Description

Technical Field

[0001] The present disclosure relates to a real-time material level measuring instrument and a measuring method for a silo of a polypropylene device. Background Art

[0002] In the process of polypropylene powder storage, accurate material level measurement is crucial for production continuity and safe operation of equipment. Currently, commonly used material level measurement technologies include weight level meter, guided wave radar level meter and nuclear radiation level meter, but there are still many problems when applied in the special environment of polypropylene silo.

[0003] First, the weight level meter uses an electric mechanical plumb bob for measurement, which is relatively simple to install and is not affected by the properties of solids. However, in actual use, the weight level meter often faces problems such as cracking of the flange connection surface, seal failure, steel belt breakage, motor and gear mechanism failure, etc. In addition, its non-continuous measurement method leads to untimely data updates, which affects the accuracy of production statistics and brings great challenges and costs to equipment maintenance.

[0004] Secondly, although the guided wave radar level meter has high accuracy, it needs to install a waveguide inside the silo, which is expensive and difficult to maintain. When the material flow impacts the waveguide, the waveguide is easily damaged, and it is very difficult to repair or replace, making the overall equipment cost more expensive.

[0005] Furthermore, nuclear radiation level meters use radiation detection technology and have the advantage of non-contact measurement, but their installation costs are high and there are major safety risks, especially in chemical parks, where radiation detection operations can easily interfere with the measurement accuracy of the equipment.

[0006] In the high temperature and suspended dusty environment of polypropylene silos, the existing measurement methods have many limitations. The internal temperature of the silo is high, and the operating temperature can reach 88°C, which makes some mechanical and electronic equipment susceptible to heat damage or performance degradation. At the same time, polypropylene powder is suspended in the silo, forming a large amount of dust. These dusts will not only adhere to the key parts of the measuring equipment, such as the radar transceiver, affecting the measurement accuracy, but also aggravate the wear of the equipment and shorten the service life. In addition, the floating and aggregation of dust particles are also easy to interfere with signal transmission. For example, the signals of guided wave radar level meters and nuclear radiation level meters may be scattered or absorbed by dust, resulting in inaccurate or failed measurements. In addition, the dielectric constant of polypropylene powder is usually between 2.1-2.4, indicating that its response to electric fields is weak. This means that in the application of electromagnetic wave technology, polypropylene powder has poor reflection of electromagnetic waves, which further increases the difficulty of measurement. The low reflection intensity of the signal may make the echo signal weak, affecting the accurate identification of the material level by the equipment.

[0007] In summary, high temperature and dusty environments pose significant challenges to the stability, accuracy and durability of level measurement equipment. Summary of the invention

[0008] The purpose of the present invention is to provide a real-time material level measuring instrument for a polypropylene device silo which can adapt to high temperature and dusty environments and has high precision and durability.

[0009] Another object of the present invention is to provide a method for using a real-time material level measuring instrument for a polypropylene device silo that is adaptable to high temperature and dusty environments and has high accuracy and durability.

[0010] To achieve the above objectives, the present invention is implemented through the following technical solutions: a real-time material level measuring instrument for a polypropylene device silo, comprising a measuring instrument body, a connector, a transceiver and an instrument measurement display housing, wherein the measuring instrument body is externally connected to the upper part of the silo through the connector, the transceiver is installed at the lower end of the measuring instrument body, the transceiver is connected to the transmitter in the measuring instrument body, and is used to send and receive material reflection signals in the silo, the instrument measurement display housing is coated on the outside of the measuring instrument body, and the instrument measurement display housing is connected to the measuring instrument body, and is used to display the material level data in the silo in real time, and provide operators with the setting and regulation of material level measurement parameters.

[0011] The real-time material level measuring instrument for the polypropylene device silo can adapt to high temperature and dusty environments, has high precision and durability, and solves the limitations of traditional material level measuring equipment under special working conditions of polypropylene silos. Its core structure includes the measuring instrument body, connector, transceiver and instrument measurement display housing. The measuring instrument body is installed on the upper part of the silo through the connector. This external installation design effectively avoids the direct exposure of the measuring instrument body to the high temperature environment inside the silo, thereby reducing the risk of equipment failure and performance degradation caused by high temperature. The transceiver is installed at the lower end of the measuring instrument body. The transmitter inside the measuring instrument body transmits and receives the material reflection signal in the silo, and converts it into real-time material level data, which is convenient for operators to monitor and adjust.

[0012] The real-time material level measuring instrument for the silo of the polypropylene unit adopts a "downward-looking" measurement system based on the principle of frequency modulated continuous wave (FMCW). The transceiver transmits electromagnetic waves with continuously changing frequencies, which can penetrate the dust inside the silo and reach the surface of the material. The reflected echo is then received by the transceiver. This design enables the instrument to maintain good signal strength in a dusty environment, ensuring the stability and accuracy of the measurement. At the same time, FMCW technology has strong anti-interference ability, which can effectively reduce the impact of dust on signal transmission.

[0013] Furthermore, a transceiver angle adjustment device is provided on the upper side section of the transceiver, and the transceiver angle adjustment device is threadedly connected to the transceiver and can adjust the transmission angle of the transceiver to optimize the signal reception effect.

[0014] The transceiver angle adjustment device is located on the upper side of the transceiver and is connected to the transceiver through threads. It can flexibly adjust the transmission angle of the transceiver according to different working conditions. In this way, the transceiver can better adapt to the material distribution inside the silo, optimize the signal reception effect, and improve the measurement accuracy and stability.

[0015] Furthermore, a purge interface is provided on the side of the measuring instrument body, and the purge interface is connected to the bottom of the connector and is used to purge the surface of the transceiver to prevent material adhesion or dust accumulation from affecting the measurement accuracy.

[0016] The design of the purge interface effectively solves the problem of dust and material adhesion. The purge interface is set on the side of the measuring instrument body and is connected to the bottom of the connector. When the instrument is running, the surface of the transceiver can be purged through the interface to prevent material or dust from accumulating on the transceiver, avoiding measurement errors or instrument damage caused by this, further extending the service life of the instrument and ensuring long-term efficient operation. Through these improvements, the real-time material level measuring instrument for the polypropylene device silo can maintain high measurement accuracy in high temperature and dusty environments, and improve the durability and maintainability of the instrument, making it more suitable for use in polypropylene silos.

[0017] Furthermore, the connector is a standard flange or a UNI flange.

[0018] Furthermore, the transceiver uses a horn antenna or a water drop antenna.

[0019] Furthermore, the transceiver angle adjustment device makes the maximum deviation angle of the axis of the transceiver in all directions be 15°, and selectively adjusts the emission angle of the measurement signal according to the stacking angle of the solid bulk material in the silo, optimizes the signal reception and measurement accuracy, and ensures that the device can measure the real-time level of the material in the silo more accurately and stably.

[0020] In a silo, the stacking angle of bulk solids may affect the true reflected signal of the material level. If the transmitting angle of the transceiver cannot adapt to different stacking angles, it may cause signal reflection distortion or the appearance of a measurement blind spot. The transceiver angle adjustment device allows the transceiver to adjust the transmitting angle within a maximum range of 15°, so that the instrument can flexibly respond to these changes, thereby optimizing the signal reception effect and ensuring that the instrument can maintain high-precision real-time material level measurement under different working conditions. This design improves the stability and measurement accuracy of the instrument, making it more suitable for complex and changing industrial environments.

[0021] Furthermore, the real-time material level measuring instrument for the polypropylene device silo also includes a data acquisition unit, which is connected to the measuring instrument body. The data acquisition unit has a signal processing function and is used to receive real-time material level data from the measuring instrument body and centrally store and preliminarily process the data.

[0022] The data acquisition unit is used to receive, process and store real-time material level data from the measuring instrument. First, the data acquisition unit can receive the material level signal from the measuring instrument in real time and convert it into readable material level information for the operator to view. Secondly, the data acquisition unit has preliminary data processing functions, such as denoising and filtering, which can eliminate interference in the signal and ensure the accuracy of the data. In addition, it can also centrally store the collected material level data, which is convenient for subsequent data analysis and historical record query, and helps operators better monitor and manage material changes in the silo.

[0023] Furthermore, the real-time material level measuring instrument for the polypropylene device silo also includes a central control unit, which is connected to the data acquisition unit. The central control unit further processes the material level data transmitted by the data acquisition unit and can send an alarm signal according to a preset material level threshold to remind the operator to adjust the material delivery or discharge to ensure the material level safety during the production process.

[0024] After receiving the material level data transmitted by the data acquisition unit, the central control unit further processes and analyzes the data in depth. It ensures the accuracy and reliability of the measured data through advanced algorithms or logical operations, and responds accordingly according to the preset material level threshold. When the material level reaches or exceeds the set safety range, the central control unit will automatically send out an alarm signal to remind the operator to take timely measures to adjust the material delivery or discharge, thereby avoiding the risk of overfilling the silo or too low material level during the production process. Through such functional design, the central control unit plays a core control role in the instrument, which not only ensures the accuracy of material level measurement, but also improves the safety and stability of the entire production process. This enables operators to manage the flow of materials in the silo more efficiently, avoid shutdowns, equipment failures or safety hazards caused by abnormal material levels, and ensure smooth production processes.

[0025] Furthermore, the central control unit is connected to the instrument measurement display housing, which can display the material level data from the measuring instrument body in real time, and can synchronously display the alarm information and overall status processed by the central control unit, so as to facilitate on-site management and operation by operators.

[0026] The connection between the central control unit and the instrument measurement display housing enables the operator to view the material level data in the silo in real time through the instrument measurement display housing, as well as the alarm information processed by the central control unit and the overall operating status of the equipment. The instrument measurement display housing not only displays the material level data from the measuring instrument body in real time, but also synchronously updates the processing results of the central control unit, including alarm signals and various states of the instrument. The convenience of on-site management is greatly improved. Operators can intuitively monitor the status of the silo, timely understand whether the material level has reached the preset threshold, and quickly make corresponding adjustments based on the alarm information, thereby avoiding potential risks in production. Through integration, on-site management and operation become more efficient and safe, ensuring the normal operation of work and precise control of material levels.

[0027] Furthermore, the real-time material level measuring instrument for the polypropylene device silo also includes a remote monitoring unit, which is connected to the central control unit. The operator can access the central control unit in real time through the remote monitoring unit to view the real-time material level data and historical data trends in the silo, and can remotely adjust the parameters of the equipment to achieve remote management of the silo.

[0028] The function of the remote monitoring unit is to remotely manage and monitor the real-time material level measuring instrument of the silo of the polypropylene unit. It is connected to the central control unit, allowing operators to view the material level data in the silo and its historical data trend in real time by remotely accessing the central control unit. In this way, the operator can understand the operating status of the silo at any time, monitor the changes of materials, and ensure the smooth progress of the production process when away from the site.

[0029] In addition, the remote monitoring unit also has a remote adjustment function. The operator can modify the instrument's working parameters, such as the alarm threshold of the material level, the measurement cycle, etc., through the remote monitoring unit according to actual needs. In this way, the operator can flexibly respond to changes in the production process and make adjustments in time without having to go to the site for operation. This function not only improves the convenience of management, but also reduces the frequency of on-site operations, reduces the need for manual intervention, improves work efficiency, and ensures the intelligence, automation and safety of silo management.

[0030] Furthermore, the instrument measurement display housing has a user-friendly interface and operating experience, supports multi-language display and customized parameter settings, and adapts to different production environments and operating requirements.

[0031] The user-friendly interface and operating experience of the instrument measurement display housing greatly improve the work efficiency and convenience of operators. The multi-language display function enables it to adapt to the needs of operators from different regions and language backgrounds, ensuring that all types of personnel can easily understand and use the instrument and avoid operating errors caused by language barriers. At the same time, the customized parameter setting function allows operators to adjust the working parameters of the instrument, such as material level display format, alarm threshold, measurement frequency, etc., according to specific production environments and needs. This flexibility ensures that the instrument can adapt to different industrial application scenarios and provide highly personalized solutions. Through such a design, the instrument measurement display housing not only improves the ease of use of the instrument, but also enhances the accuracy and efficiency of operation, which helps to better realize the precise monitoring and management of silos.

[0032] The present disclosure provides a measurement method, comprising the following steps:

[0033] S1. Adjust the transceiver angle adjustment device according to the stacking angle of the solid bulk material in the silo to ensure that the transmitting signal of the transceiver can best cover the material surface and maximize the reception effect and measurement accuracy of the reflected signal;

[0034] S2, transmit the signal to the inside of the silo through the transceiver connected to the measuring instrument body, and the signal is reflected by the surface of the material and then returns to the transceiver;

[0035] S3, the transceiver receives the reflected signal and transmits the signal to the data acquisition unit;

[0036] S4, the data acquisition unit performs preliminary processing on the received signal and sends the data to the central control unit;

[0037] S5. The central control unit further analyzes the data and calculates the material level in the silo in real time;

[0038] S6. The real-time material level information is displayed on the display shell through the instrument measurement;

[0039] S7. Purge interface: Purge the surface of the transceiver regularly to prevent material adhesion or dust accumulation from affecting signal reception and measurement accuracy.

[0040] The real-time material level measuring instrument and measuring method of the polypropylene device silo provided by the present invention adopts an external connection design of the connector, so that the measuring instrument body is not directly exposed to the high temperature environment, reducing the influence of high temperature on the instrument, and effectively reducing the failure and performance degradation caused by high temperature. Secondly, the real-time material level measuring instrument of the polypropylene device silo adopts frequency modulation continuous wave (FMCW) technology, which can penetrate the dust in the silo, ensure signal strength and measurement stability, and solve the problems of signal attenuation and inaccurate measurement of traditional equipment in dusty environments. At the same time, the setting of the transceiver angle adjustment device flexibly adjusts the transmission angle of the transceiver and optimizes the signal reception effect, so as to adapt to the needs of different working conditions. In addition, the addition of a purge interface to the measuring instrument body can regularly clean the surface of the transceiver, prevent the adhesion of dust and materials, avoid measurement errors, further improve the accuracy of the measurement and extend the service life of the instrument. The measuring method of the present invention ensures the high accuracy and stability of the material level measurement through precise parameter settings and real-time data feedback mechanism, and can effectively realize automation and efficient material level monitoring even in complex working environments.

[0054] The setting of the horn antenna 301 enhances the emission and reception capabilities of electromagnetic waves, ensuring stable signal transmission in dusty silo environments. This design greatly reduces signal attenuation caused by dust interference and ensures measurement stability and accuracy. By using the external standard flange 201, the measuring instrument body can be easily installed outside the silo without direct contact with high-temperature materials, which not only extends the service life of the instrument, but also reduces the risk of failure due to high-temperature environments.

[0060] The water drop-shaped antenna 302 can better adapt to the complex environment in the silo, especially when the material has strong adhesion or there is a lot of dust. The smooth surface of the water drop-shaped antenna 302 helps to reduce dust accumulation and material adhesion, thereby improving the stability of signal reception and the accuracy of measurement. In order to further prevent the accumulation of materials or dust from affecting the measurement accuracy, a purge interface 5 is designed on the side of the measuring instrument body. The purge interface 5 is connected to the bottom of the standard flange 201, and the operator can introduce gas (such as compressed air) through the interface to regularly purge the surface of the water drop-shaped antenna 302. Through the purge operation, the material or dust that may be attached to the surface of the water drop-shaped antenna 302 is effectively cleaned, the cleanliness of the water drop-shaped antenna 302 is maintained, and the smooth transmission of the material level signal is ensured. The purge design greatly reduces the frequency and difficulty of manual maintenance, reduces the measurement error caused by dust accumulation or material adhesion, and improves the operating stability of the device. The use of the standard flange 201 connection method makes the instrument easy to install and maintain. Through these designs, the efficiency of material management in the silo is effectively improved, while the workload of manual cleaning and maintenance is reduced, and the durability of the equipment and its ability to operate stably for a long time are enhanced.
