Description

Technical Field

[0001] The present application relates to the field of annealing furnaces, and in particular to a heat preservation system of an annealing furnace. Background Art

[0002] The insulation system of the glass annealing furnace is an important part to ensure its efficient operation and energy saving. The insulation structure of the annealing furnace usually includes the top insulation structure, the bottom insulation structure, the side insulation structure and the insulation curtains set in each partition. These structures are connected to different parts of the kiln body to ensure the sealing and insulation effect of the entire kiln body.

[0003] The insulation layer of existing glass annealing furnaces is mostly made of pieces of compressed insulation cotton spliced ​​and expanded, but there are often gaps at the joints of the expanded insulation cotton and the reserved operating pipes and equipment on the annealing furnace and the insulation cotton. Not only does it require the staff to spend a lot of time to check and fill them, it also leads to poor insulation performance of the annealing furnace. In addition, during the use of the annealing furnace, due to various unexpected factors, such as replacement of accessories, deposition of insulation cotton, etc., when the insulation barrier constructed by the insulation layer has holes, it is easy to cause the insulation performance of the glass annealing furnace to decline and affect the annealing of the glass.

[0059] The following is combined with Figure 1-10 This application is described in further detail.

[0060] The present application embodiment discloses a heat preservation system for an annealing furnace. Figure 1 and Figure 2, an insulation system for an annealing kiln, comprising a top insulation layer 1 arranged on the top of the annealing kiln, two groups of side wall insulation layers 2 arranged on both sides of the annealing kiln, and a bottom insulation layer 3 laid on the bottom of the annealing kiln. The top insulation layer 1 and the two groups of side wall insulation layers 2 are both spliced ​​by a plurality of insulation cotton modules 7. The bottom insulation layer 3 is laid with zirconium-containing ceramic fiberboard 31. The insulation system also includes a plurality of groups of movable curtains distributed at the intersections of each partition of a plurality of annealing kilns, two groups of electric baffle assemblies 4 distributed at the entrance and exit of the annealing kiln for opening and closing the entrance and exit of the annealing kiln, and a video monitoring module 6. The specific structure of the movable curtain is prior art and will not be repeated here. The video monitoring module 6 includes a monitoring controller 61, a plurality of monitoring devices 62 for collecting image information of the area where the annealing kiln is located, and a plurality of infrared cameras 63 for collecting the temperature of the top and both sides of the annealing kiln to form a thermal image of the annealing kiln. The monitoring controller 61 monitors the thermal insulation performance of the top insulation layer 1 and the two sets of side wall insulation layers 2 in real time based on the image information of the annealing kiln area and the thermal image of the annealing kiln, and sends maintenance information to the management personnel when an abnormality occurs. Through the top insulation layer 1, the side wall insulation layer 2, the bottom insulation layer 3, the movable curtain 5 and the electric baffle assembly 4, the thermal insulation performance of the annealing furnace can be improved, which is conducive to the smooth annealing of the glass; at the same time, based on the thermal insulation characteristics of the insulation layer, in conjunction with the setting of the video monitoring module 6, the external temperature of the thermal insulation layer of the annealing furnace is monitored in real time, and when the thermal insulation barrier constructed by the thermal insulation layer has holes due to various unexpected factors, such as accessory replacement, insulation cotton deposition, etc., the holes can be discovered in time and efficiently; in conjunction with the modular setting, even if the thermal insulation capacity of the thermal insulation cotton module 7 declines due to timeliness, resulting in a slight decline in the thermal insulation performance of the insulation layer to the unqualified critical point, the source of the abnormality can be accurately and efficiently determined, which is conducive to accurate and efficient repair of the insulation holes in the insulation layer, and on the basis of improving the thermal insulation performance of the annealing furnace, the stability of the thermal insulation performance of the annealing furnace is ensured, so as to effectively improve the efficiency and quality of the annealing process.

[0061] Reference Figure 3, the cross section of the insulation cotton module 7 is set in an isosceles trapezoid, and the adjacent insulation cotton modules 7 are relatively inverted. The insulation cotton module 7 in a compressed state is filled into the insulation layer of the annealing kiln, and the insulation cotton module 7 is stretched when it contacts its restraints, and the adjacent insulation cotton modules 7 are squeezed against each other to form an insulation layer. The insulation cotton module 7 with an isosceles trapezoidal cross section is adopted, and the adjacent insulation cotton modules 7 are relatively inverted. The extrusion force generated by the oblique waist edges that squeeze each other when expanding and stretching can be decomposed into the extrusion force in the horizontal and vertical directions, so that the adjacent insulation cotton modules 7 are more tightly combined at the abutment, which helps to build a more uniform and dense insulation layer and improve the insulation performance. And because the adjacent insulation cotton modules 7 are relatively inverted, when they are released from the restraints and expanded and stretched, the inverted insulation cotton module 7 generates pressure on the two adjacent insulation cotton modules 7 due to its own weight, which can further improve the tightness of the connection between the adjacent insulation cotton modules 7 and further improve the insulation performance of the insulation layer.

[0062] Reference Figure 3-Figure 5The insulation cotton module 7 includes a first module 71, a second module 72 and a third module 73 which are arranged in sequence along the horizontal direction. The first module 71, the second module 72 and the third module 73 are all provided with nano insulation films 74 along their vertical circumferences, and the two groups of nano insulation films 74 which are arranged opposite to each other in the first module 71, the second module 72 and the third module 73 are mutually penetrated with heat-resistant solid lines 75, and the nano insulation films 74 of the second module 72 are provided with a material change handle 76 at one end away from the annealing furnace. The material change handle 76 is cut from the material extending from the nano insulation film 74, and a reinforcement member such as plastic clips on both sides can be further provided on the outside thereof according to actual application requirements. The first module 71, the second module 72 and the third module 73 are used to form the thermal insulation cotton module 7, and nano thermal insulation films 74 are attached to the four vertical surfaces of the three modules, and the connection firmness between the nano thermal insulation film 74 and the modules it covers is strengthened by the heat-resistant solid line 75; the split design is adopted, when any thermal insulation cotton module 7 has thermal insulation holes or thermal insulation performance decreases due to aging or other various unexpected factors, the second module 72 is abutted against the first module 71 and the third module 73 by the nano thermal insulation film 74, at this time The second module 72 of the damaged insulation cotton module 7 can be pulled out by simply pulling the handle. At this time, the middle of the first module 71 and the third module 73 are vacant, and the remaining first module 71 and the third module 73 can be easily taken out, avoiding the phenomenon that the adjacent insulation cotton modules 7 are too tightly combined due to mutual expansion and extrusion, which makes it easy to bring out part of the tissue of other adjacent insulation cotton modules 7 when taking out the insulation cotton module 7. On the basis of effectively improving the replacement efficiency of the damaged insulation cotton module, the insulation performance of the surrounding insulation cotton modules 7 is guaranteed, and the maintenance loss is reduced. In addition, by arranging the nano insulation film 74 on the beveled edges of the adjacent insulation cotton modules 7, when the adjacent insulation cotton modules 7 are squeezed and deformed, the nano insulation film 74 can not only play the role of dividing and solidifying, but also can be interlocked with each other as the beveled edges are squeezed and deformed to improve the firmness and tightness of the connection, which helps to improve the insulation performance of the insulation layer.

[0063] It should be noted that Figure 3-Figure 5 The insulation cotton module 7 shown in the figure is only for showing the relative position relationship of each module and the connection relationship with the nano insulation film 74. In actual application, it can be drilled and embedded with accessories such as pipes, sensors, etc. according to application requirements; it can also be installed with bolts, nuts and other fixings according to the actual installation requirements of the annealing furnace. The insulation cotton module 7 produced by further shape modification using the above means also belongs to the scope of protection of the present invention.

[0064] Specifically, the first module 71, the second module 72 and the third module 73 are all made of aluminum silicate insulation cotton, the nano insulation diaphragm 74 is made of nano alumina film, the heat-resistant solid line 75 is made of aluminum silicate fiber line, and the density of the insulation cotton module 7 is greater than 150 kg / m³ under normal conditions. Aluminum silicate insulation cotton and nano alumina film are used to support the insulation cotton module 7. The nano alumina film has high hardness, high wear resistance and high heat resistance. The aluminum silicate insulation cotton also has excellent insulation performance and heat resistance. With the split design, on the basis of effectively improving the insulation performance of the insulation layer, the difficulty of replacing a single insulation cotton module 7 is effectively reduced, and the efficiency of inspection and maintenance of the insulation layer is improved.

[0065] Specifically, the zirconium-containing ceramic fiber board 31 is composed of aluminum silicate fiber, iron oxide and zirconium dioxide, and the weight ratio is: 830-870 parts of aluminum silicate fiber, 1-3 parts of iron oxide, and 129-167 parts of zirconium dioxide. The zirconium-containing ceramic fiber board 31 manufactured using the above ratio has excellent chemical stability, thermal stability, elasticity, and good thermal insulation performance and thermal shock resistance, further improving the thermal insulation performance of the annealing kiln insulation system.

[0066] Reference Figure 6 The electric baffle assembly 4 includes a frame 41 and an electric lifting door 42 which is slidably arranged on the frame 41 in the vertical direction, and the electric lifting door 42 is embedded with heat insulation materials. Auxiliary positioning assemblies 43 are arranged on both sides of the frame 41 in the vertical direction. Both sets of auxiliary positioning assemblies 43 include a mounting plate 431, a driving motor 432 and a driving screw 433. The driving screw 433 is rotatably arranged on the mounting plate 431 and arranged in the vertical direction. The output shaft of the driving motor 432 is coaxially connected with the driving screw 433. An auxiliary sliding rod 434 which is arranged parallel to the driving screw 433 is fixedly arranged on the mounting plate 431. The two sets of driving screws 433 and the auxiliary sliding rod 434 are both penetrated by an auxiliary support plate 435, which is threadedly connected with the driving screw 433. Both auxiliary support plates 435 abut against the bottom of the electric lifting door 42. Through the arrangement of the electric baffle assembly 4, the opening and closing of the entrance and exit of the annealing kiln can be effectively controlled. When the glass is annealed, the electric lift door 42 needs to be in a semi-open state for a long time to provide an opening for the glass to pass through and reduce heat dissipation. By setting an auxiliary positioning component 43, the electric lift door 42 at different heights can be supported and limited to avoid the sliding door phenomenon caused by electrical failure of the electric lift door 42 due to high temperature, thereby further improving the opening and closing safety of the electric lift door 42.

[0067] Reference Figure 7The monitoring controller monitors the thermal insulation performance of the top insulation layer and the two sets of side wall insulation layers in real time based on the image information of the annealing kiln area and the thermal image of the annealing kiln, and sends maintenance information to the management personnel when an abnormality occurs. The specific steps include:

[0068] A1. Real-time acquisition of thermal temperature values: The monitoring controller acquires the thermal image of the annealing kiln in real time to monitor the thermal temperature values ​​of the top insulation layer and the two sets of side wall insulation layers in real time;

[0069] A2. Determine whether there is an abnormality in the thermal insulation layer: If an abnormal temperature point with a thermal temperature value exceeding a preset temperature threshold appears in the thermal image of the annealing furnace, determine whether there is an abnormality in the thermal insulation layer based on the image information of the area where the annealing furnace is located;

[0070] A3. Send maintenance information: If there is any, send maintenance information to the management personnel to replace and repair the abnormal part of the insulation layer;

[0071] A4. Send abnormal prompt information: If it does not exist, send abnormal correction information to the management personnel to clear the source of abnormal temperature points that disturb the thermal image monitoring. The abnormal correction information includes abnormal clearing information and / or abnormal prompt information. The monitoring controller obtains the temperature conditions outside the annealing kiln in real time according to the thermal image of the annealing kiln. When the temperature in the area corresponding to the insulation layer outside the annealing kiln is too high and there is an abnormality, the cause of the temperature abnormality is determined by collecting the image of the annealing kiln area, and then the temperature abnormality point is eliminated, so as to realize real-time and efficient monitoring of the insulation layer of the annealing kiln. When the insulation barrier constructed by the insulation layer has holes due to various unexpected factors, such as replacement of accessories, deposition of insulation cotton, etc., the abnormal points of the holes can be found in time and efficiently; the insulation holes of the insulation layer can be accurately and efficiently repaired, and the stability of the insulation performance of the annealing kiln can be ensured on the basis of improving the insulation performance of the annealing kiln, so as to effectively improve the efficiency and quality of the annealing process.

[0072] Reference Figure 8 The above-mentioned method of judging whether there is an abnormality in the insulation layer based on the image information of the area where the annealing kiln is located specifically includes the following steps:

[0073] B1. Determine whether there is a source of cause: The image information of the area where the annealing kiln is located is identified through a preset anomaly recognition model to determine whether there is a source of cause at the abnormal temperature point in the thermal image of the annealing kiln; the anomaly recognition model is based on the ChatGPT4.0 model and is obtained by iterative training through historical anomaly data;

[0074] B2. If not, it is determined that there is an abnormal insulation layer at the abnormal temperature point;

[0075] B3. Determine whether the source is a component related to the annealing kiln: If so, determine that there is no insulation layer abnormality, identify the source through the abnormality recognition model, and determine whether the source is a component related to the annealing kiln;

[0076] B4. If yes, generate abnormal prompt information, which includes maintenance prompt information and monitoring and adjustment suggestions;

[0077] B5. Generate abnormality clearing information: If not, the source is determined to be a production interference factor, and abnormality clearing information is generated. Through the setting of the abnormality recognition model, based on the powerful image recognition capability of the ChatGPT4.0 model, after the abnormal temperature point is found, the source of the abnormal temperature can be efficiently identified, and then the corresponding treatment plan can be generated in a targeted manner to achieve efficient and rapid clearing of abnormal temperature points, ensure the thermal insulation performance of the annealing furnace insulation layer, and ensure the smooth progress of glass annealing work.

[0078] Reference Fig. 9 , the generating of abnormal prompt information specifically comprises the following steps:

[0079] C1. Based on the result of the source identification, determine whether the source is within its preset normal operating temperature threshold;

[0080] C2. Generate monitoring adjustment suggestions: If the situation is such that the layout relationship of multiple infrared cameras, source, annealing furnace and related equipment is transmitted to a preset solution adjustment model to generate monitoring adjustment suggestions, wherein the monitoring adjustment suggestions include at least one of source position adjustment suggestions, infrared camera angle adjustment suggestions and additional infrared camera suggestions; the solution adjustment model is a machine learning model, which is obtained through historical data iteration efficiency; the specific training steps of the machine learning model are prior art and will not be elaborated here;

[0081] C3. If not, a maintenance prompt message for abnormal operation of the source is generated. When the abnormal temperature source is a supporting component of the annealing furnace, and the source operates normally but interferes with the monitoring of the insulation layer, a monitoring adjustment suggestion is generated based on the layout relationship of multiple infrared cameras, source, annealing furnace and its related equipment through a pre-set solution adjustment model. On the basis of ensuring the normal operation of the source, the thermal image of the insulation layer is stably and completely collected, which helps to timely and efficiently discover the abnormal points of the insulation layer of the annealing furnace, ensure the stability of the insulation performance of the annealing furnace, and effectively improve the efficiency and quality of the annealing process.

[0082] Reference Fig.10 The method of transmitting the layout relationship of multiple infrared cameras, source, annealing kiln and their associated equipment to the preset scheme adjustment model to generate monitoring adjustment suggestions specifically includes the following steps:

[0083] S1. The solution adjustment model obtains the specification parameter information of the source and determines whether it is a movable component;

[0084] S2. If not, extract and determine the missing insulation layer area in the thermal image of the annealing furnace based on the layout relationship of multiple infrared cameras, the source of the radiation, the annealing furnace and their associated equipment, and generate a suggestion for adding infrared cameras;

[0085] S3. If it is a movable component, determine the effective moving range of the source, and judge whether there is an annealing furnace area within the effective moving range that is not in the insulation layer area and the area size meets the specification requirements of the source;

[0086] S4. If so, generate a suggestion for adjusting the source position;

[0087] S5. If it does not exist, extract the thermal images collected by multiple infrared cameras and stitch them together to determine the repeated collection area, and determine whether there is a repeated collection area whose area size meets the source specification requirements;

[0088] It should be noted that after determining that the area size of the repeated acquisition area meets the specification requirements of the source causing the source, a simulation is performed after the source causing the source is moved to verify the integrity of the thermal image;

[0089] S6. Generate a suggestion for adjusting the source position: if it exists, select the repeated acquisition area and generate a suggestion for adjusting the source position;

[0090] S7. If not, traverse various combinations of infrared camera acquisition angles to determine whether there is a combination of infrared camera acquisition angles whose size of repeated acquisition areas meets the source specification requirements;

[0091] S8, generating a suggestion for adjusting the source position and the infrared camera angle: if there is, selecting the combination scheme of the plurality of infrared camera acquisition angles and the repeated acquisition area, and generating a suggestion for adjusting the source position and the infrared camera angle;

[0092] S9, if it does not exist, jump to step S2. Through the setting of the scheme adjustment model, based on the layout relationship of multiple infrared cameras, ignition sources, annealing kilns and their related equipment, combined with the actual application of ignition sources, and the actual layout of the company's infrared cameras, intelligent decision-making generates monitoring and adjustment suggestions.
