Description

Technical Field

[0001] This utility model relates to the field of tobacco processing equipment technology, and in particular to a process pipeline detection component. Background Technology

[0002] In existing tobacco processing, tobacco flows through process pipelines, passing sequentially through different processing machines. The entire process requires maintaining a sealed pipeline to prevent external environmental substances from affecting the process. This is especially true for the section of process pipeline from the tangential separator to the dual dust collector, where temperatures can reach 280°C due to the influence of upstream equipment. Under such high temperatures, if the seal within the process pipeline is compromised, it could potentially lead to a safety accident. However, if a compromised seal is detected promptly and appropriate preventative measures are taken, the safety risk can be significantly reduced.

[0003] In existing technologies, no additional protective designs are implemented for this section of the process pipeline. Therefore, safety risks arising in this section of the process pipeline cannot be detected in a timely manner. Utility Model Content

[0004] This invention provides a process pipeline inspection component to solve the problem that safety risks in process pipelines cannot be detected in a timely manner in the prior art.

[0005] This utility model provides a process pipeline inspection component, including: The pipeline has one end connected to a tangential separator and the other end connected to a dual dust collector; A monitoring device is installed through the wall of the pipeline and is used to monitor the oxygen content inside the pipeline.

[0006] According to the present invention, a process pipeline inspection component is provided. The monitoring device includes a detection probe and a display. The detection probe is electrically connected to the display. The detection probe is located inside the pipeline and is used to monitor the oxygen content inside the pipeline. The display is located outside the pipeline and is used to display the detection result of the detection probe.

[0007] According to the process pipeline inspection component provided by this utility model, the monitoring device further includes an alarm device, which is electrically connected to the display and is used to alarm the detection result of the detection probe.

[0008] According to the process pipeline detection component provided by this utility model, the warning value of the alarm device is that the oxygen content in the pipeline reaches 12%.

[0009] According to the present invention, a process pipeline detection component is provided, wherein the monitoring device further includes a filter screen, which is sleeved on the detection probe for filtering dust.

[0010] According to the present invention, a process pipeline inspection component is provided, wherein the inspection probe is inserted into the pipeline to a depth between 1 cm and 1 cm.

[0011] According to the present invention, a process pipeline inspection component is provided in which the inspection probe sends an analog signal of 4 to 20 mA to the display.

[0012] According to the present invention, a process pipeline inspection component is provided, which further includes a sealing ring connected between the monitoring device and the pipeline.

[0014] According to the present invention, a process pipeline inspection component is provided, which includes multiple monitoring devices, all of which are distributed on the pipeline.

[0015] This utility model provides a process pipeline inspection component that connects a tangential separator and a dual dust collector via a pipeline, thus posing a safety risk within the pipeline. Therefore, this application includes a monitoring device installed on the pipeline to monitor the internal state and data. Because the temperature inside the pipeline is high and it contains flammable materials such as dust and tobacco, the risk of combustion and explosion is high. Given the already sufficient temperature and flammable materials inside the pipeline, the risk of combustion and explosion increases significantly when oxygen is abundant. Therefore, the monitoring device in this application is used to monitor the oxygen content within the pipeline. Real-time monitoring of the oxygen content allows for real-time monitoring of safety risks, enabling timely detection and early warning before risks materialize, thereby allowing for proactive risk mitigation.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] The following is combined Figure 1 This invention describes a process pipeline inspection component, comprising a pipeline 1 and a monitoring device 4. One end of the pipeline 1 is connected to a tangential separator 2, and the other end is connected to a dual dust collector 3. The monitoring device 4 is installed through the pipe wall of the pipeline 1 and is used to monitor the oxygen content within the pipeline 1.

[0021] like Figure 1 As shown, pipe 1 connects the tangential separator 2 to the dual dust collector 3. Pipe 1 is primarily used for gas flow, therefore, it is preferably a circular pipe. Circular pipes offer advantages such as high airtightness, low installation costs, and high durability. Due to their uniformly distributed cross-section and circular structure, circular ventilation ducts possess strong resistance to pressure and deformation. This allows them to withstand greater external forces and pressures during use, extending their service life. Simultaneously, circular pipes exhibit lower wind resistance and friction loss, reducing the risk of pipe wear and blockage. Therefore, in this embodiment, using a circular pipe 1 is more economical and practical.

[0022] like Figure 1 As shown, the tangential separator 2 is used to separate tobacco shreds and soot. The first stage of separation in the tangential separator 2 typically employs cyclone separation. When the mixture containing tobacco shreds and soot enters the tangential separator 2, due to the rotational motion of the cyclone separator, the heavier soot particles are thrown against the separator wall by inertia and settle, while the lighter tobacco shreds continue to rise with the airflow. This separation method effectively utilizes the density difference between different materials to achieve preliminary separation. In the second stage of separation, the tangential separator 2 further separates the tobacco shreds and soot by utilizing the difference in suspension velocity. By controlling the speed and direction of the airflow, the suspension velocity of the tobacco shreds is made less than the airflow velocity, causing it to rise, while the soot settles because its suspension velocity is greater than the airflow velocity. This process further purifies the tobacco shreds and reduces the contamination of soot.

[0023] The soot separated from the tobacco enters pipe 1 with the airflow, and then flows through pipe 1 to the dual dust collector 3, where the soot is removed. Therefore, soot particles exist within pipe 1, and these soot particles are combustible.

[0024] Meanwhile, the overall temperature is already relatively high in the processes preceding the tangential separator 2. After further processing by the tangential separator 2, the overall temperature increases further, causing the temperature inside pipe 1 to reach 280℃ or even higher. Under such conditions, the smoke and dust inside pipe 1 may pose a risk of combustion or explosion. Combustion requires three necessary conditions: combustible material, oxidizer, and ignition source. The combustible material is the smoke and dust, the ignition source is the high temperature of 280℃ inside pipe 1, and there is a significant probability of combustion when there is sufficient oxidizer in pipe 1. The oxidizer in pipe 1 is oxygen, which supports the combustion of the smoke and dust, thus causing it to burn.

[0025] During normal production and processing, the oxygen content in pipe 1 is low, so there is no risk of combustion. However, when a leak occurs between tangential separator 2, pipe 1, and dual dust collector 3, air with a higher oxygen content will enter pipe 1, thereby increasing the oxygen content in pipe 1 and creating a risk of combustion.

[0026] Therefore, in this embodiment, a monitoring device 4 is installed on the pipe 1. The monitoring device 4 is inserted into the pipe 1 to monitor the data inside the pipe 1. Because oxygen in the pipe 1 is an important factor that poses a combustion risk, the monitoring device 4 detects the oxygen content inside the pipe 1. When the oxygen content in the pipe 1 reaches a certain value, it may cause the smoke to ignite. Therefore, the monitoring device 4 needs to continuously monitor the oxygen content in the pipe 1. Once the oxygen content is about to rise to a level that poses a combustion risk, the monitoring device 4 will issue an advance warning based on the detection result. Therefore, in this embodiment, the monitoring device 4 needs to be installed on the pipe 1 so that the monitoring device 4 can monitor through one end located inside the pipe 1 and display the data through the other end located outside the pipe 1.

[0027] During normal operation, the monitoring device 4 performs real-time monitoring and displays the detection results. By observing the detection results displayed on the monitoring device 4, the operator can understand the oxygen content of the pipeline 1 and take timely preventive measures when the oxygen content rises, thereby reducing the risk of combustion.

[0028] In this embodiment, by installing a monitoring device 4 on the pipeline 1 and monitoring the oxygen content in the pipeline 1 through the monitoring device 4, it is possible to detect the rise in oxygen content in a timely manner, thereby providing a warning before the risk of combustion occurs. This helps operators to detect potential safety risks in advance and avoid them in advance.

[0029] In one embodiment, the monitoring device 4 includes a detection probe 41 and a display 42. The detection probe 41 is electrically connected to the display 42. The detection probe 41 is located inside the pipe 1 and is used to monitor the oxygen content inside the pipe 1. The display 42 is located outside the pipe 1 and is used to display the detection result of the detection probe 41. In one embodiment, the detection probe 41 sends an analog signal of 4 to 20 mA to the display 42.

[0030] In this embodiment, the monitoring device 4 includes a detection probe 41 and a display 42, which are electrically connected to each other. Because the monitoring device 4 is installed inside the pipe 1, the detection probe 41 is positioned inside the pipe 1 to monitor the oxygen content within the pipe 1. The end of the monitoring device 4 equipped with the display 42 is positioned outside the pipe 1 to prevent the pipe wall from obstructing the display, thus allowing the operator to more easily observe the results shown on the display 42.

[0031] When the tangential separator 2 starts working, the detection probe 41 also operates, continuously monitoring the gas content within the pipeline 1. Specifically, the detection probe 41 can maintain continuous monitoring, improving safety. Simultaneously, the detection frequency of the detection probe 41 can be segmented according to time. For example, the frequency of the detection probe 41 can be set to one minute, detecting once every minute, thereby reducing resource consumption, saving energy, and improving economic efficiency. Each time the detection probe 41 detects, it transmits the detected signal to the display 42, which displays the detection result digitally. In this embodiment, the detection probe 41 transmits data using an analog signal of 4 to 20 mA, which improves the anti-interference capability during data transmission and ensures the stability of data transmission.

[0032] In one embodiment, the monitoring device 4 further includes an alarm device 43, which is electrically connected to the display 42 and is used to alarm the detection result of the detection probe 41.

[0033] like Figure 1As shown, this embodiment also includes an alarm device 43. Because the alarm device 43 needs to more conveniently transmit alarm signals to the operator, it is positioned closer to the display 42. The alarm device 43 is also positioned outside the pipe 1, thus preventing the pipe 1 from obstructing the alarm signal. Generally, the alarm device 43 can trigger an alarm using both sound and light signals, with a red light typically used. The specific alarm method can be set according to the actual processing environment and is not limited in this application.

[0034] In one embodiment, the warning value of the alarm device 43 is that the oxygen content in the pipeline 1 reaches 12%.

[0035] Within pipe 1, airflow carries away the smoke and dust. This airflow already contains oxygen, although under normal circumstances the oxygen content is low and insufficient to catalyze combustion. Normally, the oxygen content in the airflow is around 10%. Therefore, in this embodiment, the warning value for the alarm device 43 is set to an oxygen content of 12%. When the detection probe 41 detects an oxygen content greater than or equal to 12% in pipe 1, it first transmits the detection result to the display 42 via an electrical signal. Since the display 42 is electrically connected to the alarm device 43, it then transmits the detection result back to the alarm device 43 via an electrical signal. Upon receiving the detection signal indicating an oxygen content greater than or equal to 12% in pipe 1, the alarm device 43 immediately sounds an alarm to alert the operator, enabling them to address safety risks more promptly and better mitigate them.

[0036] In one embodiment, the monitoring device 4 further includes a filter 44, which is fitted onto the detection probe 41 and is used to filter dust.

[0037] like Figure 1As shown, in this embodiment, a filter 44 is provided over the detection probe 41, completely covering and protecting the probe 41. Because the detection probe 41 is located inside the pipe 1 to monitor the oxygen content within the pipe 1, and the airflow inside the pipe 1 carries smoke and dust (solid particles), when the detection probe 41 is positioned inside the pipe 1 for detection, the smoke and dust may be carried towards the probe 41 by the airflow and adhere to its surface. When the smoke and dust adhere to the surface of the probe 41, it obstructs the contact between the probe 41 and the airflow, affecting the detection results and leading to inaccurate results. In this embodiment, the filter 44 protects the detection probe 41, isolating the smoke and dust outside the probe 41 and preventing its influence. Furthermore, the filter 44 only filters solid particles such as smoke and dust, not gaseous particles like airflow, so it does not affect the detection results of the probe 41.

[0038] In one embodiment, the detection probe 41 is inserted into the pipe 1 to a depth between 30 cm and 50 cm. Figure 1 As shown, based on the diameter of pipe 1 and the content distribution of each component in the airflow, in this embodiment, the insertion depth of the detection probe 41 into pipe 1 is set to 50 cm, that is, the distance between the detection probe 41 and the inner wall of pipe 1 on the side near the display 42 is 50 cm. This position is closer to the center of pipe 1, making the detection result of the detection probe 41 more accurate, while also preventing the monitoring device 4 from being too long.

[0039] In one embodiment, the process pipeline inspection assembly further includes a sealing ring connected between the monitoring device 4 and the pipeline 1. In this embodiment, because the monitoring device 4 passes through the pipeline 1, an opening needs to be made in the pipeline 1 to house the monitoring device 4. Since gas flows through the pipeline 1, and the gas carries dust, the sealing ring is needed to seal the opening in the pipeline 1 to prevent airflow leakage. After placing the monitoring device 4 in the opening in the pipeline 1, the sealing ring seals the connection between the monitoring device 4 and the pipeline 1, improving the airtightness.

[0040] In one embodiment, the monitoring device 4 is installed on the side of the pipeline 1 near the tangential separator 2. Because the airlock below the tangential separator 2 is a high-risk area for leaks, improper or loose connections can easily cause leaks, leading to an increase in oxygen content within the pipeline 1. Therefore, in this embodiment, the monitoring device 4 is installed on the side of the pipeline 1 near the tangential separator 2, allowing for faster detection of changes in oxygen content when a leak occurs.

[0041] In one embodiment, the process pipeline inspection assembly includes multiple monitoring devices 4, which are evenly distributed on the pipeline 1. Although the side near the tangential separator 2 is a high-risk area for leakage, other areas on the entire pipeline 1 are also at risk of leakage. Therefore, by arranging multiple monitoring devices 4 on the pipeline 1, leakage at other locations on the pipeline 1 can be detected more quickly.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
