Technical Field
The invention relates to a magnetic rod, in particular to an arrangement structure of magnetic cores in the magnetic rod.
Background
The iron removal is one of important steps in the production process of the lithium battery, has great influence on the quality and the service life of the lithium battery, and the performance of the lithium battery is directly influenced by the iron removal effect. There is the deironing step many times in the production process of lithium cell, wherein main thick liquids deironing, coiling deironing etc. have, and the deironing in-process material can be vertical motion along bar magnet array direction at lithium electricity coiling deironing, and the iron impurity in the material can be adsorbed by the bar magnet when the bar magnet, but this kind of deironing mode has a defect. The magnetic cores in the existing magnetic rod are arranged in a single row, the adjacent magnetic poles are homopolar, the magnetic poles in the magnetic rod are distributed as shown in figure 1, the magnetic force lines of the magnetic rod are distributed as shown in figure 2, and the width and the length of the magnetic rod in figures 1 and 2 are 25mm and 300 mm. The arrangement mode enables a part of areas of the magnetic rods to have no magnetic force and a part of areas to have weak adsorption capacity, so that iron impurities in part of materials cannot be adsorbed, and the quality of the lithium battery is affected.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a continuous magnetic circuit structure of an iron-removing magnetic rod for a lithium battery, which enables the whole magnetic rod to obtain stable and consistent magnetic field intensity by changing the arrangement mode of magnetic blocks in the magnetic rod and solves the problem of the reduction of the magnetic field intensity of an intermittent section of the magnetic rod caused by the arrangement of an internal magnetic core.
In order to solve the technical problem, the invention is solved by the following technical scheme: the utility model provides a continuous magnetic circuit structure of deironing bar magnet for lithium electricity, is provided with a plurality of magnetic core in the bar magnet, characterized in that, the magnetic core be in the bar magnet in be the matrix pattern and arrange, adjacent from top to bottom the magnetic core is in opposite directions at the same level.
Preferably, in the above technical solution, the magnetic core is a rectangular magnetic block.
Preferably, in the above technical solution, the magnetic rod is rectangular.
Preferably, in the above technical solution, a gap is provided between adjacent magnetic cores.
Preferably, in the above technical solution, a partition is provided between adjacent magnetic cores.

Preferably, in the above technical solution, the number of longitudinally arranged magnetic cores is greater than or equal to the number of transversely arranged magnetic cores.
The magnetic induction lines (magnetic lines) are virtual lines, the magnetic induction lines are closed curves, the magnetic induction lines around the magnet all go out from the N pole to the S pole, and the magnetic induction lines in the magnet are from the S pole to the N pole. For the magnetic rod, small magnetic blocks which are uniformly distributed at intervals and are linearly arranged are arranged in the magnetic rod, and all the small magnetic blocks are opposite in the same step. The repulsion of the same polarity is outward, the magnetic lines of force do not intersect, the same polarity attracts, the magnetic lines of force are communicated, the magnetic induction lines of the arrangement mode come out from the N pole and enter the S pole, the adjacent magnetic fields mutually influence but cannot intersect, and the whole magnetic lines of force present a regularly repeated flat ellipse on the magnetic rod, so that the magnetic field intensity between the S pole and between the N pole and the N pole is weaker, and the magnetic field intensity can be reduced to 0 if the interval distance is not well set. This creates a problem of non-uniform magnetic field strength on the bar magnet, which may allow the bar magnet to miss some of the iron impurities if the material is fed in at a vertical angle along the bar magnet. This application has then solved this kind of problem, and in this application, the magnetic path in the bar magnet is the matrix setting, both the bar magnet from top to bottom and between controlling all can produce magnetism and feel the line, and magnetism feels the line very complicated this moment, between S utmost point and the S utmost point between from top to bottom, magnetism feels the line and receives the interference of controlling the magnetic path between N utmost point and the N utmost point for the magnetic field intensity at here can reach stable state, lets the magnetic field intensity of whole bar magnet very even.
Compared with the prior art, the invention can ensure that the whole magnetic rod can obtain stable and consistent magnetic field intensity by changing the arrangement mode of the magnetic blocks in the magnetic rod, and solves the problem of the magnetic field intensity reduction of the intermittent section of the magnetic rod caused by the arrangement of the internal magnetic cores in the prior art.
