Description

A fixing structure for a waterless cold burner in an oxygen-fired furnace Technical Field

[0001] This utility model belongs to the technical field of industrial furnace thermal equipment, and in particular relates to a fixing structure for a waterless cold burner in an oxygen-heated furnace. Background Technology

[0002] With the increasing demands for energy efficiency and environmental protection in industrial production, oxy-fuel combustion technology has been widely applied in the field of heating furnaces. Compared with traditional air combustion, oxy-fuel combustion can significantly increase combustion temperature and reduce nitrogen oxide emissions from combustion products, thereby improving heating efficiency and reducing environmental pollution. However, under oxy-fuel combustion conditions, the burner faces higher temperatures and a more complex combustion environment, placing higher demands on the burner's structure and mounting method.

[0003] The existing fixing structure of the waterless cold burner in the all-oxygen heating furnace is to fix the burner in place to prevent it from shifting or shaking during use;

[0004] Existing equipment suffers from unstable mounting due to the large airflow impact force generated by the burner. This instability causes the burner to shift and wobble, resulting in the flame jet direction deviating from the set angle. Consequently, the product is not heated sufficiently, affecting product quality. Therefore, we propose a mounting structure for waterless cooling burners in an all-oxygen heating furnace. Summary of the Invention

[0005] The purpose of this utility model is to provide a fixing structure for a waterless cooling burner in an oxygen-fired furnace. Through the fixing mechanism and the adjusting mechanism, the problem of unstable equipment fixing caused by the large airflow impact force generated by the burner during use is solved. This unstable fixing will cause the burner to shift and shake, resulting in the flame jet direction deviating from the set angle, which in turn leads to insufficient product heating and affects product quality.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a fixing structure for a waterless cold burner in an oxygen-heated furnace, including a fixing plate, a sliding groove on the inner wall of the fixing plate, a fixing block fixedly connected to the bottom outer wall of the fixing plate, and a fixing mechanism provided on the outer wall of the fixing plate.

[0008] The fixing mechanism includes several L-plates, the outer walls of which are fixedly connected to the outer wall of the fixing plate. A rotating shaft is rotatably connected to the inner wall of each L-plate. A turntable is fixedly connected to the outer wall of the rotating shaft on the side away from the L-plate. Several circular grooves are formed on the inner wall of the turntable. Insert rods are slidably connected to the inner walls of the circular grooves. A positioning groove is formed on the inner wall of the L-plate on the right side. Several crown gears are fixedly connected to the outer wall of the rotating shaft. Several mounting brackets are fixedly connected to the top outer wall of the fixing plate. Rollers are rotatably connected to the inner walls of the mounting brackets. A gear is fixedly connected to the outer wall of the roller near the rotating shaft.

[0009] Furthermore, the outer wall of the gear meshes with the outer wall of the crown gear, a plurality of connecting rods are fixedly connected to the outer wall of the roller, a round rod is fixedly connected to the inner wall of the connecting rod, an installation block is slidably connected to the inner wall of the slide groove, a support plate is fixedly connected to the top outer wall of the installation block, a limit groove is formed on the inner wall of the support plate, the inner wall of the limit groove is slidably connected to the outer wall of the round rod, a clamping plate is fixedly connected to the outer wall of the end of the support plate away from the mounting frame, and an adjustment mechanism is provided on the inner wall of the fixed block.

[0010] Furthermore, the adjustment mechanism includes a rotating rod, the outer wall of which is fixedly connected to the inner wall of the fixed block, a worm gear fixedly connected to the outer wall of the rotating rod, a fixed base rotatably connected to the outer wall of the rotating rod, and a plurality of mounting plates fixedly connected to the outer wall of the fixed base.

[0011] Furthermore, a worm gear is rotatably connected to the inner wall of the mounting plate, and the outer wall of the worm gear meshes with the outer wall of the worm wheel.

[0012] Furthermore, a number of fixing rods are fixedly connected to the bottom outer wall of the fixed base, and a sleeve is slidably connected to the outer wall of the fixing rod. A mounting bracket is fixedly connected to the outer wall of the sleeve on the side away from the L-plate.

[0013] Furthermore, a number of square plates are fixedly connected to the bottom outer wall of the fixed base, the inner wall of the square plates is provided with inclined grooves, and a support frame is fixedly connected to the top outer wall of the base plate.

[0014] Furthermore, a first motor is fixedly connected to the inner wall of the support frame, and a threaded rod is fixedly connected to the bottom output shaft of the first motor through a coupling. A second sliding groove is provided on the inner wall of the base plate.

[0015] Furthermore, a slider two is slidably connected to the inner wall of the second groove, a support block is fixedly connected to the top outer wall of the slider two, the inner wall of the support block is threadedly connected to the outer wall of the threaded rod, a limit rod is fixedly connected to the inner wall of the support block, and the outer wall of the limit rod is slidably connected to the inner wall of the inclined groove.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model incorporates a crown gear clamping plate. When the roller rotates, it drives the connecting rod to rotate, which in turn drives the round rod to move. As the round rod moves, it slides in the limiting groove and simultaneously presses against the support plate, causing the support plate to move. At the same time, the support plate, along with the mounting block, slides in the slide groove. The movement of the support plate also moves the clamping plate, thereby improving the burner's stability and effectively fixing the burner. This prevents the burner from shifting due to the large airflow impact force generated during use, making the burner more stable during operation.

[0018] 2. This utility model incorporates a worm gear and a limiting rod. After the first motor starts, it rotates the threaded rod, which in turn moves the support block. As the support block moves, it causes the slider two to slide in the slide groove two. Simultaneously, the moving support block causes the limiting rod to slide in the inclined groove, and the limiting rod presses against the square plate, raising the square plate. This improves the flexibility of the equipment, allowing for flexible adjustment of the burner position according to different products, and preventing the burner flame from directly heating the product, which could lead to cracking.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please refer to Figures 1-7. This utility model is a fixing structure for a waterless cooling burner in an oxygen-fired furnace. It includes a fixing plate 1, with a groove 101 on the inner wall of the fixing plate 1. A fixing block 102 is fixedly connected to the bottom outer wall of the fixing plate 1. A fixing mechanism 2 is provided on the outer wall of the fixing plate 1. When the mounting block 213 slides in the groove 101, the mounting block 213 will not wobble, keeping the mounting block 213 in a straight line. The fixing mechanism 2 includes several L-plates 201. The outer walls of the L-plates 201 are all fixedly connected to the outer wall of the fixing plate 1. A rotating shaft 202 is rotatably connected to the inner wall of the L-plates 201. The outer wall of the rotating shaft 202 away from the L-plates 201 is fixedly connected to... A turntable 203 rotates, causing the shaft 202 to rotate as well, thus achieving kinetic energy transfer between the parts. The inner wall of the turntable 203 has several circular grooves 204, with insert rods 205 slidably connected to the inner walls of these grooves. A positioning groove 206 is located on the inner wall of the right-side L-plate 201. When the insert rod 205 is inserted from the circular groove 204 into the positioning groove 206, it fixes the turntable 203, preventing it from rotating. Several crown gears 207 are fixedly connected to the outer wall of the shaft 202. Several mounting brackets 208 are fixedly connected to the top outer wall of the fixing plate 1. Rollers 209 are rotatably connected to the inner walls of the mounting brackets 208. The rollers 209 are close to the shaft. A gear 210 is fixedly connected to the outer wall of one end of the shaft 202. When the shaft 202 rotates, it drives the crown gear 207 to rotate, and then the crown gear 207 drives the gear 210 to rotate. At the same time, the roller 209 rotates with the gear 210, completing the kinetic energy transfer between the parts. The outer wall of the gear 210 meshes with the outer wall of the crown gear 207. Several connecting rods 211 are fixedly connected to the outer wall of the roller 209. A round rod 212 is fixedly connected to the inner wall of the connecting rod 211. When the roller 209 rotates, it drives the connecting rod 211 to rotate, and then the connecting rod 211 drives the round rod 212 to move, realizing the kinetic energy transfer between the parts. A mounting block 213 is slidably connected to the inner wall of the slide groove 101. A support plate 214 is fixedly connected to the top outer wall of the mounting block 213. A limiting groove 215 is opened on the inner wall of the support plate 214. When the round rod 212 moves, it will slide in the limiting groove 215. At the same time, the round rod 212 will squeeze the support plate 214, causing the support plate 214 to move, thus completing the kinetic energy transfer between the parts. The inner wall of the limiting groove 215 is slidably connected to the outer wall of the round rod 212. A clamping plate 216 is fixedly connected to the outer wall of the end of the support plate 214 away from the mounting bracket 208. An adjustment mechanism 3 is provided on the inner wall of the fixing block 102. When the support plate 214 moves, it will move the clamping plate 216 with it. When the clamping plate 216 moves, it will clamp and fix the burner.

[0032] The adjusting mechanism 3 includes a rotating rod 301, the outer wall of which is fixedly connected to the inner wall of a fixed block 102. A worm gear 302 is fixedly connected to the outer wall of the rotating rod 301, and a fixed base 303 is rotatably connected to the outer wall of the rotating rod 301. Several mounting plates 304 are fixedly connected to the outer wall of the fixed base 303, and a worm gear 305 is rotatably connected to the inner wall of the mounting plate 304. When the worm gear 305 rotates, it drives the worm gear 302 to rotate, and then the worm gear 302 drives the rotating rod 301 to rotate. When rotating, it will rotate along with the fixed block 102, making it convenient for the operator to adjust the angle of the equipment. The outer wall of the worm 305 meshes with the outer wall of the worm wheel 302. Several fixed rods 306 are fixedly connected to the bottom outer wall of the fixed base 303. The outer wall of the fixed rod 306 is slidably connected to the sleeve 307. The outer wall of the sleeve 307 away from the L plate 201 is fixedly connected to the mounting bracket 208. When the fixed rod 306 slides in the sleeve 307, the fixed rod 306 will not wobble left and right, so that the fixed rod 306 maintains linear motion.

[0033] Several square plates 309 are fixedly connected to the bottom outer wall of the fixed base 303. The inner wall of each square plate 309 has a slanted groove 310. A support frame 311 is fixedly connected to the top outer wall of the base plate 308. A first motor 312 is fixedly connected to the inner wall of the support frame 311. When the operator starts the first motor 312, a threaded rod 313 is fixedly connected to the bottom output shaft of the first motor 312 via a coupling. A second sliding groove 314 is provided on the inner wall of the base plate 308. A second slider 315 is slidably connected to the inner wall of the second sliding groove 314. When the second slider 315 slides in the second sliding groove 314, it will maintain horizontal movement to prevent wobbling. A support block 316 is fixedly connected to the top outer wall of slider 315. The inner wall of the support block 316 is threadedly connected to the outer wall of the threaded rod 313. A limit rod 317 is fixedly connected to the inner wall of the support block 316. The outer wall of the limit rod 317 is slidably connected to the inner wall of the inclined groove 310. After the first motor 312 starts, it will rotate the threaded rod 313. Then the threaded rod 313 will move the support block 316. When the support block 316 moves, it will move the limit rod 317. Then the limit rod 317 will slide in the inclined groove 310. At the same time, the limit rod 317 will press the square plate 309, making the square plate 309 rise, so that the operator can adjust the height of the equipment.

[0034] One specific application of this embodiment is:

[0035] When the operator needs to use the equipment, first place the burner between the two clamping plates 216. While the burner is in the middle of the clamping plates 216, rotate the turntable 203. As the turntable 203 rotates, it drives the rotating shaft 202 to rotate. Then, the rotating shaft 202 drives the crown gear 207 to rotate. As the crown gear 207 rotates, it drives the gear 210 to rotate. Then, the gear 210 drives the roller 209 to rotate. As the roller 209 rotates, it drives the connecting rod 211 to rotate. Then, the connecting rod 211 drives the round rod 212 to move. As the round rod 212 moves, it... The burner slides in the limiting groove 215, while the round rod 212 presses against the support plate 214, causing the support plate 214 to move. Simultaneously, the support plate 214, along with the mounting block 213, slides in the slide groove 101. As the support plate 214 moves, it also moves the clamping plate 216, which then secures the burner to prevent it from wobbling during use. After securing, the insertion rod 205 is inserted from the round groove 204 into the positioning groove 206, preventing the turntable 203 from rotating and preventing the clamping plate 216 from loosening. Then, it can rotate during use. The worm gear 305 rotates, causing the worm wheel 302 to rotate. The worm wheel 302 then rotates the rotating rod 301, and simultaneously, the fixed block 102 rotates with the rotating rod 301. The rotation of the fixed block 102 causes the fixed plate 1 to rotate, facilitating adjustment of the burner's injection angle. Then, the first motor 312 can be started. After the first motor 312 starts, it rotates the threaded rod 313. The rotation of the threaded rod 313 causes the support block 316 to move. The movement of the support block 316 causes the slider 2 315 to move along the slide groove 2 314. As the support block 316 moves, it will slide the limiting rod 317 in the inclined groove 310. At the same time, the limiting rod 317 will press the square plate 309, causing the square plate 309 to rise. When the square plate 309 rises, it will move the fixed base 303. Then the fixed base 303 will slide the fixed rod 306 in the sleeve 307. When the fixed base 303 moves, it will move the rotating rod 301. Then the rotating rod 301 will move the fixed block 102. At the same time, the fixed plate 1 moves with the fixed block 102, which makes it convenient for the operator to adjust the burner height.
