Description

Technical Field

[0001] The utility model relates to the field of detection equipment, in particular to a temperature and humidity control device for special mortar detection. Background Art

[0002] Special mortar mainly uses cement as the binding material. When in use, water or matching emulsion is directly added on the construction site and mixed, and then applied to the wall or the ground. Generally, it has a certain initial strength about 12 hours after construction. As time goes by, the strength continues to increase. Generally, the strength is basically stable after dozens of days.

[0003] The curing process of special mortar is a very complex physical and chemical reaction process. The changes in temperature and humidity of the external environment directly affect the speed of this reaction process. If the external temperature is too high, the water inside the mortar will evaporate quickly and cannot ensure the normal hydration and hardening of the mortar. When the temperature is too low, the hydration process of the mortar becomes very slow or may even stop. At the same time, it may be frozen and seriously affect the strength development of the mortar. The external humidity will affect the rate of water dissipation on the surface of the mortar, thereby affecting the setting time and water absorption time of the mortar.

[0004] The special mortar is tested to detect the setting and hardening rate of the special mortar under different temperatures and humidities, so as to obtain the setting and hardening rate curve of the mortar, which is of guiding significance for construction personnel to choose construction environment conditions. When testing, the special mortar sample needs to be placed in an experimental environment with controllable temperature and humidity, and a temperature and humidity control device needs to be used.

[0005] The existing temperature and humidity control device generally adopts a box structure, for example, the patent number is CN204143285U, and the name is a temperature and humidity calibration box. Its specific content is: providing the following technical scheme, the temperature and humidity calibration box includes a temperature and humidity detection system, a control system and a machine pump system, the control system is respectively communicated with the temperature and humidity detection system and the machine pump system, the temperature and humidity detection system is connected to the machine pump system through a ventilation pipe, the temperature and humidity detection system includes a temperature and humidity detection box, the side wall of the temperature and humidity detection box is provided with a movable sealing port for the input and output lines of the detected sensor and a transparent glass observation window, the temperature and humidity detection box is provided with a temperature and humidity detection cavity, a cold light source lighting lamp, a hanging structure, instruments for temperature and humidity detection, an air inlet and an air outlet.

[0006] The above-mentioned temperature and humidity control device is not equipped with a circulating air duct, which may easily cause poor air flow and make it difficult to form a uniform and stable temperature and humidity environment. At the same time, there is no separation between the subsystems. For example, sensitive electronic components such as the control system and the pump system are easily affected by moisture and temperature. The treatment of condensed water is not considered, and the dripping of condensed water will affect the accuracy of the detection. Utility Model Content
