Description

Technical Field

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

[0002] Precast concrete components are the process of prefabricating concrete parts of buildings or structures in a factory or on-site. During the manufacturing process, in order to enable the formed concrete components to obtain demolding strength as soon as possible, accelerate the turnover of formwork, improve production efficiency, and increase output, curing measures that accelerate concrete hardening are required. Steam curing kilns are one of the more common curing equipment.

[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, steam is sprayed out through plastic nozzles to cure precast concrete components. However, the number of plastic nozzles is only one on each side, which limits the spraying range. Consequently, it is difficult to spray steam evenly on the outside of the precast components. At the same time, the steam distribution speed in the kiln is slow and uneven, which affects the curing efficiency and has certain limitations. Utility Model Content

[0026] 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 cure the precast concrete component using the curing kiln 1, the roller shutter 2 is activated and rolled up. Then, the moving vehicle 22 is pulled to move most of its body out of the curing kiln 1. Simultaneously, the baffle 25 limits and blocks the moving vehicle 22, preventing it from colliding with the first moving chamber 10. The precast concrete component is then placed on the top of the moving vehicle 22. The moving vehicle 22 is then pushed into the curing kiln 1 and reset. Afterwards, the self-locking motor 16 is activated to drive the gear 17 to rotate, causing the gear 17 and the tooth groove 19 to engage, allowing the second moving chamber 15 to rise and fall inside the moving tube 5, thus moving the first moving chamber 10 up and down. This allows the first moving chamber 10 to move closer to the precast concrete component. Therefore, by setting... The roller shutter door 2 is closed, and the steam generator 3 is started to deliver a large amount of steam to the interior of the fixed chamber 11 through the exhaust pipe. Then, through the connecting pipe 14 and the air inlet 13, the steam inside the fixed chamber 11 is delivered to the interior of the fixed chamber 11 through the connecting pipe 14, so that the steam is sprayed out through the nozzle 12, so that the steam can be sprayed to the outside of the precast concrete component from the top, bottom and left and right directions. At the same time, the drive motor 8 is started to drive the threaded column 7 to rotate, so that the threaded hole 6 and the threaded column 7 convert the rotational motion into linear motion, so that the moving pipe 5 and the fixed chamber 11 move laterally under the support of several slide rails 4 to carry out steam curing. This achieves the comprehensive effect of curing the precast concrete component, so that the steam can be sprayed to all parts of the precast concrete component, ensuring the curing effect. At the same time, it also speeds up the speed of steam entering the curing kiln 1 and distribution, improves the distribution uniformity, and thus improves the curing efficiency, which is quite practical.
