Description

Technical Field

[0001] This utility model relates to the field of measuring instrument protection technology, and in particular to an electromagnetic flowmeter with a protective structure. Background Technology

[0002] In modern industrial production, accurate measurement of fluid flow rate is a key link in ensuring stable and efficient operation of the production process and product quality control. The environmental conditions of industrial production sites are often very complex and harsh. Traditional electromagnetic flow meters are easily affected by external factors in complex industrial environments, which leads to a decrease in measurement accuracy. Due to insufficient protection performance, the failure rate is high in complex industrial environments. Frequent failures lead to a significant increase in equipment maintenance and repair costs. In order to meet the strict requirements of industrial production for high-precision flow measurement, the development of electromagnetic flow meters with protective structures has become an inevitable trend.

[0003] Electromagnetic flow meters on the market are mainly used in several key areas such as industrial production process control, material metering, energy management, and environmental monitoring. They integrate the functions of measuring and calculating flow rate into the same device. When conductive liquid passes through its measuring tube, the device generates a magnetic field and sends a signal. After collecting these signals, the device first removes interference signals, then calculates the liquid velocity and total flow rate through its internal microprocessor, and finally displays the data on the screen. It can also transmit the data to other devices. Existing devices often only focus on the accuracy of instrument detection, while neglecting the instrument's protective measures. Electromagnetic flow meters lacking protective facilities are easily corroded, which shortens the service life of the device and reduces the measurement accuracy. Improper sealing of the pipeline can also cause the entire device to fail to operate for a long time.

[0004] Traditional electromagnetic flowmeters suffer from insufficient protection, resulting in a high failure rate in complex industrial environments. Each malfunction requires specialized technicians to repair and replace damaged components, consuming significant human and material resources. Electromagnetic flowmeters with protective structures improve protection levels and reliability, reducing the frequency of failures, lowering maintenance costs and downtime. Furthermore, their detachable and easily accessible design makes maintenance more convenient and efficient, further enhancing overall industrial production efficiency. The application of new materials can improve the protection and durability of electromagnetic flowmeters, while advanced signal processing technology and sensor design can enhance their anti-interference capabilities and measurement accuracy. Against this technological backdrop, developing electromagnetic flowmeters with protective structures, integrating new technologies and materials into product design, is a crucial step in promoting the development of the electromagnetic flowmeter industry and meeting market demands. Therefore, this paper proposes an electromagnetic flowmeter with a protective structure to address the aforementioned problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 5An electromagnetic flowmeter with a protective structure includes a protective top cover 1, primarily used to protect the internal core components from external environmental damage, such as preventing rainwater, dust, and foreign objects from entering the equipment and avoiding damage from external interference factors. A detachable nut 18 is threaded to the bottom of the protective top cover 1, mainly serving to connect and fix the protective top cover 1 to a fixed beam 2, enabling a detachable connection between the two. This provides great convenience for operators while ensuring the connection's firmness and stability. The fixed beam 2, threaded to the bottom of the detachable nut 18, is a crucial supporting component of the entire protective structure, playing a vital role in ensuring the overall protection... To ensure the stability of the protective structure, a protective cover 3 is slidably connected inside the fixed beam 2. This cover is the main part of the electromagnetic flowmeter's protective structure, providing comprehensive protection for key components such as the internal electromagnetic induction pipe 5 and transmission port 15. It also provides electromagnetic shielding to a certain extent. Two transmission ports 15 are fixedly connected to the left side of the protective cover 3 for connecting external signal transmission cables or pipes, enabling data transmission or media flow between the electromagnetic flowmeter and external equipment. The flow data measured by the electromagnetic flowmeter can be accurately transmitted to external equipment such as display instruments and control systems. A hinge 21 is fixedly connected to the outside of the protective cover 3, a key component connecting the protective cover 3 and the inspection door 4. The access door 4 can rotate relative to the protective cover 3, enabling it to open and close. The access door is fixedly connected to the right side of the hinge, providing an openable passage for the internal components of the electromagnetic flowmeter, facilitating routine inspection, maintenance, calibration, and troubleshooting by operators. The protective cover 3 is rotatably connected to the side of the access door 4 closest to it. A latch 22 is fixedly connected to the outside of the access door 4, tightly connecting it to the protective cover 3 to ensure the sealing and robustness of the protective structure.

Used in conjunction with the latch 22, the access door 4 can be opened and closed. The door 4 is connected and fixed to the protective cover 3. The locking bracket 20 is movably connected to the side of the buckle 22. The bottom of the protective cover 3 is fixedly connected to the electromagnetic induction pipe 5, which is the core measuring component of the electromagnetic flowmeter. It is used to measure the flow rate of conductive liquid to calculate the flow rate of the liquid and provide a basis for subsequent data processing and display. Two fixing gaskets 12 are fixedly connected in the middle of the electromagnetic induction pipe 5. They are mainly used to enhance the connection stability and sealing between the nut 13 and the electromagnetic induction pipe 5. The two fixing gaskets 12 are threaded with the nut 13. The main function is to tightly connect the fixing gaskets 12 and the electromagnetic induction pipe 5 together to ensure the accuracy and stability of the electromagnetic flowmeter measurement.

[0034] Reference Figures 2 to 5The top of the electromagnetic induction pipe 5 is fixedly connected to the core converter 14, which directly affects the accuracy, stability, and compatibility of the flow meter's measurement data and output signal. It is the core hub connecting the flow detection and the external control system. Two signal transmission tubes 17 are fixedly connected to the left side of the core converter 14. Their main function is to provide a transmission channel for the signal processed by the core converter 14, ensuring that the signal can be transmitted stably and accurately to the display instrument.

The flow detection display 23 is fixedly connected inside the display cover 16. It is a component that can display the flow data measured by the electromagnetic flow meter in real time, allowing operators to easily understand the flow status of the fluid in the pipe. The bottom of the electromagnetic induction pipe 5 is fixedly connected to the pipe reinforcement layer 6, which mainly enhances the structural strength and rigidity of the electromagnetic induction pipe 5, improving the pipe's pressure resistance and deformation resistance. The middle of the pipe reinforcement layer 6 is fixedly connected to a transition layer. Pipe 9 serves as a transition and connection, allowing for adjustments to pipe diameter, shape, or connection method. A fluid channel 10 is fixedly connected internally to the transition pipe 9. A well-designed fluid channel 10 ensures uniform and stable fluid flow within the pipe, enabling the electromagnetic induction pipe 5 to accurately detect fluid flow information. Sealing flanges 7 are fixedly connected to both sides of the fluid channel 10, connecting the electromagnetic induction pipe 5, the transition pipe 9, and other pipes or equipment. This connection ensures a tight seal at the joint, making the connection more robust. A socket joint 11 is fixedly connected internally to the sealing flange 7, allowing the pipe to be inserted into the joint. Combined with the sealing structure, this achieves a sealed connection. A gasket 8 is fixedly connected to the outer side of the sealing flange 7, filling any small gaps between the flanges to prevent fluid leakage and improve the reliability and service life of the flange connection. Mounting holes are also fixedly connected to the outer side of the sealing flange 7, primarily used to fix the sealing flange 7 to pipe supports, equipment foundations, or other installation structures, enabling the installation and positioning of the electromagnetic flowmeter.

[0035] Working principle: The protective top cover 1 and protective cover 3 provide all-round protection for the internal core converter 14 and flow detection display 23. In addition, the detachable nut 18 and fixing beam 2 on the top facilitate maintenance work by maintenance personnel.
