Description

Technical Field

[0001] This utility model belongs to the field of metallurgical equipment technology, and in particular relates to an impact-resistant reinforcement structure for the furnace mouth of a silver separating furnace. Background Technology

[0002] Silver furnaces are key equipment used for refining silver and are widely used in the metallurgical field. For example, when processing precious lead, return slag precious lead, leaching slag precious lead, and crude silver powder, the oxidation and blowing process of silver furnaces is often used to remove various impurities, produce gold and silver alloy anode plates, and then electrolytically extract high-purity silver and gold.

[0003] However, traditional silver-separating furnaces often use straight cylindrical refractory bricks to build the furnace opening. When large pieces of material fall, they directly impact the inner wall of the furnace opening, causing the refractory material to crack and peel off. At the same time, the vibration generated by frequent feeding can easily cause the masonry structure to loosen. These problems ultimately lead to a short furnace opening life and require frequent furnace shutdowns for maintenance, which not only increases production costs but also affects production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an impact-resistant reinforcement structure for the furnace opening of a silver-separating furnace. Specifically, when large pieces of material enter the furnace opening, they first pass through an upper buffer layer of 45-degree inverted conical high-alumina silicon carbide bricks and embedded wear-resistant alloy mesh to initially disperse the impact energy. Then, they fall into a middle shock-resistant layer of magnesia-chrome bricks and stainless steel fiber-reinforced castable composite structure, where the elastic deformation of the castable absorbs vibration. The lower base layer, with its asphalt-impregnated ceramic fiber expansion joints, releases thermal stress. Simultaneously, multi-stage stepped protrusions cause the material to bounce and decelerate multiple times, and Y-shaped steel anchors are bifurcated. The end is embedded in the middle anti-vibration layer and fixed with high-temperature refractory adhesive. The buffer sleeve, spring and nut at its straight end work together to absorb vibration, greatly reducing the impact of material impact and feeding vibration on the furnace mouth, avoiding cracking and loosening of the masonry, extending the service life of the furnace mouth, reducing the number of shutdowns for maintenance, and ensuring the stable operation of the silver separating furnace. It solves the problem that the furnace mouth of traditional silver separating furnaces is mostly built with straight cylindrical refractory bricks. When large pieces of material fall, they will directly impact the inner wall of the furnace mouth, causing the refractory material to crack and peel off. At the same time, the vibration generated by frequent feeding can easily cause the masonry structure to loosen.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an impact-resistant reinforcement structure for the opening of a silver separating furnace, comprising a silver separating furnace with an opening extending through its top, the opening being fixedly connected to the furnace. It further includes: a reinforcement mechanism disposed on the opening, used to disperse the impact force on the opening when materials enter, and to improve the overall shock resistance of the opening; the reinforcement mechanism includes a protrusion fixedly connected to the inner wall of the silver separating furnace; and an interception mechanism disposed at the top of the opening, used to intercept oversized pieces of material accidentally mixed into the opening, reducing their direct impact on the opening; the interception mechanism includes a hopper fixedly connected to the top of the opening.

The buffer sleeves are located between the outer side of the silver separating furnace shell and the corresponding nut, and the inner diameter of the through hole opened at the end of the buffer sleeve away from the silver separating furnace is adapted to the outer diameter of the corresponding steel anchor.

[0009] Furthermore, the connecting assembly includes two connecting slots formed on the top of the hopper, and two connecting plates are fixedly connected to the intercepting plate. The bottoms of the two connecting plates extend into the corresponding connecting slots and are slidably connected to them. An installation slot is formed inside the hopper. The two connecting plates are fixedly connected to the intercepting plate by welding, and the intercepting plate is initially connected and quickly positioned by the cooperation of the two connecting plates and the two connecting slots. The two connecting slots and the two connecting plates are all designed to be rectangular, and the two connecting slots are adapted to the corresponding connecting plates.

[0010] Furthermore, the locking assembly includes two sliders slidably connected to the inner wall of the mounting groove. Each of the two sliders is fixedly connected to a connecting rod at the ends that are far apart from each other. Both connecting rods are fixedly connected to the corresponding sliders by welding. Both sliders are designed as right triangles, and the sides of the two sliders that are close to each other are the hypotenuses.

[0011] Furthermore, both connecting plates are provided with locking grooves, and locking blocks are fixedly connected to the ends of the two connecting rods that are far apart from each other.

[0013] This utility model has the following beneficial effects: 1. This utility model, through the setting of a reinforcement mechanism, specifically, when large pieces of material enter the furnace opening, first pass through the upper buffer layer of 45-degree inverted conical high-alumina silicon carbide bricks and embedded wear-resistant alloy mesh to initially disperse the impact energy, and then fall to the middle shock-resistant layer of magnesia-chrome bricks and stainless steel fiber-reinforced castable composite structure. The vibration is absorbed by the elastic deformation of the castable, and the thermal stress is released by the asphalt-impregnated ceramic fiber expansion joints in the lower base layer; at the same time, the multi-level stepped protrusions cause the material to bounce and decelerate multiple times, and the bifurcated ends of the Y-shaped steel anchors are embedded in the middle shock-resistant layer and fixed with high-temperature refractory adhesive. The buffer sleeve, spring, and nut at the straight end work together to absorb vibration, greatly reducing the impact of material impact and feeding vibration on the furnace opening, avoiding masonry cracking and loosening, extending the service life of the furnace opening, reducing the number of shutdowns for maintenance, and ensuring the stable operation of the silver separating furnace.

[0014] 2. This utility model incorporates an interception mechanism. Specifically, before the material enters the furnace opening, the hopper guides the material to fall in a concentrated manner, while the interception plate intercepts oversized pieces. During installation, the connecting plate and connecting groove cooperate to achieve initial positioning. Rotating the threaded rod clockwise pushes the second slider to press the first slider, causing the connecting rod to drive the locking block into the locking groove. The protrusion and groove cooperate for reinforcement, and the second spring stores force. During disassembly, reversing the threaded rod causes the second spring to push the first slider to reset, disengaging the locking block. This facilitates quick disassembly and maintenance, effectively reducing the impact of oversized materials on the furnace opening. Combined with the reinforcement mechanism, it enhances impact resistance, ensuring the safety and practicality of the silver separating furnace operation.

[0019] 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.

[0020] Please see Figure 1-8As shown, this utility model is an impact-resistant reinforcement structure for the opening of a silver separating furnace, including a silver separating furnace 1, with an opening 11 penetrating the top of the furnace 1 and fixedly connected to the furnace 1. It also includes: a reinforcement mechanism 2, which is disposed on the opening 11 and is used to disperse the impact force on the opening 11 when materials enter the opening and to improve the overall shock resistance of the opening 11. The reinforcement mechanism 2 includes a boss 21 fixedly connected to the inner wall of the silver separating furnace 1; and an interception mechanism 3, which is disposed on the top of the opening 11 and is used to intercept oversized pieces of material that accidentally enter the opening 11, reducing their impact on the opening 11. To prevent direct impact, the interception mechanism 3 includes a hopper 31 fixedly connected to the top of the furnace opening 11, with an interception plate 311 slidably connected to the inner wall of the hopper 31; the interception mechanism 3 also includes a connecting component 32, which is located on the top of the hopper 31 and is used to achieve a quick connection between the interception plate 311 and the hopper 31; and a locking component 33, which is located on the hopper 31 and is used to lock and fix the interception plate 311 on the hopper 31. Both the connecting component 32 and the locking component 33 are designed in two sets, and the two sets of connecting components 32 and locking components 33 are symmetrically arranged on the hopper 31.

[0021] Several steel anchors 22 penetrate the outer wall of the silver separating furnace 1. These steel anchors 22 are slidably connected to the furnace 1, and the side of each steel anchor 22 near the furnace opening 11 extends into the furnace opening 11 and is fixedly connected to it. When the forked ends of the several Y-shaped steel anchors 22 are inserted into the furnace opening 11, their forking angles are adapted to the layering direction of the alternating masonry of magnesia-chrome bricks and stainless steel fiber-reinforced castable in the middle of the furnace opening 11, allowing the forked ends to be embedded into masonry layers of different materials. In this process, the interlocking strength between the steel anchor 22 and the furnace mouth 11 masonry is further enhanced to prevent the steel anchor 22 from loosening under the impact or vibration of materials; a buffer sleeve 221 is slidably connected to the outer wall of several steel anchors 22, a spring 222 is sleeved on the outer wall of several steel anchors 22, and a nut 223 is threadedly connected to the outer wall of several steel anchors 22; the buffer sleeves 221, springs 222, and nuts 223 are all located at the straight ends of the corresponding steel anchors 22, and the several steel anchors 22 are all threadedly connected to the outer wall of several steel anchors 22. All straight ends of the anchors 22 are threaded, and several nuts 223 are threaded to the corresponding steel anchors 22 through the threads on the outer walls of the steel anchors 22. By setting up the reinforcement mechanism 2, specifically, when large pieces of material enter the furnace opening 11, the impact energy is initially dispersed by the upper buffer layer of 45-degree inverted conical high-alumina silicon carbide bricks and embedded wear-resistant alloy mesh, and then falls to the middle seismic-resistant layer of magnesia-chrome bricks and stainless steel fiber-reinforced castable composite structure. The vibration is absorbed through the elastic deformation of the castable. The lower base layer is impregnated with asphalt and ceramic fiber expansion joints to release thermal stress; at the same time, the multi-level stepped protrusions 21 cause the material to bounce and decelerate multiple times. The forked ends of the Y-shaped steel anchors 22 are embedded in the middle anti-vibration layer and fixed with high-temperature refractory adhesive. The buffer sleeves 221, springs 222 and nuts 223 at the straight ends work together to absorb vibration, greatly reducing the impact of material impact and feeding vibration on the furnace mouth 11, avoiding masonry cracking and loosening, extending the service life of the furnace mouth 11, reducing the number of shutdowns for maintenance, and ensuring the stable operation of the silver separating furnace 1.

[0022] The connecting assembly 32 includes two connecting slots 321 formed on the top of the hopper 31. Two connecting plates 322 are fixedly connected to the intercepting plate 311. The bottoms of the two connecting plates 322 extend into the corresponding connecting slots 321 and are slidably connected to the corresponding connecting slots 321. An installation slot 323 is formed inside the hopper 31. The locking assembly 33 includes two sliders 331 slidably connected to the inner wall of the installation slot 323. A connecting rod 332 is fixedly connected to the ends of the two sliders 331 that are far apart from each other. Each rod 332 is fixedly connected to its corresponding slider 331 by welding. Both connecting plates 322 have locking grooves 334. Locking blocks 335 are fixedly connected to the ends of the two connecting rods 332 that are furthest from each other. The ends of the two locking blocks 335 that are furthest from their respective connecting rods 332 pass through the corresponding connecting plates 322 and are slidably connected to the corresponding locking grooves 334. Springs 336 are fitted onto the outer walls of both connecting rods 332. One end of each spring 336 is fixedly connected to its corresponding slider 331. The other end is fixedly connected to the inner wall of the mounting groove 323; the inner wall of the mounting groove 323 is slidably connected to the slider 337; a threaded rod 338 passes through the right side of the hopper 31, and the threaded rod 338 is threadedly connected to the right side of the hopper 31; the left end of the threaded rod 338 is rotatably connected to the slider 337; by setting the interception mechanism 3, specifically before the material enters the furnace opening 11, the hopper 31 guides the material to fall in a concentrated manner, and the interception plate 311 intercepts oversized pieces of material; during installation, the connecting plate 322 cooperates with the connecting groove 321 to achieve initial... In step positioning, rotating the threaded rod 338 clockwise pushes the second slider 337 to press the first slider 331, causing the connecting rod 332 to drive the locking block 335 into the locking groove 334. The protrusion and groove cooperate to reinforce, and the second spring 336 stores force. When disassembling, reverse the threaded rod 338, and the second spring 336 pushes the first slider 331 to reset, causing the locking block 335 to disengage. This facilitates quick disassembly and maintenance, effectively reduces the impact of oversized materials on the furnace opening 11, and enhances the impact resistance in conjunction with the reinforcement mechanism 2, ensuring the safety and practicality of the silver separating furnace 1.

[0023] A specific application of this embodiment is as follows: When large pieces of material enter the silver separating furnace 1 from the top of the furnace opening 11, they first come into contact with the three-layer structure set from top to bottom of the furnace opening 11: the upper buffer layer uses 45-degree inverted conical high-alumina silicon carbide bricks, whose inverted conical structure can guide the material to slide down the slope, avoiding the material from vertically impacting the inner wall of the furnace opening 11. At the same time, the embedded wear-resistant alloy mesh can enhance the wear resistance of the buffer layer and initially disperse the impact energy of the material; then the material falls to the middle shock-resistant layer, which is an elastic-rigid composite structure formed by alternating masonry of magnesia-chrome bricks and stainless steel fiber-reinforced castables. The elastic deformation of the stainless steel fiber-reinforced castable absorbs the vibration energy generated by the impact of the material, while the magnesia-chrome bricks provide rigid support to prevent structural deformation of the masonry due to vibration. The material continues to fall to the lower foundation layer, where conventional refractory brick masonry serves as the foundation support for the furnace opening 11. Three-millimeter-thick asphalt-impregnated ceramic fiber expansion joints, spaced every 300 millimeters, effectively release the thermal stress generated at the furnace opening 11 under high-temperature conditions, preventing cracking of the foundation layer masonry due to thermal expansion and contraction. During this process, the multi-stage stepped protrusions 21 in the reinforcement mechanism 2 play a crucial role, ensuring proper material contact with the protrusions 21. After surface collision, the material bounces multiple times, gradually consuming its kinetic energy and significantly reducing its falling speed, thus further minimizing impact on the bottom of furnace opening 11 and the interior of silver separating furnace 1. Simultaneously, the Y-shaped steel anchor 22 penetrating the outer wall of silver separating furnace 1 has its forked ends embedded in the masonry layers of different materials in the middle of the shock-resistant layer of furnace opening 11. Combined with high-temperature refractory adhesive filling the gaps, this ensures a tight fit between the steel anchor 22 and the masonry of furnace opening 11. After the straight end of the steel anchor 22 passes through the pre-reserved through hole in the shell of silver separating furnace 1, the outer wall is slidably connected to the buffer sleeve 221, the sleeved spring 222, and the threaded connection. Nut 223 works in concert. When the silver dispensing furnace 1 vibrates due to feeding, spring 222 can absorb vibration energy through elastic deformation. Buffer sleeve 221 prevents direct friction between spring 222 and nut 223. The sliding connection characteristics of steel anchor 22, combined with the elasticity of spring 222, can effectively weaken the impact of vibration on the furnace opening 11 masonry and prevent the masonry from loosening. Through the above-mentioned working process of reinforcement mechanism 2, the impact force of materials can be dispersed, the overall shock resistance of furnace opening 11 can be improved, the service life of furnace opening 11 can be extended, and the number of furnace shutdowns for maintenance due to damage to furnace opening 11 can be reduced.

[0024] Before the material enters the furnace opening 11, the hopper 31 serves as a transition structure for the material entering the furnace opening 11. It guides the material to enter the furnace opening 11 in a concentrated manner, preventing the material from scattering to the edge of the furnace opening 11 and causing localized impact. The interceptor plate 311 intercepts any oversized pieces of material that may accidentally enter, preventing them from directly entering the interior of the furnace opening 11 and reducing their severe impact on the three layers of masonry and the boss 21 of the furnace opening 11. When installing the interceptor plate 311, first align the two rectangular connecting plates 322 on the interceptor plate 311 with the two corresponding rectangular connecting slots 321 opened at the top of the hopper 31, and slowly push the interceptor plate 311 so that the bottom of the connecting plate 322 slides along the inner wall of the connecting slot 321 to the bottom of the slot, quickly completing the interception process. After the initial connection and precise positioning of 311 and hopper 31, the operator rotates the threaded rod 338 clockwise. Since the threaded rod 338 is threadedly connected to the right side of hopper 31, it will advance into hopper 31 during rotation, simultaneously pushing slider 2 337 horizontally within mounting groove 323. This exerts a lateral thrust on slider 1 331, causing the two sliders 1 331 to move away from each other along the inner wall of mounting groove 323. Simultaneously, the limiting block on the rear side of slider 1 331 slides along the limiting groove on the rear side of mounting groove 323, ensuring that slider 1 331 only moves horizontally. The movement of slider 1 331 will cause the connecting rod 332 to move synchronously, compressing spring 2 336. Utilizing elastic potential energy, the connecting rod 332 drives the locking block 335 through the connecting plate 322 and into the locking groove 334 opened on the connecting plate 322. At this time, several protrusions on the outer wall of the locking block 335 will engage with several grooves on the inner wall of the locking groove 334, further enhancing the connection stability between the locking block 335 and the locking groove 334, thereby completing the complete locking and fixing of the intercepting plate 311 on the hopper 31, ensuring that the intercepting plate 311 will not shift when intercepting oversized materials. When it is necessary to disassemble the intercepting plate 311, the operator rotates the threaded rod 338 counterclockwise, and the threaded rod 338 retracts out of the hopper 31, causing the slider 337 to slide in the opposite direction in the mounting groove 323. The squeezing effect of slider 2 337 on the two sliders 1 331 is reduced; at this time, the elastic potential energy stored in the two springs 2 336 is released and pushes the two sliders 1 337 closer to each other. Sliding slider 1 331 drives the connecting rod 332 to move synchronously, so that the locking block 335 disengages from the locking groove 334 and retracts into the mounting groove 323. Then, the intercepting plate 311 can be grabbed and pulled upward, so that the connecting plate 322 slides out along the connecting groove 321, completing the disassembly of the intercepting plate 311. This simplifies the installation and disassembly operation of the intercepting plate 311, facilitates subsequent maintenance, ensures the continuous and stable operation of the intercepting mechanism 3, and further enhances the impact resistance of the furnace opening 11 in conjunction with the reinforcement mechanism 2, ensuring the stable operation of the silver separating furnace 1.
