Meanwhile, the magnetic field intensity of the outer wall of the sleeve pipe assembly 12 is more than or equal to 10000GS, certainly, the magnetic field intensity of the outer wall of the sleeve pipe assembly 12 can be less than 10000GS, and only the adsorption effect on magnetic impurities is reduced, and magnetism can be removed, in other words, the magnetism of the magnetic rod assembly 11 plays a role in separating the sleeve pipe assembly 12 to adsorb the magnetic impurities in the lithium battery slurry. Specifically, the magnetic field of the magnetic rod assembly 11 acts through the sleeve assembly 12, and the magnetic impurities are adsorbed by the force of the magnetic field. Because the magnetic rod assembly 11 is sleeved in the sleeve assembly 12, the adsorbed magnetic impurities are adsorbed on the sleeve assembly 12.

In the cleaning state, the magnetic rod assembly 11 is removed from the sleeve assembly 12, and the sleeve assembly 12 is free from magnetic field and magnetism, so that the magnetic impurities and a small amount of slurry on the sleeve assembly 12 can be washed clean by the cleaning solution. When the working state is entered, the magnetic rod assembly 11 is put into the sleeve assembly 12 again, and the working state can be entered again. The working state and the cleaning state have different time and space, so that the cleaning frequency of the magnetic rod 112 is improved, and the demagnetizing effect of the slurry is improved.

The magnetic rod assembly 11 is movably connected with the sleeve assembly 12, and the magnetic rod 112 is convenient to disassemble after being magnetically descended or damaged.
The sleeve assembly 12 includes a cavity structure 121 for accommodating the magnetic rod 112, and the cavity structure 121 is adapted to the magnetic rod 112.

In the art, high pressure gate valves, which are positive seal type valves, must apply pressure to the gate plate when the valve is closed to force the sealing face from leaking. When the medium enters the valve body from the lower part of the flashboard, the resistance to be overcome by the operating force is the friction force of the valve rod and the packing and the thrust generated by the pressure of the medium, the force for closing the valve is larger than the force for opening the valve, so the diameter of the valve rod is larger, otherwise the failure of the valve rod bending can occur. When the high-pressure gate valve is opened, the opening height of the gate plate is 25% -30% of the nominal diameter, the flow reaches the maximum, and the valve reaches the full-open position. Therefore, the fully open position of the gate valve is determined by the stroke of the gate plate.
In the art, a bar magnet consists of an inner core and an outer cladding, and the core consists of a cylindrical magnet block and a magnetically permeable iron sheet. A good magnetic bar should be made with magnetic induction lines distributed evenly in space, the point distribution of the maximum magnetic induction intensity is filled with the whole magnetic bar as much as possible, and the surface magnetic induction intensity of the magnetic bar is in direct proportion to the size of the smallest particle capable of being adsorbed. The working environment of the magnetic rod determines that the magnetic rod has certain corrosion resistance and high temperature resistance and does not contain substances harmful to the environment, the use effect is ensured, and the pollution to materials and the environment is avoided. The magnetic bar is applied to different occasions, so that the selected magnetic bar is different in thickness, and in some occasions, stronger magnetic induction intensity is needed, and different magnetic induction intensity is obtained by adopting the magnetic conductive sheets with different thicknesses. When the magnetic rod is manufactured, the surface magnetic induction intensity of more than 10000 gauss on the conventional magnetic rod with the diameter of 1 inch needs neodymium iron boron magnetic steel with the model of more than N40, the high-temperature resistant magnetic rod generally selects samarium cobalt magnetic steel at the temperature of more than 150 ℃, but the large-diameter magnetic rod does not select samarium cobalt, the price of the samarium cobalt is very high after all, and the price of one magnetic rod with the diameter of 50 x 500 reaches ten thousand RMB. In the fields of batteries, pharmacy and the like, fine iron impurities can also cause great influence, so that a magnetic rod of about 10000 gauss needs to be selected. Other fields may be selected a little lower; when the magnetic bar is in contact with fluid in use, the magnetic energy inside the magnetic bar is partially and irreversibly lost, the loss exceeds the initial strength by 30 percent or the iron sheet on the surface is coated, and when a stainless steel pipe is worn and broken, the magnetic bar needs to be replaced, the magnetic bar leaking out of the magnet cannot continue to work, the magnet is generally brittle, the surface is coated with oil, and the environmental pollution is high.
