Abstract

The utility model relates to a counter polar type permanent magnetic separator for magnetic separation of ferromagnetism materials in fine powder materials (or wet materials), comprising a plurality of permanent magnetic rods arranged in parallel and side by side, wherein, adjacent side edges of each permanent magnetic rod are arranged in the counter polar; each permanent magnetic rod is surrounded outside by a sleeve made of non magnetic materials, the sleeve has a length longer than that of the permanent magnetic rod which can slide backwards and forwards in the sleeve; the front half section of the gap between sleeves is a adsorbing work area. The utility model adopts the permanent magnetic rod as the working magnet, thereby the structure is simple, the cost is low, and the magnet width is small, the magnet gaps are arranged closely, accordingly, the occupied area is reduced and the work efficiency is increased.

Description

To the polar permanent magnetic magnetic separating device

Technical field

The utility model relate to a kind of to the ferromagnetic materials in the powder material (or wet type material) carry out magnetic separation (or magnetic separation) to the polar permanent magnetic magnetic separating device.

Background technology

By existing theory as can be known, a magnets N (or S) is extremely placed very near position when forming less clearance with S (or N) utmost point of another magnet, can produce in this gap very big magnetic induction intensity to pole field.Utmost point formula magnetic separating device is utilized this principle exactly, many bar-shaped magnetic are arranged in parallel side by side, leave the gap between each magnet, and make the polarity opposite (promptly utmost point mode being arranged) of the adjacent side of adjacent two magnets, thereby form have a plurality of strong magnetic gap sieve texture, when material during by the gap, ferromagnetic materials promptly is attracted on the magnet, the material that is adsorbed when needs is then closed magnetic field when magnet separates, and it is broken away from voluntarily.Because electromagnetism magnetic field can close easily, thereby adopts the electromagnetism magnet to utmost point formula magnetic separating device more, and permanent magnetic field is owing to be difficult for closing, thereby is not used.But it is complicated that electromagnetic equipment exists structure, and cost is higher, and its magnet diameter is bigger, cause between each magnet gap arrangement thinner, thereby the work area that need take is bigger.

Summary of the invention

Technical problem to be solved in the utility model is, provide a kind of simple in structure, take up room little, lower-cost to the polar permanent magnetic magnetic separating device.

Of the present utility model the polar permanent magnetic magnetic separating device is included the many Permanentmagnet bars that are arranged in parallel side by side, the adjacent side of each Permanentmagnet bar is to arrange utmost point mode, be with a sleeve pipe of making by non-magnet material every Permanentmagnet bar periphery, the length of sleeve pipe is greater than the length of Permanentmagnet bar, Permanentmagnet bar can slide front and back in sleeve pipe, form long and narrow gap between each sleeve pipe, preceding half section of the gap is the absorption workspace.

The utility model adopts Permanentmagnet bar as the work magnet, and it is simple in structure, and cost is low, and the magnet width is less, makes gap arrangement comparatively dense between magnet, thereby can reduce the area that takies, and increases work efficiency.

Fig. 2 is that Permanentmagnet bar of the present utility model is positioned at the structural representation of sleeve pipe during the second half section;

Fig. 3 is an end face structure schematic diagram of the present utility model.

The specific embodiment

As shown in Figure 1 and Figure 2, this to the polar permanent magnetic magnetic separating device with the Permanentmagnet bar 1 that is arranged in parallel side by side as the work magnet, the polarity of each Permanentmagnet bar adjacent side is opposite, promptly so that utmost point mode is arranged (as shown in Figure 3), Permanentmagnet bar 1 periphery is with the sleeve pipe 2 that non-magnet material is made, the length of sleeve pipe is greater than the length of Permanentmagnet bar, Permanentmagnet bar can slide front and back in sleeve pipe, preceding half section of the gap is absorption workspace 3 between each sleeve pipe, is connected and fixed between each sleeve pipe or by the dividing plate 4 that a plurality of non-magnet materials are made.

Of the present utility model can be the single layer structure (as Fig. 3) that a row is only arranged to the bar magnet that is arranged side by side in the polar permanent magnetic magnetic separating device and sleeve pipe, can also be distributed with many rows from top to bottom, constitutes sandwich construction, to strengthen the magnetic separation effect.

When carrying out magnetic concentration working, Permanentmagnet bar 1 is positioned at preceding half section (as Fig. 1) of sleeve pipe 2, and the material for the treatment of sorting passes through from absorption workspace 3, and ferromagnetic materials is attracted to the preceding half section outer surface of sleeve pipe 2; When ferromagnetic materials absorption is accumulated to a certain degree, when it is broken away from, Permanentmagnet bar 1 is moved to the second half section (as Fig. 2) by preceding half section of sleeve pipe 2, the magnetic field of absorption workspace 3 is disappeared by operating mechanism, the material that is adsorbed promptly breaks away from voluntarily, finishes assorting room.
