Abstract
The utility model discloses a dry magnetic separator. The dry magnetic separator is characterized in that magnetic bodies are arrayed along the inner wall of the semi-circumference in a magnetic cylinder, wherein the arraying manner of the magnetic bodies is that magnetic poles of same attributes are arrayed in parallel, and N poles and S poles respectively occupy one quarter of the circumference; a magnetic block with the opposite magnetic pole is additionally arranged between every two magnetic poles of the same attributes and is an oblique block type magnetic block, one end of the oblique block type magnetic block is wide, and the other end of the oblique block type magnetic block is narrow. According to the dry magnetic separator, the strength of a magnetic field can be increased, the depth of the magnetic field is doubled than that in the prior art, high ore recovery rate and good separation effect can be realized under the same separation grade, and the ore grade can be greatly improved.
Description
Technical field
The utility model relates to mining machinery field, refers to especially a kind of dry-type magnetic extractor.
Background technology
As shown in Figures 1 and 2, the magnetic cylinder inner magnet of traditional dry-type magnetic extractor adopt S the N utmost point or SS the conventional arrangement method of the NN utmost point.These two kinds of aligning method Surface field intensity are general, and the degree of depth overhanging pulling force in magnetic field is short, and the rate of recovery is low, race tail is large, can only be applicable to coarse granule dry separation, for the fine grained that dry grinding processes through ball milling, cannot satisfy the demands, cause this kind of dry-type magnetic extractor rate of recovery low, cannot improve the grade of ore.
Utility model content
The utility model proposes a kind of dry-type magnetic extractor, adopt new pole arrangement mode, solved prior art dry-type magnetic extractor magnetic field intensity low, magnetic field depth as shallow, the problem such as the rate of recovery is low.
The technical solution of the utility model is achieved in that
A dry-type magnetic extractor, its special character is:
Inwall along semi-circumference in its magnetic cylinder is arranged with magnet, and the magnetic pole that the arrangement mode of described magnet is same alike result is arranged side by side, and the N utmost point and the S utmost point respectively account for quadrant.
As the further improvement to technique scheme, between every two same alike result magnetic poles, install the magnetic patch of reverse magnetic pole additional.
In order conveniently to install the magnetic patch of reverse magnetic pole additional, this magnetic patch is the narrow sloping block type magnetic patch of a head breadth other end point.
Concrete, this kind of magnetic cylinder inner magnet arrangement mode be this same attribute of NNNNNN \ SSSSSS side by side and two kinds of modes that attribute is half-and-half arranged.Between every two N utmost point magnets, install S utmost point magnetic patch additional, between every two S utmost point magnets, install N utmost point magnetic patch additional.
The technical solution of the utility model, due to broken original traditional S the N utmost point or SS the conventional arrangement method of the NN utmost point, utilize the SSSSSS utmost point and double arrangement mode of the NNNNNN utmost point, and the magnet arrangement mode that installs again reverse magnetic pole inclined magnetic patch between same attribute magnetic pole additional, can improve magnetic field intensity, make magnetic field depth ratio traditional handicraft deepen one times, can be when equal sorting rank, realize ore recovery ratio high, good separation effect, can improve the grade of ore in high depth ground.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is a kind of magnetic cylinder inner magnet arrangement mode structural representation of the dry-type magnetic extractor of prior art;
Fig. 2 is the another kind of magnetic cylinder inner magnet arrangement mode structural representation of the dry-type magnetic extractor of prior art;
Fig. 3 is the magnetic cylinder inner magnet arrangement mode structural representation of technical solutions of the utility model dry-type magnetic extractor.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 3, dry-type magnetic extractor of the present utility model, its special character is:
Inwall along semi-circumference in its magnetic cylinder is arranged with magnet, and the magnetic pole that the arrangement mode of described magnet is same alike result is arranged side by side, and the N utmost point and the S utmost point respectively account for quadrant.
As the further improvement to technique scheme, between every two same alike result magnetic poles, install the magnetic patch of reverse magnetic pole additional.
In order conveniently to install the magnetic patch of reverse magnetic pole additional, this magnetic patch is the narrow sloping block type magnetic patch of a head breadth other end point.
Concrete, this kind of magnetic cylinder inner magnet arrangement mode be this same attribute of NNNNNN \ SSSSSS side by side and two kinds of modes that attribute is half-and-half arranged.Between every two N utmost point magnets, install S utmost point magnetic patch additional, between every two S utmost point magnets, install N utmost point magnetic patch additional.
The technical solution of the utility model, due to broken original traditional S the N utmost point or SS the conventional arrangement method of the NN utmost point, utilize the SSSSSS utmost point and double arrangement mode of the NNNNNN utmost point, and the magnet arrangement mode that installs again reverse magnetic pole inclined magnetic patch between same attribute magnetic pole additional, makes magnetic field intensity high, magnetic field depth ratio traditional handicraft is deepened one times, can be when equal sorting rank, realize ore recovery ratio high, good separation effect, can improve the grade of ore in high depth ground.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (3)
