Technical Field
[0001] This utility model relates to the field of impurity removal equipment technology, specifically to an impurity removal device for refractory material raw materials after crushing. Background Technology
[0002] Refractory materials are inorganic non-metallic materials with extremely high melting points. They are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate industry, power industry and other industrial fields.
[0003] Refractory material raw materials mainly include natural and synthetic high-temperature resistant minerals, such as refractory clay, siliceous raw materials, and high-alumina bauxite. However, during the composition, mining, calcination, and storage of these raw materials, some impurities may be present or mixed in, most notably iron-containing impurities and dust. These impurities can affect product quality, therefore, it is necessary to treat the impurities in the refractory material raw materials. Generally, this treatment is carried out after the refractory material raw materials are crushed to avoid difficulties in processing after later grinding.
[0004] The existing method uses magnetic conveyor belts for iron removal. These conveyor belts require specialized manufacturers, resulting in frequent maintenance and relatively high costs. Dust is simply treated by the raw material washing process at the upstream station, rather than targeted treatment, and the effectiveness needs improvement. Therefore, a device for removing impurities after crushing refractory raw materials urgently needs to be developed. Utility Model Content
[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a device for removing impurities after crushing refractory material raw materials. This device integrates dust removal and iron removal. Iron is attracted above the raw materials by a drum with an internal magnet. The rotating drum causes the attracted magnets to be intercepted and removed by a scraper. At the same time, a rotary joint is set at the center of one side of the drum, which connects to an external dust collection system. Dust enters the rotary joint through the dust removal port on the drum and is discharged. The device has a simple structure, is easy to maintain, has low cost, and provides good dust and iron removal effects, making it highly practical.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for removing impurities after crushing refractory material raw materials, comprising a hopper, a support plate, a conveyor belt, a pair of mounting plates, a roller, a dust removal system, and baffles. The conveyor belt is mounted on the support plate and has guard plates on both sides.

Support legs are provided on both sides of the discharge end of the conveyor belt, and a pair of mounting plates are respectively mounted on the support legs. The roller is rotatably mounted between the pair of mounting plates. A rotary joint communicating with the interior is located at the center of one side of the roller, and is rotatably connected to the mounting plates through the rotary joint. The other end of the connector is connected to a dust removal pipe, which is connected to a dust removal system. A rotating shaft is located at the center of the other side of the roller, and the rotating shaft is rotatably connected to the mounting plate. A motor is located on the outside of the mounting plate, and the output end of the motor is connected to the rotating shaft. Multiple axially designed magnets are arranged in a ring matrix on the inner side wall of the roller. Multiple dust removal ports are evenly arranged on the roller at positions staggered from the magnets. A collection box is arranged between the mounting plates, and a scraper is arranged on the side wall of the collection box. The scraper is close to the surface of the roller, and the rotation direction of the roller can scrape off the iron-containing impurities adsorbed on its surface and put them into the collection box. A baffle is arranged between a pair of guard plates, and a certain distance is set between the bottom of the baffle and the upper surface of the conveyor belt.
[0007] Preferably, sliders are provided on both sides of the baffle, and a vertical groove is provided on the inner sidewall of the center position of the guard plate. The sliders are vertically slidably connected to the groove, and screws are screwed onto the outer side of the guard plate corresponding to the groove position.

[0019] like Figure 1-2As shown, a device for removing impurities after crushing refractory material raw materials includes a hopper 14, a support plate 3, a conveyor belt 2, a pair of mounting plates 7, a drum 8, a dust removal system 20, and baffles 13. The conveyor belt 2 is mounted on the support plate 3 and has guard plates 1 on both sides. The hopper 14 is positioned above the feed end of the conveyor belt 2 and is used to transfer and receive the crushed refractory material raw materials. Support legs 4 are provided on both sides of the discharge end of the conveyor belt 2, and a pair of mounting plates 7 are respectively mounted on the support legs 4. The drum 8 is rotatably mounted between the pair of mounting plates 7. A rotary joint 11 communicating with the interior is provided at the center of one side of the drum 8, and is rotatably connected to the mounting plate 7 through the rotary joint 11. The other end of the rotary joint 11 is connected to a dust removal pipe 19, which is connected to the dust removal system 20. A rotating shaft 18 is provided at the center of the other side of the drum 8, and is rotatably connected to the mounting plate 7. A motor 17 is provided on the outside of the mounting plate 7, and the output end of the motor 17 is connected to the rotating shaft 18. The inner wall of the drum 8 is annular. The matrix is equipped with multiple axially designed magnets 9. Multiple dust collection ports 10 are evenly arranged on the roller 8, staggered from the magnets 9. A collection box 5 is positioned between the mounting plates 7. A scraper 6 is installed on the side wall of the collection box 5, close to the surface of the roller 8. The rotation direction of the roller 8 allows iron-containing impurities adsorbed on its surface to be scraped off by the scraper 6 and enter the collection box 5. A baffle 13 is positioned between a pair of guard plates 1, with a certain distance between the bottom of the baffle 13 and the upper surface of the conveyor belt 2. Slider blocks 15 are installed on both sides of the baffle 13. A vertical groove 12 is installed on the inner side wall of the center position of the guard plate 1, and the slider 15 slides vertically with the groove 12. A screw 16 is screwed onto the outer side of the guard plate 1 corresponding to the groove 12, and the screw 16 abuts against the slider 15. The baffle 13 is arc-shaped, with the convex side facing the incoming material side. The support leg 4 is retractable and can be fixed. The roller 8 is made of aluminum alloy with low magnetic permeability. The surface of the conveyor belt 2 is covered with a wear-resistant material.
[0020] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:
[0021] According to the instruction manual Figure 1-2 As can be seen, during operation of this utility model, the externally crushed refractory material raw material is fed into the feed hopper 14 and falls onto the conveyor belt 2. The feed rate of the feed hopper 14 is controllable and can be controlled by a valve. The raw material mainly falls into the central position. Figure 1For example, conveyor belt 2 rotates clockwise, and the raw material falling on conveyor belt 2 is conveyed to the right. Since there is a certain distance between baffle 13 and the upper surface of conveyor belt 2, this distance can be set according to actual needs. The raw material with a higher center is blocked by baffle 13 and distributed to both sides of conveyor belt 2 to ensure that the thickness of the raw material on conveyor belt 2 is uniform, in order to better remove iron and dust. The raw material continues to be conveyed and passes under the roller 8 between a pair of mounting plates 7. The roller 8 and the mounting plate 7 are rotatably connected. The roller 8 is rotated by the motor 17 driving the rotating shaft 18. The roller 8 has multiple axially designed magnets 9 arranged in a ring matrix inside. Through the roller 8, iron-containing impurities can be adsorbed. The iron-containing impurities in the raw material on conveyor belt 2 are adsorbed onto the outer wall of roller 8. Here, roller 8 rotates clockwise, and the iron-containing impurities on the outer wall of roller 8 are scraped off by scraper 6 and fall into collection box 5 for collection. Meanwhile, the external dust removal system 20 operates. This dust removal system 20 includes an induced draft fan and a filtration mechanism, which is existing technology. It treats dust in the raw materials through the dust removal pipe 19, the rotary joint 11, and the dust removal port 10 on the drum 8. It can also suck up lighter impurities in the raw materials, such as branches and leaves, or small iron-containing impurities, which may also enter the dust removal port 10 without affecting the overall dust removal and iron removal effect. Dust and other impurities pass through the dust removal port 10, the inner cavity of the drum 8, the rotary joint 11, and the dust removal pipe 19 to the dust removal system 20. This utility model integrates dust removal and iron removal. The drum 8, which has an internal magnet 9, attracts iron above the raw materials. The rotating drum 8 drives the attracted magnet 9 to be intercepted and removed by the scraper 6. At the same time, a rotary joint 11 is set at the center of one side of the drum 8, which is connected to the external dust collection system. Dust enters the rotary joint 11 through the dust removal port 10 on the drum 8 and is discharged. The structure is simple, easy to maintain, low in cost, and has good dust removal and iron removal effect, making it highly practical.
[0022] The baffle 13 has sliders 15 on both sides, and the inner wall of the guard plate 1 has a vertical groove 12 at its center. The sliders 15 and the groove 12 are vertically slidably connected. Screws 16 are screwed onto the outer side of the guard plate 1 at the position corresponding to the groove 12. The screws 16 abut against the sliders 15. This means the height of the baffle 13 can be adjusted, thereby adjusting the thickness of the raw material on the conveyor belt 2. Furthermore, the support leg 4 is retractable and can be fixed. The height of the mounting plate 7 and the rollers 8 and collection box 5 on the mounting plate 7 can be adjusted. To change the impurity removal effect, all the above adjustments can be made according to actual needs; the adjustments are convenient and quick.
[0023] Among them, the baffle 13 is arc-shaped, with the convex side of the arc facing the incoming material side, which can reverse the material with a higher center to both sides, making it flat and uniform, and improving the subsequent dust removal and iron removal effect.
[0024] Among them, roller 8 is made of aluminum alloy with low magnetic permeability to improve the adsorption effect on iron-containing impurities. The surface of conveyor belt 2 is covered with wear-resistant material to improve its service life.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
