Description

Technical Field

[0001] This utility model relates to the field of welding fume purification technology, specifically a purification device for laser welding of heat sink finned tubes. Background Technology

[0002] The purification device for laser welding of heat sink finned tubes is used to purify the fumes and harmful gases generated during the laser welding process of heat sink finned tubes. The welding fume purification device uses the negative pressure generated by the fan to force the fumes generated during the welding process through the inside of the air pipe device. The fumes pass through the filtration system, and the harmful substances in them are captured by the filter element or filter material, while the clean air is discharged through the air outlet.

[0003] Existing welding purification devices, such as the welding fume purification device disclosed in publication number CN222607507U, although they have the effect of accurately removing smoke from the surface of the workbench, make it inconvenient to replace the filter elements and other filter components in the filter box without contact. Therefore, we propose a purification device for laser welding of heat sink finned tubes. Utility Model Content

The screw 207 is installed, and the rotating wheels 208 are movably installed at both ends of the screw 207. The restraining strips 209 are also arranged and fixedly installed in the placement cavity 201, and the restraining strips 209 are located on the upper part of the filter plate 202. The inner and outer ends of the cover plate 205 are respectively fixedly installed with sealing blocks 210 and sealing strips 211. The outer end of the switching port 204 is also provided with sealing ports 212. The cover plate 205 is also fixedly installed with a card seat 213. The cover plate 205 and the smoke purifier 100 are both fixedly installed with hinges 214. The rotating wheel 208 is also fixedly installed with a pressure plate 215. The rotating wheel 208 is also provided with threaded holes 216, and the threaded holes 216 are matched and connected with the screw 207. The screw 207 is a bidirectional threaded rod.

[0028] Specifically, the purification device for laser welding of heat sink finned tubes is used to purify the fumes and harmful gases generated during the laser welding process of heat sink finned tubes. In this fume purifier 100, the filter plate 202 and activated carbon plate 203 inside the placement chamber 201 can be replaced by first opening the cover plate 205 at the outer end of the replacement ports 204 on both sides of the lower end of the placement chamber 201, so that the new filter plate 202 and activated carbon plate 203 can be directly pushed in from one side. The insertion of the new filter plate 202 and activated carbon plate 203 removes dirt and grime from the placement chamber 201. The filter plates 202 and activated carbon plates 203 are pushed out to avoid direct contact during replacement of dirty filter plates 202 and activated carbon plates 203, thereby improving the safety of replacing filter plates 202 and activated carbon plates 203 inside the smoke purifier 100. The push-in replacement structure inside the smoke purifier 100 via opening the side covers 205 also makes replacing filter plates 202 and activated carbon plates 203 convenient. Furthermore, after replacing filter plates 202 and activated carbon plates 203 inside the smoke purifier 100, the rotor 208... The tightened cover plate 205, through the sealing block 210 and sealing strip 211 at the inner end of the cover plate 205, can also improve the sealing performance of the replacement port 204 after closure, thereby avoiding leakage problems. The fixing seat 206 installed at one end of the smoke purifier 100 is mainly used for fastening the screw 207. The restraining strips 209 arranged and installed in the placement cavity 201 are mainly used for restraining the positioning of the filter plate 202 to ensure the stability of the filter plate 202 and activated carbon plate 203 in use in the placement cavity 201. The sealing at the inner end of the cover plate 205... Block 210 and sealing strip 211 are respectively installed into the interchange port 204 and the sealing port 212 to ensure the sealing performance of the interchange port 204 after it is sealed. The bracket 213 fixedly installed on one side of the cover plate 205 is mainly used to press the rotating wheel 208 on the screw 207 to press the cover plate 205 installed at the outer end of the interchange port 204. The hinge 214 installed between the cover plate 205 and the smoke purifier 100 is mainly used to facilitate the rotation adjustment of the cover plate 205. The pressure plate 215 installed on the rotating wheel 208 is mainly used to press the bracket 213.

[0029] Working principle and usage process of this utility model:

[0030] When replacing the dirty filter plate 202 and activated carbon plate 203 inside the smoke purifier 100, first unscrew the rotating wheels 208 at both ends of the screw 207. After removing the rotating wheels 208 at both ends of the screw 207, remove the retainer 213 that is no longer pressing the outer side of the cover plate 205. At this time, rotate the cover plates 205 at both ends to expose the replacement ports 204 on both sides of the bottom of the placement cavity 201. After the replacement ports 204 are exposed, stack the new filter plate 202 and activated carbon plate 203, and push them in through the replacement port 204 on one side. The new filter plate 202 and activated carbon plate 203 are then installed. In this process, the dirty filter plate 202 and activated carbon plate 203 in the placement chamber 201 are pushed out through the replacement port 204 on the other side, so that the filter components can be replaced without contacting the dirty filter plate 202 and activated carbon plate 203, thereby ensuring safety during replacement. After the new filter plate 202 and activated carbon plate 203 are replaced, the cover plates 205 at both ends of the replacement port 204 can be closed again, and the retainer 213 and the closed cover plate 205 are pressed again by the rotating wheel 208 on the screw 207, so as to complete the safe replacement of the dirty filter plate 202 and activated carbon plate 203.
