[0031] Example 2: In this example, when manual ash unloading is required, the material in the ash hopper can be quickly transported to the ash unloading channel 1, improving emergency handling efficiency. Specifically, as follows... Figure 2 and Figure 5 As shown, a first auxiliary box 9 is connected to the side of the manual slide gate valve 2. A first slide plate 10 is installed inside the manual slide gate valve 2. The first slide plate 10 is connected through the first auxiliary box 9 near the side wall of the manual slide gate valve 2. A screw 11 is connected through the first auxiliary box 9. One end of the screw 11 is connected to a rotating component 12, and the other end of the screw 11 is connected to the side of the first slide plate 10. A second auxiliary box 14 is connected to the side of the pneumatic slide gate valve 3. A second slide plate 13 is installed inside the pneumatic slide gate valve 3. The second slide plate 13 is connected through the second auxiliary box 14 near the side wall of the pneumatic slide gate valve 3. A telescopic cylinder 15 is provided on the side of the pneumatic slide gate valve 3. The output end of the telescopic cylinder 15 is connected to the side of the second slide plate 13.

The internal design allows for convenient downward conveying of ash from the ash hopper via the manual slide gate valve 2. Therefore, when manual ash unloading is required, the material in the ash hopper can be quickly conveyed to the ash unloading channel 1, improving emergency handling efficiency. The telescopic cylinder 15 moves the second slide gate 13 from inside the pneumatic slide gate valve 3 to inside the second auxiliary box 14, allowing the accumulated ash conveyed downward by the manual slide gate valve 2 to be conveyed through the pneumatic slide gate valve 3 to the lower ash unloading channel 1.

[0032] Example 3: In this example, the overall ash removal efficiency is improved and the maintenance workload and cost are reduced by coordinating vibration with nozzle 18. Specifically, as follows: Figures 1-4 , Figure 7 and Figure 8As shown, an auxiliary component is provided on the ash discharge channel 1. The auxiliary component includes an air conveying component 16 installed on the ash discharge channel 1. The output end of the air conveying component 16 is connected to a nozzle 18 through a conveying pipe 17. The nozzle 18 is located inside the ash discharge channel 1 and the ash hopper, and the nozzle 18 is inclined downwards. A vibration component is provided on the ash discharge channel 1. The vibration component includes a drive component 19 installed on the ash discharge channel 1. The output end of the drive component 19 is connected to a half gear 20. The side end of the half gear 20 is meshed with a full gear 21. The full gear 21 contains... The unit is connected to an impact plate 24 via a rotating shaft 22. The impact plate 24 is located on the side wall of the ash discharge channel 1. A torsion spring 23 is sleeved on the outside of the rotating shaft 22. When the air supply component 16 is opened, the air supply component 16 transports gas through the conveying pipe 17 and sprays it out through the nozzle 18. The nozzle 18, which is set inside the ash discharge channel 1 and the ash hopper, is inclined downwards. Therefore, it can effectively prevent material from adhering and accumulating on the inner wall of the ash discharge channel 1 and the ash hopper by utilizing the impact force of the gas, keeping the ash discharge channel 1 and the ash hopper clean and unobstructed, and reducing the risk of material blockage. This reduces downtime for maintenance. When the lower electric valve 7 on the ash hopper detects that the ash in the ash hopper is empty, it sends a signal. At this time, the conveying pipe 17 of the nozzle 18 connected inside the ash hopper can be closed, avoiding gas waste and reducing operating costs. The drive component 19 is opened, and the output end of the drive component 19 drives the half gear 20 to rotate, which in turn drives the full gear 21 that is meshed on the side to rotate. At this time, the full gear 21 drives the impact plate 24 to rotate through the rotating shaft 22, so that the impact plate 24 strikes the ash discharge channel 1, which can effectively shake off the stubborn material adhering to the inner wall of the ash discharge channel 1. Through the cooperation of vibration and nozzle 18, the overall ash discharge efficiency is improved, and the maintenance workload and maintenance costs are reduced. Since a torsion spring 23 is provided on the outside of the rotating shaft 22, when the half gear 20 continues to rotate and leaves the surface of the full gear 21, the rotating shaft 22 causes the impact plate 24 to return to its initial position through the rebound of the torsion spring 23, which facilitates the impact plate 24 to strike again and generate vibration. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
