central cylinder 51 and inserted into the outside of the central cylinder 51. The support frame 2 is fixed to the cover plate body 31 with bolts. The external carbon dioxide delivery pipe is connected to the gas delivery pipe 1 to complete the installation. When carbon dioxide gas is distributed into the interior of the carbonation curing chamber body 41, the gas delivery pipe 1 is connected to the external carbon dioxide gas delivery pipe 1. The carbon dioxide gas is delivered to the interior of the central cylinder 51 through the gas delivery pipe 1, and then to the flow channel 66 opened in the air distribution rod 61 through the gas channel 54. At this time, the flow channel 66 generates a certain gas pressure expansion. Under the action of gas pressure, the gas flows out through the rubber duckbill valve 65, thereby delivering carbon dioxide into the interior of the carbonation curing chamber body 41. At the same time, the drive motor 33 is started, and the drive motor 33 drives the first gear 34 to rotate. The first gear 34 drives the central cylinder 51 to rotate through the meshing extension plate 53. The central cylinder 51 is connected to the interior of the cover plate body 31. The central cylinder 51 drives the extension plate 53 and the two mixing and air distribution components 6 to rotate as a whole. Since the drive motor 33 controls the two mixing and air distribution components 6 to be opposite to the concrete impact direction, This design prevents excessive pressure from the concrete on the rubber duckbill valve 65 during rotation, significantly reducing the risk of concrete entering the flow channel 66. It also improves the uniformity of carbon dioxide mixing with the concrete. When the two mixing and air distribution components 6 rotate, the third gear 67 meshes with the gear ring 42, causing the rotating rod 63 and the spiral blade 64 to rotate rapidly. This rapid rotation causes the rotating rod 63 and the spiral blade 64 to cause the concrete to fall onto the inner wall of the flow channel 66 through centrifugal force. Even if concrete enters the flow channel 66 from the rubber duckbill valve 65, the spiral blade 64 scrapes and conveys the concrete downwards from the inner wall of the flow channel 66, before it is discharged through the rubber duckbill valve 65, preventing concrete from adhering to the inner wall of the flow channel 66. The base plate 62 is fixed to the air distribution rod 61, allowing for disassembly of the base plate 62 and maintenance of the internal structure of the air distribution rod 61. Based on the above principles, the device can evenly distribute carbon dioxide into the interior of the carbonation curing chamber 41. During mixing, it can significantly reduce the amount of carbon dioxide entering the gas distribution device due to the impact of concrete. At the same time, the device can self-clean the concrete from the inside of the gas distribution device, significantly reducing the phenomenon of pipe blockage affecting the normal flow of carbon dioxide gas and improving the curing effect.
