Technical Field
[0001] This utility model relates to the field of coal gangue production and processing technology, specifically to a crushing and screening device for coal gangue production and processing. Background Technology
[0002] Coal gangue is a blackish-gray solid waste generated during coal mining and washing. Its applications include: producing building materials such as cement, bricks, and ceramsite; serving as fuel for power generation (co-firing); being used as a filler material in road construction, a soil remediation agent, and for ecological restoration; and extracting rare metals or preparing high-value-added products (such as zeolite and silicon fertilizer), achieving the dual goals of resource utilization and environmental protection. After mining, coal gangue is crushed and processed for other uses. The crushed coal gangue needs to be screened for subsequent processing.
[0003] Traditional coal gangue crushing and screening devices lack the function of separating metal impurities. If metal fragments mixed in the coal gangue (such as steel bars, nails, etc. mixed in during mining) are not removed, they may damage subsequent processing equipment. Therefore, we propose a crushing and screening device for coal gangue production and processing. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-4 This utility model provides a technical solution: a crushing and screening device for coal gangue production and processing, including a device body 1, a crushing chamber 12 is provided on the top side of the device body 1, a feed inlet 3 is provided on the top side of the crushing chamber 12, a crushing component is installed inside the crushing chamber 12, a fifth discharge port 14 is provided on the bottom side of the crushing chamber 12, a magnetic screening component is installed below the fifth discharge port 14, a filter plate 16, a filter plate 17 and an inclined plate 18 are fixedly installed in the device body 1 from top to bottom, and the fifth discharge port 14 is located above the filter plate 16. A first discharge port 4, a second discharge port 5 and a third discharge port 6 are provided in the front side of the device body 1 from top to bottom, and the top sides of the filter plate 16, the filter plate 17 and the inclined plate 18 are respectively flush with the bottom sides of the first discharge port 4, the second discharge port 5 and the third discharge port 6.
[0017] When this coal gangue crushing and screening device is in operation, the coal gangue to be processed enters the crushing chamber 12 through the feed inlet 3 on the top side of the crushing chamber 12 inside the main body 1. Then, the crushing components installed inside the crushing chamber 12 crush the incoming coal gangue. The crushed coal gangue is discharged through the fifth discharge outlet 14 on the bottom side of the crushing chamber 12. Since the fifth discharge outlet 14 is located above the filter plate 16 and a magnetic screening component is installed below it, the discharged coal gangue first passes through the magnetic screening component. The processed coal gangue falls into the main body 1 and is fixedly installed from top to bottom. Coal gangue that cannot pass through filter plate 16 slides down along filter plate 16 and is discharged from the first discharge port 4 corresponding to the front of the device body 1 from top to bottom. Coal gangue that can pass through filter plate 16 continues to fall onto filter plate 2 17. Coal gangue that cannot pass through filter plate 2 17 slides down along filter plate 2 17 and is discharged from the second discharge port 5 corresponding to the front of the device body 1. Coal gangue that can pass through filter plate 2 17 finally falls onto inclined plate 18 and slides down along inclined plate 18 to the third discharge port 6 corresponding to the front of the device body 1, thus completing the crushing and screening operation of coal gangue.
[0018] The crushing assembly includes a drive motor 2, which is fixedly installed on the right side of the device body 1. Rotating rods 8 are provided on the front and rear sides of the bottom of the crushing chamber 12, and the two sets of rotating rods 8 are rotatably inserted between the left and right sides of the device body 1. Crushing rollers 13 are fixedly sleeved on the two sets of rotating rods 8. The output shaft end of the drive motor 2 is fixedly connected to the right end of one set of rotating rods 8. Gears 9 are fixedly sleeved on the left ends of the two sets of rotating rods 8, and the two sets of gears 9 mesh with each other.
[0019] When the crushing assembly is working, the drive motor 2 is started first. The output shaft of the drive motor 2 is fixedly connected to the right end of one of the two sets of rotating rods 8 on the front and rear sides of the bottom of the crushing chamber 12. Therefore, when the drive motor 2 is running, it will drive the set of rotating rods 8 to rotate around its own axis. Since gears 9 are fixedly sleeved on the left ends of both sets of rotating rods 8 and the two sets of gears 9 mesh with each other, the rotation of one set of rotating rods 8 will drive the other set of rotating rods 8 to rotate synchronously in the opposite direction under the transmission action of the meshing gears 9. Crushing rollers 13 are fixedly sleeved on both sets of rotating rods 8. The rotating rotating rods 8 will synchronously drive the crushing rollers 13 to rotate. Finally, through the coordinated rotation of the two sets of crushing rollers 13, the coal gangue entering the crushing chamber 12 is crushed.
[0020] The magnetic screening assembly includes a magnetic drum 15, which is located between the fifth discharge port 14 and the first filter plate 16. The magnetic drum 15 is located inside the rear side of the device body 1. A fourth discharge port 7 is opened on the rear side of the device body 1. The front end of the fourth discharge port 7 is located below the magnetic drum 15. Rotating shafts 23 are fixedly connected to both the left and right sides of the magnetic drum 15. The two sets of rotating shafts 23 are respectively rotatably inserted through the left and right sides of the device body 1. A second drive motor 10 is fixedly installed on the left side of the device body 1. The output shaft end of the second drive motor 10 is fixedly connected to the left end of one set of rotating shafts 23. A scraping mechanism is provided on the rear side of the magnetic drum 15.
[0021] The scraping mechanism includes a scraper 19, which is hinged to the rear side of the device body 1. The front end of the scraper 19 abuts against the rear side of the magnetic roller 15. Hooks 21 are fixedly connected to the left and right sides of the front part of the scraper 19. Two sets of hooks 20 are fixedly connected to the rear side of the device body 1. A spring 22 is fixedly connected between hooks 20 and hooks 21.
[0022] When the magnetic screening assembly is working, the second drive motor 10 is started first. The output shaft of the second drive motor 10 is fixedly connected to the left end of one of the two sets of rotating shafts 23 on the left and right sides of the magnetic drum 15. The two sets of rotating shafts 23 are respectively rotatably installed on the left and right sides of the device body 1. Therefore, when the second drive motor 10 is running, it will drive the set of rotating shafts 23 to rotate around its own axis, thereby driving the magnetic drum 15, which is fixedly connected to the two sets of rotating shafts 23, to rotate synchronously. When the crushed coal gangue is discharged from the fifth discharge port 14 and passes through the magnetic drum 15, the magnetic drum 15 will adsorb the metal impurities in the coal gangue. Due to the scraper Scraper 19 is hinged to the rear side of the device body 1, and its front end abuts against the rear side of the magnetic drum 15. The hooks 21 on the left and right sides of the front part of scraper 19 are fixedly connected to the two sets of hooks 20 on the rear side of the device body 1 by springs 22. The force of springs 22 can keep scraper 19 in close contact with the surface of magnetic drum 15. As magnetic drum 15 rotates, scraper 19 will scrape off the metal impurities adsorbed on the surface of magnetic drum 15. The scraped metal impurities will fall into the fourth discharge port 7 opened on the rear side of device body 1 and finally be discharged through the fourth discharge port 7, thus completing the separation of metal impurities in coal gangue.
[0023] The diameter of the filter holes in filter plate 16 is larger than that in filter plate 17. Therefore, the crushed coal gangue falls onto filter plates 16, which are fixedly installed from top to bottom inside the main body of the device 1. Since the diameter of the filter holes in filter plate 16 is larger than that in filter plate 17, particles in the coal gangue that cannot pass through the filter holes of filter plate 16 will remain on the surface of filter plate 16 and then slide down along filter plate 16 to the corresponding first discharge port 4 for discharge. Meanwhile, the coal gangue that can pass through the filter holes of filter plate 16 continues to fall onto filter plate 17 for secondary screening. Particles that cannot pass through the filter holes of filter plate 17 remain on the surface of filter plate 17 and slide down along filter plate 17 to the second discharge port 5 for discharge. Particles that can pass through the filter holes of filter plate 17 fall onto inclined plate 18 and are finally discharged from the third discharge port 6.
[0024] Support feet 11 are fixedly connected to the four corners of the bottom of the device body 1. Plastic blocks are fixedly connected to the bottom of the support feet 11. The support feet 11 fixedly connected to the four corners of the bottom of the device body 1 always provide stable support for the device body 1. The plastic blocks fixedly connected to the bottom of the support feet 11 further enhance the contact stability between the support feet 11 and the placement surface.
[0025] Working principle: When this crushing and screening device for coal gangue production and processing is working, the coal gangue to be processed enters the crushing chamber 12 through the feed inlet 3 on the top side of the crushing chamber 12 inside the main body 1. Then, the drive motor 2 is started. The output shaft of the drive motor 2 is fixedly connected to the right end of one of the two sets of rotating rods 8 on the front and rear sides of the bottom of the crushing chamber 12. Therefore, when the drive motor 2 is running, it will drive the set of rotating rods 8 to rotate around its own axis. Since gears 9 are fixedly sleeved on the left ends of both sets of rotating rods 8 and the two sets of gears 9 mesh with each other, the rotation of one set of rotating rods 8 will drive the other set of rotating rods 8 to rotate synchronously in the opposite direction under the transmission action of the meshing gears 9. Crushing rollers 13 are fixedly sleeved on both sets of rotating rods 8. The rotating rotating rods 8 will synchronously drive the crushing rollers 13 to rotate. Finally, through the coordinated rotation of the two sets of crushing rollers 13, the coal gangue entering the crushing chamber 12 is crushed. The crushed coal gangue is discharged through the fifth discharge port 14 opened on the bottom side of the crushing chamber 12. When the crushed coal gangue is discharged from the fifth discharge port 14 and passes through the magnetic drum 15, the drive motor 2 10 is started. The output shaft of the drive motor 2 10 is fixedly connected to the left end of one of the two sets of rotating shafts 23 on the left and right sides of the magnetic drum 15. The two sets of rotating shafts 23 are respectively rotatably installed on the left and right sides of the device body 1. Therefore, when the drive motor 2 10 is running, it will drive the set of rotating shafts 23 to rotate around its own axis, thereby driving the magnetic drum 15, which is fixedly connected to the two sets of rotating shafts 23, to rotate synchronously. During the rotation of the magnetic drum 15, coal gangue will be adsorbed. Metal impurities in the coal gangue are separated by scraper 19, which is hinged to the rear side of the device body 1. Its front end abuts against the rear side of magnetic drum 15. The two hooks 21 on the left and right sides of the front part of scraper 19 are fixedly connected to the two sets of hooks 20 on the rear side of the device body 1 by spring 22. The force of spring 22 can keep scraper 19 in close contact with the surface of magnetic drum 15. As magnetic drum 15 rotates, scraper 19 will scrape off the metal impurities adsorbed on the surface of magnetic drum 15. The scraped metal impurities will fall into the fourth discharge port 7 opened on the rear side of device body 1 and finally be discharged through the fourth discharge port 7, thus completing the separation of metal impurities in coal gangue. The processed coal gangue falls onto the filter plates 16, which are fixedly installed from top to bottom inside the main body of the device 1. Coal gangue that cannot pass through the filter plates 16 slides down to the first discharge port 4, which is opened from top to bottom on the front side of the main body of the device 1, and is discharged. Coal gangue that can pass through the filter plates 16 continues to fall onto the filter plates 17. Coal gangue that cannot pass through the filter plates 17 slides down to the second discharge port 5, which is opened from the front side of the main body of the device 1, and is discharged. Coal gangue that can pass through the filter plates 17 finally falls onto the inclined plate 18 and slides down to the third discharge port 6, which is opened from the front side of the main body of the device 1, and is discharged, thus completing the crushing and screening of coal gangue.
