Description

Technical Field

[0001] The invention belongs to the technical field of metallurgical slag recovery, in particular to a metallurgical slag recovery device and a method thereof. Background Art

[0002] Metallurgical slag is solid waste discharged during the steelmaking process. It is mainly composed of various oxides formed by oxidation of impurities such as silicon, manganese, phosphorus, and sulfur in pig iron during the smelting process, as well as salts generated by the reaction of these oxides with solvents. Steel slag can be comprehensively utilized as a secondary resource. First, it can be recycled as a smelting solvent in the factory, and it can also replace limestone; another is as a raw material for manufacturing road construction materials, building materials or agricultural fertilizers. In addition, steel slag can also be used to manufacture microcrystalline glass, etc.

[0003] In the recycling process of existing metallurgical slag, the initial physical treatment is the first crucial step. The metallurgical slag is sent to the crusher for crushing. This process uses mechanical force to break large and hard waste slag into smaller particles, increasing its surface area and providing convenience for subsequent operations. The crushed metallurgical slag particles are more uniform in size, which is conducive to subsequent screening operations; then, the crushed metallurgical slag enters the screening equipment and is graded by screens with different apertures to classify the particles according to size. The screening process not only removes large impurities in the waste slag, but also enables particles of different particle sizes to be processed separately in the subsequent processing process; finally, the screened metallurgical slag particles may also need to be mixed to ensure the uniformity of their composition. The mixing process uses stirring or other mechanical means to fully mix metallurgical slag particles of different batches or properties to prepare for subsequent hydrometallurgical or pyrometallurgical treatment; However, in the process of using the existing crusher, because the waste slag is large and hard, although the large and hard waste slag is wetted before crushing to reduce the dust raised during the crushing process, the inside of the waste slag cannot be wetted, resulting in a large amount of metal dust in the crushing process. The raised metal dust will affect the surrounding working environment and cause harm to the health of the staff. At the same time, after the crushed waste slag is collected, it is still necessary to conduct separate screening, which leads to a long waste slag recovery process and low waste slag recovery efficiency.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0021] like Figures 1 to 6 As shown, a metallurgical slag recovery device and method described in an embodiment of the present invention include a base platform, a plurality of support rods are fixedly connected to the upper surface of the base platform, a same support frame is fixedly connected to the upper surface of the support frame, a fixed frame is fixedly connected to the upper surface of the support frame, a first cavity is opened inside the fixed frame, two groups of drive components are fixedly connected to the upper surface of the support frame, each group of drive components includes a first motor fixedly connected to the support frame, the output end of each first motor is transmission-connected to a first strip steel, each group of drive components drives a crushing roller through the first strip steel, a plurality of iron blocks are fixedly connected to the circumferential surface of each crushing roller, the two crushing rollers are used for crushing metallurgical slag, a spray component is arranged on the upper surface of the fixed frame, the spray component includes a storage box fixedly connected to the upper surface of the fixed frame, a pressure pump is fixedly connected to the upper surface of the storage box, a plurality of spray holes are opened at the position of the fixed frame corresponding to the storage box, and the spray holes are used for spraying water mist.

[0022] Specifically, in the process of using the existing crusher, because the waste residue is large and hard, although the large and hard waste residue is wetted before crushing to reduce the dust raised during the crushing process, the interior of the waste residue cannot be wetted, resulting in a large amount of metal dust in the crushing process. The raised metal dust will affect the surrounding working environment and cause harm to the health of the staff. At the same time, after the waste residue is collected after crushing, it is necessary to perform separate screening, resulting in a long waste residue recovery process and low waste residue recovery efficiency. Therefore, the present invention solves this problem by setting a certain structure. When the metallurgical slag recovery device is used, the collected metallurgical slag is first inverted into the first cavity of the storage box. After being inverted into the first cavity, the two first motors on the support frame can be started. After being started, the two first motors respectively drive the first strips of steel connected to each other, and each first strip of steel can drive the crushing rollers controlled by each other to rotate. After the two crushing rollers controlled by each other rotate toward each other, the iron blocks on the circumferential surface of the crushing rollers can crush the metallurgical slag. While the crushing rollers crush the metallurgical slag, the spray assembly on the upper surface of the fixed frame is started. First, the pressure pump on one side of the storage box is started. After the pressure pump is started, the water in the storage box is pressurized. The pressurized water is sprayed from a plurality of spray holes on one side of the storage box close to the fixed frame. The water mist sprayed from the spray holes directly acts on the metallurgical slag being crushed, thereby performing dust reduction treatment on the dust generated by the crushing, achieving the effect of reducing the dust, and protecting the working environment around the metallurgical recovery device. The problem that a large amount of metal dust will be generated during the crushing process because the inside of the waste slag cannot be moistened is solved. The raised metal dust will affect the surrounding working environment and cause harm to the health of the workers.

[0023] like Figure 2 As shown, the upper surface of the storage box of this embodiment is threadedly connected with a sealing cover, and the upper surface of the sealing cover is provided with a plurality of vertical lines, which are used to prevent the sealing cover from slipping. The sealing cover is used to add water into the storage box.

[0024] Specifically, the sealing cover and the storage box are tightly combined through a threaded connection to ensure that the internal water does not leak. The vertical lines on the sealing cover make it easier to add water to the storage box when the water in the storage box is too much and needs to be refilled.

[0025] like Figure 3 As shown, the upper surface of the fixed frame of this embodiment is fixedly connected with a first guide rail, a first guide groove is provided inside the first guide rail, a first guide plate is slidably connected in the first guide groove, the first guide plate is made of rubber, and is used to seal the feed port of the fixed frame.

[0026] Specifically, by installing a first guide rail on the fixed frame and a first guide groove therein, the first guide plate made of rubber works ingeniously together. When the feed port of the fixed frame needs to be sealed, the first guide plate slides along the first guide groove. The flexibility and sealing properties of the rubber material tightly fit the edge of the feed port, effectively preventing the dust raised upward from the inside from quickly escaping to the external environment. This not only improves the sealing effect and prevents excessive leakage of dust or pollution of the surrounding working environment, but also simplifies the sealing operation through the sliding of the guide plate and the guide rail, thereby improving work efficiency and equipment flexibility. Embodiment 2

[0027] like Figures 1 to 6 As shown, compared with Example 1, another implementation of the present invention is: a guide plate is fixedly connected to the upper surface of the base, the guide plate is located directly below the fixed frame, a protective frame is fixedly connected to the upper surface of the base, the protective frame is used to prevent the metallurgical slag from overflowing when falling, a first trough body is opened on both sides of the guide plate, a screening assembly is arranged in each first trough body, the screening assembly includes a screening plate slidably arranged on the inner wall of the protective frame, a plurality of sieve holes are opened on the upper surface of the screening plate, and the sieve holes can screen the metallurgical slag.

[0028] Specifically, when the metallurgical slag is crushed into powder by the crushing roller, the crushed metallurgical slag will fall onto the guide plate fixed on the upper surface of the base, and the guide plate is fixed on the base at an angle. Before the metallurgical slag powder falls onto the guide plate, it will first fall onto the screening plate, and the screening plate performs screening through a plurality of sieve holes opened on its upper surface, thereby achieving the effect of convenient screening, simplifying the metallurgical recovery workflow, improving the metallurgical work efficiency, and increasing the production volume of metallurgical recovery; The invention solves the problem that after the crushed waste residue is collected, it is still necessary to carry out separate screening, which leads to a long waste residue recovery process and low waste residue recovery efficiency.

[0029] like Figure 6 As shown, in this embodiment, second motors are fixedly connected to both sides of the guide plate, and the output end of the second motor is fixedly connected to the first gear. Each first gear is arranged in the first slot body, and each first gear is drivingly connected to the second steel strip. A cleaning roller is rotatably connected between the two second steel strips, and a plurality of hard rubber cones are fixedly connected to the circumferential surface of the cleaning roller. The cleaning roller is used for clearing the metallurgical slag stuck on the screening plate.

[0030] Specifically, the second motor on both sides of the guide plate drives the first gear to rotate in the preset first slot, thereby driving the second steel strip to rotate at the same time, and then the two second steel strips can drive the cleaning roller to rotate along the screening plate. Because the several hard rubber cones fixed on the surface of the cleaning roller, through their unique conical structure and the flexibility of hard rubber, can penetrate into the screen holes of the screening plate blocked by metallurgical slag, effectively dredge and clean the accumulated metallurgical slag, improve the screening efficiency, reduce the tediousness and cost of manual cleaning, and ensure the continuous and stable operation of the production line through automated operations, reduce the risk of downtime due to blockage, and improve the recovery efficiency of metallurgical slag.

[0031] like Figure 6 As shown, in this embodiment, a rotating shaft is fixedly connected between the two second steel strips, a torsion spring is sleeved on the circumferential surface of the rotating shaft, a fixed tube is fixedly connected to the circumferential surface of the torsion spring, a fixed plate is fixedly connected to the circumferential surface of the fixed tube, a second groove body is opened on the surface of the fixed plate, and a cleaning roller is rotatably connected in the second groove body.

[0032] Specifically, when the rotating shaft drives the torsion spring and the fixed tube to rotate, the cleaning roller rotates freely in the second groove body, close to the lower surface of the screen plate to be cleaned for dredging, and the elastic potential energy of the torsion spring reserves reset energy. During the cleaning process, these reset energies will make the cleaning roller close to the lower surface of the screen plate. When the cleaning is completed, the cleaning roller can quickly return to its initial position, which is convenient for the next cleaning operation, improves the cleaning efficiency, reduces manual intervention, and extends the service life of the cleaning roller through the self-resetting mechanism of the torsion spring, reducing maintenance costs. In addition, the fixed connection between the fixed plate and the fixed tube ensures the stability of the overall structure, making the cleaning process smoother.

[0033] like Figure 6 As shown, a scraper is fixedly connected to the circumferential surface of the fixed tube of this embodiment, and the scraper is used to clean and scrape off metallurgical dirt adhered to the surface of the guide plate. Two groups of compression springs are fixedly connected to the upper surface of the screening plate, and inclined plates are fixedly connected to the position of each group of compression springs in the protection frame. Each inclined plate is fixedly connected to a number of compression springs, and a telescopic rod is arranged inside each compression spring. The bottom end of the telescopic rod is fixedly connected to the screening plate, and the top end of the telescopic rod is fixedly connected to the inclined plate. Two protective plates are fixedly connected to the upper surface of the screening plate, and the protective plates are used to protect the compression springs to prevent metallurgical slag from entering the compression springs.

[0034] Specifically, the scraper design on the fixed pipe is used to scrape off the metallurgical dirt on the surface of the guide plate, which effectively prevents the accumulation of dirt and ensures the efficient operation and long life of the guide plate. At the same time, the combination of the compression spring on the screening plate and the inclined plate and telescopic rod forms a set of efficient shock absorption and buffering mechanisms. During the screening process, the impact force generated by the metallurgical slag on the screening plate is effectively absorbed by the compression spring and converted into elastic potential energy, and then smoothly released through the guidance of the telescopic rod. This not only protects the screening plate from direct impact, but also ensures the stability of the screening process. The setting of the protective plate effectively prevents the metallurgical slag from falling into the compression spring, further extending the service life of the compression spring. At the same time, the up and down shaking of the screening plate can make the screening plate have an automatic shaking effect. By setting the scraper and compression spring shock absorption system, not only the cleaning and screening efficiency is improved, but also the screening quality is improved.

[0035] like Figure 4 As shown, in this embodiment, a positioning box is fixedly connected to one side of the base near the guide plate, a partition is fixedly connected to the middle of the positioning box, a first storage slot is opened on one side of the partition, a second storage slot is opened on the other side of the partition, and a guide frame is fixedly connected to the position of the guide plate corresponding to the first storage slot.

[0036] Specifically, the internal space of the positioning box is divided into a first storage tank and a second storage tank by the positioning box and the partitions inside it, thereby realizing the function of classified storage. The setting of the guide frame allows the metallurgical slag that is not fully ground on the screening plate to enter the first storage tank for subsequent processing or collection, and then the screened dust flows along the guide plate into the second storage tank, thereby achieving the effect of classified collection.

[0037] A metallurgical slag recovery method, applied to a metallurgical slag recovery device according to any one of claims 1 to 8, Step 1: Crushing: The mechanical force of the crusher is used to crush large, hard waste slag into smaller particles, which increases its surface area. The size of the crushed metallurgical slag particles is more uniform, which is convenient for subsequent screening operations; Step 2: Screening: The crushed metallurgical slag enters the screening equipment and is graded through screens with different apertures to classify the particles according to their size. The screening process not only removes large impurities in the waste slag, but also enables particles of different sizes to be processed separately in the subsequent processing process; Step 3: Mixing and metallurgy: The screened metallurgical slag particles need to be mixed. The mixing process uses mechanical means of stirring to fully mix metallurgical slag particles of different batches or different properties, and then hydrometallurgy is carried out to obtain relatively pure metal.

[0038] Preferably, the crushing in step one is specifically as follows: pouring the metallurgical slag into the first cavity of the fixed frame, starting two sets of first motors, driving two crushing rollers to crush the metallurgical slag, and in the process of crushing the metallurgical slag, starting the pressure pump to pressurize the storage box, so that the water in the storage box is sprayed out through the spray hole in the form of mist water, and the crushed metallurgical slag falls onto the screening plate, and is screened by the screening plate, and the metallurgical slag is respectively collected into the positioning boxes.

[0039] Working principle: when the metallurgical slag recovery device is used, the collected metallurgical slag is first inverted into the first cavity of the storage box. After inverted into the first cavity, the two first motors on the support frame can be started. After starting, the two first motors respectively drive the first strips of steel connected to each other, and each first strip of steel can drive the crushing rollers controlled by each other to rotate. After the two crushing rollers controlled by each other rotate toward each other, the iron blocks on the circumferential surface of the crushing rollers can crush the metallurgical slag. While the crushing rollers crush the metallurgical slag, the spray assembly on the upper surface of the fixed frame is started. First, the pressure pump on one side of the storage box is started. After the pressure pump is started, the water in the storage box will be pressurized. The pressurized water is sprayed from a plurality of spray holes on the side of the storage box close to the fixed frame. The water mist sprayed from the spray holes will directly act on the metallurgical slag being crushed, thereby reducing the dust generated by the crushing, achieving the effect of reducing the dust, and protecting the working environment around the metallurgical recovery device. When the metallurgical slag is crushed into powder by the crushing roller, the crushed metallurgical slag will fall onto the guide plate fixed on the upper surface of the base, which is tilted and fixed on the base. Before the metallurgical slag powder falls onto the guide plate, it will first fall onto the screening plate. The screening plate performs screening through a number of sieve holes on its upper surface, thereby achieving a convenient screening effect, simplifying the metallurgical recovery workflow, improving the metallurgical work efficiency, and increasing the production of metallurgical recovery; Then, the second motor on both sides of the guide plate drives the first gear to rotate in the preset first slot, thereby driving the second steel strip to rotate at the same time, and then the two second steel strips can drive the cleaning roller to rotate along the screening plate. Because the several hard rubber cones fixed on the surface of the cleaning roller, through their unique conical structure and hard rubber flexibility, can penetrate into the screen holes of the screening plate blocked by metallurgical slag, effectively dredge and clean the accumulated metallurgical slag, improve the screening efficiency, reduce the tediousness and cost of manual cleaning, and ensure the continuous and stable operation of the production line through automated operations, reduce the risk of downtime due to blockage, and improve the recovery efficiency of metallurgical slag; When the rotating shaft drives the torsion spring and the fixed tube to rotate, the cleaning roller rotates freely in the second groove body and dredges the lower surface of the screen plate to be cleaned. The elastic potential energy of the torsion spring reserves the reset energy. During the cleaning process, the reset energy makes the cleaning roller close to the lower surface of the screen plate. When the cleaning is completed, the cleaning roller can quickly return to the initial position, which is convenient for the next cleaning operation, improves the cleaning efficiency, reduces manual intervention, and extends the service life of the cleaning roller through the self-reset mechanism of the torsion spring, reducing maintenance costs. In addition, the fixed connection between the fixed plate and the fixed tube ensures the stability of the overall structure, making the cleaning process more stable. Finally, the scraper design on the fixed pipe is used to scrape off the metallurgical dirt on the surface of the guide plate, which effectively prevents the accumulation of dirt and ensures the efficient operation and long life of the guide plate. At the same time, the combination of the compression spring on the screening plate, the inclined plate and the telescopic rod forms a set of efficient shock absorption and buffering mechanisms. During the screening process, the impact force generated by the metallurgical slag on the screening plate is effectively absorbed by the compression spring and converted into elastic potential energy, and then released smoothly through the guidance of the telescopic rod. This not only protects the screening plate from direct impact, but also ensures the stability of the screening process. The setting of the protection plate effectively prevents the metallurgical slag from falling into the compression spring, further extending the service life of the compression spring. At the same time, the up and down shaking of the screening plate can make the screening plate have an automatic shaking effect. By setting the scraper and compression spring shock absorption system, not only the cleaning and screening efficiency is improved, but also the screening quality is improved. In addition, the sealing cover and the storage box are tightly combined through the threaded connection to ensure that the internal water does not leak. The vertical lines on the sealing cover make it easier to add water to the storage box when the water in the storage box is too much. And by installing a first guide rail on the fixed frame and a first guide groove therein, the first guide plate made of rubber works ingeniously. When the feed port of the fixed frame needs to be sealed, the first guide plate slides along the first guide groove. The flexibility and sealing of the rubber material fits tightly to the edge of the feed port, effectively preventing the dust raised upward from the inside from quickly escaping to the external environment. This not only improves the sealing effect and prevents excessive leakage of dust or pollution of the surrounding working environment, but also simplifies the sealing operation through the sliding of the guide plate and the guide rail, thereby improving work efficiency and equipment flexibility.
