[0003] In prior art, the teaching and training of tunnel type moisture regaining machine mainly utilizes data explanation, and after the data is learned by trainee, practical operation is carried out on actual equipment under the guidance of instructor, to ensure that trainee can be familiar with equipment and deepen understanding.

[0004] However, safety factor needs to be considered in practical operation, and it is difficult to simulate complete actual production process, so that practical operation is very single, the real ability of trainee is difficult to be exercised and examined, and the overall training effect is poor. UTILITY MODEL CONTENT

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0039] This utility model embodiment discloses a tunnel-type rehumidifier teaching platform.

[0040] Reference Figure 1The tunnel-type rehumidifier teaching platform includes a control cabinet, a main pipeline 1, a simulation branch pipeline 3, a simulation control component, and a cleaning branch pipeline 4. The main pipeline 1 is located in the control cabinet and is used to guide compressed air or cleaning fluid. One end of the simulation branch pipeline 3 is connected to the main pipeline 1, and the other end is connected to the simulator 2 to guide compressed air into the simulator 2 for simulated operation. The simulation control component is located in the simulation branch pipeline 3 and regulates the compressed air within it. One end of the cleaning branch pipeline 4 is connected to the main pipeline 1, and the other end is connected to the simulator 2 to guide cleaning fluid into the simulator 2 for cleaning.

[0041] Specifically, the control cabinet is hollow inside, housing various electrical components such as feeders, motors, and general-purpose devices. These components work in conjunction with simulator 2, enabling simulator 2 to simulate the actual operation process of a tunnel-type rehumidifier and allowing for PLC programming. This allows the tunnel-type rehumidifier teaching platform to conduct electrical training and assessments, extend experiments, provide an electrical improvement testing environment, and simulate actual operating procedures. The specific electrical components can be designed according to actual simulation needs; this invention does not impose specific limitations in this regard.

[0042] A controller is installed inside the control cabinet. The main pipeline 1 can be connected to either an air compressor or a water pump, allowing compressed air or cleaning fluid to flow within it. When compressed air flows through the main pipeline 1, the trainee uses the controller to keep the cleaning branch 4 closed and open the simulation branch 3, allowing compressed air to enter the simulator 2. The simulation control component can detect the compressed air, and the trainee can adjust its temperature, flow rate, and pressure in real time based on the detection results, ensuring the compressed air meets the requirements of the simulated operation. After the simulation operation is completed, the simulation branch 3 is closed and the cleaning branch 4 is opened, allowing the cleaning fluid flowing through the main pipeline 1 to be directed into the simulator 2 for cleaning, thus simulating the cleaning operation. The cleaning fluid can be water or a solution containing a cleaning agent; this invention does not limit the choice.

[0043] By setting up a main pipeline 1, a simulation branch pipeline 3, and a cleaning branch pipeline 4 in the control cabinet, and using compressed air instead of steam for simulated operation, the compressed air is monitored by the simulation control component as it flows in the simulation branch pipeline 3. The compressed air is then adjusted based on the monitoring results to reflect the characteristics of steam in terms of temperature and other aspects. Simulator 2 then simulates various operations of the equipment. After the simulation is complete, simulator 2 can be cleaned via cleaning branch pipeline 4, thus simulating the cleaning process. This tunnel-type rehumidifier teaching platform can use compressed air to simulate the preheating, standby, production, interruption, material tailing, and cleaning states of the equipment. Simulator 2 operates according to the actual production process, with compressed air replacing steam, ensuring safety for experiments and teaching. This allows trainees to simulate the entire operation process in a safe environment, enabling them to practice each step of the operation based on the explained materials. This effectively enriches the operational procedures in the teaching process, allowing trainees to efficiently develop their skills and facilitating the setting of more challenging assessments, thereby effectively improving the overall training effect.

[0044] Optionally, the analog branch 3 has a return position, and the analog control components include a first pressure gauge 31, a first flow meter 32, a first branch 33, and a first switching valve 34. The first pressure gauge 31 and the first flow meter 32 are both located between the return position and the main branch 1, the first branch 33 is connected to the return position, and the first switching valve 34 is located in the first branch 33.

[0045] Specifically, the first pressure gauge 31 can detect the air pressure value of compressed air, and the first flow meter 32 can detect the flow rate of compressed air. The first pressure gauge 31, the first flow meter 32, and the first switching valve 34 can all communicate with the controller.

[0046] When compressed air enters simulated branch 3, it passes sequentially through the first pressure gauge 31 and the first flow meter 32. If the values ​​detected by the first pressure gauge 31 and the first flow meter 32 do not meet the simulation requirements, the trainee can control the first switching valve 34 to open the first branch 33, allowing the compressed air to flow out through it. Conversely, when the values ​​detected by the first pressure gauge 31 and the first flow meter 32 meet the simulation requirements, the first switching valve 34 is closed, shutting off the first branch 33, allowing the compressed air to enter simulator 2 along simulated branch 3. This allows trainees to practice and assess their operational procedures when gas quality does not meet requirements.

[0047] Optionally, the simulation control component also includes a second pressure gauge 35, a one-way valve 36, a third pressure gauge 37, and a second flow meter 38 disposed between the return position and the simulator 2.

[0048] Specifically, before flowing into simulator 2, the compressed gas passes sequentially through a second pressure gauge 35, a one-way valve 36, a third pressure gauge 37, and a second flow meter 38 to repeatedly detect the pressure and flow rate of the compressed gas, thereby ensuring that the connection points of each connection point in the simulated branch 3 are functioning correctly. This allows trainees to practice and assess their control over data during gas flow and their observation of various instruments.

[0049] Optionally, at least one first temperature transmitter 39 is provided between the second flow meter 38 and the simulator 2.

[0050] Specifically, multiple first temperature transmitters 39 can be distributed at intervals. In this embodiment, one first temperature transmitter 39 is set on the simulation branch 3, and another first temperature transmitter 39 can also be set at the connection between the simulator 2 and the simulation branch 3, so as to measure the temperature of the compressed gas multiple times, thereby determining the temperature change trend of the compressed gas. This can train and test the trainees' ability to respond to changes in the temperature of the compressed gas.

[0051] Optionally, the cleaning branch 4 is equipped with a second temperature transmitter 41.

[0052] Specifically, a second temperature transmitter 41 is installed near simulator 2 in cleaning branch 4 to monitor the temperature of the cleaning fluid in real time. This allows trainees to practice and assess their ability to control the temperature of the cleaning fluid.

[0053] Optionally, a cleaning switch valve 42 is provided between the second temperature transmitter 41 and the simulator 2.

[0054] Specifically, the cleaning switch valve 42 controls the on / off state of the cleaning branch 4, and the second temperature transmitter 41 and the cleaning switch valve 42 can communicate with the controller. When the trainee determines that the cleaning fluid temperature is suitable through the second temperature transmitter 41, he can control the cleaning switch valve 42 to open through the controller. This allows the trainee to practice and assess the relevant operations during the cleaning process.

[0055] Optionally, the tunnel-type rehumidifier teaching platform includes a second branch 5. The second branch 5 is connected to the cleaning branch 4 between the cleaning switch valve 42 and the temperature transmitter.

[0056] Specifically, the second diversion branch 5 allows the cleaning fluid to be diverted to other locations when it does not meet cleaning requirements, or to be diverted to other locations after cleaning is completed. The second diversion branch 5 can be controlled by a separate valve or directly by a water pump. In this embodiment, the second diversion branch 5 is equipped with a diversion switch valve 51, which is communicatively connected to the controller. This allows trainees to practice and assess their specific operational skills during the cleaning process.

[0057] Optionally, a second switching valve 6 is provided at the connection between the cleaning branch 4 and the main branch 1, and at the connection between the simulated branch 3 and the main branch 1.

[0058] Specifically, the second switching valve 6 can be two solenoid valves, respectively installed on the cleaning branch 4 and the simulation branch 3, to directly control the on / off connection between the cleaning branch 4 or the simulation branch 3 and the main pipeline 1. The second switching valve 6 can also be a three-way valve, which can also control the corresponding on / off connection. This allows trainees to practice and assess their opening and closing operations during the cleaning and simulation phases.

[0059] Optionally, the tunnel-type rehumidifier teaching platform also includes a return branch 7. The return branch 7 is connected to the main pipeline 1, the cleaning branch 4, and the simulation branch 3, respectively.

[0060] Specifically, the return branch 7 includes a main return line 71 and multiple return branch lines 72. The main return line 71 is connected to all the return branch lines, and a third switching valve 73, a fourth pressure gauge 74, and a third flow meter 75 are installed on the main return line 71. Each return branch line 72 is equipped with a control valve 721. Among them, the first switching valve 34, the cleaning switching valve 42, and the diversion switching valve 51 are each connected to one return branch line 72. A cleaning return switching valve 43 is also installed between the second switching valve 6 and the cleaning switching valve 42 in the cleaning branch line 4. A simulated return switching valve 30 is installed between the one-way valve 36 and the third pressure gauge 37 in the simulated branch line 3. The cleaning return switching valve 43 and the simulated return switching valve 30 are also connected to one return branch line 72.

[0061] Trainees can control the on / off state of the return branch 7 via the third switching valve 73, and can monitor the return medium in real time to ensure it meets requirements via the fourth pressure gauge 74 and the third flow meter 75. The multiple return branches 72 allow compressed air and cleaning fluid to be returned and recovered separately, reducing the amount of shared piping between media and minimizing mutual interference. This allows trainees to practice and assess their operational skills during the media return process.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
