Description
Technical field
The utility model belongs to field of battery production, and more particularly to a kind of slurry agitation for lithium battery coating apparatus fills
It puts.
Background technology
In lithium battery production, coating electrode piece is most basic and important production stage, and typical coating process is
Uniform electrode slurry will be pre-mixed and be coated uniformly on metal collector foil surface, form electrode plates after drying, used
In carrying out follow-up battery core process and assemble, in coating apparatus front end, be typically provided the hopper of temporary institute's coating sizing-agent, for immediately into
Capable transfer or squash type coating, due to the self property of electrode slurry, the placement of certain time may lead to internal dispersion material
The sedimentation of material and due to solvent volatilize caused by viscosity rise, in this way can to subsequent electrode be coated with cause process consistency
Variation, the final stabilization for influencing pole piece and battery quality, in order to reduce influence of the viscosity change to product of slurry, is producing
The mobile stirring rod being positioned in slurry tank can generally be used to maintain the stabilization of slurry dispersibility, this simple stirring in the process
Method can play a role, but there is also it is larger the defects of, mixing effect is poor, and control accuracy is low, can not accomplish to glue
The lasting consistency of degree, obtained unstable product quality, yields is low, inconvenient for operation.
The technical problem to be solved by the present invention is to provide a kind of mixing effect is good, control accuracy is high, viscosity is kept to hold
Continuous consistency, product quality are stable, yields is high, simple and convenient slurry stirring device.
Utility model content
To solve, above-mentioned prior art mixing effect is poor, control accuracy is low, can not ensure viscosity continues consistency, product matter
The problems such as unstable, yields is low, inconvenient for operation is measured, the utility model adopts the following technical solution：
The utility model provides a kind of slurry stirring device for lithium battery coating apparatus, including slurry accumulator, follows
Ring pump, viscosity measurements sensor, signal controller, metering pump and slurry addition tank, the slurry accumulator are arranged on external painting
Cloth equipment side, the inlet connector of the circulating pump expect that conduit is connected with slurry accumulator by pumping, the discharging of the circulating pump
Connector is connected by feed conduit with slurry accumulator, and the viscosity measurements sensor is arranged on pumping material pipe inner wall, described
Metering pump is connected by delivery pipe one end with feed conduit, the other end is connected with slurry addition tank, the signal controller difference
With viscosity measurements sensor, metering pump signal communication.
The beneficial effects of the utility model are：Circulating pump uninterruptedly sends slurry extraction back to and detects viscosity in real time, goes out
Real-time addition slurry can be ensured that the viscosity of slurry continues consistency, mixing effect is good, control essence by existing viscosity change metering pump
Degree is high, easy to operate simple, and obtained product quality is stable, yields is high.
Description of the drawings
Fig. 1 is a kind of structure diagram of embodiment of the utility model.
Specific embodiment
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, a kind of slurry stirring device for lithium battery coating apparatus, including slurry accumulator 1, circulating pump
2nd, viscosity measurements sensor 3, signal controller 4, metering pump 5 and slurry addition tank 6, the slurry accumulator 1 is arranged on external
Coating apparatus side, the inlet connector 21 of the circulating pump 2 expect that conduit 22 is connected with slurry accumulator 1 by pumping, the cycle
The discharging connector 23 of pump 2 is connected by feed conduit 24 with slurry accumulator 1, and the viscosity measurements sensor 3 is arranged on pumping material
On 22 inner wall of conduit, the metering pump 5 is connected by delivery pipe one end with feed conduit 24, the other end and slurry addition tank 6 connect
Logical, the signal controller 4 is respectively with viscosity measurements sensor 3,5 signal communication of metering pump, and during operation, circulating pump starts,
Slurry in slurry accumulator expects that conduit extraction is sent back to again through feed conduit by pumping, realizes internal self-loopa, is also with regard to realizing
Automatic stirring, while viscosity measurements sensor is in real time detected slurry viscosity during material conduit extraction is taken out, viscosity
Detection sensor presets a standard value, and when detection can send a signal to signal controller if beyond standard value, believe
Number controller will convert signal and issue metering pump, and the slurry that metering pump will pump corresponding measurement according to the signal received arrives
In slurry accumulator, it can ensure that stirring abundant, viscosity continues unanimously in this way.
The utility model uninterruptedly sends slurry extraction back to by circulating pump and detects viscosity in real time, viscosity change meter occurs
Real-time addition slurry can be ensured that the viscosity of slurry continues consistency, mixing effect is good, and control accuracy is high, operation side by amount pump
Just simple, obtained product quality stabilization, yields is high.
The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field
The appropriate variation or modification that those of ordinary skill does it all should be regarded as not departing from the patent category of the utility model.
