AI Technical Summary

⚠Technical Problem

In existing electrostatic precipitators, the rapping shaft is prone to deformation or bending when rapping the electrode plates, which shortens its service life and makes it impossible to hit accurately, affecting the working stability of the electrostatic precipitator.

⚗Method used

It adopts a combination design of striking mechanism and actuation mechanism, including L-shaped striking hammer, striking post, return spring and lever. The lever is driven by a drive motor to rotate, and the dual action of gravity and spring is used to achieve precise striking and avoid deformation of lever and striking hammer.

🎯Benefits of technology

This enables stable and continuous dust removal operation of the electrostatic precipitator, extends the service life of the device, ensures uniform and efficient energy output for each impact, and improves the durability and working efficiency of the device.

Abstract

This utility model discloses a vibratory dust removal device for an electrostatic precipitator, comprising an electrode plate, several striking mechanisms, and a toggle mechanism. The striking mechanism includes a support base fixed to the electrode plate by bolts, an L-shaped striking hammer hinged to the support base, a striking post located below the L-shaped striking hammer and fixed to the electrode plate by bolts, and a return spring connected at one end to the L-shaped striking hammer and at the other end to the striking post. The toggle mechanism includes a reduction gearbox fixedly installed to the internal frame of the electrostatic precipitator, a drive motor mounted on the reduction gearbox and connected to the reduction gearbox at its output end, a drive shaft extending from the output end of the drive motor, a lever fixedly connected to and parallel to the drive shaft, a driven shaft fixedly installed at the other end of the lever and aligned with the drive shaft, and a driven shaft mounting seat with a built-in bearing housing fixedly installed to the internal frame of the electrostatic precipitator. This device, through the cooperation of the striking mechanism and the toggle mechanism, effectively removes dust from inside the electrostatic precipitator.
