Description

Technical Field

[0001] This utility model relates to the field of ventilation control technology, and in particular to a diversion ventilation control device. Background Technology

[0002] Split-flow ventilation is a ventilation method that distributes air to different areas or spaces to ensure airflow and temperature control in each area. This method is commonly used in environments requiring regulated air quality and temperature distribution, such as industrial production, buildings, and workshops. Control devices are used to precisely regulate airflow and direction to achieve more efficient airflow and ensure that the ventilation needs of different areas are met. The beneficial effects of control devices include improved ventilation efficiency, energy savings, ensuring personnel safety and health, and optimizing environmental comfort. By rationally controlling airflow, energy waste and over-ventilation can be avoided, while ensuring a reasonable distribution of air quality and temperature.

[0003] Existing diversion ventilation control devices regulate air distribution and flow by sensing parameters such as airflow, temperature, humidity, and pressure in the environment. Their working principle typically relies on the coordination of sensors, controllers, and actuators. Sensors monitor real-time environmental data, the controller calculates and judges based on set target values ​​and sensor feedback, and then adjusts the opening and closing of fans, regulating valves, or ducts via actuators to achieve precise airflow and temperature control. In this way, diversion ventilation control devices can intelligently allocate and adjust ventilation volume according to the needs of different areas, ensuring efficient operation of the ventilation system and optimizing energy use and environmental comfort.

[0004] In existing technologies, some diversion ventilation control devices use filters to remove particulate matter and pollutants from the air. However, due to the lack of automatic cleaning mechanisms or regular maintenance, these filters gradually become clogged with contaminants over time, leading to a gradual weakening of their filtration effect. This not only reduces the air purification capacity of the ventilation device but also causes a decrease in ventilation efficiency, increases energy consumption, and shortens the device's lifespan. Therefore, filters lacking cleaning functions affect the long-term operating performance and maintenance costs of ventilation devices. To address these issues, a diversion ventilation control device is proposed. Utility Model Content

[0018] 1. When cleaning of the filter shaft inside the diversion pipe is required, the push rod located at the rear of the diversion pipe is activated, pushing the scraper to slide inside the filter shaft. This causes the dirt adsorbed on the inner wall of the filter shaft to be scraped away by the scraper. Then, the adjusting push rod located inside the mounting block is activated, pushing the guide sliding block to slide, which in turn drives the front locking block and the auxiliary locking block to rotate. During the rotation of the front locking block and the auxiliary locking block, the upper sealing leaf and the lower sealing leaf move closer to each other and fit together, thereby releasing the restriction on the drain pipe. This allows the dirty air to flow out of the interior of the diversion pipe through the drain pipe, thus achieving self-cleaning of the filter shaft, reducing subsequent maintenance costs, and improving the efficiency of air discharge.

The function of the air intake block 2 is to guide air into the system and optimize airflow in conjunction with subsequent components such as the fan bracket 3. The air intake block 2 is fixedly connected to the front side of the diversion pipe 1. The fan bracket 3 is fixedly connected inside the air intake block 2 and supports the fan motor. The fan motor drives multiple fan blades 4 to rotate, drawing in air and pushing it towards the diversion pipe 1, thereby increasing the ventilation efficiency of the system. The fan frame 3 is equipped with a fan motor inside, and multiple fan blades 4 are fixedly connected to the drive end of the fan motor. The fan blades 4 accelerate the airflow, increase the intake volume, and ensure the stability of the airflow. An air inlet is opened on the rear side of the air inlet block 2, which corresponds to the diversion pipe 1.

[0032] The air purification mechanism includes a spray block 12, which is fixedly connected to the front of the drain pipe 11. Its main function is to help remove pollutants from the air by spraying water. The spray block 12 is fixedly connected to the front of the drain pipe 11, and a water guide pipe 14 is fixedly connected to the top of the drain pipe 11. A water storage tank 16 is fixedly connected to the other end of the water guide pipe 14 to store water. A water pump 15 is fixedly connected to the outside of the water guide pipe 14. The water pump 15 ensures that water can flow smoothly into the spray block 12 by providing water pressure. To achieve the purpose of cleaning the sewage pipe 11, a water guide block 17 is fixedly connected to the front side of the water storage tank 16, which guides the water flow into the water storage tank 16 to ensure the continuity and stability of the spray cleaning process. A return air port 13 is fixedly connected to the front side of the spray block 12, which is used for the discharge or recovery of gas to ensure the air circulation of the ventilation system. A water storage pool is opened inside the water storage tank 16, and a water inlet is opened on the front side of the water storage tank 16, which corresponds to the water guide block 17.

[0033] Working principle: The fan motor located inside the fan frame 3 starts, and drives the fan blades 4 fixed to the drive end of the fan motor to rotate, thereby drawing external air into the air intake block 2. Then, the air flows into the split pipe 1 through the air intake hole on the rear side of the air intake block 2. The air entering the split pipe 1 is then filtered by the filter shaft 6 inside the split pipe 1. The filtered air is then guided to the next step and discharged through the air guide pipe 5.

[0034] When cleaning of the filter shaft 6 is required, the push rod 9, fixed to the rear side of the diversion pipe 1 by the push rod bracket 8, is activated. The push rod 9 pushes the scraper 7 to scrape inside the filter shaft 6, causing the dirt adsorbed inside the filter holes of the filter shaft 6 to float. Then, it is driven by the air entering the diversion pipe 1, and then the adjusting push rod 19, fixed inside the mounting block 18, is activated, thereby pushing the guide sliding block 20 to slide. With the help of the guide groove inside the guide sliding block 20, the front locking block 23 and the auxiliary locking block 24 are pushed to slide. Then, the front locking block 23 and the auxiliary locking block 24 drive the rotating shaft 22 to rotate. During this process, the front locking block 23 and the auxiliary locking block 24 interlock to ensure the consistency of the rotation speed of the front locking block 23 and the auxiliary locking block 24 during the rotation process. Then, during the rotation of the rotating shaft 22, the upper sealing leaf 25 and the lower sealing leaf 26 fixed outside the rotating shaft 22 are driven to stick together to release the restriction on the drain pipe 11, so that the air with dirt flows through the drain pipe 11 to the spray block 12.

[0035] Then, the water pump 15 located outside the water pipe 14 is started, guiding the water inside the water storage tank 16 through the water pipe 14 to the inside of the spray block 12, so as to spray the polluted air entering the spray block 12, reducing the pollutant content in the air. The sprayed air then returns to the room through the air return port 13. During this process, spray water can be added to the inside of the water storage tank 16 through the water pipe 17.
