TECHNICAL FIELD

[0001] The present application relates to a roller kiln, in particular to an energy-saving ceramic tile firing roller kiln applied in the field of roller kiln. BACKGROUND

[0002] The roller kiln is a continuous sintering equipment widely used in modern ceramic, building material and other industries, and its core principle is to complete the high-temperature heat treatment process by rotating roller bars to convey the products. The core structure of the roller kiln includes a kiln body, a feeding table, a discharging table, a main transmission system, heating elements and a control system. In actual operation, the energy loss in the exhaust process and the operation influence when opening and closing the door of the kiln will cause a large amount of heat loss in the kiln, significantly increasing the overall energy consumption.

[0003] In view of the above problems, Chinese patent CN115978991A discloses an intelligent energy-saving combustion system special for ceramic roller kiln, which adopts forced exhaust heat recovery mode to enhance heat exchange effect and save a large amount of fuel. Moreover, natural gas and combustion air interlocking control are adopted to eliminate the phenomenon that a large amount of low-temperature combustion air is continuously blown into the ceramic kiln after the natural gas burner is turned off, thereby causing energy consumption to increase. The kiln temperature can be maintained for a long time, and fuel consumption will be further reduced. In addition, Chinese patent application CN117404904A discloses a ceramic product high-temperature fast firing roller kiln and firing method, which can flexibly adjust the height of the kiln door to reduce heat loss and fully utilize the waste heat of exhaust gas, so that the roller kiln is more energy-saving and environmentally friendly.

[0004] Although the foregoing patent technologies have improved the high energy consumption caused by heat loss to some extent, in actual operation of the roller kiln, problems such as nozzle blockage, uneven distribution of combustion air and disorderly flow of flue gas can cause imbalance of temperature uniformity in each section of the kiln. However, due to the high-temperature environment in the kiln, the temperature data in each section of the kiln cannot be accurately and effectively monitored, and in the case of imbalance of temperature uniformity, not only the firing quality of the ceramic tile will be weakened, but also the defective rate in the production process will be increased, thereby weakening the economic efficiency of the roller kiln in the firing of ceramic tiles.

DETAILED DESCRIPTION

[0036] The three embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0037] First embodiment:

[0038] Figure 14 An energy-saving ceramic tile firing roller kiln is shown, which comprises a firing control box 1, a temperature control system 2, a furnace body 3 and an exhaust system 4 installed on the upper side of the furnace body 3. A plurality of ignition nozzle systems 31 are installed on both sides of the furnace body 3. The temperature control system 2 is connected to the ignition nozzle systems 31 and the exhaust system 4, which can control the firing temperature in the furnace body 3 and reuse the exhaust heat. The exhaust system 4 comprises a plurality of 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 can lead the flue gas in the furnace body 3 out, reuse the exhaust heat with the temperature control system 2, and treat and discharge the flue gas subsequently.

[0039] It should be noted that the temperature control system 2, the ignition nozzle system 31 and the exhaust system 4 are all existing components of the roller kiln, which are directly quoted here without any changes to their structure and principle. For example, the temperature control system 2 includes sensors, controllers, regulating valve groups and safety devices. The controller can control the regulating valve group according to the data fed back by the sensors to achieve temperature control in the furnace body 3, and can also control through the safety device when the temperature exceeds the limit or goes out, cutting off the fuel supply. The ignition nozzle system 31 includes nozzle assemblies, supply pipelines and ignition devices, which can deliver compressed air and natural gas to the mixing chamber in the nozzle assembly through the supply pipeline, then deliver the mixed gas to the nozzle located in the furnace body 3, and ignite the mixed gas with the ignition device to achieve the warming effect in the furnace body 3. It can cooperate with the temperature control system 2 to promote high-precision collaborative regulation of the temperature in the furnace body 3. The exhaust system 4 includes a main exhaust pipeline, an exhaust pipe 41 cooperating with the main exhaust pipeline, a settling chamber, a dust collector, a bag filter, an induced draft unit, a chimney discharge port and a waste heat conversion structure. It can recycle and treat the flue gas in the furnace body 3 to meet the emission standard, and recycle and reuse the heat in the flue gas using the waste heat conversion structure. Through the cooperation of the temperature control system 2, the waste heat can be effectively applied in the furnace body 3, thereby achieving the effect of effectively reducing energy consumption and increasing efficiency. Those skilled in the art can select the above system components according to actual needs, so this place does not make too much repetition.

[0040] Second embodiment:

[0041] Figure 1 Figure 13 An energy-saving ceramic tile firing roller kiln is shown, which includes a firing control box 1, a temperature control system 2, a furnace body 3 and an exhaust system 4 installed on the upper side of the furnace body 3. The firing control box 1 is equipped with a balanced temperature sensing system connected to the temperature control system 2. The balanced temperature sensing system includes a balanced temperature sensing processing unit, a temperature difference state acquisition unit connected to the input end of the balanced temperature sensing processing unit, and a temperature control feedback unit connected to the output end of the balanced temperature sensing processing unit.

[0042] ​The smoke exhaust system 4 comprises a plurality of smoke exhaust pipes 41 fixedly installed on the upper end of the furnace body 3 and connected with the furnace body 3, and a waste heat induction structure 5 is sleeved on the outer end of the smoke exhaust pipe 41. The waste heat induction structure 5 comprises a bottom plate 51 fixedly connected to the upper end of the furnace body 3 and sleeved on the outer side of the corresponding smoke exhaust pipe 41, a temperature-sensitive deformation sleeve 56 fixedly connected to the upper end of the bottom plate 51, the temperature-sensitive deformation sleeve 56 being made of a high-temperature-resistant elastic material such as ceramic matrix composite (silicon carbide fiber toughened silicon carbide (SiC / SiC)) or inorganic non-metallic material (zirconia toughened alumina (ZTA ceramic)), a temperature-sensitive deformation filler is arranged in the temperature-sensitive deformation sleeve 56, and the temperature-sensitive deformation sleeve 56 is made of a bellows material that can elastically deform along the axial direction, the upper end of the temperature-sensitive deformation sleeve 56 is fixedly connected to a sliding plate 52, and the temperature-sensitive deformation sleeve 56 and the sliding plate 52 are both sleeved on the outer side of the smoke exhaust pipe 41, and the lower end of the sliding plate 52 is connected to a balance linkage structure 6.

[0043] The balance linkage structure 6 is rotatably installed with a horizontal induction structure 7 at the left and right ends, and adjacent two horizontal induction structures 7 are connected, the input end of the temperature difference state acquisition unit is connected with the horizontal induction structure 7, and the output end of the temperature control feedback unit is connected with the temperature control system 2. Through the coordinated operation of the balance temperature sensing system, the waste heat induction structure 5 and the horizontal induction structure 7, the temperature change state of the waste heat of flue gas at different positions can be accurately captured, the temperature uniformity of each section inside the furnace body 3 can be displayed and predicted in real time, and the temperature inside the furnace body 3 can be timely and effectively regulated and compensated, thereby avoiding the risk of imbalance of the temperature uniformity inside the furnace body 3, ensuring the quality of the ceramic tile firing inside the furnace body 3, significantly improving the qualified rate of the finished product, and through continuous monitoring and analysis of the waste heat data of flue gas, accurate prediction and feedback of the temperature change inside the furnace body 3 are realized, promoting the dynamic balance regulation and control of the temperature control system 2 on the temperature inside the furnace body 3, which not only helps to promote the refinement of temperature regulation and reduce the temperature difference fluctuation range of each section inside the furnace body 3, but also greatly reduces the energy loss in the temperature regulation process, and comprehensively improves the economic efficiency of the roller kiln in the ceramic tile firing aspect.

[0044] It should be noted that the temperature-sensitive deformation filler can be a temperature-sensitive deformation strip fixedly arranged on the inner wall of the temperature-sensitive deformation sleeve 56, and the temperature-sensitive deformation strip is made of a multi-section type shape memory alloy composite, such as NiTiNb (niobium modified nickel-titanium alloy), NiTiHf (hafnium enhanced nickel-titanium alloy), CuAlNiMn (four-element copper-based alloy), and FeMnSiCr (iron-manganese-silicon-chromium alloy), and in order to meet the horizontal induction between the plurality of horizontal induction structures 7, when the temperature-sensitive deformation filler is the temperature-sensitive deformation strip, the temperature-sensitive deformation strip with a suitable thermal deformation point is selected according to the temperature requirement of different firing stages;

[0045] The temperature-sensitive deformation filler can also be a thermal expansion gas filled in the temperature-sensitive deformation sleeve 56, the thermal expansion gas being made of any one of helium, argon, and nitrogen, or the thermal expansion gas being a mixture of helium and argon in a mass mixing ratio of 7:3. In order to satisfy the horizontal sensing between the multiple horizontal sensing structures 7, when the temperature-sensitive deformation filler is the thermal expansion gas, different degrees of saturation of the thermal expansion gas are selected to be filled in the temperature-sensitive deformation sleeve 56 according to the temperature requirements of different firing stages.

[0046] Through the arrangement of the temperature-sensitive deformation filler, when the temperature-sensitive deformation sleeve 56 receives the flue gas waste heat in the flue gas duct 41, the temperature-sensitive deformation sleeve 56 can generate corresponding elongation deformation at different temperatures after the temperature reaches the deformation requirement of the temperature-sensitive deformation filler. The temperature balancing processing unit can also calibrate and verify the state of the temperature-sensitive deformation strip during the continuous application process according to the feedback data of the temperature control data acquisition unit, so as to ensure the accuracy of the subsequent prediction and analysis of the temperature state of each section of the furnace body 3. The output end of the temperature balancing processing unit is also connected to a correction and calibration unit. When the roller kiln is stopped, the resetting conditions of each temperature-sensitive deformation sleeve 56 can be displayed through the horizontal sensing structure 7, so that the temperature balancing processing unit can correct and calibrate the state of the temperature-sensitive deformation filler in each temperature-sensitive deformation sleeve 56 through the correction and calibration unit. When the correction value exceeds the set range, the technical personnel are displayed and reminded through the cooperation of the monitoring data reflection unit and the abnormal warning unit, so as to prompt the technical personnel to check, maintain, and replace the temperature-sensitive deformation sleeve 56 and the temperature-sensitive deformation filler, thereby ensuring the effectiveness of the subsequent continuous temperature monitoring and sensing.

[0047] The temperature-sensitive deformation sleeve 56 generates corresponding expansion and contraction deformation under the action of the temperature-sensitive deformation filler, which in turn drives the sliding plate 52 to slide up and down outside the flue gas duct 41. The balance linkage structure 6 drives the left and right horizontal sensing structures 7 to generate corresponding inclination changes. According to the triggering state of the inclination direction of the horizontal sensing structure 7, the fluctuation state and trend prediction of the temperature in the furnace body 3 can be effectively determined. The temperature in the furnace body 3 can be timely and effectively controlled with high precision. The specific temperature abnormal section is controlled in detail. In this way, while ensuring the uniformity of the temperature of each section of the furnace body 3, the energy loss in the temperature control compensation process can also be reduced.

[0048] Figure 2 - Figure 13The balance linkage structure 6 comprises a linkage ring 61 fixedly installed at the lower end of the sliding plate 52 and sleeved outside the temperature-sensitive deformation sleeve 56, the horizontal sensing structure 7 comprises a horizontal sensing sleeve 71, the left and right ends of the linkage ring 61 are rotationally connected with linkage ball heads 72, the end of the linkage ball head 72 away from the linkage ring 61 is fixedly connected with the horizontal sensing sleeve 71, a counterweight sliding block 73 is slidably arranged in the horizontal sensing sleeve 71, the left and right ends of the counterweight sliding block 73 are fixedly connected with counterweight guide rods 731, the left and right inner walls of the horizontal sensing sleeve 71 are fixedly connected with sensing lining plates 74, the left and right ends of the two sensing lining plates 74 are fixedly connected with sensing guide rods 741, and the sensing guide rods 741 are matched with the counterweight guide rods 731, the input ends of the temperature difference state acquisition unit are independently connected with the sensing guide rods 741 on the left and right sides, the trigger states in the left and right horizontal sensing structures 7 on the same smoke exhaust pipe 41 are collected and comprehensively judged, so that the state of temperature fluctuation in the furnace body 3 is effectively obtained, the fluctuation causes can be analyzed according to the judgment result, high-precision control compensation data is fed back to the temperature control system 2, the precision and effect of the temperature control system 2 on the temperature control in the furnace body 3 are promoted, the temperature fluctuation amplitude in the furnace body 3 is effectively reduced, the problem of imbalance of temperature uniformity in each section is avoided, the quality of ceramic tile firing is effectively ensured, the economy of ceramic tile firing is promoted, and the performance of the ignition nozzle system 31 in the furnace body 3 can be analyzed according to the analysis and judgment of the causes, so that the maintenance difficulty is reduced, the effectiveness of the continuous application of the ignition nozzle system 31 is ensured, the effectiveness of temperature control is ensured, energy loss is reduced, and the environmental friendliness of the roller kiln for ceramic tile firing is promoted.

[0049] Figure 3 - Figure 13 The linkage ring 61 and the bottom plate 51 are fixedly connected with a temperature insulation elastic sleeve 63 sleeved outside the temperature-sensitive deformation sleeve 56, and the temperature insulation elastic sleeve 63 is in sliding cooperation with the temperature-sensitive deformation sleeve 56, the temperature insulation elastic sleeve 63 is made of a composite material, for example, an aluminum silicate fiber reinforced rubber composite, the temperature insulation elastic sleeve 63 can effectively protect the temperature-sensitive deformation sleeve 56 from temperature insulation, while ensuring the heating deformation of the temperature-sensitive deformation sleeve 56, reducing the heat radiation loss of the temperature-sensitive deformation sleeve 56 to the outside, thereby promoting the recovery rate of the subsequent smoke waste heat recovery, reducing the waste of heat energy, further promoting the energy saving and efficiency of the roller kiln, and promoting the environmental friendliness of the roller kiln application.

[0050] Figure 3 - Figure 13The counterweight sliding block 73 is fixedly connected with a balance spring 75 slidingly sleeved outside the counterweight guide rod 731 at both ends. The balance spring 75 is fixedly connected with the corresponding inductive lining plate 74 at the end away from the counterweight sliding block 73, and is slidingly sleeved outside the inductive guide rod 741. The balance spring 75 can balance the position of the counterweight sliding block 73, avoid accidental triggering, ensure the accuracy of the data obtained by the temperature difference state acquisition unit, and promote the effectiveness of subsequent temperature regulation in the furnace body 3.

[0051] Figure 3 - Figure 13 The right end of the right horizontal induction sleeve 71 is fixedly connected with a hinge seat 8, and the left end of the left horizontal induction sleeve 71 is fixedly connected with a through-hole hinge joint 81 matched with the hinge seat 8. A long through-hole matched with the rotating shaft in the hinge seat 8 is formed in the through-hole hinge joint 81, which can effectively adapt to the angle change between the two connected horizontal induction structures 7, avoid jamming, ensure the effectiveness of the linkage action of the horizontal induction structure 7, the balance linkage structure 6 and the waste heat induction structure 5, and realize the rotary connection between the two horizontal induction sleeves 71 between the adjacent two smoke exhaust pipes 41.

[0052] Figure 2 The input end of the balanced temperature sensing processing unit is also connected with a firing parameter setting unit and a temperature control data acquisition unit. The input end of the firing parameter setting unit is signal connected with the data port on the firing control box 1, and the input end of the temperature control data acquisition unit is signal connected with the temperature control system 2. The setting of the firing parameter setting unit and the temperature control data acquisition unit can promote the balanced temperature sensing processing unit to effectively obtain the process parameters and actual temperature data of the furnace body 3, promote the accuracy of subsequent prediction and judgment of flue gas waste heat data acquisition, and ensure the effectiveness of subsequent temperature regulation compensation.

[0053] The data port of the firing control box 1 can be connected to devices for data instruction input, including but not limited to keyboard, mouse, key, touch screen, USB port, etc. The technician inputs the relevant process parameters of the roller kiln for firing the ceramic tile into the firing parameter setting unit through the data port, which includes firing segmentation, temperature control range of each segment, ceramic tile firing transport speed, relevant rated operation data of the temperature control system 2, relevant rated operation data of the ignition nozzle system 31, relevant rated operation data of the exhaust system 4, and the heat loss rate of the flue gas transported by the roller kiln into the exhaust pipe 41, etc. The firing parameter setting unit converts and transmits these process parameters to the balanced temperature sensing processing unit. The balanced temperature sensing processing unit can process, analyze and apply control to these data. During the operation of the roller kiln, the temperature in the furnace body 3 is controlled according to the range set by the process parameters through the temperature control system 2. The temperature control data acquisition unit can acquire and obtain the temperature control data of the temperature control system 2, and then transmit the data to the balanced temperature sensing processing unit, so that the balanced temperature sensing processing unit can judge the temperature control process and state of the temperature control system 2 according to the obtained data, and then generate high-precision and effective data feedback when subsequent temperature regulation compensation is needed, to ensure the effectiveness of the temperature balance regulation of the furnace body 3.

[0054] Figure 2 The output end of the balanced temperature sensing processing unit is also connected to the monitoring data reflection unit and the abnormal warning unit. The output end of the monitoring data reflection unit is signal connected to the data port provided on the firing control box 1, and the output end of the abnormal warning unit is signal connected to the alarm provided on the firing control box 1. The setting of the monitoring data reflection unit and the abnormal warning unit can promote the interaction of the balanced temperature sensing system, can display and remind the predicted data to the technician in time, and facilitate the technician to adjust the process parameters according to the predicted data, to ensure the quality stability of the roller kiln for firing the ceramic tile.

[0055] The data port of the firing control box 1 can also be connected to devices for data reflection display, including but not limited to displays, memories, and PC terminals, etc. The balanced temperature sensing processing unit can monitor the predicted temperature state in the furnace body 3 and the subsequent temperature feedback regulation, which are displayed to the technician through the monitoring data feedback unit cooperating with the data port, so that the technician can obtain the change state of the temperature in the furnace body 3 during the firing of the ceramic tile in the roller kiln, and then effectively adjust the parameters of the ceramic tile firing, promote the quality and efficiency of the ceramic tile firing, and also start the alarm through the abnormal alarm unit when the temperature is abnormal and the regulation is invalid. The alarm reminds the technician to effectively judge the abnormal position according to the reflected data, assist the technician to analyze the abnormal cause, promote the efficiency of the technician to handle the abnormality, reduce the influence degree on the quality of the ceramic tile firing, and then ensure the economic benefit of the roller kiln firing ceramic tile.

[0056] Figure 1 - Figure 13 It is shown that when the roller kiln is firing ceramic tiles, as the temperature control system 2 continuously controls the temperature in the furnace body 3, the temperature in the furnace body 3 continuously rises, and when the exhaust system 4 collects the flue gas in 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, which acts on the temperature sensing deformation sleeve 56 through the exhaust pipe 41 wall, so that the temperature sensing deformation filler in the temperature sensing deformation sleeve 56 produces corresponding elongation deformation under the action of the flue gas waste heat, thereby driving the sliding plate 52 and the balance linkage structure 6 to move upward under the guidance of the sliding rod 53.

[0057] When the temperature sensing deformation sleeves 56 on the plurality of exhaust pipes 41 all rise to the same height, the two horizontal sensing structures 7 between the adjacent two exhaust pipes 41 are kept horizontal through the connection of the hinge seat 8 and the through-hole hinge joint 81, so that the horizontal sensing structures 7 on the left and right sides of the same exhaust pipe 41 are kept horizontal, and the counterweight sliding block 73 in the horizontal sensing sleeve 71 is kept in the middle position of the horizontal sensing sleeve 71 under the action of gravity balance and the balance spring 75, so that the counterweight guide rod 731 does not trigger the sensing guide rod 741, and the constant disconnection state is maintained. At this time, the balanced temperature sensing processing unit can receive the signal data without triggering transmitted by the temperature difference state collecting unit, so that according to the state of the flue gas waste heat in the exhaust pipe 41, the uniformity of the temperature in the furnace body 3 is effectively judged, and no regulation compensation is needed, only the data transmission and display of the monitoring data reflection unit.

[0058] When the elongation deformation range generated by the temperature-sensitive deformation sleeve 56 outside the exhaust pipe 41 is small, the height of the upper slide plate 52 is lower than that of the slide plates 52 on the left and right sides, and the two horizontal sensing structures 7 between the two adjacent exhaust pipes 41 form a concave inclined state through the connection of the hinge seat 8 and the through-hole hinge joint 81, so that the horizontal sensing structures 7 on the left and right sides of the exhaust pipe 41 are inclined towards the direction close to the exhaust pipe 41, and the counterweight sliding block 73 in the horizontal sensing sleeve 71 moves towards the direction close to the exhaust pipe 41 under the action of gravity, and the balance spring 75 at the corresponding position is deformed to contract, that is, the counterweight sliding block 73 on the left side moves to the right side and triggers the sensing guide rod 741 on the right side through the counterweight guide rod 731, and the counterweight sliding block 73 on the right side moves to the left side and triggers the sensing guide rod 741 on the left side through the counterweight guide rod 731, and the horizontal sensing structures 7 on the left and right sides of the same exhaust pipe 41 form double close trigger signals, and the temperature difference state acquisition unit transmits the double close trigger signals to the balanced temperature sensing processing unit, the balanced temperature sensing processing unit judges that the temperature uniformity in the furnace body 3 segment of the exhaust pipe 41 has the risk of abnormality, and the temperature is low, and then transmits the temperature control compensation data of the position to the temperature control system 2 through the temperature control feedback unit, and the temperature control system 2 accurately controls the temperature of the furnace body 3 according to the feedback data, such as shortening the gap of the intermittent operation of the ignition nozzle system 31 of the single position or increasing the control of the efficiency, or enhancing the wind force towards the position, to promote the uniformity of the temperature in the furnace body 3, so as to eliminate the temperature uniformity abnormality of the position in the furnace body 3 at this time and ensure the quality of ceramic firing.

[0059] When the elongation deformation range generated by the temperature-sensitive deformation sleeve 56 outside the plurality of smoke exhaust pipes 41 gradually decreases in a certain direction, and the direction is set to gradually decrease from left to right, the height of the slide plate 52 on the right side will gradually be lower than the height of the slide plate 52 on the left side, so that the plurality of horizontal sensing structures 7 connected through the hinge seat 8 and the through-hole hinge joint 81 will form an inclined state towards the right side, that is, the horizontal sensing structures 7 on the left and right sides of the same smoke exhaust pipe 41 produce parallel inclination, and then the counterweight sliding block 73 in the horizontal sensing sleeve 71 will move towards the right side under the action of gravity, causing the corresponding position of the balance spring 75 to produce shrinkage deformation, that is, the counterweight sliding block 73 on the left side moves to the right side, and the sensing guide rod 741 on the right side is triggered by the counterweight guide rod 731, the counterweight sliding block 73 on the right side moves to the right side, and the sensing guide rod 741 on the right side is triggered by the counterweight guide rod 731, and then the horizontal sensing structures 7 on the left and right sides of the same smoke exhaust pipe 41 form double same direction trigger signals, and the temperature difference state acquisition unit transmits the double same direction trigger signals to the balanced temperature sensing processing unit. The balanced temperature sensing processing unit judges that the temperature in the position of the furnace body 3 has the risk of abnormal temperature control, and then transmits the temperature control compensation data of the position to the temperature control system 2 through the temperature feedback unit, and the temperature control system 2 accurately controls the temperature in the furnace body 3 according to the feedback data, such as overall heating the furnace body 3 in the position to ensure the effectiveness of the firing temperature in the furnace body 3, avoid quality abnormal problems caused by too low firing temperature, and promote the yield rate of the roller kiln to fire the ceramic tiles, and promote the economy.

[0060] When the elongation deformation range generated by the temperature-sensitive deformation sleeve 56 outside the exhaust pipe 41 is large, the height of the upper slide plate 52 is higher than the height of the slide plates 52 on the left and right sides, and the two horizontal sensing structures 7 between the two adjacent exhaust pipes 41 form an inwardly convex inclined state through the connection of the hinge seat 8 and the through-hole hinge joint 81, causing the horizontal sensing structures 7 on the left and right sides of the exhaust pipe 41 to tilt away from the exhaust pipe 41, and the counterweight sliding block 73 in the horizontal sensing sleeve 71 moves away from the exhaust pipe 41 under the action of gravity, causing the corresponding balance spring 75 to contract and deform, i.e. the counterweight sliding block 73 on the left side moves to the left, and the sensing guide rod 741 on the left side is triggered by the counterweight guide rod 731, and the counterweight sliding block 73 on the right side moves to the right, and the sensing guide rod 741 on the right side is triggered by the counterweight guide rod 731, and the horizontal sensing structures 7 on the left and right sides of the same exhaust pipe 41 form double-remote triggering signals. The temperature difference state acquisition unit transmits the double-remote triggering signals to the balanced temperature processing unit, the balanced temperature processing unit judges that the temperature uniformity in the furnace body 3 of the exhaust pipe 41 section has the risk of being abnormal, and the temperature is high, and then transmits the temperature control compensation data of the position to the temperature control system 2 through the temperature control feedback unit, and the temperature control system 2 accurately controls the temperature of the furnace body 3 according to the feedback data, such as stopping the ignition of the ignition nozzle system 31 or reducing the efficiency of the control, which can not only ensure the temperature uniformity of each section of the furnace body 3, but also effectively reduce the energy loss and cost in the roller kiln operation process.

[0061] After the balanced temperature processing unit adjusts the temperature control system 2 through the temperature control feedback unit, the balanced temperature processing unit can monitor the smoke heat state in the exhaust pipe 41 of the adjusted furnace body 3 through the temperature difference state acquisition unit, and can verify the adjustment effect. If the verification is effective, the adjustment effect is maintained, and if the verification effect is not good, the abnormal alarm unit starts the alarm to remind the technician to handle the temperature control abnormality.

[0064] Figure 2 - Figure 11 The lower end of the linkage ring 61 is fixedly connected with a plurality of trigger sleeves 62 slidably sleeved outside the corresponding slide rods 53, the upper end of the bottom plate 51 is fixedly connected with a plurality of temperature sensing touch sleeves 54 sleeved outside the slide rods 53, and the temperature sensing touch sleeve 54 cooperates with the trigger sleeve 62, the input end of the balanced temperature sensing processing unit is also connected with a waste heat lower limit collection unit, the input end of the waste heat lower limit collection unit is connected with the temperature sensing touch sleeve 54, the cooperation of the waste heat lower limit collection unit and the temperature sensing touch sleeve 54 can realize effective sensing and triggering display of the waste heat of each section of flue gas, which is convenient for the subsequent temperature control feedback unit to transmit temperature control compensation parameters to the temperature control system 2, timely improve the temperature in the furnace body 3, ensure the effect and quality of the ceramic tile firing, and through the cooperation of the waste heat upper limit collection unit, the risk of imbalance of the temperature uniformity in the subsequent furnace body 3 caused by the temperature of this section exceeding the limit can be effectively avoided, the refinement of temperature control is promoted, the temperature difference fluctuation range of each section in the furnace body 3 is reduced, and thus the economy of the roller kiln application is effectively promoted.

[0065] Figure 1 and Figure 2 The input end of the balanced temperature sensing processing unit is also connected with a positioning corresponding unit, the input end of the positioning corresponding unit is signal connected with a data port provided on the firing control box 1, the output end of the balanced temperature sensing processing unit is also connected with an independent ignition auxiliary unit, the output end of the independent ignition auxiliary unit is signal connected with an ignition nozzle system 31 installed on the furnace body 3 through the temperature control system 2, through the cooperation of the positioning corresponding unit and the independent ignition auxiliary unit, the balanced temperature sensing unit can assist in verifying abnormal causes when the temperature data in the furnace body 3 fluctuates, which can reduce the difficulty of state monitoring and maintenance of the ignition nozzle system 31, and also effectively promote the accuracy and effectiveness of the subsequent temperature control feedback unit to generate compensation data for the temperature control system 2.

[0066] It should be noted that the technical personnel input the setting number and corresponding position data of the ignition nozzle system 31 and the exhaust pipe 41 arranged on the actual roller kiln through the data port to the positioning corresponding unit, and the positioning corresponding unit processes and converts the received data and transmits it to the balanced temperature sensing processing unit, so that the balanced temperature sensing processing unit can control the ignition nozzle system 31 near the position of the exhaust pipe 41 with temperature abnormity in the subsequent position, and verify the abnormal cause.

[0067] Figure 1 - Figure 13 It is shown that the balanced temperature sensing processing unit predicts the temperature state in the furnace body 3 through the feedback of the flue gas heat state of the temperature difference state acquisition unit, and the slide plate 52 generates corresponding up and down movement under the thermal deformation action of the temperature sensing deformation sleeve 56, and simultaneously drives the linkage ring 61 to generate synchronous movement action.

[0068] When the slide plate 52 continuously moves up until the slide plate 52 abuts against the trigger baffle 55 to trigger, the residual heat upper limit acquisition unit can obtain trigger data and transmit the upper limit trigger data to the balanced temperature sensing processing unit. The balanced temperature sensing processing unit judges the state of the overall temperature in the furnace body 3 according to the number of triggered trigger baffles 55. When the number of triggered trigger baffles 55 is greater than one-third, it indicates that the overall temperature in the furnace body 3 at this time is in the upper limit data of temperature control, which is in a higher state. Therefore, the temperature control feedback unit sends a signal of regulation and compensation to the temperature control system 2, so that the temperature control system 2 can control the overall temperature in the furnace body 3, which can effectively reduce the energy loss in the firing process while ensuring the firing quality of the ceramic tiles. When the number of triggered trigger baffles 55 is less than or equal to one-third, according to the data transmitted by the temperature difference state acquisition unit, the temperature control feedback unit sends a signal of regulation and compensation to the temperature control system 2, so as to regulate and maintain the uniformity of the temperature in the furnace body 3, so as to avoid the adverse problems of ceramic tile firing caused by the temperature difference of each section.

[0069] When the sliding plate 52 drives the linkage ring 61 to continuously move downward until the trigger sleeve 62 abuts against the temperature-sensitive trigger sleeve 54 to trigger, the residual heat lower limit acquisition unit can obtain trigger data and transmit the lower limit trigger data to the balanced temperature processing unit. The balanced temperature processing unit determines the state of the overall temperature in the furnace body 3 according to the number of temperature-sensitive trigger sleeves 54 triggered. When the number of temperature-sensitive trigger sleeves 54 triggered is greater than one-third, it indicates that the overall temperature in the furnace body 3 at this time is at the lower limit data of temperature control, which is in a lower state. Therefore, the temperature control feedback unit sends a signal for compensation adjustment to the temperature control system 2, so that the temperature control system 2 can control the overall temperature in the furnace body 3 to ensure the quality and efficiency of the ceramic tile firing. When the number of temperature-sensitive trigger sleeves 54 triggered is less than or equal to one-third, the temperature control feedback unit sends a signal for compensation adjustment to the temperature control system 2 according to the data transmitted by the temperature difference state acquisition unit, so as to control and maintain the uniformity of the temperature in the furnace body 3, thereby avoiding the adverse problems of ceramic tile firing caused by temperature differences in different sections.

[0070] When the balanced temperature processing unit determines that the furnace body 3 has an abnormal risk of temperature uniformity according to the double-close trigger signals transmitted by the temperature difference state acquisition unit or the lower limit trigger data transmitted by the residual heat lower limit acquisition unit, the balanced temperature processing unit determines the corresponding ignition nozzle system 31 in the abnormal section according to the position data of the exhaust pipe 41 and the ignition nozzle system 31 transmitted by the positioning corresponding unit, and then uses the independent ignition auxiliary unit to control the ignition nozzle system 31 to generate a corresponding control instruction for increasing the efficiency. Then, the effect of the control of the ignition nozzle system 31 is determined according to the data fed back by the subsequent temperature difference state acquisition unit or the residual heat lower limit acquisition unit. When the control of the ignition nozzle system 31 is effective, the monitoring data reflecting unit displays the abnormal problem of the efficiency of the ignition nozzle system 31 in this section to the technician, which may exist problems such as burner carbon deposition and needs to be maintained. The technician can determine the cause of the temperature control abnormality, and at the same time, the temperature control feedback unit transmits 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 time.

[0071] When the control of the ignition nozzle system 31 is not effective, the temperature control feedback unit transmits the control compensation data to the temperature control system 2, so that the temperature control system 2 performs corresponding temperature control on the section of the furnace body 3, and transmits the verified data to the technician through the monitoring data reflecting unit, so that the technician can determine the cause of the temperature uniformity abnormality in this section, thereby promoting the subsequent technicians to adjust the process parameters and promoting the continuous application of the roller kiln to the firing quality and control precision.

[0072] The above-mentioned embodiments of the present application are combined with the current actual demand, the protection scope is not limited to this, various changes made within the knowledge range of the person skilled in the art without departing from the concept of the present application still fall within the protection scope of the present application.
