Abstract

A whirly elutriation spiral separator is a gravity separation machinery, at present, various spiral separators have the defects that the spiral disc can not apply enough loosing force to the minerals, the laying and zoning are not clear, and the recovery rate is low. The whirly elutriation spiral separator is characterized in that the manual whirly elutriation separation method and the spiral chute are combined into a whole, the radial linear groove in the original spiral disk is designed into an arc groove, so the defects of the various existing spiral separator are better solved, and the increase of the loosing force also improves the processing load; the utility model has the main technical characteristics that the whirly elutriation spiral separator comprises a speed regulating motor, an eccentric shaft, a bearing, a shaft sleeve, a spring device and a spiral disk with the arc groove; when the speed regulating motor works, the eccentric shaft drives a connecting rod connected with the shaft sleeve to press and extend the spring, at the same time, the counteraction of the spring force makes the spiral disk on the shaft sleeve whir at variable speed, at this moment, ore pulp in the spiral disk can be whirly elutriated under the action of water medium so as to achieve the goal of separation.

Description

The elutriation spiral concentrator circles round

Technical field:

The utility model belongs to gravity separation machinery.

Background technology:

At present, spiral shell is executed preparation equipment to be had: common spiral chute, the electric screw chute, dither spiral chute etc., above-described spiral concentrator is to utilize ore pulp for the helical movement along the spiral bottom surface downwards, the ore pulp of motion is in fluid dynamic, gravity, under the comprehensive function of centrifugal inertial force and bottom surface frictional force, make the different mineral matter generation layering of proportion, the mineral matter of layering, under the effect of spiral flow and radial circular flow, when helicla flute moves downward, divide band along groove width, heavy mineral is distributed in inner edge, and light mineral matter is distributed in outer rim, separate gently the purpose of heavy mineral matter thereby reach; This kind equipment is big because for the treatment of capacity, and operating cost is low, and is widely used in roughly selecting of ore.But in the production reality, in the common spiral chute, the water in the ore pulp is more easily gone to the outer rim of helical disk, causes the heavy mineral matter in the dish to pile a phenomenon and the ore deposit occurs ending and rise inadequately because of loose, has a strong impact on the ore dressing effect; And electric screw chute and other spiral chute, though to a certain degree improved loose power and the concentrate grade of bottom surface to mineral matter, pivoting of helical disk increased the centrifugal force of ore pulp in the dish, according to the centrifugal force formula:

Rotating speed is big more, and the centrifugal force that the mineral matter that quality is big just is subjected to is big more, has caused the concentrate band to move the tailing zone that enters the dish outer rim with the part heavy mineral outward, influences the rate of recovery, and the little loose power of rotating speed is not enough; Cutting in the helical disk of the above spiral concentrator simultaneously, be the radial alignment cutting, during these cuttings of ore pulp process, cutting is carried out rigid stopping to ore pulp, heavy mineral matter in the ore pulp directly covers cutting easily, therefore the radial alignment cutting guides heavy mineral matter to make the weak effect that moves radially, and causes this kind equipment to catch heavy ore deposit ability, and the rate of recovery is low; Above defective makes this kind equipment poor general in current resource, and the ore grain size refinement epoch present superseded gesture.

Summary of the invention:

The purpose of this utility model is in order to solve above-mentioned various spiral concentrator, and is not strong to the loose power of mineral material on the helical disk, layering, divides and to be with not obviously, and mine tailing contains fine-grained heavy minerals matter many defective designs; The ore dressing mode that its simulation is manually circled round and eluriated can promptly be carried out loosely to the mineral material on the helical disk, eluriate layering and divide band; The utilization of camber line cutting spiral card has also strengthened the collecting ability to fine-grained heavy minerals simultaneously, has improved the rate of recovery.

The purpose of this utility model is achieved by the following technical solution.

With the electronic at the uniform velocity at the uniform velocity whirligig of the spiral concentrator of rotation, be designed to the speed change revolving gear; With radially protruding (or recessed) cutting of existing helical disk, be designed to arc protruding (or recessed) cutting; Its technical characterictic is:

Speed change revolving gear recited above is: by buncher, eccentric shaft, bearing, axle sleeve and spring assembly constitute.

Spring assembly recited above is by one one end band pin-and-hole, and other end band is transferred the connecting rod of screw, and link pin, spring, baffle plate constitute.

The helical disk of band arc recited above cutting is: radial alignment protruding (or recessed) cutting with in the existing helical disk is designed to camber line protruding (or recessed) cutting.

The present invention adopts this speed change revolving gear, it can strengthen the loose power of helical disk to mineral matter by improving the eccentric shaft rotating speed, and the helical disk that is fixed on the axle sleeve is only done the speed change circumnutation, the motion of not pivoting, thereby avoided the influence of centrifugal force to ore dressing, this approximate working method of manually circling round and eluriating has solved mineral matter loose power deficiency on helical disk preferably, and layering, branch are with unconspicuous defective; Simultaneously, adopt arc cutting helical disk technology,, become and used the camber line cutting, the heavy mineral matter that sinks to the bottom that moves downward is taken advantage of a situation the rigid guidance mode that stops of original radial alignment cutting counterweight mineral matter

Guiding moves radially, it is more smooth and easy that heavy mineral matter is flowed, strengthened the collecting ability of trying to get to the heart of a matter in the face of heavy mineral matter, this utility model equipment simultaneously, can also be by the speed of control motor, adjust the cyclotron frequency of helical disk, adjust relaxing of spring, helical disk is circled round as speed change, thereby make separation index better, the enhancing of loose power has simultaneously also improved the treating capacity of existing equipment greatly, the employing of these technology has been played poplar length to this kind equipment and has been kept away short effect, has improved the concentrate grade and the rate of recovery.
