Terms (such as those defined in commonly used dictionaries) shall be interpreted as having the same meaning as in their contextual meaning in the relevant technical field and shall not be construed as having an idealized or overly formal meaning, unless clearly defined in the various embodiments of this application.

[0020] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0021] Figure 1 A schematic diagram of a moisture detection device 100 according to an embodiment of this application is shown. Exemplarily, the moisture detection device 100 includes a cavity 101, a high-level detection switch 102, a moisture detection sensor 103, and a gate valve 104. The high-level detection switch 102 is disposed at the top of the cavity 101, the moisture detection sensor 103 is disposed on one side wall of the cavity 101, and the gate valve 104 is slidably disposed below the cavity 101.

[0022] In this embodiment, the cavity 101 serves as a space for containing the target material, used to hold the target material transported by the material transport pipeline, buffering the target material for a period of time to allow the moisture detection sensor 103 to obtain detection data more accurately. When the moisture detection sensor 103 is in the detection mode for detecting the moisture of the target material in the cavity 101, the slide gate valve 104 is in the closed state; when the high material level detection switch 102 detects that the target material has accumulated to the top of the cavity 101, and the corresponding high material signal is maintained for a preset time, the slide gate valve 104 is in the open state, and the target material is discharged from the cavity 101.

[0023] Exemplary, the material transfer pipeline is a conduit or channel structure that transfers target materials to target equipment. Target equipment includes, but is not limited to, silos, pellet mills, etc., and target materials include, but are not limited to, grains, feed, chemical raw materials, etc.

[0024] In one embodiment, the high-level detection switch 102 is used to detect whether the material in the cavity 101 has reached the top of the cavity 101, i.e., the high-level state. When the material rises to the position of the high-level detection switch 102, it outputs a high-material signal, which indicates that the target material has reached the top of the cavity 101 and also indicates that there is material in the cavity 101. When the target material has not reached the position of the high-level detection switch 102, the high-material signal is not triggered. The high-level detection switch 102 includes, but is not limited to, capacitive level switches, mechanical level switches, etc. The moisture detection sensor 103 is the core of the integrated tooling and is mainly used to detect the moisture content of the material in the cavity 101 through the capacitance method.

[0025] It is understandable that when the high material level detection switch 102 outputs a high material signal, the material accumulates to the top of the cavity 101. At this time, the material inside the cavity 101 is relatively dense and highly compacted. Using the material moisture detected within the high material signal time as a reference ensures the accuracy and reliability of the moisture detection information and provides a reference time value for accurate moisture measurement, thereby reducing moisture detection errors. This ensures accurate measurement of the material state and transmission of the material moisture value even when material is present in the cavity 101, guaranteeing the accuracy and reliability of the information.

[0026] In one embodiment, such as Figure 2 As shown, the moisture detection device 100 also includes a slide gate pneumatic valve 105. Exemplarily, the slide gate pneumatic valve 105 is used to connect to a slide gate valve 104 to control the opening and closing of the slide gate valve 104. The slide gate pneumatic valve 105 uses the switching of compressed air intake direction to drive a cylinder piston to perform linear motion, thereby causing the gate of the slide gate valve 104 to insert or retract into the material channel at the bottom of the cavity 101, thus controlling the slide gate valve 104. Specifically, the closed state of the slide gate valve 104 is when the gate is inserted into the material channel at the bottom of the cavity 101 to prevent material from being discharged from the cavity 101; the open state of the slide gate valve 104 is when the gate retracts from the material channel at the bottom of the cavity 101 to allow material to be discharged from the cavity 101.

[0027] In this embodiment, during material flow, the moisture detection sensor 103 is easily affected by particle disturbance and density fluctuations, leading to inaccurate moisture measurement. Moisture measurement is only accurate when the material is completely still and uniformly packed. The slide gate valve 104 controls the flow and stillness of the material, allowing the moisture detection sensor 103 to detect moisture even when stationary, thus improving measurement accuracy.

[0028] In one embodiment, the moisture detection device 100 further includes a vibration device 106. Exemplarily, the vibration device 106 is positioned above the slide gate valve 104. The vibration device 106 is used to agitate the target material within the cavity 101 to assist in the discharge of the target material. In this embodiment, the vibration device 106 is a gas vibration device 106. When the slide gate valve 104 opens to discharge material, it applies vibration energy to the inner wall of the cavity 101 or the material through periodic or pulsed gas impacts, disrupting the friction and adhesion between materials, preventing material from adhering to the wall or causing blockages, thereby promoting smooth material discharge.

[0029] In another embodiment, the moisture detection device 100 further includes a vibration valve 107. Exemplarily, the vibration valve 107 is used to connect to the vibration device 106 to control the start and stop of the vibration device 106. In this embodiment, the vibration valve 107 is a vibration air valve, which is an electromagnetically controlled gas on / off switch used to control whether compressed air is supplied to the gas vibration device 106. When the vibration air valve is open, the air source is connected, and the vibration device 106 operates; when the vibration air valve is closed, the air source is cut off, and the vibration device 106 stops.

[0030] In one embodiment, the moisture detection device 100 further includes a controller 108. Exemplarily, the controller 108 is positioned below the slide gate valve 104 and is used to connect to the high-level detection switch 102, the vibration valve 107, and the slide gate pneumatic valve 105, respectively. In this embodiment, the controller 108 receives the high-level signal output by the high-level detection switch 102, determines the duration of the high-level signal based on an internal timer, and after the high-level signal has lasted for a preset time, the controller 108 sends control commands to the slide gate pneumatic valve 105 and the vibration valve, causing the slide gate valve 104 to open and the vibration device 106 to begin agitating the target material within the cavity 101, thus facilitating the smooth discharge of the target material.

[0031] By way of example, controller 108 includes, but is not limited to, programmable logic controllers, microcontrollers, central processing units (CPUs), etc. The preset time can be set according to the actual application, for example, the preset time includes, but is not limited to, 15 seconds, 16 seconds, and 17 seconds, etc.

[0032] In one embodiment, the controller 108 can be used to set the moisture detection time. When the material moisture detection begins, the gate valve 104 is closed, and the moisture detection time is recorded via a timer. When the moisture detection time exceeds a first preset duration, and the gate valve 104 remains closed, the gate valve 104 is opened to activate the vibration device 106. After the vibration device 106 operates for a second preset duration, the vibration device 106 is turned off. The first and second preset durations can be set according to the actual application. For example, the first preset duration includes, but is not limited to, 7 minutes, 8 minutes, 9 minutes, etc., and the second preset duration includes, but is not limited to, 25 seconds, 30 seconds, 35 seconds, etc.

[0033] In one embodiment, such as Figure 3 As shown, the moisture detection device 100 also includes a variable diameter structure 109 and a fixing component 110. Exemplarily, the variable diameter structure 109 is fixedly connected to the cavity 101, and the fixing component 110 is fixedly connected to the variable diameter structure 109 and the material transfer pipe; the variable diameter structure 109 is used to change the inner diameter of the material transfer pipe. In this embodiment, the variable diameter structure 109 is a transition section connecting material transfer pipes of different diameters with the detection cavity 101, achieving a smooth transition from the inner diameter of the pipe to the inlet size of the cavity 101, ensuring rapid material entry into the cavity 101. The fixing component 110 firmly connects the moisture detection device 100 to the material transfer pipe, ensuring the mechanical stability of the overall structure under conditions such as vibration and pressure fluctuations.

[0034] In one embodiment, the inner diameter of the material conveying pipe is circular, and the inner diameter of the reducing structure 109 is square. The reducing structure 109 is used to transition the material conveying pipe from circular to square along the material flow direction, ensuring that the material can enter the cavity 101 quickly and evenly.

[0035] In another embodiment, the moisture detection device 100 further includes an observation window 111. Exemplarily, the observation window 111 is disposed on the other side wall of the cavity 101, and is used to observe the target material within the cavity 101. The observation window 111 is used to observe the condition of the material, the degree of compaction of the material within the cavity 101, and the presence of porosity. If porosity is found, it will cause inaccurate measurements, allowing for timely investigation of the cause of the abnormality. In this embodiment, the observation window 111 can be made of a light-transmitting material, allowing real-time observation of the material's state within the cavity 101. With the visual feedback provided by the observation window 111, abnormal states can be identified during the detection process, triggering alarms, pausing the detection process, or activating the vibration device 106 to eliminate porosity and redistribute the material, thereby improving the accuracy and reliability of moisture detection data.

[0036] In this embodiment, the flow state of the material is controlled by controlling the action of the gate valve 104, transforming the dynamic material flow into a static state. This allows the moisture detection sensor 103 to perform measurements in a static environment, ensuring the material remains stationary and reducing the influence of environmental factors. These environmental factors include the flow state of the material and the presence of internal gaps due to varying particle sizes. The moisture detection sensor 103 measures the water content per unit volume of material. During flow, the internal gaps and density of the material change, causing fluctuations in the moisture content per unit volume and resulting in measurement errors. Furthermore, the moisture detection device 100 can be installed at the point where the material has been crushed, where negative pressure exists. The material is suspended in the pipe, unable to compact the sensor, leading to lower detection values. The moisture detection device 100 effectively solves the problem of material suspension under negative pressure, addressing the challenge of requiring material compaction for detection.

[0037] The moisture detection device 100, through the aforementioned transition from dynamic to static states, resolves errors caused by environmental factors, effectively avoiding their existence. By transmitting high-level signals, it ensures the accuracy and reliability of the detection data, guaranteeing that each measurement is performed at a high level, and that the transmitted value carries the high level information, ensuring the reliability of the transmitted detection value. The moisture detection device 100 avoids clogging by vibrating and shaking the material, mitigating the impact of varying particle sizes and reducing the probability of clogging. This improves the stability and reliability of the moisture detection device 100 and eliminates the need for data calibration during moisture data transmission.
