Description

Technical Field

[0001] The utility model belongs to the technical field of concrete curing, and in particular relates to a concrete temperature and humidity synergistic curing device. Background Art

[0002] Concrete is a cementitious material made by mixing water and cement. It is typically mixed with sand, gravel, and additives. After setting, concrete requires curing. Due to its wide range of uses, concrete's actual on-site curing conditions are complex. To test the performance of concrete or new materials after actual on-site curing, specimens cured under the same environmental conditions as those used during on-site curing can be used to simulate the performance of concrete or new materials.

[0003] However, due to the long curing time of concrete and the complex and ever-changing on-site environment, existing technical measures have difficulty accurately reproducing on-site curing conditions. Therefore, targeting the two key factors affecting concrete curing, temperature and humidity, through computer-programmed coordinated control of the temperature-humidity environment, and accurately reproducing the on-site curing environment, is of great significance for the actual performance and quality testing of concrete or new materials. Utility Model Content

Therefore, it cannot be understood as a limitation on the present invention.

[0025] Working principle:

[0026] When the concrete temperature and humidity synergistic curing device is used, the two temperature and humidity sensors 8 are first used to detect the air parameters inside and outside the insulation box 1, and the data of the temperature and humidity sensors 8 inside and outside the insulation box 1 are compared to determine the required treatment of the outside air temperature and humidity. Since the air humidity control has a great influence on the gas temperature, the humidity control system 4 is first used to control the humidity, and then the heat exchanger 5 is used to control the temperature.

[0027] The outside air enters the heat preservation box 1 through the air filter 2. During the humidity control process, after comparison between the two temperature and humidity sensors 8, it is determined whether the outside air needs to be humidified or dehumidified. If humidification is required, the humidifier 9 is turned on. After the air is humidified, the humidification valve 10 is opened, and the humidity sensor 11 collects the humidity. If the humidity meets the requirements, the exhaust valve 2 15 is opened, and the air is sent to the heat exchanger 5. If the humidity does not meet the requirements, the dehumidification valve 13 is opened, and the air is sent to the refrigeration dehumidifier 14. The humidification valve 10 is closed, and the air enters the refrigeration dehumidifier 14 for refrigeration and dehumidification. The humidity sensor 11 collects the humidity again. If the humidity meets the requirements, the exhaust valve 2 15 is opened, and the air is sent to the heat exchanger 5. If the humidity still does not meet the requirements, the air is sent to the humidifier 9 for humidification again. This cycle repeats until the humidity meets the requirements.

[0028] If dehumidification is required, the refrigeration dehumidifier 14 is turned on and the air is dehumidified. The dehumidification valve 13 is opened and the humidity sensor 11 collects the humidity. If the humidity meets the requirements, the exhaust valve 15 is opened and the air is sent to the heat exchanger 5. If the humidity does not meet the requirements, the above cycle is repeated until the humidity meets the requirements. Then the exhaust valve 15 is opened and the air is sent to the heat exchanger 5.

[0029] After the air is sent into the heat exchanger 5, the exhaust valve 15 is closed to control the temperature of the air. The temperature sensor 6 collects the gas temperature and compares it with the required temperature. The temperature control system 3 starts to work and heats or cools the gas in the heat exchanger 5 through the heat-conducting copper tube. When the temperature collected by the temperature sensor 6 is consistent with the required temperature, the exhaust valve 7 is opened to send the air into the insulation box 1 on one side of the partition 16. At this point, a temperature and humidity control cycle process is completed. Multiple temperature and humidity control cycles are carried out in sequence to maintain consistency to achieve the purpose of coordinated control of temperature and humidity.
