Description

Technical Field

[0001] This utility model relates to a high-efficiency steam curing device for precast components. Background Technology

[0002] Existing technologies for steam curing precast components involve placing them in relatively large, enclosed chambers and introducing hot steam into them. However, these enclosed chambers are typically designed in a simple manner, with several shelves for layering the components before steam is introduced. This structural approach results in low curing efficiency and uneven curing of the components. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a high-efficiency steam curing device for precast components.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a high-efficiency precast component steam curing device, including a main body and a steam generator, wherein the main body and the steam generator are connected by a gas pipe, and the gas pipe includes an upper gas pipe and a lower gas pipe;

[0005] The main body is provided with an upper air outlet mechanism, a lower air outlet mechanism and a support mechanism. The steam generator is connected to the upper air outlet mechanism through an upper air pipe and to the lower air outlet mechanism through a lower air pipe.

[0006] The upper air outlet mechanism includes three air outlet units. Each air outlet unit includes an air outlet plate and a rotary joint. The air outlet plate is circular. The center of the upper end face of the air outlet plate is connected to the upper air pipe through the rotary joint. The center of the lower end face of the air outlet plate is provided with a main air outlet hole. A filter screen is provided inside the main air outlet hole. Several guide holes are provided on the side of the air outlet plate. The axis of the guide holes is perpendicular to the diameter of the air outlet plate. The lower air outlet mechanism includes a horizontal pipe and a vertical pipe. The horizontal pipe is horizontally arranged at the bottom of the main body. The middle part of the horizontal pipe is connected to the steam generator through the lower air pipe. There are several vertical pipes. Each vertical pipe is arranged vertically and is close to the interior of the main body. Several through holes are provided on the vertical pipe. The upper end of the vertical pipe is sealed. The lower end of the vertical pipe is connected to the end of the horizontal pipe. Several steam holes are provided on the wall of the horizontal pipe.

[0007] The support mechanism includes several support units, which are evenly arranged from top to bottom. Each support unit includes a support net and two connecting blocks. The two connecting blocks are respectively located at both ends of the support net. One end of the connecting block is connected to the support net, and the other end of the connecting block is connected to the inner wall of the main body.

[0009] Preferably, the support net includes several semi-cylindrical net columns arranged side by side, the radial cross-section of the net columns is a semi-circular ring, and the semi-circular ring cross-sections of each net column are connected end to end.

[0010] Preferably, the main vent is provided with several secondary vents around its periphery.

[0011] The beneficial effects of this utility model are that, after steam is introduced into the steam outlet plate, the steam outlet plate can rotate and release steam with the help of the guide holes, which improves the uniformity and range of steam release. In addition, with the steam release of the horizontal and vertical pipes, all-round steam curing can be achieved. The support net can not only provide stable support for the precast components, but also increase the air permeability, which can not only improve the curing effect, but also improve the curing efficiency.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] like Figure 1-2 As shown, a high-efficiency precast component steam curing device includes a main body 1 and a steam generator 2. The main body 1 and the steam generator 2 are connected by an air pipe, which includes an upper air pipe 3 and a lower air pipe 4.

[0019] The main body 1 is provided with an upper air outlet mechanism, a lower air outlet mechanism and a support mechanism. The steam generator 2 is connected to the upper air outlet mechanism through an upper air pipe 3 and to the lower air outlet mechanism through a lower air pipe 4.

[0020] The upper air outlet mechanism includes three air outlet units. Each air outlet unit includes an air outlet plate 5 and a rotary joint 6. The air outlet plate 5 is circular. The center of the upper end face of the air outlet plate 5 is connected to the upper air pipe 3 through the rotary joint 6. The center of the lower end face of the air outlet plate 5 is provided with a main air outlet hole 5-1. A filter screen is provided inside the main air outlet hole 5-1. Several guide holes are provided on the side of the air outlet plate 5. The axis of the guide holes is perpendicular to the diameter of the air outlet plate 5. The lower air outlet mechanism includes a horizontal pipe 7 and a vertical pipe 8. The horizontal pipe 7 is horizontally arranged at the bottom of the main body 1. The middle part of the horizontal pipe 7 is connected to the steam generator 2 through the lower air pipe 4. There are several vertical pipes 8, each vertically arranged. The vertical pipes 8 are arranged close to the interior of the main body 1. Several through holes are provided on the vertical pipes 8. The upper end of the vertical pipes 8 is sealed. The lower end of the vertical pipes 8 is connected to the end of the horizontal pipe 7. Several steam holes are provided on the pipe wall of the horizontal pipe 7.

[0021] The support mechanism includes several support units, which are evenly arranged from top to bottom. Each support unit includes a support net 10 and two connecting blocks 9. The two connecting blocks 9 are respectively located at both ends of the support net 10. One end of the connecting block 9 is connected to the support net 10, and the other end of the connecting block 9 is connected to the inner wall of the main body 1.

[0022] Preferably, the vertical pipe 8 passes through the connecting block 9.

[0023] Preferably, the support net 10 includes a plurality of semi-cylindrical net posts 11 arranged side by side, the radial cross section of the net post 11 being a semi-circular ring, and the semi-circular ring cross sections of each net post 11 being connected end to end.

[0024] Preferably, the main vent 5-1 is provided with a number of secondary vents 5-2 around its periphery.

[0025] Steam generator 2 mainly produces steam, which is introduced into the main body 1 through the upper air pipe 3 and the lower air pipe 4 respectively.

[0026] When the steam in the upper steam pipe 3 enters the steam outlet plate 5 through the rotary joint 6, some of the steam will be discharged from the main steam outlet 5-1 and the auxiliary steam outlet 5-2 on the lower end face of the steam outlet plate 5, while the other part will be discharged from the guide hole. When the steam is discharged from the guide hole, under the action of the reaction force, it pushes the steam outlet plate 5 to rotate in the opposite direction, thereby realizing rotary steam discharge, increasing the steam falling area, and cooperating with the rotary steam spraying out of the main steam outlet 5-1 and the auxiliary steam outlet 5-2, thereby improving the uniformity of steam discharge. The steam entering from the lower steam pipe 4 Steam is discharged from the horizontal pipe 7 and the vertical pipe 8 to provide all-round steam infiltration curing for the precast components placed on the support net 10. The support net 10 adopts a mesh structure, which is composed of multiple semi-cylindrical net columns 11. The semi-circular cross-sections of each net column 11 are connected end to end. This not only supports the precast components but also creates gaps between them, i.e., the gaps between two adjacent net columns 11. This improves the bottom steam curing effect of the precast components, thereby shortening the steam curing time and improving the curing efficiency.

[0027] In fact, the radial cross-sections of the multiple grid posts 11 supporting the grid 10 here form a wavy line cross-section.

[0028] Compared with existing technologies, this high-efficiency precast component steam curing device, after steam is introduced into the steam outlet plate 5, can achieve the rotation of the steam outlet plate 5 with the help of the guide holes, which improves the uniformity and range of steam outlet. Combined with the steam outlet of the horizontal pipe 7 and the vertical pipe 8, it can achieve all-round steam curing. The support net 10 can not only provide stable support for the precast component, but also increase the air permeability, which can not only improve the curing effect, but also improve the curing efficiency.

[0029] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
