Problems solved by technology

The ferromagnetic material located in the dead corner is not easy to clean out by using the water washing cleaning method; the centrifugal cleaning method, although the effect of cleaning the ferromagnetic material on the soft magnetic medium is ideal, but it is limited by the characteristics of the force line direction of the permanent magnet itself. Limitation, the physical form of the so

Embodiment Construction

[0015] Now in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0016] As shown in the figure, the electromagnetic iron removal method of the present invention is realized in this way. A soft magnetic medium component with rotating power is arranged in the cylindrical channel surrounding the electromagnetic coil on the four sides. The soft magnetic medium component includes Layers of mesh-shaped soft magnets or soft magnetic steel hair balls that are stacked and separated from each other, when removing ferromagnetic substances in the fluid, energize the electromagnetic coil to make the magnetic field lines pass through the channel along the axis of the cylindrical channel, so that The soft magnetic medium component generates a high-gradient induced magnetic field, and then the fluid is introduced into the cylindrical channel, so that the fluid passes through several layers of reticular soft magnets or soft magne...

Abstract

The invention provides an electromagnetic iron-removing method and device. The device comprises a frame, a cylindrical fluid passage which is vertically arranged on the frame, electromagnetic coils and a soft magnetic medium member with a rotary power unit, wherein, the electromagnetic coils are wound on the external side face of the fluid passage; the soft magnetic medium member is arranged in the cylindrical fluid passage and comprises a plurality of layers of stacked mesh soft magnets or soft magnet steel wool balls which are alternately spaced; the rotary power unit is arranged on the frame; the entrance on the lower end of the cylindrical fluid passage is equipped with a fluid lead-in channel and a ferromagnetic substance discharge port with a valve; the upper end of the cylindrical fluid passage is equipped with a fluid discharge port; and the cylindrical fluid passage is made from a nonmagnetic material. Compared with the prior art, the electromagnetic iron-removing method and device have the advantages that by adopting a soft magnetic medium in an ideal physical form which can generate a high gradient magnetic field, the iron-removal effect for a ferromagnetic substance is ensured; and meanwhile a centrifugal cleaning mode is adopted, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a magnetic separation technology, in particular to a technology for magnetically separating ferromagnetic substances in fluids. Background technique [0002] There are generally two types of existing technologies for magnetically removing ferromagnetic substances in fluids, one is electromagnetic high-gradient magnetic field technology, and the other is permanent magnetic high-gradient magnetic field technology. No matter which method is used, it is necessary to set up a high-gradient magnetic field in the magnetic field. The soft magnetic medium of the magnetic field absorbs the ferromagnetic substance in the flowing fluid through the magnetic force generated by the induced magnetic field on the soft magnetic medium, and then, when the ferromagnetic substance adsorbed on the soft magnetic medium reaches a certain level, through a special The cleaning method cleans the ferromagnetic substances on the soft magnetic medium so th...
