Description

Technical Field

[0001] This utility model belongs to the field of submerged arc furnace technology, and in particular relates to a long-life submerged arc furnace. Background Technology

[0002] Submerged arc furnaces are key equipment in industries such as metallurgy and chemical engineering. Their exteriors are typically fitted with protective plates or sleeves for insulation and protection. These plates operate under harsh conditions of high temperature and high vibration for extended periods, making them prone to damage and requiring periodic replacement. Therefore, the ease and reliability of disassembling and assembling these protective plates directly impacts the equipment's maintenance efficiency, operating costs, and safety.

[0003] Chinese patent CN220321986U discloses a submerged arc furnace, aiming to solve the problem of difficult disassembly and assembly of protective sleeves. The patent includes a furnace body with several lower protective sleeves evenly distributed around its outer circumference. Adjacent lower protective sleeves are bonded together. An upper sleeve is also fitted over the outer side of the furnace body, with its bottom end detachably connected to the lower protective sleeves. An anti-scalding pad is provided at the top opening of the upper sleeve. The sleeves are disassembled and assembled by using an electromagnet to control the insertion rod and by separating the adhesive rough surface from the hook surface.

[0004] However, the aforementioned existing technologies have obvious drawbacks: First, the disassembly and assembly process still relies on manual operation, such as pulling out the plug and separating the bonding surfaces, which is inefficient and poses serious safety hazards when working near a high-temperature furnace. Second, the fixing method relies on electromagnet attraction and bonding, lacking an effective mechanical self-locking mechanism. Under the continuous thermal expansion and contraction and strong vibration conditions of the submerged arc furnace, it is very easy to loosen or even fall off, which not only affects the heat preservation effect but also poses a threat to safe production and limits the improvement of the overall lifespan of the equipment.

[0005] Therefore, there is an urgent need for a new type of submerged arc furnace structure that can achieve automated operation, reliable locking, and self-locking function to overcome the shortcomings of existing technologies. Utility Model Content

[0006] This invention provides a long-life submerged arc furnace, aiming to solve the problems of the current technology where the installation and removal of the sheath still relies on manual operation, which is inefficient and unsafe, and lacks an effective self-locking mechanism, making it prone to loosening due to vibration or thermal deformation.

[0017] Compared with related technologies, the long-life submerged arc furnace provided by this utility model has the following beneficial effects: I. This design adopts an electrically driven rotary locking and linkage mechanism to achieve rapid and automated disassembly and assembly: the forward and reverse motors drive the worm gear transmission, which drives the linkage component and the positioning component to achieve automatic clamping and release of the guard plate without manual intervention, thus improving disassembly and assembly efficiency and safety.

[0018] Second, the introduction of a worm gear self-locking mechanism to prevent loosening: By utilizing the self-locking characteristics of worm gear transmission, it is ensured that even if subjected to vibration or thermal stress after positioning, it is not easy to back out, thereby enhancing the stability and service life of the structure.

[0019] 3.

[0020] IV. The spring reset mechanism facilitates disassembly: A spring coil is set to provide elastic reset force when the positioning rod retracts, ensuring that it can quickly detach from the guard plate when the motor reverses, making it easy to replace individual guard plates and making maintenance more flexible.

[0024] A preferred embodiment of the long-life submerged arc furnace provided by this utility model is, for example... Figures 1 to 4 As shown: A long-life submerged arc furnace, comprising: 1. Submerged arc furnace body; The module assembly 2 is installed on the outside of the electric arc furnace body 1. The module assembly 2 includes a sleeve 21 fixedly connected to the outside of the electric arc furnace body 1, and a protective plate 22 assembled in a ring on the outside of the sleeve 21. A rotary locking assembly 3 is installed on the upper outer side of the electric arc furnace body 1; A rotating assembly 4 is located on the upper and lower sides of the outer side of the electric arc furnace body 1 and can rotate and lock synchronously with the rotating locking assembly 3; Positioning component 5 is located on the outside of the connecting component 4; The positioning component 5 includes a sleeve 51 and a positioning rod 52 arranged in a ring around the sleeve 51 and used to position the sleeve 21 in conjunction with the coupling component 4.

[0025] Rotary locking assembly 3 includes: Symmetrically and fixedly connected to the upper support frame 31 on the outside of the electric arc furnace body 1; The main shaft 33 is rotatably connected to the middle of the two sets of support frames 31; A forward and reverse motor 32 is fixedly connected to the outside of a set of support frames 31; The output end of the forward and reverse motor 32 is fixedly connected to the main rotating shaft 33.

[0026] The rotary locking assembly 3 also includes: The worm gear 331 is fixedly connected to the outside of the main shaft 33.

[0027] The connecting component 4 also includes: Rotary connection to coupling 41 on the outside of the electric arc furnace body 1; The worm gear 332 is fixedly connected to the upper outer side of the coupling 41; The worm gear 332 is in contact with the worm 331 and is in a meshing rotational connection; In this embodiment, the worm gear 331 and worm wheel 332 are driven by the forward and reverse motor 32 to mesh and transmit power, which achieves smooth and reliable power transmission. It is especially suitable for the harsh working conditions of high temperature and high vibration in electric arc furnaces. The self-locking characteristics of the worm gear and worm wheel effectively prevent the guard plate 22 from loosening due to vibration or thermal deformation during operation, which significantly improves the service life and safety of the equipment. The connecting component 4 also includes: Gear discs 411 are symmetrically and fixedly connected to the upper and lower sides of coupling 41.

[0028] The connecting component 4 also includes: Rotary connection to the ring seat 42 on the outside of the electric arc furnace body 1; The tooth groove group 421 is distributed in a ring on the outer side of the ring seat 42; The toothed groove assembly 421 is in contact with the toothed disc 411 and is in a meshing rotatable connection; Through the meshing transmission between the toothed disc 411 and the toothed groove group 421, the ring seat 42 and the extrusion plate 422 are driven to rotate synchronously, realizing the synchronous action of multiple positioning rods 52, ensuring that all guard plates 22 are evenly stressed and synchronously pressed, avoiding local stress concentration, and further enhancing the overall integrity and stability of the structure. The extrusion plate 422 is fixedly connected to the outside of the ring seat 42 in a ring shape.

[0029] Positioning component 5 also includes: An upslope 521 is formed at one end of the positioning rod 52; The upslope surface 521 corresponds to the position of the extrusion plate 422.

[0030] Positioning component 5 also includes: A downward slope 522 is formed at the other end of the positioning rod 52; The shape of the lower slope surface 522 matches the inner groove of the guard plate 22.

[0031] Positioning component 5 also includes: An inner connecting block 53 is fixedly connected in a ring shape inside the sleeve 51; A vertical rod 54 is slidably connected to the inner side of the inner connecting block 53; The vertical rod 54 and the positioning rod 52 are fixedly connected.

[0032] Positioning component 5 also includes: A spring coil 541 is fitted onto the outside of the vertical rod 54; One end of the spring coil 541 is in contact with the positioning rod 52, and the other end of the spring coil 541 is in contact with the inner connecting block 53. The upper slope 521 at one end of the positioning rod 52 cooperates with the extrusion plate 422, and the lower slope 522 at the other end matches the inner groove of the guard plate 22, making the pushing process smooth and the positioning accurate. Combined with the elastic reset function of the spring ring 541, the guard plate can be quickly disassembled and reliably fixed, which greatly improves maintenance efficiency and operation safety.

[0033] When it is necessary to complete the assembly of the guard plate 22 at the sleeve 21, the guard plates 22 can be first installed inside the sleeve 21. Then, the forward and reverse motor 32 is started. The forward and reverse motor 32 can drive the main shaft 33 and the worm gear 331 to rotate inside the two sets of support frames 31. At this time, under the meshing action of the worm gear 331 and the worm wheel 332, the coupling 41 located inside the worm wheel 332 will rotate synchronously, and the gear plate 411 located outside the coupling 41 will rotate synchronously with the coupling 41. At this time, under the meshing action of the gear plate 411 and the tooth groove group 421, the ring seat 42 located inside the tooth groove group 421 will rotate synchronously.

[0034] Specifically, the extrusion plate 422 located at the bottom of the ring seat 42 will rotate synchronously with the ring seat 42. At this time, the bottom of the extrusion plate 422 will gradually contact and press down on the positioning rod 52. When the positioning rod 52 is pushed by the lower slope surface 522, it will continue to slide until it is inserted into the groove on the side of the guard plate 22. The lower slope surface 522 at the bottom of the positioning rod 52 can push the guard plate 22 inward, thereby making the guard plate 22 tightly adhere to the body 1 of the electric arc furnace. Through this design, the positioning and fixing work of each guard plate 22 on the outside of the sleeve 21 can be completed quickly. In addition, the worm gear 331 and worm wheel 332 meshing self-locking design adopted in this design can effectively prevent loosening after positioning. Specifically, when the single guard plate 22 reaches the end of its service life, the forward and reverse motor 32 can be started to drive the main rotating shaft 33 and the worm gear 331 to reverse. At this time, the extrusion plate 422 will gradually disengage from the positioning rod 52, and the positioning rod 52 will also retract from the slot on the side of the guard plate 22 under the elastic reset action of the spring ring 541. At this time, the guard plate 22 can be quickly disassembled and assembled.
