Description

Technical Field

[0001] This utility model relates to the field of chemical reaction technology, and more specifically, to a transparent multifunctional chemical reaction device. Background Technology

[0002] Chemical experiments are a crucial cornerstone of the development of chemistry. By designing reasonable experimental schemes and utilizing various experimental instruments and reagents, specific conditions are artificially created to induce chemical reactions in substances, thereby exploring the composition, structure, properties, and laws governing changes in matter. In the process of chemical experiments, the chemical reaction apparatus plays a central role, providing the site for the reaction. Different reactions often require different functional apparatuses to meet needs such as controlling reaction conditions (temperature, pressure, reactant concentration, etc.), observing reaction phenomena, and collecting reaction products. These apparatuses are the key guarantee for the smooth conduct of chemical experiments and the acquisition of accurate experimental results.

[0003] However, existing chemical reaction apparatuses, such as those commonly used for experiments exploring molecular motion, are mostly structurally and functionally limited. For instance, in experiments involving color changes caused by molecular motion, the apparatus often only provides basic reaction space. To simultaneously monitor parameters of the reaction system (such as pH value) in real time, additional external monitoring instruments are required, which is cumbersome and prone to interfering with the reaction system. Furthermore, when it is necessary to add chemical materials in batches to precisely control the reaction, it mostly relies on manual operation by the experimenter. This not only makes it difficult to guarantee the accuracy and timeliness of the addition, but also fails to automatically add chemical materials when the monitoring value indicates that the reaction is insufficient and chemical materials need to be added, seriously affecting the efficiency of the experiment and the accuracy of the results.

[0017] Please see Figures 1-4 The system includes a base 1, on the upper surface of which a transparent reaction chamber 5 and four container boxes 15 are fixedly connected. An infrared temperature sensor 18, a humidity sensor 17, a fluorescent dissolved oxygen sensor 20, an electromagnetic conductivity sensor 22, and a glass electrode pH sensor 21 are fixedly connected to the inner left wall of the transparent reaction chamber 5. A peristaltic pump 19 is fixedly connected to the upper surface of the base 1 in front of each container box 15. The output end of each peristaltic pump 19 is fixedly connected to a flow tube 25, and the outer surface of each flow tube 25 is fixedly connected to... A one-way valve 24 is provided. A heating groove 28 is provided at the bottom front of the transparent reaction box 5. A heat insulation plate 3 is snapped into the inside of the heating groove 28. A heating wire 29 is fixedly connected to the back of the heat insulation plate 3. An exhaust pipe 10 is fixedly connected to the upper surface of the transparent reaction box 5. A pressure reducing valve 9 is fixedly connected to the outer surface of the exhaust pipe 10. A conical feeding pipe 7 is fixedly connected to the upper surface of the transparent reaction box 5. A sealing cap 8 is snapped into the inside of the conical feeding pipe 7. A controller 2 is fixedly connected to the left side of the transparent reaction box 5. A rubber injection plug 16 is fixedly connected to the left side of the transparent reaction box 5.

[0018] Specifically, the base 1 provides installation support for the transparent reaction chamber 5 and four container boxes 15. The transparent reaction chamber 5 serves as the main reaction site. The infrared temperature sensor 18, humidity sensor 17, fluorescent dissolved oxygen sensor 20, electromagnetic induction conductivity sensor 22, and glass electrode pH sensor 21 on its left inner wall can collect reaction parameters in real time. The peristaltic pump 19 on the base 1 connects the container box 15 to the transparent reaction chamber 5 through the flow pipe 25. The one-way valve 24 prevents the reaction liquid from flowing back and contaminating the materials in the container box 15. The heat insulation plate 3 in the heating tank 28, together with the heating wire 29, can adjust the reaction temperature. The exhaust pipe 10 and the pressure reducing valve 9 balance the air pressure in the transparent reaction chamber 5. The conical feed pipe 7 facilitates the addition of initial materials, and the sealing cap 8 ensures airtightness. The controller 2 can integrate control. The rubber injection stopper 16 facilitates temporary replenishment of reagents. This solves the problem of existing devices requiring external monitoring instruments and manual material addition, and realizes real-time monitoring of reaction parameters and precise material delivery.

[0019] Please see Figures 1-4 Four container boxes 15 are located at the rear of the transparent reaction box 5. The infrared temperature sensor 18 and humidity sensor 17 are located above the transparent reaction box 5. The electromagnetic induction conductivity sensor 22 and glass electrode pH sensor 21 are located in the lower middle of the transparent reaction box 5. The fluorescent dissolved oxygen sensor 20 is located in the middle of the transparent reaction box 5. The input end of each peristaltic pump 19 extends into the interior of the container box 15. The end of each flow tube 25 away from the peristaltic pump 19 extends into the interior of the transparent reaction box 5. The controller 2 is electrically connected to the infrared temperature sensor 18, humidity sensor 17, fluorescent dissolved oxygen sensor 20, electromagnetic induction conductivity sensor 22, glass electrode pH sensor 21, peristaltic pump 19 and heating wire 29 respectively through wires. An auxiliary handle 4 is fixedly connected to the front of the heat insulation plate 3.

[0020] Specifically, four container boxes 15 are located behind the transparent reaction box 5, which makes reasonable use of space and avoids interference with reaction observation. The infrared temperature sensor 18 and humidity sensor 17 are placed above the transparent reaction box 5 to accurately monitor reaction environment parameters. The electromagnetic induction conductivity sensor 22 and glass electrode pH sensor 21 are located in the lower middle, and the fluorescent dissolved oxygen sensor 20 is located in the middle, which can specifically monitor key parameters of the reaction solution. The peristaltic pump 19 has its input end passing through the container box 15 and its output end passing through the flow pipe 25 into the transparent reaction box 5 to ensure smooth material delivery. The controller 2 is electrically connected to each sensor, the peristaltic pump 19 and the heating wire 29 through wires to realize parameter acquisition and equipment linkage control. The auxiliary handle 4 facilitates the installation and removal of the heat insulation plate 3, further improving the ease of operation of the device and the accuracy of parameter monitoring, and solving the problems of incomplete parameter monitoring and non-linked control in the existing device.

[0021] Please see Figures 1-4A placement rack 11 is fixedly connected to the upper surface of the transparent reaction chamber 5. Multiple chemical containers 13 are snapped into the inside of the placement rack 11. An auxiliary nameplate 12 is fixedly connected to the upper surface of the placement rack 11 in front of each chemical container 13. Four indicator lights 6 are fixedly connected to the upper surface of the transparent reaction chamber 5. Each indicator light 6 is electrically connected to the controller 2 through a wire.

[0022] Specifically, the rack 11 on the transparent reaction chamber 5 is used to hold and store chemical containers 13. The auxiliary nameplate 12 can mark the reagent information in the chemical containers 13 to avoid reagent confusion. The four indicator lights 6 are connected to the controller 2 through wires. When the sensor detects abnormal parameters, the controller 2 can trigger the corresponding indicator light 6 to light up, so as to remind the experimenter to pay attention to the reaction status in time. This solves the problem of messy reagent storage and difficulty in timely detection of abnormal status in the existing device, and improves the standardization and safety of experimental operation.

[0023] Please see Figures 1-4 Each container 15 has an injection pipe 14 and an discharge pipe 26 fixedly connected to its upper and back surfaces, and a cleaning pipe 23 fixedly connected to the right side of the bottom of the transparent reaction box 5.

[0024] Specifically, the injection tube 14 on the container 15 facilitates the replenishment of chemical materials into the container 15, and the discharge tube 26 facilitates the emptying of residual materials in the container 15. The cleaning tube 23 at the bottom of the transparent reaction box 5 can discharge waste liquid and residue after the experiment. Material replenishment and waste liquid cleaning can be completed without disassembling the device.

[0025] Please see Figures 1-4 A snap-fit ​​plate 27 is fixedly connected to the back of the transparent reaction chamber 5. The inside of the snap-fit ​​plate 27 is snapped into the outer surface of the four one-way valves 24.

[0026] Specifically, the snap-fit ​​plate 27 on the back of the transparent reaction box 5 fixes the four one-way valves 24 to prevent the flow pipe 25 from shifting due to the weight of the one-way valves 24 or the flow of liquid, thus ensuring the connection stability of the flow pipe 25 and preventing material delivery deviation or leakage due to pipe shaking.

[0027] Working principle: In use, the initial reaction material is first added through the conical feed pipe 7 on the transparent reaction chamber 5. The sealing cap 8 is then tightened to ensure the reaction system is sealed. The base 1 provides stable support for the transparent reaction chamber 5 and the four container boxes 15. The container boxes 15 are used to store the chemical materials to be added. The infrared temperature sensor 18, humidity sensor 17, fluorescent dissolved oxygen sensor 20, electromagnetic induction conductivity sensor 22, and glass electrode pH sensor 21 on the left inner wall of the transparent reaction chamber 5 collect real-time data on reaction temperature, ambient humidity, dissolved oxygen, and conductivity from different locations. These sensors transmit parameter signals to controller 2 via wires, including pH value parameters. Controller 2 analyzes the parameters and, when abnormal reaction parameters or insufficient reaction requiring additional materials are detected, it activates the peristaltic pump 19 in front of the corresponding container 15 on base 1. The peristaltic pump 19 draws chemical materials from container 15 through its input end and delivers them to the transparent reaction chamber 5 via the flow pipe 25 connected to its output end. The one-way valve 24 on the flow pipe 25 prevents the reaction liquid in the transparent reaction chamber 5 from flowing back and contaminating the materials in container 15. If the reaction requires temperature adjustment, controller 2 can control... The heating wire 29 on the back of the heat insulation plate 3 inside the heating groove 28 at the bottom front of the transparent reaction chamber 5 operates to control the reaction temperature. The gas generated during the reaction is discharged through the exhaust pipe 10 on the transparent reaction chamber 5. The pressure reducing valve 9 on the exhaust pipe 10 balances the gas pressure inside the chamber to prevent excessive pressure. If a small amount of reagent needs to be added temporarily during the experiment, it can be injected through the rubber injection plug 16 on the left side of the transparent reaction chamber 5. The chemical container 13 in the shelf 11 on the upper surface of the transparent reaction chamber 5 can store auxiliary reagents. The auxiliary nameplate 12 marks the reagent information to avoid confusion. When the sensor detects abnormal parameters, the controller 2 will also trigger the corresponding indicator light 6 to light up to remind the experimenter. After the experiment, the residual material is emptied through the discharge pipe 26 on the container box 15, and the waste liquid and residue are discharged through the cleaning pipe 23 at the bottom of the transparent reaction chamber 5. The snap-fit ​​plate 27 on the back of the transparent reaction chamber 5 fixes the one-way valve 24 to ensure the stable connection of the flow pipe 25. Thus, the complete effect from the initial preparation of the reaction, real-time monitoring of parameters, automatic replenishment of materials, temperature control to post-experiment cleaning is achieved, solving the problems of the single function and cumbersome operation of the existing device, and ensuring that the experiment is carried out efficiently and accurately.
