Description

Technical Field

[0001] This utility model relates to the field of solution parameter measurement technology, and in particular to a solution Baume degree measuring device. Background Technology

[0002] Baumé degree is a parameter used to express the concentration and density of a solution. It is obtained by immersing a Baumé hydrometer in the solution being measured; the resulting reading is called the Baumé degree. The Baumé degree allows for rapid assessment of solution concentration. In industries such as petroleum, chemical, and food, the Baumé degree is widely used in industrial production, quality control, and scientific research. After measuring the Baumé degree of a solution, its mass percentage concentration can be found in a corresponding reference table. In industrial applications, it is commonly used to determine the concentration of solutions such as hydrochloric acid, sulfuric acid, and sodium hydroxide; in the food industry, the Baumé degree is also used for quality testing of honey.

[0003] In existing technologies, the solution to be tested needs to be sampled and analyzed separately before the Baumé hydrometer is immersed in the solution to obtain the Baumé degree. This process faces two problems: firstly, the media in the chemical production field are mostly hazardous chemicals or high-viscosity media, which may be volatile and unstable in the air; secondly, Baumé hydrometers are dedicated to different solutions, such as alcohol Baumé hydrometers and saline Baumé hydrometers, which have limitations in measuring the Baumé degree of mixed component solutions. Utility Model Content

[0004] The purpose of this invention is to provide a solution Baume degree measuring device that can directly measure the Baume degree of the solution under test online without sampling, and can measure both single and mixed component solutions.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model provides a device for measuring the Baumé degree of a solution, comprising:

[0007] The support tube has openings at both ends;

[0008] The flow tube is inserted into the support tube and runs from one end to the other. The two ends of the flow tube are connected to the openings at both ends of the support tube.

[0009] Vibration assembly, which is located inside the support pipe and connected to the flow pipe;

[0010] The detection unit is located on the support tube and connected to the flow tube. The detection unit includes a temperature sensor, a vibration sensor and a processor. The temperature sensor is used to monitor the temperature parameters of the solution flowing through the flow tube, the vibration sensor is used to monitor the vibration parameters of the flow tube, and the processor is used to receive the temperature parameters and vibration parameters and calculate the Baumé parameters.

[0011] Preferably, the support pipe is provided with connecting flanges at both ends.

[0012] Preferably, the flow tube includes a first flow tube and a second flow tube, and both ends of the support tube are provided with a distributor. The first flow tube and the second flow tube are connected to the openings at both ends of the support tube through the distributor.

[0018] Compared with the prior art, this utility model has significant progress:

[0019] This invention discloses a solution Baume degree measuring device. The solution flows into the opening of a support tube via a delivery pipe, then enters a flow tube, flows along the flow tube, and exits to the other end of the support tube.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0025] like Figures 1 to 2 The image shows an embodiment of the solution Baumé degree measuring device provided by this utility model.

[0026] See Figure 1 and Figure 2 The solution Baume degree measuring device in this embodiment includes a support tube 1, a flow tube 2, a vibration component 3, and a detection unit 4.

[0027] The support tube 1 serves as the basic support structure of the solution Baumé degree measuring device, providing a position for the installation and fixation of the flow tube 2, vibration assembly 3, and detection unit 4, and also supporting and protecting the internal flow tube 2 and vibration assembly 3. The support tube 1 has openings at both ends, allowing it to be connected to the pipeline conveying the solution to be tested during use. This ensures the solution can smoothly flow into and out of the solution Baumé degree measuring device, guaranteeing the continuity of the detection process.

[0028] The flow tube 2 is inserted into the support tube 1, extending from one end to the other. Both ends of the flow tube 2 are connected to the openings at both ends of the support tube 1. The flow tube 2 provides a channel for the flow of the solution, allowing the solution to enter the flow tube 2 from the opening of the support tube 1 and flow out from the other end of the flow tube 2, eventually continuing to flow through the opening at the other end of the support tube 1.

[0029] The vibration component 3 is located inside the support tube 1 and connected to the flow tube 2. The vibration component 3 causes the flow tube 2 to vibrate, providing a measurable vibration signal to the detection unit 4. The vibration component 3 is tightly connected to the flow tube 2, ensuring that the vibration can be stably transmitted from the vibration component 3 to the flow tube 2, thus ensuring the effective transmission of the vibration. At the same time, the vibration period, frequency, and other parameters will vary depending on the properties of the solution in the flow tube 2 (such as density, viscosity, etc.).

[0030] The detection unit 4 is mounted on the support tube 1 and connected to the flow tube 2. The detection unit 4 includes a temperature sensor, a vibration sensor, and a processor. The temperature sensor monitors the temperature parameters of the solution flowing through the flow tube 2, the vibration sensor monitors the vibration parameters of the flow tube 2, and the processor receives the temperature and vibration parameters and calculates the Baumé parameters. The main function of the temperature sensor is to monitor the temperature parameters of the solution flowing through the flow tube 2. Temperature significantly affects the physical properties of the solution, such as its density and viscosity. When the temperature increases, the density of the solution usually decreases, and these changes further affect the vibration characteristics of the flow tube 2. The main function of the vibration sensor is to monitor the vibration parameters of the flow tube 2, such as the vibration period and vibration frequency. The flow tube 2 vibrates under the action of the vibration component 3, and the vibration characteristics are affected by the properties of the solution flowing through it. For example, when the density of the solution changes, the vibration frequency of the flow tube 2 also changes accordingly. The vibration sensor can capture these changes in vibration parameters, providing data for subsequent Baumé calculations. The processor is the core component of the detection unit 4, and its main function is to receive signals from the temperature and vibration sensors. These signals contain information about the solution temperature and the vibration of the flow tube 2. The processor processes and analyzes these signals according to a pre-set algorithm and model, and finally calculates the Baumé parameter.

[0031] Therefore, in this embodiment of the solution Baume degree measuring device, the solution flows into the opening of the support tube 1 through the delivery pipe, then enters the flow tube 2, flows along the flow tube 2, and flows out to the other end of the support tube 1. The vibration component 3 drives the flow tube 2 to vibrate, the temperature sensor of the detection unit 4 monitors the solution temperature, and the vibration sensor captures the vibration parameters of the flow tube 2. The processor collects these data, analyzes them through algorithms and models, and finally calculates the Baume degree parameter. This achieves online real-time measurement of the solution Baume degree, effectively avoiding the risks associated with individual sampling of hazardous chemicals or high-viscosity, volatile, and unstable media in existing technologies, solving the problem of limited measurement of mixed component solutions, improving measurement efficiency, and ensuring measurement accuracy.

[0032] The Baumé degree is closely related to the physical properties of a solution, such as density and temperature. Therefore, the Baumé degree can be indirectly obtained through the density and temperature parameters of the solution. The working principle of the solution Baumé degree measuring device in this embodiment is as follows, specifically including:

[0033] ρ=K1·T 2 -K2 (1)

[0034] In equation (1), ρ is the solution density, T is the vibration period, and K1 and K2 are constants.

[0035] When the density of the solution is less than that of water, °Bé=140 / SG-130 (2)

[0036] When the density of the solution is greater than that of water, °Bé=145-145 / SG (3)

[0037] In equations (2) and (3), °Bé is the Baumé degree, and SG is the ratio of the solution density to the density of pure water at the same temperature.

[0038] For a solution containing a mixed medium, when the solution flows stably through the flow tube 2, the temperature sensor monitors the temperature parameters of the solution flowing through the flow tube 2. The processor outputs a drive signal to the vibration component 3, which drives the flow tube 2 to vibrate. The vibration sensor monitors the vibration period of the flow tube 2 and then sends the monitored vibration period parameters to the processor. The processor calculates the density of the solution according to the above formula (1), and the calculated solution density corresponds to the density at that temperature monitored by the temperature sensor. The processor then compares the calculated solution density with the density of pure water to obtain SG. When the solution density is less than the density of water, SG is substituted into formula (2) to calculate the Baumé degree; when the solution density is greater than the density of water, SG is substituted into formula (3) to calculate the Baumé degree. It is worth noting that the Baumé degree should generally be measured at a solution temperature of 15.6℃, but in actual measurement, the solution temperature will generally not exactly meet the standard. Therefore, the results obtained from formulas (2) and (3) need to be further corrected. Specifically, for every 1 degree difference in temperature, the Baumé degree differs by 0.054 degrees. When the solution temperature monitored by the temperature sensor is higher than 15.6℃, the processor adds the difference in Baumé degree to the result calculated by equation (2) or equation (3). When the solution temperature monitored by the temperature sensor is lower than 15.6℃, the processor subtracts the difference in Baumé degree from the result calculated by equation (2) or equation (3), thereby obtaining the final Baumé degree.

[0039] For solutions of a single medium, extensive experiments have yielded Baumé values ​​at different temperatures and densities in practical applications, demonstrating a correlation between solution density, temperature, and Baumé value. The Baumé value, density, and temperature data of single-medium solutions already measured in practical applications are input and stored in the solution Baumé measurement device of this embodiment. When the solution flows through flow tube 2, the device first measures the solution's composition, temperature, and density. Then, based on the stored data, it identifies and displays the Baumé value corresponding to the solution's composition at the measured temperature and density, thereby making the measured Baumé value more accurate.

[0040] See Figure 1 and Figure 2Preferably, the support pipe 1 is provided with connecting flanges 11 at both ends. The connecting flanges 11 provide a standardized connection method, enabling the support pipe 1 to be quickly and conveniently connected to the pipeline system that transports the solution to be tested. The installation of the device can be completed simply by aligning the flange with the corresponding pipeline flange and fixing it with bolts, without the need for complicated welding or special connection processes, which greatly simplifies the installation process and improves installation efficiency.

[0041] See Figure 1 and Figure 2 Preferably, the flow tube 2 includes a first flow tube 21 and a second flow tube 22. Both ends of the support tube 1 are provided with distributors 12. The first flow tube 21 and the second flow tube 22 are connected to the openings at both ends of the support tube 1 through the distributors 12. After the support tube 1 is connected to the solution delivery pipeline, the solution in the delivery pipeline flows from the opening of the support tube 1 through the distributors 12 to the first flow tube 21 and the second flow tube 22. The distributors 12 can evenly distribute the solution to the first flow tube 21 and the second flow tube 22, avoiding measurement deviations caused by uneven distribution of the solution in the first and second flow tubes 21 and 22, thus improving the reliability and accuracy of the measurement results.

[0042] See Figure 1 and Figure 2 Preferably, the vibration component 3 includes a coil 31 and a magnet 32. The coil 31 is disposed in the first flow tube 21, and the magnet 32 ​​is disposed in the second flow tube 22, with the coil 31 and magnet 32 ​​correspondingly arranged. When an alternating current passes through the coil 31, the coil 31 generates an alternating magnetic field. Due to the interaction between the magnetic field of the magnet 32 ​​and the magnetic field generated by the coil 31, the first flow tube 21 and the second flow tube 22 are subjected to an electromagnetic force. This electromagnetic force causes the first flow tube 21 and the second flow tube 22 to vibrate synchronously at their natural frequencies. Simultaneously, the vibration frequencies of the first flow tube 21 and the second flow tube 22 change due to variations in the solution density, thereby enabling the measurement of the solution density. Combined with data from a temperature sensor, the processor can calculate the Baumé degree in real time, providing continuous monitoring functionality. This electromagnetic drive method eliminates the need for complex mechanical structures, reducing maintenance costs and failure risks, and improving measurement stability and accuracy.

[0043] See Figure 1 and Figure 2Preferably, the vibration assembly 3 has at least two sets and is spaced apart along the axial direction of the flow tube 2. In this embodiment, three sets of coils 31 and magnets 32 are provided, one set of coils 31 and magnets 32 is located in the middle section of the first flow tube 21 and the second flow tube 22, and the other two sets of coils 31 and magnets 32 are symmetrically arranged near the ends of the first flow tube 21 and the second flow tube 22. The electromagnetic force generated by the multiple sets of coils 31 and magnets 32 acts on different positions of the first flow tube 21 and the second flow tube 22, so that the first flow tube 21 and the second flow tube 22 are subjected to force at multiple points along their radial direction, thereby achieving more uniform synchronous vibration. This multi-point driving method can reduce the non-uniformity and distortion of vibration, and improve the stability and consistency of vibration.

[0044] See Figure 1 and Figure 2 Preferably, damping plates 5 are connected to both ends of the flow tube 2. When the flow tube 2 vibrates, the damping plates 5 also undergo elastic deformation, which effectively prevents the vibration of the flow tube 2 from being transmitted to the outside, and also blocks external vibrations, avoiding interference from external vibrations on the flow tube 2. This ensures that the vibration sensor accurately monitors the vibration period of the flow tube 2, guaranteeing high accuracy and high sensitivity of the measurement.

[0045] See Figure 1 and Figure 2 Preferably, the detection unit 4 is equipped with a display screen 41 for displaying the Baumé degree parameter. After the processor of the detection unit 4 completes the Baumé degree calculation, it transmits the result to the display screen 41. The display screen 41 presents the Baumé degree parameter in real time and intuitively, providing on-site operators with direct measurement results without the need to obtain data through other devices, thus improving the convenience and efficiency of operation. In addition to displaying the Baumé degree parameter, the display screen 41 can also display other related parameters, such as the temperature of the solution monitored by a temperature sensor.
