[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a cold storage ventilation and air exchange device, including a ventilation duct 1 and a treatment box 2. Second mounting frames 15 are installed at both ends of the treatment box 2, and a first mounting frame 14 is installed at one end of the ventilation duct 1. Multiple mounting holes 16 are provided inside both the first mounting frame 14 and the second mounting frame 15. The first mounting frame 14 and the second mounting frame 15 are fixed together with screws, facilitating the fixing and disassembly of the ventilation duct 1 and the treatment box 2. A filter plate 3 is rotatably connected inside the treatment box 2, and a filter screen is installed inside the filter plate 3 to filter and intercept dust and other substances in the air. Inside the treatment chamber 2, and rotatably connected to one side of the filter plate 3, is a baffle 4. Two self-locking motors 10 are installed on one side of the treatment chamber 2. The output ends of the two self-locking motors 10 are fixedly connected to the filter plate 3 and the baffle 4 respectively, providing power for the rotation of the filter plate 3 and the baffle 4. This facilitates adjustment of the angle of the baffle 4 and the gap between the baffle 4 and the treatment chamber 2, controlling the airflow. The edges of both the filter plate 3 and the baffle 4 are flush with the inner wall of the treatment chamber 2. The edges of both the filter plate 3 and the baffle 4 are arc-shaped, which helps prevent the treatment chamber 2 from obstructing the rotation of the filter plate 3 and the baffle 4. Inside the treatment chamber 2, and between the filter plate 3 and the baffle 4, is installed... The three-way connector 5 has nozzles 6 fixedly connected to both ends. A water pump 7 is installed on the top of the treatment tank 2. A guide pipe 8 is fixedly connected to the output end of the water pump 7, and one end of the guide pipe 8 is fixedly connected to the three-way connector 5. An inlet pipe 9 is fixedly connected to the input end of the water pump 7, and one end of the inlet pipe 9 is connected to the water supply equipment. When the water pump 7 is running, water is guided through the inlet pipe 9 and the guide pipe 8 to the three-way connector 5, and then sprayed onto the filter plate 3 and the baffle 4 by the two nozzles 6 respectively. With the rotation of the filter plate 3 and the baffle 4, it is easy to rinse the filter plate 3 and the baffle 4, replacing manual cleaning of the filter plate 3 and the baffle 4. The inner wall of the treatment tank 2 is provided with a water tank 11. Multiple drain holes 12 are located inside the treatment tank 2 and at the top of the water tank 11, between the filter plate 3 and the baffle 4. A drain pipe 13 is fixedly connected to the bottom of the water tank 11, allowing wastewater to flow into the water tank 11 through the drain holes 12 and then be discharged through the drain pipe 13. Water-blocking strips 17 are installed inside the treatment tank 2 on one side of the filter plate 3 and the baffle 4 to prevent wastewater from overflowing into the ventilation duct 1. A solenoid valve is installed on one side of the drain pipe 13 to control its opening and closing. The control switches for the self-locking motor 10 and the solenoid valve, among other electrical components, are integrated and located outside the treatment tank 2.

[0022] In summary, when using this cold storage ventilation device, the two ends of the processing box 2 are aligned with the two adjacent ventilation ducts 1, so that the first mounting frame 14 at one end of each of the two ventilation ducts 1 is fitted with the second mounting frames 15 at both ends of the processing box 2. Screws are passed through the mounting holes 16 in the first mounting frames 14 and the second mounting frames 15 for fixing, thus installing the ventilation ducts 1 and the processing box 2 together. The airflow passes through the filter plate 3 and flows through the gap between the baffle 4 and the processing box 2. When it is necessary to adjust the flow rate, one of the self-locking motors 10 drives the baffle 4 to rotate, adjusting the angle of the baffle 4 and the size of the gap between it and the processing box 2. When it is necessary to clean the filter plate 3 and the baffle 4, the processing box... Inside component 2, between filter plate 3 and baffle 4, are two nozzles 6. The two nozzles 6 face filter plate 3 and baffle 4 respectively. Therefore, when water pump 7 is running, water can be guided through inlet pipe 9 and guide pipe 8 to T-joint 5, and then sprayed onto filter plate 3 and baffle 4 by the two nozzles 6. Two self-locking motors 10 simultaneously drive filter plate 3 and baffle 4 to rotate, rinsing them thoroughly. At the same time, water flows out into water tank 11 through multiple drain holes 12. The drain pipe 13 is opened by solenoid valve to discharge sewage in water tank 11 into sewage pipe. After the operation is completed, the solenoid valve closes drain pipe 13, nozzles 6 stop spraying water, and the two self-locking motors 10 drive filter plate 3 and baffle 4 to reset.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
