Description

Technical Field

[0001] This invention belongs to the field of experimental device technology, specifically a device for experimental testing of the heat of hydration of large-volume concrete in a desert environment. Background Technology

[0002] Heat of hydration refers to the heat released when a substance reacts chemically with water. It is a key performance indicator of cementitious materials such as cement. The generation of heat of hydration has a significant impact on the quality of concrete components, especially when the concrete component is large in volume. Due to the difference in heat dissipation between the inside and the surface of the concrete, secondary temperature stress is generated. When the temperature difference between the inside and outside of the concrete is particularly large, the large secondary temperature stress may cause cracking of the concrete component, which in turn leads to durability and safety risks during operation. Due to its large volume, the internal temperature changes of large-volume concrete during the release of heat of hydration are complex, which can easily lead to temperature cracks, thus affecting the durability and safety of the concrete structure. Therefore, accurate measurement and in-depth research on the heat of hydration characteristics of large-volume concrete in desert environments are crucial for ensuring the quality of infrastructure construction in desert areas. The experimental apparatus for heat of hydration is a key tool in this research, and its performance directly determines the accuracy and reliability of the experimental data.

[0003] Existing experimental apparatuses for the heat of hydration of large-volume concrete in desert environments employ a single, simple rotary mixing method. This fails to ensure thorough mixing of the cement and water components, resulting in uneven mixing and numerous dead zones. Consequently, the heat of hydration release process of the concrete in the experiment cannot accurately reflect the actual situation, affecting the accuracy of the experimental results. Furthermore, the temperature control function of existing apparatuses is not flexible enough to adjust the detection environment temperature in a timely manner according to the complex and variable temperature conditions of the desert environment, failing to meet different experimental needs. During the transfer of storage tanks, most of the time and effort is spent manually moving the tanks up and down, which reduces experimental efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an apparatus for testing the heat of hydration of large-volume concrete in a desert environment. A motor drives a threaded rod to rotate, causing a moving rod and scraper to adhere to the inner wall of the storage tank. A motor then drives a transmission gear, which in turn rotates a rotating ring and a fixed cover, further rotating the moving rod, scraper, and stirring rod. During rotation, the stirring rod rotates due to the meshing of the gear and the fixed ring. This combined motion allows for uniform and rapid mixing of cement and water. Simultaneously, the scraper removes cement from the inner wall of the storage tank, significantly reducing dead zones and ensuring thorough mixing of cement and water, thus improving the accuracy and reliability of experimental results. Furthermore, during mixing, a temperature-regulating rod rotates with the fixed cover, allowing for temperature adjustment of the storage tank. The ambient temperature can be flexibly adjusted according to actual usage needs to meet different experimental requirements. An adjustment mechanism allows for the adjustment of the vertical position and angle of the mixing and transfer mechanism. With the cooperation of the mixing and transfer mechanism, the storage tank can be quickly detached from the heat of hydration measuring instrument, facilitating easy transport of the storage tank, saving time, and improving experimental efficiency.

[0040] The following is a detailed description of the method of using a device for testing the heat of hydration of large-volume concrete in a desert environment, provided by an embodiment of the present invention. The method of use includes the following steps: Step 1: Transfer storage tank 5: Before the experiment begins, the storage tank 5 is placed outside the heat of hydration measuring instrument 1, and cement and water are placed in the storage tank 5. Then, the rotating motor 207 is turned on, and the rotating motor 207 drives the rotating gear 206 to rotate. Through the meshing of the rotating gear 206 and the connecting gear 205, the rotating tube 204 drives the connecting rod 208 and the temperature sensor 3 to rotate. The temperature sensor 3 drives the mixing and transfer mechanism 4 to rotate. The adjusting motor 201 is turned on, which drives the fixed threaded rod 202 to rotate. The fixed limiting rod 203 limits the rotation of the fixed threaded rod 202. The moving block 209 drives the temperature sensor 3 and the mixing transmission mechanism 4 to move until the mixing transmission mechanism 4 is located inside the storage tank 5. Then, the connecting motor 423 is turned on, which drives one of the fixed bevel gears 424 to rotate. Through the meshing of the five fixed bevel gears 424 and the mounting bevel gear 425, the connecting threaded rod 418 rotates. Through the limiting of the fixed rod 419, the moving plate 420 pushes the moving rod 421 and the scraper 422 to move. The multiple moving rods 421 and scrapers 422 are locked inside the storage tank 5. Then, the adjusting mechanism 2 is turned on to lift the storage tank 5, so that the storage tank 5 is aligned with the fixed base 401. The mounting motor 412 drives the transmission gear 411 to rotate, and through the transmission... The meshing of the moving gear 411 and the rotating gear 410 causes the rotating ring 409 to drive the fixed cover 406 to rotate, so that the hole on the fixed cover 406 aligns with the docking rod 405. At this time, the connecting ring 404 limits the storage tank 5 to the fixed base 401. Step 2: Mixing and stirring: When mixing cement and water, turn on the connecting motor 423 and adjust the connecting threaded rod 418 to rotate, so that the moving rod 421 and the scraper 422 are in contact with the inner wall of the storage tank 5. Then, turn on the installation motor 412 to drive the transmission gear 411 to rotate. Through the meshing of the transmission gear 411 and the rotating gear 410, the rotating ring 409 drives the fixed cover 406 to rotate, and the fixed cover 406 drives the moving rod 421 and the scraper 422 to rotate. Simultaneously, the stirring rod 415 rotates. Through the meshing of the installed gear 414 and the fixed gear ring 413, the stirring rod 415 rotates while rotating on its own axis. At the same time, the fixed cover 406 drives the docking rod 405 and the temperature regulating rod 403 to rotate, which can evenly and quickly stir cement and water, and can also mix the cement on the inner wall of the storage tank 5, reducing the dead corners of the stirring. Step 3, temperature regulation and testing: While stirring, the temperature regulating rod 403 can also be rotated to regulate the temperature of the storage tank 5. According to the actual use needs, the temperature of the testing environment of the storage tank 5 can be adjusted by the temperature regulating rod 403. After the test is completed, the storage tank 5 can be quickly removed from the hydration heat measuring instrument 1 by the adjustment mechanism 2, which is convenient for the user to transfer the storage tank 5 up and down.
