Description

Technical Field

[0001] This invention relates to the field of energy-saving kilns, specifically to an energy-saving melting furnace device. Background Technology

[0002] Compared to traditional marble and granite, nanocrystalline slabs have numerous advantages: their compressive strength, flexural strength, and Mohs hardness are far superior to those of marble and granite; their acid and alkali resistance is also significantly higher. Microcrystalline slabs absorb almost no water, and their surface gloss surpasses that of marble and granite products. Furthermore, microcrystalline slabs have zero radioactivity, while other stone materials exhibit some degree of radioactivity, making them an environmentally friendly advantage.

[0003] The raw material mixture for nanocrystalline glass is fed into an oxy-fuel combustion furnace via a feeder, where it melts into a homogeneous, bubble-free molten glass at a high temperature of approximately 1500°C. However, even if the mixture is homogeneous during feeding, the density and melting rate of different raw materials vary. In the large furnace, heavy, refractory particles may sink, while light, fusible particles may float to the surface, easily forming "uneven composition" streaks or lumps. This can lead to streaks, stones, or inconsistent performance in the final product. Furthermore, the upper part of the furnace is directly heated by the flame, reaching extremely high temperatures (e.g., 1600°C), while the bottom and sides are cooler due to heat dissipation (e.g., 1400°C). This 200°C temperature difference is called the "temperature gradient." The viscosity (thickness) of the molten glass varies drastically at different temperatures. The cold molten glass at the bottom is very viscous, like maltose; the hot molten glass at the top is very thin, like water. This "thin upper layer, thick lower layer" state severely hinders the aforementioned convective mixing, making homogenization extremely difficult. Only by obtaining a pool of "perfect" molten glass—where the chemical composition and temperature are exactly the same at any time and from any place—can nanocrystalline plates of superior quality and consistent performance be produced after rolling and crystallization.

[0004] Currently, forced convection (such as mechanical stirring) is generally used for homogenization. To reduce the temperature gradient, bottom bubbling is generally used to enhance bottom disturbance, and electric auxiliary heating is used to accurately compensate for heat in order to minimize the temperature difference between the top and bottom and front and back.

[0005] However, mechanical stirring involves external equipment, which causes additional power consumption and the mechanical equipment needs to withstand higher temperatures, increasing the probability of damage. It also increases impurities in the molten glass. Reducing temperature differences through temperature compensation will increase power consumption and is not energy-efficient. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an energy-saving melting furnace device, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving melting furnace apparatus, comprising a feeding assembly, a primary mixing assembly, and a secondary mixing assembly connected in sequence, and further comprising a heat recovery assembly, which utilizes the heat of the melting furnace to perform secondary heating on the feeding assembly, the primary mixing assembly, and the secondary mixing assembly respectively; the feeding assembly includes two dispersing channels for dispersing the raw material mixture; the primary mixing assembly includes a vortex mixing mechanism, through which the dispersed raw material mixture is recombined; the secondary mixing assembly includes two sets of inclined channels, the ends of which converge to promote homogenization of the raw material solution.

[0008] Preferably, the heat recovery assembly includes an end refractory chamber enclosed outside the secondary mixing assembly; a middle refractory chamber enclosed outside the primary mixing assembly; and a front refractory chamber installed outside the feeding assembly. The end refractory chamber, the middle refractory chamber, and the front refractory chamber are interconnected, and the heat inside the furnace can pass through the end refractory chamber, the middle refractory chamber, and the front refractory chamber respectively to heat the secondary mixing assembly, the primary mixing assembly, and the feeding assembly.

[0009] Preferably, the primary mixing component further includes a dual-channel inclined feeder with an overall inverted V-shaped structure. The dual-channel inclined feeder is provided with a receiving port and a discharge port. The receiving port is located at the top of the middle position, and the discharge port is located at the bottom of both ends. The dual-channel inclined feeder includes two V-shaped flow channels, corresponding to two dispersing flow channels. The vortex mixing mechanism is provided in two sets, respectively located on both sides of the dual-channel inclined feeder. Two V-shaped flow channels on one side of the dual-channel inclined feeder are connected to one vortex mixing mechanism. Two staggered swirling pipes are installed on the vortex mixing mechanism. The swirling pipes are tangent to the vortex mixing mechanism, and the two swirling pipes are connected to the two V-shaped flow channels.

[0010] Preferably, the secondary mixing component further includes two sets of refractory boxes, which are respectively connected to the lower ends of two vortex mixing mechanisms. Inclined flow channels are installed in the refractory boxes, and the inclined flow channels in the two refractory boxes are arranged opposite to each other. It also includes a converging channel, which is fixedly installed at the bottom of the two sets of fire-resistant boxes. One end of the fire-resistant box is located at the bottom of the inclined channel and is equipped with a pouring port, which corresponds to the converging channel.

[0011] Preferably, the feeding assembly further includes a feeding trough, and both dispersing channels are fixed to one side of the feeding trough. The feeding trough is provided with two heat-insulating chambers, and the two heat-insulating chambers are respectively connected to the two dispersing channels. It also includes a distributor, with the other end of each of the two dispersing channels fixedly connected to the distributor. The distributor corresponds to the dual-channel inclined feeder, and the distributor connects the two dispersing channels to the two V-shaped channels of the dual-channel inclined feeder respectively.

[0012] Preferably, the heat recovery assembly includes a smoke collector connected to the melting furnace, and an ash baffle plate is installed inside the smoke collector; It also includes the main flue, one end of which is connected to the smoke collector and the other end is connected to the end refractory chamber.

[0013] Preferably, the heat recovery assembly further includes two sets of auxiliary flues, one end of which is connected to the smoke collector, and one end of each set of auxiliary flues passes through the end refractory chamber and is respectively connected to the two sets of refractory boxes.

[0014] Preferably, a portion of the front-end refractory chamber encloses two dispersing channels, while the remaining portion passes through the bottom of the feeding trough.

[0015] Preferably, it also includes a structural frame composed of refractory bricks, and the feeding assembly, primary mixing assembly, secondary mixing assembly and heat recovery assembly are all installed within the structural frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This energy-saving melting furnace device, by setting up a primary mixing component and a secondary mixing component, does not use external mechanical equipment. It only uses the flow of the melt to achieve swirling and convective mixing, which can promote the homogenization of raw material mixture. Raw materials of different weights gradually mix during the homogenization process. The mixing takes place inside, which saves the investment in mechanical equipment and avoids external contamination of the melt.

[0017] 2. This energy-saving melting furnace device, by setting up a heat recovery component, allows the flame and flue gas of the melting furnace to pass through the primary mixing component and the secondary mixing component respectively. During the homogenization of the raw material mixture, it continuously keeps it warm, preventing the raw materials from becoming lighter or heavier due to different cooling rates, thus avoiding the temperature gradient difference from continuing to increase. It does not require electric auxiliary heat compensation, which saves energy and realizes the secondary utilization of the heat of the flue gas in the melting furnace.

[0018] 3. In this energy-saving melting furnace, the heat in the furnace is not utilized from bottom to top. Some of the heat is directly delivered to the inclined flow channel, which can keep the melt warm by utilizing high heat during the inclined convection process. In this way, the raw materials of different viscous consistency in the melt that have been mixed in the early stage can be more uniformly mixed by convection under the heat preservation state, and the homogenization can be carried out more smoothly.

[0019] 4. This energy-saving melting furnace melting device, by setting two dispersed flow channels, can simultaneously pour melts at different liquid levels in the same furnace, or pour melts at different liquid levels in different furnaces, or directly divide the melt into two and pour them out. In the later stage, homogenization can be achieved by utilizing natural flow. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0024] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0025] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0026] like Figures 1-9 As shown, an energy-saving melting furnace apparatus includes a feeding assembly 1, a primary mixing assembly 2, and a secondary mixing assembly 3 connected in sequence, and a heat recovery assembly 4, which utilizes the heat from the melting furnace to perform secondary heating on the feeding assembly 1, the primary mixing assembly 2, and the secondary mixing assembly 3 respectively. The feeding assembly 1 includes two dispersing channels 101 for dispersing the raw material mixture. The primary mixing assembly 2 includes a vortex mixing mechanism 201, through which the dispersed raw material mixture is recombined. The secondary mixing assembly 3 includes two sets of inclined channels 301, which converge at their ends to promote homogenization of the raw material solution.

[0027] During the preparation of the nanocrystalline glass, the mixture is fed into an oxy-fuel combustion furnace via a feeder, where it melts into a uniform, bubble-free molten glass at a high temperature of approximately 1500°C. Oxy-fuel combustion technology effectively improves thermal efficiency, reduces emissions of nitrogen oxides and other waste gases, and is more energy-efficient and environmentally friendly. The molten glass undergoes a period of clarification and homogenization to remove bubbles and ensure uniform composition.

[0028] Different raw materials have different densities and melting rates, resulting in variations in local composition. The temperature distribution within the furnace is not entirely uniform, exhibiting temperature gradients, which leads to differences in the viscosity and fluidity of the molten glass in different areas. In this solution, the raw material mixture is first dispersed in the dispersion channel 101, then homogenized by swirling in the vortex mixing mechanism 201, and finally converged and convected in the inclined channel 301 to eliminate the microscopic inhomogeneities in chemical composition and temperature within the molten glass.

[0029] like Figures 4-5 As shown, in an optional embodiment, the heat recovery component 4 includes an end refractory chamber 401, which is enclosed outside the secondary mixing component 3; a middle refractory chamber 402, which is enclosed outside the primary mixing component 2; and a front refractory chamber 403, which is installed outside the feeding component 1. The end refractory chamber 401, the middle refractory chamber 402, and the front refractory chamber 403 are interconnected, and the heat inside the furnace can pass through the end refractory chamber 401, the middle refractory chamber 402, and the front refractory chamber 403 respectively to heat the secondary mixing component 3, the primary mixing component 2, and the feeding component 1.

[0030] In this embodiment, the end refractory chamber 401, the middle refractory chamber 402, and the front refractory chamber 403 are all enclosed, with their inner walls lined with refractory and heat-insulating materials (such as high-alumina refractory bricks or alumina hollow spherical bricks). These materials can withstand the long-term scouring of high-temperature flue gas and reduce heat loss to the outside, allowing most of the heat carried by the flue gas to be transferred to the molten glass in the flow channel, avoiding heat waste and reducing heat dissipation. This ensures that the heat carried by the high-temperature flue gas discharged from the furnace can be continuously transferred to the raw material mixture in the flow channel, preventing the raw material from rapidly decreasing in temperature during the flow homogenization process, reducing the temperature difference between different parts of the melt, and reducing convection resistance caused by viscosity differences. At the same time, the residual heat of the furnace flue gas is used for heat preservation, eliminating the need for additional electrical energy consumption for temperature compensation. This fully recovers the residual heat of the furnace flue gas, improves energy utilization, and meets the requirements of energy-saving design.

[0031] The front-end fire-resistant chamber 403 is externally connected to a later-stage smoke exhaust pipe or negative pressure ventilation equipment to ensure continuous heat transfer inside.

[0032] In an optional embodiment, the primary mixing component 2 further includes a dual-channel ramp feeder 202, which has an overall inverted V-shaped structure. The dual-channel ramp feeder 202 is provided with a receiving port and a discharging port. The receiving port is located at the top of the middle position, and the discharging port is located at the bottom of both ends. The dual-channel ramp feeder 202 includes two V-shaped flow channels 203, corresponding to two dispersing flow channels 101. Two sets of vortex mixing mechanisms 201 are provided, respectively located on both sides of the dual-channel ramp feeder 202. The two V-shaped flow channels 203 on one side of the dual-channel ramp feeder 202 are connected to one vortex mixing mechanism 201. Two vertically intersecting swirling pipes 204 are installed on the vortex mixing mechanism 201. The swirling pipes 204 are tangent to the vortex mixing mechanism 201, and the two swirling pipes 204 are connected to the two V-shaped flow channels 203.

[0033] In this embodiment, the flow channels and pipes in contact with the melt are made of high-temperature resistant materials that can transfer heat, such as dense alumina refractory material. This material itself does not introduce impurities and allows the heat from external flue gas to be smoothly transferred to the internal melt. Heat-conducting holes can also be opened in positions where the melt does not leak. The above materials need to withstand long-term corrosion at temperatures above 1400°C and will not produce additional impurities mixed into the molten glass during use. In addition, the high temperature in the refractory chamber will also transfer heat to the flow channels and pipes, maintaining the temperature of the melt inside the flow channels and preventing the melt from cooling down and thickening, which would affect the flow.

[0034] In an optional embodiment, the secondary mixing component 3 further includes two sets of refractory boxes 302, which are respectively connected to the lower ends of two vortex mixing mechanisms 201. Inclined flow channels 301 are installed in the refractory boxes 302, and the inclined flow channels 301 in the two refractory boxes 302 are arranged opposite to each other. It also includes a converging flow channel 303, which is fixedly installed at the bottom of the two sets of refractory boxes 302. One end of each refractory box 302, located at the lowest point of the inclined flow channel 301, is provided with a pouring port corresponding to the converging flow channel 303.

[0035] In this embodiment, the two sets of inclined channels 301 are oriented in opposite directions and are staggered. The melt left by the two channels will be heated a second time, and at the same time, it will be convectioned again in the converging channel 303 to achieve homogenization again. The converging channel 303 is an inverted cone structure. After the melt flows in, it will eventually converge downward and be discharged outward.

[0036] In an optional embodiment, the feeding assembly 1 further includes a feeding trough 102, with two dispersing channels 101 fixed to one side of the feeding trough 102. The feeding trough 102 is provided with two heat-insulating chambers 103, which are respectively connected to the two dispersing channels 101. It also includes a distributor 104, with the other end of each of the two dispersing channels 101 fixedly connected to the distributor 104. The distributor 104 corresponds to the dual-channel inclined feeder 202, and the distributor 104 connects the two dispersing channels 101 to the two V-shaped channels 203 of the dual-channel inclined feeder 202.

[0037] In this embodiment, the feeding trough 102 is used to pour the melt. After the melt flows out of the furnace outlet, it can directly enter the feeding trough 102. After being distributed by the distributor 104, it flows into the two dispersion channels 101 respectively. At the same time, the high-temperature flue gas in the front refractory chamber 403 will continuously keep the melt in the dispersion channel 101 warm through the heat preservation chamber 103, ensuring that the melt maintains a stable flow viscosity and will not have the problem of cooling and solidification during the dispersion stage, thus providing a stable basic condition for subsequent mixing and homogenization.

[0038] In an optional embodiment, the heat recovery assembly 4 includes a smoke collector 404 connected to the melting furnace, and an ash baffle 405 installed inside the smoke collector 404. It also includes a main flue 406, one end of which is connected to the smoke collector 404, and the other end of which is connected to the end refractory chamber 401.

[0039] In this embodiment, the smoke collector 404 is installed on the melting furnace to directly collect the high-temperature flue gas discharged from the furnace. The baffle plate 405 is made of porous refractory bricks and can intercept unburned solid particles and molten fly material carried in the flue gas, preventing these impurities from entering the subsequent flue and causing blockage. At the same time, the intercepted fly material still contains usable raw material components, which can be recycled by regular cleaning, preventing impurities from being mixed into the melt after heat exchange with the flue gas and affecting the purity of the product. After the flue gas enters the main flue 406, it first enters the end refractory chamber 401 at the very end to heat and maintain the temperature of the secondary mixing component 3, which has completed most of the homogenization. Then, it enters the middle refractory chamber 402 and the front refractory chamber 403 in sequence along the connecting structure, realizing the gradient utilization of heat from back to front, matching the flow direction of the melt from front to back, so that the melt is always in a suitable heat preservation temperature range throughout the homogenization process.

[0040] In an optional embodiment, the heat recovery assembly 4 further includes two sets of secondary flues 407, one end of which is connected to the smoke collector 404. One end of each set of secondary flues 407 passes through the end refractory chamber 401 and is connected to the two sets of refractory boxes 302 respectively.

[0041] In this embodiment, the secondary flue 407 is directly connected to the refractory box 302 to heat the inclined flow channel 301, ensuring that the melt in the inclined flow channel 301 can always maintain a sufficiently high temperature, reducing the melt viscosity, allowing melts of different densities to fully convect and mix, improving the final homogenization effect, and preventing the thin and thick raw materials from stratifying due to cooling in the inclined flow channel 301, thus failing to achieve sufficient convective homogenization.

[0042] In an alternative embodiment, a portion of the front refractory chamber 403 encloses two dispersive channels 101, while the remainder passes through the bottom of the discharge chute 102.

[0043] In this embodiment, the wrapped portion can heat the dispersion channel 101, while the flue gas passing through the bottom of the feeding trough 102 can keep the feeding trough 102 warm. To maintain the heat inside the kiln, the flue gas will not be completely leak-proof; some needs to be discharged to ensure stable internal pressure and prevent excessive pressure buildup that could affect production safety. After passing through the feeding trough 102, the flue gas is connected to a subsequent exhaust pipe. This exhaust pipe undergoes desulfurization and denitrification treatment before being discharged into the atmosphere, preventing the direct emission of harmful pollutants from the flue gas.

[0044] like Figures 1-3 As shown, in an optional embodiment, it also includes a structural frame 5 composed of refractory bricks, and the feeding assembly 1, the primary mixing assembly 2, the secondary mixing assembly 3 and the heat recovery assembly 4 are all installed in the structural frame 5.

[0045] In this embodiment, the structural frame 5 is used to support the entire equipment. The exterior is made of stacked blocks. After the construction is completed, a layer of refractory and heat-insulating mortar can be applied to the outer layer to further reduce heat loss to the environment and improve the overall heat insulation and energy-saving effect. At the same time, it is convenient to adjust the overall installation layout according to the size of the production site and the supporting melting furnace, making it more adaptable.

[0046] In use, the molten raw material mixture is first fed into the feeding tank 102. The raw material mixture flows into two dispersion channels 101 through two insulated chambers 103 in the feeding tank 102. After dispersion, it is conveyed to the two V-shaped channels 203 of the dual-channel inclined feeder 202 by the distributor 104. The raw material flows downward along the V-shaped channels 203 and enters the vortex mixing mechanism 201 on both sides tangentially through the corresponding upper and lower staggered swirling pipes 204. The raw material forms a swirling flow in the vortex mixing mechanism 201 and achieves preliminary mixing and recombination by generating vortex disturbances through its own flow, completing the primary homogenization. After primary homogenization, the melt flows out of the vortex mixing mechanism 201 and enters the inclined channels 301 in the refractory boxes 302 on both sides. It flows downward along the inclined channels 301 and finally merges into the converging channel 303 from the pouring port at the end of the inclined channels 301. The two sets of inclined channels 301 are arranged opposite each other. The molten material flowing out of the furnace undergoes collision and convection within the converging channel 303, further achieving component homogenization through its own flow. Throughout the process, the high-temperature flue gas generated by the furnace is collected by the smoke collector 404, and after the ash baffle 405 filters the ash and slag in the flue gas, most of the flue gas enters the end refractory chamber 401 along the main flue 406, and then flows sequentially from the middle refractory chamber 402 into the front refractory chamber 403, continuously insulating the secondary mixing component 3, the primary mixing component 2, and the feeding component 1. At the same time, some flue gas directly enters the interior of the refractory box 302 through the two sets of auxiliary flues 407, directly insulating the melt within the inclined channel 301, ensuring that the melt maintains a stable temperature during the convective homogenization process, avoiding the increase in melt viscosity due to temperature drop that hinders homogenization, and eliminating the need for additional electrical heating. This fully recovers and utilizes the waste heat of the furnace flue gas, achieving energy-saving goals while completing natural homogenization.
