Description
Technical field
The utility model relates to a kind of homogenization apparatus of cell positive material, particularly a kind of lithium ion cell positive homogenate V-mixer.
Background technology
Lithium ion battery is because of the advantage such as monomer whose output voltage is high, specific energy is high, the life-span is long and self-discharge rate is low, and in Battery Market, obtain quick propelling, some manufacturers start to expand the scale of production.
Homogenate operation provides electrode material slurries, is the head end link in lithium ion battery production process, is also very important link.It had both govern the length of production cycle, had material impact again to properties of product.Existing positive pole homogenization process, have employed adhesive supplier and homogenate pot two kinds of equipment, is first disperseed in a solvent by binding agent in adhesive supplier, make glue, 2 ~ 3 hours this step used times, then colloid is transferred in homogenate pot, in homogenate pot, add conductive agent more simultaneously, stir after 2 ~ 3 hours, add major ingredient 1 and partial solvent, disperse after 0.5 hour, add major ingredient 2 and residual solvent again, above process needs regular scraper, after material all adds, continues stirring 3 ~ 4 hours.The total duration of this process is 7.5 ~ 10.5 hours.This method excessive cycle, and complex operation, be not suitable for the need of production of expanding day.
Utility model content
The utility model provides a kind of lithium ion cell positive homogenate V-mixer, this device can simplify anode sizing agent homogenate operation operating procedure, shorten the homogenate cycle, improve production efficiency and product quality.
The utility model solves the technical scheme that its technical problem adopts:
A kind of lithium ion cell positive homogenate V-mixer, comprise support, V-type barrel and drive unit, V-type barrel is rack-mount by horizontally disposed rotating shaft, rotating shaft is driven by drive unit and rotates, V-type barrel inside is provided with shaft and is driven the stirrer paddle rotated by shaft, and the longitudinal section of V-type barrel is V-type.The existing built-in stirrer paddle being parallel to direction, ground of V-mixer, can rotate in self vertical ground direction again under the drive of drive unit.
As preferably, V-type barrel is provided with at least one feed inlet and outlet.
As preferably, symmetrical structure centered by V-type barrel, described shaft is installed on axle center, the bottom place of V-type barrel, and described stirrer paddle horizontal direction is arranged.
The beneficial effects of the utility model are: the existing built-in stirrer paddle being parallel to direction, ground of V-mixer, can rotate in self vertical ground direction again.Electrode dry mash can mix by the effect of this superposition fast, simplifies operating process, shortens the homogenate cycle, improve production efficiency, and can improve the degree of scatter of slurries, then improve the quality of product.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model;
In figure: 1, support, 2, V-type barrel, 3, drive unit, 4, rotating shaft, 5, shaft, 6, stirrer paddle, 7, feed inlet and outlet.
Detailed description of the invention
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.Should be appreciated that enforcement of the present utility model is not limited to the following examples, any pro forma accommodation make the utility model and/or change all will fall into the utility model protection domain.
In the utility model, the formula of electrode dry mash is routine techniques, and therefore non-research emphasis of the present utility model does not describe in detail.
Embodiment:
V-mixer as shown in Figure 1, comprise support 1, V-type barrel 2 and drive unit 3, V-type barrel is rack-mount by horizontally disposed rotating shaft 4, rotating shaft is driven by drive unit and rotates, V-type barrel inside is provided with shaft 5 and is driven the stirrer paddle 6 rotated by shaft, and the longitudinal section of V-type barrel is V-type.The existing built-in stirrer paddle being parallel to direction, ground of V-mixer, can rotate in self vertical ground direction again under the drive of drive unit.V-type barrel top is provided with 2 feed inlet and outlets 7.V-type barrel angle is 80o; Barrel diameter 40cm; Stirrer paddle diameter 2cm, the surface soldered of stirrer paddle has the bifurcated that can promote to stir; The most high rotation speed 120r/min of mixer, can determine angle and stop.
Electrode dry mash is major ingredient LiMn2O4 and nickel-cobalt-manganese ternary material, binding agent PVDF, conductive agent Super-P and Ks-6, and organic solvent is NMP.
By electrode dry mash by after feed inlet and outlet material loading, open shaft, make the built-in stirrer paddle work being parallel to direction, ground, opening of rotary shaft, makes V-mixer self carry out vertical ground direction and rotates simultaneously.After stirring 45 minutes with the speed of 60r/min, with vertical ground (90o) arrestment, the electrode dry mash of mixing is put in homogenate pot by feed inlet and outlet, stir after adding part organic solvent, after 30 minutes, add remaining organic solvent, and continue stirring 3 hours.The addition of organic solvent regulates according to scene, and general control every batch adds the organic solvent about half.Test slurry viscosity, sieves after meeting the requirements, namely obtains the positive pole slurries for next operation.
The utility model has the advantage of and stir ground more thoroughly to dusty material, mixedly more even, the effect of superposition shortens mixing time, improves production efficiency and product quality.Correction data is in table 1.
