Disclosure of Invention
The invention aims to provide a circular disc type concentrator and a beneficiation method, which are simple in structure, convenient to install and high in enrichment ratio, and can separate high-grade concentrate.
To solve the above problems, an aspect of the present invention provides a circular disc concentrator including: the device comprises a circular disc type ore dressing unit and a three-dimensional bracket unit; the circular disc type ore dressing unit comprises a circular sorting disc, a rotating device for driving the circular sorting disc to rotate and a mineral aggregate receiving disc arranged below the circular sorting disc for receiving materials; the three-dimensional support unit is provided with an ore feeding pipe, a concentrate flushing pipe of the ore feeding pipe and a speed reducing motor connected with the rotating device. When the ore feeding device is used, the water feeding pipe drips water onto the separation disc, the separation disc rotates under the action of the rotating device and forms a layer of flow film on the surface of the separation disc under the action of the water feeding pipe, the ore feeding pipe on the support injects ore pulp with the concentration of 30-50% onto the separation disc in rotation, and when the ore pulp enters the flow film and rotates along with the separation disc. The Bygrano theory shows that: when the fluid is acted by a shearing force, the solid particles in the fluid are acted by a dispersing pressure in the direction perpendicular to the shearing force in addition to the shearing force in the same direction, so that the materials are layered or suspended. Mineral particles and gangue are different in density and are finally separated under the action of centrifugal force to enter the mineral aggregate receiving disc, wherein the mineral aggregate receiving disc can be divided into different areas to respectively receive concentrate, middlings and tailings, and the mineral particles after being separated can be classified in more stages. Wherein the rotating means may be combined using a sprocket and a motor, a rotation scheme that enables precise control of the rotational speed is preferred.

The further technical scheme is that the circular sorting disc is an inward concave conical ring with a hole in the middle of 2-6 m in diameter, and the diameter of the hole in the middle of the inward concave conical ring is 0.6-3 m. Wherein the circular ring-shaped sorting disc may have a diameter of 2, 3, 4, 5, 6 meters, preferably 2 to 4 meters, including but not limited to the above examples. When the diameter of the circular ring-shaped sorting disc is too small, the ore pulp cannot be fully separated, and when the diameter of the circular ring-shaped sorting disc is too large, the requirement on the manufacturing process is too large, so that the ore pulp cannot be fully separated. The circular separating disc is an inward concave conical ring with a middle opening, ore pulp can be separated on the separating disc for a longer time under the influence of centrifugal force and gravity after falling onto the separating disc, and finally falls into the opening in the middle of the separating disc, and at the moment, the mineral aggregate receiving disc is arranged below the opening. The diameter of the middle hole can be 0.6-3 m, the diameter of the middle hole depends on the diameter of the separation disc, when the diameter of the middle hole is too small, separated ore pulp cannot be separated through the ore material receiving disc, and concentrate, middling and tailings are easy to accumulate together.

The 1/2 taper angle of the sorting tray may be 172, 173, 174, 175, 176, 177, 178, 179.9 degrees, including but not limited to the above examples, too large or too small a taper angle of the sorting tray may adversely affect the sorting, when too large a taper angle the sorting surface of the sorting tray approaches a plane, the sorting performance may be reduced sharply or even the sorting may not be completed, and when too small a taper angle the inclination angle of the sorting surface is too large, the time for sorting the slurry on the sorting tray is not sufficient.
According to a further technical scheme, the water supply pipes are arranged along the circumference of the sorting tray and drop water onto the sorting tray through the water dropping holes. Wherein the distance between the drip hole on the feed pipe is less than or equal to 1.5cm, can adjust according to actual conditions, need make the drip hole with the water drip to the use part that the whole separation dish was covered to the flowing film that forms on the separation dish, be the basis of carrying out the separation to the ore pulp.
A further technical scheme is that an arc-shaped magnetic field is detachably arranged below the sorting disc. Use magnetic field can improve separation efficiency when sorting strong magnetic mineral, use and to dismantle arc magnetic field and install in the separation dish below, can use same equipment to select different types of mineral, practice thrift the cost. The annular magnetic field can be composed of a plurality of square magnet blocks, the arrangement with the same radian as the edge of the sorting disc can be adopted, the arrangement can also be carried out by adopting a radian smaller than the radian of the edge of the sorting disc, and the circle of the arc-shaped magnetic field and the circle of the sorting disc are deviated. The arc magnetic field can be installed on the three-dimensional support unit, and the arc magnetic field can be omitted when non-magnetic or weakly magnetic mineral aggregates are sorted, so that the non-magnetic or weakly magnetic mineral aggregates can be stored after being detached. After the arc-shaped magnetic field is installed, the water supply of the water supply pipe to the separation disc needs to be increased, and mineral particles are prevented from being accumulated on the separation disc due to the magnetic field.
The ore feeding pipe is arranged at a point P above the separation disc, the point P is arranged at a position close to the edge of the separation disc, and the concentrate flushing pipe is arranged behind the point P along the rotation direction of the separation disc, is close to the middle hole and faces the center of the separation disc. The feed pipe feed opening may be located at any point above the tray, preferably at point P near the edge of the tray, where the particles in the slurry have a longer time to stratify before eventually falling into the tray central opening.

According to a further technical scheme, the arc-shaped magnetic field comprises a strong magnetic section and a weak magnetic section, the strong magnetic section is arranged below the point P, and the weak magnetic section is arranged below the strong magnetic section along the rotating direction of the sorting disc. The magnetic field is suitable for arranging a weak magnetic field which is N, S, N, S … … alternately arranged, the magnetic system rolling of the strong magnetic mineral particles can be generated due to the alternate magnetic pole change, the gangue particles and the fine mud mixed in the strong magnetic mineral particle group can be separated, and the length of the magnetic field is suitable for arranging a half length of the whole process of the annular sorting area of the sorting disc. Compared with 4-5 magnetic pole heads of a common magnetic separator, the annular separation surface of the arc-shaped magnetic field can have as many as 30 magnetic pole heads, and ore pulp can be rolled through dozens of times of magnetic systems after passing through the arc-shaped magnetic field, so that high-quality ore concentrate can be separated. The weak magnetic field is only large enough to enable the ferromagnetic mineral particle groups to generate magnetic induction and be attracted by the magnetic field to greatly slow down the movement speed, and the magnetic field can be taken away by water flow only when the magnetic field is completely lost. The intensity of the weak magnetic field is not enough to influence the weak magnetic mineral particle group, and the movement speed of the weak magnetic mineral particles is not influenced. Therefore, the weakly magnetic minerals are selected by gravity, and the weakly magnetic minerals and the strongly magnetic minerals are effectively separated by the weak magnetic field. If the recovery of strong magnetic and weak magnetic minerals is not considered, a weak magnetic field with a short arc line can be arranged, the range of the magnetic field is slightly larger than the width of the feed opening of the ore feeding pipe, so that the strong magnetic minerals are induced by the magnetic field to form magnetic chains and magnetic bundles, and the magnetic chains and the magnetic bundles leaving the magnetic field can be quickly taken away by water flow after the density of the magnetic chains and the magnetic bundles is reduced due to the increase of the volume. Only weakly magnetic minerals are left on the sorting surface of the sorting disc for the gravity sorting process, so that better weakly magnetic concentrate can be obtained. If the minerals need to be sorted and simultaneously contain nonmagnetic heavy minerals, ferromagnetic minerals and weakly magnetic minerals, a variable magnetic field from a high-intensity magnetic field to a low-intensity magnetic field can be arranged, the high-intensity magnetic field is arranged below a feeding port of a feeding pipe, the magnetic field strength can reach over 12000 gauss, the magnetic minerals can be retained at the edge of a sorting ring in the high-intensity magnetic field area and only move along with the sorting ring, the nonmagnetic minerals and the magnetic minerals are separated, and the separation of the nonmagnetic minerals is finished by gravity sorting due to density difference. The magnetic minerals leave the range of the strong magnetic field along with the rotation of the sorting disc and then enter the weak magnetic field arrangement area, the weak magnetic minerals are separated when moving in the weak magnetic field, finally the weak magnetic minerals are effectively separated under the action of gravity, and the strong magnetic minerals can be also taken away by the rapid water flow after leaving the direction of the weak magnetic field.
The further technical scheme is that the device further comprises a spraying device, wherein the spraying device is arranged above the sorting disc and sprays water mist to the surface of the sorting disc. The atomizing device sprays atomized water drops on the sorting surface, the atomized water drops gently fall on the flowing film of the sorting disc, the flowing film plays a certain stirring role, and the separation of mineral particles in the flowing film can be accelerated under the condition that the normal movement of the flowing film is not damaged.

s1: starting a speed reduction motor to enable the sorting disc to rotate at the speed of 0.5-1.5 r/min;
s2: starting a water supply pipe to spray the spray washing water to the surface of the sorting disc;
s3: preparing ore materials into ore pulp with the concentration of 30-50%, and injecting the ore pulp into a point P on a separation disc through an ore feeding pipe at a preset flow rate;
s4: and collecting the sorted mineral aggregate through a mineral aggregate receiving disc.
