Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic dust removal, in particular to a vibration device for an electrostatic dust collector. Background Art

[0002] Electrostatic precipitator is a kind of high-efficiency dust removal equipment widely used in industrial production processes. Its working principle is to use a high-voltage electric field to charge the dust particles in the dust-laden gas, and adsorb the charged dust particles onto the dust collecting plate through the action of the electric field force, thereby achieving the purpose of purifying the gas.

[0003] In order to remove dust accumulation on the plates to ensure the normal operation of the dust collector, an electromagnetic vibrating device is usually installed on the top of the electrostatic precipitator. The electromagnetic force is used to lift the vibrating rod to a certain height, and then the vibrating rod is released to fall freely and hit the vibrating point on the plate, causing the plate to vibrate to release the adsorbed dust.

[0004] Electromagnetic vibration usually uses electronic components for the output of vibration power supply and vibration control. Due to the poor stability and anti-interference performance of electronic components, as well as the large high-voltage electric field induced voltage of tens of kilovolts in the electrostatic precipitator body, it is very easy to cause problems such as circuit control parameter voltage / current signal drift and component breakdown. Utility Model Content

[0023] 2. The present application realizes the function of clamping or releasing the rapping hammer by driving the clamping jaws to rotate through a cylinder. The operation of the cylinder is not affected by the electric field and has high stability. The clamping mechanism is driven to rise and fall through a combination of a motor and a gear rack. The motor controls the lifting height of the clamping mechanism, and has high stability and accuracy, and strong anti-interference ability. BRIEF DESCRIPTION OF THE DRAWINGS
