AI Technical Summary

Technical Problem

During the battery electrolyte filling process, especially in the secondary filling stage, the establishment of a vacuum environment causes electrolyte to flow into vacuum pipelines, filters, vacuum pumps, and other equipment, resulting in equipment corrosion and affecting service life and working performance.

Method used

Design a gas-liquid separation device, comprising a shell, a separation chamber, a liquid collection chamber, and an exhaust chamber. The device utilizes a spiral structure for gas-liquid separation, achieving primary separation through the spiral structure providing a condensation surface and centrifugal force, and secondary separation through a filter to prevent electrolyte crystallization and blockage inside the device.

Benefits of technology

It achieves efficient separation of gas-liquid mixtures, reduces the risk of equipment corrosion by electrolyte, and improves equipment lifespan and performance.

Abstract

This application discloses a gas-liquid separation device and a battery production line, relating to the field of battery production equipment technology. The gas-liquid separation device includes a shell and a spiral structure. A separation chamber, a liquid-gathering chamber, and an exhaust chamber are formed within the shell. The outlet of the separation chamber is connected to the inlet of the liquid-gathering chamber, and the outlet of the liquid-gathering chamber is connected to the inlet of the exhaust chamber. The separation chamber and the exhaust chamber are spaced apart above the liquid-gathering chamber. The spiral structure is disposed within the separation chamber, and a separation channel is formed between the outer surface of the spiral structure and the inner wall of the separation chamber. The spiral structure is configured to perform gas-liquid separation on the mixture flowing through the separation channel. The inlet size of the separation chamber is smaller than the outlet size. This application enables efficient separation of gas-liquid mixtures, avoids electrolyte crystallization and blockage inside the equipment, reduces the risk of electrolyte corrosion, and improves the service life and performance of the equipment.
