Description

Technical Field

[0001] The present invention relates to the technical field of coal mine processing, and in particular to a magnetic separator for coal mine processing and a use method thereof. Background Art

[0002] At present, in the coal mining industry, the collected coal generally needs to be further processed. Coal processing is the general term for a series of scientific research, technological development and processing and utilization carried out to make the mined coal and its associated minerals fully and effectively play the role of energy and raw materials, meet the needs of various users, and protect the natural environment.

[0003] At present, in the process of coal mining, since the coal raw materials contain a large amount of magnetic minerals, it is necessary to use magnetic separation equipment to magnetically separate the magnetic minerals from the coal raw materials. Common magnetic separators are mostly composed of magnetic separation bins, driving mechanisms, magnetic separation drums and magnetic poles. The magnetic minerals are adsorbed by the magnetic poles, then move with the magnetic separation drum, and finally discharged, thereby realizing the magnetic separation processing of coal raw materials.

[0004] However, the above-mentioned magnetic separator generally directly puts the coal raw materials into the magnetic separation bin, and then adsorbs them through the magnetic poles. Since the magnetic separation bin does not have a structure to oscillate and shake the coal raw materials, when facing some powdered coal raw materials, due to the agglomeration of the coal raw materials themselves and the inability of the coal raw materials to get closer to the magnetic separation drum, insufficient magnetic separation may occur. For this reason, we propose a magnetic separator for coal processing and a method for using the same. Summary of the invention

[0005] The object of the present invention is to provide a magnetic separator for coal processing and a method of using the same. By setting up a magnetic separation mechanism and utilizing a toggle plate, a positive reset assembly, a flip reset assembly and an extrusion toggle assembly, the agglomerated coal raw materials can be broken up and the coal raw materials can be pushed toward a drum, thereby producing a good magnetic separation effect.

[0040] In a second aspect, the present invention provides a method for using a magnetic separator for coal mining processing, and implements a magnetic separator for coal mining processing as described above. The specific steps of the method are as follows:

[0041] Step 1: Coal raw materials are put into the feeding assembly, and the driving mechanism drives the drum to rotate. At the same time, the magnetic pole mechanism works and adsorbs the magnetic materials in the coal raw materials, so that the magnetic materials are adsorbed on the outer surface of the drum and move with the drum until they are at the magnetic material discharge port. Since there is no magnetic pole mechanism adsorption, the magnetic materials are discharged from the magnetic material discharge port, and the non-magnetic materials are discharged from the non-magnetic material discharge port;

[0042] Step 2: Due to the rotation of the drum, the extrusion and toggle assembly cooperates with the toggle plate to squeeze the flip reset assembly and the forward reset assembly, so that the toggle plate alternately retreats, resets, and then flips, thereby vibrating and shaking the coal raw materials to disperse them, and at the same time, the coal raw materials are pushed toward the drum;

[0043] Step 3: According to the discharge amount of the magnetic material, the driving mechanism adaptively adjusts the drum speed.

[0044] Preferably, the method for adaptively adjusting the rotation speed of the drum by the driving mechanism comprises the following specific steps:

[0045] Step 1: Weigh and obtain the weight of the magnetic material discharged from the magnetic material discharge port;

[0046] Step 2: Analyze and process the weight information data of the magnetic material discharged from the magnetic material discharge port, and control the driving mechanism based on the adaptive model;

[0047] Step 3: The driving mechanism is switched in a stepped speed power mode;

[0048] The specific contents of the adaptive model are as follows:

[0049] The stepped rotational speed power mode is divided into a first-stage rotational speed power, a second-stage rotational speed power, and a third-stage rotational speed power. The switching threshold between the first-stage rotational speed power and the second-stage rotational speed power is set as Ya, and the switching threshold between the second-stage rotational speed power and the third-stage rotational speed power is set as Yb. The total weight information data of the magnetic materials collected within the time period T is collected by the weighing module and recorded as W. Subsequently, the total weight information data W of the magnetic materials is transmitted to the analysis and processing module. The analysis and processing module substitutes the most recent three W values into the influence formula and obtains the influence factor X. When the driving mechanism is at the first-stage rotational speed power, the magnitude relationship between X*N and Ya is judged. If X*N is greater than or equal to Ya, the rotational speed is switched from the first stage to the second-stage rotational speed power. If X*N is less than Ya, the first-stage rotational speed power is maintained. When the driving mechanism is at the second-stage rotational speed power, the magnitude relationship between X*N and Yb is judged. If X*N is greater than or equal to Yb, the rotational speed is switched from the second-stage rotational speed power to the third-stage rotational speed power. If X*N is less than Yb and greater than Ya, the second-stage rotational speed power is maintained. If X*N is less than or equal to Ya, the rotational speed is switched from the second-stage rotational speed power to the first-stage rotational speed power. When the driving mechanism is at the third-stage rotational speed power, the magnitude relationship between X*N and Yb is judged. When X*N is greater than or equal to Yb, the third-stage rotational speed power is maintained. When X*N is less than Yb, the rotational speed is switched from the third-stage rotational speed power to the second-stage rotational speed power, and the value range of N is 1.2 to 1.5.

[0050] Preferably, the influence formula is:

[0051] X = { (W n / T n * 0.5) + (W n-1 / T n-1 * 0.3) + (W n-2 / T n-2 * 0.2)} / 3;

[0052] Where W n is the total weight information data of the magnetic materials collected by the weighing module within T, W n is the total weight information data of the magnetic materials collected by the weighing module within the previous time period T n-1 before T, and W n is the total weight information data of the magnetic materials collected by the weighing module within the previous time period T n-1 before that T. n-2 is the total weight information data of the magnetic materials collected by the weighing module within the previous time period T n-1 before that T. n-2 is the total weight information data of the magnetic materials collected by the weighing module within that T.

[0053] The technical effects and advantages of the present invention:

[0054] (1) By feeding materials into the silo component, when the coal mine raw materials enter the interior of the silo component, at this time, the oscillating and jittering structure will undergo front-back jittering and a certain-angle flipping phenomenon, thereby dispersing the agglomerated coal mine raw materials. At the same time, the coal mine raw materials will be deflected towards the drum. Meanwhile, the driving mechanism drives the drum to rotate, and at the same time, the magnetic pole mechanism starts to adsorb the magnetic materials in the coal mine raw materials, thus realizing magnetic separation of the coal mine raw materials. This design uses the oscillating and deflecting structure to disperse the coal mine raw materials and deflect them towards the drum and the magnetic pole mechanism, thereby achieving a good magnetic separation effect. Among them, the driving mechanism, the drum, and the magnetic pole mechanism can all be obtained from the prior art and will not be elaborated here;

[0055] (2) By setting the shielding component, when the deflecting plate is inside the silo, it can contact the inner wall surface of the silo through the sealing sleeve. At the same time, the support strips made of rubber support the sealing sleeve, so that the sealing sleeve fully fits the inner wall surface of the silo, making the deflecting plate relatively sealed with the silo, thus preventing the coal mine raw materials from escaping through the gap between the side plate and the silo;

[0056] (3) By setting the adaptive adjustment system, according to the magnetic materials produced by the magnetic separation of the magnetic separator, the rotation speed of the driving mechanism driving the drum is adjusted. It can increase the rotation speed when the magnetic materials increase, thereby avoiding excessive adsorption of magnetic materials on the local outer surface of the drum, resulting in a poor adsorption magnetic separation effect. It can also reduce the rotation speed when the magnetic materials decrease, thereby achieving the purpose of reducing load and energy consumption. Brief Description of the Drawings

[0071] Furthermore, the oscillating and shaking structure includes: a toggle plate 6, which is arranged between the roller 3 and the silo 501, and a feeding assembly 12 is arranged above the toggle plate 6; a shielding assembly 7, which is fixedly connected to both sides of the toggle plate 6; a positive reset assembly 11, which is hinged to the side of the toggle plate 6; a flip reset assembly 9, which is connected to one end of the positive reset assembly 11, and a support plate 8 is fixedly connected between the flip reset assembly 9 and the positive reset assembly 11, and the support plate 8 is fixedly connected to the inner wall surface of the raised cylinder 504; an extrusion toggle assembly 10, which is arranged between the roller 3 and the toggle plate 6; the roller 3 is driven to rotate by the driving mechanism 2, and the toggle plate is made to rotate by the cooperation between the extrusion toggle assembly 10 and the toggle plate 6. 6 starts to move backward, thereby squeezing the positive reset component 11, and then the positive reset component 11 drives the toggle plate 6 to reset, and at the same time slightly squeezes the flip reset component 9, so that the toggle plate 6 is slightly flipped, and then the flip reset component 9 drives the toggle plate 6 to reset. At this time, the toggle plate 6 will alternately move backward, then reset, and slightly flip, and then reset, so that the toggle plate 6 will vibrate and shake and toggle, so that the agglomerated coal raw materials are broken up, and at the same time, the coal raw materials are pushed toward the drum 3, and the squeezing of the toggle component 10 will also cause the toggle plate 6 to deflect to a large extent, so that the toggle plate 6 pushes the coal raw materials toward the drum 3, so that the coal raw materials are close to the drum 3, thereby producing a good adsorption magnetic separation effect and avoiding insufficient magnetic separation.

[0072] Further, the toggle plate 6 includes: a main board 601, the main board 601 is fixedly connected to the end of the positive reset component 11, and the two sides of the main board 601 are fixedly connected to the side plates 602; an arcuate side 603 and a sloped side 604, and the side of the side plate 602 close to the roller 3 is sequentially provided with an arcuate side 603 and a sloped side 604 from top to bottom; the extrusion toggle component 10 includes: a plurality of oscillation protrusions 1001, and the plurality of oscillation protrusions 1001 are fixedly connected to one side of the arcuate side 603; a plurality of extrusion blocks 1002, and the plurality of extrusion blocks 1002 are fixedly connected to the outer surface of the roller 3, and the side of the extrusion block 1002 close to the toggle plate 6 is composed of an extrusion bevel 10021 and a peak and valley side 10022 located on one side of the extrusion bevel 10021, and the extrusion block 1002 is integrally formed; a flip tooth 1003, and the flip tooth 1003 is fixedly connected to one side of the top of the arcuate side 603;The clockwise rotation of the drum 3 drives the equally spaced extrusion blocks 1002 to squeeze the oscillation protrusions 1001, so that the toggle plate 6 moves backward.

The switching threshold between the first-stage rotational speed power and the second-stage rotational speed power is set as Ya, and the switching threshold between the second-stage rotational speed power and the third-stage rotational speed power is set as Yb. The total weight information data of the magnetic materials collected within the time period T is collected by the weighing module and recorded as W. Subsequently, the total weight information data W of the magnetic materials is transmitted to the analysis and processing module. The analysis and processing module substitutes the most recent three W values into the influence formula and obtains the influence factor X. When the driving mechanism 2 is at the first-stage rotational speed power, the magnitude relationship between X*N and Ya is judged. If X*N is greater than or equal to Ya, the rotational speed is switched from the first stage to the second-stage rotational speed power. If X*N is less than Ya, the first-stage rotational speed power is maintained. When the driving mechanism 2 is at the second-stage rotational speed power, the magnitude relationship between X*N and Yb is judged. If X*N is greater than or equal to Yb, the rotational speed is switched from the second stage to the third-stage rotational speed power. If X*N is less than Yb and greater than Ya, the second-stage rotational speed power is maintained. If X*N is less than or equal to Ya, the rotational speed is switched from the second stage to the first stage. When the driving mechanism 2 is at the third-stage rotational speed power, the magnitude relationship between X*N and Yb is judged. When X*N is greater than or equal to Yb, the third-stage rotational speed power is maintained. When X*N is less than Yb, the rotational speed is switched from the third stage to the second stage, and the value range of N is 1.2 to 1.5.

[0087] Further, the influence formula is:

[0088] X = { (W n / T n * 0.5) + (W n-1 / T n-1 * 0.3) + (W n-2 / T n-2 * 0.2)} / 3;

[0089] where W n is the total weight information data of the magnetic materials collected by the weighing module within T, W n is the total weight information data of the magnetic materials collected by the weighing module within the previous time period T before T, W n-1 is the total weight information data of the magnetic materials collected by the weighing module within the previous time period T before T n before the previous time period T n-1 before T, and W n-2 is the total weight information data of the magnetic materials collected by the weighing module within T n-1 before the previous time period T n-2The internal weighing module collects the total weight information data of the magnetic material; by grabbing the total weight information data W of the magnetic material collected by the weighing module in the most recent three times within the T time period each time, and then substituting it into the adaptive model, and the influencing factor X can iterate following the update of each W, which can maintain the validity of the data. Thus, the driving mechanism 2 is adjusted according to the magnetic material separated by the magnetic separator to drive the rotation speed of the roller 3. When the magnetic material increases, the rotation speed can be increased to avoid excessive adsorption of magnetic material on the local outer surface of the roller 3, resulting in a poor adsorption and separation effect. When the magnetic material decreases, the rotation speed can be reduced to achieve the purpose of reducing the load and its energy consumption.
