Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a real-time material color detection device for reaction vessels. Background Technology

[0002] In process industries such as chemical, pharmaceutical, and food processing, reaction vessels are the core equipment for material mixing, reaction, and synthesis. During a synthesis reaction, parameters such as the pH value, color, and temperature of the mixture will change. These changes indicate the progress of the reaction to some extent, so monitoring these indicators allows for monitoring the state of the reaction.

[0003] Currently, color monitoring during material mixing and reaction is mostly done by operators through direct observation via a viewing window on the reactor. This relies on personnel experience, lacks judgment standards, and the viewing window is easily contaminated by materials, affecting the observation effect and failing to effectively monitor the reaction process. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, which mostly rely on operators to directly observe through a viewing window, depend on personnel experience, lack judgment standards, and have viewing windows that are easily contaminated by materials, affecting the observation effect and failing to effectively monitor the reaction process. Therefore, this invention proposes a real-time material color detection device for reaction vessels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A real-time material color detection device for a reaction vessel includes a reaction vessel, on which a sampling port and a reflux port are provided and respectively connected to a sampling pipeline and a reflux pipeline;

[0007] A color recognition device is provided between the sampling pipeline and the return pipeline. The sampling pipeline is equipped with a sampling valve and a diaphragm pump, and the return pipeline is equipped with a return valve.

[0008] The sampling pipeline is connected to a flushing pipeline, and the other end of the flushing pipeline is connected to a flushing water supply device. The flushing pipeline has a first branch and a second branch, each equipped with a flushing valve. The first branch and the second branch are respectively connected before and after the diaphragm pump.

[0009] Preferably, the sampling pipeline is provided with an observation window.

[0010] Preferably, an observation window is provided on the return pipeline.

[0011] Preferably, the sampling port is located at the bottom of the reactor.

[0012] Preferably, the sampling valve, diaphragm pump, reflux valve, color recognition device, and flushing valve are all electrically connected to the control box, which contains a PLC controller.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the material is extracted from the bottom of the reactor by a diaphragm pump for color identification, which can ensure the accuracy of the judgment of the material state and the effect of color identification. At the same time, the operator can directly observe the color through the observation window, which facilitates the use of the detection device.

[0015] 2. In this utility model, the flushing pipeline is designed to flush the pipeline before and after the pump separately, so as to avoid solid materials from accumulating and abrading the diaphragm pump during flushing, and also to improve the cleaning effect of the color recognition device and ensure the accuracy of color recognition.

[0016] This utility model has a simple structure and reasonable design, which can realize continuous identification of the color of materials in the reaction vessel and ensure the accuracy of identification. It can also ensure the accuracy of judging the reaction process. It is easy to use and suitable for promotion. Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the overall structure of this utility model.

[0018] In the diagram: Reactor 1, Sampling port 11, Reflux port 12, Sampling pipeline 2, Sampling valve 21, Diaphragm pump 22, Reflux pipeline 3, Reflux valve 31, Observation window 32, Color recognition device 4, Flushing pipeline 5, First branch 51, Second branch 52, Flushing valve 53, Control box 6. Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1 A real-time material color detection device for a reaction vessel includes a reaction vessel 1. A sampling port 11 and a reflux port 12 are provided through the reaction vessel 1 and are respectively connected to a sampling pipeline 2 and a reflux pipeline 3. Material is extracted through the sampling port 11, passes through the sampling pipeline 2 and the reflux pipeline 3, and then returns to the reaction vessel 1 through the reflux port 12, realizing the cyclic detection of material color.

[0021] A color recognition device 4 is provided between the sampling pipeline 2 and the return pipeline 3. The sampling pipeline 2 is equipped with a sampling valve 21 and a diaphragm pump 22, and the return pipeline 3 is equipped with a return valve 31. The diaphragm pump 22 is used to extract materials for material circulation monitoring.

[0022] The sampling pipeline 2 is connected to a flushing pipeline 5, the other end of which is connected to a flushing water supply device. The flushing pipeline 5 has a first branch 51 and a second branch 52, each equipped with a flushing valve 53. The first branch and the second branch are connected before and after the diaphragm pump 22, respectively. The pipelines before and after the pump are cleaned separately through the first branch 51 and the second branch 52. Since the materials are mostly solid-liquid mixtures, there may be solid material deposits in the pipeline before the pump. Segmented flushing ensures the flushing effect and also facilitates separate flushing of the pipeline before the pump, allowing for targeted flushing to prevent blockages caused by solid material deposits.

[0023] Based on the above technical solution, when the reactor is running, the diaphragm pump 22 is started to extract material from the sampling port 11, and the material is sent to the color recognition device 4 through the sampling pipeline 2 to perform real-time color recognition and detection. After detection, the material is sent back to the reactor 1 through the return pipeline 3.

[0024] When flushing the pipeline is required, first flush the pipeline before the pump: open the flushing valve 53 and sampling valve 21 on the first branch 51, close the diaphragm pump 22, return valve 31 and flushing valve 53 on the second branch, and flush the sampling pipeline 2 before the pump; then flush the pipeline after the pump: close the flushing valve 53 on the first branch 51, diaphragm pump 22 and sampling valve 21, open the return valve 31 and flushing valve 53 on the second branch 52, and flush the sampling pipeline 2 and return pipeline 3 after the pump; finally flush the diaphragm pump 22 and the pipeline after the pump: open the flushing valve 53 on the first branch 51, diaphragm pump 22 and return valve 31, close the sampling valve 21 and flushing valve 53 on the second branch, and flush the diaphragm pump 22 and the pipeline after the pump. By flushing the downstream pipeline and the diaphragm pump 22 sequentially, the accumulation of solid materials during flushing is prevented from aggravating the wear of the color recognition device 4, thus protecting the detection window of the color recognition device 4.

[0025] The step-by-step flushing design of the pre-pump pipeline, post-pump pipeline, and diaphragm pump effectively flushes out solid materials deposited in the pre-pump pipeline, preventing excessive solid particles from causing wear on the diaphragm pump chamber and protecting its sealing performance. It also prevents excessive solid materials from entering the color recognition device 4, ensuring a clean and uncontaminated detection window, thus guaranteeing the accuracy of color recognition and extending the device's lifespan.

[0026] In this technical solution, such as Figure 1 As shown, observation windows 32 can be provided on the sampling pipeline 2 and the return pipeline 3. This allows operators to directly observe the color of the sampled material, facilitates on-site personnel to directly judge the synthesis process, and assists in the control of the reaction process.

[0027] In this technical solution, such as Figure 1As shown, the sampling port 11 is located at the bottom of the reactor 1. Bottom sampling does not require interruption of the reaction, facilitating continuous monitoring during production. When solid-liquid mixtures are being mixed, solid materials may settle at the bottom. Bottom sampling can more accurately reflect the actual proportions of each component in the reaction system, allowing for a more accurate determination of whether the reaction is complete and ensuring the accuracy of the color recognition device 4 in judging the reaction progress.

[0028] In this technical solution, such as Figure 1 As shown, the sampling valve 21, diaphragm pump 22, reflux valve 31, color recognition device 4, and flushing valve 53 are all electrically connected to the control box 6, which contains a PLC controller. The control box 6 provides overall control of the detection device and facilitates the color recognition device 4 in recording the colors of the identified materials, thus forming a material color database and improving the accuracy of reaction effect judgment.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
