Description

Technical Field

[0001] This invention relates to the field of grinding and dust removal equipment, and in particular to an integrated automatic grinding and dust removal equipment for weld seams used in transformer production. Background Technology

[0002] In the manufacturing process of power equipment such as power transformers, after welding, the weld area usually contains weld slag, spatter, undercut, and irregular weld excess (protrusions). If these surface defects are not effectively treated, the weld slag or protrusions will affect subsequent spraying operations. Fine grinding of the weld after welding is a key process to ensure product quality. Generally, an angle grinder is used with a resin grinding wheel or louvered blades, or finer sandpaper or special grinding discs are used to remove obvious weld slag and spatter, giving the transformer a smooth and uniform surface.

[0003] During the grinding process, dust is inevitably generated due to the intense friction between the abrasive and the workpiece. To effectively solve this problem, modern grinding equipment typically integrates a highly efficient dust collection and removal system. The powerful suction airflow generated by negative pressure can capture and remove most of the dust-laden gas, transporting it to the subsequent filtration and purification unit, ensuring a clean working environment and the health and safety of personnel.

[0004] Currently, exhaust ventilation systems are commonly used in the grinding and processing of welded seams in transformer shells to control dust dispersion. These systems typically employ multi-stage composite filtration and are equipped with air-blowing cleaning mechanisms to maintain the air permeability and filtration efficiency of the filter media, thereby extending the system's service life. However, the presence of multi-stage filtration units, the associated cleaning air paths, and large dust collection boxes makes the overall dust collector unit structure complex and space-consuming. Furthermore, the cleaning system itself requires regular maintenance, increasing operating costs. Summary of the Invention

[0005] This invention provides an integrated automatic weld grinding and dust removal device for transformer production, which can solve the problems of existing integrated automatic weld grinding and dust removal devices for transformer production, such as complex exhaust ventilation system structure, large space occupation, and high operating cost.

The water curtain assembly includes a water collection tank fixed to the machine body, a partition fixed inside the water collection tank, and a water spray nozzle on the partition. A spray pipe is fixed on the machine body and above the water collection tank. A conveying assembly is provided on the outside of the machine body. The conveying assembly is used to convey the gas captured by the first dust suction hood to the area below the water spray nozzle. The water spray nozzle forms a water curtain to purify the conveyed dust-laden gas before it is discharged.

[0007] Preferably, the bottom of the machine body is provided with a sedimentation and filtration assembly for sedimentation and filtration of the sewage discharged from the water collection tank, and a circulation assembly is provided on one side of the machine body for conveying the water treated by the sedimentation and filtration assembly to the spray pipe.

[0008] Preferably, the moving stage assembly includes a processing table located below the grinding head, a first drive assembly located below the processing table, and a second drive assembly located on the processing table. The first drive assembly is used to drive the processing table to move horizontally, and the second drive assembly is used to drive the transformer placed on the processing table to rotate.

[0009] Preferably, the control component includes a fourth drive component disposed on the machine body and a third drive component disposed on the fourth drive component. The third drive component is used to drive the grinding head to rotate, and the fourth drive component is used to drive the third drive component and the grinding head to move longitudinally.

[0010] Preferably, the vacuuming assembly further includes a connecting pipe fixed to the mounting plate, a connecting pipe communicating with the connecting pipe, and a connecting hose communicating with the connecting pipe, wherein the first vacuuming hood is fixed to one end of the connecting pipe.

[0011] Preferably, the conveying assembly includes a fan fixed to the outside of the machine body, a dust suction pipe fixed to the fan inlet, and an air outlet pipe fixed to the fan outlet. A second conveying pipe extending into the inside of the machine body is fixed to the dust suction pipe. The connecting hose is connected to the second conveying pipe. The air outlet pipe extends into the water collection tank. An exhaust pipe is fixed inside the water collection tank on the side opposite to the air outlet pipe.

[0012] Preferably, the sedimentation filtration assembly includes a sedimentation tank fixed to the bottom of the machine body and a plurality of sedimentation chambers disposed inside the sedimentation tank. Each pair of adjacent sedimentation chambers are connected by an overflow port. Each sedimentation chamber is provided with a drain pipe at the bottom. The bottom of each sedimentation chamber is a conical structure. Each drain pipe is provided with a valve. A liquid collection hopper is fixed to the bottom of the water collection tank. A water delivery pipe is fixed to the bottom of the liquid collection hopper. The water delivery pipe is located above the first sedimentation chamber.

[0013] Preferably, the circulation assembly includes a delivery pump located on one side of the machine body and a liquid extraction pipe fixed to the inlet of the delivery pump. The liquid extraction pipe extends to the supernatant in the final sedimentation chamber, and the spray pipe is connected to the outlet of the delivery pump.

[0014] Preferably, the circulation assembly includes a delivery pump located on one side of the machine body and a liquid extraction pipe fixed to the inlet of the delivery pump.

[0016] This invention provides an integrated automatic weld grinding and dust removal device for transformer manufacturing, which has the following beneficial effects: 1. During grinding operations, the spray pipes spray water evenly downwards, forming a continuous water curtain at the machine's opening. This water curtain effectively seals off the work area, preventing the escape of dust-laden gas generated during grinding and improving environmental containment while maintaining visibility. The dust-laden gas collected by the first dust hood is guided by the conveying assembly to the water collection tank. The tank not only receives the sprayed water falling from the spray pipes but also uses internal baffles and nozzles to create multiple water curtain barriers. As the dust-laden gas travels through the water collection tank, it continuously passes through these water curtains, allowing dust particles to be adsorbed and trapped by the water, thus purifying the gas. The purified gas can then be safely discharged. Compared to the complex multi-stage filtration systems and high-pressure air blowing structures commonly used in traditional grinding and dust removal equipment, the integrated design of water curtain sealing and multi-stage water washing not only simplifies the system structure and reduces the space occupied by the equipment, but also avoids cumbersome operations such as filter material replacement and air circuit maintenance. While ensuring efficient dust removal, it improves the practicality and economy of the equipment.

[0017] 2. Wastewater in the collection tank flows into the primary sedimentation chamber through the collection hopper and water delivery pipe. Wastewater flows through multiple sedimentation chambers and overflow outlets in sequence. Sludge settles at the bottom of the cone and is periodically discharged through the sewage pipe. The supernatant is recycled to the spray pipe by the delivery pump for reuse. Wastewater can be recycled after simple filtration treatment, realizing the sustainable use of water resources.

[0018] 3. In the grinding area, a first dust suction hood is installed at the grinding head, covering the area near the grinding point. This hood efficiently captures dust as it is generated, achieving better source control and improving dust removal efficiency. Simultaneously, a second dust suction hood is added to the side of the machine body. This second hood is connected to the suction pipe via the first delivery pipe, allowing for better collection of diffused dust. Attached Figure Description

[0021] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] like Figures 1 to 8 As shown in the figure, an integrated automatic weld grinding and dust removal device for transformer production provided by an embodiment of the present invention includes a body 1, a moving platform assembly 2 on the body 1, a grinding head 8 above the moving platform assembly 2, a control assembly 3 on the body 1 for adjusting the position of the grinding head 8, a dust suction assembly 4 at the grinding head 8, the dust suction assembly 4 including a first dust suction hood 41 coaxially arranged with the grinding head 8, a water curtain assembly 6 at the opening of the body 1, the water curtain assembly 6 including a water collection tank 61 fixed on the body 1, a partition 62 fixed inside the water collection tank 61, and a water spray nozzle 63 on the partition 62, a spray pipe 17 fixed on the body 1 and above the water collection tank 61, the spray pipe 17 having a plurality of downward-facing spray nozzles evenly arranged on it, and a conveying assembly 5 on the outside of the body 1, the conveying assembly 5 for conveying the gas captured by the first dust suction hood 41 to below the water spray nozzle 63, the water spray nozzle 63 forming a water curtain to purify the conveyed dust-laden gas before discharging it.

[0023] During the grinding operation, spray pipe 17 sprays water evenly downwards, forming a continuous water curtain at the opening of the machine body 1. The water curtain effectively seals off the working area, helping to suppress the escape of dust-laden gases generated during grinding, thus improving environmental enclosure while ensuring operational visibility. During the loading and unloading phases, spray pipe 17 can be temporarily shut off.

[0024] In the grinding area, a first dust suction hood 41 is installed at the grinding head 8. The first dust suction hood 41 covers the area near the grinding point and can efficiently capture dust when it is generated, thus achieving better source control and improving dust removal efficiency. The dust-laden gas collected by the first dust suction hood 41 is guided to the inside of the water collection tank 61 by the conveying component 5. The water collection tank 61 not only receives the spray water falling from the spray pipe 17, but also forms multiple water curtain barriers by allowing water to flow down through the internal baffle 62 and water inlet 63 structure. As the dust-laden gas passes through the water collection tank 61, it needs to continuously pass through these water curtains, which allows the dust particles to be adsorbed and trapped by the water, thereby purifying the gas. The purified gas can be safely discharged, while the wastewater can be recycled after simple filtration treatment, achieving sustainable use of water resources.

[0025] Compared to the complex multi-stage filtration systems and high-pressure air blowing structures commonly used in traditional grinding and dust removal equipment, this embodiment simplifies the system structure and reduces the space occupied by the equipment through the integrated design of water curtain sealing and multi-stage water washing. It also avoids cumbersome operations such as filter material replacement and air circuit maintenance, thus improving the practicality and economy of the equipment while ensuring efficient dust removal.

[0026] In some specific implementation plans, such as Figure 3 , Figure 4 and Figure 8 As shown, the moving table assembly 2 includes a processing table 23 located below the grinding head 8, a first drive assembly 21 located below the processing table 23, and a second drive assembly 22 located on the processing table 23. The first drive assembly 21 is used to drive the processing table 23 to move horizontally, and the second drive assembly 22 is used to drive the transformer placed on the processing table 23 to rotate. The first drive assembly 21 includes two fixed plates 211 fixed to the machine body 1, a first lead screw 212 rotatably connected between the fixed plates 211, and a first motor 213 fixed to one of the fixed plates 211. One end of the first lead screw 212 is fixedly connected to the output shaft of the first motor 213, and the processing table 23 is threadedly connected to the first lead screw 212. Two guide rails are fixed on the machine body 1 near the processing table 23, and slide rails slide on each guide rail. The processing table 23 is fixed on the slide rails. The second drive assembly 22 includes a rotating shaft 222 rotatably connected to the processing table 23, a turntable 221 fixed to the top of the rotating shaft 222, a second motor 223 fixed to the bottom of the processing table 23, and two pulleys 224. The two pulleys 224 are respectively fixed to the output shaft of the second motor 223 and the bottom of the rotating shaft 222, and the two pulleys 224 are connected by belt drive.

[0027] When the first motor 213 starts, it drives the first lead screw 212 to rotate, thereby causing the processing table 23 to move precisely horizontally along the slide rail. When the second motor 223 works, it drives the rotating shaft 222 and the turntable 221 on it to rotate through the transmission of the pulley 224 and the belt, thereby realizing the rotational movement of the transformer workpiece placed on the turntable 221, which facilitates the grinding head 8 to grind the welds at different positions. The first drive assembly 21 realizes the precise adjustment of the front and back position of the transformer workpiece, and works in conjunction with the second drive assembly 22 to realize the rotation of the workpiece itself. The two work together, in conjunction with the movement of the grinding head 8, to better complete the automated grinding operation of the transformer welds.

[0028] In some specific implementation plans, such as Figure 3 and Figure 4As shown, the control component 3 includes a fourth drive component 32 mounted on the machine body 1 and a third drive component 31 mounted on the fourth drive component 32. The third drive component 31 drives the grinding head 8 to rotate, and the fourth drive component 32 drives the third drive component 31 and the grinding head 8 to move longitudinally. The fourth drive component 32 includes a mounting bracket 321 fixed on the machine body 1, a second lead screw 322 rotatably connected to the mounting bracket 321, a moving plate 324 threadedly connected to the second lead screw 322, and a fourth motor 323 fixed on the mounting bracket 321. The second lead screw 322 is fixedly connected to the output shaft of the fourth motor 323. The third drive component 31 includes a third motor 312 fixed on the moving plate 324, a mounting plate 311 fixed on the third motor 312, and a coupling 313 rotatably connected to the mounting plate 311. One end of the coupling 313 is fixedly connected to the output shaft of the third motor 312, and the grinding head 8 is fixedly mounted on the other end of the coupling 313.

[0029] The control component 3 is used to adjust the spatial position of the grinding head 8. The third motor 312 drives the grinding head 8 to rotate through the coupling 313 to grind the weld. The second lead screw 322 is driven by the fourth motor 323, which drives the moving plate 324 to move longitudinally. The movement of the moving plate 324 drives the grinding head 8 to move up and down to grind the transformer weld more thoroughly.

[0030] In some specific implementation plans, such as Figure 1 , Figure 3 and Figure 7 As shown, the dust collection assembly 4 also includes a connecting pipe 44 fixed on the mounting plate 311, a connecting pipe 42 connected to the connecting pipe 44, and a connecting hose 43 connected to the connecting pipe 42. A first dust collection hood 41 is fixed on one end of the connecting pipe 44, and a coupling 313 is coaxially disposed inside the connecting pipe 44, so that the first dust collection hood 41 can cover the grinding area of ​​the grinding head 8. A second dust collection hood 9 is embedded on the side of the body 1. The second dust collection hood 9 is connected to the dust collection pipe 52 through the first conveying pipe 10. A gap is set between the second dust collection hood 9 and the spray pipe 17 to avoid disturbing the water sprayed from the spray pipe 17 when the second dust collection hood 9 is sucking air.

[0031] The dust collection component 4 is located at the grinding head 8 to collect dust generated during grinding in real time. The first dust collection hood 41 is coaxially arranged with the grinding head 8 and fixed to the mounting plate 311 through the connecting pipe 44, which can better cover the grinding area of ​​the grinding head 8. The coupling 313 is coaxially arranged inside the connecting pipe 44 to ensure that dust collection and grinding are carried out simultaneously. After the connecting hose 43 is connected to the connecting pipe 42, the first dust collection hood 41 and the dust collection pipe 52 are connected, and the dust-laden gas is transported to the conveying component 5.

[0032] Another dust suction hood is added to the side of the body 1. The second dust suction hood 9 is connected to the dust suction pipe 52 through the first delivery pipe 10 and is used to collect diffused dust.

[0033] In some specific implementation plans, such as Figure 1 and Figure 6 As shown, the conveying assembly 5 includes a fan 51 fixed to the outside of the body 1, a dust suction pipe 52 fixed to the inlet of the fan 51, and an air outlet pipe 53 fixed to the outlet of the fan 51. A second conveying pipe 11 extending into the body 1 is fixed on the dust suction pipe 52. A connecting hose 43 is connected to the second conveying pipe 11. The air outlet pipe 53 extends into the water collection tank 61. An exhaust pipe 14 is fixed inside the water collection tank 61 on the side opposite to the air outlet pipe 53.

[0034] The dust-laden gas captured by the first dust hood 41 and the second dust hood 9 is transported to the water collection tank 61 through the suction pipe 52 and the fan 51. As the dust-laden gas flows below the water spray nozzle 63, it is purified by the water curtain and discharged through the exhaust pipe 14. While the dust-laden gas is purified and discharged inside the water collection tank 61, water is kept flowing at the openings of the water spray nozzle 63 and the water pipe 19, and a liquid level is maintained inside the partition 62 and the liquid collection hopper 18, allowing the dust-laden gas to be discharged more effectively through the exhaust pipe 14.

[0035] In some specific implementation plans, such as Figure 3 , Figure 4 and Figure 5 As shown, the bottom of the machine body 1 is provided with a sedimentation and filtration assembly 7, which is used to sediment and filter the sewage discharged from the water collection tank 61. The sedimentation and filtration assembly 7 includes a sedimentation tank 71 fixed to the bottom of the machine body 1 and multiple sedimentation chambers 72 located inside the sedimentation tank 71. Each pair of adjacent sedimentation chambers 72 are connected by an overflow port 73. Each sedimentation chamber 72 is provided with a drain pipe 74 at the bottom. The bottom of each sedimentation chamber 72 is designed with a conical structure. Each drain pipe 74 is equipped with a valve. A liquid collection hopper 18 is fixed to the bottom of the water collection tank 61. A water delivery pipe 19 is fixed to the bottom of the liquid collection hopper 18. The water delivery pipe 19 is located above the first sedimentation chamber 72. A gap is set between the partition plate 62 and the top of the water collection tank 61. The gap is set to prevent water from dripping onto the partition plate 62 and splashing out of the water collection tank 61. The height of the water curtain formed by the spray pipe 17 is sufficient to allow the opening of the machine body 1 to facilitate the loading and unloading of transformer workpieces on the processing table 23.

[0036] Wastewater inside the collection tank 61 is transported to the primary sedimentation chamber 72 via the collection hopper 18 and the water supply pipe 19, forming a multi-stage sedimentation and filtration structure inside the collection tank 61. The sedimentation chambers 72 are connected sequentially via overflow ports 73 and are used to treat the wastewater discharged from the collection tank 61. The bottom of the sedimentation chamber 72 is conical and fitted with a drain pipe 74 with a valve to facilitate sludge discharge.

[0037] In some specific implementation plans, such as Figure 1 and Figure 2As shown, a circulation component is provided on one side of the machine body 1. The circulation component is used to transport the water treated by the sedimentation and filtration component 7 to the spray pipe 17. The circulation component includes a delivery pump 13 located on one side of the machine body 1 and a liquid extraction pipe 12 fixed on the inlet of the delivery pump 13. The liquid extraction pipe 12 extends to the supernatant of the final sedimentation chamber 72. The spray pipe 17 is connected to the outlet of the delivery pump 13.

[0038] The circulation component is used to realize the recycling of water resources. The liquid extraction pipe 12 extends to the supernatant of the final sedimentation chamber 72, and the transfer pump 13 delivers the purified water to the spray pipe 17 to form a water circulation system.

[0039] In some specific implementation plans, such as Figure 2 and Figure 3 As shown, a cylinder 15 is fixedly mounted on the top wall of the machine body 1, and a pressure plate 16 is fixedly mounted on the drive shaft of the cylinder 15. The cylinder 15 drives the pressure plate 16 to move downward and contact the transformer, which is used to stabilize the transformer workpiece during the grinding process.

[0040] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: The transformer workpiece to be ground is placed on the turntable 221. The cylinder 15 is activated, driving the pressure plate 16 to press down and stably press the workpiece onto the turntable to prevent displacement during the grinding process. The third motor 312 drives the grinding head 8 to rotate at high speed through the coupling 313 to grind the weld.

[0041] During the grinding process, the workpiece position is adjusted. For horizontal front-to-back adjustment, the first motor 213 drives the first lead screw 212 to rotate, causing the processing table 23 to move laterally along the guide rail, adjusting the workpiece's front-to-back position. When the workpiece rotates, the second motor 223 drives the rotating shaft 222 via the pulley 224 and belt, causing the turntable 221 and the workpiece to rotate, aligning the welds at different positions sequentially with the grinding head. For longitudinal adjustment, the fourth motor 323 drives the second lead screw 322 to rotate, causing the moving plate 324 and the grinding head 8 to move vertically up and down, adapting the grinding head 8 to the weld height for grinding.

[0042] During grinding, the first dust hood 41 near the grinding head 8 captures the generated dust in real time, and the dust-laden gas enters the second conveying pipe 11 through the connecting pipe 44, connecting pipe 42, and connecting hose 43. At the same time, the second dust hood 9 on the side wall of the machine body 1 collects the scattered dust and flows into the suction pipe 52 through the first conveying pipe 10. The fan 51 draws the dust-laden gas into the suction pipe 52 and delivers it to the inside of the water collection tank 61 through the air outlet pipe 53.

[0043] The transfer pump 13 pumps the supernatant from the final sedimentation chamber 72 into the spray pipe 17 via the extraction pipe 12. The spray pipe 17 sprays water downwards, forming a water curtain at the opening of the machine body 1, which can better seal the working area and reduce dust escape. After the dust-laden gas enters the water collection tank 61 from the exhaust pipe 53, it passes through the multiple water curtains formed by the water spray nozzles 63 on the partition 62. The dust particles are adsorbed and trapped by the water flow, and the purified gas is discharged through the exhaust pipe 14.

[0044] Wastewater in the collection tank 61 flows into the primary sedimentation chamber 72 through the collection hopper 18 and the water conveying pipe 19. Wastewater flows through the multi-stage sedimentation chamber 72 through the overflow port 73 in sequence. Sludge settles at the bottom of the cone and is periodically discharged through the sewage pipe 74. The supernatant is recovered by the transfer pump 13 to the spray pipe 17 for recycling.

[0045] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
