Description

Technical Field

[0001] This utility model relates to the field of iron removal device technology, and in particular to an iron removal device for slag powder production. Background Technology

[0002] In the production of slag powder, ferromagnetic impurities are often found in the slag raw materials. If these impurities are not effectively removed, they will not only affect the product quality of the slag powder, but may also cause wear and tear on equipment in subsequent processing stages, reduce equipment lifespan, and even cause production failures. However, existing slag powder iron removal devices mostly adopt a single iron-absorbing structure, which has a limited coverage area and insufficient contact between the slag powder and the iron-absorbing components, resulting in low iron impurity adsorption efficiency and easy omissions. At the same time, slag powder is prone to uneven distribution due to adhesion and accumulation during transportation, making it difficult for iron impurities in some areas to contact the iron-absorbing components, further affecting the iron removal effect and failing to meet the requirements of efficient and precise iron removal. Therefore, we have launched a new iron removal device for slag powder production. Utility Model Content

[0003] The main purpose of this utility model is to provide an iron removal device for slag powder production, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An iron removal device for slag powder production includes a support frame with fixed legs at each of the four lower corners. Side plates are located on the left front and left rear sides of the upper part of the support frame. An iron removal assembly is disposed between the two side plates. A conveyor belt is installed inside the support frame. A collection hopper is disposed between the two side plates. A through-hole is located at the center of the front end of the rear side plate. An inclined hopper is located at the rear end of the collection hopper. Scrapers are located on the left and right upper parts of the collection hopper. A collection box is located at the rear end of the support frame. A protective cover is fixedly installed on the front side plate and the front end of the support frame. The front part of the iron removal assembly penetrates the front side plate and extends into the interior of the protective cover.

[0005] Preferably, the iron removal assembly includes a motor, a rotating rod is fixedly installed at the output end of the motor, a driving gear is provided on the front of the outer surface of the rotating rod, a driven gear is meshed with the right side of the outer surface of the driving gear, a rotating rod is fixedly installed through the middle of the front end of the driven gear, and iron-absorbing rollers are fixedly installed on the middle of the outer surfaces of both the rotating rod and the rotating rod, and an auxiliary component is provided on the front of the outer surface of the rotating rod.

[0006] Preferably, the lower inner wall of the collecting hopper and the entire inclined hopper are both inclined with the front higher than the back, the inclined hopper is vertically aligned with the collecting box, and the collecting hopper is located between the two magnetic rollers.

[0007] By adopting the above technical solution, the iron powder in the collection hopper 7 can be automatically slid backward under the action of gravity by utilizing the guiding effect of the inclined structure, and fall smoothly into the corresponding collection box below through the inclined hopper, which can directly receive the material falling off the suction roller.

[0008] Preferably, the upper ends of the two scrapers are tightly fitted to the outer surfaces of the two magnetic rollers, and the rear parts of the outer surfaces of the rotating rod and the rotating rod are rotatably connected to the front end of the rear side plate through bearings.

[0009] By adopting the above technical solution: the scraper is closely attached to the outer surface of the magnetic roller, which can effectively scrape off the iron filings adsorbed by the magnetic roller and maintain its continuous adsorption capacity. The rotating rod and the rotating rod are connected to the side plate through bearings, which not only ensures the stable rotation of the rotating rod and the rotating rod, but also reduces the frictional resistance during rotation.

[0010] Preferably, the lower part of the auxiliary component extends to the left side of the middle of the inner surface of the conveyor belt.

[0011] By adopting the above technical solution, the auxiliary component can directly act on the left side of the middle of the inner surface of the conveyor belt, and apply shaking force to this area of ​​the conveyor belt in a targeted manner.

[0012] Preferably, the auxiliary component includes two drive rods arranged in a left-right correspondence. Each of the two drive rods has four vibrating cams on the rear of its outer surface. The front of the outer surface of both the right drive rod and the rotating rod is provided with a first pulley. The outer surfaces of both first pulleys are movably fitted with a first transmission belt. The rear of the front of the outer surface of both the right and left drive rods are provided with a second pulley. The outer surfaces of both second pulleys are movably fitted with a second transmission belt.

[0013] By adopting the above technical solution: the rotating rod can drive the right driving rod to rotate through the first pulley and the first transmission belt. The right driving rod then drives the left driving rod to rotate synchronously through the second pulley and the second transmission belt, realizing the linkage of the two driving rods. When the shaking cam on the driving rod rotates with the driving rod, it can contact the conveyor belt to realize the shaking function.

[0014] Preferably, the four vibrating cams located on the left and the four on the right are in active contact with the upper part of the inner surface of the conveyor belt, and the front parts of the outer surfaces of the two drive rods are rotatably connected to the inner front wall of the protective cover through bearings.

[0015] By adopting the above technical solution: the vibrating cam contacts the upper part of the inner surface of the conveyor belt. When the driving rod drives the cam to rotate, the convex part of the cam will periodically push up the conveyor belt, causing the conveyor belt to vibrate up and down. The driving rod is connected to the inner front wall of the protective cover through the bearing, which not only ensures the stable rotation of the driving rod, but also protects the driving rod, cam and other components through the protective cover to avoid interference from external impurities.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, after the motor starts, it drives the rotating rod to rotate, which in turn drives the magnetic roller in the middle of the rotating rod to rotate synchronously. At the same time, the driving gear at the front end of the rotating rod drives the driven gear, causing the rotating rod and the magnetic roller in the middle to rotate in opposite directions, forming a relatively rotating iron removal structure. The relatively rotating method allows the two magnetic rollers to cover a wider area, and the contact opportunities between the slag powder and the magnetic roller during the conveying process increase, thereby improving the adsorption efficiency of iron impurities and reducing the situation where iron impurities are not adsorbed and are missed. 2. In this utility model, by setting a first pulley, a second pulley, and a rotating rod, when the rotating rod rotates, the first pulley at its front end drives the right driving rod to rotate synchronously through the first transmission belt. The right driving rod then drives the left driving rod to rotate synchronously through the second pulley and the second transmission belt. The shaking cam at the rear of the two driving rods rotates with the driving rods and makes contact with the upper part of the inner surface of the conveyor belt, causing the conveyor belt to shake. This prevents slag powder from sticking or accumulating on the conveyor belt, ensuring that the material is evenly distributed and smoothly conveyed to the area below the magnetic roller. This avoids the problem of some areas of iron impurities not being adsorbed due to material accumulation. At the same time, the shaking allows more iron impurities in the slag powder to be exposed on the surface, increasing the probability of iron impurities contacting the magnetic roller and further improving the iron removal effect.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-4 This utility model provides a technical solution: A slag powder production iron removal device includes a support frame 1, with fixed legs 2 at each of the four corners of the lower end of the support frame 1. Side plates 3 are provided on the left front and left rear of the upper end of the support frame 1. An iron removal component 4 is provided between the two side plates 3. A conveyor belt 5 is provided inside the support frame 1. A collection hopper 7 is provided between the two side plates 3. A through-hole 6 is provided in the middle of the front end of the rear side plate 3. An inclined hopper 8 is provided at the rear end of the collection hopper 7. Scrapers 9 are provided on the left and right upper ends of the collection hopper 7. A collection box 10 is provided at the rear end of the support frame 1. A protective cover 11 is fixedly installed on the front side plate 3 and the front end of the support frame 1. The front part of the iron removal component 4 penetrates the front side plate 3 and extends into the interior of the protective cover 11.

[0023] In this embodiment, the iron removal assembly 4 includes a motor 41. A rotating rod 42 is fixedly installed at the output end of the motor 41. A drive gear 43 is provided on the front of the outer surface of the rotating rod 42. A driven gear 44 is meshed with the right side of the outer surface of the drive gear 43. A rotating rod 45 is fixedly installed through the middle of the front end of the driven gear 44. A magnetic roller 46 is fixedly installed on the middle of the outer surface of both the rotating rod 45 and the rotating rod 42. An auxiliary assembly 47 is provided on the front of the outer surface of the rotating rod 45. The lower inner wall of the collection hopper 7 and the entire inclined hopper 8 are inclined with the front higher than the back. The inclined hopper 8 corresponds vertically to the collection box 10. The collection hopper 7 is located between the two magnetic rollers 46. The upper ends of the two scrapers 9 are tightly attached to the outer surfaces of the two magnetic rollers 46. The rear parts of the outer surfaces of the rotating rod 45 and the rotating rod 42 are rotatably connected to the front end of the rear side plate 3 through bearings. The lower part of the auxiliary assembly 47 extends to the left side of the middle of the inner surface of the conveyor belt 5.

[0024] Through the above scheme: after the motor 41 starts, its output end drives the rotating rod 42 to rotate, and the magnetic roller 46 in the middle of the rotating rod 42 rotates synchronously; at the same time, the driving gear 43 at the front end of the rotating rod 42 drives the driven gear 44 meshing with it to rotate, and the driven gear 44 drives the rotating rod 45 and the magnetic roller 46 in the middle to rotate in opposite directions, so that the two magnetic rollers 46 form a relative rotating iron removal structure; when the material is conveyed to the area below the magnetic roller 46 by the conveyor belt 5, the magnetic roller 46 adsorbs the ferromagnetic impurities in the material, and rotates with the magnetic roller 46 to the position of the scraper 9, and is scraped off by the scraper 9 into the collection hopper 7 below. Due to the inclined setting of the inner lower wall, which is higher in the front and lower in the back, the ferromagnetic impurities in the collection hopper 7 automatically slide backward to the inclined hopper 8 under the action of gravity, and then fall into the corresponding collection box 10 below through the inclined hopper 8 to complete the collection.

[0025] In this embodiment, the auxiliary component 47 includes two drive rods 471, which are arranged in a left-right correspondence. Each of the two drive rods 471 has four vibrating cams 472 on the rear of its outer surface. The front of the outer surface of the right drive rod 471 and the front of the outer surface of the rotating rod 45 are provided with first pulleys 473. The outer surfaces of the two first pulleys 473 are movably sleeved with first transmission belts 474. The rear of the front of the outer surface of the right drive rod 471 and the rear of the front of the outer surface of the left drive rod 471 are provided with second pulleys 475. The outer surfaces of the two second pulleys 475 are movably sleeved with second transmission belts 476. The four vibrating cams 472 on the left and the four on the right are in movable contact with the upper inner surface of the conveyor belt 5. The front of the outer surface of the two drive rods 471 is rotatably connected to the inner front wall of the protective cover 11 through bearings.

[0026] With the above scheme: when the rotating rod 45 rotates, the first pulley 473 at its front end drives the right driving rod 471 to rotate synchronously through the first transmission belt 474. The right driving rod 471 then drives the left driving rod 471 to rotate synchronously through the second pulley 475 and the second transmission belt 476. The shaking cam 472 at the rear of the two driving rods 471 rotates with the driving rods 471 and makes active contact with the upper part of the inner surface of the conveyor belt 5, causing the conveyor belt 5 to shake, preventing the material from sticking or accumulating on the conveyor belt 5, and ensuring smooth material conveying and iron removal effect.

[0027] It should be noted that this utility model is an iron removal device for slag powder production. During use, after the motor 41 starts, it drives the rotating rod 42 to rotate, which in turn drives the iron-absorbing roller 46 in the middle of the rotating rod 42 to rotate synchronously. At the same time, the driving gear 43 at the front end of the rotating rod 42 drives the driven gear 44, causing the rotating rod 45 and the iron-absorbing roller 46 in the middle to rotate in opposite directions, forming a relatively rotating iron removal structure, thereby improving the iron impurity adsorption efficiency. When the rotating rod 45 rotates, the first pulley 473 at its front end drives the right driving rod 471 to rotate synchronously through the first transmission belt 474. The right driving rod 471 then drives the left driving rod 471 to rotate synchronously through the second pulley 475 and the second transmission belt 476. The rear of the two driving rods 471 The vibrating cam 472 rotates with the drive rod 471 and makes contact with the upper part of the inner surface of the conveyor belt 5, causing the conveyor belt 5 to vibrate. Therefore, when the slag powder is conveyed by the conveyor belt 5 to the area below the magnetic roller 46, the magnetic roller 46 adsorbs the ferromagnetic impurities in the slag powder and rotates with the magnetic roller 46 to the position of the scraper 9, where it is scraped off into the collection hopper 7 below. Due to the inclined setting of the lower inner wall of the collection hopper 7, which is higher in the front and lower in the back, the ferromagnetic impurities in the collection hopper 7 automatically slide backward to the inclined hopper 8 under the action of gravity, and then fall into the corresponding collection box 10 below through the inclined hopper 8 to complete the collection. The vibration of the conveyor belt 5 can prevent the material from sticking or accumulating, ensuring that the material is evenly distributed and smoothly conveyed. At the same time, the vibration can expose the iron impurities in the material to the surface, improving the iron removal effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
