Description

Technical Field

[0001] The invention relates to the technical field of oxidation cylinder experiments, and in particular to a device and a method for testing and measuring the reaction rate of copper oxidation. Background Art

[0002] Testing the reaction rate of copper oxide solution helps to understand the kinetic characteristics of the reaction and evaluate the effects of different temperatures, concentrations and reaction conditions on the reaction rate. By real-time monitoring of the reaction rate, the reaction conditions can be optimized, production efficiency can be improved, and the safety and stability of the reaction process can be ensured to avoid adverse results caused by too fast or too slow reactions. For glass reactors, water bath heating is a common temperature control method. By uniformly heating the reactor, the stability of the reaction temperature is ensured, local overheating or cooling is prevented, thereby improving the uniformity and controllability of the reaction. In addition, water bath heating can also avoid excessive temperatures or glass reactor breakage caused by direct heating.

[0003] In the prior art, some glass reactor water bath heating methods are to fix multiple heating rods to the inside of a container in contact with the glass reactor, and the heating rods heat the water stored in the container. However, the method of fixing the heating rods inside the container has many disadvantages. First, even if the heating rods are powered off, the residual heat of the heating rods causes the water bath temperature to continue to rise, resulting in difficulty in accurately controlling the temperature. Especially when the temperature needs to be strictly controlled during the reaction process, the residual heat may cause the temperature to exceed the standard, thereby affecting the stability of the reaction and the quality of the product. In addition, the heating rods cannot be removed from the water bath container, and scale will accumulate after long-term use. The scale forms an insulating layer on the surface of the heating rods, which hinders heat conduction, resulting in a decrease in heating efficiency and a longer time to reach the required temperature. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that some glass reactors in the prior art are heated in a water bath by fixing multiple heating rods to the inside of a container in contact with the glass reactor, and the heating rods heat the water source stored in the container. However, the method of fixing the heating rods in the container has many disadvantages. On the one hand, even if the heating rods are powered off, the residual heat of the heating rods causes the water bath temperature to continue to rise, resulting in difficulty in accurately controlling the temperature. Especially when the temperature needs to be strictly controlled during the reaction process, the residual heat may cause the temperature to exceed the standard, thereby affecting the stability of the reaction and the quality of the product. In addition, the heating rods cannot be removed from the water bath container, and scale will accumulate after long-term use.

[0014] A method for testing the reaction rate of copper oxide comprises the following steps: S1: Conduct a copper oxide reaction experiment. At this time, the heating rod is inserted into the water bath ring to heat the external water source connected to the water bath ring. The water bath ring heats the glass reactor in a water bath. The copper oxide reaction reagent is introduced into the glass reactor through the injection tube. The stirring motor stirs the copper oxide reaction reagent through the stirring blades. At the same time, the pH sensor and conductivity sensor installed on the top of the glass reactor obtain the copper oxide reaction rate.

[0015] S2: After the oxidation cylinder reaction experiment is completed, the controller controls the driving assembly, which drives the water bath ring to move downward, and at the same time drives multiple heating rods to move to the top of the collecting ring through the expansion assembly. At the same time, the horizontal U-rod in the expansion assembly drives the collecting ring to move upward through the reversing assembly. The scraper ring on the collecting ring passes through the heating rod, and the scale attached to the surface of the heating rod is scraped off and collected inside the collecting ring.

[0016] Compared with the prior art, the present invention has the following advantages: 1. The structure of the present invention for water-bath heating of a glass reactor is a water-bath ring, a collecting ring is sleeved on the outer wall of the water-bath ring, and a driving assembly is arranged under the water-bath ring. The driving assembly can drive the heating rod to move out of the water-bath ring after the heating rod is powered off. When the heating rod is powered off, moving out of the water-bath ring can quickly reduce the influence of residual heat on the water-bath temperature, avoid the residual heat of the heating rod to continue to heat the water-bath container, avoid temperature fluctuations caused by the residual heat of the heating rod, thereby achieving more precise temperature control and ensuring temperature stability during the reaction. When the heating rod is moved out of the water-bath ring, overheating can be effectively prevented, and the potential safety hazard caused by excessive temperature can be reduced. In particular, after the reaction is completed, unnecessary heat accumulation can be quickly prevented through the automatic rod moving system.

[0017] 2. One of the core components of the driving assembly of the present invention is the expansion support assembly. Since the collecting ring is debugged on the outer wall of the water bath ring, when the driving assembly drives the heating rod to move out from the inside of the water bath ring, a plurality of heating rods are driven to move to the top of the collecting ring by a purely mechanical structure, waiting for the scraping assembly inside the collecting ring to scrape the scale on the outer wall of the heating rod. On the one hand, the collecting ring can automatically scrape and collect the scale. The combination of the collecting ring and the scraping assembly makes the scale removal process automatic. The relative movement of the heating rod and the scraping assembly is driven by the mechanical structure to avoid manual operation, greatly improve the cleaning efficiency and accuracy, and reduce manual intervention and operation risks. On the other hand, the scale is scraped off in a timely and automatic manner to avoid the long-term accumulation of scale on the surface of the heating rod. This not only improves the heating efficiency, but also prevents the damage of scale to the heating rod, effectively extending the service life of the equipment. The scraping of scale ensures the direct contact between the surface of the heating rod and the water source of the water bath, and maintains the heating efficiency. Without the interference of scale, the heating rod can transfer heat more efficiently and improve the overall heating performance of the system.

[0018] 3. One of the core components of the driving assembly of the present invention is the expansion assembly, and a reversing assembly is arranged under the expansion assembly. When the driving assembly drives the heating rod to move relatively out of the water bath ring, the collecting ring will be driven upward through the reversing assembly to connect with multiple heating rods. There is no need for multiple heating rods to be displaced in the vertical direction, thereby reducing the layout and guiding pressure of the power lines of multiple heating rods on the entire device. In general, the driving assembly is designed with a linkage of the expansion assembly, the reversing assembly and the collecting ring. The whole process only requires the program to control one vertical cylinder, which reduces the complexity of the program and the difficulty of equipment maintenance. Through automation and precise control, not only the cleaning efficiency and heat utilization efficiency of the heating rod are improved, but also the manual operation is reduced, thereby improving the overall safety, stability and economy of the equipment.

[0041] A vertical cylinder 19 is symmetrically fixedly arranged at the bottom of the support plate 3, and a horizontal U-rod 18 is fixedly arranged at the output end of the vertical cylinder 19 after passing through the support plate 3. The bottom of the side of the horizontal U-rod 18 is fixedly connected to the side of the water bath ring 16. The collecting ring 20 is sleeved on the outer wall of the water bath ring 16, and a driven gear rod 24 is symmetrically fixedly arranged on the outer wall of the collecting ring 20. The side of the driven gear rod 24 is stably meshed with the switching gear 22, and the other side of the switching gear 22 is stably meshed with an active gear rod 21, which is fixedly connected to the side of the horizontal U-rod 18. The switching gear 22 is rotatably connected to the side of the support seat 23. The bottom of the support seat 23 is fixedly connected to the top of the support plate 3 by bolts. A scraper ring 30 is movably inserted into the collecting ring 20 in the vertical direction. The top of the scraper ring 30 has a circular array of scraper holes 31. The bottom of the scraper ring 30 is symmetrically fixedly connected with an inverted U rod 32, which is used to support the scraper ring 30 inside the collecting ring 20. The diameter of the scraper hole 31 is the same as the diameter of the heating rod 29.

[0042] The bottom of the inverted U-rod 32 is overlapped with the inner cavity of the collecting ring 20, the interior of the expansion tube 15 is hollow, and a closed ring 17 is fixedly connected to the top of the expansion tube 15. The outer wall of the expansion tube 15 is provided with a wide vertical surface 151, an inclined surface 152 and a narrow vertical surface 153 in sequence along the vertical direction.

[0045] When multiple heating rods 29 are driven to expand and move to just above the collecting ring 20, the horizontal U-rod 18 in the expansion assembly drives the collecting ring 20 to move upward through the reversing assembly, and the scraper ring 30 on the collecting ring 20 passes through the heating rods 29, and the scale attached to the surface of the heating rods 29 is scraped off and collected inside the collecting ring 20.
