The invention discloses an energy-saving
polishing device and a
polishing powder solution recycling method. The energy-saving
polishing device comprises a polishing mechanism, a polishing
powder solution supply mechanism and a polishing
powder solution
recovery mechanism, wherein a polishing region in the polishing mechanism is divided into a pre-polishing region, a rough polishing region and a fine polishing region, and each polishing region is provided with a compression roller and a polishing
brush. The polishing powder solution supply mechanism is composed of a batching tank, a
recovery tank, a polishing powder solution pump, a conveying pipeline and spraying pipes, wherein a polishing powder solution of the batching tank is conveyed to the rough polishing region and the fine polishingregion through the spraying pipes, and through separation by the corresponding compression roller, the used polishing powder solution is respectively collected into the
recovery tank and the batchingtank through a
recovery mechanism. The polishing powder solution in the recovery tank is conveyed to the pre-polishing region through the corresponding spraying
pipe, and through separation by the corresponding compression roller, the re-used polishing powder solution is discharged as a failure polishing powder solution. The energy-saving polishing device can realize cyclic utilization of the polishing powder solution, and the production is not required to be stopped when polishing powder and water are added, so that the production efficiency is improved.
