[0017] Embodiment

[0018] As Figure 1 - Figure 2 shown, the present utility model provides an exhaust device for improving the capacity of the main filter.

[0019] It includes a main filter 1 and an exhaust device 2. The exhaust device 2 is arranged at the upper end of the main filter 1. The exhaust device 2 includes an air outlet pipe 3 and an adjusting mechanism. The lower end of the air outlet pipe 3 is communicated with the main filter 1. The upper end of the air outlet pipe 3 is provided with a cover plate 4. The side wall of the air outlet pipe 3 is communicated with an exhaust pipe 5. The gas in the main filter 1 is transported to the exhaust pipe 5 through the air outlet pipe 3 and discharged. The adjusting mechanism is arranged on the air outlet pipe 3 and is used to adjust the exhaust volume of the air outlet pipe 3. The adjusting mechanism includes a motor 6, a screw rod 7, and an adjusting plate. The motor 6 is arranged at the upper end of the cover plate 4. The lower end of the screw rod 7 penetrates through the lower end of the cover plate 4 and extends into the air outlet pipe 3. The adjusting plate is connected to the screw rod 7 inside the air outlet pipe 3. The output shaft of the motor 6 drives the screw rod 7 to rotate, thereby driving the adjusting plate to move up and down along the side wall of the screw rod 7, so as to adjust the communication area between the air outlet pipe 3 and the exhaust pipe 5. The motor 6 is set as a stepper motor 6, which can accurately control the moving position and speed of the adjusting plate.

[0020] A gasket is arranged between the cover plate 4 and the air outlet pipe 3 to ensure the airtightness of the air outlet pipe 3 and prevent gas leakage.

[0021] The cross-section of the adjusting plate is set as a circular structure, or the cross-section of the adjusting plate is set as a rectangular structure.

[0022] It also includes a sensor and a control unit. The sensor is arranged inside the air outlet pipe 3 and is used to detect gas flow and pressure. The control unit controls the operation of the motor 6 according to the detection data of the sensor to realize automatic adjustment of the exhaust volume. The control unit adopts a PLC system. Specifically:

[0023] Sensor part:

[0024] A gas flow sensor and a pressure sensor are installed inside the air outlet pipe 3. These sensors can monitor the gas flow and pressure in real time. The flow sensor can adopt types such as thermal type, ultrasonic type, or differential pressure type for accurately measuring the gas flow, and the pressure sensor is used to measure the gas pressure inside the air outlet pipe 3.

[0025] Data transmission:

[0026] The sensor transmits the measured flow and pressure data to the control unit in real time through cables or wirelessly. The data transmission can be continuous or carried out at set time intervals.

[0027] Control unit part:

[0028] Receiving data:

[0029] The control unit receives real-time data from the sensors and processes and analyzes this data.

[0030] Setting thresholds and algorithms:

[0031] An ideal range or threshold for gas flow and pressure is preset in the control unit.

[0032] One or more algorithms run inside the control unit to determine whether the current gas state needs adjustment based on the received sensor data and the preset thresholds.

[0033] Issuing instructions:

[0034] When the control unit determines that the gas flow or pressure exceeds the preset range, it calculates the adjustment amount according to the algorithm and issues an instruction to the motor 6. The instruction can be to change the rotation speed or direction of the motor 6, so as to drive the adjustment plate to move up and down through the screw rod 7, and adjust the connection area between the air outlet pipe 3 and the exhaust pipe 5.

[0035] Feedback mechanism:

[0036] After the adjustment, the control unit continues to receive the sensor data to verify the adjustment effect. If the adjusted data is still outside the preset range, the control unit will make further adjustments until the ideal state is reached.

[0037] Example:

[0038] Suppose the gas flow sensor in the air outlet pipe 3 detects that the flow rate is too low, lower than the preset minimum threshold. After receiving this data, the control unit will determine that it is necessary to increase the connection area between the air outlet pipe 3 and the exhaust pipe 5 to increase the gas flow rate. Therefore, the control unit issues an instruction to the motor 6 to rotate forward by a certain angle, drives the adjustment plate to move upward through the screw rod 7, thereby increasing the connection area. After the motor 6 executes the instruction, the flow sensor will detect the change in the flow rate and feedback the new data to the control unit to confirm whether the adjustment has achieved the expected effect.

[0039] In this way, through the collaborative work of the sensor and the control unit, the exhaust device 2 can automatically adjust the exhaust volume to adapt to different gas treatment requirements.

[0040] The exhaust device 2 of this application controls the gas flow rate by dynamically adjusting the connection area between the air outlet pipe 3 and the exhaust pipe 5, which is mainly achieved through an adjustment mechanism. This mechanism includes a motor 6, a screw rod 7 and an adjustment plate. The motor 6 drives the screw rod 7 to rotate, thereby driving the adjustment plate to move up and down in the air outlet pipe 3. By changing the position of the adjustment plate, the opening size between the air outlet pipe 3 and the exhaust pipe 5 can be adjusted, and thus the gas emission amount can be controlled.

[0041] In addition, sensors and a control unit are integrated in the device to continuously monitor the gas flow rate and pressure in real time, and automatically adjust the position of the regulating plate according to this data to achieve the optimal gas treatment effect.

[0042] The use process of this utility model includes the following steps:

[0043] Initialization: After the system is started, components such as the motor 6, sensors, and control unit perform self-checks and initialization.

[0044] Gas flow rate and pressure monitoring: The sensors continuously monitor the gas flow rate and pressure in the outlet pipe 3 and transmit this data to the control unit in real time.

[0045] Data processing and judgment: The control unit receives the data from the sensors and judges whether the current gas flow rate and pressure are in the optimal state according to a preset algorithm. If not, the control unit will calculate the gas emission volume that needs to be adjusted.

[0046] Adjusting the exhaust volume: According to the calculation result of the control unit, the motor 6 is started and drives the screw rod 7 to rotate. The rotation of the screw rod 7 drives the regulating plate to move up and down in the outlet pipe 3, thereby changing the communication area between the outlet pipe 3 and the exhaust pipe 5 to achieve the purpose of adjusting the gas emission volume.

[0047] Real-time feedback and adjustment: During the adjustment process, the sensors continue to monitor the gas flow rate and pressure and provide real-time feedback to the control unit. The control unit continuously adjusts the position of the regulating plate according to the feedback data until the optimal gas treatment effect is achieved.

[0048] Stable operation and monitoring: Once the system reaches a stable state, the control unit will continue to monitor the sensor data and make fine adjustments as needed to ensure that the system always remains in the optimal working state.

[0049] Through the above steps, the exhaust device 2 of this application can perform dynamic adjustment according to the actual gas flow rate and pressure requirements, improve the gas treatment efficiency, and at the same time reduce energy consumption and waste.

[0050] By dynamically adjusting the exhaust volume of the exhaust device 2, this utility model can optimize the gas flow efficiency, which helps to reduce the residence time of the gas in the filter, thereby improving the treatment efficiency of the entire gas treatment system. The optimized exhaust system can reduce energy consumption. By reducing unnecessary exhaust resistance, the system runs more efficiently. This can not only reduce the operating cost of the equipment but also conform to the current environmental protection trend of energy conservation and emission reduction.

[0051] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
