Description

Technical Field

[0001] The invention relates to the technical field of coal gangue processing, in particular to an intelligent coal gangue selecting system. Background Art

[0002] A large amount of coal gangue is produced during the production and processing of coal. The large amount of coal gangue storage has brought various negative impacts on the ecological environment of the mining area, such as occupying land, polluting the environment, and destroying the landscape. However, coal gangue is not a simple waste, but a resource that can be used to replace coal for power generation, or replace clay for building materials, etc.

[0003] To reuse coal gangue, it is necessary to decarbonize it first. Generally, mines use jigs to separate coal blocks and coal gangue. Traditional jigs use water as the dressing medium and use the difference in specific gravity of the selected minerals and gangue. Water flows through the screen plate into the jig chamber, causing the bed to rise and become slightly loose. The dense particles enter the bottom layer due to the local pressure and sedimentation velocity, and the small particles move to the upper layer to achieve separation. The machine can separate the gangue and coal blocks without sticking to each other, but in reality, most of the gangue and coal blocks are stuck to each other. Generally, the coal seam is wrapped around the outside of the gangue, so that they cannot be separated by the specific gravity of the gangue. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides an intelligent gangue separation system for coal gangue, which solves the following problems: the traditional jig uses water as a mineral separation medium, and uses the difference in specific gravity between the selected mineral and the gangue. The water flows into the jig chamber through the screen plate, so that the bed layer rises and becomes slightly loose. The particles with high density enter the bottom layer due to the large local pressure and sedimentation velocity, and the particles with low density move to the upper layer to achieve separation. The machine can separate the coal gangue and the coal block without sticking to each other. However, in the display, most of the coal gangue and the coal block are stuck to each other. Generally, the coal gangue wraps the coal layer outside, so that the technical problem of separation cannot be achieved by the specific gravity of the gangue.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] The technical solution adopted by the present invention to solve the technical problem is: an intelligent gangue selection system for coal gangue, comprising:

[0007] Workbench;

[0009] The crushing assembly includes a sliding groove, a sliding column, a supporting spring, a curved cover and a crushing head. The sliding groove is fixedly connected to the first crushing roller, and a sliding column is slidably connected in the sliding groove. One end of the sliding column close to the first crushing roller is inside the sliding groove, and one end of the sliding column close to the first crushing roller is fixedly connected to one end of a supporting spring, and the other end of the supporting spring is fixedly connected to the bottom of the sliding groove, that is, the outer wall of the first crushing roller. One end of the sliding column away from the first crushing roller extends out of the sliding groove and is fixedly connected to the convex surface of the curved cover, and a crushing head is fixedly connected to the concave surface of the curved cover, and a push rod is fixedly connected to the sliding groove, and the push rod cooperates with the curved cover, and the curved cover is elastic metal.

[0010] Preferably, the transport component is below the crushing component, and the transport component includes a slide rail, the workbench is provided on one side of the slide rail, the workbench is fixedly connected to the support legs, rollers are provided at both ends of the workbench, the rollers are rotatably connected to the support legs, a conveyor belt is nested on the roller, teeth are fixedly connected to both sides of the roller, the teeth are meshed with tooth holes, the tooth holes are provided on the connecting strip, the connecting strip is fixedly connected to both sides of the conveyor belt, a jig is provided below the end of the conveyor belt, baffles are provided on both sides of the conveyor belt, the baffles are fixedly connected to the workbench, one end of the baffle away from the jig is fixedly connected to the slide rail, the discharge port of the slide rail is above the conveyor belt, and the slide rail does not contact the conveyor belt

[0011] Preferably, the rolling assembly is fixedly connected to the workbench by a bracket, and the rolling assembly includes the first crushing roller, which is fixedly connected to the workbench through the bracket, a second crushing roller is provided on one side of the first crushing roller, and the second crushing roller is also fixedly connected to the workbench by the bracket, a first gear is fixedly connected to one end of the first crushing roller, the first gear is meshed with a main gear, the main gear is meshed with the second gear, the second gear is fixedly connected to one end of the second crushing roller, the first crushing roller and the second crushing roller are both staggered with the crushing assembly, the first crushing roller and the second crushing roller are above the conveyor belt, and the gap between them can be used for coal gangue, the rotating shaft is fixedly connected to the main gear, one end of the belt is nested on the rotating shaft, the other end of the belt is rotatably connected to the turntable, and the turntable is fixedly connected to one side of the drum.

[0012] Preferably, the flip assembly is arranged below the conveyor belt, the flip assembly is arranged on the workbench, the flip assembly comprises a wave surface, the wave surface is arranged on the workbench, and the conveyor belt is closely attached to the wave surface.

[0013] (1) In the intelligent gangue sorting system described in the present invention, the number of teeth on the first gear is greater than the number of teeth on the second gear, so the rotation speed of the first crushing roller is slower than the rotation speed of the second crushing roller. At the same time, the crushing components connected to the first crushing roller and the second crushing roller are staggered with each other. When gangue is stuck between two adjacent crushing components on the first crushing roller, the crushing component on the second crushing roller can collide with the gangue to make it fall off. Similarly, when gangue is stuck between two adjacent crushing components on the second crushing roller, the crushing component on the first crushing roller can also knock it down to prevent the crushing component from being stuck and unable to work, thereby reducing the separation effect. The two cooperate with each other, and there is no need to manually remove the stuck gangue.

[0014] (2) In the intelligent gangue sorting system of the present invention, when the arc cover rotates and approaches the conveyor belt, the arc cover will contact the gangue on the surface of the conveyor belt. Three types of gangue will appear on the surface of the conveyor belt. The first type is complete gangue. The complete gangue has a high hardness. After the arc cover contacts it, the crushing head will pierce the complete gangue. However, the complete gangue has a high hardness and will not be crushed by the crushing head. Therefore, the arc cover is subjected to pressure and drives the sliding column to slide into the sliding groove. At the same time, the sliding column compresses the support spring, and the arc cover After the cover is no longer in contact with the complete gangue, the arc cover is no longer under pressure, and the supporting spring stretches to drive the sliding column to slide out of the sliding groove and reset. The second type is coal. The hardness of coal is low. After the arc cover comes into contact with it, the crushing head on the arc cover can directly crush the coal block. The third type is a combination of coal and gangue. After the arc cover comes into contact with it, due to the low hardness of coal, the crushing head can directly crush the coal block, while the gangue will not be crushed due to its high hardness, so that the coal block will fall off the gangue, completing the separation of the coal and gangue combination.

[0015] (3) The intelligent gangue sorting system described in the present invention has an arc cover made of elastic metal. When the arc cover is subjected to pressure, the sliding rod drives the arc cover to slide, and the back of the arc cover is pushed by the top rod. At this time, the arc cover will be deformed and its concave surface will be turned outward. When the concave surface of the arc cover is turned outward, it will drive the crushing head to open outward. At the same time, in the previous process, the crushing head has been piercing the coal gangue, so when the crushing head opens, it will peel off the coal blocks on the coal gangue, which can accelerate the separation of coal gangue and coal blocks and improve the separation quality.

[0016] (4) In the intelligent gangue sorting system described in the present invention, when the gangue passes through the wave surface, the gangue will move or flip itself when passing through the high point and slope of the wave surface, thereby realizing the flipping of the gangue during rolling, which is beneficial to the processing of the gangue by the rolling assembly and the crushing assembly.

DETAILED DESCRIPTION

[0025] The embodiment of the present invention provides an intelligent gangue separation system for gangue, which solves the problem that the traditional jig uses water as a mineral separation medium and uses the difference in specific gravity between the selected mineral and the gangue. The water flows into the jig chamber through the screen plate, so that the bed layer rises and becomes slightly loose. The particles with high density enter the bottom layer due to the large local pressure and sedimentation velocity, and the particles with low density move to the upper layer to achieve separation. The machine can separate the gangue and the coal block without sticking to each other. However, in the display, most of the gangue and the coal block are stuck to each other. Generally, the coal layer is wrapped around the outside of the gangue, so that the technical problem of separation cannot be achieved by the specific gravity of the gangue.

[0026] The technical solution in the embodiment of the present invention is to solve the above technical problems. The overall idea is as follows: the roller pressing component 2 is used to drive the crushing component 3 to squeeze the coal gangue distributed on the conveyor belt 15. During the squeezing, the arc surface cover rotates close to the conveyor belt, and the arc surface cover will contact the coal gangue on the surface of the conveyor belt. Three forms of coal gangue will appear on the surface of the conveyor belt. The first form is complete coal gangue. The complete coal gangue has a high hardness. After the arc surface cover contacts it, the crushing head will pierce the complete coal gangue, but the complete coal gangue has a high hardness and will not be crushed by the crushing head. Therefore, the arc surface cover is pressed to drive the sliding column to slide into the sliding groove, and the sliding column After the support spring is compressed, the arc cover is no longer in contact with the complete gangue, so the arc cover is no longer under pressure, and the support spring stretches to drive the sliding column to slide out of the sliding groove and reset. The second type is coal, which has a low hardness. After the arc cover contacts it, the crushing head on the arc cover can directly crush the coal block. The third type is a combination of coal and gangue. After the arc cover contacts it, due to the low hardness of the coal, the crushing head can directly crush the coal block, while the gangue will not be crushed due to its high hardness, so that the coal block will fall off the gangue, completing the separation of the combination of coal and gangue, and then the jig uses the specific gravity of the gangue to separate the coal block and gangue.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] like Figure 1 , Figure 3 and Figure 6 As shown, the intelligent gangue separation system of the present invention comprises:

[0029] Workbench 12;

[0030] The first crushing roller 21 is rotatably connected to the workbench 12 via a bracket, and a crushing assembly 3 is fixedly connected to the first crushing roller 21;

[0031] The crushing assembly 3 includes a sliding groove 31, a sliding column 32, a supporting spring 33, a curved cover 34 and a crushing head 35. The sliding groove 31 is fixedly connected to the first crushing roller 21, and the sliding column 32 is slidably connected in the sliding groove 31. One end of the sliding column 32 close to the first crushing roller 21 is inside the sliding groove 31, and one end of the sliding column 32 close to the first crushing roller 21 is fixedly connected to one end of the supporting spring 33, and the other end of the supporting spring 33 is fixedly connected to the bottom of the sliding groove 31, that is, the outer wall of the first crushing roller 21. One end of the sliding column 32 away from the first crushing roller 21 extends out of the sliding groove 31 and is fixedly connected to the convex surface of the curved cover 34, and the crushing head 35 is fixedly connected to the concave surface of the curved cover 34. The top rod 36 is fixedly connected to the sliding groove 31, and the top rod 36 cooperates with the curved cover 34, and the curved cover 34 is elastic metal.

[0032] In the embodiment, the first crushing roller 21 and the second crushing roller 22 drive the sliding groove 31 to rotate when rotating, the sliding groove 31 drives the sliding column 32 to rotate, the sliding column 32 drives the arc cover 34 to rotate, and when the arc cover 34 rotates and approaches the conveyor belt 15, the arc cover 34 will contact the coal gangue on the surface of the conveyor belt 15, and three forms of coal gangue will appear on the surface of the conveyor belt 15:

[0033] The first type is complete gangue. Complete gangue has high hardness. After the arc cover 34 contacts it, it will squeeze it toward the conveyor belt 15. The conveyor belt 15 is supported by the workbench 12 below. The crushing head 35 will pierce the complete gangue, but the complete gangue has high hardness and will not be crushed by the crushing head 35. Therefore, the arc cover 34 is pressed to drive the sliding column 32 to slide into the sliding groove 31. At the same time, the sliding column 32 compresses the supporting spring 33. After the arc cover 34 is no longer in contact with the complete gangue, the arc cover 34 is no longer pressed. The supporting spring 33 stretches to drive the sliding column 32 to slide out of the sliding groove 31 and reset.

[0034] The second type is coal, which has low hardness. After the arc cover 34 contacts the coal, the crushing head 35 on the arc cover 34 can directly crush the coal.

[0035] The third type is a combination of coal and coal gangue. After the arc cover 34 comes into contact with it, the crushing head 35 can directly crush the coal block due to the low hardness of the coal, while the coal gangue will not be crushed due to its high hardness, so the coal block will fall off the coal gangue, completing the separation of the combination of coal and coal gangue.

[0036] It should be understood that the arc cover 34 is made of elastic metal. When the arc cover 34 is subjected to pressure and moves toward the sliding groove 31, the back of the arc cover 34 will be pushed by the push rod 36. At this time, the arc cover 34 will be deformed and its concave surface will be turned outward. When the concave surface of the arc cover 34 is turned outward, it will drive the crushing head 35 to open. Because in the previous process, the crushing head 35 has been piercing the coal gangue, the coal blocks on the coal gangue will be peeled off when the crushing head 35 opens, which can speed up the separation of coal gangue and coal blocks and improve the quality of separation.

[0037] Further, such as Figure 1 , Figure 2 and Figure 5 As shown, the transport component 1 is below the crushing component 3, and the transport component 1 includes a slide rail 11. The workbench 12 is provided on one side of the slide rail 11, and the workbench 12 is fixedly connected to the support leg 13. The workbench 12 has rollers 14 at both ends, and the rollers 14 are rotatably connected to the support leg 13. A conveyor belt 15 is nested on the roller 14. Teeth 17 are fixedly connected to both sides of the roller 14, and the teeth 17 are meshed with tooth holes 110. The tooth holes 110 are provided on the connecting strip 19, and the connecting strip 19 is fixedly connected to both sides of the conveyor belt 15. A jig 112 is provided below the end of the conveyor belt 15, and baffles 16 are provided on both sides of the conveyor belt 15. The baffles 16 are fixedly connected to the workbench 12, and one end of the baffle 16 away from the jig 112 is fixedly connected to the slide rail 11. The discharge port of the slide rail 11 is above the conveyor belt 15, and the slide rail 11 does not contact the conveyor belt 15.

[0038] In the embodiment, the gangue falls from the slide rail 11 onto the conveyor belt 15, and the roller 14 is powered by an external motor. When the roller 14 rotates, the teeth 17 are driven to rotate. Because the teeth 17 and the tooth holes 110 are engaged, the rotation of the teeth 17 drives the connecting strip 19 to move. The movement of the connecting strip 19 drives the conveyor belt 15 to rotate in a circle, and the gangue moves slowly toward the jig 112 along the conveyor belt 15.

[0039] Further, such as Figure 1 and Figure 4As shown, the roller assembly 2 is fixedly connected to the workbench 12 by a bracket, and the roller assembly 2 includes the first crushing roller 21, which is fixedly connected to the workbench 12 through a bracket, and a second crushing roller 22 is provided on one side of the first crushing roller 21, and the second crushing roller 22 is also fixedly connected to the workbench 12 by a bracket, and a first gear 23 is fixedly connected to one end of the first crushing roller 21, and the first gear 23 is meshed with a main gear 25, and the main gear 25 is meshed with a second gear 24, and the second gear 24 is fixedly connected to one end of the second crushing roller 22, and the first crushing roller 21 and the second crushing roller 22 are both staggeredly distributed with the crushing assembly 3, and the first crushing roller 21 and the second crushing roller 22 are above the conveyor belt 15, and the gap between them can be used for coal gangue, and the rotating shaft 28 is fixedly connected to the main gear 25, and one end of the belt 26 is nested on the rotating shaft 28, and the other end of the belt 26 is rotatably connected to a turntable 27, and the turntable 27 is fixedly connected to one side of the drum 14.

[0040] In the embodiment, when the drum 14 rotates, it drives the turntable 27 to rotate. The rotation of the turntable 27 drives the belt 26 to rotate. The rotation of the belt 26 drives the rotating shaft 28 to rotate. The rotation of the rotating shaft 28 drives the main gear 25 to rotate. The rotation of the main gear 25 drives the first gear 23 and the second gear 24 to rotate. After the first gear 23 and the second gear 24 rotate, they respectively drive the first crushing roller 21 and the second crushing roller 22 to rotate.

[0041] It should be understood that the number of teeth of the first gear 23 is greater than the number of teeth of the second gear 24, so the rotation speed of the first crushing roller 21 is slower than the rotation speed of the second crushing roller 22, and the crushing components 3 connected to the first crushing roller 21 and the second crushing roller 22 are staggered with each other. When coal gangue is stuck between two adjacent crushing components 3 on the first crushing roller 21, the crushing component 3 on the second crushing roller 22 can collide with the coal gangue to make it fall off. Similarly, when coal gangue is stuck between two adjacent crushing components 3 on the second crushing roller 22, the crushing component 3 on the first crushing roller 21 can also knock it down.

[0042] Further, such as Figure 1 and Figure 2 As shown, the flip assembly 4 is arranged below the conveyor belt 15 , the flip assembly 4 is arranged on the workbench 12 , the flip assembly 4 includes a wavy surface 41 , the wavy surface 41 is arranged on the workbench 12 , and the conveyor belt 15 is in close contact with the wavy surface 41 .

[0043] In the embodiment, there is coal gangue on the conveyor belt 15, so the conveyor belt 15 will transport the coal gangue close to the wave surface 41. When the coal gangue passes through the wave surface 41, the coal gangue will move or flip by itself when passing through the high point and slope of the wave surface 41, thereby realizing the flipping of the coal gangue during rolling, which is beneficial to the processing of the coal gangue by the rolling component 2 and the crushing component 3.

[0044] During operation, the gangue falls from the slide rail 11 onto the conveyor belt 15, and the drum 14 is powered by an external motor. When the drum 14 rotates, the teeth 17 are driven to rotate. Because the teeth 17 and the tooth holes 110 are engaged, the teeth 17 are driven to move the connecting strip 19 when rotating, and the movement of the connecting strip 19 drives the conveyor belt 15 to rotate in a circle. The gangue moves slowly toward the direction of the jigger 112 along with the conveyor belt 15. When the drum 14 rotates, the turntable 27 is driven to rotate, and the rotation of the turntable 27 drives the belt 26 to rotate. The rotation of the belt 26 drives the rotating shaft 28 to rotate, and the rotation of the rotating shaft 28 drives the main gear 25 to rotate. The rotation of the main gear 25 drives the first gear 23 and the second gear 24 to rotate. After the first gear 23 and the second gear 24 rotate, they respectively drive the first crushing roller 2 1 and the second crushing roller 22 rotate, the first crushing roller 21 and the second crushing roller 22 drive the sliding groove 31 to rotate when rotating, the sliding groove 31 rotates and drives the sliding column 32 to rotate, the sliding column 32 rotates and drives the arc cover 34 to rotate, when the arc cover 34 rotates and approaches the conveyor belt 15, the arc cover 34 will contact with the coal gangue on the surface of the conveyor belt 15, and three forms of coal gangue will appear on the surface of the conveyor belt 15. The first form is complete coal gangue, which has a high hardness. After the arc cover 34 contacts it, it will squeeze it toward the conveyor belt 15. The conveyor belt 15 is supported by a workbench 12 below, and the crushing head 35 will pierce the complete coal gangue, but the complete coal gangue has a high hardness and will not be pierced by the crushing head 35, so the arc cover 34 is pressed and drives the sliding column 32 slides into the sliding groove 31, and at the same time, the sliding column 32 compresses the supporting spring 33. After the arc cover 34 is no longer in contact with the complete coal gangue, the arc cover 34 is no longer under pressure, and the supporting spring 33 stretches to drive the sliding column 32 to slide out of the sliding groove 31 to reset. The second type is coal, and the hardness of coal is low. After the arc cover 34 contacts it, the crushing head 35 on the arc cover 34 can directly crush the coal block. The third type is a combination of coal and coal gangue. After the arc cover 34 contacts it, due to the low hardness of coal, the crushing head 35 can directly crush the coal block, and the coal gangue will not be crushed due to its high hardness, so that the coal block will fall off the coal gangue, completing the separation of the coal and coal gangue combination. The arc cover 34 is elastic metal. When the arc cover 34 is under pressure, the arc cover 3 When the cambered cover 34 moves toward the sliding groove 31, the back side of the cambered cover 34 will be pushed by the push rod 36, and the cambered cover 34 will be deformed, and its concave surface will be turned outward. When the concave surface of the cambered cover 34 is turned outward, the crushing head 35 will be driven to open. Because the crushing head 35 has been piercing the coal gangue in the previous process, the coal blocks on the coal gangue will be peeled off when the crushing head 35 is opened, which can speed up the separation of the coal gangue and the coal blocks, and also improve the separation quality. There is coal gangue on the conveyor belt 15, so the conveyor belt 15 will transport the coal gangue close to the wave surface 41. When the coal gangue passes through the wave surface 41, the coal gangue will move or turn over by itself when passing the high point and slope of the wave surface 41, so that the coal gangue can be turned over during rolling, which is beneficial to the processing of the coal gangue by the rolling component 2 and the crushing component 3.Then the gangue and coal lumps enter the jig 112 for separation.

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
