Description

Technical Field

[0001] This utility model relates to the field of ore crushing technology, specifically a ore crusher with screening function. Background Technology

[0002] After ore is mined, ore crushing is an important step in mineral processing. Its main purpose is to break the mined ore into smaller particles through physical methods for subsequent processing. However, during the mining process, iron ore is often mixed with ordinary ore. Existing ore crushers do not have iron removal functions and do not have dust collection functions. During ore crushing, a large amount of dust is generated and floats. When workers collect the ore, they will inhale a large amount of dust, which will cause harm to their health and pose a safety hazard. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a crusher with ore screening function. Through the setting of the iron removal component, during the ore conveying process, iron ore will be magnetically attracted to the conveyor belt by magnets and scraped into the collection box by scrapers. This reduces the impact force generated by the ore falling and avoids damage to the internal structure of the crusher. At the same time, the iron ore in the ore is removed. Through the setting of the dust removal component, the rotation of the screening cylinder causes the ore to fall from the large screen plate and the small screen plate, realizing screening and preventing the ore from accumulating on the top of the large screen plate. The smaller particles are thrown out of the screening cylinder by centrifugal force, reducing the dust particles inside the screening cylinder and preventing workers from inhaling a large amount of dust when handling the screened ore.

Detailed Implementation

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1-7 As shown, a crusher with ore screening function includes: a crusher body 1, with a dust collection box 4 fixedly installed at the bottom inside the crusher body 1; an iron removal assembly disposed inside the crusher body 1, which includes: a conveyor belt 302, a magnet 303, a fixing plate 304, and a scraper 305; and a dust removal assembly disposed inside the dust collection box 4, which includes: a screening cylinder 5, a large screen plate 502, a small screen plate 503, an anti-collision net 504, and a dust removal net 505.

[0026] In this system, the iron removal component ensures that during ore conveying, iron ore is magnetically attracted to the conveyor belt 302 by magnet 303 and scraped into the collection box 306 by scraper 305. This reduces the impact of falling ore, preventing damage to the internal structure of the crusher, and simultaneously removes iron ore from the ore. The dust removal component, through the rotation of the screening cylinder 5, causes the ore to fall from the large screen plate 502 and the small screen plate 503, achieving screening and preventing ore accumulation on top of the large screen plate 502. Centrifugal force also throws smaller particles out of the screening cylinder 5, reducing dust particles inside and preventing workers from inhaling large amounts of dust when handling the screened ore.

[0027] The crusher body 1 has a bracket 101 fixedly installed on its outer side, two feed pipes 102 fixedly installed on its top, multiple motors a2 fixedly installed on its outer side, a rotating shaft 201 driven by one side of each motor a2, a crushing roller 202 fixedly installed on the outer surface of the rotating shaft 201, multiple crushing plates 203 fixedly installed on the inner wall of the crusher body 1, a partition plate 204 fixedly installed inside the crusher body 1, and a guide tube 205 fixedly installed in the middle of the partition plate 204. A guide plate is fixedly connected to the bottom of the 5-crusher body 1. A motor b3 is fixedly installed on the outside of the crusher body 1. A rotating shaft 301 is driven and connected to one side of the motor b3. A conveyor belt 302 is rotatably connected to the outer surface of the rotating shaft 301. Multiple magnets 303 are fixedly installed inside the conveyor belt 302. A fixing plate 304 is fixedly installed on one side of the inner wall of the crusher body 1. A scraper 305 is fixedly installed on the other side of the inner wall of the crusher body 1. The top of the scraper 305 is in contact with the surface of the conveyor belt 302. A collection box 306 is provided inside the crusher body 1.

[0028] When crushing ore, lumps of ore are poured into the crusher body 1 through the feed pipe 102. The motor a2 drives the rotating shaft 201 to rotate, which in turn causes the crushing roller 202 to rotate. Under the squeezing action of the crushing roller 202 and the crushing plate 203, the lumps of ore are crushed into smaller pieces, which fall from the guide pipe 205 into the conveyor belt 302. The guide plate shortens the height from which the ore falls, preventing it from falling directly onto the conveyor belt 302 and thus avoiding damage to the conveyor belt. Belt 302, driven by motor b3, rotates shaft 301, causing conveyor belt 302 to rotate continuously and transport ore. During transportation, magnet 303 will attract iron ore from the ore to the surface of conveyor belt 302. The ore that is not attracted will fall above fixed plate 304 and slide into guide pipe 402 as conveyor belt 302 rotates. When the attracted iron ore comes into contact with scraper 305, it will be scraped off by scraper 305 and fall into collection box 306.

[0029] The dust collection box 4 has a baffle 401 fixedly installed on the top, a through hole on the top, a guide pipe 402 fixedly installed inside the through hole, a motor c403 fixedly installed at the bottom, a connecting block 404 fixedly installed at the bottom, a rotating shaft 405 driven by the top of the motor c403, the rotating shaft 405 rotatably connected to the connecting block 404, a groove on the top of the rotating shaft 405, a screening cylinder 5 inside the dust collection box 4, a protrusion 501 fixedly installed at the bottom of the screening cylinder 5, a large screen plate 502 fixedly installed inside the screening cylinder 5, a small screen plate 503 fixedly installed inside the screening cylinder 5, the small screen plate 503 being located at the bottom of the large screen plate 502, anti-collision nets 504 fixedly installed on both sides of the screening cylinder 5, and a dust removal net 505 fixedly installed on one side of the anti-collision net 504.

[0030] The crushed ore falls from the feed pipe 402 into the screening cylinder 5. The motor C403 drives the rotating shaft 405 to rotate, which in turn drives the screening cylinder 5 to rotate. When the screening cylinder 5 rotates, smaller particles such as dust are thrown out and pass through the anti-collision net 504 and the dust removal net 505 into the space between the dust collection box 4 and the screening cylinder 5. During the rotation of the screening cylinder 5, ores of different sizes also pass through the small screen plate 503 and the large screen plate 502, thereby achieving the screening effect. This ensures that while screening, dust and smaller particles are separated from the required ore. The anti-collision net 504 effectively prevents the rotating ore from damaging the dust removal net 505.

[0031] Working principle:

[0032] When crushing ore, lumps of ore are poured into the crusher body 1 through the feed pipe 102. Motor a2 drives the rotating shaft 201 to rotate, thereby causing the crushing roller 202 to rotate. Under the squeezing action of the crushing roller 202 and the crushing plate 203, the lumps of ore are crushed into small pieces, which fall from the guide pipe 205 into the conveyor belt 302. The guide plate shortens the height from which the ore falls, preventing it from falling directly onto the conveyor belt 302 and damaging it. Motor b3 drives the rotating shaft 301 to rotate, causing the conveyor belt 302 to rotate continuously and transport the ore. During transportation, magnet 303 attracts iron ore from the ore to the surface of the conveyor belt 302. The ore that is not attracted falls above the fixed plate 304 as the conveyor belt 302 rotates and slides into the guide pipe 205. In the feed pipe 402, the adsorbed iron ore is scraped off by the scraper 305 when it comes into contact with it. The scraped iron ore falls into the collection box 306. When the crushed ore falls from the feed pipe 402 into the screening cylinder 5, the motor c403 drives the rotating shaft 405 to rotate. The rotating shaft 405 drives the screening cylinder 5 to rotate. When the screening cylinder 5 rotates, smaller particles such as dust are thrown out and pass through the anti-collision net 504 and the dust removal net 505 into the space between the dust collection box 4 and the screening cylinder 5. During the rotation of the screening cylinder 5, ores of different sizes also pass through the small screen plate 503 and the large screen plate 502, thereby achieving the screening effect. This ensures that while screening, dust and smaller particles are separated from the required ore. The anti-collision net 504 effectively prevents the rotating ore from damaging the dust removal net 505.
