Electric precipitator and ash removing mechanism thereof

Abstract

The invention discloses an electric precipitator and an ash removing mechanism thereof. The ash removing mechanism comprises two ash removing brushes used for being arranged on the two sides of a dust collection anode plate, and further comprises a pivoted piece used for being connected with a shell of the electric precipitator in a pivoted mode through a pivoted shaft, the two ash removing brushes are arranged at the two ends of the pivoted piece respectively, and the moment of force of one of the two ash removing brushes on the pivoted shaft is larger than the moment of force of the other ash removing brush on the pivoted shaft. Compared with the prior art, the lever principle is used, the moments of force (fulcrums) of the two ash removing brushes on the pivoted shaft are guaranteed to be unequal, the pivoted piece can rotate relative to the pivoted shaft, and the two ash removing brushes are made to be always tangent to the corresponding dust collection surface of a dust collection anode. Therefore, the problem that the gaps between the ash removing brushes and the dust collection surface can not be adjusted after the ash removing brushes are abraded in the prior art is solved, a power component used for driving the ash removing brushes to rotate and a rotary sealing connection structure of the ash removing brushes and the shell are also removed, thus, the whole manufacturing, maintaining and operating cost of the electric precipitator is lowered, and the risk of air leakage at the rotary sealing connection position is avoided.

Description

technical field [0001] The invention relates to the technical field of electric dust collectors, in particular to an electric dust collector and a cleaning mechanism thereof. Background technique [0002] The electrostatic precipitator includes a shell with an air inlet and an air outlet, an ash hopper communicated with the shell, and a fixed anode dust collector and a mobile anode dust collector arranged in the shell along the airflow direction; wherein the mobile anode dust collector includes a The dust-collecting anode plate distributed in the loop, the cathode frame arranged in the loop to form an electric field with the dust-collecting anode plate, the driving mechanism that drives the dust-collecting anode plate to move relative to the cathode along the loop, and the The dust cleaning mechanism is used to remove the accumulated dust on the dust collection surface of the anode dust collection plate and keep the dust collection surface clean, so as to prevent the occurre...
