Description

Technical Field

[0001] The invention belongs to the technical field of kiln internal observation, and in particular relates to a kiln production internal observation device. Background Art

[0002] Liquid crystal glass is the base material of liquid crystal display panels and an important component of flat panel displays. During the production process of liquid crystal substrate glass, qualified glass melt is achieved through kiln melting, platinum channel clarification and homogenization. The kiln is an important equipment for melting glass raw materials.

[0003] At present, in the manufacturing process of liquid crystal glass, the kiln is an important equipment for melting raw materials. The kiln structure is roughly composed of a crown, a breast wall, a pool wall and a pool bottom. The electrode natural gas burner is used as the melting kinetic energy to melt the raw materials. However, due to the long-term high temperature and erosion of the glass liquid, and the erosion of the positive pressure of the natural gas burner airflow in the furnace, changes will inevitably occur in the kiln, resulting in changes in the crown of the wall inside the pool furnace, affecting the state inside the pool furnace, thereby changing the melting working state of the pool furnace.

[0004] When changes occur in the kiln, they are not easy to be discovered. Therefore, according to the process requirements, checking the status of the furnace has become a normal requirement. It is necessary to check the status of the glass liquid, the combustion gun, the flame, the trend of the material mountain, the feeding situation, the status of the refractory materials in the furnace, and the coking status of the crown to ensure that the kiln can melt qualified glass liquid normally. The current method used by operators is to wear head covers, goggles, high-temperature resistant gloves, and heat-insulating clothing and hold goggles to check the status of the furnace from a distance.

[0005] However, there are the following problems: the kiln is under positive pressure, and the operator has difficulty moving after wearing labor protection equipment. Due to the furnace pressure, high-temperature flames and gases will spray out of the furnace after the observation port is opened, which can easily cause high-temperature impact burns to the operator. Moreover, the hand-held fire-viewing mirror cannot observe the furnace status at close range, and it is not possible to observe closely when observing at the front feeding port, so the furnace status cannot be viewed in all directions. When the distance is slightly close, the fire-viewing mirror is easy to break, and the headgear goggles are easy to burn. The safety of the operator cannot be guaranteed, resulting in a blurred state when viewing the furnace situation, and it is impossible to make a completely correct judgment, which affects the personal safety of the operator, the working safety of the pool furnace, and the stability of the glass liquid process. The labor protection fire-viewing mirror has great loss and the cost of use is extremely high. Summary of the invention

[0006] The purpose of the present invention is to provide a kiln production internal observation device, which, on the one hand, is used to solve the technical defect that the prior art cannot observe the internal state of the kiln at a close distance; on the other hand, it is used to solve the technical defect that the prior art cannot ensure the safety of operators.

[0015] Furthermore, the heat insulation protection frame is a rectangular structure and is made of stainless steel.

[0016] Furthermore, the heat-insulating and fire-proof layer is made of an alumina fiber blanket.

[0017] Furthermore, the thermal insulation buffer layer is a high-dimensional board.

[0020] Furthermore, the handle is a structure with one end open and the other end closed, and the open end is connected to the heat insulation component.

[0021] Furthermore, the bolts are provided in plurality.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. When observing the production conditions inside the kiln, the insulation component can effectively isolate the high-temperature flame and high-temperature gas inside the kiln, providing a safe working environment for the operator, so that the operator can use the handle to observe the internal conditions of the kiln closely and carefully; secondly, setting the observation component on the insulation component avoids the problem of the observation component breaking during the observation process.

[0024] 2.

[0027] 5. Alumina fiber blanket has extremely low thermal conductivity, which can effectively prevent the transfer of heat, thereby significantly reducing heat loss through the thermal insulation and fireproof layer.

[0028] 6. High-dimensional boards usually have a lower thermal conductivity, which can effectively reduce the transfer of heat and thus have a good thermal insulation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Liquid crystal glass is the base material of liquid crystal display panels and an important component of flat panel displays. During the production process of liquid crystal substrate glass, qualified glass melt is achieved through kiln melting, platinum channel clarification and homogenization. The kiln is an important equipment for melting glass raw materials.

[0043] At present, in the manufacturing process of liquid crystal glass, the kiln is an important equipment for melting raw materials. The kiln structure is roughly composed of a crown, a breast wall, a pool wall and a pool bottom. The electrode natural gas burner is used as the melting kinetic energy to melt the raw materials. However, due to the long-term high temperature and erosion of the glass liquid, and the erosion of the positive pressure of the natural gas burner airflow in the furnace, changes will inevitably occur in the kiln, resulting in changes in the crown of the wall inside the pool furnace, affecting the state inside the pool furnace, thereby changing the melting working state of the pool furnace.

[0044] When changes occur in the kiln, they are not easy to be discovered. Therefore, according to the process requirements, checking the status of the furnace has become a normal requirement. It is necessary to check the status of the glass liquid, the combustion gun, the flame, the trend of the material mountain, the feeding situation, the status of the refractory materials in the furnace, and the coking status of the crown to ensure that the kiln can melt qualified glass liquid normally. The current method used by operators is to wear head covers, goggles, high-temperature resistant gloves, and heat-insulating clothing and hold goggles to check the status of the furnace from a distance.

[0045] However, there are the following problems: the kiln is under positive pressure, and the operator has difficulty moving after wearing labor protection equipment. Due to the furnace pressure, high-temperature flames and gases will spray out of the furnace after the observation port is opened, which can easily cause high-temperature impact burns to the operator. Moreover, the hand-held fire-viewing mirror cannot observe the furnace status at close range, and it is not possible to observe closely when observing at the front feeding port, so the furnace status cannot be viewed in all directions. When the distance is slightly close, the fire-viewing mirror is easy to break, and the headgear goggles are easy to burn. The safety of the operator cannot be guaranteed, resulting in a blurred state when viewing the furnace situation, and it is impossible to make a completely correct judgment, which affects the personal safety of the operator, the working safety of the pool furnace, and the stability of the glass liquid process. The labor protection fire-viewing mirror has great loss and the cost of use is extremely high.

[0046] In order to solve the above technical defects, the inventor provides a kiln production internal observation device.

[0047] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0048] like Figure 1-Figure 5 As shown, the kiln production internal observation device includes a heat insulation component, which is used to block the kiln observation port; the observation component and the handle 8 are installed on the top of the heat insulation component and are spaced apart from each other; wherein the handle 8 is made of stainless steel, and an insulating material 7 is provided on the outside of the handle 8. When observing the inside of the kiln, the operator holds the handle 8 with both hands, places the heat insulation component on the kiln observation port, blocks the kiln observation port, blocks the high-temperature flame and gas inside the kiln, avoids harm to the operator, and allows the operator to observe the internal state of the kiln closely and carefully; and, under the influence of the heat insulation component, the high temperature inside the kiln can be gradually attenuated to avoid burning the observation component, thereby solving the defects of the prior art. Figure 1 and Figure 2 As shown, the heat insulation assembly includes a heat insulation protection frame 1, a heat insulation fireproof layer 2 and a heat insulation buffer layer 3. The heat insulation protection frame 1, the heat insulation fireproof layer 2 and the heat insulation buffer layer 3 are arranged from top to bottom and fixed to each other by bolts 4 to form a whole. A plurality of bolts 4 are arranged to further improve the reliability of fixation. Subsequently, a fixed card slot 9 is opened on the heat insulation protection frame 1. The fixed card slot 9 is made of 310S grade stainless steel, which has good oxidation resistance, corrosion resistance, high temperature resistance, and can continue to work at high temperature. The fixed card slot 9 penetrates to the bottom of the heat insulation buffer layer 3, and then the observation assembly is installed in the fixed card slot 9 to complete the assembly process. Furthermore, the observation assembly includes a fire-viewing mirror 10 and a quartz glass 11. The fire-viewing mirror 10 adopts a professional-grade fire-viewing mirror with a light transmittance of more than 93%. It can effectively block the damage of strong light and radiation light to the glasses, especially the ultraviolet rays at 320nm that are harmful to the eyes. It has good absorption performance and a high observable temperature range. It can be used between 800℃ and 2200℃. The fire can be seen more clearly, especially the furnace wall and material heating conditions inside the kiln can be observed clearly. The length of the fire-viewing mirror 10 and the quartz glass 11 is preferably 50-800mm, and the height is preferably 50-500mm. The fire-viewing mirror 10 is arranged on the top of the quartz glass 11. The quartz glass 11 has extremely high high temperature resistance, can maintain transparency and stability at extremely high temperatures, and is not easy to deform or break. The fire-viewing mirror 10 is arranged on the quartz glass 11, which further enhances the convenience and clarity of observation.

[0049] like Figure 1As shown, the heat insulation protection frame 1 is a rectangular structure and is made of 310S grade stainless steel. It has good oxidation resistance, corrosion resistance, high temperature resistance, and can work continuously at high temperatures. The heat insulation fireproof layer 2 is made of alumina fiber blanket, with an operating temperature of 1450℃-1600℃ and a melting point of 1840℃. It has good heat resistance and stability, low density, good insulation, and small heat capacity. It not only reduces the weight, but also has excellent heat insulation performance and better fit. The heat insulation buffer layer 3 uses a high-dimensional board, which has high high-temperature stability, low thermal conductivity and low heat capacity, hardness and high internal bonding strength, thermal shock resistance and erosion resistance, and can directly contact the flame, so that it has machinability and cutting performance, and is easy to install and use.

[0050] like Figure 1 and Figure 4 As shown, 310S stainless steel bolts are used. Stainless steel has excellent residual strength and rigidity under high temperature conditions. A fixed pad brick 5 and a fixed nut 6 are provided on the bolt 4. The fixed pad brick 5 is made of mullite and has the characteristics of high temperature resistance, high strength and low thermal conductivity. The fixed pad brick 5 is arranged between the bolt 4 and the fixed nut 6, and the fixed pad brick 5 is located on the top of the thermal insulation protection frame 1.

[0051] like Figure 1 and Figure 3 As shown, the handle 8 is a structure with one end open and the other end closed, and the open end is welded to the heat insulation component.

[0052] During the observation, the operator wears necessary labor protection products, informs the process operator to do a good job of process control, and one person is on site for protection and communication. The on-site operator holds the device in one hand and opens the observation port plug brick with the other hand. After opening, the plug brick is placed on the refractory material, and then the device is placed on the kiln observation port with both hands through the handle 8. The operator observes the front and middle part of the kiln, the two sides and the top of the kiln from a close distance, and restores the equipment process to its original state after the inspection.

[0053] When observing the front of the kiln, wear necessary labor protection supplies, notify the process operator to do a good job of process control, one person on site for protection and communication, and when the front observation port equipment is withdrawn and unobstructed, hold the device with both hands for inspection, and closely inspect the middle and rear positions of the kiln, the status of the two sides and the top of the top, and the status of the front feeding port position, shape and coking. After the inspection, restore the equipment process to its original state. During the observation process, the device is resistant to high temperature and high temperature impact. The surface temperature of the operator's hand position is reduced from 55℃ to 38℃, and the surface temperature of the face, arms and upper body is reduced from 55℃ to 40℃, reducing the inspection time from more than 5 minutes to less than 2 minutes. It is safer, more reliable and more accurate, and the loss of the kiln process is minimized. The device is flexible and convenient to use, safe and reliable, and has strong controllability. It can be viewed up and down, left and right at a close distance, and can clearly view the internal state of the kiln and the status of the feeding port. It can better grasp the state of the kiln, make correct judgments, and make correct and effective measures in process countermeasures.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit its protection scope. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that after reading the present invention, those skilled in the art can still make various changes, modifications or equivalent substitutions to the specific implementation methods of the invention, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the invention.
