Vacuum oven capable of heating fast

Abstract

A vacuum oven capable of heating fast comprises a working box body (2) mounted in an oven main body (1) and a heating device (3) arranged outside the working box body (2) and used for replenishing heat for heat dissipation on the outer wall of the working box body (2); the working box body (2) is a high-vacuum resistant and high-pressure resistant working box body. The vacuum oven capable of heating fast has the advantages of short heating time and high utilization ratio of the box body.

Description

technical field [0001] The invention relates to a vacuum oven capable of rapidly raising temperature suitable for baking new energy materials, in particular to a vacuum oven capable of rapidly raising temperature suitable for baking lithium-ion batteries or battery pole pieces. Background technique [0002] In the production process of new energy materials, if necessary, the new energy materials should be baked to remove water, such as the manufacture of lithium-ion battery pole pieces or lithium-ion batteries, it is necessary to dry the lithium-ion battery pole pieces or lithium-ion batteries Tumble dry deep. The most common drying equipment is the internal circulation single box oven, which first puts the baked lithium battery or battery electrode into the vacuum oven, and under normal pressure, first puts the baked lithium battery or battery electrode into the vacuum oven. The baking material is heated. When the temperature in the box reaches the requirement, the box is ...

AI Technical Summary

Problems solved by technology

However, this double-circulation vacuum oven adopts the method of heating up under normal pressure. Generally, it takes about 24 hours from feeding to discharging to complete the complete baking of the baked object, which takes a long time. , the box utilization rate is not high
