Description

Technical Field

[0001] This utility model relates to the field of curing kiln technology, and in particular to a heating and humidifying curing kiln for precast concrete components. Background Technology

[0002] A curing kiln is a specialized piece of equipment used for curing concrete components. It stores concrete components in the kiln and goes through several stages, including settling, heating, maintaining a constant temperature, and cooling, to ensure that the cement components reach the required solidification strength. Concrete needs a specific environment and temperature to solidify properly; otherwise, it is prone to reduced strength, shrinkage cracks, peeling, and sanding, which can seriously affect the quality of the concrete. Therefore, in the production process of precast concrete components, it is necessary to keep the concrete warm and moist for curing, which is generally carried out through a curing kiln.

[0003] An existing heating and humidifying curing kiln for precast concrete pipe pile components (Announcement No.: CN217992930U) has at least the following drawbacks:

[0004] In the aforementioned patent, when curing precast concrete components, it is necessary to place the precast concrete components into a kiln. However, precast concrete components are generally heavy and inconvenient to move in and out. At the same time, precast concrete components need to be supported by brackets and placed on the inner ground, which makes the operation more troublesome and inconvenient to use, and has certain limitations.

A winch 8 is fixedly installed on the top surface of the fixing plate 10. A connecting hook 9 is fixedly installed at one end of the steel cable of the winch 8. A first fixing pipe 11 is fixedly installed on the top surface inside the curing kiln 1. A movable plate 12 is movably sleeved inside the first fixing pipe 11. A second fixing pipe 13 is fixedly installed on the bottom surface of the movable plate 12. Several first circular through holes are opened on both sides of the second fixing pipe 13.

[0027] In this embodiment, a threaded hole 16 is provided on one side of the movable plate 12, and a threaded post 17 is threadedly connected to the inner circular wall of the threaded hole 16. Two support plates 19 are fixedly installed on the inner top surface of the curing kiln 1, and a drive motor 18 is fixedly installed between the two support plates 19.

[0028] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When the user needs to heat and humidify several precast component bodies 2 through the set curing kiln hopper 1, it will be connected to the steam generator's outlet pipe. The steam generator is existing technology and will not be described in detail. At this time, the user uses the connecting hook 9 on the left side to hook the fixing ring 7, starts the winch 8 to retract the steel cable, and pulls the fixing ring 7 through the connecting hook 9. This causes the fixing ring 7 to pull the moving frame 4, which rolls inside the support rail 6 via the moving wheels 5, thus moving the moving frame 4. The precast component body 2 is then removed from the interior of the curing kiln 1. The operator places the precast component body 2 onto the internal platform of the moving frame 4. Then, using the winch 8 on the right and the connecting hook 9, the moving frame 4 is moved in the opposite direction, causing several precast component bodies 2 to enter the interior of the curing kiln 1. The moving frame 4 is then limited by the limiting plate 21 and rubber plate 22 to prevent the moving wheels 5 from derailing from the support rail 6. Following the same method, another precast component body 2 is placed inside the moving frame 4, and the moving frame 4 is moved into the interior of the curing kiln 1. Then, the roller shutter door 23 is activated to seal both sides of the curing kiln chamber 1. The steam generator is then activated to deliver steam into the interior of the second fixed pipe 13, which is then sprayed out through the support pipe 14 and nozzles 15. Simultaneously, the drive motor 18 is activated to drive the threaded column 17 to rotate, converting the rotational motion of the threaded column 17 and the threaded hole 16 into linear motion. This causes the moving plate 12 to move back and forth inside the first fixed pipe 11, allowing the nozzles 15 to move while simultaneously spraying air to heat and moisten the precast component body 2. The moving nozzles 15 also ensure more uniform heating and humidification. After curing is complete, the steam generator is activated... After the roller shutter door 23 is opened, the movable frame 4 can be moved out of the curing kiln 1 in the manner described above. This achieves the combined effect of heating and humidifying the precast component body 2. The movable frame 4 supports several precast component bodies 2, allowing them to be placed outside the kiln, which facilitates operation. The movable wheels 5, winch 8, and support rails 6 make it easy to move the precast component bodies 2 in and out of the curing kiln 1, which is convenient for use. At the same time, the movable nozzles 15 make the heating and humidification effect on the precast component bodies 2 more uniform, ensuring the curing effect.
