Abstract
Description
Technical Field
[0001] This invention relates to the field of building material production technology, specifically to a cement preparation device based on industrial waste residue treatment. Background Technology
[0002] With the rapid development of the construction industry and the increasing awareness of environmental protection, utilizing industrial waste (such as electric furnace slag, steel slag, and fly ash) to replace some natural mineral resources in the production of cement clinker has become an important way for the building materials industry to achieve resource recycling and energy conservation and emission reduction. In the cement production process, pretreatment of industrial waste such as crushing, screening, iron removal, and drying is a key step in ensuring cement quality. Therefore, developing efficient and stable waste treatment equipment is of great significance for improving the overall efficiency of cement production lines.
[0003] In existing technologies, the pretreatment of industrial waste typically employs a process layout combining belt conveyors with crushers and iron removal equipment. The working principle is generally as follows: the raw waste is fed via a conveyor belt into a jaw crusher or hammer crusher for initial crushing, and the crushed material is then transported to the next process via the same conveyor belt. Since industrial waste (especially smelting waste) often contains ferromagnetic impurities such as iron nails, iron blocks, or iron filings, to prevent these impurities from damaging subsequent grinding equipment and to ensure the stability of cement composition, existing technologies typically suspend a flat-plate permanent magnet separator or electromagnetic separator above the conveyor belt. When the material passes under the separator with the belt, the strong magnetic field generated by the magnet attracts the iron in the waste, thus achieving slag-iron separation.
[0004] However, the existing iron removal technologies mentioned above have significant limitations in practical applications. Traditional suspended iron removal devices mostly employ static adsorption, where magnets are fixed in place and rely on magnetic force to attract iron. As production continues, the iron impurities adsorbed on the magnet surface accumulate rapidly. These accumulated layers not only occupy effective adsorption space but also create a magnetic shielding effect, causing a significant decrease in the magnet's adsorption force on subsequent materials, easily leading to magnetic saturation. Once the magnet surface is saturated, it cannot effectively remove iron, and the adsorbed iron may even fall back onto the conveyor belt. To clean these accumulated iron deposits, operators often need to pause the conveyor line for manual scraping or intermittent cleaning using complex unloading mechanisms. This not only interrupts production, preventing continuous and automated iron removal and greatly reducing production efficiency, but also often results in low iron removal efficiency due to untimely or incomplete manual cleaning. Residual iron entering subsequent processes can easily damage equipment and seriously affect the purity of cement raw materials. Summary of the Invention

[0016] This invention provides a cement preparation device based on industrial waste residue treatment. It has the following beneficial effects: 1. This invention uses a first motor to drive a rotating column, causing the magnet and rotating rod to rotate synchronously, carrying the adsorbed iron away from the conveying surface. At the same time, a chain and gear transmission drives a cleaning roller to move synchronously with the magnet. A cleaning brush head scrapes away the iron on the surface of the magnet in real time. The equipment continuously adsorbs iron impurities during rotation and completes self-cleaning, achieving uninterrupted continuous operation. This significantly improves the iron removal efficiency and raw material purity, solving the problem of traditional static magnets easily becoming saturated and requiring shutdown for cleaning, thus significantly improving iron removal efficiency and raw material purity.
[0017] 2. This invention uses a hydraulic rod to push the lower pressure plate to compact the material. Combined with the compression buffer of the first spring inside the telescopic cylinder and the guiding effect of the limiting column, it solves the problem of blockage at the crushing feed inlet. It also absorbs the reaction force during crushing through elastic buffering, preventing hard waste residue from damaging the crushing roller and pressure plate, thus ensuring the stability of the crushing process and the life of the equipment.

Smaller waste particles pass directly through the screen openings and fall into the second conveyor belt, while larger waste particles slide down to the first conveyor belt and enter the crushing assembly. This process achieves pre-classification of raw materials, avoids repeated crushing of small particles that already meet the particle size requirements, effectively improves crushing efficiency, and reduces equipment energy consumption.

Detailed Implementation
[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Example: Please see the appendix Figure 1 - Appendix Figure 10This invention provides a cement preparation device based on industrial waste residue treatment, including a processing table 1. The processing table 1 serves as the load-bearing base of the entire device and has a rectangular structure design with sufficient strength and stability. The upper surface of the processing table 1 is bolted with a stepped screening component for raw material grading. A crushing component for grinding large particles is provided on one side of the inner wall of the processing table 1. A first conveyor belt 23 is arranged horizontally on the upper side of the inner wall of the processing table 1 to receive the screened coarse material. A second conveyor belt 24 is arranged parallel to the lower side of the inner wall of the processing table 1 to collect all the processed materials and convey them backward. An iron removal component is arranged across one side above the second conveyor belt 24. The iron removal assembly includes a magnet 29, which is rotatably positioned above the second conveyor belt 24 and within the vertical projection range of the material conveying path. A portal frame 5 is fixedly connected to one side of the upper surface of the second conveyor belt 24. A first motor 25 is mounted on the outer wall of the support frame 5, and a rotating column 27 is fixedly connected to the output end of the first motor 25. A rotating rod 28 is fixedly connected to the outer wall of the rotating column 27. Multiple rotating rods 28 are arranged in a circular array around the axis of the rotating column 27 to expand the adsorption range. A first cleaning roller 37 is rotatably connected to the upper side of the inner wall of the support frame 5, and a second cleaning roller 39 is rotatably connected to the lower side of the inner wall of the support frame 5. The first and second cleaning rollers 37 are parallel to each other, and their outer walls are densely covered with several cleaning brush heads 38. A second sprocket 33 is fixedly connected to one end of the rotating column 27, and a first sprocket 32 is fixedly connected to one end of the first cleaning roller 37. A chain 34 is connected between the first sprocket 33 and the first sprocket 32 to form a synchronous transmission structure. A third gear 35 is fixedly connected to the outermost end of one end of the first cleaning roller 37, and a fourth gear 36 is fixedly connected to one end of the second cleaning roller 39. The teeth of the third gear 35 and the teeth of the fourth gear 36 mesh to achieve the opposite rotation of the two cleaning rollers. A support column 40 is fixedly connected to the middle side of the inner wall of the support frame 5. An L-shaped connecting rod 42 is fixedly connected to the outer wall of the support column 40. A triangular connecting rod 41 is rotatably connected to the outer wall of the support column 40. A second spring 43 is fixedly connected to the upper surface of the L-shaped connecting rod 42, and a third spring 44 is fixedly connected to the lower surface of the L-shaped connecting rod 42. The second spring 43 and the third spring 44 form an elastic buffer system with upper and lower resistance. A collection box 30 is fixedly connected to the lower surface of the support frame 5. An inclined discharge box 31 is provided on both sides of the collection box 30 to facilitate the automatic sliding out of the iron scrap.
[0023] Specifically, when the waste residue, which includes screened and crushed material, flows through the area below the support frame 5 via the second conveyor belt 24, the iron removal operation is initiated. The first motor 25 drives the rotating column 27 to rotate, causing the magnet 29 and the rotating rod 28 to make circular motions above the conveyor belt. The magnet 29 periodically sweeps across the material layer above, adsorbing iron and carrying it away from the surface of the conveyor belt. At the same time, the rotational power of the rotating column 27 is transmitted to the first sprocket 32 via the second sprocket 33 and the chain 34, and then through the meshing of the third gear 35 and the fourth gear 36, drives the first cleaning roller 37 and the second cleaning roller 39 to rotate in opposite directions. Under the floating support formed by the triangular connecting rod 41 and the second spring 43 and the third spring 44, the cleaning brush head 38 continuously adheres to the surface of the rotating magnet 29 and the rotating rod 28, forcibly brushing off the adsorbed iron. The separated iron falls into the collection box 30 and is finally discharged outside the device through the discharge box 31.
[0024] Please see the appendix Figure 1 - Appendix Figure 9 The crushing assembly includes a horizontally positioned second crushing roller 9, which is rotatably mounted on one side of the inner wall of the processing table 1. A crushing box 3 is fixedly connected to one side of the inner wall of the processing table 1, forming a crushing chamber inside the crushing box 3. A second motor 26 is fixedly connected to one side of the outer wall of the processing table 1 via a bracket. The output end of the second motor 26 passes through the processing table 1 and is fixedly connected to a first crushing roller 8. One end of the first crushing roller 8 passes through the processing table 1 and is fixedly connected to a first gear 6. One end of the second crushing roller 9 passes through the processing table 1 and is fixedly connected to a second gear 7. The teeth of the second gear 7 mesh with the teeth of the first gear 6 to ensure synchronous operation of the two rollers. The crushing box 3 has a feed inlet 10 on the outer wall near the first conveyor belt 23. A hydraulic rod 12 is vertically fixed to the upper side of the inner wall of the crushing box 3. A lower pressure plate 11 is fixedly connected to the output end of the hydraulic rod 12. The size of the lower pressure plate 11 is adapted to the cross-section of the crushing chamber. A telescopic cylinder 13 is fixedly connected to the upper side of the inner wall of the crushing box 3. A first spring 17 is fixedly connected to the inner wall of the telescopic cylinder 13. A telescopic column 14 is fixedly connected to one end of the first spring 17. A limit column 16 is fixedly connected to the outer wall of the telescopic column 14. A limit groove 15 is opened along the axial direction on the outer wall of the telescopic cylinder 13 to limit the rotational freedom of the telescopic column 14.
[0025] Specifically, the coarse material is fed into the feed inlet 10 on the side of the crushing box 3 via the first conveyor belt 23. After the material enters the crushing chamber, the hydraulic rod 12 extends, driving the lower pressure plate 11 to descend vertically and contact the material. During this process, the telescopic column 14 slides along the inner wall of the telescopic cylinder 13, the limiting column 16 moves synchronously along the limiting groove 15, and the first spring 17 undergoes compression deformation with the pressure change, causing the lower pressure plate 11 to force the loose waste to the crushing roller area and pre-compact it. Subsequently, the second motor 26 operates, and through the meshing transmission of the first gear 6 and the second gear 7, it forces the first crushing roller 8 and the second crushing roller 9 to rotate synchronously in opposite directions. The compacted material is rolled into the space between the two rollers, and is mechanically squeezed and broken into small particles. Finally, it passes through the gap between the rollers, is discharged from the bottom of the crushing box 3, and flows into the second conveyor belt 24.
[0026] Please see the appendix Figure 1 - Appendix Figure 8 The tiered screening assembly includes a screening box 2, the lower surface of which is fixedly connected to the upper surface of the processing table 1. The inner wall of the screening box 2 is provided with screening plates 20 arranged in a stepped manner from high to low. There are three screening plates 20. The inner wall of each of the three screening plates 20 is provided with several screening openings 22 of uniform or gradually varying aperture size. The third screening plate 20 is provided with a guide slope facing the first conveyor belt 23. An open-type feed hopper 21 is provided on the upper side of the inner wall of the screening box 2.
[0027] Specifically, industrial waste of mixed particle sizes is fed into screening box 2 by hopper 21. Under the action of gravity, the waste flow rolls down along three stepped screening plates 20. During the rolling process, the material undergoes stratification and screening: fine material smaller than the specified aperture directly penetrates the screening opening 22 on the screening plate 20 and falls vertically onto the second conveyor belt 24 below to form a fine material flow, while coarse material with a larger volume cannot pass through the screening opening 22 and slides continuously along the inclined surface of the screening plate 20 to the end, and is finally guided to the first conveyor belt 23 to form a coarse material flow to be crushed.
[0028] Please see the appendix Figure 1 - Appendix Figure 10A drying box 4 is fixedly connected to the upper surface of the second conveyor belt 24. The drying box 4 is located on the side near the iron removal component, forming a tunnel-type drying structure. Heating wires 19 are provided on both sides of the inner wall of the drying box 4, and heating tubes 18 are provided on the upper side of the inner wall of the drying box 4 to achieve three-dimensional heating. The clean material that has undergone thorough iron removal enters the drying box 4 with the second conveyor belt 24. The heating wires 19 and heating tubes 18 inside the box generate heat to dry the moisture in the waste residue, completing the processing of the raw materials for cement preparation. The rotating rod 28 is fixedly embedded in the inner wall of the rotating rod 28. The rotating rod 28 is arranged in a ring array. The rotating column 27 is rotatably connected to the middle side of the inner wall of the support frame 5. The magnet 29 is rotatably connected between the first cleaning roller 37 and the second cleaning roller 39. The upper end of the connecting rod 41 is rotatably connected to the outer wall of the first cleaning roller 37, and the lower end of the triangular connecting rod 41 is rotatably connected to the outer wall of the second cleaning roller 39. One end of the second spring 43 is fixedly connected to the lower surface of the upper end of the triangular connecting rod 41, and one end of the third spring 44 is fixedly connected to the upper surface of the lower end of the triangular connecting rod 41. The outer wall of the telescopic column 14 is slidably connected to the inner wall of the telescopic cylinder 13, and the outer wall of the limiting column 16 is slidably connected to the inner wall of the limiting groove 15. One end of the telescopic column 14 is fixedly connected to the inner wall of the lower pressure plate 11. The lower pressure plate 11 is set on the inner wall of the crushing box 3. The first crushing roller 8 is set on the lower side of the inner wall of the crushing box 3. The bottom of the crushing box 3 is designed as an opening and is set above the second conveyor belt 24. The second conveyor belt 24 moves in the opposite direction to the first conveyor belt 23.
[0029] Working principle: When the cement preparation device for treating industrial waste slag needs to be used, firstly, the industrial waste slag raw material to be treated is poured into the feed hopper 21 of the stepped screening component. The material falls into the screening box 2 and passes through three screening plates 20 arranged in a stepped manner from high to low. During this process, the waste slag particles with smaller particle size pass directly through the screening opening 22 on the screening plate 20 and fall directly onto the second conveyor belt 24 below, waiting for subsequent processing. The waste slag particles with larger particle size cannot pass through the screening opening 22 and will slide down the stepped screening plate 20 to the end and fall onto the first conveyor belt 23 above through the inclined plane. The first conveyor belt 23 transports large particles of waste to the feed inlet 10 of the crushing component, and the material enters the crushing box 3. At this time, in order to prevent material blockage and assist feeding, the hydraulic rod 12 is activated to extend downward, pushing the lower pressure plate 11 to press the material down. During the pressing process, in order to provide buffer protection and ensure the stability of the movement trajectory, the telescopic column 14 slides inside the telescopic cylinder 13. The first spring 17 inside the telescopic cylinder 13 is compressed by force to play a buffering role. At the same time, the limiting column 16 slides in the limiting groove 15 to prevent the pressing component from shifting or falling off. Next, the second motor 26 starts, and the output end drives the first crushing roller 8 to rotate. The first gear 6 at the end of the first crushing roller 8 meshes with the second gear 7 at the end of the second crushing roller 9, thereby driving the second crushing roller 9 and the first crushing roller 8 to rotate inward relative to each other. The material pressed down by the lower pressure plate 11 is strongly squeezed and crushed between the second crushing roller 9 and the first crushing roller 8. After crushing, the material falls directly from the opening at the bottom of the crushing box 3 onto the second conveyor belt 24 below. At this time, the second conveyor belt 24 carries two parts of material: one part is small particles directly screened by the screening component, and the other part is small particles that fall after being crushed by the crushing component. The second conveyor belt 24 conveys all the material backward to the iron removal station. When the material moves with the second conveyor belt 24 to the support frame 5, the first motor 25 starts and drives the rotating column 27 to rotate continuously. The magnet 29 and the rotating rod 28 rotate synchronously with the rotating column 27. During the rotation, when the magnet 29 rotates to face the conveyor belt, it adsorbs the iron in the waste residue onto the surface. As the magnet 29 continues to rotate away from the conveyor belt surface, it carries the adsorbed iron to the clean area. Meanwhile, the rotating column 27 drives the second sprocket 33 to rotate, which is transmitted to the first sprocket 32 through the chain 34, driving the first cleaning roller 37 to rotate. Since the third gear 35 and the fourth gear 36 mesh, the second cleaning roller 39 also rotates in the opposite direction. During the rotation of the magnet 29, its surface is in constant contact with the rotating cleaning brush head 38. The cleaning brush head 38 quickly scrapes off the iron that has just been attracted on the magnet 29 and the rotating rod 28, realizing continuous operation of "attracting iron, rotating, and cleaning at the same time" to prevent the magnet 29 from becoming saturated. In order to ensure that the brush head is always in close contact with the rotating magnet 29, an L-shaped connecting rod 42 is fixed on the support column 40 in the support frame 5, and a triangular connecting rod 41 is rotatably connected. The upper end of the triangular connecting rod 41 is connected to the L-shaped connecting rod 42 through the second spring 43 and the lower end is connected to the L-shaped connecting rod 42 through the third spring 44. This double-spring floating structure ensures that the cleaning roller can adapt to the small vibration when the magnet 29 rotates and maintain constant pressure. The iron that is brushed off falls into the collection box 30 below and is discharged through the discharge boxes 31 on both sides. The clean material, after thorough iron removal, enters the drying box 4 via the second conveyor belt 24. The heating wire 19 and heating tube 18 inside the box generate heat to dry the moisture in the waste residue, thus completing the processing of the raw materials for cement preparation.
