Problems solved by technology

Such equipment and water removal process are not easy to completely remove water from the pole piece and the battery cell, and the time is long and the efficiency is low
In order to improve the water removal effect, some people changed to remove water under continuous vacuum, which brought many problems: first, there is no gas in the working chamber of the liner under vacuum, and the heat transfer is basically a radiation mode. In a

Embodiment 1

[0029] A single-door vacuum oven, the inner tank is made of 4mm thick stainless steel, the heating method is 4+1, the door is assisted in heating, and the heating element adopts a serpentine electric heating tube. An exhaust hole is opened on its rear wall, and an air intake hole is opened on the side. According to attached figure 1 In the best way, connect the vacuum pump, two-way valve, water removal unit, and nitrogen input pipeline with pipelines with good sealing performance. The water removal unit is a sealed stainless steel tank loaded with 4A molecular sieve. This constitutes the vacuum oven of the present invention.

Embodiment 2

[0031] Replace the water removal unit with two parallel sealed stainless steel tanks loaded with 4A molecular sieves, according to the attached figure 2 The mode is connected, and all the other are the same as embodiment one.

Abstract

The invention proposes a vacuum oven with a circulating dewatering system, and proposes the circulating dewatering system of the vacuum oven. A circulating water removal system is set outside the inner tank of the oven, which is mainly composed of a pipeline, a circulating pump and a water removal unit. Back to the interior of the liner, the technical solution of the present invention does not need to be continuously maintained in a high vacuum state, which overcomes the difficulty of heating in a vacuum state, can effectively and conveniently remove trace moisture from the baking object, and saves a lot of nitrogen. The invention is convenient to implement and has obvious effects.

Description

technical field [0001] The invention relates to a vacuum oven and a water removal system thereof. Background technique [0002] Vacuum ovens are widely used in industrial and scientific experiment fields. In the manufacture of lithium-ion batteries, vacuum ovens are essential equipment, and their performance directly affects the quality, performance and production line capacity of batteries. With the development of digital technology, a large number of digital products have developed rapidly and become popular, which has brought great development in the application of lithium-ion batteries. In addition, lithium-ion batteries are still the preferred energy source for electric vehicles, and electric vehicles consume a large amount of batteries; with the approach of the era of electric vehicles, the future will definitely promote greater development of lithium-ion battery applications. [0003] When the current vacuum oven bakes pole pieces and batteries, the standard method ...
