Abstract

This invention relates to the field of welding fume purification technology, and discloses a welding fume purification system and method for memory module manufacturing. The welding fume purification system for memory module manufacturing includes a welding equipment body with several suction hoods symmetrically distributed on the body. A horizontal pipe is connected to the outlet of each suction hood, and a first vertical pipe is located at the bottom of the horizontal pipe. This welding fume purification system for memory module manufacturing extends the residence time of the fume in the first vertical pipe through staggered diversion plates, allowing it to fully contact the cooled pipe wall and initially reduce the fume temperature. This significantly slows down the oxidation reaction rate between metal oxides and the filter cartridge substrate, reducing the degree of filter cartridge corrosion and extending its service life. Simultaneously, the stable low-temperature environment prevents the filter cartridge from failing to seal due to thermal expansion and contraction, ensuring filtration accuracy while effectively preventing secondary pollution caused by leakage of unfiltered fume.

Description

Technical Field

[0001] This invention relates to the field of welding fume purification technology, and in particular to a welding fume purification system and method applied to memory module manufacturing. Background Technology

[0002] In the memory module manufacturing process, soldering is one of the core steps, but the resulting soldering fumes have become a critical issue affecting the production environment and the health of workers. Memory module soldering often uses lead-free solder, which releases complex fumes containing rosin acid, resin acid, and metal oxides under high temperatures. These fumes can easily enter the human body through the respiratory tract, and long-term exposure may cause lung damage, respiratory inflammation, and other health risks. While fume purification devices are typically used to remove fumes during soldering, existing fume purification devices have the following drawbacks:

[0003] Existing fume purification devices first create a negative pressure field by using a directional suction hood to efficiently capture the fume generated in the welding area and guide it into a closed pipeline system. Then, the fume flows through the core filtration unit, where the particles are separated from the gas through the interception of the filter cartridge, inertial collision, and diffusion effects. Finally, the purified gas is pressurized by an induced draft fan and discharged into the atmosphere through a qualified emission port, completing the entire purification cycle. However, the fumes generated during memory module soldering have significant unique characteristics, causing dual damage to the filter cartridge. On the one hand, during soldering, the metal base material and lead-free solder melt at high temperatures, generating fumes with temperatures reaching 120-180℃. This high-temperature environment accelerates the chemical reaction between metal oxides in the fumes and the filter cartridge substrate, leading to oxidation and corrosion of the filter cartridge. Specifically, this manifests as a decrease in the strength of the substrate fibers and damage to the integrity of the coating. Long-term operation will reduce the filtration accuracy of the filter cartridge, resulting in the loss of its core filtration capacity. On the other hand, the metal particles in the fumes have a high specific surface area and adsorption capacity. Under the influence of airflow inside the filter cartridge, they easily form a dense dust cake on the surface of the filter material. As the operating time increases, the air resistance of the filter cartridge gradually increases, not only causing a decrease in system airflow but also requiring periodic shutdowns to replace the filter cartridge, directly affecting production efficiency. Furthermore, filter cartridge blockage can also trigger local airflow eddies, leading to leakage of unfiltered fumes and causing secondary pollution. Summary of the Invention

[0004] Given that existing technologies generate welding fumes containing metal oxides, which accelerate the oxidation and corrosion of filter cartridges, and that metal particles in the fumes easily form dust cakes that clog the filter cartridges, requiring machine shutdown for replacement, thus affecting efficiency and potentially causing secondary pollution, a welding fume purification system and method for memory module manufacturing is proposed.

[0005] This application provides a welding fume purification system for memory module processing. Its purpose is to: prevent filter cartridges from being blocked by accelerated oxidation and corrosion due to high temperature and the formation of dust cakes by metal particles; reduce downtime for filter cartridge replacement; prevent secondary pollution caused by leakage of unfiltered fumes; ensure the filtration accuracy and lifespan of the filter cartridges; and improve purification efficiency and effective working time for welding processes.

[0006] The technical solution of the present invention is as follows: a welding fume purification system for memory module processing, comprising a welding equipment body, a plurality of suction hoods symmetrically distributed on the welding equipment body, a horizontal pipe being provided at the air outlet of the plurality of suction hoods, a first vertical pipe being provided at the bottom of the horizontal pipe, a second vertical pipe being provided at the bottom of the first vertical pipe, a purification cylinder being provided at the bottom of the second vertical pipe, a filter cylinder being provided inside the purification cylinder, two air outlet pipes symmetrically distributed on the purification cylinder, a fan being provided inside the two air outlet pipes, and a cooling and cleaning unit provided on the welding equipment body;

[0007] The cooling and cleaning unit includes a cooling component on the first vertical pipe and a cleaning component on the main body of the welding equipment. The cooling component includes a cooling assembly on the first vertical pipe and a driving assembly and a rotating assembly on the second vertical pipe.

[0008] The cooling component is used to cool the welding fumes entering the first vertical pipe, and the cleaning component is used to clean the particulate matter on the inner wall of the filter cartridge.

[0009] The cooling assembly includes a cooling cylinder mounted on a first vertical pipe. A liquid outlet pipe is located on one side of the top of the cooling cylinder, and a liquid inlet pipe is located on one side of the bottom of the cooling cylinder. A push ring is also mounted on the first vertical pipe. The push ring is slidably and sealed to the inside of the cooling cylinder. Several through holes are arranged in a circular array on the push ring. A cover plate is located on the top of the through holes on the push ring. A baffle ring is located at the bottom of the inside of the first vertical pipe. Several conical guide plates are evenly distributed on the top of the baffle ring. Arc-shaped openings are alternately arranged on the conical guide plates. The conical guide plates are fixedly connected to each other.

[0010] Furthermore, the drive assembly includes a reciprocating spiral groove on the second vertical tube, and a nut is also provided on the second vertical tube.

[0011] Furthermore, the rotating assembly includes a rotating shaft disposed inside the purification cylinder, a turbine blade disposed on the rotating shaft, a rotating plate disposed on the top of the rotating shaft, and the rotating plate being fixedly connected to the inner wall of the second vertical pipe.

[0012] Furthermore, the cleaning component includes a cleaning assembly disposed inside the filter cartridge, a pushing assembly disposed on the cleaning assembly, a limit rotation assembly disposed between the cleaning assembly and the pushing assembly, a one-way rotation assembly disposed on the cleaning assembly, and a cleaning assembly disposed at the bottom of the filter cartridge;

[0013] The cleaning assembly includes a reciprocating screw disposed inside the filter cartridge. The top of the reciprocating screw is fixedly connected to a rotating shaft. Two smooth rods are also symmetrically distributed inside the filter cartridge and are fixedly connected to the purification cartridge. A threaded sleeve is disposed outside the reciprocating screw and is slidably connected to the two smooth rods respectively. Several rotating shafts are arranged in a ring array on the threaded sleeve. A cleaning plate is disposed at the end of the rotating shaft away from the threaded sleeve and abuts against the inner wall of the filter cartridge.

[0014] Furthermore, the pushing component includes several L-shaped plates arranged in a circular array on the inner wall of the filter cartridge. Each L-shaped plate is equipped with a pushing plate and an inclined surface. Several rotating shafts are equipped with movable plates, which are slidably connected to their corresponding pushing plates. Each movable plate is equipped with an insertion rod. Several grooves are arranged in a circular array on the threaded sleeve. The insertion rod is inserted into the inner side of the corresponding groove. A return spring is provided between the insertion rod and the inner wall of the groove.

[0015] Furthermore, the limiting rotation assembly includes a limiting ring disposed on a rotating shaft, two limiting blocks symmetrically distributed on the limiting ring, the limiting ring being fixedly connected to the corresponding moving plate, two limiting grooves symmetrically distributed on the rotating shaft, the two limiting blocks being slidably connected to the inner side of the two limiting grooves respectively, and a circular groove communicating with the limiting grooves on the rotating shaft, the two limiting blocks being slidably connected to the inner side of the circular groove.

[0016] Furthermore, the one-way rotation assembly includes a toothed plate mounted on an L-shaped plate, and a gear mounted on the rotation shaft via a one-way bearing, the gear meshing with the toothed plate.

[0017] Furthermore, the cleaning assembly includes an outer cylinder disposed inside the purification cylinder, a cleaning cotton plate disposed on the outer cylinder, a compression spring disposed between the cleaning cotton plate and the outer cylinder, an internally threaded cylinder disposed on the outer cylinder, an insert sleeve disposed at the bottom of the threaded sleeve, the insert sleeve being inserted into the inner side of the internally threaded cylinder, and a protrusion disposed on the insert sleeve, the protrusion being slidably connected to the internal thread of the internally threaded cylinder.

[0018] Furthermore, it also includes an installation and disassembly assembly located at the bottom of the purification cylinder. The purification cylinder is equipped with a ring plate, and the bottom of the purification cylinder is equipped with a base plate. The outer cylinder is rotatably connected to the base plate, and the base plate and the ring plate are assembled by screws.

[0019] Another object of the present invention is to provide a method for purifying welding fumes used in memory module manufacturing, comprising the following steps:

[0020] S1: Start the main body of the welding equipment to perform memory module welding operation. At the same time, turn on the fan in the air duct. The operation of the fan creates a negative pressure on the symmetrically distributed suction hoods on the main body of the welding equipment, which quickly sucks in the welding fumes. The fumes are collected by the suction hoods to the horizontal pipe, and then introduced into the first vertical pipe from the horizontal pipe, completing the initial collection and transportation of fumes.

[0021] S2: After the smoke and dust enter the first vertical pipe, the evenly distributed conical guide plates inside the pipe guide the smoke and dust to flow slowly, prolonging the residence time of the smoke and dust in the pipe and allowing it to fully contact the inner wall of the first vertical pipe. At the same time, the liquid outlet pipe and liquid inlet pipe of the cooling cylinder are connected to the external coolant circulation system, respectively, to build a circulation foundation for the subsequent cooling of the smoke and dust, and realize the pre-flow of smoke and dust and the preparation for cooling.

[0022] S3: The push ring slides up and down inside the first vertical pipe and the cooling cylinder. When it moves up, the cover plate closes the through hole due to gravity, pushing the heated coolant in the cooling cylinder out of the outlet pipe. At the same time, a negative pressure is formed at the bottom to draw in new coolant. When it moves down, the cover plate opens under water pressure, stirring the coolant so that it evenly coats the first vertical pipe, continuously reducing the temperature of the dust inside the pipe and preventing high-temperature dust from corroding the filter cartridge.

[0023] S4: The cooled fumes enter the second vertical pipe from the first vertical pipe, and then flow into the filter cartridge inside the purification cylinder. The filter cartridge intercepts and filters particulate matter such as metal oxides in the fumes. The filtered clean gas is discharged through the exhaust pipe, completing the purification treatment of welding fumes and ensuring the safety of the surrounding environment and equipment operation.

[0024] The beneficial effects of this invention are:

[0025] The staggered distribution of guide plates extends the residence time of flue gas within the first vertical pipe, ensuring sufficient contact with the cooled pipe wall and initially reducing the flue gas temperature. The reciprocating movement of the driving ring dynamically replaces and agitates the coolant, ensuring continuous and uniform cooling of the first vertical pipe and preventing localized overheating. This significantly slows down the oxidation reaction rate between metal oxides and the filter cartridge substrate, reducing corrosion and extending the filter cartridge's lifespan. Simultaneously, the stable low-temperature environment prevents sealing failure due to thermal expansion and contraction, ensuring filtration accuracy while effectively preventing secondary pollution caused by unfiltered flue gas leakage.

[0026] A reciprocating screw drives the cleaning plate to slide up and down along the inner wall of the filter cartridge, effectively scraping away attached metal particles in real time and preventing the formation of a dense dust cake. Combined with a unidirectional rotation component and a limit rotation component, the cleaning plate can precisely rotate and directionally transport particles, ensuring that impurities are guided to the bottom of the filter cartridge regardless of its vertical movement, thus improving cleaning efficiency. Frequent shutdowns for cleaning are eliminated, increasing the effective utilization of welding process time. Simultaneously, continuous cleaning prevents airflow reduction due to filter cartridge blockage.

[0027] The cleaning assembly ensures the cleaning plate remains in high-efficiency operation for extended periods by providing real-time cleaning. The cleaning pad, held in place by a spring, remains firmly attached to the cleaning plate, while the outer cylinder rotates synchronously with the threaded sleeve, thoroughly removing residual particles from the cleaning plate surface and preventing impurities from accumulating and affecting the scraping effect. Compared to traditional cleaning structures, the cleaning plate improves the scraping rate of the filter cartridge's inner wall after cleaning, effectively preventing filter cartridge clogging caused by secondary particle adhesion. Furthermore, the simplified installation and removal assembly streamlines the maintenance process for the cleaning pad, allowing for cleaning or replacement without disassembling the entire purification cartridge. The reusability of the cleaning pad also avoids frequent consumable replacements, further reducing system operating costs. Attached Figure Description

[0045] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0046] Example 1, referring to Figures 1-7This first embodiment of the invention provides a welding fume purification system for memory module manufacturing, comprising a welding equipment body 1, a plurality of suction hoods 11 symmetrically distributed and fixedly connected to the welding equipment body 1, a horizontal pipe 12 fixedly connected to the air outlet ends of the plurality of suction hoods 11, a first vertical pipe 13 fixedly connected to the bottom of the horizontal pipe 12, a second vertical pipe 14 rotatably connected to the bottom of the first vertical pipe 13, a purification cylinder 15 rotatably connected to the bottom of the second vertical pipe 14, a filter cylinder 16 fixedly connected to the inner side of the purification cylinder 15, and two air outlet pipes 17 symmetrically distributed and fixedly connected to the purification cylinder 15, each air outlet pipe 17 having a fan 18 fixedly connected to its inner side. The system also includes a cooling and cleaning unit installed on the welding equipment body 1; the cooling and cleaning unit includes a cooling component installed on the first vertical pipe 13 and a cleaning component installed on the welding equipment body 1, the cooling component including a cooling assembly 2 installed on the first vertical pipe 13. The second vertical pipe 14 is equipped with a drive assembly 3 and a rotating assembly 4; the cooling component is used to cool the welding fumes entering the first vertical pipe 13, and the cleaning component is used to clean the particles on the inner wall of the filter cartridge 16; the cooling assembly 2 includes a cooling cylinder 21 fixedly connected to the first vertical pipe 13, a liquid outlet pipe fixedly connected to one side of the top of the cooling cylinder 21, a liquid inlet pipe fixedly connected to one side of the bottom of the cooling cylinder 21, a push ring 22 is also sealed and slidably connected to the first vertical pipe 13, the push ring 22 is sealed and slidably connected to the inner side of the cooling cylinder 21, a number of through holes 23 are distributed in a ring array on the push ring 22, a cover plate 24 is rotatably connected to the top of the through holes 23 on the push ring 22, a baffle ring is provided at the bottom of the inner side of the first vertical pipe 13, a number of conical guide plates 25 are evenly distributed on the top of the baffle ring, arc-shaped openings are staggered on the number of conical guide plates 25, and the number of conical guide plates 25 are fixedly connected to each other.

[0047] Specifically, the memory module to be processed is welded by the main body 1 of the welding equipment. The fan 18 is started, so that several suction hoods 11 have suction force. The fumes generated during the welding process are absorbed by the suction hoods 11. The fumes pass through the horizontal pipe 12, enter the first vertical pipe 13 and the second vertical pipe 14, pass through the purification cylinder 15, and enter the filter cylinder 16 to filter the fumes. The filtered fumes will be discharged from the air outlet 17, completing the purification treatment of the fumes. The outlet pipe is connected to the inlet of the external coolant, and the inlet pipe is connected to the outlet of the coolant. When the dust enters the first vertical pipe 13, it flows slowly within the first vertical pipe 13 due to the action of several conical guide plates 25 and the arc-shaped openings on the conical guide plates 25, and contacts the inner wall of the first vertical pipe 13 as much as possible. When the horizontal pipe 12 is disassembled from the first vertical pipe 13, the multiple conical guide plates 25 fixed together can be pulled out from the first vertical pipe 13 to prevent particles from adhering to the conical guide plates 25 and clogging the first vertical pipe 13. The pushing ring 22 slides on the first vertical pipe 13. As the pushing ring 22 slides upward inside the cooling cylinder 21 and the first vertical pipe 13, and the cover plate 24 is initially closed on the top of the through hole 23 under the action of gravity, sealing the through hole 23, the pushing ring 22 pushes the gas at the top of the cooling cylinder 21 out of the liquid outlet pipe when it slides upward inside the cooling cylinder 21. A negative pressure is formed at the bottom of the cooling cylinder 21, which draws external coolant into the cooling cylinder 21 from the liquid inlet pipe. This causes the temperature at the connection between the cooling cylinder 21 and the first vertical pipe 13 to drop, thus cooling the first vertical pipe 13 and reducing the temperature of the gas passing through the first vertical pipe 13, thereby cooling the smoke and dust. When the pushing ring 22 slides downward inside the cooling cylinder 21, the cover plate 24 rotates upward under the pressure of the water, opening the through hole 23. This prevents the pushing ring 22 from squeezing the cooling water inside the cooling cylinder 21 while it slides, but it does stir the cooling water, making the cooling water more evenly cool the first vertical pipe 13. When the pushing ring 22 moves upward again inside the cooling cylinder 21, under the pressure of the water and the weight of the cover plate 24 itself... The cover plate 24 is then re-sealed on top of the through hole 23, sealing it. As the pushing ring 22 moves upward, it pushes out the cooling liquid that has begun to heat up inside the cooling cylinder 21 from the outlet pipe and draws in the cooler liquid from the outside from the inlet pipe. As the pushing ring 22 moves up and down inside the cooling cylinder 21, it continuously draws in coolant and stirs the coolant, thereby continuously cooling the first vertical pipe 13 and reducing the temperature of the dust passing through it. This lowers the temperature of the dust entering the filter cartridge 16, preventing the large amount of metal oxides in the dust from adhering to the inner wall of the filter cartridge 16 and causing corrosion and oxidation.

[0048] Reference Figure 4The drive assembly 3 includes a reciprocating spiral groove formed on the second vertical tube 14. The second vertical tube 14 is also threaded with a nut 31. Two drive rods 32 are fixedly connected to the nut 31 in a symmetrical arrangement. The top of the drive rods 32 passes through the cooling cylinder 21 and is fixedly connected to the push ring 22.

[0049] Specifically, when the second vertical tube 14 rotates, since there are reciprocating spiral grooves distributed on the outer side of the second vertical tube 14, the nut 31 is threadedly connected to the second vertical tube 14. Under the action of the drive rod 32, the nut 31 slides back and forth on the outer side of the second vertical tube 14, and through the drive rod 32, drives the push ring 22 to move back and forth.

[0050] Reference Figure 7 The rotating assembly 4 includes a rotating shaft 41 rotatably connected to the inner side of the purification cylinder 15, a turbine blade 42 fixedly sleeved on the rotating shaft 41, a rotating plate 43 fixedly connected to the top of the rotating shaft 41, and the rotating plate 43 fixedly connected to the inner wall of the second vertical pipe 14.

[0051] Specifically, when the smoke and dust pass through the inside of the second vertical pipe 14, the flow of the smoke and dust causes the turbine blades 42 to rotate, which in turn drives the rotating plate 43 to rotate via the rotating shaft 41, thereby driving the second vertical pipe 14 to rotate.

[0052] Example 2, refer to Figures 8-14 This is the second embodiment of the present invention, which differs from the first embodiment in that: the cleaning component includes a cleaning assembly 5 installed inside the filter cartridge 16, a pushing assembly 6 installed on the cleaning assembly 5, a limiting rotation assembly 7 installed between the cleaning assembly 5 and the pushing assembly 6, a one-way rotation assembly 8 installed on the cleaning assembly 5, and a cleaning assembly 9 installed at the bottom of the filter cartridge 16; the cleaning assembly 5 includes a reciprocating screw 51 rotatably connected to the inside of the filter cartridge 16, the top of the reciprocating screw 51 being fixedly connected to the rotating shaft 41, two smooth rods 52 symmetrically distributed inside the filter cartridge 16, the two smooth rods 52 being fixedly connected to the purification cartridge 15, a threaded sleeve 53 threadedly connected to the outside of the reciprocating screw 51, the threaded sleeve 53 being slidably connected to the two smooth rods 52 respectively, a plurality of rotating shafts 54 rotatably connected to the threaded sleeve 53 in a ring array, a cleaning plate 55 being fixedly connected to the end of the rotating shaft 54 ​​away from the threaded sleeve 53, and the cleaning plate 55 abutting against the inner wall of the filter cartridge 16.

[0053] Specifically, when the rotating shaft 41 rotates, it drives the reciprocating screw 51 to rotate. Under the action of the two guide rods 52, the threaded sleeve 53 slides up and down on the outside of the reciprocating screw 51, driving the rotating shaft 54 ​​to move. This causes the cleaning plate 55 to slide up and down on the inner wall of the filter cartridge 16, cleaning the inner wall of the filter cartridge 16. When the cleaning plate 55 slides down, it scrapes off the particles on the inner wall of the filter cartridge 16. When the cleaning plate 55 slides up, it scrapes the particles on the filter cartridge 16 upwards. When the cleaning plate 55 moves to the top of the filter cartridge 16, the rotating shaft 54 ​​rotates 180 degrees, causing the cleaning plate 55 to rotate 180 degrees, so that the particles scraped off the cleaning plate 55 face down. When the cleaning plate 55 slides down, it drags the scraped particles down with it. Regardless of whether the cleaning plate 55 slides up or down, it eventually scrapes the particles on the filter cartridge 16 to the bottom of the filter cartridge 16.

[0054] Reference Figure 10 and Figure 11 The pushing component 6 includes several L-shaped plates 61 arranged in a ring array and fixedly connected to the inner wall of the filter cartridge 16. A pushing plate 62 is fixedly connected to the L-shaped plate 61. The pushing plate 62 has an inclined surface. Several rotating shafts 54 are slidably connected to moving plates 63. The moving plates 63 are slidably connected to the corresponding pushing plates 62. A plug rod 64 is fixedly connected to the moving plate 63. Several grooves are arranged in a ring array on the threaded sleeve 53. The plug rod 64 is inserted into the inner side of the corresponding groove. A return spring 65 is fixedly connected between the plug rod 64 and the inner wall of the groove.

[0055] Specifically, when the threaded sleeve 53 slides upward, it causes the moving plate 63 to move closer to the pushing plate 62. When the moving plate 63 contacts the pushing plate 62, the inclined plane causes the pushing plate 62 to push the moving plate 63 and slide between them, allowing the moving plate 63 to slide on the rotating shaft 54. This causes the insertion rod 64 to slide outward from the groove, stretching the return spring 65. When the threaded sleeve 53 slides downward away from the L-shaped plate 61, the pushing plate 62 gradually moves away from the moving plate 63. Under the reset action of the return spring 65, the moving plate 63 slides closer to the threaded sleeve 53, causing the insertion rod 64 to slide inward from the groove.

[0056] Reference Figures 11-13 The limiting rotation assembly 7 includes a limiting ring 71 slidably connected to the rotating shaft 54. Two limiting blocks 72 are fixedly connected to the limiting ring 71 in a symmetrical manner. The limiting ring 71 is fixedly connected to the corresponding moving plate 63. Two limiting grooves 73 are symmetrically distributed on the rotating shaft 54. The two limiting blocks 72 are slidably connected to the inner side of the two limiting grooves 73 respectively. The rotating shaft 54 ​​is also provided with a circular groove 74 communicating with the limiting grooves 73. Both limiting blocks 72 are slidably connected to the inner side of the circular groove 74.

[0057] Specifically, when the moving plate 63 moves toward the cleaning plate 55, it causes the limiting ring 71 to slide on the rotating shaft 54, causing the limiting block 72 to slide inside the limiting groove 73. At this time, the insertion rod 64 slides inside the groove. Under the action of the groove, the insertion rod 64 is limited, preventing the moving plate 63 from rotating, and consequently preventing the limiting ring 71 from rotating. Under the action of the limiting block 72, the rotating shaft 54 ​​is limited. When the limiting block 72 slides from the inside of the limiting groove 73 into the circular groove 74... When the inner side is in motion, the limiting block 72 slides inside the circular groove 74 under the action of the circular groove 74. At this time, the rotating shaft 54 ​​can rotate. When the moving plate 63 moves towards the threaded sleeve 53, the limiting block 72 slides back into the limiting groove 73 from the inner side of the circular groove 74. Under the action of the return spring 65, the insertion rod 64 is re-inserted into the inner side of the groove, limiting the moving plate 63 and the limiting ring 71. Under the action of the limiting block 72 and the limiting groove 73, the rotating shaft 54 ​​is limited.

[0058] Reference Figure 10 and Figure 11 The one-way rotation assembly 8 includes a toothed plate 81 fixedly connected to an L-shaped plate 61, and a gear 82 fixedly mounted on a rotating shaft 54 ​​via a one-way bearing, the gear 82 meshing with the toothed plate 81.

[0059] Specifically, when the cleaning plate 55 moves upward, the pushing plate 62 first contacts the moving plate 63, pushing the moving plate 63 away from the threaded sleeve 53. This causes the limiting block 72 to slide from the limiting groove 73 into the inner side of the circular groove 74. At this time, the rotating shaft 54 ​​can rotate, and the toothed plate 81 contacts the gear 82, driving the gear 82 to rotate. Through the rotating shaft 54, the cleaning plate 55 rotates 180 degrees, so that when the cleaning plate 55 moves upward, the side with particles faces downward. When the cleaning plate 55 moves downward, the gear 82 moves downward on the toothed plate 81. Under the action of the one-way bearing, the rotating shaft 54 ​​does not rotate at this time. The pushing plate 62 moves away from the moving plate 63. Under the action of the return spring 65, the limiting block 72 slides back into the limiting groove 73 from the inner side of the circular groove 74, limiting the rotating shaft 54 ​​and preventing it from rotating arbitrarily, thus ensuring the stability of the cleaning plate 55 when cleaning particles. The remaining structure is the same as that in Embodiment 1.

[0060] Example 3, referring to Figure 15 This is the third embodiment of the present invention. This embodiment differs from the second embodiment in that: the cleaning component 9 includes an outer cylinder 91 rotatably connected to the inner side of the purification cylinder 15, a cleaning cotton plate 92 slidably connected to the upper limit of the outer cylinder 91, a compression spring 93 fixedly connected between the cleaning cotton plate 92 and the outer cylinder 91, an internally threaded cylinder 94 fixedly connected to the outer cylinder 91, an insert 95 fixedly connected to the bottom of the threaded sleeve 53, the insert 95 being inserted into the inner side of the internally threaded cylinder 94, a protrusion 96 fixedly connected to the insert 95, and the protrusion 96 being slidably connected to the internal thread of the internally threaded cylinder 94.

[0061] Specifically, when the cleaning plate 55 moves downward, it drives the insert 95 downward, causing the insert 95 to engage with the inner side of the internally threaded cylinder 94. Under the action of the protrusion 96 and the internal thread, the outer cylinder 91 rotates. Due to the limited sliding connection between the outer cylinder 91 and the cleaning cotton plate 92, the cleaning cotton plate 92 rotates. At this time, the cleaning plate 55 just contacts the cleaning cotton plate 92. When the cleaning cotton plate 92 rotates, it cleans the particles removed from the cleaning plate 55, ensuring that the cleaning plate 55 is clean when cleaning the particles on the inner wall of the filter cartridge 16, and preventing particles from accumulating on the cleaning plate. On plate 55, the cleaning plate 55 continuously moves downward, and the cleaning plate 55 comes into contact with the cleaning cotton plate 92, squeezing the cleaning cotton plate 92 downward and compressing the clamping spring 93. Under the action of the clamping spring 93, the cleaning cotton plate 92 is always in contact with the cleaning plate 55, ensuring the continuous cleaning of the cleaning plate 55. When the cleaning plate 55 moves upward, the insert 95 moves out from the inside of the internal threaded cylinder 94. Under the action of the protrusion 96 and the internal thread, the outer cylinder 91 rotates in the opposite direction, driving the cleaning cotton plate 92 to rotate in the opposite direction, performing reverse cleaning on the cleaning plate 55, and cleaning the cleaning plate 55 more thoroughly.

[0062] Reference Figure 3 , Figure 8 and Figure 9 It also includes an installation and disassembly assembly 10 installed at the bottom of the purification cylinder 15. A ring plate 101 is fixedly connected to the purification cylinder 15. A bottom plate 102 is provided at the bottom of the purification cylinder 15. The outer cylinder 91 is rotatably connected to the bottom plate 102. The bottom plate 102 and the ring plate 101 are assembled by screws.

[0063] Specifically, tighten the screws to fix the base plate 102 and the ring plate 101, install the installation and disassembly assembly 10, loosen the screws to disassemble the base plate 102 and the ring plate 101, and remove the outer cylinder 91 from the purification cylinder 15 to facilitate cleaning of the cleaning cotton plate 92. This ensures that the cleaning cotton plate 92 does not have a large amount of particulate matter adhering to it when cleaning the cleaning plate 55, which would result in incomplete cleaning of the cleaning plate 55. The remaining structure is the same as that in Embodiment 2.

[0064] Based on embodiments 1-3, the working principle of the present invention is as follows: When the main body 1 of the welding equipment is in operation, the fan 18 in the exhaust duct 17 is started, which generates negative pressure in the symmetrically distributed suction hoods 11, drawing in the welding fumes and collecting them through the horizontal pipe 12 to the first vertical pipe 13. When the fumes flow through the first vertical pipe 13, the external coolant enters the cooling cylinder 21 through the inlet pipe. The staggered conical guide plates 25 slow down the flow rate of the fumes, allowing them to fully contact the inner wall of the cooled first vertical pipe 13, achieving initial cooling. At the same time, the second vertical pipe 14 rotates, causing the nut 31 to slide along the reciprocating spiral groove, and the drive rod 32 pulls the ring 22 to move up and down inside the cooling cylinder 21. When moving upward, the cover plate 24 closes the through hole 23, pushing out the heated coolant and drawing in new coolant. When moving downward, the cover plate 24 opens to stir the coolant, ensuring continuous and uniform cooling and preventing high-temperature fumes from corroding the filter cartridge 16. After being cooled, the smoke and dust enter the second vertical pipe 14. The flowing smoke and dust drive the turbine blades 42 to rotate, which in turn drives the rotating plate 43 to rotate synchronously with the second vertical pipe 14 via the rotating shaft 41, providing power for the subsequent cleaning components. The smoke and dust then enter the filter cartridge 16 inside the purification cylinder 15, where it is filtered and discharged from the outlet pipe 17. The rotating shaft 41 drives the reciprocating screw 51 to rotate, and the threaded sleeve 53 slides up and down along the smooth rod 52, causing the cleaning plate 55 to adhere to the inner wall of the filter cartridge 16 and scrape off the particles. When the threaded sleeve 53 moves upward, the moving plate 63 slides under the action of the inclined surface of the pushing plate 62, and the limiting block 72 slides into the circular groove 74 to release the restriction on the rotating shaft 54. The toothed plate 81 drives the gear 82 to rotate the cleaning plate 55 180°, ensuring that the particles face the bottom of the filter cartridge 16. When moving downward, the reset spring 65 pulls the insertion rod 64 to reset, and the limiting block 72 re-limits the rotating shaft 54, ensuring cleaning stability. Simultaneously, as the threaded sleeve 53 moves downward, the insert 95 drives the outer cylinder 91 to rotate, and the cleaning cotton plate 92 adheres to the cleaning plate 55 under the action of the compression spring 93, removing residual particles from its surface. The installation and removal assembly 10 at the bottom of the purification cylinder 15 allows for convenient cleaning of the cleaning cotton plate 92 by removing the base plate 102, ensuring continuous operation of the system.

[0065] Example 4, refer to Figures 1-15 The fourth embodiment of the present invention provides a method for purifying welding fumes used in memory module manufacturing, comprising the following steps:

[0066] S1: Start the main body 1 of the welding equipment to perform memory module welding operation. At the same time, turn on the fan 18 in the air outlet duct 17. The operation of the fan 18 creates a negative pressure on the symmetrically distributed suction hoods 11 on the main body 1 of the welding equipment, which quickly sucks in the welding fumes. The fumes are collected by the suction hoods 11 and then introduced into the first vertical pipe 13 through the horizontal pipe 12, completing the initial collection and transportation of fumes.

[0067] S2: After the smoke and dust enter the first vertical pipe 13, the evenly distributed conical guide plates 25 inside the pipe guide the smoke and dust to flow slowly, prolonging the residence time of the smoke and dust in the pipe, so that it can fully contact the inner wall of the first vertical pipe 13. At the same time, the liquid outlet pipe and liquid inlet pipe of the cooling cylinder 21 are connected to the external coolant circulation system, respectively, to build a circulation foundation for the subsequent cooling of the smoke and dust, and realize the pre-flow of smoke and dust and the preparation for cooling.

[0068] S3: The push ring 22 slides up and down inside the first vertical pipe 13 and the cooling cylinder 21. When it moves up, the cover plate 24 closes the through hole 23 due to gravity, pushing the heated coolant in the cooling cylinder 21 out of the outlet pipe. At the same time, a negative pressure is formed at the bottom to draw in new coolant. When it moves down, the cover plate 24 opens under water pressure, stirring the coolant so that it evenly coats the first vertical pipe 13, continuously reducing the temperature of the dust inside the pipe, and preventing high-temperature dust from corroding the filter cartridge 16.

[0069] S4: The cooled fumes enter the second vertical pipe 14 from the first vertical pipe 13, and then flow into the filter cartridge 16 in the purification cylinder 15. The filter cartridge 16 intercepts and filters particulate matter such as metal oxides in the fumes. The filtered clean gas is discharged through the air outlet pipe 17, completing the purification treatment of welding fumes and ensuring the safety of the surrounding environment and equipment operation.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
