Driven shaft of rotating anode electrostatic precipitator

The utility model relates to a driven shaft of a rotating anode electrostatic precipitator. The driven shaft of the rotating anode electrostatic precipitator comprises a connecting pipe, wherein two ends of the connecting pipe are fixedly connected with connecting shafts; at least two lock devices for locking the corresponding connecting shafts on the connecting pipe are arranged at two ends of the connecting pipe. The driven shaft of the rotating anode electrostatic precipitator has the advantages that the two connecting shafts are respectively fixed at two ends of the connecting pipe to assemble the driven shaft through the lock devices, so that the machining technology for machining the traditional solid round tube is effectively improved; the driven shaft is short in production period, low in production cost, good in practical performance, simple to operate, and reliable to connect; the change of the length of the driven shaft can be met just by changing the length of the connecting pipe.
