Description
Technical field
The utility model relates to a kind of lithium-ion-power cell apparatus for removing iron from slurry, is specially adapted to need the lithium battery coating sizing-agent feed system of often dismounting, cleaning, belongs to electrokinetic cell production technical field.
Background technology
Lithium battery slurry is generally uniformly dispersed and is formed by electrode active material, conductive agent, binding agent and dispersant.Slurry need be through operations such as mixing, storage, turnover, conveying, filtration and coatings.Each processing apparatus is many to be manufactured by ferrous metal, slurry mixing device especially, and the cutter group in its working chamber is the manufacture of high hardness alloy stainless steel, although very hard, but after all have wearing and tearing, find that after testing the ultra-fine circulation of slurry disperses after 30 times, iron in slurry is many 5ppm.
In commercial process, the iron in material can affect the self discharge of battery, and namely battery voltage in storage process can decline very fast.Due to the existence of iron, can, in charge and discharge process, on the security performance of battery, also there is larger impact.Li electricity enterprise, in closing the process of slurry, all can avoid the generation of iron tramp conventionally as far as possible, and deironing, prevents the impact of iron on battery performance.
At present, the deironing apparatus of domestic production is mainly two kinds of electromagnet type and permanent magnet types, and most products, when for concrete industry, can not meet industry particular requirement.Especially few to the producer of the higher liquid apparatus for removing iron from slurry research of viscosity.Some producer is designed to all-in-one by filtering function and deferrization functional, and complex structure, once screen pack stops up or damages, will clean by integral demounting, wastes time and energy.Also some adopts a left side to enter right row, and fluid radially passes in and out along magnetic post, and magnetic conduction space is not fully utilized.In addition, due to slurry in transfer pipeline or all kinds of device the time of staying slightly length will produce crystalline solid and precipitate, cause stopping up, this just needs a kind of fast assembling-disassembling, easy cleaned deironing apparatus, meets the requirement of this class operating mode.
Summary of the invention
The purpose of this utility model is to provide a kind of lithium-ion-power cell apparatus for removing iron from slurry, has solved electrokinetic cell slurry and has produced for fast assembling-disassembling and be easy to clean deironing problem.
The purpose of this utility model is to provide a kind of lithium battery apparatus for removing iron from slurry, and technical solution is as follows:
Comprise cylindrical shell, upper cover plate and the combination of magnetic cylinder; Between upper cover plate and shell flange, add silicone rubber seal plate and by lock-screw, be fastenedly connected the magnetic conduction chamber that forms sealing; Upper cover plate is provided with feed hose joint and snap joint; The bottom of cylindrical shell is provided with discharging hose coupling; Magnetic cylinder combination unit is in cylindrical shell, and the combination of magnetic cylinder is fixed between magnetic post pressing plate and magnetic post pressing plate base plate, by several magnetic post pull bars, is strained and fixed.
Described lithium-ion-power cell apparatus for removing iron from slurry, is characterized in that: the combination of magnetic cylinder is to consist of several bar magnets along different radii circumference uniform distribution; Bar magnet two ends stud with positioning boss.
Described lithium-ion-power cell apparatus for removing iron from slurry, is characterized in that: bar magnet adopts high B value rare earth alloy NdFeB material to make device in stainless steel tube.
The utility model slip deironing apparatus is arranged near coating machine feeding groove, by flexible pipe, is connected with coating machine feeding groove, and flexible pipe and deironing apparatus adopt stainless steel snap joint, realize fast assembling-disassembling.
Good effect of the present utility model is: by magnetic cylinder combination unit in magnetic conduction chamber, adopt enterprising lower row's mode, slurry is pressed into magnetic conduction chamber from top entrance, can make full use of the advantage of magnetic column length direction, strengthened that slurry stream crosses to cross magnetic surface long-pending, and then improved deironing precision.Cross that magnetic surface is long-pending is fully used, magnetic field intensity can, according to service condition adjustment, be utilized less aid to realize fast assembling-disassembling and clean.
