在锂离子电池生产过程中，需要制作正负极浆料，然后将浆料烘干粘附在对应的正负极片上。在制作这样的浆料时，由于浆料本身的构成材料以及在制作中的污染等影响，在浆料中存在铁质材料，如果这些铁质材料粘附在正负极片上，则这样制作出的锂离子电池的性能降低，因此通常在输送这样的浆料的过程中，使用除铁器除去浆料中的铁质材料。In the production process of lithium-ion batteries, it is necessary to make positive and negative electrode slurry, and then dry the slurry to adhere to the corresponding positive and negative electrode sheets. When making such a slurry, due to the influence of the constituent materials of the slurry itself and the pollution in the production, there are iron materials in the slurry. If these iron materials adhere to the positive and negative electrodes, the The performance of the lithium-ion battery is reduced, so in the process of conveying such a slurry, an iron remover is usually used to remove the iron material in the slurry.
但是，在现有技术中，浆料输送过程中所用的除铁器主要由外壳和外壳内磁棒构成，磁场强度小，仅能达到4000GS左右，强度低，无法满足除铁要求，只能通过串联多个除铁器提高除铁能力，但是这样加大了浆料输送过程的流阻和增加了清洁数量。However, in the prior art, the iron remover used in the slurry transportation process is mainly composed of the shell and the magnetic rod inside the shell, the magnetic field strength is small, only about 4000GS, and the strength is low, which cannot meet the iron removal requirements, and can only be connected in series Multiple iron removers improve the iron removal capacity, but this increases the flow resistance of the slurry conveying process and increases the number of cleaning.

Therefore, it is possible to prevent damage to the electromagnetic coil, and to prevent accidental touches by external objects or operators, thereby increasing safety.
另外，根据技术方案3的锂离子电池浆料的除铁器，在磁棒外侧外套有磁棒套筒。线圈断电后铁磁性物质仍会被吸附在磁棒套筒表面。磁棒不会对不锈钢材质的磁棒套筒产生磁化，将磁棒部分取出后，可以便捷的去除附着在磁棒套筒表面的铁磁性物质。而且将磁棒和浆料隔离不会产生二次污染。In addition, according to the iron remover for lithium ion battery slurry according to the technical solution 3, a magnetic rod sleeve is covered outside the magnetic rod. After the coil is powered off, the ferromagnetic substance will still be adsorbed on the surface of the magnetic bar sleeve. The magnetic rod will not magnetize the stainless steel magnetic rod sleeve. After the magnetic rod is partially taken out, the ferromagnetic substance attached to the surface of the magnetic rod sleeve can be easily removed. Moreover, the separation of the magnetic rod and the slurry will not cause secondary pollution.

具体实施方式Detailed ways
下面，基于附图说明作为本实用新型的一个例子的锂离子电池浆料的除铁器。Next, the iron remover of the lithium ion battery slurry which is an example of this invention is demonstrated based on drawing.
图1是表示本实用新型的锂离子电池浆料的除铁器的剖视示意图。Fig. 1 is a schematic cross-sectional view showing an iron remover for lithium ion battery slurry according to the present invention.
如图1所示，本实用新型的锂离子电池浆料的除铁器具有内部形成有空腔的除铁器壳体10，在除铁器壳体10的顶壁11上设置有向空腔内延伸的磁棒20，在顶壁11的不同于磁棒所处的位置上，形成有进料口12和出料口13。As shown in Figure 1, the iron remover for lithium-ion battery slurry of the present invention has an iron remover housing 10 with a cavity formed inside, and a top wall 11 extending into the cavity is provided on the top wall 11 of the iron remover housing 10. The magnetic bar 20 is formed with a feeding opening 12 and a feeding opening 13 on the top wall 11 at a position different from that of the magnetic bar.
在除铁器壳体10外，包围除铁器壳体10形成有与电源连接的电磁线圈30，电磁线圈30的磁场方向与磁棒20的磁场方向一致。Outside the iron remover housing 10 , an electromagnetic coil 30 connected to a power source is formed surrounding the iron remover housing 10 , and the magnetic field direction of the electromagnetic coil 30 is consistent with the magnetic field direction of the magnetic bar 20 .
这样，能够通过对电磁线圈通电形成辅助磁场，通过辅助磁场增强除铁器的磁场强度而形成强磁场，由此能够有效地除去浆料中的铁磁性物质，最大限度的减少流到后续的铁磁性物质。另外，可以通过调节电磁线圈的通电电流可以改变电磁线圈的磁场强度，从而能够对应于对浆料的要求的不同，形成不同强度的磁场，满足各种要求。另外，浆料流经时会带走线圈产生的热量不会过热。In this way, the auxiliary magnetic field can be formed by energizing the electromagnetic coil, and the magnetic field strength of the iron remover can be enhanced by the auxiliary magnetic field to form a strong magnetic field, so that the ferromagnetic substances in the slurry can be effectively removed, and the subsequent ferromagnetic substances can be minimized. substance. In addition, the magnetic field strength of the electromagnetic coil can be changed by adjusting the energizing current of the electromagnetic coil, so that it can form magnetic fields of different strengths to meet various requirements in response to different requirements for the slurry. In addition, when the slurry flows through, it will take away the heat generated by the coil without overheating.
具体地说，永磁铁磁棒位于除铁器腔体中部，电磁线圈封闭于除铁器腔体与外罩中，电磁线圈封通过线缆连接24V直流电源。磁棒的排列方式为圆周排列方式，磁棒安装后的磁场保持方向一致。同时电磁线圈通电产生磁场并使之和磁棒产生的磁场方向一致，通过调节线圈的通电电流可以改变磁场强度。另浆料经由进料口流入，经由出料口流出，浆料流经腔体时，其中的杂质会被吸附到磁棒表面，异常断电时仍能保证杂质被吸附在磁棒上。浆料流经时，会带走线圈产生的部分热量，降低除铁器的热量。Specifically, the permanent magnet bar is located in the middle of the iron remover cavity, the electromagnetic coil is enclosed in the iron remover cavity and the outer cover, and the electromagnetic coil is connected to a 24V DC power supply through a cable. The arrangement of the magnetic rods is a circular arrangement, and the magnetic field after the magnetic rods are installed keeps the same direction. At the same time, the electromagnetic coil is energized to generate a magnetic field and make it consistent with the direction of the magnetic field generated by the magnetic bar. The magnetic field strength can be changed by adjusting the current of the coil. In addition, the slurry flows in through the feed port and flows out through the discharge port. When the slurry flows through the cavity, the impurities in it will be adsorbed to the surface of the magnetic rod. When the power is abnormally cut off, the impurities can still be adsorbed on the magnetic rod. When the slurry flows through, it will take away part of the heat generated by the coil and reduce the heat of the iron remover.
另外，电磁线圈30可以封闭在除铁器壳体10与位于除铁器壳体外侧的罩体40之间。从而能够防止对电磁线圈产生伤害，也防止外界的物体或操作人员误碰，增加了安全性。In addition, the electromagnetic coil 30 may be enclosed between the shell 10 of the iron remover and the cover 40 located outside the shell of the iron remover. Therefore, it is possible to prevent damage to the electromagnetic coil, and to prevent accidental touches by external objects or operators, thereby increasing safety.
另外，在磁棒20外侧可以外套有磁棒套筒50。线圈断电后铁磁性物质仍会被吸附在磁棒套筒表面。磁棒不会对不锈钢材质的磁棒套筒产生磁化，将磁棒部分取出后，可以便捷的去除附着在磁棒套筒表面的铁磁性物质。而且将磁棒和浆料隔离不会产生二次污染。In addition, a magnetic rod sleeve 50 may be placed outside the magnetic rod 20 . After the coil is powered off, the ferromagnetic substance will still be adsorbed on the surface of the magnetic bar sleeve. The magnetic rod will not magnetize the stainless steel magnetic rod sleeve. After the magnetic rod is partially taken out, the ferromagnetic substance attached to the surface of the magnetic rod sleeve can be easily removed. Moreover, the separation of the magnetic rod and the slurry will not cause secondary pollution.
