Description

Technical Field

[0001] This utility model relates to the field of temperature measuring device technology, specifically to an online temperature measuring device for finished product silos. Background Technology

[0002] In fields such as feed production, temperature monitoring of finished product silos is crucial, as abnormal material temperatures can lead to material deterioration and affect product quality. Traditional methods for monitoring finished product temperature mostly involve manual measurement using temperature guns at regular intervals. This method has significant drawbacks: firstly, the temperature data is not real-time, making it impossible to detect abnormal temperatures promptly; secondly, temperature measurement requires temporary shutdowns, impacting packaging efficiency.

[0003] With technological advancements, some online temperature monitoring devices have emerged. However, existing devices generally suffer from the following problems: fixed measurement points, limiting their ability to measure ambient temperature at a single location, and an inability to comprehensively acquire ambient temperature data from different locations, such as those near and far from the machine. This results in inaccurate and incomplete data when comparing finished product temperatures with ambient temperatures, affecting the reliability of alarm mechanisms. Therefore, there is an urgent need for an online temperature monitoring device for finished product silos that can monitor temperature in real-time and comprehensively, and possess automated intelligent alarm functions. Utility Model Content

[0004] The purpose of this invention is to provide an online temperature measurement device for finished product silos. Through a microcontroller and a preset program, it can automatically collect temperature data inside the finished product silo and ambient temperature data at different locations, performing real-time comparison and calculation. When the ambient temperature is above 15℃, an audible and visual alarm is triggered when the finished product temperature exceeds the ambient temperature by 5℃; when the ambient temperature is below 15℃, an alarm is triggered when the finished product temperature exceeds 20℃. No manual intervention is required, solving the problems of inefficiency and lack of real-time monitoring associated with traditional manual temperature measurement. This improves the timeliness and accuracy of temperature monitoring and addresses the issue of fixed measurement points that can only measure the ambient temperature at a single location, failing to comprehensively acquire ambient temperature data from different locations such as near and far from the machine. This results in inaccurate and incomplete data when comparing the finished product temperature with the ambient temperature, affecting the reliability of the alarm mechanism.

[0005] To achieve the above objectives, an online temperature measurement device for finished product silos is provided, comprising a control box, a thermometer, and a drive mechanism. The drive mechanism includes a mounting plate, a motor, a threaded rod, and an auxiliary rod. The mounting plate is fixedly installed on the outside of the finished product silo, the motor is fixedly installed on one end of the mounting plate, the threaded rod is coaxially connected to the output shaft of the motor, and the auxiliary rod is parallel to one side of the threaded rod and fixedly connected to the mounting plate. The thermometer is connected to the threaded rod and the auxiliary rod via a connecting block. The connecting block has a threaded hole that mates with the threaded rod and a sliding hole that mates with the auxiliary rod. The motor drives the threaded rod to rotate, thereby causing the connecting block to reciprocate along the threaded rod and the auxiliary rod, enabling the thermometer to move to different positions near and away from the machine to measure the ambient temperature. A data display screen and an audible and visual alarm are provided on the outside of the control box, and the thermometer, data display screen, and audible and visual alarm are all electrically connected to the control module inside the control box.

[0006] As a further improvement to this technical solution, the control box is equipped with a microcontroller, a 24V power supply box, a 5V power supply box, a conversion module, and an output module. The 24V power supply box is connected to the 5V power supply box via wires. The conversion module is electrically connected to the 24V power supply box, the 5V power supply box, and the microcontroller, respectively, for converting 24V power to 5V power and supplying it to the microcontroller. The output module is electrically connected to the microcontroller and is used to output control signals to the drive mechanism and the audible and visual alarm.

[0007] As a further improvement to this technical solution, a relay control board is also provided inside the control box. The relay control board is electrically connected to the microcontroller and is used to receive control signals from the microcontroller and control the start, stop and direction of the motor.

[0008] As a further improvement to this technical solution, the temperature sensor includes a temperature display screen and a plug. The plug is detachably connected to the wires leading out from the control box. The temperature display screen is located on the outside of the temperature sensor and is electrically connected to the internal temperature sensor. The temperature sensor is electrically connected to the microcontroller inside the control box through the plug and the wires.

[0009] As a further improvement to this technical solution, the auxiliary block is disposed at the other end of the threaded rod and fixedly connected to the mounting plate to support the end of the threaded rod and ensure the stability of the threaded rod when it rotates.

[0010] As a further improvement to this technical solution, the data display screen is used to display the temperature inside the finished product silo and the ambient temperature at different locations collected by the temperature sensor in real time. The audible and visual alarm is used to issue an audible and visual alarm signal when the difference between the finished product temperature calculated by the microcontroller and the ambient temperature exceeds a preset threshold (the difference is >5℃ when the ambient temperature is above 15℃ or the material temperature is >20℃ when the ambient temperature is below 15℃).

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This online temperature monitoring device for finished product silos automatically collects temperature data from inside the silo and ambient temperatures at different locations using a microcontroller and pre-programmed settings, and performs real-time comparison and calculation. When the ambient temperature is above 15℃, an audible and visual alarm is triggered when the finished product temperature exceeds the ambient temperature by 5℃; when the ambient temperature is below 15℃, an alarm is triggered when the finished product temperature exceeds 20℃. No manual intervention is required, solving the problems of unreal-time and inefficient traditional manual temperature monitoring, and improving the timeliness and accuracy of temperature monitoring.

[0012] 2. In this online temperature measurement device for finished product silos, the temperature sensor is driven to reciprocate along the mounting plate by a drive mechanism motor, threaded rod, auxiliary rod, etc., so that the temperature sensor can move to different positions near and far from the machine to measure the ambient temperature, obtain more comprehensive ambient temperature data, avoid the limitations of a single fixed temperature measurement point, make the comparison between the temperature of the finished product and the ambient temperature more scientific and accurate, and improve the reliability of the system.

[0013] 3. In this online temperature measurement device for finished product silos, the temperature sensor is connected to a threaded rod and an auxiliary rod via a connecting block. The design of the threaded hole and sliding hole ensures the stability and flexibility of the temperature sensor during movement. Simultaneously, the auxiliary block's support for the threaded rod further enhances the structural stability of the entire drive mechanism, ensuring long-term reliable operation of the device. The data display screen shows the temperature inside the finished product silo and the ambient temperature in real time, allowing operators to intuitively observe temperature changes. The detachable plug design facilitates the installation and maintenance of the temperature sensor, improving the device's usability.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] This utility model embodiment provides an online temperature measurement device for finished product silos, which includes the following solutions: For details, please refer to Figures 1-4 As shown, the device includes a control box 1, with a data display screen 2 and an audible and visual alarm 3 installed on the outside. The control box 1 integrates a control module, which is electrically connected to the temperature sensor 5 and the drive mechanism motor 10 via wires 4. As the core of the device, it manages data processing, power supply, and alarm output in a unified manner, enabling all components to work together.

[0020] The thermometer 5 is mechanically connected to the threaded rod 11 and auxiliary rod 13 of the drive mechanism via the connecting block 8; it is detachably electrically connected to the wire 4 led out from the control box 1 via the plug 7. The detachable design facilitates installation and maintenance, while the mechanical connection ensures stable temperature acquisition when moving with the drive mechanism.

[0021] Please see Figure 2 As shown, mounting plate 9 is fixed to the outside of the finished product silo and serves as the mounting base for motor 10, threaded rod 11, and auxiliary rod 13. The output shaft of motor 10 is coaxially connected to threaded rod 11 and receives signals from control box 1 through relay control board. Threaded rod 11 engages with threaded hole of connecting block 8. When motor 10 drives it to rotate, it drives connecting block 8 to move linearly. Auxiliary rod 13 is parallel to threaded rod 11 and engages with sliding hole of connecting block 8 to provide guidance and prevent connecting block 8 from rotating. Auxiliary block 12 is fixed to the end of threaded rod 11 to support threaded rod 11 and enhance rotational stability.

[0022] Motor 10 drives threaded rod 11 to rotate, and through threaded transmission and auxiliary rod 13 guidance, makes temperature sensor 5 move back and forth along the outside of the hopper, covering different ambient temperature measuring points near / away from the machine.

[0023] Please see Figure 4 As shown, the 24V power supply box 14 inputs power to the 5V power supply box 17 through the wire 4. The conversion module 16 converts 24V to 5V to power the microcontroller 18. The graded power supply meets the voltage requirements of different components, such as the motor 10 which requires 24V and the microcontroller 18 which requires 5V, ensuring the stable operation of the system. The microcontroller 18 obtains 5V power through the conversion module 16, connects to the relay control board and the audible and visual alarm 3 through the output module 15, and connects to the temperature sensor of the thermometer 5 through the wire 4.

[0024] As the control core, it receives temperature data, processes it, and outputs control signals such as driving motor 10 and triggering alarms.

[0025] The relay control board is electrically connected to the microcontroller 18, and its output port is connected to the motor 10. It amplifies the control signal of the microcontroller 18 and precisely controls the start, stop, and direction of the motor 10 to realize the reciprocating movement of the temperature sensor 5.

[0026] Please see Figure 3 As shown, the temperature display screen 6 is integrated on the outside of the thermometer 5 and is electrically connected to the internal temperature sensor. It displays the current temperature at the measuring point in real time and provides local visualization of temperature data for easy on-site viewing. The plug 7 matches the end plug 7 of the wire 4 led out from the control box 1, enabling the thermometer 5 to be detachably connected to the circuit system. This allows the thermometer 5 to be disassembled and maintained independently without affecting the overall circuit.

[0027] The data display screen 2 is fixed on the outside of the control box 1 and electrically connected to the microcontroller 18. It receives and displays data such as the temperature of the finished product and the ambient temperature, and remotely displays the temperature of multiple measuring points, which is convenient for operators to monitor in real time.

[0028] The audible and visual alarm 3 is electrically connected to the microcontroller 18 and receives alarm signals through the output module 15. When the temperature difference exceeds the preset threshold, such as when the ambient temperature is >15℃ and the material temperature exceeds the ambient temperature by 5℃, or when the ambient temperature is <15℃ and the material temperature exceeds the ambient temperature by 20℃, an audible and visual alarm will be issued simultaneously to improve the efficiency of abnormal response.

[0029] Working principle: The 24V power supply box 14 supplies power to the 5V power supply box 17, motor 10 and other components through the wire 4. The conversion module 16 converts 24V to 5V to power low-voltage components such as the microcontroller 18 and the temperature sensor of the temperature sensor 5. After the microcontroller 18 is initialized, it starts the motor 10 through the relay control board, drives the threaded rod 11 to rotate, and drives the connecting block 8 to move back and forth along the auxiliary rod 13, so that the temperature sensor 5 moves closer to / away from the machine at different positions outside the hopper. The temperature sensor of the temperature measuring device 5 collects the ambient temperature or the temperature inside the finished product silo in real time, and the data is transmitted to the microcontroller 18 through the plug 7 and the wire 4. Temperature display screen 6 synchronously displays the local temperature, while data display screen 2 summarizes and displays data from all measuring points in real time. When the average value of the ambient temperature collected by the temperature sensor 5 at multiple locations is greater than 15℃, if the temperature difference between the finished product and the ambient temperature is greater than 5℃, the audible and visual alarm 3 will be triggered through the output module 15. When the ambient temperature is <15℃, if the finished product temperature is >20℃, an alarm is triggered, which is combined with the threshold logic in the Zhengda document. The relay control board controls the motor 10 to start and stop according to the instructions of the microcontroller 18, ensuring that the thermometer 5 moves cyclically along the preset path, covering the full range of measuring points. The operator monitors the temperature changes in real time through the data display screen 2. In case of abnormality, the audible and visual alarm 3 prompts for quick troubleshooting. When maintenance is required, the plug 7 of the thermometer 5 can be disconnected and disassembled for repair without affecting the operation of other parts of the system.

[0030] 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.
