Description
Technical Field
[0001] This invention relates to the field of iron removal technology, and in particular to a hot slag iron removal device. Background Technology
[0002] Steel slag is a waste product generated by steel plants during the steelmaking process. The main components of steel slag are calcium oxide, magnesium oxide, metallic iron, and manganese oxide. The iron and other components in steel slag can be separated through the hot quenching process. After hot quenching, the iron in the hot quenched slag can be extracted by an iron remover for secondary use.
[0003] A patent application with publication number CN107930846A discloses a permanent magnet separator with explosion-proof function, including a permanent magnet separator body, a pulley at the bottom of the permanent magnet separator body, and a belt sleeved on the outside of the pulley. A permanent magnet rod is connected to the bottom of the permanent magnet separator body, and a discharge arc groove is opened on the belt. Connecting plates are fixedly installed at both ends of the permanent magnet rod. The pulley rotates, driving the belt to move, and the movement of the belt causes the iron adsorbed on the belt to move.
[0004] Since the belt material is usually rubber, polyurethane, polyurethane / rubber composite material, etc., the iron blocks in the hot slag are irregular in shape. When the iron blocks are attracted to the belt by magnetic force, there is a problem of belt wear. In addition, for some sharp iron blocks, there is a possibility of belt puncture when the iron blocks are attracted to the belt. However, belt replacement is troublesome, and frequent belt replacement will affect the efficiency of iron removal from hot slag. Summary of the Invention
[0005] Therefore, the technical problem to be solved by the present invention is to overcome the limitations of the prior art.
[0006] To solve the above-mentioned technical problems, the present invention provides a hot slag iron remover, including a frame, and further comprising: a magnetic source for generating magnetic force, the magnetic source being installed in the middle of the frame; two driving wheels rotatably mounted on the frame, the two driving wheels being symmetrically distributed on both sides of the magnetic source; two driven wheels rotatably mounted on the frame; a belt mounted on the driving wheels and driven wheels, the belt being used to transport iron; and a plurality of pressure strips for protecting the belt, each pressure strip being equipped with three crab shell bolts, the pressure strips being fixedly connected to the belt through the crab shell bolts.

[0009] In one embodiment of the present invention, the cylinder is rotatably connected to the connecting ring, and the cylinder contains a plurality of the air extraction ports.
[0010] In one embodiment of the present invention, it further includes: an electric telescopic rod fixedly installed on the first connecting plate, the connecting ring being slidably connected to the first connecting plate, the electric telescopic rod being used to drive the connecting ring to move; and a second spring installed on the connecting ring and the first connecting plate.
[0011] In one embodiment of the present invention, it further includes: two straight plates symmetrically installed on both sides of the air extraction port; and a magnetic plate for adsorbing residual iron on the belt, the two ends of the magnetic plate being connected to the two straight plates respectively.
[0012] In one embodiment of the present invention, the straight plate is slidably connected to the cylinder, and a sealing plate is fixedly connected to the two straight plates of the same air extraction port. After the straight plate slides, the air extraction port can be sealed by the sealing plate.
[0013] In one embodiment of the present invention, the device further includes: a second connecting plate fixedly mounted on the frame; a connecting box slidably mounted on the second connecting plate, with a third spring installed between the connecting box and the second connecting plate; a scraper for scraping iron off the magnet plate, the scraper being within the moving range of the magnet plate, the scraper being slidably connected to the connecting box, with a fourth spring installed between the scraper and the connecting box; and a second suction device mounted on the collection box, the second suction device communicating with the connecting box and the collection box, the second suction device being used to draw the iron scraped off the magnet plate into the collection box.
[0014] In one embodiment of the present invention, it further includes: a No. 5 spring connecting the straight plate and the cylinder, one end of the No. 5 spring being fixedly connected to the straight plate and the other end of the straight plate being fixedly connected to the cylinder; and a shaped plate fixedly installed on the connecting ring, the shaped plate being used to drive the straight plate to slide relative to the cylinder, the shaped plate being located within the movement range of the straight plate.
[0015] In one embodiment of the present invention, the invention further includes: two straight grooves and two arc grooves formed on the straight plate; two circular blocks fixedly installed on the magnet plate, the magnet plate being slidably connected to the straight grooves and the arc grooves via the circular blocks; a No. 6 spring installed between the magnet plate and the straight plate; and a protrusion for driving the straight plate to move, the protrusion being fixedly installed on the connecting box and located within the movement range of the straight plate.
[0016] The technical solution of the present invention has the following advantages compared with the prior art:
[0017] 1. The hot slag iron remover of the present invention addresses the issue that the belt material is typically rubber, polyurethane, or polyurethane / rubber composite material. Since the iron blocks in the hot slag are irregularly shaped, the belt wears down during the magnetic attraction process. Furthermore, sharp iron blocks may puncture the belt upon attraction. Replacing the belt is cumbersome, and frequent replacements reduce the efficiency of iron removal. By fixing several pressure strips to the belt with crab shell bolts, the contact area between the belt and the iron blocks is reduced. Simultaneously, the pressure strips have a stronger impact resistance to larger iron blocks than the belt, thus protecting the belt, extending its service life, and improving the aforementioned problems.
[0018] 2. The hot slag iron separator of this invention has a cylinder located above the upper surface of the conveyor belt. During the process of iron blocks in the hot slag being attracted to the conveyor belt by magnetic force, there is a possibility that some smaller particles of other substances in the hot slag may also be carried onto the belt. Some of these small particles may adhere to the belt. During belt operation, these small particles may enter the frame body. After prolonged operation, these substances accumulate on the frame and the belt, affecting the iron removal efficiency and service life of the iron separator. By using a primary exhaust device, suction is generated at the exhaust port connected to the primary exhaust device. This suction draws the small particles of other substances adhering to the belt into a collection box for collection, thus cleaning the belt, improving the aforementioned problems, ensuring the iron removal efficiency of the iron separator, and extending its service life. To extend the lifespan of the iron separator, it is necessary to address the issue that other substances in the hot slag may move upwards along with the iron blocks and onto them, or fall into the iron block collection container along with them. This is achieved through a combination of an adjusting plate assembly and a rotating cylinder. While the belt can be stretched within a certain range, the cylinder rotates, causing the exhaust port to rotate. The suction force on the belt gradually increases and then decreases, allowing the belt to move up and down. The vibration of the belt dislodges other substances from its lower surface, improving the aforementioned problems and increasing the proportion of iron blocks falling into the collection container. Furthermore, the electric telescopic rod extends after the belt shifts, causing the cylinder and the belt sucked up by the exhaust port to move synchronously. This allows for position adjustment of the shifted belt without needing to stop the machine, ensuring the normal operation of the iron separator.
[0019] 3. In the hot slag iron remover described in this invention, some smaller iron blocks remain attached to the conveyor belt as it moves to the discharge end. These smaller iron blocks will then be drawn to the exhaust port along with other materials and collected in the collection box by the first exhaust device, resulting in waste. By setting up a magnetic plate, the iron blocks drawn into the exhaust port are simultaneously attracted to the magnetic plate while the belt is being drawn in, thus improving the above problem. Combined with a scraper, the iron blocks attracted to the magnetic plate can be scraped off, allowing the magnetic plate to work continuously. Furthermore, the inclusion of protrusions and round blocks causes the straight plate to be squeezed when passing over the protrusions, while the round blocks slide within the arc grooves and straight grooves on the straight plate, causing them to rotate and rotate the magnetic plate 180 degrees. This rotates the uncleaned side outwards for cleaning during the next contact with the scraper, ensuring more thorough cleaning of the magnetic plate and guaranteeing its effective adsorption of iron blocks.
[0020] 4. The hot slag iron remover of the present invention, by setting an irregularly shaped plate, allows the straight plate to slide along the surface of the irregularly shaped plate when rotating, which can realize the action of automatically pushing the sealing plate and the magnetic plate on the straight plate to slide. This allows the sealing plate to automatically close the exhaust port in the non-working position, and the magnetic plate to extend when rotating to the vicinity of the scraper. Utilizing the elastic force of the No. 5 spring, there is no need to set up an additional power source to drive the straight plate to move. The structure is simple and saves costs.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.
[0032] Reference Figure 1 As shown, a hot slag iron remover of the present invention includes a frame 1, and further includes: a magnetic source 2 for generating magnetic force, the magnetic source 2 being installed in the middle of the frame 1; two driving wheels 3 rotatably mounted on the frame 1, the two driving wheels 3 being symmetrically distributed on both sides of the magnetic source 2; two driven wheels 4 rotatably mounted on the frame 1; a belt 5 installed on the driving wheels 3 and the driven wheels 4, the belt 5 being used to transport iron; and a plurality of pressure strips 6 for protecting the belt 5, the pressure strips 6 being equipped with three crab shell bolts 61, the pressure strips 6 being fixedly connected to the belt 5 by the crab shell bolts 61.
[0033] Specifically, the pressure bar 6 is located on the outside of the belt 5. The iron separator is a permanent magnet separator, using high-performance neodymium iron boron as the magnetic source 2. The pressure bar 6 is made of stainless steel. Figure 1 In the middle, the lower right of belt 5 is the feed end and the lower left of belt 5 is the discharge end. In order to extract the iron from the hot slag for secondary use, an iron remover is needed at this time.
[0034] Before operation, the frame 1 is installed above the discharge line of the steel slag hot curing production line. A container for collecting iron blocks is placed below the discharge end of the belt 5. During operation, the magnetic source 2 is activated to generate magnetic force, and the two drive wheels 3 are started to rotate clockwise, causing the belt 5 to move from the feed end to the discharge end. When the hot curing slag passes the feed end of the belt 5, the iron in the hot curing slag is moved upward by the magnetic force onto the belt 5, thus removing iron from the hot curing slag. The iron blocks follow the belt 5 from the discharge end to the discharge end. Since the magnetic force generated by the magnetic source 2 has a certain range, the discharge end of the belt 5 is not within this range, causing the iron blocks on the belt 5 at the discharge end to fall into the container, thus collecting the iron blocks. This cycle is repeated to achieve batch iron removal from the hot curing slag.
[0035] Since the material of belt 5 is usually rubber, polyurethane, or polyurethane / rubber composite material, the irregular shapes of the iron blocks in the hot slag cause wear on belt 5 as they are attracted to it by magnetic force. Furthermore, some sharp iron blocks may puncture belt 5 when attracted to it. Replacing belt 5 is cumbersome, and frequent replacements will affect the efficiency of iron removal from the hot slag. By fixing several pressure strips 6 to belt 5 with crab shell bolts 61, the contact area between belt 5 and the iron blocks can be reduced. At the same time, pressure strips 6 have a stronger impact resistance to larger iron blocks than belt 5, thus protecting belt 5, extending its service life, and improving the aforementioned problems.
[0036] like Figure 1-2 As shown, it also includes an adjusting plate 7 for adjusting the slack of the belt 5. The adjusting plate 7 is slidably mounted on the upper surface of the frame 1, and a No. 8 spring is installed between the adjusting plate 7 and the frame 1.
[0037] Specifically, the adjusting plate 7 slides up and down relative to the frame 1. When the hot slag contains large iron blocks, the iron blocks move upward under the influence of magnetic force. When the iron blocks move, they will impact the belt 5. The belt 5 will be indented inward under the impact, which will increase the tension of the belt 5 and may cause the belt 5 to break. When the belt 5 is transporting large iron blocks, it will be pulled outward by the weight of the iron blocks, which will increase the tension of the belt 5 and may also cause the belt 5 to break. When the belt 5 is indented inward or pulled outward, the adjusting plate 7 slides upward and the first spring 8 extends upward, so that the tension of the belt 5 is maintained within a certain range. By setting the adjusting plate 7, the tension of the belt 5 is maintained within a certain range, which improves the above problems and extends the service life of the belt 5.
[0038] like Figure 1-3 As shown, it also includes: two connecting plates 9 fixedly installed on the frame 1, with connecting rings 10 installed on the connecting plates 9; a cylinder 11 installed on the connecting rings 10; a collection box 12 installed on the frame 1, the collection box 12 being used to collect steel slag; a first-order exhaust device 13 installed on the collection box 12, the first-order exhaust device 13 being connected to the cylinder 11 and the collection box 12; and an exhaust port 14 opened on the cylinder 11, after the first-order exhaust device 13 is activated, the steel slag on the belt 5 passes through the exhaust port 14 and enters the collection box 12.
[0039] Specifically, the cylinder 11 is located above the upper surface of the belt 5. During the process of the iron blocks in the hot slag being attracted to the belt 5 by magnetic force, there is a possibility that some smaller particles of other substances in the hot slag may also be carried onto the belt 5. Some small particles may adhere to the belt 5. During the operation of the belt 5, these small particles may enter the interior of the frame 1. After long-term operation, these substances will accumulate on the frame 1 and the belt 5, which will affect the iron removal effect and service life of the iron separator.
[0040] When removing iron from hot slag, the first extraction device 13 is activated, which generates a suction force into the cylinder 11 at the extraction port 14 connected to the first extraction device 13. When the belt 5 moves to the bottom of the cylinder 11, the suction force generated at the extraction port 14 can draw small particles and other substances adhering to the belt 5 into the collection box for collection, thus achieving the cleaning of the slag. By setting the first extraction device 13, the above-mentioned problems are improved, the iron removal effect of the iron separator is guaranteed, and the service life of the iron separator is extended.
[0041] like Figure 2-3 As shown, the cylinder 11 is rotatably connected to the connecting ring 10, and the cylinder 11 contains a plurality of the air extraction ports 14.
[0042] Specifically, since other substances in the hot slag may move upwards along with the iron block and onto it, and may also fall into the container for collecting the iron block along with it; during operation, the cylinder 11 rotates, causing the exhaust port 14 to rotate, so that the exhaust port 14 sucks up other substances on the belt 5 while rotating. When one of the exhaust ports 14 rotates downwards, the suction force inside the exhaust port 14 gradually increases until the belt 5 can move upwards. As the exhaust port 14 continues to rotate upwards, the suction force on the belt 5 gradually decreases until the belt 5 moves downwards to its initial state. The up-and-down movement of the belt 5 can cause the belt 5 to vibrate, causing other substances on the lower surface of the belt 5 to be shaken off. By setting multiple exhaust ports 14, it is ensured that the exhaust ports 14 can continuously clean other substances on the belt 5 and shake off some other substances below the belt 5, thus improving the above-mentioned problems and increasing the proportion of iron blocks falling into the container for collecting iron blocks.
[0043] like Figure 2 As shown, it also includes: an electric telescopic rod 15 fixedly installed on the first connecting plate 9, the connecting ring 10 being slidably connected to the first connecting plate 9, the electric telescopic rod 15 being used to drive the connecting ring 10 to move; and a second spring 16 installed on the connecting ring 10 and the first connecting plate 9.
[0044] Specifically, in Figure 2In the middle, with the two sides where the No. 1 connecting plates 9 are located as the left and right sides, the electric telescopic rod 15 can extend left and right relative to the No. 1 connecting plate 9, and the connecting ring 10 can slide horizontally left and right relative to the No. 1 connecting block. During long-term operation of the iron separator, the belt 5 has the problem of displacement. In the initial state, such as Figure 2 As shown, when belt 5 is observed to shift to the left, as belt 5 moves upward under the suction force of the suction port 14, the electric telescopic rod 15 on the left side of belt 5 is extended to the right, causing the connecting ring 10 to move synchronously to the right. This causes the cylinder 11 and the suction port 14 to move, which in turn causes belt 5 to move synchronously to the right, allowing belt 5 to return to normal. At this time, the second spring 16 on the left side extends, and the second spring 16 on the right side retracts. When belt 5 moves downward due to the reduced suction force of the suction port 14, the electric telescopic rod 15 is retracted to the left, and the connecting ring 10 is retracted by the second spring. The elastic force of the 16 spring moves the belt 5 to the left and returns it to its initial position. The movement of the connecting ring 10 drives the cylinder 11 and the air extraction port 14 to move to the left synchronously. If the belt 5 does not return to its original position after one movement, the electric telescopic rod 15 can be controlled to extend again when the belt 5 moves upward under the suction force in the air extraction port 14 until the belt 5 returns to normal. If the belt 5 moves to the right, the electric telescopic rod 15 on the right side is controlled to extend to the left. By setting the electric telescopic rod 15, the displaced belt 5 can be restored to normal without stopping the machine for adjustment, thus ensuring the working efficiency of the iron separator.
[0045] like Figure 2-3 As shown, it also includes: two straight plates 17 symmetrically installed on both sides of the air extraction port 14; and a magnetic plate 18 for adsorbing the remaining iron on the belt 5, with the two ends of the magnetic plate 18 respectively connected to the two straight plates 17.
[0046] Specifically, some smaller iron blocks remain attached to the belt 5 as it moves to the discharge end of the belt 5. They will then move with the belt 5 to the exhaust port 14 and be drawn into the collection box by the first exhaust device 13 along with other materials. This results in the waste of these iron blocks. By setting up a magnetic plate 18, these iron blocks can be attracted to the magnetic plate 18 when they enter the exhaust port 14 along with other materials, thus improving the above problem.
[0047] like Figure 3 As shown, the straight plate 17 is slidably connected to the cylinder 11, and sealing plates 19 are fixedly connected to the two straight plates 17 of the same air extraction port 14. After the straight plate 17 slides, the air extraction port 14 can be sealed by the sealing plates 19.
[0048] Specifically, the straight plate 17 can move relative to the axis of the cylinder 11. Figure 3In this context, the rotation range between the two downward-facing suction ports 14 is defined as the working position of the suction port 14. Initially, the sealing plate 19 prevents the suction port 14 from connecting with the cylinder 11, meaning the suction port 14 is closed. When one of the suction ports 14 on the cylinder 11 rotates to its working position, the straight plate 17 on that working position slides closer to the axis of the cylinder 11, causing the sealing plate 19 on that suction port 14 to move synchronously towards the axis. At this point, the suction port 14 connects with the cylinder 11, thus opening the suction port 14 and connecting it with the first suction device 13. Suction is generated at the suction port 14, which can draw small particles adhering to the belt 5 into the suction port 14. The remaining suction ports 14 remain closed. When the cylinder 11 is in the closed state, it continues to rotate. When the exhaust port 14 rotates to the working position, it moves away from the axis of the cylinder 11. The straight plate 17 drives the sealing plate 19 to move synchronously, so that the sealing plate 19 seals the exhaust port 14, thus closing the exhaust port 14. At the same time, when the exhaust port 14 is closed, the next exhaust port 14 rotates to the working position, and the sliding straight plate 17 can be used to open the exhaust port 14. By setting the sealing plate 19 to close and open the exhaust port 14, only the exhaust port 14 located at the working position is in the open state. Compared with all the exhaust ports 14 being in the open state, under the same suction force at the exhaust port 14, the suction force generated by the first exhaust device 13 is smaller, the power of the first exhaust device 13 is smaller, and the power consumption of the first exhaust device 13 is smaller, thus saving electricity.
[0049] like Figure 1-3 As shown in Figure 5, it also includes: a second connecting plate 20 fixedly installed on the frame 1; a connecting box 21 slidably installed on the second connecting plate 20, with a third spring 22 installed between the connecting box 21 and the second connecting plate 20; a scraper 23 for scraping iron off the magnet plate 18, the scraper 23 being located within the moving range of the magnet plate 18, the scraper 23 being slidably connected to the connecting box 21, with a fourth spring 24 installed between the scraper 23 and the connecting box 21; and a second suction device 25 installed on the collection box 12, the second suction device 25 being connected to the connecting box 21 and the collection box 12, the second suction device 25 being used to draw the iron scraped off the magnet plate 18 into the collection box 12.
[0050] Specifically, the collection box 12 is divided into two parts. The part connected to the first suction device 13 collects other substances in the hot slag, and the part connected to the second suction device 25 collects iron blocks. A lid is rotatably installed on top of the connecting box 21. During the rotation of the cylinder 11, the lid is automatically lifted, and after the cylinder 11 passes, the lid returns to its original state under gravity. The lid is designed to reduce the airflow area between the connecting box 21 and the outside air, ensuring that the suction force generated by the second suction device 25 can draw the iron blocks into the collection box 12. Figure 5 In the middle, the cylinder 11 rotates counterclockwise, the connecting box 21 slides left and right relative to the second connecting plate 20, and the scraper 23 slides left and right relative to the connecting box 21. The sliding of the scraper 23 ensures that when the magnet plate 18 rotates to contact the scraper 23, the scraper 23 can always stick to the surface of the magnet plate 18. Since the volume of iron blocks attracted by the magnet plate 18 is limited, it will lose its function when the magnet plate 18 is full of iron blocks. At this time, the magnet plate 18 inside the cylinder 11 needs to be removed.
[0051] Before starting work, the second suction device 25 is activated for suction. As the exhaust port rotates counter-clockwise out of the working position, the cylinder 11 rotates counter-clockwise and contacts the connecting box 21, pushing the connecting box 21 to the right. At this time, the third spring 22 contracts. When the cylinder 11 rotates to the point where it no longer contacts the connecting box 21, the connecting box 21 returns to its initial state under the elastic force of the third spring 22. At this point, the exhaust port is no longer in the working position. The straight plate 17 slides outward in a direction away from the axis of the cylinder 11, causing the magnetic plate 18 to move outward synchronously until the magnetic plate 18 moves out of the exhaust port. Figure 3 As shown by the exhaust vent in the lower right corner, the cylinder 11 continues to rotate counterclockwise, causing the magnetic plate 18 to rotate. During the rotation of the magnetic plate 18, it comes into contact with the scraper 23. The scraper 23 can scrape the iron blocks on the magnetic plate 18 into the connecting box 21, and then the iron blocks are drawn into the collection box 12 for storage by the suction of the second suction device 25. By setting the scraper 23, the iron blocks on the magnetic plate 18 can be scraped off, which improves the above-mentioned problem and allows the magnetic plate 18 to work continuously, making it highly practical.
[0052] like Figure 3-4 As shown in Figure 6, it also includes: a No. 5 spring 26 connecting the straight plate 17 and the cylinder 11, one end of the No. 5 spring 26 being fixedly connected to the straight plate 17, and the other end of the straight plate 17 being fixedly connected to the cylinder 11; and a shaped plate 27 fixedly installed on the connecting ring 10, the shaped plate 27 being used to drive the straight plate 17 to slide relative to the cylinder 11, the shaped plate 27 being located within the movement range of the straight plate 17.
[0053] Specifically, in the initial state, spring 26 is in a contracted state. During operation, cylinder 11 rotates counterclockwise, causing straight plate 17 to rotate counterclockwise. During rotation, straight plate 17 slides along the surface of shaped plate 27. When straight plate 17 reaches the working position, it slides towards the axis of cylinder 11 under the force of spring 26, causing sealing plate 19 to slide synchronously. Figure 3 As shown in the lower left corner of the image, the straight plate 17 is currently open, allowing for the suction of material adhering to the belt 5. As the straight plate 17 continues to rotate away from the workstation and enters the connecting box 21, it slides along the surface of the irregular plate 27, causing it to slide away from the axis of the cylinder 11. This movement causes the magnetic plate 18 and the sealing plate 19 on the cardboard to move synchronously, closing the suction port. Simultaneously, the magnetic plate 18 slides out of the suction port, and the fifth spring 26 contracts, closing the connecting box. The scraper 23 inside 21 can clean the magnetic plate 18. The cylinder 11 continues to rotate. When the exhaust port rotates out of the connecting box 21, the straight plate 17 rotates and slides along the surface of the irregular plate 27. Under the action of the elastic force of the No. 5 spring 26, the straight plate 17 slides towards the axis of the cylinder 11, driving the magnetic plate 18 to slide synchronously until the magnetic plate 18 enters the exhaust port. By setting the irregular plate 27, the elastic force of the No. 5 spring 26 can make the sealing plate 19 and the magnetic plate 18 move by themselves during rotation, without the need for an additional power source to drive them.
[0054] like Figure 5-8 As shown, it also includes: two straight grooves 28 and two arc grooves 29 formed on the straight plate 17; two round blocks 30 fixedly installed on the magnet plate 18, the magnet plate 18 being slidably connected to the straight grooves 28 and arc grooves 29 through the round blocks 30; a No. 6 spring 31 installed between the magnet plate 18 and the straight plate 17; and a protrusion 32 for driving the straight plate 17 to move, the protrusion 32 being fixedly installed on the connecting box 21 and located within the movement range of the straight plate 17.
[0055] Specifically, the two ends of the straight groove 28 are connected to one end of each of the two circular arc grooves 29. The connection point between the straight groove 28 and the circular arc groove 29 near the end of the magnet plate 18 is the first connection point. The depth of the circular arc groove 29 at the first connection point is greater than the depth of the straight groove 28. The connection point between the straight groove 28 and the circular arc groove 29 near the end of the magnet plate 18 is the second connection point. The depth of the straight groove 28 at the second connection point is greater than the depth of the circular arc groove 29. In the initial state, the circular block 30 is connected to the first connection point.
[0056] When the straight plate 17 rotates to contact the protrusion 32, since the protrusion 32 remains stationary, the two straight plates 17 move horizontally in a straight line towards each other due to the pressure from the protrusion 32. That is, the straight plates 17 move towards the magnet plate 18, causing the straight groove 28 and the arc groove 29 to move synchronously. Since the depth of the arc groove 29 at the first connection point is greater than the depth of the straight groove 28, the round block 30 slides within the arc groove 29 to the second connection point, causing the round block 30 to rotate 180 degrees. The rotation of the round block 30 drives the magnet plate 18 to rotate 180 degrees. At this time, the sixth spring 31 contracts. When the straight plate 17 rotates to the point where it no longer contacts the protrusion 32... Under the elastic force of spring 31, the straight plate 17 moves away from the magnetic plate 18 until it returns to its initial state, causing the straight groove 28 and the arc groove 29 to move synchronously. Since the depth of the straight groove 28 at the second connection is greater than the depth of the arc groove 29, the round block 30 slides in the straight groove 28, while the magnetic plate 18 remains stationary. This allows the magnetic plate 18 to rotate once after the scraper 23 removes the iron block, rotating the side of the iron block that has not been removed to the outside so that it can be cleaned when the straight plate 17 rotates to the scraper 23 next time. This makes the cleaning of the magnetic plate 18 more comprehensive and ensures the adsorption effect of the magnetic plate 18 on the iron block.
[0057] Work steps:
[0058] Step 1: Before operation, install frame 1 above the discharge line of the steel slag hot curing production line. Place a container for collecting iron blocks below the discharge end of belt 5. Activate suction device 13 and suction device 25, causing suction force to be generated at the suction port 14 connected to suction device 13 into the cylinder 11, and suction force to be generated in the connecting box 21 connected to suction device 25. During operation, activate magnetic source 2 to generate magnetic force, and start the two drive wheels 3 to rotate clockwise, causing belt 5 to move along the feed end. Moving towards the discharge end, when the hot slag passes the feed end of the belt 5, the iron in the hot slag is moved upward onto the belt 5 by the magnetic force, thus realizing the iron removal work of the hot slag. The iron blocks follow the belt 5 from the discharge end to the discharge end. Since the magnetic force generated by the magnetic source 2 has a certain range, the discharge end of the belt 5 is not within this range, causing the iron blocks on the belt 5 at the discharge end to fall into the container, thus realizing the collection of iron blocks. This cycle is repeated to realize the batch iron removal work of the hot slag.
[0059] Step 2: During operation, the cylinder 11 rotates counterclockwise, causing the straight plate 17 to rotate counterclockwise. During this rotation, the straight plate 17 slides along the surface of the shaped plate 27. When the straight plate 17 reaches the working position, it slides towards the axis of the cylinder 11 under the force of the fifth spring 26, causing the sealing plate 19 to slide synchronously. Figure 3 As shown in the lower left corner of the straight plate 17, this is how the air vent is opened;
[0060] Step 3: At this time, the suction force generated in the exhaust port 14 can draw the material adhering to the belt 5 that has moved from the discharge end to the vicinity of the exhaust port 14 into the exhaust port 14 and into the collection box for storage. At the same time, the iron blocks on the belt 5 that have not fallen into the container are attracted by the magnetic plate 18 in the exhaust port and are adsorbed on the magnetic plate 18, thus realizing the action of cleaning the material adhering to the belt 5.
[0061] Step 4: As the air intake port 14 rotates downward, the suction force inside the air intake port 14 gradually increases until the belt 5 can move upward. As the air intake port 14 continues to rotate upward, the suction force on the belt 5 gradually decreases until the belt 5 moves downward back to the initial state. The up-and-down movement of the belt 5 can cause the belt 5 to vibrate, causing other materials on the lower surface of the belt 5 to be shaken off, thus achieving the action of shaking off other materials on the lower surface of the belt 5.
[0062] Step 5: As the cylinder 11 continues to rotate counterclockwise, the straight plate 17 continues to rotate until it moves away from the working position and enters the connecting box 21. While rotating, the straight plate 17 slides along the surface of the irregular plate 27, causing the straight plate 17 to slide away from the axis of the cylinder 11. This causes the magnetic plate 18 and the sealing plate 19 on the cardboard to move synchronously, so that the sealing plate 19 closes the exhaust port, and the magnetic plate 18 slides out of the exhaust port. This achieves the action of closing the exhaust port and sliding out the magnetic plate 18. At the same time, the next exhaust port rotates to the working position and cleans the material on the belt 5.
[0063] Step 6: The cylinder 11 continues to rotate counterclockwise, causing the magnetic plate 18 to rotate. During the rotation of the magnetic plate 18, it comes into contact with the scraper 23. The scraper 23 can scrape the iron block on the magnetic plate 18 into the connecting box 21, and then use the suction of the second suction device 25 to draw the iron block into the collection box 12 for storage.
[0064] Step 7: When the straight plate 17 rotates to contact the protrusion 32, since the protrusion 32 remains stationary, the two straight plates 17 move horizontally in a straight line towards each other due to the pressure from the protrusion 32. That is, the straight plates 17 move towards the magnet plate 18, causing the straight groove 28 and the arc groove 29 to move synchronously. Since the depth of the arc groove 29 at the first connection point is greater than the depth of the straight groove 28, the round block 30 slides within the arc groove 29 to the second connection point, causing the round block 30 to rotate 180 degrees. The rotation of the round block 30 drives the magnet plate 18 to rotate 180 degrees. At this time, the sixth spring 31 contracts. When the straight plate 17 rotates to the point where it no longer contacts the protrusion 32, the straight plate 17 moves away from the magnet plate 18 under the action of the elastic force of the sixth spring 31 until it returns to its initial state. This causes the straight groove 28 and the arc groove 29 to move synchronously. Since the depth of the straight groove 28 at the second connection is greater than the depth of the arc groove 29, the round block 30 slides in the straight groove 28 at this time, while the magnet plate 18 remains stationary. This allows the magnet plate 18 to rotate once after the scraper 23 removes the iron block, rotating the side of the iron block that has not been removed to the outside so that it can be cleaned when the straight plate 17 rotates to the scraper 23 next time.
