Description

Fluid deironing device

Technical Field

The utility model relates to a magnetic separation technology, in particular to a fluid iron removal technology.

Background

In order to achieve a high iron removal effect by removing iron from an existing fluid, such as ceramic slurry or dry powder air-fed ceramic, a magnetic medium iron removal method is generally adopted, that is, a soft magnetic medium component is arranged in a fluid channel, the soft magnetic medium component is either a plurality of soft magnetic rod groups arranged in parallel or soft magnetic steel bristles, a magnetic field mechanism is arranged outside the fluid channel, for example, permanent magnets or electromagnetic devices with opposite south poles and north poles are arranged on two sides of the fluid channel corresponding to the soft magnetic medium component so as to form a magnetic field acting on the soft magnetic medium component, and the soft magnetic medium component is magnetized under the action of the magnetic field, so that a magnetic field is formed between adjacent soft magnetic rods or adjacent steel bristles forming the soft magnetic medium component, so that ferromagnetic substances in a fluid flowing between the adjacent soft magnetic rods or the adjacent steel bristles are absorbed by the magnetic force of the soft magnetic rods or the steel bristles, and the magnetic force for absorbing the magnetic force is obtained by the physical shape of the soft magnetic medium and the magnetic medium The magnetic attraction force is stronger because the magnetic force lines first travel along the conductor (e.g., soft magnetic medium) and then travel along the closest path after leaving the conductor, and when the magnetic force lines travel from the protrusions, the magnetic force lines are concentrated on the protrusions and are concentrated on the sharp portions of the protrusions, so that the magnetic force is stronger, and the closer the distance between the adjacent soft magnetic media, the range of the magnetic force action is more concentrated in the space between the adjacent soft magnetic media and is less dissipated to other positions, thereby allowing the ferromagnetic substance flowing through the space between the adjacent soft magnetic media to be more easily absorbed. However, the sharp protrusions have a small action surface and a small amount of ferromagnetic material is absorbed, and therefore, a magnetic rod having a plurality of protrusions on a surface thereof is designed, or a soft magnetic steel wool is used to balance the magnetic attraction force with the magnetic action surface, and at the same time, a small magnetic force is compensated by reducing a distance between adjacent soft magnetic media, but the space between the adjacent soft magnetic media is easily blocked by the ferromagnetic material due to the reduction of the distance, which adversely affects the iron removal effect, and therefore, a technology disclosed in patent 201310278903.1 is designed to divide a plurality of thin strips having protrusions (with a triangular cross section) on a surface thereof into a plurality of layers, and the distance between the thin strips of each layer is gradually reduced in a fluid flow direction, and although the soft magnetic material having a large distance absorbs the ferromagnetic material and the soft magnetic material having a small distance absorbs the weak magnetic ferromagnetic material by means of layering, in order to reach and to remove ferromagnetic substance effectively, simultaneously, delay the space between soft magnetic medium again and be blockked up by ferromagnetic substance, in order to promote deironing efficiency, however, because in the ferromagnetic substance that contains in the fluid, ferromagnetic substance's the proportion of taking up is great, though, the cross-section is the magnetic attraction of triangle-shaped thin strip thing strong, but, because the area of magnetism is little, can not satisfy the requirement of absorbing ferromagnetic substance in a large number, lead to some ferromagnetic substance to get into in the little soft magnetic medium layer of interval of last layer, like this, appear forming the jam in the short time equally and influence deironing efficiency's problem. Patent application 201310465592.X discloses a technology for solving the problem that ferromagnetic substances block the space between soft magnetic media, which solves the problem that the blocked ferromagnetic substances are not easily cleaned because the ferromagnetic substances are firmly adsorbed on the soft magnetic media due to residual magnetism of the blocked ferromagnetic substances, but does not provide a technology for solving the problem that the ferromagnetic substances are easily and rapidly blocked due to small spacing and large magnetic attraction of the soft magnetic media.

Compared with the prior art, the utility model, have and to clear away ferromagnetic substance in the fluid effectively, simultaneously, the clearance between the soft magnetic medium in the magnetic field is difficult to again rapidly by the ferromagnetic substance jam that absorbs, advantage that the deironing is efficient.
