Description

High-precision diamond shape selector

The utility model relates to a kind of device that diamond particles is distinguished into the grain shape different brackets with method for oscillating.

Existing diamond shape selector, as the ZL92226147.4 number disclosed diamond shape selector of Chinese utility model patent, mainly by frame, feed portion, sorting portion, portion connects material, control part and angle regulator are formed, wherein sorting portion comprises base plate, the leaf spring vibrator, electromagnet and separator plate, the leaf spring vibrator is by leaf spring group and last, lower corner seat is formed by connecting, electromagnet armature is fixed on the last angle seat of one group of leaf spring, in magnet spool, there is alternating current out-of-date, armature is put by magnetic pole one suction one of electromagnet, thereby make the separator plate that is fixed on the seat of angle produce vibration, material on the separator plate just moves to diverse location regularly according to the shape of its appearance, reach the effect that classification grades, the flotation-dividing part of above-mentioned diamond shape selector is because the design performance parameter is unreasonable, its used leaf spring is a leaf spring, the angle of angle seat is incorrect, the core configuration of electromagnet and the line of coil footpath and the number of turn also cooperate inadequately, thereby make the vibration regularity of separator plate not satisfactory, the clear inadequately unanimity of the adamantine profile of the same specification grade of sorting, separating effect is unsatisfactory.

The purpose of this utility model is the shortcoming that will overcome in the above-mentioned shape selector, improves the flotation-dividing part of above-mentioned shape selector, provides a kind of separation performance better high-precision diamond shape selector.

The purpose of this utility model reaches like this, the structural parameters of preferred flotation-dividing part, the amplitude of separator plate and the characteristics of motion are become be more suitable for needs, the utility model is organic frame also, feed portion, sorting portion, parts such as portion and control part connect material, wherein, sorting portion also comprises base plate, the leaf spring vibrator, electromagnet and separator plate, but the leaf spring vibrator has 3 rectangles, 3240 epoxy novolac spring planks and 4 two groups of leaf spring groups and last that dividing plate is formed by stacking at interval by every group, lower corner seat is connected and fixed and forms, the inclination angle of every group of leaf spring group and base plate face is 109 °-111 °, be 69 °～71 ° with the inclination angle of separator plate bottom surface, two leaf spring groups and base plate and separator plate promptly form up big and down small isosceles trapezoid.

Because the utility model carried out the said structure improvement with flotation-dividing part, thereby the amplitude of separator plate is improved, the characteristics of motion more suits the needs of sorting diamond profile, thereby makes after the sorting diamond profile of same specification grade more aligned.

The utility model also makes the iron core of electromagnet to be formed by stacking with the EI form height magnetic silicon steel sheet of 0.35 millimeters thick into, 30 millimeters of the central magnetic pole width of iron core, folded thick 30 millimeters of silicon steel sheet, the line of coil directly changes 0.53 millimeter into, coil is around central magnetic pole 1790-1810 circle, thereby make the vibration of separator plate even more ideal, the better effects if of sorting.

Below be elaborated to this reality is novel with embodiment and accompanying drawing.

Fig. 1 is a front view of the present utility model, and Fig. 2 is the schematic diagram of leaf spring vibrator.

With reference to accompanying drawing 1, the upper right side of this machine is a feed portion 1, the middle part is sorting portion 2, and the portion 3 that connects material is positioned at the front portion of this machine, owing to need to clearly illustrate sorting portion on figure, thereby the major part of the portion that connects material is cutd open, only remaining few partly staying on the figure shows, and the sorting subordinate angle regulator 4 arranged, and foot is a frame 5, control part installs 6 on frame, is positioned at the forefront of this machine.With reference to attached Fig. 1 and 2, sorting portion 2 comprises base plate 7, lower corner seat 8, leaf spring group 9, last angle seat 10, separator plate 11, electromagnet 12 and magnetic receiver 13.Upper and lower angle seat and leaf spring group constitute leaf spring vibrator 14.Each leaf spring group 9 is formed by stacking at interval by 3240 epoxy novolac spring planks 15 of 3 rectangles and each two dividing plate 16 at two ends, two ends each with two pieces of bolted on the seat of angle, wherein also be fixed with the armature 17 of electromagnet 12 on the last angle seat of the one group of leaf spring group in the right simultaneously, the iron core 18 and the coil 19 of electromagnet are fixed on the magnetic receiver 13.Two lower corner seats, angle iron-type in obtuse angle, the inclination on plane is 109 °～111 ° on its leaf spring installed surface and the base plate 7, go up the angle iron-type that the angle seat is acute angle for two, the inclination angle of its leaf spring installed surface and separator plate 11 bottom surfaces is 69 °～71 °, like this, two leaf spring groups and base plate and separator plate promptly form a up big and down small isosceles trapezoid, the inclination angle on plane and lower corner seat 8 and base plate is identical on magnetic receiver 13 installed surfaces and the base plate 7, it also is 109 °～111 °, the installed surface that is magnetic receiver 13 is parallel with the lower corner seat 8 of right-hand member and the installed surface of last angle seat 10, this helps the action of armature 17, every spring plank 15 is long 120 millimeters, 3240 wide 80 millimeters, thick 3 millimeters epoxy novolac rectangular flats, fix with last lower corner seat respectively at two ends up and down along its length direction, dividing plate 15 between per two spring plank two ends all is wide 80 millimeters, and is high 20 millimeters, 3240 thick 1 millimeter epoxy novolac plates.E, the I form height magnetic silicon steel sheet of iron core 18 usefulness 0.35 millimeters thick of electromagnet 12 are formed by stacking, and be fixed on the magnetic receiver 13,30 millimeters of the central magnetic pole width of iron core, 30 millimeters of thickness, the line of coil 19 directly is 0.53 millimeter, the central magnetic pole that centers on iron core 18 is around 1790～1810 circles, and the electromagnet pulling force reaches 50 newton.
