Description

Technical Field

[0001] This invention relates to the field of carbon removal devices, specifically a carbon removal device based on high-pressure pulsed water jet. Background Technology

[0002] High-pressure pulsed water jets form high-speed pulsed water streams through specially designed nozzles, utilizing the triple action of water hammer effect (high-speed impact), shearing peel (complex surface treatment), and cavitation effect (bubble bursting impact) to remove carbon deposits. By adjusting the pressure (typically 100-280MPa) and pulse frequency (commonly 20-30Hz), it can precisely adapt to the cleaning needs of different materials, ensuring the safety of internal engine parts.

[0003] Currently, patent number CN202591153U discloses a robot-based high-pressure pulsed water jet jet aero-engine cleaning device. This device includes a pulse conversion device, a fixed base, a nozzle body, and an amplitude transformer. The pulse conversion device is integrated with the end of the nozzle body via the fixed base. One end of the amplitude transformer is connected to the central cavitation cavity of the nozzle body, and the other end of the amplitude transformer is connected to the pulse conversion device via a fixing component. However, this device has inherent shortcomings in cleaning efficiency and quality, especially when dealing with stubborn carbon deposits with high adhesion and complex structures. Its removal ability may be unsatisfactory, resulting in low cleaning efficiency and insufficient cleaning effect. Furthermore, its adaptability and treatment effect may be significantly limited when removing carbon deposits from components with complex geometries.

[0004] Therefore, a high-pressure pulsed water jet carbon removal device is proposed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a high-pressure pulsed water jet carbon removal device to solve the problem that the cleaning device may not have ideal cleaning ability when dealing with stubborn carbon deposits with high adhesion and complex structure, resulting in low cleaning efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a carbon removal device based on high-pressure pulsed water jet, comprising an inlet pipe, a jet assembly, a housing, and a nozzle body fixedly installed at one end of the inlet pipe, wherein a guide tube is fixedly installed at one end of the housing;

[0007] Also includes:

[0008] An auxiliary component is provided on the outside of the guide tube. The jet component includes a pulse unit and an adjustment unit. The adjustment unit is located on the side of the guide tube away from the outer shell.

[0009] The pulse unit includes a pulse pipe and a mounting plate fixedly installed in the middle of the pulse pipe. Two guide plates are symmetrically fixedly connected inside the pulse pipe, and side plates are symmetrically slidably installed inside the guide plates.

[0010] A sliding strip is fixedly connected to the side plate near the rotating rod, and two push blocks are fixedly connected to the outside of the rotating rod. The two push blocks are respectively located inside the two guide plates, and the sliding strip abuts against the push blocks.

[0011] The adjustment unit includes a connecting ring fixedly installed on the outside of the guide tube. A vertical plate is fixedly connected to the outside of the guide tube. A fixing rod is fixedly connected to one side of the vertical plate. A sliding sleeve is sleeved on the outside of the fixing rod. A fixing ring is fixedly connected to the bottom of the sliding sleeve. Pins are symmetrically fixedly connected to the outside of the fixing ring. The pins are slidably connected to the connecting ring. A rotating sleeve is also rotatably installed on the outside of the fixing rod. A nozzle is symmetrically fixedly installed on the outside of the rotating sleeve.

[0012] Preferably, the mounting plate has a rotating rod rotatably connected vertically inside, and the rotating rod is rotatably connected to both of the guide plates. The top end of the rotating rod passes through the upper guide plate and is fixedly connected to a top block. The guide plate has a transverse groove inside, and two sealing plates are symmetrically fixedly connected inside the groove. The pushing block is located in the middle of the two sealing plates, and the sliding strip is slidably connected to the sealing plates.

[0013] By adopting the above technical solution, the operator rotates the top block, which drives the rotating rod to rotate. The rotating rod drives the push block to rotate, and the long end of the push block squeezes the sliding strip. The sliding strip drives the side plate to move, making it easy for the side plate to slide out for use. This realizes multi-level, dynamic flow field control and energy form conversion processing of water flow.

[0014] Preferably, a bonding plate is fixedly connected to the bottom of the side plate, the bonding plate is slidably connected to the transverse groove, a spring is fixedly connected to the side of the bonding plate near the sealing plate, the spring is fixedly connected to the sealing plate, and the connecting ring is located at the end of the guide tube away from the outer shell.

[0015] By adopting the above technical solution, when the sliding bar moves, it will drive the side plate to move, the side plate will drive the bonding plate to move, the bonding plate will stretch the spring, and the sealing plate will play a sealing role.

[0016] Preferably, the fixing ring is sleeved on the outside of the guide tube, there are no fewer than three pins, a spring is fixedly connected between the fixing ring and the vertical plate, and connecting strips are symmetrically fixedly connected to the outside of the rotating sleeve, with the end of the connecting strip away from the rotating sleeve being fixedly connected to the nozzle.

[0017] By adopting the above technical solution, the operator can unscrew the fixing nut and the tightening bolt, and then rotate the rotating sleeve. The rotating sleeve drives the connecting strip and the nozzle to rotate, making it easier to rotate the clean nozzle to the position of the connecting ring.

[0018] Preferably, a fitting ring is fixedly connected to the side of the nozzle near the guide tube, the pin is slidably connected to the fitting ring, and a fixing nut is threadedly connected to the outside of the pin.

[0019] By adopting the above technical solution, the operator keeps the fitting ring and the connecting ring in contact, loosens the sliding sleeve, and the elastic force of the second spring drives the fixed ring and the sliding sleeve to return to their original position and slide. The fixed ring drives the pin to insert into the clean fitting ring.

[0020] Preferably, a clamping bolt is threaded to the side of the fixing rod away from the vertical plate, an outer sleeve is sleeved on the outside of the clamping bolt, the outer sleeve is slidably connected to the clamping bolt, and a pressure sleeve is fixedly connected to the bottom of the outer sleeve, the pressure sleeve is sleeved on the outside of the nozzle.

[0021] By adopting the above technical solution, the operator tightens the clamping bolt, which is screwed into the fixing rod. The clamping bolt pushes the outer sleeve to move, causing the outer sleeve to drive the clamping sleeve to press the clean nozzle.

[0022] Preferably, the auxiliary component includes a fixed cover fixedly installed on the outside of the guide tube, an air intake pipe fixedly installed on one side of the top of the fixed cover, an annular tube fixedly installed parallel inside the fixed cover, and a connecting pipe connecting adjacent annular tubes.

[0023] By adopting the above technical solution, the air inlet pipe is connected to the external hot air pipe, and the air outlet pipe is connected to the recovery pipe, so that the hot air can blow and heat the surface of the guide pipe.

[0024] Preferably, there are at least three annular tubes, the bottom end of the air inlet tube is connected to the top of the leftmost annular tube, the inner ring of the annular tube is uniformly fixedly installed with spray holes, and the bottom side of the fixed cover is fixedly installed with an air outlet tube.

[0025] By adopting the above technical solution, hot air is input into the annular pipe at other locations through the connecting pipe, and the hot air is sprayed out from the nozzle onto the surface of the guide pipe.

[0026] Preferably, the bottom end of the pulse pipe is connected to the nozzle body, the top end of the pulse pipe is connected to the bottom of the outer shell, a connecting pipe is fixedly installed at the other end of the outer shell, a pulse conversion device is fixedly installed on the side of the connecting pipe away from the outer shell, an amplitude transformer is fixedly installed inside the outer shell, a cavitation cavity is provided inside the guide tube near the outer shell, and a guide sleeve is fixedly installed inside the guide tube away from the outer shell.

[0027] By adopting the above technical solution, high-pressure water is first introduced into the nozzle body through the inlet pipe, then the water flows into the pulse pipe, and then the pre-treated fluid enters the shell and flows into the cavitation cavity inside the guide tube. The guide sleeve inside the guide tube concentrates the water at the center point, making the kinetic energy and pressure of the water increase instantaneously. At the same time, the pulse wave emitted by the pulse conversion device is transmitted to the amplitude transformer inside the shell, causing the front end of the amplitude transformer to generate high-frequency oscillation. The water jet of the mixed pulse is ejected from the nozzle and strikes the coated workpiece vertically.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. By adding a jet assembly to the nozzle body in the existing technical solution, the operator rotates the top block, which drives the rotating rod to rotate. The rotating rod drives the pushing block to rotate, and the long end of the pushing block presses against the sliding strip. The sliding strip moves the side plate, which in turn moves the bonding plate. The bonding plate stretches a spring, and the sealing plate provides a seal, thus facilitating the sliding out of the side plate for use. Through the cooperation of the pulse pipe, guide plate, and side plate, multi-stage, dynamic flow field control and energy form conversion of the water flow are achieved. The unique vertically symmetrical, tapering-to-expanding pipe section structure of the pulse pipe, combined with the mounting plate and guide plate, works together as the water flows through it. The integrated treatment method alters the internal energy distribution, velocity field, and pressure field of the water flow, causing preliminary, non-uniform pressure fluctuations (i.e., pre-pulse effect) to be generated inside the water flow before it enters the cavitation chamber and nozzle. This effectively enhances the excitation of cavitation nuclei and the initial generation of cavitation bubbles within the fluid. This pre-treated fluid carries stronger internal disturbances and higher cavitation potential, enabling it to more effectively couple with the pulse energy generated by the subsequent pulse conversion device. Ultimately, it generates a highly efficient composite energy water jet rich in high-energy cavitation bubbles and possessing specific pulse characteristics, thereby improving the ability to impact and break up carbon deposits, stripping efficiency, and cleaning thoroughness.

[0030] 2. When the nozzle becomes clogged and the cleaning efficiency decreases, the operator can unscrew the fixing nut, then the tightening bolt, and pull out the clamping sleeve to release the clamping sleeve from pressing on the clogged nozzle. Pulling the sliding sleeve causes the fixing ring and pin to slide, compressing the fixing ring and spring two, causing the pin to retract into the connecting ring. Then, rotating the rotating sleeve causes the connecting strip and nozzle to rotate, rotating the clean nozzle to the position of the connecting ring, so that the fitting ring fits against the connecting ring. Loosening the sliding sleeve allows the spring force of spring two to cause the fixing ring and sliding sleeve to return to their original position and slide. The fixing ring then causes the pin to insert into the clean fitting ring. Tightening the fixing nut limits and presses the fitting ring, and tightening the tightening bolt, which screws into the fixing rod, pushes the outer sleeve to move. The outer sleeve then causes the clamping sleeve to press on the clean nozzle, facilitating the replacement of a new nozzle. This improves rinsing efficiency and solves the problem that the cleaning device's removal capacity may be unsatisfactory when dealing with stubborn carbon deposits with high adhesion and complex structures, resulting in low cleaning efficiency.

[0031] 3. By setting auxiliary components, high-pressure water is first introduced into the nozzle body through the inlet pipe, and then the water flows into the pulse pipe. The water undergoes preliminary flow field disturbance and energy form conversion, generating a pre-pulse effect and initial cavitation disturbance. Then, the pre-treated fluid enters the shell and flows into the cavitation cavity inside the guide tube. The guide sleeve inside the guide tube concentrates the water at a central point, causing the kinetic energy and pressure of the water to increase instantaneously. At the same time, the pulse wave emitted by the pulse conversion device is transmitted to the amplitude transformer inside the shell, causing the front end of the amplitude transformer to oscillate at a high frequency. This high-frequency oscillation effect... In the water, the water is given high-speed kinetic energy under high pressure (high-pressure pulse jet and cavitation jet). The mixed pulse water jet is ejected from the nozzle and strikes the coated workpiece vertically. The operator connects the air inlet pipe to the external hot air duct and the air outlet pipe to the recovery pipe. The hot air enters the annular pipe through the air inlet pipe and is then fed into other annular pipes through the connecting pipe. The hot air is also ejected from the nozzle onto the surface of the guide pipe, which facilitates the heating of the water inside the guide pipe, thereby helping to improve the rinsing effect of the pulse water flow. Finally, the hot air is discharged and recovered through the air outlet pipe. Attached Figure Description

Detailed Implementation

[0047] 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.

[0048] Please see Figures 1-3 The present invention provides a technical solution: a carbon removal device based on high-pressure pulse water jet, including a water inlet pipe 1, a jet assembly 3, a housing 4 and a nozzle body 2 fixedly installed at one end of the water inlet pipe 1, and a guide tube 7 fixedly installed at one end of the housing 4.

[0049] The jet assembly 3 includes a pulse unit and an adjustment unit, with the adjustment unit located on the side of the guide tube 7 away from the housing 4.

[0050] The pulse unit includes a pulse pipe 31 and a mounting plate 32 fixedly installed in the middle of the pulse pipe 31. Two guide plates 35 are symmetrically fixedly connected inside the pulse pipe 31, and side plates 38 are symmetrically slidably installed inside the guide plates 35.

[0051] The distance between the left and right end faces of the guide plate 35 and the left and right end faces of the inner wall of the pulse pipe 31 is greater than 50 mm. The convex surface of the guide plate 35 faces the water outlet, and its concave surface faces the water inlet. The curvature of the guide plate 35 is 20 degrees.

[0052] A sliding strip 311 is fixedly connected to the side plate 38 near the rotating rod 33. Two push blocks 312 are fixedly connected to the outside of the rotating rod 33. The two push blocks 312 are located inside the two guide plates 35 respectively. The sliding strip 311 abuts against the push blocks 312.

[0053] The mounting plate 32 is vertically rotatably connected to a rotating rod 33. The rotating rod 33 is rotatably connected to both guide plates 35. The top of the rotating rod 33 passes through the upper guide plate 35 and is fixedly connected to a top block 34. The guide plate 35 has a transverse groove 36 inside. Two sealing plates 37 are symmetrically fixedly connected inside the groove 36. The push block 312 is located in the middle of the two sealing plates 37. The sliding strip 311 is slidably connected to the sealing plate 37.

[0054] A bonding plate 310 is fixedly connected to the bottom of the side plate 38. The bonding plate 310 is slidably connected to the transverse groove 36. A spring 39 is fixedly connected to the side of the bonding plate 310 near the sealing plate 37. The spring 39 is fixedly connected to the sealing plate 37.

[0055] The bottom end of the pulse pipe 31 is connected to the nozzle body 2, the top end of the pulse pipe 31 is connected to the bottom of the outer shell 4, the other end of the outer shell 4 is fixedly installed with a connecting pipe 5, the side of the connecting pipe 5 away from the outer shell 4 is fixedly installed with a pulse conversion device 6, the inside of the outer shell 4 is fixedly installed with an amplitude transformer, the inside of the guide pipe 7 is provided with a cavitation cavity on the side of the guide pipe 7 close to the outer shell 4, and the inside of the guide pipe 7 is fixedly installed with a guide sleeve on the side of the guide pipe 7 away from the outer shell 4.

[0056] Example 1: As Figures 4-8 As shown, the operator rotates the top block 34, which drives the rotating rod 33 to rotate. The rotating rod 33 drives the pushing block 312 to rotate, and the long end of the pushing block 312 presses the sliding strip 311. The sliding strip 311 drives the side plate 38 to move, and the side plate 38 drives the bonding plate 310 to move. The bonding plate 310 stretches the spring 39, and the sealing plate 37 plays a sealing role, thus facilitating the sliding out of the side plate 38 for use. Through the cooperation of the pulse pipe 31, the guide plate 35 and the side plate 38, multi-level dynamic flow field control and energy form conversion of water flow are realized.

[0057] The unique vertically symmetrical, tapering-to-expanding pipe section structure of the pulse pipe 31, combined with the mounting plate 32 and the guide plate 35, works together as the water flows through. This integrated treatment method alters the internal energy distribution, velocity field, and pressure field of the water flow, causing preliminary, non-uniform pressure fluctuations (i.e., pre-pulse effect) to be generated inside the water flow before it enters the cavitation chamber and nozzle 322. This effectively enhances the excitation of cavitation nuclei and the initial generation of cavitation bubbles inside the fluid. This pre-treated fluid carries stronger internal disturbances and higher cavitation potential, enabling it to more effectively couple with the pulse energy generated by the subsequent pulse conversion device 6. Ultimately, it generates a highly efficient composite energy water jet rich in high-energy cavitation bubbles and possessing specific pulse characteristics, improving the ability to impact and break up carbon deposits, the stripping efficiency, and the thoroughness of cleaning.

[0058] High-pressure water is first introduced into the nozzle body 2 through the inlet pipe 1. Then, the water flows into the pulse pipe 31, where it undergoes preliminary flow field disturbance and energy form conversion, generating a pre-pulse effect and initial cavitation disturbance. Next, the pre-treated fluid enters the interior of the outer shell 4 and flows into the cavitation cavity inside the guide pipe 7. The guide sleeve inside the guide pipe 7 concentrates the water at a central point, causing the kinetic energy and pressure of the water to increase instantaneously. At the same time, the pulse wave emitted by the pulse conversion device 6 is transmitted to the amplitude transformer inside the outer shell 4, causing the front end of the amplitude transformer to generate high-frequency oscillation. This high-frequency oscillation acts on the water, giving the water high-speed kinetic energy (high-pressure pulse jet and cavitation jet) on the basis of high pressure. The mixed pulse water jet is ejected from the nozzle 322 and strikes the coated workpiece vertically.

[0059] The adjustment unit includes a connecting ring 313 fixedly installed on the outside of the guide tube 7. A vertical plate 314 is fixedly connected to the outside of the guide tube 7. A fixing rod 315 is fixedly connected to one side of the vertical plate 314. A sliding sleeve 316 is sleeved on the outside of the fixing rod 315. A fixing ring 317 is fixedly connected to the bottom of the sliding sleeve 316. A pin 318 is symmetrically fixedly connected to the outside of the fixing ring 317. The pin 318 is slidably connected to the connecting ring 313. A rotating sleeve 320 is also rotatably installed on the outside of the fixing rod 315. A nozzle 322 is symmetrically fixedly installed on the outside of the rotating sleeve 320.

[0060] The connecting ring 313 is located at the end of the guide tube 7 away from the outer shell 4. The fixing ring 317 is sleeved on the outside of the guide tube 7. There are no less than three pins 318. A spring 319 is fixedly connected between the fixing ring 317 and the vertical plate 314. A connecting strip 321 is symmetrically fixedly connected to the outside of the rotating sleeve 320. The end of the connecting strip 321 away from the rotating sleeve 320 is fixedly connected to the nozzle 322.

[0061] A fitting ring 323 is fixedly connected to the side of the nozzle 322 near the guide tube 7. A pin 318 is slidably connected to the fitting ring 323. A fixing nut 324 is also threadedly connected to the outside of the pin 318.

[0062] A clamping bolt 325 is threadedly connected to the side of the fixing rod 315 away from the vertical plate 314. An outer sleeve 326 is sleeved on the outside of the clamping bolt 325. The outer sleeve 326 is slidably connected to the clamping bolt 325. A pressure sleeve 327 is fixedly connected to the bottom of the outer sleeve 326. The pressure sleeve 327 is sleeved on the outside of the nozzle 322.

[0063] Example 2: Figures 9-12 As shown, when nozzle 322 becomes clogged and cleaning efficiency decreases, the operator unscrews the fixing nut 324, then the tightening bolt 325, and pulls out the clamping sleeve 327. This releases the clamping sleeve 327 from pressing the clogged nozzle 322, and pulls the sliding sleeve 316. The sliding sleeve 316 drives the fixing ring 317 and the pin 318 to slide. The fixing ring 317 compresses the spring 319, causing the pin 318 to retract into the connecting ring 313. Then, the rotating sleeve 320 is rotated, which drives the connecting strip 321 and the nozzle 322 to rotate, rotating the clean nozzle 322 to the position of the connecting ring 313, so that the fitting ring 323 fits into the connecting ring 313.

[0064] Loosen the sliding sleeve 316, and the elastic force of the second spring 319 will drive the fixing ring 317 and the sliding sleeve 316 to return to their original sliding position. The fixing ring 317 will drive the pin 318 to insert into the clean fitting ring 323. Tighten the fixing nut 324 to limit and press the fitting ring 323, and tighten the clamping bolt 325. The clamping bolt 325 will be screwed into the fixing rod 315. The clamping bolt 325 will push the outer sleeve 326 to move. The outer sleeve 326 will drive the clamping sleeve 327 to press the clean nozzle 322, which will facilitate the replacement of the new nozzle 322. This will improve the rinsing efficiency and solve the problem that the cleaning device may not be able to remove stubborn carbon deposits with high adhesion and complex structure, resulting in low cleaning efficiency.

[0065] An auxiliary component 8 is provided on the outside of the guide tube 7. The auxiliary component 8 includes a fixed cover 81 fixedly installed on the outside of the guide tube 7. An air inlet pipe 82 is fixedly installed on one side of the top of the fixed cover 81. An annular pipe 83 is fixedly installed in parallel inside the fixed cover 81. A connecting pipe 84 connects adjacent annular pipes 83.

[0066] There are at least three annular pipes 83. The bottom end of the air inlet pipe 82 is connected to the top of the leftmost annular pipe 83. The inner ring of the annular pipe 83 is uniformly fixed with nozzles 85. The bottom side of the fixed cover 81 is fixed with an air outlet pipe 86.

[0067] Example 3: Figures 13-14As shown, the operator connects the air inlet pipe 82 to the external hot air duct and the air outlet pipe 86 to the recovery pipe. Hot air enters the annular pipe 83 through the air inlet pipe 82 and is then input into other annular pipes 83 through the connecting pipe 84. The hot air is also sprayed from the nozzle 85 onto the surface of the guide pipe 7, which facilitates the heating treatment of the water inside the guide pipe 7, thereby helping to improve the rinsing effect of the pulse water flow. Finally, the hot air is output and recovered through the air outlet pipe 86.

[0068] Working principle: When using this device, firstly, as... Figures 1-14 As shown, the operator rotates the top block 34, which drives the rotating rod 33 to rotate. The rotating rod 33 drives the pushing block 312 to rotate, and the long end of the pushing block 312 presses against the sliding strip 311. The sliding strip 311 drives the side plate 38 to move, making it easy for the side plate 38 to slide out for use. Through the cooperation of the pulse pipe 31, the guide plate 35, and the side plate 38, multi-stage, dynamic flow field control and energy form conversion of the water flow are achieved. The operator connects the air inlet pipe 82 to the external hot air pipe and the air outlet pipe 86 to the recovery pipe. Hot air enters the annular pipe 83 through the air inlet pipe 82, which facilitates the heating treatment of the water inside the guide pipe 7. High-pressure water is first introduced into the nozzle body 2 through the water inlet pipe 1, and then the water flows into the pulse pipe 31. Then, the pre-treated fluid enters the shell 4 and flows into the cavitation cavity inside the guide pipe 7. The guide sleeve inside the guide pipe 7 concentrates the water in the center. At a moment, the kinetic energy and pressure of the water increase instantaneously. At the same time, the pulse wave emitted by the pulse conversion device 6 is transmitted to the amplitude transformer inside the outer casing 4, causing the front end of the amplitude transformer to oscillate at a high frequency. This high frequency oscillation acts on the water, giving the water high-speed kinetic energy on the basis of high pressure (high-pressure pulse jet and cavitation jet). The mixed pulse water jet is ejected from the nozzle 322 and strikes the coated workpiece vertically. When the nozzle 322 becomes clogged and the cleaning efficiency decreases, the operator unscrews the fixing nut 324, then unscrews the clamping bolt 325, pulls out the clamping sleeve 327, and pulls the sliding sleeve 316 to rotate the clean nozzle 322 to the position of the connecting ring 313. The fixing nut 324 is tightened to limit and press the fitting ring 323, and the clamping bolt 325 is tightened. The outer casing 326 drives the clamping sleeve 327 to press the clean nozzle 322, making it easy to replace the new nozzle 322.
