Description

Technical Field

[0001] This invention relates to the field of glass melting furnace feeding technology, specifically to an energy-saving glass melting furnace equipment. Background Technology

[0002] A glass melting furnace is a thermal equipment used in glass manufacturing to melt glass materials. It melts and clarifies powdered materials and added crushed glass according to the glass composition at high temperatures in the furnace to form molten glass that meets the forming requirements.

[0003] The existing glass melting furnace feeding equipment has the following shortcomings during use: Firstly, heat loss from the feeding port is severe. The feeding port is one of the largest heat loss channels in the melting furnace. Existing feeding equipment lacks effective shielding measures during the feeding interval. The high-temperature radiation inside the melting furnace continues to spread outward, while cold air from the outside is simultaneously injected into the furnace through the feeding port, causing temperature fluctuations inside the furnace and disrupting the stability of the melting furnace's thermal regime.

[0004] Secondly, the induction of materials into the furnace at room temperature exacerbates the fluctuation of heat load. In existing feeding equipment, materials are usually directly fed into the glass melting furnace cavity at room temperature. The huge temperature difference causes the temperature of the glass melt in the feeding area to drop sharply and the viscosity to increase. The clarification and homogenization processes are disturbed, and the thermal regime is forced to be adjusted frequently. Moreover, the preheating device is mostly an independent auxiliary device with a complex structure, and the preheated material suffers secondary heat loss during the transfer process.

[0005] Third, most existing equipment uses a continuous feeding method, where materials accumulate continuously in the kiln, with new material constantly covering unmelted material, resulting in insufficient heating and incomplete melting of the lower layer of material.

[0006] Therefore, developing a glass melting furnace feeding device that can shield the feeding port during the feeding interval, preheat the material with hot flue gas, realize intermittent feeding, and avoid material retention and rigid collision is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0018] This invention provides an energy-saving glass melting furnace. It has the following beneficial effects: 1. By setting up the feeding components, the feed inlet is shielded for most of the working cycle during the opening and closing of the two flame baffles, reducing the heat loss from the inside of the furnace shell to the outside, shortening the time and radiation window of the high temperature radiation inside the furnace shell to diffuse outward, and opening the feed inlet only for a short period of time during material feeding to meet the material conveying needs. At the same time, it provides sufficient residence time for the subsequent preheating components, ensuring that the material receives sufficient heat exchange in front of the furnace shell. It also avoids the unfavorable working condition of new material constantly covering unmelted material due to continuous feeding, thereby improving melting efficiency. 2. By setting up the preheating component, the material is preheated before being sent into the furnace shell, which reduces the heat required to heat up to the molten state and speeds up the melting reaction process. This helps to maintain the stability of the furnace's thermal state and allows the hot flue gas that was originally lost at the feed inlet to be captured again and used to preheat the material to be fed, thus converting the lost heat into effective heat. 3. Through the setting of the striking component, multiple second sliding rods continuously strike the bottom of the inclined conveyor plate under the drive of the side U-shaped frame wave structure, preventing the material from being stuck on the inclined surface of the inclined conveyor plate. As the material slides down the inclined surface, the continuous striking vibration breaks the adhesion between the material and the surface of the inclined conveyor plate, allowing the material to slide smoothly onto the upper surface of the flame deflector plate, and preventing the material from adhering to the surface of the finned heat exchange tube. The finned heat exchange tube is fixedly connected to the inclined conveyor plate through penetration. The striking vibration is transmitted to the finned heat exchange tube through the inclined conveyor plate, shaking off the material adhering to the surface of the finned heat exchange tube, ensuring the long-term stability of the heat exchange efficiency of the finned heat exchange tube, and avoiding the decrease in heat exchange efficiency caused by material adhesion. 4. By using the feeding component, buffer component, preheating component and striking component in a coordinated manner, the system is open during feeding and closed when not feeding. When closed, hot flue gas is drawn in to preheat the material. After preheating, the material is automatically fed in. The closed-loop coordination of synchronous striking reduces heat loss from the feeding port, reduces the impact of cold material on the kiln's thermal field, and increases the temperature of the material before it enters the kiln.

[0024] Please refer to the attached document. Figure 10 - Appendix Figure 12The top of the L-shaped base 1 is equipped with a preheating component for preheating the material dispensed from the storage bin 3.

[0025] The fixed inclined plate 605 is set with an inclined surface structure on the side near the cylinder 602, and the end of the push rod 603 near the fixed inclined plate 605 is always in contact with the inclined surface of the fixed inclined plate 605.

[0026] Please refer to the attached document. Figure 12 - Appendix Figure 14 The top of the L-shaped base 1 is provided with a striking assembly for striking the bottom of the inclined conveyor plate 503. The striking assembly includes a fixing frame 701, which is fixedly installed on the bottom of the inclined conveyor plate 503. Two sets of second sliding rods 702 are slidably connected in the middle of the fixing frame 701. Each set of second sliding rods 702 has no less than three rods. The bottom of each second sliding rod 702 and the bottom of the fixing frame 701 are fixedly connected to a third spring 703.

[0027] The third spring 703 is sleeved on the outside of the second sliding rod 702. The bottom of each second sliding rod 702 is located on the movement path of the wave-shaped structure of the side U-shaped frame 508, and the gap between the wave-shaped structures of the side U-shaped frame 508 is adapted to the size of the second sliding rod 702.

[0028] Based on the above technical solution, embodiments of the present invention also provide a working principle for an energy-saving glass melting furnace, including the following: The initial state is as follows: The two buffer plates 515 abut against each other, the first spring 514 is in a contracted state, the storage bin 3 puts the material into the inclined conveyor plate 503, and at this time the staff controls the electric telescopic rod 501 to start working through the external control panel.

[0029] The working steps of the feeding component and the buffer component working together are as follows: Please refer to the attached document. Figure 4 - Appendix Figure 6The electric telescopic rod 501 pushes the pusher plate 502 towards the underside of the storage bin 3 via its output shaft, sliding it onto the inclined conveyor plate 503. At this time, material accumulates on the inclined conveyor plate 503. The pusher plate 502 pushes the material, causing it to fall along the trajectory of the inclined conveyor plate 503. The material then lands above the two flame deflectors 510. Simultaneously, as the pusher plate 502 moves towards the underside of the storage bin 3, its upper surface comes into contact with the bottom of the storage bin 3. Therefore, the bottom of the storage bin 3 is no longer connected to the outside, and no more material is added to the storage bin 3. At the maximum extension of the electric telescopic rod 501, the upper surface of the pusher plate 502 still abuts against the bottom of the storage bin 3. The pusher plate 502 drives the first connecting rod 505 to slide along the middle of the fixed plate 504. The first connecting rod 505 then drives the rectangular plate 506 to move synchronously. The rectangular plate 506 then drives the two second connecting rods 507 to swing away from the center of the rectangular plate 506 with their connection points to the rectangular plate 506 as the axis. Then, the two second connecting rods 507 respectively drive the side U-shaped frame 508 to move along the guide rod 509. The two side U-shaped frames 508 respectively move along the guide rod 509. The guide rod 509 moves away from the center of the first connecting rod 505, and the two side U-shaped frames 508 drive the two flame deflectors 510 to move synchronously. The two flame deflectors 510 drive the buffer plate 515 to move synchronously. The two buffer plates 515 no longer collide with each other. At this time, the feed port 4 is connected to the outside. At the same time, the first spring 514 pushes the first sliding rod 513 to slide outward of the flame deflector 510 through its elastic extension force. Thus, the buffer plate 515 also no longer collide with the flame deflector 510. At this time, the material on the upper surface of the flame deflector 510 enters the inner cavity of the furnace shell 2 through the feed port 4. Furthermore, the material adhering to the upper surface of the flame deflector 510 is scraped off by the lower surface of the inclined conveyor plate 503, preventing the material from adhering to the upper surface of the flame deflector 510. When the electric telescopic rod 501 begins to retract, the above-mentioned reverse working steps are repeated. In contrast, when the two buffer plates 515 come into contact, the two buffer plates 515 respectively drive their first sliding rods 513 to slide towards the inner cavity of the flame deflector 510 and compress the first spring 514 again. The material of the two buffer plates 515 is made of sponge silicone rubber, which can be used in high-temperature environments to avoid rigid collisions with the outer metal of the flame deflector 510.

[0030] By setting up the feeding components, the feed inlet 4 is shielded for most of the working cycle during the opening and closing of the two flame deflectors 510. This reduces the heat loss from the inside of the furnace shell 2 to the outside, shortens the time and window of high-temperature radiation from the furnace shell 2 to diffuse outward, and only opens the feed inlet 4 for a short period of time during material feeding to meet the material conveying needs. At the same time, it provides sufficient residence time for the subsequent preheating components, ensuring that the material receives sufficient heat exchange in front of the furnace shell 2. It also avoids the unfavorable condition of new material constantly covering unmelted material due to continuous feeding, thereby improving melting efficiency.

[0031] The operating steps of the preheating component are as follows: When the two buffer plates 515 abut against each other and separate the feed inlet 4 from the outside, the second spring 604 is in a stretched state, and the push rod 603 is located at the deepest part of the inner cavity of the cylinder 602. As described above, during the process of the two buffer plates 515 separating, the flame deflector 510 drives the fixed rod 601 to move relative to each other, and the fixed rod 601 drives the cylinder 602 to start moving along the inclined surface of the fixed inclined plate 605. With the continuous movement of the cylinder 602, the second spring 604 continuously pushes one end of the push rod 603 against the inclined surface of the fixed inclined plate 605 through its elastic contraction force. Then the space formed by the cylinder 602 and the push rod 603 becomes larger and larger. At this time, the first one-way valve 607 is in the open state and the second one-way valve 610 is in the closed state. Then the hot flue gas in the feed inlet 4 enters the stainless steel metal hose 606 through the smoke inlet 512. During the process of the two buffer plates 515 approaching each other, the above process is repeated in the opposite direction. The working steps are as follows. Since the retraction and rest time of the two electric telescopic rods 501 is greater than their extension and rest time, it can be concluded that the material is stored on the upper surface of the flame baffle 510 for a longer time than it is placed inside the furnace shell 2. Therefore, when the two buffer plates 515 are fully closed, the hot flue gas in the inner cavity of the cylinder 602 enters the interior of the finned heat exchange tube 608 through the metal corrugated pipe 609. After multiple extractions of hot flue gas, the inner cavity of the finned heat exchange tube 608 can be filled with hot flue gas. Thus, the two finned heat exchange tubes 608 can preheat the material on the upper surface of the flame baffle 510, so that the material can be sent into the furnace shell 2 after preheating. This can alleviate the heat demand of the material in the furnace shell 2 during the heating and melting stage, accelerate the melting reaction process of the material, and thus help maintain the stable thermal state of the furnace. The excess flue gas is put into the waste heat boiler module 612 through the exhaust pipe 611 via the finned heat exchange tube 608.

[0032] By setting up the preheating component, the material is preheated before being sent into the furnace shell 2, which reduces the heat required to heat up to the molten state and speeds up the melting reaction process. This helps to maintain the stability of the furnace's thermal state and allows the hot flue gas that was originally lost at the feed inlet 4 to be captured again and used to preheat the material to be fed, thus converting the lost heat into effective heat.

[0033] The steps for tapping the component are as follows: As shown above, when the two side U-shaped frames 508 move along the guide rod 509, the wave-like structure on the side U-shaped frames 508 continuously passes over the bottom of the second sliding rod 702. The protruding part pushes the second sliding rod 702 vertically upwards, while the second sliding rod 702 slides vertically upwards onto the fixed frame 701. The second sliding rod 702 compresses the third spring 703, and the top of the second sliding rod 702 abuts against the bottom of the inclined conveyor plate 503. In the recessed part, it does not abut against the bottom of the second sliding rod 702. The compressed third spring 703, through its elastic extension force, slides the second sliding rod 702 vertically downwards onto the fixed frame 701. The top of rod 702 no longer touches the bottom of the inclined conveyor plate 503. Therefore, multiple second sliding rods 702 continuously touch the bottom of the inclined conveyor plate 503. Thus, when the two flame deflectors 510 no longer block the connection between the feed inlet 4 and the outside, that is, when the material is fed into the inner cavity of the furnace shell 2 through the feed inlet 4, multiple second sliding rods 702 touch the bottom of the inclined conveyor plate 503. This can prevent the material from being stuck on the inclined surface of the inclined conveyor plate 503. At the same time, because the inclined conveyor plate 503 is fixedly connected to the finned heat exchange tube 608, the finned heat exchange tube 608 located in the material pile can also be prevented from being attached to the material during the process of the second sliding rods 702 striking the inclined conveyor plate 503.

[0034] By setting up the striking component, multiple second sliding rods 702 continuously strike the bottom of the inclined conveyor plate 503 under the drive of the wave-like structure of the side U-shaped frame 508, preventing material from accumulating on the inclined surface of the inclined conveyor plate 503. As the material slides down the inclined surface, the continuous striking vibration breaks the adhesion between the material and the surface of the inclined conveyor plate 503, allowing the material to slide smoothly onto the upper surface of the flame deflector plate 510, and preventing material from adhering to the surface of the finned heat exchange tube 608. The finned heat exchange tube 608 is fixedly connected to the inclined conveyor plate 503, and the striking vibration is transmitted to the finned heat exchange tube 608 through the inclined conveyor plate 503, shaking off the material adhering to the surface of the finned heat exchange tube 608, ensuring the long-term stability of the heat exchange efficiency of the finned heat exchange tube 608, and avoiding the attenuation of heat exchange efficiency due to material adhesion.

[0035] By using the feeding component, buffer component, preheating component and striking component in a coordinated manner, the system is open during feeding and closed when not feeding. When closed, hot flue gas is drawn in to preheat the material. After preheating, the material is automatically fed in. The closed-loop coordination of synchronous striking reduces heat loss from the feeding port, reduces the impact of cold material on the kiln's thermal field, and increases the temperature of the material before it enters the kiln.

[0036] 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 claims and their equivalents.
