Utility Model Content
[0005] The purpose of the utility model is to provide a recycled concrete temperature control box with setting time regulation, so as to solve the problem that when the curing box is in use, the placement device frame is in a static state, which may cause uneven heating and humidification distribution of the recycled concrete, resulting in reduced recycled concrete curing quality and efficiency.

[0011] Preferably, a placement groove is provided on the inner bottom surface of the temperature control box body, and a collection box is provided inside the placement groove.
[0012] Compared with the existing technology, the recycled concrete temperature control box with setting time regulation using the above technical solution has the following beneficial effects:
[0013] 1. During use, the rotating shaft, placement rack, and drive motor help achieve a more uniform moisture distribution. They can also help distribute heat more evenly to all parts of the recycled concrete, avoiding local overheating or insufficient heating. This improves the uniformity of moisture and temperature distribution during the recycled concrete curing process, promotes the coagulation and hardening of the recycled concrete, and enhances its strength and durability, thereby improving the quality and efficiency of curing.
[0014] Second, during use, the humidity sensor facilitates real-time monitoring of the humidity level inside the temperature control box and feeds the data back to the PLC controller.

The temperature sensor is electrically connected to the PLC controller and can transmit the collected temperature data to the PLC controller for processing. The PLC controller can automatically adjust the working state of the heating pipe according to the set temperature range to keep the temperature inside the box within the optimal range. This not only improves the automation level of the curing process, but also ensures that the recycled concrete can be cured under ideal temperature conditions, thereby improving the curing quality.
[0015] 3. During use, several through-holes are opened on the inner bottom surface of the placement rack, providing a more transparent curing environment for the recycled concrete placed on it. These through-holes not only facilitate the even distribution of steam and heat, but also promote air circulation inside the concrete, helping to expel excess moisture and gas, and improving the density and strength of the concrete. Through the combination of observation holes and tempered glass, staff can clearly observe the real-time conditions inside the temperature control box. Tempered glass not only has excellent light transmittance and impact resistance, but also effectively isolates the heat and humidity exchange inside and outside the box, ensuring accurate and safe observation. The provision of a collection box not only facilitates the handling and cleaning of dropped concrete by staff, but also improves the cleanliness and safety of the internal environment of the temperature control box, providing better conditions for the curing of recycled concrete.

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0022] like Figures 1-4 As shown, a recycled concrete temperature control box for setting time regulation includes a box door 1, which is rotatably connected to the front side of the outer wall of the temperature control box body 2 through a hinge. A plurality of air inlet holes 3 are opened on the right side of the outer wall of the temperature control box body 2. A PLC controller is fixed on the right side of the outer wall of the temperature control box body 2. A rotating shaft 4 is rotatably provided inside the temperature control box body 2. A plurality of placement racks 5 are fixed on the outer wall of the rotating shaft 4. A humidifying device 6 is fixed on the right side of the outer wall of the temperature control box body 2. The humidifying device 6 is electrically connected to the PLC controller. A connecting main pipe 7 is fixed to the output end of the device 6, and a number of connecting branch pipes 8 are fixed to the left side of the connecting main pipe 7. The several connecting branch pipes 8 are respectively fixed in the several air inlet holes 3. A rotating hole 9 is opened on the top surface of the temperature control box body 2. A drive motor 10 is fixed on the top surface of the temperature control box body 2. The drive motor 10 is electrically connected to the PLC controller. The output shaft of the drive motor 10 is fixedly connected to the top of the rotating shaft 4. A heating pipe 11 is fixed to the left side of the inner wall of the temperature control box body 2, and the heating pipe 11 is electrically connected to the PLC controller.
[0023] During use, the staff first places the recycled concrete that needs to be cured on the placement rack 5, then closes the box door 1, and starts the humidifying device 6 so that the steam generated by the humidifying device 6 enters the interior of the temperature control box body 2 from the connecting main pipe 7 through the connecting branch pipe 8. By starting the heating pipe 11, the concrete can be heated. At the same time, the staff starts the driving motor 10 to rotate the rotating shaft 4, thereby driving the placement rack 5 to rotate, so that the recycled concrete placed thereon is affected by steam in different directions, which helps to achieve a more uniform humidity distribution, and can also help to distribute heat more evenly to various parts of the recycled concrete, avoiding local overheating or insufficient heating, thereby improving the uniformity of humidity and temperature distribution during the curing process of the recycled concrete, promoting the coagulation and hardening of the recycled concrete, and improving its strength and durability, thereby improving the quality and efficiency of curing.
[0024] like Figure 1 and Figure 2 As shown, a fixing hole 12 is opened on the top surface of the temperature control box body 2, and a humidity sensor 13 is fixed inside the fixing hole 12. The humidity sensor 13 is electrically connected to the PLC controller.
[0025] During use, the humidity sensor 13 is used to monitor the humidity level in the temperature control box body 2 in real time, and the data is fed back to the PLC controller.

[0026] like Figures 1-4 As shown, a connection hole 14 is provided on the top surface of the temperature control box body 2 , a temperature sensor 15 is fixed inside the connection hole 14 , and the temperature sensor 15 is electrically connected to the PLC controller. A plurality of through holes 16 are respectively provided on the inner bottom surfaces of the plurality of placement racks 5 .
[0027] During use, the temperature sensor 15 facilitates real-time monitoring of temperature changes within the temperature-controlled box body 2. The temperature sensor 15 is electrically connected to the PLC controller and can transmit the collected temperature data to the PLC controller for processing. The PLC controller can automatically adjust the operating state of the heating tube 11 according to the set temperature range to maintain the temperature within the box within the optimal range. This not only improves the automation level of the curing process, but also ensures that the recycled concrete can be cured under ideal temperature conditions, thereby improving the curing quality. Several through holes 16 are opened on the inner bottom surface of the placement rack 5, providing a more transparent curing environment for the recycled concrete placed thereon. These through holes 4 not only facilitate the uniform distribution of steam and heat, but also promote air circulation within the concrete, helping to expel excess moisture and gas, and improving the density and strength of the concrete.
[0028] like Figure 1 、 Figure 2 and Figure 4 As shown, a plurality of observation holes 17 are provided on one side of the door 1 , and tempered glass 18 is fixed inside each of the observation holes 17 . A placement groove 19 is provided on the inner bottom surface of the temperature control box body 2 , and a collection box 20 is provided inside the placement groove 19 .
[0029] During use, the combination of observation hole 17 and tempered glass 18 allows staff to clearly observe the real-time conditions within the temperature-control box body 2. Tempered glass 18 not only offers excellent light transmittance and impact resistance, but also effectively isolates heat and humidity exchange between the inside and outside of the box, ensuring accurate and safe observation. The provision of collection box 20 not only facilitates the handling and cleanup of fallen concrete but also improves the cleanliness and safety of the environment within the temperature-control box body 2, providing better conditions for the maintenance of recycled concrete.
