[0030] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0031] As Figures 1 to 4 shown, the present utility model discloses a multi-point spot welding fume collection device, including a welding fume treatment box 1, a collection pipe 2 and a clamping device 3. The welding fume treatment box 1 is in a box shape. The welding fume treatment box 1 is used for centrally treating the collected fumes, and the welding fume treatment box 1 is used to define a welding fume treatment chamber 11. A liquid 12 is disposed in the welding fume treatment chamber 11. The liquid 12 can be used to adsorb and purify the welding fumes, which can reduce the floating of the fumes in the welding fumes in the air, avoid polluting the air, and at the same time the liquid 12 can effectively adsorb the particulate impurities in the welding fumes to achieve a purification effect. For example, the liquid 12 is rosin water. During the welding process, rosin water can, through its characteristics, effectively adsorb the soot particles generated by welding, playing a role in purifying the welding environment. Although the smell of rosin water is not strong, long-term use will cause harm to the human body. Another example is that the liquid is water. Water is colorless and odorless, can effectively adsorb particulate impurities, and can also reduce the floating of the fumes, thereby effectively wet-filtering the welding fumes, and then enhancing the adsorption force and purification force.

[0032] Continue to refer to Figures 1 to 3, multiple collection pipes 2 are installed on the welding fume treatment box 1. The first end 21 of each collection pipe 2 extends into the welding fume treatment chamber 11, and the second end 22 of each collection pipe 2 is placed outside the welding fume treatment box 1. The second end 22 has a horn-shaped structure. The collection pipe 2 with a horn-shaped structure can expand the collection range of welding fumes, thereby improving work efficiency. The collection pipe 2 is in communication with the inside of the welding fume treatment chamber 11, so that it is convenient for welding fumes to enter the welding fume treatment chamber 11 through the collection pipe 2 for centralized treatment. The pipe body of each collection pipe 2 is a flexible pipe. In one example, the collection pipe 2 is a polyethylene hose, which has good flexibility, anti-aging property and high temperature resistance. During the welding process, the collection pipe 2 can be flexibly moved to the position of the required welding operation area, so as to effectively collect welding fumes and ensure that the sparks generated during welding will not affect the performance of the collection pipe 2, so as to ensure the normal operation of the collection work. Among them, a clamping device 3 is provided at the second end 22 of the collection pipe 2. The clamping device 3 is used to fix and support the collection pipe 2. The clamping device 3 can clamp the collection pipe 2 and adjust its position according to the required height and position to ensure the stability of the collection pipe 2.

[0033] In some embodiments, such as Figure 1 shown, the clamping device 3 includes a support rod 31 and a clamp 32. The support rod 31 is a metal arm rod, which has anti-bending ability and firmness. One end of the support rod 31 is connected to the second end 22 of the collection pipe 2, and the other end of the support rod 31 is fixedly connected to the clamp 32. In one example, one end of the support rod 31 is fixedly connected to the second end 22 of the collection pipe 2 through a hose clamp, and the other end of the support rod 31 is welded to the clamp 32. During use, the metal arm rod can be telescopically adjusted according to the height of the welding operation area, and the collection pipe 2 is fixed at the required position through the clamp 32, so that the collection pipe 2 is accurately located within the welding range. Among them, the clamp 32 can be a high-strength manganese steel spring clip, which provides a pressing force to ensure that the collection pipe 2 is in close contact with the required fixed position, so as to maintain good stability. The high-strength manganese steel spring clip includes two clamping ends 321 and a return spring 322. The return spring 322 is connected to the two clamping ends 321. The two clamping ends 321 are clamped at the required fixed position, and then the metal arm rod is adjusted to support the collection pipe 2, so as to collect the welding fumes in the welding operation area.

[0034] In some embodiments, such as Figure 2 and Figure 3As shown in the figure, a partition 13 is provided in the welding fume treatment chamber 11. The partition 13 divides the welding fume treatment chamber 11 into a first region 8 and a second region 9. The first region 8 is used to collect particulate debris in the welding fume, and the second region 9 contains a liquid 12. In one example, the partition 13 is fixed to the inner wall of the welding fume treatment chamber 11, and the partition 13 has a first hole 131. The collection pipe 2 communicates with the welding fume treatment chamber 11 through the first hole 131 to limit the position of the collection pipe 2 and prevent the collection pipe 2 from moving. At the same time, the particulate debris in the welding fume falls into the first region 8 in the welding fume treatment chamber 11 along with the collection pipe 2. The liquid in the first region 8 adsorbs the welding fume, and the particulate debris in the welding fume is placed at the bottom of the first region 8, thereby effectively adsorbing and purifying the welding fume. In another example, the partition 13 has a plurality of second holes 132. The plurality of second holes 132 penetrate the partition 13, so that the liquid 12 can change back and forth from the first region 8 to the second region 9 through the second holes 132. During the process of collecting welding fume, the collection pipe 2 is firmly fixed in the welding fume treatment chamber 11 containing the liquid 12 through the partition 13. The liquid 12 can effectively adsorb the welding fume, thereby preventing the welding fume from spreading. At the same time, some of the welding fume contains spark debris, and the liquid 12 can quickly eliminate it, thereby ensuring safety and stability. In yet another example, as Figure 1 and Figure 3 shown, the partition 13 has a first hole 131 and a second hole 132. The aperture of the first hole 131 is larger than the aperture of the collection pipe 2. The first hole 131 is used as a channel for the collection pipe 2 to communicate with the welding fume treatment chamber 11. Among them, the liquid 12 is contained in the first region 8 and the second region 9. The welding fume contains smoke and particulate debris. When the welding fume enters the welding fume treatment chamber 11, the particulate debris precipitates in the first region 8. At the same time, there is a partition 13 between the first region 8 and the second region 9, which can better block the particulate debris from floating into the second region 9, thereby facilitating the subsequent separate treatment of the liquid 12 and the particulate debris. The smoke dissolves in the first region 8 or the second region 9, thereby effectively absorbing and reducing environmental pollution.

[0035] In some embodiments, as Figure 1 and Figure 3 shown, a diversion part 14 is provided at the bottom of the welding fume treatment box 1. The diversion part 14 is used to guide the particulate debris to flow into the storage position for subsequent treatment. Each side of the diversion part 14 is inclined, and the diversion part 14 has an inverted trapezoidal structure. The inclined inverted trapezoidal structure of the diversion part 14 can smoothly and centrally guide and store the treated particulate debris, avoiding residue on the inner wall of the welding fume collection chamber 11 and affecting the cleanliness of the welding fume treatment box 1.

[0036] In some embodiments, continue to refer to Figure 3, a collection box 4 is provided below the diversion part 14. The collection box 4 is used to store the processed particulate debris. The collection box 4 can be of a cubic structure, a circular structure, etc., as long as it can store the particulate debris waste. In this regard, there are no excessive restrictions in this application. The collection box 4 is detachably connected to the diversion part 14. Through the detachable connection method, it is convenient to replace the collection box 4 and process the particulate debris waste.

[0037] Among them, a valve 5 is provided between the collection box 4 and the diversion part 14. The valve 5 is used to connect or block the passage between the collection box 4 and the diversion part 14. When the valve 5 is opened, the particulate debris waste in the diversion part 14 flows into the collection box 4 and subsequent processing is carried out. When the valve 5 is closed, the diversion part 14 continues to collect particulate debris.

[0038] In some embodiments, such as Figures 1 to 4 shown, it further includes a converging device 6. The converging device 6 gathers a plurality of collection pipes together and simultaneously allows the welding fume to flow into the welding fume treatment box 1. The converging device 6 is installed on the top of the welding fume treatment box 1. The top of the converging device 6 has a plurality of branch pipes 61. In this application, four branch pipes 61 are provided. The four branch pipes 61 can be used simultaneously or partially. The branch pipes 61 are connected to the second ends 22 of the collection pipes 2. A main pipe 62 is provided at the bottom of the converging device 6. One end of the main pipe 62 extends into the welding fume collection chamber 11 for processing the welding fume.

[0039] In some embodiments, continue to refer to Figures 1 to 4 , sealing rings 7 are provided at both the branch pipes 61 and the main pipe 62 to prevent air leakage in the collection device during the collection of welding fume, thereby affecting normal operation and polluting the environment. In one example, when some of the branch pipes 61 in the converging device 6 are not in use, rubber plugs are used to block the unused branch pipes 61 to ensure the normal operation of the entire collection device.

[0040] In some embodiments, such as Figure 3 and Figure 4 shown, a water inlet pipe 15 and a drain pipe 16 are connected to the outer side wall of the welding fume treatment box 1. The liquid 12 flows into the welding fume collection chamber 11 through the water inlet pipe 15 for adsorption and purification work. Then, the processed liquid 12 is discharged through the drain pipe 16, and the processed liquid is collected through the collection device to ensure that the liquid 12 is clean each time, thereby effectively carrying out the collection and treatment work. Along the thickness direction of the welding fume treatment box 1, the height of the water inlet pipe 15 is higher than the height of the drain pipe 16 to facilitate the discharge of the processed liquid 12.

[0041] Among them, a moving device 10 is provided at the bottom of the welding fume treatment box 1. The moving device 10 can be a sliding wheel or a universal wheel, etc. Driving the moving device 10 to drive the welding fume treatment box 1 to move, so that welding can be carried out in multiple directions and welding fumes can be collected conveniently.

[0042] During use, as Figures 1 to 4 shown, the first ends 21 of multiple collection pipes 2 are connected to the welding fume treatment box 1 through a converging device 6. The moving device 10 moves the welding fume treatment box 1 to the required range. Then, move multiple collection pipes 2 close to each welding operation point, and support them with the support rods 31 on the collection pipes 2. Fix the collection pipes 2 with clamps 32. At the same time, adjust the position of the support rods 31 so that the trumpet-shaped second ends 22 on the collection pipes 2 are located at the welding operation points. And inject liquid 12 into the welding fume treatment box 1 through a water inlet pipe. When welding work is carried out, the welding fumes enter the welding fume treatment chamber 11 through multiple collection pipes 2 and are adsorbed and purified by the liquid 12. After that, the particulate impurities in the treated welding fumes enter the collection box 4 through the diversion part 14, and open or close the valve 5 according to the collection capacity of the collection box 4 to continue to treat the welding fumes. Finally, drain the treated liquid 12 through the drain pipe 16 to complete the welding fume collection work.
