Description

Technical Field

[0001] This utility model relates to the field of integrated monitoring device technology, specifically to an integrated monitoring device for a high-frequency heating and quality improvement process. Background Technology

[0002] As a typical low-rank coal, lignite has low direct combustion efficiency and large pollutant emissions due to its high moisture content, high volatile matter and low calorific value. In order to improve its combustion, gasification or liquefaction performance, the industry widely adopts physical or chemical treatment methods to upgrade lignite. Common processes cover multiple directions such as drying and dehydration, volatile matter removal and upgrading.

[0003] Among numerous upgrading technologies, high-frequency heating, with its significant advantages of rapid heating and high thermal efficiency, has become an ideal choice for large-scale drying and dehydration of low-rank coal, achieving efficient dehydration. However, high-frequency heating devices typically have a large volume and length. In actual production, lignite needs to be lifted and transported into the device for upgrading. Due to the large scale and complex structure of the entire upgrading system, the operating status of each component significantly affects the upgrading effect. Therefore, operators need to monitor and inspect the equipment's operating status in real time. However, since the equipment encompasses multiple subsystems such as conveying, heating, and control, the inspection scope is wide and the content is complex. A single comprehensive inspection takes a long time, which not only increases labor costs but also easily leads to missed or false inspections. If abnormal operation of key components is not detected in time, it will lead to a decline in the lignite upgrading effect, or even cause equipment failure or safety hazards, thus restricting the improvement of production efficiency and product quality. Utility Model Content

[0004] The purpose of this invention is to provide a comprehensive monitoring device for the high-frequency heating and upgrading process, so as to solve the problem mentioned in the background art that it is inconvenient for workers to monitor data and conduct field inspections during the lignite upgrading process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a comprehensive monitoring device for a high-frequency heating and upgrading process, comprising a mounting frame, a high-frequency heating rotary kiln fixedly placed on one side of the mounting frame, a hopper fixedly mounted on the outer surface of the mounting frame, and a screw conveyor feeder fixedly mounted on the outer surface of the hopper, the discharge end of the screw conveyor feeder being connected to the inlet of the high-frequency heating rotary kiln, and a temperature-controlled heating cabinet fixedly mounted on one side of the high-frequency heating rotary kiln, an infrared temperature measuring camera fixedly mounted on the outer surface of the mounting frame away from the hopper, the infrared temperature measuring camera facing the high-frequency heating rotary kiln, the height of the infrared temperature measuring camera being higher than the height of the hopper, a wireless signal transmission module fixedly mounted on the outer surface of the mounting frame near the ground, and the wireless signal transmission module being connected to the infrared temperature measuring camera, and a monitoring operating platform placed on one side of the mounting frame, and the monitoring operating platform being connected to the temperature-controlled heating cabinet.

[0006] Preferably, a monitoring camera is fixedly installed at one end of the mounting bracket near the infrared temperature measuring camera, and the monitoring camera faces the hopper. The monitoring camera is connected to a wireless signal transmission module.

[0007] By adopting the above technical solution, the images captured by the monitoring camera can be transmitted through the wireless signal transmission module to check the lignite fed into the hopper, to see if the lignite in the hopper has been used up, and also to check if there is any blockage inside the hopper, thus improving the convenience of the inspection.

[0008] Preferably, a smoke sensor is fixedly installed on the outer surface of the spiral lifting feeder at the end away from the mounting frame, and the smoke sensor is located above the feeding port of the high-frequency heating rotary kiln, and the smoke sensor is connected to a wireless signal transmission module.

[0009] Using the above technical solution, in the lignite upgrading process, the smoke sensor can serve as a key component for monitoring abnormal combustion of lignite inside the high-frequency heating rotary kiln. When lignite burns due to local overheating, abnormal oxygen content, or other reasons, the smoke sensor can detect the scattering of light by smoke particles or changes in ion current, thereby triggering an alarm signal and prompting operators to adjust heating parameters or shut down the machine for maintenance in a timely manner, thus avoiding excessive pyrolysis of lignite, equipment damage, or safety accidents caused by combustion.

[0010] Preferably, the high-frequency heating rotary kiln has a discharge port at the end away from the mounting frame, a fire observation hole is opened on the outer surface of the high-frequency heating rotary kiln, a detection probe is fixedly installed at the discharge port of the high-frequency heating rotary kiln, a harmful gas detection sensor is fixedly installed at the end of the high-frequency heating rotary kiln close to the detection probe, and an audible and visual alarm is provided on the outer surface of the harmful gas detection sensor, and the harmful gas detection sensor is connected to the detection probe.

[0011] Using the above technical solution, the internal condition of the high-frequency heating rotary kiln can be easily observed through the observation hole. At the same time, the gas inside the high-frequency heating rotary kiln after upgrading can be detected by the detection probe, so that the harmful gas detection sensor can immediately sound an alarm when toxic or harmful gases are detected.

[0012] Preferably, an adjustment signal transmission module is fixedly installed on the side surface of the high-frequency heating rotary kiln, and the adjustment signal transmission module is connected to a harmful gas detection sensor. A conveyor belt is provided at one end of the discharge port of the high-frequency heating rotary kiln.

[0013] By adopting the above technical solution, the parameters of the hazardous gas detection sensor can be adjusted by adjusting the signal transmission module, and the obtained data can be transmitted remotely by adjusting the signal transmission module, so that operators can know the data without coming here to check.

[0014] Preferably, a wireless signal receiving module is placed on the ground on one side of the monitoring console, and the wireless signal receiving module is connected to the monitoring console.

[0015] By adopting the above technical solution, the wireless signal receiving module can receive and adjust the data transmitted by the wireless signal transmission module, and then transmit all of this data to the monitoring console, allowing operators to understand the overall data simply by using the monitoring console.

[0016] Preferably, a projection display screen is fixedly installed on the outer surface of the monitoring console, an operation touch control screen is fixedly installed on one side of the outer surface of the monitoring console, and alarm buzzers are evenly distributed on the outer surface of the monitoring console.

[0017] Using the above technical solution, the images displayed by the monitoring camera and the infrared temperature measurement camera can be viewed through the projection screen. The temperature control cabinet can be remotely controlled and adjusted through the touch control screen. The alarm buzzer corresponds one-to-one with the temperature control cabinet, so that when the temperature of the high-frequency heating rotary kiln is too low, the alarm buzzer can be used to sound an alarm. At the same time, the alarm can also be sounded through the smoke sensor and the harmful gas detection sensor.

[0018] Compared with the prior art, the beneficial effects of this utility model are: This high-frequency heating and quality improvement process integrated monitoring device:

[0019] 1. The infrared temperature measurement camera can simultaneously detect the temperature and acquire images of the high-frequency heating rotary kiln. The signal is transmitted to the wired signal receiving module via a wireless signal transmission module. In conjunction with the connection between the temperature control heating cabinet and the monitoring console, the operator can remotely know the site conditions around the high-frequency heating rotary kiln. At the same time, the data measured by the infrared temperature measurement camera can be compared with the data transmitted from the temperature control heating cabinet, which improves the temperature accuracy of the high-frequency heating rotary kiln during operation. This eliminates the need for the operator to check and confirm the data of the temperature control heating cabinet one by one, bringing convenience to the operator's inspection and response.

[0020] 2. The use of surveillance cameras can transmit images of the hopper to the monitoring console in real time, allowing operators to know the remaining amount of lignite in the hopper and whether there is any blockage. This reduces the risk of lignite supply failure due to lack of material or blockage, and allows operators to promptly confirm the status of the hopper and take corresponding measures.

[0021] 3. The smoke sensor can detect whether the lignite being upgraded inside the high-frequency heated rotary kiln is burning. When the lignite is burning, the smoke produced will be captured by the smoke sensor and an alarm will be triggered. The harmful gas detection sensor can detect the gas produced during the upgrading process through the detection probe. When harmful gas is detected, an alarm can be triggered through the harmful gas detection sensor, and the alarm signal can be transmitted to the monitoring console by adjusting the signal transmission module, so that the detection personnel can take corresponding measures immediately or directly shut down the machine to reduce the abnormalities caused by the burning of lignite.

[0022] 4. The wireless signal receiving module can receive signals from the wireless signal transmission module and the adjustment signal transmission module to gather all the information together. The projection screen can project the images from the monitoring camera and the infrared temperature measurement camera. The touch control panel can be used to control and change the data of the temperature-controlled heating cabinet. The alarm buzzer can provide low-temperature alarms for the corresponding temperature-controlled heating cabinet and can also alarm on signals transmitted by the harmful gas detection sensor and the smoke sensor, allowing operators to understand the overall operating status of the device through the monitoring console.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] Please see Figure 1-6 This utility model provides a technical solution: a comprehensive monitoring device for a high-frequency heating and upgrading process, including a mounting frame 1. A high-frequency heating rotary kiln 6 is fixedly placed on the ground on one side of the mounting frame 1. A hopper 2 is fixedly installed on the outer surface of the mounting frame 1, and a screw conveyor feeder 3 is fixedly installed on the outer surface of the hopper 2. The discharge end of the screw conveyor feeder 3 is connected to the feed inlet of the high-frequency heating rotary kiln 6. A temperature control heating cabinet 7 is fixedly installed on the ground on one side of the high-frequency heating rotary kiln 6. An infrared temperature measuring camera 5 is fixedly installed on the outer surface of the mounting frame 1 away from the hopper 2, and the infrared temperature measuring camera 5 faces the high-frequency heating rotary kiln 6. The height of the infrared temperature measuring camera 5 is higher than the height of the hopper 2. A wireless signal transmission module 9 is fixedly installed on the outer surface of the mounting frame 1 near the ground, and the wireless signal transmission module 9 is connected to the infrared temperature measuring camera 5. A monitoring operation table 13 is placed on the ground on one side of the mounting frame 1, and the monitoring operation table 13 is connected to the temperature control heating cabinet 7.

[0032] By monitoring the connection between the control panel 13 and the temperature control heating cabinet 7 and using the infrared temperature measuring camera 5, operators can remotely monitor the heating status of the high-frequency heating rotary kiln 6 and reconfirm it through the infrared temperature measuring camera 5. They can also use the infrared temperature measuring camera 5 to view the surrounding area. The infrared temperature measuring camera 5 is fixed to the outer surface of the mounting frame 1, which greatly increases the height of the infrared temperature measuring camera 5, making the field of view wider and bringing convenience to the viewing of the surrounding environment. At the same time, the operating temperature of the high-frequency heating rotary kiln 6 can be rechecked through the infrared temperature measuring camera 5.

[0033] A monitoring camera 4 is fixedly installed on one end of the mounting bracket 1 near the infrared temperature measuring camera 5, and the monitoring camera 4 faces the hopper 2. The monitoring camera 4 is connected to the wireless signal transmission module 9.

[0034] The monitoring camera 4 can monitor and view the lignite fed into the hopper 2, and can know the remaining amount of lignite in the hopper 2 in real time. At the same time, when the lignite in the hopper 2 is blocked, it can be detected and dealt with in time, ensuring that the lignite is supplied to the high-frequency heating rotary kiln 6 for upgrading treatment in a timely manner, reducing the idle work and inconvenience caused by material shortage.

[0035] A smoke sensor 8 is fixedly installed on the outer surface of the spiral lifting feeder 3 away from the mounting frame 1. The smoke sensor 8 is located above the feeding port of the high-frequency heating rotary kiln 6 and is connected to the wireless signal transmission module 9.

[0036] The rotation of the screw conveyor feeder 3 evenly feeds the lignite stored in the hopper 2, ensuring that the lignite is always evenly discharged into the high-frequency heating rotary kiln 6. During the upgrading process of lignite in the high-frequency heating rotary kiln 6, when combustion occurs due to local overheating, abnormal oxygen content, or other reasons, smoke will be captured by the smoke sensor 8, triggering an alarm signal. This allows the operator to receive the alarm and adjust the heating parameters or shut down the machine for maintenance in a timely manner, avoiding safety accidents caused by excessive pyrolysis of lignite and equipment damage.

[0037] The high-frequency heating rotary kiln 6 has a discharge port at the end away from the mounting frame 1. The outer surface of the high-frequency heating rotary kiln 6 has a viewing hole. A detection probe 11 is fixedly installed at the discharge port of the high-frequency heating rotary kiln 6. A harmful gas detection sensor 10 is fixedly installed at the end of the high-frequency heating rotary kiln 6 close to the detection probe 11. The outer surface of the harmful gas detection sensor 10 is equipped with an audible and visual alarm. The harmful gas detection sensor 10 is connected to the detection probe 11.

[0038] The detection probe 11 can effectively detect the gas generated during the process of upgrading lignite in the high-frequency heating rotary kiln 6. When the detection probe 11 detects harmful gas, the harmful gas detection sensor 10 will sound an alarm to notify the staff of the abnormality and immediately shut down the machine to reduce the harm to personnel caused by harmful gas.

[0039] An adjustment signal transmission module 12 is fixedly installed on the side surface of the high-frequency heating rotary kiln 6, and the adjustment signal transmission module 12 is connected to the harmful gas detection sensor 10. A conveyor belt 18 is provided at one end of the discharge port of the high-frequency heating rotary kiln 6.

[0040] The detection data of the hazardous gas detection sensor 10 can be adjusted by adjusting the signal transmission module 12. At the same time, the data and alarms detected by the hazardous gas detection sensor 10 can be fed back to the monitoring console 13, allowing the operator to remotely know the data measured by the hazardous gas detection sensor 10 without having to come to the hazardous gas detection sensor 10. Meanwhile, the produced upgraded coal can be transported by the conveyor belt 18.

[0041] A wireless signal receiving module 14 is placed on the ground on one side of the monitoring console 13 and is connected to the monitoring console 13. A projection display screen 15 is fixedly installed on the outer surface of the monitoring console 13. An operation touch control screen 16 is fixedly installed on one side of the outer surface of the monitoring console 13. Alarm buzzers 17 are evenly arranged on the outer surface of the monitoring console 13.

[0042] The wireless signal receiving module 14 can receive data from the wireless signal transmission module 9 and the adjustment signal transmission module 12, and feed the received data back to the monitoring console 13. The images of the monitoring camera 4 and the infrared temperature measuring camera 5 can be displayed on the projection screen 15. The data of the temperature-controlled heating cabinet 7 can be remotely controlled and adjusted by operating the touch control screen 16. The alarm buzzer 17 can warn the temperature-controlled heating cabinet 7 one by one, so that the temperature-controlled heating cabinet 7 can alarm when it detects that the temperature of the high-frequency heating rotary kiln 6 in the corresponding section is too low. This allows the operator to know the fault point remotely without having to search and check each point. The fault point can be quickly located and checked. At the same time, the alarm buzzer 17 can also provide feedback on the alarms of the smoke sensor 8 and the harmful gas detection sensor 10.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
