Abstract
The utility model provides a device for drying a lithium battery pole piece. The device comprises a vacuum oven and a heating storage container used for heating inert gases, wherein the vacuum oven is communicated with the heating storage container through a pipeline. The device has the advantages that the heating storage container is arranged on the outer side of the vacuum oven, in the process that the vacuum oven bakes the lithium battery pole piece, the fact that the temperature of the gas entering the vacuum oven is higher than the temperature inside the vacuum oven in gas exchange is guaranteed, therefore, in the process of gas exchange, the fact that trace water vapor suspending in vacuum inside the vacuum oven cannot meet gas coming in through the gas exchange to be again cooled and condensed to be water in a reduction mode is guaranteed, the water vapor produced by baking in the vacuum oven is taken away efficiently, quick drying effects are achieved, and working efficiency is greatly improved.
Description
Technical field
The utility model relates to the lithium battery drying device, relates in particular to the device of dry lithium battery pole piece.
Background technology
In the present existing technology, lithium battery is all finished baking in baking box, generally is in the vacuum bakeout scavenging period, and with nitrogen, the inert gases such as argon gas serve as medium, takes away the steam in the vacuum vacuum drying oven.
At present in the vacuum drying technique, the steam that tends to cause high-temperature baking case inside to be evaporated because of entering of cool ambient air in scavenging period is met the outside cold air of coming in can form liquid condition again, be difficult to be gone out by the inert gas medium belt, so often need a plurality of circulation technologies to process, waste many labours and time.Greatly reduce operating efficiency.
The utility model content
In order to solve the problems of the prior art, the utility model provides a kind of device of dry lithium battery pole piece.
The utility model provides a kind of device of dry lithium battery pole piece, comprises vacuum drying oven, to the heating reservoir vessel that inert gas heats, and described vacuum drying oven and described heating reservoir vessel are connected by pipeline.
As further improvement of the utility model, state the heating reservoir vessel and be the heating holding vessel.
As further improvement of the utility model, the device of this dry lithium battery pole piece also comprises the storage container of storing inert gas, and described storage container is connected with described heating reservoir vessel.
As further improvement of the utility model, the device of this dry lithium battery pole piece also comprises temperature control equipment, the heating-up temperature that described temperature control equipment links to each other with described heating reservoir vessel, also reservoir vessel is heated in control.
The beneficial effects of the utility model are: by heating reservoir vessel one of vacuum drying oven peripheral hardware; so that vacuum drying oven is in baking lithium battery or lithium battery pole slice process; enter the temperature of gas of vacuum drying oven when guaranteeing to take a breath greater than the vacuum drying oven internal temperature; thereby so that in scavenging period; the trace suspension of guaranteeing vacuum drying oven inside can not run into gas that ventilation comes at the steam of vacuum and meet cold again reduction and condense into water; efficiently take away baking steam out in the vacuum drying oven; reach the flash baking effect, greatly increase work efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model discloses a kind of device of dry lithium battery pole piece, comprise vacuum drying oven 1, to the heating reservoir vessel 2 that inert gas heats, described vacuum drying oven 1 and described heating reservoir vessel 2 are connected by pipeline.
By heating reservoir vessel 2 inert gas is heated, the inert gas after then will heating is delivered in the vacuum drying oven 1.
Described heating reservoir vessel 2 is the heating holding vessel.
The device of this dry lithium battery pole piece also comprises the storage container 3 of storing inert gas, and described storage container 3 is connected with described heating reservoir vessel 2.The inert gas of these storage container 3 storages is delivered to heating reservoir vessel 2 and heats, and then the inert gas after will heating is delivered in the vacuum drying oven 1.
Inert gas comprises nitrogen, argon gas.
The device of this dry lithium battery pole piece also comprises temperature control equipment, the heating-up temperature that described temperature control equipment links to each other with described heating reservoir vessel 2, also reservoir vessel 2 is heated in control.
By heating reservoir vessel 2 one of vacuum drying oven peripheral hardware; so that vacuum drying oven 1 is in baking lithium battery or lithium battery pole slice process; enter the temperature of gas of vacuum drying oven 1 when guaranteeing to take a breath greater than vacuum drying oven 1 internal temperature; thereby so that in scavenging period; the trace suspension of guaranteeing vacuum drying oven 1 inside can not run into gas that ventilation comes at the steam of vacuum and meet cold again reduction and condense into water; efficiently take away vacuum drying oven 1 interior baking steam out; reach the flash baking effect, greatly increase work efficiency.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
