Blockage removing auxiliary device of rotatable air pre-heater

The utility model discloses a rotatable air pre-heater unblocking auxiliary device which comprises a first motor, a rotating shaft is fixedly connected to the first motor, a rotating shaft coaxial with an output shaft is fixedly connected to the output shaft of the first motor, and the first motor is arranged so that the device can be used in the normal operation process of an air pre-heater. The rotating speed of the first motor is controlled to be consistent with that of a rotor of the air pre-heater, so that the device and the air pre-heater synchronously rotate, and when the air pre-heater works, the device can carry out dust removal work, and the working efficiency of the air pre-heater is prevented from being influenced; besides, the device can also be used during regular ash removal and can assist a soot blower in removing blockage of a sector area of the heat storage plate, and the blockage risk of the air pre-heater and the running resistance of the air pre-heater are effectively reduced; and a secon
