The invention discloses a uniform material spraying type reaction kettle. The uniform material spraying type reaction kettle comprises a tank body, an upper cover, a motor, a rotary shaft, an
impeller, an isolation cover, a pressure equalizing
pipe, a ventilation cap and a material spraying mechanism; when the uniform material spraying type reaction kettle works, reaction liquid is input through a liquid inlet connector; the motor drives the
impeller to rotate through the rotary shaft, so that the reaction liquid is stirred; meanwhile,
powder falls into a material mixing
pipe through a material collection funnel and
compressed air is pumped in through a blowing
pipe; the high-pressure air is used for blowing out the
powder falling from the material collection funnel through a second material leaking hole formed in the material mixing pipe and a first material leaking hole formed in a main pipe in sequence; the
powder in the tank body is dispersed and falls off due to gravity; the reaction liquid and the powder are uniformly mixed under the stirring of the
impeller. The device is simple in structure and can be used for automatically dispersing and spraying out the powder, so that the powder is uniformly dispersed; the powder and the reaction liquid are sufficiently mixed through mechanical stirring and the reaction efficiency is improved; meanwhile, the
utilization rate of the powder is improved.
