Anti-blocking discharging device

The utility model relates to an anti-blocking discharging device, which belongs to the field of chemical production equipment and is characterized in that centrifugally dehydrated piperazine pyrophosphate is dried by a hot air pipeline and then fed into an air jet mill for production, the hot air pipeline comprises a feeding pipe and a discharging pipe, a fan and an electric heater are arranged on the side of the feeding pipe, and the electric heater is arranged on the side of the discharging pipe. Hot air heated by the electric heater enters the feeding pipe from the air inlet pipe, the spiral feeder is arranged beside the feeding pipe, piperazine pyrophosphate subjected to centrifugal dewatering is fed from the feeding pipe and fed into the feeding pipe through the spiral feeder, the hot air enters the feeding pipe to blow powder upwards, and the powder is dried in the upward blowing process. Powder enters the cyclone separator to be recycled after passing through the feeding pipe and the discharging pipe,
