Description

Technical Field

[0001] This invention belongs to the field of pipeline cleaning technology, specifically a dust removal device for flue gas emission pipelines based on silicon metal smelting. Background Technology

[0002] As one of the most polluting industries, the silicon metal smelting industry faces increasingly stringent emission standards. To meet environmental regulations, silicon metal smelting companies need to develop efficient exhaust duct systems to ensure that flue gas emissions comply with standards. When exhaust duct systems discharge flue gas, the resulting dust particles, especially silica dust, are present. Silica dust has strong adsorption properties; as the flue gas passes through the exhaust duct system, the silica dust adheres to the inner wall of the duct. Excessive accumulation of silica dust occupies the exhaust channel area, affecting the exhaust efficiency. Therefore, a dust scraper is needed to scrape the dust off the inner wall of the exhaust duct. Chinese Patent Publication No. CN215089497U discloses a dust removal device and a single crystal furnace dust removal device for cleaning pipelines. The dust removal device includes a driving component, a transmission component, and a dust removal component. Through the coordinated arrangement of the driving component and the transmission component, the dust removal component can be driven to slide along the inner wall of the pipeline. Since the dust removal component at least partially abuts against the inner wall of the pipeline, the deposits on the inner wall of the pipeline can be cleaned through friction, thus achieving automatic cleaning of the pipeline's inner wall. In existing technologies, a scraper is mainly used to remove silica dust adhering to the pipe wall. However, since silica dust is adhesive, when the scraper removes the dust, the silica dust will stick to the scraper. As the scraping operation continues, the amount of dust adhering to the scraper surface increases, and the scraping effect deteriorates. At this point, the scraper needs to be cleaned and the scraping operation repeated, which is inefficient.

[0003] Therefore, the present invention provides a dust removal device for flue gas emission pipelines based on silicon metal smelting. Summary of the Invention

[0015] The beneficial effects of this invention are as follows: 1. The dust removal device for flue gas emission pipelines based on silicon metal smelting, as described in this invention, uses a scraper to scrape dust from the inner wall of the pipeline. During the scraping process, adhering silica dust accumulates on the scraper, affecting its effectiveness. This invention addresses this by using a scraper blade that adheres to the scraper blade, allowing the blade and scraper to slide relative to each other during scraping. This allows the scraper blade to remove the adhering silica dust. Simultaneously, a brush plate further cleans the scraper blade, improving its cleaning efficiency. Furthermore, the scraper blade can intermittently scrape the scraper blade during the process, avoiding the need to stop the device for cleaning and thus improving the overall efficiency of pipeline cleaning.

[0016] 2. The dust removal device for flue gas emission pipelines based on silicon metal smelting described in this invention addresses the issue that when the scraper removes silica dust adhering to the scraper plate, some of the removed silica dust also adheres to the scraper. Therefore, when the scraper cleans the scraper plate, a rocker plate is installed to strike the scraper as the scraper plate moves towards the axis of the guide seat. The rocker plate can continuously strike the scraper, making the removed silica dust fall off better and preventing secondary adhesion of silica dust, thereby improving the effect and efficiency of pipeline dust removal.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 9As shown, an embodiment of the present invention provides a dust removal device for flue gas emission pipes based on silicon metal smelting, including a hanging base 1. A guide seat 5 is fixedly connected to one end of the hanging base 1. A rotating base 2 is rotatably connected to the outside of the hanging base 1 and above the guide seat 5. Three support members 3 are fixedly connected to the outer surface of the rotating base 2. A fixing frame 4 is fixedly connected to one end of each of the three support members 3. The three fixing frames 4 are arranged in a ring array outside the rotating base 2. A scraper plate 6 is provided inside the fixing frame 4 on the side away from the hanging base 1. A scraper 11 is provided inside the fixing frame 4 on the side close to the scraper plate 6. One end of the scraper 11 is attached to the scraper plate 6. The guide seat 5 consists of a dust wiping position 29 and a cleaning position 30. There are three dust wiping positions 29 and three cleaning positions 30. The three dust wiping positions 29 and the cleaning positions 30 are staggered and their connection points are smoothly connected by an arc-shaped surface. During operation, this device is used to clean the inner wall of a cylindrical pipe. Before using this device to clean the pipe, the device is first hoisted by a winch. After hoisting, the device is put into the pipe from the top to start cleaning. Before the device is put into the pipe to be cleaned, the initial position of the scraper 6 is at the cleaning position 30, which makes it easy to put the device into the pipe to be cleaned. After being put in, the scraper 6 is driven to move to the wiping position 29. At this time, the scraper 6 can stick to the pipe wall to scrape the ash. During dust removal, when the device enters the pipe to be cleaned via a winch, it stops descending after entering and drives the scraper blades 6 to rotate one revolution inside the pipe. Since the circumferential angles of the three wiping positions 29 and the cleaning position 30 are all 60°, the three scraper blades 6 clean a 180° area inside the pipe wall. After cleaning, the device rotates 60° inside the pipe. At this time, the three scraper blades 6 rotate to another 180° area inside the pipe, and then drive the scraper blades 6 to rotate one revolution inside the pipe. This allows the rotating scraper blades 6 to clean another 180° area inside the pipe wall, thus enabling 360° cleaning of the pipe. After cleaning, the winch drives the device to descend again to the second cleaning position, allowing the scraper blades 6 to clean the second cleaning position again. This process is repeated to clean the pipe. Because the flue gas from the dust emission pipes used in silicon metal smelting contains a large amount of silica dust, and silica dust is highly adhesive, it easily adheres to the pipe wall during the emission process. Therefore, this application uses a scraper 6 to clean the silica dust adhering to the pipe wall. However, when the scraper 6 cleans the pipe wall, silica dust will adhere and accumulate on the scraper 6, thus affecting the scraping effect. Therefore, the scraper 6 needs to be cleaned to enable it to scrape dust better. In the prior art, as the scraping operation proceeds, the amount of dust adhering to the surface of the scraper 6 increases, and the scraping effect deteriorates. At this time, the scraper 6 needs to be cleaned and the scraping operation repeated, which is inefficient. During the process of the scraper blade 6 rotating and cleaning inside the pipe, when the scraper blade 6 enters the area of ​​the shaving position 29, the scraper blade 6 can adhere to the pipe wall to clean the dust. When the scraper blade 6 enters the area of ​​the cleaning position 30, the scraper blade 6 can detach from the pipe wall and then clean the pipe. When using the 11 scraper blades 6 for cleaning, the scraper blades 6 first rotate one full circle, cleaning half of the pipe's circumference. That is, while the hanger 1 drives the three scraper blades 6 to rotate and scrape dust inside the pipe, the guide seat 5 allows the three scraper blades 6 to move radially. When the scraper blade 6 moves in a circular motion along the wiping position 29, it remains in contact with the pipe wall, scraping away dust. When the direction of the scraper blade 6's circular motion changes from the wiping position 29 to the cleaning position 30, the guide seat 5 pulls the scraper blade 6 back and forth radially once. When the scraper blade 6 moves towards the guide seat 5, the scraper... The ash scraper 6 detaches from the pipe wall and stops scraping. The scraper blade 11 can adhere to the surface of the ash scraper 6 to scrape and clean. After cleaning, the ash scraper 6 returns to its original position until the direction of the circumferential movement of the ash scraper 6 returns to the direction of the ash wiping position 29. At this time, the ash scraper 6 continues to adhere to the pipe wall to scrape ash. When the ash scraper 6 returns to its original position, the entire device rotates 60°. At this time, the ash scraper 6 is driven to rotate one revolution inside the pipe wall again, which can clean the other half of the pipe wall area. This process is repeated to allow the ash scraper 6 to scrape ash from the pipe and to facilitate the cleaning of the ash adhering to the surface of the ash scraper 6. After cleaning, the ash scraper 6 can repeat the ash scraping operation, thereby improving the efficiency of pipe cleaning.

[0022] like Figure 1 and Figure 2 As shown, a mounting bracket 7 is fixedly connected to the side of the scraper blade 6 near the guide seat 5, and a push-pull rod 9 is fixedly connected to the side of the mounting bracket 7 away from the scraper blade 6. A sliding seat 10 is rotatably connected to the end of the push-pull rod 9 away from the mounting bracket 7, and the sliding seat 10 is movably connected to the guide seat 5. During operation, the push-pull rod 9 is used to connect the guide seat 5 and the scraper plate 6. The push-pull rod 9 is fixedly installed between the scraper plate 6 and the mounting bracket 7. The push-pull rod 9 is movably installed between the guide seat 5 and the sliding seat 10. When the scraper plate 6 makes a circular motion, the push-pull rod 9 connected to the scraper plate 6 moves back and forth radially under the guidance of the guide seat 5, so that the scraper plate 6 can move back and forth radially along the guide seat 5 during the circular motion.

[0023] like Figure 4 As shown, the mounting bracket 7 is located inside the fixed bracket 4. Two first sliding rods 8 are fixedly connected to the mounting bracket 7. The two first sliding rods 8 are movably connected to the fixed bracket 4. The push-pull rod 9 is movably connected to the fixed bracket 4. During operation, the two first sliding rods 8 fixed on the mounting frame 7 can move through the fixed frame 4. When the push-pull rod 9 pulls the connected mounting frame 7 to move inside the fixed frame 4, the two first sliding rods 8 guide the moving fixed frame 4, so that the scraper plate 6 fixed on the mounting frame 7 can move stably.

[0024] like Figure 1 , Figure 2 and Figure 9 As shown, the sliding seat 10 slides along the direction of the dust removal position 29 and the cleaning position 30. The guide seat 5 is provided with three guide rail grooves, and the sliding seat 10 is provided with three pulleys. The three pulleys roll in the three guide rail grooves respectively. During operation, the three pulleys on the sliding seat 10 can roll in the three guide rail grooves respectively, allowing the sliding seat 10 to move along the direction of the dust removal position 29 and the cleaning position 30. The sliding seat 10 will pull the connected push-pull rod 9 to move, which in turn will cause the push-pull rod 9 to drive the dust scraper 6 to move back to its original position.

[0025] like Figure 4 and Figure 7 As shown, a rotating rod 12 is fixedly connected to the scraper 11. The rotating rod 12 is rotatably connected to the fixed frame 4. Both ends of the rotating rod 12 are fixedly connected to the extrusion arms 13. Openings 16 are provided on both sides of the fixed frame 4. A second sliding rod 14 is fixedly connected inside the opening 16. One end of the extrusion arm 13 is movably connected to the second sliding rod 14. One end of the second sliding rod 14 is fixedly connected to a first spring 15. One end of the first spring 15 is fixedly connected to the extrusion arm 13. During operation, one end of the scraper 11 is fixedly connected to the rotating rod 12, and the other end of the scraper 11 can adhere to the outer surface of the scraper plate 6 for scraping and cleaning. The rotating rod 12 can rotate on the fixed frame 4. One end of each of the two squeezing arms 13 is fixed to one end of the rotating rod 12, and the other end of the squeezing arms 13 can swing around the rotating rod 12 on the second slide rod 14, compressing the first spring 15. The compressed first spring 15 will generate elasticity, and the elastic force will keep the scraper 11 in contact with the scraper plate 6. When the scraper blade 6 is displaced, the scraper 11 can clean the silica dust adhering to the scraper blade 6. It should be noted that when the scraper blade 6 is displaced into the fixed frame 4, the scraper 11 will be displaced to the front of the scraper blade 6 before it starts to move back, so as to completely scrape off the silica dust adhering to the scraper blade 6. When the scraper blade 6 behind the scraper 11 starts to return to its original position, the scraper blade 6 will lift the scraper 11. Under the elastic action of the first spring 15, the scraper 11 can always be attached to the outer surface of the scraper blade 6.

[0026] like Figure 6As shown, a brush plate 26 is provided below the scraper 11. The brush plate 26 is attached to the top of the scraper plate 6 for wiping dust. A fourth slide rod 27 is rotatably connected to the brush plate 26. The fourth slide rod 27 is movably connected to the scraper 11. A fourth spring 28 is fixedly connected to both ends of the fourth slide rod 27 through the scraper 11. The fourth spring 28 is fixedly connected to the top of the scraper 11. During operation, the brush plate 26 can adhere to the outer surface of the scraper plate 6 for secondary scraping, which can improve the cleaning effect of the scraper 11. Since the brush plate 26 is movably connected to the scraper 11 through the fourth slide rod 27, the fourth spring 28 fixed on the fourth slide rod 27 presses against the scraper 11. The compressed fourth spring 28 will generate a reaction force, which will push the brush plate 26 to always adhere to the surface of the scraper plate 6. Thus, when the scraper plate 6 moves back to its original position, the brush plate 26 can wipe the scraper plate 6. It should be noted that during the process of the scraper plate 6 moving back to its original position, the brush plate 26 always adheres to the scraper plate 6. When the scraper plate 6 moves to the deepest part of the fixed frame 4, the brush plate 26 will not detach from the scraper plate 6, so that the brush plate 26 and the scraper plate 6 always maintain contact and relative displacement.

[0027] like Figure 4 and Figure 8 As shown, a rocker arm 17 is rotatably connected to the fixed frame 4. A through-hole is provided on the mounting frame 7. The rocker arm 17 is movably connected to the mounting frame 7 through the through-hole. The rocker arm 17 consists of a striking end 18 and a pressing end 19. One end of the striking end 18 is attached to the scraper 11 through a metal ball. One end of the pressing end 19 is fixedly connected to a second spring 20, and one end of the second spring 20 is fixedly connected to the fixed frame 4. Four second wedge blocks 31 are provided on the pressing end 19. A rotating plate 21 is rotatably connected to one end of the mounting bracket 7 away from the scraper plate 6. A first wedge block 22 is provided at one end of the rotating plate 21, and the first wedge block 22 is located above the wiping position 29. During operation, the rocker arm 17 strikes the scraper 11 when the scraper plate 6 moves towards the axis of the guide seat 5. Specifically, when the scraper plate 6 moves, it drives the scraper plate 6 towards the axis of the guide seat 5, and the mounting frame 7 moves synchronously with the scraper plate 6. The mounting frame 7 then drives the connected rotating plate 21 to move. When the first wedge block 22 on the rotating plate 21 begins to contact the first second wedge block 31 on the pressing end 19, the first wedge block 22 presses the rocker arm 17 to rotate on the fixed frame 4. The rotating rocker arm 17 causes the striking end 18 to tilt upwards, and the pressing end... 19 will compress the connected second spring 20 until the first wedge block 22 disengages from the first second wedge block 31. At this time, the compressed second spring 20 will quickly spring up, thereby pushing the rocker 17 to rotate rapidly, so that the striking end 18 can strike the scraper 11. After the strike, the first wedge block 22 will squeeze the second first wedge block 22 again, thereby causing the rocker 17 to rotate and strike again. Thus, when the scraper 11 scrapes the relatively displaced scraper plate 6, the rocker 17 can continuously strike the scraper 11, so that the scraped silica dust can be better removed.

[0028] like Figure 8 As shown, the rotating plate 21 is provided with two sets of reset mechanisms. The reset mechanisms are used to reset the rotating plate 21. The reset mechanism includes a third slide rod 23. One end of the third slide rod 23 is fixedly connected to the fixed frame 4, and the other end of the third slide rod 23 is movably connected to the rotating plate 21. A third spring 24 is fixedly connected to one end of the third slide rod 23 that passes through the rotating plate 21. One end of the third spring 24 is fixedly connected to the rotating plate 21. During operation, when the first wedge block 22 moves behind the last second wedge block 31, the mounting frame 7 will reset along with the scraper plate 6. The mounting frame 7 will drive the connected rotating plate 21 to reset. During the reset process, the second wedge block 31 will press the first wedge block 22 in the opposite direction. The pressed first wedge block 22 will drive the rotating plate 21 to rotate on the mounting frame 7. The two third sliding rods 23 fixed on the mounting frame 7 will guide the rotating plate 21 and compress the third spring 24 sleeved on the third sliding rod 23. The compressed third spring 24 will push the rotating plate 21 to reset, so that when the rotating plate 21 moves again, it can continue to press the rocker plate 17. This process is repeated, so that when the scraper 11 scrapes the scraper plate 6, the rocker plate 17 will continuously tap the scraper 11, thereby improving the scraping and cleaning effect of the scraper plate 6.

[0029] like Figure 3 As shown, a roller 25 is rotatably connected to the above-mentioned fixed frame 4. The roller 25 is located above the scraper plate 6, and a number of balls are provided on the outer surface of the roller 25. During operation, when the fixed frame 4 drives the connected scraper blade 6 to rotate and scrape dust against the inner wall of the pipe, the rotating roller 25 on the fixed frame 4 can roll against the inner wall of the pipe. The rolling mechanism on the roller 25 allows it to rotate laterally when the pipe is raised or lowered, thus keeping the device stable when it descends and scrapes dust inside the pipe. In other words, the scraper blade 6 can stably stick to the inner wall of the pipe to scrape dust, and the scraped dust can fall into the dust collection chamber connected to the exhaust pipe.

[0030] Work process: By activating the power assembly on the hanger 1, the power assembly drives the rotating seat 2 to rotate on the hanger 1. The power assembly is existing technology and mainly provides power for the rotation of the rotating seat 2, so it will not be described in detail in this article. The power assembly consists of components such as a servo motor, controller, and gears. The servo motor drives the rotating seat 2 to rotate on the hanger 1 through the gear assembly. The rotating seat 2 drives the three connected scraper blades 6 to move through the three support members 3 respectively. The three scraper blades 6 make circular motion around the hanger 1 as the axis. The circularly moving scraper blades 6 can fit against the inner wall of the pipe to be cleaned to scrape the ash. During the process of the hanging seat 1 driving the three scraper blades 6 to rotate and scrape dust inside the pipe, the guide seat 5 can drive the three scraper blades 6 to move radially. That is, when the scraper blade 6 moves in a circle along the direction of the wiping position 29, the scraper blade 6 remains attached to the pipe wall and can scrape dust from the pipe wall. When the direction of the scraper blade 6's circular movement changes from the wiping position 29 to the cleaning position 30, the guide seat 5 will pull the scraper blade 6 to move back and forth radially once. When the scraper blade 6 moves towards the guide seat 5, the scraper blade 6 will detach from the pipe wall and stop scraping dust. The scraper blade 11 can adhere to the surface of the scraper blade 6 to scrape and clean. After cleaning, the scraper blade 6 will reset until the direction of the scraper blade 6's circular movement returns to the direction of the wiping position 29. At this time, the scraper blade 6 will continue to adhere to the pipe wall to scrape dust. This process is repeated, so that the scraper blade 6 can scrape dust and clean during the circular movement. During the cleaning process of the scraper plate 6, the brush plate 26 can adhere to the outer surface of the scraper plate 6 to scrape the dust, which can improve the cleaning effect of the scraper 11. Since the brush plate 26 is movably connected to the scraper 11 through the fourth slide rod 27, the fourth spring 28 fixed on the fourth slide rod 27 presses against the scraper 11. The compressed fourth spring 28 will generate a reaction force, which will push the brush plate 26 to always adhere to the surface of the scraper plate 6. Thus, when the scraper plate 6 moves back to the reset position, the brush plate 26 can wipe the dust off the scraper plate 6. It should be noted that the brush plate 26 always adheres to the scraper plate 6 during the process of the scraper plate 6 moving back to the reset position. When the scraper plate 6 moves to the deepest part of the fixed frame 4, the brush plate 26 will not detach from the scraper plate 6, so that the brush plate 26 and the scraper plate 6 always maintain contact and relative displacement. Simultaneously, the rocker arm 17 can strike the scraper 11 when the scraper plate 6 moves towards the axis of the guide seat 5. That is, when the scraper plate 6 moves, it will drive the scraper plate 6 to move towards the axis of the guide seat 5. The mounting frame 7 will move synchronously with the scraper plate 6. The mounting frame 7 will drive the connected rotating plate 21 to move. When the first wedge block 22 on the rotating plate 21 begins to fit against the first second wedge block 31 on the extrusion end 19, the first wedge block 22 will squeeze the rocker arm 17 to rotate on the fixed frame 4. The rotating rocker arm 17 causes the striking end 18 to tilt up, and the extrusion end... 19 will compress the connected second spring 20 until the first wedge block 22 disengages from the first second wedge block 31. At this time, the compressed second spring 20 will quickly spring up, thereby pushing the rocker 17 to rotate rapidly, so that the striking end 18 can strike the scraper 11. After the strike, the first wedge block 22 will squeeze the second first wedge block 22 again, thereby causing the rocker 17 to rotate and strike again. Thus, when the scraper 11 scrapes the relatively displaced scraper plate 6, the rocker 17 can continuously strike the scraper 11, so that the scraped silica dust can be better removed.
