Description

Technical Field

[0001] This utility model relates to the field of material level monitoring technology, specifically a full-load measurement device for raw material silos in glass factories. Background Technology

[0002] A raw material warehouse is a warehouse for storing raw materials used in production, and these warehouses are generally large in scale. In the glass production process, glass factories usually have large raw material warehouses. Raw materials are injected into the warehouse from the outside, and when it is necessary to discharge them, they are discharged from the bottom, completing the glass raw material conveying and batching operation. When external vehicles and other equipment fill the warehouse, the full status monitoring of the raw material warehouse directly affects the continuity and safety of production. Therefore, it is necessary to measure the fullness of the warehouse.

[0003] Traditional measuring devices often employ single technologies, such as level gauges or touch switches. While these technologies are low-cost, their measurement accuracy is easily affected by high temperatures, dust, and changes in the angle of repose of the material within the silo. They cannot provide real-time feedback on material level, and their ability to measure full material levels inside the silo is relatively poor. Furthermore, their ability to indicate full material levels is relatively inadequate, and their installation within the silo is not convenient enough. Insufficient installation levelness affects measurement accuracy, and the installation and operation of the device are not very convenient. Therefore, we propose a full-silo measuring device for raw material silos in glass factories to solve the above problems. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a full-load measurement device for raw material silos in glass factories.

[0005] The glass factory raw material warehouse full-fill measurement device proposed in this utility model includes a mounting base installed on the top wall of the inner cavity of the raw material warehouse. A movable seat is hinged to the bottom of the mounting base, and the installation level of the movable seat is maintained by a driving component. An imaging rangefinder and an infrared rangefinder are installed at the bottom of the movable seat, and both the imaging rangefinder and the infrared rangefinder are controlled by a PLC control cabinet outside the raw material warehouse.

[0006] Traditional measuring devices suffer from numerous problems when measuring full loads in glass factory raw material silos, such as significant interference from the silo environment and low measurement accuracy. This device addresses these issues by installing a mounting base on the top wall of the raw material silo with a hinged movable base at the bottom, and using a drive mechanism to maintain its horizontal position. This ensures that the imaging rangefinder and infrared rangefinder can stably and accurately acquire material level information. The imaging rangefinder and infrared rangefinder measure using different principles: the imaging rangefinder obtains visual information about the material level through image analysis, while the infrared rangefinder measures distance using infrared light. The two work together to reduce errors from individual technologies and improve measurement accuracy. Furthermore, controlled by a PLC control cabinet, the device can monitor the material level in real time and provide timely feedback on the full load status, allowing staff to monitor the silo situation, prevent overflow, and ensure production continuity and safety.

[0007] As a further optimized solution of this utility model, the driving component is a telescopic rod, and the two ends of the telescopic rod are respectively hinged to the mounting base and the movable base. The telescopic rod is preferably an electric push rod.

[0008] The telescopic rod is selected as the driving component, which is simple in structure and easy to operate. The two ends of the telescopic rod are hinged to the mounting base and the movable base respectively, which allows for flexible adjustment of the angle and position of the movable base. If the movable base tilts during installation, it can be restored to horizontal by adjusting the length of the telescopic rod, ensuring the measurement accuracy of the imaging rangefinder and infrared rangefinder. When the raw material silo undergoes slight deformation due to vibration or other factors, the telescopic rod can also be adjusted in time to maintain the horizontality of the movable base and ensure the stable operation of the measuring device.

[0009] As a further optimization of this utility model, a level is installed on the side of the movable seat;

[0010] The spirit level provides installers with an intuitive basis for judging the levelness. When installing the movable seat, workers can quickly determine whether the movable seat is level by observing the position of the bubble on the spirit level. If the bubble deviates from the center position, it means that the movable seat is tilted. At this time, the levelness of the movable seat can be adjusted by adjusting the length of the telescopic rod. This design is simple and effective, which can help workers install accurately and avoid increased measurement errors of the imaging rangefinder and infrared rangefinder due to non-level installation, thereby improving the installation accuracy and measurement accuracy of the measuring device.

[0011] As a further optimization of this utility model, an adhesive plate is installed on the upper end face of the mounting base, and the mounting base is bonded to the inner cavity top wall of the raw material silo through the adhesive plate to complete the pre-installation.

[0012] The adhesive plate is used for the pre-installation of the mounting base. This method makes the installation process more convenient. In the early stage of installation, the adhesive plate is used to initially fix the mounting base to the top wall of the inner cavity of the raw material silo. This can prevent the mounting base from moving at will during further installation and facilitates precise adjustment of its position later. Compared with the direct use of screws and other fixing methods, pre-installation can improve installation efficiency, reduce installation time, and also provide convenient conditions for subsequent precise installation.

[0013] Furthermore, the adhesive plate has a rectangular frame structure, and a magnetic suction plate located at the center of the inner frame of the adhesive plate is installed on the upper end face of the mounting base, and the magnetic suction plate is magnetically connected to the top wall of the inner cavity of the raw material hopper.

[0014] The adhesive plate adopts a rectangular frame structure, which can ensure a certain bonding area without obstructing the magnetic connection between the magnetic plate and the top wall of the raw material hopper cavity. The magnetic connection between the magnetic plate and the top wall of the raw material hopper cavity further enhances the stability of the pre-installation. During the pre-installation of the mounting base, the magnetic attraction between the magnetic plate and the top wall of the raw material hopper cavity cavity can quickly locate the center position of the mounting base, and at the same time, it can assist in fixing the mounting base to a certain extent, making the installation process more convenient and faster, and improving installation efficiency and accuracy.

[0015] As a further optimization of this utility model, a plurality of screws are installed at the edge of the mounting base and evenly distributed along its circumference, and screw holes corresponding to and adapted to the screws are opened on the top wall of the inner cavity of the raw material silo.

[0016] The multiple screws at the edge of the mounting base engage with the screw holes on the top wall of the raw material silo's inner cavity, which is an important way to finally fix the mounting base. The screws, which are evenly distributed around the circumference, make the connection between the mounting base and the top wall of the raw material silo's inner cavity more secure, preventing the mounting base from loosening due to vibration, material impact, or other factors during long-term use. This fixing method not only ensures the stability of the measuring device, but also facilitates disassembly and reinstallation when maintenance or replacement of parts is required, thus improving the maintainability of the equipment.

[0017] As a further optimization of this utility model, a data connection terminal is installed at the bottom of the movable base. The input terminal of the data connection terminal is electrically connected to the imaging rangefinder and the infrared rangefinder, respectively, and the output terminal of the data connection terminal is wirelessly connected to the input terminal of the PLC control cabinet.

[0018] The data connection terminal enables data transmission between the measuring equipment and the PLC control cabinet. Its input terminal is electrically connected to the imaging rangefinder and infrared rangefinder to collect measurement data, and its output terminal is wirelessly connected to the PLC control cabinet to transmit data to the PLC control cabinet. The wireless connection method reduces the complexity of wiring and avoids problems such as line damage and signal interference caused by wiring, thereby improving the stability and reliability of data transmission. At the same time, it allows staff to remotely receive and process measurement data outside the raw material warehouse, promptly monitor the warehouse's full status, and improve work efficiency.

[0019] As a further optimization of this utility model, an auxiliary lighting lamp and a storage battery are installed at the bottom of the movable seat, and the output terminal of the storage battery is electrically connected to the driving component, the imaging rangefinder camera, and the infrared rangefinder respectively.

[0020] Auxiliary lighting plays an important role in the dimly lit environment of raw material warehouses. There may be insufficient light in the raw material warehouses of glass factories, which will affect the normal operation of imaging rangefinders. Auxiliary lighting can provide sufficient illumination to ensure that the imaging rangefinders can clearly obtain material level image information and ensure the accuracy of measurement.

[0021] The battery powers the drive components, imaging rangefinder, and infrared rangefinder. In the event of a sudden power outage, it can maintain the device's normal operation for a period of time, preventing measurement interruptions due to power failure, ensuring the continuity and integrity of data, and improving the device's reliability and stability.

[0022] As a further optimization of this utility model, an audible and visual alarm is installed at the bottom of the movable seat, and the input end of the audible and visual alarm is electrically connected to the output end of the imaging rangefinder camera and the infrared rangefinder, respectively.

[0023] The audible and visual alarm is connected to the imaging rangefinder and infrared rangefinder to provide timely reminders. When the imaging rangefinder or infrared rangefinder detects that the raw material silo is close to full, it will transmit a signal to the audible and visual alarm, which will then sound an alarm to attract the attention of the staff. This design allows the staff to take timely measures, such as stopping the feeding, to avoid raw material spillage, waste, and safety accidents. It also enhances the measurement and alerting capabilities of the device and improves the safety and user experience of the equipment.

[0024] The glass factory raw material silo full-load measurement device proposed in this utility model has the following beneficial effects:

[0025] (I) The device has a movable seat hinged to the bottom of the mounting base on the top wall of the raw material silo, and the installation level is maintained by the drive component. An imaging rangefinder and an infrared rangefinder are installed at the bottom of the movable seat, and both are controlled by the PLC control cabinet outside the raw material silo. By working together, the imaging rangefinder and the infrared rangefinder can obtain material level information from different angles, reduce the error caused by a single technology, and improve the measurement accuracy. At the same time, they can monitor the material level height in real time and transmit the data to the PLC control cabinet to realize real-time feedback on the full status of the raw material silo. This allows the staff to keep abreast of the silo situation and avoid problems such as overflow caused by full silo, thus ensuring the continuity and safety of production.

[0026] (II) The mounting base of this device can be bonded to the top wall of the inner cavity of the raw material silo by multiple adhesive plates, and the magnetic plate can be magnetically connected to the top wall of the inner cavity of the raw material silo to complete the pre-installation. Then, the mounting base is installed by multiple screws on the edge of the mounting base and the screw holes on the top wall of the inner cavity of the raw material silo. This ensures the firmness of the installation and facilitates the adjustment of the installation position. In addition, the level ruler installed on the side of the movable base allows the staff to observe the levelness during the installation process, ensuring that the movable base is installed horizontally, thereby ensuring the measurement accuracy of the imaging rangefinder and infrared rangefinder.

[0027] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0034] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0035] In the glass factory production process, accurate measurement of the full state of the raw material warehouse is crucial for the continuity and safety of production. However, traditional measuring devices have many drawbacks. The measuring device of this utility model aims to solve these problems, and its specific implementation is as follows:

[0036] like Figure 1 and Figure 2 As shown, when installing the measuring device, the connection between the mounting base 2 and the raw material bin 1 is first addressed. A rectangular frame adhesive plate 4 is installed on the upper surface of the mounting base 2. The mounting base 2 is initially fixed by bonding the adhesive plate 4 to the inner cavity top wall of the raw material bin 1.

[0037] like Figure 3 As shown, while the mounting base 2 is initially fixed, a magnetic suction plate 3 is also installed on the upper end face of the mounting base 2 at the center of the inner frame of the adhesive plate 4. The magnetic suction plate 3 is magnetically connected to the top wall of the inner cavity of the raw material bin 1. This not only helps to fix the mounting base 2, but also quickly locates its center position, which is convenient for subsequent precise adjustment.

[0038] Next, using the multiple screws 11 evenly distributed circumferentially along the edge of the mounting base 2, tighten them to the corresponding screw holes on the top wall of the inner cavity of the raw material bin 1 to complete the final fixing of the mounting base 2;

[0039] This method of pre-installing and then precisely fixing ensures both ease of installation and robustness, facilitating subsequent maintenance or component replacement.

[0040] like Figure 1 As shown, the bottom of the mounting base 2 is hinged to the movable base 5, and the two ends of the drive telescopic rod 6 are respectively hinged to the mounting base 2 and the movable base 5. When installing the movable base 5, the operator can adjust its levelness by observing the level ruler 12 installed on the side of the movable base 5. If the level ruler 12 shows that the movable base 5 is not level, it can be adjusted by adjusting the length of the telescopic rod 6 to ensure that the movable base 5 is in a level state, providing a stable foundation for the accurate measurement of the imaging rangefinder camera 7 and the infrared rangefinder 8.

[0041] like Figures 1-4 As shown, the bottom of the movable base 5 is equipped with an imaging rangefinder camera 7, an infrared rangefinder 8, a data connection terminal 9, an auxiliary lighting lamp 13, a storage battery 14, and an audible and visual alarm 15. The imaging rangefinder camera 7 and the infrared rangefinder 8 measure the material level in the raw material silo from different principles. The imaging rangefinder camera 7 obtains visual information about the material level through image analysis, while the infrared rangefinder 8 uses infrared light to measure the distance. The two work together to reduce the error caused by a single technology and improve the measurement accuracy.

[0042] Measurement data is transmitted from the imaging rangefinder camera 7 and the infrared rangefinder 8 to the data connection terminal 9. The output of the data connection terminal 9 is wirelessly connected to the PLC control cabinet 10 outside the raw material silo 1, transmitting the measurement data to the PLC control cabinet 10 in real time. In the dimly lit environment of the raw material silo, the auxiliary lighting 13 provides sufficient illumination for the imaging rangefinder camera 7 to ensure that it can clearly obtain material level image information. The battery 14 supplies power to the drive telescopic rod 6, the imaging rangefinder camera 7, and the infrared rangefinder 8. In the event of a sudden power outage, the device can maintain normal operation for a period of time to ensure the continuity and integrity of the data.

[0043] When the imaging rangefinder 7 or the infrared rangefinder 8 detects that the raw material silo is close to full, it will transmit a signal to the audible and visual alarm 15. After receiving the signal, the audible and visual alarm 15 will issue an audible and visual alarm to promptly remind the staff to take appropriate measures, such as stopping the feeding, to avoid raw material overflow causing waste and safety accidents. In this way, the device realizes real-time monitoring and timely reminder of the full state of the raw material silo, ensuring the continuity and safety of production.

[0044] It should be noted that all the devices in this application are common devices on the market, and can be selected according to the needs of specific use. The circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection. Those skilled in the art can easily implement it. It belongs to the prior art and will not be described in detail.

[0045] 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.
