AI Technical Summary

Technical Problem

During the aluminum foil rolling process for batteries, the generation of oil mist leads to a decline in product quality, equipment pollution, increased production costs, and environmental health hazards. Existing recycling methods have failed to effectively solve the problem of oil mist generation.

Method used

A funnel device is installed below the scrap trolley, combined with a cooling chamber and a temperature sensor. By slowing down the rolling oil flow rate and lowering the temperature, the oil temperature is controlled by circulating cooling water to prevent oil mist generation.

Benefits of technology

It effectively reduces oil mist generation, lowers production costs, improves equipment cleanliness and environmental hygiene, and enhances product quality.

Abstract

The utility model belongs to aluminium foil rolling technical field especially, it is a kind of device that controls battery aluminium foil rolling mill oil mist, including the funnel device of being set in the scrap car below, the scrap car includes the filter screen device and tray sequentially set from top to bottom, the tray bottom side is provided with oil outlet hole, the position of funnel device and filter screen device corresponds, the inside of funnel device is provided with cooling cavity for the cooling medium of being used to go in, the bottom side of funnel device is provided with several oil discharge pipe. Through the funnel device of adding, the speed of rolling oil flow to ground is slowed down, and the rolling oil temperature is reduced, and the generation of oil mist is greatly reduced, through the cooling water circulation of being set, the rolling oil temperature is reduced, prevents the generation of oil mist. After the rolling oil is slowed down and is cooled, to the bottom side oil discharge pipe, can make the rolling oil flow to ground when reducing the difference, does not produce splashing, prevents the generation of oil mist.
