Description
Technical field
It the utility model is related to a kind of tramp iron separator, and in particular to a kind of carbon nano tube paste tramp iron separator.
Background technology
CNT is in recent years emerging high-end conductive material, and its general diameter reaches 10 in 5~60 rans, length
~20 microns, because its unique one-dimensional nano structure possesses excellent mechanics, electricity, calorifics, optics and reactivity worth, claimed
To be " coal " in nano material.In lithium ion battery, it can not only serve as the effect of " wire " in conductive network,
It also has electric double layer effect simultaneously, plays the high-rate characteristics of ultracapacitor, its good heat conductivility also helps electricity
The radiating during discharge and recharge of pond, the polarization of battery is reduced, improve the high temperature performance of battery, extend the life-span of battery.
Ferromagnetic metal impurity is easily produced and separates out in carbon nano tube paste preparation, course of conveying.Into lithium ion
Inside battery micro-short circuit is easily caused after battery, the possibility that self-discharge of battery becomes big, serious triggers security incident.Therefore, these
Material demand removes in time, to strengthen the quality of production of battery and security performance.
But in the prior art, tramp iron separator used is mainly by bar magnet structure in shell and shell in slurry course of conveying
Be only capable of reaching 4000GS or so into, magnetic field intensity, low intensity can not meet iron removaling requirement, can only by connect multiple tramp iron separators with
De-ferrous effect is obtained, but so increases the flow resistance and cleaning difficulty of slurry course of conveying.
Therefore, can be in carbon nano tube paste course of conveying, in time, efficiently there is an urgent need to develop a kind of technology
Magnetic metal material present in slurry is removed, reduces be flowed into magnetic gold possessed by lithium-ion electric pool process to greatest extent
Belong to content, it is ensured that the quality of production and security performance of the lithium ion battery finally produced.
Utility model content
The purpose of this utility model is to provide a kind of tramp iron separator of carbon nano tube paste, in carbon nano tube paste preparation process
In, ferromagnetic material present in slurry is fast and efficiently removed, reduction, which is flowed into further battery slurry, as far as possible is had
Ferromagnetic material content, it is ensured that the quality of production and security performance of the battery finally produced, improve production yields, have weight
Big production practices meaning.
A kind of carbon nano tube paste tramp iron separator described in the utility model, including cylinder, cylinder top opening, cylinder top
Cover plate is set, cover plate bottom fixed setting bar magnet insert port, bar magnet insert port is interior to be provided with bar magnet, and bar magnet sleeve is cased with outside bar magnet,
Bar magnet sleeve is fixedly connected with bar magnet by pipe clamp；Sealing ring is set between cover plate and cylinder.
Charging aperture is set on the outer wall bottom of cylinder side, and opposite side outer wall top sets discharging opening.
Cover plate is circle.
Cover plate upper end is provided with U-shaped handle.
The magnetic field intensity 10000-12000GS of the bar magnet.
The bar magnet insert port quantity is 7-20.
The top of the circular cover is circumferentially spaced to be provided with multiple bar magnet insert ports, and bar magnet is put into sleeve, magnetic
Rod sleeve is connected with insert port by stainless steel pipe clamp.
Sealing ring is set between the cylinder and circular cover, and the sealing ring material is silica gel or polytetrafluoroethylene (PTFE).
The utility model is used as the tramp iron separator of lithium ion battery conductive agent carbon nano tube paste.
Compared with prior art, the utility model has the advantages that：
The tramp iron separator of carbon nano tube paste described in the utility model is quick, high in carbon nano tube paste preparation process
Effect ground removes ferromagnetic material present in slurry, reduces being flowed into ferromagnetism thing possessed by further battery slurry as far as possible
Matter content, it is ensured that the quality of production and security performance of the battery finally produced, improve production yields, have great production real
Trample meaning.
Because the slurry inlet of the utility model design is less than slurry outlet, slurry can be full of whole chamber to greatest extent
Body, the time of contact of slurry and bar magnet is extended, the iron removaling time can be reduced, improve production efficiency.

Specific implementation method
In order to understand the utility model, the utility model is made with reference to the accompanying drawings and examples further detailed
Explanation.
Embodiment 1
Such as Fig. 1, the utility model carbon nano tube paste tramp iron separator, including cylinder 1, the top end opening of cylinder 1, the top of cylinder 1
Cover plate 3 is set, and the bottom of cover plate 3 fixed setting bar magnet insert port, bar magnet insert port is interior to be provided with bar magnet 7, and bar magnet set is cased with outside bar magnet 7
Cylinder 6, bar magnet sleeve 6 is fixedly connected with bar magnet 7 by pipe clamp 4；Sealing ring 5 is set between cover plate 3 and cylinder 1.
Charging aperture 8 is set on the outer wall bottom of the side of cylinder 1, and opposite side outer wall top sets discharging opening 9.
Cover plate 3 is circle.
The upper end of cover plate 3 is provided with U-shaped handle 2.
