[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figures 1-6 As shown, this utility model provides a technical solution:

[0023] The system includes a ventilation pipe 1 with a groove on it. A filter frame 2 is movably mounted on the groove. A fixing component is installed on one side of the ventilation pipe 1. A sealing frame 3 is fixedly connected to one end of the ventilation pipe 1. An opening and closing component is installed on the sealing frame 3. A pair of support rods 4 are fixedly connected to the bottom of the sealing frame 3. One end of each support rod 4 is fixedly connected to the ventilation pipe 1. A ventilation fan 5 is fixedly connected to the inner wall of the ventilation pipe 1. A connecting flange 22 is installed at the bottom of the ventilation pipe 1. The bottom of the pipe 1 is connected to the ventilation port of the steel silo through the connecting flange 22. When the opening and closing component and the sealing frame 3 are closed, humid air is effectively prevented from entering the steel silo to prevent the material from getting damp. When ventilating, the opening and closing component is opened, the ventilation fan 5 is activated, and outside air is sent into the steel silo through the ventilation pipe 1. The fixing component can quickly fix and loosen the filter frame 3.

[0024] The fixing component includes a housing 6, which is fixedly connected to one side of the vent pipe 1. A limiting rod 7 is fixedly connected to the top of the housing 6. A spring 8 is sleeved on the outer periphery of the limiting rod 7. A fixing rod 9 is slidably connected to the inner wall of the housing 6. A sliding hole is opened on the fixing rod 9. A connecting handle 10 is fixedly connected to the outer periphery of the fixing rod 9. A through groove is opened on one side of the housing 6. The spring 8 is always in a compressed state. The sliding hole on the fixing rod 9 is adapted to the limiting rod 7. Pulling the handle 10 upward causes the fixing rod 9 to slide upward through the sliding hole on the outer periphery of the limiting rod 7, and the spring 8 is further compressed.

[0025] A filter screen 11 is provided on the filter frame 2. A fixing hole is opened on the top of the filter frame 2. A handle 12 is fixedly connected to one side of the filter frame 2. The filter screen 11 is used to filter impurities in the air. The bottom of the fixing rod 9 can be fixed in the groove on the air vent 1 through the fixing hole. After the fixing rod 9 releases the filter frame 2, the filter frame 2 can be taken out by pulling the handle 12.

[0026] The opening and closing assembly includes a servo motor 13 and a pair of connecting plates 14. The servo motor 13 is fixedly connected to one side of the sealing frame 3. Each connecting plate 14 is fixedly connected to the inner wall of the sealing frame 3. The output end of the servo motor 13 passes through the sealing frame 3 and is rotatably connected to it. A rotating rod 15 is fixedly connected to the output end of the servo motor 13. A connecting shaft is fixedly connected to one side of the rotating rod 15. A rotating rod 16 is rotatably connected to the connecting shaft. A push rod 17 is rotatably connected to one end of the rotating rod 16. Connecting blocks 18 are fixedly connected to both ends of the push rod 17. An opening and closing door 19 is fixedly connected to one end of the connecting block 18. A sliding rod 20 and a sliding rod 21 are fixedly connected to the side of the connecting block 18 away from the push rod 17, respectively. A through groove is provided on each connecting plate 14. The servo motor 13 is started, and the output end of the servo motor 13 drives the rotating rod 15 to rotate. One end of the rotating rod 16 moves with the rotating rod 15, and the other end of the rotating rod 16 pushes the push rod 17 to move. The push rod 17 drives the connecting block 18 to move together, so that the sliding rod 20 and the sliding rod 21 first move along the straight area of ​​the through groove on the connecting plate 14. At this time, the opening and closing door 19 is pushed out of the sealing frame 3. When the sliding rod 20 moves to the arc part of the through groove, the opening and closing door 19 begins to rotate. When the sliding rod 20 moves to the other end of the through groove, the sliding rod 21 is in the arc part of the through groove. The center line connecting the sliding rod 20 and the sliding rod 21 remains vertical. At this time, the opening and closing door 19 rotates to the horizontal state.

[0027] A notch is provided on one side of the sealing frame 3. The opening and closing door 19 is adapted to the notch. A sealing strip is provided inside the notch to effectively prevent humid air from entering the steel silo and prevent the material from getting damp.

[0028] The working principle of this utility model is as follows:

[0029] The opening and closing door 19 is adapted to the recessed groove on one side of the sealing frame 3. A sealing strip is installed inside the recessed groove to effectively prevent humid air from entering the steel silo and prevent the material from getting damp. When ventilation is needed, the servo motor 13 is started first. The output end of the servo motor 13 drives the rotating rod 15 to rotate. One end of the rotating rod 16 moves with the rotating rod 15, and the other end of the rotating rod 16 pushes the push rod 17 to move. The push rod 17 drives the connecting block 18 to move together, so that the sliding rod 20 and the sliding rod 21 first move along the connecting plate. The sliding door 19 moves out of the sealing frame 3 when the sliding rod 20 moves to the arc part of the sliding groove. When the sliding rod 20 moves to the other end of the sliding groove, the sliding rod 21 is in the arc part of the sliding groove. The center line connecting the sliding rod 20 and the sliding rod 21 remains vertical. At this time, the opening and closing door 19 rotates to the horizontal state, and the ventilation fan 5 is started to send outside air into the steel silo through the ventilation pipe 1.

[0030] The spring 8 is always in a compressed state, which can push the bottom of the fixing rod 9 through the fixing hole to fix the filter frame 2 to the air vent 1. When disassembling, first pull the handle 10 upward, the spring 8 is further compressed, the handle 10 drives the fixing rod 9 to slide upward on the outer periphery of the limit rod 7, so that the fixing rod 9 moves away from the fixing hole, the filter frame 2 is released, and then the filter frame 2 is taken out by pulling the handle 12.

[0031] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
