[0002] Coal gangue is a solid waste generated during coal mining and washing processes. It belongs to the low-carbon black-gray rock associated with coal seams and is harder than coal in texture.

Detailed implementation manners

[0033] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings of the specification.

[0034] As Figures 1 to 13As shown, a coal gangue solid waste processing equipment includes: legs 1, a base 2, a screening mechanism 3, a crushing mechanism 4, a driving mechanism 5, an end cover 6, a feed hopper 7, a first discharge port 8, and a second discharge port 9; the legs 1 are installed with the base 2, the base 2 is installed with the screening mechanism 3, and the screening mechanism 3 is used for magnetic separation of coal gangue powder grinding; inside the screening mechanism 3 is provided with the crushing mechanism 4, and the crushing mechanism 4 is used for crushing and grinding coal gangue; the base 2 is installed with the driving mechanism 5, the driving mechanism 5 is located at the rear of the crushing mechanism 4 and the screening mechanism 3, and the driving mechanism 5 is used to drive the crushing mechanism 4 and the screening mechanism 3 to crush, grind and screen coal gangue; the screening mechanism 3 is provided with the end cover 6, the end cover 6 is provided with the feed hopper 7, the screening mechanism 3 is provided with the first discharge port 8, and the first discharge port 8 is used to discharge the crushed stone powder containing iron minerals; the base 2 is provided with the second discharge port 9, and the second discharge port 9 is used to discharge the crushed stone powder without iron minerals.

[0035] Legs 1: Welded with high-strength steel, supporting the entire equipment, ensuring operation stability, and equipped with shock pads to reduce vibration noise. Base 2: Installed on the legs 1, carrying the screening mechanism 3, the crushing mechanism 4, and the driving mechanism 5. Screening mechanism 3: Set above the base 2, mainly used for magnetic separation of the crushed and ground coal gangue powder, internally integrated with an electromagnetic rotating cylinder 32 and a fixed leakage cylinder 31 to achieve efficient separation of iron minerals and non-magnetic components. Crushing mechanism 4: Located inside the screening mechanism 3, using a multi-stage crushing design, including impact crushing by a counterweight hammer 414, shear crushing by an auxiliary rotating cylinder 42, and fine grinding by a grinding roller 43 to ensure that the coal gangue reaches the required particle size. Driving mechanism 5: Installed at the rear of the base 2, driving the crushing mechanism 4 and the screening mechanism 3 to rotate synchronously through a motor, a gear set, and a transmission shaft to ensure the coordinated operation of each component. End cover 6: Sealing the crushing mechanism 4 to prevent dust and crushed slag from spilling out, and equipped with a feed hopper 7 to facilitate continuous feeding of coal gangue. First discharge port 8: Set on the side of the screening mechanism 3, used to discharge the crushed stone powder containing iron minerals for subsequent recovery and utilization of magnetite. Second discharge port 9: Located below the base 2, used to collect the crushed stone powder without iron minerals, which can be reused as building materials or subgrade materials.

[0036] Through the coordinated work of each component, the automatic processing of coal gangue is realized. After the driving motor 51 is started, it drives the rotating shaft 52 to rotate, and at the same time drives the crushing mechanism 4 and the screening mechanism 3 to operate. A high-speed rotating crushing structure is formed by the crushing shaft 412, the crushing rod 413, and the counterweight 414. The rotating shaft 52 makes the auxiliary rotating cylinder 42 rotate in the opposite direction through the third rotating tooth 55 and the fourth rotating tooth 56. The auxiliary rotating cylinder 42 rotates in the opposite direction to the counterweight 414, enhancing the crushing shear force. The crushing nails 422 on the inner wall of the auxiliary rotating cylinder 42 move in the opposite direction to the counterweight 414, forming efficient collision and shear. The crushed material enters the gap between the grinding roller 43 and the fixed leakage cylinder 31 through the through hole 421 of the auxiliary rotating cylinder 42. The auxiliary rotating cylinder 42 drives the grinding roller 43 to roll along the inner wall of the fixed leakage cylinder 31 and cooperate with the arc-shaped protrusion 313 to complete the grinding of the material. The rotating shaft 52 makes the electromagnetic rotating cylinder 32 rotate through the first rotating tooth 53 and the second rotating tooth 54. The electromagnetic rotating cylinder 32 and the auxiliary rotating cylinder 42 rotate independently. The ground powder falls into the inner wall of the electromagnetic rotating cylinder 32 through the leakage holes 311 of the fixed leakage cylinder 31. The iron-containing powder is adsorbed by the electromagnetic rotating cylinder 32 and rotates with it. Non-magnetic powder: directly falls into the aggregate cavity 21 through the sieve holes 321 and is discharged through the second discharge port 9. The adsorbed iron-containing powder rotates with the electromagnetic rotating cylinder 32 to the inclined block 312 of the fixed leakage cylinder 31 and is scraped off and collected through the first discharge port 8.

[0037] As Figures 2 to 9 shown, the screening mechanism 3 includes a fixed leakage cylinder 31 and an electromagnetic rotating cylinder 32. The electromagnetic rotating cylinder 32 is rotatably installed on the fixed leakage cylinder 31. A plurality of leakage holes 311 are annularly arranged on the outer surface of the fixed leakage cylinder 31 centered on the axis. A plurality of arc-shaped protrusions 313 are arranged on the inner wall of the fixed leakage cylinder 31. A plurality of connecting columns 314 are horizontally penetrated on one side of the fixed leakage cylinder 31 close to the driving mechanism 5. One end of the plurality of connecting columns 314 away from the fixed leakage cylinder 31 is connected to the base 2. A plurality of sieve holes 321 are annularly arranged on the outer surface of the electromagnetic rotating cylinder 32 centered on the axis. A plurality of first teeth 322 are annularly arranged on one side of the electromagnetic rotating cylinder 32 close to the connecting column 314 centered on the axis.

[0038] The fixed leakage cylinder 31 serves as the static support component of the screening mechanism 3 and is cast from high-strength wear-resistant alloy steel. A plurality of leakage holes 311 are arranged in a circumferential array along the axial direction on the outer surface of the fixed leakage cylinder 31. The aperture of the leakage holes can be designed according to the requirements of coal gangue treatment to ensure that the ground powder uniformly falls into the electromagnetic rotating cylinder 32. The leakage holes 311 are designed with a tapered flared opening, being narrow at the top and wide at the bottom, to prevent material blockage and improve the passing rate. A plurality of arc-shaped protrusions 313 are provided on the inner wall of the fixed leakage cylinder 31, and a tungsten carbide wear-resistant layer is inlaid on the surface of the protrusions. The arc-shaped protrusions 313 cooperate with the grinding rollers 43 of the auxiliary rotating cylinder 42 to enhance the grinding effect on coal gangue. The wavy arrangement of the arc-shaped protrusions 313 prolongs the residence time of the material and improves the grinding uniformity. A plurality of connecting columns 314 are horizontally penetrated through one side of the fixed leakage cylinder 31 close to the driving mechanism 5 and are fixed to the base 2 by bolts to ensure the overall stability. A plurality of screening holes 321 are arranged in a circumferential array on the outer surface of the electromagnetic rotating cylinder 32. The aperture of the screening holes 321 is slightly larger than that of the leakage holes 311 of the fixed leakage cylinder 31, and the non-magnetic powder directly falls into the aggregate chamber through the screening holes 321. The electromagnetic rotating cylinder 32 and the fixed leakage cylinder 31 can be connected by a rotating shaft 52 bearing to reduce the friction between the two cylinders and reduce the wear degree.

[0039] As Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 10 、 Figure 11 、 Figure 12 and Figure 13 As shown in FIGS.

[0040] The crushing mechanism 4 consists of three major parts: a crushing component 41, an auxiliary rotating cylinder 42, and a grinding roller 43, which realizes the full-process treatment of coal gangue from coarse crushing to fine grinding, and has the characteristics of high crushing efficiency, low energy consumption, and convenient maintenance. As the core of primary crushing, the crushing component 41 is made of high-strength alloy steel. The detachable counterweight hammer 414 adopts a modular design for easy replacement. The counterweight hammer 414 is made of tungsten steel alloy, and its wear resistance is increased by more than 3 times. After the coal gangue enters the auxiliary rotating cylinder 42, it is impacted and crushed by the high-speed rotating counterweight hammer 414. The material is thrown towards the cylinder wall under the action of centrifugal force and collides with the crushing nails 422. The reversely rotating cylinder body and the counterweight hammer 414 form a shearing effect. The crushed material enters between the grinding rollers 43 through the through holes 421, and the grinding rollers 43 and the arc-shaped protrusions 313 form a rolling effect to grind the coal gangue solid waste slag into powder.

[0041] As Figure 13 shown, the crushing component 41 includes a disc 411, a crushing shaft 412, a crushing rod 413, and a counterweight hammer 414. The disc 411 is installed on the connecting column 314. The crushing shaft 412 is rotatably installed on the disc 411. A plurality of crushing rods 413 are arranged in a circumferential array centered on the axis on the crushing shaft 412, and a counterweight hammer 414 is movably installed on adjacent crushing rods 413.

[0042] When crushing the coal gangue solid waste, the rotation of the crushing shaft 412 drives the crushing rod 413 to rotate and drives the counterweight hammer 414 to rotate. The counterweight hammer 414 can rotate on the crushing rod 413, and the weight of the counterweight hammer 414 can be changed according to actual needs, so as to generate a greater impact force when crushing the coal gangue solid waste and improve the crushing efficiency of the coal gangue solid waste.

[0043] As Figures 10 to 12 shown, a plurality of through holes 421 are arranged in a circumferential array centered on the axis on the auxiliary rotating cylinder 42, and the plurality of through holes 421 are respectively located between adjacent grinding rollers 43. A plurality of crushing nails 422 are arranged in a circumferential array centered on the axis on the inner wall of the auxiliary rotating cylinder 42, and the plurality of crushing nails 422 and the plurality of through holes 421 are alternately spaced. A plurality of second teeth 423 are arranged in a circumferential array centered on the axis on one side of the auxiliary rotating cylinder 42 close to the connecting column 314.

[0044] It should be noted that the auxiliary rotating cylinder 42 can be connected to the disc 411 through bearings to reduce friction. The through hole 421 on the auxiliary rotating cylinder 42 is located between adjacent grinding rollers 43, so that the crushed coal gangue solid waste slag can directly fall into the space between the two grinding rollers 43 through the through hole 421. By the rotation of the auxiliary rotating cylinder 42, the grinding rollers 43 are driven to rotate, thereby grinding the coal gangue solid waste slag. The crushing nails 422 on the auxiliary rotating cylinder 42 are provided to make the crushing nails 422 on the inner wall of the auxiliary rotating cylinder 42 move in the opposite direction to the counterweight 414, forming efficient collision and shear, so as to improve the efficiency of coal gangue solid waste crushing. The second teeth 423 provided on the auxiliary rotating cylinder 42 are used to transmit the power on the driving mechanism 5 to the auxiliary rotating cylinder 42 and assist in crushing the coal gangue solid waste.

[0045] As Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 10 and Figure 12 shown, the driving mechanism 5 includes a driving motor 51, a rotating shaft 52, a first rotating tooth 53, a second rotating tooth 54, a third rotating tooth 55 and a fourth rotating tooth 56. The driving motor 51 is horizontally installed inside the base 2. A rotating shaft 52 is installed on the driving motor 51. The rotating shaft 52 passes through the fixed leakage cylinder 31 and the disc 411 respectively, and the rotating shaft 52 is connected to the crushing shaft 412. A first rotating tooth 53 is provided on the rotating shaft 52. The second rotating tooth 54 is provided on the fixed leakage cylinder 31, and the first rotating tooth 53 meshes with the second rotating tooth 54. The second rotating tooth 54 meshes with the first tooth 322. A third rotating tooth 55 is provided on the rotating shaft 52, and the third rotating tooth 55 is located between the fixed leakage cylinder 31 and the disc 411. The fourth rotating tooth 56 is provided on the disc 411, and the third rotating tooth 55 meshes with the fourth rotating tooth 56. The fourth rotating tooth 56 meshes with the second tooth 423.

[0046] The driving mechanism 5 is the power center of the whole set of coal gangue treatment equipment. It adopts a multi-stage gear cooperative transmission design and realizes the linkage control of the crushing mechanism 4 and the screening mechanism 3 through a precise mechanical structure. It is mainly composed of a driving motor 51, a rotating shaft 52, a first rotating tooth 53, a second rotating tooth 54, a third rotating tooth 55 and a fourth rotating tooth 56, and has the characteristics of high transmission efficiency, stable operation and high synchronous accuracy.

[0047] Power is transmitted to the electromagnetic rotating cylinder 32 through the first rotating gear 53 and the second rotating gear 54, so that the electromagnetic rotating cylinder 32 rotates. During the power transmission process, the rotating shaft 52 can be decelerated, greatly reducing the rotation speed of the electromagnetic rotating cylinder 32 and improving the magnetic separation efficiency of the coal gangue solid waste powder. The third rotating gear 55 and the fourth rotating gear 56 transmit power to the auxiliary rotating cylinder 42, making the auxiliary rotating cylinder 42 rotate. The speed of the auxiliary rotating cylinder 42 is slightly lower than that of the rotating shaft 52. Thus, the coal gangue solid waste is crushed and ground by the auxiliary rotating cylinder 42, greatly improving the coordination of the entire system. There is no need for an additional power source to grind and screen the coal gangue solid waste, improving the processing efficiency of the coal gangue solid waste.

[0048] As Figure 8 shown, an inclined block 312 is provided on the outer surface of the fixed leakage cylinder 31, and the lowest end of the inclined block 312 is connected to the first discharge port 8. The width value of the inclined block 312 is equal to the distance value between the inner wall of the electromagnetic rotating cylinder 32 and the outer wall of the fixed leakage cylinder 31.

[0049] After the screening mechanism 3 completes the magnetic separation of the coal gangue solid waste powder, as the electromagnetic rotating cylinder 32 rotates, the inclined block 312 on the fixed leakage cylinder 31 will scrape on the electromagnetic rotating cylinder 32 and scrape off the powder of the iron-containing minerals on the inner wall of the electromagnetic rotating cylinder 32. The scraped-off powder will slide along with the inclined block 312 and be discharged through the first discharge port 8. The connection between the lowest end of the inclined block 312 and the first discharge port 8 is to ensure the smooth discharge of the powder of the iron-containing minerals. The width value of the inclined block 312 is equal to the distance value between the inner wall of the electromagnetic rotating cylinder 32 and the outer wall of the fixed leakage cylinder 31, which is to ensure that all the powder of the iron-containing minerals on the inner wall of the electromagnetic rotating cylinder 32 can be scraped off during the rotation of the electromagnetic rotating cylinder 32 and discharged through the first discharge port 8. It should be noted that the inclined block 312 is made of a non-magnetic material, and the side in contact with the inner wall of the electromagnetic rotating cylinder 32 has a certain flexibility, thereby reducing the wear between the inclined block 312 and the electromagnetic rotating cylinder 32 and greatly improving the magnetic separation efficiency.

[0050] As Figure 2 shown, an aggregate cavity 21 is formed inside the base 2. The aggregate cavity 21 is located below the electromagnetic rotating cylinder 32 and is communicated with the second discharge port 9.

[0051] After the coal gangue solid waste powder is screened by the screening mechanism 3, the powder without iron-containing minerals will fall through the sieve holes 321 on the electromagnetic rotating cylinder 32 into the inside of the aggregate cavity 21 on the base 2. As the coal gangue solid waste powder accumulates, the coal gangue solid waste can be discharged through the second discharge port 9 and used in subsequent construction and other fields. It should be noted that the entire aggregate cavity 21 can be opened from the front end of the device. After opening, tools can be used to transport the accumulated coal gangue solid waste powder inside, thereby improving the working efficiency of the device.

[0052] The diameter value of the through hole 421 is greater than the diameter value of the leakage hole 311.

[0053] Since the through hole 421 is on the auxiliary rotating cylinder 42, and the coal gangue solid waste needs to be crushed by the simultaneous rotation of the crushing component 41 and the auxiliary rotating cylinder 42. After the crushed coal gangue solid waste reaches a certain size, it can directly enter the space between the auxiliary rotating cylinder 42 and the fixed leakage cylinder 31 through the through hole 421, and the coal gangue solid waste residue is further ground by the grinding roller 43 to be ground into powder. After grinding is completed, it can directly enter the screening mechanism 3 through the leakage hole 311. The diameters of the through hole 421 and the leakage hole 311 can be designed according to actual requirements, ensuring that the crushed residue and powder can pass through smoothly without blockage, thereby greatly improving the crushing and grinding efficiency.

[0054] The diameter value of the first rotating tooth 53 is 1 / 2 of the diameter value of the second rotating tooth 54, and the diameter value of the third rotating tooth 55 is equal to the diameter value of the fourth rotating tooth 56.

[0055] It should be noted that when crushing the coal gangue solid waste, since the crushing mechanism 4 and the screening mechanism 3 use the same power source, and the crushing mechanism 4 needs to rotate at a high speed while the screening mechanism 3 does not need to rotate at a high speed. Therefore, the diameter value of the first rotating tooth 53 is 1 / 2 of the diameter value of the second rotating tooth 54, greatly reducing the rotation speed of the second rotating tooth 54. At the same time, since the electromagnetic rotating cylinder 32 is located in the outermost layer and the number of teeth of the first tooth 322 is large, the rotation speed of the electromagnetic rotating cylinder 32 is further reduced, thereby performing magnetic separation on the coal gangue solid waste powder.

[0056] Similarly, the auxiliary rotating cylinder 42 also needs to assist in crushing the coal gangue solid waste, but its rotation speed cannot be too low. Therefore, the diameter value of the third rotating tooth 55 is equal to the diameter value of the fourth rotating tooth 56, which can ensure that the rotation speed of the auxiliary rotating cylinder 42 is not too low and can further assist in crushing the coal gangue solid waste, increasing the crushing efficiency of the coal gangue solid waste.

[0057] Working process of the present invention: First, start the drive motor 51 on the starting drive mechanism 5. After the drive motor 51 starts, it will drive the rotating shaft 52 to rotate. The rotating shaft 52 will drive the crushing shaft 412 on the crushing mechanism 4 to rotate. The crushing shaft 412 will drive the crushing rod 413 to rotate, and the crushing rod 413 will drive the counterweight 414 to rotate. At the same time, the rotating shaft 52 will also drive the third rotating tooth 55 to rotate. Since the third rotating shaft meshes with the fourth rotating tooth 56, it will drive the fourth rotating tooth 56 to rotate. And since the fourth rotating tooth 56 meshes with the second tooth 423, it will drive the entire auxiliary rotating cylinder 42 to rotate on the disk 411. The rotating direction of the counterweight 414 is opposite to that of the auxiliary rotating cylinder 42. During the rotation of the auxiliary rotating cylinder 42, the grinding roller 43 on the outer surface of the auxiliary rotating cylinder 42 will rotate on the inner wall of the fixed leakage cylinder 31.

[0058] At the same time, the rotating shaft 52 will also drive the first rotating tooth 53 to rotate. Since the first rotating tooth 53 and the second rotating tooth 54 mesh with each other, the first rotating tooth 53 will drive the second rotating tooth 54 to rotate. And since the second rotating tooth 54 meshes with the first tooth 322, the second rotating tooth 54 will drive the entire electromagnetic rotating cylinder 32 to rotate on the fixed leakage cylinder 31.

[0059] After the entire device starts, feed the coal gangue solid waste from the feed hopper 7. The coal gangue solid waste will enter the interior of the auxiliary rotating cylinder 42 along the feed hopper 7, and the rotating counterweight 414 will crush the coal gangue solid waste. The auxiliary rotating cylinder 42 will rotate in the reverse direction, and the crushing nails 422 on the inner wall of the auxiliary rotating cylinder 42 will cooperate with the counterweight 414 to further crush the coal gangue solid waste.

[0060] When the coal gangue solid waste is crushed to a certain size, it will enter between the grinding roller 43 and the fixed leakage cylinder 31 through the through holes 421 on the auxiliary rotating cylinder 42. Through the rotation of the auxiliary rotating cylinder 42, the grinding roller 43 rotates on the inner wall of the fixed leakage cylinder 31 and cooperates with the arc-shaped protrusions 313 to grind the coal gangue solid waste slag.

[0061] After the grinding of the coal gangue solid waste slag is completed, it will enter onto the electromagnetic rotating cylinder 32 through the leakage holes 311 on the fixed leakage cylinder 31. The electromagnetic rotating cylinder 32 will be electrified and generate magnetic force. The coal gangue solid waste powder falling from the fixed leakage cylinder 31 will land on the inner wall of the electromagnetic rotating cylinder 32. Through the rotation of the electromagnetic rotating cylinder 32 itself, the powder containing iron minerals will be adsorbed on the inner wall of the electromagnetic rotating cylinder 32, and the powder without iron minerals will fall into the aggregate cavity 21 through the sieve holes 321 with the rotation of the electromagnetic rotating cylinder 32 and be collected, and finally discharged through the second discharge port 9.

[0062] The powder containing iron minerals adsorbed on the inner part of the electromagnetic rotary drum 32 will rotate with the electromagnetic rotary drum 32 and come into contact with the inclined block 312 on the fixed leakage drum 31. The powder on the inner wall of the electromagnetic rotary drum 32 is scraped by the inclined block 312, and the scraped powder will be discharged from the first discharge port 8 through the inclined block 312.

[0063] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
