Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, the invention will be further described, to help understanding this
Bright content.
As Figure 1-3, the invention provides a kind of mineral magnetic separator, including sorting mechanism 4 with super
Magnetic conductor 1；Described superconducting magnet 1 is solenoid type superconducting magnet 1, two magnetic poles of this superconducting magnet 1
Place is respectively arranged with top crown 2 and bottom crown 3；Described sorting mechanism 4 includes rotating mechanism and at least
Individual sorting frame 402；Described sorting frame 402 is arranged on the edge of described rotating mechanism, around rotating mechanism
Rotary shaft 401 rotates；Described top crown 2 is provided with the groove 202 for accommodating described rotating mechanism；Institute
State the pole plate at groove 202 place to extend formation along the axis direction of rotating mechanism rotary shaft 401 and stretch into rotation
Magnetic field end 201 between mechanism edge and rotary shaft 401；The magnetic field end 201 of described top crown 2 and under
Upper protruding 204 and lower convexity 301 cooperated it are symmetrically arranged with on the relevant position of pole plate 3；Described
Upper protruding 204 down-set on top crown 2, described lower convexity 301 sets up on bottom crown 3.
Magnetic field end 201 stretches between rotating mechanism edge and rotary shaft 401, it is possible to ensure the turnover of magnetic separation frame up and down
The position major part of pole plate has the magnetic line of force to pass through.Groove 202 is set and is in order at the need installing sorting mechanism 4
Ask consideration, but the setting of groove 202 also brings inconvenience to sorting.Two the different magnetic being parallel to each other
The magnetic line of force forming magnetic field between the pole plate of pole is uniform, but the present inventor in experiments it is found that, arranges
After groove 202, the magnetic field intensity of position corresponding with groove 202 between upper bottom crown is more weak (due to groove
Magnetic source is not had at 202, few with the magnetic induction line of groove 202 correspondence position between upper bottom crown), and herein
It is just the groundwork position of sorting magnetic mineral grain, therefore, when using such scheme, separating effect
Unsatisfactory.And generally, it is desirable to obtain preferable separating effect, superconducting magnet can only be improved as far as possible
The magnetic field intensity of 1, but in the case of the magnetic field intensity of more than 1.5T, go to increase the field of superconducting magnet 1 again
By force, either technology and cost are required for paying bigger cost.For solving this problem, institute in the present embodiment
State the magnetic field end 201 of top crown 2 and be additionally provided with the extension 203 close to bottom crown 3 direction, described on
Protruding 204 are arranged on described extension 203.Described protruding 204 and the cross section of lower convexity 301 be
The shape become narrow gradually to tip by base portion.So, between upper protruding 204 relative and lower convexity 301
The magnetic induction line formed is the spindle that middle thick two is thin, and groove 202 both sides are equipped with projection, such two
The spindle magnetic induction line on limit mutually extrudes and makes the field intensity of groove 202 become strong, thus reaches to make with less cost
The purpose that at groove 202, magnetic field intensity increases.Upper bottom crown is symmetrical arranged projection, changes magnetic line of force distribution
Situation, solves the field strength skewness of the pole plate caused because of groove 202, and sort location field intensity is relatively
Weak deficiency.
It is provided with between described top crown 2 and bottom crown 3 and props up top crown 2 and the support member of bottom crown 3
5.Support member 5 quantity no less than two, be respectively provided with described superconducting magnet 1 both sides, support member 5
It is uniformly arranged on the edge of bottom crown 3.In the present embodiment being 4, bottom crown 3 is shaped as rectangle, and 4
Individual support member 5 is separately positioned on four corners.The length at described support member 5 two ends is tubular not less than helical
The two ends end of superconducting magnet 1 away from.So, many support members 5 are by the uniform load-bearing of upper bottom crown, and it is right to be formed
The support of upper bottom crown, it is ensured that upper bottom crown is unlikely to because being in superconducting magnet 1 magnetic field the adhesive produced
Power makes superconducting magnet 1 be born by excessive load-bearing.Described superconducting magnet 1 is the tubular superconducting magnet of helical 1,
Including superconducting coil 101 and shell 102.In the present embodiment, top crown 2, bottom crown 3 and support member
Connected mode between 5 can be following several or several combinations, and such as support member 5 props up bottom crown,
Support member 5 two ends are respectively and fixedly installed on bottom crown, and it is another that support member 5 one end props up up/down pole plate 3
One end is fixedly mounted on lower/upper pole plate 2.It is provided with for installing on described top crown 2 or bottom crown 3
Described rotating mechanism rotary shaft 401 mounting groove 7.The technical scheme of the present embodiment also includes rotating mechanism
The routine techniques of the art such as driving means, mineral passage, product collecting machine structure and pulsing mechanism,
Do not repeat at this.
The work process of the present invention is as follows, and rotating mechanism drives soft magnetic materials make or be contained with soft magnetic medium
Sorting frame 402 rotate, around rotary shaft 401, the magnetic field that the upper bottom crown of turnover is formed, produce in this magnetic field
Magnetic.When mineral containing magnetic-particle pass through the sorting frame 402 in this magnetic field, it is sorted frame 402 and inhales
Live thus separate with the non-magnetic particle in mineral.When sorting frame 402 produces this magnetic field with magnetic-particle
Demagnetization, magnetic-particle falls and is collected.
The above is only the preferred embodiment of the present invention, it is noted that general for the art
For logical technical staff, under the premise without departing from the principles of the invention, it is also possible to make some improvement and profit
Decorations, these improvements and modifications also should be regarded as protection scope of the present invention.
