[0006] Preferably, the ash cleaning device consists of a coal spreading air main pipe and a connecting pipe, one end of the connecting pipe is connected to the coal spreading air main pipe, and the other end is installed in a corresponding connecting hole on the ash cleaning channel, and a valve is provided on the connecting pipe for controlling opening and closing.
[0007] Preferably, the connecting pipe is composed of a stainless steel pipe and a metal bellows, wherein one end of the stainless steel pipe is connected to the coal spreading air main pipe, and the other end is connected to the metal bellows, and the metal bellows is threadedly connected to the connecting hole through a thread, and a sealing ring is provided on the connecting hole to ensure the overall airtightness.
[0008] Preferably, the valve is a manual gas valve or an electric valve, and a pressure monitoring gauge is provided on the connecting pipe for real-time monitoring of the pressure in the pipe.
[0009] The beneficial effects of the utility model are as follows:
[0010] The electric gate door with a ash cleaning device designed by the utility model takes pressure from the coal-spreading air main pipe, and introduces it into the rear of the electric gate door through a stainless steel pipe, a manual air valve switch, and a stainless steel metal hose. Under normal boiler operation, the coal-spreading air is in a smooth state. During operation, the manual air valve is manually opened to maintain a long-term ash cleaning state. The manual valve is closed when the fire is suppressed or the boiler is shut down, thereby effectively preventing the electric gate door from being in an open state during operation, which will cause a large amount of coal ash to accumulate at the rear over time and affect the transmission system inside, thereby improving the overall service life. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a schematic diagram of the overall structure of the utility model. DETAILED DESCRIPTION
[0012] In order to enable those skilled in the art to more clearly understand the purpose, technical solutions and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments.
[0013] In the description of the present invention, it should be understood that the orientations or positional relationships indicated by terms such as "upper", "lower", "left", "right", "inside", "outside", "horizontal", and "vertical" are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or original referred to must have a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.
[0014] The present invention will be described in detail below with reference to the accompanying drawings: Figure 1 As shown, an electric gate door with a cleaning device includes an electric gate door 2 installed on a coal feeding channel 1, a feeding port 3 is provided on one side of the coal feeding channel 1, and the feeding port 3 is opposite to the dropping place of the coal feeder of the coal bin (not shown in the figure), and a coal discharge port 4 is provided at the bottom of the coal feeding channel 1, and an electric gate door 2 is installed on the coal feeding channel 1 near the coal discharge port 4. The coal discharge amount is controlled by opening or closing the electric gate door 2, and a closed ash cleaning channel 6 is provided on one side of the electric gate door 2 on the coal feeding channel 1, and a ash cleaning device is installed on the ash cleaning channel 6. The ash cleaning device is used to remove coal ash accumulation in the coal feeding channel 1, thereby improving the utilization efficiency of the electric gate door 2.
[0015] The ash cleaning device consists of a coal spreading air main pipe 7 and a connecting pipe 8. One end of the connecting pipe 8 is connected to the coal spreading air main pipe 7, and the other end is installed in a corresponding connecting hole 10 on the ash cleaning channel 6. A valve 5 is provided on the connecting pipe 8 for controlling opening and closing.
[0016] The connecting pipe 8 is composed of a stainless steel pipe 11 and a metal bellows 12. One end of the stainless steel pipe 11 is connected to the coal spreading air main duct 7, and the other end is connected to the metal bellows 12. The metal bellows 12 is threadedly connected to the connecting hole 10, and a sealing ring 13 is provided on the connecting hole 10 to ensure overall airtightness. The connecting pipe of the utility model is composed of a stainless steel pipe and a metal bellows. The stainless steel pipe ensures the overall strength of the connecting pipe, while the metal bellows ensures the deformation resistance of the connection.
[0017] Furthermore, metal bellows can compensate for thermal expansion and contraction caused by temperature changes in pipelines, thereby reducing pipeline stress and protecting the pipeline system. They can also absorb equipment vibration, reducing its impact on pipelines, thereby greatly improving overall safety and practicality.
[0018] The valve 5 is a manual air valve or an electric valve, and a pressure monitoring gauge 9 is provided on the connecting pipe 8 for real-time monitoring of the pressure in the pipe. Of course, a temperature monitor or other installation device can also be provided on the connecting pipe, and an alarm device can be added to ensure the safety of the equipment during use.
[0019] The electric gate door with a ash cleaning device designed by the utility model takes pressure from the coal-spreading air main pipe, and introduces it into the rear of the electric gate door through a stainless steel pipe, a manual air valve switch, and a stainless steel metal hose. Under normal boiler operation, the coal-spreading air is in a smooth state. During operation, the manual air valve is manually opened to maintain a long-term ash cleaning state. The manual valve is closed when the fire is suppressed or the boiler is shut down, thereby effectively preventing the electric gate door from being in an open state during operation, which will cause a large amount of coal ash to accumulate at the rear over time and affect the transmission system inside, thereby improving the overall service life.
