[0007] Furthermore, the front side of the dry shrink curing box is connected to a secondary sealing door and a control cabinet door that respectively cooperate with the circulating air cavity and the control box, facilitating auxiliary maintenance and control operations.
[0008] Furthermore, a first sealing glass is connected to the main sealing door, and a second sealing glass is provided on the front side of the dry shrink curing box body to cooperate with the water cavity, so as to facilitate the observation of the internal situation.
[0009] Furthermore, a humidity sensor is connected inside the circulating air cavity, and a temperature and humidity sensor is connected to the top of the sealed cavity to facilitate sensing the corresponding temperature and humidity during operation.
[0010] Furthermore, a heat dissipation and dehumidification fan communicating with the sealed cavity is connected to the rear side of the main body of the dry shrink curing box.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.
[0021] Combined with appendix Figure 1-4 A mortar drying shrinkage curing device includes a drying shrinkage curing box body 1. The front side of the drying shrinkage curing box body 1 is provided with multiple sealed cavities 2. The front side of the drying shrinkage curing box body 1 is connected to a main sealing door 3 that matches the sealed cavities 2. The rear side of the sealed cavities 2 is connected to a heating plate 14 and a cooling plate 29. The side of the drying shrinkage curing box body 1 is connected to a control box 13. This is a common sealing cavity 2 for temperature control, which facilitates temperature control operations.
[0022] The main body 1 of the drying and curing chamber contains a circulating air chamber 4 located on the outside and bottom of multiple sealed cavities 2. The front of the main body 1 is connected to a secondary sealed door 24 and a control cabinet door 15, which respectively cooperate with the circulating air chamber 4 and the control box 13. The control cabinet door 15 typically has a control panel for easy touchscreen control of the electrical components within the equipment. A PLC controller and corresponding controllers are also installed in the control box 13 to facilitate the operation of the electrical components. These are common electrical components and will not be described in detail. A water chamber 11 is connected to one side of the bottom of the main body 1. An ultrasonic humidifier 12 is connected between the circulating air chamber 4 and the water chamber 11. A main exhaust fan 5 and a circulating air outlet 6, communicating with the circulating air chamber 4, are respectively connected to both sides of the sealed cavities 2. The circulating air chamber 4... The inner side is connected to a first air collecting hood 7 that works with the main exhaust fan 5. The circulating air cavity 4 is connected to a second air collecting hood 8 that works with the circulating air outlet 6. The first air collecting hood 7 and the second air collecting hood 8 are respectively connected to a first electric control valve 9 and a second electric control valve 10. The first electric control valve 9 and the second electric control valve 10 can be set as one-way valves or flow control valves to facilitate moisture circulation while ensuring internal sealing. This equipment uses the internal circulating air cavity 4 and an ultrasonic humidifier 12 to control the humidity inside the circulating air cavity 4. Then, the main exhaust fan 5 and the circulating air outlet 6 set on both sides of the sealed cavity 2, together with the air collecting hood and the electric control valve, can accurately control the humidity inside each sealed cavity 2. The heating plate 14 and the cooling plate 29 can be used to control the temperature inside the sealed cavity 2.
[0023] The main sealing door 3 is connected to a first sealing glass 16, and the front side of the dry shrink curing box body 1 is provided with a second sealing glass 25 that matches the water cavity 11. The front side of the dry shrink curing box body 1 is connected to a water inlet valve pipe 26 and a drain valve pipe 27 that communicate with the water cavity 11.
[0024] A lighting lamp 23 is connected to the top of the sealed cavity 2. A humidity sensor 28 is connected to the circulating air cavity 4. A temperature and humidity sensor 19 is connected to the top of the sealed cavity 2. A heat dissipation and dehumidification fan 20 communicating with the sealed cavity 2 is connected to the rear side of the dry shrink curing box body 1. A third air collecting hood 21 cooperating with the heat dissipation and dehumidification fan 20 is connected to the rear side of the dry shrink curing box body 1. A third electric control valve 22 is connected to the third air collecting hood 21. The system operates by sensing the corresponding temperature and humidity. Under normal circumstances, the humidity inside the circulating air cavity 4 should be maintained above 80% to facilitate the input of moisture into the sealed cavity 2 for humidity control. When the temperature or humidity inside the sealed cavity 2 is high, the heat dissipation and dehumidification fan 20 and the third electric control valve 22 can be activated to exhaust heat and moisture.
[0025] The bottom of the sealed cavity 2 is provided with a sliding plate 17 for limiting sliding. The bottom of the sealed cavity 2 is provided with multiple rolling rollers 18 rotatably connected below the sliding plate 17. That is, when inserting and removing the specimen, the sliding plate 17 can be pulled out stably for operation, which facilitates the insertion and removal operation.
