Description

Technical Field

[0001] This invention relates to the field of continuous casting furnace technology, specifically to a dust removal and protection device for the charging port of a continuous casting furnace used in copper tube production. Background Technology

[0002] In the copper tube production process, the continuous casting furnace is the core equipment for melting copper raw materials and forming billets. The charging process of the continuous casting furnace is a key link to ensure continuous production. This process requires frequently opening the charging port to feed copper raw materials into the furnace. During the falling process, a large amount of dust is generated due to impact and the material layer being lifted. At the same time, the high-temperature flue gas in the furnace will escape from the charging port along with the dust.

[0003] Therefore, we propose a dust removal and protection device for the charging port of a continuous casting furnace used in copper tube production. Summary of the Invention

[0004] The purpose of this invention is to provide a dust removal and protection device for the charging port of a continuous casting furnace used in copper tube production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust removal and protection device for the charging port of a continuous casting furnace for copper tube production, comprising a charging port body disposed on the top of the furnace body, a protective cover fixedly connected to the top of the charging port body, and a cover plate slidably connected to the top of the protective cover via a moving mechanism, a dust removal pipe connected to one side of the protective cover, and a filter mechanism disposed at the inlet of the dust removal pipe.

[0006] Preferably, the moving mechanism includes a mounting plate fixedly connected to the side wall of the protective cover, and two symmetrically arranged cylinders are fixedly connected to the top of the mounting plate. Each cylinder includes a piston rod, which is connected to the cover plate through a connecting mechanism. The side wall of the protective cover is provided with a guide mechanism for guiding the movement of the cover plate.

[0007] By adopting the above technical solution, the cylinder is activated, causing the piston rod to retract, which in turn drives the cover plate to move through the connecting mechanism, thereby realizing the opening and closing of the top of the protective cover.

[0008] Preferably, the guiding mechanism includes two symmetrically arranged support plates fixedly connected to the side wall of the protective cover, and the support plates extend to the top of the mounting plate. The top of the support plates is provided with a limiting groove, and the top of the cover plate is detachably connected to multiple mounting blocks through the mounting mechanism. The side wall of each mounting block is rotatably connected to a roller through a rotating mechanism, and the roller rolls in the limiting groove.

[0009] By adopting the above technical solution, when the cover plate moves, the mounting block can be moved by the mounting mechanism, and the roller can be driven to roll in the limiting groove by the rotating mechanism. This can guide and support the movement of the cover plate, making the movement of the cover plate more stable and reliable.

[0010] Preferably, the mounting mechanism includes a support block fixedly connected to the top of the cover plate, and the mounting block is detachably connected to the support block by bolts.

[0011] By adopting the above technical solution, it is convenient to install and disassemble the mounting block.

[0012] Preferably, the rotating mechanism includes two symmetrically arranged first fixing blocks fixedly connected to the bottom of the mounting block, and the roller is rotatably connected to the side wall of the first fixing block through a rotating shaft.

[0013] By adopting the above technical solution, the normal rotation of the roller is guaranteed.

[0014] Preferably, the connecting mechanism includes a connecting plate fixedly connected to the side wall of one of the mounting blocks, and two second fixing blocks fixedly connected to the bottom of the connecting plate. The end of the piston rod is fixedly connected to a first connecting block, and the first connecting block is connected to the second fixing block by a pin.

[0015] By adopting the above technical solution, the connection between the piston rod and the mounting block is ensured, thereby enabling the cover plate to move.

[0016] Preferably, a reinforcing mechanism is provided at the top of the cover plate. The reinforcing mechanism includes a first horizontal plate and a second horizontal plate fixedly connected to the top of the cover plate, and two vertical plates are fixedly connected between the first horizontal plate and the second horizontal plate, and a third horizontal plate is fixedly connected between the two vertical plates.

[0017] By adopting the above technical solution, and by setting a first horizontal plate, a second horizontal plate, a vertical plate, and a third horizontal plate on the top of the cover plate, the strength of the cover plate can be increased, preventing it from warping during use and ensuring its movement and protective effect.

[0018] Preferably, the filtration mechanism includes a filter screen fixedly connected to the inlet of the dust removal pipe, and a scraper is connected to the side wall of the filter screen through a reset mechanism. The scraper is raised and lowered by a pushing mechanism.

[0019] By adopting the above technical solution, large impurities such as slag and incompletely crushed raw material particles will be present during the feeding process. The filter screen can directly intercept these large particles, preventing them from entering the dust collection pipeline. This prevents pipeline blockage, fan impeller wear or jamming, and protects the subsequent filter bags and filter elements from being scratched or damaged by hard objects. Furthermore, the pushing and resetting mechanisms can drive the scraper to move up and down. On the one hand, it can scrape and clean the surface of the filter screen, ensuring the efficiency and effect of dust collection. On the other hand, when the cover is closed, the scraper can locally seal the filter screen, reducing the suction area and matching the need for treating small amounts of flue gas after the cover is closed. This enables the dust collection system to operate at low load and high efficiency, allowing the fan to reduce its speed or maintain a basic air volume, significantly reducing power consumption per unit time. At the same time, it reduces the processing load of dust collection media such as filter bags and filter elements, extending their service life and reducing equipment maintenance and consumable replacement costs.

[0020] Preferably, the reset mechanism includes a second connecting block fixedly connected to the inner wall of the protective cover, and two sleeves fixedly connected to the top of the second connecting block. Each sleeve is fitted with a sleeve rod, and a third connecting block is fixedly connected to the upper end of the sleeve rod. The third connecting block is fixed to the side wall of the scraper, and the sleeve rod is connected to the sleeve through a spring.

[0021] By adopting the above technical solution, the raising and lowering of the scraper can be guided and reset.

[0022] Preferably, the pushing mechanism includes a fourth connecting block fixedly connected to the side wall of the scraper, and a connecting rod fixedly connected to the top of the fourth connecting block. A tapered rod is fixedly connected to the upper end of the connecting rod, and a ball is provided at the upper end of the tapered rod. The cover plate can slide on the side wall of the tapered rod and the ball.

[0023] By adopting the above technical solution, when the cover plate is moved open, the ball bearings can roll at the bottom of the cover plate. After the cover plate is fully opened, the ball bearings disengage from the bottom of the cover plate. At this time, the sleeve rod can move upward along the sleeve under the action of the spring. At the same time, the scraper is driven upward and moved above the filter screen through the third connecting block, so that the scraper is disengaged from the filter screen. At this time, the filter screen is fully opened, and the dust removal pipe is used for dust extraction. This ensures that the filter screen is fully opened when feeding, ensuring the efficiency and effect of dust extraction. When the cover plate is moved closed, when the cover plate abuts against the side wall of the conical rod, it can push the conical rod and the ball bearings downward. At the same time, the scraper is driven downward through the connecting rod and the fourth connecting block, and the sleeve rod is driven downward along the sleeve through the third connecting block. The spring is compressed. When the ball bearings move to the bottom of the cover plate, they can roll at the bottom of the cover plate. When the scraper moves downward, it can scrape and clean the surface of the filter screen, ensuring the efficiency and effect of dust extraction. In addition, the scraper can seal the filter screen locally.

[0024] In summary: Advantage 1: When adding materials, the top of the protective cover is opened to facilitate the material addition operation. After the material addition is completed, the cover is moved and closed by the moving mechanism, which can seal and protect the top of the protective cover. Advantage 2: When the cover plate moves, it can guide and support the movement of the cover plate, making the movement of the cover plate more stable and reliable. In addition, it can increase the strength of the cover plate, prevent it from warping during use, and ensure its movement and protection effects. Advantage 3: The dust collection system utilizes dust extraction ducts to ensure that the filter screen is fully open during material feeding, guaranteeing efficient and effective dust collection. When the cover is moved and closed, the surface of the filter screen can be scraped and cleaned, ensuring efficient and effective dust collection. Furthermore, the scraper can partially seal the filter screen, reducing the suction area and matching the need for handling small amounts of smoke after the cover is closed, thus achieving low-load and high-efficiency operation of the dust collection system.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-7 The figure shows a dust removal and protection device for the charging port of a continuous casting furnace used in copper tube production. It includes a charging port body 101 located at the top of the furnace body 1, which is known in this technical field and will not be described in detail here. A protective cover 11 is fixedly connected to the top of the charging port body 101, and a cover plate 12 is slidably connected to the top of the protective cover 11 via a moving mechanism. A dust removal pipe 13 is connected to one side of the protective cover 11, and a filter mechanism is installed at the inlet of the dust removal pipe 13. The dust removal pipe 13 is connected to an external fan and dust removal medium (such as filter bags or filter elements) (not shown in the figure), which is also known in this technical field and will not be described in detail here. During charging, the top of the protective cover 11 is opened to facilitate the charging operation. After charging is completed, the cover plate 12 is moved and closed by the moving mechanism. The cover 11 can be sealed and protected at the top. When the cover 12 moves, it can guide and support the movement of the cover 12, making the movement of the cover 12 more stable and reliable. It can also increase the strength of the cover 12, prevent it from warping during use, and ensure its movement and protection effect. The dust removal pipe 13 is used for exhaust and dust collection. When feeding, the filter screen 801 is fully opened to ensure the efficiency and effect of dust collection. When the cover 12 moves and closes, the surface of the filter screen 801 can be scraped and cleaned to ensure the efficiency and effect of dust collection. Furthermore, the scraper 802 can partially seal the filter screen 801 to reduce the suction area and match the needs of handling small amounts of smoke after the cover 12 is closed, so as to achieve low-load and high-efficiency operation of the dust removal system.

[0029] The moving mechanism includes a mounting plate 201 fixedly connected to the side wall of the protective cover 11, and two symmetrically arranged cylinders 202 are fixedly connected to the top of the mounting plate 201. Each cylinder 202 includes a piston rod 203, which is connected to the cover plate 12 through a connecting mechanism. The side wall of the protective cover 11 is provided with a guide mechanism for guiding the movement of the cover plate 12. When the cylinder 202 is activated, the piston rod 203 retracts, thereby driving the cover plate 12 to move through the connecting mechanism, thus realizing the opening and closing of the top of the protective cover 11.

[0030] The guiding mechanism includes two symmetrically arranged support plates 301 fixedly connected to the side wall of the protective cover 11, and the support plates 301 extend to the top of the mounting plate 201. The top of the support plates 301 is provided with a limiting groove 302, and the top of the cover plate 12 is detachably connected to multiple mounting blocks 304 through the mounting mechanism. The side wall of each mounting block 304 is rotatably connected to a roller 303 through a rotating mechanism, and the roller 303 rolls in the limiting groove 302. When the cover plate 12 moves, the mounting blocks 304 can be moved by the mounting mechanism, and the rollers 303 can be rolled in the limiting groove 302 by the rotating mechanism. This can guide and support the movement of the cover plate 12, making the movement of the cover plate 12 more stable and reliable.

[0031] The mounting mechanism includes a support block 401 fixedly connected to the top of the cover plate 12, and a mounting block 304 is detachably connected to the support block 401 by bolts 402, which facilitates the installation and removal of the mounting block 304.

[0032] The rotating mechanism includes two symmetrically arranged first fixing blocks 501 fixedly connected to the bottom of the mounting block 304, and the roller 303 is rotatably connected to the side wall of the first fixing block 501 through the rotating shaft 502 to ensure the normal rotation of the roller 303.

[0033] The connecting mechanism includes a connecting plate 601 fixedly connected to the side wall of one of the mounting blocks 304, and two second fixing blocks 602 fixedly connected to the bottom of the connecting plate 601. The end of the piston rod 203 is fixedly connected to a first connecting block 603, and the first connecting block 603 is connected to the second fixing block 602 through a pin 604 to ensure the connection between the piston rod 203 and the mounting block 304, thereby enabling the cover plate 12 to move.

[0034] A reinforcing mechanism is provided on the top of the cover plate 12. The reinforcing mechanism includes a first horizontal plate 701 and a second horizontal plate 702 fixedly connected to the top of the cover plate 12. Two vertical plates 703 are fixedly connected between the first horizontal plate 701 and the second horizontal plate 702, and a third horizontal plate 704 is fixedly connected between the two vertical plates 703. By providing the first horizontal plate 701, the second horizontal plate 702, the vertical plates 703 and the third horizontal plate 704 on the top of the cover plate 12, the strength of the cover plate 12 can be increased, preventing it from warping during use and ensuring its movement and protective effect.

[0035] The filtration mechanism includes a filter screen 801 fixedly connected to the inlet of the dust removal pipe 13, and a scraper 802 is connected to the side wall of the filter screen 801 through a reset mechanism. The scraper 802 is raised and lowered by a pushing mechanism. During the feeding process, large impurities such as slag and incompletely crushed raw material particles will be present. The filter screen 801 can directly intercept these large particles, preventing them from entering the dust collection duct 13. This prevents duct blockage, fan impeller wear or jamming, and protects the subsequent filter bags and filter elements from being scratched or damaged by hard objects. Furthermore, the pushing and resetting mechanisms can drive the scraper 802 to move up and down. On the one hand, it can scrape and clean the surface of the filter screen 801, ensuring the efficiency and effect of dust collection. On the other hand, when the cover plate 12 is closed, the scraper 802 can locally seal the filter screen 801, reducing the suction area and matching the needs of handling small amounts of flue gas after the cover plate 12 is closed. This enables the dust collection system to operate at low load and high efficiency, allowing the fan to reduce its speed or maintain a basic air volume, significantly reducing power consumption per unit time. At the same time, it reduces the processing load of the dust collection media (such as filter bags and filter elements), extends their service life, and reduces equipment maintenance and consumable replacement costs.

[0036] The reset mechanism includes a second connecting block 901 fixedly connected to the inner wall of the protective cover 11, and two sleeves 902 fixedly connected to the top of the second connecting block 901. Each sleeve 902 is fitted with a sleeve rod 903, and a third connecting block 904 is fixedly connected to the upper end of the sleeve rod 903. The third connecting block 904 is fixed to the side wall of the scraper 802, and the sleeve rod 903 is connected to the sleeve 902 by a spring, which guides and resets the scraper 802.

[0037] The pushing mechanism includes a fourth connecting block 1001 fixedly connected to the side wall of the scraper 802, and a connecting rod 1002 fixedly connected to the top of the fourth connecting block 1001. A tapered rod 1003 is fixedly connected to the upper end of the connecting rod 1002, and a ball bearing 1004 is provided at the upper end of the tapered rod 1003. The cover plate 12 can slide on the side wall of the tapered rod 1003 and the ball bearing 1004. When the cover plate 12 moves open, the ball bearing 1004 can roll at the bottom of the cover plate 12. After the cover plate 12 is fully opened, the ball bearing 1004 disengages from the bottom of the cover plate 12. At this time, the sleeve rod 903 can move upward along the sleeve 902 under the action of the spring. At the same time, the scraper 802 is driven upward through the third connecting block 904 and moves to above the filter screen 801, so that the scraper 802 disengages from the filter screen 801. At this time, the filter screen 801 is opened. 01 is fully opened, and dust extraction is performed using the dust removal pipe 13 to ensure that the filter screen 801 is fully open during material feeding, thus ensuring the efficiency and effectiveness of dust extraction. When the cover plate 12 moves to close, when the cover plate 12 abuts against the side wall of the conical rod 1003, it can push the conical rod 1003 and the ball bearing 1004 downward. At the same time, the scraper 802 is driven to move downward through the connecting rod 1002 and the fourth connecting block 1001, and the sleeve rod 903 is driven to slide downward along the sleeve 902 through the third connecting block 904. The spring is compressed, and when the ball bearing 1004 moves to the bottom of the cover plate 12, it can roll at the bottom of the cover plate 12. When the scraper 802 moves downward, it can scrape and clean the surface of the filter screen 801, ensuring the efficiency and effectiveness of dust extraction. In addition, the scraper 802 can seal the filter screen 801 locally.

[0038] Working principle: When using the device, the cylinder 202 is activated during material feeding, causing the piston rod 203 to retract. This allows the cover plate 12 to move via the connecting mechanism to the top of the mounting plate 201, at which point the top of the protective cover 11 can be opened to allow for material feeding.

[0039] After the material is added, the cover plate 12 is moved and closed by the moving mechanism, which can seal and protect the top of the protective cover 11.

[0040] When the cover plate 12 moves, the mounting block 304 can be moved by the mounting mechanism, and the roller 303 can be rolled in the limiting groove 302 by the rotating mechanism. This can guide and support the movement of the cover plate 12, making the movement of the cover plate 12 more stable and reliable.

[0041] By setting a first horizontal plate 701, a second horizontal plate 702, a vertical plate 703 and a third horizontal plate 704 on the top of the cover plate 12, the strength of the cover plate 12 can be increased, preventing it from warping during use and ensuring its movement and protective effect.

[0042] Furthermore, when the cover plate 12 is moved open, the ball bearing 1004 can roll at the bottom of the cover plate 12. After the cover plate 12 is fully opened, the ball bearing 1004 disengages from the bottom of the cover plate 12. At this time, the sleeve rod 903 can move upward along the sleeve 902 under the action of the spring. At the same time, the scraper 802 is driven upward through the third connecting block 904 and moves to the top of the filter screen 801, so that the scraper 802 disengages from the filter screen 801. At this time, the filter screen 801 is fully opened, and the dust removal pipe 13 is used for dust extraction to ensure that the filter screen 801 is fully opened when feeding materials, thus ensuring the efficiency and effect of dust extraction.

[0043] When the cover plate 12 moves to close, when the cover plate 12 abuts against the side wall of the tapered rod 1003, it can push the tapered rod 1003 and the ball bearing 1004 downward. At the same time, the scraper 802 is driven to move downward through the connecting rod 1002 and the fourth connecting block 1001, and the sleeve rod 903 is driven to slide downward along the sleeve 902 through the third connecting block 904. The spring is compressed, and when the ball bearing 1004 moves to the bottom of the cover plate 12, it can roll at the bottom of the cover plate 12. When the scraper 802 moves downward, The surface of the filter 801 can be scraped and cleaned to ensure the efficiency and effectiveness of dust collection. Furthermore, the scraper 802 can locally seal the filter 801 to reduce the suction area, which matches the needs of handling small amounts of flue gas after the cover plate 12 is closed. This enables the dust removal system to operate at low load and high efficiency. The fan can reduce its speed or maintain the basic air volume, which greatly reduces the power consumption per unit time. At the same time, it reduces the processing load of the dust removal media (such as filter bags and filter elements), extends their service life, and reduces the cost of equipment maintenance and consumable replacement.
