First and second magnetic pole head 1,3 of said structure is sickleshaped from front view in terms of profile, is arranged symmetrically in after bottom fixed block 4, the point position closely located (see Fig. 1) of the first magnetic pole head 1 and the second magnetic pole head 3.
In said apparatus, the first magnetic pole head 1 is flexibly connected with described fixed block 4 and is: the afterbody of the first magnetic pole head 1 is provided as the trapezoid cross section groove 11 of attachment structure；
The trapezoid cross section guide rail 41 being conformed with bottom fixed block 4, the trapezoid cross section groove 11 of trapezoid cross section guide rail 41 and described first magnetic pole head 1 matches；
The trapezoid cross section groove 11 of the first magnetic pole head 1 is enclosed within the trapezoid cross section guide rail 41 of described fixed block.
Such first magnetic pole head 1 both can slide on the trapezoid cross section guide rail 41 of fixed block 4, in turn ensure that the first magnetic pole head 1 will not unclamp from fixed block 4 and comes off, and can be fully contacted magnetic conduction.
Preferably, the second magnetic pole head 3 may be used without the structure being similar to the first magnetic pole head 1 connection fixing block 4 and is attached with fixed block, and only the second magnetic pole head 3 is fixing connection with fixed block 4, can not slide after connection on fixed block 4.While this connected mode also ensures that the second magnetic pole head 3 will not get loose from fixed block 4, it is ensured that both are fully contacted magnetic conduction.
As shown in Figure 1, said apparatus also includes: scale 11, it is arranged on bottom described fixed block 4, one end contacts with described second magnetic pole head 3 afterbody, scale 11 is provided with magnetic field intensity scale, reading magnetic field intensity by the scale on the adjusting position correspondence scale of adjusting screw rod, the length of scale 11 is as the criterion to cover the adjustable distance between first and second magnetic pole head.
As it is shown in figure 1, the adjusting screw rod in said apparatus includes: the first screw rod the 10, second screw rod 5 and adjusting nut 6；
Wherein, the first screw rod 10 is connected with described first magnetic pole head 1, is provided with right-handed thread；Described second screw rod 5 is connected with described second magnetic pole head 3, is provided with left hand thread；
First screw rod 10 is relative with the free end of the second screw rod 5, connects by regulating the adjusting nut 6 of two screw rods relative position.
In said apparatus, the adjustable range 12 between the first magnetic pole head 1 and the head of the second magnetic pole head 3 is 0.5～10mm.
Different according to the magnetic field intensity selecting permanent magnet, this magnetic detection apparatus can realize magnetic field intensity and be adjusted between 0.3T～1.5T.
In said apparatus, arranging permanent magnet 13 in fixed block 4 is: arranging containing cavity in fixed block 4, described permanent magnet 13 is arranged in described containing cavity；Containing cavity is externally provided with baffle plate (including bottom baffle 9 and two side shields 7).This structure can facilitate placement and the replacing of permanent magnet.
Below in conjunction with specific embodiment, the magnetic detection apparatus of the present invention is described further.
This magnetic detection apparatus, it is be arranged symmetrically in bottom fixed block constituted (just seeing Fig. 1 with view) by two magnetic pole heads 1,3 that shape is essentially identical, permanent magnet 13 it is provided with in fixed block 4, first magnetic pole head 1 and fixed block 4 junction be guide rail structure (as shown in the figure, what adopt is trapezoid cross section guide rail), make the first magnetic pole head 1 can slide on guide rail structure, so can regulate the distance between the second magnetic pole head 3.Being connected by adjusting screw rod between first magnetic pole head 1 with the second magnetic pole head 3, adjusting screw rod is made up of the first screw rod 10 being provided with right-handed thread and the second screw rod 5 and the adjusting nut 6 being provided with left hand thread；Two screw rods 10,5 is fixing to be set up separately on first and second magnetic pole head 1,3, and two screw rods 10,5 free end is relative, adjusting nut 6 connect, and rotating adjusting nut 6 can drive two screw rods 10,5 thus the distance that changes between two magnetic pole heads 1,3.Adjusting nut 6 can adopt long nut, the maximum adjustable distance that can meet between two magnetic pole heads 1,3 to be as the criterion.
Further, can arranging scale 11 on this magnetic detection apparatus, scale 11 may be provided in the bottom of fixed block 4, the position of the adjusting nut 6 of corresponding mark adjusting screw rod, scale is marked with scale, can read scale high scale, different scale correspondence different magnetic field intensity by adjusting nut 6 end face.
Preferably, antirust treatment can be done in this magnetic detection apparatus appearance, as being respectively provided with antirust coat at each parts surface, it is preferable that chromium plating process can be carried out at each parts surface, form chromium plating antirust coat.
The operation principle of this magnetic detection apparatus is as follows:
Permanent magnets 13 is arranged between the first magnetic pole head 1 and the second magnetic pole head 3, two magnetic pole heads are arcuate structure, are gradually reduced from afterbody to head sectional area, and this structure is conducive to the Guan Bi of magnetic circuit, improving magnetic energy utilization rate, the head of each magnetic pole head has the effect converging the magnetic line of force；Because first and second screw rod of adjusting screw rod is provided with helix in opposite direction, passing through rotating adjusting nut, it is possible to regulate the distance between two screw rods, driving the first magnetic pole head 1 head to slide, thus regulating two magnetic pole head head distances；When two magnetic pole head head distances are less, the two magnetic pole head head magnetic lines of force are comparatively intensive, form highfield district (may be up to 1.5 teslas) at two magnetic pole head heads；When two magnetic pole head distances are bigger, the two magnetic pole head head magnetic lines of force are comparatively sparse, form low-intensity magnetic field district at two magnetic pole head heads；As long as so rotating adjusting nut changes the position of this nut and the position of the first screw rod, the density degree of the two magnetic pole head head magnetic lines of force just can be changed, thus obtaining corresponding magnetic field intensity at two magnetic pole head heads, it is achieved the purpose that magnetic field intensity is controlled.Can scale subscript fixed-field intensity (can according to obtain adjustments distance and the relation of cartridge magnetic field intensity, magnetic field value is indicated on the graduated disc of scale), with facilitate adjustment two magnetic heads between distance, to obtain required magnetic field intensity,.Because different magnetic materials have different relative magnetic susceptibilities, this device magnetic field intensity is adjustable, and the separation of multiple different magnetic materials is respectively provided with the suitability, and two magnetic pole head distance variables simultaneously, applicable mineral granularity is wider.Time as less in two magnetic pole head spacing, it is adaptable to raw meal particle size is less, when two magnetic pole head spacing are bigger, it is adaptable to the bigger material of granularity.
In sum, the permanent magnetism magnetic detection apparatus of the portable controlling magnetic field of the present invention, have that volume is little, not electricity consumption, magnetic field intensity is adjustable, and most high magnetic field intensity is up to 1.5T, it is easy to laboratory use and field usage, can conveniently detect whether material has the power of magnetic and magnetic, and the separation of different magnetic material can be realized according to the difference of magnetic.
The above; being only the present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, any those familiar with the art is in the technical scope of present disclosure; the change that can readily occur in or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
