The battery drying system comprises a drying box, a buffer box, a collecting box and a vacuum pump, wherein batteries are arranged in the drying box, a release unit is arranged on the collecting box, the drying box is in sealing connection with the buffer box through a vacuum pipe, the buffer box is in sealing connection with the vacuum pump through a vacuum pipe and is in sealing connection with the collecting box through a switch valve A, and the collecting box is in sealing connection with the release unit through a switch valve B.
Description
Technical field
The utility model relates to a kind of battery drying system.
Background technology
The characteristics such as that lithium ion battery has is many than high energy density, memory-less effect, cycle-index, long service life, broken away from the various shortcoming of traditional lead accumulator; But because the production technology of lithium ion battery is comparatively complicated, particularly the stoving process of battery in formation process is particularly important, if using traditional technique is dried lithium ion battery, can cause water content too high, cause the internal resistance of cell to increase, thereby reduce the serviceability of lithium ion battery.
At first existing lithium ion battery stoving process puts into battery the drying plant of sealing, then by pipeline, the steam of generation is delivered in baffle-box by the effect of vavuum pump, finally again baffle-box is carried out to dehumidifier, the steam that further will accumulate in baffle-box is drained; Traditional drying technology can not be found time the steam of generation fully, and extraneous air may be brought in drying plant, and the lithium ion battery changed into is worked the mischief; Finally cause the lithium ion battery water content produced too high, finally affect the service life of whole battery pack.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, a kind of battery drying system is provided, it comprises baking oven, baffle-box, collecting box and vavuum pump, on described collecting box, releasing unit is set, described baking oven is tightly connected by vacuum tube and baffle-box, described baffle-box is tightly connected by vacuum tube and vavuum pump, and described baffle-box is tightly connected by switch valve A and collecting box, and described collecting box is tightly connected by switch valve B and releasing unit.
In above-mentioned battery drying system, need the battery of drying to be placed in baking oven.
Use above-mentioned battery drying system to carry out drying operation to battery, inner moisture is heated into to steam, vavuum pump is evacuated to baffle-box by the steam of oven interior, finally in baffle-box, be condensed into aqueous water, after drying course finishes, open the current direction collecting box in baffle-box after switch valve A, after treating that collecting box retaining process finishes, open switch valve B, the water in collecting box is discharged whole system by releasing unit.
As preferably, described switch valve A is in normally off.
Switch valve A, at most of the time of whole drying course closure state, after drying course finishes, just opens switch valve A, and the moisture in baffle-box is discharged; Avoid air and steam in collecting box to enter in baffle-box.
As preferably, described switch valve A comprises check valve.
Use check valve can effectively prevent that as switch valve A steam and air from pouring in down a chimney into baffle-box.
As preferably, described switch valve B comprises check valve.
Use check valve can effectively prevent that as switch valve B steam and air from pouring in down a chimney into collecting box.
As preferably, in described baffle-box, cooling device is set.
Cooling device is set in baffle-box, and the steam liquefaction that can will extract out from drying baker quickly, save process time, increases efficiency.
As preferably, described collecting box is in negative pressure state.
By the collecting box setting, in negative pressure state, the moisture of being convenient in baffle-box is discharged, and also can reduce the pollution of collecting box to baffle-box simultaneously.
After using the technical solution of the utility model, drying course has greatly reduced the moisture entrapment in lithium ion, has improved the efficiency that lithium ion battery is dried; Reduce the interference of outside air to drying system simultaneously, improve the quality of lithium ion battery, increased cycle life.
The accompanying drawing explanation
Fig. 1 is the battery drying system schematic diagram disclosed according to an embodiment of the present utility model;
Wherein, 1, baking oven, 2, baffle-box, 21, cooling device, 3, collecting box, 4, vavuum pump, 5, releasing unit, 6, switch valve A, 7, switch valve B.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, native system comprises baking oven 1, baffle-box 2, collecting box 3 and vavuum pump 4, battery is arranged in baking oven 1, baking oven 1 seals with respect to the system outside, prevent that outside air or steam from causing secondary pollution to battery, baking oven 1 is tightly connected by vacuum tube and baffle-box 2, baking oven 1 and baffle-box 2 internal communication, the gas of baking oven 1 inside can circulate between baffle-box 2 and baking oven 1, baffle-box 2 is tightly connected by vacuum tube and vavuum pump 4, when vavuum pump 4 is started working, baffle-box 2 will be in negative pressure state, at an easy rate by the steam suction baffle-box 2 in baking oven 1, 21 pairs of water vapor condensations of the cooling device of baffle-box 2 interior settings, steam all is condensed into aqueous water and is stored in baffle-box 2 the most at last.
Baffle-box 2 is tightly connected by vacuum tube with collecting box 3, make baffle-box 2 and collecting box 3 internal communication, switch valve A6 is set simultaneously on this section vacuum tube, when baffle-box 2 during in the course of work of being bled, switch valve A6 is in closed condition, in the time need to being discharged the aqueous water in baffle-box 2, open switch valve A6, due to collecting box 3 in negative pressure state, aqueous water enters in collecting box 3 at an easy rate, releasing unit 5 also is set on collecting box 3, and between releasing unit 5 and collecting box 3, switch valve B7 also is set, switch valve B7 is in normally off, only have when the water in collecting box 3 is discharged and just need to open, switch valve A6 and switch valve B7 adopt check valve.
