Abstract
The utility model discloses a stirring system for battery slurry. The system comprises a stirring tank, a low-speed stirring device placed inside the stirring tank, and a quick stirring device placed at the bottom of the stirring tank, and further comprises an external circulation pipeline, wherein the inlet of the external circulation pipeline is connected with the discharge opening of the stirring tank, the outlet of the external circulation pipeline is connected with the feed opening of the stirring tank, and a circulation pump is arranged between the inlet and the outlet of the external circulation pipeline. After the adoption of the structure, when slurrying is started, the low-speed stirring device is started, so as to enable the slurry on the upper layer and the lower layer to be mixed preliminarily; after a certain time, the quick stirring device is turned on to stir the materials on the lower layer, and meanwhile, the circulation pump between the inlet and the outlet of the external circulation pipeline is turned on to convey the materials on the lower layer to the upper layer. Therefore, the purpose of fully mixing the materials on the upper and the lower layers is achieved.
Description
Technical field
The utility model relates to a kind of cell size stirring system.
Background technology
Lithium ion battery have voltage height, specific energy high, recycle often, advantage such as memory time is long; Not only on portable electric appts; Be used widely like mobile phone, DV and laptop computer; And be widely used in big-and-middle-sized electrical equipment aspects such as electric automobile, electric bicycle and electric tool, therefore increasingly high to the performance requirement of lithium ion battery.
Electrode plates is the important component part of lithium ion battery, is important link in the lithium ion battery production process, be the core of lithium ion battery, and the dispersity of cell size has directly determined electrode quality.
In the current battery pulping process, the stirring of cell size mainly by be installed in the agitator tank quick agitating device and at a slow speed agitating device accomplish.Because the agitating device mixing speed is slower at a slow speed, can only tentatively mix cell size, though and agitating device speed is high fast; But because the stirring flabellum of this device is positioned at the bottom of agitator tank, so can only stir lower floor's slurry, it is higher to add cell size viscosity; So; Stir at a slow speed with stirring fast and be difficult to upper and lower layer slurry mixed, especially when the slurry liquid level is higher, is easy to cause slurry to disperse inhomogeneous and makes slurry produce particle; Directly influence electrode quality, serious meeting influences the security performance of battery.
The utility model content
The technical problem that will solve of the utility model provides a kind of cell size stirring system, makes the material of the interior levels of agitator tank fully to mix.
For solving the problems of the technologies described above; A kind of cell size stirring system of the utility model comprises agitator tank, place the inner agitating device at a slow speed of agitator tank and place the quick agitating device of agitator tank bottom; Also comprise the outer loop pipeline; The inlet of described outer loop pipeline links to each other with the discharging opening of described agitator tank, and described outer loop pipeline outlet links to each other with the charging aperture of described agitator tank, is provided with circulating pump between the described outer loop pipeline entrance and exit.
Adopt said structure, during the work beginning, open agitating device at a slow speed, the levels material is tentatively mixed; Behind the certain hour, open quick agitating device, lower floor's material is stirred, open the circulating pump between agitator tank discharging opening and the charging aperture simultaneously, the material of lower floor is transported to charging aperture by discharging opening, thereby reaches the well-mixed purpose of levels material.
As the further improvement of the utility model, be connected with pipeline between the discharging opening of agitator tank and charging aperture and the circulating pump.Like this, can carry out mass transport easily.
The cell size stirring system that the utility model provides, not only be applicable to lithium ion battery produce in to the stirring of cell size, and be applicable to STIRRING OF VISCOUS MATERIALS such as mud, high viscosity grease.
The technical scheme that is provided by the utility model is visible, compared with prior art, the cell size stirring system that the utility model provides, the cell size higher to viscosity can play good stirring action, material is fully disperseed and mixes.
Description of drawings
Fig. 1 is the utility model cell size stirring system structure sketch.
The specific embodiment
In order to understand the technical scheme of the utility model better,, the utility model is done to specify further below in conjunction with accompanying drawing.
When slurrying began, the discharging opening 4 with agitator tank 7 linked to each other with circulating line 6 earlier, opened the agitating device at a slow speed 2 that is positioned at agitator tank 7 inside then; Tentatively stir, open the quick agitating device 1 that places the agitator tank bottom behind the certain hour, stir fast; While ON cycle pump 3; The cell size of agitator tank 7 bottoms via circulating pump 3 and circulating line 6, from charging aperture 5 entering upper strata cell sizes, thereby makes that the interior levels slurry of agitator tank is fully disperseed from discharging opening 4.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
Claims (2)
1. cell size stirring system; Comprise agitator tank, place the inner agitating device at a slow speed of agitator tank and place the quick agitating device of agitator tank bottom; It is characterized in that: also comprise the outer loop pipeline; The inlet of described outer loop pipeline links to each other with the discharging opening of described agitator tank, and described outer loop pipeline outlet links to each other with the charging aperture of described agitator tank, is provided with circulating pump between the described outer loop pipeline entrance and exit.
2. be connected with pipeline between the cell size stirring system according to claim 1, discharging opening and the charging aperture that it is characterized in that described agitator tank and circulating pump.
