AI Technical Summary
Technical Problem
In existing technologies, the blowing and washing process for cylindrical lithium batteries occupies a large space and is difficult to avoid secondary pollution.
Method used
A cleaning mechanism including a cleaning pipe, an inlet pipe, and an outlet pipe was designed. The cleaning pipe is equipped with a spiral guide plate and an annular elastic diaphragm. The airflow is spiraled downward between the spiral guide plate and the outer peripheral surface of the lithium battery. Combined with the sealing and scraping functions of the elastic diaphragm, the outer surface of the lithium battery is cleaned.
Benefits of technology
It improves cleaning efficiency, reduces space occupation, avoids secondary pollution, and achieves the dual effects of blowing and scraping.

Abstract
The utility model provides a purging mechanism for a cylindrical lithium battery, and belongs to the technical field of lithium battery processing. Comprising a purging pipe, a feeding pipe and a discharging pipe, the feeding pipe and the discharging pipe are connected to the two ends of the purging pipe respectively, a spiral guide plate is arranged in the purging pipe, and the feeding pipe and the discharging pipe are each provided with an annular elastic membrane; in a natural state, the aperture of the middle through hole of the elastic membrane is smaller than the outer diameter of the cylindrical lithium battery; an air inlet connecting pipe and an exhaust connecting pipe are respectively arranged at two ends of the purging pipe; and the air inlet connecting pipe is connected with an air outlet end of an air pump. The cleaning device has the advantages of good cleaning effect and the like.
