Description

Technical Field

[0001] This invention relates to roller kilns, and in particular to an energy-saving roller kiln for firing ceramic tiles, applicable to the field of roller kilns. Background Technology

[0002] Roller kilns are continuous sintering equipment widely used in modern ceramics, building materials, and other industries. Their core principle is to transport products via rotating rollers to complete the high-temperature heat treatment process. The core structure of a roller kiln includes the kiln body, feeding platform, discharging platform, main drive system, heating elements, and control system. In actual operation, both the energy loss during flue gas exhaust and the operational impact of opening and closing the kiln doors lead to significant heat loss within the furnace, substantially increasing overall energy consumption.

[0003] To address the aforementioned issues, Chinese invention patent CN115978991A discloses an intelligent energy-saving combustion system specifically for ceramic roller kilns. This system employs forced exhaust waste heat recovery to enhance heat exchange and save significant amounts of fuel. Furthermore, it utilizes interlocking control of natural gas and combustion air to prevent the common problem of large amounts of low-temperature combustion air continuously being blown into the ceramic kiln after the natural gas burner is shut off, thus reducing energy consumption. This system can maintain the kiln temperature for extended periods, further reducing fuel consumption. Additionally, Chinese invention patent application CN117404904A discloses a high-temperature, fast-firing roller kiln for ceramic products and a firing method. This system allows for flexible adjustment of the kiln door height, reducing heat loss and fully utilizing the waste heat from the exhaust gases, making the roller kiln even more energy-efficient and environmentally friendly.

[0004] Although the aforementioned patented technologies have improved the high energy consumption caused by heat loss to some extent, in the actual operation of roller kilns, problems such as nozzle blockage, uneven distribution of combustion air, and disordered flue gas flow can all lead to an imbalance in temperature uniformity in different sections of the kiln. However, due to the high-temperature environment inside the kiln, it is impossible to accurately and effectively monitor the temperature data of different sections of the kiln. As a result, the imbalance in temperature uniformity will not only weaken the firing quality of the tiles, but also increase the defect rate in the production process, thereby reducing the economic efficiency of roller kilns in tile firing. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to monitor and control the uniformity of the temperature in each section of the roller kiln, so as to reduce the risk of temperature imbalance in the kiln.

[0006] To address the aforementioned issues, this invention provides an energy-saving roller kiln for ceramic tile firing, comprising a firing control box, a temperature control system, a furnace body, and a flue gas system installed on the upper side of the furnace body. The firing control box is equipped with a temperature equalization sensing system, which includes a temperature equalization processing unit, a temperature difference status acquisition unit, and a temperature control feedback unit. The exhaust system includes multiple exhaust pipes fixedly installed on the upper part of the furnace body. The outer end of the exhaust pipe is fitted with a waste heat sensing structure. The waste heat sensing structure includes a base plate fixedly connected to the upper part of the furnace body. A temperature-sensing deformation sleeve is fixedly connected to the upper part of the base plate. The temperature-sensing deformation sleeve is filled with temperature-sensing deformation filler.

[0007] In the aforementioned energy-saving roller kiln for ceramic tile firing, the temperature change status of the waste heat of flue gas at different locations can be accurately captured, and the temperature uniformity of each section inside the kiln can be displayed and predicted in real time. This allows for timely and effective temperature control and compensation measures to be implemented inside the kiln, effectively avoiding the risk of temperature imbalance inside the kiln and ensuring the quality of ceramic tile firing inside the kiln.

[0008] As a further improvement of this application, the balancing linkage structure includes a linkage ring fixedly installed at the lower end of the slide plate and sleeved on the outside of the temperature-sensing deformation sleeve. The horizontal sensing structure includes a horizontal sensing sleeve. Both ends of the linkage ring are rotatably connected to linkage ball heads.

Both ends of the counterweight slider are fixedly connected to counterweight guide rods. Both inner walls of the horizontal sensing sleeve are fixedly connected to sensing plates. Both ends of the two sensing plates are fixedly connected to sensing guide rods, and the sensing guide rods cooperate with the counterweight guide rods. The input end of the temperature difference state acquisition unit is independently connected to the sensing guide rods on the left and right sides respectively.

[0009] As a further improvement of this application, both ends of the counterweight slider are fixedly connected with balance springs that are slidably fitted on the outside of the counterweight guide rod. The end of the balance spring away from the counterweight slider is fixedly connected to the sensing plate at the corresponding position, and the balance spring is slidably fitted on the outside of the sensing guide rod.

[0010] As a further improvement of this application, a hinge seat is fixedly connected to the right end of the horizontal sensing sleeve on the right side, and a through-hole hinge joint that mates with the hinge seat is fixedly connected to the left end of the horizontal sensing sleeve on the left side. The two horizontal sensing sleeves between two adjacent exhaust pipes can be rotatably connected through the cooperation of the hinge seat and the through-hole hinge joint.

[0011] As a further improvement of this application, the input end of the equalization temperature sensing processing unit is also connected to a firing parameter setting unit and a temperature control data acquisition unit. The input end of the firing parameter setting unit is connected to the data port signal set on the firing control box, and the input end of the temperature control data acquisition unit is connected to the temperature control system signal.

[0012] As a further improvement of this application, the output of the equalization temperature sensing processing unit is also connected to a monitoring data reflection unit and an abnormality warning unit. The output of the monitoring data reflection unit is connected to the data port signal set on the firing control box, and the output of the abnormality warning unit is connected to the alarm signal set on the firing control box.

[0013] As a further improvement of this application, a heat-insulating elastic sleeve is fixedly connected between the linkage ring and the base plate, and the heat-insulating elastic sleeve is slidably fitted with the heat-sensing deformation sleeve.

[0014] As a further improvement of this application, a plurality of sliding rods located on the outside of the temperature-sensing deformation sleeve are fixedly connected to the upper end of the base plate. The upper end of the sliding rod slides through the trigger sleeve and the slide plate and is fixedly connected to the trigger baffle. The input end of the equalization temperature sensing processing unit is also connected to the waste heat upper limit acquisition unit, and the input end of the waste heat upper limit acquisition unit is connected to the trigger baffle.

[0015] As a further improvement of this application, the lower end of the linkage ring is fixedly connected with multiple sliding sleeves that are fitted on the outside of the corresponding slide rods, and the upper end of the base plate is fixedly connected with multiple temperature-sensing sleeves that are fitted on the outside of the slide rods. The temperature-sensing sleeves cooperate with the trigger sleeves. The input end of the equalization temperature sensing processing unit is also connected to the waste heat lower limit acquisition unit, and the input end of the waste heat lower limit acquisition unit is connected to the temperature-sensing sleeves.

[0016] As a further improvement of this application, the input end of the equalization temperature sensing unit is also connected to a positioning corresponding unit. The input end of the positioning corresponding unit is connected to the data port signal on the firing control box. The output end of the equalization temperature sensing unit is also connected to an independent ignition auxiliary unit. The output end of the independent ignition auxiliary unit is connected to the ignition nozzle system installed on the furnace body through the temperature control system.

[0017] In summary, through the coordinated operation of the balanced temperature sensing system, the waste heat sensing structure, and the horizontal sensing structure, the temperature changes of the waste heat in the flue gas at different locations can be accurately captured. This allows for real-time display and prediction of the temperature uniformity within the furnace, enabling timely and effective temperature control and compensation measures. This effectively avoids the risk of temperature imbalance within the furnace, ensuring the quality of ceramic tile firing and significantly improving the finished product qualification rate. Furthermore, continuous monitoring and analysis of the waste heat data enables accurate prediction and feedback of temperature changes within the furnace, promoting the dynamic balance control of the temperature within the furnace. This not only helps to refine temperature control and reduce the temperature fluctuation range between different sections of the furnace but also significantly reduces energy loss during temperature adjustment, comprehensively improving the economic efficiency of roller kilns in ceramic tile firing.

[0020] The three embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0021] Implementation method 1: Figure 14 The diagram shows an energy-saving roller kiln for ceramic tile firing, comprising a firing control box 1, a temperature control system 2, a furnace body 3, and a flue gas system 4 installed on the upper side of the furnace body 3. Multiple ignition nozzle systems 31 are installed on both the left and right sides of the furnace body 3. The temperature control system 2 is connected to both the ignition nozzle systems 31 and the flue gas system 4, enabling control of the firing temperature within the furnace body 3 and reuse of waste heat from the flue gas. The flue gas system 4 includes multiple flue gas pipes 41 fixedly installed on the upper end of the furnace body 3 and connected to it. The flue gas pipes 41 can draw out the flue gas from the furnace body 3, work with the temperature control system 2 to reuse the waste heat from the flue gas, and subsequently treat and discharge the flue gas.

[0022] It should be noted that the temperature control system 2, ignition nozzle system 31, and exhaust system 4 are all existing components of the roller kiln. These are directly referenced here without any changes to their structure or principle. For example, the temperature control system 2 includes sensors, a controller, a regulating valve assembly, and a safety device. The controller can control the regulating valve assembly based on data feedback from the sensors to achieve temperature control within the furnace body 3. Furthermore, it can cut off the fuel supply via the safety device when the temperature exceeds the limit or when the furnace shuts off. The ignition nozzle system 31 includes nozzle assemblies, a supply pipe, and an ignition device. It can deliver compressed air and natural gas to the mixing chamber in the nozzle assembly via the supply pipe, and then deliver the mixed gas to the nozzle located within the furnace body 3. Simultaneously, the ignition device ignites the mixed gas, achieving a heating effect within the furnace body 3. This system works in conjunction with the temperature control system 2 to promote high-precision coordinated temperature control within the furnace body 3. The flue gas exhaust system 4 includes a main exhaust duct, an exhaust pipe 41 that cooperates with the main exhaust duct, a settling chamber, a dust collector, a bag filter, an induced draft unit, a chimney outlet, and a waste heat conversion structure. It can recover and treat the flue gas within the furnace body 3 to meet emission standards. Furthermore, the waste heat conversion structure recovers and reuses heat from the flue gas. With the cooperation of the temperature control system 2, the waste heat can be effectively utilized within the furnace body 3, thereby effectively reducing energy consumption and increasing efficiency. Those skilled in the art can select appropriate system components based on actual needs; therefore, further details are omitted here.

[0023] The second implementation method: Figure 1 - Figure 13 The diagram shows an energy-saving roller kiln for firing ceramic tiles, including a firing control box 1, a temperature control system 2, a furnace body 3, and a smoke exhaust system 4 installed on the upper side of the furnace body 3. The firing control box 1 is equipped with a temperature equalization sensing system connected to the temperature control system 2. The temperature equalization sensing system includes a temperature equalization processing unit, a temperature difference status acquisition unit connected to the input end of the temperature equalization processing unit, and a temperature control feedback unit connected to the output end of the temperature equalization processing unit. The exhaust system 4 includes multiple exhaust pipes 41 fixedly installed on the upper end of the furnace body 3 and connected to the furnace body 3. The exhaust pipes 41 are fitted with a waste heat sensing structure 5. The waste heat sensing structure 5 includes a base plate 51 fixedly connected to the upper end of the furnace body 3 and fitted on the outside of the corresponding exhaust pipe 41. The upper end of the base plate 51 is fixedly connected to a temperature-sensing deformation sleeve 56. The temperature-sensing deformation sleeve 56 is made of high-temperature resistant elastic materials such as ceramic matrix composite material (silicon carbide fiber toughened silicon carbide (SiC / SiC)) or inorganic non-metallic material (zirconia toughened alumina (ZTA ceramic)). The temperature-sensing deformation sleeve 56 is filled with temperature-sensing deformation filler. The temperature-sensing deformation sleeve 56 is made of corrugated pipe material that generates elastic deformation along its axial direction. The upper end of the temperature-sensing deformation sleeve 56 is fixedly connected to a sliding plate 52. The temperature-sensing deformation sleeve 56 and the sliding plate 52 are slidably fitted on the outside of the exhaust pipe 41. The lower end of the sliding plate 52 is connected to a balance linkage structure 6. The left and right ends of the balanced linkage structure 6 are each equipped with a horizontal sensing structure 7, and two adjacent horizontal sensing structures 7 are connected. The input end of the temperature difference state acquisition unit is connected to the horizontal sensing structure 7, and the output end of the temperature control feedback unit is connected to the temperature control system 2. Through the coordinated operation of the balanced temperature sensing system, the waste heat sensing structure 5, and the horizontal sensing structure 7, the temperature change status of the flue gas waste heat at different locations can be accurately captured, and the temperature uniformity of each section inside the furnace body 3 can be displayed and predicted in real time. This allows for timely and effective temperature control and compensation measures within the furnace body 3, effectively avoiding the risk of temperature uniformity imbalance within the furnace body 3, ensuring the quality of ceramic tile firing within the furnace body 3, and significantly improving the finished product qualification rate. Furthermore, through continuous monitoring and analysis of flue gas waste heat data, accurate prediction and feedback of temperature changes within the furnace body 3 can be achieved, promoting the dynamic balance control of the temperature within the furnace body 3 by the temperature control system 2. This not only helps to refine temperature control and reduce the temperature difference fluctuation range within each section of the furnace body 3, but also significantly reduces energy loss during temperature adjustment, comprehensively improving the economic efficiency of the roller kiln in ceramic tile firing.

[0024] It should be noted that the temperature-sensitive deformation filler can be a temperature-sensitive deformation strip fixedly set on the inner wall of the temperature-sensitive deformation sleeve 56. The temperature-sensitive deformation strip is made of multi-segment deformation memory alloy composite, such as NiTiNb (niobium-modified nickel-titanium alloy), NiTiHf (hafnium-reinforced nickel-titanium alloy), CuAlNiMn (quaternary copper-based alloy) and FeMnSiCr (iron-manganese-silicon-chromium alloy). In order to meet the horizontal sensing between multiple horizontal sensing structures 7, when the temperature-sensitive deformation filler is a temperature-sensitive deformation strip, the appropriate temperature-sensitive deformation strip with a suitable thermal deformation point is selected according to the temperature requirements of different firing stages. The temperature-sensitive deformation filler can also be a thermal expansion gas filled in the temperature-sensitive deformation sleeve 56. The thermal expansion gas can be made from any one of helium, argon, and nitrogen, or the thermal expansion gas can be made from a mixture of helium and argon in a mass ratio of 7:3. In order to meet the horizontal sensing between multiple horizontal sensing structures 7, when the temperature-sensitive deformation filler is a thermal expansion gas, according to the temperature requirements of different firing stages, the thermal expansion gas with different saturation levels can be filled in the temperature-sensitive deformation sleeve 56 at that stage. By setting the temperature-sensitive deformation packing, when the temperature-sensitive deformation sleeve 56 receives the residual heat of the flue gas in the exhaust pipe 41, after the temperature reaches the deformation requirement of the temperature-sensitive deformation packing, the temperature-sensitive deformation sleeve 56 can generate corresponding elongation deformation at different temperatures. In addition, the equalization temperature sensing processing unit can also use the data fed back by the temperature control data acquisition unit to calibrate and verify the status of the temperature-sensitive deformation strip during continuous application, thereby ensuring the accuracy of subsequent temperature state prediction and analysis of each section in the furnace body 3. The output end of the equalization temperature sensing processing unit is also connected to a correction calibration unit, which can display the reset status of each temperature-sensitive deformation sleeve 56 through the horizontal sensing structure 7 when the roller kiln is stopped. This allows the equalization temperature sensing processing unit to correct and calibrate the status of the temperature-sensitive deformation packing in each temperature-sensitive deformation sleeve 56 through the correction calibration unit. When the correction value exceeds the set range, the monitoring data reflection unit and the abnormal warning unit cooperate to display and remind the technicians, prompting the technicians to check, maintain and replace the temperature-sensitive deformation sleeve 56 and the temperature-sensitive deformation packing to ensure the effectiveness of subsequent continuous temperature monitoring and sensing. The temperature-sensing deformation sleeve 56 undergoes corresponding expansion and contraction deformation under the action of the temperature-sensing deformation packing, which in turn drives the slide plate 52 to slide up and down on the outside of the flue pipe 41. This enables the horizontal sensing structures 7 on both sides to tilt accordingly through the balance linkage structure 6. Based on the triggering state of the tilt direction of the horizontal sensing structures 7, the temperature fluctuation state and trend prediction inside the furnace body 3 can be effectively judged. This allows for timely and effective high-precision temperature control inside the furnace body 3, and fine control of specific abnormal temperature sections. This ensures the temperature uniformity of each section inside the furnace body 3 while reducing energy loss during temperature control compensation.

[0025] Figure 2 - Figure 13The diagram shows a balancing linkage structure 6, including a linkage ring 61 fixedly installed at the lower end of a sliding plate 52 and sleeved on the outside of a temperature-sensing deformation sleeve 56. A horizontal sensing structure 7 includes a horizontal sensing sleeve 71. Linkage ball heads 72 are rotatably connected to both ends of the linkage ring 61. The horizontal sensing sleeve 71 is fixedly connected to the end of the linkage ball head 72 furthest from the linkage ring 61. A counterweight slider 73 is slidably disposed inside the horizontal sensing sleeve 71. Counterweight guide rods 731 are fixedly connected to both ends of the counterweight slider 73. Sensing plates 74 are fixedly connected to the inner walls of both sides of the horizontal sensing sleeve 71. Sensing guide rods 741 are fixedly connected to the ends of the two sensing plates 74 closest to each other, and the sensing guide rods 741 cooperate with the counterweight guide rods 731. The input end of the temperature difference state acquisition unit is independently connected to the sensing guide rods 741 on both the left and right sides, respectively. This allows for the acquisition of data from the same exhaust pipe 41. The trigger states within the two horizontal sensing structures 7 are collected and comprehensively judged to effectively acquire the temperature fluctuation status within the furnace body 3. Based on the judgment results, the causes of the fluctuations are analyzed, and high-precision control and compensation data is fed back to the temperature control system 2. This not only improves the accuracy and effectiveness of the temperature control system 2 in controlling the temperature within the furnace body 3, but also effectively reduces the amplitude of temperature fluctuations within the furnace body 3, avoiding the problem of temperature uniformity imbalance in different sections. This effectively ensures the quality of tile firing and promotes the economy of tile firing. Furthermore, based on the analysis and judgment of the causes, the performance of the ignition nozzle system 31 within the furnace body 3 can be analyzed. This reduces the difficulty of maintenance while ensuring the effectiveness of the continuous application of the ignition nozzle system 31, thereby ensuring the effectiveness of temperature control, reducing energy consumption, and promoting the environmental friendliness of the roller kiln in tile firing.

[0026] Figure 3 - Figure 13 The diagram shows that a thermal insulation elastic sleeve 63 is fixedly connected between the linkage ring 61 and the base plate 51, and is fitted onto the outside of the temperature-sensing deformation sleeve 56. The thermal insulation elastic sleeve 63 and the temperature-sensing deformation sleeve 56 are in sliding fit. The thermal insulation elastic sleeve 63 is made of composite material, such as aluminum silicate fiber reinforced rubber composite. The thermal insulation elastic sleeve 63 can effectively insulate and protect the temperature-sensing deformation sleeve 56. While ensuring the thermal deformation of the temperature-sensing deformation sleeve 56, it reduces the heat radiation loss generated by the temperature-sensing deformation sleeve 56 to the outside, thereby promoting the recovery rate of waste heat from flue gas, reducing the waste of heat energy, further promoting the energy-saving and efficiency-enhancing effect of the roller kiln, and promoting the environmental protection of the roller kiln application.

[0027] Figure 3 - Figure 13The counterweight slider 73 is shown to have a balance spring 75 fixedly connected to both ends of the counterweight slider 73 and slidably mounted on the outside of the counterweight guide rod 731. The end of the balance spring 75 away from the counterweight slider 73 is fixedly connected to the corresponding position of the sensing liner 74, and the balance spring 75 is slidably mounted on the outside of the sensing guide rod 741. The balance spring 75 can maintain the position of the counterweight slider 73 evenly and avoid false triggering, thereby ensuring the accuracy of the data obtained by the temperature difference state acquisition unit and promoting the effectiveness of subsequent temperature control in the furnace body 3.

[0028] Figure 3 - Figure 13 The diagram shows a hinge seat 8 fixedly connected to the right end of the horizontal sensing sleeve 71 on the right side, and a through-hole hinge joint 81 fixedly connected to the left end of the horizontal sensing sleeve 71 on the left side, which mates with the hinge seat 8. The through-hole hinge joint 81 has an elongated through hole that mates with the rotating shaft inside the hinge seat 8, thus effectively accommodating angle changes between the two connected horizontal sensing structures 7, avoiding jamming, and ensuring the effectiveness of the linkage between the horizontal sensing structure 7, the balance linkage structure 6, and the waste heat sensing structure 5. The two horizontal sensing sleeves 71 between two adjacent exhaust pipes 41 can be rotatably connected through the cooperation of the hinge seat 8 and the through-hole hinge joint 81. The cooperation of the hinge seat 8 and the through-hole hinge joint 81 can effectively realize the synergistic effect between the two adjacent exhaust pipes 41 through the horizontal sensing structures 7, facilitating the acquisition of temperature fluctuation data of each section inside the furnace body 3 by the temperature difference state acquisition unit, and playing a role in real-time monitoring of the temperature data inside the furnace body 3.

[0029] Figure 2 The input terminal of the equalization temperature sensing unit is also connected to a firing parameter setting unit and a temperature control data acquisition unit. The input terminal of the firing parameter setting unit is connected to the data port on the firing control box 1, and the input terminal of the temperature control data acquisition unit is connected to the temperature control system 2. The setting of the firing parameter setting unit and the temperature control data acquisition unit can help the equalization temperature sensing unit effectively acquire the process parameters and actual temperature data of the furnace body 3, and improve the accuracy of its subsequent prediction and judgment of flue gas waste heat data acquisition, thereby ensuring the effectiveness of subsequent temperature control compensation.

[0030] The data port of the firing control box 1 can connect to devices for data command input, including but not limited to keyboards, mice, buttons, touch screens, and USB ports. Technicians input relevant process parameters for ceramic tile firing in the roller kiln into the firing parameter setting unit through the data port. These process parameters include firing segments, temperature control range of each segment, ceramic tile firing and transport speed, relevant rated operating data of the temperature control system 2, relevant rated operating data of the ignition nozzle system 31, rated operating data of the exhaust system 4, and the heat loss rate of flue gas transmitted from the roller kiln to the exhaust pipe 41. The firing parameter setting unit converts these process parameters and transmits them to the equalization temperature sensing and processing unit. The equalization temperature sensing and processing unit can process, analyze, and subsequently control these data. During the operation of the roller kiln, the temperature control system 2 controls the temperature inside the furnace body 3 according to the range set by the process parameters. The temperature control data acquisition unit can collect and acquire the temperature control data of the temperature control system 2, and then transmit the data to the equalization temperature sensing processing unit. This allows the equalization temperature sensing processing unit to judge the temperature control process and status of the temperature control system 2 based on the acquired data. In the future, when temperature adjustment and compensation are required, it can generate high-precision and effective data feedback to ensure the effectiveness of its temperature equalization control inside the furnace body 3.

[0031] Figure 2 The output of the equalization temperature sensing unit is also connected to a monitoring data reflection unit and an abnormality warning unit. The output of the monitoring data reflection unit is connected to the data port signal on the firing control box 1, and the output of the abnormality warning unit is connected to the alarm signal on the firing control box 1. The setting of the monitoring data reflection unit and the abnormality warning unit can promote the interaction of the equalization temperature sensing system, and can promptly display and remind technicians of the predicted data, so that technicians can adjust the process parameters according to the predicted data and ensure the quality stability of the roller kiln for ceramic tile firing.

[0032] The data port of the firing control box 1 can also be connected to devices for data display, including but not limited to displays, memory, and PCs. The equalization temperature sensing and processing unit can monitor and predict the temperature status inside the furnace body 3, as well as the subsequent temperature feedback and control. All of this is displayed to technicians through the monitoring data feedback unit and the data port, enabling technicians to obtain timely information on the temperature changes inside the furnace body 3 during the firing of tiles in the roller kiln. This allows for effective adjustment of the tile firing parameters, improving the quality and efficiency of tile firing. Furthermore, when abnormal temperatures occur and control is ineffective, the alarm can be activated through the abnormality warning unit. While issuing an alarm, technicians can also effectively determine the location of the abnormality based on the reflected data, assisting them in analyzing the causes of the abnormality and improving the efficiency of abnormality handling. This reduces the impact on the quality of tile firing and ensures the economic benefits of firing tiles in the roller kiln.

[0033] Figure 1 - Figure 13 As the temperature control system 2 continuously controls the temperature inside the furnace body 3 during the firing of ceramic tiles in the roller kiln, the temperature inside the furnace body 3 rises continuously. When the exhaust system 4 collects the flue gas inside the furnace body 3 through the exhaust pipe 41, the flue gas flowing through the exhaust pipe 41 carries a large amount of heat energy. The heat energy acts on the temperature-sensing deformation sleeve 56 through the wall of the exhaust pipe 41, causing the temperature-sensing deformation packing in the temperature-sensing deformation sleeve 56 to undergo corresponding elongation deformation under the action of the residual heat of the flue gas. This, in turn, drives the sliding plate 52 and the balance linkage structure 6 to move upward under the guidance of the sliding rod 53.

[0034] When the temperature-sensing deformation sleeves 56 located on multiple exhaust pipes 41 rise to the same height, the two horizontal sensing structures 7 between two adjacent exhaust pipes 41, through the connection of the hinge seat 8 and the through-hole hinge joint 81, maintain a horizontal state. This causes the horizontal sensing structures 7 on both sides of the same exhaust pipe 41 to remain horizontal. Consequently, the counterweight slider 73 located inside the horizontal sensing sleeve 71, under the action of gravity balance and the balance spring 75, is positioned in the middle of the horizontal sensing sleeve 71. Therefore, it will not generate any contact or triggering through the counterweight guide rod 731 against the sensing guide rod 741, maintaining a constant open state. At this time, the equalization temperature sensing processing unit can receive the non-triggered signal data transmitted by the temperature difference state acquisition unit. Therefore, based on the state of residual heat of the flue gas in the exhaust pipe 41, it can effectively determine that the temperature uniformity of each section in the furnace body 3 is good. Therefore, no adjustment or compensation is required, and the data is only displayed by the monitoring data reflection unit.

[0035] When the elongation deformation range of the temperature-sensing deformation sleeve 56 on the outside of a smoke exhaust pipe 41 is small, the height of its upper sliding plate 52 is lower than the height of the sliding plates 52 on the left and right sides. Therefore, the two horizontal sensing structures 7 between two adjacent smoke exhaust pipes 41 form an inwardly inclined state through the connection of the hinge seat 8 and the through-hole hinge joint 81. This causes the horizontal sensing structures 7 on the left and right sides of the smoke exhaust pipe 41 to tilt towards the direction of the smoke exhaust pipe 41. Consequently, the counterweight slider 73 located in the horizontal sensing sleeve 71 will move towards the direction of the smoke exhaust pipe 41 under the action of gravity, causing the corresponding balance spring 75 to contract. That is, the counterweight slider 73 on the left side moves to the right, and the counterweight guide rod 731 abuts against the sensing guide rod 741 on its right side. The counterweight slider 73 on the right side moves to the left, and the counterweight... The guide rod 731 abuts against the sensing guide rod 741 located to its left, thereby generating a double proximity trigger signal on the horizontal sensing structures 7 on both sides of the same exhaust pipe 41. The temperature difference state acquisition unit transmits the double proximity trigger signal to the equalization temperature sensing processing unit. The equalization temperature sensing processing unit determines that the temperature uniformity in the furnace body 3 located in the section of the exhaust pipe 41 is at risk of being abnormal and the temperature is low. Then, it transmits temperature adjustment and compensation data for that section to the temperature control system 2 through the temperature control feedback unit. The temperature control system 2 performs precise temperature control on the furnace body 3 based on the feedback data. For example, it may shorten the intermittent operation interval or increase the efficiency of the ignition nozzle system 31 at that individual position, or enhance the wind force towards that section to promote the temperature uniformity in the furnace body 3, thereby eliminating the abnormal temperature uniformity in that section of the furnace body 3 and ensuring the quality of ceramic firing.

[0036] When the elongation deformation range of the temperature-sensing deformation sleeves 56 on the outer sides of multiple exhaust pipes 41 gradually decreases in a certain direction, which is set to gradually decrease from left to right, the height of the right-side slide plate 52 will gradually be lower than the height of its adjacent left-side slide plate 52. Therefore, the multiple horizontal sensing structures 7 connected by the hinge seat 8 and the through-hole hinge joint 81 will form a tilted state towards the right. That is, the horizontal sensing structures 7 on the left and right sides of the same exhaust pipe 41 will produce parallel tilting effects. Consequently, the counterweight slider 73 inside the horizontal sensing sleeve 71 will move to the right under the action of gravity, causing the corresponding balance spring 75 to contract and deform. That is, the counterweight slider 73 on the left side will move to the right, and the counterweight guide rod 731 will abut against the sensing guide rod 741 on its right side. The counterweight slider 73 on the side moves synchronously to the right, and the counterweight guide rod 731 abuts against the sensing guide rod 741 located on its right, thereby generating a double-directional trigger signal on the horizontal sensing structures 7 on both sides of the same exhaust pipe 41. The temperature difference state acquisition unit transmits the double-directional trigger signal to the equalization temperature sensing processing unit. The equalization temperature sensing processing unit determines that there is a risk of temperature control abnormality in the furnace body 3 at this position, and then transmits the temperature regulation compensation data of this position to the temperature control system 2 through the temperature feedback unit. The temperature control system 2 accurately regulates the temperature in the furnace body 3 according to the feedback data, such as raising the overall temperature of the furnace body 3 at this position to ensure the effectiveness of the firing temperature in the furnace body 3, avoid quality abnormalities caused by excessively low firing temperature, promote the yield of ceramic tiles fired in the roller kiln, and improve economic efficiency.

[0037] When the elongation deformation range of the temperature-sensing deformation sleeve 56 on the outside of a smoke exhaust pipe 41 is large, the height of its upper sliding plate 52 is higher than the height of the sliding plates 52 on the left and right sides. Therefore, the two horizontal sensing structures 7 between two adjacent smoke exhaust pipes 41 form an inwardly convex inclined state through the connection of the hinge seat 8 and the through-hole hinge joint 81. This causes the horizontal sensing structures 7 on the left and right sides of the smoke exhaust pipe 41 to tilt away from the smoke exhaust pipe 41. Consequently, the counterweight slider 73 inside the horizontal sensing sleeve 71 will move away from the smoke exhaust pipe 41 under the action of gravity, causing the corresponding balance spring 75 to contract. That is, the counterweight slider 73 on the left side moves to the left, and the counterweight guide rod 731 abuts against the sensing guide rod 741 on its left side, triggering the counterweight slider 73 on the right side to contract. The furnace moves to the right, triggering the induction guide rod 741 located to its right by the counterweight guide rod 731. This causes the horizontal induction structures 7 on both sides of the same exhaust pipe 41 to generate a double-distance trigger signal. The temperature difference acquisition unit transmits the double-distance trigger signal to the equalization temperature processing unit. The equalization temperature processing unit determines that the temperature uniformity within the furnace body 3 located in this section of the exhaust pipe 41 is at risk of being abnormal and that the temperature is too high. It then transmits temperature adjustment and compensation data for this section to the temperature control system 2 through the temperature control feedback unit. The temperature control system 2 performs precise temperature control on the furnace body 3 based on the feedback data, such as controlling the ignition nozzle system 31 at this individual position to pause ignition or reduce its efficiency. While ensuring the temperature uniformity of each section within the furnace body 3, it can also effectively reduce energy consumption during the operation of the roller kiln and lower energy costs.

[0038] After the temperature control system 2 is regulated and compensated by the temperature control feedback unit, the temperature control processing unit can monitor the heat status of the flue gas entering the flue gas pipe 41 in the adjusted furnace body 3 through the temperature difference status acquisition unit. This allows the unit to verify the regulation and compensation effect. If the verification is effective, the regulation effect is maintained. If the verification effect is poor, the abnormality warning unit is activated to remind technicians to handle the abnormal temperature control.

[0039] The third implementation method: Figure 1 - Figure 13The diagram shows an energy-saving roller kiln for ceramic tile firing. Multiple sliding rods 53 are fixedly connected to the upper end of the base plate 51, located outside the temperature-sensing deformation sleeve 56. The upper ends of the sliding rods 53 slide through the trigger sleeve 62 and the sliding plate 52, and are fixedly connected to a trigger baffle 55. The input end of the equalization temperature sensing processing unit is also connected to a waste heat upper limit acquisition unit. The input end of the waste heat upper limit acquisition unit is connected to the trigger baffle 55. The cooperation between the waste heat upper limit acquisition unit and the trigger baffle 55 enables effective sensing and triggering of waste heat in each section of flue gas. This facilitates the subsequent temperature control feedback unit to transmit temperature regulation and compensation parameters to the temperature control system 2, reducing the temperature inside the furnace body 3, reducing fuel consumption, and thus achieving effective energy saving.

[0040] Figure 2 - Figure 11 The lower end of the linkage ring 61 is fixedly connected to multiple trigger sleeves 62 that slide and are fitted onto the outside of the corresponding slide rods 53. The upper end of the base plate 51 is fixedly connected to multiple temperature-sensing contact sleeves 54 that are fitted onto the outside of the slide rods 53. The temperature-sensing contact sleeves 54 cooperate with the trigger sleeves 62. The input end of the equalization temperature sensing processing unit is also connected to the waste heat lower limit acquisition unit. The input end of the waste heat lower limit acquisition unit is connected to the temperature-sensing contact sleeves 54. The cooperation between the waste heat lower limit acquisition unit and the temperature-sensing contact sleeves 54 can effectively sense and trigger the display of waste heat in each section of flue gas. This facilitates the subsequent temperature control feedback unit to transmit temperature regulation compensation parameters to the temperature control system 2, and timely increases the temperature inside the furnace body 3 to ensure the effect and quality of ceramic tile firing. Furthermore, with the cooperation of the waste heat upper limit acquisition unit, the risk of temperature imbalance in the furnace body 3 caused by exceeding the temperature limit in this section can be effectively avoided. This promotes the refinement of temperature control, reduces the temperature difference fluctuation range in each section of the furnace body 3, and thus effectively promotes the economic efficiency of roller kiln application.

[0041] Figure 1 and Figure 2 The input of the equalization temperature sensing unit is connected to a positioning and corresponding unit. The input of the positioning and corresponding unit is connected to a data port on the firing control box 1. The output of the equalization temperature sensing unit is connected to an independent ignition auxiliary unit. The output of the independent ignition auxiliary unit is connected to the ignition nozzle system 31 installed on the furnace body 3 through the temperature control system 2. With the cooperation of the positioning and corresponding unit and the independent ignition auxiliary unit, when the temperature data in the furnace body 3 fluctuates, the equalization temperature sensing unit can be assisted in verifying the cause of the abnormality. This reduces the difficulty of monitoring and maintaining the status of the ignition nozzle system 31 and effectively promotes the accuracy and effectiveness of the subsequent temperature control feedback unit in generating adjustment and compensation data for the temperature control system 2.

[0042] It should be noted that the technicians input the number and corresponding position data of the ignition nozzle system 31 and the flue gas pipe 41 set on the actual roller kiln to the positioning unit through the data port. The positioning unit processes and converts the received data and then transmits it to the equalization temperature sensing unit. This enables the equalization temperature sensing unit to control the ignition nozzle system 31 near the flue gas pipe 41 where an abnormal temperature occurs, and to verify the cause of the abnormality.

[0043] Figure 1 - Figure 13 The diagram shows that while the temperature state inside the furnace body 3 is predicted by the flue gas heat state fed back by the temperature difference state acquisition unit through the equalization temperature sensing processing unit, the slide plate 52 moves up and down under the thermal deformation of the temperature sensing deformation sleeve 56, and at the same time drives the linkage ring 61 to move synchronously. As the slide plate 52 moves upward until it comes into contact with the trigger baffle 55, the waste heat upper limit acquisition unit can acquire the trigger data and transmit the upper limit trigger data to the equalization temperature sensing processing unit. The equalization temperature sensing processing unit judges the overall temperature state inside the furnace body 3 based on the number of trigger baffles 55 that are triggered. When the number of trigger baffles 55 that are triggered is greater than one-third, it means that the overall temperature inside the furnace body 3 is at the upper limit of the temperature control, which is a high state. Then, the temperature control feedback unit sends a regulation and compensation signal to the temperature control system 2, so that the temperature control system 2 can control the overall temperature inside the furnace body 3. This ensures the firing quality of the tiles and effectively reduces energy consumption during the firing process. When the number of trigger baffles 55 that are triggered is less than or equal to one-third, the temperature difference state acquisition unit sends a regulation and compensation signal to the temperature control system 2 through the temperature control feedback unit to regulate and maintain the uniformity of the temperature inside the furnace body 3, thereby avoiding poor tile firing caused by temperature differences in different sections. When the sliding plate 52 drives the linkage ring 61 to move downwards until the trigger sleeve 62 comes into contact with the temperature sensing sleeve 54, the residual heat lower limit acquisition unit can acquire the trigger data and transmit the lower limit trigger data to the equalization temperature sensing processing unit. The equalization temperature sensing processing unit judges the overall temperature state inside the furnace body 3 based on the number of temperature sensing sleeves 54 that are triggered. When the number of temperature sensing sleeves 54 that are triggered is greater than one-third, it means that the overall temperature inside the furnace body 3 is at the lower limit of temperature control and is in a low state. Then, the temperature control feedback unit sends a regulation and compensation signal to the temperature control system 2, so that the temperature control system 2 can control the overall temperature inside the furnace body 3 to ensure the quality and efficiency of tile firing. When the number of temperature sensing sleeves 54 that are triggered is less than or equal to one-third, the temperature control feedback unit sends a regulation and compensation action to the temperature control system 2 based on the data transmitted by the temperature difference state acquisition unit, so as to regulate and maintain the uniformity of temperature inside the furnace body 3, thereby avoiding poor tile firing problems caused by temperature differences in different sections.

[0044] When the equalization temperature sensing processing unit determines that the furnace body 3 has a risk of abnormal temperature uniformity based on the dual proximity trigger signal transmitted by the temperature difference status acquisition unit or the lower limit trigger data transmitted by the waste heat lower limit acquisition unit, the equalization temperature sensing processing unit determines the corresponding ignition nozzle system 31 in the abnormal segment based on the position data of the exhaust pipe 41 and the ignition nozzle system 31 transmitted by the positioning corresponding unit. Then, it uses the independent ignition auxiliary unit to adjust the ignition nozzle system 31, generating a corresponding adjustment command to increase efficiency. Then, it follows the subsequent temperature difference status acquisition unit or waste heat... The data fed back by the lower limit acquisition unit is used to determine the effect of the control on the ignition nozzle system 31. When the control on the ignition nozzle system 31 is determined to be effective, the monitoring data feedback unit will show the technicians the abnormal performance of the ignition nozzle system 31 in that section. There may be abnormalities such as burner carbon buildup, which require maintenance. This will help the technicians determine the cause of the temperature control abnormality. At the same time, the temperature control feedback unit will transmit the control parameters of the ignition nozzle system 31 to the temperature control system 2, so that the temperature control system 2 can modify the control parameters of the ignition nozzle system 31 in a timely manner. If the control effect of the ignition nozzle system 31 is deemed ineffective, the control compensation data will be transmitted to the temperature control system 2 through the temperature control feedback unit. This will enable the temperature control system 2 to perform corresponding temperature control on the furnace section 3 and transmit the verified data to the technicians through the monitoring data feedback unit. This will allow the technicians to determine the cause of the abnormal temperature uniformity in the section, thereby promoting the subsequent adjustment of process parameters by the technicians and improving the firing quality and control accuracy of the roller kiln in continuous application.

[0045] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
