[0039] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0040] like Figures 1-6 As shown, the present invention provides a silicon-aluminum refractory raw material purification device, characterized in that it includes a crushing mechanism 1, a conveying mechanism 2, a conveyor belt mechanism 3 and a magnetic separation mechanism 4 arranged in sequence.

[0041] The crushing mechanism 1 is used for preliminary crushing of silicon-aluminum refractory raw materials. It includes a crushing box 101, inside which two horizontally arranged, rotatably connected crushing rollers 102 are mounted side-by-side. The surfaces of these two crushing rollers 102 can be toothed or textured to enhance the crushing effect. An inclined feed hopper 103 is provided at the top of the crushing box 101 for easy feeding of raw materials. A crushing motor 104 is mounted on the crushing box 101, and the output end of the crushing motor 104 is fixedly connected to the shaft of one of the crushing rollers 102, serving as the driving roller. The ends of the shafts of the two crushing rollers 102 are connected by meshing gears 105, causing the driving roller to drive the driven roller to rotate. The two crushing rollers 102, driven by the meshing gears 105, rotate in opposite directions, compressing and shearing the raw materials.

[0042] The conveying mechanism 2 is used to transport the crushed material to the next process. It includes a conveying channel 201, whose top inlet is connected to the bottom outlet of the crushing box 101, allowing the crushed material to enter smoothly. The conveying channel 201 is a long cylindrical structure arranged horizontally or nearly horizontally, which is beneficial for stable material transport. A conveying auger 202 is installed along the length of the conveying channel 201, with its axis coinciding with the axis of the conveying channel 201. An auger motor 203 is installed on the outside of the conveying channel 201, with its output end connected to the rotating shaft of the conveying auger 202, driving the auger 202 to rotate and thus pushing the material from one end of the channel to the other. Several support columns 204 are installed at the bottom of the conveying channel 201 to support and fix it.

[0043] The conveyor belt mechanism 3 is used to receive and transfer materials conveyed by the conveying mechanism 2. It includes a horizontally arranged conveyor belt 301. The conveyor belt 301 is fixedly positioned directly below the discharge end of the conveying channel 201 by columns 302, ensuring that materials fall accurately onto the conveyor belt 301. The conveyor belt mechanism 3 also includes a transmission motor 303, which is connected to the drive roller of the conveyor belt 301, providing power to the conveyor belt 301. Workers pick up visually identifiable impurities from both sides of the conveyor belt mechanism 3.

[0044] The magnetic separation mechanism 4 is used to remove ferromagnetic impurities that are invisible to the naked eye or too small to be picked up by hand. It includes a horizontally positioned conveyor belt 401. Conveyor belt 401 is fixed above conveyor belt 301 by columns 402. Conveyor belt 401 is located above the discharge end of conveyor belt 301, and its conveying direction is perpendicular to that of conveyor belt 301. This arrangement provides spatial convenience for material separation and collection. An electromagnet 403 is typically installed inside conveyor belt 401, between its drive roller and driven roller, along its length. The electromagnet 403 is elongated, its length covering the effective working area of ​​conveyor belt 401, and generates a strong magnetic field when energized. A collection box 404 is located below conveyor belt 401, between columns 402, to collect the separated ferromagnetic impurities. The opening of the iron collection box 404 faces the working surface (lower surface) of the second conveyor belt 401, ensuring that ferromagnetic impurities attracted by the electromagnet 403 and subsequently detached or scraped off accurately fall into the box. The magnetic separation mechanism 4 also includes a second conveyor motor 405, which is connected to the drive roller of the second conveyor belt 401 to provide power to the second conveyor belt 401. The iron collection box 404 is equipped with a cleaning structure 5 for cleaning the ferromagnetic impurities adsorbed on the lower surface of the second conveyor belt 401 and guiding them into the iron collection box 404.

[0045] The cleaning structure 5 includes: a push rod 501, which is horizontally slidably connected to the iron collection box 404, and its sliding direction is perpendicular to the conveying direction of the second conveyor belt 401, that is, parallel to the width direction of the second conveyor belt 401. A push plate 502 is fixedly installed at the upper end of the push rod 501 near the second conveyor belt 401. A brush 503 or scraper is fixedly installed on the push plate 502 facing the second conveyor belt 401. This brush 503 is used to scrape or brush off ferromagnetic impurities adsorbed on the surface of the second conveyor belt 401. Two guide rods 504 are arranged in parallel, one end of which is fixedly connected to the push plate 502, and the other end passes through the side wall of the iron collection box 404 and is provided with a limit block 505 to restrict the withdrawal of the guide rods 504 and form a sliding guide with the side wall of the iron collection box 404. Two clamping springs 506 are respectively sleeved on the guide rods 504 and located between the push plate 502 and the side wall of the iron collection box 404. These springs allow the push plate 502 and its brush 503 to elastically press against the surface of the conveyor belt 401, ensuring a cleaning effect. A fixed track 507, fixedly mounted on the iron collection box 404, is located on both sides of the push rod 501, providing constraint or locking for the movement of the push rod 501. A slider 508 is fixedly mounted at the end of the push rod 501 away from the push plate 502, i.e., the operating end, for convenient manual operation. Two fixing blocks 509 are located on both sides of the slider 508. Both sides of the slider 508 have a hollow structure, with fixing springs 510 installed inside. The fixing blocks 509 are telescopically mounted on both sides of the slider 508 via the fixing springs 510. Under normal conditions, the fixing blocks 509 extend under the action of the fixing springs 510 and engage with the grooves or positioning holes on the fixed track 507, thereby locking the push rod 501 and brush 503 in a specific position, i.e., a non-working position.

[0046] When the fixed block 509 engages with the fixed track 507, the clamping spring 506 is in a compressed state. When cleaning is required, the operator can pinch or press the sides of the slider 508 to make the fixed block 509 retract against the elastic force of the fixed spring 510, thereby releasing the engagement with the fixed track 507. The brush 503 then closely adheres to the surface of the conveyor belt 401 and scrapes the surface of the conveyor belt 401.

[0047] Working principle:

[0048] The silicon-aluminum refractory raw material is added into the crushing box 101 through the feed hopper 103. The crushing motor 104 is started, and the two crushing rollers 102 are driven to rotate in opposite directions through the gear 105, which crushes the raw material into smaller particles.

[0049] The crushed material falls from the bottom outlet of the crushing box 101 into the conveying channel 201. The auger motor 203 drives the conveying auger 202 to rotate, conveying the material horizontally or nearly horizontally to the other end of the conveying channel 201.

[0050] Material falls from the discharge port of conveyor channel 201 onto the conveyor belt 301 running below. Conveyor motor 303 drives conveyor belt 301 to smoothly transport the material to its end. Workers can pick up visually identifiable impurities from both sides of the conveyor belt mechanism 3.

[0051] When the material is conveyed on conveyor belt 301, electromagnet 403 is energized to generate a magnetic field. Ferromagnetic impurities in the raw material are adsorbed onto the lower surface of conveyor belt 401, while non-magnetic silicon-aluminum materials continue to be conveyed along conveyor belt 301 due to gravity. Ferromagnetic impurities that are adsorbed by electromagnet 403 and subsequently fall off or are scraped off can accurately fall into the box.

[0052] Ferromagnetic impurities adsorbed on the lower surface of conveyor belt 401 move with the belt. When active cleaning is required, the operator can unlock the fixing block 509 at slider 508. The brush 503 of cleaning structure 5, under the action of the clamping spring 506, remains in contact with the surface of conveyor belt 401, either continuously or during operation. The brush 503 scrapes the surface of conveyor belt 401, scraping the adsorbed ferromagnetic impurities into the iron collection box 404 below. The iron collection box 404 can be cleaned periodically.

[0053] In summary, this invention, through the organic combination of a crushing mechanism, a conveying mechanism, a conveyor belt mechanism, and a magnetic separation mechanism, and especially through the magnetic separation design with a cleaning structure, can effectively crush, convey, and magnetically purify silicon-aluminum refractory raw materials, removing ferromagnetic impurities and improving the purity of the raw materials. The device has a relatively simple structure, is easy to operate and maintain, and has good practical value.
