Description

Technical Field

[0001] This invention relates to the field of slag powder production and recycling technology, specifically to a secondary recycling device based on the blast furnace slag powder production process. Background Technology

[0002] Slag is a byproduct produced during the ironmaking process in blast furnaces. It plays an important role in industrial production, especially in some large factories where slag needs to be ground into slag powder before it can be used. Before entering the grinding process, granulated blast furnace slag needs to be dried.

[0003] Blast furnace granulated slag with high moisture content often tends to stick together. Existing technical solutions mostly involve placing a large amount of blast furnace slag directly inside a drying container, stirring it while increasing the temperature inside the container to dry the slag. However, this method requires continuous stirring of the slag inside the container to ensure that it fully absorbs heat. But because there is a large amount of slag inside the container, it is difficult for the slag to fully absorb heat for drying, which affects the drying effect and reduces the quality of blast furnace slag recovery. Summary of the Invention

[0004] The purpose of this invention is to provide a secondary recycling device based on the blast furnace slag powder production process to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a secondary recycling device based on the blast furnace slag powder production process, comprising a main body and a drying and falling chamber, the drying and falling chamber being fixedly connected to the top of the main body, and further comprising:

[0007] The feeding mechanism is located on the top of the main body. The feeding mechanism includes four support frames, which are fixedly connected to the four corners of the top of the main body. The top of the four support frames is fixedly connected to the feeding chamber, and the bottom inner wall of the feeding chamber is provided with a movable lifting groove.

[0008] The drying mechanism is located on the outer wall of the drying falling chamber. The drying mechanism includes a limiting inlet rotatably connected to the outer wall of the drying falling chamber. The limiting inlet is rotatably connected inside the movable lifting groove. A drying spinning frame is fixedly connected to the bottom of the limiting inlet.

[0009] A closed mechanism is installed at the bottom of the drying and spinning frame. A heated dryer is installed at the bottom of the drying and spinning frame, and a heater is installed inside the heated dryer.

[0010] Furthermore, hydraulic cylinders are fixedly connected to both the front and back of the main body, and a placement plate is fixedly connected to the output end of the two hydraulic cylinders. A collection box is placed on the top of the placement plate at a location corresponding to the main body. Limiting grooves are opened at the central axis of the outer walls on the left and right sides of the main body, and the bottom of the drying and falling chamber is funnel-shaped.

[0011] Furthermore, the feeding mechanism also includes four connecting frames, which are fixedly connected to the top of four support frames respectively.

A gap is left between the feeding chamber and the drying and falling chamber. A motor is fixedly connected to the top of the two support frames near one of the hydraulic cylinders. A gear column is fixedly connected to the output end of the motor.

[0012] Furthermore, the drying mechanism also includes multiple annular groove connecting frames, all of which are fixedly connected to the top of the drying spinning frame. A gear sleeve is fixedly connected to the side of the multiple annular groove connecting frames away from the drying spinning frame, and the gear sleeve is rotatably connected to the outer wall of the drying falling chamber.

[0013] Furthermore, multiple annular groove connecting frames are slidably connected in the gap between the drying drop chamber and the feeding chamber. Multiple scrapers are fixedly connected to the bottom of the drying spinning frame. All scrapers are in contact with the inner wall of the bottom of the drying drop chamber. The gear sleeve meshes with the toothed column at the output end of the motor, and the gear sleeve and the toothed column are slidably connected.

[0014] Furthermore, a pressing mechanism is provided on the side of the multiple annular groove connecting frames away from the gear sleeve. The pressing mechanism includes an annular frame, which is rotatably connected to the side of the multiple annular groove connecting frames away from the gear sleeve. Two rising slides are fixedly connected to the top of the annular frame. The two rising slides are slidably connected to the inside of two limiting slides respectively. A pressing plate is fixedly connected to the bottom of the two rising slides.

[0015] Furthermore, an upper push plate is fixedly connected to both ends of the top of the lower pressure plate near the two rising slides. A rotating slide is rotatably connected to the top of the upper push plate. A strip-shaped perforated frame is slidably connected to the outer wall of the rotating slide. A push-pull strip is fixedly connected to the end of the strip-shaped perforated frame away from the upper push plate. The connection between the strip-shaped perforated frame and the push-pull strip is slidably connected to the two sliding grooves between the two connecting frames. A closed lower pressure frame is rotatably connected between the two push-pull strips. The bottom of the closed lower pressure frame is fitted into the top inlet of the feed chamber.

[0016] Furthermore, the sealing mechanism also includes a push column, which is fixedly connected to the center of the top of the lower pressure plate. The bottom of the heating dryer is fixedly connected to the top of the push column. Multiple limiting brackets are fixedly connected to the outer wall of the push column, and a sealing ring is fixedly connected to the top of the multiple limiting brackets.

[0017] Furthermore, a shrinkage annular groove is provided at a location on the top of the heated dryer away from the center. A sealing ring is fitted inside the shrinkage annular groove, and multiple limiting supports slide through into the shrinkage annular groove. The top of the heated dryer and the bottom of the drying spinning frame are used in conjunction.

[0018] The present invention has the following beneficial effects:

[0019] (1) In this invention, when the slag is dried between the drying spinning frame and the heating dryer, the meshing of the gear column at the motor output end and the gear sleeve causes the gear sleeve to rotate on the outer wall of the drying drop chamber when the motor starts. Multiple annular groove connecting frames then drive the drying spinning frame to rotate synchronously inside the drying drop chamber, making the blast furnace granulated slag between the drying spinning frame and the heating dryer more evenly dispersed, thus improving the slag drying effect. Furthermore, when the blast furnace granulated slag loses its stickiness after drying, it becomes even looser between the drying spinning frame and the heating dryer. The rotation of the drying spinning frame further grinds the blast furnace granulated slag, making the blast furnace granules... As the slag gradually decreases in size, it eventually slides into the bottom of the drying chamber through the fixed gap between the drying spinning frame and the heating dryer. This replaces the method of constantly stirring the slag inside the container to ensure it fully absorbs heat. By allowing some slag to enter between the drying spinning frame and the heating dryer, the rotation of the drying spinning frame makes the slag more evenly dispersed, increasing the contact area between the slag and the heated dryer. This increases the amount of heat absorbed by the slag, improving the drying effect and enhancing the quality of blast furnace slag recovery.

[0020] (2) In this invention, the device is placed below the conveying device. The conveying device transports the blast furnace granulated slag with high moisture content into the feeding rack. The blast furnace granulated slag then enters the feeding chamber between the limiting feeding port and the heating dryer. The hydraulic cylinder retracts towards the placement plate, causing the main body to descend. The lower pressure plate abuts against the top of the placement plate, driving the rising slide to slide upward inside the limiting slide groove. Through the connection between the ring frame and multiple annular groove connecting frames, the gear sleeve moves upward, causing the limiting feeding port to move upward inside the movable lifting groove, so that the top outer wall of the heating dryer is aligned with the drying spinning frame. The increased distance between them allows the blast furnace granulated slag entering the limited feed inlet to pass between the drying spinning frame and the heating dryer. This causes the bottom of the drying spinning frame and the top of the heating dryer to compress the blast furnace granulated slag between them, separating and crushing any slag that is stuck together. The heating device inside the heating dryer raises the surface temperature of the dryer, further heating and drying the blast furnace slag dispersed between the drying spinning frame and the heating dryer. This prevents the damp slag from sticking together and affecting the drying efficiency, thus improving the practicality of the device.

[0021] (3) During the drying process, the inlet of the closed lower pressure frame and the feed chamber of this invention is open. As the distance between the drying spinning frame and the heating dryer increases, the lower pressure plate will push the upper push plate to rise synchronously. Through the rotational connection between the upper push plate and the rotating slide, the strip-shaped hole frame is pushed to rotate inside the sliding groove on the connecting frame, so that the rotating slide slides inside the strip-shaped hole on the strip-shaped hole frame, causing the strip-shaped hole frame to tilt up, causing the push-pull bar to press down. The connection between the strip-shaped hole frame and the push-pull bar will slide towards the end of the closed lower pressure frame inside the sliding groove. Through the rotational connection between the two push-pull bars and the top of the closed lower pressure frame, the closed lower pressure frame is pressed down, so that it is sealed with the top of the feed chamber. During the pressing down of the closed lower pressure frame, the slag that has entered the feed chamber will be squeezed, so that the slag inside the feed chamber can enter between the drying spinning frame and the heating dryer, avoiding the difficulty of entering between the drying spinning frame and the heating dryer due to the sticky slag sticking together.

[0022] (4) During the process of pushing down the pressure plate, the limit stop frame is simultaneously driven by the push column to slide up inside the sliding hole opened through the bottom of the heating dryer, and pushes the sealing stop ring to move up inside the shrinking annular groove. This can block the outlet between the heating dryer and the drying spinning frame, preventing the slag that has not been dried from falling below the heating dryer, thus improving the quality of slag drying. After the dried slag falls to the bottom of the rising slide frame, it falls into the collection box placed at the bottom of the main body through the funnel-shaped bottom of the drying drop chamber. When the gear sleeve rotates, it simultaneously drives the scraper to scrape the inner wall of the bottom of the drying drop chamber, removing the slag powder adsorbed on the inner wall of the bottom of the drying drop chamber. At the same time, it prevents the slag that has been dried from falling too much and causing blockage at the outlet of the drying drop chamber.

[0023] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] 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.

[0036] Example 1, please refer to Figures 1-8 As shown, the present invention is a secondary recycling device based on the blast furnace slag powder production process, including a main body 1 and a drying and falling chamber 102, the drying and falling chamber 102 being fixedly connected to the top of the main body 1, and further including:

[0037] Feeding mechanism 2 is located on the top of main body 1. Feeding mechanism 2 includes four support frames 201, which are fixedly connected to the four corners of the top of main body 1. Feeding chamber 204 is fixedly connected to the top of the four support frames 201. Movable lifting groove 206 is opened on the bottom inner wall of feeding chamber 204. Feeding mechanism 2 also includes four connecting frames 202, which are fixedly connected to the top of the four support frames 201. Sliding groove 203 is opened between every two connecting frames 202. Feeding frame 205 is fixedly connected to the top of feeding chamber 204. A gap is left between feeding chamber 204 and drying falling chamber 102. Motor 207 is fixedly connected to the top of two support frames 201 near one of the hydraulic cylinders 103. Gear column is fixedly connected to the output end of motor 207.

[0038] Drying mechanism 3 is located on the outer wall of drying duct 102. Drying mechanism 3 includes a limiting inlet 301 rotatably connected to the outer wall of drying duct 102. The limiting inlet 301 is rotatably connected inside the movable lifting groove 206. A drying spinning frame 302 is fixedly connected to the bottom of the limiting inlet 301. Drying mechanism 3 also includes multiple annular groove connecting frames 303, all fixedly connected to the top of the drying spinning frame 302. A gear sleeve 304 is fixedly connected to the side of the multiple annular groove connecting frames 303 away from the drying spinning frame 302. The gear sleeve 304 is rotatably connected to the outer wall of drying duct 102. The multiple annular groove connecting frames 303 are slidably connected in the gap between drying duct 102 and inlet cavity 204. Multiple scrapers 305 are fixedly connected to the bottom of the drying spinning frame 302, and the scrapers 305 are in contact with the inner wall of the bottom of drying duct 102. The gear sleeve 304 is connected to the motor 207. The output end gear sprocket meshes, and the gear sleeve 304 is slidably connected to the gear sprocket. When the slag is dried between the drying spinning frame 302 and the heating dryer 504, the gear sleeve 304 is meshed with the output end gear sprocket of the motor 207. When the motor 207 starts, it drives the gear sleeve 304 to rotate on the outer wall of the drying falling chamber 102. Through multiple annular groove connecting frames 303, it drives the drying spinning frame 302 to rotate synchronously inside the drying falling chamber 102, so that the drying spinning frame 302... The blast furnace granulated slag between the drying spinner 302 and the heating dryer 504 is more evenly dispersed. When the blast furnace granulated slag loses its stickiness after drying, it will become looser between the drying spinner 302 and the heating dryer 504. Then, the blast furnace granulated slag is ground by the rotation of the drying spinner 302, so that the size of the blast furnace granulated slag gradually becomes smaller. Finally, it slides into the bottom of the drying drop chamber 102 through the gap between the drying spinner 302 and the heating dryer 504 at a fixed distance.

[0039] The sealing mechanism 5 is located at the bottom of the drying and spinning frame 302. A heating dryer 504 is installed at the bottom of the drying and spinning frame 302, and a heater is installed inside the heating dryer 504. The sealing mechanism 5 also includes a push column 501, which is fixedly connected to the top center of the lower pressure plate 403. The bottom of the heating dryer 504 is fixedly connected to the top of the push column 501. Multiple limiting brackets 502 are fixedly connected to the outer wall of the push column 501, and a sealing ring 503 is fixedly connected to the top of each limiting bracket 502. A shrinkage annular groove 505 is formed at a point on the top of the heating dryer 504 away from the center. The sealing ring 503 and the shrinkage... The annular groove 505 is fitted inside, and multiple limiting brackets 502 slide through into the shrinking annular groove 505. The top of the heating dryer 504 and the bottom of the drying spinning frame 302 are used in conjunction. The bottom of the drying spinning frame 302 and the top of the heating dryer 504 squeeze the blast furnace granulated slag between the heating dryer 504 and the drying spinning frame 302, so that the blast furnace granulated slag that is stuck together is separated and crushed. The heating device inside the heating dryer 504 raises the surface temperature of the heating dryer 504, thereby heating and drying the blast furnace slag dispersed between the drying spinning frame 302 and the heating dryer 504.

[0040] Hydraulic cylinders 103 are fixedly connected to both the front and back of the main body 1. A placement plate 104 is fixedly connected to the output ends of the two hydraulic cylinders 103. A collection box is placed on the top of the placement plate 104, corresponding to a point on the main body 1. Limiting grooves 101 are provided on the central axis of the outer walls on the left and right sides of the main body 1. The bottom of the drying descent chamber 102 is funnel-shaped. The hydraulic cylinders 103 retract towards the placement plate 104, causing the main body 1 to descend. The lower pressure plate 403 abuts against the top of the placement plate 104, causing it to rise. The slide 402 slides upward inside the limiting slide groove 101, thereby driving the gear sleeve 304 to move upward as a whole through the connection between the ring frame 401 and multiple ring groove connecting frames 303, so that the limiting feed port 301 moves upward inside the movable lifting groove 206, and the distance between the top outer wall of the heating dryer 504 and the drying spinning frame 302 increases, so that the blast furnace granulated slag that enters the limiting feed port 301 can enter between the drying spinning frame 302 and the heating dryer 504;

[0041] A pressing mechanism 4 is provided on the side of the multiple annular groove connecting frame 303 away from the gear sleeve 304. The pressing mechanism 4 includes an annular frame 401, which is rotatably connected to the side of the multiple annular groove connecting frame 303 away from the gear sleeve 304. Two rising slides 402 are fixedly connected to the top of the annular frame 401. The two rising slides 402 are slidably connected to the inside of two limiting slide grooves 101 respectively. A pressing plate 403 is fixedly connected to the bottom of the two rising slides 402. The top of the pressing plate 403 is close to both ends of the two rising slides 402. An upper push plate 404 is fixedly connected to each of the two connecting frames 202. A rotating slide 405 is rotatably connected to the top of the upper push plate 404. A strip-shaped perforated frame 406 is slidably connected to the outer wall of the rotating slide 405. A push-pull strip 407 is fixedly connected to one end of the strip-shaped perforated frame 406 away from the upper push plate 404. The connection between the strip-shaped perforated frame 406 and the push-pull strip 407 is slidably connected to the two sliding grooves 203 between the two connecting frames 202. A closed lower pressure frame 408 is rotatably connected between the two push-pull strips 407. The bottom of the closed lower pressure frame 408 is connected to the top inlet of the feed chamber 204. When the inlet of the lower pressure frame 408 and the feed chamber 204 are open, and the distance between the drying spin press frame 302 and the heating dryer 504 increases, the lower pressure plate 403 will simultaneously push the upper push plate 404 upward. The upper push plate 404 is rotatably connected to the rotating slide 405, pushing the strip-shaped perforated frame 406 to rotate inside the sliding groove 203 on the connecting frame 202. This causes the rotating slide 405 to slide inside the strip-shaped holes on the strip-shaped perforated frame 406, causing the strip-shaped perforated frame 406 to tilt upward, thus pressing down the push-pull strip 407. The connection between the strip-shaped perforated frame 406 and the push-pull strip 407 will slide towards one end of the closed lower pressure frame 408 inside the sliding groove 203. Through the rotational connection between the two push-pull strips 407 and the top of the closed lower pressure frame 408, the closed lower pressure frame 408 will be pressed down, sealing it against the top of the feed chamber 204. During the pressing process of the closed lower pressure frame 408, the slag that has entered the feed chamber 204 will be squeezed, making it easier for the slag in the feed chamber 204 to enter between the drying spinning frame 302 and the heating dryer 504.

[0042] In use, the device is placed below the conveying device. The conveying device transports the blast furnace granulated slag with high moisture content to the inside of the feeding rack 205. Then, the blast furnace granulated slag enters the space between the limiting inlet 301 and the heating dryer 504 through the feeding chamber 204. The hydraulic cylinder 103 retracts towards the placement plate 104, causing the main body 1 to descend as a whole. The lower pressure plate 403 abuts against the top of the placement plate 104, driving the rising slide 402 to slide upward inside the limiting slide groove 101. Through the connection between the annular frame 401 and multiple annular groove connecting frames 303, the gear sleeve 304 moves upward as a whole, so that the limiting inlet 301 is inside the movable lifting groove 206. The upward movement increases the distance between the top outer wall of the heating dryer 504 and the drying spinning frame 302, allowing the blast furnace granulated slag entering the limiting feed inlet 301 to enter between the drying spinning frame 302 and the heating dryer 504. This causes the bottom of the drying spinning frame 302 and the top of the heating dryer 504 to compress the blast furnace granulated slag between the heating dryer 504 and the drying spinning frame 302, separating and crushing the slag that is stuck together. The heating device inside the heating dryer 504 raises the surface temperature of the heating dryer 504, thereby heating and drying the blast furnace slag dispersed between the drying spinning frame 302 and the heating dryer 504.

[0043] Example 2, please refer to Figures 1-8 As shown, during use, when the slag is dried between the drying spinning frame 302 and the heating dryer 504, the gear sleeve 304 is driven to rotate on the outer wall of the drying chamber 102 by the meshing of the gear column at the output end of the motor 207. This rotation, via multiple annular groove connecting frames 303, causes the drying spinning frame 302 to rotate synchronously inside the drying chamber 102, resulting in a more uniform dispersion of the blast furnace granulated slag between the drying spinning frame 302 and the heating dryer 504. Furthermore, as the blast furnace granulated slag loses its stickiness after drying, it becomes even looser between the drying spinning frame 302 and the heating dryer 504, and then... The rotating dryer spun mill 302 grinds the blast furnace granulated slag, gradually reducing the size of the granulated slag. Finally, the slag slides into the bottom of the drying chamber 102 through the gap between the dryer spun mill 302 and the heated dryer 504. This replaces the method of constantly stirring the slag inside the container to allow the slag to fully absorb heat. By allowing some slag to enter between the dryer spun mill 302 and the heated dryer 504, the rotation of the dryer spun mill 302 makes the slag between the dryer spun mill 302 and the heated dryer 504 more evenly dispersed, increasing the contact area between the slag and the heated dryer 504.

[0044] During the drying process, the inlet of the closed lower pressure frame 408 and the feed chamber 204 is open. As the distance between the drying spinning frame 302 and the heated dryer 504 increases, the lower pressure plate 403 simultaneously pushes the upper push plate 404 upward. The upper push plate 404 is rotatably connected to the rotating slide 405, pushing the strip-shaped perforated frame 406 to rotate within the sliding groove 203 on the connecting frame 202. This causes the rotating slide 405 to slide within the strip-shaped holes on the strip-shaped perforated frame 406, causing the strip-shaped perforated frame 406 to tilt upward, thus pressing down the push-pull bar 407. The strip-shaped perforated frame 406 and the push-pull bar 407... The connection point will slide towards the end of the closed pressure frame 408 inside the sliding groove 203. It is rotated to the top of the closed pressure frame 408 through two push-pull strips 407, which drives the closed pressure frame 408 to press down, so as to seal it with the top of the feed chamber 204. During the pressing process of the closed pressure frame 408, it will squeeze the slag that has entered the feed chamber 204, so that the slag inside the feed chamber 204 can enter between the drying spinning frame 302 and the heating dryer 504, and avoid the difficulty of entering the drying spinning frame 302 and the heating dryer 504 due to the sticky slag sticking together.

[0045] During the upward push of the lower pressure plate 403, the push column 501 simultaneously drives the limiting abutment 502 to slide upward inside the sliding hole that runs through the bottom of the heating dryer 504, pushing the sealing abutment 503 to move upward inside the shrinking annular groove 505. This can block the outlet between the heating dryer 504 and the drying spinning frame 302, preventing undried slag from falling below the heating dryer 504, thus improving the quality of slag drying. After the dried slag falls to the bottom of the rising slide 402, it falls into the collection box placed at the bottom of the main body 1 through the funnel-shaped bottom of the drying falling chamber 102 for collection. When the gear sleeve 304 rotates, it simultaneously drives the scraper 305 to scrape the inner wall of the bottom of the drying falling chamber 102, removing the slag powder adsorbed on the inner wall of the bottom of the drying falling chamber 102.
