Description
Technical field
The utility model relates to a kind of defoaming device, especially relates to a kind of lithium battery slurry defoaming device.
Background technology
In the homogenate operation of lithium ion battery manufacture process; Must and remove the bubble that in the preparation process, is produced to prepared slurry stirring, otherwise slurry can cause being coated with the pole piece surface and have bubble in coating process; Cause crawling, influence the performance of pole piece.
At present, the main mode of slurry deaeration is vacuum defoamation, promptly under vacuum condition; Slurry through in the paddle stirred vessel is realized deaeration, for example, and Chinese patent Granted publication number: CN201203730Y; Granted publication day: disclosed a kind of deaeration machine on March 4th, 2009, comprised the cabin body with sealed transmission structure; On the body of said cabin a sealed driving mechanism is housed, it is characterized in that: said sealed driving mechanism comprises pair of magnetic interlock dish, is loaded on respectively in the inside and outside, cabin.Its weak point is that this deaeration machine is complex structure not only, and defoaming method is comparatively single; Deaeration is insufficient, and for the higher slurry of viscosity, bubble wherein difficulty is deviate from addition; Need to strengthen vacuum, and prolong mixing time and just can reach required deaeration effect, but so not only can reduce production efficiency; Volatile component runs off in a large number in the slurry but also can cause, and causes paste composition to change, and influences the performance of slurry.
The utility model content
The utility model is that deaeration is insufficient, and is not suitable for the deficiency of highly viscous slurry deaeration for the defoaming method that overcomes prior art is single; A kind of each viscosity slurry deaeration that is applicable to is provided; And deaeration is effective, and deaeration speed is fast, the slurry defoaming device that production efficiency is high.
To achieve these goals, the utility model adopts following technical scheme:
A kind of lithium battery slurry defoaming device; Comprise tank body and be fixed on the driving mechanism of tank body end face; Said tank body end face also is connected with feed pipe and vacuum extractor, and the tank body bottom surface is connected with discharge nozzle, is provided with the barrel that gets rid of that links to each other with driving mechanism in the said tank body; The said barrel that gets rid of barrel is provided with some mesh, and the mouth of pipe of said feed pipe passes the tank body end face and is positioned at and gets rid of the barrel top.The barrel that gets rid of in the utility model drives through driving mechanism, when slurry proceed to from feed pipe get rid of the barrel after because action of centrifugal force; Slurry can throw away from the mesh on getting rid of the barrel barrel and attached on the inner tank wall, because there are density contrast in slurry and bubble, under action of centrifugal force; The slurry that density is bigger throws away from mesh earlier, thus the less bubble of the density that stays, and the less bubble of these density can be because of the vacuum swelling fracture; Detached at last, accomplished the process of deaeration for the first time this moment, when slurry is got rid of to inner tank wall; And under the gravity effect along inner tank wall when dirty gradually, slurry can form thin film on inner tank wall, because the film that forms is very thin; Therefore the bubble scrapping off film surface in the film is very near, under vacuum action, and the rapid swelling fracture of meeting; Thereby reach the effect of rapidly defoaming, accomplish the process of deaeration for the second time this moment, the slurry after the deaeration converges to and just can be transported to dispense tip through discharge nozzle after the tank base and be coated with; The utility model combines the centrifugal material that gets rid of with the vacuum principle, and through twice deaeration improving deaeration effect and deaeration speed greatly, thereby enhance productivity; In addition, the utility model is simple in structure, and is easy to operate.
As preferably, said driving mechanism comprises motor, said motor be fixed on the tank body end face and through rotating shaft with get rid of barrel and link to each other.Motor-driven rotatable shaft is rotated, and gets rid of the barrel rotation thereby drive, and rotating speed of motor is adjustable, can select corresponding rotating speeds according to the slurry of different viscosities, thereby makes the utility model be applicable to each viscosity slurry deaeration.
As preferably, said vacuum extractor comprises vavuum pump, and said vavuum pump links to each other with the tank body end face through vacuum tube.Vacuum pump structure is simple, and is easy to use, and vacuumizes effective.
As preferably, said tank body is formed by connecting with the lower tank that is cylindrical shape being down round table-like upper tank body.It is round table-like that upper tank body is, and can effectively prolong the flowing time of slurry on inner tank wall, and bubble can fully be deviate from, thereby improve the deaeration effect, and lower tank is cylindrical shape, to hold more slurry.
As preferably, the following base angle of said upper tank body shaft section is 110 ~ 130 °.The following base angle of upper tank body shaft section is too small, and then the flowing time of slurry on inner tank wall is shorter, is unfavorable for that bubble deviates from fully; The following base angle of upper tank body shaft section is excessive, and then slurry formed film thickness on inner tank wall is thicker, and the flowing time of slurry is also longer; Even can not flow, when influencing the deaeration effect, reduce production efficiency, the following base angle of upper tank body shaft section is in 110 ~ 130 ° scope; The deaeration effect can be guaranteed, production efficiency can be guaranteed again.
Therefore, the utlity model has following beneficial effect:
(1) deaeration is effective, and deaeration speed is fast, can enhance productivity greatly;
(2) be applicable to each viscosity slurry deaeration;
(3) simple in structure, easy to operate.
