In this structural design, the setting of column box provides the space for gear motor's installation, and during the operation, gear motor drives pivot, ring gear pole and rotates the ring gear rotation, rotates the ring gear and drives the gear and carry out the rotation of circumferencial direction rotation and self along fixed ring gear, and then drives the erodeing of brush pole and brush hair to the dirty layer on the negative plate.
The invention has reasonable and reliable structural design, realizes the thorough removal of scale layers on the surfaces of the electrode plates, greatly improves the electrolysis effect, greatly improves the stability in the scouring process, simultaneously avoids the potential safety hazard caused by the fracture of the scraper and the low efficiency caused by the maintenance of the scraper, and has the advantages of reasonable structure, simple processing and low cost.
