Description

Technical Field

[0001] This invention relates to the field of kilns and discloses a glass melting furnace. Background Technology

[0002] The arch bricks are a key refractory structure supporting the kiln's dome, located on its side and subjected to prolonged exposure to high temperatures and mechanical loads. In existing technologies, cooling of the arch bricks primarily involves directly blowing heat through high-pressure air ducts onto the outer surface of the bricks. However, due to the low thermal conductivity of the refractory materials, heat is difficult to conduct rapidly from the interior to the surface, resulting in a large internal temperature gradient and concentrated thermal stress, making the bricks highly susceptible to cracking and even fracture. Furthermore, simply increasing the high-pressure airflow does not improve internal heat dissipation; instead, it may exacerbate thermal shock damage due to rapid surface cooling. Therefore, a glass melting furnace with improved heat dissipation for the arch bricks is urgently needed. Summary of the Invention

[0003] The purpose of this invention is to provide a glass melting furnace to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] A glass melting furnace according to a first aspect of the present invention includes: The kiln body has a kiln roof on its top side, and side support groups are respectively provided between the kiln roof and the kiln body on both sides. The side support groups include multiple arch bricks arranged along the kiln body. A cooling device includes a power assembly and cooling pipes. A partition rib is provided inside the cooling pipe, extending axially along the cooling pipe. The partition rib divides the interior of the cooling pipe into an air inlet channel and an air outlet channel. One end of the partition rib is a first closed end, forming a first connecting gap between the first closed end and the partition rib. The air inlet channel and the air outlet channel are interconnected through the first connecting gap. An air inlet head is connected to the cooling pipe away from the first closed end and corresponding to the air inlet channel. An air inlet hole is provided on one side of the air inlet head, capable of generating airflow along the surface of the arch brick. The air inlet hole is interconnected with the air inlet channel. There are multiple cooling pipes, with the first closed ends of the multiple cooling pipes respectively inserted into multiple arch bricks. The power assembly is connected to multiple air outlet channels, enabling the multiple air outlet channels to generate negative pressure airflow.

[0005] This technical solution has at least the following beneficial effects: The cooling pipe is inserted into the arch brick. When heat dissipation from the arch brick is required, the power assembly creates negative pressure in multiple air outlet channels. At this time, ambient air forms an airflow along the surface of the arch brick, carrying away some of the heat from the outer surface. The airflow enters through the air inlet of the air inlet head, flows along the air inlet channel to the first closed end, then flows around the first connecting gap to the air outlet channel, and finally is drawn into the power assembly from the air outlet channel. During the airflow process inside the cooling pipe… This process carries away some of the heat transferred from the arch bricks to the cooling pipes. By creating an airflow along the surface of the arch bricks, high-pressure air is not blown directly onto the surface of the arch bricks. This effectively reduces the possibility of airflow entering the kiln through the gaps between the arch bricks and affecting the working environment inside the kiln. Furthermore, it can carry away heat from inside the arch bricks, effectively solving the problem of blowing air only onto the surface of the arch bricks while the internal heat is difficult to dissipate. This significantly reduces the internal temperature gradient and thermal stress of the arch bricks, thereby effectively preventing cracks and extending the service life of the arch bricks.

[0028] Reference Figure 1 , Figure 2 and Figure 3 According to a first aspect of the present invention, a glass melting furnace includes a furnace body 100 and a cooling device. A furnace roof 110 is provided on the top side of the furnace body 100. Side support assemblies are respectively provided between the furnace roof 110 and the furnace body 100 on both sides. The side support assemblies include a plurality of arch bricks 120 arranged along the furnace body 100. The cooling device includes a power assembly and a cooling pipe 210. A partition rib 220 is provided inside the cooling pipe 210. The partition rib 220 extends axially along the cooling pipe 210 and divides the interior of the cooling pipe 210 into an air inlet channel 211 and an air outlet channel 212. One end of the partition rib 220 is a first closed end, and a first closed end is formed between the first closed end and the partition rib 220. The air inlet channel 211 and the air outlet channel 212 are interconnected through the first connecting gap 213. The cooling pipe 210 is connected to an air inlet head 230 at a position away from the first closed end and corresponding to the air inlet channel 211. An air inlet hole 231 is provided on one side of the air inlet head 230. The air inlet hole 231 can form an airflow along the surface of the arch brick 120. The air inlet hole 231 is interconnected with the air inlet channel 211. There are multiple cooling pipes 210. The first closed ends of the multiple cooling pipes 210 are respectively inserted into the multiple arch bricks 120. The power component is connected to the multiple air outlet channels 212. The power component can make the multiple air outlet channels 212 form negative pressure air outlet.

[0029] As described above, the cooling pipe 210 is inserted into the arch brick 120. When heat dissipation is required for the arch brick 120, the power assembly creates negative pressure airflow in the multiple air outlet channels 212. At this time, ambient air forms an airflow along the surface of the arch brick 120, carrying away some of the heat from the outer surface of the arch brick 120. The airflow enters through the air inlet 231 of the air inlet head 230. The airflow flows along the air inlet channel 211 to the first closed end, then flows around the first connecting gap 213 to the air outlet channel 212, and finally is drawn into the power assembly from the air outlet channel 212. This process of airflow flowing inside the cooling pipe 210 is described. In this process, some of the heat transferred from the arch brick 120 to the cooling pipe 210 is carried away. Thus, by forming an airflow along the surface of the arch brick 120, high-pressure air is not directly blown onto the surface of the arch brick 120, effectively reducing the possibility of airflow entering the kiln through the gaps between the arch bricks 120 and affecting the working environment inside the kiln. Furthermore, heat can be carried away from the inside of the arch brick 120, effectively solving the problem of only blowing air onto the surface of the arch brick 120 while the internal heat is difficult to dissipate. This significantly reduces the internal temperature gradient and thermal stress of the arch brick 120, thereby effectively preventing crack formation and extending the service life of the arch brick 120.

[0030] In the above embodiment, cooling devices can be provided on both sides of the side support group of the kiln body 100 to improve the heat dissipation effect on the multiple arch bricks 120 on both sides of the kiln body 100.

[0031] There are various structural forms in which the power assembly creates negative pressure airflow through multiple air outlet channels 212. For example, the power assembly includes a vacuum pump that evacuates the interior of the multiple air outlet channels 212. In this embodiment, referring to... Figure 1 As shown, the power assembly includes a fan 241 and a main air duct 242. The main air duct 242 is connected to the air outlet of the fan 241. Multiple cooling pipes 210, located away from the first closed end and corresponding to the air inlet channel 211, are respectively connected to air outlet pipes 214, which are connected to the main air duct 242. When the fan 241 operates, it supplies high-speed airflow into the main air duct 242. This creates a negative pressure inside the multiple connected air outlet pipes 214, thereby creating airflow from the air inlet channel 211 to the air outlet channel 212 within the multiple cooling pipes 210.

[0032] To further improve the cooling effect on the arch foot brick 120, refer to Figure 2As shown, the present invention also includes multiple air blowing pipes 250 connected to the main air pipe 242. Each of the multiple air blowing pipes 250 has an air blowing head 261 connected to its end away from the main air pipe 242. Each of the multiple air blowing heads 261 has an air blowing hole 262 on one side, and the multiple air blowing holes 262 are connected to the multiple air blowing pipes 250. The multiple air blowing holes 262 can form an airflow flowing along the surface of the multiple arch bricks 120. The air blowing pipes 250 utilize the positive pressure airflow from the main air pipe 242 to blow airflow onto the surface of the arch bricks 120, forming a combined cooling mode of blowing and suction with the negative pressure airflow from the air inlet head 230. This surface blowing and suction accelerates heat dissipation from the outer surface of the brick, and, in conjunction with internal cooling, further reduces the overall temperature gradient of the arch bricks 120, improving the cooling effect.

[0033] If the airflow directions of the blowing and suction are not reasonable, they may cancel each other out or form vortices, reducing cooling efficiency. Therefore, in this embodiment, in one of the adjacent blowing heads 261 and one air inlet head 230, one of the blowing holes 262 and the air inlet hole 231 is arranged upwards, and the other is arranged downwards. The blowing holes 262 and the air inlet hole 231 are arranged in opposite directions, so that the blown cold air and the drawn-in hot air form a larger cooling coverage area, effectively preventing airflow short-circuiting and improving heat exchange efficiency; at the same time, the reverse arrangement also helps to form a uniform cooling air film on the surface of the arch brick 120.

[0034] After the fan 241 supplies airflow into the main air duct 242, as the airflow continuously flows within the main air duct 242, the airflow temperature at the end of the main air duct 242 is higher. To also ensure a cooling effect for the airflow near the end of the main air duct 242, refer to... Figure 4As shown, in this embodiment, a partition plate 243 is provided on the inner side of the main air duct 242. The partition plate 243 extends along the axial direction of the main air duct 242 and divides the interior of the main air duct 242 into a first airflow zone 244 and a second airflow zone 245. The end of the main air duct 242 away from the fan 241 is a second closed end. A second connecting gap 246 is formed between the second closed end and the partition plate 243. The first airflow zone 244 and the second airflow zone 245 are interconnected through the second connecting gap 246. The first airflow zone 244 and the second airflow zone 245 correspond to the air outlet end of the fan 241, respectively. A plurality of air outlet pipes 214 and a plurality of air blowing pipes 250 are respectively connected to the first airflow zone 244. An exhaust pipe 270 is provided on the top side of the main air duct 242 and is connected to the first airflow zone 244. The partition plate 243 divides the interior of the main air duct 242 into two zones: a first airflow zone 244 and a second airflow zone 245. When the fan 241 is working, part of the exhaust air enters the first airflow zone 244, and part of the exhaust air enters the second airflow zone 245. The part of the exhaust air entering the first airflow zone 244 provides negative pressure suction and blowing to the multiple cooling pipes 210 between the fan 241 and the exhaust pipe 270. The part of the exhaust air entering the second airflow zone 245 flows around the second connecting gap 246 and then enters the first diversion zone, providing negative pressure suction and blowing to the multiple cooling pipes 210 between the second closed end and the exhaust pipe 270. The two airflows flowing in opposite directions in the first airflow zone 244 converge at the exhaust pipe 270 and are discharged outward from the exhaust pipe 270. This helps to ensure the blowing and cooling effect of the cooling pipes 210 located at the end of the main air duct 242, thereby improving the cooling uniformity of the multiple arch bricks 120.

[0035] Understandably, in order to ensure that the airflow sent from the fan 241 to the second airflow zone 245 can be routed into the first airflow zone 244 and discharged from the exhaust pipe 270, regulating valves can be installed in the first airflow zone 244 and the second airflow zone 245 respectively, and the amount of air supplied to the second airflow zone 245 can be increased by regulating valves.

[0036] To create a smoother airflow onto the surface of the arch brick 120, in this embodiment, multiple air inlets 231 extend in an arc shape around the axis of their corresponding cooling pipes 210, and multiple air outlets 262 extend in an arc shape around the axis of their corresponding air outlets 250. The arc-shaped holes allow the airflow to diffuse in a fan shape circumferentially, increasing the coverage area of ​​the cooling airflow on the surface of the arch brick 120, resulting in more uniform cooling and further reducing the impact of the airflow on the surface of the arch brick 120. Simultaneously, the arc-shaped structure also increases the uniformity of the outlet air velocity.

[0037] The partition ribs 220 can be horizontally arranged inside the cooling pipe 210. However, to enhance the structural strength of the partition ribs 220, in this embodiment, multiple partition ribs 220 are respectively arranged vertically inside multiple cooling pipes 210. The vertically arranged partition ribs 220 increase the vertical support of the cooling pipe 210, which helps reduce the risk of deformation of the cooling pipe 210 within the arch brick 120. Furthermore, the vertical separation allows the air inlet channel 211 and air outlet channel 212 to be arranged side-by-side on the cross-section of the cooling pipe 210, which helps maintain the horizontal posture of the cooling pipe 210 when inserted into the arch brick 120. Additionally, the air inlet head 230 and air outlet pipe 214 can be respectively arranged on both sides of the cooling pipe 210, facilitating pipe connection.

[0038] In some embodiments, the cross-sectional shape of the cooling pipe 210 may be circular. In other embodiments, the cross-sectional shape of the plurality of cooling pipes 210 is elliptical, and the major axis of the cross-section of the plurality of cooling pipes 210 is arranged along the length direction of the kiln body 100. The elliptical cross-section has a larger cross-sectional area for the same perimeter, which is beneficial to increasing the flow capacity of the airflow channel; at the same time, the major axis along the length direction of the kiln body 100 increases the contact area with the bricks and improves the heat conduction efficiency.

[0039] The cooling pipes 210 are directly inserted into the arch bricks 120, forming a rigid contact. During thermal expansion, this can generate compressive stress, leading to brick cracking or deformation of the cooling pipes 210. In this embodiment, each of the arch bricks 120 has mounting holes on its side away from the kiln top 110. The cooling pipes 210 are inserted into these mounting holes, and a breathable buffer layer 280, such as ceramic fiber felt, is provided between each cooling pipe 210 and the mounting holes. The breathable buffer layer 280 provides elastic cushioning between the cooling pipes 210 and the arch bricks 120, absorbing the stress generated by thermal expansion and helping to prevent brick cracking or deformation of the cooling pipes 210. Furthermore, the breathable buffer layer 280 allows a small amount of air to pass through, aiding in heat dissipation without affecting the airflow circulation of the cooling pipes 210.

[0040] To facilitate the insertion of the cooling pipes 210 into the mounting holes, in this embodiment, multiple breathable buffer layers 280 are respectively sleeved on the outer sides of the multiple cooling pipes 210, and multiple support mesh sleeves 290 are respectively provided in the mounting holes. The outer sides of the multiple breathable buffer layers 280 abut against the inner sides of the multiple support mesh sleeves 290. The support mesh sleeves 290 provide stable radial support for the breathable buffer layers 280, preventing them from shifting or collapsing during use, and ensuring the long-term stability of the buffering and breathability effects. At the same time, the support mesh sleeves 290 also enhance the structural strength of the mounting holes. They can be made of metal, giving the support mesh sleeves 290 a certain degree of elastic deformation capability.

[0041] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
