[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] This application addresses the problem in the prior art that iron impurities in the battery electrolyte cannot be controlled during the cleaning process. The electrolyte enters the inner support sleeve 3 from the inlet, and the grooves around the inner support sleeve 3 flow to the outlet through the outer sleeve 2 and the gap between the strong magnetic rod 1. At this time, the iron impurities in the circulating electrolyte are adsorbed on the strong magnetic rod 1 to filter the iron impurities, completing the function of the magnetic filter. This operation is safe and reliable, easy to disassemble, and improves the quality of the electrolyte.

[0019] like Figure 1 and Figure 2As shown, in the embodiment of the present invention, the lithium salt pipeline magnetic filter device is connected in series in a flow path, including an outer sleeve 2, a strong magnetic rod 1 is arranged in the outer sleeve 2, and a gap is provided between the strong magnetic rod 1 and the outer sleeve 2 to form a medium channel; the lithium salt pipeline magnetic filter device in the present application can be connected in series in any flow path without specific restrictions. It should be emphasized that the medium flowing in the flow path will pass through the lithium salt pipeline magnetic filter device; and because the lithium salt pipeline magnetic filter device is equipped with a strong magnetic rod 1, when the medium flows through the surface of the strong magnetic rod 1 through the medium channel, the iron impurities in the medium will be adsorbed, thereby achieving the effect of filtering iron impurities; the strong magnetic rod 1 is coaxially arranged in the outer sleeve 2 And form an annular seam; since the medium channel between the strong magnetic rod 1 and the outer sleeve 2 is an annular seam structure, the contact area between the medium and the strong magnetic rod 1 can be increased, and the adsorption surface of the strong magnetic rod 1 can be fully utilized; the interface end of the outer sleeve 2 has an inwardly tapered stepped groove, and an inner support sleeve 3 is installed in the stepped groove. The insertion end of the inner support sleeve 3 is detachably connected to the strong magnetic rod 1, and the inner support sleeve 3 is circumferentially provided with an opening connected to the medium channel; the detachable here refers to an indirect or direct connection, such as a bolt connection, a threaded connection, a clamping connection or an overlap connection, and no excessive restrictions are made here; the inner support sleeve 3 can be used to limit the strong magnetic rod 1, thereby forcing the position of the strong magnetic rod 1 to be coaxially restricted in the outer sleeve 2 To form an annular seam, at the same time, the opening opened on the curved surface of the inner support sleeve 3 can connect the medium to allow the medium to circulate; the interface end of the outer sleeve 2 is rotatably connected to the pipe 6, and the pipe 6 presses the inner support sleeve 3; the pipe 6 is used to apply a pressure to the inner support sleeve 3, forcing the inner support sleeve 3 to always abut the strong magnetic rod 1 to achieve fixation; a boss PTFE pad 5 is provided between the pipe 6 and the inner support sleeve 3, and the inner support sleeve 3 and the pipe 6 are in indirect contact through the boss PTFE pad 5. In the installed state, the pipe 6 squeezes the inner support sleeve 3 and forces the boss PTFE pad 5 to deform; the boss PTFE pad 5 is used to make the inner support sleeve 3 and the pipe 6 in indirect contact, and the two are distributed on both sides of the boss PTFE pad 5. When the pipe 6 applies pressure, it can The inner support sleeve 3 cooperates with the outer sleeve 2 to extrude the boss PTFE pad 5 to deform to fill the gap between the inner support sleeve 3 and the pipe 6 to ensure sealing; a flat PTFE pad 4 is provided between the outer sleeve 2 and the inner support sleeve 3, and the inner support sleeve 3 and the outer sleeve 2 are in indirect contact through the flat PTFE pad 4. In the installed state, the inner support sleeve 3 squeezes the outer sleeve 2 and forces the flat PTFE pad 4 to deform; when using the flat PTFE pad 4, the inner support sleeve 3 and the outer sleeve 2 are in indirect contact, and the two are distributed on both sides of the flat PTFE pad 4. After the inner support sleeve 3 is installed in the outer sleeve 2, when the outer sleeve 2 is compacted, the flat PTFE pad 4 can cooperate with the pressure between the inner support sleeve 3 and the outer sleeve 2 to produce deformation to form a gap between the outer sleeve 2 and the inner support sleeve 3 to ensure sealing.
