Description

Technical Field

[0001] This application relates to the field of industrial process measurement and control technology, and in particular to a liquid level detection device for high-temperature conductive media (such as molten glass), specifically a probe-detachable liquid level detection device. Background Technology

[0002] In industrial automation and process control, accurate liquid level monitoring is crucial for ensuring production efficiency and product quality, especially in industrial environments involving high temperatures, corrosive media, or conductive media, such as liquid level measurement in glass furnaces. Under these extreme conditions, traditional liquid level measurement techniques often struggle to provide stable and accurate results. These environments place stringent demands on the stability, accuracy, and durability of measuring equipment. For example, liquid level measurement in glass furnaces is critical for controlling the temperature and composition of molten glass, directly impacting the quality of the final product. However, high-temperature environments present challenges to the materials and design of measuring equipment, while corrosive or conductive media can interfere with measurement signals, leading to inaccurate data.

[0003] Currently, liquid level measurement equipment typically employs a fixed probe design. When these probes wear out or become damaged, the entire probe system often needs to be replaced. In high-temperature environments such as glass furnaces, traditional liquid level probes are susceptible to corrosion due to prolonged contact with molten glass, requiring frequent replacement. However, the design of traditional probes necessitates disassembling the entire probe system, including the support structure and measuring elements, during replacement. This not only increases maintenance difficulty but can also lead to production interruptions, impacting production continuity and economic efficiency. Furthermore, each replacement requires professional personnel, increasing labor costs and safety risks. Due to the non-removable nature of the probes, the entire measuring equipment may become unusable due to the failure of a single component, further increasing maintenance costs and reducing production efficiency.

[0004] Therefore, in order to solve the problems in the existing technology, especially to improve the maintenance efficiency and reduce the maintenance cost of liquid level measurement, there is an urgent need for a new type of probe-designed liquid level detection device. The device should be designed so that when the probe is damaged, only the damaged part is replaced, instead of replacing the entire probe, thereby reducing maintenance time and cost and improving production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a liquid level detection device with a detachable probe, so as to overcome the shortcomings of the existing liquid level detection device, which requires the entire detection part of the liquid level gauge to be replaced when the probe is replaced.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A probe-detachable liquid level detection device includes:

[0008] The liquid level gauge is connected to a probe via an output shaft. The liquid level gauge serves as the control and data processing center of the liquid level detection device, receiving and processing liquid level measurement data.

[0009] The output shaft is connected to the liquid level gauge at one end and to the probe at the other end. It connects the liquid level gauge and the probe and drives the probe to move up and down to achieve precise positioning of the probe and liquid level measurement.

[0010] The probe, as a sensing component for liquid level measurement, directly contacts the liquid surface and measures the liquid level height. The probe includes a detachable needle and a probe connecting rod. The detachable needle serves as the front end of the probe and directly contacts the liquid surface. The probe connecting rod serves as the main body of the probe, supporting the detachable needle and transmitting motion. The upper end of the probe connecting rod is connected to the output shaft, and the lower end is detachably connected to the detachable needle via a connecting assembly. The connecting assembly enables quick disassembly and installation of the detachable needle on the probe connecting rod.

[0011] Both the upper end of the detachable needle and the lower end of the probe connecting rod have through holes. The connecting assembly enables quick disassembly and installation of the detachable needle and the probe connecting rod through the through holes, facilitating maintenance and replacement.

[0012] The connecting assembly includes a bolt and a nut. The bolt passes through a through hole at the upper end of the detachable needle and the lower end of the probe connecting rod and is connected to the nut to achieve a detachable connection between the detachable needle and the probe connecting rod. This design allows for a secure connection between the detachable needle and the probe connecting rod while maintaining detachability.

[0013] A gasket is placed between the nut and the probe to provide cushioning and protection, improving the sealing and stability of the connection, reducing wear, and protecting the probe connecting rod.

[0014] The nut is a U-shaped self-locking nut, which provides additional locking force, increases the security of the connection, prevents the nut from loosening, and ensures the stability of the probe during the measurement process.

[0015] The output shaft is L-shaped, which allows the probe to measure more flexibly on the side of the liquid level gauge, adapting to different installation environments and space constraints. The shorter end of the output shaft is connected to the liquid level gauge, and the other end is connected to the probe.

[0016] The liquid level gauge is connected to the output shaft via a servo motor. The servo motor controls the movement of the output shaft, thereby realizing the axial movement of the probe, accurately controlling the position of the probe, realizing liquid level measurement, and allowing the probe to contact and measure the liquid surface.

[0017] The liquid level gauge is fixed on the bracket, which ensures the stability of the entire liquid level detection device and facilitates installation at different measurement positions.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects:

[0019] This invention provides a liquid level detection device with a detachable probe. Through the detachable probe design, especially the detachable needle, it is possible to replace only the damaged part when the probe is damaged or worn, rather than the entire detection system, thereby significantly reducing maintenance costs and time and improving production continuity.

[0020] By introducing a quick-release mechanism using bolts, nuts, and washers, the probe can be quickly disassembled and installed, simplifying the maintenance process and reducing production interruptions. The use of a U-shaped self-locking nut enhances the stability of the probe connection, ensuring reliable operation in high-temperature and corrosive environments. Precise control of the servo motor enables accurate movement of the output shaft, ensuring accurate liquid level measurement and improving measurement accuracy.

[0021] The liquid level gauge is fixed with a bracket for easy installation and adjustment, adapting to various production conditions. The user interface design allows operators to easily set up and adjust the system, improving operational convenience. The probe's durability is enhanced by a detachable needle design, extending the device's lifespan. The L-shaped output shaft design provides greater flexibility, allowing the probe to adapt to different installation environments and space constraints.

[0022] Furthermore, the device of this application can quickly stop the movement of the probe through a rapid release mechanism in emergency situations, enhancing operational safety. Overall, the liquid level detection device of this application, with its innovative structural design, provides a more economical, efficient, accurate, and easy-to-maintain solution for liquid level measurement in high-temperature, corrosive, or conductive media environments, effectively overcoming the shortcomings of existing technologies.

[0030] Example:

[0031] like Figures 1 to 2 As shown, a probe-detachable liquid level detection device is provided in a specific embodiment of this utility model, comprising:

[0032] The liquid level gauge 6 is connected to the probe 8 via the output shaft 7. The liquid level gauge 6 serves as the control and data processing center of the liquid level detection device, receiving liquid level measurement data and processing the liquid level measurement data.

[0033] The output shaft 7 is connected to the liquid level gauge 6 at one end and to the probe 8 at the other end. It connects the liquid level gauge 6 and the probe 8 and drives the probe to move up and down to achieve precise positioning of the probe and liquid level measurement.

[0034] The probe 8, as a sensing component for liquid level measurement, directly contacts the liquid surface and measures the liquid level height. The probe 8 includes a detachable needle 4 and a probe connecting rod 9. The detachable needle 4 serves as the front end of the probe 8 and directly contacts the liquid surface. The probe connecting rod 9 serves as the main body of the probe 8, supporting the detachable needle and transmitting motion. The upper end of the probe connecting rod 9 is connected to the output shaft 7, and the lower end is detachably connected to the detachable needle 4 via a connecting assembly. The connecting assembly enables quick disassembly and installation of the detachable needle 4 on the probe connecting rod 9.

[0035] The upper end of the detachable needle 4 and the lower end of the probe connecting rod 9 are both provided with through holes. The connecting assembly enables quick disassembly and installation of the detachable needle 4 and the probe connecting rod 9 through the through holes, facilitating maintenance and replacement.

[0036] The connecting assembly includes a bolt 1 and a nut 3. The bolt 1 passes through a through hole at the upper end of the detachable needle 4 and the lower end of the probe connecting rod 9 and is connected to the nut 3, thereby realizing the detachable connection between the detachable needle 4 and the probe connecting rod 9. This design allows for a stable connection between the detachable needle 4 and the probe connecting rod 9 while maintaining detachability.

[0037] A gasket 2 is placed between the nut 3 and the probe 8 to provide cushioning and protection between the nut 3 and the probe 8, thereby improving the sealing and stability of the connection, reducing wear, and protecting the probe connecting rod 9.

[0038] The nut 3 is a U-shaped self-locking nut, which provides additional locking force, increases the safety of the connection, prevents the nut 3 from loosening, and ensures the stability of the probe 8 during the measurement process.

[0039] The output shaft 7 is L-shaped, which allows the probe to measure more flexibly on the side of the liquid level gauge, adapting to different installation environments and space constraints. The shorter end of the output shaft 7 is connected to the liquid level gauge 6, and the other end is connected to the probe 8.

[0040] The liquid level gauge 6 is connected to the output shaft 7 via a servo motor. The servo motor controls the movement of the output shaft 7, thereby realizing the axial movement of the probe 8, accurately controlling the position of the probe 8, realizing liquid level measurement, and allowing the probe 8 to contact and measure the liquid surface.

[0041] The liquid level gauge 6 is fixed on the bracket 5, which ensures the stability of the entire liquid level detection device and facilitates installation at different measurement positions.

[0042] In this specific embodiment, the liquid level gauge 6 is a MAX-50B model. This model of glass liquid level gauge (glass liquid level height measuring instrument) is used to measure the height of molten glass (it can also measure the liquid level of other conductive media, material levels). It can not only measure the glass liquid level, but also measure the levels of other materials that cannot be accurately measured using conventional differential pressure, ultrasonic, radar, or radio frequency methods, or that require high accuracy, reliable measurement, and good repeatability. When using the detachable probe and liquid level detection device described in this specific embodiment, the liquid level gauge 6 is first securely installed on one side of the glass furnace using the bracket 5. The servo motor inside the liquid level gauge 6 precisely controls the movement of the output shaft 7. One end of the output shaft 7 is connected to the liquid level gauge 6, and the other end is connected to the probe 8. The probe 8 includes a detachable needle 4. This design allows for quick and convenient replacement of the needle 4 when it wears or is damaged due to prolonged contact with high-temperature molten glass.

[0043] When needle 4 needs to be replaced, the operator can easily remove nut 3 and washer 2, and then remove needle 4 from probe connecting rod 9 using bolt 1. This process does not require disassembling the entire probe 8 or level gauge 6, greatly shortening maintenance time and reducing maintenance costs. After replacing needle 4, the operator can quickly reinstall nut 3 and tighten it to ensure the stability of probe 8 and the accuracy of measurement.

[0044] During operation, the servo motor drives the output shaft 7 to lower the probe 8 to the surface of the molten glass in the furnace. The needle 4 of the probe 8 contacts the surface of the molten glass, converting the liquid level signal into an electrical signal and transmitting it to the liquid level gauge 6. The liquid level gauge 6 processes these signals, calculates the liquid level height, and outputs the data through a display unit or communication interface for the operator to monitor.

[0045] Furthermore, the user interface of the level gauge 6 allows operators to configure or adjust the system as needed to adapt to different production conditions. The overall design of the device not only improves the accuracy of level measurement but also enhances ease of operation and economical maintenance, making it an ideal choice for level monitoring in glass manufacturing processes. In particular, the ability to quickly replace the damaged needle 4 significantly improves the reliability of the device and the continuity of the production process.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
