Description

Technical Field

[0001] This invention relates to the field of yellow phosphorus production equipment technology, and in particular to a structure placed in the furnace cover that serves both as a gas guide and a dust remover. Background Technology

[0002] The yellow phosphorus electric furnace is a closed-loop submerged arc furnace and is the core thermal equipment for the electric furnace method of producing yellow phosphorus. Its phosphorus recovery principle is as follows: the phosphorus furnace gas is sent to a condenser tower through a gas pipe. Under the forced cooling effect of water spraying inside the tower, the phosphorus furnace gas changes from a gaseous phase to a liquid phase, ultimately yielding the yellow phosphorus product.

[0003] Currently, the gas guide pipes of mainstream yellow phosphorus electric furnaces are all installed sideways on the furnace wall. Due to the limitation of installation space, the pipe diameter cannot be increased. Phosphorus-containing dust that settles in the gas guide pipe easily adheres to the pipe wall and accumulates continuously, forming a large area of ​​material buildup. When material buildup occurs in the gas guide pipe, the pipe diameter is reduced, thereby squeezing the flow space of phosphorus furnace gas. This leads to an increase in the flow rate and temperature of phosphorus furnace gas, and the phosphorus-containing dust entrained in the phosphorus furnace gas will increase accordingly. After entering the condensation tower, the phosphorus-containing dust mixes with liquid yellow phosphorus to form mud phosphorus, which also causes the mud phosphorus content in the circulating water to exceed the standard. This not only increases the difficulty of subsequent treatment but also easily causes environmental pollution problems. Therefore, this invention provides a structure that is placed in the middle of the furnace cover and has both gas guiding and dust removal functions to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a structure that is placed in the furnace cover and has the functions of both guiding gas and removing dust. By setting up a gas guiding component, it can not only guide the phosphorus furnace gas entering the first gas guiding pipe, so that the phosphorus furnace gas impacts the inner wall of the first gas guiding pipe and reduces the flow rate of the phosphorus furnace gas, and realize the separation of solid particles and gas by using the principle of gravity settling, but also scrape off the phosphorus-containing dust attached to the inner wall of the first gas guiding pipe, and guide the scraped phosphorus-containing dust and the settled phosphorus-containing dust into the furnace space of the electric furnace for re-evaporation, so as to avoid phosphorus-containing dust adhering to the furnace wall and forming material deposits, thereby reducing the production of mud phosphorus, increasing the phosphorus yield and reducing production consumption. It solves the problems that phosphorus-containing dust easily settles on the inner wall of the gas guiding pipe, forming material deposits and affecting the operation of the electric furnace.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a gas guiding component, not only can the phosphorus furnace gas entering the first gas guiding pipe be guided so that it impacts the inner wall of the first gas guiding pipe, reducing the flow rate of the phosphorus furnace gas, and using the principle of gravity settling to separate solid particles from gas, but it can also scrape off the phosphorus-containing dust attached to the inner wall of the first gas guiding pipe, and guide the scraped-off phosphorus-containing dust and the settled phosphorus-containing dust into the furnace space of the electric furnace for re-evaporation, avoiding the formation of phosphorus-containing dust adhering to the furnace wall and thus reducing the production of mud phosphorus, increasing the phosphorus yield and reducing production consumption.

[0016] By setting a first fixed plate, a limiting cylinder, a first fixed column, and a fan plate in the gas guiding assembly, not only can the phosphorus furnace gas entering the first gas guiding pipe be guided and the flow rate of the phosphorus furnace gas be reduced, but the separation of solid particles and gas can also be achieved by using the principle of gravity settling. The separated phosphorus-containing dust will be guided by the first inclined surface, and the settled phosphorus-containing dust will fall back into the furnace space of the electric furnace through the inner wall of the fixed cylinder, avoiding the formation of material hanging at the connection of the first gas guiding pipe.

[0017] By setting a third fixed column, a shovel plate, an anti-detachment ring, and a rotating plate inside the gas guiding assembly, phosphorus-containing dust adhering to the inner wall of the first gas guiding pipe can be scraped off during the rotation of the rotating plate, thus preventing the accumulation of large amounts of dust. The accumulation of phosphorus-containing dust will reduce the diameter of the first gas guiding pipe, compress the gas outlet section of the phosphorus furnace gas and the gas phase buffer area, resulting in the inability to reduce the furnace gas flow rate, which in turn affects the use of gravity settling to complete the gas-solid two-phase separation.

[0018] By setting a first connecting plate, a second connecting plate, a second connecting column, a push button, a fourth connecting plate, a fifth connecting plate, and an abutment block on the air guide assembly, the first pulley can be released by pushing the push button, and the first pulley can be moved by holding the second connecting column. As the first pulley moves, the second pulley will be moved synchronously, and the rotating plate will be lifted by the abutment block, providing conditions for the rotation of the first fixed column.

[0019] By setting a third connecting plate, a rotating column, a third pulley, a belt, and a handle on the air guide assembly, the first pulley can be rotated by holding the handle, thereby driving the third pulley to rotate synchronously, providing conditions for the subsequent scraping of phosphorus-containing dust on the inner wall of the first air guide tube by the shovel plate.

Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0027] like Figures 1 to 11 As shown, an embodiment of the present invention provides a structure placed in the furnace cover that serves both as a gas guide and a dust collector. The structure includes an electric furnace 1, which is a closed submerged arc furnace with an internal furnace chamber for producing yellow phosphorus using the electric furnace method. A gas guide assembly is installed on the top of the electric furnace 1, and a first gas guide pipe 2 is fixedly connected to the top of the gas guide assembly. The first gas guide pipe 2 is a hollow metal cylinder used to exhaust phosphorus furnace gas from the electric furnace 1. A second gas guide pipe 3 is fixedly connected to the outer wall of the first gas guide pipe 2 near its top end. The second gas guide pipe 3 is a Z-shaped hollow metal cylinder with inclined ends, used to exhaust phosphorus furnace gas from the first gas guide pipe 2. A cooling spray water device 6 is installed on the outer wall of the second gas guide pipe 3 near one end of the first gas guide pipe 2. The cooling spray water device 6 includes... The system includes a spray pipe, nozzles, and a water supply assembly. Multiple nozzles are evenly arranged along the inner wall of the inclined section of the second gas guide pipe 3, which can spray cooling water into the pipe, thus extending the cooling time of the phosphorus furnace gas, improving condensation efficiency, and thereby increasing phosphorus yield. The other end of the first gas guide pipe 2 is fixedly connected to a condensation tower 4, and the bottom end of the condensation tower 4 is fixedly connected to a phosphorus receiving tank 5. The cooling spray water device 6, the condensation tower 4, and the phosphorus receiving tank 5 are all prior art and will not be described in detail. The gas guide assembly is used to reduce the dust carried by the phosphorus furnace gas. The gas guide assembly includes a fixed cylinder 7 fixedly connected to the outer wall of the top of the electric furnace 1. The fixed cylinder 7 is a hollow metal cylinder, and the bottom end of the fixed cylinder 7 is fixedly connected to the outer wall of the top of the electric furnace 1, located directly above the furnace chamber space inside the electric furnace 1 (e.g., Figure 1 To reduce the constraint of installation space on the pipe diameter, the top of the fixed cylinder 7 is fixedly connected to the bottom of the first gas guide pipe 2, so that the phosphorus furnace gas in the electric furnace 1 can enter the first gas guide pipe 2 through the inner wall of the fixed cylinder 7.

[0028] This application, by setting up a gas guiding component, can not only guide the phosphorus furnace gas entering the first gas guiding pipe 2, causing the phosphorus furnace gas to impact the inner wall of the first gas guiding pipe 2 and reduce the flow rate of the phosphorus furnace gas, and realize the separation of solid particles and gas by utilizing the principle of gravity settling, but also scrape off the phosphorus-containing dust attached to the inner wall of the first gas guiding pipe 2, and guide the scraped-off phosphorus-containing dust and the settled phosphorus-containing dust into the furnace space of the electric furnace 1 for re-evaporation, avoiding the formation of phosphorus-containing dust adhering to the furnace wall and thus reducing the production of mud phosphorus, increasing the phosphorus yield and reducing production consumption.

[0029] In this embodiment, as Figures 2 to 6 As shown, a first inclined surface 8 is provided on the inner wall of the fixed cylinder 7 near the top. The two ends of the first fixed plate 19 are fixedly connected to the outer wall of the first inclined surface 8. A limiting cylinder 20 is fixedly connected to the outer wall of the middle part of the first fixed plate 19. A third limiting groove 21 is symmetrically opened on the outer wall of the limiting cylinder 20 near the top. A second fixed plate 22 is fixedly connected to the inner wall of the fixed cylinder 7 near the middle. One end of the spring 23 abuts against the bottom outer wall of the second fixed plate 22. A fixing protrusion 24 is fixedly connected to the other end of the spring 23. A first fixing post 25 is fixedly connected to the top of the fixing protrusion 24. Several fan plates 26 arranged in a circular array are fixedly connected to the outer wall of the first fixing post 25 near the bottom. A second fixing post 27 is fixedly connected to the top of the first fixing post 25.

[0030] Specifically, the first fixing plate 19 is a square metal plate, and both ends of the first fixing plate 19 are fixedly connected to the outer wall of the first inclined surface 8. The limiting cylinder 20 is a hollow metal cylinder, and the limiting cylinder 20 is fixedly connected to the middle outer wall of the first fixing plate 19. The third limiting groove 21 is a square groove, and there are two third limiting grooves 21. The two third limiting grooves 21 are symmetrical about the central axis of the limiting cylinder 20, and the inner wall of the third limiting groove 21 near the top is provided with rounded corners, which has a guiding effect. The two ends of the second fixing plate 22 are fixedly connected to the inner wall of the fixing cylinder 7 near the middle. The second fixing plate 22 is a square metal plate with a circular groove in the middle. One end of the spring 23 abuts against the bottom outer wall of the second fixing plate 22, and the other end of the spring 23 is fixedly connected to a fixing protrusion 24. The spring 23 is a prior art disclosure, so it will not be described in detail. The spring 23 is a convex metal plate. The spring 23 is a cylindrical metal cylinder. Since the outer contour of the spring 23 matches the inner contour of the second fixed plate 22, the spring 23 can slide on the inner wall of the second fixed plate 22. The first fixed post 25 is fixedly connected to the top of the fixed protrusion 24. The first fixed post 25 is a cylindrical metal cylinder, and the outer contour of the first fixed post 25 matches the inner contour of the limiting cylinder 20. Therefore, the first fixed post 25 can slide on the inner wall of the limiting cylinder 20. There are four fan plates 26 in total. The four fan plates 26 are fixedly connected to the outer wall of the first fixed post 25 near the bottom end, and the four fan plates 26 are arranged in a circumferential array. The second fixed post 27 is fixedly connected to the top of the first fixed post 25. The second fixed post 27 is a cylindrical metal cylinder, and the outer contour of the second fixed post 27 matches the inner contour of the third limiting groove 21. Therefore, the second fixed post 27 can slide on the inner wall of the third limiting groove 21.

[0031] During operation, the phosphorus gas generated inside the electric furnace 1 enters the first gas guide pipe 2 through the inner wall of the fixed cylinder 7. Guided by the fan plate 26, the phosphorus gas impacts the inner wall of the first gas guide pipe 2, thus reducing its flow rate to some extent. During this process, the second fixed column 27 is positioned within the third limiting groove 21, limiting the first fixed column 25 and preventing it from rotating on the inner wall of the limiting cylinder 20. The fan plate 26 also does not rotate with the first fixed column 25. When the second fixed... The column 27 slides along the inner wall of the third limiting groove 21 toward the top of the limiting cylinder 20. At this time, the first fixed column 25 will slide synchronously along the inner wall of the limiting cylinder 20 under the action of the second fixed column 27. The fan plate 26 and the fixed protrusion 24 move synchronously with the first fixed column 25. The spring 23 will be stressed and deform along its bending direction until the second fixed column 27 slides out from the inner wall of the third limiting groove 21. In this way, the second fixed column 27 no longer limits the first fixed column 25. When the second fixed column 27 is stressed... When the first fixed post 25 rotates around the central axis of the fixed cylinder 7, it will rotate along the inner wall of the limiting cylinder 20 under the drive of the second fixed post 27, and drive the fan plate 26 to rotate synchronously. When the second fixed post 27 is no longer under force, the spring 23 is no longer under force and returns to its original deformation along its bending direction. At this time, the fixed protrusion 24 will move towards the bottom of the fixed cylinder 7 under the drive of the spring 23. The first fixed post 25 and the fan plate 26 will move synchronously under the drive of the fixed protrusion 24. At this time, the second fixed post 25 will rotate around the central axis of the fixed cylinder 7. Driven by the first fixed column 25, 7 slides into the third limiting groove 21 near the top rounded corner. The above structure not only guides the phosphorus furnace gas entering the first gas guide pipe 2 and reduces the flow rate of the phosphorus furnace gas, but also uses the principle of gravity settling to separate solid particles from gas. The separated phosphorus-containing dust will be guided by the first inclined surface 8, and the settled phosphorus-containing dust will fall back into the furnace space of the electric furnace 1 through the inner wall of the fixed cylinder 7, avoiding the formation of material hanging at the connection of the first gas guide pipe 2.

[0032] In this embodiment, as Figures 3 to 6 As shown, the two ends of the second fixing column 27 are symmetrically fixedly connected to the third fixing column 28. The outer wall of the third fixing column 28 near the middle is fixedly connected to the shovel plate 29. The top of the third fixing column 28 is slidably connected to the anti-detachment ring 35. The bottom outer wall of the anti-detachment ring 35 is provided with the third sliding groove 36. The outer wall of the first inclined surface 8 near the middle is provided with the first rotating groove 9. The bottom end of the third fixing column 28 is fixedly connected to the rotating plate 30. The outer wall of the rotating plate 30 near the bottom is provided with the third inclined surface 58. The inner wall of the first rotating groove 9 near the middle is provided with a plurality of second connecting grooves 34 arranged in a circular array.

[0033] Specifically, two third fixing posts 28 are symmetrically fixedly connected to the two ends of the second fixing post 27. The third fixing post 28 is a metal cylinder. The shovel plate 29 is fixedly connected to the outer wall of the third fixing post 28 near the middle. The shovel plate 29 is an arc-shaped metal plate, and the outer wall of the shovel plate 29 away from the third fixing post 28 will abut against the inner wall of the first air guide tube 2. During this process, the shovel plate 29 will be subjected to force and deform along its bending direction. The top ends of the two third fixing posts 28 are slidably connected to the same anti-detachment ring. 35. The anti-detachment ring 35 is a trapezoidal annular column, and the outer contour of the anti-detachment ring 35 is adapted to the inner contour of the first air guide tube 2. Therefore, the anti-detachment ring 35 can slide on the inner wall of the first air guide tube 2. The third sliding groove 36 is formed on the bottom outer wall of the anti-detachment ring 35. The third sliding groove 36 is an annular groove with a convex cross-section, and the inner contour of the third sliding groove 36 is adapted to the top outer contour of the third fixing post 28. Therefore, the third fixing post 28 can slide on the inner wall of the third sliding groove 36. The first rotating groove 9 is formed on the outer wall of the first inclined surface 8 near the middle. The first rotating groove 9 is an annular groove with a convex cross-section, and the inner wall contour of the first rotating groove 9 matches the outer wall contour of the third fixed post 28. Therefore, the third fixed post 28 can slide on the inner wall of the first rotating groove 9. The bottom ends of the two third fixed posts 28 are fixedly connected to the same rotating plate 30. The rotating plate 30 is a hollow metal circular plate, and several toothed grooves are formed on the outer wall of the rotating plate 30 near the top in a circumferential array. The outer contour of the plate 30 is adapted to the inner contour of the first rotating groove 9, so the rotating plate 30 can slide on the inner wall of the first rotating groove 9. The third inclined surface 58 is set on the outer wall of the rotating plate 30 near the bottom. The second connecting groove 34 is opened on the inner wall of the first rotating groove 9 near the middle. The second connecting groove 34 is a fan-shaped groove. There are two second connecting grooves 34. The two second connecting grooves 34 are arranged in a circumferential array, which can guide the phosphorus-containing dust falling into the first rotating groove 9 into the fixed cylinder 7 and then into the furnace space.

[0034] When the rotating plate 30 is subjected to force and slides along the inner wall of the first rotating groove 9 toward the top of the fixed cylinder 7, the third fixed column 28 will slide synchronously along the inner wall of the first rotating groove 9 under the drive of the rotating plate 30. At this time, the shovel plate 29 and the anti-detachment ring 35 will slide synchronously with the third fixed column 28. During this process, the third fixed column 28 will drive the second fixed column 27 to slide along the inner wall of the third limiting groove 21 toward the top of the fixed cylinder 7, releasing the limitation on the first fixed column 25. When the rotating plate 30 rotates after being subjected to force, the rotating plate 30 will drive the two third fixed columns 28 to rotate synchronously along the inner wall of the first rotating groove 9. At this time, the two third fixed columns The top of 28 will slide along the inner wall of the third sliding groove 36, and the shovel plate 29 will also rotate synchronously with the third fixed column 28. The outer wall of the shovel plate 29 away from the third fixed column 28 will abut against the inner wall of the first gas guide pipe 2, and scrape off the phosphorus-containing dust attached to the inner wall of the first gas guide pipe 2 during the rotation. The above structure can scrape off the phosphorus-containing dust attached to the inner wall of the first gas guide pipe 2 during the rotation of the rotating plate 30, avoiding the accumulation of a large amount of dust. The accumulation of phosphorus-containing dust will reduce the diameter of the first gas guide pipe 2, compress the gas outlet section of the phosphorus furnace gas and the gas phase buffer area, resulting in the inability to reduce the furnace gas flow rate, which in turn affects the use of gravity settling to complete the gas-solid two-phase separation.

[0035] In this embodiment, as Figures 6 to 10As shown, a first connecting plate 10 and a second connecting plate 15 are fixedly connected to the outer wall of the fixed cylinder 7. Both the first connecting plate 10 and the second connecting plate 15 are square metal plates. There are two second connecting plates 15, which are symmetrical about the central axis of the fixed cylinder 7. A second sliding groove 17 is formed on the outer wall of the fixed cylinder 7 near the second connecting plate 15. The second sliding groove 17 is a square groove, and there are two second sliding grooves 17. The two second sliding grooves 17 are symmetrical about the central axis of the fixed cylinder 7 and are connected to the first rotating groove 9. A second limiting groove 12 is formed on the outer wall of the first connecting plate 10 at the end away from the fixed cylinder 7. The first connecting plate 10 is close to the second limiting groove 12. A first limiting groove 11 is formed on the outer wall of the first connecting plate 10. Both the second limiting groove 12 and the first limiting groove 11 are circular grooves. A U-shaped plate 38 is slidably connected to the outer wall of the first connecting plate 10. The U-shaped plate 38 is a U-shaped metal plate, and the inner contour of the U-shaped plate 38 matches the outer contour of the first connecting plate 10. Therefore, the U-shaped plate 38 can slide on the outer wall of the first connecting plate 10. A first connecting post 39 is fixedly connected to the top of the U-shaped plate 38. The first connecting post 39 is an I-shaped hollow metal cylinder. A second connecting post 40 is fixedly connected to the top of the first connecting post 39. The second connecting post 40 is a metal cylinder. A fourth sliding groove 41 is formed on the outer wall of the top of the second connecting post 40. The fourth sliding groove 41 is a circular groove. Furthermore, the fourth sliding groove 41 is connected to the inner wall of the first connecting post 39. A fifth sliding groove 42 is formed on the outer wall of the second connecting post 40 near its top. The fifth sliding groove 42 is a square-shaped groove and is connected to the fourth sliding groove 41. One end of a tension spring 43 is fixedly connected to the bottom inner wall of the fourth sliding groove 41, and the other end of the tension spring 43 is fixedly connected to a first sliding post 44. The first sliding post 44 is a metal cylinder, and its outer wall profile matches the inner wall profile of the fourth sliding groove 41, allowing it to slide on the inner wall of the fourth sliding groove 41. One end of a second sliding post 46 is fixedly connected to the bottom outer wall of the first sliding post 44, and the other end of the second sliding post 46 is... At the open end, the second sliding post 46 is a metal cylinder, and its outer wall contour matches the inner wall contour of the first connecting post 39. Therefore, the second sliding post 46 can slide on the inner wall of the first connecting post 39. Furthermore, the outer wall contour of the second sliding post 46 matches the inner wall contours of the second limiting groove 12 and the first limiting groove 11, respectively. Thus, the second sliding post 46 can be inserted into the second limiting groove 12 and the first limiting groove 11, respectively. A push button 45 is fixedly connected to the side wall of the first sliding post 44. A first pulley 48 is rotatably connected to the outer wall of the first connecting post 39. The first pulley 48 is a hollow metal cylinder with an I-shaped cross-section, and its inner wall contour matches the outer wall contour of the first connecting post 39.Therefore, the first pulley 48 can rotate on the outer wall of the first connecting post 39. A handle 49 is fixedly connected to the top outer wall of the first pulley 48. By gripping the handle 49, the first pulley 48 can be rotated along the outer wall of the first connecting post 39. When the operator grips the second connecting post 40 and pushes the push button 45 with their thumb, the push button 45 will slide along the inner wall of the fifth sliding groove 42 toward the top of the second connecting post 40. At this time, the first sliding post 44 will slide along the inner wall of the second connecting post 40 toward the top of the second connecting post 40 under the action of the push button 45. At this time, the tension spring 43 will be stressed and deform along its bending direction. The second sliding column 46, driven by the first sliding column 44, slides along the inner wall of the first connecting column 39 towards the top of the second connecting column 40. The bottom end of the second sliding column 46 slides out of the first limiting groove 11, thus releasing the limiting position of the U-shaped plate 38. Then, the worker grasps the second connecting column 40 and moves it away from the fixed cylinder 7. At this time, the first connecting column 39 moves synchronously with the second connecting column 40, and the U-shaped plate 38, driven by the first connecting column 39, slides along the outer wall of the first connecting plate 10 away from the fixed cylinder 7. The first pulley 48 also moves synchronously with the first connecting column 39.

[0036] Furthermore, a first rotating protrusion 47 is fixedly connected to the bottom outer wall of the U-shaped plate 38. The first rotating protrusion 47 is a metal cylinder with a convex cross-section. A fourth connecting plate 59 and a fifth connecting plate 60 are rotatably connected to the outer wall of the first rotating protrusion 47. Both the fourth connecting plate 59 and the fifth connecting plate 60 are square metal plates. A first sliding groove 16 is provided on the top outer wall of the second connecting plate 15. The first sliding groove 16 is a square groove with arcs at both ends. A sliding protrusion 50 is slidably connected to the inner wall of the first sliding groove 16. The sliding protrusion 50 is a metal cylinder with a convex cross-section. The outer contour of the sliding protrusion 50 matches the inner contour of the first sliding groove 16, so the sliding protrusion 50 can slide on the inner wall of the first sliding groove 16. An abutment block 51 is fixedly connected to the top of the sliding protrusion 50. The abutment block 51 is a trapezoidal block, and the inclined surface on the abutment block 51 is set on the abutment block 50. On the outer wall of the fixed cylinder 7, near the central axis, the outer wall contour of the contact block 51 is adapted to the inner wall contour of the second sliding groove 17, so the contact block 51 can slide on the inner wall of the second sliding groove 17. The top of the contact block 51 is fixedly connected to a connecting protrusion 52, which is a metal cylinder with a convex cross-section. The outer wall of the connecting protrusion 52 is rotatably connected to a second pulley 53, which is a hollow metal cylinder with an I-shaped cross-section. Since the inner wall contour of the second pulley 53 is adapted to the outer wall contour of the connecting protrusion 52, the second pulley 53 can rotate on the outer wall of the connecting protrusion 52. The bottom of the sliding protrusion 50 is fixedly connected to a second rotating protrusion 54, which is a metal cylinder with a convex cross-section. The two second rotating protrusions 54 are respectively rotatably connected to the ends of the fourth connecting plate 59 and the fifth connecting plate 60 away from the first rotating protrusion 47.

[0037] When the first rotating protrusion 47 moves towards the second limiting groove 12 under the drive of the U-shaped plate 38, the first rotating protrusion 47 will drive the fourth connecting plate 59 and the fifth connecting plate 60 to move respectively. Meanwhile, the two second rotating protrusions 54, driven by the fourth connecting plate 59 and the fifth connecting plate 60 respectively, move towards the central axis of the fixed cylinder 7. At this time, the sliding protrusion 50, driven by the second rotating protrusions 54, slides along the inner wall of the first sliding groove 16 towards the central axis of the fixed cylinder 7. The abutment block 51, the connecting protrusion 52, and the second pulley 53 will move synchronously under the drive of the sliding protrusion 50. During this process, the abutment block 51 will slide along... The inner wall of the second sliding groove 17 slides towards the central axis of the fixed cylinder 7. At this time, the inclined surface on the abutment block 51 will abut against the third inclined surface 58. As the abutment block 51 abuts, the rotating plate 30 will be lifted and slide along the inner wall of the first rotating groove 9 towards the top of the fixed cylinder 7. With the above structure, the limit on the first pulley 48 can be released by pushing the push button 45. Then, by holding the second connecting column 40, the first pulley 48 can be moved. As the first pulley 48 moves, the second pulley 53 will be moved synchronously, and the rotating plate 30 will be lifted by the abutment block 51, providing conditions for the rotation of the first fixed column 25.

[0038] In this embodiment, as Figures 6 to 8As shown, a third connecting plate 13 is fixedly connected to the outer wall of the fixed cylinder 7. The third connecting plate 13 is a square metal plate. A first connecting groove 18 is formed on the outer wall of the fixed cylinder 7 near the third connecting plate 13. The first connecting groove 18 is a fan-shaped groove. A second rotating groove 14 is formed on the outer wall of the third connecting plate 13 away from the fixed cylinder 7. The second rotating groove 14 is a circular groove. A rotating column 55 is rotatably connected to the inner wall of the second rotating groove 14. The rotating column 55 is a metal cylinder with an I-shaped cross-section. Since the outer contour of the rotating column 55 matches the inner contour of the second rotating groove 14, the rotating column 55 can rotate on the inner wall of the second rotating groove 14. A third pulley 56 is rotatably connected to the outer wall of the rotating column 55. The third pulley 56 is a hollow metal cylinder with an I-shaped cross-section. The outer wall of the third pulley 56 near the bottom has several toothed grooves arranged in a circular array. The outer wall of the third pulley 56 near the bottom has a second inclined surface 57. Since the inner wall contour of the third pulley 56 matches the outer wall contour of the rotating column 55, the third pulley 56 can rotate on the outer wall of the rotating column 55. Since the outer wall contour of the third pulley 56 matches the inner wall contour of the first connecting groove 18, the first connecting groove 18 can provide clearance space for the rotation of the third pulley 56. When the rotating plate 30 is lifted as mentioned above, the toothed grooves on the outer wall of the rotating plate 30 can mesh with the toothed grooves on the third pulley 56 under the guidance of the second inclined surface 57. The same belt 37 is tensioned on the outer walls of the first pulley 48, the second pulley 53 and the third pulley 56. The belt 37 is disclosed in the prior art and will not be described in detail. When the rotating plate 30 is lifted, causing the toothed groove on the rotating plate 30 to mesh with the toothed groove on the third pulley 56, the operator holds the handle 49 and rotates the first pulley 48. The first pulley 48 will rotate along the outer wall of the first connecting column 39. As the first pulley 48 rotates, the second pulley 53 and the third pulley 56 rotate synchronously under the drive of the belt 37. At this time, the rotating plate 30 will rotate synchronously under the drive of the third pulley 56. With the above structure, the first pulley 48 can be rotated by holding the handle 49, thereby driving the third pulley 56 to rotate synchronously, providing conditions for the subsequent scraping of phosphorus-containing dust on the inner wall of the first air guide pipe 2 by the scraper plate 29.

[0039] The working principle of the technical solution provided by this invention is as follows: When in use, the phosphorus furnace gas generated in the electric furnace 1 enters the first gas guide pipe 2 along the inner wall of the fixed cylinder 7. Under the guidance of the fan plate 26, the phosphorus furnace gas will hit the inner wall of the first gas guide pipe 2, and the flow rate will be reduced. Then, the gas and solid phases will be separated by the principle of gravity settling. At this time, the phosphorus-containing dust in the phosphorus furnace gas will slowly settle under the action of gravity.

[0040] The worker holds the second connecting post 40 and pushes the push button 45 with their thumb. The push button 45 then slides along the inner wall of the fifth sliding groove 42 towards the top of the second connecting post 40. Simultaneously, the first sliding post 44, driven by the push button 45, slides along the inner wall of the second connecting post 40 towards the top of the second connecting post 40. At this time, the tension spring 43 is stressed and deforms in the direction of its bending. The second sliding post 46 follows the first sliding post 44, sliding synchronously along the inner wall of the first connecting post 39 towards the top of the second connecting post 40. The bottom end of the second sliding post 46 slides out of the first limiting groove 11, completing the release of the limiting position of the U-shaped plate 38.

[0041] Subsequently, the staff holds the second connecting column 40 and moves it away from the fixed cylinder 7. The first connecting column 39 moves synchronously with the second connecting column 40. Under the drive of the first connecting column 39, the U-shaped plate 38 slides along the outer wall of the first connecting plate 10 away from the fixed cylinder 7. The first pulley 48 also moves synchronously with the first connecting column 39.

[0042] During this process, the first rotating protrusion 47 moves towards the second limiting groove 12 along with the U-shaped plate 38, causing the fourth connecting plate 59 and the fifth connecting plate 60 to move. The two second rotating protrusions 54 move towards the central axis of the fixed cylinder 7 under the influence of the fourth connecting plate 59 and the fifth connecting plate 60. At this time, the sliding protrusion 50 slides along the inner wall of the first sliding groove 16 towards the central axis of the fixed cylinder 7 under the influence of the second rotating protrusions 54. The abutment block 51, the connecting protrusion 52, and the second pulley 53 move synchronously with the sliding protrusion 50.

[0043] During this process, the contact block 51 slides along the inner wall of the second sliding groove 17 toward the central axis of the fixed cylinder 7, and its inclined surface abuts against the third inclined surface 58. As the contact block 51 continues to push, the rotating plate 30 is lifted and slides along the inner wall of the first rotating groove 9 toward the top of the fixed cylinder 7, so that the tooth groove of the rotating plate 30 meshes with the tooth groove of the third pulley 56.

[0044] Simultaneously, the third fixed post 28 moves synchronously with the rotating plate 30, and drives the second fixed post 27 to slide along the inner wall of the third limiting groove 21 toward the top of the limiting cylinder 20. The first fixed post 25 slides synchronously along the inner wall of the limiting cylinder 20 under the drive of the second fixed post 27. The fan plate 26 and the fixed protrusion 24 move synchronously with the first fixed post 25, and the spring 23 is bent and deformed under force until the second fixed post 27 slides completely out of the inner wall of the third limiting groove 21, releasing the limiting constraint of the second fixed post 27 on the first fixed post 25.

[0045] Then, the operator holds the handle 49 and rotates the first pulley 48, which rotates along the outer wall of the first connecting column 39. Under the transmission action of the belt 37, the second pulley 53 and the third pulley 56 will rotate synchronously, and the third pulley 56 will drive the rotating plate 30 to rotate synchronously.

[0046] As the rotating plate 30 rotates, it causes the third fixed column 28 to slide synchronously along the inner wall of the first rotating groove 9. The top of the third fixed column 28 slides along the inner wall of the third sliding groove 36, while the scraper plate 29 rotates synchronously with the third fixed column 28. At this time, the outer wall of the scraper plate 29 away from the third fixed column 28 adheres to the inner wall of the first air guide pipe 2, and scrapes off the phosphorus-containing dust adhering to the inner wall of the first air guide pipe 2 during the rotation.

[0047] Meanwhile, the second fixed column 27, driven by the third fixed column 28, rotates around the central axis of the fixed cylinder 7. The first fixed column 25, driven by the second fixed column 27, rotates along the inner wall of the limiting cylinder 20, and the fan plate 26 rotates synchronously with the first fixed column 25. During the rotation, the fan plate 26 can draw the scraped phosphorus-containing dust into the furnace for re-evaporation and reuse.

To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0049] The above description is only a preferred embodiment of the present invention.
