The utility model content
Technical problem to be solved in the utility model provides and a kind ofly can improve de-ironing efficiency and remove iron tramp dry powder deironing device easily.
The utility model is to realize by following technical scheme:
A kind of dry powder deironing device, be provided with magnetic row case, the upper end of this magnetic row case is provided with charging aperture, be provided with discharging opening in magnetic row case lower end, be provided with the plurality of magnetic ferule side by side in this magnetic row case, be provided with metal bar in this magnet sleeve, coiling has coil on this metal bar, one end of this coil is connected with positive source, and the other end of this coil is connected with the negative pole of power supply.
On the said structure basis, wherein:
Be positioned at the same side mutually with a end that positive source is connected on each coil, the other end that is connected with the negative pole of power supply on this coil also is positioned at the same side mutually.
Described magnet sleeve is removably disposed in the magnetic row case.
The outer surface of described magnet sleeve is formed with thread groove.
The charging aperture place of described magnetic row case is provided with the shunting sieve.
Compared to prior art, the beneficial effect of a kind of dry powder deironing device of the utility model is: the metal bar that winding around is installed in the described magnet sleeve, the both positive and negative polarity of this coil switch power, and the outer surface in magnet sleeve is formed with thread groove, the both positive and negative polarity of coil is connected power supply when work, produce magnetic field, make magnet sleeve produce magnetic, and the thread groove on the magnet sleeve can evenly disperse the dry powder of flowing through, and can be adsorbed on iron tramp on the magnet sleeve firmly, end-of-job, deenergization, magnetic is eliminated, magnet sleeve is taken off, adsorbed iron tramp comes off automatically, and the utility model is simple in structure, and it is convenient to improve de-ironing efficiency and remove iron tramp.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
A kind of dry powder deironing device of the utility model, be provided with magnetic row case 1, this magnetic row case 1 outer support 5 that is fixed with, the upper end of this magnetic row case 1 is provided with charging aperture 2, these charging aperture 2 places are provided with shunting sieve 9, lower end at magnetic row case 1 is provided with discharging opening 3, in this magnetic row case 1, be provided with some magnet sleeve of making by stainless steel 4 side by side, this magnet sleeve 4 is horizontally set in the magnetic row case 1 in the present embodiment, and this magnet sleeve 4 is removably disposed in the magnetic row case 1, outer surface in this magnet sleeve 4 is formed with thread groove 7, in every magnet sleeve 4, be inserted with metal bar 6, coiling has coil 8 on the metal bar 6, one termination energize positive pole of this coil 8, the other end of this coil 8 is connected the negative pole of power supply, is positioned at the same side mutually with a end that positive source is connected on each coil 8, also is positioned at the same side mutually with the other end that the negative pole of power supply is connected on this coil 8.
The utility model is connected power supply when work, the metal bar 6 that is wound with coil 8 will produce magnetic field, this magnetic field makes the magnet sleeve 4 that is inserted with metal bar 6 produce magnetic, when dry powder enters magnetic row case 1 inside from charging aperture 2, in process through plurality of magnetic ferule 4, magnetic on the magnet sleeve 4 can be adsorbed the iron tramp in the dry powder, and magnet sleeve 4 outer surfaces are formed with thread groove 7, can increase the contact area of dry powder and magnet sleeve 4 like this, this thread groove 7 can evenly disperse the dry powder of flowing through, and can make iron tramp be adsorbed on firmly on the magnet sleeve 4; When quitting work, deenergization, at this moment eliminate in magnetic field, magnetic on the magnet sleeve 4 is also eliminated, dismounting lower magnet sleeve pipe 4, and the iron tramp that is adsorbed on the magnet sleeve 4 will come off voluntarily because magnetic eliminates, need not metal bar 6 is cleared up, promptly make things convenient for and to improve de-ironing efficiency again.
Embodiment 1: bottom is divided into ten equal portions with a certain amount of lithium cobalt dry powder, get five equal portions and carry out deironing through charging aperture inflow magnetic row case respectively, to be mixed with into anode sizing agent with conductive agent, adhesive, NMP by the dry powder that discharging opening flows out, utilize the ICP method to test iron-holder in this slurry, the iron-holder in the slurry sees Table one and table two.
Comparative example 1: get five other equal portions lithium cobalt dry powder and remove wherein iron tramp by deironing apparatus of the prior art, utilize the ICP method to test iron-holder in this slurry, the iron-holder in the slurry sees Table one and table two.
Table one
Table two
By above-mentioned two tables as can be seen, compared to the deironing apparatus of prior art, the de-ironing efficiency of a kind of dry powder deironing device of the utility model is higher, and de-ferrous effect is better, thereby avoid effectively having improved the performance of lithium ion battery because of the too high self discharge that causes of iron content in the positive active material.
