It includes a glass reaction kettle, a water bath ring, and a collection ring. The structure for water bath heating of the glass reaction kettle in the present invention is the water bath ring.

Description

Technical Field

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

[0002] Detecting the reaction rate of copper oxide solution helps to understand the kinetic characteristics of the reaction, evaluate the influence of different temperatures, concentrations and reaction conditions on the reaction rate. By monitoring the reaction rate in real time, the reaction conditions can be optimized, production efficiency can be improved, and the safety and stability of the reaction process can be ensured, avoiding adverse results caused by too fast or too slow reactions. For a glass reaction kettle, water bath heating is a common temperature control method. By uniformly heating the reaction kettle, 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 too high temperature or glass kettle rupture caused by direct heating.

[0003] In the prior art, some water bath heating methods for glass reaction kettles are to fix multiple heating rods inside a container in contact with the glass reaction kettle. The heating rods heat the water source stored inside the container. However, the method of fixing the heating rods inside the container has many disadvantages. First of all, even after the heating rods are powered off, the residual heat of the heating rods causes the water bath temperature to continue to rise, making it difficult to precisely control the temperature. Especially when strict temperature control is required during the reaction process, the residual heat may cause the temperature to exceed the standard, thereby affecting the stability of the reaction and the product quality. 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, hindering heat conduction, resulting in a decrease in heating efficiency and requiring a longer time to reach the required temperature. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the prior art that some water bath heating methods for glass reaction kettles are to fix multiple heating rods inside a container in contact with the glass reaction kettle. The heating rods heat the water source stored inside the container. However, the method of fixing the heating rods inside the container has many disadvantages. On the one hand, even after the heating rods are powered off, the residual heat of the heating rods causes the water bath temperature to continue to rise, making it difficult to precisely control the temperature. Especially when strict temperature control is required during the reaction process, the residual heat may cause the temperature to exceed the standard, thereby affecting the stability of the reaction and the product quality. 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, hindering heat conduction, resulting in a decrease in heating efficiency and requiring a longer time to reach the required temperature. And a device and method for testing and measuring the reaction rate of copper oxide are proposed.

Stirring blades are equidistantly arranged on the vertical shaft in the vertical direction. The front view cross-sectional shape of the stirring blade is U-shaped.

[0009] Optionally, vertical cylinders are symmetrically and fixedly arranged at the bottom of the support plate. The output ends of the vertical cylinders pass through the support plate and are fixedly provided with a horizontal U-shaped rod. The bottom of the side of the horizontal U-shaped rod is fixedly connected to the side of the water bath ring. The spreading component includes a spreading cylinder, a horizontal column, and a connecting spring. The top of the vertical folding rod is fixedly connected with a horizontal column in the horizontal direction. A vertical ring is slidably arranged on the outer wall of the horizontal column.

[0010] Optionally, one end of the connecting spring is fixedly connected to the outer wall of the vertical ring, and the other end of the connecting spring is fixedly connected to the side of the vertical folding rod.

[0011] Optionally, the collection ring is sleeved on the outer wall of the water bath ring. Driven racks are symmetrically and fixedly arranged on the outer wall of the collection ring. The side surface of the driven rack is stably engaged with a switching gear. The other side surface of the switching gear is stably engaged with a driving rack. The driving rack is fixedly connected to the side surface of a horizontal U-shaped rod. The switching gear is rotatably connected to the side surface of a support seat. The bottom of the support seat is fixedly connected to the top of a support plate by bolts.

[0012] Optionally, a descaling ring is inserted into the collection ring in the vertical direction. Scaling holes are circularly arrayed at the top of the descaling ring. Inverted U-shaped rods are symmetrically and fixedly connected to the bottom of the descaling ring. The bottoms of the inverted U-shaped rods are placed on the inner cavity of the collection ring.

[0013] Optionally, the inside of the expansion cylinder is in a hollow state. A closed ring is fixedly connected to the top of the expansion cylinder. Wide vertical surfaces, inclined surfaces and narrow vertical surfaces are sequentially formed on the outer wall of the expansion cylinder in the vertical direction. The top side surface of the horizontal U-shaped rod is fixedly connected to the side surface of the wide vertical surface. One end of the horizontal column arranged in a hemispherical shape contacts the wide vertical surface or the inclined surface or the narrow vertical surface of the outer wall of the expansion cylinder.

[0014] Optionally, the material of the outer protection cylinder is transparent acrylic board. A controller is fixedly arranged on the side surface of the outer protection cylinder. Inverted U-shaped grooves are symmetrically formed at the bottom of the side surface of the outer protection cylinder. AC pipes are fixedly connected to both ends of the water bath ring. The AC pipes extend out from the inverted U-shaped grooves.

[0015] A method for testing and measuring the reaction rate of copper oxide includes the following steps:

[0016] S1: Conduct a copper oxide reaction experiment. At this time, the heating rod extends into the water bath ring to heat the external water source connected to the water bath ring. The water bath ring performs water bath heating on the glass reaction kettle. Copper oxide reaction reagents are introduced into the glass reaction kettle through an injection pipe. The stirring motor stirs the copper oxide reaction reagents through a stirring blade. At the same time, a PH sensor and a conductivity sensor arranged on the top of the glass reaction kettle obtain the reaction rate of copper oxide.

[0017] S2: After the oxidation cylinder reaction experiment is completed, the controller controls the driving assembly. The driving assembly drives the water bath ring to move downward. At the same time, it drives multiple heating rods to expand and move to directly above the collection ring through the expansion assembly. At the same time, the horizontal U-shaped rod in the expansion assembly drives the collection ring to move upward through the commutation assembly. The descaling ring on the collection ring passes through the heating rod, and the water scale attached to the surface of the heating rod is scraped off. The water scale is collected inside the collection ring.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. The structure of the present invention for water bath heating of a glass reactor is a water bath ring. A collection ring is sleeved on the outer wall of the water bath ring, and a driving component is arranged below the water bath ring. The driving component 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 it out of the water bath ring can quickly reduce the influence of the residual heat on the water bath temperature, prevent the residual heat of the heating rod from continuously heating 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 process. When the heating rod moves out of the water bath ring, overheating can be effectively prevented, reducing potential safety hazards caused by excessive temperature. Especially after the reaction ends, the automatic rod removal system can quickly prevent unnecessary heat accumulation.

[0020] 2. One of the core components of the driving component of the present invention is an expansion and support component. Since the collection ring is adjusted on the outer wall of the water bath ring, when the driving component drives the heating rod to move out of the water bath ring relative to the inside, a pure mechanical structure is used to drive multiple heating rods to move directly above the collection ring, waiting for the scale scraping component inside the collection ring to scrape the scale on the outer wall of the heating rod. On the one hand, the collection ring can automatically scrape and collect the scale. The combination of the collection ring and the scale scraping component makes the scale removal process automated. By driving the relative movement of the heating rod and the scale scraping component through a mechanical structure, manual operation is avoided, greatly improving the cleaning efficiency and accuracy, reducing manual intervention and operation risks. On the other hand, by scraping the scale in a timely and automatic manner, the long-term accumulation of scale on the surface of the heating rod is avoided. This not only improves the heating efficiency but also prevents damage to the heating rod by the scale, effectively extending the service life of the equipment. The scraping of the scale ensures direct contact between the surface of the heating rod and the water bath water source, maintaining the heating efficiency. Without the interference of scale, the heating rod can transfer heat more efficiently, improving the overall heating performance of the system.

[0021] 3. One of the core components of the driving component of the present invention is an expansion and support component, and a commutation component is arranged below the expansion and support component. When the driving component drives the heating rod to move out of the water bath ring relatively, the commutation component will drive the collection ring to move upward to connect with multiple heating rods. There is no need for multiple heating rods to move vertically, reducing the layout guiding pressure on the power cords of multiple heating rods in the entire device. Generally speaking, through the linkage design of the expansion and support component, the commutation component and the collection ring in the driving component, the program only needs to control one vertical cylinder throughout the process, reducing the complexity of the program and the maintenance difficulty of the equipment. Through automation and precise control, not only the cleaning efficiency and heat utilization efficiency of the heating rod are improved, but also manual operation is reduced, enhancing the overall safety, stability and economy of the equipment.

[0041] At the top of the glass reactor 11, an installation cylinder 13 is provided on the other side of the injection pipe 10. A PH sensor 131 and a conductivity sensor 132 are sequentially inserted into the installation cylinder 13 in the vertical direction.

[0043] A commutation component is arranged on the inner wall of the horizontal U-shaped rod 18, which drives the collection ring 20 to move upward and connect with the heating rod 29 when the horizontal U-shaped rod 18 moves downward. The commutation component includes a driving rack 21, a switching gear 22, and a driven rack 24. One side of the top of the glass reactor 11 is fixedly communicated with an injection pipe 10. A sealing cover 9 is screwed onto the top of the injection pipe 10. A stirring motor 8 is fixedly arranged at the middle position of the top of the glass reactor 11. The output end of the stirring motor 8 is fixedly provided with a vertical shaft 14. Stirring blades 141 are arranged at equal intervals along the vertical direction on the vertical shaft 14. The front view cross-sectional shape of the stirring blade 141 is U-shaped, which is used to assist in stirring the reaction materials in the inner cavity of the glass reactor 11.

[0044] Symmetrically and fixedly arranged at the bottom of the support plate 3 are vertical cylinders 19. The output ends of the vertical cylinders 19 pass through the support plate 3 and are fixedly provided with a horizontal U-shaped rod 18. The bottom side of the horizontal U-shaped rod 18 is fixedly connected to the side of the water bath ring 16. The collection ring 20 is sleeved on the outer wall of the water bath ring 16. Symmetrically and fixedly arranged on the outer wall of the collection ring 20 are driven rack bars 24. The side of the driven rack bar 24 is stably engaged with a switching gear 22. The other side of the switching gear 22 is stably engaged with a driving rack bar 21. The driving rack bar 21 is fixedly connected to the side of the horizontal U-shaped rod 18. The switching gear 22 is rotatably connected to the side of a support base 23. The bottom of the support base 23 is fixedly connected to the top of the support plate 3 by bolts. A descaling ring 30 is inserted into the collection ring 20 in the vertical direction. Circularly arrayed at the top of the descaling ring 30 are descaling holes 31. Symmetrically and fixedly connected to the bottom of the descaling ring 30 are inverted U-shaped rods 32 for supporting the descaling ring 30 inside the collection ring 20. The diameter of the descaling holes 31 is the same as the diameter of the heating rod 29.

[0045] The bottom of the inverted U-shaped rod 32 abuts against the inner cavity of the collection ring 20. The inside of the expansion cylinder 15 is hollow. The top of the expansion cylinder 15 is fixedly connected to a closed ring 17. Vertically arranged on the outer wall of the expansion cylinder 15 are a wide vertical surface 151, an inclined surface 152, and a narrow vertical surface 153 in sequence. The top side of the horizontal U-shaped rod 18 is fixedly connected to the side of the wide vertical surface 151. One end of the horizontal column 27, which is shaped like a hemisphere, contacts the wide vertical surface 151 or the inclined surface 152 or the narrow vertical surface 153 of the outer wall of the expansion cylinder 15.

[0046] The specific implementation steps and principles of the present invention are as follows:

[0047] In the initial state, at this time, the heating rod 29 extends into the water bath ring 16. The collection ring 20 is flush with the top of the water bath ring 16. One end of the horizontal column 27 contacts the side wall of the narrow vertical surface 153. At this time, the driving rack bar 21 is above the switching gear 22 and does not contact the switching gear 22. When conducting a copper oxide reaction experiment, the external water source connected to the water bath ring 16 is heated. The water bath ring 16 conducts water bath heating on the glass reaction kettle 11. The copper oxide reaction reagent is introduced into the glass reaction kettle 11 through the injection pipe 10. The stirring motor 8 agitates the copper oxide reaction reagent through the stirring blade 141. At the same time, the PH sensor 131 and the conductivity sensor 132 arranged on the top of the glass reaction kettle 11 obtain the copper oxide reaction rate.

[0048] After the oxidation cylinder reaction experiment ends, the controller 2 controls the vertical cylinder 19 to retract. The vertical cylinder 19 drives the water bath ring 16 to move downward. At the same time, it drives the expansion cylinder 15 to move downward through the horizontal U-shaped rod 18. During this process, the water bath ring 16 moves downward. When the horizontal column 27 reaches the top of the narrow vertical surface 153, the heating rod 29 moves out of the water bath ring 16. One end of the horizontal column 27 moves along the inclined surface 152, and multiple heating rods 29 move to the top of the collection ring 20. When the horizontal column 27 reaches the top of the inclined surface 152 and starts to contact the wide vertical surface 151, the multiple heating rods 29 stop moving away from each other. The driving rack 21 is above the switching gear 22 and contacts the switching gear 22, driving the collection ring 20 to move upward through the driven rack 24. The descaling ring 30 arranged inside the collection ring 20 passes through the multiple heating rods 29, and the scale that may exist outside the heating rod 29 is scraped off by the descaling holes 31.

[0049] When driving the multiple heating rods 29 to expand and move directly above the collection ring 20, at the same time, the horizontal U-shaped rod 18 in the expansion component drives the collection ring 20 to move upward through the commutation component. The descaling ring 30 on the collection 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 collection ring 20.

[0050] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
