Fire grate used by household garbage flash evaporation mineralization processor

The invention discloses a fire grate used by a household garbage flash evaporation mineralization processor, and relates to a household garbage processing device assembly. The fire grate is a movablefire grate capable of rotating by 360 degrees, and comprises a fire grate shell, a rotating shaft, a chain wheel set, a speed reduction transmission mechanism capable of being driven through a fire grate motor, a honeycomb-shaped ceramic body with the pyroelectric effect and a permanent magnet. Air holes are evenly formed in the fire grate shell, the rotating shaft penetrates the fire grate shell,the two ends can be rotatably arranged on a furnace body, one end of the rotating shaft is connected with the speed reduction transmission mechanism through the chain wheel set, the permanent magnetand the honeycomb-shaped ceramic body are arranged in the fire grate shell alternatively, and the N pole and the S pole of the permanent magnet are assembled in an opposite and spaced manner to buildan original magnetic field.
