Disclosed is an apparatus for efficiently pretreating and recycling a waste battery, which includes a bottom plate, a recycling device, a conveying device and a treatment device, and one end of a top portion of the bottom plate is fixedly mounted with a bottom portion of the conveying device. According to the invention, by arranging a fixing assembly and the recycling device, a suction pump can suck a slurry and an electrolyte in a battery downwardly for dropping, and a driving assembly can rapidly convey the slurry and the electrolyte in the battery to the treatment device for treatment at the same time.

The disclosure relates to a sealing tool for a packaging machine which comprises a tool lower part with at least one centrifugal separator for separating a particle-laden gas flow. The disclosure further relates to a method for separating a particle-laden gas flow at a sealing tool of a packaging machine, where the particle-laden gas flow is separated by way of a centrifugal separator provided at a tool lower part of the sealing tool.
