Description

Technical Field

[0001] This invention relates to the field of tubular heat exchanger technology, specifically to an integrated brazed high-pressure resistant tubular heat exchanger. Background Technology

[0002] Tubular heat exchangers are a type of general-purpose heat exchange equipment that uses metal tubes as heat transfer elements and achieves heat exchange between two or more fluids through the thermal conduction of the tube walls. They are widely used in industrial fields such as chemical, petroleum, power, and refrigeration.

[0003] During long-term heat exchange, existing integrated tubular heat exchangers accumulate a significant amount of fouling inside. Since the core of a tubular heat exchanger is heat transfer between fluids through the tube walls, the continuous accumulation of fouling reduces the heat transfer efficiency, necessitating regular cleaning. However, cleaning existing heat exchangers often requires manual operation with hand tools, and since integrated tubular heat exchangers cannot be disassembled, manual tools can only be inserted through limited openings such as the inlet and outlet, making it difficult to reach deep into the tube walls, pipe gaps, and corners. These areas become stubborn cleaning blind spots, resulting in incomplete cleaning of the integrated tubular heat exchanger.

[0004] Therefore, we propose an integrated brazed high-pressure resistant tubular heat exchanger to solve the problems mentioned above. Summary of the Invention

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.

[0022] Please see Figure 1-10 The present invention provides a technical solution: an integrated brazed high-pressure resistant tubular heat exchanger. The device includes a heat exchanger body 1. A first cleaning assembly 2 is disposed inside the heat exchanger body 1. The first cleaning assembly 2 includes a ring 201. Multiple evenly arranged vertical teeth 202 are fixedly connected to the outer surface of one side of the ring 201. Multiple sliding plates 203 are slidably connected to the inner wall of the other side of the ring 201. A toothed ring 204 is fixedly embedded in the inner wall of the ring 201. Multiple evenly arranged internal helical gears 205 are rotatably connected to the outer surface of the ring 201. A first brush 206 is fixedly sleeved on the outer surface of each of the internal helical gears 205. A first wire is movably embedded between the relative inner walls of the heat exchanger body 1. Rod 208, the outer surface of the first lead screw 208 is threadedly connected to a movable box 210, the inner wall of the movable box 210 is movably embedded with a worm gear 211, one end of the worm gear 211 is fixedly connected to a first rotating shaft 212, the outer surface of the first rotating shaft 212 is fixedly sleeved with a first helical gear 219, the other side of the inner wall of the movable box 210 is movably embedded with a second rotating shaft 213, the outer surface of the second rotating shaft 213 is fixedly sleeved near the center with a first turbine 214, the outer surface of the second rotating shaft 213 is fixedly sleeved near one end with a first gear 215, the outer surfaces of multiple sliding plates 203 are all connected to the heat exchanger body. The inner wall of the heat exchanger body 1 is slidably connected, and the inner walls of multiple internal helical gears 205 mesh sequentially with the outer surfaces of multiple vertical teeth 202. On the other side of the heat exchanger body 1, near the edge of the inner wall, two sliding shafts 207 are fixedly connected. The outer surfaces of the two sliding shafts 207 are slidably connected with the inner walls of two sliding plates 203. The outer surface of the heat exchanger body 1 is fixedly connected to a first motor 221 by screws. The output shaft of the first motor 221 is fixedly embedded in the inner wall of one end of the first lead screw 208. A battery 222 is installed inside the movable box 210. The inner wall of the second helical gear 220 is connected to the movable box 210. The outer surfaces of the components are rotatably connected, and the outer surface of one of the slide plates 203 is fixedly connected to the outer surface of the mobile box 210. The second cleaning component 3 includes multiple first empty cylinders 301, each of which is movably embedded in one side of the inner wall of the mobile box 210. A rotating cylinder 302 is rotatably connected to one side of the outer surface of each of the multiple first empty cylinders 301. A first roller 303 is fixedly sleeved on the outer surface of each of the multiple first empty cylinders 301. A first track tooth 304 is movably meshed between the outer surfaces of the multiple first rollers 303. The outer surface of the second gear 218 meshes with the outer surface of the first track tooth 304.

[0023] In this embodiment, during the use of the integrated brazed high-pressure tubular heat exchanger, after the heat exchanger body 1 stops heat exchange and discharges the internal medium, the first motor 221 is started. The output shaft of the first motor 221 drives the first lead screw 208 to rotate. The first lead screw 208 drives the moving box 210 to move and the second helical gear 220 to rotate. The second helical gear 220 drives the first helical gear 219 to rotate. The first helical gear 219 drives the first rotating shaft 212 and the worm gear 211 to rotate. The worm gear 211 simultaneously drives the first turbine 214 and the second turbine 217 to rotate, which in turn drives the second rotating shaft 213 and the third rotating shaft 216 to rotate, causing the first gear 215 and the second gear 218 to rotate synchronously. The first gear 215 meshes with the toothed ring 204 on the inner wall of the ring 201, driving the ring 201 to rotate circumferentially. Simultaneously, as the moving box 210 moves, it drives the sliding plate 203 to slide along the inner wall of the heat exchanger body 1 and the sliding shaft 207. The ring 201 moves axially with the moving box 210. During the movement of the ring 201, the vertical teeth 202 on its outer surface mesh with multiple internal helical gears 205, driving the internal helical gears 205 and the first brush 206 on its outer surface to rotate at high speed. Under the combined motion of the ring 201 and the internal helical gears 205, the first brush 206 performs all-round scraping and cleaning of the inner wall of the heat exchanger body 1, removing the dirt attached to the inner wall. The second gear 218 drives the first track teeth 304 to rotate. The first track tooth 304 drives the first empty cylinder 301 to rotate; the first empty cylinder 301 drives the second empty cylinder 309 to rotate synchronously through a sliding connection with the second empty cylinder 309; similarly, the second empty cylinder 309 drives the third empty cylinder 311 to rotate, and the third empty cylinder 311 drives the fourth empty cylinder 312 to rotate; finally, the second brush 313 outside the second empty cylinder 309, the third brush 314 outside the third empty cylinder 311, and the fourth brush 315 outside the fourth empty cylinder 312 rotate synchronously with the empty cylinders, providing scraping power for intermittent cleaning. This device is equipped with a first cleaning component 2 and a second cleaning component 3. The first cleaning component 2 drives the ring 201 to move along the internal axial direction of the heat exchanger body 1 with the moving box 210. The device moves smoothly while rotating circumferentially, driving the internal helical gear 205 and the first brush 206 to rotate at high speed through the meshing of the vertical teeth 202. In the second cleaning assembly 3, the meshing transmission of the track teeth, gears, and rollers drives the second brush 313, third brush 314, and fourth brush 315 on all empty cylinders and outer surfaces to rotate synchronously. This achieves comprehensive scraping of the heat exchanger's inner wall, deep pipe walls, and corners—traditional cleaning blind spots—thoroughly removing attached dirt. This solves the problem that existing integrated tubular heat exchangers cannot be disassembled, resulting in stubborn cleaning blind spots in the deep pipe walls, pipe gaps, and corners, leading to incomplete cleaning of the integrated tubular heat exchanger.

[0024] like Figure 1-10As shown, a limiting shaft 209 is fixedly embedded between the inner walls of the heat exchanger body 1 near one edge. The inner wall of the movable box 210 is slidably connected to the outer surface of the limiting shaft 209. One end of the first rotating shaft 212 is movably embedded in the inner wall of the movable box 210. The outer surface of the first turbine 214 meshes with the outer surface of the worm gear 211. The outer surface of the first gear 215 meshes with the outer surface of the gear ring 204. A third rotating shaft 216 is movably embedded in the inner wall of the movable box 210. A second turbine 217 is fixedly sleeved on the outer surface of the third rotating shaft 216 near one end. The outer surface of the second turbine 217 meshes with the outer surface of the worm gear 211. A second gear 218 is fixedly sleeved on the outer surface of the third rotating shaft 216 near the other end. A second helical gear 220 is slidably connected to the outer surface of the first lead screw 208. The outer surface of the first helical gear 219 meshes with the outer surface of the second helical gear 220.

[0025] In this embodiment, when the integrated brazed high-pressure tubular heat exchanger is in use, the first motor 221 is started. The output shaft of the first motor 221 drives the first lead screw 208 to rotate. Since the movable box 210 is threadedly connected to the first lead screw 208, and the inner wall of the movable box 210 is slidably connected to the limiting shaft 209, the rotation of the first lead screw 208 drives the movable box 210 to move smoothly axially along the limiting shaft 209. Simultaneously, the rotation of the first lead screw 208 drives the second helical gear 220, which is slidably connected to it, to rotate. The inner wall of the second helical gear 220 is slidably connected to the movable box 210. The outer surface of the housing 210 is rotatably connected, allowing it to move with the movable housing 210 without affecting its rotation. The second helical gear 220 meshes with the first helical gear 219, thereby driving the first rotating shaft 212 and the worm gear 211 to rotate. The worm gear 211 simultaneously meshes with the first worm gear 214 and the second worm gear 217, respectively driving the second rotating shaft 213 and the third rotating shaft 216 to rotate, causing the first gear 215 and the second gear 218 to rotate synchronously. The first gear 215 meshes with the toothed ring 204 on the inner wall of the ring 201, driving the ring 201 to rotate circumferentially. At the same time, the movable housing 210... 0 is fixedly connected to one of the slide plates 203. When the moving box 210 moves, it drives the slide plate 203 to slide along the inner wall of the heat exchanger body 1 and the sliding shaft 207. The ring 201 moves axially with the moving box 210 through the sliding connection with the slide plate 203. The ring 201 drives multiple first brushes 206 to rotate at high speed. The second gear 218 meshes with the first track tooth 304, driving the first track tooth 304 to perform cyclic motion. The first track tooth 304 meshes with the first rollers 303 on the outer surface of multiple first empty cylinders 301, driving all the first rollers 303 and the first... The first empty cylinder 301 rotates synchronously; thereby driving the second brush 313 outside the second empty cylinder 309, the third brush 314 outside the third empty cylinder 311, and the fourth brush 315 outside the fourth empty cylinder 312 to rotate synchronously with the empty cylinder. The second cleaning component 3 and the first cleaning component 2 share the transmission power of the moving box 210, which is transmitted by the worm gear 211 and gear of the first cleaning component 2. There is no need to set up an independent drive structure, which simplifies the complexity of the overall device, ensures the transmission synchronization of the integrated brazed high-pressure tubular heat exchanger, and ensures the consistency of the cleaning effect.

[0026] like Figure 1-10As shown, a plurality of rotating drums 302 are each fixedly fitted with a second roller 305 on their outer surfaces. Second track teeth 306 are movably meshed between the outer surfaces of the plurality of second rollers 305. A second lead screw 307 is fixedly embedded at the center of one side of the inner wall of each of the plurality of rotating drums 302. A second empty cylinder 309 is threadedly connected to the outer surface of each of the plurality of second lead screws 307. A third lead screw 308 is rotatably connected to the inner wall of each of the plurality of second empty cylinders 309. The inner walls of the plurality of third lead screws 308 are slidably connected to the outer surfaces of the plurality of second lead screws 307. The outer surfaces of the plurality of second empty cylinders 309 are slidably connected to the inner walls of each of the plurality of first empty cylinders 301. A third empty cylinder 311 is threadedly connected to the outer surface of each of the plurality of third lead screws 308. The outer surfaces of the plurality of third empty cylinders 311 are slidably connected to the inner walls of each of the plurality of second empty cylinders 309. The inner walls of the three hollow cylinders 311 are rotatably connected to a fourth lead screw 310. The inner walls of the multiple fourth lead screws 310 are slidably connected to the outer surfaces of multiple third lead screws 308. The outer surfaces of the multiple fourth lead screws 310 are threadedly connected to a fourth hollow cylinder 312. The outer surfaces of the multiple fourth hollow cylinders 312 are slidably connected to the inner walls of the multiple third hollow cylinders 311. The outer surfaces of the multiple second hollow cylinders 309 are fixedly connected to a second brush 313. The outer surfaces of the multiple third hollow cylinders 311 are fixedly connected to a third brush 314. The outer surfaces of the multiple fourth hollow cylinders 312 are fixedly connected to a fourth brush 315. A second motor 316 is installed inside one side of the moving box 210. The output shaft of the second motor 316 is fixedly sleeved with a third gear 317. The outer surface of the third gear 317 meshes with the outer surface of the second track tooth 306.

[0027] In this embodiment, when the length of the second cleaning component 3 needs to be adjusted during the movement of the integrated brazed high-pressure tubular heat exchanger, the second motor 316 is started synchronously. The output shaft of the second motor 316 drives the third gear 317 to rotate. The third gear 317 meshes with the second track teeth 306, driving multiple second rollers 305 and the rotating drum 302 to rotate synchronously. The second lead screw 307, which is fixedly embedded in the inner wall of the rotating drum 302, rotates synchronously with the rotating drum 302. Through threaded engagement with the second empty cylinder 309, it drives the second empty cylinder 309 to extend and retract axially along the inner wall of the first empty cylinder 301. When the second motor 316 rotates forward, the empty cylinder extends. When the reverse direction is reversed, the empty cylinder contracts; the third lead screw 308 inside the second empty cylinder 309 rotates with the second empty cylinder 309, and drives the extension and retraction of the third empty cylinder 311 through threaded engagement; similarly, the fourth lead screw 310 inside the third empty cylinder 311 rotates with the third empty cylinder 311, driving the extension and retraction of the fourth empty cylinder 312, realizing the step-by-step extension and retraction adjustment of the multi-section empty cylinders. The second cleaning component 3 moves axially with the moving box 210. This device adopts a multi-section empty cylinder nested structure, and the lead screw is driven by the second motor 316 to realize the step-by-step extension and retraction adjustment of the empty cylinders. The length can be adjusted according to the width of the pipe gap inside the heat exchanger body 1, and it can accurately extend into narrow gaps, improving the applicability of this device.

[0028] The usage and working principle of this device: When the integrated brazed high-pressure tubular heat exchanger is in use, after the heat exchanger body 1 stops heat exchange and discharges the internal medium, the first motor 221 is started. The output shaft of the first motor 221 drives the first lead screw 208 to rotate. Since the moving box 210 is threadedly connected to the first lead screw 208, and the inner wall of the moving box 210 is slidably connected to the limiting shaft 209, the rotation of the first lead screw 208 drives the moving box 210 to move smoothly axially along the limiting shaft 209. Simultaneously, the rotation of the first lead screw 208 drives the second helical gear 220, which is slidably connected to it, to rotate. The inner wall of the second helical gear 220 is rotatably connected to the outer surface of the moving box 210, and can move with the moving box 210. Without affecting rotation, the second helical gear 220 meshes with the first helical gear 219, thereby driving the first rotating shaft 212 and the worm gear 211 to rotate. The worm gear 211 simultaneously meshes with the first turbine 214 and the second turbine 217, respectively driving the second rotating shaft 213 and the third rotating shaft 216 to rotate, causing the first gear 215 and the second gear 218 to rotate synchronously. The first gear 215 meshes with the gear ring 204 on the inner wall of the ring 201, driving the ring 201 to rotate circumferentially. At the same time, the moving box 210 is fixedly connected to one of the sliding plates 203. When the moving box 210 moves, it drives the sliding plate 203 to slide along the inner wall of the heat exchanger body 1 and the sliding shaft 207. The ring 201 slides along with the moving box 210 through its sliding connection with the sliding plate 203. During the axial movement of the ring 201, the vertical teeth 202 on its outer surface mesh with multiple internal helical gears 205, driving the internal helical gears 205 and the first brush 206 on its outer surface to rotate at high speed. Under the combined motion of the ring 201 and the internal helical gears 205, the first brush 206 performs all-around scraping and cleaning of the inner wall of the heat exchanger body 1, removing the dirt adhering to the inner wall. The second gear 218 meshes with the first track teeth 304, driving the first track teeth 304 to perform cyclic motion. The first track teeth 304 mesh with the first rollers 303 on the outer surface of multiple first empty cylinders 301, driving all the first rollers 303 and the first empty cylinders 301 to rotate synchronously. The first empty cylinders 301 interact with the second empty cylinders 309... The sliding connection drives the second empty cylinder 309 to rotate synchronously; similarly, the second empty cylinder 309 drives the third empty cylinder 311 to rotate, and the third empty cylinder 311 drives the fourth empty cylinder 312 to rotate; finally, the second brush 313 outside the second empty cylinder 309, the third brush 314 outside the third empty cylinder 311, and the fourth brush 315 outside the fourth empty cylinder 312 rotate synchronously with the empty cylinders, providing scraping power for intermittent cleaning. When the length of the second cleaning component 3 needs to be adjusted during the movement, the second motor 316 is started synchronously. The output shaft of the second motor 316 drives the third gear 317 to rotate. The third gear 317 meshes with the second track tooth 306, driving multiple second rollers 305 and the rotating cylinder 302 to rotate synchronously.The second lead screw 307, fixedly embedded in the inner wall of the rotating drum 302, rotates synchronously with the rotating drum 302. Through its threaded engagement with the second empty drum 309, it drives the second empty drum 309 to extend and retract axially along the inner wall of the first empty drum 301. When the second motor 316 rotates forward, the empty drum extends; when it rotates in reverse, the empty drum retracts. The third lead screw 308 inside the second empty drum 309 rotates with the second empty drum 309 and drives the extension and retraction of the third empty drum 311 through its threaded engagement. Similarly, the fourth lead screw 310 inside the third empty drum 311 rotates with the third empty drum 311, driving the extension and retraction of the fourth empty drum 312, thus realizing the step-by-step extension and retraction adjustment of multiple empty drum sections. The second cleaning component 3 moves axially with the moving box 210, while the brush rotates and extends and retracts simultaneously, achieving thorough cleaning of the gaps between multiple pipes inside the heat exchanger body 1 without dead angles. A slot can be opened on one side of the outer surface of the heat exchanger body 1, which can be connected to a flange and can charge the internal battery 222 when needed.
