Embodiment 1

[0031] The cell drying gas device 100 includes a first adsorption tower 110 and a second adsorption tower 120 and a pipeline 130 connecting the first adsorption tower 110 and the second adsorption tower 120 . Mainly through the operation of the valve set on the pipeline 130, the gas in the first adsorption tower 110 and the gas in the second adsorption tower 120 are dried, and provided to the battery for drying the battery. Core drying device, so that the production line can continuously provide dry gas to the battery cells, without the need to replace the filled dry gas, so that the air supply pressure is more stable, and the gas can be supplied in time to avoid the shutdown of the battery cells due to insufficient dry gas supply Or product quality problems, improve the production efficiency of batteries.

[0032] In this embodiment, a desiccant is provided inside the first adsorption tower 110 and the second adsorption tower 120 to dry the gas, and the desiccant cannot react...

Embodiment 2

[0041] This embodiment provides a cell drying gas system 200, including an air compression system 210, a purification system 220, a first buffer tank 230, and the cell drying gas device 100 provided in Embodiment 1. The air outlet of the air compression system 210 is connected to the The inlet port of the purification system 220 is connected, the gas outlet port of the purification system 220 is connected with the inlet port of the first buffer tank 230, the gas outlet port of the first buffer tank 230 is connected with the pipeline 130 at the first valve 131, and the second valve The cell drying gas at the gas outlet at 132 is used for cell drying.

[0042] Compress the air through the air pressure system 210 first, then purify the air through the purification system 220, and use the first buffer tank 230 to temporarily store it, and then pass it into the cell drying gas device 100 for drying, and finally obtain the cell drying gas Used for cell drying.

[0043] In this embo...

Embodiment 3

[0049] This embodiment provides a method for preparing cell drying gas, using the cell drying gas device 100 provided in Embodiment 1. Including the following steps:

[0050] (1), first open the first valve 131, the third valve 133, the fourth valve 134 and the second valve 132, so that the first valve 131, the third valve 133, the first adsorption tower 110, the fourth valve 134, the second The valves 132 are connected in turn to form the first intake path; (2), then open the first valve 131, the fifth valve 135, the sixth valve 136 and the fourth valve 134, the first valve 131, the fifth valve 135, the second adsorption Tower 120, the sixth valve 136, the fourth valve 134, and the first adsorption tower 110 are connected in sequence to form the first pressure equalization path; (3), then open the first valve 131, the fifth valve 135, the sixth valve 136 and the second The valve 132 makes the first valve 131, the fifth valve 135, the second adsorption tower 120, the sixth va...

Abstract

The invention provides a battery cell drying gas device, a battery cell drying gas system, and a preparation method of a battery cell drying gas, which belong to the technical field of battery cell gas drying. A first valve, a fifth valve, a second adsorption tower, a sixth valve, a fourth valve and a first adsorption tower of the battery cell drying gas device are sequentially communicated to form a first pressure equalizing path; the first valve, a third valve, the first adsorption tower, the fourth valve, the sixth valve and the second adsorption tower are sequentially communicated to forma second pressure equalizing path. A gas outlet end of a purification system of the battery cell drying gas system is communicated with a gas inlet end of a first buffer tank; a gas outlet end of thefirst buffer tank is communicated with a pipeline at the first valve part; a battery cell drying gas of a gas outlet end at the second valve part is used for battery cell drying. According to the preparation method of the battery cell drying gas, the battery cell drying gas system with the battery cell drying gas device is used for drying the gas, and is applied to battery cell drying, so that battery cells are prevented from absorbing moisture under an air pressure, and are dried more conveniently.

Description

technical field [0001] The invention relates to the technical field of cell gas drying, in particular to a cell drying gas device, system and a method for preparing cell drying gas. Background technique [0002] In the prior art, when the battery is dried in the factory, the bottled gas is usually purchased separately, which is expensive, inconvenient to transport, and needs to be manually ventilated. There are often situations where the gas supply pressure is unstable or the gas supply is not timely, which can easily lead to Discontinuation of production or the occurrence of problems that affect product quality. Contents of the invention [0003] The purpose of the present invention is to provide a cell drying gas device capable of obtaining dry gas for drying the cell. [0004] Another object of the present invention is to provide a cell drying gas system, using the above-mentioned cell drying gas device, it is possible to obtain dry gas for drying the cells. [0005] ...
