Abstract

The invention relates to the technical field of ore dressing machinery, in particular to a saw tooth wave jigger. The saw tooth wave jigger comprises a box body, a motor, a feed chute, an ore dressing chute body and a screen. The saw tooth wave jigger is characterized by consisting of a transmission wave box and a jigging chamber, wherein the transmission wave box is driven by a speed regulating motor through a coupling to form saw toothed up-and-down motion, so that a jigging hopper moves up and down, a jigging bed is loose, ore grains are layered according to the specific weight, and the sorting rate and the recovery rate of the equipment are achieved. Because the original circumferential eccentric drive of the jigger is changed and the jigging pulsation curve is changed into the conventional saw tooth wave form from the sine wave form, the heavy ore grains in the mineral are fully settled, and the sorting rate capability of the equipment is greatly improved; because the speed regulating motor is used, the jigging frequency can be infinitely variable, the time of changing the jigging frequency by changing the diameter of a motor wheel in the past is shortened, and the labor intensity of workers is lightened; and the jigging pulsation curve is changed, so that the ascending water flow is quicker than the descending water flow, the ascending time is short, the descending time is long, the supply water quantity is effectively reduced, the water consumption is reduced by 30 to 40 percent, the treatment quantity is greatly improved, and the floor area of the equipment is effectively reduced.

Description

Sawtooth pulsation jig

Technical field

The present invention and benficiation machinery technical field, especially a kind of sawtooth pulsation jig.

Background technology

Jigging machine is one of modern gravitational separation equipment, because its disposal ability is big, it is wide to sort particle size range, and Operation and Maintenance is simple, as roughly selecting or selectedly being widely used in sorting mineral such as gold, tin, titanium, red iron, iron ore, coal, particularly in the manganese ore ore dressing field, obtained extensive use.

Traditional jigging machine mostly is the circumference eccentric drive, its jigging pulsation curves mostly is sinusoidal waveform, because rising, descent waterflow speed and action time that diaphragm movement produces are basic identical, therefore, be unfavorable for the loose and ore particle gravity segregation of jig bed, thus influenced equipment sort than and the rate of recovery.

Summary of the invention

In order to overcome these deficiencies of existing jigging machine, the invention provides a kind of sawtooth pulsation jig, be according to the theoretical layering rule of jig bed, on traditional jigging machine basis, develop and improved a kind of energy-conservation gravitational separation equipment, its jigging pulsation curves indention makes ascending current faster than descent waterflow: the rise time is short, fall time is long; Overcome sine wave, the identical defective of rising, descent waterflow and action time that the pulsation curves jigging machine produces has strengthened the shatter value of bed, has alleviated the suction effect, make the heavy ore particle in the mineral obtain abundant sedimentation, improved the sorting of equipment greatly than the ability and the rate of recovery.Itself and the contrast of sinusoidal wave jigging machine improve respectively: Sn 3.01%, W 5.5%, Pb 1.63%, Zn 2.04%; Water consumption reduces 30%-40%, and floor space reduces 1/3, and stroke can adjust, but owing to adopts electromagnetism to adjust motor to drag and make the jig frequency step-less adjustment.

The technical solution adopted for the present invention to solve the technical problems is: a kind of sawtooth pulsation jig, comprise casing, motor, feed launder, ore dressing cell body, screen cloth, it is characterized in that: by the ore dressing cell body, diaphragm of rubber, the jigging bucket, electromagnetic adjustable speed motor, transmission ripple casing, make-up pipe flange, screen cloth, feed launder is formed, transmission ripple casing is driven by shaft coupling by electromagnetic adjustable speed motor, forms that sawtooth is red to move up and down, and also moves up and down thereby drive the jigging bucket, make the loose and ore particle gravity segregation of jig bed, thus reach equipment sort than and the rate of recovery.

The invention has the beneficial effects as follows, the present invention is owing to changed original jigging machine circumference eccentric drive, its jigging pulsation curves is changed into present zig-zag by ending the dense shape of string, makes the heavy ore particle in the mineral obtain abundant sedimentation, has improved the sorting than in the sharp recovery of ability of equipment greatly; Owing to used buncher instead, make jig frequency step-less adjustment shorten original time by change motor wheel diameter size conversion jig frequency, alleviated working strength of workers; Changed the jigging pulsation curves, made ascending current faster than descent waterflow, the rise time is short, decline is long between crying, and has reduced the supply water yield effectively, makes water consumption reduce 30%-40%, has also improved treating capacity widely, has reduced occupation area of equipment effectively.

The present invention is further described below in conjunction with drawings and Examples.

1. ore dressing cell body, 2. diaphragm of rubber, 3 jigging buckets, 4. electromagnetic adjustable speed motor, 5. transmission ripple casing, 6. make-up pipe flange, 7. screen cloth, 8. feed launder.

Embodiment one,

Referring to Fig. 1-2, the present invention is by ore dressing cell body 1, diaphragm of rubber 2, jigging bucket 3, electromagnetic adjustable speed motor 4, transmission ripple casing 5, make-up pipe flange 6, screen cloth 7, feed launder 8 is formed, and transmission ripple case is driven by shaft coupling by electromagnetic adjustable speed motor, form that sawtooth is red to move up and down, also move up and down thereby drive the jigging bucket, make the loose and ore particle gravity segregation of jig bed, thus reach equipment sort than and the rate of recovery.Transmission ripple case is driven by shaft coupling by electromagnetic adjustable speed motor, form that sawtooth is red to move up and down, thereby drive the jigging bucket and also do zigzagging up and down, the high pawl water of feeding on one side, mineral are pressed proportion and granularity layering under the effect of current, therefore, the proportion ore particle different with granularity moves to mine tailing end and concentrate bucket (jigging bucket) along the direction of motion separately, is divided into concentrate and tailings at last.
