Description

Technical Field

[0001] The utility model relates to the technical field of electric dust removal, in particular to the technical field of vibration transmission devices. Background Art

[0002] The electrostatic precipitator is an essential supporting equipment for thermal power plants. Its function is to remove particulate dust in the exhaust gas. It is an important environmental protection equipment to improve environmental pollution. Its working principle is that when the flue gas passes through the main structure of the electrostatic precipitator, the dust is positively charged, and then the flue gas enters the electrostatic precipitator channel with multiple layers of cathode plates. Due to the mutual adsorption between the positively charged dust and the cathode plate, the particulate dust in the flue gas is adsorbed on the cathode and hits the cathode plate regularly.

[0003] In order to achieve long-distance transmission, the existing vibration transmission device is composed of multiple transmission shafts, and the torque between the transmission shafts is provided only by the welds. During the transmission process, a slight jam in some parts will cause the weld to tear and fail. After the weld tears and fails, subsequent transmission cannot be carried out, resulting in the inability to vibrate the dust collector. Utility Model Content
