Abstract
Description
Technical Field
[0001] This utility model belongs to the field of concrete component curing technology, specifically relating to a precast concrete component heating curing device. Background Technology
[0002] In modern architecture, precast concrete components are a major building material. Currently, steam curing is generally used in the production process to accelerate the hydration of concrete. Specifically, after the concrete components are formed, they are left at room temperature for a period of time to allow them to initially set before being placed in a curing device. Steam is sprayed onto the surface of the concrete components in the curing device to humidify and heat them, thereby promoting the setting and hardening of the concrete.
[0003] Existing concrete component curing devices typically require vents. When steam is sprayed into the curing device, air inside the device is discharged through the vents to maintain pressure balance between the device and the outside environment. However, the steam sprayed into the curing device results in a higher air temperature inside, and direct discharge from the vents leads to a waste of heat. Utility Model Content

[0014] (3) Beneficial effects
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention, through the setting of a curing mechanism, allows the hot and humid air inside the curing hood to be discharged from the exhaust port when steam is sprayed from the steam nozzle into the space between the curing hood and the outer frame. After flowing between the curing hood and the outer frame, it finally enters the exhaust pipe and is discharged again. This allows the hot and humid air discharged from the exhaust port to pass through the outer end of the curing hood, thus insulating the outer end of the curing hood and improving its heat preservation effect. This fully utilizes the discharged hot and humid air and avoids waste of resources.
[0017] This invention incorporates a dehumidification unit. When the base plate is installed on the underside of the exhaust pipe, the side plate and the mesh plate are fixed to the exhaust pipe. This allows the humid and hot air discharged from the exhaust pipe to pass through the activated carbon between the mesh plates, where the activated carbon absorbs some of the moisture, thus preventing the discharged air from becoming too humid and affecting the nearby working environment.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This specific embodiment is a precast concrete component heating and curing device, the structural schematic diagram of which is shown below. Figures 1 to 3As shown, the device includes a curing cover 1, with hinged doors 2 at both ends. A steam generator 3 is installed at the outer end of the curing cover 1. Curing mechanisms are located at both the inner and outer ends of the curing cover 1. Each curing mechanism includes an outer frame 401 fixedly connected to the outer side of the curing cover 1. U-shaped tubes 402 are installed at equal intervals on the inner side of the curing cover 1. Steam nozzles 403 are installed at equal intervals on the outer ends of the U-shaped tubes 402. A connecting pipe 404 is fixedly connected to the upper side of the outer frame 401. Connecting pipes 405 are fixedly connected at equal intervals to the lower end of the connecting pipe 404. A delivery pipe 406 is installed at the outer end of the steam generator 3. The end of the delivery pipe 406 furthest from the steam generator 3 is fixedly connected to the middle of the connecting pipe 404. The lower end of the connecting pipe 405 is fixedly connected to the upper end of the U-shaped tubes 402. An exhaust port is provided on the upper left side of the curing cover 1. When steam is sprayed from the steam nozzle 403 into the interior of the curing hood 1, the hot and humid air inside the curing hood 1 will be discharged from the exhaust port to the space between the curing hood 1 and the outer frame 401. After flowing between the curing hood 1 and the outer frame 401, it will finally enter the exhaust pipe 501 and be discharged. This allows the hot and humid air discharged from the exhaust port to pass through the outer end of the curing hood 1, thus insulating the outer end of the curing hood 1 and improving the insulation effect of the curing hood 1. The discharged hot and humid air is fully utilized, avoiding waste of resources.
[0027] Cooperate Figure 4 and Figure 5 A dehumidification unit is provided at the outer end of the outer frame 401. The dehumidification unit includes an exhaust pipe 501 fixedly connected to the lower right side of the front and rear ends of the outer frame 401. A base plate 502 is provided at the lower end of the exhaust pipe 501. Side plates 503 are fixedly connected to the front and rear ends of the upper side of the base plate 502. Mesh plates 504 are fixedly connected to the left and right sides of the side plates 503. Threaded rods 505 are fixedly connected to the left and right ends of the lower side of the exhaust pipe 501. A fixing ring 506 is connected to the outer side of the threaded rod 505. Circular holes are opened at the left and right ends inside the base plate 502. Internal threads are opened on the inner side of the fixing ring 506. The outer side of the threaded rod 505 is threaded to the inner side of the fixing ring 506. The upper side of the fixing ring 506 abuts against the left and right ends of the lower side of the base plate 502. The lower end of the exhaust pipe 501 is provided with a through groove. The outer sides of the side plate 503 and the mesh plate 504 are slidably connected to the inner side of the through groove. The upper sides of the side plate 503 and the mesh plate 504 abut against the inner top of the exhaust pipe 501. Activated carbon is filled between the side plate 503 and the mesh plate 504 above the base plate 502. Thus, when the base plate 502 is installed on the lower side of the exhaust pipe 501, the side plate 503 and the mesh plate 504 will be fixed in the exhaust pipe 501. This allows the hot and humid air discharged from the exhaust pipe 501 to pass through the activated carbon between the mesh plates 504, where the activated carbon absorbs some of the moisture, preventing the discharged air from becoming too humid and affecting the nearby working environment.
[0028] A rubber gasket is attached to the inside of the exhaust pipe 501. When the side plate 503 and the mesh plate 504 are installed inside the exhaust pipe 501, the rubber gasket inside the exhaust pipe 501 contacts the outside of the side plate 503 and the mesh plate 504, ensuring a seal at the contact points between the side plate 503 and the mesh plate 504 and the inside of the exhaust pipe 501. This allows the hot and humid air entering the exhaust pipe 501 from the outer frame 401 to be exhausted only after passing through the activated carbon inside the mesh plate 504.
[0029] Working principle: When curing precast concrete components, the concrete component to be cured is first pushed into the curing hood 1, then the sealing door 2 is closed, then the steam generator 3 is turned on, and high-temperature steam is input into the conveying pipe 406, then flows into the connecting pipe 405 through the connecting pipe 404, then into the U-shaped pipe 402, and finally sprayed out from the steam nozzle 403 onto the surface of the concrete component to heat and humidify it until the concrete component is completely solidified and hardened, then the sealing door 2 is opened and the concrete component is taken out.
[0030] All technical features in this embodiment can be freely combined according to actual needs.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
