Figure 2 This is a schematic diagram of the structure of the second type of dehumidification system provided in this embodiment of the present invention. Figure 3 This is a side view of the first type of moisture-venting pipe provided in this embodiment of the present invention, with reference to... Figures 1 to 3This utility model embodiment provides a dehumidification system 10, which includes a dehumidification fan module 100, a dehumidification pipe 200, a wind pressure detection module 300, and a control module 400. The dehumidification fan 100 is located inside the dehumidification pipe 200. The dehumidification fan module 100 includes an air supply unit 110, which includes an air supply receiving end 110a. The dehumidification pipe 200 includes a first end 210 and a second end 220, which are located within the dehumidification pipe. On both sides of the duct 200, the dehumidification duct 200 is connected to the dehumidification equipment 20 through the first end 210, and the air supply unit 110 is located at the first end 210; the air pressure detection module 300 is located on the inner wall of the dehumidification duct 200; the air pressure detection module 300 includes a first air pressure detection unit 310 and a second air pressure detection unit 320, the first air pressure detection unit 310 is located on the side of the second air pressure detection unit 320 closer to the first end 210, and the second air pressure detection unit 320 is located on the side of the first air pressure detection unit 20 closer to the first end 210. The pressure detection unit 310 is located on the side near the second end 220; the first air pressure detection unit 310 includes a first air pressure output end 310a, and the second air pressure detection unit 320 includes a second air pressure output end 320a; the control module 400 includes an air supply output end 400a, a first air pressure receiving end 400b, and a second air pressure receiving end 400c; the air supply output end 400a is connected to the air supply receiving end 110a, and the control module 400 controls the air supply unit 110 to provide air to the exhaust pipe 200. Wind force; the first wind pressure output terminal 310a is connected to the first wind pressure receiving terminal 400b, and the second wind pressure output terminal 320a is connected to the second wind pressure receiving terminal 400c. The control module 400 determines the blockage status of the exhaust pipe 200 based on the wind pressure difference detected by the wind pressure detection module 300. The distance between the first terminal 210 and the second terminal 220 is L0, and the distance between the first wind pressure detection unit 310 and the second wind pressure detection unit 320 is L1, satisfying that L1 / L0≥2 / 3.
[0039] Among them, reference Figure 1 and Figure 3 As shown, the dehumidification system 10 includes a dehumidification pipe 200, with a first end 210 and a second end 220 at its two ends. The first end 210 is connected to a dehumidification device 20, through which the gas generated by the dehumidification device 20 and impurities to be discharged are discharged. For example, the dehumidification device 20 can be an airflow-type yarn drying machine or similar equipment. The second end 220 can be connected to a dehumidification chamber (not specifically shown in the figure), or, if the gas discharged from the dehumidification device 20 is unpolluted, the second end 220 can be directly exposed to the external environment. This embodiment of the invention does not specifically limit the connection method of the second end 220. In other words, the first end 210 can be understood as the inlet of the dehumidification pipe 200, discharging the gas and impurities generated by the dehumidification device 20 into the pipe, and the second end 220 can be understood as the outlet of the dehumidification pipe 200.
[0040] Among them, reference Figure 1 and Figure 3 As shown, the dehumidification system 10 also includes a dehumidification fan module 100, which is installed inside the dehumidification pipe 200. The dehumidification fan module 100 can provide airflow to move floating impurities such as gas in the dehumidification system 10. Specifically, the dehumidification fan module 100 includes an air supply unit 110, which is located at the first end 210. The air supply unit 110 can help transmit the gas discharged by the dehumidification device 20 to the second end 220 through the first end 210, so that impurities such as gas can be discharged through the dehumidification pipe 200.
[0041] Among them, reference Figure 1 and Figure 3 As shown, the dehumidification system 10 also includes a wind pressure detection module 300, which is located on the inner wall of the dehumidification pipe 200. The wind pressure detection module 300 can detect the wind pressure value inside the dehumidification pipe 200. Specifically, gases or floating impurities discharged by the dehumidification device 20 through the dehumidification pipe 200 will deposit inside the dehumidification pipe 200. As the amount of deposited impurities increases, it will affect the discharge situation of the dehumidification pipe 200. For example, when the dehumidification device 20 is a tobacco-related device, tobacco dust and other particles in the dehumidification pipe 200 will enter the dehumidification pipe along with the moisture and deposit there, clogging the pipe. The wind pressure corresponding to a large amount of deposited impurities in the dehumidification pipe 200 is different from the wind pressure corresponding to a lack of deposited impurities. The wind pressure detection module 300 can detect the wind pressure in the dehumidification pipe 200 to determine whether there is any buildup in the dehumidification pipe 200.
[0042] For details, please refer to Figure 1 and Figure 3 As shown, the wind pressure detection module 300 includes a first wind pressure detection unit 310 and a second wind pressure detection unit 320. The first wind pressure detection unit 310 is located on the side of the second wind pressure detection unit 320 closer to the first end 210, and the second wind pressure detection unit 320 is located on the side of the first wind pressure detection unit 310 closer to the second end 220. In other words, the first wind pressure detection unit 310 and the second wind pressure detection unit 320 are located at different positions in the exhaust pipe 200, enabling the detection of wind pressure values at different locations within the exhaust pipe 200. Optionally, the wind pressure detection module 300 can be a barometer.
[0043] Among them, reference Figure 2As shown, the dehumidification system 10 also includes a control module 400. The control module 400 can be understood as a controller; for example, the control module 400 is a Programmable Logic Controller (PLC). A PLC is a digital processing controller with a microprocessor used for automated control. Further, refer to... Figure 2 As shown, the control module 400 includes an air supply output terminal 400a, and the air supply unit 110 includes an air supply receiving terminal 110a. The air supply output terminal 400a is connected to the air supply receiving terminal 110a. The control module 400 can control the air supply unit 110 to provide airflow to the exhaust duct 200. (Reference) Figure 2 As shown, the control module 400 also includes a first wind pressure receiving end 400b and a second wind pressure receiving end 400c. The first wind pressure detection unit 310 includes a first wind pressure output end 310a, and the second wind pressure detection unit 320 includes a second wind pressure output end 320a. The first wind pressure output end 310a is connected to the first wind pressure receiving end 400b, and the second wind pressure output end 320a is connected to the second wind pressure receiving end 400c. Therefore, the control module 400 is connected to the first wind pressure detection unit 310 and the second wind pressure detection unit 320 respectively. The control module 400 can compare the wind pressure value detected by the first wind pressure detection unit 310 and the wind pressure value detected by the second wind pressure detection unit 320, and then determine the blockage status of the exhaust pipe 200.
[0044] For example, refer to Figure 1As shown, the first wind pressure detection unit 310 and the second wind pressure detection unit 320 are located at different positions in the drainage pipe 200, with the first wind pressure detection unit 310 closer to the inlet of the drainage pipe 200 and the second wind pressure detection unit 320 closer to the outlet of the drainage pipe 200. The first wind pressure detection unit 310 is connected to the control module 400, which can obtain the wind pressure value detected by the first wind pressure detection unit 310; the second wind pressure detection unit 320 is also connected to the control module 400, which can obtain the wind pressure value detected by the second wind pressure detection unit 320. If the drainage pipe 200 is not blocked, the difference between the air pressure value detected by the first air pressure detection unit 310 and the air pressure value detected by the second air pressure detection unit 320 is very small or zero; for example, the difference between the two air pressure values is less than or equal to a preset difference. If the drainage pipe 200 is blocked, the difference between the air pressure value detected by the first air pressure detection unit 310 and the air pressure value detected by the second air pressure detection unit 320 is large; for example, the difference between the two air pressure values is greater than a preset difference. Thus, the control module 400 can compare the preset difference with the actual air pressure difference to determine whether the drainage pipe 200 is blocked. It should be noted that the preset difference for determining whether the drainage pipe 200 is blocked can be differentiated according to different diameters, lengths, etc., meaning the judgment standard can be adaptively adjusted according to actual needs.
[0045] By setting up a first air pressure detection unit 310 and a second air pressure detection unit 320, that is, by setting up multiple devices to detect air pressure, more accurate air pressure acquisition of the exhaust pipe 200 can be ensured. Furthermore, the control module 400 is connected to the air pressure detection devices at two different locations, and the internal blockage status of the exhaust pipe 200 is judged based on the difference in air pressure values detected by the two devices, achieving a more flexible and accurate judgment.
[0046] In other words, the dehumidification system provided in this embodiment of the invention determines the blockage status of the dehumidification pipe by detecting the air pressure inside the pipe. Specifically, at least two devices capable of detecting air pressure are added to the dehumidification pipe 200 and connected to the control module. The blockage status of the dehumidification pipe can be determined based on the difference in air pressure values detected by multiple air pressure detection devices.
[0047] Furthermore, in the exhaust pipe 200, impurities such as gas discharged from the exhaust device 20 are prone to blockage in the first half of the exhaust pipe 200, that is, near the first end 210. Therefore, in order to ensure a more accurate judgment of this blockage, it is necessary to adjust the positions of the first wind pressure detection unit 310 and the second wind pressure detection unit 320, so that one of the first wind pressure detection unit 310 and the second wind pressure detection unit 320 is set in a position where blockage is likely to occur, and the other is set in a position where blockage is unlikely to occur.
[0048] For details, please refer to Figure 1 The distance between the first end 210 and the second end 220 is L0, and the distance between the first wind pressure detection unit 310 and the second wind pressure detection unit 320 is L1, satisfying L1 / L0≥2 / 3. This can be understood as a larger distance difference between the first wind pressure detection unit 310 and the second wind pressure detection unit 320, ensuring that the wind pressure values collected by both are more reasonable and reliable. Specifically, the specific spacing between the first wind pressure detection unit 310 and the second wind pressure detection unit 320 is related to the overall length of the exhaust pipe 200.
[0049] In summary, this utility model embodiment provides a dehumidification system. A wind pressure detection module is installed in the dehumidification pipe. The wind pressure detection module includes a first wind pressure detection unit and a second wind pressure detection unit. Both the first and second wind pressure detection units transmit the detected wind pressure values to a control module. The control module can determine whether there is a blockage in the dehumidification system based on the difference between the two wind pressure values. If there is a blockage, the difference in wind pressure values will be significantly different from if there is no blockage. Furthermore, to ensure that the wind pressure values provided to the control module by the first and second wind pressure detection units are more reasonable for judging the blockage, the distance between the first and second wind pressure units is adjusted. The distance between the first and second ends is L0, and the distance between the first and second wind pressure detection units is L1, satisfying L1 / L0≥2 / 3. This ensures a more accurate understanding of the blockage status of the dehumidification pipe based on the first and second wind pressure detection units.
[0050] Continue to refer to Figure 1 and Figure 3 As shown, along the extension direction of the drainage pipe 200, the first wind pressure detection unit 310 and the second wind pressure detection unit 320 at least partially overlap.
[0051] Further reference Figure 1 and Figure 3As shown, along the extension direction of the exhaust pipe 200, the first air pressure detection unit 310 and the second air pressure detection unit 320 at least partially overlap. In other words, if the extension direction of the exhaust pipe 200 is horizontal, then the first air pressure detection unit 310 and the second air pressure detection unit 320 are on the same horizontal line. This ensures that the air pressure values detected by the first air pressure detection unit 310 and the second air pressure detection unit 320 are more accurate, and avoids errors caused by positional factors.
[0052] Figure 4 This is a schematic diagram of the third type of dehumidification system provided in this embodiment of the present invention. Figure 5 This is a side view of the second type of moisture-venting pipe provided in this embodiment of the present invention. Figure 6 This is a schematic diagram of the fourth type of dehumidification system provided in this embodiment of the present invention, for reference. Figures 4 to 6 The dehumidification system 10 also includes a wind speed detection module 500; the wind speed detection module 500 is located on the inner wall of the dehumidification pipe 200, and the wind speed detection module 500 includes a wind speed output end 500a; the control module 400 includes a wind speed receiving end 400d; the wind speed output end 500a and the wind speed receiving end 400d are connected, and the control module 400 determines the blockage status of the dehumidification pipe 200 based on the wind speed detected by the wind speed detection module 500.
[0053] Further reference Figures 4 to 6 The ventilation system 10 also includes a wind speed detection module 500, which is also installed on the inner wall of the ventilation pipe 200. The wind speed detection module 500 can detect the wind speed value inside the ventilation pipe 200. Furthermore, the control module 400 can combine the acquired wind pressure difference and wind speed value to make a more accurate judgment on the blockage of the ventilation pipe 200. Optionally, the wind speed detection module 500 can be an anemometer.
[0054] For details, please refer to Figure 5 As shown, the wind speed detection module 500 includes a wind speed output terminal 500a, and the control module 400 includes a wind speed receiving terminal 400d; the wind speed output terminal 500a and the wind speed receiving terminal 400d are connected, and the control module 400 determines the blockage status of the dehumidification pipe 200 based on the wind speed detected by the wind speed detection module 500.
[0055] For example, the control module 400 can compare the wind speed values detected by the wind speed detection module 500 at different times, and combine the wind pressure difference with the wind speed value to comprehensively determine the blockage status of the drainage pipe 200. Blockage in the drainage pipe 200 is not instantaneous, but occurs over a period of time. If there is a blockage, the accumulated deposits in the drainage pipe 200 result in higher wind pressure, and thus higher wind speed. If there is no blockage, the wind pressure in the drainage pipe 200 is lower, and thus lower wind speed.
[0056] Continue to refer to Figure 4 The distance between the wind speed detection module 500 and the first wind pressure detection unit 310 is less than the distance between the wind speed detection module 500 and the second wind pressure detection unit 320.
[0057] For details, please refer to Figure 4 Along the extension direction of the drainage pipe 200, the distance between the wind speed detection module 500 and the first wind pressure detection unit 310 is denoted as λLa, and the distance between the wind speed detection module 500 and the second wind pressure detection unit 320 is denoted as Lb, where λLa < Lb. The first wind pressure detection unit 310 is closer to the inlet of the drainage pipe 200 than the second wind pressure detection unit 320, and the location of the first wind pressure detection unit 310 is more prone to sediment accumulation and blockage compared to the location of the second wind pressure detection unit 320.
[0058] To determine the wind speed in the exhaust pipe 200, the wind speed detection module 500 is positioned closer to the first wind pressure detection unit 310. This can be understood as placing the wind speed detection module 500 near a location in the exhaust pipe 200 prone to blockage. This ensures that when the exhaust pipe 200 becomes blocked, the wind speed detection module 500 will show a more noticeable change in wind speed, leading to a more accurate assessment of the blockage status of the exhaust system 10.
[0059] Continue to refer to Figure 4 and Figure 5 Along the extension direction of the drainage pipe 200, the first wind pressure detection unit 310 and the second wind pressure detection unit 320 overlap at least partially, and the first wind pressure detection unit 310 and the wind speed detection module 500 overlap at least partially.
[0060] Further reference Figure 4 and Figure 5 As shown, along the extension direction of the exhaust pipe 200, the first air pressure detection unit 310 and the second air pressure detection unit 320 at least partially overlap. In other words, if the extension direction of the exhaust pipe 200 is horizontal, then the first air pressure detection unit 310 and the second air pressure detection unit 320 are on the same horizontal line. This ensures that the air pressure values detected by the first air pressure detection unit 310 and the second air pressure detection unit 320 are more accurate, and avoids errors caused by positional factors.
[0061] With the addition of a wind speed detection module 500, refer to Figure 4 and Figure 5As shown, along the extension direction of the exhaust pipe 200, the first wind pressure detection unit 310 and the wind speed detection module 500 at least partially overlap. In other words, if the extension direction of the exhaust pipe 200 is horizontal, then the first wind pressure detection unit 310 and the wind speed detection module 500 are on the same horizontal line. This ensures that the structure for detection by the first wind pressure detection unit 310, the second wind pressure detection unit 320, and the wind speed detection module 500 is more reliable and avoids errors caused by positional factors.
[0062] Continue to refer to Figure 4 and Figure 6 The dehumidification fan module 100 includes an exhaust unit 120, which includes an exhaust receiving end 120a. The exhaust unit 120a is located at the second end 220. The control module 400 includes an exhaust output end 400e. The exhaust output end 400e is connected to the exhaust receiving end 120a. The control module 400 controls the exhaust unit 120 to exhaust air from the dehumidification pipe 200.
[0063] Among them, reference Figure 4 As shown, the dehumidification fan module 100 also includes an exhaust unit 120, which is located at the second end 220. The exhaust unit 120 helps to expel gases and other gases from the dehumidification pipe 200 outside the pipe. Further, refer to... Figure 6 As shown, the exhaust unit 120 includes an exhaust receiving end 120a, and the control module 400 includes an exhaust output end 400e. The exhaust output end 400e is connected to the exhaust receiving end 120a, and the control module 400 is connected to the exhaust unit 120. The control module 400 can control the exhaust unit 120 to exhaust the moisture duct 200 more quickly, thereby ensuring the stability of the moisture duct 200.

Figure 8 This is a structural schematic diagram of the sixth type of dehumidification system provided in this embodiment of the present invention, for reference. Figure 7 and Figure 8 The dehumidification system 10 also includes an alarm module 600, which includes an alarm signal receiver 600a; the control module 400 includes an alarm signal output terminal 400f, which is connected to the alarm signal receiver 600a.
[0065] Further reference Figure 7 and Figure 8As shown, the ventilation system 10 also includes an alarm module 600, which includes a warning signal receiver 600a and a control module 400, which includes a warning signal output terminal 400f. The warning signal output terminal 400f is connected to the warning signal receiver 600a, meaning that the alarm module 600 is connected to the control module 400. When the ventilation pipe 200 is blocked, the control module 400 can control the alarm module 600 to issue a warning.
[0066] Optionally, the control module 400 can also be connected to a human-machine interface (not specifically shown in the figure), and the alarm module 600 can be integrated into the human-machine interface for alerting. Alternatively, the alarm module 600 can be placed outside the exhaust pipe 200, etc. The specific location of the alarm module 600 can be adjusted adaptively according to requirements.
[0067] Optionally, the alarm module may include a light warning unit and / or an audible warning unit.
[0068] Furthermore, the alarm module may include a light warning unit, which can indicate a blockage by flashing lights, such as flashing different colors or different frequencies of light. Furthermore, the alarm module may include an sound warning unit, such as using different beeping sounds to indicate a blockage.
[0069] Continue to refer to Figure 7 and Figure 8 The dehumidification system 10 also includes an image acquisition module 700, which includes an image signal output terminal 700a; the control module 400 includes an image signal receiving terminal 400g, and the image signal output terminal 700a is connected to the image signal receiving terminal 400g.
[0070] Further reference Figure 7 and Figure 8 As shown, the dehumidification system 10 also includes an image acquisition module 700. The image acquisition module 700 can acquire images of the interior of the dehumidification pipe 200 to determine whether there is a blockage. Specifically, the image acquisition module 700 includes an image signal output terminal 700a, and the control module 400 includes an image signal receiving terminal 400g. The image signal output terminal 700a is connected to the image signal receiving terminal 400g, and the control module 400 is connected to the image acquisition module 700. It can determine the blockage based on the image information acquired by the image acquisition module 700.
[0071] Optionally, the image acquisition module may include a camera or a LiDAR.
[0072] Furthermore, the image acquisition module may include a camera, which can directly acquire images. However, the internal space of the drainage pipe 200 is limited, so the camera needs to be miniaturized. Furthermore, the image acquisition module may also include a lidar unit, which can determine the blockage status within the drainage pipe 200 by combining the emission and reception of light.
