Abstract

The utility model discloses a magnetic force separator which is used for attracting, separating and removing the ferromagnetic impurity in material, such as liquid, slurry, fine material, etc. A multipolar magnetic circuit component with strong magnetic attracting force which is composed of permanent magnet discs and magnetic conductor discs which are arranged by a stagger mode is arranged in a cylinder which is provided with a base and is composed of non magnetic material to form the permanent magnet magnetic force separator. The component can freely slide along the axial direction in the cylinder and is provided with a plastic handle. The rod-shaped magnetic force separator with the structure is provided with a plurality of magnet poles whose magnetic attracting force is strong. Therefore, the high quality and the high efficient for removing the ferromagnetic impurity in material can be ensured. The utility model has the advantages of convenient operation, simple and available structure.

Description

Magnetic force separator

The utility model relates to a kind of magnetic separtor, is mainly used in the materials such as various fluids, slurry and powder, separates after wherein ferromagnetism impurity attracts by hand-held and removes, and reaches a kind of magnetic separtor of purification.

Usually ferromagnetism impurity in the materials such as fluid, slurry and powder such as iron filings are employing screenings, hand picking, and traditional methods such as different precipitations of proportion or pneumatic separation are separated removal.These method production efficiencys are low, and primitive labor intensity is big.Also have several permanent magnets are inserted in the material, manually attract ferromagnetism impurity, separate from material then and remove.This method is because its permanent magnet is in open-circuit condition, magnetic attraction is little, select the rate height so leak, particularly volume is big is easy to Lou choosing with very tiny ferromagnetic particle, and the impurity on this permanent magnet attracts is when separating with magnet, because the attraction of magnet is difficult to separately operate very inconvenient.This all can cause material to purify inefficiency, the shortcoming that quality is still needed and improved.

The purpose of this utility model is intended to overcome above-mentioned prior art leakage and selects the rate height, the deficiency of inconvenient operation, provide a kind of magnetic attraction strong, convenient durable, the hand-held magneto magnetic separtor that production efficiency is high, this magnetic separtor is inserted the ferromagnetic impurity of attraction in the material, and impurity comes off automatically and removes from material then.

The purpose of this utility model can reach by following measure.A material be no magnetic material and seal having in the tube of garden, the end of an end with no magnetic material, pack into by permanent magnet garden sheet (or claim garden post) and magnetic conductor garden sheet (or claiming garden post) the axial magnetic circuit assembly of forming alternately along the garden sheet, this assembly must satisfy with the end of the contacted two permanent magnet garden sheets of each piece magnetic conductor garden sheet when arranging identical polarity, the total length of this assembly is changeable as required, but total length must be less than half of no magnetic material garden tube length degree, and this assembly is after being incorporated with garden, end tube, with should leave around the tube of garden can guarantee this assembly in the tube of garden along the gap that the garden tube axially is free to slide, at last insert the plastic handle that also its end and tube end, garden are fixed as one at the openend of no magnetic material garden tube.

Because permanent magnet garden sheet and magnetic conductor garden sheet are along the magnetic circuit assembly of axially forming alternately of garden sheet, there is identical polarity the end that must satisfy the two block permanent magnet garden sheets adjacent with each piece magnetic conductor garden sheet when arranging, each piece magnetic conductor garden sheet has all been assembled the magnetic line of force of adjacent two block permanent magnet identical polars like this, become the new magnetic pole of this magnetic circuit assembly of a magnetic force multiplication, have the stronger magnetic circuit assembly of multipole magnetic force thereby just formed one.Each new magnetic pole all has very strong attraction to ferromagnetism impurity in the material.In addition because the length of this magnetic circuit assembly must be less than half of no magnetic garden tube length degree, and can in the tube of garden, be free to slide, just can guarantee after having attracted ferromagnetism impurity, this magnetic separtor is inverted, because the gravity of its magnetic circuit assembly, the magnetic circuit assembly slides into the other end of no magnetic garden tube very soon, and this moment, ferromagnetism impurity can come off from no magnetic garden drum outer wall automatically, reached the purpose of removing impurity automatically.

Describe in detail further below in conjunction with the utility model accompanying drawing.

Fig. 1. be the vertical section schematic diagram of magnetic separtor.

As Fig. 1. shown in the utility model be having in garden, the end tube ［ 1 ］ that magnetism-free stainless steel constitutes, pack into and prolonging the axial magnetic circuit assembly of forming alternately ［ 4 ］ of garden sheet by Rare-Earth Cobalt or rare earth iron permanent magnet garden sheet ［ 2 ］ and pure iron garden sheet ［ 3 ］.When rearranging magnetic circuit assembly ［ 4 ］, must satisfy with the end of contacted two Rare-Earth Cobalt of each piece pure iron garden sheet ［ 3 ］ or rare earth iron garden sheet identical polarity is arranged, or all be the N utmost point, or all be the S utmost point, this has just formed the stronger new magnetic pole of magnetic force of magnetic circuit assembly ［ 4 ］.Pure iron garden sheet has just become the tactic NSNS of magnetic circuit assembly ... magnetic pole, these new magnetic poles all have very strong attraction to the ferromagnetism impurity in the material.

Magnetic circuit assembly ［ 4 ］ is changeable according to the volume of material, but its total length must have garden, end tube length degree half less than magnetism-free stainless steel, and after in magnetic circuit assembly ［ 4 ］ is packed garden tube shell ［ 1 ］ into, leave the gap that can guarantee that assembly ［ 4 ］ is free to slide vertically in garden tube ［ 1 ］, on attracting, magnetic separtor after the impurity, make it slide into the other end of no magnetic garden tube very soon its gravity of being inverted dependence magnetic circuit assembly ［ 4 ］ like this.Ferromagnetism impurity loses magnetic attraction and just can come off from garden tube ［ 1 ］ outer wall automatically, reaches the purpose of automatic removal impurity.At the openend of no magnetic garden tube a rigid plastics handle is installed at last, and is fixed up, just formed a complete hand-held permanent-magnet separator with the bonding or mechanical way in tube end, garden.

The utility model compared with prior art has the following advantages:

1, have very strong magnetic attraction because permanent magnet and magnetic conductor consist of the magnetic circuit assembly, can the attraction rate of impurity in the material be improved greatly, the efficient of removal of contamination and quality also obviously improve.

2, because this magnetic separtor is provided with the mechanism of Automatic-falling impurity, removal of contamination efficient height, convenient and practical.

3, owing to be a bar-shaped separator that handle is arranged, thus be convenient to operation, simple.
