Description
Technical Field
The invention relates to the technical field of mining, in particular to a method and a device for sorting magnetite powder and electronic equipment.
Background
With the gradually increasing requirement of clean utilization of coal, the role of a coal preparation plant is more and more prominent, and at present, the main separation processes of the coal preparation plant are divided into two types, namely dry separation and wet separation, wherein the dry separation is still in the research and development test stage, so that the mainstream separation process is still the wet separation, and the wet separation is mainly dense medium separation. The dense-medium coal separation process mainly separates by a mixed suspension of magnetite powder, water and coal slime, realizes the control of the density of the suspension by controlling the amount of magnetite and coal slime, and removes and recycles the magnetite powder because the magnetite powder enters a concentrate coal product to seriously affect the quality of the concentrate coal and cause a large amount of consumption of the magnetite powder to increase the cost. The recovery of magnetite powder is usually accomplished by means of a magnetic separator. The magnetic separator mainly depends on the strong magnetic field in the roller to recover magnetite in dilute media, and a permanent magnet is adopted to provide a magnetic field. The loss of magnetite in the coal preparation plant is mainly as follows: the removal of the medium-removing sieve product accounts for 30%, the loss of the magnetic separation tailings accounts for 60%, and the loss of other tailings accounts for 10%, so that the management of magnetite powder lost from the tailings of the magnetic separator needs to be enhanced.
The magnetite powder is a powdery product obtained by crushing, grinding, grading and drying the mined magnetite ore, and impurities are added in the mining process and the subsequent processing process or the magnetism of the magnetite powder is weakened due to the action of oxygen in the using process, so that the magnetite powder is a mixture of ferroferric oxide, other weak magnetic substances and non-magnetic substances. The magnetic separator in the coal preparation plant is mainly used for adsorbing ferroferric oxide and other weak magnetic substances under the action of a magnetic field, the ferroferric oxide and other weak magnetic substances contain iron elements, and the grade of the ferroferric oxide and other weak magnetic substances is used for representing the iron content of the magnetite powder. The grade of the iron ore refers to the mass fraction of iron element in the iron ore, and is generally referred to as the iron content. For example, the grade of iron ore is 62, which means that the mass fraction of iron element is 62%. Magnetite (Fe 3O4 as the major component) with a theoretical maximum grade of 72.4%, feO =31%, fe2O3=69%. It is known that the higher the grade, the higher the iron content, the lower the magnetic field strength required for adsorption, and the lower the grade, the stronger the magnetic field strength required for recovery, so the grade of magnetite powder directly affects the recovery rate of magnetite by the magnetic separator. The working condition inspection of the magnetic separator mainly adopts a process effect evaluation method of magnetic separation equipment of a coal separation plant at present. The inspection method has the advantages that the method is flaky, the magnetite powder is considered to have completely consistent characteristics and all consistent grades, theoretically all magnetite powder should be recycled, and the method is not in line with the field reality. Further analysis revealed that, as a complex mixture (similar to coal) mainly composed of magnetite powder, the magnetite powder having a high grade and a low grade, both of which are present after infinite refinement, is present in all of magnetite powder from high to low. In the actual separation and recovery process, the tailings with the element grade higher than a certain value are recovered, and the tailings with the element grade lower than the element grade value enter the tailings.
The concentrate yield of the magnetic separator is related to the working conditions (feed flow, feed concentration, feed particle size, operation process, magnetic declination, magnetic pole arrangement and the like) of the magnetic separator, the magnetic field intensity of the magnetic separator and the characteristics of magnetite powder. At present, coal preparation plants deeply research the working conditions of magnetic separators and manage and control the magnetic separators in a reasonable mode, but generally select a fixed magnetic field strength due to the lack of effective and reasonable management and control measures for the magnetic field strength, for example, 1500Gs permanent magnet separators are used for recovering various magnetite powder, and factors of uncontrollable magnetic field strength and uncertain applicability exist.

Detailed Description
The embodiment of the invention provides a method and a device for sorting magnetite powder and electronic equipment.
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, shall fall within the scope of protection of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a method for sorting magnetite powder. The method may specifically comprise the steps of:
s01, acquiring a corresponding relation between sorting parameters of each preset type of magnetite powder to be sorted by a preset experimental method; wherein the sorting parameters of the preset categories include: a sorting magnetic field strength and a yield of a sorting magnetic field strength interval corresponding to the sorting magnetic field strength.
Firstly, the magnetite powder to be selected is dried and weighed, and is stored for later use, and a preset number of samples are selected from the magnetite powder.
And (3) carrying out a sorting experiment on the sample by a preset experimental method, and recording each sorting parameter generated in the sorting experiment process. And according to the experimental result, calculating to obtain the intercrossed corresponding relation among the sorting parameters.
The sorting parameters at least comprise sorting magnetic field strength and a yield of a sorting magnetic field strength interval corresponding to the sorting magnetic field strength.
Further, the sorting parameters are various, and the embodiment of the present invention only gives an illustration of one of the sorting parameters. The sorting parameters further include: sorting element grade, concentrate yield, concentrate grade, tailing yield and tailing grade.
The sorting magnetic strength is a selected magnetic field strength.
The separation magnetic field intensity interval is a magnetic field intensity interval corresponding to the separation magnetic field intensity, and the interval can be set according to actual requirements. The embodiment of the present invention is given only one of the illustrations.
The sorting magnetic field intensity interval corresponding to the sorting magnetic field intensity is from the sorting magnetic field intensity minus 0.1KGs to the sorting magnetic field intensity plus 0.1KGs.
The sorting magnetic field intensity interval is an interval of plus or minus 0.1KGs with the sorting magnetic field intensity as the center, and can be simply expressed as +/-0.1 of the sorting magnetic field intensity.
The yield of the separation magnetic field strength interval is the concentrate yield when the magnetic field strength is the separation magnetic field strength interval, which is equivalent to subtracting the concentrate yield of the minimum magnetic field strength from the concentrate yield of the maximum magnetic field strength in the separation magnetic field strength interval.
The elementary grade is the grade of magnetite powder obtained by crushing and grinding magnetite. The grade of the sorting element is that the grade of the sorting element is taken as a boundary, and the magnetite powder with the grade higher than the grade of the sorting element can be recovered during sorting.
The concentrate yield is the proportion of the magnetite powder recovered after separation in the total amount of the magnetite powder under the corresponding magnetic field strength.
The concentrate grade is the average grade of the magnetite powder recovered after separation under the corresponding magnetic field strength.
The tailing yield is the proportion of the remaining magnetite powder in the total magnetite powder amount after the separation under the corresponding magnetic field strength.
The grade of the tailings is the average grade of the magnetite powder remained after the separation under the corresponding magnetic field intensity.
And S02, obtaining the sorting magnetic field intensity corresponding to the sorting parameter requirement and the yield of the sorting magnetic field intensity interval from the corresponding relation among the sorting parameters of all the preset types according to the preset sorting parameter requirement.
And presetting the requirement of separation parameters when the magnetite powder to be separated is separated.
The sorting parameter requirements can be set according to actual requirements, and can be any set sorting element grade, concentrate yield, concentrate grade, tailing yield, tailing grade or sorting magnetic field intensity.
The sorting parameter requirement can be a set sorting element grade, and the magnetite powder with the grade higher than the set sorting element grade in the magnetite powder to be sorted is required to be recycled in the sorting process.
The sorting parameter requirement may be a set concentrate yield, and the concentrate yield recovered in the sorting process is required to reach the set concentrate yield.
The separation parameter requirement can be a set concentrate grade, and the concentrate grade recovered in the separation process is required to reach the set concentrate grade.
The sorting parameter requirement may be a set tailing yield, and the remaining tailing yield in the sorting process is required to reach the set tailing yield.
The separation parameter requirement can be a set tailing grade, and the remaining tailing grade in the separation process is required to reach the set tailing grade.
The sorting parameter requirement can be a set sorting magnetic field intensity, and then the magnetic field intensity of the magnetic separator in the sorting process is required to be the sorting magnetic field intensity.
In practice, the sorting parameter requirement may be a set value interval of any sorting parameter, or a plurality of sorting parameters may be set at the same time, and is not specifically limited herein, but for the sake of simplicity, the sorting parameter requirement is exemplified as a set value of any sorting parameter in the following embodiments.
After the sorting parameter requirements are determined, values of other sorting parameters corresponding to the sorting parameter requirements can be respectively searched and obtained through the obtained corresponding relations among the sorting parameters. Specific examples are as follows:
if the sorting parameter requirement is set concentrate yield, the sorting element grade, the concentrate grade, the tailing yield, the tailing grade, the sorting magnetic field intensity and the yield of the sorting magnetic field intensity interval corresponding to the set concentrate yield are obtained through corresponding relation query;
if the sorting parameter requirement is a set concentrate grade, the sorting element grade, the concentrate yield, the tailing grade, the sorting magnetic field intensity and the yield of the sorting magnetic field intensity interval corresponding to the set concentrate grade are obtained through corresponding relation query;
if the sorting parameter requirement is the set tailing grade, the sorting element grade, the concentrate yield, the concentrate grade, the tailing yield, the sorting magnetic field intensity and the yield of the sorting magnetic field intensity interval corresponding to the set tailing grade are obtained through corresponding relation query;
and if the sorting parameter requirement is the set sorting magnetic field intensity, the sorting element grade, the concentrate yield, the concentrate grade, the tailing yield, the tailing grade and the yield of the sorting magnetic field intensity interval corresponding to the set sorting magnetic field intensity are obtained through corresponding relation query.
And S03, performing the sorting operation of the magnetite powder to be sorted according to the selectable grade corresponding to the yield of the sorting magnetic field intensity interval and the sorting magnetic field intensity.
As can be seen from the above-described embodiment, the yield of the sorting magnetic field strength interval is the yield of the magnetic field strength interval in the vicinity of the sorting magnetic field strength, and a larger value indicates a poorer selectivity, while a smaller value indicates a better selectivity. Therefore, the selectable grade of the magnetite powder to be sorted can be obtained according to the preset and divided selectable grade and the yield of the sorting magnetic field intensity interval corresponding to the sorting parameter requirement. And meanwhile, according to the separation magnetic field strength corresponding to the separation parameter requirement, determining the magnetic field strength of the magnetic separator when the magnetite powder to be separated is separated, and starting the separation operation of the magnetite powder to be separated.
According to the technical scheme provided by the embodiment of the invention, the embodiment of the invention obtains the corresponding relation among the sorting parameters of each preset type of the magnetite powder to be sorted by a preset experimental method; wherein the sorting parameters of the preset categories include: a sorting magnetic field strength and a yield of a sorting magnetic field strength interval corresponding to the sorting magnetic field strength; according to preset sorting parameter requirements, obtaining sorting magnetic field intensity corresponding to the sorting parameter requirements and a yield of sorting magnetic field intensity intervals from the corresponding relation among the sorting parameters of the preset types; and carrying out the sorting operation of the magnetite powder to be sorted according to the selectable grade corresponding to the yield of the sorting magnetic field intensity interval and the sorting magnetic field intensity, so that the adaptation of the magnetic field intensity of the magnetic separator to the magnetite powder to be sorted is realized, and the flexible adjustment can be carried out according to the actual requirement.
As shown in fig. 2, further, the step S01 includes:
and S011, performing a separation experiment on the magnetite powder to be separated according to a preset magnetic field intensity interval division rule, and obtaining the concentrate yield, the concentrate grade, the tailing yield and the tailing grade of each magnetic field intensity interval.
According to a preset experimental method for magnetite powder, each of the sorted magnetic field strengths is set in advance, and magnetic field strength intervals are divided, for example, the set sorted magnetic field strengths are 800Gs,900Gs,1000Gs,1100Gs,1200Gs,1400Gs,1600Gs,1800Gs,2000Gs,2200Gs and 250Gs, respectively, so that the divided magnetic field strength intervals are <800Gs,800-900Gs,900-1000Gs,1000-1100Gs, 1100-0Gs, 1200-1401200 Gs,1400-1600Gs,1600-1800Gs,1800-2000Gs,2000-2200Gs,2200-2500Gs and 2500Gs. The division of the magnetic field strength interval may be performed according to actual needs, but for the sake of simplicity, the division is exemplified in the following embodiments. The magnetic field intensity interval can also be expressed as <0.8,0.8-0.9,0.9-1.0,1.0-1.1,1.1-1.2,1.2-1.4,1.4-1.6,1.6-1.8,1.8-2.0,2.0-2.2,2.2-2.5, >2.5 in KGs.

| interval of magnetic field intensity | Yield of concentrate | Grade of concentrate |
| <800 | β1 | TFe1 |
| 800-900 | β2-β1 | (TFe2*β2-TFe1*β1)/(β2-β1) |

The sorting parameters for each magnetic field strength interval were thus recorded as shown in table 3:
TABLE 3
For the sake of simplicity, the following examples are given by way of example of the record of Experimental method 2.
And S012, obtaining the corresponding relation among the sorting parameters of each preset type through a preset calculation method according to the concentrate yield, the concentrate grade, the tailing yield and the tailing grade of each magnetic field intensity interval.
According to the concentrate yield, the concentrate grade, the tailing yield and the tailing grade of each magnetic field intensity interval obtained through the experiment, the values of other separation parameters can be obtained through calculation, and the corresponding relation among the separation parameters is obtained, namely the corresponding relation among the concentrate yield, the concentrate grade, the tailing yield, the tailing grade, the separation magnetic field intensity and the yield of the separation magnetic field intensity interval.
As shown in fig. 3, step S012 further includes:
step S0121, drawing a grade characteristic curve, a concentrate accumulation curve, a tailing accumulation curve, a field intensity curve and a yield curve of a sorting magnetic field intensity interval in the same coordinate system through a preset calculation method according to the concentrate yield, the concentrate grade, the tailing yield and the tailing grade of each magnetic field intensity interval; wherein the content of the first and second substances,

the tailing accumulation curve is used for representing the corresponding relation between the tailing grade and the tailing yield;
the field intensity curve is used for representing the corresponding relation between the sorting magnetic field intensity and the yield of the concentrate;
and the yield curve of the sorting magnetic field intensity interval is used for representing the corresponding relation between the corresponding sorting magnetic field intensity and the yield of the sorting magnetic field intensity interval.
According to table 3, the concentrate yield, the concentrate grade, the tailing yield, the tailing grade, and the yield of the separation magnetic field intensity interval corresponding to each separation magnetic field intensity can be obtained by a preset calculation method, as shown in table 4:
TABLE 4
According to the corresponding relation among the sorting parameters obtained by the tables, respectively drawing a grade characteristic curve, a concentrate accumulation curve, a tailing accumulation curve, a field intensity curve and a yield curve of a sorting magnetic field intensity interval in the same coordinate system.
The coordinate system selects a main abscissa X as grade, a secondary abscissa X as magnetic field intensity, a main ordinate Y as tailing yield and a secondary ordinate Y as concentrate yield.
The grade characteristic curve is used for representing the corresponding relation between the grade of the sorting element and the yield of the concentrate;
the concentrate cumulative curve is used for representing the corresponding relation between the concentrate grade and the concentrate yield;
the tailing accumulation curve is used for representing the corresponding relation between the tailing grade and the tailing yield;
the field intensity curve is used for representing the corresponding relation between the sorting magnetic field intensity and the concentrate yield;
and the yield curve of the sorting magnetic field intensity interval is used for representing the corresponding relation between the corresponding sorting magnetic field intensity and the yield of the sorting magnetic field intensity interval.
The sorting parameter correspondence of each curve obtained from each table is shown in table 5:
TABLE 5
Wherein, according to the fact that the highest grade of magnetite powder can reach 72.4, when the adding grade reaches 72.4 in the first row of the element grade curve and the concentrate accumulation curve, the concentrate yield approaches 0.
Further, the step S02 includes:
and S021, searching for the sorting magnetic field intensity corresponding to the sorting parameter requirement and the yield of the sorting magnetic field intensity interval from the coordinate system according to a preset sorting parameter requirement.
Through the five curves drawn in the same coordinate system, various sorting parameters corresponding to preset sorting parameter requirements can be inquired and obtained, wherein the sorting parameters comprise sorting magnetic field intensity and yield of sorting magnetic field intensity intervals.
Thereby, according to the inquired sorting magnetic field intensity and the yield of the sorting magnetic field intensity interval, the sorting operation of the magnetite powder to be sorted is started.
According to the technical scheme provided by the embodiment of the invention, the embodiment of the invention obtains the corresponding relation among the sorting parameters of each preset type of the magnetite powder to be sorted by the preset experimental method, and draws a grade characteristic curve, a concentrate accumulation curve, a tailing accumulation curve, a field intensity curve and a yield curve of a sorting magnetic field intensity interval under the same coordinate system, so that the sorting magnetic field intensity corresponding to the sorting parameter requirement and the yield of the sorting magnetic field intensity interval are found out from the coordinate system, the magnetic field intensity of the magnetic separator is adapted to the magnetite powder to be sorted, and the magnetic field intensity of the magnetic separator can be flexibly adjusted according to the actual requirement.
Based on the above embodiment, further, the step S03 includes:
and step S031, determining the magnetic field intensity of the magnetic separator during the separation operation of the magnetite powder to be separated according to the magnetic field intensity.
And S032, determining the selectable grade of the magnetite powder to be selected according to the yield of the separation magnetic field intensity interval and the corresponding relationship between the yield and the selectable grade of each pre-stored separation magnetic field intensity interval, and adjusting the separation operation process according to the selectable grade.
And after the sorting magnetic field strength corresponding to the sorting parameter requirement and the yield of the sorting magnetic field strength interval are searched from the coordinate system, setting the magnetic field strength of the magnetic separator according to the sorting magnetic field strength.
The selectable level is divided in advance, and a specific division rule can be set according to actual needs, and the embodiment of the present invention only gives an example as follows, as shown in table 6.
| Yield of sorted magnetic field strength intervals | Level of selectability |
| Less than or equal to 3 | Is easy to select |
| 3.0-6.0 | Medium selective |
| 6.0-9.0 | Is difficult to select |
| 9.0-12.0 | Difficult to select |
| >12.0 | Is extremely difficult to select |
TABLE 6
Therefore, the selectable grade of the magnetite powder to be selected can be determined according to the magnetic field intensity separation section, and the separation process of the magnetite powder to be selected can be adjusted according to the difficulty degree of the selectable grade. If the ore powder is difficult to separate, the pretreatment process of the magnetite powder can be correspondingly increased, so that the selectivity of the magnetite powder is reduced, and the separation efficiency is improved.
Further, after the step S03, the method further includes:
s04, calculating actual separation parameters of the magnetite powder to be separated according to the separation result of the magnetite powder to be separated;
and S05, comparing the actual sorting parameters with theoretical sorting parameters which are obtained by searching according to the corresponding relation among the sorting parameters of all the preset types and correspond to the sorting parameter requirements, and evaluating the working condition of the magnetic separator.
After the magnetite powder to be sorted is sorted according to the searched sorting magnetic field intensity and the yield of the sorting magnetic field intensity interval, actual sorting parameters of the magnetite powder to be sorted, such as actual concentrate yield, actual concentrate quality, actual tailing yield, actual tailing quality and the like, are obtained through measurement.
And comparing the actual separation parameters with the theoretical separation parameters obtained by inquiry, thereby obtaining the working condition of the magnetic separator. For example, the ratio of the actual concentrate yield to the theoretical concentrate extraction can be taken as the efficiency value of the magnetic separator.
As can be seen from the technical solutions provided by the embodiments of the present invention, in the embodiments of the present invention, the magnetic field strength of the magnetic separator during the sorting operation of the magnetite powder to be sorted is determined according to the sorting magnetic field strength, the selectable grade of the magnetite powder to be sorted is determined according to the yield of the sorting magnetic field interval and the corresponding relationship between the yield of each sorting magnetic field interval and the selectable grade, the sorting operation process is adjusted according to the selectable grade, and the working condition of the magnetic separator is evaluated by comparing the actual sorting parameters with the theoretical sorting parameters according to the sorting result. The magnetic field intensity of the magnetic separator is adapted to the magnetite powder to be separated, and the magnetic field intensity can be flexibly adjusted according to actual requirements.
One specific example is given below:
the correspondence of the sorting parameters obtained according to the experimental method in advance is shown in table 7:
TABLE 7
