Description
Technical Field
The utility model belongs to the technical field of the mineral processing equipment technique and specifically relates to centrifuge of ore dressing usefulness.
Background
The cassiterite has high specific gravity but is crisp, and is easy to be crushed in the process of mining and mineral separation to form micro-fine cassiterite, and the cassiterite is difficult to recover by the conventional mineral separation method and is finally lost in tailings of the mineral separation process, so that the waste of cassiterite resources is caused. The sorting and recycling of the micro-fine cassiterite is one of the technical problems in the field of mineral separation.
At present, the dressing recovery of the superfine cassiterite adopts a dressing centrifuge to recover the cassiterite. The main working part of the centrifugal separator is a rotary drum which is supported on a bracket and is driven by a motor in a belt transmission mode to rotate at a certain rotating speed. The ore pulp is sent to the inner wall depth of the rotary drum through the ore feeding nozzle by the ore feeding separator. The ore pulp rotates along with the rotary drum, and under the action of centrifugal force, minerals begin to be sorted. The heavy mineral deposits on the inner wall of the rotary drum and rotates along with the rotary drum, the light mineral particles in the ore pulp rotate along with the rotary drum at a certain differential speed, the light mineral particles are washed by rinsing water all the time in the rotating process, the rinsing water carries the light mineral particles to flow from the ore feeding end to the ore discharging end along the gradient direction of the rotary drum, and the light mineral particles are discharged from the tail end through the ore discharging separator to obtain the tailings. After a certain time of sorting, the feeding ore separator automatically turns to the position for discharging the concentrate, and feeding of the ore into the rotary drum is stopped. After the tailings are discharged, the ore discharging separator automatically rotates away from the original normal position to prepare for intercepting concentrate, then the high-pressure flushing water valve is automatically opened, the concentrate deposited on the inner wall of the rotary drum is flushed down by the high-pressure flushing water, and the high-pressure water valve is automatically closed after the concentrate is flushed. After the concentrate is discharged, the ore discharging separator and the ore feeding separator automatically reset to start the next separation cycle.
Many auxiliary mechanisms of the centrifugal concentrator mainly comprise a plurality of main parts such as a feeding device, an ore discharging device, a washing water device, rinsing water and an operation program control device of the feeding device, the ore discharging device, the washing water device, the rinsing water and the operation program control device. The main working part of the centrifugal separator is a truncated cone-shaped rotary drum, the half cone angle is 3-5 degrees, the rotary drum is fixed on a horizontal shaft by means of a support, and the rotary drum is driven to rotate by a motor through a triangle belt.
At present, the concentrate quality of a centrifugal separator is difficult to accurately guarantee. The quality of the ore concentrate is judged and adjusted mainly by an operator after elutriating the ore concentrate, if the quality of the ore concentrate is low, the rinsing water of the centrifugal machine is enlarged, the ore pulp is washed by the larger rinsing water in the centrifugal machine, ore particles with light specific gravity are elutriated more, and ore particles with high specific gravity are left, so the grade of the ore concentrate is improved. The reverse is true. And (4) elutriating the concentrate once by an operator at regular intervals, and adjusting the rinsing water quantity according to the elutriation result to ensure that the quality of the concentrate is in a specified range. The quality of tin concentrate is affected by the influence of the components of ore feeding pulp, the proficiency of operators and the responsibility of the operators, so that the quality of the tin concentrate is uneven, the vertical variation range is large, and the influence on product sale of enterprises and the economic benefit are large.
In the mineral separation production, the grade analyzer is applied to the flotation operation, and is only used for rapidly detecting the grade of each element of ore pulp on line, and then an operator adjusts the flotation according to detected data, wherein the adjustment is manual adjustment and non-automatic adjustment. The grade analyzer is not applied to automatic adjustment of the concentrate grade of the centrifugal separator, so that the quality of the concentrate can reach the standard.
In recent years, the domestic patent database discloses the technical reports of similar ore dressing centrifuges:
[ application No. ] ZL2018107186828, [ name ] mineral processing centrifuge is adopted to ore deposit, [ publication No. ] CN108787186A, discloses that a mineral processing centrifuge is adopted to ore deposit, including the bearing platform, the lower fixed surface of bearing platform installs damping spring, the inboard of centrifuge bowl shell is provided with inhales the sound cotton, the one end fixed mounting of driving plate has the protective cover, the inboard of first pivot is rotated and is connected with electronic hydraulic stem, the preceding fixed surface of centrifuge bowl shell installs SE300 control panel, nevertheless because the device can't be to the automatically regulated of concentrate grade, there is the unstable problem of concentrate quality.
