Description

Technical Field

[0001] This utility model relates to the field of fumigation technology, and in particular to a device for adjusting the circulation path of fumigation agents. Background Technology

[0002] In fumigation operations, the stability of the gas circulation path directly affects the fumigation effect. As a key component of the gas circulation system, the cleanliness of the filter plate directly affects the smoothness of the gas path. When the filter plate experiences a decrease in local permeability due to impurities, it will disrupt the original equilibrium of the gas circulation, causing problems such as path deviation and uneven flow rate. This, in turn, affects the distribution efficiency and range of action of the fumigation medium. Therefore, the dynamic adjustment of the fumigation gas circulation path must simultaneously take into account the basic support of filter plate cleanliness for path stability, ensuring the high efficiency of fumigation gas circulation.

Specifically, the base 1 provides stable support for the water tank 2, which is used to provide water for cleaning. The water tank 2 also fixes the water pump 3 to ensure its stability during operation. The water pump 3 is used to pump water through the first water pipe 4 into the second water pipe 5. The spray box 6 has a hollow internal structure and a nozzle on its outer wall. After the water enters the spray box 6 through the second water pipe 5, it cleans the filter plate 9 through the nozzle. The air box 8 provides space for filtering the gas and fixes the filter plate 9. The filter plate 9 filters the gas entering the air box 8 to ensure the purity of the gas. The light bar 11 limits the movement of the connecting plate 7 to ensure that the connecting plate 7 does not shift during movement.

[0021] Reference Figure 1 , Figure 2 and Figure 3 The lifting assembly includes a motor 12, the lower surface of which is fixedly connected to the upper surface of the U-shaped frame 10. The output end of the motor 12 is rotatably connected to the inside of the U-shaped frame 10 and is fixedly connected to a threaded rod 13. The outer wall of the threaded rod 13 is rotatably connected to the inside of the U-shaped frame 10, and the outer wall of the threaded rod 13 is threadedly connected to the inside of the connecting plate 7. Specifically, the U-shaped frame 10 can fix the motor 12 to ensure the stability of the motor 12 during operation and prevent the motor 12 from shaking during driving. The output end of the motor 12 rotates, thereby driving the threaded rod 13 to rotate. The threaded rod 13 is used to convert the rotational motion of the motor 12 into the vertical linear motion of the connecting plate 7 to raise and lower the spray box 6.

[0022] Reference Figure 1 , Figure 2 and Figure 4 A fan 14 is fixedly connected to the upper surface of the base 1.

The outer wall of tube 8 is provided with a first slot 19; the outer wall of the second cylindrical tube 17 is fixedly connected to a limiting box 20, the inside of the limiting box 20 is slidably connected to a first sliding post 21, the first sliding post 21 is slidably connected to the inner wall of the second cylindrical tube 17, and the first sliding post 21 is slidably connected to the inner wall of the first slot 19; the outer wall of the first sliding post 21 is fixedly connected to a sliding plate 22, the outer wall of the sliding plate 22 is slidably connected to the inner wall of the limiting box 20, one end of the first spring 23 is fixedly connected to the upper surface of the sliding plate 22, and the other end of the first spring 23 is fixedly connected to the inner wall of the limiting box 20; Specifically, the base 1 secures the fan 14, ensuring its stability during operation and preventing deviation during drive. The fan 14 draws gas through the inlet pipe 15 into the second outlet pipe 24. The base 1 supports the first cylindrical pipe 16, which carries the gas from the second outlet pipe 24 into the second cylindrical pipe 17. The second cylindrical pipe 17 then transports the gas from the first cylindrical pipe 16 to the first outlet pipe 18, where it is discharged for fumigation. The first cylindrical pipe 16 can also be used to transport the gas from the first outlet pipe 18. Excess gas inside is recovered and re-enters the first air outlet duct 18 through the second cylindrical tube 17 for fumigation to achieve a circulation effect. The second cylindrical tube 17 provides support for the limiting box 20, which provides sliding space for the first sliding column 21. The first air outlet duct 18 can be limited and fixed by the cooperation of the first sliding column 21 and the first slot 19. One end of the first spring 23 is fixedly connected to the upper surface of the slide plate 22, and the other end of the first spring 23 is fixedly connected to the inside of the limiting box 20 to ensure that the first spring 23 maintains a certain contraction force. After adjustment, the first spring 23 automatically resets. Example

[0023] Reference Figure 5 A second fixing block 25 is fixedly connected to the upper surface of the second cylindrical tube 17. A first fixing block 26 is fixedly connected to the upper surface of the second fixing block 25. A limit post 27 is rotatably connected inside the first fixing block 26. A rotating plate 28 is fixedly connected to the outer wall of the limit post 27. A second sliding post 29 is slidably connected inside the rotating plate 28. The bottom end of the second sliding post 29 is fixedly connected to the upper surface of the second fixing block 25. One end of the second spring 30 is fixedly connected to the lower surface of the rotating plate 28. The other end of the second spring 30 is fixedly connected to the upper surface of the second fixing block 25. A third sliding post 31 is fixedly connected to the outer wall of the rotating plate 28. The outer wall of the third sliding post 31 is slidably connected to the inside of the second cylindrical tube 17. The outer wall of the third sliding post 31 is slidably connected to the inner wall of the first slot 19. Specifically, the second fixing block 25 provides fixation and support for the first fixing block 26. The first fixing block 26 is used to limit the movement of the limiting post 27, ensuring that the limiting post 27 always moves in a circular motion during rotation. The limiting post 27 can fix the rotating plate 28, ensuring that the rotating plate 28 will not wobble during rotation. The third sliding post 31 and the first slot 19 cooperate to fix and limit the first air outlet pipe 18. The second sliding post 29 is used to limit the rotation plate 28 to ensure the stability of the rotation plate 28 during rotation. One end of the second spring 30 is fixedly connected to the lower surface of the rotating plate 28, and the other end of the second spring 30 is fixedly connected to the upper surface of the second fixing block 25, which can ensure that the second spring 30 maintains a certain contraction force. The second spring 30 is used to automatically reset after the adjustment of the first air outlet pipe 18 is completed.

[0024] Working principle: When the filter plate 9 needs cleaning, the motor 12 is started. The rotation of the output end of the motor 12 drives the threaded rod 13 to rotate, so that the threaded rod 13 rotates inside the U-shaped frame 10 during the rotation. In turn, the threaded rod 13 drives the connecting plate 7 to move. During this process, the movement of the connecting plate 7 drives the spray box 6 to move. When the spray box 6 reaches the inside of the air box 8, the water pump 3 is started to make water flow through the first water pipe 4 into the second water pipe 5. The water then flows through the second water pipe 5 into the spray box 6 and is sprayed out through the nozzle to achieve the effect of cleaning the filter plate 9. This is conducive to the automated cleaning of the filter plate 9. By controlling the position of the spray box 6, the cleaning coverage is more comprehensive.

[0025] When the first air outlet duct 18 needs adjustment, pull the first sliding column 21 upwards. This causes the first sliding column 21 to slide along the inner wall of the first slot 19 during its movement. Simultaneously, it also causes the first sliding column 21 to slide along the inner wall of the second cylindrical tube 17. During this process, the first sliding column 21 moves and slides inside the limiting box 20. The movement of the first sliding column 21 drives the sliding plate 22 to move, causing the sliding plate 22 to slide inside the limiting box 20. At this point, the first air outlet duct 18 can be adjusted. After adjustment, release the first sliding column 21. The return of the first spring 23 causes the sliding plate 22 to move, causing it to slide inside the limiting box. Inside the limit box 20, the slide plate 22 moves, causing the first slide column 21 to move. This causes the first slide column 21 to slide on the inner wall of the first slot 19 and the inner wall of the second cylindrical tube 17. During this process, the first slide column 21 moves and slides inside the limit box 20, so that the first air outlet 18 is automatically reset by the first spring 23 after adjustment. This achieves the effect of adjusting the first air outlet 18, which is beneficial to the flexible adjustment of the first air outlet 18 by pulling and resetting the first slide column 21 when adjustment is needed, so that the circulation path can be changed appropriately according to actual needs.

[0026] When the first air outlet duct 18 needs adjustment, press down on the rotating plate 28, causing it to rotate and slide on the outer wall of the second sliding column 29. This causes the rotating plate 28 to drive the third sliding column 31 to rotate, sliding on the inner wall of the first slot 19 during rotation. Simultaneously, the third sliding column 31 also slides on the inner wall of the second cylindrical tube 17 during rotation. During this process, the rotating plate 28 rotates, causing the limiting column 27 to rotate inside the first fixed block 26. At this point, the first air outlet duct 18 can be adjusted. After adjustment, release the rotating plate 28. The second spring 30's reset action causes the rotating plate 28 to rotate, allowing it to slide on the outer wall of the second sliding column 29. The rotating plate 28 drives the third sliding column 31 to rotate, causing the third sliding column 31 to slide on the inner wall of the first slot 19 during rotation. At the same time, the third sliding column 31 also slides on the inner wall of the second cylindrical tube 17 during rotation. During this process, the rotating plate 28 drives the limiting column 27 to rotate, causing the limiting column 27 to rotate inside the first fixed block 26. After the first air outlet pipe 18 is adjusted, it is automatically reset by the second spring 30, thereby achieving the effect of adjusting the first air outlet pipe 18. This is beneficial for the first air outlet pipe 18 to be quickly adjusted by the rotation of the rotating plate 28 and the reset of the second spring 30 after adjustment, reducing the adjustment time required.
