The common methods mainly include two kinds: the first is heavy hammer airlock flap valve type, and the second is star-type discharger type.

[0003] The heavy hammer airlock flap valve type uses the weight of material to automatically discharge ash. The valve plate is automatically opened under the action of material gravity, and the valve plate is automatically reset by the counterweight lever system after the material falls, to prevent wild wind from blowing in, thereby completing the material conveying. The disadvantage is that the flap is easily deformed under the long-term scouring of material under high temperature, causing blockage after the castable of ash-collecting chamber falls off, affecting production.

[0004] The star-type discharger type relies on the operation of motor to discharge material from the bin through the rotating star-type impeller. The star-type impeller is provided with a plurality of blades, which carry out material in the rotating process. The material falls under the action of gravity to complete the discharging process.
