Fuel feed system of ceramic kiln adopting dilute phase pneumatic conveying

The utility model provides a fuel feed system of a ceramic kiln adopting dilute phase pneumatic conveying, which adopts solid power as fuel, and comprises a powder conveyer, a powder storage bin, a compressed gas storage tank, a powder blowing tank, a primary fluidization mixer, a secondary fluidization lower discharging type conveyer, a frequency conversion adjusting feeding machine, a cubic fluidization adjuster, a powder diverter and a solid powder combustor. The powder conveyer conveys solid powder fuel to the powder storage bin through a powder conveying pipeline, and conveys powder from the powder storage bin to the tapered part of the powder blowing tank through a blanking pipe; the powder and conveying gas medium are fluidified and mixed by the primary fluidization mixer at the tapered part for the first time, and by the secondary fluidization lower discharging type conveyer the second time; afterwards, the powder and the conveying gas medium enter the frequency conversion adjusting feeding machine, and is conveyed into the cubic fluidization adjuster uniformly and then to a powder fluidization diverter through a powder blowing pipe; the powder fluidization diverter is provided with a plurality of openings; and the powder is blown into the ceramic kiln through the solid powder combustor after being distributed uniformly for the openings.
