Description

Technical Field

[0001] The invention belongs to the technical field of welding, in particular to an angle-adjustable welding processing device for a boiler. Background Art

[0002] As core equipment for industrial production and energy supply, the structural strength of boilers is directly related to operational safety and service life. During the boiler manufacturing process, in order to ensure that the welded joints have sufficient load-bearing capacity, a double-sided welding process is usually required. That is, welding operations are performed on both the inner and outer walls of the boiler to eliminate defects such as lack of fusion and porosity that may exist in single-sided welding, forming a uniform and dense weld.

[0003] For example, the patent with publication number CN119525903A discloses an angle-adjustable welding processing device for boilers, including a loading plate and a sliding frame slidably connected above the loading plate, a furnace body is provided above the loading plate, and the sliding frame includes a positioning assembly. This technology enables the positioning barrel to evenly clamp both sides of the furnace body in the horizontal direction by moving the first rollers at two locations and determining the vertical state of the frame-type slide by a vertical detector, thereby maximizing the stability of the furnace body when the furnace body is limited, thereby reducing the gap between the two furnace bodies after they are closed.

[0004] Although the above technology can be used to weld the outer wall of the boiler, it is not suitable for arc surface welding due to the limitation of the movement trajectory of the welding machine. At the same time, it cannot be used to weld inside the boiler.

[0005] At the same time, during the welding process, the welding smoke contains metal oxide particles, harmful gases and volatile organic compounds. Workers exposed to high-concentration smoke environment for a long time are very likely to develop respiratory diseases, metal fume fever and other occupational health problems, and even have safety hazards such as poisoning and suffocation due to the accumulation of harmful gases.

The filter cylinder in the circulation mechanism can effectively intercept impurities in the filtrate, which can not only protect the inner wall of the control cylinder, but also keep the filtrate clean and ensure reaction efficiency. The elastic arc plate of the dispersion mechanism produces high-frequency vibration under the impact of the filtrate, and disperses the liquid into fine droplets, which greatly increases the gas-liquid contact area, strengthens the turbulent mixing effect, and prolongs the action time of the droplets and smoke particles, making the smoke particles easier to be captured. At the same time, the knocking rod and the top pressure roller cooperate to further enhance the vibration of the arc plate, and the stirring blade continuously stirs the filtrate to prevent particle deposition, ensuring that the entire filtration process is efficient and stable, and effectively removing harmful components in welding smoke.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figures 1 to 11 As shown, the angle-adjustable welding processing device for a boiler described in the present invention includes a welding part, a supporting part, a moving part, a suction mechanism, a filtering mechanism, a circulation mechanism and a dispersion mechanism.

[0022] The welding part includes a mounting ring 4, a mounting plate 6 and a welding arm 7. The welding arm 7 is movably mounted on the outer wall of the mounting ring 4 through the mounting plate 6, wherein the mounting plate 6 is rotatably mounted on one side of the mounting ring 4. The welding arm 7 is a common welding robot arm used for welding, which is used to control the movement of the welding head.

[0023] When welding a large cylindrical workpiece (i.e., the furnace body of a boiler), first weld the two sections of the workpiece's exterior and preliminarily secure them. Then, extend the mounting ring 4 into the workpiece. Then, adjust the welding arm 7 to align the welding head with the weld. Then, start the welding machine, and then rotate the mounting plate 6 at a constant speed to control the movement of the welding head, thereby welding the interior of the workpiece.

[0024] The mounting ring 4 is controlled to move in the workpiece by a moving mechanism, and is fixed by a supporting part after movement. The moving part includes a moving ring 9, a moving motor 2, a mounting platform 8 and a control cylinder 12. The moving motor 2 is a common outer rotor type permanent magnet brushless DC hub motor, and the control cylinder 12 is a hydraulic cylinder.

[0025] The mounting platform 8 is slidably mounted on the outer wall of the moving ring 9 , the stator transverse axis of the moving motor 2 is fixedly connected to the mounting platform 8 , and the outer wall of the outer rotor of the moving motor 2 is provided with a rubber wheel.

[0026] The control cylinder 12 is fixedly mounted on the outer wall of the moving ring 9 , and the movable end is fixedly connected to the outer wall of the mounting platform 8 . The movement of the mounting platform 8 and the moving motor 2 is controlled by the control cylinder 12 .

[0027] The supporting portion includes a supporting ring 3, a telescopic cylinder 13 and a supporting plate 10. The telescopic cylinder 13 is a common hydraulic cylinder.

[0028] One side of the support ring 3 is fixedly connected to the outer wall of the mounting ring 4 , and the other side of the support ring 3 is fixedly connected to the outer wall of the moving ring 9 , thereby achieving a fixed connection between the support ring 3 , the mounting ring 4 and the moving ring 9 .

[0029] The telescopic cylinder 13 is fixedly mounted on the inner wall of the support ring 3 , and the movable end is fixedly connected to the outer wall of the support piece 10 . The support piece 10 is made of wear-resistant rubber material, and the movement of the support piece 10 is controlled by the telescopic cylinder 13 .

[0030] After the workpiece is fixed, the movable ring 9 is first moved to the inside of the workpiece by an external lifting device, and then the mounting table 8 and the movable motor 2 are controlled to move by the control cylinder 12 until the rubber outside the movable motor 2 fits with the inner wall of the workpiece. At this time, the external rotor of the movable motor 2 rotates to control the mounting ring 4 and the mounting plate 6 to move inside the workpiece until the welding arm 7 is located at the joint of the two workpieces, and then the welding head position is adjusted.

[0031] After the welding head position is calibrated, the support plate 10 is controlled to move by the telescopic cylinder 13 until the support plate 10 is tightly fitted with the inner wall of the workpiece to achieve support and fixation of the mounting ring 4. After fixation, the movable end of the control cylinder 12 is retracted and reset, and finally the mounting plate 6 is rotated at a constant speed to start the welding operation.

[0032] After the welding operation, the control cylinder 12 controls the rubber outside the mobile motor 2 to fit the inner wall of the workpiece, and then the telescopic cylinder 13 controls the support piece 10 to shrink. Finally, the mobile motor 2 reverses and controls the mobile ring 9 to withdraw from the inside of the workpiece to achieve annular welding of the inner wall of the workpiece.

[0033] As a preferred embodiment of the present invention, the filtering mechanism includes a storage box 16 and a partition plate 20. The inner cavity of the storage box 16 is used to store the filtrate, wherein the filtrate is a mixture of sodium hydroxide, sodium carbonate and low-concentration ammonia water. The smoke particles generated during welding are sucked into the inner cavity of the storage box 16 through the suction mechanism to neutralize the acidic gases (such as SO2 and NO2), adjust the pH to 8-10, and promote the precipitation of metal ions.

[0034] The partition plate 20 is fixedly mounted on the inner wall of the storage box 16. The inner cavity of the storage box 16 is divided into two independent chambers by setting the partition plate 20. A pressure relief pipe and a liquid injection port are provided on the outside of the storage box 16. The liquid injection port is used to replenish the filtered liquid and extract the waste liquid.

[0035] The benefit of providing the partition plate 20 to divide the inner cavity of the storage box 16 into two independent chambers is that when welding smoke is injected into one chamber, the other chamber filters the smoke. The two chambers are alternately injected with smoke to provide time for reaction so as to facilitate sufficient reaction.

[0036] The suction mechanism includes a suction pump 15 , a drive motor 14 , a three-way pipe 19 and a suction pipe 5 .

[0037] The driving motor 14 is fixedly mounted on the inner wall of the mounting ring 4 , and the output shaft is fixedly connected to the outer wall of the mounting plate 6 . The driving motor 14 controls the mounting plate 6 to rotate, thereby controlling the welding arm 7 to rotate.

[0038] The suction pump 15 is fixedly mounted on the outer wall of the mounting plate 6 , wherein when the mounting plate 6 rotates, the suction pump 15 is driven to rotate synchronously.

[0039] One end of the suction pipe 5 is fixedly connected to the outer wall of the mounting plate 6 , and the other end of the suction pipe 5 is connected to the input end of the suction pump 15 , so that during the welding process, the suction pump 15 sucks the smoke generated during welding inside the workpiece through the suction pipe 5 .

[0040] The connecting ring 1 is fixedly installed on the outer wall of the movable ring 9, and the storage box 16 is fixedly installed on the inner wall of the connecting ring 1. The output end of the suction pump 15 is connected to the inner cavity of the storage box 16 through a three-way pipe 19. An electronic valve is provided inside the three-way pipe 19, wherein the other two ends of the three-way pipe 19 are respectively connected to the two chambers inside the storage box 16 to facilitate alternate injection of gas into the two chambers. After the smoke particles are fully reacted, the pressure relief pipe exhausts and relieves the pressure.

[0041] As a preferred embodiment of the present invention, the circulation mechanism includes a control plug 24 and a control cylinder 21 having an output end and an input end, wherein both the output end and the input end of the control cylinder 21 are provided with a one-way valve with opposite conduction directions.

[0042] The control cylinder 21 is fixedly installed in the inner cavity of the storage box 16, and the control plug 24 is slidably installed in the inner cavity of the control cylinder 21. The outer wall of the control plug 24 is sealed and fits with the inner wall of the control cylinder 21. The control plug 24 slides back and forth, so that the filtered liquid in the inner cavity of the storage box 16 enters from the input end and is discharged from the output end.

[0043] During the process of the filtrate circulating in the storage box 16 and the inner cavity of the control cylinder 21, the filtrate is stirred. Stirring the filtrate can enhance the gas-liquid mass transfer efficiency, so that the harmful gases and particulate matter in the welding smoke can fully contact the liquid, accelerate the dissolution of the gas, and at the same time promote the mixing of chemical reagents and pollutants in the filtrate, maintain the uniformity of the reaction system to improve removal.

[0044] A feed cylinder 25 is elastically provided at the input end of the control cylinder 21 , the outer wall of the feed cylinder 25 is slidably fitted with the inner wall of the control cylinder 21 , and the feed cylinder 25 is connected to the control cylinder 21 via a spring.

[0045] A disassembly plate 18 is detachably mounted on the outer wall of the storage box 16 , and the disassembly plate 18 is connected to the storage box 16 by bolts.

[0046] The disassembly plate 18 is located on one side of the inner cavity of the storage box 16 and is rotatably installed with a mounting arm 36. The side wall of the mounting arm 36 is slidably installed with a mounting frame 26. During the rotation of the mounting arm 36, the mounting frame 26 is driven to rotate. At the same time, the mounting frame 26 can slide along the outer wall of the mounting arm 36 to adjust the position of the mounting frame 26.

[0047] A filter cartridge 37 is fixedly mounted on the inner wall of the mounting frame 26. The outer wall of the feed cartridge 25 slides in contact with the axial end of the filter cartridge 37. The filter cartridge 37 is made of filter cotton. During the reciprocating sliding of the control plug 24, the filter liquid is sucked through the feed cartridge 25. At this time, the filtered liquid enters the inner cavity of the filter cartridge 37. On the one hand, it can filter the filtered liquid entering the inner cavity of the control cartridge 21. On the other hand, it can absorb the particles in the filtered liquid into the inner cavity of the filter cartridge 37. After removing the disassembly plate 18, the solid particles inside the filter cartridge 37 can be removed.

[0048] When the control plug 24 slides back and forth, the filter cylinder 37 filters the filtrate entering the control cylinder 21, which can minimize the scratching of the inner cavity of the control cylinder 21 by metal particles and compounds. On the other hand, it can reduce the particulate matter content in the filtrate and maintain the reaction rate of the filtrate when smoke is filled again.

[0049] An arc-shaped piece 28 is fixedly installed at one end of the filter cylinder 37 away from the feed cylinder 25. The arc-shaped piece 28 is arranged at an angle, and multiple arc-shaped pieces 28 are arranged along the axis of the filter cylinder 37. The material of the arc-shaped piece 28 is the same as that of the filter cylinder 37. By arranging the arc-shaped piece 28, the particulate matter collected inside the filter cylinder 37 can be prevented from flowing back to the filtered liquid inside the storage box 16.

[0050] A float 27 is installed on the outer wall of the installation frame 26 through a connecting rope. The density of the float 27 is not higher than the density of the filtrate. After the filtrate is injected into the storage box 16, the float 27 floats up due to buoyancy. At this time, the float 27 pulls the installation frame 26 through the connecting rope.

[0051] When the suction pump 15 injects smoke particles into the storage box 16, the gas in the storage box 16 floats up, causing the liquid level to fluctuate. At this time, the mounting frame 26 fluctuates under the influence of the float 27. At this time, the feed cylinder 25 sucks different positions of the filter cylinder 37, thereby maintaining the filtration efficiency of the filter cylinder 37. At the same time, the floating of the gas when the smoke is filled can disturb the filtered liquid inside the storage box 16, which can not only lift up the particulate matter and improve the collection efficiency of the particulate matter, but also further improve the reaction efficiency through stirring.

[0052] As a preferred embodiment of the present invention, the dispersion mechanism includes an arc-shaped plate 31 and a mounting cylinder 29. The arc-shaped plate 31 is an elastic copper plate with a downward depression in the middle and arc-shaped ends raised upward.

[0053] The mounting cylinder 29 is elastically arranged in the inner cavity of the storage box 16 , the arc plate 31 is fixedly mounted on the outer wall of the mounting cylinder 29 , and a drain pipe 30 is fixedly mounted on the outer wall of the control cylinder 21 , which provides support for the mounting cylinder 29 through the control cylinder 21 .

[0054] A discharge nozzle facing the arc-shaped plate 31 is fixedly installed on the outer wall of the discharge pipe 30. The discharge pipe 30 is connected to the output end of the control cylinder 21. During the reciprocating sliding of the control plug 24, the filtrate is discharged toward the arc-shaped plate 31 through the discharge nozzle. The filtrate impacts the outer wall of the arc-shaped plate 31. At this time, the filtrate water column is scattered, which can enhance the turbulent mixing of the gas-liquid two phases by increasing the contact area between the droplets and the smoke.

[0055] A control motor 17 is fixedly mounted on the outer wall of the storage box 16. The output shaft of the control motor 17 extends to the inner cavity of the storage box 16 and is fixedly mounted with a control shaft 38. The control motor 17 drives the control shaft 38 to rotate. The control shaft 38 is a reciprocating threaded rod.

[0056] A transmission sleeve 23 is fixedly installed on the outer wall of the control plug 24, and the transmission sleeve 23 is connected to the control shaft 38 through internal and external threads. A guide frame is provided on the inner wall of the control cylinder 21, and a guide rod that slides with the guide frame is provided on the outer wall of the control plug 24. When the control shaft 38 rotates, the transmission sleeve 23 is driven to slide back and forth, and then the control plug 24 is driven to slide back and forth.

[0057] A mounting plate 32 is fixedly mounted on the inner wall of the storage box 16, and a mounting rod 41 is fixedly mounted on the outer wall of the mounting plate 32. The mounting rod 41 passes through the mounting cylinder 29 and is connected by an elastic member. The mounting plate 32 and the mounting rod 41 are both made of elastic materials, and the elastic member is a spring. When the filtered liquid impacts the curved plate 31, the curved plate 31 vibrates, and the vibration causes the filtered liquid to be more fully broken into fine droplets and evenly diffused, thereby strengthening the turbulent mixing of the gas-liquid two phases, prolonging its suspension time in the box, and increasing the duration of interaction with the smoke particles. At the same time, it causes the droplets to be evenly distributed in the box, covering a wider range of smoke flow paths, and reducing the probability of particle escape, thereby significantly improving the capture efficiency and purification effect of particulate matter in welding smoke.

[0058] A mounting block 33 is fixedly mounted on the inner wall of the storage box 16, and a knocking rod 11 for knocking the mounting plate 32 is elastically mounted on the inner wall of the mounting block 33. The mounting block 33 is located directly below the mounting plate 32, and the knocking rod 11 is connected to the mounting block 33 through a spring.

[0059] A transmission block 34 is fixedly installed at the bottom of the tapping rod 11, and an inclined block 40 is fixedly installed on the side wall of the transmission block 34. The transmission block 34 is pulled and then released, and the tapping rod 11 taps the mounting plate 32, thereby further improving the shaking intensity of the arc plate 31.

[0060] The outer wall of the control shaft 38 is fixedly mounted with a mounting bracket 22, and the outer wall of the mounting bracket 22 is rotatably mounted with a pressing roller 39 for pressing the inclined block 40. When the control shaft 38 rotates, the pressing roller 39 is driven to rotate by the mounting bracket 22, and the inclined block 40 is located within the rotation trajectory of the pressing roller 39, so that when the pressing roller 39 contacts the inclined block 40, the transmission block 34 is pulled. After the pressing roller 39 and the inclined block 40 are separated, the outer wall of the mounting block 33 is tapped by the tapping rod 11.

[0061] A stirring blade 35 is fixedly mounted on the side wall of the mounting frame 22. When the mounting frame 22 rotates, the stirring blade 35 stirs the filtrate to prevent particles from settling on the inner wall.

[0062] The above-mentioned front, back, left, right, up and down are all based on the Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
