Description

Technical Field

[0001] The utility model relates to the technical field of thermal stability evaluation, in particular to an auxiliary device for evaluating the thermal stability of chemical products. Background Art

[0002] The chemical product thermal stability assessment auxiliary device is a special device used to test and evaluate the thermal stability of chemical products. The device helps researchers understand the stability of products under high temperature conditions and possible chemical changes by simulating chemical reaction processes under specific temperature conditions. This is of great significance for the research and development, production and quality control of chemical products.

[0003] During the test, researchers first put the chemical product to be tested into the reaction vessel and then set the required temperature and time parameters. The heating system starts working, heating the reaction vessel to the set temperature and maintaining it for a certain period of time. During this process, the data acquisition and processing system monitors and records various data in real time. After the test, researchers can evaluate the thermal stability of the product by analyzing this data.

[0004] However, during the heating test, chemical products are generally directly placed in a container for heating, and local overheating or overcooling is prone to occur in the container, which is not conducive to maintaining the uniformity of heating of the chemical products, thereby affecting the accuracy of thermal stability evaluation. In addition, for situations where a large number of chemical products are required for thermal stability evaluation, repeated fixation and release work is rather cumbersome. Therefore, a chemical product thermal stability evaluation auxiliary device is proposed to improve the accuracy of thermal stability evaluation, and can automatically fix and release, which can greatly simplify the operation process.

[0031] The outside of the tray 10 is provided with a fixing assembly for chemical products, and the fixing assembly includes a rotating ring 12 arranged on the tray 10 and a plurality of fixing rods 15 arranged on the rotating ring 12. A support rod 3 is installed on the outside of the heating device 1. A sliding groove 4 is opened on the side of the support rod 3 close to the container 2. A threaded rod 5 is rotatably connected inside the sliding groove 4. A first servo motor 7 is installed at the end of the support rod 3 away from the heating device 1. The output shaft of the first servo motor 7 extends to one end inside the sliding groove 4 and is fixedly connected to the threaded rod 5. A movable rod 6 is slidably connected to the inside of the support rod 3, and the movable rod 6 is threadedly connected to the threaded rod 5. The size of the opening of the sliding groove 4 is adapted to the size of the movable rod 6, and the cross-sections of the sliding groove 4 and the movable rod 6 are convex.

[0032] The second servo motor 8 is installed at the end of the movable rod 6 away from the support rod 3, and the output shaft end of the second servo motor 8 passes through one end of the movable rod 6 and is installed with a push rod 9, the push rod 9 is rotatably connected to the movable rod 6, and the tray 10 is installed at the end of the push rod 9 away from the movable rod 6, the placement grooves 11 are opened on the tray 10 and are evenly distributed in a circle, and the placement grooves 11 run through the entire tray 10, an L-shaped rod 17 is installed on the outside of the container 2, and an extrusion rod 18 is installed on the side of the L-shaped rod 17 close to the rotating ring 12, and an extrusion groove 16 is opened at the position of the rotating ring 12 corresponding to the extrusion rod 18, the cross-section of the extrusion groove 16 is trapezoidal, and the extrusion rod 18 is on the movement trajectory of the extrusion groove 16.

[0033] In this embodiment, when it is necessary to evaluate the thermal stability of the chemical product, firstly, the water flow in the holding container 2 is heated to the required temperature by the heating device 1, and then the chemical products can be directly placed in the placement grooves 11 on the tray 10 respectively, and then the first servo motor 7 is started, and the threaded rod 5 is driven to rotate by the first servo motor 7. Since the threaded rod 5 and the movable rod 6 are threadedly connected, the threaded rod 5 drives the movable rod 6 to move along the sliding groove 4 while rotating, and at the same time drives the chemical products on the tray 10 to move to the water flow in the holding container 2 for heating, and then the second servo motor 8 is started, and the push rod 9 is driven to rotate slowly by the second servo motor 8, and when the push rod 9 rotates, it drives the tray 10 The chemical products are rotated, and by driving the chemical products to rotate slowly, the chemical products can be better exposed to the heat source, avoiding local overheating or overcooling in the container 2, which helps to ensure that the chemical products are heated more evenly, thereby improving the accuracy of thermal stability evaluation, and when the tray 10 drives the chemical products to rotate, the stirring rod 19 can be driven to rotate, and the water flow is stirred by the rotation of the stirring rod 19, and the guide rod 20 is driven to rotate at the same time.

[0034] Embodiment 2

[0035] like Figure 1-6 As shown, based on the first embodiment, the rotating ring 12 is rotatably connected to the outside of the pushing rod 9, and a torsion spring 13 is installed on the outside of the rotating ring 12, a circular plate 14 is installed at the end of the torsion spring 13 away from the rotating ring 12, and the circular plate 14 is fixedly connected to the pushing rod 9, the torsion spring 13 is sleeved on the outside of the pushing rod 9, and a fixed rod 15 is installed on the outside of the rotating ring 12. The number of the fixed rods 15 is multiple groups and is evenly distributed around the circumference, and the positions of the fixed rods 15 correspond to the positions of the placement grooves 11 respectively.

[0036] In this embodiment, when the chemical product is placed in the placement groove 11 on the tray 10 and then the tray 10 is moved to the containing container 2, the squeezing rod 18 is moved to the outside of the squeezing groove 16. At this time, there is no squeezing of the rotating ring 12 by the squeezing rod 18, and the torsion spring 13 in the contracted state is reset, and at the same time, the rotating ring 12 is driven to reset, so that the multiple fixing rods 15 on the rotating ring 12 are respectively fixed to the chemical products on the corresponding placement grooves 11 at the same time. When the thermal stability evaluation of the chemical product is completed, it is necessary to move the tray 10 to the outside of the containing container 2. First, the second servo motor 8 is used to move the chemical product to the outside of the containing container 2. The tray 10 is reset and then moved to the outside of the container 2.
