DETAILED DESCRIPTION
[0019] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts belong to the range protected by the utility model.
[0020] As Figure 1 The utility model provides a technical scheme: a cement kiln head waste heat boiler dust discharging system, including waste heat boiler 1, the lower discharge port position of this waste heat boiler 1 is provided with main road dust discharging channel 2 and bypass dust discharging channel 3 (two dust discharging channels, one opens one and closes, switches and uses), wherein, main road dust discharging channel 2 and the lower part of waste heat boiler 1 are provided with observation port 4.
[0021] The lower part of waste heat boiler 1 is provided with vibration motor 15, opens vibration motor 15, can vibrate the bottom of boiler, this helps the smooth discharge of ash material.
[0022] Main road dust discharging channel 2 is provided with main road air cannon 8, and the top of bypass dust discharging channel 3 is provided with bypass air cannon 11, and the purpose of setting air cannon is to use high pressure to scatter the ash material that has been caked and prevent it from being blocked.
[0023] The main road dust discharge passage 2 is respectively provided with a main road pneumatic gate valve 5, a rotary feeder 6 and a main road thermal resistance 7, and the main road thermal resistance 7 is linked with a bypass pneumatic gate valve 9, so that when the main road dust discharge passage 2 is blocked, the bypass dust discharge passage 3 can be opened in time.
[0024] The bypass dust discharge passage 3 is respectively provided with a bypass pneumatic gate valve 9 and a bypass thermal resistance 10.
[0025] The bottom of the main road dust discharge passage 2 and the bypass dust discharge passage 3 is communicated with a dust conveying zipper machine 16.
