Description

Technical Field

[0001] This utility model belongs to the field of furnace cover opening and closing technology, specifically a refining furnace cover opening and closing structure. Background Technology

[0002] A refining furnace is a device that uses physical or chemical methods to remove impurities from metals or alloys, adjust their chemical composition and microstructure, and improve the purity and performance of the metals. It is an important industrial device used for purifying, refining and adjusting the composition of metals or alloys.

[0003] A refining furnace is a complex metallurgical equipment system, and the furnace cover is an indispensable component. It is installed above the furnace body, forming a relatively enclosed space together. Through long-term use and observation, it has been found that during the metal refining process, the residual pressure inside the furnace creates a significant pressure difference, leading to increased adhesion between the furnace cover and the furnace body, making manual opening difficult.

[0004] Therefore, this utility model provides a refining furnace cover opening and closing structure. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the problems mentioned in the background technology, a refining furnace cover opening and closing structure is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A refining furnace cover opening and closing structure of this utility model includes a connecting seat; an electric push rod is mounted on the top of the connecting seat; a motor is fixedly connected to the output end of the electric push rod; a threaded rod is fixedly connected to the output end of the motor; a fixed seat is fixed in the middle of the side wall of the motor; a fixed cylinder is slidably fitted in the middle of the side wall of the fixed seat; a disassembly and assembly assembly is provided between the fixed seat and the fixed cylinder; the threaded rod rotates inside the fixed seat and the fixed cylinder; multiple fixed plates are fixed in the middle of the side wall of the fixed cylinder; the multiple fixed plates are symmetrically arranged on the side wall of the fixed cylinder; multiple gears are meshed with the threaded rod; the gears and fixed plates are correspondingly arranged; a clamping plate is fixed in the middle of the side wall of the gear; The clamping plate and the fixing plate are rotatably connected; a buckle assembly is provided in the middle of the side wall of the clamping plate; the internal temperature of the refining furnace is extremely high during operation, and the environment around the furnace cover is also very dangerous. By setting up an electric push rod, a motor, a threaded rod, a fixing seat, a fixing cylinder, a fixing plate, gears, and clamping plates, the refining furnace cover can be opened automatically, allowing workers to operate away from the danger zone. By controlling the movement of the clamping plates, direct contact with the high-temperature environment is reduced, greatly reducing the risk of burns. In addition, the refining furnace cover is heavy, and it may fall and injure workers when it is manually handled and opened. This setting has stable clamping and lifting capabilities, and can control the movement trajectory of the furnace cover, so that the furnace cover can be opened safely and smoothly, reducing personnel injuries caused by falling heavy objects.

[0007] Preferably, multiple telescopic rods are fixed to the middle of the side wall of the clamping plate; a suction cup is fixed to the other end of the telescopic rod; a spring is fixed between the suction cup and the clamping plate; the spring is sleeved on the outside of the telescopic rod. This step of setting up the telescopic rod, suction cup and spring can generate negative pressure through the suction cup to adhere to the surface of the furnace cover, which greatly increases the friction between the clamping plate and the furnace cover, making the clamping more secure and reducing the slippage phenomenon caused by insufficient friction during the clamping process. Moreover, multiple suction cups can be evenly distributed on the surface of the furnace cover, making the force of the clamping plate on the furnace cover more uniform, ensuring that the furnace cover remains stable during opening and closing, reducing stress concentration caused by uneven force, and extending the service life of the furnace cover.

[0008] Preferably, the disassembly and assembly assembly includes a slot; the slot is formed on the side wall of the fixing seat; the slot and the fixing cylinder are correspondingly arranged; a pair of positioning blocks are fixed in the middle of the side wall of the fixing cylinder; a pair of first positioning grooves are formed in the middle of the inner side wall of the slot; the first positioning grooves and the positioning blocks are correspondingly arranged; a second positioning groove is formed in the middle of the inner side wall of the slot; the second positioning groove and the positioning block are correspondingly arranged; the second positioning groove and the first positioning groove are connected; this step, by setting the slot, positioning block, first positioning groove and second positioning groove, allows for the replacement of appropriate clamping components according to the specific shape of the refining furnace cover, so that the clamping plate fits tightly with the furnace cover, providing a stable and reliable clamping force, and reducing problems such as unstable clamping, furnace cover shaking or even falling off caused by mismatch between the clamping plate and the furnace cover.

[0009] Preferably, the buckle assembly includes multiple grooves; the grooves are formed on the side wall of the clamping plate; a fixing shaft is fixed in the middle of the inner side wall of the groove; a hook is rotatably connected to the middle of the side wall of the fixing shaft; a torsion spring is provided between the hook and the fixing shaft; this step, by setting the grooves, fixing shaft and hook, can hook the edge of the furnace cover, evenly distribute the weight of the furnace cover to multiple hooks, reduce excessive local force, make the clamping more stable, and improve the accuracy and reliability of operation.

[0010] Preferably, a protective cover is installed in the middle of the side wall of the fixed seat; the protective cover is made of a deformable material; this step can isolate the high-temperature area around the refining furnace from the personnel operation area by setting the protective cover, reducing the risk of burns to the staff, and the protective cover can effectively block the splashes of high-temperature molten metal droplets, slag and other debris when the furnace cover is opened, protecting the staff from injury.

[0011] Preferably, an anti-slip pad is fixed in the middle of the side wall of the clamping plate; the anti-slip pad is made of elastic material; this step can increase the friction between the clamping plate and the surface of the furnace cover by setting the anti-slip pad, prevent the furnace cover from sliding or falling off during operation, and further ensure that the furnace cover is stably clamped.

[0012] Preferably, the protective cover is placed outside the clamping plate; the protective cover is made of transparent material; this step, by setting a transparent protective cover, allows staff to observe the status of the furnace cover in real time, making it easier to adjust the operation in a timely manner, thereby improving production efficiency and quality.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The refining furnace lid opening and closing structure described in this utility model addresses the extremely high internal temperature and dangerous environment surrounding the furnace lid during operation of a refining furnace. By incorporating an electric push rod, motor, threaded rod, fixed base, fixed cylinder, fixed plate, gears, and clamping plate, the refining furnace lid can be automatically opened, allowing workers to operate from a distance away from the danger zone. Controlling the clamping plate's movement reduces direct contact with the high-temperature environment, significantly lowering the risk of burns. Furthermore, the refining furnace lid is heavy, and manual handling and opening could cause it to slip and injure workers. This design provides stable clamping and lifting capabilities, controlling the lid's trajectory to ensure safe and smooth opening, reducing injuries caused by falling heavy objects.

[0015] 2. The refining furnace lid opening and closing structure described in this utility model is equipped with a telescopic rod, suction cups, and springs. The suction cups can generate negative pressure to adhere to the furnace lid surface, greatly increasing the friction between the clamping plate and the furnace lid, making the clamping more secure, reducing slippage caused by insufficient friction during clamping, and the multiple suction cups can be evenly distributed on the furnace lid surface, making the force exerted by the clamping plate on the furnace lid more uniform, ensuring that the furnace lid remains stable during opening and closing, reducing stress concentration caused by uneven force, and extending the service life of the furnace lid.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 4As shown, an embodiment of the present invention provides a refining furnace cover opening and closing structure, including a connecting seat 1; an electric push rod 11 is mounted on the top of the connecting seat 1; a motor 12 is fixedly connected to the output end of the electric push rod 11; a threaded rod 13 is fixedly connected to the output end of the motor 12; a fixing seat 14 is fixed in the middle of the side wall of the motor 12; a fixing cylinder 15 is slidably fitted in the middle of the side wall of the fixing seat 14; a disassembly and assembly assembly is provided between the fixing seat 14 and the fixing cylinder 15; the threaded rod 13 rotates inside the fixing seat 14 and the fixing cylinder 15; multiple fixing plates 16 are fixed in the middle of the side wall of the fixing cylinder 15; the multiple fixing plates 16 are symmetrically arranged on the side wall of the fixing cylinder 15; the threaded rod 13 rotates inside the fixing seat 14 and the fixing cylinder 15; multiple fixing plates 16 are fixed in the middle of the side wall of the fixing cylinder 15; the threaded rod 13 rotates inside the fixing seat 14 and the fixing cylinder 15; multiple fixing plates 16 are symmetrically arranged .... The rod 13 is equipped with multiple gears 17; the gears 17 and the fixing plate 16 are correspondingly arranged; a clamping plate 18 is fixed in the middle of the side wall of the gear 17; the clamping plate 18 and the fixing plate 16 are rotatably connected; a buckle assembly is provided in the middle of the side wall of the clamping plate 18; during operation, after the operator fixes the connecting seat 1, a fixing cylinder 15 with an appropriate number of clamping plates 18 is selected according to the shape of the refining furnace cover, and it is fixed to the side wall of the fixing seat 14 using the disassembly and assembly assembly. At this time, multiple clamping plates 18 are suspended above the refining furnace cover. Then, the electric push rod 11 is activated, and the electric push rod 11 pushes the motor 12 to move down. When the motor 12 moves down, it will drive the threaded rod 13. The fixed base 14 and fixed cylinder 15 move down synchronously. At this time, the refining furnace cover is positioned between multiple clamping plates 18. Then, the motor 12 is started, and the motor 12 drives the threaded rod 13 to rotate. Because the threaded rod 13 is meshed with multiple gears 17, the gears 17 will rotate under the drive of the threaded rod 13, causing the gears 17 to drive the clamping plates 18 to rotate. At this time, the multiple clamping plates 18 will retract inward and clamp the refining furnace cover with the assistance of the snap-fit ​​assembly. Then, the motor 12 is turned off and the electric push rod 11 is started again to lift the refining furnace cover upward. The internal temperature of the refining furnace is extremely high during operation, and the environment around the furnace cover is also very dangerous. By setting... The electric actuator 11, motor 12, threaded rod 13, fixed base 14, fixed cylinder 15, fixed plate 16, gear 17, and clamping plate 18 can automatically open the refining furnace cover, allowing workers to operate from a distance away from dangerous areas. By controlling the movement of the clamping plate 18, direct contact with the high-temperature environment is reduced, greatly lowering the risk of burns. Furthermore, the refining furnace cover is quite heavy, and it could slip and injure workers if it were to be manually handled or opened. This device has stable clamping and lifting capabilities, and can control the movement trajectory of the furnace cover, ensuring that it opens safely and smoothly, reducing injuries caused by falling heavy objects.

[0026] like Figure 1 , Figure 2 and Figure 4As shown, multiple telescopic rods 2 are fixed to the middle of the side wall of the clamping plate 18; a suction cup 21 is fixed to the other end of the telescopic rod 2; a spring 22 is fixed between the suction cup 21 and the clamping plate 18; the spring 22 is sleeved on the outside of the telescopic rod 2; when the clamping plate 18 clamps the refining furnace cover from multiple directions, the multiple suction cups 21 on the side wall of the clamping plate 18 will contact the refining furnace cover and, as they continue to approach the furnace cover, they will be tightly adsorbed by the action of the spring 22. This step of setting the telescopic rod 2, suction cup 21 and spring 22 can generate negative pressure through the suction cup 21 to adsorb onto the surface of the furnace cover, which greatly increases the friction between the clamping plate 18 and the furnace cover, making the clamping more secure and reducing the slippage phenomenon caused by insufficient friction during the clamping process. Moreover, the multiple suction cups 21 can be evenly distributed on the surface of the furnace cover, making the force of the clamping plate 18 on the furnace cover more uniform, ensuring that the furnace cover remains stable during opening and closing, reducing stress concentration caused by uneven force, and extending the service life of the furnace cover.

[0027] like Figure 3 As shown, the assembly / disassembly component includes a slot 3; the slot 3 is formed on the side wall of the fixed base 14; the slot 3 and the fixed cylinder 15 are correspondingly arranged; a pair of positioning blocks 31 are fixed in the middle of the side wall of the fixed cylinder 15; a pair of first positioning grooves 32 are formed in the middle of the inner side wall of the slot 3; the first positioning grooves 32 and the positioning blocks 31 are correspondingly arranged; a second positioning groove 33 is formed in the middle of the inner side wall of the slot 3; the second positioning groove 33 and the positioning blocks 31 are correspondingly arranged; the second positioning groove 33 and the first positioning groove 32 are connected; when the refining furnace cover is polygonal, the operator will select a fixed cylinder 15 carrying an appropriate number of clamps 18 according to the shape of the furnace cover, and then align the pair of positioning blocks 31 on the side wall of the fixed cylinder 15 with the first positioning blocks 31. The slot 32 inserts the fixing cylinder 15 into the fixing seat 14. When the positioning block 31 moves into the second positioning slot 33, the fixing cylinder 15 is rotated. At this time, the fixing cylinder 15 will drive the positioning block 31 to rotate inside the second positioning slot 33, so that the positioning block 31 and the first positioning slot 32 are separated. At this time, the fixing cylinder 15 is firmly fixed on the fixing seat 14. By setting the slot 3, positioning block 31, first positioning slot 32 and second positioning slot 33, this step can replace the appropriate clamping parts according to the specific shape of the refining furnace cover, so that the clamping plate 18 fits tightly with the furnace cover, providing a stable and reliable clamping force, and reducing problems such as unstable clamping, furnace cover shaking or even falling off caused by the mismatch between the clamping plate 18 and the furnace cover.

[0028] like Figures 1 to 4As shown, the snap-fit ​​assembly includes multiple grooves 4; the grooves 4 are formed on the side wall of the clamping plate 18; a fixing shaft 41 is fixed in the middle of the inner side wall of the groove 4; a hook 42 is rotatably connected to the middle of the side wall of the fixing shaft 41; a torsion spring is provided between the hook 42 and the fixing shaft 41; when the clamping plate 18 clamps the refining furnace cover and lifts it upward, the hook 42 on the side wall of the clamping plate 18 will hook the edge of the refining furnace cover, and the misaligned hook 42 will rotate on the fixing shaft 41 and retract into the groove 4. This step, by setting the grooves 4, the fixing shaft 41 and the hooks 42, can hook the edge of the furnace cover, evenly distribute the weight of the furnace cover to multiple hooks 42, reduce excessive local force, make the clamping more stable, and improve the accuracy and reliability of the operation.

[0029] like Figure 1 As shown, a protective cover 5 is installed in the middle of the side wall of the fixed base 14; the protective cover 5 is made of deformable material; this step can isolate the high-temperature area around the refining furnace from the personnel operation area by setting the protective cover 5, reducing the risk of burns to the staff, and the protective cover 5 can effectively block the splashes of high-temperature molten metal droplets, slag and other objects when the furnace cover is opened, protecting the staff from injury.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, an anti-slip pad 6 is fixed in the middle of the side wall of the clamping plate 18; the anti-slip pad 6 is made of elastic material; this step can increase the friction between the clamping plate 18 and the surface of the furnace cover by setting the anti-slip pad 6, prevent the furnace cover from sliding or falling off during operation, and further ensure that the furnace cover is stably clamped.

[0031] like Figure 1 As shown, the protective cover 5 is installed outside the clamping plate 18; the protective cover 5 is made of transparent material; this step, by setting a transparent protective cover 5, makes it convenient for staff to observe the status of the furnace cover in real time, so as to make timely adjustments to the operation and improve production efficiency and quality.

[0032] Working principle: After the operator fixes the connecting seat 1, a fixing cylinder 15 with an appropriate number of clamping plates 18 is selected according to the shape of the refining furnace cover, and it is fixed to the side wall of the fixing seat 14 using the disassembly and assembly components. At this time, multiple clamping plates 18 are suspended above the refining furnace cover. Then, the electric push rod 11 is started, which pushes the motor 12 to move down. When the motor 12 moves down, it will drive the threaded rod 13, the fixing seat 14, and the fixing cylinder 15 to move down synchronously. At this time, the refining furnace cover is between multiple clamping plates 18. Then, the motor 12 is started, which drives the threaded rod 13 to rotate. Because the threaded rod 13 is meshed with multiple gears 17, the gears 17 will rotate under the drive of the threaded rod 13, causing the gears 17 to drive the clamping plates 18 to rotate. At this time, multiple clamping plates 18 will retract inward and clamp the refining furnace cover with the assistance of the snap-fit ​​components. Then, the motor 12 is turned off and the electric push rod 11 is started again to lift the refining furnace cover upward. When the clamping plates 18 clamp from multiple directions... When the refining furnace cover is in place, multiple suction cups 21 on the side wall of the clamping plate 18 will contact the refining furnace cover and, as they continue to approach the cover, will be tightly held in place by the spring 22. When the refining furnace cover is polygonal, the operator will select a fixing cylinder 15 carrying an appropriate number of clamping plates 18 according to the shape of the cover. Then, the operator will align a pair of positioning blocks 31 on the side wall of the fixing cylinder 15 with the first positioning groove 32 and insert the fixing cylinder 15 into the fixing seat 14. When the positioning block 31 moves into the second positioning groove 33, the fixing cylinder 15 will be rotated. At this time, the fixing cylinder 15 will drive the positioning block 31 to rotate inside the second positioning groove 33, causing the positioning block 31 to separate from the first positioning groove 32. At this time, the fixing cylinder 15 will be firmly fixed on the fixing seat 14. When the clamping plate 18 clamps the refining furnace cover and lifts it upward, the hook 42 on the side wall of the clamping plate 18 will hook onto the edge of the refining furnace cover, and the misaligned hook 42 will rotate on the fixing shaft 41 and retract into the groove 4.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
