Description
Technical field
The utility model relates to a kind of battery electrode that can be used for spraying, and especially sprays the novel slit shower nozzle and the flush coater head thereof of GND.
Background technology
The electrode of battery generally applies one deck slurry and realizes on base material, if apply be anode slurry then be the anode sheet material, if apply the cathode size that is then be negative electrode plate.On base material, apply the way of slurry now, adopt the clearance-type coating machine mostly, the head of this coating machine mainly comprises the edge of a knife; Drive roll, back flow roll, hopper; Back flow roll carries out the gap contact with respect to drive roll, thereby the slurry on the drive roll is transferred on the base material, because slurry at first will be transferred on the drive roll from hopper; Regulate the thickness of slurry again through the last edge of a knife; And transfer to again on the base material on the back flow roll, this coating machine slurry makes the thickness of last slurry on base material be difficult to control through repeatedly shifting.In recent years, People more and more hopes to have a kind of new technology to replace the technology of gap coating, makes that the coating of slurry on base material is more even.Therefore; The slit spraying technology begins to be applied in the electrode coating of battery, and at present, the head of the jet printing type coating machine of the electrode of battery industry coating is the coating machine head improvement from the enamel powder; The anode less for pulp particle applies; Effect is all right, and still, just there are some problems in the negative pole bigger to particle (about 20 μ m); The head of this jet printing type coating machine comprises slit shower nozzle 100, slurry supply pump 110, slurry discharging pump 120, narrow slit type nozzle 130, drive roll 140 and the base material 150 that rotates with drive roll; Said slit shower nozzle 100 is horizontally disposed with, the narrow slit type nozzle 130 of slit shower nozzle 100 and said base material 150 adjacency (referring to Fig. 9 and Figure 10), slurry supply pump 110 and the slurry discharging pump 120 general screw pumps that adopt.During use, open slurry supply pump 110 and slurry discharging pump 120, adjustment slurry supply pump 110 and slurry discharging pump 120 pressure reduction; When the input pressure of slurry supply pump 110 during greater than the output pressure of slurry discharging pump 120, just have slurry from narrow slit type nozzle 130 ejections, on base material, form one deck electrode 160; After electrode 160 reaches preset distance, adjust slurry supply pump 110 and slurry discharging pump 120 pressure reduction again, make slurry supply pump 110 and slurry discharging pump 120 pressure reduction be equal to or less than zero; At this moment; Narrow slit type nozzle 130 stops the spray material, and base material continues to move ahead, and forms gap 170.This flush coater is the design according to product; Change slurry supply pump 110 through PLC by preset program and realize the coating of slurry on base material 150 with slurry discharging pump 120 pressure reduction; As everyone knows; The stiction of the liquid slurry that viscosity is higher is greater than flowage friction power; If be set to equal to overcome the size of flowage friction power at coating initial stage slurry supply pump 110 and slurry discharging pump 120 pressure reduction, certainly will, electrode will lift one's head thin phenomenon (thickness of electrode does not reach design thickness) like this when beginning to be coated with, and this is unallowed.In order to overcome this problem, just slurry supply pump 110 and slurry discharging pump 120 pressure reduction are set to equal to overcome the size (seeing Figure 11) of stiction, coating initial time TS in programming; Recall to again and equal to overcome flowage friction power size; The even cloth time T M of coating is made as zero with slurry supply pump 110 and slurry discharging pump 120 pressure reduction at last again, and operation stops spray material time T P; Form gap 170, accomplish the coating of an electrode; Then, the coating that goes round and begins again so again forms several electrodes.
There are two main problems in the flush coater of this structure, and the one, it is thick to start, and the 2nd, gap 170 instabilities.Starting thick is because at spraying initial time TS; In order to overcome slurry at narrow slit type nozzle 130 stiction; And the pressure reduction of slurry supply pump 110 that adopts and slurry discharging pump 120 is greater than the pressure reduction that overcomes flowage friction power; Thereby cause thickness of electrode in initial time TS greater than designing requirement, be called thick head in the industry; The 2nd, the gap is unstable; The gap shakiness is because when the pressure reduction of adjustment slurry supply pump 110 and slurry discharging pump 120; Slurry supply pump 110 all has a response speed problem with slurry discharging pump 120 and slurry flowing in narrow slit type nozzle 130; At present, existing flush coater is unstable in the response speed that slurry supply pump 110, slurry discharging pump 120 and slurry flow in narrow slit type nozzle 130, thus during the gap width that causes wide advance narrow; The gap is very unstable, causes a lot of troubles to later process.In addition; Also there is a peripheral issue in this flush coater, is exactly on electrode, to form striped easily, and the narrow slit type nozzle 130 of this flush coater can only horizontal arrangement; Service time is long slightly; Particle in the viscosity slurry adheres to the local obstruction of the formation of uniting in the exit 131 of narrow slit type nozzle 130, thereby is forming uncoated striped with the corresponding electrode of blocking portion under the gravity effect.Therefore, this situation appears and after, then need shut down and clean narrow slit type nozzle 130, thereby cause work discontinuous, whole production line is shut down, and loses very greatly, has improved the manufacturing cost of electrode greatly.
