Description

Technical Field

[0001] This invention relates to the field of metal processing technology, specifically to a metal smelting furnace with a quick-change furnace lining structure. Background Technology

[0002] A metal smelting furnace is a device that melts metals or alloys at high temperatures and keeps them in a liquid state. Its core function is to provide a stable and controllable high-temperature heat source and a good heat conduction / insulation structure to achieve efficient melting, uniform liquid formation, and facilitate subsequent refining or casting. Depending on the heat source and heat transfer method, furnaces can be configured with different features such as direct / indirect heating, external heat sources mainly based on radiation / convection, and whether or not an inert protective atmosphere is used, in order to meet the requirements of different metals, production capacity, and purity.

[0003] Patent publication number CN115307440A discloses an accelerated smelting device for non-ferrous metal smelting. This invention provides an accelerated smelting device for non-ferrous metal smelting with high smelting efficiency. The device includes a support frame, a smelting furnace, a baffle plate, a decomposition mechanism, and a sieving mechanism. The smelting furnace is mounted on the upper part of the support frame, and the baffle plate is clamped to the lower part of the furnace. The upper part of the furnace is equipped with a decomposition mechanism for crushing the non-ferrous metal, and the decomposition mechanism is equipped with a sieving mechanism for screening the non-ferrous metal. A cutting wheel crushes the non-ferrous metal, which is then sieved through the sieve plate. Non-ferrous metal of relatively uniform size falls downwards into the smelting furnace for smelting, thus accelerating the smelting process.

[0004] In metal smelting furnaces, the viscosity, density, and composition of the melt fluctuate continuously with temperature and time, resulting in an uneven temperature field. Local hot spots may overheat due to poor heat transfer efficiency, uneven heat source distribution, or unstable heat input such as combustion / electric arc, leading to secondary oxidation, inclusion aggregation, or the formation of metallurgical reaction byproducts. Furthermore, in actual use, the inability to quickly replace the furnace lining presents a drawback. During the operation of metal smelting furnaces, under the combined effects of high temperature, thermal cycling, chemical corrosion, and wear, the furnace lining may crack, peel, experience thermal fatigue, and refractory brick failure, leading to increased heat loss, localized overheating, and even slag metal leakage. Lining failure is often the direct trigger for furnace shutdown. If the furnace lining cannot be replaced quickly, a shutdown is inevitable. Conventional furnace lining replacement requires a long downtime, directly reducing production line availability and affecting delivery and production plans. Therefore, this invention is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a metal smelting furnace with a quick-change furnace lining structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal smelting furnace with a quick-change furnace lining structure, comprising a processing furnace and a heat-conducting mechanism installed inside the processing furnace. The processing furnace is equipped with a conveying mechanism for conveying and regulating a medium to the heat-conducting mechanism. The conveying mechanism, in conjunction with the heat-conducting mechanism, conveys the regulating medium to regulate the temperature field within the processing furnace. A bottom block is installed at the bottom of the processing furnace, and the heat-conducting mechanism is located on the bottom block. A connecting ring is installed at the top of the processing furnace via a pad block. A pretreatment mechanism for pretreating metal materials is installed on the top of the connecting ring. Both ends of the connecting ring are equipped with… The system includes a vertical frame with an adjustment mechanism for adjusting the position of the bottom block and the processing furnace. The adjustment mechanism facilitates material feeding and furnace lining replacement. The conveying mechanism is equipped with a purification mechanism for auxiliary purification of the regulating medium. The pretreatment mechanism is equipped with an auxiliary mechanism for controlling feeding and pretreatment. The heat conduction mechanism includes several inner lining blocks mounted on the bottom block via connecting components. The inner lining blocks are hollow, with their side walls fitting against the inner wall of the processing furnace and their bottom walls fitting against the top outer wall of the bottom block. A partition is installed in the middle of the inner wall of each inner lining block to separate the internal space of the inner lining block.

[0007] Furthermore, the pretreatment mechanism includes a top plate mounted on the top outer wall of the connecting ring. Gears and a gear ring are respectively mounted on the top outer wall of the top plate. The gear ring is located in the middle of the top plate. A feed groove is opened on the top outer wall of the top plate at the middle of the gear ring. The gear meshes with the gear ring. A dual-head drive motor is mounted on the top plate. One of the output shafts of the dual-head drive motor is fixedly connected to the gear. A filter plate is mounted on the inner wall of the connecting ring. Several ear plates are mounted on the inner wall of the gear ring. Vertical rods are mounted on the ear plates. Several crushing rods are mounted on the vertical rods.

[0008] Furthermore, the auxiliary mechanism includes a vertical column mounted on another output shaft of the dual-head drive motor, a first electric push rod embedded in the vertical column, a slotted block mounted on one end of the piston rod of the first electric push rod, a fixed block mounted on the outer wall of the processing furnace, a rotating block mounted on the fixed block, a baffle plate located between the processing furnace and the connecting ring mounted on the rotating block, and a slot corresponding to the slotted block opened on the top outer wall of the rotating block.

[0009] Furthermore, the adjustment mechanism includes a first connecting plate installed at both ends of the outer wall of the processing furnace, and a second connecting plate installed at both ends of the outer wall of the bottom block. Side grooves are opened on the outer walls of the first and second connecting plates. Slide rails are installed on the inner wall of the vertical frame. A slider is slidably installed on the slide rail. A rotary motor is embedded in the slider. A second electric push rod is installed at one end of the output shaft of the rotary motor. A plug corresponding to the side groove is installed at one end of the piston rod of the second electric push rod.

[0010] Furthermore, the conveying mechanism includes a connecting pipe installed between the bottom outer wall of the base block and the purification mechanism, a column installed on the top outer wall of the base block, the connecting pipe inserted into the column, a gas box installed on the outer wall of the treatment furnace, a conduit connected to the purification mechanism installed on the gas box, several gas pipes inserted into the inner lining block installed at the bottom of the gas box, and several nozzles installed on one side of the inner wall of the gas box.

[0011] Furthermore, the purification mechanism includes a hollow purification column installed between the connecting pipe and the conduit. A vertical ring is installed between the top inner wall and the bottom inner wall of the purification column. Several copper pillars are installed on the outer wall of the vertical ring. Blocks are installed at both ends of the bottom of the inner wall of the vertical ring. Several purification plates are placed on the top of the blocks. A connecting column is installed in the middle of the several purification plates.

[0012] Furthermore, the connecting assembly includes several limiting grooves opened on the outer wall of the column, a limiting block installed on the outer wall of the inner liner block that contacts the column and is inserted into the limiting groove, a connecting pipe embedded in the limiting block, and several pipe grooves opened on the outer wall of the connecting pipe located in the column, the connecting pipe being inserted into the pipe grooves.

[0013] Furthermore, a heating source is embedded in the inner wall of the processing furnace and the bottom block. The heating source is a high-temperature radiation source. The regulating medium includes either a gaseous medium or a liquid medium. The gaseous medium is a protective gas, and the liquid medium is a hot fluid.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This metal smelting furnace with a quick-change lining structure provides adjustable heat conduction through a heat-conducting mechanism. The regulating medium is delivered to this mechanism inside the furnace via a conveying system. This mechanism adjusts the heat conduction effect, thereby regulating the internal temperature field of the furnace. This ensures stable smelting during metal melting, reducing the probability of secondary oxidation, inclusion aggregation, or the formation of metallurgical reaction byproducts, thus improving smelting efficiency. Simultaneously, the adjustable mechanism facilitates the rapid removal of the lining blocks from the furnace for quick replacement. Since the lining (furnace lining) consists of several blocks, it allows for individual replacement of damaged blocks, improving lining block utilization and reducing operating costs. The replacement process is simple and convenient, reducing furnace downtime for lining replacement, increasing production line availability, and minimizing disruptions to delivery and production schedules.

[0016] Meanwhile, the pre-treatment mechanism can perform crushing and pre-treatment on the metal to improve the efficiency of subsequent metal smelting. The auxiliary mechanism can control the feeding and provide a closed effect during metal smelting. The purification mechanism can purify the regulating medium transported and recovered by the conveying mechanism to improve the service life of the regulating medium. The nozzles on the gas box can deliver the gases required for smelting to the processing furnace. Several of the nozzles can be replaced with suction heads to extract the gas from the processing furnace, so as to perform corresponding operations according to actual use needs.

[0017] Meanwhile, the position of the inner lining blocks can be restricted by the setting of the limiting groove and the limiting block. The column can be installed on the bottom block by magnetic attraction. At this time, when the position of the adjustment furnace is lowered to the point where the inner lining blocks are fully exposed, the inner lining blocks can be lifted up to remove all the inner lining blocks and the column. When the position of the adjustment bottom block is lowered to the point where the inner lining blocks are fully exposed, the inner lining blocks can be pulled outward to remove one or more inner lining blocks in different positions. This facilitates quick disassembly and assembly under different conditions and improves replacement efficiency. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0029] Metal smelting furnaces with quick-change lining structures are a type of equipment based on traditional smelting furnaces. They achieve lining replacement within a very short time during furnace downtime through modular linings, rapid connection and alignment, and controllable disassembly and assembly. The core idea is to divide the furnace lining into several independent high-temperature resistant modules. These modules are designed with quick locking and positioning to enable rapid disassembly and reinstallation, reducing personnel exposure to high temperatures, shortening downtime, and improving production continuity and safety. This structure requires comprehensive optimization in material selection, the high-temperature and corrosion resistance of connectors, thermal fatigue control, and maintaining alignment accuracy after lining replacement. Application scenarios include the smelting and refining processes of metals such as steel, aluminum, and copper, and it is particularly suitable for production lines with high lining wear, requiring frequent maintenance, or where shorter downtime is desired.

[0030] like Figures 1-9As shown, the present invention provides a technical solution: a metal smelting furnace with a quick-change furnace lining structure, including a processing furnace 1 and a heat-conducting mechanism 10 installed inside the processing furnace 1. A conveying mechanism 8 is installed on the processing furnace 1 for conveying and regulating the medium to the heat-conducting mechanism 10. The conveying mechanism 8 conveys the regulating medium in conjunction with the heat-conducting mechanism 10 to regulate the temperature field in the processing furnace 1. A bottom block 9 is installed at the bottom of the processing furnace 1, and the heat-conducting mechanism 10 is located on the bottom block 9. A connecting ring 2 is installed on the top of the processing furnace 1 via a pad. A pretreatment mechanism 3 for pretreating metal materials is installed on the top of the connecting ring 2. Vertical frames 5 are installed at both ends of the connecting ring 2, and adjustment mechanisms are installed on the vertical frames 5. The adjustment mechanism 4 for the position of the bottom block 9 and the processing furnace 1 completes the feeding and furnace lining replacement operations. The conveying mechanism 8 is equipped with a purification mechanism 7 for auxiliary purification of the adjustment medium. The pretreatment mechanism 3 is equipped with an auxiliary mechanism 6 for controlling the feeding and pretreatment. The heat conduction mechanism 10 includes several inner lining blocks 1001 installed on the bottom block 9 through connecting components. The interior of the inner lining block 1001 is a hollow structure. The side wall of the inner lining block 1001 is in contact with the inner wall of the processing furnace 1, and the bottom wall of the inner lining block 1001 is in contact with the top outer wall of the bottom block 9. A partition 1002 is installed in the middle of the inner wall of the inner lining block 1001 to separate the internal space of the inner lining block 1001.

[0031] It is important to note that when metal smelting is required, the metal to be smelted is first placed in the pretreatment mechanism 3. The pretreatment mechanism 3 performs crushing pretreatment on the metal to improve subsequent smelting efficiency. The heat conduction mechanism 10 adjusts the heat conduction performance. The conveying mechanism 8 delivers the adjusting medium to the heat conduction mechanism 10 located inside the processing furnace 1. The heat conduction mechanism 10 adjusts the heat conduction effect, thereby regulating the temperature field inside the processing furnace 1. This ensures stable smelting during metal smelting, reducing the probability of secondary oxidation, inclusion aggregation, or the formation of metallurgical reaction byproducts, thus improving smelting efficiency. Simultaneously, the adjusting mechanism 4 facilitates the rapid removal of the lining block 1001 from the processing furnace 1, thereby enabling... The inner lining block 1001 can be quickly replaced. The inner lining (furnace lining) is composed of several inner lining blocks 1001, which allows staff to replace individual damaged inner lining blocks 1001 individually. This improves the efficiency of the inner lining block 1001 and reduces the cost of use. The replacement process is simple and convenient, reducing the long downtime required for furnace lining replacement, increasing production line availability, and minimizing impact on delivery and production plans. The auxiliary mechanism 6 can control the feeding and provide a closed effect during metal smelting. The purification mechanism 7 can purify the regulating medium transported and recovered by the conveying mechanism 8 to improve the service life of the regulating medium. Temperature sensors can be installed on the inner wall of the inner lining block 1001 and inside the processing furnace 1 to accurately adjust the temperature field inside the processing furnace 1. The specific temperature sensors need to be suitable for the application scenario of metal smelting.

[0032] like Figure 4 As shown, the pretreatment mechanism 3 includes a top plate 301 installed on the top outer wall of the connecting ring 2. A gear 302 and a gear ring 303 are respectively installed on the top outer wall of the top plate 301. The gear ring 303 is located in the middle of the top plate 301. A feed groove is opened on the top outer wall of the top plate 301 at the middle of the gear ring 303. The gear 302 meshes with the gear ring 303. A dual-head drive motor is installed on the top plate 301. One of the output shafts of the dual-head drive motor is fixedly connected to the gear 302. A filter plate 307 is installed on the inner wall of the connecting ring 2. Several ear plates 304 are installed on the inner wall of the gear ring 303. Vertical rods 306 are installed on the ear plates 304. Several crushing rods 305 are installed on the vertical rods 306.

[0033] It should be noted that starting the dual-head drive motor drives one of the output shafts to rotate, which in turn drives the gear 302 to rotate. The gear 302 meshes with the gear ring 303, which in turn drives the gear ring 303 to rotate. The rotation of the gear ring 303 drives several ear plates 304, the vertical rods 306 on the ear plates 304, and the crushing rod 305 to rotate, thereby completing the crushing pretreatment of the metal to be melted. When the metal to be melted needs to be fed, it can be fed into the feed chute. The crushed metal can be filtered through the filter plate 307 to ensure the pretreatment effect of the metal. The specific size of the holes in the filter plate 307 is determined according to the actual use.

[0034] like Figure 4 As shown, the auxiliary mechanism 6 includes a vertical column 601 mounted on another output shaft of the dual-head drive motor. A first electric push rod is embedded in the vertical column 601. A slot block 602 is mounted on one end of the piston rod of the first electric push rod. A fixed block 604 is mounted on the outer wall of the processing furnace 1. A rotating block 603 is mounted on the fixed block 604. A baffle plate 605 located between the processing furnace 1 and the connecting ring 2 is mounted on the rotating block 603. A slot corresponding to the slot block 602 is opened on the top outer wall of the rotating block 603.

[0035] It should be noted that when auxiliary mechanism 6 is required, the first electric push rod is activated to insert the slot block 602 into the slot. At this time, the dual-head drive motor is activated to drive the other output shaft to rotate, which can drive the rotating block 603 and the baffle plate 605 to rotate, thereby completing the sealing and unsealing of the processing furnace 1 and improving the metal smelting effect.

[0036] like Figures 2-3 As shown, the adjustment mechanism 4 includes a first connecting plate 401 installed at both ends of the outer wall of the processing furnace 1, and a second connecting plate 402 installed at both ends of the outer wall of the bottom block 9. Side grooves are provided on the outer walls of the first connecting plate 401 and the second connecting plate 402. Slide rails 403 are installed on the inner wall of the vertical frame 5. A slider 404 is slidably installed on the slide rail 403. A rotary motor is embedded in the slider 404. A second electric push rod is installed at one end of the output shaft of the rotary motor. An insert block 405 corresponding to the side groove is installed at one end of the piston rod of the second electric push rod.

[0037] It should be noted that the adjusting mechanism 4 can be used to complete the feeding of molten metal and the replacement of the inner lining block 1001 in two different ways. The electric slide table component is composed of the slide rail 403 and the slider 404. When the adjusting mechanism 4 is needed, the slider 404 is adjusted by the slide rail 403 in conjunction with the slider 404 until the insert block 405 corresponds to the part to be adjusted. When the entire processing furnace 1 needs to be adjusted, the insert block 405 is adjusted to correspond to the side groove on the first connecting plate 401. When the bottom block 9 needs to be adjusted, the insert block 405 is adjusted to correspond to the side groove on the second connecting plate 402. After the correspondence is completed, the second electric push rod is activated to insert the insert block 405 into the side groove. Then, by starting the rotary motor, the angle of the processing furnace 1 and the bottom block 9 can be rotated to complete the feeding of the molten metal. The connection between the bottom block 9 and the processing furnace 1 can be made by electromagnet adsorption, or a U-shaped block can be used to make a block groove on the bottom block 9 and the processing furnace 1 for strong connection.

[0038] like Figures 4-6 As shown, the conveying mechanism 8 includes a connecting pipe 801 installed between the bottom outer wall of the base block 9 and the purification mechanism 7. A column 806 is installed on the top outer wall of the base block 9, and the connecting pipe 801 is inserted into the column 806. An air box 802 is installed on the outer wall of the treatment furnace 1. A conduit 803 connected to the purification mechanism 7 is installed on the air box 802. Several air pipes 805 inserted into the inner liner block 1001 are installed at the bottom of the air box 802. Several nozzles 804 are installed on one side of the inner wall of the air box 802.

[0039] It should be noted that a jacking pipe is installed on the gas box 802 to receive the regulating medium to be added. When the conveying mechanism 8 is required, the regulating medium is received through the gas box 802 and introduced into the inner liner block 1001 through the gas pipe 805. A guide pump is installed on the connecting pipe 801. The guide pump guides the regulating medium through the inner liner block 1001 and the connecting pipe 801 into the purification mechanism 7 for purification to form a flow loop. The guide pump corresponds to the regulating medium. At the same time, the gas required for smelting can be delivered to the processing furnace 1 through the nozzles 804 on the gas box 802. Several of the nozzles 804 can be replaced with suction heads to extract the gas from the processing furnace 1, so as to perform corresponding operations according to actual usage requirements.

[0040] like Figure 7 As shown, the purification mechanism 7 includes a hollow purification column 701 installed between the connecting pipe 801 and the conduit 803. A vertical ring 702 is installed between the top inner wall and the bottom inner wall of the purification column 701. Several copper columns 703 are installed on the outer wall of the vertical ring 702. Baffles 706 are installed at both ends of the bottom of the inner wall of the vertical ring 702. Several purification plates 705 are placed on the top of the baffles 706. A connecting column 704 is installed in the middle of the several purification plates 705.

[0041] It should be noted that the purification column 701 is a detachable structure and can be installed in the connecting ring 2 or the treatment furnace 1 by magnetic attraction. The connecting pipe 801 is a flexible hose to facilitate the position adjustment of the adjustment mechanism 4. The purification column 701 is equipped with a liquid inlet pipe and contains coolant. The coolant cools the conditioning medium passing through the purification column 701. At the same time, the conditioning medium can be filtered and purified by several purification plates 705. The specific material of the purification plates 705 is determined according to the actual use. Activated carbon plates are usually selected. The connecting column 704 and the stop block 706 allow several purification plates 705 to be removed at once for cleaning and replacement.

[0042] like Figure 9 As shown, the connecting assembly includes several limiting grooves 1005 formed on the outer wall of the column 806. A limiting block 1003 is installed on the outer wall of the inner liner block 1001 that contacts the column 806 and is inserted into the limiting groove 1005. A connecting pipe 1004 is embedded in the limiting block 1003. Several pipe grooves are formed on the outer wall of the connecting pipe 801 in the column 806, and the connecting pipe 1004 is inserted into the pipe grooves.

[0043] It should be noted that the position of the inner lining block 1001 can be restricted by the setting limit groove 1005 in conjunction with the limit block 1003. The column 806 can be installed on the bottom block 9 by magnetic attraction. At this time, when the position of the adjustment furnace 1 is lowered to the point where the inner lining block 1001 is completely exposed, the inner lining block 1001 can be lifted upward to remove all the inner lining blocks 1001 and the column 806. When the position of the adjustment bottom block 9 is lowered to the point where the inner lining block 1001 is completely exposed, the inner lining block 1001 can be pulled outward to remove one or more inner lining blocks 1001 in different positions, so as to facilitate quick disassembly and assembly under different conditions and improve replacement efficiency.

[0044] like Figure 1 As shown, a heating source is embedded in the inner wall of the processing furnace 1 and the bottom block 9. The heating source is a high-temperature radiation source. The regulating medium includes either a gaseous medium or a liquid medium. The gaseous medium is a protective gas, and the liquid medium is a hot fluid.

[0045] It is important to note that the specific components of the high-temperature radiation source are determined based on actual usage. The specific component arrangement can employ a multi-zone heating method for more precise temperature control. The exact arrangement and components are determined according to actual application. When introducing protective gas, the flow rate and inlet pressure need to be controlled to create stable thin-layer convection in localized areas. The effects include improving the uniformity of the local thermal field, suppressing overheating hotspots, and improving the temperature distribution on the furnace wall surface. Attention must be paid to the purity of the gas supply, the sealing of the inlet / outlet, the assessment of interference with the radiation field, and the impact of gas flow on the furnace atmosphere. The liquid medium introduction tank injects a controlled amount of hot fluid (with the boiling point, heat capacity, and chemical properties of the liquid clearly defined). Heat is carried away or introduced through evaporation / convection, and heat buffering is achieved through latent heat of phase change, improving temperature distribution and rapid response. Attention must be paid to the chemical stability of the liquid, its corrosiveness to the furnace wall materials, leakage risk, vapor pressure management, and whether it will contaminate the furnace atmosphere. In actual use, a suitable regulating medium needs to be selected based on the specific application to achieve temperature regulation of the temperature field without hindering normal smelting operations.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended embodiments and their equivalents.
