Description

Technical Field

[0001] This invention relates to the field of air purification technology, and in particular to a fume purification device for soldering. Background Technology

[0002] When soldering, the flux in the solder wire comes into contact with the high-temperature soldering iron and vaporizes to form fumes. These fumes contain harmful particles that are harmful to the human body, so it is necessary to use fume purification equipment to absorb the fumes during soldering. Existing technologies typically involve smoke passing through a filter cartridge, where harmful particles are intercepted and removed. However, because the smoke passes through the filter cartridge in a constant direction, harmful particles tend to accumulate on the outer or inner sides of the cartridge, concentrating in the same location. This results in inadequate filtration of smoke in different parts of the filter cartridge, hindering the rapid removal of harmful particles from various locations. Therefore, there is an urgent need for a smoke purification device for soldering. Summary of the Invention

Detailed Implementation

[0017] Example 1: Reference Figures 1 to 6 A fume purification device for soldering includes: a filter box 1, with a detachable disassembly plate 15 detachably mounted on the side of the filter box 1; a fixing plate 2, fixedly mounted on the inner wall of the filter box 1; a power component 12, fixedly mounted on the side of the filter box 1 via a support rod, the power component 12 being an AC motor that can be purchased from the market or custom-made, and capable of driving a rotating rod 3 to rotate at high speed when current is applied to the power component 12; a vertical pipe 13, fixedly mounted through the top of the filter box 1; a horizontal pipe 14, fixedly mounted through the front of the filter box 1, the vertical pipe 13 and the horizontal pipe 14 being perpendicular; a rotating rod 3, one end of which is fixedly mounted on the power output end of the power component 12; a fluid drive mechanism, fixedly mounted on the rotating rod 3 and located inside the filter box 1, the fluid drive mechanism causing airflow through high-speed rotation of impeller blades 32; and a filtration mechanism, detachably mounted inside the filter box 1, capable of filtering fume.

[0018] In this invention, the filtration mechanism includes: two support plates 4, which are detachably disposed inside the filter box 1; and two separator cylinders 41, which are fixedly disposed between the two support plates 4, each separator cylinder 41 having multiple round holes in its opening, as shown in the appendix to the specification. Figure 4As shown; filter cartridge 42, the filter cartridge 42 is filled in the annular space formed by two partition cartridges 41 and two support plates 4. The filter cartridge 42 is made of steel wire and fiber filaments interwoven together. The steel wire accounts for 10% to 15% of the filter cartridge 42, and the fiber filaments are PP fiber filaments or glass fiber filaments. The filter cartridge 42 can filter harmful particles in smoke.

[0019] In this invention, the fluid drive mechanism includes: a support frame 21, multiple support frames 21 are fixedly installed on the inner wall of the filter box 1, the side of the support frame 21 abuts against the side of the support plate 4, which can limit the position of the support plate 4; two return cylinders 23 are rotatably installed inside the filter box 1 by a rotating component, which is a support component 16, which passes through the side of the filter box 1 and through the end of the return cylinder 23. The support component 16 is sleeved on the rotating rod 3, and the support component 16 is a sealed bearing that can be obtained by purchasing from the market or by private customization, so that the two return cylinders 23 can be rotatably sleeved on both ends of the rotating rod 3. The support component 16 is movably inserted through the middle of the disassembly plate 15, so that the rotating rod 3 can be rotatably inserted through the middle of the disassembly plate 15.

[0020] In this invention, two partition plates 24 are fixedly sleeved on the ends of two return cylinders 23, and the outer diameter of the partition plate 24 is smaller than the inner diameter of the support plate 24, so that the filter cylinder 42 can be installed on the periphery of the intermediate plate 35; the two ends of the return pipe 25 are fixedly set in the middle of one of the return cylinders 23 and the end of the vertical pipe 13, and the interiors of the vertical pipe 13, the return pipe 25, and the vertical pipe 13 are interconnected; one end of the threaded pipe 26 is fixedly set in the middle of the other return cylinder 23, and the interiors of the threaded pipe 26 and the return cylinder 23 are interconnected.

[0021] In this invention, the fluid drive mechanism further includes: a threaded cylinder 27, which is threadedly sleeved to the other end of the threaded pipe 26. The threaded cylinder 27 rotates and moves along the axial direction of the threaded pipe 26. The end of the threaded cylinder 27 can be threadedly sleeved to the end of the elbow pipe 29, so that the interiors of the threaded pipe 26 and the elbow pipe 29 are interconnected, and the smoke can flow sequentially inside the threaded pipe 26, the threaded cylinder 27, and the elbow pipe 29; an elbow pipe 29, which is fixedly disposed at the end of the vertical pipe 13, and the interiors of the vertical pipe 13 and the elbow pipe 29 are interconnected; and a limiting ring 28, which is fixedly sleeved to one end of the elbow pipe 29. The limiting ring 28 can limit the threaded cylinder 27, so that the two ends of the threaded cylinder 27 are respectively threadedly sleeved to the ends of the threaded pipe 26 and the elbow pipe 29.

[0022] In this invention, the fluid drive mechanism further includes: closed plates 31, two closed plates 31 are fixedly sleeved on the rotating rod 3, and the outer diameter of the closed plates 31 and the outer diameter of the closed ring 33 are consistent; impeller blades 32, multiple impeller blades 32 are respectively fixedly disposed on the sides of the two closed plates 31, and the impeller blades 32 rotate at high speed to fling smoke; closed rings 33, two closed rings 33 are respectively fixedly disposed on the edges of the multiple impeller blades 32, the two closed rings 33 are located in the middle of the multiple surrounding rods 39, and the middle of the closed rings 33 does not contact the rotating rod 3 to form an annular air intake space.

[0023] In this invention, an intermediate plate 35 is rotatably mounted on a rotating rod 3 via a rotating component, which is a second support 34. The second support 34 is mounted on the rotating rod 3 and passes through the middle of the intermediate plate 35. The second support 34 is a ball bearing, which can be obtained through market purchase or private customization, allowing the intermediate plate 35 to be rotatably mounted on the rotating rod 3. A corner ring 36 is fixedly mounted on the edge of the intermediate plate 35 and is located between two closed plates 31 to prevent smoke from entering the gap between the two closed plates 31. Multiple pins 37 are fixedly mounted through the corner ring 36. The pins 37 are triangular in shape, which can reduce the resistance generated by the pins 37 during the flow of smoke.

[0024] In this invention, the impeller blades 32 are divided into two parts of different lengths. The two impeller blades 32 of different lengths are arranged around the gap between the closed plate 31 and the closed ring 33. The two closed plates 31 are located in the middle of the two closed rings 33. When the two sets of closed plates 31, impeller blades 32 and closed rings 33 rotate synchronously, the smoke is drawn in through the middle of the two closed rings 33. The smoke is drawn in from both ends of the filter cylinder 42. The smoke is thrown away by the high-speed rotating impeller blades 32, generating a huge centrifugal force, so that the smoke passes through the filter cylinder 42 from the inside to the outside. The direction of the smoke passing through the filter cylinder 42 is opposite to that in Embodiment 2. The intermediate plate 35 is located in the middle of the two closed plates 31. The two ends of the multiple pins 37 are respectively fixed on the sides of the two partition plates 24. The multiple pins 37 are arranged around the periphery of the two closed rings 33 and around the inner side of the filter cylinder 42. The other end of the threaded cylinder 27 can be threaded onto one end of the elbow pipe 29.

[0025] In use, firstly, the vertical pipe 13 is fitted onto the smoke absorption pipe. The power unit 12 is connected to the power supply, and the rotating rod 3 of the power unit 12 rotates at high speed, causing the rotating rod 3, the partition plate 24, the closed plate 31, the impeller blades 32, and the closed ring 33 to rotate synchronously at high speed. The two sets of impeller blades 32 rotate at high speed and swing the smoke, causing the smoke to be continuously drawn into the two return cylinders 23 through the middle of the closed ring 33. The smoke is quickly drawn into the closed ring 33, causing the smoke to flow sequentially inside the absorption pipe, the vertical pipe 13, the return pipe 25, and the return cylinder 23. The smoke is rapidly flowing through the absorption pipe, the vertical pipe 13, the return pipe 25, and the return cylinder 23. The smoke is drawn in by one of the closed coils 33, while another part of the smoke flows sequentially inside the absorption pipe, vertical pipe 13, elbow pipe 29, threaded cylinder 27, threaded pipe 26 and return cylinder 23. The smoke is quickly drawn in by another closed coil 33. The two sets of impeller blades 32 rotate at high speed and swing the smoke. The smoke passes through the separator cylinder 41 and the filter cylinder 42. The filter cylinder 42 filters the smoke. The smoke enters the horizontal pipe 14 and is discharged from the inside of the filter box 1 through the horizontal pipe 14. The smoke passes through the filter cylinder 42 from the inside to the outside for filtration, completing the smoke filtration work. When replacing the filter cartridge 42, remove the disassembly plate 15 from the side of the filter box 1 by hand, then rotate the threaded cylinder 27 by hand. The threaded cylinder 27 moves downward along the axial direction of the threaded tube 26. Then move the support plate 4, the partition cylinder 41, and the filter cartridge 42 along the axial direction of the rotating rod 3. The support plate 4, the partition cylinder 41, and the filter cartridge 42 can be removed from the inside of the filter box 1. Then put the new support plate 4, the partition cylinder 41, and the filter cartridge 42 on the two partition plates 24. The support plate 4 rests against the side of the support frame 21 to complete the replacement of the filter cartridge 42.

[0026] Example 2: Reference Figures 7 to 12 The difference from Embodiment 1 is that the fluid drive mechanism includes: a magnet frame 17, which is fixedly disposed on the side of the disassembly plate 15. The disassembly plate 15 is inserted into the side of the filter box 1, so that the magnet frame 17 is close to the alloy frame 18. The magnet frame 17 is attracted to the side of the alloy frame 18, so that the disassembly plate 15 can be detachably installed on the side of the filter box 1; an alloy frame 18, which is fixedly sleeved on the side of the filter box 1; and a fixing frame 311, a plurality of fixing frames 311 are fixedly disposed on the inner wall of the filter box 1. 311 One of the fixed ring plates 310 is fixed to the inner wall of the filter box 1; side ring cylinder 38, one of the side ring cylinders 38 is fixedly set on the fixing frame 311, the side ring cylinder 38 can collect the smoke thrown out by the two sets of impeller blades 32; surround rod 39, the two ends of multiple surround rods 39 are respectively fixedly set on the inclined surface of the two side ring cylinders 38, the surround rod 39 fixes the two side ring cylinders 38 together, so that the two side ring cylinders 38, the two fixed ring plates 310, the multiple fixing frames 311 and other structures are fixed to the inner wall of the filter box 1.

[0027] In this invention, the fluid drive mechanism further includes: fixed ring plates 310, two fixed ring plates 310 being rotatably mounted on a rotating rod 3 via a rotating member, the rotating member being a support member 34, two support members 34 being mounted on the rotating rod 3, the two support members 34 respectively passing through the middle of the two fixed ring plates 310, so that the two fixed ring plates 310 are rotatably mounted on the rotating rod 3; a corner pipe 312, the two ends of the corner pipe 312 being fixedly disposed at the middle of one of the side ring cylinders 38 and the end of the vertical pipe 13, the interiors of the side ring cylinder 38, the corner pipe 312 and the vertical pipe 13 being interconnected; a connecting pipe 313, the connecting pipe 313 being fixedly disposed on the side of the disassembly plate 15 via a support rod, the interiors of the side ring cylinder 38, the connecting pipe 313 and the vertical pipe 13 being interconnected; and a docking cylinder 314, the docking cylinder 314 being fixedly disposed at the end of the vertical pipe 13.

[0028] In this invention, the connecting cylinder 314 is movably sleeved on the end of the connecting pipe 313, and the two closed rings 33 are located between the two closed plates 31. When the two sets of closed plates 31, impeller blades 32, and closed rings 33 rotate synchronously, smoke is drawn in through the gap between the two closed rings 33. The smoke is drawn in at high speed through the gap between the two closed rings 33, and is thrown into the side ring cylinder 38 by the high-speed rotating impeller blades 32, so that the smoke passes through the filter cylinder 42 from the outside to the inside. The direction of the smoke passing through the filter cylinder 42 is opposite to that in Embodiment 1. The filter cylinder 42 in Embodiment 1 can be replaced for use in Embodiment 2. In Embodiment 1, the smoke passes through the filter cylinder 42 from the outside to the inside. During this process, harmful particles in the smoke accumulate on the outside of the filter cylinder 42. When the filter cartridge 42 is replaced for use in Embodiment 2, firstly, clean smoke passes through the filter cartridge 42 from the inside out. The smoke carries away harmful particles from the outside of the filter cartridge 42, thus cleaning the filter cartridge 42. Then, smoke can be inhaled, and the harmful particles in the smoke will accumulate on the inside of the filter cartridge 42. The filter cartridge 42 is used in both Embodiment 1 and Embodiment 2, continuously cleaning the harmful particles on the outside and inside of the filter cartridge 42. Both the outside and inside of the filter cartridge 42 can filter smoke, and the filter cartridge 42 can fully filter pressure. Both the outside and inside of the filter cartridge 42 can be fully utilized. The filter cartridge 42 is cleaned after replacement, which greatly increases the filtration effect and service life of the filter cartridge 42.

[0029] In this invention, the middle opening of the side ring cylinder 38 is provided with a mating interface. The mating interfaces of the two side ring cylinders 38 are respectively connected to the ends of the corner tube 312 and the mating tube 313. The two side ring cylinders 38 are sleeved on both ends of the rotating rod 3. The alloy frame 18 is made of nickel alloy or iron alloy magnetic material. The magnet frame 17 is sleeved on the side of the filter box 1. The corner tube 312 is fixedly installed on the side of the fixed plate 2. The two side ring cylinders 38 are respectively fixedly installed on the edges of the two fixed ring plates 310. The two support plates 4 are respectively movably sleeved on the periphery of the two side ring cylinders 38.

[0030] In use, firstly, the horizontal pipe 14 is fitted with the absorption pipe, the power component 12 is connected to the power supply, and the rotating rod 3 of the power component 12 rotates at high speed, causing the rotating rod 3, the closed plate 31, the impeller blade 32 and the closed ring 33 to rotate at high speed synchronously. The smoke is thrown into the interior of the two side ring cylinders 38 by the impeller blade 32. The smoke is quickly drawn in through the gap between the two closed rings 33. The smoke passes through the filter cylinder 42 from the outside to the inside. Harmful particles in the smoke accumulate on the outside of the filter cylinder 42. During this process, the smoke is drawn into the interior of the filter box 1 through the horizontal pipe 14 and the absorption pipe. The smoke inside the two side ring cylinders 38 enters the corner pipe 312 and the connecting pipe 313 respectively. The smoke then enters the vertical pipe 13. The smoke inside the filter box 1 is discharged through the vertical pipe 13, completing the smoke filtration work. When replacing the filter cartridge 42, use your hand to hold the disassembly plate 15 and remove it from the side of the filter box 1. Separate the magnet frame 17 from the alloy frame 18. Remove the connecting pipe 313, disassembly plate 15, and alloy frame 18 from the inside of the filter box 1. Then remove the support plate 4, the partition cylinder 41, and the filter cartridge 42 from the side ring cylinder 38. After replacing the filter cartridge 42 in Embodiment 1, the replacement of the filter cartridge 42 is completed. The filter cartridge 42 can be used in Embodiment 1 and Embodiment 2.

[0031] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
