[0003] The multi-point heating burner is provided with multiple flame nozzles, which heat the furnace by delivering fuel gas and igniting a flame. Over a long period of use, the carbon deposited by combustion will adhere to the inner wall of the nozzle, which needs to be cleaned to prevent the fuel gas from burning inefficiently. When the nozzle is replaced for cleaning, the flange and bolt connection of the nozzle on the pipeline may not correspond to the bolt position of the flange due to different nozzle specifications, so the nozzle cannot be installed by bolts. In some existing technologies, to improve the adaptability of bolt installation, a long slot is formed on the flange, and the bolt is fixed on the flange by a nut after being inserted into the slot. However, the equipment may vibrate during operation, which may cause the nut and bolt to loosen and cause the bolt to shift or fall off, affecting the normal use of the nozzle and reducing stability. Therefore, a multi-point heating burner and control system are proposed to solve the above problems. SUMMARY

[0013] Preferably, the protrusion contacts the inner wall of the rotating rod, and the rotating rod passes through the outer wall of the fixing plate.
[0014] The present application also proposes a control system for a multi-point heating burner, comprising the following steps: S1. Before starting, a high-precision sensor is used to record the second-level pressure curve of the gas pipeline and simultaneously detect the negative pressure value of the air premixing chamber at each combustion point. If the negative pressure of any cavity deviates from the reference value, the compensation fan of the corresponding cavity is automatically turned on to replenish air until all detection points meet the starting conditions; S2. Activate the igniter. After the flame sensor confirms that the combustion is stable, it monitors the flame propagation time difference between adjacent combustion points in real time.

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.
[0021] Example 1 like Figures 1-6 As shown, the present invention provides a multi-point heating burner, including a gas delivery module 100, and also including: a gas delivery pipe 101, the outer wall of the gas delivery pipe 101 is fixedly connected to a fixing plate 102, the outer wall of the gas delivery pipe 101 is fixedly connected to a telescopic hose 103, the outer wall of the telescopic hose 103 is provided with a nozzle 104 via a connecting mechanism 200, the outer wall of the nozzle 104 is fixedly connected to an igniter 105, and the outer wall of the gas delivery module 100 is provided with an adjustment mechanism 300; The connecting mechanism 200 includes a connecting tube 201, a connecting plate 202 is fixedly connected to the outer wall of the connecting tube 201, a movable ring 204 is slidably connected to the outer wall of the connecting tube 201, and a limit assembly is provided on the outer wall of the movable ring 204; The limiting assembly includes a fixed block 210 , the inner wall of which is elastically connected to an inserting rod 212 via a connecting spring 211 .
[0022] The above solution is adopted: the gas delivery module 100 is a prior art, which can be connected to an external device to deliver gas to the gas pipe 101. The gas pipe 101 is connected to the pipeline in the gas delivery module 100. After passing through the gas pipe 101, the gas is sprayed out from the nozzle 104. After the igniter 105 of the nozzle 104 is started, the gas can be ignited to heat the furnace chamber of the heating furnace. The nozzle 104 extends into the furnace chamber; the telescopic hose 103 can be bent and stretched, and the angle of the nozzle 104 can be adjusted by the adjustment mechanism 300 to avoid Some areas in the furnace are overheated, so that the temperature in the furnace area is balanced; the nozzle 104 can be removed and installed on the telescopic hose 103 through the connecting mechanism 200. A flange is provided at the lower end of the nozzle 104, and the flange and the connecting plate 202 are fixed with bolts. When replacing different nozzles 104, the position of the slider 206 on the connecting plate 202 can be adjusted so that the slider 206 corresponds to the position of the threaded hole of the flange, so that nozzles 104 of different specifications can be flexibly installed, thereby improving adaptability and stability.
[0023] like Figure 2-Figure 4 As shown, the connecting mechanism 200 also includes a slider 206, which is hinged to the outer wall of the movable ring 204 through a hinge rod 205. The outer wall of the slider 206 is fixedly connected to a guide block 207, the outer wall of the connecting plate 202 is provided with a guide groove 203, and the outer wall of the connecting plate 202 is provided with a through groove 208.
[0024] The above scheme is adopted: in the connecting mechanism 200, the connecting pipe 201 is connected to the telescopic hose 103, and there are multiple groups of through grooves 208 on the connecting plate 202. Each group of through grooves 208 is correspondingly provided with a group of movable sliders 206. The sliders 206 are slidably connected to the guide grooves 203 through the guide blocks 207, and can be moved simultaneously along the outer wall of the connecting plate 202 toward the circumference or the center of the circle. During the movement, the threaded holes on the sliders 206 always correspond to the positions of the through grooves 208. When the positions of the threaded holes on the flange of the outer wall of the nozzle 104 are different, the position of the slider 206 can also be adjusted so that the threaded holes of the two always correspond to each other, and then connected by bolts and nuts, which ensures stability and is more flexible. Compared with the prior art in which bolts are inserted into long strip grooves for fixation, it is more stable and avoids the displacement or falling off of the bolts due to vibration during equipment operation.
[0025] like Figure 2-Figure 4 As shown, the connecting pipe 201 is fixedly connected to the outer wall of the telescopic hose 103, one end of the hinged rod 205 is hinged to the outer wall of the movable ring 204, and the other end of the hinged rod 205 is hinged to the outer wall of the slider 206; the slider 206 is slidably connected to the outer wall of the connecting plate 202, the guide block 207 is slidably connected to the inner wall of the guide groove 203, and the nozzle 104 and the connecting plate 202 are connected by bolts.
[0026] The above solution is adopted: the movable ring 204 can move on the outer wall of the connecting tube 201, and during the movement, the movable ring 204 will drive the end of the hinged rod 205 connected to it to move, and the other end of the hinged rod 205 will drive the slider 206 to move. Since the slider 206 can only move along the outer wall of the connecting plate 202, the hinged rod 205 will flip over. When the movable ring 204 moves toward the side of the connecting plate 202, the hinged rod 205 flips outward, and multiple groups of sliders 206 move toward the circumference of the connecting plate 202 at the same time, otherwise they will move toward the center of the connecting plate 202, so that the positions of multiple groups of sliders 206 can be adjusted at the same time.
[0027] like Figure 4 As shown, a circular groove 213 is provided on the outer wall of the connecting tube 201, the insertion rod 212 is engaged with the circular groove 213, and the fixed block 210 is fixedly connected to the outer wall of the movable ring 204; one end of the connecting spring 211 is fixedly connected to the outer wall of the insertion rod 212, and the other end of the connecting spring 211 is fixedly connected to the inner wall of the fixed block 210, and the insertion rod 212 is slidably connected to the inner wall of the fixed block 210.
[0028] By adopting the above scheme: the limiting component can limit the movable ring 204 conveniently and quickly, thereby fixing the position of the hinged rod 205 and the slider 206; under normal circumstances, the insertion rod 212 remains in a state of being engaged with a group of circular grooves 213 due to the elastic force of the connecting spring 211. When the operator pulls the insertion rod 212 upward, the connecting spring 211 is compressed, and the insertion rod 212 is disengaged from the circular groove 213, and the movable ring 204 can be moved; when it is moved to the appropriate position, the insertion rod 212 can be loosened, and under the action of the elastic force of the connecting spring 211, the insertion rod 212 is inserted into another group of circular grooves 213 to complete the fixation; there are multiple groups of circular grooves 213, and the movable ring 204 can be moved to multiple positions and fixed, thereby adapting to nozzles 104 of different specifications.
[0029] Example 2 like Figure 5-Figure 6 As shown, the adjustment mechanism 300 includes a cylinder 301, the movable end of the cylinder 301 is fixedly connected to a movable plate 302, the outer wall of the movable plate 302 is provided with a slide groove 305, the inner wall of the slide groove 305 is slidably connected to a movable block 304, the inner wall of the fixed plate 102 is rotatably connected to a rotating block 306, the outer wall of the rotating block 306 is fixedly connected to a rotating rod 303, the outer wall of the telescopic hose 103 is fixedly connected to a protrusion 307, and the outer wall of the telescopic hose 103 is fixedly connected to a cross bar 308.
[0030] The above scheme is adopted: the cylinder 301 is arranged on both sides of the gas delivery module 100, and a group of movable plates 302 are provided on both sides. When the cylinder 301 is started, the movable end will drive the movable plate 302 to move vertically up and down; the top of the rotating rod 303 is connected to the telescopic hose 103 through the protrusion 307, and the rotating rod 303 can be flipped with the rotating block 306 as the center. During the flipping process, it can drive the telescopic hose 103 to bend and extend, and then drive the nozzle 104 to flip to the middle or both sides to adjust the angle and position of the flame injection; when the temperature processor in the furnace detects that the temperature is uneven, it can control the cylinder 301 to start and automatically adjust the angle of the nozzle 104, so that the temperature of the area in the furnace can be balanced during operation.
[0031] like Figure 5-Figure 6 As shown, the cylinder 301 is fixedly connected to the top outer wall of the gas delivery module 100, the moving block 304 is rotatably connected to the rotating rod 303; the protrusion 307 contacts the inner wall of the rotating rod 303, and the rotating rod 303 passes through the outer wall of the fixed plate 102.
[0032] Using the above solution: Figure 6 As shown, when the cylinder 301 drives the movable plate 302 to move downward, the movable block 304 will pull the bottom end of the rotating rod 303 to move. Since the rotating rod 303 cannot move but can only rotate, the rotating rod 303 will rotate clockwise, and the movable block 304 will move horizontally to the left in the inner wall of the slide groove 305. The rotating rod 303 rotates around the rotating block 306 and drives it to rotate synchronously. The top of the rotating rod 303 generates pressure on the protrusion 307, causing the protrusion 307 to move along the inner wall of the empty groove at the top of the rotating rod 303. As the protrusion 307 moves, the top of the telescopic hose 103 is driven to bend clockwise downward, which can drive the spray head 104 to rotate synchronously clockwise to adjust the angle. Since multiple groups of telescopic hoses 103 are connected by cross bars 308, multiple groups of spray heads 104 on one side can be driven to rotate synchronously. Conversely, when the movable plate 302 moves upward, it drives the spray head 104 to rotate counterclockwise. Figure 5 As shown, by moving the movable plate 302, the nozzles 104 on both sides can be driven to rotate synchronously toward the middle or both sides, so that the flame is sprayed toward the middle or both sides of the furnace, thereby adjusting the temperature in the furnace to make it more balanced.
[0033] The present application also proposes a control system for a multi-point heating burner, comprising the following steps: S1. Before starting, a high-precision sensor is used to record the second-level pressure curve of the gas pipeline and simultaneously detect the negative pressure value of the air premixing chamber at each combustion point. If the negative pressure of any cavity deviates from the reference value, the compensation fan of the corresponding cavity is automatically turned on to replenish air until all detection points meet the starting conditions; S2. Activate the igniter 105. After the flame sensor confirms that the combustion is stable, it monitors the flame propagation time difference between adjacent combustion points in real time. If the difference exceeds 0.3 seconds, the ignited unit is immediately disconnected and a secondary ignition is performed. At the same time, the gas valve opening is adjusted. S3. When the temperature sensor in a certain area detects a temperature difference exceeding ±2°C, differential adjustments are made to the surrounding combustion points in that area. The power of the central combustion point is increased by 12%, while the power of the combustion points on both sides is reduced by 5% and 8% respectively. Observation is conducted after the adjustment. If the temperature difference does not improve, the adjustment range is expanded. S4. Periodically collect the flue gas composition of each combustion point and establish a real-time air-fuel ratio correction coefficient library. When the oxygen content at a combustion point is 2% higher than the theoretical value, the corresponding air valve opening is automatically reduced and the gas valve opening is increased. If the oxygen content continues to be low, start the backup air pipeline and supplement the secondary air through the mixer to ensure the stability of the excess air coefficient.
[0034] The working principle and use process of the present invention: After the gas delivery module 100 is connected to the external equipment, the gas is delivered to the gas pipe 101. The gas enters the telescopic hose 103 through the gas pipe 101, then reaches the nozzle 104 through the connecting pipe 201, and finally is ejected from the nozzle 104. The igniter 105 ignites the ejected gas, and the flame heats the furnace chamber of the heating furnace.
[0035] When the temperature processor in the furnace detects that the temperature is uneven, it will control the cylinder 301 in the regulating mechanism 300 to start. If the temperature on both sides of the furnace is higher than the temperature in the middle, the cylinder 301 drives the movable plate 302 to move downward, and the movable block 304 pulls the bottom end of the rotating rod 303 to move. At the same time, the movable block 304 moves horizontally to both sides in the sliding groove 305, driving the rotating rods 303 on both sides to flip toward the middle. The top of the rotating rod 303 generates pressure on the protrusion 307, causing the protrusion 307 to move along the inner wall of the empty groove at the top of the rotating rod 303, bringing The top of the movable telescopic hose 103 bends downward, thereby driving the nozzle 104 to rotate toward the middle to adjust the angle, so that the flame of the nozzle 104 is sprayed toward the middle of the furnace; conversely, if the temperature in the middle of the furnace is higher than that on both sides, the cylinder 301 can be used to move the movable plate 302 upward, and the nozzle 104 is rotated to both sides; by adjusting the angle of the nozzle 104 to make the flame spray toward the middle or both sides of the furnace, the temperature in the furnace can be balanced during operation, avoiding the problem of overheating of a certain area in the furnace due to uneven temperature, which causes coking of the furnace tubes in the furnace.
[0036] When the inside of the nozzle 104 needs to be cleaned, a nozzle 104 of a different specification needs to be replaced. If the threaded hole on the nozzle flange 104 does not correspond to the position of the slider 206, the operator can pull the plug rod 212 upwards, compress the connecting spring 211, release the limit of the movable ring 204 and move it, and drive multiple groups of sliders 206 to move simultaneously toward the circumference or center of the connecting plate 202 through the flipping of the hinged rod 205; after adjusting the slider 206 to the position corresponding to the threaded hole on the flange of the new nozzle 104, loosen the plug rod 212, insert the plug rod 212 into the corresponding circular groove 213, fix the position of the movable ring 204, the hinged rod 205 and the slider 206, and then use the bolt to pass through the threaded hole of the slider 206 and the threaded hole of the nozzle flange 104, and use the nut to fix the new nozzle 104 on the connecting plate 202 to complete the replacement.
[0037] It should be noted that, in the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
[0038] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
[0039] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.

10. A control system for a multi-point heating burner, applied to a multi-point heating burner according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Before starting, a high-precision sensor is used to record the second-level pressure curve of the gas pipeline and simultaneously detect the negative pressure value of the air premixing chamber at each combustion point. If the negative pressure of any cavity deviates from the reference value, the compensation fan of the corresponding cavity is automatically turned on to replenish air until all detection points meet the starting conditions; S2, activating the igniter (105), after the flame sensor confirms that the combustion is stable, monitor the flame propagation time difference between adjacent combustion points in real time. If the difference exceeds 0.3 seconds, immediately cut off the ignition unit and perform secondary ignition, and adjust the gas valve opening at the same time; S3. When the temperature sensor in a certain area detects a temperature difference exceeding ±2°C, differential adjustments are made to the surrounding combustion points in that area. The power of the central combustion point is increased by 12%, while the power of the combustion points on both sides is reduced by 5% and 8% respectively. Observation is conducted after the adjustment. If the temperature difference does not improve, the adjustment range is expanded. S4. Periodically collect the flue gas composition of each combustion point and establish a real-time air-fuel ratio correction coefficient library. When the oxygen content at a combustion point is 2% higher than the theoretical value, the corresponding air valve opening is automatically reduced and the gas valve opening is increased. If the oxygen content continues to be low, start the backup air pipeline and supplement the secondary air through the mixer to ensure the stability of the excess air coefficient.
