[0002] Boilers are core equipment in the field of energy conversion, widely used in power generation, chemical production, industrial heating and household heating, and the core function is to release heat energy through fuel combustion to heat water into steam or hot water to provide power and heat support for production and life. Its technical development has always been around the core needs of high efficiency, low emission and adaptability to working conditions, and has gradually developed towards high-parameter operation and clean fuel adaptation with the improvement of industry's requirements for energy utilization efficiency and environmental protection. The solid boiler pipe is a solid metal blank pipe for manufacturing core pressure-bearing or heat-exchanging components of the boiler, and is the basis for subsequent high-temperature forming processing into a hollow finished pipe. As the "blank" of key components such as boiler superheater pipe, reheater pipe and economizer pipe, it is processed into a hollow pipe through processes such as hot rolling and cold rolling, and is commonly used in materials such as carbon steel, low alloy steel and heat-resistant alloy.

SUMMARY
[0004] The purpose of the present application is to provide a high-temperature forming device for solid boiler pipes to solve the problems in the prior art.

[0008] As a preferred technical solution, a slide is formed in the inner circle of the annular shell, a folding dustproof belt is mounted in the slide, and the plurality of nozzles penetrate the folding dustproof belt. When the nozzles rotate with the moving blocks, the folding dustproof belt stretches or shrinks with the nozzles, preventing dust and oxide from entering the annular shell and causing damage to the equipment.
[0009] As a preferred technical solution, the blockage prevention assembly comprises a boss, a rotating ring, a slide rod, a rotating disc, an arc-shaped block and a first spring. The chamber is arranged in the moving block, a boss for replacing the nozzle is arranged in the chamber, a rotating ring is rotatably arranged on the top of the boss, a slide rod is slidably arranged in the rotating ring, a rotating disc is arranged on the bottom of the slide rod, a plurality of arc-shaped blocks for cleaning the inner wall of the nozzle are rotatably arranged on the rotating disc, the arc-shaped blocks are connected with the slide rod through the first spring, when the nozzle stops working, dust and oxide skin will enter the nozzle and cause blockage, the rotating ring drives the slide rod to rotate, so that the rotating disc rotates synchronously with the slide rod, at this time, the arc-shaped blocks are opened and touch the inner wall of the nozzle under the centrifugal force generated by the rotation of the rotating disc, and the rotating disc is lowered in the process of rotation through the slide rod pressed by the lifting rod, so that the nozzle is cleaned.
[0010] As a preferred technical scheme, a plurality of square grooves are arranged on the arc-shaped blocks, a spring sheet for rebounding impact force is rotatably arranged in the square groove, the spring sheet is connected with the bottom of the square groove through a reset rod, a second spring is sleeved on the reset rod, when the arc-shaped block touches the inner wall of the nozzle, the reset rod and the second spring are compressed by extruding the spring sheet, the arc-shaped block is driven to shrink to the center of the rotating disc under the certain rebound force of the reset rod and the second spring, so that the arc-shaped block stops touching the inner wall of the nozzle, and then the arc-shaped block touches the inner wall of the nozzle again under the centrifugal force, so that the inner wall of the nozzle is intermittently knocked, and the effect of preventing dust and oxide skin from blocking the nozzle is achieved.
[0011] As a preferred technical scheme, a lifting rod is arranged on the top of the chamber, a rotating sleeve for driving the slide rod to slide up and down is arranged on the output end of the lifting rod, the rotating sleeve is rotatably arranged on the top of the slide rod, a large pulley is arranged on the rotating ring, a drive motor is arranged on the bottom of the chamber, a small pulley is arranged on the output shaft of the drive motor, and a drive belt is sleeved on the small pulley and the large pulley, when the flow detector detects that the water output of the nozzle decreases significantly within a continuous time, the drive motor is started, the small pulley on the drive motor rotates, the large pulley and the small pulley rotate synchronously under the action of the drive belt, so that the rotating ring is provided with rotating force under the joint action of the large pulley and the small pulley, and the rotating disc at the bottom of the slide rod is driven to rotate, and the lifting rod is intermittently lowered, so that the arc-shaped blocks have enough time to clean the inner wall of the nozzle.
[0012] As a preferred technical scheme, a plurality of flow detectors are arranged on the nozzles, and the flow detectors are electrically connected with the drive motor and the lifting rod.
[0013] As a preferred technical solution, the water supply device 5 is connected to multiple nozzles 25 through pipes. A speed detector 41 is installed on the guide rail 4. The speed detector 41 is electrically connected to the water supply device 5. The water supply volume of the water supply device is controlled by detecting the pulling speed of the straightening machine. The faster the pulling speed, the greater the water supply volume. This ensures that thermal stress cracks will not occur due to excessive water supply or insufficient cooling due to weak water supply, which would lead to insufficient solidification in the center of the billet and increase the risk of shrinkage cavities and porosity, while ensuring solidification efficiency.
[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The water supply unit begins supplying water to the nozzles. Multiple nozzles spray water evenly onto the surface of the casting billet to cool it down, thus cooling the billet from the surface to the center until it is completely solidified. When a nozzle is damaged and cannot discharge water, the normally functioning nozzles on the moving block are redistributed evenly on the circumference by rotating the drive ring. This prevents uneven cooling from causing elliptical shapes and surface cracks, thus improving the yield. The drive box controls multiple drive rings to drive the moving block to distribute the nozzles evenly within the annular shell. When a nozzle is damaged and cannot discharge water, the drive ring needs to redistribute the nozzles on the moving block evenly on the circumference. The drive box is precisely controlled by a sensor that senses the scale groove, thus achieving uniform distribution of the nozzles. As the nozzles rotate with the moving block, the folded dustproof belt extends or retracts with the nozzles to prevent dust and oxide scale from entering the annular shell and causing equipment damage.
[0015] 2. In this application, after the nozzle stops discharging water, dust and scale will enter the nozzle and cause blockage. By controlling the rotating ring to drive the sliding rod to rotate, the turntable rotates synchronously with the sliding rod. At this time, the arc-shaped block opens and touches the inner wall of the nozzle under the centrifugal force generated by the rotation of the turntable. At the same time, the lifting rod presses down the sliding rod, causing the turntable to move down during the rotation, thereby cleaning the nozzle. When the arc-shaped block contacts the inner wall of the nozzle, it will compress the reset rod and the second spring by squeezing the spring plate. When the reset rod and the second spring have a certain rebound force, they will drive the arc-shaped block to retract towards the center of the turntable, thereby stopping contact with the inner wall of the nozzle. Then, under the action of centrifugal force, the arc-shaped block will contact the inner wall of the nozzle again, thereby achieving intermittent tapping of the inner wall of the nozzle, thus preventing dust and scale from clogging the nozzle.
[0016] 3. When the flow detector detects a significant decrease in the water output of the nozzle over a given period of time, this application starts the drive motor, causing the small pulley on the drive motor to rotate. Under the action of the drive belt, the large and small pulleys rotate synchronously, thereby providing rotational force to the rotating ring under the combined action of the large and small pulleys, which in turn drives the turntable at the bottom of the slide bar to rotate. At the same time, the lifting rod descends intermittently, giving the arc block enough time to clean the inner wall of the nozzle. The water supply of the water supply device is controlled by detecting the pulling speed of the straightening machine through the speed detector. The faster the pulling speed, the greater the water supply, ensuring that thermal stress cracks are not caused by excessive water supply or insufficient water cooling, which would lead to insufficient solidification at the center of the billet and increase the risk of shrinkage cavities and porosity, while ensuring solidification efficiency.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example: Figures 1-5 As shown, the present invention provides a technical solution for a high-temperature forming equipment for solid tubes used in boilers. The high-temperature forming equipment for solid tubes used in boilers includes a crystallizer 1, a guide rail 4 installed at the outlet end of the crystallizer 1, a water supply 5 installed on one side of the guide rail 4, a straightening machine 6 installed at the end of the guide rail 4, and multiple sets of uniform water spraying components 2 arranged on the guide rail 4. The multiple sets of uniform water spraying components 2 are all connected to the water supply 5 through pipes. A smelting machine 7 is installed above the crystallizer 1, and the smelting machine 7 is connected to the inlet of the crystallizer 1 through a pipe. The uniform water spray assembly 2 includes an annular shell 21, a slide 211, a mounting bracket 22, a drive ring 23, a moving block 24, an arc-shaped channel 241, and a nozzle 25; An annular shell 21 is installed at the outlet end of the crystallizer 1. Two mounting brackets 22 are symmetrically installed inside the annular shell 21. Multiple drive rings 23 are rotatably mounted on the two mounting brackets 22. A movable block 24 is installed at the bottom of each drive ring 23. An arc-shaped channel 241 is opened at the top of each movable block 24 to facilitate contact with the inner ring of the drive ring 23. A nozzle 25 is installed at the bottom of each movable block 24. An anti-clogging component 3 is installed inside each movable block 24. When the billet exits the crystallizer 1 and is initially cooled, a billet shell is quickly formed, but the inner... The billet remains as a cast ingot, then passes through the annular shell 21 under the action of the guide rail 4. At the same time, the water supply device 5 starts to supply water to the nozzles 25. Multiple nozzles 25 spray water evenly on the surface of the billet to cool it down, so that the billet cools from the surface to the center until it is completely solidified. When a nozzle 25 is damaged and cannot discharge water, the normally working nozzles 25 on the moving block 24 can be redistributed evenly on the 360° circumference by rotating the drive ring 23, so as to avoid uneven cooling that may cause elliptical shapes and surface cracks, and improve the yield.
[0021] The top of the annular shell 21 is equipped with a drive box 26 for driving multiple drive rings 23, and the multiple drive rings 23 rotate independently. By controlling the multiple drive rings 23 through the drive box 26, the moving blocks 24 can be evenly distributed inside the annular shell 21.
[0022] The surfaces of multiple drive rings 23 are provided with scale grooves 231. A sensor 27 for sensing the scale grooves 231 is installed on the annular shell 21. The sensor 27 is electrically connected to the drive box 26. When a nozzle 25 is damaged and cannot dispense water, the drive ring 23 needs to drive the nozzles 25 on the moving block 24 to redistribute them evenly on the circumference. The sensor 27 senses the scale grooves 231 to precisely control the drive box 26, thereby achieving a uniform distribution of the nozzles 25.
[0023] The inner ring of the annular shell 21 has a slide 211, and a folded dustproof belt 28 is installed inside the slide 211. Multiple nozzles 25 pass through the folded dustproof belt 28. When the nozzles 25 rotate with the moving block 24, the folded dustproof belt 28 extends or retracts with the nozzles 25 to prevent dust and oxide scale from entering the annular shell 21 and causing equipment damage.
[0024] like Figures 4-7 As shown, the anti-blocking component 3 includes a boss 31, a rotating ring 3101, a sliding rod 32, a turntable 36, an arc-shaped block 37, and a first spring 38; The movable block 24 has a chamber 242, and a boss 31 for replacing and installing the nozzle 25 is installed in the chamber 242. A rotating ring 3101 is rotatably installed on the top of the boss 31, and a sliding rod 32 is slidably installed in the rotating ring 3101. A turntable 36 is installed at the bottom of the sliding rod 32. Multiple arc-shaped blocks 37 for cleaning scale on the inner wall of the nozzle 25 are rotatably installed on the turntable 36. The multiple arc-shaped blocks 37 are connected to the end of the sliding rod 32 by a first spring 38. When the nozzle 25 stops spraying water, dust and oxide scale will enter the nozzle 25 and cause blockage. By controlling the rotating ring 3101 to drive the sliding rod 32 to rotate, the turntable 36 will rotate synchronously with the sliding rod 32. At this time, the arc-shaped blocks 37 open and touch the inner wall of the nozzle 25 under the action of centrifugal force generated by the rotation of the turntable 36. At the same time, the lifting rod 34 presses down the sliding rod 32 to move the turntable 36 down during the rotation, thereby achieving the cleaning effect on the nozzle 25.
[0025] Multiple arc-shaped blocks 37 are provided with square grooves 371. Spring plates 39 for rebounding impact force are rotatably installed in the square grooves 371. The spring plates 39 are connected to the bottom of the square grooves 371 through a reset rod 310. A second spring 311 is sleeved on the reset rod 310. When the arc-shaped block 37 contacts the inner wall of the nozzle 25, it will compress the reset rod 310 and the second spring 311 by squeezing the spring plates 39. When the reset rod 310 and the second spring 311 have a certain rebound force, they will drive the arc-shaped block 37 to retract towards the center of the turntable 36, thereby stopping the contact with the inner wall of the nozzle 25. Then, under the action of centrifugal force, the arc-shaped block 37 contacts the inner wall of the nozzle 25 again, thereby achieving intermittent knocking on the inner wall of the nozzle 25, which can prevent dust and oxide scale from clogging the nozzle 25.
[0026] A lifting rod 34 is installed on the top of the chamber 242. A rotating sleeve 33 for driving the slide rod 32 to slide up and down is installed on the output end of the lifting rod 34. The rotating sleeve 33 is rotatably installed on the top of the slide rod 32. A large pulley 3102 is installed on the rotating ring 3101. A drive motor 35 is installed at the bottom of the chamber 242. A small pulley 351 is installed on the output shaft of the drive motor 35. A drive belt is fitted on the small pulley 351 and the large pulley 3102. When the flow detector 312 detects a significant decrease in the water output of the nozzle 25 over a period of time, the drive motor 35 is started, causing the small pulley 351 on the drive motor 35 to rotate. Under the action of the drive belt, the large pulley 3102 and the small pulley 351 rotate synchronously, thereby providing rotational force to the rotating ring 3101 under the combined action of the large pulley 3102 and the small pulley 351, which in turn drives the turntable 36 at the bottom of the slide rod 32 to rotate. At the same time, the lifting rod 34 descends intermittently, giving the arc block 37 enough time to clean the inner wall of the nozzle 25.
[0027] Each nozzle 25 is equipped with a flow detector 312, which is electrically connected to the drive motor 35 and the lifting rod 34.
[0028] The water supply device 5 is connected to multiple nozzles 25 via pipes. A speed detector 41 is installed on the guide rail 4. The speed detector 41 is electrically connected to the water supply device 5. The speed detector 41 detects the pulling speed of the straightening machine 6 to control the water supply of the water supply device 5. The faster the pulling speed, the greater the water supply. This ensures that thermal stress cracks are not caused by excessive water supply or insufficient cooling by water supply, which would lead to insufficient solidification at the center of the billet and increase the risk of shrinkage cavities and porosity, while ensuring solidification efficiency.
[0029] Working principle of the invention: After the billet exits the crystallizer 1 and is initially cooled, it quickly forms a shell, but the inside is still the billet. Then, under the action of the guide rail 4, it passes through the annular shell 21. At the same time, the water supply device 5 starts to supply water to the nozzles 25. Multiple nozzles 25 spray water evenly on the surface of the billet to cool it down, so that the billet is cooled from the surface to the center until it is completely solidified. When a nozzle 25 is damaged and cannot discharge water, the normally working nozzles 25 on the moving block 24 can be redistributed evenly on the 360° circumference by rotating the drive ring 23, so as to avoid uneven cooling that causes elliptical shapes and surface cracks and improve the yield.
[0030] The drive box 26 controls multiple drive rings 23 to drive the moving blocks 24 to be evenly distributed within the annular shell 21.
[0031] When a nozzle 25 is damaged and cannot dispense water, the drive ring 23 needs to drive the nozzles 25 on the moving block 24 to redistribute them evenly around the circumference. The drive box 26 is precisely controlled by the sensor 27 sensing the scale groove 231, thereby achieving a uniform distribution of the nozzles 25. When the nozzles 25 rotate with the moving block 24, the folded dustproof belt 28 extends or retracts with the nozzles 25 to prevent dust and oxide scale from entering the annular shell 21 and causing equipment damage.
[0032] When the nozzle 25 stops dispensing water, dust and scale will enter and cause blockage. By controlling the rotating ring 3101 to rotate the sliding rod 32, the turntable 36 rotates synchronously with the sliding rod 32. At this time, the arc-shaped block 37 opens and touches the inner wall of the nozzle 25 under the centrifugal force generated by the rotation of the turntable 36. Simultaneously, the lifting rod 34 presses down the sliding rod 32, causing the turntable 36 to move downwards during rotation, thereby cleaning the nozzle 25. When the arc-shaped block 37... When the nozzle 25 touches the inner wall, the spring plate 39 is squeezed, which compresses the reset rod 310 and the second spring 311. When the reset rod 310 and the second spring 311 have a certain rebound force, they will drive the arc block 37 to retract towards the center of the turntable 36, thereby stopping the contact with the inner wall of the nozzle 25. Then, under the action of centrifugal force, the arc block 37 contacts the inner wall of the nozzle 25 again, thereby achieving intermittent knocking on the inner wall of the nozzle 25, which can prevent dust and oxide scale from clogging the nozzle 25.
[0033] When the flow detector 312 detects a significant decrease in the water output of the nozzle 25 over a period of time, it starts the drive motor 35, causing the small pulley 351 on the drive motor 35 to rotate. Under the action of the drive belt, the large pulley 3102 and the small pulley 351 rotate synchronously, thereby providing rotational force to the rotating ring 3101 under the combined action of the large pulley 3102 and the small pulley 351, which in turn drives the turntable 36 at the bottom of the slide bar 32 to rotate. At the same time, the lifting rod 34 descends intermittently, giving the arc block 37 enough time to clean the inner wall of the nozzle 25.
[0034] The water supply of the water supply device 5 is controlled by detecting the pulling speed of the straightening machine 6 through the speed detector 41. The faster the pulling speed, the greater the water supply, ensuring that thermal stress cracks are not caused by excessive water supply or insufficient cooling by water supply, which would lead to insufficient solidification in the center of the billet and increase the risk of shrinkage cavities and porosity, while ensuring solidification efficiency.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
